Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator group supervisory control, and more particularly to an elevator group supervisory control system capable of appropriately controlling the overall operation of a plurality of elevators.

[0002]

2. Description of the Related Art As shown in Japanese Patent Laid-Open No. 59-48369, an elevator group management control system includes an operation control system for assigning hall calls and an operating parameter and a program for collecting and learning operation status data. A system composed of learning and intelligence systems that generate

In the call allocation method, which is one of the group management controls in the conventional operation control system, when a hall call occurs, an allocation evaluation value is calculated for each elevator car, and the car with the best evaluation value is selected. It is common to assign a hall call. As a result, the operating efficiency is improved and the waiting time for hall calls is shortened. However, the allocation evaluation value in this method selects the optimum No. in the situation immediately before the hall call occurred, and the positional relationship of the hall calls before and after the allocation was made, the occurrence of car calls, etc. It was not taken into consideration, and it was easy to drive dumplings, and there were problems such as long waits due to changes in the situation after allocation.

Several proposals have been made to solve these problems.

In Japanese Patent Publication No. 57-52314, a planned stop floor of an elevator is detected, and an evaluation value for the planned stop floor is weighted smaller as the distance from the hall call generation floor becomes larger. A method of preventing dumpling operation by making it easier to allocate calls generated near the floor is disclosed.

Further, as a method for solving this problem by controlling the time intervals between the elevators, there is the following method. That is, in JP-A-62-121186, the generated hall call is provisionally assigned, and at the time of the provisional assignment, an index indicating a deviation between an estimated arrival time interval at a specific floor of each elevator and an average operation interval is assigned and evaluated. A method is disclosed in which, by performing comprehensive evaluation in addition to the formula, allocation is performed so that each elevator car is dispersed at the average operation interval in the current time zone, and dumpling operation is suppressed.

Japanese Patent Laid-Open No. 63-8179 discloses a method of predicting and calculating a time interval between elevators when a new hall call is generated, and calculating an evaluation function so that the time interval is within a reference range to perform weighting. Is disclosed.

JP-A-1-226676 discloses that in order to adjust the time interval between elevators, a priority allocation zone is divided by the driving direction and position of the elevators, and the reference interval, which are equally spaced in time or position. There is disclosed a method of canceling dumpling operation and improving service performance by setting and performing allocation evaluation together with estimated waiting time and the like.

Japanese Laid-Open Patent Publication No. 2-110088 discloses the time or space of each car based on the predicted car position and the predicted car direction after a predetermined time has elapsed in response to a car call and an assigned hall call in sequence from the present time. A method for predicting the interval and performing allocation, car control, and waiting by this is disclosed.

Further, in Japanese Patent Publication No. 61-15028, by adding to the evaluation formula whether or not to stop on a crowded floor,
A method for improving the problem of hall call allocation caused by the occurrence of a car call on a crowded floor is shown.

Further, Japanese Patent Application Laid-Open No. 1-231780 proposes a control method in which the load sharing of each elevator is made uniform by limiting the number of times that the elevator is stopped during one-cycle operation to a predetermined number.

[0012]

Among the above-mentioned prior arts, a method of facilitating the allocation of hall calls generated in the vicinity of a floor that stops in response to a call is to allocate hall calls to one elevator one after another, There is a possibility that other elevators that do not have a call assignment may become unbalanced, such as being stopped when the car call service is finished, and the effect becomes unstable depending on the assignment state to each elevator.

Further, in the method of setting the zones at equal intervals in time, the priority zone may be set at a position greatly separated from the car position, which may cause a call to the car or a full-occupancy on a crowded floor. In some cases, the elevator interval may not be controlled as desired.

The method of adding stop / non-stop to a congestion floor to the evaluation value is to suppress the hall call allocation of the floors that will be serviced after the elevator scheduled to stop on the congestion floor and to allocate it to other elevators. However, even for elevators that do not plan to stop at the passenger-occupied floors to which the hall call in the front is assigned, the hall call is assigned again after the preceding elevator departs from the crowded floor, and congestion is caused by the car call. In many cases, it will be stopped on the floor, and eventually there will be a problem that the hall call in the front will have to wait long.

Further, the method of limiting the number of stops per round to a predetermined number cannot equalize the load sharing when the traffic demand changes drastically. Especially, when the traffic demand suddenly increases, there is a risk that the transport capacity and the service performance are extremely deteriorated.

