Description

Apparaturs and method responsive to the on-boards measuring of the load carried by a truck body

Technical field

The present invention generally is the measurement about vehicle load, and, particularly about the measurement and the acquisition of the designation data of the loading condition of haulage vehicle.

Background of invention

When material carried truck body, because different density of material and/or can be with the ability of the closeer bag tightly of some material bundle, the off highway truck under routine is used is just frequent was used for the widely different weight of load capacity.As a result, truck body just often is filled its volume capacity, and may carry the weight that exceeds the truck load ability.Repeat the result of g-load, cause the too early decline of truck structural integrity, thereby need the replacing of place under repair ahead of time and part.For fear of because damage that g-load caused, even truck body is used for carrying the material of maximal density, it still is mountable to one and really makes the volume that truck can g-load.Though low load can prevent the too early decline of truck structural integrity, this can sacrifice truck load conevying efficiency.Therefore, when the off highway truck of an operation cost costliness during in low load, it is more expensive that its operation cost can become.Thereby must accurately measure the load that is stated from the off-the-road truck.This need stimulate the development of vehicle-mounted weighing equipment, and this equipment is the origin supervision and measures the truck load.

Certainly, carry onboard weight of heavy in order to measure truck, this truck must be packed load cell in its vehicle frame and/or the vehicle body.In a dump truck (dump-body-truck), truck body is being to be situated between to transfer between position and the lifting position to move on the truck frame.Move in order to provide this, vehicle body is general only to be attached on the vehicle frame with a pair of hinge component and pair of hydraulic cylinders.In the dump truck of an ordinary construction, when truck body when transferring the position, its total weight can reach on the truck frame along the buffer interface that is situated between between truck frame and the vehicle body.When car body when transferring the position, hinge component and hydraulic cylinder are not supported the weight of truck body, therefore, they do not reach any tare on the truck frame.By hinge component and hydraulic cylinder being avoided being transferred the load-carrying of truck body, the total stress in these zones just can lower, and therefore prolongs their serviceable life.

Traditionally, in order to provide a vehicle-mounted weighing equipment to this type dump truck, load cell is packed in hinge component and the hydraulic cylinder.So for sensing lead must promote truck body by hydraulic cylinder from its extended position, thereby load weight can reach vehicle frame by hydraulic cylinder and hinge component.Though, by the load measure accuracy that load cell obtained that is associated with hydraulic cylinder and hinge component is gratifying, but the structural integrity of truck can be owing to the adjustment of hinge component and hydraulic cylinder is degenerated, because hinge component and hydraulic cylinder need be equipped with load cell, this can cause concentrating of load on the support.Moreover, transfer the position when a little rising is arranged when vehicle body from it, the impact that falls material to truck bed can especially severe to the truck support.

The structural disadvantages that makes vehicle-mounted weighing equipment than in truck hinge component and hydraulic cylinder load cell being housed it is also important that the shortcoming that the truck body top need be read weight from support.Originally can be used for quality time of loading, transporting and unloading because such needs have spent, and, since on vehicle frame the concentrating of load, truck operators is not just encouraged the load of weighing truck; So, estimate that the load meeting is more quick.Because vehicle-mounted weighing equipment has disturbed effectively and smooth transport operation, so the tendency of not using this weighing equipment is just arranged.Therefore, in dump truck, the advantage of vehicle-mounted weighing equipment just can not realize fully.And, need be in order to obtain weight measurement with the truck body top from support, this can hinder the continuity that vehicle body is done or periodically monitor.

For the weight that dump truck carried is made successional supervision and measurement, be known that the load cell of in truck suspension working pressure meter or kindred type.Generally in this type weighing equipment, at the in-oil cylinder hydraulic pressure of hydraulic suspension by sensing.Because the frictional resistance that the stroke of oil cylinder is short and cylinder barrel is moved big (preceding cylinder barrel is generally also as preceding jack-post), the pressure of being read is just accurately indicated the dead weight capacity of truck unsatisfactorily.Moreover the adjustment that contains the truck suspension of load cell can be opened the possibility that suspension is jeopardously degenerated.

Summary of the invention

General objects of the present invention provides an Apparatus and method for, according to the weight of the material that truck body carried, exactly sensing lead and the transportation parameter.Relevant this point the objective of the invention is to measure reliably and note down the load of truck body and transports parameter, with increase load and conevying efficiency, and the permanent record and the operational circumstances thereof that provide truck to use.

Free-revving engine of the present invention provides an Apparatus and method for, measures and indicate the load and the transportation parameter of truck body, so that this usage degree that expression truck is experienced and the archives of type thereof to be provided.

Another object of the present invention is to utilize load and transportation parameter to prevent to cause owing to the load g-load the unnecessary degeneration of truck structural integrity, thereby prolongs the serviceable life of dump truck.

Further purpose of the present invention is to eliminate a dump truck because the low poor efficiency of utilizing institute to cause load of the mistake of its full capacity is transported.

Other purposes of the present invention and advantage can reach accompanying drawing by the following detailed description and obviously find out.

Tout court, according to the present invention, a vehicle-mounted weighing equipment when the vehicle body on the carriage frame when transferring the position, the dead weight capacity of its vehicle body of continuous monitoring.When carriage frame it transfer the position time, vehicle body places on the vehicle-mounted weighing equipment, so that this equipment forms the interface that is situated between between automobile body and the vehicle frame.One is installed in the sensing processing unit on the vehicle, and the signal that is used to refer to tare from vehicle-mounted weighing equipment is reacted.Through the load signal of vehicle-mounted weighing equipment, this sensor processing unit constitutes a database according to measured vehicle transport performance.Moreover, load signal from vehicle-mounted weighing equipment is to handle with the sensing processing unit, and, the gained data can be transferred to a CPU (central processing unit) by each vehicle, and constitute second database therein, second database by this, CPU (central processing unit) can be given selecteed vehicle by transmission of control signals, to be controlled at load and to dump moving of vehicle between the place.

(3) allow that the depth of parallelism between beam 26,27 and the beam 28,29 changes.

Shown in the right embodiment of hinge component among Fig. 3, the chamber of amplifying 43 of hinge member 30 ' can link to each other with the material 45 and the sheathing 45a of rubber like is to slow down excessively moving of pivot 32 in the chamber of amplifying and to protect the chamber wall to avoid damaging.

Owing to contain the thickness that the thickness of the assembly of the pipe 47 of full of liquid and metal cap 49 equals the vibration-absorptive material that they replace, when truck body moves to when transferring the position, pivot 32 is by the minimum part jack-up in chamber 43.Thus, when truck body 13 was placed down on the parallel girder 26 and 27 of truck frame, the interface that the pipe 47 of the total weight membership full of liquid of truck body 13 and load thereof is provided reached on the truck frame 15.Be supported in the result of the total weight gained of the truck body 13 of transferring the position by the pipe 47 of full of liquid, the rising hydraulic pressure that is detected by pressure transducer 51 just can Quasi be really represented the general assembly (TW) of truck body.The not single physical construction that only provides of the pipe 47 of full of liquid is to measure the general assembly (TW) that truck body was carried, and the shockproof stilt that is situated between between truck body 13 and the truck frame 15 also is provided, between vehicle body and vehicle frame, preset the shockproof propping material of truckmaker.

Generally speaking, pipe 47 is formed (oil is the optimal material of filling this pipe) by the material of anti-oil infiltration.The more important thing is, pipe 47 must not can because of the influence permanent strain of truck body 13 weight.Particularly, pipe 47 should not contain the braided wire of meeting because of any kind of external pressure permanent strain.One example that is suitable for pipe of the present invention is the JAFIB fire hose, and this pipe is made by the anti-company of the Jia Fuli of New Hampshire.For the flexible pipe of any special selection, it must resist consume and wear-resisting.Can be used once the fire hose of revising, the example of one available preferable correction fire hose be three layers of urethane fire hose (that is, the liner that attaches that one deck flexible pipe fiber is arranged the concentric layer of urethane, fiber and urethane) is stamped encapsulant as rubber at the internal diameter of this fiber.

Those are familiar with the people of off highway truck, what can know is that some manufacturer can provide the damping propping material between truck body 13 and truck frame 15, but they can not provide a device, so that be in when transferring the position at truck, make hinge component 17 avoid supporting the part weight of truck body.Such hinge component is expressed out in the most left embodiment of Fig. 3, and wherein pivot 32 is fixed on chamber 43 closely " in.Make the profile of pivot become egg type according to the present invention by the top processing with the crescent profile of pivot 32, the truck of these types just can be corrected, with the total weight of allowing vehicle body along vehicle body one vehicle frame interface and supported.Fig. 3 a has shown the pivot of revising 32, and this correction allows truck body to be placed down in and manages at 447 o'clock with hinge member 30 and 31 separation, thereby makes the pressure of pressure transducer 51 energy measurements from the total weight of truck body.

For school Quasi on truck frame 15 and the lower liquid (that is oil) of pipe 47, one viscosity of full of liquid that is used for being supported on the truck body 13 of transferring the position can be placed on pipe (that is vehicle body is being transferred the position) time at the truck body of sky and is injected in the pipe.This more low viscous liquid is in order to guarantee still that suitable flowability is arranged in winter during temperature.When the beam 26 of the beam 28,29 of truck body 13 and vehicle frame 15 and 27 when parallel, the injection of liquid just can stop.When this position, still have in a small amount between the pivot 32 in hinge component 30 and the minimum part in chamber 43 to contact.Therefore, still have tare in a small amount to be supported on the support 15 here by hinge component 17.For pivot 32 is pushed up from hinge component 30, extra liquid is injected in the pipe 47, can be pushed up till the minimum part in chamber 43 until pivot 32 with seeing.Though anti-U-shaped metal is put 49 and had some down to vertical moving after the truck loading, this moves and is not sufficient to make the pivot 32 and the chamber 43 of hinge member 30 to mesh again.

Be furnished with among the pressure transducer 51a-d of the pipe 47 that is full of hydraulic pressure at each, hydraulic pressure is converted into current potential, and this current potential is connected to the measured value (this can hereinafter discuss) of circuit with calculated weight.With reference to Fig. 4, the pipe 47 of each full of liquid is preferably in the middle section cutting so that the chamber of two fulls of liquid that separate to be provided.Pipe 47 is connected to the independently electronic circuit of pressure reading at the pressure transducer 51a-d of pipe every end of 47 after cutting.After each pipe 47 was divided into two Room, four corresponding pressure readings can be operated with the indication that provides load pressure to distribute, for example, front and back or about overweight, this will discuss hereinafter in more detail.

But in the choice structure of pipe, represent schematically that every pipe can be single, or shown in Fig. 5 a, can form (these less pipes can in bigger pipe) by the pipe of many small cross sections as Fig. 5.With reference to Fig. 6,, in the preferable embodiment of the present invention, there is a contact plate 60 to be fixed on the bottom of the passage that is constituted by cover for a contact area of determining easily is provided between the pipe 47 of full of liquid and cover 49.Pipe 47 is injected into liquid and provides surface of contact with the length along the entire cross section of plate 60.And pipe 47 is not contact with the sidewall of cover 49.Contact weight through 47 bottom surfaces with plate 60 of pipe just can be determined exactly, that is, pressure * area=weight.

The Fig. 7 that leaies through has represented that one contains the more detailed sectional view of the device of vehicle-mounted weighing-appliance.An assembly of being made up of weld 61a, 61b and 61c shown in Figure 7 sets above vehicle-mounted weighing-appliance is fixed to beam 26 and 27.This assembly fits over (beam 27 shown in Figure 7) on each beam.For assembly being fitted on the beam 27, a flat board 62 flushes under beam 27 bottom surfaces, and utilizes nut 63a and bolt 63b to fix in the 61a of assembly and 61b partly respectively, and with reference to Fig. 7 a and Fig. 7, outrigger is fixed on the cover 49 64a and 64b.Be furnished with bolt assembly 190a and 190b between outrigger 64a and 64b respectively, these assemblies are respectively fixed to part 61a and 61b.Because bar 191a and 191b extend outrigger respectively between 64a and the 64b, cover 49 is limited it, and unexpectedly the origin-location breaks away from 47 from managing.The outrigger that moves on the cover 49 and integrally be fixed can make bar 191a and 191b engage with bolt assembly 190a and 190b respectively to 64a and 64b.Simultaneously, cover can respond the weight of truck body and move down.

Assembly 61a-c is installed in the top of beam 27, makes the horizontal surface part 61c on plane provide support face for pipe 47.This horizontal surface is welded to both wings part 61a and 61b, seems the well matched top at beam 27 of saddle on the horse back to allow the 61c of first.Cover 49 and dull and stereotyped 60 is configured in as about the discussion of Fig. 6 on the pipe 47.For to managing 47 and cover 49 stability that level is provided, vertical guide stem 65a and 65b entirely are connected on the opposite end of horizontal surface part 61c on plane.Guide rod 65a and 65b cooperate with the sidewall of cover 49, to prevent to manage 47 move left and right.Shown in the dotted line 27 ' be to be used to refer to beam 27 can replace worker's type beam with the square beam.

With reference to Fig. 8,8a and 9, at every pipe 47 ends one terminal folder 68 is arranged, can keep former whole intact with the interface of pipe 47 and one of them sensor 51a-d in the whole length of life of guaranteeing vehicle-mounted weighing equipment.As shown in Figure 9, the axle collar 70 will be managed 47 and will be retained in the chamber, and this chamber is respectively the top and the bottom 70a of the axle collar 70 and 70b are connected and to constitute.Shown in the exploded view of Fig. 8 a, terminal folder 68 has similar top and the bottom 68a and 68b respectively, and middle body 68c, terminal folder part 68c comprises a center tap hole being used for inserting one of them the ribbed elongated portion of sensor 51a-d, and this ribbed elongated portion is to connect to fix and the end of sealed tube 47.When pipe 47 is used for supporting the weight of truck body 13, owing to there is pressure to act on the pipe 47, so just there is basic masterpiece to be used for the end of pipe.Each end of pipe 47 must come termination to guarantee the method that this Guan Buhui breaks.Metallic collar 70 cooperation folders 68 and one of them sensor 51a-d come the end of limiter tube 47, to prevent pressing from both sides breaking on 68 pipes that provided, the one sensor interface endways.In order further to guarantee between pipe 47 and terminal folder part 68a, 68b and the 68c, on folder one area within a jurisdiction face, to constitute the combination of the last one.This bonding agent also is added on the inwall of end of pipe to help its sealing.As shown in Figure 8, bolt the relevant lower section of going up of the terminal folder 68 and the axle collar 70.

With reference to Figure 10, another embodiment according to vehicle-mounted weighing equipment of the present invention, on the shockproof propping material 52 keeping parallelism beams 26 and 27 to be provided at the shockproof interface between truck frame 15 and the truck body 13, but the beam 28 and 29 of every car truck body all is corrected, and makes them comprise the described vehicle-mounted weighing equipment as accompanying drawing 1-4.Two cross section 29a of beam 29 as shown in figure 10 and 29b, they are to connect with a plurality of bolts 57 that the length along two beams stretches, two beam 28(are not shown) be connected with method with same structure.A kind of two girder constructions that sandwich pipe 47 or load unit (not showing) and provide between two beams, (that is truck body 13 need not be pushed up from truck frame 15) can be measured the general assembly (TW) of truck load exactly according to the present invention.

