Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device for an elevator, and more particularly to a selection method and a control device for selecting an elevator serving a generated hall call.

[0002]

2. Description of the Related Art Conventionally, as a control method of this type, control has been performed for a long time in which the departure time interval of a standard floor is controlled and the time intervals between elevators are made as uniform as possible.
After that, zone control was performed so that the area of responsibility for each elevator was determined and the elevators were operated at regular intervals even after departure from the standard floor. Furthermore, with the development of microcomputers, a method has been established in which individual hall calls are managed and controlled by an evaluation formula so that the waiting time is minimized. The evaluation formula in this method is set for each time zone. In addition, JP-A-59-2236
No. 73 introduces the technology of measuring traffic flow for each building and creating an evaluation formula for each traffic flow. Further, in Japanese Patent Laid-Open Nos. 59-26873 and 59-223672, there is a method for improving the traffic demand by switching the traffic demands by switching the evaluation formulas used for the front and rear traffic flows. Stated.

Further, in Japanese Patent Laid-Open No. 1-13385, when it is necessary to change a hall call, a driving situation is displayed,
A method for registering a new evaluation calculation method from the outside is described.

[0004]

In these conventional examples, it is premised that the traffic flow for which the above-mentioned evaluation formula is valid continues for a certain time or longer, and when the traffic flow is switched or the corresponding evaluation formula is set. In the case of a traffic flow that cannot be determined as a specific traffic flow, sufficient performance cannot be exhibited. JPA
As described in JP-A-59-26873 and JP-A-59-223672, if the control methods used in the front and rear traffic flows are combined and controlled at the time of switching, the control can be switched smoothly. However, the traffic flow during the transitional period is special, and it is not possible to sufficiently provide the service during the transitional period by combining the evaluation formulas for servicing the steady traffic flow. In addition, Japanese Patent Laid-Open No. 1-13385 makes it easy to artificially switch the evaluation formula from the outside, and the evaluation formula is not automatically switched. No consideration is given to making an evaluation that suits the situation at that time.

[0005]

[Means for Solving the Problem] The hall call collecting means collects the generated hall calls and sends them to the information storing means. The car information collecting means collects car information such as car calls and the number of people in the car, and sends it to the information storage means. The evaluation formula selection means selects an evaluation formula suitable for the current situation or changes the evaluation formula based on information such as the number of unserviced hall calls in the information storage means every time a hall call is allocated. The hall call is assigned using the selected or changed evaluation formula.

The evaluation formula selecting means selects the evaluation formula to be used for the next hall call allocation when the current situation changes such as execution of hall call allocation, service termination of elevator users, generation of re-allocation request, or the like. Make a change.

Further, while having a switching means, while the current situation is suitable for a preset condition, allocation control is carried out based on an evaluation formula determined for each traffic flow and time zone under the condition, and is assumed in advance. If a situation that deviates from this condition occurs, a different assignment evaluation formula is adopted for each hall call.

[0008]

The hall call collecting means collects hall call information for each floor, and the car information collecting means collects car information such as car calls and sends it to the information storage means. The allocating means determines an elevator that serves a hall call generated by an evaluation formula predetermined by the evaluation formula selecting means. The evaluation formula selection means determines an allocation evaluation formula of a hall call to be generated next based on the allocation result and the current situation. The evaluation formula is determined not only after the evaluation of the allocation but also at any time when the situation changes such that the elevator arrives at the destination floor, a new car call is registered, or a long wait occurs. By preparing the evaluation formula to be used next after the end of allocation or when the situation changes, it is not necessary to judge the traffic flow mode, and control is performed according to the time zone and traffic flow mode at that time. A group management control that does not require a mode can be realized without changing the method.

In addition, normally, when the traffic flow or the like exceeds a preset range by the switching means by performing the control defined for each time zone and traffic flow mode, the switching means uses a certain evaluation formula. By switching from the method of performing allocation control to the method of determining the evaluation formula to be used each time hall call allocation is performed, allocation is performed according to the evaluation formula set for each traffic flow while the traffic flow does not change, When the traffic flow changes from the expected one, a method of reselecting the evaluation formula for each call assignment can be adopted. As a result, if the traffic flow does not change, it is possible to realize control that improves the efficiency of the entire time zone by the conventional method, and the traffic flow changes and the preset evaluation formula cannot achieve sufficient performance. in case of,
It becomes possible to make allocations corresponding to changes.

[0010]

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is an overall configuration diagram of the present invention.

