Abstract

PURPOSE:To call a desired elevator for a waiting customer by providing a device selecting an elevator at the minimum load state based on a load state judging means and a device allocating the elevator at the minimum load state to the hall call when the selecting device is operated at a platform. CONSTITUTION:When an up-button is pushed at the elevator hall of the fifth floor and a hall call detected signal 2a is inputted to a call registering circuit 3 then a vacancy call detected signal 1a is inputted to the circuit 3 within the fixed interval, the circuit 3 judges it as a vacancy call and inputs a call register signal 3a to a cage weight measuring circuit 4. The circuit 4 checks the weight in the cages of serviceable elevators and detects the lightest cage and temporarily allocates it in the vacancy call registration. When the inner weight of the temporarily allocated cage is one half or below of the maximum load weight, if there is a cage arriving the fifth floor earlier than this cage, it is used for service, if the temporarily allocated cage can arrive earlier, this temporarily allocated cage is used for service at the fifth floor.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an elevator control system, and more particularly to a system for allocating the least loaded car to a hall call.

[Conventional technology]

・When multiple elevators are installed in parallel, it is required to link each elevator and control its operation efficiently. There are various ways to allocate the information, for example, Japanese Patent Publication No. 57-52313 or Japanese Patent Publication No. 5B-56710.
An example of such an elevator group management control device is the one disclosed in the above publication.

[Problem to be solved by the invention]

Now, with the elevator group management control device as mentioned above, it is possible to make elevators respond immediately.
Although it provides excellent service to waiting passengers, some waiting passengers refuse to board the elevator when it appears that there are a large number of passengers. Some waiting customers register for hall calls several times until an elevator with a small number of passengers arrives, which causes a decrease in elevator operation efficiency and worsens the service quality for other users. Was.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an elevator control device that can call a desired elevator to the waiting customer without reducing the operating efficiency of the elevator.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a hall call device for calling a plurality of elevators in service between multi-floor floors, an elevator provided at a multi-story landing, and a hall calling device for each hall call that occurs. and a device for allocating a selected elevator to a selected elevator, the elevator control device for servicing the elevator assigned to the generated hall call. A configuration in which a hall is equipped with a device that can select an elevator in a minimum load state based on the load state determination means, and a device that, when the selection device is operated, assigns the elevator in the minimum load state among the elevators to the hall call. It is said that

[Effect]

Since the present invention has the above configuration, when you want to call an elevator with a small number of tower passengers, if you operate the selection device and then operate the hall call device within a predetermined time, you can call the elevator with the least number of tower passengers. Since the elevator responds to the hall call, the operation efficiency of the elevator is not affected.
Moreover, it is possible to eliminate the troublesomeness of the hailing operation, and to meet the expectations of waiting passengers who wish to ride in an elevator with a small number of passengers.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a block circuit diagram of an elevator group management system capable of calling light-load elevators.

The empty call detection circuit 1 detects whether the empty call button of each floor hall is pressed. Similarly, the hall call detection circuit 2 detects whether the hall call button of each floor hall is pressed. The output signals 1a and 2a of these detection circuits are used to register calls for each floor, and when each car stops at designated W3 and finishes its service, a reset signal 8 A c is sent.
The call registration circuit 3 cancels the registration by ~8Nc.
It is.

The call registration circuit 3 registers the empty call when there is an empty call after the hall call, transmits an empty call registration signal 3a to the car weight measuring circuit 4, and registers the hall call when there is only a hall call. The hall call signal 3b is transmitted to the hall call allocation circuit 7.

