Embodiment 1
First, referring to figs. 1 through Fig. 9, the cluster management system involved by embodiment 1 is described.The feature of the cluster management system involved by embodiment 1 is, using any one car in the car that connects up and down as benchmark car, and only this benchmark car is carried out to the computing of path evaluation value, for other cars, its path evaluation value is set as identical with the path evaluation value of benchmark car, and selects the car distributing to hall call on the basis of this.
As shown in Figure 1, the elevator cluster management system involved by embodiment 1 manages control part 1 primarily of group, multiple stage (N platform) double-deck elevator (60,61,62), the upper car control setup (50,51,52) controlling the upper car (70,71,72) of double-deck elevator, the hall call register device 90 of lower car control setup (40,41,42) and the elevator lobby that is arranged on each floor that controls the lower car (80,81,82) of double-deck elevator are formed.
Group's management control part 1 is such as made up of computing machines such as microprocessor, DSP (Digital Signal Processor, digital signal processor), system LSI and Personal Computers.Group's management control part 1 possesses operation management control system 10, learning system 20 and intelligent system 30, and operation management control system 10 possesses input control part 11, destination path specification setting section 12, destination path generating portion 13, predicted path generating portion 14, path evaluation functional operation part 15, comprehensive evaluation value arithmetic section 16 and elevator and selects part 17.
In each double-deck elevator 60,61,62, two cars connect up and down, and are arranged in a hoist trunk.In two cars connected up and down, car (lower car 80,81,82) is on the lower assigned to the car control setup 40,41,42 of lower car, the car (upper car 70,71,72) of top side is assigned to the car control setup 50,51,52 of upper car, and group manages control part 1 and the upper car 70,71,72 in double-deck elevator and lower car 80,81,82 controlled as independent car.It is the same that each car control setup and group manage control part 1, such as, be made up of the computing machine comprising microprocessor etc.In addition, in the present embodiment, have employed the structure with the car control setup 40,41,42 of lower car and the car control setup 50,51,52 of upper car, but also can carry out the upper car of each double-deck elevator and the control of lower car by a car control setup, and employing manages group the mode identifying upper car and lower car in control part 1 independently.In addition, in the present embodiment, be described for the control of double-deck elevator, but the control of other elevators that the car that the present embodiment also can be applied to more than three connects up and down.In addition, in the present embodiment, it is all double-deck elevator that group manages the multiple elevator that control part 1 controls, but the present embodiment also goes for the occasion that simultaneously there is double-deck elevator and single-deck elevator.
There is respectively operation board 100 in car in each car, in this car, possess destination floor registration button 101 in operation board 100.
The information relevant with the operation of each elevator is stored into group from the car control setup 40,41,42 of lower car and the car control setup 50,51,52 of upper car and manages the input control part 11 of control part 1.
In addition, carry out registration call by the hall call register device 90 being arranged on the elevator lobby of each floor, after each registration hall call, all store in input control part 11 floor information registered and with rising or the relevant solicited message that declines.
In addition, if generate car call by the destination floor registration button 101 of operation setting in car on operation board 100, then for each car, and exchange between input control part 11 and actually provide the information of the destination floor needed for service.
Except above-mentioned various information, in input control part 11, also store patronage in car and car location information, call number, effectively number of elevator that each car has has accepted, service floor information, elevator information and the specification information etc. such as the specification information relevant to each car that pre-enter.These information are examples for the information be stored in input control part 11, can also store other information as required in input control part 11.In the present embodiment, the distribution control of elevator is carried out according to above-mentioned input information.
The object of the present embodiment is, comprise the occasion that the multiple stage cars such as double-deck elevator are arranged on the elevator in a hoist trunk with connecting up and down being managed the multiple elevator that control part 1 carries out operation management by group, also by predicting operating path in the future, such as elevator controlling is become to be in state at equal intervals in time, suppress thus so-called " beading operation ", to improve operating efficiency.
