Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an improvement in a door opening time setting device using an elevator car call.

[Technical background and problems of the invention]

Press the elevator hall call button to move the car to that floor (-
When a passenger gets on the car and makes a car call for the destination floor, the car arrives at the destination floor.

However, if many people are heading to the same destination floor, many people in the car will groan when a car call for the destination is made and they arrive at destination II#. There are times when the door closes completely while the door is being lowered.

(-1) With the conventional elevator car call door opening time setting device, when many people get on the car and go to the same destination floor,
When two people go to the destination floor, the time it takes to reach the destination floor is the same. therefore,
Because many people get off (the second is pressing the door open button or holding the monody/knee), it is always inconvenient and a problem for all women. be.

[Purpose of the invention]

SUMMARY OF THE INVENTION The present invention aims to provide an elevator door opening time setting mechanism for setting the door opening time from each multiplier in the car.

[Summary of the invention]

The present invention detects when many people are stuck in the elevator or when one person gets on the elevator, and then opens the elevator door for the corresponding time. .

[Embodiments of the invention]

The present invention will be described based on one embodiment shown in the drawings.

In Fig. 1, shi, - is the direct worker, 1 is the elevator car, 2 is the load detector, which converts the load in the car into its weight (2 pairs of windowed t air signals). 3 is an input buffer, 7 is an output buffer, which is a signal conversion device for interfacing with a central processing unit (hereinafter referred to as CPU), which will be described later, and 4 is a read/write memory device (hereinafter referred to as RAM). 5 is a read-only memory device (hereinafter referred to as ROM), in which programs necessary for the CPU to operate are written in advance.6 is a ROM in the CPU. The program (2) pre-written in 2 performs calculations and data processing. 8 is a relay that controls the opening and closing of elevator doors. It is energized when the door is opened by a command from the CPU, and is energized when the door is closed. 8a inputs to the CPU with its normally open contact that the door is open.

Next (2. Explain the operation of this embodiment. 3. The person using the elevator presses the hall call button, calls 1 for the elevator, and makes a car call for the destination floor. Door opening/closing control Relay 8 released, door 1]
A load detector 2 detects the magnitude of the load on the heel 1 when the heel is turned. This detected value is read from the υCPU 6 through the input buffer 3 according to a program according to the flowchart shown in FIG. 2, and is stored in the load cent address of the RAM 4.

The door opening time corresponding to the load is set to the door opening time set address I in RAM4.

When car 1 moves and arrives at the first floor, the CPU 6 executes a program as shown in the flowchart shown in Figure 3 (2). It is determined whether both a hall call and a car call have arrived.

If you are arriving at a hall call, get into car 1 (2) Set the required time to the door time set address in RAM 4, control the door opening/closing control relay 8 through the CPU 6 and output buffer 7, and open/close the door. do.

In the case of arrival by car call, the load at the floor where car 1 started is read through the load detector 2, input buffer 3, CPU 6, and stored in the RAM 4 by the program shown in the flowchart shown in FIG. Since the door opening time is stored in the H-type set address of
Set it to the door time set address of M4,
When car 1 stops, that value is temporarily set as the door opening time. Since not all people in the car get off at the floor where car 1 arrives first (2), the door opening time corresponding to the load of each person in the car (2 pairs of windows) is set in RAM.
4. Door time set address (=set in advance.

Figure 3 (2 shows σICre7C2) Every time a person descends from 1 (2 load changes υ, the change in load is constantly detected by load detector 2, input buffer 3, and CPU 6. When you get off the car, the value of the load address in RAM 4 decreases, so all the people in the car that you set in advance (from the door opening time that matches the two children, from 1 to vI!),
Subtract the door opening time from the reduced load (2 and υ), and use the difference as the door opening time at the stop floor (2). Use as a standard.

In addition, when the door closes (2, the program of the skill diagram shown in Fig.・When the door is opened due to the load inside the car, the next stop 1・r

, If you arrive at both the hall call and the car 1 child, the door time set value at the time of arrival at the call call mentioned above is added to the door time set value at the time of arrival from the hall call. is the door time set address in RAM 4 (set it again and use it as the door open time.

[Efficacy of invention]

As mentioned above: 2. In the present invention, the human child in the basket; when the side door is opened, 1 field is set in 1 layer. It allows you to get off the elevator safely and easily even when you are in a secluded place, which can be useful for improving the efficiency of elevator operation.

Claims (1)

[Claims] It has a load detector that detects the load caused by passengers in the elevator car, and a means for setting the elevator door opening time in response to the output of this load detector, and each time the elevator car stops at the destination floor. A door opening time setting device for an elevator, characterized in that the load detector detects the load inside the car and sets the door opening time in accordance with the load inside the car.
