[0012]
In FIG. 1, 7 is an upper car zone, 8 is a shared zone, 9 is a lower car zone, and 10 is a main floor zone, which are set as follows.
(1) The upper car dedicated zone 7 is composed of the seventh floor to the tenth floor for each unit.
(2) The common zone 8 is composed of the 2nd basement floor for Unit 1, the 1st to 6th floors and the 1st to 6th floors, the 2nd floor to the 6th floor, the 3rd to 6th floors for the 3rd to 6th floors. Yes.
(3) The lower car exclusive zone 9 is composed of the second floor on the second floor and the second floor on the third and sixth to sixth machines, the first basement and the first floor.
[0013]
(4) The main floor zone 10 is composed of the 1st and 2nd floors of each unit. The 1st floor is the lower car hall (for the 2nd to 6th floors) and the 2nd floor is the upper car hall (for the 7th to 10th floors). It has become.
As a result of the above, two cars for the upper car zone 7 on the first floor will be put into service, two on the second floor, two on the first basement, and one on the second basement.
In FIG. 1, the upper car can be boarded on the second basement floor. In this case, a retreat floor corresponding to the third basement floor (not shown) is provided, and the lower car is retreated below the second basement floor. It is necessary to do so. If there is no evacuation floor, the lower cage can be serviced up to the first basement floor.
[0014]
In FIG. 2, 13 is a landing destination floor registration device installed at a landing and where destination call buttons are arranged, 14 is a working floor indicator that is installed at the landing and displays the working floor of each car, and 15 controls each car. A landing destination floor registration device 13 and a working floor display 14 are connected to each of the control devices. Reference numeral 16 denotes a group management control device that is connected to each vehicle control device 15 and is configured by a computer and that efficiently manages and controls a plurality of cars, and includes the following units.
[0015]
16A is a communication means for communicating information between the respective vehicle control devices 15, 16B is a zone setting means for setting an upper and lower car accessible zone, 16C is a priority setting means for setting an assignment priority of the car, and 16D is an assigned car. 16E is an entry determination means for determining whether or not entry into the common zone 8 is possible so that the upper car and the lower car do not collide, and 16F is for each car according to the calculation result of the assignment determination means 16D. The operation control means 16G outputs an operation command, and 16G is a destination possible floor setting means for setting a destination destination floor of the car.
[0016]
Next, the operation of this embodiment will be described with reference to FIG. It is assumed that the upper and lower car entry zones as shown in FIG. 1 are set in advance by the zone setting means 16B.
When the destination call is registered in the landing destination floor registration device 13 of each floor at step S1, the destination possible floor setting means 16G sets the destination floor of the upper and lower cars according to the zone setting at step S2, and the destination is not possible. The candidate car is calculated by excluding the upper and lower cars. (See (1) below for details)
[0017]
In step S3, the priority setting means 16C calculates an allocation priority for the allocation candidate car (the higher the value, the easier it is to allocate). In the following, an allocation calculation is executed. In this allocation calculation, an evaluation value calculation normally used in group management control is performed. That is, in step S4 and step S5, evaluation values of all the upper and lower cars that are allocation candidates (the smaller the value is, the easier it is to be allocated) are obtained by the sum of the waiting time evaluation value, the full passage evaluation value, the out-of-forecast evaluation value, and the like. . Here, a value obtained by further subtracting the allocation priority is set as a final evaluation value. Then, the car having the smallest evaluation value among the upper and lower cars whose evaluation values are calculated in step S6 is assigned. (See (2) below for details)
[0018]
As a result, the operation control means 16F makes the assigned car respond to the floor where the destination call is registered. Here, step S2 constitutes destination destination floor setting means 16G, step S3 constitutes priority setting means 16C, and steps S4 to S6 constitute allocation determination means 16D.
Next, the destination floor setting operation in step S2 and the allocation priority setting operation in step S3 will be described.
[0019]
(1) Destination floor setting Set destination floors for each floor, direction, and car.
For example, if it is the lower car 4b of No. 4 in FIG. 1 (bound from the first floor landing), the common zone 8 (2nd to 6th floors) can be a destination, and this is set as a destination possible floor. (The 7th floor to the 10th floor are the upper car zone 7, so it cannot be set as a destination floor.)