In destination path specification setting section 12, identify current traffic according to the running state of the every day be accumulated in learning system 20, and decide the specification of destination path according to this information.That is, manage in the learning system 20 in control part 1 group, traffic is learnt according to the elevator informations such as car position and upper and lower elevator number and destination floor information, and judge that what operation procedure is more applicable at this time point, therefore, according to online input information, identify the number of elevator up and down of each floor representing flow of the people in building belongs to which feature mode in the feature mode representing representational traffic in building.According to the building telecommunication flow information (using the statistical information of the flow of the people of elevator) of time dependent or corresponding time point, judge the traffic recognized.The specification of destination path is decided according to above-mentioned traffic.The specification of destination path is set as " keeping at equal intervals in time " in principle.
Destination path generating portion 13 generates destination path according to the specification determined by destination path specification setting section 12.Referring to Fig. 3 and Fig. 4, the generation method of the destination path in this destination path generating portion 13 is described.The figure of the running orbit of Fig. 3 destination path that to be the figure of running orbit of the destination path before representing temporal adjustment at equal intervals, Fig. 4 be after representing temporal adjustment at equal intervals.The information needed for destination path of generation is the prediction service direction of elevator, and the running orbit in path changes according to being ascent direction or descent direction.In addition, current elevator location information, the service available the superiors and the information such as orlop and command speed is also needed.These information generate the MIN information needed for destination path, by making consideration to the operation information of elevator, can generate more accurate destination path.
In figure 3, regulation time is set as during current point in time is to the interval supposition time 303 of setting arbitrarily, when the specification of destination path is set to keep at equal intervals in time, interval infers that the objective 304 of upper car at time 303 place and the objective 305 of lower car are set to the objective meeting destination path specification.Under the state of Fig. 3, keep at equal intervals in time owing to not being adjusted to, so the running orbit 302 of the running orbit 301 of the destination path of upper car and the destination path of lower car is not by being set as that the objective 304 of upper car and the objective 305 of lower car of time 303 are inferred in interval.
Destination path generating portion 13 is according to " time keeps at equal intervals " this condition determined by destination path specification setting section 12, the respective destination path of the upper car in regulation time and lower car is adjusted, makes upper car and lower car respectively towards the objective 304 of upper car and the objective 305 of lower car.When adjustment aim path, according to the position of each car of current point in time, adjust in the position of time-axis direction to the direction rollback point in the destination path before adjustment, carry out the adjustment of destination path thus.As shown in Figure 4, be adjusted to temporal at equal intervals after, the destination path 401 of upper car and the destination path 402 of lower car infer the objective 404 of time 403 respectively by upper car and the objective 405 of lower car at arbitrary interval.By said method, can generate during making the running orbit of each car after regulation time and become equally spaced destination path.
In predicted path generating portion 14, for the hall call information obtained by hall call register device 90, effective car in generation forecast path is wanted in interim distribution, with generation forecast path.Now, when generating the predicted path of each car, as shown in Fig. 5 to Fig. 8, generate two predicted paths, one is the predicted path being assigned with hall call and having needed to consider the impact of stopping hall call generation floor, and another is predicted path when not being assigned with hall call and not stopping hall call generation floor.
Fig. 5 is the predicted path of lower car when not stopping hall call generation floor, and Fig. 6 is lower car is needed lower car when making lower car stop hall call generation floor predicted path by distributing hall call temporarily.Known by comparing Fig. 5 and Fig. 6, not stopping the predicted path 506 of hall call and stopping in the predicted path 606 of hall call, stop the predicted path 606 of hall call closer to destination path 602.Equally, Fig. 7 is the predicted path of upper car when not stopping hall call generation floor, and Fig. 8 is upper car is needed upper car when making upper car stop hall call generation floor predicted path by being assigned with hall call temporarily.Known by comparing Fig. 7 and Fig. 8, not stopping the predicted path 706 of hall call and stopping in the predicted path 806 of hall call, do not stop the predicted path 706 of hall call closer to destination path 701.
In addition, when generating destination path and predicted path, the stop that the calling for having accepted is carried out to also be considered.Now, in double-deck elevator, also to consider to be the impact that calling that a car has has accepted is carried out stopping.
In path evaluation functional operation part 15, carry out computing according to the path evaluation function of path distance index to the part as distributive judgement.Path evaluation function is the index representing the degree that predicted path and destination path are close, and as shown in the dash area of Fig. 5 to Fig. 8, represents with the area of the figure formed by predicted path and destination path.
