JPS6052074B2 - Elevator door opening time control method - Google Patents

Description

[Detailed Description of the Invention] Conventionally, there are the following methods for controlling monthly time: 1) Fixed time period 2) Based on car load 3) Using approach detector, etc. However, 1 is inefficient, and 2 and 3 are It has the disadvantage of being complicated and expensive.

Generally, the time required to get on and off an elevator depends on whether you respond to a car call, a hall call, or both a car call and a hall call. If there are too many passengers, it is expected that boarding and alighting will take a long time due to congestion inside the car.

In addition, if there are many boarding calls and the monthly hours are long, operational efficiency will be hindered. The present invention was made in view of the above points, and
The purpose is to perform efficient monthly time control with a simple and inexpensive configuration by using a method of changing the monthly time limit depending on the number of calls.

An embodiment of the present invention will be described below with reference to the drawings.
The figure is a block diagram of one embodiment of the present invention.

In the figure, 1 is a well-known read-only memory circuit (hereinafter referred to as a ROM circuit), 2 is a latch circuit, 3 is a comparison circuit, 4 is a clock circuit, and 5 is a counter circuit. For simplicity,
The explanation will be given assuming that the number of stops is four, but the same applies when the number of floors increases. The address signal for the ROM circuit 1 is the driving direction signal UPNDOWN) floor signal 15-4.
5., UP hall call signals IFU-3, FUNDOWN hall call signals 2FD to 4FD, and car call signals 1C to 4C are connected.

In response to the monthly time setting command, the ROM circuit 1 outputs one word designated by the address signal as the door opening setting time to the latch circuit 2, and the latch circuit 2 holds the door opening setting time in response to the monthly time setting command. The counter circuit 5 counts the clock signal outputted by the lock circuit 4 during the moon opening based on the monthly signal energized during the moon opening. Comparison circuit 3 is a monthly open latch circuit according to the monthly signal; the contents of 2 and counter circuit 5
When the contents of the counter circuit 5 become larger than the contents of the latch circuit 2, a monthly command is generated.

The door opening time setting command is activated before the call for the service floor is canceled, and is deactivated after a certain period of time.

The time of de-energization may be the time of starting to close the door. In this case, the latch circuit 2 may be omitted. Driving direction signals UP, DOWN1 Floor signals 1S to 4S1 Hall call signals 1FU to 3FU. ．．
The door opening setting times corresponding to the combinations of D0WN hall call signals 'FD-4F'D1 and car call signals 1C to 4C may all be different, or the same value may be written.

This will be explained in more detail below using specific examples. First, regarding the case where the door opening setting time is changed depending on the number of car calls, for example, if the driving direction is ] and the second floor is serviced, the UP
=1, DOWN=0, saturation=1, 1S=? = O = 0, but in this case, the number of car calls is 4, the number of 2nd car calls is 3, the number of 3rd car calls is 2, the number of 4th car calls is 5 in case of 1, 1efi in case the number of 1 call is 0! It is possible that there is a problem.

If the contents of the ROM circuit 1 corresponding to these addresses are set to different values, the door opening setting time can be changed depending on the number of car calls. That is, when a large number of car calls occur, it is expected that car 1 will be crowded, so the door opening time is set longer, and when a small number of car calls occur, the door opening time is set shorter.

Similarly, in the case of hall calls, by setting the contents of the ROM circuit 1 to different values depending on the number of calls,
You can change the door opening setting time.

In other words, as the number of hall calls increases, the number of stops also increases, and the waiting time increases accordingly.The more hall calls occur, the shorter the door opening time is set within a range that does not cause any problems, thereby increasing operational efficiency. We aim to improve the quality of our products. Moreover, it is also possible to easily change the door opening setting time by combining the number of hall calls and the number of car calls.

As is clear from the above description, the elevator door opening time control method of the present invention allows efficient door opening time control with a simple and inexpensive configuration.

Claims (1)

[Claims] 1. Detecting at least one of the number of car calls or the number of hall calls in elevator door opening time control that services each floor in response to a call and automatically closes the door after a predetermined period of time has passed after the door is opened. The predetermined time period is changed to be longer when the number of car calls occurring is large and shortened when the number of car calls is small, and the predetermined time is shortened when the number of car calls occurring is large and is changed to be lengthened when the number of car calls is large. A method for controlling an elevator door opening time, characterized in that:
