Description

TECHNICAL FIELD The present invention relates to an elevator group management control device in a group management elevator system that selects and responds to an optimum elevator car based on destination floor information from a hall. .

[Prior Art] A conventional group management control device of this type is disclosed in, for example, Japanese Patent Laid-Open No. 58-16.
The one shown in Japanese Patent No. 7364 is known. In such a conventional device, for a plurality of elevators with inconsistent service floors, a car that can service both this hall and the destination floor is selected based on the destination floor information from a common hall, and the optimal car It is configured to provide the car as a service car.

In order to allocate the optimum car from the cars that serve both the registered destination floor and the hall, the evaluation value is calculated according to a predetermined procedure, and the car with the highest evaluation value is selected and serviced to the hall.

In such a conventional apparatus, after allocating to a specific car, if a destination floor that cannot be serviced by the allocated car continues to be registered at the hall, another car is allocated.

[Problems to be Solved by the Invention]

As described above, in the conventional control device, when the car that services the hall and the destination floor is once allocated, and then another destination floor is registered from the same hall again, the elevator car that was previously allocated is later allocated. If the registered destination floor cannot be serviced, another elevator car must be assigned at the same landing, which causes a problem that the operation efficiency of the elevator deteriorates.

The present invention has been made in order to solve the above problems, and makes it possible to service an elevator car assigned as early as possible to a destination floor registered later at the same landing. It is an object of the present invention to provide an elevator group management control device that controls the operation, realizes efficient operation of the elevator, and saves energy.

[Means for Solving the Problems]

Elevator group management control device according to the present invention, assigned car selection means for selecting and assigning the optimal car that can service both the hall where the destination floor information was obtained and the registered destination floor, and the already assigned cars Service availability detection means for determining whether or not the destination floor registered later from the same landing can also be serviced, and if the determination result is negative, all destination floors registered again from the same landing can be serviced. An assigned car changing means for selecting a car and instructing the assigned car selecting means to change is provided.

[Action]

The assigned car changing means according to the present invention changes the assigned car so that it can service any of the destination floors if the previously assigned elevator car cannot service the destination floor registered later.

〔Example〕

An embodiment of the present invention will be described below with reference to FIG.
FIG. 1 is a block diagram showing the overall construction of an embodiment of the present invention.

(1) is a hall call button such as a destination floor button installed in the hall, (3) is a well-known assigned car selecting means, and (6) is a well-known car controller. When the hall call button (1) is operated and the destination floor is specified, the destination floor information acquisition means (2) connected to this hall call button (1) registers the destination floor, and the destination floor information is stored. Output to the assigned car selection means (3).

The assigned car selecting means (3) selects the optimum car from the cars that can serve both the hall and the registered destination floor. Then, the car controller (6) is instructed to direct the selected optimum car to the hall.

The output of the destination floor information acquisition means (2) is also input to the service availability detection means (4), and the service availability detection means (4) uses the destination floor where the already assigned car is registered later at the same landing. It has a function to judge whether the service is possible at the same time.

If the service car assigned earlier cannot service the destination floor entered later, the service availability detection means (4)
Instructs the allocation car changing means (5) to change the allocation to the cars that can service all registered destination floors. In this case, an allocation registration command is allocated to the car control device (6) of the newly allocated car and is output via the car selection means (3), and an allocation cancellation command of the car whose allocation is canceled by the allocation change is output. To do.

The normal destination floor information acquisition means (2), the assigned car selection means (3), the service availability detection means (4) and the assigned car change means (5) are composed of a microcomputer (10), which is shown in FIG. A block circuit diagram is shown.

The microcomputer (10) is a central processing unit (CPU)
(10A), a storage device (10B) consisting of a read-only memory for storing programs and fixed-value data and a read-only memory for temporarily storing data such as operation results, and data transmission / reception with the car control device (6) And a conversion device (10D) that is connected to the destination floor button (1) and converts the input / output signal level.

Fig. 3 is a diagram showing the availability of services for group-managed elevators with 6 groups and 10 service floors. It is impossible to service the floors marked with an X in the figure. Is shown. That is, Units A to C are unable to service the 8th to 10th floors.

The operation of the apparatus shown in FIGS. 1 and 2 will be described below in detail with reference to the flowcharts shown in FIGS. 4 and 5.

For the sake of convenience of explanation, a case will be described as an example in which the fifth floor and the ninth floor are registered as the destination floor in the order of riding on the first floor in the group management elevator as shown in FIG.

The flowchart shown in FIG. 4 is started when the destination floor of the hall is registered by the assigned car selection program. First, when the destination floor on the 5th floor is registered at the hall on the 1st floor, step 40
Since the assigned car has not been selected in step 1, the process proceeds to step 403, and the car that is the most suitable car than the cars (A to F in FIG. 3) that can service both the hall (1st floor) and the destination floor (5th floor) Is selected, and the allocation process ends.

9 at the same hall (1st floor) before the next assigned car arrives
When the destination floor of the floor is registered, since the assigned car has already been selected in step 401, the process proceeds to step 402, and the already assigned car is the newly registered destination floor (9
It is judged whether the floor can be serviced. If service is possible, the process is terminated. If service is not possible, the most suitable car is selected from the cars (D to F) that can service both the landing (1st floor) and the newly registered destination floor (9th floor). Then, it is assigned and the processing is completed.

The flowchart shown in FIG. 5 shows an assigned car control program, which is started when the assignment is registered in accordance with the flowchart of FIG. First, when the destination floor on the 5th floor is registered and a car is assigned, it is determined in step 501 that there is only one assigned car. Therefore, the process proceeds to step 506 to assign and register the assigned car to the control device (6) for processing. finish.

Next, when the destination floor on the 9th floor is registered and a new car is assigned, since there are two assigned cars, the process proceeds from step 501 to step 502 and is registered in the first assigned car. It is determined whether or not the car to which the destination floor (fifth floor) is assigned to two cars can be serviced. If the service is possible, the process proceeds to step 503, and it is determined whether the sum of the duration of the first call and the expected arrival time of the second assigned car is within a specified value. If this is within the specified value, the process proceeds to step 504 and the destination floor registered in the first assigned car is set to 2
Change the allocation to the second assigned car and proceed to steps 505 and 506 to instruct the car control device of the relevant car to change the allocation.
Complete the process.

When it is determined in step 502 that the second assigned car cannot service the destination floor registered in the first assigned car, or in step 503, the first call duration and the second assigned car When it is determined that the sum of the estimated arrival time and the arrival time exceeds the specified value, the process proceeds to step 506, the assignment is registered in the car control device of the new assigned car, and the process is terminated.

In the embodiment described above, the destination floor registration on the first floor was described as an example in the case shown in FIG. 3, but the present invention is completely independent of the number of service floors and the number of cars. It can be applied when the destination floor is registered in.

Further, in the above-described embodiment, the sum of the duration of the first call and the expected arrival time of the second assigned car is used as the condition for determining whether or not to change the assignment. The condition is not limited, and other conditions, such as a difference in the estimated arrival times of the two assigned cars and whether or not the first call is waiting for a long time, may be used as the determination condition.

〔The invention's effect〕

As described above, according to the present invention, when it is determined that the already assigned car cannot service the destination floor registered later, the car that can service the hall and all the registered destination floors. Since the car is selected again and the allocation is changed for the selected car, it is not necessary to unnecessarily allocate two or more cars in the same direction at the same landing, and the deterioration of elevator operation efficiency is prevented. There is an effect that can be done.
