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

  FIG. 1 is an overall configuration diagram of an elevator group management system showing an embodiment of the present invention. In FIG. 1, the elevator group management system is a destination floor reservation type group management system in which a destination floor is registered at the entrance of the elevator hall, its vicinity, or the entrance of a building, and a car is assigned according to the destination floor. . Here, for simplicity of explanation, an example of group management for two elevators is shown, and the elevator group management system controls two elevator cars 3A (No. A), 3B (No. B), and each elevator No. Device 2A (Control device for Unit A), 2B (Control device for Unit B), and a group management control device 1 that collectively manages two cars. The group management control device 1 includes destination floor registration devices 5A and 5B. Connected to. In addition, in FIG. 1, the situation of the car landing on the first floor (lobby floor) is shown (other floors are omitted).

  The destination floor registration devices 5A and 5B are arranged on the first floor, and the user registers the destination floor with a numeric keypad and creates an elevator call. That is, the destination floor registration devices 5A and 5B are installed in an elevator hall where a plurality of elevators are arranged, and register information including the user's destination floor as destination floor information in response to a user's operation. At the same time, car information (for example, car name) that identifies a car of any one of the elevators is displayed. Destination floor registration device The elevator usage using the destination floor registration devices 5A and 5B is as follows.

(1) A user on the first floor registers a destination floor with the destination floor registration device 5A or 5B.
(2) The group management control device 1 assigns a car serving the destination floor to the registered destination floor.
(3) The car name of the assigned car is displayed on the destination floor registration device 5A or 5B.
(4) The user sees it, goes to the displayed car location, and waits for the arrival of the car before that.
(5) When the car arrives, the destination floor is already assigned to the car, and the user can reach the target floor without registering the destination floor in the car.

  In the destination floor reservation type group management system, a car can be assigned to each registered destination floor, so that a plurality of cars can be assigned according to the destination floor. For example, two groups of a user group 4A assigned to Unit A and a user group 4B assigned to Unit B are waiting in front of two elevators.

  Details of the group management control device 1 will be described below. The group management control device 1 is a computer device provided with information processing resources such as a CPU (Central Processing Unit), a memory, and an input / output interface, for example, and various memories and CPUs to be accessed by the CPU are stored in the memory. Various calculation units to be started are stored. At this time, the group management control device 1 assigns the elevator car of any of the plurality of elevators to the user based on the destination floor information registered in the destination floor registration device 5A or 5B. It has a function of generating a control command for driving the assigned elevator car to the user's elevator hall and outputting the generated control command to the control devices 2A and 2B of each elevator. The control devices 2A and 2B of each elevator control the operation of each elevator car according to the control command, and state information indicating the operation state of each elevator car (the position and direction of the car, the number of passengers in the car) And the like) function as an elevator control device that outputs to the group management control device 1.

  Specifically, the data input / output / storage unit 101 inputs information on the control devices of each car, information on the car landing on each floor and information on each car, and controls the control commands for each car control device and on each device on the landing. Output information. At this time, the data input / output / storage unit 101 stores necessary information among input information and output information.

  The state information storage unit 102 for each car / each destination floor call is based on the information from the data input / output / storage unit 101, the position and direction of each car, the number of passengers in the car, the assigned destination floor, and the call for each destination floor call. Memorize numbers.

  The estimated arrival time calculation unit 103 predicts the arrival of each car on each floor from the information stored in the state information storage unit 102 of each car / each destination floor call based on the position and direction of each car, information on the assigned destination floor, and the like. Calculate time. At this time, the estimated arrival time calculation unit 103 calculates the estimated arrival time at which each elevator car arrives at each elevator platform based on the state information of each elevator.

