Description

The elevator local train scheduling that disperses

The present invention relates in super high rise building, use the method for dispersing mode elevator dispatching local train, thereby make elevator by the low layer and the high-rise entrance hall that keep apart between rule by the local train service.

In habitual elevator hoist system, the wirerope of vertical counterweight has limited the real-world operation distance of elevator.In order to arrive high-rise position above this limit, normally the passenger is delivered to the top layer entrance hall, allow the passenger go to another and can deliver to elevator place more high-rise in the building to them.Yet, allow the passenger stroll about and always can cause confusion, and the stable passenger flow volume of uplink and downlink in the meeting interference building.All will go the passenger of building high level upwards to move by the building low layer.Therefore, along with the building is built higher and higher, more passenger must move by low layer, requires the building that increasing lift well (hereinafter referred to as " core body (core) ") is provided specially.If wanting to reduce keeps supplying capable passenger and arrives high-rise required core body quantity, just need to improve each elevator perpendicular and effective rate of utilization.For example, known two-seat cabin elevator can deliver the passenger of double amount during the commuter rush hour, thereby can reduce required vertical shaft only about half of.Have the scheme of a plurality of mobile cars to comprise two suspension in vertical shaft, because the ratio of wirerope, wherein the range ability of high car is two times of low car, and with line inductance electromotor (LIM) the driving elevator that is contained on the vertical shaft sidewall, thereby can cancel wirerope.Yet two suspension are not suitable for the through top layer of delivery passenger in very high building, and owing to there is not counterweight, the parts of motor and consumption of power all can be too high, and therefore, LIM is not widely used as yet.

In order to reach larger distance, lift car can move in first car frame in first vertical shaft, upwards arrive the transhipment layer from bottom, on even keel moves in second elevator car frame of second vertical shaft again, in the building, continue up then, and the like, the unsettled U.S. Patent application that this scheme can be submitted to simultaneously referring to the applicant and the application, sequence number is (Attorney Docket No.0T-2230).Because the passenger need take many times up and down, will shuttle back and forth to move with the high speed of elevator like this and conflict, also has the another kind of vertical shaft degree of utilization that improves, thereby reduce the scheme of core body demand, when it is included in passenger up and down lift car is shifted out the mode of vertical shaft, the unsettled U.S. Patent application that this scheme can be submitted to simultaneously referring to the applicant and the application, sequence number is (Attorney DocketNo.0T-2296 and 0T-2297).

In the super high rise building that has the hundreds of layer, the elevator local train of any the above-mentioned type all needs once to come and go operation with just finishing for a long time, and the time that for example returns this inlet entrance hall from an inlet entrance hall may be very long.In habitual elevator, normally determine to begin to close the time of elevator cab door with timer, thus the starting procedure that beginning once moves.Yet the passenger can be by pressing " opening the door " switch on the car operating panel or interrupting this program by the enabling gate safety switch.In the big row's elevator with very long roundtrips time of run, if control by closing the door, the time that brings into operation between each car often is fitfull very.

Purpose of the present invention is included in the dispatching method of control elevator local train in for example very high building, according to the rule and the average dispersion time of departure, thereby makes local train leave an entrance hall according to the cycle mode of rule.

According to the present invention, each lift car in one row's local train elevator only can arrive and the Shi Caineng that awaits orders brings into operation (just operation controller being responded) at this car, and by the scheduling controller (scheduler) that disperses according to the scheme forecast time of departure of disperseing to dispatch a car.According to the present invention, it has entered armed state before bringing into operation if car is in the scheduler indication, and car will wait until that the operation of scheduler notice could move in the time of can beginning.If car enter await orders before scheduler just the forecast operation can begin, car just brings into operation after awaiting orders immediately entering.

According to another aspect of the present invention, implement the dispersion of a plurality of local train elevators according to elapsed time at interval and dispatch, when bringing into operation, a car just starts the clock at interval; The delay of arbitrary lift car when bringing into operation all can make the operation of all cars correspondingly postpone, but do not influence the frequency of scheduling.

The present invention has become with a delay and has sent a car sending all cars with in short-term delay in order, rather than branch gives out all cars confusedly.Utilize the present invention, can prevent because concentrated dispatching a car caused the excessive departure interval.

The present invention has improved the efficient of handling passenger flow volume with row's local train elevator greatly, is specially adapted to high-rise building.

By can further being familiar with other purposes of the present invention, feature and advantage to the detailed description of explanatory embodiment below in conjunction with accompanying drawing.

Fig. 2 is a part of logical flow chart that is fit to the car control program that is used in combination with the present invention in the habitual elevator device of prior art.

Fig. 3 is a part of logical flow chart that is fit to the elevator local train car control program be used in combination with the present invention, and this car is the disengaging vertical shaft when passenger up and down.