Though this alternative embodiment need or not the correction of truck frame 15 or packing to the revising of truck body 13, thereby do not have a possibility of the structural fatigue of load support face (that is, truck frame) yet.Moreover, the correction of truck body just will from before one make two, this also is little to the danger that causes the truck body structural intergrity to descend.Particularly, the weight of load is by managing 47 and be distributed in continuously on the length of the interface between two truck bodies, therefore guarantees not under heavy duty and the high stress areas that is easy to break.

In the design of some vehicular manufacturer's truck, when truck body 13 when transferring the position, the weight membership hinge component of truck body is supported on the back end of vehicle body, and the quite little truck frame interface zone of mat is supported on the front end of vehicle body.When vehicle body when transferring the position, as shown in figure 12, dangle on support between two supporting zone vehicle body zones.Concerning the truck body of these types, on the length of the parallel girder of vehicle frame, there is not shockproof propping material.When this truck body when transferring the position, interface zone 55 on the beam 27 of support 15 relatively an end of hinge component 17 support the beam 29 of truck body 13, thereby prevent that vehicle body is in the cantilever situation.For these types of cards bassinet structures, when vehicle body when transferring the position, owing to be supported on the truck frame 15, just be respectively to place the load cell 57 of interface zone 55 and the load cell 59 of hinge component 17 according to vehicle-mounted weighing equipment of the present invention with two truck bodies of naming a person for a particular job.The specific example that is suitable for a load cell of Figure 10 embodiment is antifatigue load cell (model 3116 or 3152), and this load cell is made by the Lai Bao affiliated company in Michigan, USA Troy city.

Hinge component 17 places is the method for another alternative placement load cell 59 in Figure 12, this load cell can place beam 27 and 29(shown in Figure 12 59 ') between interface on, if needs are arranged, hinge component 17 can be corrected to provide just like Fig. 3.Shown " floating " joint pin.Unsteady joint pin has been arranged.Unsteady joint pin has been arranged, the weight of truck body will be fully along the interface between beam 27 and 29 and supported, therefore, the load cell 7 and 59 ' accurate indication of a tare can be provided.As a further alternative, when keeping load cell 59, the shortening type of vehicle-mounted weighing equipment can replace load cell 57 among Fig. 1-9.

With reference to Figure 13 a, heavy off highway truck comprises a pressure transducer, and this sensor is added on the hydraulic tube that links to each other with hydraulic cylinder 19 and 21; Through the pressure survey that hydraulic tube provided from hydraulic cylinder 21, the pressure survey that provides by vehicle-mounted weighing equipment is provided, the load weight that will just can determine respectively for the moment addition of hinge component 17 on antero posterior axis 71a and 73a distributes, through will be for the moment addition of hinge component 17, the centre of gravity place of the weight that is carried by truck body 13 just can determine.Through the centre of gravity place of the weight that is carried by truck body 13 that is determined, the relative distribution of load general assembly (TW) on antero posterior axis just can determine.

In order to determine axle load, truck 11 can be illustrated among Figure 13 a and the 13b with graphic mode as a horizontal line 74 by antero posterior axis.The vertical height of in fact, load center of gravity is unimportant; Therefore, provide the one dimension position of load center of gravity about the moment equation (vertical height of hinge also is left in the basket) of hinge component 17, the dead axle load of fighting to the finish of this position is important, that is be center of gravity in the position of antero posterior axis.

Shown in Figure 13 a and 13b, in order to determine along the load centre of gravity place of the length of truck 11, truck body just needs shown in the distance h of Figure 13 b to transfer position or jack-up slightly from it, so that hydraulic cylinder 19 and 21 provides a pressure reading that is used for making truck body required power when hinge serobila 17 rotates.By on horizontal line 74, engrave as the time inch formula predetermined unit, just center of gravity can determine with respect to the horizontal shift of antero posterior axis.

Since among Figure 13 a and the 13b hydraulic cylinder 19 and 21 be for the Z-axises that hang down mutually with horizontal line 74 at angle Φ install, the cosine that must multiply by cylinder area (being used to provide pressure survey) and angle Φ from the pressure reading that fits over hydraulic cylinder 19 and 21 upward pressure sensors calculates, with the pressure at right angle of decision at cylindrical hinge assembly 33 places.Though angle Φ can change with the extension of hydraulic cylinder 19 and 21, but because 13 of truck bodies need lifting (distance h shown in Figure 13 b) the angle Φ that makes trace just to can be considered the purposes of a constant as the load of decision reference axis, and in the storer of the processor that the predetermined value of this angle Φ more can be stored in hereinafter to be discussed, this processor is to cooperate vehicle-mounted weighing equipment to use.

After decision, just have only a unknown number in the pressure at right angle of cylindrical hinge assembly 33 for hinge component 17 and along the moment equation of transverse axis, that is, the horizontal range from vehicle body hinge component 17 to center of gravity.Following equation is represented the moment relation for vehicle body hinge component 17:

(general assembly (TW)) be (cos Φ) (y+z)=0 (1) (C/C)-(cylinder weight)

Wherein " general assembly (TW) " is the up-to-date pressure reading from vehicle-mounted weighing equipment, and the load that expression truck frame 15 is carried and the product of a predetermined constant are to provide a pressure survey; And C/C is the load centre of gravity place that is projected on the horizontal line 74, and " cylinder weight " is from multiply by cylinder area at hydraulic tube to the pressure of the pressure transducer between hydraulic cylinder 19 and 21; Angle Φ is made of the longitudinal axis 75 of cylinder 21 among Figure 13 a and the 13b and 76 on the axle that hangs down; And (y+z) be in the distance between vehicle body hinge component 17 and cylindrical hinge assembly 33 on the horizontal line 74.Solve centre of gravity place, equation is expressed as follows:

C/G=((cylinder weight)/(general assembly (TW))) (cos Φ) is (2) (y+z)

Find out the horizontal level of center of gravity, use heavily solves the load that just can determine on each for axletree and along the arm of force of horizontal line 74 with axle.With regard to front axle, for the arm of force and the equation that the load of answer front axle is provided of rear axle.Equation for the arm of force of rear axle is expressed as follows:

(in the weight of front axle) (W)-(general assembly (TW)) (C/G-Z)=0 (3)

Solve the weight at front axle, equation just becomes:

Weight=(general assembly (TW)) ((C/G-Z)/(W)) (4) at front axle

In order to find out the load on rear axle, front axle power taking arm is made following equation:

(in the weight of rear axle) (W)-(general assembly (TW)) (W+Z-C/G)=0 (5)

Weight=(general assembly (TW)) (1+ (Z-C/G)/(W)) (6) at rear axle

Weight support frame (that is tare weight) at the truck 11 of being born on the antero posterior axis can add on this calculated weight the general assembly (TW) of being born to be provided on the antero posterior axis.In order to find out the tare weight on the antero posterior axis, truck 11 can be simply once one of weighing on the weighbridge shown in Figure 15 a-b.In the process of measuring tare weight, truck body 13 can be removed from truck 11, and perhaps the weight that belongs to antero posterior axis of vehicle body can deduct from the weight that weighbridge (Figure 15 a-b) noted down.The result of weight measurement can be stored in hereinafter described the circuit memory, and this circuit is to cooperate vehicle-mounted weighing equipment to use.

Because to represent the value of w, x, y and the z of horizontal range is known, and when truck body 13 slightly pushes up from vehicle frame 15, hydraulic cylinder 19 and 21 pressure are known, and the center of gravity of load (coming weighing by vehicle-mounted weighing equipment) can be decided by equation (2).The center of gravity of load is once decision, and the load distribution between antero posterior axis 71a and 73a is just easily decided by equation (4) and (6) respectively.

The similar approach of utilizing the off highway truck of Figure 13 a-b to deliver can determine the axle load of other types off highway truck.For example, expression is scraped the lifting of navy barrow and is transferred the position respectively in Figure 14 a and 14b, and use one is estimated the antero posterior axis load of scraping navy barrow with the pressure transducer that lifting cylinder barrel 82 links.Scrape navy barrow the openend of vehicle body is transferred to contacting with ground the vehicle body of will material on the ground packing into.Move forward when scraping navy barrow, material is on the ground swept by the opening of transferring in the vehicle body of scraping navy barrow.Also that is to say the scraping ground, base of vehicle body, " scraping navy barrow " therefore by name.

The physical construction that Figure 14 c-d represents to scrape the lifting of navy barrow 81 and transfers vehicle body 83 in mode the most clearly.When vehicle body when promoting or transferring the position, promote cylinder barrel 82(and only represented one) with vehicle body 83 tops overhead.In order to prevent that material from dropping out from vehicle body 83, there is a gate assembly 84 to be used for transferring or the opening of vehicle body 83 being closed during raised position when vehicle body 83.The control of gate assembly is to be provided in a well-known mode by connecting rod 85.

Refer again to Figure 14 a, longitudinal size V, W, X, Y and the Z of bull-clam shovel 81 is used to calculate about axle load of antero posterior axis 86 and 87 respectively.Mode with the axle load that is used to determine off highway truck is the same, is with the instrument that decides axle load for the arm of force of antero posterior axis.Different with off highway truck is, the center of gravity of load and be not easy decision in the vehicle body 83 of scraping navy barrow 81.In the off highway truck of Figure 13 a-b, vehicle-mounted weighing equipment is combined in pressure transducer in the lift cylinder cartridge system to find out the center of gravity of load.In scraping navy barrow 81, the load center of gravity of scraping navy barrow vehicle body 83 need be estimated.For purposes of illustration, the navy barrow 81 of scraping among Figure 14 a is had a center of gravity by hypothesis on the pivoting point 88 of pivot arm 89.The centre of gravity place of hypothesis has been arranged, and the general assembly (TW) of load just can determine, the result, and the power on axle also can be determined.

For the reference axis load, the weight of load must at first be determined.When vehicle body 83 during, convert the pressure of jack cylinder 82 to a power and must think the weight of vehicle body 83 and solved to allow about the arm of force of front axle in raised position.Because jack cylinder 82 is a low-angle Φ, power F with perpendicular line ₂Must multiply by cos Φ to obtain vertical force, as the arm of force that calculates about front axle.This equation is expressed as follows:

0＝（cosΦ·F ₂V）-F ₁Y （7）

F ₁V＝F ₂V·cosΦ

F ₁＝F ₂V· (cosΦ)/(Y)

F wherein ₁Be tare 83 and F ₂Be power at jack cylinder 82 place's jack-up vehicle bodies.

Load weight is after decision, and axle load just easily is calculated as follows:

0＝F ₁Y-F ₄W （8）

F ₄＝F ₁(Y)/(W)

F wherein ₄Be the weight at rear axle 87 places, and

0＝F ₁Z-F ₃W （9）

F ₃＝F ₁(Z)/(W)

F wherein ₃Be the weight at front axle 86 places.More than calculate and to carry out with circuit and the process flow diagram discussed among accompanying drawing 16,17 and the 18a-r.Though process flow diagram delivered utilize vehicle-mounted weighing equipment and promote cylinder barrel collected data calculate the step of the axle load of dump truck, can know from above discussion of scraping navy barrow that similar software steps accompanying drawing 16 and 17 can be used for calculating and scrape navy barrow tare and axle load.

As summary early, the platform pound of Figure 15 a-b can be used to scrape among off highway truck among the survey sheet 13a-b or Figure 14 a-d tare weight of the antero posterior axis of navy barrow.Tare weight is to be stored in the electronic memory in " hard number " mode, and this tare weight also adds with the axle heavy phase of calculating from load, to draw total axle load.The example of a pound can be realized vehicle-mounted weighing equipment as appropriate change.Particularly, briefly with reference to Figure 15 a and 15b, one inexpensive pound is illustrated out with the pipe, sensor and the supporting construction that are similar to vehicle-mounted weighing equipment.Many tube coupling 90 is placed under dull and stereotyped 91., be combined in the marketing of two on flat board 92 and be received within the corresponding sleeve pipe 93 that is combined on the base plate 94 in case slide for flat board 91 is fixed on a settling position.Sensor (not showing) is connected to an end of every pipe 90, and perhaps, inclined to one side by pressure in central authorities as pipe, sensor can be connected to each end of pipe.

One contact plate 95 will be managed 90 and will be connected to dull and stereotyped 91.Contact plate dull and stereotyped 91 and manage 90 between keep a fixing contact area.In order to prevent that pipe from drifting about on base plate 94, every pipe 90 is adjacent to the protrusion part 96 of giving prominence to from base plate 94 along its length.In when operation, the platform pound is hidden into underground so that dull and stereotyped 91 fit into a plane with ground.For the front or rear axle of truck among weighing such as Figure 13 a and the 13b, truck operators only need truck sailed on the platform so that all wheel be carried on the flat board.The pressure that is increased in 90 at pipe is by as shown in figure 16 pressure transducer and electric circuit inspection, and with indivedual pressure reading additions with it with convert a weight measurement to.

Referring now to Figure 16, being to be regarded as " processor apparatus " in the past by sensor processing unit 101(by handling the circuit of finishing Weighing system from the pressure data of vehicle-mounted weighing equipment) institute provides.This unit preferably is based upon on the microprocessor.People with skilled technology can know obviously that sensor processing unit 101 is called CUP 103 below comprising a CPU (central processing unit) 103(), a boostrap memory 105 and a read/writable memory device RAM 107 who constitutes with the PROM form.First storage function partly of RAM 107 is from first storage array of the pressure reading of vehicle-mounted weighing equipment (below be called the array I) as storage.Array II and III are used separately as always takes into account archival memory.These storage arrays will be described in a more detailed discussion with accompanying drawing 16a.An example that is suitable for as the CPU of sensor processing unit 101 is a Z80 microprocessor, and this microprocessor is made by the Intel company of Santa Clara City, California, America.Another feasible microprocessor is 8085 of Intel Corp.'s manufacturing.

In the general structure, what draw from CPU 103 is a microcomputer bus 109.Bus 109 connected storages 105 and 107, and input port 113 and 115.Microcomputer bus 109 drives 121 by display driving 120 and printing machine respectively and reaches visual display unit 117 and printing machine 119.For sensor processing unit 101 being provided operator and truck numbering, microcomputer bus 109 links by interface 124 and keyboard 122.Keyboard 122 also provides a conversion factor will store the gravimetric value that pressure reading converts ton, pound or kilogram to for sensor processing unit 101.And what reach sensor processing unit 101 by microcomputer bus 109 is a clock 126.For in sensor processing unit 101, provide communication path between printing machine 119, virtual display unit 117, clock 126 and the keyboard 122, microcomputer bus 109 comprises data line, storage line and control line.

In order to measure the axle load of truck 11, interrupt instruction meeting indication sensor processing unit 101 goes to carry out and utilizes the pressure reading of vehicle-mounted weighing equipment and pressure transducer 139 to come the software program of reference axis load.As shown in figure 16, truck operators can start look-at-me by a button 142.As narration, interrupt only after the elongation of operator's mat hydraulic cylinder 19 and 21 promotes truck body 13 a little, just starting about accompanying drawing 13.