The car that selecting paths evaluation function is little, namely selects the car of track closer to destination path of predicted path, can be kept equally spaced elevator in time.In common elevator, by adopting this function, the what is called " beading operation " (with reference to patent documentation 1) that can prevent multiple stage car from running as the pearl be worn together, and in double-deck elevator, when a certain car in the car connected up and down is assigned with hall call and starts to travel to provide service, another car also starts to travel in linkage.That is, two cars connected up and down can not become at equal intervals in time, so in the destination path of operation of looking ahead is evaluated, needing unites with the car of a side considers.
To achieve these goals, in the present embodiment, the operation result of the path evaluation of upper car is set as identical with the operation result of the path evaluation of lower car, and selects the lift car distributing to hall call on the basis of this.As mentioned above, by only when path evaluation computing by path evaluation operation result and the opposing party unified, and other adopt the control identical with common elevator, thus, for double-deck elevator, the computing machine identical with usual elevator also can be used carry out best distribution.
In the present embodiment, using lower car as benchmark car, and by upper car as will be unified car object, its reason is only because when two cars of independent control double-deck elevator, the numbering of lower car is less than the numbering of upper car, but do not represent must using lower car as benchmark car.Such as, in order to make the nearer car of distance provide service for hall call, also can be arranged to for the calling towards ascent direction, using upper car as benchmark car, for the calling towards descent direction, using lower car as benchmark car.In addition, in the double-deck elevator with floor height adjustment function, when carrying out floor height adjustment, certain car existed as benchmark, so also can be arranged to this car as benchmark car.
In addition, when generation forecast path and destination path, be necessary to make consideration to the service floor of each car.That is, double-deck elevator is because of the reason of the configuration aspects in its building, place, and sometimes there is the floor that cannot provide service, so when generation forecast path and destination path, need making consideration by service floor, this point is very important.Such as, in the building of common 10 layers, do not arrange the occasion in the space that can enter for a car being called as false floor in the superiors and orlop, effective service floor of lower car is 1 layer to 9 layers, and effective service floor of upper car is 2 layers to 10 layers.On the other hand, in the building of 10 layers being provided with false floor, effective service floor of upper car and lower car is 1 layer to 10 layers.For the double-deck elevator be arranged in usual building, in the occasion that effective service floor of each car is different, change the method for benchmark car according to the difference of the floor that there occurs hall call or utilize when generation forecast path and destination path the Measures compare of the Composite service floor synthesized by the service floor of upper and lower Ge Tai car effective.
When utilizing Composite service floor, owing to also needing to make consideration to the stop of the hall call accepted, so preferably make consideration to the stop of the hall call that upper and lower Ge Tai car has has accepted further.That is, in order to carry out best distribution according to specification, select the benchmark car of current point in time the best, the calculating of path evaluation value is carried out to path metric, and is the path evaluation value of a car by this path evaluation primary system one.
The predicted path 906 of lower car that Fig. 9 represents path evaluation primary system one when being the path evaluation value of a car and the example of destination path 901.
In comprehensive evaluation value arithmetic section 16, according to the path evaluation value calculated in path evaluation functional operation part 15, comprise other evaluation number, the comprehensive evaluation value of computing each car.Except path evaluation value, also there is the evaluation number of actual wait time evaluation number etc., the elevator information of this moment, hall call information and car call information etc. are taken in.
Select the operation result selected in part 17 according to obtaining from above-mentioned comprehensive evaluation value arithmetic section 16 at elevator, and be predicted to be on the basis considering various information and carry out the elevator of optimum operation instantaneously at this.
As mentioned above, the cluster management system involved by embodiment 1 also can carry out the operation management roughly the same with common elevator to double-deck elevator, so double-deck elevator can be managed together with common elevator.
Below, be described with reference to the motion flow of Fig. 2 to the cluster management system involved by embodiment 1.