Information of the hall call buttons 101 to 10n is sent to the hall call collecting section 31 of the group management control device 3 through the transmission line 2. The hall call collection unit 31 collects hall call information of each floor, and the car information collection unit 32 collects car information such as car calls and stores it in the traffic information storage unit 33.
Send to The allocation control unit 34 determines an elevator that serves the hall call generated by the evaluation formula determined by the evaluation formula determination unit 35 in advance. The evaluation formula determination unit 35 refers to the evaluation formula table 36 based on the traffic information collection unit allocation result and the current situation, and determines the allocation evaluation formula for the next hall call. The evaluation formula is determined not only after the evaluation of the allocation but also at any time when the situation changes such that the elevator arrives at the destination floor, a new car call is registered, or a long wait occurs. Thus, by preparing an evaluation formula to be used next after the end of allocation or when the situation changes, it is not necessary to determine the traffic flow mode. For this reason, it is not necessary to change the control method depending on the time of day, the traffic flow mode, etc., and the group management control without the mode can be realized.
41 to 44 are car call buttons, 51 to 54 are car information transmission lines, 61 to 64 are machine control devices, 7 is a group management signal transmission line, 81 to 84 are motors, 91 to 94 are hoisting machines,
111 to 114 are cages, 121 to 124 are counterweights, and 131 to 13n are hall display devices.

FIG. 2 is a flowchart showing the outline of the present invention. (A) shows the flow of operation of the present invention. First of all, when receiving the occurrence of a hall call (201),
The traffic information collecting unit 33 collects and grasps the current elevator position, hall call assignment status, car call occurrence status, number of passengers, elevator stoppage, operation, door opening / closing, etc. (202), and then The evaluation formula determination unit 35 selects and modifies the evaluation formula for evaluating each elevator based on the present situation (203). further,
The allocation control unit 34 determines an elevator to be serviced by the hall call generated based on this evaluation formula (20
4).

In the actual program, the detection of the hall call occurrence (201) as in (b) is performed by the main program, and when it is detected, the steps (202) to (204) are executed and not detected. Then, the subsequent processing of the main program is executed. In the main program, collect the car information (2
05), collection of hall call information (206), calculation of arrival time of each car (207), prediction of full capacity (20)
8), calculation of hall call duration (209), calculation of car call duration (210), and other processing such as reservation change (211).

A conventional elevator operation system is shown in FIG.
The daily traffic flow as shown in Fig. 3 (a) is divided into several time zones as shown in Fig. 3 (b), and the control method is determined so that appropriate control is performed for each time zone. are doing. This does not change regardless of the allocation method or zone method, and the same control method is used during that time, assuming that the assumed traffic flow continues for a certain time. this is,
For example, the traffic flow is modeled as a stepwise change like the rectangle shown by the arrow in FIG. Therefore, no method has been considered for smoothly shifting to the traffic flow transition time zone. For this reason,
The transition time was far from the expected control method, and it was used even though the control method was not appropriate, and the connection before and after was not considered.
Also, no matter what the actual traffic flow is, it was classified as one of the predetermined traffic flows and the evaluation formula for that traffic flow was used. there were.

Therefore, in the present invention, for example, FIG.
As in (c), the current situation is judged for each hall call from the number of passengers getting on and off within a certain period, the number of current hall calls, and the number of car calls, and the allocation evaluation formula to be used is determined. I chose Based on this, the assigned elevator is selected, so that the evaluation criteria are suitable for the situation at that time. As a result, it becomes possible to perform assignment control according to the situation of the place regardless of the traffic flow mode.

Here, the case where the evaluation formula is used has been described, but the control method selected in each state is not limited to the allocation control, and may be a start / stop condition of each elevator.