As previously mentioned, draw and can number with a special identity through the transportation parameter that sensor processing unit 101 is handled and to discern, thereby the indication of truck and operator's characteristic is provided at vehicle-mounted weighing equipment.What have that the people of skilled technology can know is, keyboard 122 also can be used as skilled worker, oil supplier and other maintenance personals' identity input, with the maintenance job (in the 5th array of RAM 107) on the record truck and carried out maintenance job personnel's identity.About record user's identity numbering, sensor processing unit 101 can control ignition be blocked device 127, and only when correct identity numbering was admitted, this device just can allow truck 11 start.When truck not in when walking, for the change that makes sensor processing unit 101 detecting operation persons numbering (as, change over oil supplier's identity from skilled worker's identity) sensor processing unit connected with the mains continuously.In well-known method, when truck was flame-out, sensor processing unit 101 was replied standby condition, can reduce power consumption like this, thereby prevent the serious electric leakage of battery supply.When standby condition, whether sensor processing unit is periodically powered and looked over its sensor input end starts.If for example there is new identity numbering to be transfused in the keyboard 122, new numbering can be stored in this unit, and printing and/or show a data summarization.Truck is controlled by previous numbering as far as possible.(demonstration of this data summarization will be explained in more detail in accompanying drawing 18h).As another selection with keyboard 122 input identity numberings, the operator also can use calculating punch to read in coding card.

Sensor processing unit 101 and associated electronic components thereof react on the startup of engine and are energized, and this will explain in the process flow diagram of accompanying drawing 18a to 18m in more detail.One engine that starts starts CPU 103, these CPU 103 recovery routine storeies, thereby the routine of process flow diagram among beginning Figure 18 a-18m.

The circuit that the available embodiment of the vehicle-mounted weighing equipment that each is different all has Figure 16 together with one with the analog electrical signal of the linear ratio of pressure, this pressure is applied and is got by the pipe liquid on the sensor 51a-d of this equipment.(used in preferable embodiment is pipe or load cell, in available embodiment used be strainmeter or similarly pressure sensing change change device).Because the pressure of pipe liquid and the linear ratio of weight of truck body 13 owing to the hydraulic pressure of sensor 51a-d with linear mode reflection pipe, should just be directly proportional with truck body weight from the simulating signal of sensor again.

As discussing about accompanying drawing 13a and 13b, sensor 135,137,138 and 139 to cooperate vehicle-mounted weighing equipment be that sensing processing unit 101 is submitted necessary information, and thinks that truck operators provides the output information as load on antero posterior axis.Shelves sensor 135 with keep function to be used by the performed record of the software of sensor processing unit 101, just can be in response to the gear shift of truck operators, and be stored in RAM 107 and the information that obtains from vehicle-mounted weighing equipment also can be by computing (explanation that this is will be the process flow diagram of Figure 18 a-18r more complete).Under similar situation, when dumping sensor 137 indication truck bodies 13 and go to emptying position, dump sensor 137 and just made and be used for computing from the storage data of weighing equipment onboard by sensor processing unit 101.It is contained in and dumps preferably mercury switch of sensor on the truck body 13, so that can react with the variation of vehicle body position when dumping a load.Known to applicant, mercury cut-off does not resemble those mechanical switchs that is used for legacy device, and when mercury cut-off was used as tilt switch, it was owing to environment around isolating has highly favourable characteristic.Therefore, the severe rugged environment that off highway truck often ran into just can not cause switch performance to fail fast.

Sensor processing unit 101 service range sensors 138 are done range observation, and calculate ton mile/hour unit that is used to refer to wheel wearing and tearing or usage degree.At last, pressure transducer 139 is placed on the hydraulic tube of hydraulic cylinder 19 and 21, and provides pressure survey to be used for calculating the axle distribution of total load.Interaction meeting between sensor processing unit 101, vehicle-mounted weighing equipment and each sensor is described in a more detailed discussion in the routine of the sensor processing unit that the process flow diagram of Figure 18 a-18r is delivered.All all are simulation devices with upper sensor, and they need be with the conversion of the represented analog to digital of A/D functional block 130.Owing to comprise that the circuit of A/ D converter 129 and 130 all is traditional, therefore will not describe in detail.

For the indication directly perceived of the load-carrying capacity that is not used that truck body is provided, sensor processing unit 101 links by microcomputer bus 109 and thermote 140.Thermote 140 contains multi-lamp 140a-e, and they are overlapping in one folded one mode.Utilize indicator 140 last other lamps to start, sensor processing unit 101 just can provide the signal that is proportional to the bucket load to loader operator, so that can come safely load to be added to truck in the scope that is no more than the truck load capacity.Carry through a predetermined maximum load appearance that is stored in the sensor processing unit 101, sensor processing unit 101 just can decide the residue load-carrying capacity of truck body 13 from the measured current load of vehicle-mounted weighing equipment.

If truck is to load with continuous material stream, rather than loads discontinuously with the bucket of front-end loader, just indicator 140 can provide indication actual time of residue load-carrying percentage by volume.For example, if use travelling belt or funnel (not showing) to load truck 11,, and start a suitable lamp 140a-e according to the percent of residual capacity just sensor processing unit can be with current load data and maximum load comparison.In this example, can watch the residual capacity of pilot lamp 140a correspondence 20%, the residual capacity of pilot lamp 140b correspondence 15% etc. attentively.When truck near full load, but lamp 140a-e aid forecasting of this order when continuous material stream is cut off, avoiding overflow, but still guarantee to have a maximum load.Be used to provide residual capacity actual time indication the individual programs step not in following Figure 18 a-r the step of process flow diagram illustrate, but for the programmer, the program of continuous material stream load mode clearly needs from this process flow diagram change, and this string routine has been described each step that adds and react with increasing progressively.

About the indication of truck residue load-carrying capacity, the average recruitment of truck body weight when the lotus thing of the every shovel loader bucket of sensor processing unit 101 decisions adds to truck body 13, thus indication is used to load the average weight of a bucket lotus thing of truck body.If the average weight of a bucket is less than the residue load-carrying capacity of truck body 13, just the green light 140a of indicator 140 can be started by sensor processing unit 101.If the average weight of a bucket is greater than the residue load-carrying capacity of truck body 13, sensor processing unit 101 can decision remain much percent that the load-carrying capacity the most closely is estimated as the average weight of a bucket.

Particularly, if the residue load-carrying capacity of truck body 13 has the value between the overall average weight of 3/4ths and one bucket lotus thing of the average weight of a bucket lotus thing.3/4ths lamp 140b just starts.In order to light 1/2nd lamp 140c, the residue dead weight capacity of truck body 13 must between the average weight of a bucket lotus thing 1/2nd and 3/4ths between.Similarly, in order to light 1/4th lamp 140d, residue load-carrying capacity must between the average weight of a bucket lotus thing 1/4th and 1/2nd between.At last, thereby be fully loaded in order to put send out a warning 140e and indication truck body 13, the residue load-carrying capacity of truck body 13 (this can be determined by the pressure reading from vehicle-mounted weighing equipment) must be less than 1/4th of a bucket loading average weight.The operation of the indicator 140 that the pressure reading in response to from vehicle-mounted weighing equipment by sensor processing unit 101 carries out will be in the process flow diagram about Figure 18 a-18m gives more detailed description in the routine of illustrated sensor processing unit.

Wireless set 150 is installed on the position suitably and easily of truck 11, so that sensor processing unit 101 can be communicated by letter with central computer.Just as the traffic-police, control is between the truck stream that loads and dump between the place as the central computer that hereinafter describes in detail.

The calibration and the procedure operation of vehicle-mounted weighing equipment and the sensor processing unit 101 of now leafing through, the initial of system makes an explanation with reference to preferable embodiment of the present invention.Those are had the people of skilled technology, can it is evident that by the calibration of following vehicle-mounted weighing equipment to the preferable embodiment of the present invention and the procedure operation of sensor senses unit, about the present invention

The calibration and the program storage of the available embodiment sensor processing unit 101 of vehicle-mounted weighing equipment all need be revised.

The calibration of vehicle-mounted weighing equipment can illustrate through the situation of the truck body 13 of considering to have ten tons of curb weight and 50 tons of lifting capacities.In the preferable embodiment of vehicle-mounted weighing equipment,, 40 pounds of/square English inch are arranged by empty calorie car vehicle body 13 formed pressure if manage the 47 total synthetic useful area with one 500 squares of inch.One laden truck vehicle body 13(that is 50 tons) form the pressure of 240 pounds of/square English inch.Utilize pressure transducer 51a-d and linking of pipe 47 just can obtain an analog output voltage, this voltage can be measured 0 and 300 pound of/square pressure between the English inch exactly.The analog electrical output of sensor 51a-d is pressed between 2 to 6 volts and changes.For having the truck body 13 of ten tons of curb weight and 50 tons of load-carrying capacity,, it is 2.53 volts and be 5.20 volts for all-up weight from the aanalogvoltage of sensor 51a-d for empty calorie car tare.Therefore, it is 2.67 volts from the unloaded voltage range that output voltage had to fully loaded sensor.

Below analog digital converter 129(, be called A/D converter) in, understand self simulation voltage from the output voltage of each pressure transducer 51a-d and change into digital signal.Output from A/D converter 129 is the decimal number of a binary code, because this aanalogvoltage digital and from pressure transducer 51a to 51d is directly proportional, therefore, this numeral also is directly proportional with pressure of pipe 47.Because the voltage output range of pressure transducer 51a-d is between 2 and 6 volts, A/D converter 129 converts the decimal number (being produced a zero load condition when truck body pushes up from sensor) that a numerical value approaches a binary code of 0 to 2 volts, and converts the decimal number that a numerical value is about 255 binary code to 6 volts accordingly.

This is had the example truck 11 of the vehicle body 13 of ten tons of curb weight, when truck body when transferring the position, it is 34 decimal number that above calibration process can provide a numerical value at the decimal numeral binary code output terminal of A/D converter 129.Representing unloaded numerical value is that 34 decimal number and 50 tons are relatively fully loaded, and the latter is that numerical value is 204 decimal numeral binary code in the output of A/D converter 129.Therefore, representing the truck body load is 170 from unloaded extremely fully loaded decimal numeral numerical range.So, pressure limit (this scope weighs scope corresponding to zero load to fully loaded dress) along with 200 pounds of/square English inch just provides one to be about 1.18 pounds/square inch/decimal numeral resolution characteristic from A/D converter 129 with the scope 170 that decimal numeral binary code is represented.

Measure weight (that is ton, pound or kilogram) in order to calibrate vehicle-mounted weighing equipment with suitable unit, one is used for proofreading and correct between dull and stereotyped 60(Fig. 6) and desired unit of weight between the conversion factor of contact area be by in the keyboard 122 that manually is set in Figure 16, and this factor is converted to decimal numeral binary code by the traditional circuit that links to each other with keyboard.This decimal numeral binary code is delivered to CPU 103 by interface 124.In CPU 103, this conversion value can multiply each other with a decimal numeral binary code, the net pressure of the truck body that this binarization yardage word representative was calculated in the past.The decimal numeral binary code product that is drawn can according to selected conversion factor come with ton, pound or kilogram the numerical value of unit representation truck body net weight.The net pressure that pressure transducer during for example, from full load condition is calculated can be 170 decimal numeral binary code corresponding to a numerical value.CPU 103 will from the decimal numeral binary code of keyboard 122 come with this numerical value be that 170 binary code multiplies each other.

In order to isolate the accurate measurement that obtains pressure on the tube couplings 47 at those four, sensor processing unit 101 can be on each pressure transducer 51a-d continuously with voltage reading 16 times.In order to obtain the pressure value of each sensor 51a-d, these 16 readings can be by average.Next sensor read and reading by before average, each pressure transducer 51a-d is all read and on average.When all pressure transducer 51a-d were read and their 16 separate readings by after average, 4 average readings of gained can be by average and be obtained the pressure survey of a truck body 13.Because the net weight of truck body 13 is the weight of being concerned about, tare weight (being stored in the storer as the pressure of being scheduled to) is deducted from the mean pressure reading of pressure transducer 51a-d just obtain a net pressure reading.The load weight that is carried by truck 11 in this net pressure reading and the truck body 13 is corresponding.This reading is stored in the array I, and according to processed for the program storage of 103 uses of the CPU among the PROM 105.

In order to convert above pressure reading to weight readings, see Fig. 7 between pipe 47 and dull and stereotyped 60() significant figure touch area and must be multiplied each other.The pressure data of sensor 51a-d is represented the weight of unit area.Effectively contact area and pressure reading multiplied result are the data indications of weight.The method of finding out weight has two:

(1) total effective area with all flat boards 60 of this mean pressure and vehicle-mounted weighing equipment multiplies each other.

(2), and multiply each other with it with the useful area of one of them flat board 60 with the separating pressure addition of every sensor 51a-d.

By the experimental study gained, applicant finds that dull and stereotyped 60 surface area is not to use the accurate area that multiplies each other with pressure.And the surface area that need revise slightly once one, increase is made Weight Calculation.The degree that increases is by the experiment decision.Certainly, the result of pressure * area also must change to provide as suitable unit of weights such as pound, kilograms.

Calculate in order to make above weight, the effective contact area between Jie's pipe 47 and dull and stereotyped 60 of each sensor 51a-d is regarded as identical.If specific system design causes having unequal area, just each pressure and area must be handled dividually.Therefore, if four pipe joints 47 among Fig. 1-4 contain leading portion and two long back segments of two weak points, two short leading portions must be handled dividually with back segment, calculate so that significant indivedual weight to be provided.

In order to write down the relevant data that electronic circuit provided by vehicle-mounted weighing equipment and Figure 16, the RAM 107 that is formed (for example: status flag) does not singly contain the required various temporary storages of regular software operation, and more contain and be used for the data cell array of storage time and pressure data, so that the chronological record of a truck and operator's performance to be provided, and provide the further data indication of a database with extraction performance.With reference to Figure 16 a, RAM 107 schematically is illustrated and contains a multiple storage area and seven arrays at least.

The array I provides storage location for a plurality of continuous net pressure numerical value, and this numerical value is to calculate and get from the pressure data of the pressure transducer 51a-d of vehicle-mounted weighing equipment.In RAM 107, also have the memory location as the summary catalogue that will transport parameter, and summary wherein that to be the mat operator number is indexed so that every operations of operators performance of truck 11 all can be quantized.For example, array II and III are arranged among the RAM 107, wherein the array II is to collect the summary of the transportation parameter of a duration, and this duration is to begin to measure till this numbering change after an operator numbers this system of input.The input of individual operation person numbering can be discerned a certain unit in second array being used for receiving the summary of transportation parameter, thereby available this operator discerns this summary.Through the nonvolatile memory that is provided for RAM 107, the array III is regarded as the filing of array II summary, and (for example: January, a season or 1 year) operator operates record thereby a time cycle that comprises the person of being operated repeated use is provided.

One the 4th array (array IV) provides one storage area to be arranged with the maintenance job on the record truck.The relevant data that is used to refer to user's identity numbering that maintenance personal rather than driver import and is time of controlling with resembling under this repair number etc. is stored in the array IV.The data that two additional array V and VI are stored are the performances that are used for estimating heavy off highway truck.The data that array V and III are stored relate to real time of being increased by the weight of added each the bucket load of shovel loader and every bucket, and this will be in hereinafter discussing in more detail.The array I respectively store to the VI the purpose of data and operation in conjunction with the accompanying drawings 18a-18m process flow diagram and discussed.

