Description

  The present invention relates to an elevator group management system.

  The elevator group management system provides a more efficient operation service to the user by treating a plurality of elevator cars (hereinafter referred to as "cars") as one group. In a general elevator group management system, up or down destination direction calls are registered at a landing, and a destination floor is registered after getting on a car that has arrived. On the other hand, a group of elevator group management system of destination floor reservation system (hereinafter referred to as destination floor reservation type group management) registers a destination floor at a landing, and designates a board for a registered destination floor. Since it is management and the destination floor of the user can be known at the time of call registration, it becomes possible to assign a suitable car to each destination floor. In the following, calls by destination floor registration at the landing will be called destination floor calls. By enabling destination floor registration only at the landing, each user must register the destination floor, and the number of people waiting can be detected from the number of registrations.

  In such destination floor reservation type group management, in order to designate a boarding car for each user, when crowded with many users, waiting customers are accumulated in front of each elevator in the elevator hall, and passengers are designated. In some cases, the flow line to the boarding vehicle may be blocked. As a technique related to such destination floor reservation type group management, techniques described in Patent Document 1 and Patent Document 2 are known. According to Patent Document 1, based on the arrangement of each car in the landing, a waiting people allowance is provided for each elevator to secure a passenger flow line, and when a new destination floor is registered, the waiting people allowance It is disclosed that the elevator to be assigned is selected in connection with. Patent Document 2 discloses a method of learning the occurrence frequency of a destination floor call for each destination floor, and assigning the destination floor call to an elevator on the far side of the elevator hall when a destination floor call having a high occurrence frequency is registered.

  However, in the technique described in Patent Document 1, in order to secure the flow line of the passengers, the waiting people tolerance value of the elevator disposed near the landing entrance is set small. For this reason, the elevator located near the landing entrance will depart with a smaller number of passengers as compared to other elevators, resulting in reduced operating efficiency. Further, in the technology described in Patent Document 2, the user of the destination floor call having a high frequency of occurrence is likely to be assigned to the elevator at the back of the elevator hall far from the landing entrance, and the user of another destination floor call Unfairness with that will arise.

In order to solve the above problems, a group management control apparatus that assigns a plurality of elevators, a destination floor registration device in which a user registers a destination floor, and an elevator responsive to a registered destination floor among the plurality of elevators. And in the group management system, the group management control device calculates waiting people evaluation value calculating means for calculating a waiting people evaluation value for each of the plurality of elevators, and a passenger from the destination floor registration device to each elevator Selecting an elevator to be assigned according to the flow line influence evaluation value calculated by the flow line influence evaluation value calculating means for calculating the flow line influence evaluation value for evaluating the ease of movement of the vehicle; and allocation control means, Bei example, said destination floor registration device provided plurality, the flow line assessment value, the combination of the plurality of destination floor registration device of the plurality of elevators it It is set to the user from the plurality of destination floor registration device when moving in the elevator is calculated as a linear sum of the wait number evaluation value of the elevator to pass through the front, an elevator group control, wherein the this Provide a system.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows an elevator group management system, which is a destination floor reservation type group management in which a destination floor is registered at the entrance of the elevator hall or its vicinity, or at the entrance of a building, and a car is allocated according to the destination floor. . In the example of the figure, an example of group management for eight elevators is shown, and eight elevator cars 3A (A) to 3H (H) and control devices 2A (A for A) to 2H for each elevator. (Group H control unit), is composed of a group management control unit 1 that centrally manages eight cars. In FIG. 1, the situation of the elevator hall on the first floor (the lobby floor) is shown (the other floors are omitted). At the entrance of the elevator hall, destination floor registration devices 4A, 4B, 4C are provided for the user to register the destination floor with a ten key or the like to create a call of the elevator. How to use the elevator with the destination floor registration device is as follows.
(1) The user on the first floor registers the destination floor with one of the destination floor registration devices 4A to 4C.
(2) The group management control device 1 allocates a car serving the destination floor to the registered destination floor.
(3) The assigned car name is displayed on the destination floor registration device.
(4) The user sees it, goes to the location of the displayed car, and waits for the arrival of the car in front of it.
(5) When a car arrives, a destination floor is already assigned to the car, and the user can reach the target floor without registering the destination floor in the car.