An object of the present invention is to allocate hall calls to each elevator so that they are evenly spaced in time. In other words, while referring to past driving history and forecasted traffic demand, the operating sequence of each elevator will be carefully considered based on the current assigned hall calls, car calls, and congestion in the car, and the time interval of each elevator in the future. In order to keep it even and to take into account car calls that are expected to occur, make an operation plan and include this as one of the evaluation factors to allocate hall calls to reduce long waits and improve service performance. It is to provide a group management system for elevators.

[0017]

SUMMARY OF THE INVENTION In the present invention, an overall operation plan is prepared based on a forecasted traffic demand, driving history, and congestion in each car based on an assigned hall call and a registered car call or a registered predicted car call.

Next, for each elevator, a batch service hall call with a car call, a specific hall call or a car call, a hall call with a reverse interruption, a hall call with a zone change, a hall call with a priority call on all floors, and a response decision Set a concrete operation plan such as taking charge of the hall in front of the call. Further, based on the set operation plan, priority is given to the allocation of hall calls for each floor or each floor for each elevator according to the direction, and each operation plan evaluation value that deserves normal, suppression, guidance hold, and selection prohibition is obtained and the operation plan evaluation value table is obtained. Set.

When a hall call occurs, a service evaluation value including at least the waiting time for the person is calculated, a composite evaluation value is calculated from this and the previous operation plan evaluation value, and the hall call allocation elevator is selected.

[0020]

According to the present invention, an operation plan can be prepared so that each elevator becomes equal in time or space, and then a specific operation plan for each elevator can be set. Based on this, the operation plan evaluation value can be set so that the hall call allocation is given priority or suppressed for each floor or each floor for each elevator. Therefore, the above objective is achieved by controlling or giving priority to the operation plan evaluation value.

For example, an operation plan is prepared so that the number of stop floors per revolution of each elevator is made uniform from the operation history and the existing calls and predicted calls, and the floors of each elevator are service-matched with car calls and car calls. , A concrete operation plan is decided in consideration of the congestion elimination floor in the car, the floor where the driving direction can be reversed, and the overlap between multiple elevators.

By setting an operation plan evaluation value based on this and performing a composite evaluation with the conventional service evaluation value, an imbalance in load between elevators and an unbalance in serviceability between floors will not occur. Allocate hall calls. These are intended to improve service performance.

[0023]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the embodiments shown in FIGS.

FIG. 1 is a flow chart of a hall call allocation process according to the present invention. A detailed example of the input information table T01 is disclosed in Japanese Unexamined Patent Publication No. 1-226678. For detecting traffic flow information transmitted from the elevator machine control device to the group management control device and traffic demand. Input information such as load (number of people) in the car, information on boarding / alighting, elevator position, registration status of car calls, and predicted arrival time based on the input information, predicted number of people in car or congestion prediction data in car, and hall call allocation And guidance hall call signals, and car call and hall call duration data.

When a new hall call is generated in the hall call registration processing P01 or an allocation request is generated due to the allocation review, the multi-target service evaluation processing P02 is started,
Based on the data in the input information table T01, a plurality of control targets that are conventionally used for call allocation, such as waiting time and congestion of passengers and others, boarding time, and reservation guidance system such as reservation change and car call first-come-first-served basis. Is calculated, and a multi-target service evaluation value is calculated by comprehensively evaluating the evaluation values according to a predetermined rule. The respective evaluation values and the total evaluation value are sequentially obtained for each elevator and temporarily stored in the multi-target service evaluation table T02.

The operation planning process P03 has a fixed cycle,
For example, it is activated every one second, an operation plan is prepared based on a predetermined rule of the elevator, and control information for each elevator regarding each plan item is set in the operation plan setting table T03.

The operation plan evaluation process P04 reads out the operation plan of each elevator from the data of the operation plan setting table T03, obtains the operation plan evaluation value for each elevator, direction, floor or floor, and enters the operation plan evaluation table T04. Store sequentially.

Similar to the multi-target service evaluation process P02, the composite evaluation process P05 is started each time an allocation request is generated, and the values of the multi-target service evaluation table T02 and the operation plan evaluation table T04 are evaluated in a composite manner, and each elevator is evaluated. Sequentially stores the composite evaluation value of No. in the allocation table T05. Then, in the assigned elevator selection process P06, the optimum elevator is selected based on this composite evaluation value to perform hall call assignment.