At last, the array VII is one to be used for storage is reached the data in remote central place to set up the zone of historical archives from system onboard.Relevant data can both one of or both side by side be shown to reach onboard and reach central computer, this will be apparent in the discussion about the process flow diagram of accompanying drawing 18a-m and 20a-b.As to be transmitted be selected, and data can temporarily be stored in the array VII, and are transmitted with the suitable control signal from central computer that is received.

More simply reach in the equipment of less expensive one, the circuit of Figure 16 can be replaced by mechanical weighing indicator 169 by shown in Figure 17 a-c.Sensor 51a-d is removed from managing 47, and oil is continuous to one of them plunger shaft 170a-d from each pipe.In each plunger shaft 170a-d, a piston 171a-d is arranged, and with foreshortened figure in Figure 17 c to represent the example of a piston.Each piston 171a-d is a plate-like, and utilizes O shape ring 172a-d that chamber 170a-d is sealed to volume up and down.

Since the weight of truck body 13 with from the pressure of many pipes 47 of vehicle-mounted weighing equipment be directly proportional, this machinery weighing indicator 169 is with separating pressure and utilize traditional pressure gauge 175 to show general pressure.This system is once calibration, and pressure gauge 175 just can replenish with weight scale, so that weight can directly directly be read from pressure gauge.From following description as can be known, more if desired pressure input end, additional piston 171 and plunger shaft 170 can easily add to indicator 169.

With reference to Figure 17 b, folded ground of a plurality of plunger shaft 170a-d is overlapping, and as shown in the figure, the piston that they contain is to link with longitudinal axis 176b-d.Each bar axle 176a-d reaches the power of its next piston in the piston of itself.Thus, it can the be come up power of comfortable secondary piston of the piston after is added on the power from oil pressure, and will have and reach another piston thereon by axle 176, so analogizes.Last piston just have from other all pressure of lower piston and.Owing to do not have piston under the lower piston 171a, so it does not need axle 176.

For all power of a piston can be reached on another piston, the top volume of each piston (at last or except the upper piston) is to communicate with atmosphere by air hole 177a-c.Certainly, oily inhalation port 178a-d is the bottom volume that is arranged in every chamber 170a-d.For the oil-overflow volume in bottom is separated from its adjacent top ventilation volume, chamber 170a-c contains disc portion 179a-c respectively.These parts contain the medium pore 180a-c that is used for inserting a 176b, c and d respectively.Every medium pore seals with lining ring.The not end of endless groove 181 at every chamber 170a-d arranged, be used for inserting O shape ring to form sealing indicator 169.Each plate-like part 179a-c all contains recess below thereon to admit cylindrical cavity 170a-d.

Under assembled state, mechanical weighing indicator 169 is respectively dull and stereotyped 182 and 183 to cover up and down.Many bars 184 among Figure 17 a should save indicator 169 extensions and will dull and stereotyped 182 and 183 engage up and down.The thread end of bar 184 connects nut with fixing whole assembly.

For pressure that can balanced incoming line when the installation of indicator 169, valve 185a-c will be from the incoming line interconnection of vehicle-mounted weighing equipment, and when mounted, valve 185a-c opens, and hydraulic pressure can be equated.Then valve 185a-c is shut, when normal running, they also keep shutting.Every incoming line from pipe 47 has a throttling valve 186 to arrive hydraulic ga(u)ge 175 with the unexpected variation (that is pulse) that prevents pressure.On every incoming line and an air column 187 is arranged to prevent that vehicle-mounted weighing equipment under the occasion of remarkable weight uneven distribution, having the possibility that vacuumizes.Top and the equal full of liquid of end volume of upper plenum 170d are to pass to pressure gauge 175 by top volume and output port 189 with additional pressure.

In simple system, mechanical weighing indicator can be positioned at outside the truck and be contained in a fixed location.For example, load equipment is fixed when loading, and the tube coupling tolerable loader operator between vehicle-mounted weighing equipment and the stationary machine weighing indicator need not utilized quite expensive wireless set and the weight of monitoring vehicle load remotely.In such system, sensor 51a-d disappears significantly, and the tube coupling between vehicle-mounted weighing equipment and the mechanical weighing indicator is a simple catheter, so that fluid under pressure is reached this fixed location from truck.

In order to allow the vehicle of load remove from loading the place, the tube coupling between vehicle-mounted weighing equipment and the mechanical weighing indicator 169 contains the quick disconnector material of a traditional design.When operation, vehicle moves to a position and loads, and the protruding and female part of quick disconnector material engages to allow that the pressure from vehicle-mounted weighing equipment directly reaches on the stationary machine weighing indicator 169.Because charging appliance is fixed, indicator preferably directly is contained on the shovel loader, so that loader operator can monitor the load weight that increases.When fully loaded being shown, the quick disconnector material separates pop-up indicator 169 with vehicle-mounted weighing equipment, removes so that this truck can load the place certainly, and allows that new truck location is to load.Truck that this is new such as preceding ground coupling machinery weighing indicator 169, and repeat above step.What above hydraulic system was had obvious change is its to be improved become power driven system, and wherein sensor 51a-d places on the vehicle-mounted weighing equipment, and a transmitter provides, pressure data is reached the device on the projection electronic weighing indicator that is positioned at shovel loader.Certainly, need as the pressure data reduced form sensor unit 101 of transmission in order to prepare.The weighing quantity fixing indicator can be a data receiver, and it becomes a weight to show the transmission pressure data-switching for loader operator.

Referring now to the process flow diagram of Figure 18 a-18m, the process flow diagram of mat Figure 18 a-18e illustrates the master routine as the sensor processing unit 101 of carrying out all situations of the present invention.Different subroutines can be called to carry out indivedual aspect of the present invention by independent procedure.These subroutines are illustrated by the process flow diagram of Figure 18 f-m.Though these process flow diagrams are finished an operating system, but what can know is, if the user wants to use in being less than all situations of the present invention, especially, only want pressure data to be reached remote place as what accompanying drawing 17a-c discussed, then this formula can be done conspicuous correction.

For the purpose of the complexity that lowers process flow diagram, the above is used for the required a plurality of steps of single pressure value of calculation pressure sensor 51a-d and handles with single step in the step of this process flow diagram.Therefore, what can understand is, each step that needs sensor unit 101 to remove to read truck body pressure is that needs will be read according to following agreement from the voltage signal of each sensor 51a-d:

(1) sequentially reads each sensor 16 times.

(2) these 16 readings are average.

(3) will from the average reading of all the sensors on average with single average reading.

When truck started, sensor processing unit 101 was connected with the mains and each step of processing flow chart.At first preset the required numerical value of step 210.Sensor processing unit 101 moves to step 230 from step 210, reads out time and data from cpu clock 126 in this.Next step is a step 240, with printing machine 119 print off date, truck identity numbering, time and operator's numbering or by wireless set 150 reach the array VII with do back transmission with (the truck identity is numbered and is predisposed in the permanent storage).In fact, the data that output is done in all identifications all can reach the array VII so that these data are reached remote place, and this will be more apparent in explaining about the residue of appended each step of process flow diagram.Dedicated radio link transmits in conjunction with the accompanying drawings 19a-c and Figure 20 a-b and discusses in more detail.Operator's identity numbering is to obtain from keyboard 122 shown in step 250.In step 260, a counting is preset to the back sequencing of a maximum count with Control Software, and this can be in hereinafter giving more complete explanation.

When truck start and sensor processing unit 101 from step 210 to 260 pre-postpones, program just moves to the master routine circulation of step 269, in this, the distance of being noted down by range sensor 138 can be added to total distance of having calculated in the past, to upgrade total distance that truck is walked.From step 269, master routine calls one in step 270 and reads pressure subroutine (Figure 18 g) wherein, and this element reads out the pressure from pressure transducer 51a-d, and calculates a mean pressure in aforesaid mode.And, before and after this subroutine is also calculated and about pressure, use for other subroutines, this can be in hereinafter explaining.

In the step 275, program is numbered comparison with storage operation person's numbering with the current operator who imports from keyboard 122.If numbering is different, just this new operator numbering can be stored, and program can be in the step 277 call operation person transportation parameter that subroutine measured when analyzing the operation at the truck 11 of control in the past of making a summary.The operator make a summary subroutine will be in conjunction with the accompanying drawings 18h and discussing in more detail.If in operator's change that subroutine is performed back or operator numbering of making a summary is not take place in step 275, program just moves to step 280.

In the step 280, in order to obtain a net pressure value, in the mean pressure that the predetermined value of tare weight pressure can be calculated in step 270 and deducted.Because tare weight pressure is represented the weight of empty calorie car vehicle body, the load weight that on behalf of truck body 13, net pressure just carried.From step 280, sensor processing unit 101 moves to step 285(Figure 18 b), in this, whether decision net pressure value is less than zero.If net pressure is found to be minus words in step 285, program can be transferred to step 286.In the step 286, program net pressure and bucket pressure can be made zero (bucket pressure can make an explanation in the load analysis subroutine of the following drawings 18j).In the step 289, net pressure can be stored in first storage unit of array I, that is array I (1).16 up-to-date net pressure values can be stored in the array I.These 16 values can be in step 300 (Figure 18 b) by on average to obtain average net pressure of a time.

In the step 304, whether program meeting checked operation person start button 142(Figure 16) to indicate the calculating of axle load.If button is depressed, program can the independent procedure transfer be removed the axle load analysis subroutine of execution in step 305.The axle load analysis subroutine utilize the net pressure reading of truck body and from pressure transducer 139(Figure 16) net pressure go to determine the load of antero posterior axis, this is 18p and explaining in more detail in conjunction with the accompanying drawings.

With reference to the step 380 of Figure 18 c, sensor processing unit 101 determines whether a gear shift is detected by shelves sensor 135.If detected, program then goes to step 390.In the step 390, sensor processing unit 101 order printing machines 119 print off (or being present in the array VII):

(1) shelves before the truck gear shift.

(2) the up-to-date average net weight that calculates,

(3) time that is consumed in the former shelves.

(4) distance of being walked (range sensor 138 by Figure 16 obtains) with former shelves.

Though Figure 18 c does not show, a mark can be used for data are reached accompanying drawing 19 and 20 central computers of being discussed with the indication gear shift in step 390.If the shelves of truck are not converted in step 380, after perhaps printing machine 119 had been finished the function of printing in step 390, sensor processing unit 101 was in step 395, and whether the decision clock needs calibration (that is, go to or change from the summer time).

Need to proofread and correct as the time, program then is transferred to step 396, in this execution time sample just.From step 395 or 396, program moves to step 400, and determines whether dump sensor 137 is activated.Be not activated in step 400 if dump sensor, program then is transferred to step 405 and leaves step 304 and whether enter step 405 through 0.1 second certainly with decision.If because not through 0.1 second, step 405 meeting is with program flow returns step 380, so this delay gives, and this sensor processing unit 101 has the time enough window so that detect the startup of dumping sensor 137 in step 400 before further carrying out its program.If in step 405,0.1 second process, program then goes back to step 269(Figure 18 a).

As dump sensor 137 quilt decision startup in step 400, and program just is transferred to 406, and the subroutine of wherein tumbling is called to summarize the proper data of this haul-cycle time.In dumping subroutine, except discerning, calculate and printing the different parameters of single haul-cycle time, what can know is, collect and be in the array II, store some haul-cycle times by sensor processing unit 101, to provide such as transporting every day such as gross tonnage (GT), every day traffic load number of times, operator's sum every day or the average of date average load of being transported and average institute elapsed time of per haul-cycle time etc. individually from the data of vehicle-mounted weighing equipment and related sensor thereof.Accompanying drawing 18m will more completely explain and dump subroutine.From step 406, program is calculated net pressure in step 410.Shown in step 410, the single force value of gained is stored in one of RAM 107 and specifies and to be used for storage cart and to boost on one's body in the storage unit of power reading (that is, corresponding to the pressure reading of truck body top from vehicle-mounted weighing equipment).

For other partly provides one to dump the indication that has taken place to program, the mark of tumbling is scheduled step 420.This signal and gear variable signal and load signal (among the accompanying drawing 18j-k discussion being arranged) can reduce time duty cycle with control truck 11 to the distribution of shovel loader 160 for central computer provides enough information.The present invention can discuss in more detail in accompanying drawing 19a-b and Figure 20 a-b in this respect.

In the step 430 and 435, carry out one and calculate to upgrade the record amount of wheel service routine.In the step 430, (last computation is to begin to calculate when truck begins to load with the transportation range walked after the last computation.This will explain in the load analysis subroutine of accompanying drawing 18j-k) multiply each other with truck general assembly (TW) (that is measured tare adds the truck tare weight).In the step 435, from " ton mile " data of step 430 and in the past " ton mile " data addition.This gross ton mileage is according to the indication that provides the tire of truck 11 whether to wear and tear according to ton mile definite value.Because the authentic data of relevant tire wear there is no in others and provides, be expensive owing to replacing the worn-out tyres again, therefore, these data are very important for the operator that opens a mine.The duty cycle tare of every " section " all changes, the calculating that can carry out ton mile by sensor processing unit; Said " section " promptly be truck from load the place run to after dumping the place transportation terminal with at truck from dumping transportation initial point after the place runs to the loading point.The time of one period current duty cycle can be stored in the step 440.Elapsed time is meant that load is transported to the required time of destination (that is, dumped to now dump from last time).

By print out (or being stored in the array VII to do using of back transmission) current average net weight (being calculated) according to the startup of dumping sensor 137 in the subroutine of Figure 18 f in step 450, sensor processing unit 101 can provide the hard manifolding part of truck load immediately before dumping around hinge component 17 rotations at load mat vehicle body.The elapsed time of this duty cycle is also printed off.The current time reads in step 455.At last, if in step 460, determined present time than last time last whole hour of readout time in step 460 add one for big, 103 order printing machines 119 of CPU are noted down dump time in step 470.Do the execution of next step in order to preset step 460, step 475 is set present one whole hour and is equaled the preceding hour.

With reference to Figure 18 d, in order to reinitialize sensor processing unit 101 behind load dump, net pressure array (that is, array I) is that the vehicle body unlifting pressure that is calculated during with step 410 fills up its all 16 storage unit.With after the array I " filling ", sensor processing unit 101 is read the pressure of pressure transducer 51a-d according to same program described above in step 490 in step 480.In the step 500, pressure value is stored in one of them storage unit of array I, therefore, has replaced one of them and has been gone into vehicle body unlifting pressure in this array by " filling ".From 16 numerical value of array I, a mean pressure is calculated in step 510.

