Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a group management device for an elevator having a wheelchair-accessible car.

In recent years, 1-2 out of multiple baskets (4-8)
The platforms are used as wheelchair baskets, and these are operated in groups. In this case, in addition to the hall button for registering a general hall call, a dedicated hall button for registering a wheelchair-only hall call is installed at the hall. Furthermore, in addition to the destination button for registering a general car call, a dedicated destination button for registering a wheelchair-specific car call is installed inside the wheelchair-accessible car. When a dedicated hall call or a dedicated car call is registered, the wheelchair-compatible car is released from group management and is made to respond to the already registered general car call, dedicated hall call, and dedicated car call.

However, the following problems occur along with this.

(a) By registering a dedicated call, the corresponding car is released from group management, so the assignment to the hall call that was already assigned to it is canceled. Therefore, another car is newly assigned to this hall call, but in this case, there is often a long waiting time for that hall call.

(b) When a car is assigned to a landing call, an assignment forecast is given for that landing (which also doubles as the normal arrival forecast light), but if the assignment changes as mentioned in (a) above, the assignment forecast must also be changed. Waiting customers become confused and irritated.

(c) The above (a) and (b) are problems that general passengers experience when a wheelchair user registers a special call.
If it's a small amount, it should be tolerated. However, if general customers frequently register dedicated calls as a prank, the frequency of the above problems (a) and (b) will increase, causing great inconvenience to other general customers. .

This invention is intended to improve the above-mentioned problems, and when a wheelchair-only hall call is registered, the processing of the already assigned general hall call is handled rationally,
To provide a group management device for wheelchair-use elevators, which allows both general customers and wheelchair users to obtain harmonious service.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 5.

In Figure 1, 1 to 6 are floors 1st to 6th, and a is 3.
Car No. 1 is ascending on floor 3, b is car No. 2 is descending on floor 4, c is car No. 3 is ascending floor 1, and 4a is the car on the 4th floor assigned to car a. 6ca is the 6th floor car call registered with car a, 1cb is the 1st floor car call registered with car b, 2b and 3b are the 2nd and 3rd floor downbound calls assigned to car b. 2cc, 3cc, and 6cc are car calls on the 2nd, 3rd, and 6th floors registered with car c, and 5x is a down-bound call registered on the 5th floor. Note that car a is a wheelchair-accessible car.

In FIG. 2, 11 to 13 are the control devices of cars 1 to 3 that control the cars a to c, and 11a to 13a are the outputs of the control devices 11 to 13, respectively, for cars a to c.
c. Each car status signal indicating the car position, car call, running, stopping, deceleration, door open, door closed, etc.; 14 is a signal issued in response to a general hall call being registered; 15 is a dedicated signal. When a hall call is registered, a signal is issued in response to the registration, 16 is a group management device composed of electronic computers such as a microcomputer, 16A is a central processing unit (hereinafter referred to as CPU),
16B is a memory for storing programs, fixed value data, and calculation result data; 16c is an input device forming a converter for taking input signals into the CPU 16A; and 16D is for outputting output signals from the CPU 16A to the outside. Output devices 17a to 17c constituting the converter are the outputs of the group management device 16, and output signals 18 and 18 are respectively assigned to cars a to c.
Similarly, signals a to 18c are forecast signals.

20-23 in Figure 3, 22A-22I in Figure 4
and 23A to 23K in FIG. 5 are the operating procedures of the program of the group management device 16, respectively.

Next, the operation of this embodiment will be explained.

Assume now that the states of cars a to c, their assigned hall calls, and car calls are as shown in FIG. 1, and that a dedicated down call 5x for the 5th floor has been registered.

These car states and call states are input to the input device 16c of the group management device 16 as individual car state signals 11a to 13a, a general hall call signal 14, and a dedicated hall call signal 15. These signals are
The data is taken into the CPU 16A, processed according to the procedure shown in FIGS. 3 to 5 according to the program stored in the memory 16B, and outputted from the output device 16D to each of the control devices 11 to 13.

In step 20, it is determined whether there is an unallocated private hall call, and if there is not, it is determined in step 21 whether there is an unallocated general hall call, and if there is no unallocated general hall call, the process ends. If there is an unallocated general hall call, well-known allocation/forecast calculations are performed in step 22. If there is an unassigned dedicated landing call in step 20, proceed to step 23.
The process proceeds to , and performs calculations to allocate and forecast the corresponding car to the dedicated hall call. The above is a general flow of operation.