In step ST102, decided the specification of destination path by destination path specification setting section 12.Be set as in principle keeping in time at equal intervals.In step ST103, according to the specification of the destination path determined by destination path specification setting section 12, generate destination path by destination path generating portion 13.In step ST104, be confirmed whether to have carried out the allocation process of car to hall call.When having carried out the allocation process of car to hall call, entering step ST105, when also not carrying out the allocation process of car, having returned step ST101, carrying out the renewal of input information.In step ST105, by comprehensive evaluation value arithmetic section 16, comprehensive evaluation value calculation process is carried out to each the object car that group manages control part 1 unified management.In step ST106, by predicted path generating portion 14 generation forecast path.When generation forecast path, according to the hall call information obtained in step ST104, for the hall call as object, generate two predicted paths, one is predicted path when stopping, and one is predicted path when not stopping.The process carried out in each step of above-mentioned steps ST101 to step ST106 is identical with the cluster management system of single-deck elevator described in patent documentation 1 with computing.
The feature of the cluster management system involved by embodiment 1 is, adds the step of step ST107 to step ST110.That is, in step ST107, double-deck elevator is determined whether.When being judged as YES double-deck elevator, entering step ST108, when being judged as not being double-deck elevator, entering step ST109.In addition, in the cluster management system involved by embodiment 1, double-deck elevator is identified as the elevator linked together by two cars, and determines whether double-deck elevator according to the data preset.In step ST108, determine whether the computing of lower car.When the computing being judged as YES lower car, enter step ST110, when the computing being judged as YES upper car, enter step ST109.In step ST110, carried out the computing of distributive judgement according to path distance index by path evaluation functional operation part 15.As shown in Fig. 5 to Fig. 8, the area of the figure formed by predicted path and destination path is to represent path evaluation function.In step ST109, carry out the process path evaluation value of upper car being set as the path evaluation value identical with the path evaluation value of the lower car obtained in step ST110.
In step ST111, carry out the computing of wait time evaluation number.Wait time evaluation number can adopt and be set to the methods such as prediction latency time when temporarily distributing each car for de novo hall call and decide.In step ST112, carry out computing by comprehensive evaluation value arithmetic section 16 and distribute final the comprehensive evaluation value used in control.Additive operation is weighted to described path evaluation value and wait time evaluation number.In the evaluation number of the present embodiment, also consideration is made to the evaluation number etc. gone out according to the state evaluation of elevator, be not limited in and use wait time evaluation and path evaluation to distribute.In step ST113, carry out ending process of comprehensive evaluation value calculation process.Ending process of comprehensive evaluation value calculation process is after the corresponding comprehensive evaluation value calculation process of a kind of number of elevator to carrying out unified management terminates, the process of end loop process.In the cluster management system of Fig. 1, after the computing of 1 ~ 2N platform car terminates, carry out ending process of comprehensive evaluation value calculation process.In step ST114, according to the comprehensive evaluation value obtained in step ST113, part 17 is selected to select can carry out the car of optimum operation in this moment by allocated elevators.The process carried out in each step of above-mentioned steps ST111 to step ST114 is identical with the cluster management system of single-deck elevator described in patent documentation 1 with computing.
As mentioned above, in the cluster management system involved by embodiment 1, only a car in two cars connected up and down is carried out to the computing of path evaluation value, the path evaluation value of the opposing party's car is set as identical with this car, and select the car distributing to hall call accordingly, thus, for double-deck elevator, also can control to keep equally spaced mode in time to carry out best distribution.

Embodiment 3
Below, with reference to Figure 11 to Figure 18, the cluster management system involved by embodiment 3 is described.The feature of the cluster management system involved by embodiment 3 is, when carrying out path evaluation functional operation to the car of either party in the car connected up and down, the stop of the opposing party's car is also taken in.
Also can infer from the explanation of embodiment 1, when carrying out distribution control according to destination path evaluation to single-deck elevator, predicted path processing section 14 in operation management control system 10 shown in Fig. 1, for new hall call, generates a predicted path to a car., in double-deck elevator, two cars work in a hoist trunk with the state connected.So, when side's car has accepted calling (hall call and car call) wherein, the car (self car) being assigned with registered calling not only corresponds to registered calling and stops, and also stops linkedly with the stop of another car be connected on self car (the other side's car).
Therefore, when generation forecast path, if what generate is the operating path of single-deck elevator, need to make consideration to entrance hall call information and car call information, if what generate is the operating path of double-deck elevator, then also need to make consideration to the stop of self car of the stop interlock with the other side's car further, so be necessary to make consideration to the call information and elevator information etc. of the other side's car.