In the step 520, whether the mean pressure that sensor processing unit 101 decisions are calculated in step 510 adds a constant for big than the vehicle body unlifting pressure.This constant is used as an impact damper and is coupled with, and is placed down in before the routine processes next step on the pipe 47 to guarantee truck body 13.Because at first in step 520, the array I is loaded with the vehicle body unlifting pressure, (in step 490 and 500, obtain respectively and the reading stored except), the mean pressure of being calculated from the array I just approximates the vehicle body unlifting pressure greatly.Therefore, if in step 520, mean pressure adds a constant less than the vehicle body unlifting pressure, sensor processing unit 101 is just got back to step 490 through step 521, in step 490, obtain another pressure reading, and with the pressure that obtained in step 500 deposits the array I in.New value of every storage just loses a value the oldest in the array I.Whether recomputate mean pressure again according to the value in the array I, the value that is obtained adds a constant with the vehicle body unlifting pressure compares, transferred on the pipe 47 to determine truck body.Repeating step 490-520 reaches till add a constant than vehicle body unlifting pressure be big value (because decline of truck body) until the mean pressure that is calculated according to the array I.When this situation occurring, the sensor processing unit 101 just step 520 from process flow diagram forwards step 524 to.

Because the load of step 520 decision indication truck body is also not exclusively placed on the vehicle-mounted weighing equipment, whether step 521 inspection is moving before program flow returns step 490 to measure truck.The truck that mobile vehicle body rises can cause the badly damaged of hinge component 17 and hydraulic cylinder 19 and 21.If having measured truck from range sensor 138 in step 521 is to move, process flow diagram just is transferred to step 522 and 523, and wherein Hang Zou distance is noted down and upgraded, and status indication is set for step 524 and uses.

If the test of step 520 indication truck body is transferred fully, program is just left the circulation of step 490-523, and the status indication of step 523 is investigated in a test that is transferred to step 524.Set as mark, just truck is moved before vehicle body puts down fully.Therefore, go to step 525 and 526 in response to the set condition of status indication in step 524.In the step 525, what keeping one truck moves before vehicle body is transferred fully dumps sum.This status indication of step 526 replacement.

For check the transportation return situation (that is, not all load is dumped entirely), step 527 investigation serves as big from the pressure of vehicle-mounted weighing equipment to determine this pressure whether to add a predetermined critical than tare weight pressure, and in the embodiment example, this critical value is 7% of optimum load.Can come to a decision in the step 527, exist if mean pressure is excessive and transport the situation of returning, just can cause in step 528, printing off operator's numbering and lightening operator's numbering (or with data storage using in the array VII) on the display 117 for transmission with printing machine 119.From step 527 or 528, program moves to the step 530 of Figure 18 e, and there, CPU 103 reads present time and uses for next step.

Referring now to Figure 18 e, in the step 540, shelves sensor 135 can be reexamined, and looks at whether gear shift has taken place.If gear shift has taken place, program just is transferred to step 550, in this, utilize printing machine 119 print out the average net weight of shelves before following information (or transferring to the array VII) gear shift, latest computed, in the past shelves institute's elapsed time and before grade distance of being walked.The step 390 of image pattern 18c is the same, gear shift can be used as a status indication and is stored in the step 540, it being included in the data that transfer to central computer as mentioned below, in the step 560, whether sensor processing unit 101 is measured from the readout time of step 530 and is begun through 25 seconds.If not through 25 seconds, program then goes back to step 540, and unit 101 can reexamine whether have gear shift.25 seconds performed delay is to guarantee that truck body 13 has time enough can be placed on fully on the truck frame 15 before sensor processing unit 101 is proceeded to calculate in the step 560.

After 25 seconds, sensor processing unit 101 is to moving forward to step 570, in this, new net pressure reading calculated and each of 16 storage unit of the array I of packing in.According to 16 net pressure readings in the array I, in step 580, single average net pressure reading can be calculated.From step 580, the step 269 at the beginning of sensor processing unit 101 change-back procedure major cycles, this beginning is with " A " mark in process flow diagram.

The timer of one-period property ground generation (as: two seconds) interrupts making the step of subroutine among the sensor processing unit 101 execution graph 18f.This subroutine determines the rising of a current pressure to be owing to pulse (from rugged path situation) or to be the loading of bucket.If determined it is that the former causes pressure to increase, it is that a pulse is to monitor pavement behavior that subroutine should increase record; On the other hand, if determined it is that bucket loads, a series of step can be performed to upgrade the load condition of sensor processing unit 101.

With reference to the individual steps of Figure 18 f, the internal counter of CPU 103 is examined with decision whether reached the predetermined maximum count that sets in step 260 in step 582.This predetermined maximum count equals the unit number of array I, so that the consecutive mean force value of calculating in subroutine can be represented different pressure data groups fully.If the numerical value of counter surpasses the number of unit in the array I, program can go to step 584 from step 582, and wherein current net pressure can be examined to determine it whether more old net pressure reading adds a constant serving as big.This constant is a numeral, be intended to the identification pressure that mean pressure increased in the past recently, and this mean pressure is enough greatly to be used for whether being identified in later pressure increase because the pressure pulse due to the crankcase ventilaton situation.If the more old net pressure of current net pressure adds a constant for big, just program is at step 586 counter reset.Otherwise program just is transferred to step 616, and the function of this step will be in hereinafter discussing.After counter is set to zero, next interruption will make step 582 go to 588, rather than go to former step 584.

In the step 588, counter-increments, and in step 590, be examined to determine whether this counter reaches maximum count (equaling the number of array element in the array I).If counting is less than maximum count, not needing corresponding to nearest average reading in the past of array I is new reading entirely.Therefore, program just goes to step 616 and walks around the new on average calculating and the relative program of net pressure.

If current counting equals maximum count, program just moves to step 592, wherein the average net pressure from the array I can add a constant relatively with old average net pressure, calculate freely the hardware error of the equipment of A/D converter 129 (old average net pressure is average net pressure, this average net pressure be regarded as passing by recently a step 592 clean mean pressure when replying "Yes").Oldly on average adding a constant only as on average being no more than only now, must be a pulse just the pressure that causes counter to be reset in step 584 and 586 rises, rather than the indication of the weight of an increase bucket that continues to increase.Therefore, program can go to step 594, and wherein the size of array I is increased to 24, and corresponding maximum count just is increased to 24.By increasing the size of array I, more reading will comprise that each is average, thereby slow down the influence of pressure pulse.In order to monitor the rugged degree on road surface, pressure pulse is noted down in step 596.From step 596, program goes to step 616.In the step 616, by light-emitting diode display (light emitting diode indicator) 117(Fig. 2 b and 16) shown weight can be updated.On the other hand, except that this, new weight data can be reached the array VII, by dedicated radio link equipment weight data is reached remote place.

If the current average more old average net pressure of net pressure adds an error factor for big, a load continues to increase (that is a bucket lotus thing is added into) just can be instructed to so.Therefore, loading on step 598-608 has been updated.In the step 598, current average net pressure is converted into weight in order to making the usefulness of demonstration.Since truck be loaded (by adding bucket indicate), truck just can not be assumed that and to move; Therefore, pulse does not just resemble and can take place.Based on above hypothesis, the size of array I is reduced to 16 in step 600, so that more frequent average (maximum count also is set at 16) to be provided.In order to provide an old clean mean pressure and for its counting equals the old net pressure that the next one of maximum count interrupts, current average net pressure and current instant cleaning liquid pressure can be designated as old pressure in step 602 and 604.

Because truck 11 is in process of loading, a laod unbalance subroutine is called in step 606, and a load analysis subroutine then is called in step 608.These subroutines will be gone through in accompanying drawing 18i and 18j-k respectively, and from step 590,608,584,586 or 596, program can be updated in the average weight of expression on the display 117.Certainly, 598-608 has been bypassed as step, and this renewal average weight is then identical with old average weight.Carried out its each step when the program of Figure 18 f after, sensor processing unit 101 can be returned in the master routine of Figure 18 a-18e.

The subroutine shown in the process flow diagram of Figure 18 g-m of leafing through, every subroutine is invoked from the master routine of the process flow diagram representative of Figure 18 a-f.For Figure 18 g read the pressure subroutine, this subroutine is invoked from the step 270 of master routine.In the first step of this subroutine, be to obtain single mean pressure data on the vehicle-mounted weighing equipment in step 620 in foregoing mode.From step 620, subroutine is pressure before and after step 630 and 640 is calculated respectively.In order to calculate back pressure, average from the mean pressure reading quilt of back location sensor 51b and 51d.Correspondingly, for preceding pressure is provided, average from the pressure reading quilt of anterior locations sensor 51a and 51c.Pressure readings are used to be called and in the uneven subroutine that Figure 18 i represents in step 606 before and after these.

In the step 650 of reading the pressure subroutine and 660, the limit of the truck body of vehicle-mounted weighing equipment to limit pressure is determined.Particularly in step 650, understand by average, so that the pressure on first limit to be provided from the sensor 51a on truck 11 first limits and the mean pressure reading of 51b.Correspondingly, for the limit on its opposite, can be from the mean pressure reading of sensor 51c and 51d by average.As the front and back pressure reading, limit to limit pressure reading is used in the uneven subroutine of accompanying drawing 18i.When pressure transducer 51a-d is read out and after suitable pressure survey calculated, subroutine can be back to the step 275 of master routine.

With reference to the operator of Figure 18 h subroutine of making a summary.When the operation of truck is under individual operation person's numbering during Be Controlled, the data of expression operator operation can be collected and store, and after the operator adapts change with it summary and demonstration or printing.Though, the step of Figure 18 h is the description about organized data, and this organized data is numbered relevant with the operator, but what can know is, by the numbering of keyboard 122 inputs, list needs indication operator's change, and also will indicate the change of truck state under single operation person's control, for example, every day routine transportation, time of having a rest and other identification period etc.For example, the summary that forms according to Figure 18 h can be kept by the operator in the time in The whole control, but can be discerned as the identification shovel loader by sensor processing unit 101 by the additional numbers of keyboard 122 inputs, and summary also must be held for this reason.When truck points to a different shovel loader, the operator only need by keyboard 122 will be new shovel loader numbering input pickup processing unit 101, along with the change of this numbering, this unit output truck is contained in the characteristic of frontloader when loading and makes a summary.According to above, for knowing the people of the management of opening a mine, other natural stretching, extensions of Figure 18 h illustration notion will be conspicuous.

Under normal operation, the make a summary process flow diagram of subroutine of operator is set typical data, and these data can be stored during its normal running and summarized by vehicle-mounted weighing equipment.For example, because vehicle-mounted weighing equipment calculates the total load of per haul-cycle time, can be stored and accumulate for the loads of all haul-cycle times of an other truck operators numbering.From vehicle-mounted weighing equipment and the pressure reading of gross tonnage (GT) that mirror operation person transports, the useful information of operator's operation is indicated and just can be obtained by accumulation.

In order to write down the end that the former operator of truck numbers the time interval under the control, present time can be read out in step 669.In the step 670, the present time of step 669 or actual time reading be designated as " new operator's time ".For operator before finding out controls institute's elapsed time, the operator that can make a fresh start was deducted in the time old operator's time in step 671.In order to prepare next operator's change, the new operator that step 672 makes in the step 670 and discerned equals old operator's time the time.In the step 673, always transport tonnage by divided by bucket sum (this sum also is counted and accumulates) to provide the indication of every bucket average weight.To always transport tonnage divided by the load sum, average load weight is just found out from step 674.In addition, in the step 675, the pulse of being noted down in haul-cycle time sum by divided by the load sum so that the average pulse number of load to be provided, and this is an indication of the rugged degree of road.For the indication of tire wear is provided, this subroutine in step 676 by T.T. of being controlled from total " ton mile " number of step 435 and operator divided by the numerical value that per hour calculates " ton mile ".In order to show the averaging time of haul-cycle time, step 677 is divided by the load sum that T.T. that the operator controlled and operator are transported.In order to find out the distance that vehicle body that per duty cycle rises with truck is walked, the distance (from step 522) that step 678 rises total vehicle body is divided by with the number (step 525) of vehicle body rising load.Above data are stored in the array III of RAM 107.

In the step 680, the average of the bucket of every load is to be got by the information calculations of being accumulated in the haul-cycle time, that is, from the total load sum that reaches by the operator transported of the bucket of step 790.In the step 690, calculated the averaging time between bucket.Because the interpolation of every bucket is the program detection by Figure 18 f, the time between bucket just can be easily by decision (in the step 850) continuously.By time phase adduction is stored in it in array II, just can be calculated and be printed the averaging time between an operator bucket.This mean value can provide the indication of the problem that may take place in load cycle.In the step 700, the maximum duration spacing between the bucket of per haul-cycle time is added and betransported the sum in cycle divided by the numerical value indication that gives the average maximum spacing between operator's one bucket.At last, in step 710, the mean value that step 670-700 calculated is up to by printing machine 119, to give operator and employer thereof transport parameter more than one hard manifolding.Certainly, as former output data, these data can be transferred to the array VII and be reached central computer to wait for the radio link by being set up by vehicle-mounted transceiver 150.From step 710, this subroutine is back to the step 280 of master routine.

Referring now to Figure 18 i, the invoked uneven subroutine of the step 606 in the program of Figure 18 f, whether test and decision be uneven significantly by the load distribution that truck body 13 is carried.In the step 720, whether uneven subroutine test also determines up-to-date net pressure reading greater than 65% of predetermined maximum load pressure.If truck body 13 is not loaded into this percent of its capacity yet,, program is back to the step 608 of master routine among Figure 18 c just can withdrawing from this subroutine.When truck body is loaded to one during greater than 65% weight of maximum load, uneven subroutine just respectively in step 730 and 740 test limit to limit uneven and before uneven with the back.

In the step 730, limit to limit imbalance be by the pressure that decision optimum balance ratio (that is, 1.0) is multiplied by second limit deduct again first limit pressure gained result absolute value whether greater than as 10% truck load capacity and determined.If the imbalance of a load has been indicated in the test in the step 730, subroutine can start display 117, audio frequency output 196(Fig. 2 b in step 750) and/or printing machine 119(Figure 16) to warn the operator of truck.These data also can be transmitted by the array VII.According to step 750, program is uneven with the back before step 740 test.On the other hand, if limit to limit imbalance is not instructed to out in the test of step 730, subroutine just directly goes to step 740, in this, utilize just like the algorithm as the algorithm of step 730 with before testing with the back uneven (preceding with after best ratio can be-3 to+3).In in step 740, there is a front and back imbalance to be instructed to out, program then is transferred to step 760, wherein display 117, unbalanced signal 197(Fig. 2 b) and/or printing machine 119(or other as owing to remind the indication that is installed in lamp 197 on the truck etc. of loader operator) can be activated reminding operator's truck body to be loaded to unbalance condition, and this can cause damaging truck (these data also can be transmitted by the array VII).From uneven subroutine, program moves to the load analysis subroutine.

Referring now to Figure 18 j, the shovel loader that load analysis subroutine mat one uses bucket to load vehicle body provides and closes the data that the truck vehicle body loads.Relevantly increase the data of the bucket of load by analyzing and summarizing, just can obtain about the useful information of haul-cycle time efficient to truck body.In the step 592 of Figure 18 f, as determined the more old average net pressure of current mean value of the net pressure reading of array I to add a predetermined constant for big, the load analysis subroutine then is called from the program of Figure 18 f.As described in about accompanying drawing 18f,, can suppose safely that a bucket has been added on the truck body when more old average net pressure one constant of current mean value of the net pressure reading of array I when being big; Therefore, the load analysis subroutine can begin to be performed in step 770, wherein new bucket pressure be through now average net pressure deduct old average net pressure and calculated.