The logical flow chart of Fig. 4 low layer of the present invention entrance hall height program.

Fig. 5 is used to represent a timing diagram of the present invention.

Referring to Fig. 1, row's elevator local train can comprise the 1-10 elevators that are arranged to two rows face-to-face, if transfer an elevator of given number at every turn, the next elevator of getting redy to start off is exactly the adjacent elevator of (being among the same row or the opposite, entrance hall).The elevator of representing in Fig. 1 can be an elevator commonly known in the art; Two-seat cabin elevator commonly known in the art; It as above-mentioned sequence number the elevator described in the application of (AttorneyDocket No.0T-2230 and 0T-2296), car wherein is transferred to adjacent high-rise vertical shaft from a low layer vertical shaft, just can run to and surpasses the distance that above-mentioned wirerope limited thereby make the passenger needn't leave lift car; Or as above-mentioned sequence number be the elevator described in the application of (Attorney Docket No.0T-2296 and 0T-2297), car disengaging vertical shaft wherein is moved on the platform so that passenger up and down.At one shown in Fig. 1 row elevator also can be the elevator of other types, the elevator that has nothing to do such as those and the present invention.Therefore, term used herein " lift car " can be represented has the fixedly habitual lift car of car, but also can represent to deliver the elevator car frame of the car of a parallel motion.Comprise operation control in the connotation of this term, promoted motor, wirerope, drg or the like.

In order to utilize advantage of the present invention, the running state that is produced for habitual car and revise with the method for operation controller control car.Various functions such as response car call or hall call scheduler or the like can normally be carried out.Yet, in the local train elevator, expect in advance that in the present embodiment all passengers only move between low layer entrance hall and middle entrance hall or high-rise entrance hall, and in the middle of not wanting to be parked in, in this case, the representative type program only is to need to detect the suitable closing time of going up elevator, closes the door, the identification elevator will arrive the upstream or downstream direction of another entrance hall floor, and direction initialization.Each local train has one or more elevator car shown in Fig. 2 and 3; With local train S is example.21 enter car control program fragment shown in Figure 2 from the entrance, determine with test 23 whether the direction of car is set.If no, the negative decision of test 23 just makes calling program enter other programs by return point 24.When the program by Fig. 2 in order, the final direction of the car of local train S should be to determine, therefore tests 23 positive result and can enter the step 25, sends the door that the instruction of closing the door removes to close car.Determine in test 26 whether door closes fully then.At first, door is not closed fully, and therefore, the negative decision of test 26 makes program enter other programs by return point 24.When the program by Fig. 2 in order, test 23 is sure, and car door finally can close fully, and it also can be sure therefore testing 26.From entering the step 27 here, to set one " local train S operation await orders " and indicate, it indicates the local train S operation of having awaited orders to scheduler.Determine in test 32 whether scheduler has beamed back " allowing a local train S operation " sign then.At first, unless local train has postponed for a certain reason, for example have the passenger to stop in certain time expand and close the door, test 32 should be the result who negates.If local train S is not allowed to as yet, the negative decision of test 32 just makes program enter other programs by return point 24.Finally, test 32 can obtain positive result and enter the step 33 of setting this car (being the car of local train S) operation, the step 34 that " local train S operation is awaited orders " sign is resetted, and the step 35 that " allowing local train S operation " sign is resetted.

According to the present invention, the scheme of scheduling depends on that local train finishes the needed time span of roundtrips one time, and the local train quantity in can disperseing one group of elevator of passenger flow volume.In order to determine the average operating time of local train, each local train starts a run timing device when setting operating instruction in the step 33, writes down elapsed time when next time setting operating instruction then, thereby determines the time of run of self.Yet, operating instruction leaves at car and sets when low layer entrance hall and car leave high-rise entrance hall, therefore, determine when it is up direction with going on foot 33, so that the setting of record run timing device in the step 34, and in the step 35, to be ready leaving and to reinitialize the run timing device when local train operation is carried out by the up direction of appointment in the entrance hall at car.Then, get back to other programs by return point 24.

Breaking away from vertical shaft up and down among passenger's the embodiment, if adopt the present invention, the starting point that brings into operation is that car awaits orders to set off on car frame, rather than closing the door constantly before this taken place.When car of scheduler indication of the present invention brought into operation, the operation of selecting in this example was to begin under such state, and promptly the car of parallel motion has been moved into the car frame of car, and locked in the cycle at certain hour.