  Hereinafter, the details of the group management control device 1 will be described. While data input / output / storage means 101 receives information on control devices of each car, information on car landings of each floor and information on each car, control commands and output information from the group management control device are control devices for each car, It is output to each device at the landing. Among the input information and the output information, necessary information is stored by the storage device. The hall / car information management means 102 stores the position and direction of each car, the number of passengers in the car, the assigned destination floor, and the number of calls for each destination floor. The waiting number counting means 103 according to the number of machines counts the number of waiting people for the destination floor call registered at the landing of each floor. Here, the waiting number of people may count the number of destination floor calls assigned to each unit as the waiting number, or a camera or an infrared sensor is installed at the landing to count the number of users before each number, It may be corrected with respect to the number of destination floor calls assigned above.

  The facility information storage unit 104 stores information on the positional relationship of cars in the elevator hall, information on the position of the entrance to the elevator hall, information on the installation position of the destination floor registration device, the number of cars, the passage width of the elevator hall, etc. Be done. The waiting people evaluation function generation means 105 generates a function based on the waiting people for each car based on the entrance to the elevator hall, the destination floor registration device, and the positional relationship of each car. This function has a large value as the number of people waiting increases. The details will be described later in detail with reference to FIG. The waiting people evaluation calculation means 106 evaluates the number of waiting people from the waiting people evaluation function of each car generated by the waiting people evaluation function evaluation calculation means 106 and the waiting people of each car counted by the waiting number counting means 103 for each machine. Calculate the value. The movement line dependency relation calculation means 107 obtains information on the positional relationship of the car stored in the facility information storage means 104, information on the position of the entrance to the elevator hall, and information on the installation position of the destination floor registration device to the elevator hall. From each inlet, the dependency of the flow line to each car in the elevator hall is calculated. For example, in the case of FIG. 1, when viewed from the entrance to the elevator hall where the destination floor registration device 4A is installed, 3B (No. B) needs to pass in front of 3A (No. A) and 3H (H). . Such an order or distance of proximity from the entrance to each elevator hall is calculated. The waiting time evaluation value calculation means 108 evaluates the waiting time for the newly registered destination floor call based on the position of each car managed by the hall / car information management means 102 and the status of calls received by each car. Calculate The other evaluation value calculation means 109 calculates the degree of congestion of each car managed by the hall / car information management means 102, the estimated value of the boarding time, and the like as other evaluation values. The flow line influence evaluation value calculation means 110 calculates the flow line influence evaluation value from the dependency between the waiting people evaluation value calculated by the waiting people evaluation value calculation means 106 and the flow line calculated by the flow line dependency relation 107. Calculate Here, the flow line influence evaluation value is from the entrance of each elevator hall when the destination floor call newly registered in the vicinity of the entrance to any elevator hall or inside the elevator hall is assigned to any car. The influence of other passengers on the flow line is evaluated, and the details will be described in detail later with reference to FIGS. 2 and 3. Allocation control means 111 calculates a comprehensive evaluation value from each evaluation value calculated by waiting time evaluation value calculation means 108, other evaluation value calculation means 109, and flow line influence evaluation value calculation means 110 for each car. , Assign to the car with the best evaluation value. As a result, the waiting time of each elevator is optimized so that the waiting time is short and the flow of passengers is secured regardless of the entrance of any elevator hall. Coexistence of is possible.

  FIG. 2 shows a calculation example of the flow line influence evaluation value in FIG. FIG. 2 shows an example of group management by eight elevators, in which the arrangement of the cars is a facing arrangement where four units face each other. There are also three entrances to the elevator hall. The movement line influence evaluation value calculation means 108 calculates a movement line influence evaluation value when tentatively allocated to each elevator. Now, it is assumed that the destination floor call is registered in the destination floor registration device 4A and tentatively assigned to 3B (the B car) (the passenger at this time is 5A).

  FIG. 3 shows the flow of passengers from the entrance to each elevator hall at this time. As shown in the figure, when the temporary assignment is performed to the B-th car, passengers waiting between the 3B (B-th B) and 3G (the G-th) may generate passengers whose flow lines are blocked. Therefore, the flow line influence evaluation value calculation means 108 evaluates, as a flow line influence evaluation value, the linear sum of the waiting people evaluation value of the car passing when moving from the entrance to each elevator hall to each car. When passenger 5A1 in the figure goes to 3A (A), it is affected only by 3A (A) and 3H (H), but when 3C (C), 3A (A) 3) (3) (B), 3) (G), 3) (3) (H). Similarly, when passenger 5B goes to 3B (B), it is affected only by 3B (B) and 3G (G) waiting customers, but when 3B (A) goes to 3A (A) Affected by customers waiting for A), 3B (B), 3G (G) and 3H (H).