K is the elevator No., the multi-target service evaluation value is φ _s (k), the operation plan evaluation value is φ _p (k), and a constant for adjusting the ratio of the service evaluation value and the operation plan evaluation value to the allocation evaluation is set. K _p, when the round time to base the trip plan evaluation value and RTT, composite evaluation value [Phi (k) can be expressed by the following equation.

[0030]

[Equation 1]

[0031]

[Equation 2]

In the assigned elevator selection process P06, the elevator having the minimum composite evaluation value Φ (k) is selected as the assigned elevator. However, in the case of the formula (Equation 1), when the value of the composite evaluation value Φ (k) becomes larger than the predetermined value, the reservation guidance is reserved or the allocation is reserved.

Further, when the method of the formula (Equation 2) is adopted, when the operation plan evaluation value φ _p (k) is 8 and when it is 2 or less, it is described in Level 1 and Levels 6 to 8 described below. By executing the allocation exception processing, it becomes possible to put a stronger operation plan into execution.

Next, an example of setting the operation plan evaluation value φ _p (k) recorded in the operation plan evaluation table T04 will be shown. The operation plan assignment priority level is set according to the priority order shown in the flowchart of FIG. Each evaluation value L is set for each elevator, direction, floor or floor.

Level 1: Elevator designated allocation (also set when the allocation is changed) L = 100 Level 2: Mandatory priority allocation (may be allocated to multiple units. Also in case of re-allocation request) ...... L = 99 to 51 Level 3: Priority allocation ...... L = 50 to 26 Level 4: Normal allocation ...... L = 25 Level 5: Allocation suppression ...... L = 24 to 5 Level 6: Allocation suppression・ Information reservation ・ ・ ・ L = 2 Level 7: Allocation excluded (cannot be allocated) ・ ・ ・ L = 1 Level 8: Hall call allocation reservation on the floor ・ ・ ・ L = 0 Fig. 2 shows a specific example of operation plan planning process P03 It is a flow chart which shows an example.

First, in step 31, as preparation for operation planning, it is determined whether or not to execute the following processes, and other initial settings are made. That is, various rules can be set in the operation plan. It can be selectively used as necessary depending on the time zone, traffic demand, the number of operating vehicles, and control targets such as energy saving according to customer preference, but here, the case where all four rules are adopted will be described. In addition, the forecasted traffic demand for each floor and direction and the zones where it is easy to pass through will be extracted. Furthermore, the operation position relationship of each elevator is investigated and prepared for the following operation plans 1 to 4.

In order to allocate hall calls so that the time or positional intervals of the elevators are made equal in step 32, an operation plan for time-equalized control for setting zones for prioritizing and suppressing the allocation for each elevator Process 1 is performed.

Next, at step 33, the priority value is set in consideration of the actual car call and the assigned hall call.

When allocating hall calls, if there is a crowded floor between the elevator position and the assigned hall call, there is a high possibility that a large number of car calls will be registered by passengers boarding from that floor. Therefore, it is highly possible that the predicted arrival time of the floor ahead of the crowded floor will be significantly increased from the time when the hall call was generated and assigned. At that time, regarding an elevator that stops at a congested floor, a method of suppressing the allocation of a floor in front of the congested floor to be serviced after stopping at the congested floor and allocating to an elevator that is not scheduled to stop at a subsequent congested floor can be considered. However, after being assigned to the subsequent elevator, the preceding elevator departs from the congested floor, a new hall call is generated on the congested floor, the subsequent elevator also stops at the congested floor, and many car calls are registered. Therefore,
Assigning a hall call ahead of the crowded floor to the preceding elevator will provide faster service. Also,
If an elevator that does not have a call for allocating a hall on a congested floor arrives at the congested floor before reversing the direction on the intermediate floor, the transportation capacity for the congested floor will be reduced and the service performance will be reduced. In order to improve these problems, the number of vehicles arriving at the congested floor and the order of departure are set systematically in advance to control the operation.

Therefore, first, in step 34, the order in which each elevator departs from a specific floor such as a crowded floor is set based on the current car position and call generation status.

Next, in step 35, the elevator that is scheduled to arrive at the first crowded floor is given a value that facilitates the allocation of hall calls in the front, and the elevators that are scheduled to arrive at the second and third floors on the crowded floor are boarded. Control is performed to suppress the allocation of hall calls in the area in front of the congested floor.