In Fig. 3, the program that is used for single elevator local train can comprise the door control program 38,39 of each car that is used for local train.For example, in above-mentioned (Attorney DocketNo.0T-2296) number application, two cars are arranged, a car frame is respectively arranged in adjacent overlapping vertical shaft, and five parallel motion passenger cabins, two platforms separately on three different phases served; Ten passenger cabins are arranged in two-seat cabin embodiment.Carrying out branching program 40 can be with replacing the passenger cabin that has just arrived on the car frame at cargo-carring passenger cabin on the platform.In above-mentioned application, branching program 40 can be finished the transfer of three or four passenger cabins simultaneously.In sequence number is in the application of (Attorney DocketNo.0T-2297), branching program 40 is controlled the parallel motion of two passenger cabins between a car frame and platform simultaneously in single-seat cabin embodiment, control the parallel motion of four passenger cabins in two-seat cabin embodiment simultaneously.

Then, enter the car control program of local train S42 by entrance 43.Before the car that allows local train brought into operation, the final step of this program only comprises in test 44 had determined to have passenger cabin just can allow the program part that enters after locked in the car of local train S.Before all passenger cabins all were locked in separately the car securely, during by Fig. 3 program, the negative decision of test 44 can enter other programs by return point 45 in order.But, when all passenger cabins all are locked in the car of local train, in program part 46, will set the direction of car, away from a floor and towards another floor operation, then, step 47 is set " operation await orders a local train S " mark, and this mark is transmitted to scheduler, so that this local train of notice scheduler awaits orders to set off.Determine in test 50 whether scheduler has sent back the mark of " allowing traffic coverage car S " then.Under the representative type situation, scheduler can not return this mark, therefore will enter other programs by returning 45.Finally, test 50 positive result can arrive the step 51, sets the operating instruction of local train S, and the step 52 makes " operation await orders local train S " mark reset, and " allowing traffic coverage car S " mark is resetted.The car of local train S is under the control of their operation controllers separately at this moment.Test 54 will determine whether up the direction initialization of low layer car is.If, therefore just with its starting point, at steps 55 record time of ruies, this time is set in the run timing device, and new initialization is thought highly of in run timing in step 56 as operation, make it become the time that operation will begin.If car is moved on the platform so that in passenger's the local train car is only arranged up and down under the state that breaks away from vertical shaft, will carry out test 54 at this car.When dispatching a high rise elevator and a low layer elevator synchronously with one another, test 54 only needs to detect the direction of a car.Get back to other programs by return point 45 then.

In Fig. 4, how many cars are the first half of low layer entrance hall height program only need determine to have in eleva-tor bank, and with the quantity of recent average roundtrips time of local train, so that determine that how the scheduling interval car could be according to the mode scheduling interval car of rule divided by local train.The first of Fig. 4 program only need determine that how many local train T are arranged at present in dispatch group, and determines a new scheduling interval.Then, scheduler just waits for, up to the operation of awaiting orders of (a) local train, and (b) scheduling interval then reinitializes scheduling interval after this, is used for next local train subsequently.

In Fig. 4, enter program by entrance 80, and the car sum T reset-to-zero in 81 groups of the first step, and at steps 82 setting local train pointer n, first local train in pointing out to organize.In Fig. 1, the local train sum N that can operate in a group equals 10.Going on foot 83 total run time accumulator/accum TOTL reset-to-zero then.Determine whether be in the dispatch group in test 85 by the local train of the current indication of n pointer.If just in the step 86, make the increment of T counting machine, and the time of run (obtaining from going on foot 34 and 35) with local train n makes the total run time increment in the step 87.If local train n is not in dispatch group, portion 86 and 87 is just by bypass.In the step 87, increase the n pointer then, and with test 88 determine the n pointers whether refer to one greater than group on the numerical value of the total N of car, thereby representing that all cars have been tested finishes.If not, test 88 negative decision just makes program get back to test 85, checks that next car then is whether in dispatch group, if just increase T and total run time.After having tested all possible car, the positive result of test 88 makes program enter the step 91, utilizes the total count value in step 87 and divided by the local train quantity T that participates in scheduling, produces an average operating time.Use the mean motion time divided by T then, obtain a scheduling interval of uniform distribution average operating time.Enter test 92 then, check whether local train by the current indication of S pointer refers on the local train in dispatch group, as mentioned above, the S pointer is represented the local train dispatched in order, below also will illustrate in greater detail this point.If not in dispatch group, the negative decision of test 93 just enters the step 93, and the S pointer is pointed to next local train successively by the local train of S pointer indication.In other words, if a local train among Fig. 1 for example local train 8 after scheduling interval car 7, the S pointer will point to local train 8 not in dispatch group this moment.But, if to dispatching successively time of next local train, can be in car sum T to local train 8 countings, its roundtrips time of run can not be added in the scheduling interval, and can scheduling interval car 8 yet.If a local train in the S pointed group, test 92 positive result just enters a pair of test 96 and 97, be used for determining the local train S operation of whether having awaited orders, and whether then definite interval that begins when a last local train is scheduled.If the two one of do not satisfy, the result who negates just makes program get back to other programs by return point 98.But, entering at local train S and to await orders running state and scheduling interval under then the situation, the positive result of test 96 and 97 just enters the step 101, sets " allowing operation S " sign, and this sign is used in Fig. 2 or 3.Step 102 adopts the interval of determining in the step 91 to reinitialize intervalometer, and increases the S pointer in the step 103, gets back to other programs by return point 98 then.

