Description
Technical field
The present invention relates to a kind of road vehicle weighing system, the part of weighing that relates in particular in this road vehicle weighing system is settled.
Background technology
What at present, dynamic weighing system of road vehicle generally adopted is weighting platform formula and bended plate type.
Weighting platform belongs to static weighing apparatus but not dynamically weighs from structure and principle, global range (external in removing) is all only used it as the static state weighing apparatus.Say that from technical standpoint weighting platform is a kind of substitute, being used for weight metering charging is that unavoidable selection---highway division has application demand, but domestic most of producer does not grasp dynamic weighing apparatus technology, and weighting platform can only be provided.The problem that the truck scale of weighting platform formula mainly exists has excavated volume big, road structure destroyed greatly, and long construction period, dynamic measurement error is big, can not be used for high-speed weighing, and the later maintenance workload is big.
Bent plate (Bending Plate), nineteen sixty-eight comes out, it is the Automobile Dynamic weighing apparatus of first generation large-scale application, its principle is a pre-stressed steel plate that tiles on ground, obtain the weight of vehicle by the output that is attached to the strain resistor on the steel plate, infer car weight by the distortion of steel spring plate in fact exactly.The problem that bended plate type exists mainly is that bent plate is in use owing to slit between bent plate body and framework and the basis needs periodic cleaning, there are circuit and device in bent plate inside, must carry out encapsulation process, the regular repairing of bent plate waterproof sealing material, maintenance workload is big, and overall life is subjected to the restriction of steel plate number of times fatigue lifetime.
Summary of the invention
The technical issues that need to address of the present invention have provided a kind of dynamic weighing system of road vehicle, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:

Fig. 1 is a structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
As seen from Figure 1: the present invention includes: vehicle detection part, weigh part and controller part; Described vehicle detection partly comprises: first ground induction coil 1 and second ground induction coil 2; The described part of weighing comprises: first row's LOAD CELLS 3 and second row's LOAD CELLS 4; Described first row's LOAD CELLS 3 and second row's LOAD CELLS 4 respectively two rows on the vehicle forward direction, before and after dividing on the road surface, on about the road surface; Before first ground induction coil 1 is placed in first row's LOAD CELLS 3, before second ground induction coil 2 is placed in second row's LOAD CELLS 4; Described first ground induction coil 1 partly links to each other with controller with second ground induction coil 2; Described first row's LOAD CELLS 3 and second row's LOAD CELLS 4 link to each other with charge amplifier in the roadside rack 5, and charge amplifier links to each other with controller analog interface partly;
Described first row's LOAD CELLS 3 and second row's LOAD CELLS 4 are one group with two 1m feldspar English piezoelectric sensor series connection respectively.
Vehicle detection of the present invention partly adopts two ground induction coils, and (2000 * 1000mm), first ground induction coil is arranged on the preceding 300mm place of first row's LOAD CELLS, and second ground induction coil is arranged on the preceding 300mm place of second row's LOAD CELLS; Ground induction coil output signal access controller digital interface.
The part of weighing is one group with the series connection of two 1m feldspar English piezoelectric sensors, two rows before and after on the road surface, dividing, about each one group of sensor, front and rear row is 2176mm at interval.Two sensors picks out the two-way insulated cable, is linked in the charge amplifier in the rack of roadside, and the analog interface of charge amplifier and controller is communicated with.
Controller part middle controller hardware using embedded system, communication component adopts and to grind magnificent PCM3718 address card, software adopts the VC exploitation, mainly is responsible for signals collecting, data computation and transmission.Charge amplifier also is arranged in rack place, roadside together with controller.The voltage analog signal that controller software imports into by digital signal and two sensors to the ground induction coil input, carry out parking stall logic analysis, waveform intellectual analysis and calculating, accurate instantaneous velocity, wheels weight can be provided, stress, gross weight, axletree number, axletree be long, can be in conjunction with the model data storehouse, carry out vehicle and differentiate, can exceed the speed limit, a series of detections such as unbalance loading, overload.
The present invention is divided into from physics and logical organization can be divided into three parts, and first is the vehicle detection part, and major function is to be used for detecting vehicle whether to enter the weighing area, and can carry out the branch car; Second portion is the part of weighing, the main hardware unit that produces a dependent variable when tire presses parts; Third part is a controller, and the delta data that can gather second portion according to the signal prompt of first draws weight, and the row communication of going forward side by side passes to related system.
Prior art mainly is exactly that the technology defectiveness that part adopts because second portion is weighed has caused various problem.The present invention has adopted the quartzy piezoelectric sensor of line style as the second portion parts of weighing.
The present invention adopts the quartzy piezoelectric sensors of two line styles to connect, and divides left-right and front-back to lay two groups on the bicycle road, and the sensor insulated cable inserts the charge amplifier in the controller of roadside, by charge amplifier access controller analog communication interface; Adopt two groups of ground induction coils to be laid on two row's sensor front end, by data line access controller digital communication interface; When vehicle sails the weighing area into high speed, at first can produce a high level and enter controller through a ground induction coil, notification controller begins to carry out the calculating of weighing of a new car; LOAD CELLS on the pressure wheel then, faint strain electric charge enters charge amplifier and amplifies, be input to the controller analog interface, controller is preserved whole voltage data and is changed, leave the weighing area according to next ground induction coil signal determining vehicle and just begin whole waveform is calculated, draw weighing results.
