JPH06271257A - Control device for elevator - Google Patents

Abstract

PURPOSE:To prevent a canning accident from happening by forcibly opening a door, in the case of confinement in a car of an elevator. CONSTITUTION:In the case of dispatching no operation signal regardless of providing a passenger from inside a car by a passenger detector (load detector 3 and IR detector 4), this case is input to a microcomputer part of an elevator control plate 5, so as to force an elevator gate door opened when elapsed a specific time. By operation thus performed, a little child and a physically handicapped person incapable of pressing a button, even when left in the cage, are prevented from being confined.

Description

Detailed Description of the Invention

[0001]

The present invention relates to elevator control systems.

[0002]

2. Description of the Related Art In normal elevator automatic driving, when a passenger gets into an elevator car and closes the door, either the door open button in the car is pushed, the destination floor button is pushed, or the hall button is pushed at the landing. If not, the door will not open and the car will not run. For this reason, the person on board will be trapped as it is.

[0003]

This is a situation that occurs when an infant or a physically handicapped person who cannot reach the buttons in the car gets into the car by himself. The car does not run, the door does not open, the occupant is trapped inside the car, and remains there until the next elevator operation by another person or until the outside person notices.

In such a case, it is an object of the present invention to provide a control device capable of safely operating a car so that passengers can safely get off without trapping passengers.

[0005]

[Means for Solving the Problems] A detection device for detecting the presence / absence of passengers in a car, and a no-signal detection means for detecting that an operation signal is not transmitted from the inside of a car with passengers,
The timer is activated, and after a certain period of time, the door at the entrance and exit is forcibly opened and a no-passenger is detected, or the door remains open until an operation signal is sent from inside the car. Provide a means to open the door.

[0006]

With this configuration, when a passenger who cannot press the operation button for any reason is trapped inside the car,
Forcibly open the door of the entrance and exit to prevent a canning accident.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described based on the embodiments shown in FIGS.

A load cell 3 is provided on a car floor 2 of an elevator car 1 to detect a load applied to the floor (tentatively set to 10 kg or more). Further, an infrared detector 4 is provided in the car to detect passengers based on the presence or absence of infrared rays based on the body temperature in the car.

With this construction, the load detector 3 can detect not only a person but also an abandoned baggage, and a light weight organism (infant, small animal, etc.) is detected by the infrared detector 4. In this way, detection of passengers trapped by these two different detectors is ensured.

Further, the elevator control panel 5 is provided with a rescue operation means when such passengers are trapped.

When an elevator equipped with such a detector and rescue operation means is in automatic operation, when the car lands on the floor and the door opens and closes and remains as it is, the operation is controlled as follows.

When the car is on the floor, the door is opened and closed, and the car is still there and a passenger is detected, the rescue operation means for the passenger operates as shown in the flowchart of FIG.

That is, when the passenger is detected after the door is closed, this is input to the microcomputer unit 6 of the elevator control panel 5, the timer of the microcomputer unit 6 is activated, and if the operation signal in the car is not input even after a predetermined time has elapsed, The door opening instruction signal is output from the microcomputer unit 6 to open the door.

After the door is opened, the door remains open until an in-car operation signal is input or the passenger detectors 3 and 4 are turned off. If passengers do not leave the car after a certain period of time,
An alarm is sent to the car monitoring panel (management room management panel), the manager inspects the car, takes necessary measures, and returns to normal operation.

Industrial Applicability According to the present invention, a passenger with a physical disability or an infant can be prevented from being jammed and a safer elevator can be provided.