Next, an operation example of the present invention will be described.
In the following, we will describe the case where the average waiting time is shortened in the situation where the traffic volume gradually increases and the traffic flow shifts from quiet to normal congestion. In the case of a quiet time when the number of hall calls and car calls is small as shown in FIG. 4 (a), the average waiting time is selected by selecting the elevator that takes the shortest time to reach the generated hall call. Can be shortened. Therefore, in a situation where both hall calls and car calls are small as shown in FIG. 4A, the selection time is the minimum arrival time to the hall call. Next, when congestion starts and the number of hall calls increases as shown in Fig. 4 (b),
Most elevators already have an assigned hall call. In such a situation, when the elevator to be assigned to the generated hall call is determined, the waiting time of the already assigned hall call is often affected. In order to reduce the average waiting time in such a situation, it is better to select the service elevator by the "maximum waiting time minimum method" that also considers the effect on the already assigned hall calls.
Therefore, the evaluation criterion here is that the maximum waiting time of the hall call of each elevator is the minimum.
If the congestion gets worse and the hall calls are generated on many floors as shown in Fig. 4 (c), the load each elevator takes up in order to shorten the time it takes for the elevator to go up and down this time. By securing the transportation capacity per hour by averaging the number of stops during that period, the waiting time will be shortened as a result. Therefore, in this case, the evaluation criterion is that the one-round time or the average value of its predicted values is the minimum. However, since it is difficult to predict the one-round time in real time and use it for allocation control, it is an evaluation criterion to average the number of times the load is taken up by each elevator, specifically, the number of stops while going up and down as described above. Become. Separately, in the case of so-called dumpling operation in which the elevators move close to each other as shown in FIG. 4D, the elevators are evenly spaced in order to shorten the average waiting time. To be Therefore, the evaluation criterion in this state is the interval between the elevators.

4 (a), (b), (c), and (d), if the situation such as the number of hall calls generated and the elevator interval changes, the minimum waiting time, the maximum waiting time minimum, the load averaging, the elevator interval. By changing the evaluation standard such as equalization, it becomes possible to realize control for shortening the average waiting time.

Next, the case of shortening the boarding time will be described. Each elevator can be evaluated based on the car call duration and the number of people in the car that can be measured with a normal elevator. Figure 5 shows few hall calls
In the situation of (a), the number of people in the car rarely exceeds a certain value, so the car call duration is used as the selection criterion.
As shown in Fig. 5 (b), even if there are many hall calls, the normal traffic flow, where there is a lot of inter-floor traffic, allows the passengers to get on and off evenly. Is the selection criterion.

When the number of hall calls is increased and the number of car calls is reduced as shown in FIG. 5C, the boarding time can be shortened by using the number of people in the car as an evaluation criterion. Therefore, when shortening the boarding time, the evaluation criterion is the number of hall calls when the number of hall calls is small, or the number of car calls when the number of car calls is large. The number of people is used as the evaluation standard. Although the number of people in the car is used here, the output of a load meter installed in the car may be used.

As described above, by changing and selecting the evaluation reference for determining the service elevator according to each situation every time the hall call occurs, it becomes possible to realize the allocation control adapted to the situation change. .

As a result, it becomes possible to realize the allocation control adapted to the situation at the moment of allocation. However, depending on the situation, the control method used for allocation may change significantly and frequently, and the control may become unstable.
In such a case, the history of the allocation evaluation up to that time is stored, and the evaluation formula used for the allocation is determined so as not to disturb the previous allocation determination, and such a case is also dealt with. can do.

FIG. 6 is a flow chart when the evaluation formula is determined after the allocation is completed. Main program is Figure 2
Is the same as. (A) shows the flow of the operation. After detecting (201) the occurrence of a hall call, the evaluation formula determined as the one to be used when the next hall call occurs is used in advance. Assign (204),
Next, grasp the situation such as the number of unserviced hall calls (2
02), selecting and changing the evaluation formula based on this situation (203), and further detecting whether the situation has changed due to completion of hall call service (401), and if it has changed (202) ), Select an evaluation formula and change it again.

As described above, if the evaluation formula is selected beforehand according to the situation after the previous allocation, the time from the occurrence of the hall call to the determination of the service elevator can be shortened. The response time from the occurrence to the guidance of the service elevator can be suppressed within a predetermined range, and the immediate reservation system becomes possible.

FIG. 6 (b) shows an example of an actual program implementation method. When the main program detects the occurrence of a hall call, the steps (204) to (202) and (203) are executed to change the situation. When is detected, the process is executed from (202) and returns to the main program.

FIG. 7 shows an embodiment in the case of switching to the traffic flow mode system. The group management control device 3 has a traffic flow mode determination unit 37 and a traffic flow mode-based evaluation formula table 38. The traffic flow mode determination unit 37 determines which of the preset traffic flows the current traffic flow is suitable for, and if there is a traffic flow that matches the current traffic flow, the traffic flow name is assigned and controlled. Send to section 33. The allocation control unit 33
An evaluation formula for servicing the sent traffic flow is selected from the traffic flow mode-based evaluation formula table 38 to determine the elevator to service the hall call. Traffic flow mode determination unit 3
If the one applicable to the current traffic flow in 7 is not in the preset traffic flow, it is assigned to the allocation control unit 33.
Tell. After receiving this information, the allocation control unit 33 determines the service elevator based on the evaluation formula determined by the evaluation formula determination unit 35 for each hall call.