In addition, when generating the operating path of single-deck elevator, in the occasion of adjacent floor bid, re-starting path evaluation, being created on the operating path that two floors are stopped continuously.; if up and down car separates the interval of a floor and the double-deck elevator that links together, then, when there occurs identical situation, also consider the stop of the other side's car; generate and only need to stop operating path once, operating efficiency can be improved further under these conditions thus.So, in embodiment 3, when carrying out path evaluation functional operation to the car of in the car connected up and down, by the stop of the opposing party's car is also taken into account, the distinctive operating efficiency of double-deck elevator can be improved, can be controlled by the distribution realizing eliminating " beading operation " to the prediction run in the future.
Illustrated in Figure 11 to Figure 16 have with white triangles shape represent accept calling time predicted path.In the following description, suppose that distributing hall call is assigned to lower car.When distributing hall call and being assigned to lower car, the new hall call represented with black triangle if occur, then the predicted path generating portion 14 in the operation management control system 10 shown in Fig. 1 generates operating path when stopping new hall call A07 and operating path when not stopping new hall call A07.Wherein, Figure 11 is the predicted path of lower car when not stopping new hall call A08, and Figure 12 is predicted path when lower car being allocated to temporarily new hall call A08.As can be seen from Figure 12, when distributing hall call and being assigned to lower car, if generate predicted path when new hall call A08 being allocated to lower car temporarily, then this predicted path becomes the operating path that lower car is stopped continuously at floor one by one.
Figure 13 is the predicted path of upper car when not stopping new hall call A08, and Figure 14 is predicted path when upper car being allocated to temporarily new hall call A08.In figs. 13 and 14, due to registered calling C07, D07 are allocated to lower car, so made consideration to the stop of lower car.In addition, in Figure 11 to Figure 14, the predicted path of Figure 12 is closest to destination path, and the destination path evaluation number of its path metric is the highest.
Here it should be noted that the elevator of the present embodiment is double-deck elevator.The predicted path generated in fig. 12 is the operating path of floor stop one by one, and the original object of double-deck elevator is as described in the beginning part, is to improve transporting power and operating efficiency by reducing dock floor.Therefore, as the due control of original double-deck elevator, when there occurs the calling of continuous floor, should not carry out the operation that above-mentioned floor is one by one stopped, but calling should be distributed to upper car and lower car respectively, make by once stop just can respond Figure 14 distribute hall call D07 and new hall call D08.
The operating path of the upper car of double-deck elevator and the desirable of lower car has been shown in Figure 15 and Figure 16.The car distributing to registered calling E07 is changed to the operating path after upper car from lower car by Figure 15, and Figure 16 is operating path when new hall call F08 being allocated to lower car.
In order to realize the operating path of the upper car of the double-deck elevator shown in Figure 15 and Figure 16 and the desirable of lower car, when continuous floor there occurs hall call, generation forecast path again.Now, iff the destination path evaluation seen in the future, then the evaluation of property can decline at equal intervals, but manages control as the group of double-deck elevator, can realize temporal equally spaced while, improve overall operating efficiency.
Below, be described with reference to the action of Figure 17 and Figure 18 to the cluster management system involved by embodiment 3.
Step ST101 in the motion flow of the cluster management system involved by embodiment 1 shown in each step with Fig. 2 of step ST301 to step ST305 is identical to step ST105.In addition, the step ST113 in the motion flow of the cluster management system involved by embodiment 1 shown in step ST313 with step ST314 and Fig. 2 is identical with step ST114.Therefore, in order to avoid repeat specification, omit the explanation of each step above-mentioned.
The feature of the cluster management system involved by embodiment 3 is, adds the step of step ST306 to step ST312.That is, in step ST306, determine whether double-deck elevator.When being judged as YES double-deck elevator, entering step ST307, when being judged as not being double-deck elevator, entering step ST308.In addition, in the cluster management system involved by embodiment 3, the same with the cluster management system involved by embodiment 1 and embodiment 2, double-deck elevator is identified as the elevator that two cars connect up and down, and determines whether double-deck elevator according to set data.