  The distance data storage unit 104 from the hall entrance stores distance data indicating the distance from the hall entrance on each floor, for example, an elevator hall entrance (near the installation location of the destination floor registration device) to the hall of each car. For example, Unit A on the first floor (lobby floor) stores 10 m of distance data indicating the distance from the entrance to the A platform, and Unit B indicates the distance from the entrance to the B platform. Data is stored as 15m. The distance data does not necessarily have to be a physical distance value, and may be stored in the order of the proximity from the landing entrance to the landing of each car. These data are set when the group management control device 1 is shipped from the factory, when it is installed in a building, at the time of maintenance before the actual operation of the elevator facility, and the like.

  The boarding capacity storage unit 105 stores information on boarding capacity (for example, 24 persons) of each car. The boarding capacity may be a value obtained by dividing the loading capacity by the assumed weight per person (for example, 24 persons obtained by dividing the loading capacity of 1600 kg by the assumed weight per person 65 kg). Considering availability, a value obtained by multiplying a predetermined ratio (for example, 19 people obtained by multiplying the above 24 people by 0.8) may be used.

  The waiting number allowable value calculation unit 106 determines, for each car, from distance data indicating the distance from the hall entrance (installation position of the destination floor registration device) of each car to each car hall and the passenger capacity of each car. Calculate the waiting value tolerance. That is, the waiting number allowable value calculation unit 106 calculates the waiting number allowable value for each car according to the landing and car position conditions. At this time, when the waiting number allowable value calculation unit 106 calculates the waiting number allowable value set for each elevator for each floor, the waiting number allowable value calculation unit 106 calculates the waiting number allowable value for each elevator from the installation position of the destination floor registration devices 5A and 5B. The closer the distance to the elevator hall of each elevator is, the smaller the value is calculated. This adjusts the waiting number of each car.

  Details of the waiting number allowable value calculation will be described later in detail with reference to FIG. It is not always necessary to calculate the allowable number of waiters, but it is calculated at the time of factory shipment of the group management device, installation to the building, before the actual operation of the elevator equipment, and after maintenance, etc. Thereafter, the value may be stored and used.

  The waiting number allowable value review unit 107 reviews the waiting number allowable value based on the waiting number allowable value of each floor / car and the estimated arrival time of each floor / car. That is, the waiting number allowable value review unit 107 performs a review using the estimated arrival time of the car with respect to the waiting number allowable value for each car set according to the landing and car position conditions.

  A review of the waiting number tolerance is carried out regularly. Details thereof will be described later in detail with reference to FIGS.

  The waiting number counting unit 108 counts the waiting number for each car on each floor from the registered number of destination floor calls and information on the assigned car of each destination floor call. In the destination floor reservation type group management system, each user registers the destination floor in order to check the assigned number of machines. The number of people waiting for each car is determined based on the number of registrations on the destination floor and the information on the assigned number. Can be calculated. At this time, if the information including the new user's destination floor is registered as new destination floor information in the destination floor registration device 5A or 5B, the waiting number counting unit 108 counts the number of registrations of the destination floor by the new user. And the number of people waiting for each elevator car on each floor is counted from the number of people assigned to each elevator car assigned according to the destination floor of the new user.

  The assignable car selection unit 109 selects a car that can be assigned from the waiting value allowable value of each car and the waiting person count value of each car. For example, a car having a waiting number counting value smaller than the waiting number allowable value is selected as an assignable car. As a result, a car that has already waited more than the permissible value will not be assigned, so there will be no increase in the number of waiters unless the permissible value for the waiter is reviewed. It is possible to prevent the flow of other cage users from being obstructed by this group.

  The assigned evaluation value calculation unit 110 for each car for a new call calculates an evaluation value for the assignment to a newly registered destination floor call for each car determined to be assignable. The assigned evaluation value is calculated from information such as the position and direction of each elevator, the number of passengers in the car, the assigned destination floor, the number of calls for each destination floor, the number of registrations, and the estimated arrival time.

  The assigned car selection unit 111 selects a car having the best evaluation value as an assigned car based on the calculated assigned evaluation value. At this time, at least one of the assignable car selection unit 109 and the assigned car selection unit 111 compares the waiting number calculated by the waiting number counting unit 108 with the waiting number allowable value calculated by the waiting number allowable value calculation unit 106. As a car selection unit for selecting an elevator car to be assigned to a new user based on the new destination floor information (information indicating the newly registered destination floor) Function.