FIG. 8 is a flowchart showing the flow when switching to the traffic flow mode system. First, when the occurrence of a hall call is detected (201), the traffic flow mode determination unit 37 determines whether it is a preset traffic flow (601). If the traffic flow has been set in advance, the allocation control unit 33 causes the traffic flow mode-based evaluation formula table 3
The service elevator is determined using the evaluation formula of No. 8 (602). If it is not the set traffic flow, the steps (202) to (204) are executed in the same manner as in FIG. 2, and the service elevator is determined by a different evaluation formula for each hall call. In this part, the evaluation formula is decided before the hall call is generated as shown in FIG. 4, so that the response time from when the hall call button is pressed until the service elevator is guided is kept within a predetermined range and the immediate reservation system is adopted. it can. In this case as well, the main program is the same as in FIG.

FIG. 9 is an explanatory diagram when switching to the traffic flow mode system. If the same traffic flow continues for a certain period of time like a, c, e, g in Fig. 9, allocation control should be performed using an evaluation formula whose compatibility has been confirmed in advance by simulation or the like. Is often efficient, and the connections between the front and back are often good.

However, the timing of switching the traffic flow hatched as shown by b, d, and f in FIG. 9 is not suitable regardless of which evaluation formula is used. Therefore, when such a transition time or other traffic flow that is assumed in advance is different, the control method of the present invention is applied to reselect the evaluation formula for each hall call and use a more suitable evaluation formula. It is preferable that the allocation is performed by

According to the present embodiment, when the traffic flow assumed in advance depending on the time zone continues for a certain period, that is, the time zones a, c, e, and g in FIG. By continuing to use the evaluation formula, it is possible to maintain the same efficiency as before and the consistency with the front and rear hall calls, and when the traffic flow deviates from the assumed traffic flow,
At the time of transition, that is, in the time zones of b, d, and f in FIG. 7, improvement can be made by using an evaluation formula suitable for each situation for each hall call, so that the performance of the entire day traffic flow is improved. Can be guaranteed.

FIG. 10 shows an embodiment in which a neural network is used for the evaluation formula decision unit. The information sent from the traffic information collection unit 33 is stored in the situation memory 351 as current information. This information is sent to neural network 352. Neural network 3
In the input layer 52, the current number of hall calls, the number of passengers getting on and off within a certain period of time, the number of car calls generated, etc. are input, and the number of the evaluation formula to be used as a result is output. According to the present embodiment, since the selection of the evaluation formula can be obtained by learning by the neural network, the present invention can be executed even when the relationship between the situation and the evaluation formula is not obtained numerically.

FIG. 11 shows an embodiment in which it is determined by a neural network that the traffic flow is unknown. This is a traffic flow determination unit used as a part of the traffic flow mode determination unit 37, except that it is determined whether or not the one determined by the neural network 353 is a previously assumed known traffic flow. Is the same as. In this case, a means for selecting a traffic flow according to the current situation is prepared separately. According to the present embodiment, it is determined by the neural network whether or not the evaluation formula is a known traffic flow prepared, and if it is an unknown traffic flow, the modeless allocation method is executed. You do n’t have to
In addition, it becomes possible to make a determination quickly.

FIG. 12 is a flow chart when the evaluation formula is selected and changed based on the number of unserviced hall calls. The situation is the same as that of FIG. 2 except that the number of unserviced hall calls is used as the above situation (202-1).

The number of unserviced hall calls is one of the indexes that accurately represent the relationship between the number of installed elevators and traffic flow and the capacity of the currently available elevator group. The number can be used to identify the evaluation formula to be used. FIG. 13 is an explanatory diagram in the case of being based on the number of unserviced hall calls. The number of unserviced hall calls in a given situation has the following properties. One of the evaluation indexes showing the capability of the elevator is one lap time, which is the time until the elevator makes one round trip up and down and returns, and the number of people the elevator can transport is determined depending on this time. This cannot be determined until the elevator makes one round trip. It is not directly related to the response time of individual hall calls. The number of hall calls that have not been serviced is the number of hall calls that must be serviced from now on, and if it is considered as the time required to make one round from now on, it can be regarded as one round time in the future. Therefore, it is possible to estimate the transport amount and load that each elevator will be responsible for from this number.