  Therefore, when tentatively assigned to each car, the linear relationship between the evaluation value of the number of people waiting for the passing car when moving from the entrance to all elevator halls to each car is specified as the flow line influence evaluation value. If the number of customers waiting in the car is large and the flow line is likely to be blocked, the flow line impact evaluation value becomes large (bad), so for elevators that close the flow line, a new destination floor call Is less likely to be assigned.

  FIG. 4 shows an example of the waiting number evaluation function generated by the waiting number evaluation function generation means 105. In the example of the figure, the waiting number evaluation function is configured to be a small constant value when the number of waiting persons is equal to or less than Pth, and to be a large value when Pth is exceeded. Here, Pth is a value determined by the passage width and the positional relationship in the elevator hall. For example, if the elevator hall is narrow, or if you do not want to increase the number of customers waiting for a car, such as a car near the entrance to the elevator hall, Pth is set small. As shown in the example in the figure, by configuring the waiting people evaluation function so that the waiting people evaluation value becomes larger when Pth is exceeded, the influence on the flow lines of the passengers in the elevator hall is small when the waiting people are small. Since it is small and the waiting people evaluation value is small, the flow line influence evaluation value is also small. Thus, new destination floor calls are more likely to be assigned to cars that are less likely to affect the flow of passengers in the elevator hall. In the example shown in FIG. 4, the width is determined depending on the passage width and the positional relationship in the elevator hall, but Pth may be increased as the arrival of a car approaches. In this case, there is a possibility that passengers may collect in the narrow elevator hall or near the entrance to the elevator hall, but since the elevator arrives immediately, there is almost no influence of the obstruction of the flow line to other passengers, improving the operation efficiency. it can. According to the elevator group management system of the embodiment as described above, it is calculated based on the evaluation value of the number of waiting people of the passing car when moving from the entrance to each elevator hall to each car when allocating to each car. Since the assignment is performed using the flow line influence evaluation value, the passenger's flow line can be secured regardless of the entrance to the elevator hall, and as a result, the passenger's flow line can be secured and high operation efficiency can be achieved.

  In the second embodiment, a waiting person evaluation function is generated based on the use frequency of the destination floor registration device to secure a flow line in accordance with the inflow of passengers into the elevator hall. FIG. 5 shows an elevator group management system according to another embodiment of the present invention. The same reference numerals as in the previous embodiment shown in FIG. 1 denote the same parts, and a detailed description thereof will be omitted. The hall entrance use frequency learning unit 112 learns the use frequency for each entrance to the elevator hall. Specifically, the frequency of use of the destination floor registration device installed near the entrance to each elevator hall is learned for each time zone and characteristics of traffic conditions (such as work, lunch, normal, etc.). The waiting people evaluation function generation means 105 generates a waiting people evaluation function using not only the facility information stored in the facility information storage means 104 but also the learning result of the use frequency for each hall entrance.

  FIG. 6 shows an example of the waiting number evaluation function in the present embodiment. As shown in the figure, Pth is a large value for a car near the entrance to the elevator hall which is not used frequently. At the entrance to the elevator hall, which is infrequently used, there is no need to secure a flow line for many people, so the increase in the number of customers does not have a major impact. On the other hand, for a car near the entrance to the elevator hall which is frequently used, Pth is set to a small value in order to secure a flow line for many people.

  In the present embodiment, the configuration of the waiting people evaluation function is changed according to the usage frequency for each entrance to the elevator hall, but the linear result of the calculation result of the waiting people evaluation value calculation means in the flow line influence evaluation value calculation means 110 Alternatively, weighting may be performed according to the frequency of use. For example, the weight is increased for use from the frequently used inlet, and the weight is decreased for use from the low used inlet. As a result, only a minimum flow line can be secured for use from the low-use entrance.

  As in the present embodiment, by adjusting the waiting people evaluation function according to the usage frequency for each entrance to the elevator hall, it is possible to secure the passenger's flow line according to the actual usage of the elevator hall user.