  Further, the data input / output / storage unit 101 inputs state information of the elevator car selected by the car selection unit from the control devices 2A and 2B of each elevator car, and the elevator selected based on the input state information. Functions as a control command generation unit that generates a control command for driving the passenger car to the elevator landing of a new user and outputs the generated control command to the control devices 2A and 2B of each elevator. The information for identifying the elevator car selected by the department is generated as car information (for example, car name) for identifying the elevator car assigned to the new user, and the generated car information is the destination. It functions as an information generation unit that outputs to the floor registration device 5A or 5B. As a result, the new user sees the car information (car name) displayed on the destination floor registration device 5A or 5B, goes to the displayed car location, and waits for the arrival of the car before that. Can do.

  FIG. 2 is a schematic diagram for explaining the setting of the waiting number allowable value in the elevator hall by the area of the region. FIG. 2 shows an example of group management by six elevators (A-F to F-No.), In which six cars are in a face-to-face arrangement such that three cars face each other.

  FIG. 2 shows a cross section obtained by horizontally cutting the elevator hall, the vicinity of its entrance, and the hoistway of each elevator. The hoistway of Unit A is an area A01, and similarly, the hoistway area from Unit B to Unit F is arranged clockwise. The elevator hall is the entire area A02, and the embodiment assumes a situation where the hall area is narrower than usual. The destination floor registration devices 5A and 5B are separately set on the left and right sides of the elevator hall entrance.

  The elevator user registers his / her destination floor (for example, the 12th floor) with the destination floor registration device 5A or 5B at the entrance of the elevator hall, and confirms the assigned number (for example, the number D) displayed there. Enter the elevator hall area A02 and wait for the arrival of the car in front of the assigned Unit D.

  In the case where the elevator hall area is small, if a large number of users already assigned to Unit F are waiting, the user assigned to Unit D needs to bypass this. When there is a lot of traffic, such as at peak attendance, there are many waiting customers in Units A and B, and the users assigned to Unit D spend time while avoiding these waiting customers. It will finally reach there. Therefore, if Unit D arrives and departs during this time, this user must re-register the destination floor and go to the newly assigned unit there, and it takes a long time to get on the elevator. Cost. For the group management control device 1 as well, another elevator must be assigned to the user who was originally transported by the Unit D, and the transportation efficiency of the entire building deteriorates. The worst case is when both the waiters of Unit A and Unit F are full and waiting. In this case, the entrance of the elevator hall is blocked, so the units behind that (Units B, C, D, E) The users assigned to) cannot get there, and there is a risk that a large number of users will accumulate near the entrance.

  In FIG. 2, the waiting number allowable value of each elevator is schematically represented by the area of a rectangular area surrounded by a solid line in front of each elevator. The allowable waiting number for Unit A is expressed as the area of area A03. Similarly, Unit B is area A04, Unit C is area A05, Unit D is area A06, Unit E is area A07, and Unit F is area A08. expressed. Further, the area of the region A09 surrounded by the alternate long and short dash line schematically represents the passenger capacity of each elevator.

  The waiting number allowable value of each unit represented by the solid line areas A03 to A08 is set so that the value becomes smaller as the distance from the elevator hall entrance to the landing of each unit is shorter (represented by a one-dot chain line). The solid line area is smaller than the boarding capacity area A09.

  Dotted lines X and Y represent setting characteristics for the waiting number allowable value. That is, since the areas of the regions A03 to A05 and the regions A08 to A06 become smaller as they move away from the elevator hall entrance, the dotted lines X and Y approach each other as they move away from the elevator hall entrance, and show the characteristic of connecting the intersections at the corners of the region A02. . From the characteristics of the dotted lines X and Y, the closer to the elevator hall entrance (for example, No. A), the number of people waiting will be reduced, and users assigned to the elevators behind the elevator hall (for example, No. C and D) It is possible to ensure the flow line with respect to. As a result, even during times of congestion, each user can quickly move to the location of the assigned elevator.