Further, in order to prevent the processing of step 35 and the deterioration of the service of the floor in front of the crowded floor due to the occurrence of the crowded floor, the car position, the call situation and the arrival order to the crowded floor in step 36. For example, HCR (High Call Return) or LCR (Low Call) that reverses the direction on the way floor without servicing a specific succeeding elevator to a congested floor
Return) Plan operation. That is, in order to do this, the direction reversal elevator is selected and the direction reversal floor is planned, and it is determined whether or not a problem occurs in the overall transportation capacity, and the operation plan is set in the operation plan setting table T03, It is used to set the operation plan evaluation value in the operation plan evaluation process P04.

FIG. 3 shows an embodiment of a flow chart of the time equalized allocation zone setting process in step 32. First, in step 3201, the interval dt _ab of each elevator is calculated. The car position at that time is the floor position by direction, not limited to the floor position where the elevator is actually located, but as the floor position where the elevator can be stopped at the current speed, or the elevator floor position predicted after a certain period of time elapses. Is also good. Further, a is the elevator and b is the succeeding elevator immediately after. The interval dt _{ab of} each elevator is obtained from the estimated arrival time table which is calculated in advance by the number of floors and the number of calls.

Next, in step 3202, the reference time interval D is obtained. The round trip time RT, which is the sum of the interval dt _ab of each elevator calculated in step 3201, is obtained by the equation (3), and the value obtained by dividing it by the number of elevators N is set as the reference time interval D, and is expressed by the equation (4). To be done.

[0045]

[Equation 3]

[0046]

[Equation 4]

At step 3203, the interval dt _ab between this elevator a and the succeeding elevator b immediately after is equal to the reference time interval D.
Determine if greater than. If the elevator interval dt _ab is larger than the reference interval, the start point F _sa of the allocation zone giving priority to the hall call allocation of this elevator a is set to the current floor position F of this elevator a in step 3204.
_Let a. If the elevator interval dt _ab is smaller than the reference interval, the position F _bD obtained by adding the value f (D) obtained by converting the reference time interval D into the number of floors to the position F _b of the succeeding elevator b immediately after in step 3205. calculate.

Next, at step 3206, this elevator a is
It is determined whether or not there is a hall call or a mold call which the elevator a handles between the floor positions F _a to F _bD .

If there is no call, the start point F _{sa of the} zone giving priority to the hall call allocation of this elevator a is set to F _{bD in} step 3207. If called, step 32
At 08, the starting point F _{sa of the} zone that prioritizes the hall call allocation of the own elevator a is the floor F _ay having the call closest to F _a . After the starting point F _{sa of the} zone for prioritizing hall calls is determined in steps 3204, 3207, and 3208, a value f (D) obtained by converting the reference time interval D into the number of floors is added to the starting point F _sa in step 3209. The floor position is calculated and used as the end point _{Fea of the} priority zone.

When the start point F _sa and the end point F _{ea of the} priority zone are determined, the floor is set in the operation plan setting table T03 in step 3210. The processes of steps 3203 to 3210 are performed for each elevator, and it is determined in step 3211 whether all elevators have been completed, and the process is repeated until all elevators are completed.

Further, by making the allocation restraining zone from the current position of each elevator immediately after each elevator to the start point of the priority zone, it is possible to perform hall call allocation so as to keep the elevators at equal intervals.

Next, a concrete operation plan example of the operation plans 3 and 4 by the processing of steps 34 to 36 will be described.
An example will be described with reference to FIG. 5, in which the number of floors and the number of service floors is 12 and the congestion floor F1 is the first floor. Now, it is assumed that the elevator A E _A is traveling on the 5th floor, the elevator B E _B is on the 10th floor, the elevator C E _C is on the 4th floor, and the elevator D E _D is on the 12th floor. At this time, in step 34, the order of departure from the crowded floor F1 is set in the order of the C-unit E _C , the B-unit E _B , the A-unit E _A , and the D-unit E _D.

Of these, the unit A E _A has an assigned hall call H _{A in the} upward direction on the second floor, and therefore LC at step 36.
It is designated as Unit R, the current position 5th floor down to the crowded floor F1 is set as the allocation prohibition zone Z1 _A , and the second floor uphaul call H _{A and} thereafter are set as the priority allocation zone Z2 _A, which is excluded from the processing of step 35. .