In the case of the upper car 5a of the fifth car, since both the shared zone 8 and the upper car dedicated zone 7 can be destined, all of these are set as the destination feasible floor.
In this way, the destination possible floor is set based on the zone determined by the zone setting means 16B.
[0020]
Allocation priority setting The allocation priority used for allocation evaluation value calculation is set for each floor, direction, and car. One example will be described with reference to FIG.
FIG. 4 (A) shows the floors in the upper car-only zone 7 and the floors in the common zone 8 for the upper car a and the lower car b (both will be described later). An example of allocation priority in the case where the floor in which both the car 8 and the lower car dedicated zone 9 coexist and the floor in the lower car dedicated zone 9 are each set as the departure floor and both go to the upper car dedicated zone 7 (upward direction). Indicates. FIG. 4B similarly shows an example of the allocation priority for the common zone 8 (upward direction).
[0021]
In addition, the code | symbol showing the allocation priority in FIG. 4 (A) (B) is as follows.
◎: Allocation priority High ○: Allocation priority Medium △: Allocation priority Low ×: Allocation impossible [0022]
In the floor where the common zone 8 and the lower car dedicated zone 9 are mixed (in FIG. 1, the second basement B2F to the first floor 1F), the car in which the common zone 8 is set is an A type car (for example, the basement 1 in FIG. 1). The first car and the second car on the floor), and the car in which the lower car dedicated zone 9 is set is a B type car (for example, the third car to the sixth car on the first basement floor in FIG. 1).
Note that the upper car a of the A type car can enter the basement floor, and the upper car a of the B type car cannot enter the basement floor.
[0023]
In the floor where the common zone 8 and the lower car zone 9 coexist, there are few cars available for the upper car zone 7, so the passengers bound for the upper car zone 7 are concentrated on the specific cars, and the A type car is in service. The situation gets worse. Here, in the floor including the common zone 8, for the passengers destined for the upper car exclusive zone 7, the allocation priority is increased so as to allocate the B type car as much as possible, and the working degree of the A type car is improved. I am doing so.
[0024]
Further, by placing the upper car a for the upper car exclusive zone 7 and the lower car b for the common zone 8, the number of times the car is stopped can be reduced and the working degree can be improved. Here, regarding the destination call from the floor in the shared zone 8 to the floor in the shared zone 8, the allocation priority for the upper car a is lowered to make it difficult to put the upper car a in service in the shared zone 8. I am doing so.
[0025]
In this way, the lower car-only zone 9 and the common zone 8 are set for each floor, not for each floor, and for each of the upper and lower cars a and b. The common zone 8 can be set for some of the upper and lower cars a and b, and the entire floor can be moved without changing.
[0026]
Moreover, since the allocation priority is set according to the landing call generation floor, the destination call, and the upper and lower cars a and b, it is possible to make the service uniform (improve driving efficiency). That is, when the common zone 8 is set as a specific car in the basement floor B1F, B2F or the like that normally sets the lower car dedicated zone 9, the upper car a has to enter the basement floor B1F, B2F. For this reason, the load with respect to a specific cage | basket | car becomes high and the service to another floor may worsen. However, this is avoided by setting the allocation priority.
In the first embodiment, the upper car dedicated zone 7, the shared zone 8, and the lower car dedicated zone 9 are set as shown in FIG. 1, but the present invention is not limited to this. In addition, the setting of these zones 7 to 9 may be made more useful by changing the number of cars for the upper car dedicated zone 7 by setting by reservation or the like according to the time zone.
[0028]
【The invention's effect】
As described above, in the first invention of the present invention, the lower car dedicated zone and the common zone are set for each floor and for each upper and lower car. It is possible to set a common zone in some upper and lower cars, and it is possible to move without changing all floors.
[0029]
In the second invention, since the second floor is set as a common zone and the first floor and the basement floor are set as a lower car exclusive zone and a common zone, all the floors can be moved without changing. it can.
[0030]
Further, in the third invention, when the hall call is registered, the allocation candidate cars for the hall call are calculated from the cars available for service on the floor in the set zone. Can be moved without changing trains, and the most suitable upper and lower cars can be selected.
[0031]
In the fourth invention, the priority for the hall call allocation is calculated, and the allocation car is determined from the allocation candidate cars according to the priority, so that all floors can be transferred without changing. In addition to being able to move, service efficiency can be improved and service can be made uniform.