  Since Unit A carries a smaller number of passengers than the number of passengers on board, it seems that the transportation efficiency is lowered. However, in cases where the elevator hall is narrow, it is worse in terms of efficiency that it is necessary to carry a new unit without getting on board. Become. In other words, because the car could not be boarded, the first car was uselessly stopped, the new car had to be serviced again, and the user had to register the destination floor twice.

  Moreover, although the shape of the elevator hall and the arrangement of the elevators are various, the determination of the waiting number allowable value may be made according to the position condition of the elevator in the elevator hall, and at least one of the plurality of elevators One is different from the other, and the impact on operation efficiency due to congestion is improved.

As a method of calculating the waiting number allowable value, a method of directly determining the allowable value depending on the distance from the elevator hall entrance of each elevator unit or a method of using a coefficient corresponding to the distance as in the following equation may be adopted. it can.
Waiting number tolerance = distance factor (L) x boarding capacity (1)
Here, the distance coefficient is determined by the distance L between the elevator hall entrance and the elevator car, and takes a value of 0 or more and 1 or less. Further, it is not always necessary to obtain from the physical distance, and the order determined by the square value of the distance or the distance may be used. For example, the coefficient value may be determined in advance by the rank (N), and the allowable value may be obtained by the following rank coefficient.
Waiting number tolerance = rank factor (N) of the elevator x boarding capacity (2)

  In any case, by determining the allowable number of elevator waiters in relation to the distance from the elevator hall entrance of each elevator or its position, the number of elevator waiters can be limited accordingly. .

  Furthermore, when the location of the elevator hall entrance varies depending on the floor, the distance between each elevator and the elevator hall entrance varies depending on the floor, so it is based on the distance from the elevator hall entrance of each elevator according to the floor. Then, it is sufficient to determine the waiting number allowable value.

  FIG. 3 is a schematic diagram for explaining the review of the waiting number allowable value in the elevator hall by the area of the region. In FIG. 3, in the case where the elevator hall area is narrow, when the waiting number allowable value is set along the dotted lines X and Y, the number of waiting passengers is reduced as the elevator is closer to the elevator hall entrance. It is possible to ensure a flow line for the user assigned to the elevator at the back of the hall. As a result, even during times of congestion, each user can quickly move to the location of the assigned elevator.

  However, the elevator number close to the entrance of the elevator hall, for example, the F number, has a waiting number allowable value smaller than the area A09 of the passenger capacity as in the area A08 in order to suppress the number of waiting passengers. As a result, Unit F starts with a smaller number of passengers than the number of passengers that can be in the car, and transportation efficiency decreases.

  On the other hand, in order to increase the transportation efficiency, the waiting number allowable value for the F car is changed from the area A08 to the area A10 on the condition that the time until the arrival of the elevator car near the elevator hall, for example, the F car is short. If it is set to (region corresponding to the passenger capacity), there may be a situation where the waiting passengers obstruct the flow line near the entrance of the elevator hall. However, if the time until the arrival of Unit F is short, the obstruction of the traffic line is temporary, and if the elevator arrives and the waiting passenger starts to board, It will be resolved.

  FIG. 4 is a flowchart for explaining processing of the waiting number allowable value review unit. In FIG. 4, the waiting number allowable value review unit 107 determines whether or not a predetermined time has elapsed since the previous process (ST101). When a negative determination result is obtained in step ST101, the waiting number allowable value review unit 107 repeats this process until a predetermined time has elapsed. When a positive determination result is obtained in step ST101, that is, when a predetermined time has elapsed, the waiting number allowable value review unit 107 executes a loop process for reviewing the waiting number allowable value for each elevator (ST102). ). This loop process is executed for all the units in order from the first unit to the last unit while changing the value of k.