Now, suppose that one unallocated hall call is selected in step 22A of step 22, and this is the up call 4a for the fourth floor. In step 22B, if car a is temporarily assigned to the up call 4a on the fourth floor, the time expected for car a to arrive at that floor, ie, the expected arrival time, is calculated. Step 2
2C similarly calculates the expected arrival time when car b is assigned. In step 22D, the expected arrival time when car c is assigned is similarly calculated. Carts a-b in step 22E
The expected arrival times of the cars are compared, and in step 22F, the unallocated hall call is actually allocated to the shortest car. If it is car a, an allocation signal 17a and a forecast signal 18a are issued. Now, 4th floor 4 1
The warning light at the landing of car No. 1 lights up, predicting that car A has been assigned. In step 22G, determine the surrounding conditions that require canceling the assigned call 4a on the fourth floor, and if there are no such conditions, proceed to step 2.
At 2H, the allocation signal 17a and the forecast signal 18a are held. If the cancellation condition exists, the assignment signal 17a and forecast signal 18a will no longer be emitted in step 22I. In other words, the assignment and forecast will be changed to another car.

Next, in step 23A of step 23, one unallocated dedicated hall call is selected. Assume that this is the down call 5x on the 5th floor. In step 23B, it is determined whether wheelchair-accessible car a has already been assigned to a general hall call. Since car a has already been assigned to the up call 4a on the fourth floor, the process advances to step 23C. After car a responds to the fourth floor up call 4a in step 23C, the expected final car call (in this case 6
The predicted time A (hereinafter referred to as service completion time) until responding to the floor car call 6ca is calculated. This calculation is performed assuming, for example, that the time required for one stop is 10 seconds, and the travel time for each floor is 2 seconds, then the service completion time for car a is A = 10 + 2 x 3 =
Calculated as 16 seconds. Next, in step 23D, the expected arrival time B from the position at the time of service completion until responding to the down call 5x on the 5th floor is calculated. In this case B
It is calculated as =10+2=12 seconds. A+ in step 23E
The value of B is compared with a predetermined value C. In this case, if C = 40 seconds, A + B = 16 + 12 = 28
<40, and at the time of this calculation, it is decided not to cancel the allocation forecast for the up-call 4a on the fourth floor that has already been allocated, but to hold it. Then, the process proceeds to step 23F, where the forecast signal for the corresponding landing of car a, that is, the forecast signal 18a for the downbound call 5x on the 5th floor is issued, and the downbound forecast light is turned on. In step 23G, allocation to general hall calls is subsequently restricted. That is, after the 5th floor dedicated hall call 5x is predicted, only the previously assigned 4th floor up call 4a and 6th floor car call 6ca will be answered. In step 23H, it is determined whether the service for the general hall call has been completed.
In this case, when the up call 4a on the fourth floor is answered, the service is completed, and the process proceeds to step 23I. Steps 23F to 23H can be repeated until the service is completed. In step 23I, an assignment signal 17a to the dedicated hall call 5x is issued, and thereafter the car a responds to the car call 6ca on the 6th floor and the downbound call 5x on the 5th floor. When the car a responds to the 5th floor down call 5x, the assignment signal 17a and the forecast signal 18a disappear in step 23J, the 5th floor down call 5x is canceled, and the forecast light is turned off.

Next, in step 23E, if the value of A+B is quite large, for example 60 seconds, then A+B=60
>40, the process advances to step 23K, and the general hall call allocation forecast is canceled. That is, the assignment of the fourth floor up call 4a is canceled and reallocated to the other cars b and c. The reassignment operation is well known and the details will be omitted. After that, proceed to steps 23F to 23H, and since there is no general hall call assignment, proceed to step 23.
Proceed to I. In other words, car a is on the 4th floor and has an inbound call of 4.
Instead of responding to the car call 6ca on the 6th floor, the user responds to the outbound call 5x on the 5th floor.

As explained above, the present invention is an elevator having a wheelchair-use car that responds to a wheelchair-only hall call, and when a dedicated hall call is registered, if the wheelchair-use car is assigned to a general hall call, the It is determined whether the allocation is to be released or retained based on predetermined conditions, and when the assignment is released, it is assigned to a car other than the wheelchair-use car, the wheelchair-use car is made to respond to a dedicated hall call, and when it is held, the wheelchair-use car is allocated to a car other than the wheelchair-use car. After the car responds to a general hall call, it responds to a dedicated hall call.

As a result, the possibility of canceling the general hall call assignment due to the registration of a dedicated hall call is drastically reduced, so that inconvenience to both general passengers and wheelchair users can be eliminated.