When the empty call registration signal 3a is transmitted, the car weight measuring circuit 4 measures the weight of serviceable elevator cars to detect the lightest car. Status signals 8Ab to 8Nb from each car are detected, and the status signals 8A,
b~8Nb and output signal 4a from car weight measurement circuit 4
The empty call allocation circuit 5 determines the car to be serviced on the empty call registration floor based on the above. Similarly, the status signals 8Ab to 8Nb from each car are detected, and the status signals 8Ab to 8Nb are detected from each car.
The hall call allocation circuit 7 determines the car to be serviced on the hall call registration floor based on Ab to 8Nb and the hall call registration signal 3b from the call registration circuit 3. The output signal from the circuit 7 is received by the vacant call assignment circuit 5 and the hall call assignment circuit.

It is the assignment management circuit 6 that actually sends a signal informing the service floors to the control circuits 8A to 8N of each car. Elevator control circuits 8A to 8N control the operation of each elevator and transmit the current state of the elevator to each circuit. 9
A to 9N are elevators serving each floor.

Next, the present embodiment will be explained in detail using the flowchart shown in FIG.

Suppose that the up button is pressed in the elevator hall on the 5th floor. At this time, the hall call detection circuit 2 notifies the call registration circuit 3 of the detection of the 5th floor up call using the hall call detection signal 2a. When the call registration circuit 3 receives this hall call detection signal 2a, it waits for an empty call detection signal, and if it is not detected within a certain period of time, it determines that it is a normal hall call and registers the hall call. Do this. In this way, when an empty call is not detected, the hall call registration signal 3b is transmitted to the hall call allocation circuit 7, and the hall call allocation circuit uses the conventional group management control method to select the car that will arrive at the 5th floor early and assign it to the hall call registration signal 3b. It sends an assignment signal to the car's control circuit and sends it to the 5th floor for service.

If the empty call button on the same floor is pressed within a certain period of time after the previous 5th floor hall call detection signal is detected, and the empty call detection signal 1a is transmitted from the empty call detection circuit 1 to the call registration circuit 3, the The registration circuit 3 determines that the call is an idle call and performs idle call registration. Then, a call registration signal 3a is sent from the call registration circuit 3.
The signal is transmitted to the car weight measuring circuit 4. The car weight measurement circuit 4 to which the empty call registration signal 3a has been transmitted must meet the following conditions: first, the car weight measuring circuit 4 must be able to use a serviceable elevator (as it is an up call on the 5th floor, the car is located below the 5th floor and is in up operation; If it is not suitable, another elevator is checked, and if it is suitable, the weight in the elevator car is checked as a second condition. Then, the first and second conditions are checked for each elevator one after another to detect which elevator is the lightest. If the lightest car is found, this car is temporarily assigned to the empty call registration on the 5th floor. Next, it is checked whether the weight in the temporarily allocated car is less than half of the maximum loading capacity of the elevator, and the result is transmitted to the empty call allocation circuit. If the result is more than half, the tentatively allocated basket will be
An elevator that is not assigned to a floor and then switches to up operation on floors below the fifth floor is made to serve the fifth floor. On the other hand, if the result is less than half, next, a car call is performed to check whether there is a car registered for the 5th floor among the elevators that were previously found to be able to service the 5th floor.

If so, calculate which car will arrive at the 5th floor first based on the tentatively allocated cars. If there is a possibility that the car may arrive at the 5th floor earlier than the provisionally assigned car, that car will be served on the 5th floor, and the provisionally allocated car will not be served on the 5th floor. On the other hand, if the tentatively assigned car can arrive first, or if there is no call registration for the 5th floor, the tentatively assigned car should be moved to the 5th floor.
Service on the floor.

As described above, by pressing the empty call button, it is possible, although not always, to board an empty elevator.

〔Effect of the invention〕

Since the present invention has the above configuration, when you want to call the elevator with the least number of passengers, if you operate the 1 selection device and then operate the hall call device within a predetermined time, the elevator with the least number of passengers can be called. Since it responds to the hall call, it does not impede elevator operation efficiency.
Moreover, it is possible to eliminate the troublesomeness of the call operation, and to meet the expectations of waiting passengers who wish to ride in an elevator with a small number of passengers.