  The waiting number allowable value review unit 107 compares the estimated arrival time at the call generation floor of the k-th unit with a predetermined threshold Tth for each k-th unit in order to review the allowable number-of-waiting value. It is determined whether or not the estimated arrival time at the call generation floor of the second car is smaller than the threshold value Tth (ST103), and at step ST103, the predicted arrival time at the call generation floor of the k-th unit is smaller (shorter) than the threshold value Tth. ), The allowable number of passengers waiting for the kth car on the floor where the call is generated is reviewed, and the passenger capacity of the kth car is set as the allowable number of waiting persons (ST104). Thereafter, the process proceeds to step ST105, while step ST103 is performed. If it is determined that the estimated arrival time of the k-th call to the floor where the call is generated is larger (longer) than the threshold value Tth, the process of step ST105 is performed without reconsidering the waiting number allowable value of the k-th number. Row.

  Next, the waiting number allowable value review unit 107 determines whether or not the loop processing of the unit has been completed (ST105). If the loop processing has not been completed, the value of k is changed, and all of them are sequentially performed until the final unit. The process of steps ST103 to ST105 is repeated for the car No. (ST106), and when the loop process for all elevator cars is completed, the process in this routine is terminated.

  Note that in step ST104, the waiting number allowable value review unit 107 calculates the waiting number allowable value calculation unit 106 on the condition that each elevator approaches the landing of each elevator based on the calculation result of the estimated arrival time calculation unit 103. Is corrected to a large value (for example, boarding capacity), and the corrected waiting number allowable value is output to the assignable car selection unit 109. The assignable car selection unit 109 compares the waiting number allowable value corrected by the waiting number allowable value review unit 107 with the waiting number counted by the waiting number counting unit 108. At this time, for example, as shown in FIG. 3, on the condition that the time until arrival of Unit F is short, the waiting number allowable value for Unit F is corrected from region A08 to region A10 (region corresponding to the passenger capacity). can do. In this case, since the time until the arrival of Unit F is short, the obstruction of the traffic line becomes temporary, and if the elevator (No. F) arrives and the waiting passenger starts to get on, the obstruction of this traffic line is eliminated. Thus, the operation efficiency of the elevator (No. F) can be improved.

  Here, in FIG. 4, for each elevator, the estimated arrival time at the call generation floor and the predetermined threshold value Tth are compared only once. The permissible value may be reviewed. In this case, the waiting number allowable value is set to increase as the estimated arrival time at the call generation floor becomes shorter.

  FIG. 5 is a flowchart for explaining the assignment process. In FIG. 5, the CPU that controls the entire group management control device 1 determines whether or not a destination floor call is newly registered based on information from the destination floor registration devices 5A and 5B (ST201). If a negative determination result is obtained in step ST201, the CPU repeats this process until a new destination floor call is registered. If a positive determination result is obtained in step ST201, whether or not each elevator can be assigned. If it is possible, a loop process for calculating the evaluation value Φ (k) is started (ST202). This loop process is executed for all the units in order from the first unit to the last unit while changing the value of k.

  For each k-unit, the CPU compares the waiting number of the k-th unit at the call generation floor with the allowable waiting number of the k-th unit at the call-generation level, and the waiting number of the k-th unit at the call generation floor is When it is determined whether or not the waiting number for the k-th unit on the call generation floor is equal to or greater than the allowable number of waiting persons (ST203), and a positive determination result is obtained in step ST203, that is, the waiting number is larger than the allowable number of waiting persons , K is determined to be unassignable (ST204). When it is determined that the assignment is impossible, the CPU does not calculate the evaluation value of that unit (unit k) and removes unit k from the allocation target for the new call. As a result, the maximum waiting number of each unit is limited to an allowable value or less, and the waiting state is controlled as shown in the solid line areas A03 to A08 in FIGS. Note that the number of people waiting on each floor of each unit is estimated from the number of destination floor registrations.