In the step 780, the calculating of the bucket pressure mean values of this load is the new bucket pressure that the number of bucket in the past with the average in the past bucket pressure of every load and load multiplies each other and adds in the step 770 to be calculated, gained and again by add by load bucket number in the past 1 and must every load bucket number removed and formed.In the step 790 and 800, subroutine is upgraded the bucket number of total bucket number and current haul-cycle time respectively.Among the step 810-815, the bucket time is noted down with in the relevant step that is ready for use on load analysis subroutine hereinafter described.

In the step 820 of load analysis subroutine, test to determine whether current bucket is first bucket of a haul-cycle time.If current bucket is first bucket of a haul-cycle time, program just goes to step 825-829 before the step 616 of master routine in being back to Figure 18 c, in order to be used for and bucket loading time and the relevant calculating of total bucket, step 825 will rename as " old bucket time " " new bucket time ", and presets array V and the VI of RAM 107.In order to be used for communicating by letter, there is a load mark to be set in the step 827 with the flowing of control card fleet with central computer.The data that this mark is used to transmit vehicle-mounted weighing equipment are to central computer, and this will explain in accompanying drawing 19-20 in more detail.At last, in step 828 and 829, will obtain new ton mile ratings, this ratings is corresponding with the ton mile ratings from the transportation section of dumping place to the loading point time.

If current bucket is not first bucket of a haul-cycle time, program can go to step 830-860 from step 820.In the step 830, the time of institute's warp can be calculated in step 830 between the interpolation time of the current bucket that is situated between and the interpolation time of former bucket.In the step 840, the bucket time can be updated to prepare the data of next bucket.In the step 850, between current bucket with before between the time meeting of bucket institute warp and bucket total walking time of each time interval provided total institute of loading through the time mutually.This is total load be used to the operator through the time and make a summary in the step 690 of master routine, so that the designation data of truck and operator's performance to be provided.

In order to store the net pressure of every bucket, step 852 is stored into the pressure data of all buckets of current duty cycle in the array V.Last location N in the array V is used as the storage unit of the average bucket gravimetric value of a load.Aspect the storage of these pressure, the time of institute's warp was in the array VI between bucket attached in one duty cycle of step 855 storage.The data of array V and VI can be used to provide the detail operations report of per duty cycle.

Among the step 860-885, the time of the longest institute warp is found out between bucket.In the step 860, sequence test also determines whether second bucket of current bucket.As current bucket is second bucket, and program is automatically specified the time of institute's warp between current bucket in step 870 be the time of the longest institute warp between bucket.On the other hand, as having determined that in step 820 and 860 current bucket is not first or second bucket, program will go to step 880, and wherein the time of the longest institute warp is length between the bucket that whether time of current institute warp can be tested and determine to be noted down than before between bucket.Be not more than time of the longest institute warp between former bucket as time of current institute warp between bucket, program just goes to step 890(Figure 18 k); Otherwise it is the time of the longest institute warp between new bucket that program is specified the time of institute's warp between this bucket in step 885.This is the longest to be used to the operator through the time and to make a summary in the step 700 of subroutine.

Referring now to Figure 18 k, current average net pressure tested with the load of indication truck whether sufficiently approach can because of a full bucket the material of interpolation again, and cause the maximum load capability of truck body g-load.In order to prevent the truck g-load, whether the residue capacity of step 890-920 test and decision truck body 13 is less than the weight of an average bucket of being calculated in the step 780 of subroutine.

Particularly in step 890, average net pressure deducts 1/4th of average bucket with the predetermined maximum load of truck body and compares.As average net pressure than this maximum load deduct average bucket 1/4th for big, truck body will be because of adding as filling few material g-load as four fens buckets.Therefore, subroutine goes to step 895, and wherein the red light 140e of load indicator board is activated.Red light 140e is as the warning loader operator, and truck body 13 is loaded to the capacity that any loading all can make the truck body g-load.

Do not subtract four minutes one of average bucket value for big than maximum load as average net pressure, subroutine will move to step 900, and wherein current average net pressure can deduct two minutes of average bucket value with predetermined maximum load and compare.If determined current average net pressure to deduct 1/2nd average buckets for big than maximum load, subroutine just goes to step 905, and wherein four minutes one amber light 140d of the thermote 140 of Figure 16 can be activated.For loader operator, amber light 140d indication shovel loader can further attach material to truck body 13 in four minutes one, but its amount is less than 1/4th of shovel loader grab bucket capacity.

Determined average net pressure not deduct two fens average buckets for big than maximum load as the test in step 900, whether subroutine deducts 3/4ths average bucket values for big than maximum load in step 910 test and the current average net pressure of decision so.For just, subroutine then goes to step 915 as the value that determined in step 910, and wherein two minutes one amber light 140c on thermote 140 can be activated.As the method for four minutes one amber light 140d, two minutes one amber light 140c indication loader operator, the material of next bucket must load with two minutes one capacity that are not more than bucket, to avoid the g-load of truck 13.

For negative, subroutine is then tested and is determined whether predetermined maximum load deducts a fully loaded average bucket for big to current average net pressure as the test in the step 910.For just, subroutine is four of starting load indicator 140 minutes three amber light 140b in step 925 then as the test in step 920.For negative, the green light of thermote 140 can be activated with the indication loader operator as the test in the step 920, and the material of a full bucket load can be added in the truck body 13 and can not cause the vehicle body g-load.From step 890-926, when the loading of truck body 13, the wherein lamp 140a-e on the thermote 140 can start often.

The narration Figure 16 that digresses from the subject tout court, the lamp 140a-e of thermote 140 install with overlapping arrangement, and like this, their relative position just provides the indication of truck capacity residue degree.Particularly, green light 140a has accounted for extreme lower position in this folded lamp 140a-e, thereby the indication truck body has and can expire the capacity that bucket loads for one.Red light 140e takies the position, top of this folded lamp, and the indication truck body is fully loaded, and can not add more bucket load safely.Three lamp 140b-d are placed between green light and the red light, with indication between with the full grab bucket capacity of green light 140a symbolic representation with the load-carrying capacity between the no residue capacity of red light 140e symbolic representation.

Referring now to Figure 18 l, when the step 304 of master routine had determined the operator need call axle load to analyze, the step 305 that the axle load analysis subroutine just can independent procedure was called.As the explanation of accompanying drawing 13a and the appended explanation of 13b, the pressure that promotes cylinder barrel 19 and 21 need be used to calculate the load distribution between antero posterior axis.Thus, in step 928, from sensor 139(Figure 16) pressure can be read and convert to a weight measurement by CPU 103.In order to obtain total tare, the load weight of deriving by current mean pressure can with the truck body tare weight addition of step 929.In the step 930, the center of gravity of load can be calculated from the weight measurement of sensor 139 in gross weight and lift cylinder cartridge system.In the step 930, being used for the special algorithm of position of computational load center of gravity is to be listed as Figure 13 a and the appended equation of 13b (2).Known load center of gravity has been arranged, utilized equation (4) and (6), the load distribution on the antero posterior axis is just respectively at being determined in step 940 and 950.

In the step 960, the tare weight of antero posterior axis can with the axle load addition of the antero posterior axis of being calculated in step 940 and 950.Therefore, should reflect the general assembly (TW) on the antero posterior axis by the antero posterior axis correction pressure reading that step 960 obtained.At last, in step 980, subroutine order printing machine 119 is printed heavy burden on the antero posterior axis (or be stored in array VII it).

Figure 18 m that now leaies through, in master routine step 400, detected dump sensor and be activated after, dump subroutine and be called by the step 406 of master routine.At the end of a haul-cycle time, to dump subroutine and summarize selecteed parameter, the end of haul-cycle time is that the startup that mat dumps sensor 137 is indicated.In the step 1000, control down gross tonnage (GT) by truck transport and be used to the operator and make a summary in the subroutine to be provided at the operator on the hauled weight sum before current average nt wt net weight is added to.Indicated a termination owing to dump the startup of sensor 137 to the haul-cycle time, the average bucket pressure of the bucket number of every load and every load is set to equal zero in step 1010 and uses for following one-period to preset these numerical value.In the step 1020, between bucket the time of the longest total institute warp be through and the bucket of a last duty cycle between the longest institute warp the time addition and be updated.

In order to note down the haul-cycle time number, step 1030 has increased progressively the storage number that is identified as " load sum ", and this load sum is used for the operator's average data indication of subroutine the operator to be provided to operate of making a summary.For the rugged degree of monitor road, the pulse sum of being noted down in the haul-cycle time is accumulated with the umber of pulse of haul-cycle time in the past in step 1040.The pulse sum is used to the operator and makes a summary in the subroutine so that the indication of road quality to be provided.After step 1040, umber of pulse is set to zero, so that provide a new benchmark for the pile-up pulse number in next duty cycle.

In the step 1050, whether a test is performed to determine current average net pressure greater than a predetermined maximum pressure corresponding to truck maximum load capacity.As the test in the step 1050 just is, the g-load of truck is then noted down in step 1060-1080.In the step 1060, it is a g-load cycle that a g-load counter is incremented to indicate the current haul-cycle time.In the step 1070, to be mat deduct average net pressure mutually and calculated from maximum allowable pressure for g-load quantity or " g-load pressure ".The g-load pressure of current haul-cycle time is added in total g-load pressure of all haul-cycle times, force value with general assembly (TW) that an indication truck g-load is provided, from step 1080 or according to 1050 negative indication, dump subroutine and move to step 1090, wherein printing machine 119(Figure 16) be activated time (being stored in the array VII) with institute's warp between every bucket weight (being stored in the array V) of beating brush haul-cycle time of just having finished and every bucket.These data also can reach the array VII for transmission.

Be may be obvious that by above description, mass data is from vehicle-mounted weighing equipment and relevant being collected at onboard sensor thereof.When many trucies of a fleet are equipped with when collecting these data, can give the operator of fleet the interests of maximum in order to make these data, these data need to be passed and carry as longer-term storage and analysis, to produce and to keep the historic archives of truck caravan's activity and performance.Significantly, printing machine 119 provides a nonvolatil record.Yet for big fleet, even store data with this mode under best-case, in the hope of being made for than post analysis and reference, this is still trouble.Therefore, the data that produce in order to make more easily are operated and analyze, and sensor processing unit 101 can be mixed the storer such as magnetic tape cassette or non-volatile memory component etc., and it is defeated to be poised for battle biographies when reaching their capacity at array.Yet transmitting with this mode is not based on the real time, and to need operator or management to get involved with the data of guaranteeing to be transmitted be to collect (that is, the collection of paper tape) in good time mode.

For the data that sensor processing unit 101 is produced have maximum benefit and value, this just needs to collect and analyze (this with just collect paper tape when the work period finishes be different) therefore according to the real time, when data were produced by one group of truck, it can be collected so that the real time analysis of one group of car operation to be provided at once.Therefore, according to preferable embodiment of the present invention, if the real time data of accumulation are that the mat radio link transmits from the remote fixed position of vehicle-mounted weighing equipment to, and be equipped with historic real time archives at this remote fixed bit and produced and analyze, indication now with managerial personnel's one truck team performance of giving in remote place, like this, the real time data of this accumulation are just extremely valuable.By analyzing by the data of unloading on historic real time basis, the shovel loader of truck also can be evaluated.As a characteristic of the real time data of collecting with the radio link transmission data, each trucks entering links to each other with one or more relay station in the fleet radio link and central computer communication.When this situation occurred, these relay stations also can transmit data from central computer and return other truck.Therefore, instruction/indication just optionally is sent on the truck.

With reference to Figure 19 a, in operation or the of this type transportation of opening a mine, often there are table soil, coal or similar material side by side to betransported.And, in a large amount of operations, have the shovel loaders 160 of crossing one more and be engaged in, and have the more than one place of dumping for the truck team uniform.When the operation of opening a mine was huge and a lot of trucies and shovel loader are arranged, data that collecting sensor processing unit 101 is produced and control just seemed un-skill from dumping place to 160 round traffic flows of shovel loader, thereby seem inefficent.A kind of function as the data collection capability of vehicle-mounted Weighing system, allow that at vehicle-mounted weighing system the electronic system of Figure 16 notes down the time of a haul-cycle time or its each Duan Suojing exactly described in the literary composition, and, when a duty cycle begins and terminates, vehicle-mounted Weighing system provides an indication to this electronic system, and this is installed in every truck 11(Figure 19 a as a wireless set 150 and illustrates) go up data are reached the central computer 155.After these data are by central computer 155 Collection and analysis, can be used to provide the instruction and the indication of efficient traffic control and telemonitor truck performance by central computer.Moreover, such as in the process flow diagram of Figure 18 a-m general introduction, also reach central computer 155 from other data of vehicle-mounted weighing equipment and be made for storage and analyze.The data transmission communication that truck 11 and central computer are 155 is that this will do more detailed narration hereinafter by the strategic position repeater 160a of Figure 19 a and 161 manipulations.

Central computer 155 by radio (or rigid line) link 157(or fixing certainly reception place such as the hard-wired link of dumping the place) receive data from electronic circuit on the truck 11.For a two-way link is provided, central computer 155 includes a receiver 155a.The data that receive from truck 11 are to handle through the CPU 155b that has PROM 155c and RAM 155d to help.CPU 155b communicates by letter with PROM 155c and RAM 155d along bus 155e in a conventional manner.

Because when vehicle-mounted weighing equipment and interlock circuit thereof is beginning (first bucket is detected) and the termination (gear shift first time behind first bucket) of a duty cycle and when is the beginning (and other service datas) of dumping if determining, central computer 155 just can utilize these data that effective instruction and indication moving with the control truck are provided under the situation that does not rely on anyone worker's assistance, for example, anyone need not remember with staff by load or dump key to signal to central computer.Because this system is a full automation, thereby height reliability arranged, moreover collect data in real time Radio Data-transmission mode from vehicle-mounted weighing equipment, when it by central computer stores and when analyzing, just can really control the stroke of truck to reach top efficiency by Quasi.

With reference to Figure 19 b, trucks entering the wireless set 150 and Frame of transmission contains a synchronization character has the data of truck numbering and representative such as truck states such as load or dump state behind synchronization character.The data that received of response from truck 11, central computer stores and analyze this data.After central computer was suitably analyzed these data, central computer can be selected the Frame that contains a synchronization character according to the truck state, and specific truck and shovel loader numbering is arranged behind this synchronization character.In order to prevent from the truck 11 time or overlapping transmission, truck 11 transmits with the interrogating signal of response from central computer 155.Whether central computer 155 poll trucies 11 have any truck to prepare to transmit data with decision.In response to poll, truck 11 transmits required data (dump, load or other data) with the form shown in Figure 19 b.