Constituting with single elevator among the embodiment of local train, for example be described in the application of (Attorney Docket No.0T-2297) in above-mentioned sequence number, or constituting local train with a plurality of elevators, and among the embodiment of independent scheduling entrance hall elevator, for example be described in the pending application of (Attorney Docket No.0T-2230) in above-mentioned sequence number, test among Fig. 4 and step 96-103 suitably can use with institute shown in Figure 2 low layer entrance hall scheduler program under the situation together, so as with conspicuous mode from high-rise entrance hall scheduling interval car.If be used in two elevator devices of isochronous schedules elevator, for example be described in the application of (Attorney Docket No.0T-2296) in above-mentioned sequence number, only need to use the low layer entrance hall program of Fig. 5, because the high rise elevator in the local train is always with low layer elevator isochronous schedules.

In the expression embodiments of the invention, can in dispatch group, increase and cut down local train, and can not upset scheduler program.The local train that adds dispatch group can be with its time of run initialization, make it to become the time of run of the non-zero of arbitrary other local trains in the system, or can keep its last time of run of determining in the step 34 and 35, this time of run keeps when it is operated in dispatch group for the last time.

The present invention is based on automatic guidance: if the permission of distributing to car up and down time of opening the door of passenger too short, just can be increased to reasonable time to time of run.Although not explanation is in this article distributed to the time of opening the door to be easy to regulate, this adjusting belongs to prior art.

Fig. 5 is the timing diagram that is used to illustrate the simplification of dispersion scheduling mode of the present invention.A plurality of time cycle 1-31 among the figure just represent the time greater than a complete cycle stroke of arbitrary local train.For instance, from high-rise dispatching platforms local train 1, the starting point in the tenth one-period arrives the low layer platform in the starting point in the cycle very first time, and it returns high-rise platform in the tenth dicyclic starting point scheduling.Local train 2 only postpones two time cycles than local train 1.Time cycle 12 and 13 is represented a scheduling interval, represents with arrow 110.In the embodiment of Fig. 5, local train 3 is being met difficulty at closing time, and the starting point of preparing in the 16 cycle brings into operation.Like this, although arrow 111 expression scheduling intervals do not change, local train 3 in fact not operation the time near half of the 16 cycle.This is because during the initialization scheduling interval, be identical by the scheduling interval shown in the arrow 112 with arrow 110 and 111 scheduling intervals of indicating in the step 102 of Fig. 4.Local train 4 is not met difficulty, and therefore just obeys scheduling when scheduling interval expires immediately.The car of noticing local train 4 will stop the long period on the low layer platform, because just it had been transferred to the low layer platform when the time cycles 7 begin before postponing appears in system.Be noted that on the other hand, in the time cycle 27, car 3 was awaited orders on high-rise platform in the time of arrow 113 indication, though its arrival evening half period nearly, still be in after the scheduling interval that up to the present also not have adjusting by arrow 114 indications.Therefore, arrow 113 a bit on during scheduling car 3, just produce scheduling interval by arrow 115 indications.

The fixed time interval through overregulate that car 4 is indicated by arrow 112 in about centre of time cycle 18 responds when finishing, and brings into operation.Yet on high-rise platform, it has time enough to prepare within the sub-fraction of time cycle 28 and time cycle 29, so that leave when the scheduling interval expiration of arrow 115 indications.In other words, from this moment, car 4 has recovered regular circulation fully, just looks like the delay that does not have generation to be caused by car 3 in the time cycle 16 fully.In Fig. 5, the response of other local train 5-10 is identical with local train 4 basically, shown in arrow 116 and 117, and returns to normal operation very soon.

The explanation of Fig. 5 is at having the independently system of low layer entrance hall scheduler and high-rise entrance hall scheduler, and for example sequence number is the above-mentioned application of (Attorney Docket No.0T-2230 and 0T-2297).If high-rise and low layer entrance hall is an isochronous schedules, and only use an entrance hall scheduler program for example shown in Figure 4, will have influence on car 10 in the 16 cycle immediately by the delay that car 3 causes, because these two local train cars are scheduled together in this case.In for example sequence number is in the described this system of above-mentioned application of (Attorney Docket No.0T-2296), and the high-rise entrance hall time of departure and the low layer entrance hall that can not occur certainly as shown in Figure 5 are staggered the time of departure.

All above-mentioned patent applications all are used as the application's bibliography.

Although abovely represent and the present invention be described that with reference to illustrative examples those skilled in the art obviously can realize various changes and additions and deletions under the condition that does not break away from the spirit and scope of the present invention.