[0054] In step 36, the elevator C Unit E _C is the first to depart then from the crowded floor F1 is crowded floor F
In order to give priority to the floors ahead of 1, down from the 4th floor of the current position to the congested floor F1 is the hall call allocation suppression zone Z1 _C, and the range from the 1st floor up to the 5th floor up of the congested floor F1 is prioritized Zone Z2 _C is set, and floors above the sixth floor are set as normal allocation zone Z3 _C. Elevator No. B E _{B, which} is scheduled to depart from congestion floor F1 to the second, has priority allocation zone Z1 _B from the sixth floor down to the first floor, which is congestion floor F1, and allocates ahead of the second floor up after congestion floor F1. Set in suppression zone Z2 _B. Elevator No. D, E, which will arrive at congestion floor F1 for the third time
_D is the priority allocation zone Z1 _D from the 11th floor down to the 7th floor, the normal allocation zone Z2 _D from the 6th floor down to the first floor which is the congestion floor F1, and the guidance reservation zone Z3 _D after the congestion floor F1. Set. By setting the allocation zone in this way, it is possible to prevent the long waiting of calls in front of the congested floor and the deterioration of the transportation capacity of the congested floor, thereby improving the service performance.

FIG. 5 shows a concrete woman who has set the operation plan in the operation plan setting table T03. Operation plan 1 is step 3
2. Record the start floor and end floor of the priority range or suppression range of each elevator by the time-equalized allocation zone setting function. In operation plan 2, the floor of the call closest to the car position is recorded in order to set the priority / restriction zone in consideration of the currently assigned real call. In operation plan 3, in step 34, the departure order from the specific floor of each elevator by the departure order of the specific floor and the assignment control of the distance farther than the specific floor of step 35, the priority by the assignment control of the far distance, the start of the control range,
Record the ending floor. In the operation plan 4, the floor for which the driving direction reversal (HCR or LCR) designated in step 36 is performed, and the priority range and the start floor and the end floor of the suppression range due to the floor are recorded.

FIG. 6 shows a concrete example of the process of setting the operation plan evaluation value in the operation evaluation process P04. In the operation plan evaluation process P04, based on the set values related to each operation plan recorded in the operation plan setting table T03, operation plan evaluation values of eight stages are provided for each elevator, direction, and floor in the operation plan evaluation table. Set to T04. First, in step 401, initial processing is performed. Step 4 below
From 02 to step 422, the floor is determined. In step 423, the direction is determined. In step 424, the loop process for each elevator is performed to obtain the respective levels.
In 1, the operation plan evaluation table T04 is set with the operation plan evaluation value according to the level.

First, in step 402, it is determined whether or not the floor to be processed is a non-stop floor, and if it is a non-stop floor, step 4
03 specifies level 7 exclusion. If it is not a non-stop floor, it is determined in step 404 whether the floor to be processed is in the priority range of the time-equalized allocation zone of plan 1,
If it is within the priority range, priority allocation of level 3 is set in step 405. If the floor to be processed is outside the priority range, it is determined in step 406 whether or not it is within the suppression range. If it is within the suppression range, the level 5 allocation suppression is set in step 407, and if outside the suppression range, the step is determined. Level 4 at 408
Set to normal allocation of. When it is determined in step 409 that the floor to be processed is within the priority range and there is a call with the current position of the elevator, in step 410, the forced priority allocation of level 2 is performed based on the actual call consideration zone setting of plan 2. Set to. Next, in step 411, it is determined whether or not the elevator to be processed is the designated elevator for the specific floor distant allocation suppression of plan 3. If it is not the designated elevator, proceed directly to the next. In case of designated elevator, step 41
If it is determined in 2 that the floor to be processed is within the priority range of plan 3, it is set to the forced priority allocation of level 2 in step 413. If it is outside the priority range, it is within the control range of plan 3 in step 414. Or not. If it is within the restraint range, level 6 assignment restraint / guidance is suspended at step 415, and if it is outside the restraint range, the process proceeds to the next step. next,
In step 416, the elevator to be processed is the HCR of plan 4.
/ LCR It is determined whether or not the designated elevator has priority. If it is not the designated elevator, the process proceeds to the next processing, and if it is the designated elevator, it is determined in step 417 whether the floor to be processed is within the priority range of plan 4.
If it is within the priority range, level 2 is set in step 418. If it is outside the priority range, it is determined in step 419 whether it is within the suppression range of plan 4. If it is within the control range, the level 8 hall call allocation is suspended, and if it is outside the control range, proceed to the next step. By performing these processes in the order of the priority of the plan, the level finally set for the plan of the high priority is achieved. From the level thus set, the evaluation value is set in the operation plan evaluation table T04 in step 421.

At steps 422, 423 and 424, it is determined whether all floors have been completed, both ascending and descending directions have been completed, and all elevators have been completed, and the above processing is performed with respect to all elevators, directions and floors.