According to the detection that produces such as data such as dump state (startup of tilt switch 137), load condition (detection of first bucket) and similar states, automatic switch radio transmitter 150 just can take place with the transmission of carrying out Frame.Significantly, whether Frame comprises load or dumps data indications to be whether to be activated or whether first bucket is added and decides according to tilt switch 137.Central computer 155 receives from truck 11 and the data represented in the Frame mode, and reach a conclusion by these data, to infer that shovel loader 160 can be one and terminates because of dumping now that the truck of duty cycle provides the fastest time duty cycle before it, perhaps, for loading a now thereby being ready to wait to instruct and/or indicate the truck that dumps the place that the one suitable place of dumping is provided, this will explain in more detail in accompanying drawing 20a-b.Central authorities calculate meter 155 once determined which shovel loader can make time duty cycle reduce to the shortest or which dump the place suitable after, this computing machine just comes transmit data frames by wireless set 155a, and this Frame contains indivedual trucies numberings that this computing machine will address and this computing machine will indicate the loading of truck or dump the place and number.Each truck all receives the Frame from central computer 155, is that the truck identical with the numbering that is transmitted can react with these data that contain the shovel loader numbering but have only its numbering that has.When the truck numbering is numbered data consistent with truck, shovel loader dumps the place of specifying numbering or other and truck numbering to transmit in the lump in the place and specifies numbering just to be displayed on the light-emitting diode display 117 of specifying truck, perhaps is printed as hard manifolding part on the printing machine 119 of this truck.According to the shovel loader numbering, truck operators is just known the shovel loader that will go when doing next load.Similarly, when a plurality of places of dumping when being used, central computer 155 also can transmit specific data, or is scheduled the indication that transmits a resting place when doing rest the operator.For being familiar with the people of the work of opening a mine, much other useful appointments are as can be known.

Briefly with reference to Figure 19 c, an opening 1300 can be arranged on the base plate of vehicle body 13 allowing that a switch module detects existing of a load, and indication sensor processing unit 101 when loading beginning by this.This equipment can with sensor processing unit 101 combination to provide a simplification truck transmitting system that forms according to Figure 19 a.Extra switch assembly among Figure 19 c has been arranged, for only with load and the truck that sends simply that dumps that signal reacts just do not need vehicle-mounted weighing equipment and auxiliary load cell thereof (dump sensor except).

Opening 1300 on the base plate of truck body 13 is by being covered such as soft but coarse material 1301 such as thick rubber gasket, and this material is peripheral and be fixed on the truck bed along truck.One hinge plate, 1302 mat springs with the assembly 1303 of axle upwards partially.React along with in the truck body 13 introduction of material being arranged, hinge plate 1302 is shut on opening 1300, and pushes the piston of switch 1304.Certainly, this switch cuts out sensor processing unit 101 is produced the signal that an indicating device begins.

In the process flow diagram of Figure 20 a, the processed and storage of the data that received from truck 11 is finished the truck of haul-cycle time to determine a correct shovel loader to send order exactly to one.The look-at-me of one-period property makes the step of central computer execution graph 20a.During each interrupts, the data of all trucies 11 of central computer 155 polls.In the step 1097, present time is read out and storage temporarily.In the step 1098, the truck numbering is preset value at the beginning.By automatic keying, and a formative interrogating signal is sent to the truck of appointment to wireless set 155a in step 1099.Detected in step 1100 as data, computing machine is then read and deal with data according to step 1110-1190; Otherwise the truck numbering is understood by increment in step 1102, and new truck polled data in step 1099.Because this interruption is all polled, step 1104 just goes back to master routine with central computer 155 as all trucies.After an effective transmission was detected, process flow diagram moved to step 1110, and in this, the truck numbering is decoded.Comprise as the Frame that is received and to dump indication, just the nearest load time of this specific truck is deducted during time from now in step 1140.So that a load haulage time to be provided.As dump not appearance of indication, and program just goes to step 1132, and in this, whether Frame is tested has a load to indicate.Contain load indication as Frame, program then goes to step 1135 from step 1132, and wherein, the real time can be stored as " load time ".Do not occur as load indication, step 1132 can go back to master routine with central computer 155.Similarly, other data that are transmitted (change of gear shift, operator's numbering etc.) can be discerned and be directed on the suitable storage cell of central computer by central computer 155.Certainly, data of different types (as, the time of institute's warp, the weight of bucket etc.) must mat sensor processing unit 101 encode in a conventional manner, so that central computer 155 can be discerned these data to classify.

In the central computer 155, there is a database (not showing) to be retained and uses for each truck and every type truck.For example, in the fleet of one 20 trucies, truck 1 to 10 can be the first type truck with a specified vol, and truck 11-20 can be the second type truck with a different capabilities.According to the composition of this truck team, a database is formed so that Useful Information to be provided best.For the fleet of above-mentioned one 20 trucies, database is divided into two major parts, and each uses for each type truck, and every part has 10 unit, and each unit uses for each truck.Use the database that upper type is formed, the data of every truck just can be collected and handle, and the data of each type truck also can obtain.Moreover because each haul-cycle time of truck can be discerned by specific shovel loader, the database of every truck/dump place/shovel loader combination also can be set.

In the database of central computer 155, the unit of every truck contains recognition data, with identification directed last shovel loader and its directed time of truck.Therefore, being transported to a specific average load haulage time of dumping the place once specific truck from a specific shovel loader can be determined, in the step 1150, be stored in each truck among the RAM 155d dump the average haulage time of spending in the place from each shovel loader to each can be by access.In the step 1160, one holds and decides truck and be added in this mean value from a specific shovel loader and a specific nearest haulage time of dumping the place, to upgrade this mean value.The average load haulage time of this renewal is sent back in the storage array in step 1170.

Because central computer 155 is to communicate by letter with each truck 11, central computer is known the number of the truck 11 of delivering to specific shovel loader; This computing machine also knows that the truck what have deliver to specific shovel loader 160 has been instructed to begin load.According to above information, from dumping the place or other areas become and can supply the time spent, central computer 155 is just carried out an algorithm in step 1180 as truck, dumps the place to determine that shovel loader can full out load the truck of now and it is sent back to." delay " time and identification that central computer 155 calculates every shovel loader have the indication of the shovel loader of minimum delay as truck.The delay of every shovel loader 160 can be by following decision:

Truck number * the shovel loader (n) that postpones (n)=in transfer or at shovel loader (n), locate average

Load time-from the load transmission in nearest past and between the average load time

Institute is poor through the time

According to above algorithm, central computer 155 calculates in conversion according to the data that provided or in a conventional manner at the truck number of shovel loader (n).Because central computer 155 has been discerned the known shovel loader 160 of those trucies directed one and has not been transmitted a load commencing signal yet, in the shovel loader place or the calculating of the truck number in transfer can easily derive from the data that be provided.The load time of every shovel loader is that the data that the sensor processing unit 101 of mat truck is provided are calculated.When central computing machine 155 received load signal from sensor processing unit 101, it just noted down the beginning of load.After the load commencing signal transfers to central computer 155, when central computing machine 155 receives from shelves sensor 135 and during first shift signal that mat sensor processing unit 101 detects, the termination of this loading is just marked by central computer 155.Significantly, for the average load time that central computer 155 calculates a load time and every shovel loader, vehicle-mounted weighing equipment must transmit the load commencing signal and indicate the signal of first gear shift.Indicating the signal of first gear shift not narrate in process flow diagram, is that these data can be transmitted according to the polling request from central computer 155 but the programmer can know.

Owing to load is order (that is every truck 11 alternatelies are by fully loaded); So have only final load transmission signals truck that still is loaded from the beginning.Therefore, surpassing more than one load transmission signals, to indicate some truck be to dump in the way, place sending to return.Obviously, when calculating the time delay of loading, needn't consider these trucies.In order to calculate exactly by the time delay that truck caused that is loaded now, the time that final load signal and average load time are differed should be from being transferred to or being multiplied by the product of average load time gained at the truck number of shovel loader part and being deducted.This differs the result and is added to truck on the travel time that the directed specific shovel loader 160 in its present place (be generally and dump the place) is spent.For example, before considering the truck travel time, two shovel loaders can have the delay of 5 minutes and 10 minutes respectively.Yet, if walk to the travel time of first shovel loader 160 be 12 minutes and the travel time that runs to second shovel loader is 5 minutes, this travel time is deducted the total delay time to reach from time delay, this is-7 minutes for first shovel loader, and for second shovel loader be+5 minutes; Therefore, will wait the truck time because be the expression shovel loader negative time delay, it is the target of truck that central computer 155 is just indicated first shovel loader.After the delay of every shovel loader 160 was calculated, central computer 155 transmitted a signal in step 1190, and this signal has the data of discerning the specific truck that will be transmitted; And this signal also has the current data with specific shovel loader numbering of minimum delay time of indication.

According to the transmission from central computer 155, the wireless set 150 of all trucies 11 is pinned this signal on the synchronous part of transmission, and the truck numbering that is transmitted is compared with the numbering of truck itself.Shown in Figure 20 b is to carry out the process flow diagram that the truck that is transmitted is numbered the comparison of numbering with stored truck.In simple process flow figure, the step of Figure 20 b is by counting interruption for the moment and periodically being performed.During each interrupted, the CPU 103 of Figure 16 checked whether wireless set 150 is receiving a transmission.As there not being signal to occur in the step 1210, program can go back to master routine with CPU 130; Occur if any signal, the truck signal that is transmitted can be captured and compare in step 1220 and truck body numbering.Inconsistent as two numberings, just after the truck that is transmitted numbering and discern specific shovel loader and number, dump the data of place or appointed place and can be omitted.Consistent as two trucies numberings, 155 of central computers contact with specific truck 11, and inquire about or instruct shovel loader 160 that this truck will go, dump place 161 or appointed place.Know that in order to make sensor processing unit 101 current what received is that a kind of indication.Data after the step 1225 decision truck numbering are polling request.If these data are polling request, whether program then contains the data that will be transmitted in step 1240 decision array VII; If contain, 150 of wireless set are by automatic keying, and suitable data (for example: dump, the change of load shift, operator's numbering etc.) then are transferred into central computer 155 in step 1250.On the other hand, not polling request as the data that received, it must be shovel loader, dump the indication of place or other destinations.Therefore, shovel loader numbering, dump place or other and be instructed in and be stored in the step 1260 and show to truck operators.

In the haul-cycle time, two important walking section one shovel loaders are arranged to dumping the place section and dumping the place to the shovel loader section.These two sections is holocyclic main part.Because when vehicle-mounted weighing equipment detects is beginning of loading and when is the generation of dumping, when truck 11 was polled, significant data can be transferred to central computer 155 from truck 11 in this time, handles.For example, because ton mile has been represented the service routine of tire in the transportation section, so the ton that mat sensor processing unit 101 is calculated mile is important to every transportation Duan Eryan.According to the poll of truck, data can be transferred into CPU (central processing unit) 155 and handle.Managerial personnel can monitor (on the other hand in the place of central computer 155, central computer 155 can comprise software program to monitor these data or other data) from the renewal or the average ton mileage certificate of every transportation section, and complying with the mode of guaranteeing to have uniform fleet ton mile cumulative number and/or tire not to be higher than the per hour ton mile ratings of its quota and being used and send truck.Certainly, other data of supplying from weighing equipment on the car are that same way as the available as above data reaches central computer 155.At last, a part of data that reach central computer 155 are more reached on the processor onboard (not showing) of the shovel loader 160 that loads truck, to give the indication of a truck load condition of loader operator.Such communication link can be the link that is similar to above-mentioned relevant central computer 155, the radio link of this specific type can be any being fit to make the commercially available data link that the data mode transmits, and comprises the RDS-1200 type 944-960MHz full duplex radio modem of making such as REPCO company here.By what above can know is that data such as the operator of array II summary will be reached central computer by the storer of sensor processing unit 101 for storage and analyze.

In order to lower on every truck 11 expense of device high power wireless set, the distributed locations in the work place is provided with among fixed relay station 160a and the 161(Figure 19 a) be made for the usefulness of data transmission.Relay station 160a and 161 have been arranged, and 150 need of every wireless set are low-power equipment.Moreover through well-known method in the communications field, central computer 155 can identify those repeaters 160a and 161 and transmit the truck data of being transmitted again.Through known to given trunk station 160a and 161(wherein truck 11 be in communication context), central computer 155 can be followed the tracks of moving of truck.Moreover, transmitting and during the poll truck at data mat central computer 155, the indication truck is also can be transmitted at " stopping using " state or in the data of " in the transfer " state.Had such as above data, central computer 155 just can continue to follow the tracks of those current load, dump, transfer in or the withdraw from service truck.When truck 11 directed different shovel loaders 160, when dumping place such as place, the schedule time that central computer 155 points out truck to arrive according to its historical data archives.As truck 11 add between can not be at this moment this time one predetermined percentile during in arrive the appointed place, central computer 155 will to managerial personnel provide a sensitivity vigilant signal so that the state of truck can be examined.For those withdraw from service trucies 11, central computer 155 is renewable wait to repair truck the load delay of appointed specific shovel loader 160.

As the above extension that is used for transmitting and control the data that truck moves, the sensor processing unit 101 of truck 11 and the interaction of central computer 155 also provide the ability at remote place management data archives.Particularly, reached in the master data archives relevant with central computer 155 from the information of each sensor unit 101, these data can be handled by principal computer 155 and provide the real time information of usefulness to managerial personnel.For example, according to the real time data, central computer 155 can be analyzed load average number or the tonnage that is per hour loaded by specific shovel loader 160, and/or analyzes load average number or tonnage that specific truck transports.According to above analysis, the accurate plan of optimum utilization truck and shovel loader just may formulate out.

Send to suitable shovel loader 160 except the data of reception transmission and with truck 11, dump outside the place of place or appointment, central computer 155 also keeps the data that specific shovel loader loads tonnage, specific truck transport tonnage and is transported to the gross tonnage (GT) that whenever dumps the area.Central computer 155 is noted down the time of stopping using of all trucies 11 and shovel loader 160, and discerns those and stop using the longest truck and shovel loader of time in a schedule time.

The management of opening a mine had this system just can see to produce done during the ore deposit a little what, and can make 1 month, 6 months in the future even might be 12 months extremely accurately plan.Had these about for example the plan of the output of always opening a mine such as expectation tonnage of the different materials that will be moved, the operator that opens a mine just can make the distribution of equipment, and change the distribution of these equipment so that produce the ore deposit amount can be in fact meeting the ore deposit plan of producing.

For example, central computer 155 cumulative bad ground in a known time frame is per hour noted down, ton-mile data, so that per hour resembling the accumulation word of truck accumulation ton-mileage etc., can compare mutually by all trucies, and per hour exceeding, the truck of ton mileage can be sent to the place that those less per hour ton-mileage occurs.

Moreover central computer 155 and sensor processing unit 101 can be analyzed the strain of the vehicle assemblies such as heat that produce in temperature such as engine working temperature, hydraulic oil, the tire.When the specific components on the vehicle reaches a preset limit, this vehicle just may be sent to the less transportation of a pair of vehicle test in transportation in the future sends, that is, for a mining site with a plurality of working linings, vehicle can be by the wheel stream translation, so that leave from lowermost layer continuously to not having a vehicle.The analysis of this vehicle assembly strain has been opened significantly and will have been added the additional vehicle monitor to this vehicle and the RTTY Movement Capabilities to central computer from these monitors is provided.

Conceptive, the master data archives of central computer 155 (do not illustrate, contain four basic archives from the transmission data:

(1) each part charging appliance is to the loading time of each truck.

(2) each truck extremely respectively dumps the load haulage time in area from each shovel loader.

(3) each truck is from respectively dumping the unloaded time of return of area to each shovel loader.

(4) each truck extremely respectively dumps total haulage time in area from each shovel loader.

These master data archives can separate or merge mutually with it with the database of the truck (every truck has sub-archives) of each type and every shovel loader/dump place combination.