Therefore, for example, when the number of hall calls is smaller than the number of elevators that can be used, the waiting time can be shortened by selecting the elevator that minimizes the waiting time before answering the generated hall call. However, if the hall call exceeds a certain value, the assignment evaluation considering the congestion in the car will be performed so that the load of each elevator will be equalized. Also, if the maximum number of hall calls handled by one elevator exceeds a prescribed value, or if there is a difference in the number of hall calls handled by each elevator, the evaluation formula should be calculated from the waiting time center of each floor. By changing the load center of each elevator, allocation control suitable for the situation can be performed.

Further, as shown in FIG. 13 (b), an unserviced hall call shows a cross section of the current traffic condition, and may be considered to correspond to the current traffic flow. Because it is possible, it is possible to accurately reflect the current load situation and quickly respond to changes in the situation such as traffic flow.

FIG. 14 is an explanatory diagram in the case of being based on the number of hall calls or a predicted value thereof within a certain period. Using the number of hall calls within a certain period has the same effect as taking the moving average of traffic flow changes, as shown in the figure. Instead of determining the evaluation formula with the unserviced hall calls in FIG. 12, the program may determine with the number of hall calls within a certain period. As compared with the number of unserviced hall calls in FIG. 12, the response to changes in traffic flow is slower, but stable control with good connection to the past can be realized.

FIG. 15 is an explanatory view when the number of car calls is taken into consideration. By adding the number of car calls, it becomes possible to understand the traffic flow including the destination, and it becomes possible to allocate more appropriately to the situation. For example, if a hall call is represented by a triangle and a car call is represented by a circle, the number of hall calls is concentrated in the upper and lower parts as shown in FIG. 15 (a) and the floor spaces as shown in FIG. 15 (b). Any of the moving shapes is as shown in FIG. 15C, and these cannot be distinguished. Then, when the car call is included in the evaluation, Fig. 15 (a)
As in (d), FIG. 15 (b) becomes as in FIG. 15 (e), and these can be distinguished. As a result, more detailed control suitable for the situation can be realized corresponding to each car call.

FIG. 16 shows an embodiment in which the evaluation formula is described as a functional. In a building where characteristic traffic flows such as concentration, divergence, and floors are main, it is sometimes possible to describe the evaluation formulas suitable for each situation and the relationship between the situations as a functional. In such a case, the evaluation formula is described as a functional 354, and the situation memory 351 is written every time the situation changes.
By assigning the value of each situation in a variable to a variable, an evaluation formula is determined, and the hall call is assigned by this evaluation formula. In this embodiment, since the building and the traffic flow for which the functional can be obtained are few, the applicable range is limited, but since only one formula needs to be prepared to obtain the evaluation formula, the configuration of the device can be simplified. .

FIG. 17 shows an example of the evaluation formula table. Prepare a combination table for each situation, predetermine the evaluation formula for each combination, and describe it in the table. According to this method, although limited to the range described in the table, it is possible to quickly perform the processing from the situation determination to the determination of the allocation evaluation formula.

FIG. 18 shows an embodiment in which the evaluation formula is described by a membership function. Describe the evaluation formula for each judgment item in the form of fuzzy rule 355,
The evaluation formula 356 is represented by the logical sum of the conclusions of the rules and is output as a function. This function is an evaluation formula, and the allocation control unit 34 determines an evaluation value based on this function and determines the service elevator. According to this embodiment, since the evaluation formula is created in the form of fuzzy rules, it is easy to add rules later.

In FIG. 19, the evaluation formula is determined for each time,
It is an embodiment in the case of making a decision by referring to a table for each time.
FIG. 19A is a block diagram of the group management control device, which is the same as FIG. 5 except that there is a clock 39 for knowing the time. The evaluation formula table 36 is determined for each time and the number of hall calls at that time, as shown in FIG.
And the evaluation formula for selecting the service elevator for the hall call generated according to the evaluation formula table 36. This evaluation formula should be set according to the individual situation, and at the same time, the evaluation formula for each time should be set so that the evaluation formula used for the next traffic flow can be smoothly transitioned, and the control before and after the connection should be performed well. Therefore, it is possible to prevent a long wait and the like caused by the switching of control.

[0043]

According to the present invention, it is possible to perform accurate control suitable for the situation at that time for each hall call, and shorten the waiting time, the long waiting rate, the congestion degree in the car, the boarding time, etc. Can be improved. In particular, at times when traffic flow changes, which is difficult to deal with with conventional evaluation formulas that are fixed for each time zone and traffic flow, it is possible to prevent unexpected passage of people, etc.
The operation performance of the elevator can be greatly improved.
