Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] This invention relates to an improvement in an operating device for a group control elevator.

[Background of the invention]

The group control elevator is as described in Japanese Patent Application Laid-Open No. 49-949, and this device selects the most suitable elevator to respond to a hall call in order to improve the service for elevator passengers. It is something. However, some passengers, if 70% of passengers are boarding the elevator that answered the hall call, do not board the elevator and register the first hall call again.
There are cases where an elevator with fewer passengers is called and boarded, and each time a hall call is registered, the elevator that can respond to that call is stopped by the call for that floor. There was a problem in that the operating efficiency of the elevator was extremely reduced.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a group control elevator operating system that prevents passengers from making unnecessary calls to the hall.

[Summary of the invention]

A feature of the present invention is that a passing operation command is issued to cause an elevator car to operate in response to a hall call based on the closed or normal operation pattern of the group control elevator or the output of a specific time period detection signal from a time period detection device. Normally, the car loading detection value for issuing a passing operation command is set close to the specified value for car loading, but this configuration is configured so that the passing operation command is issued when this loading detection value is smaller than the normal setting value. Accordingly, the elevator users are not refused boarding based on the tower multiplier of the called car, and the reduction in the operating efficiency of the elevator due to wasteful hall call registration can be prevented.

[Embodiments of the invention]

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

In the figure, A is a load detection device that closes the contact with a load of 80 force corresponding to the car load, B is a load detection device that closes the contact with a 60 force load of the car load, C is a time period detection device that closes the contact at an arbitrary time, D is a signal that closes the contact as a closed pattern when the elevator traffic demand falls below a preset demand, and E is a signal that closes the contact as a normal pattern when the traffic demand is greater than the closed pattern. , 1 and 3 are OR
Gate 2 is an AND gate, and 4 is a full pass command relay that is energized when the output of OR gate 3 is issued.

Next, the operation of this embodiment will be explained.

For example, in traffic demand where passengers are concentrated in elevators such as during dispatch time or lunch time, the time period detection device contact C1 closed pattern contact and normal pattern contact E are open and OR gate 1 does not output an output. 6 of the basket loading capacity
Even if load detection device B, which detects zero-force load, closes the contact, A
ND gate 2 produces no output. Therefore, OR
The condition for issuing an output from the gate 3, energizing the full penetration command relay 4, and instructing the elevator to pass the full penetration is limited to the case where the load detection device contact A, which detects the 80-force load of the load, is closed. In the closed pattern where there is less concentration of passengers in the elevator -, the closed pattern contact is closed OR
An output is issued to game 1-1.

Therefore, when load detection device B, which detects the 60-force load of car load 1, closes its contacts, AND gate 2 outputs an output, and the contact of load detection device A, which detects the 80-force load of car load 1, closes. Immediately, the OR gate 3 outputs an output, and the full pass command relay '1 is energized, instructing the elevator to complete the pass. Also, when the time period detection device contact C1 or the normal pattern contact E is closed, the operation is the same as when the open number pattern contact is closed, so a description thereof will be omitted.

According to this embodiment, the set value of the car loading load that issues the 11 force penetration command is reduced in accordance with the concentration of passengers in the elevator, and the number of passengers boarding the elevator is determined by the tower multiplier of the car. It has the effect of preventing rejection.

In this embodiment, the load detection devices A and B are mechanical contacts, but they may also be constructed using differential lances, and the output of the differential transformer can be selected for any load using a ratio calibrator. .

Furthermore, the input to the OR gate 1 is not limited to the conditions of the embodiment, and any suitable conditions may be selected depending on the service status of the group elevator.

〔Effect of the invention〕

As explained above, according to the present invention, the set value of the car loading load that generates the full pass command is reduced in anticipation of the condition in which elevator passengers are refused boarding due to the number of passengers boarding the car. There is no need to refuse entry, and it is possible to prevent a decline in elevator operating efficiency due to wasteful registration of hall calls.

[Brief explanation of drawings] The figure shows a logic circuit showing an embodiment according to the present invention.