Each archives of four basic archives of master data archives are whether manufacturing, model, size, the type of mat such as vehicle body or the material type of being transported are charging appliance type, the truck type of ore in sand form, table soil, dual purpose etc. and dump the place and separated.For example, 170 tons of trucies separate with the data of 120 tons of trucies.Every class truck, load machine and the combination of dumping the place all have independent historic archives, with deciding such truck to go to the loading point or load the place certainly and go to and dump the required time of place from dumping the place.With regard to shovel loader 160, all there is a similar sub-archives economy in every class.Moreover the various truck that shovel loader 160 loads it all has sub-archives.This a little archives storage shovel loader 160 loads the historical data of any 11 time spents of ad hoc type truck.

A specific example as database and master data archives, have 10 170 tons of Wa Buke trucies and 10 120 tons of Euclid trucies as a mining site, then the database that had of central computer 155 will comprise every truck, shovel loader/dump the historical temper archives of place combination, that is 20 sub-archives of truck.From the data of 10 Wa Buke archives by together on average to form a main Wa Buke data archival; Similarly, main Euclid data archival is set up for the Euclid truck.So when relevant truck produced data, its corresponding historical temper archives were updated according to these data and on average.According to the transmission data of the historical temper archives that are used for upgrading every truck, four basic archives of the master data archives of every class truck (for example, Euclid truck or Wa Buke truck) also are updated.

By the degree of the data that vehicle-mounted weighing equipment provided and change as can be known, the transport communication link between truck 11 and central computer 155 may be a lot of in the rf data transmission link, and the rf data link also is traffic control person's equipment.With all of sensor processing unit 101 generations or the data transmission of partly selecting, make central computer 155 bring into play the Functions of Management System of opening a mine.The function of this system of the following stated is intended to the general introduction as program step, this program step can make it can be incorporated in the database by the storage mechanism in the central computer 155, this database has the sub-archives of each truck described in the literary composition/shovel loader combination and the basic archives of every class truck, and remove last relevant accompanying drawing 19a-b and 20a-b in load mentioned above and dump the transmission data.

For the poll of doing by central computer can take place so that the transmission of data can reach the real time data and reads fully often, the relay station 161 of enough numbers should be arranged on important position.Moreover by identification card car position in repeating signal, relay station 160a and 161 has just discerned the position of truck, that is when the data-signal from truck 11 was received by relay station, this data-signal was replenished the data with the identification relay station.When accumulating in data each sensor processing unit 101 at truck 11, these data are stored in the storer, and when truck was in the scope of relay station 160a or 161, the data on storer were reached this relay station and deliver to central computer 155.The relay station 161 that is positioned at primary location has been arranged, not only data can near actual time the base be transmitted, and relay station can keep the accurate supervision of a truck position.

For example, dump regionally 1 the time when truck 11 leaves, 155 of central computers are by notifying that shovel loader 160 of this truck to have the shortest delay at the relay station 161 that dumps area 1.So truck 11 examples are set out to this specific shovel loader position.Truck 11 in this route is can be with some data accumulation to the distance of this specific shovel loader 160a.When this truck arrives in the scope of this specific shovel loader 160a, if on the way from former not being transmitted of data of dumping regional I accumulation, these data can reach the relay station 160a of shovel loader and deliver to central computer 155 again, thereby the now of having discerned truck is approaching.

When central computing machine 155 detects transmission data from truck by the locational relay station 160a of the shovel loader that truck was sent to, this computing machine just know at once truck arrived this specific shovel loader near.As truck (can be Figure 19 a dump area 2) in going to another shovel loader 160 of passage in transit of specifying shovel loader or arriving the scope of another shovel loader that is in important place 161, the data of any accumulation just are transferred to central computer 155 by this relay station 161, therefore discern the position of truck once more.

As long as truck 11 1 arrives the shovel loader 160 or the loading site of appointment, the driver just can be placed on variator neutral gear or reverse gear.Gear shift is detected by the shelves sensor 135 of vehicle-mounted weighing equipment, and data then are transferred to central computer 155 by relay station 160a, and central computer 155 is just because of extremely determining further that truck 11 has arrived the appointment shovel loader.Yet, be noted that if having two ones or more shovel loader be similarly tightly near or in the radio signal transmission scope of truck, these shovel loaders just should be classified as a loading area or charging appliance to reach the purpose that data can be handled by central computer 155.

When truck 11 in the general area of specifying shovel loader 160 and truck when loading in the location (that is, move preceding, move the back etc.), the data that produced are transferred into central computer 155 by relay station 160a, and, after first bucket entered truck, the additional data that is produced was transferred to central computer 155.When first bucket entered, central computer 155 was watched in the master data archives one of them basic archives relevant for the average loading time of the specific shovel loader 160 that is used for loading this particular type truck 11 attentively.According to these basic archives, when when central computer 155 decision trucies will be needed next truck so that the loading of truck can carry out continuously by fully loaded and this specific shovel loader 160.

After last bucket enters truck 11 (through gear shift is detected to leave the loading site forward), these data are reached from the central computer 155 of another master data archives of master data file accessing; The truck that these basic archives contain this particular type dumps average walking or haulage time between the place from loading position to each difference that it can be directed.Central computer 155 goes to the record of dumping the place to analyze the estimated time of arrival (ETA) of truck according to truck Quasi simultaneously fully, and determines that to dump the area less traffic congestion will be arranged.Central computer 155 is analyzed in the way of each truck simultaneously and estimated time of arrival (ETA) just is loaded to by the specified specific truck that dumps the area of central computer to instruct, and decision plays about elapsed time from this last bucket (that is gear is shifted to preceding) when the area is dumped in truck arrival appointment.When truck 11 leaves the area of shovel loader 160 and goes to dump the area, the data of being accumulated (for example gear shift, travel distance etc.) are reached central computer 155 from the relay station 160a of trucks entering on shovel loader, and 155 of central computers estimate when this truck arrives this appointment and dump the area.

When truck arrive to be specified the scope of dumping the area, relay station 161 received any data of being accumulated by truck 11 and it is reached central computer 155.Had by the truck 11 of central computer 155 records to be walked to the travel time that dumps the area by the loading site, the suitably basic archives of master data archives just are updated with this time.(the load travel time be after loading beginning first advance shift into the time of tilt switch between starting) when truck dumped, tilt switch can be activated and represent that the data of this startup are produced by sensor processing unit 101.These data are transferred to central computer 155, and meanwhile, truck 11 can use for another load, and central computer 155 is visited and searched and determine the truck of this particular type employed is that shovel loader 160.(the truck of central computer 155 difference different loads types and different vehicle body types; For example: truck is carry coal or table soil in the operation of opening a mine).Central computer is checked the loading/travel position of every shovel loader 160, and according to:

(1) historic loading data archives,

(2) those trucies 11 have been prepared and have been sent to each load machine 160,

(3) from the historic unloaded travel time of the ad-hoc location of truck 11,

When analyze every shovel loader will need in another truck to come load.Central computer 155 is checked then from the basic travel time archives that dump area (ad-hoc location of truck) to every specific loading site.According to the travel time data, central computer 155 is checked the historic unloaded carriage return time and is determined that shovel loader will need a truck at first, and according to this decision, indicates and instruct it is sent to specific shovel loader to the truck transmission.

Meanwhile, the destination information of shovel loader is transferred to truck 11, central computer 155 is checked total time haul-cycle time of this truck from the shovel loader that is sent out away, and identifies this truck and be sent to time intermediate value haul-cycle time that all possible truck dumps the place.The fraction values of this intermediate value time is added to this intermediate value on the time, is expected to finish the haul-cycle time so that a truck to be provided (that is, dump another load) a period of time.For example, as the intermediate value haul-cycle time be 12 minutes and central computer 155 is added on 20% time so far by draft procedure, as dump data and can not in 12 minutes+20% time, conduct be deposited from this truck transmission and quilt, just central computer can be finished away to the haul-cycle time of dumping the area with the expression truck to its operator's flashing light late problem be arranged; Thus, the operator of central computer 155 can look at whether truck is cranky by traditional two-way wireless system and trucker's communication.

As the truck driver truck is parked to do a moment or of short duration rest, the driver just reminds the operator of central computer 155 to note this part thing by traditional two-way radio.According to the data of being received, the position that the operator of central computer 155 stamps the numbering of this truck and points out truck, and in a predetermined period, will not have load to betransported, and, may will there be data transmission to take place simultaneously at this.(truck can only be parked in the scope of relay station 160a or 161.In some cases, by set up the data that an interruption is transmitted by the suitable button of the selected keyboard 122 of operator, just can transmit this identical information.

When truck because fault, the operator has a rest etc. and when stopping using, central computer 155 just sends the truck that newly can supply usefulness to the loading site that former this truck of being parked (vacationette) sends to, and the loading point that will newly upgrade sends the truck that this quilt is parked to.This program can heavily be covered until the data of this truck of being parked (in vacationette break) such as expression gear shift etc. and till having represented that truck returns service.As this truck is loaded words when parking, because central computer 155 is known and this truck and must at first will be dumped before being sent out by load and this truck, therefore, not sending signal can occur.

Central computer 155 does not still receive data when finishing as the time in selected time of having a rest in a moment of truck operators or non-working time, just central computer 155 can be to glittering this truck numbering of central computer operator.The central computer operator can communicate by letter to check the state of this truck with this truck by traditional two-way radio.Find that as the central computer operator this truck is former thereby still in work, just he can stamp this truck numbering and point out that what minutes this truck will have again in work based on certain.This program continues heavily to cover until the service of dropping into again of this truck by central computer 155 or temporarily stops service.

Walk to shovel loader from dumping the area as for truck, time that central computer 155 record trucies send and expectation truck can be in the master data archives based on historic truck time of return and the schedule time in arrive and specify the loading site.If it is late that truck arrives when specifying the loading site) that is the not data transmission of indication arrival in the given time), the numbering of truck just can be glittering to the central computer operator, thus, he can communicate by letter with the trucker to check the state of this truck by traditional two-way radio set.

When central computing machine 155 detects that truck leaves the loading site and specifies when dumping the area towards one, it also follows above step.Central computer 155 is discerned a similar truck and is gone to the average transportation travel time that the area is dumped in appointment in its data archival.Do not detect further data as central computer 155 in this averaging time, just the truck numbering can be glittering to the central computer operator, thus, he can check the state of this truck.

Except receiving transmission data, supervision in the above described manner and sending the truck 11, central computer 155 more comes the various trucies 160 of monitors identified by identification with the relay station 160a that the truck data are sent to central computer.In view of the above, it analyzes specific shovel loader 160 load average data hourly and/or load tonnage hourly when data are sent to central computer 155, and what minutes analysis has between every load.When central computing machine 155 monitored each shovel loader 160 by data transmission, if it detects shortage from given trunk source load information, its can be to the numbering of glittering this trunk source of central computer operator (or shovel loader).Central computer 155 operators can communicate by letter with loader operator by traditional two-way radio, and whether discern this shovel loader cranky.As this specific shovel loader 160 is not in work, and loader operator can be reacted him to the operator of central computer 155 and how long will do not had in the time of work.Then, the operator of central computer 155 does not import central computer in the indication of working with this shovel loader in a specific period.

Central computer 155 should the specific period percent provided a buffering range period mutually with an estimation.When finished this period that has increased, central computer 155 checked that the transmission state of shovel loaders 160 also determines whether its loading data occurs.As do not have loading data to occur from this shovel loader, and the shovel loader numbering can be glittering to central computer 155 operators once more, and thus, he can look at that with operator's inspection of this shovel loader shovel loader also will be not how long in the time of work once more.This additional period is transfused to central computer 155, and each step is heavily covered.

Operator once central computer 155 imports with this specific shovel loader 160 of expression not after work when data, and central computer sends truck 11 again, to leave this shovel loader; Any tight truck adjacent to this shovel loader then sends the signal that leaves this shovel loader by the relay station 160a acquisition central computer of shovel loader with truck 11 again; And go to the way in truck may pick up this send again the numbering before must arrival this shovel loader near.For sending, central computer 155 not will consider specific travel time again; Replace, the travel time that is sent to all loading points with the method central computer setting truck of simplifying again equates.Can avoid like this sending again otherwise any data error that may cause.

When a charging appliance in work, and this charging appliance is considered to the time of back spare unit, is automatically deposited by central computer 155, and according to program, central computer can send a vehicle or two or above vehicle automatically to this charging appliance.Perhaps, as establishment is arranged on program, central computer 155 can flash the reference numeral of this part charging appliance to the central computer operator, thus, he can be by traditional two-way wireless communication, to this charging appliance of this charging appliance operator inquiry whether work again and prepare the running so that truck can be sent to this charging appliance.The operator answers "Yes" as charging appliance, just truck can be sent to this charging appliance, central computer 155 operators import this specific charging appliance task and transportation again with keyboard.Then, central computer 155 is taken over automatic transmission work at once, and sends first truck that can supply usefulness to this charging appliance.

As central computer 155 by determined to have existence by the data that transmitted, just it sends signal to the computer operator above transport capacity and struck capacity.Be instructed to out if any surpassing transport capacity, that truck 11 of 155 indications of central computer is near an essential preventive maintenance period.One similar decision also can have made the now that indicates that exceeds struck capacity at shovel loader 160.As overproof truck 11 or shovel loader 160 once being identified and during if any the maintenance personal, truck that 155 transmissions of central computer are identified or shovel loader 155 to maintenance factory doing the work of preventive maintenance, and/or notify the maintenance personal work to the shovel loader 160.

About maintenance of equipment, as wishing, does mine management, then maintenance of equipment can merge with the transmission data of sensor processing unit 101 and central computer 155, so that maintenance of equipment is when occurring, because sensor processing unit 101 and central computer 155 can come the running time of tracking equipment to reach the shut-in time amount of tracking equipment on the contrary by data transmission, the maintenance of equipment expense just can be tracked exactly.When occur shut down time, operator by sensor processing unit 101 number function suitable utilization and by the operator number function and certainly this unit reach the data of central computer 155, just can discern an equipment and why not work, and when return service by equipment of suitable use identification that the operator numbers code; And, when produce the data that are used for and number code when reaching central computer by operator at keyboard 122, all elements that are used and supply expense can directly be imported central computer 155 by the central computer operator when this truck quit work (that is this truck is not done the transmission maintenance in work).The code of transmission maintenance is imported in the sensor processing unit 101 by the operator's code on keyboard 122 and as data transmission, when truck returned service, the element of maintenance transmission and the expense of supply were imported in the central computer by the computer operator.If yet when truck returns service, can not know the actual cost that transmission is keeped in repair at once, the operator of central computer 155 still can be after knowing its expense input element and supply expense, be used for where reaching and when cause, so that, returning timely equipment what discern according to the data that transmitted by sensor processing unit 101, do not distribute and this section relevant maintenance element and expense of supply in shut down time by central computer in each time of working time.

By above as can be known, the raw data that vehicle-mounted weighing equipment provides for sensor processing unit 101 can be transferred into central computer and do storage and analysis, then, processed with indication that truck and operator's efficient are provided with by analyzing the various parameters of opening a mine based on the raw data of transmission, the truck performance just can improve, thus the basic charge of reduction operation heavy type, off highway truck.