In step ST307, judge whether according to once service available number of floor levels the hall call (calling of continuous floor) that there occurs equidirectional.Once service available number of floor levels is such as two floors that 2 layers and 3 layers etc. are adjacent in the double-deck elevator not having floor height adjustment function.In the double-deck elevator of floor height adjustment function with an adjustable story height, such as, be 2 layers and 4 layers of such three floor.When there occurs the hall call meeting this condition, entering step ST312, when there is no the hall call meeting this condition, entering step ST310.
In step ST308, only use the car information of self car (being assigned with the car of registered calling), by predicted path generating portion 14 generation forecast path.Now, according to the hall call information obtained in step ST304, for object hall call, generate two predicted paths, one is the predicted path stopped, and another is the predicted path (with reference to Figure 11 to Figure 14) do not stopped.
In step ST309, according to the predicted path obtained in step ST308, in the path evaluation functional operation part 15 of Fig. 1, carry out common destination path control.Path evaluation functional operation part 15 carries out path evaluation according to path distance index, carrys out computing allocation evaluation value thus.Path evaluation function is described above, represents with the area of the figure formed by predicted path and destination path.In addition, wait time evaluation number is calculated, finally by comprehensive evaluation value arithmetic section 16 computing of Fig. 1 for distributing the comprehensive evaluation value of control.Additive operation is weighted to path evaluation number and wait time evaluation number.In the evaluation number of the present embodiment, also consideration is made to the evaluation number etc. gone out according to the state evaluation of elevator, be therefore not limited in and only use wait time evaluation and path evaluation to distribute.
In step ST310, use the information of self car and the car information of the other side's car (another car be connected with self car), generate predicted path by the predicted path generating portion 14 of Fig. 1.Now, too according to the hall call information obtained in step ST304, for object hall call, generate two predicted paths, one is the predicted path stopped, and another is the predicted path do not stopped.
In step ST311, carry out the distinctive destination path of double-deck elevator and control.The distinctive destination path of double-deck elevator controls the control etc. referring to the control of the step ST107 of Fig. 2 to step ST110 and the step ST207 of Figure 10 to step ST213.
In step ST312, for the hall call from object floor, again generate destination path.The details of the regeneration of destination path is described with reference to Figure 18 in aftermentioned part.After this, in step ST315, carry out ending process of comprehensive evaluation value calculation process, then, enter step ST316, select part 17 by the allocated elevators of Fig. 1, select this moment can carry out the elevator of optimum operation according to above-mentioned comprehensive evaluation value.
Below, be described with reference to the process that resets of Figure 18 to the destination path of step ST312.
In double-deck elevator, when detecting according to once service available number of floor levels the hall call going to equidirectional, start this flow process.Specifically, what simply connect at two cars does not have in the double-deck elevator of floor height adjustment function, at 3 layers of hall call that there occurs ascent direction and after having carried out allocation process, there occurs the occasion of the hall call of ascent direction at 2 layers or there occurs the occasion of the hall call of ascent direction at 4 layers, starting this flow process.Now, assuming that the hall call of the ascent direction of 3 layers is registered calling, the hall call of the hall call of the ascent direction of 2 layers or 4 layers is new calling.In addition, by double-deck elevator once service available number of floor levels be called can dock floor number.
Below, to can the calling of dock floor be 3 layers and 2 layers, registered calling is that the occasion of 3 layers is described.When each calling above-mentioned is the calling of ascent direction, carry out, from can path evaluation computing the below floor (being 2 layers in the present embodiment) in dock floor, not carrying out path evaluation computing to upper car for lower car.The path evaluation computing of 3 layers is replicated in the path computing of the lower car calculated before this.Using these path operation results as an index, carry out comprehensive evaluation.In addition, relative to registered 3 layers, allocation evaluation value time registered and this evaluation number newly calculated are compared, in the good occasion of this evaluation number newly calculated, carry out distributing altering, carrying out can by once stopping as the calling of dock floor providing the distribution of service.