  On the other hand, if a negative determination result is obtained in step ST203, that is, if the waiting number is smaller than the waiting number allowable value, the CPU provisionally allocates a new destination floor call to k-th unit (ST205), and assigns to k-th unit. Evaluation value Φ (k) is calculated (ST206).

  Next, the CPU determines whether or not the loop processing of the number machine has been completed (ST207). If the loop processing has not been completed, the value of k is changed, and all the numbers are sequentially ordered until the last number machine. Steps ST203 to ST207 are repeated (ST208), and when the loop processing for all elevators is completed, the elevator having the smallest assigned evaluation value Φ (k) is determined as the assigned car for the new destination floor call (ST209). ), The process in this routine is terminated.

  At this time, the assigned evaluation value calculation unit 110 and the assigned car selection unit 111 for each car for a new call have a waiting number counted by the waiting number counting unit 108 larger than the waiting number allowable value calculated by the waiting number allowable value calculation unit 106. When it is small, the evaluation value is calculated for each elevator, and the elevator car that minimizes the value among the calculated evaluation values functions as a car selection unit that selects the elevator car to be assigned to a new user. To do.

  Through the processing as described above, the waiting number of each elevator is adjusted and controlled so as to satisfy the waiting number allowable value as defined by the characteristics X and Y as shown in FIG. 2 and FIG. The elevator with the best evaluation value will be assigned.

Furthermore, considering the number of passengers already in the car, if the number of people who can actually get in the car is defined as the “number of people that can get in”, the upper limit of the number of people waiting is What is necessary is just to decide in the smaller one. This can be expressed as:
Maximum number of people waiting = MIN {allowable number of people waiting, number of people who can board} (3)

  Here, MIN is an operation for selecting the minimum value in parentheses. This makes it possible to control the number of waiting persons more appropriately in consideration of both the inside of the car and the waiting situation in the hall. However, in the case of busy working hours, since the boarding is mainly from the lobby floor, the upper limit of the waiting number may be determined by the waiting number allowable value.

  In the flowchart of FIG. 5, when the number of waiting passengers in all elevators is equal to or greater than the waiting passenger allowable value, it is a very severe congestion situation (almost no such case) that is close to the elevator transportation capacity limit. Then, it is sufficient to remove the restriction of the waiting number allowable value and to assign it to a machine with a good assignment evaluation value.

  According to the above-described embodiment, the traffic flow of the passenger can be secured even when the elevator hall is crowded with passengers by performing the allocation based on the waiting number allowable value. That is, it is possible to ensure the traffic lines of passengers when the hall is crowded along the dotted lines X and Y. Further, since the elevator is prevented from leaving by a small number of people by revising the waiting number allowable value based on the arrival time at the elevator hall, the operation efficiency of the elevator can be improved. In addition to selecting the elevator to be assigned according to the waiting number allowance, and when the arrival time to the elevator landing approaches, the restriction on the assignment due to the waiting number allowance is relaxed, ensuring the traffic line of passengers and high operating efficiency. It can be compatible.

  In FIG. 5, it is determined that the allocation is impossible only by comparing the waiting number and the waiting number allowable value. However, when the waiting number allowable value is changed by the waiting number allowable value review unit 107, Only a destination floor call that is the same as a destination floor call that is already held may be assigned. At this time, the assignable car selection unit 109 or the assigned car selection unit 111 determines whether the waiting number allowable value corrected by the waiting number allowable value reviewing unit 107 and the waiting number counted by the waiting number counting unit 108 are new. After selecting the elevator car to be assigned to the user, if the destination floor by the new user is registered in the destination floor registration device 5A or 5B, the destination floor of the selected car and the new On the condition that the destination floor of the user is the same, it functions as a car selection unit for assigning the selected car to a subsequent new user. In this case, the destination floor is not newly increased in the car, so that higher operation efficiency can be maintained.

  Also, if there are more users than can be carried in the first round, a waiting space for the second round will be provided, and a car will be placed so that the traffic line from the waiting area for the second round to the landing can be secured. By allocating, smooth flow can be realized even if traffic demand exceeds expectations in the future.