Specifically, what in step ST401, start destination path resets process.Destination path reset process to all can dock floor and all car carry out circular treatment.In step ST402, judge that the hall call generated by the hall call register device 90 of Fig. 1 is the calling of ascent direction or the calling of descent direction.When the calling being judged as YES ascent direction, enter step ST404, when the calling being judged as YES descent direction, enter step ST403.In step ST403, determine whether the calling from the below floor in continuous floor.When being judged as YES the calling from below floor, entering step ST406, when being judged as YES the calling from top floor, entering step ST405.In step ST404, determine whether the calling from the top floor in continuous floor.When being judged as YES the calling from top floor, entering step ST408, when being judged as YES the calling from below floor, entering step ST407.
In step ST405, for the calling from the top floor in continuous floor, carry out the computing of the path evaluation value of upper car.Now, only upper car is carried out to the evaluation of car, carry out the process identical with ST311 with the step ST310 of Figure 17.Considering the other side's car and generation forecast path in the hall call information of self car and the basis of car call information, the computing of walking along the street footpath evaluation number of going forward side by side.In step ST406, carry out the setting of the path evaluation value of lower car for the calling from the below floor in continuous floor.Now, be replicated in the path evaluation value of the upper car calculated in step ST405, and it can be used as the path evaluation value of lower car.In step ST407, for the calling from the below floor in continuous floor, carry out the setting of the path evaluation value of lower car.Now, only lower car is carried out to the evaluation of car, carry out the process identical with ST311 with the step ST310 of Figure 17.That is, the other side's car and generation forecast path in the hall call information of self car and the basis of car call information is being considered, the computing of walking along the street footpath evaluation number of going forward side by side.In step ST408, for the calling from the top floor in continuous floor, carry out the setting of the path evaluation value of upper car.Now, be replicated in the path evaluation value of the lower car calculated in step ST407, and it can be used as the path evaluation value of upper car.
The computing of wait time evaluation number is carried out in step ST409.As the operational method of wait time evaluation number, there is the method etc. of the prediction latency time be set to when each car being distributed to temporarily de novo hall call.In step ST410, the comprehensive evaluation value used in final distribution controls by comprehensive evaluation value arithmetic section 16 computing of Fig. 1.Additive operation is weighted to described path evaluation value and wait time evaluation number.In the evaluation number of the present embodiment, also consideration is made to the evaluation number etc. gone out according to the state evaluation of elevator, be not limited in and use wait time evaluation and path evaluation to distribute.
In step ST411, determine whether the floor that there occurs the hall call distributed.When being judged as YES the floor that there occurs the hall call distributed, entering step ST412, when being judged as YES the floor of de novo hall call, controlling, so directly enter step ST414 owing to carrying out common distribution.In step ST412, evaluation number when registering in the past and this evaluation number operation result are compared, if this evaluation number operation result is better than former evaluation number, then enters step ST413, in the other cases, directly enter step ST414.In step ST413, this evaluation result is used to select best car.
Now, preferably use double-deck elevator, by once stopping as two floors provide service.For this reason, in step ST414, carry out the confirmation of circular treatment.At object car with after the process of dock floor terminates, can end process.At object car and can the occasion that also do not terminate of the process of dock floor, upgating object car or can dock floor, and return step ST401.
At this, importantly considering on the basis run in the future, by dock floor numerical control in Min., carry out path evaluation computing to keep at equal intervals in time.That is, in the present embodiment, have employed this simple method of reproduction path evaluation number, but also can reduce dock floor by Calculation Estimation value.Such as, in the calculation, when stop number of times being tailed off path evaluation number be calculated as better than common evaluation number.
According to embodiment 3, the basis considering the other side's car information is carried out the control of destination path, so the destination path that can carry out reducing dock floor controls as far as possible, the operating efficiency of double-deck elevator can be improved.But, even if when having carried out the path evaluation making dock floor tail off, because the distribution of reality also will with reference to comprehensive evaluation value, so according to the information etc. in actual wait time evaluation number, lift car, even from can the calling of dock floor, also not necessarily make upper and lower car provide service.Preferably carry out best car according to the traffic demand of current point in time to distribute.
As mentioned above, in elevator cluster management system involved in the present invention, owing to also carrying out destination path control for double-deck elevator, so equally spaced double-deck elevator can be distributed in time, the operating efficiency of this moment can be improved.
