Elevator controller

Abstract

The present invention provides an elevator control device, which has: a hall door with a smoke-blocking function, a door control device and a device for notifying passengers of necessary information are arranged on the car, and a fire notification unit is arranged on the side of the elevator control panel , in the case of receiving a detection signal such as a fire, the above-mentioned notification device notifies a fire related message; the fire control operation control part, in the case of receiving a detection signal of a fire, etc., makes the car directly run through the fire control operation to the evacuation floor; the door opening time measurement part measures the door opening time when the above-mentioned car arrives at the evacuation floor and opens the door; Therefore, when a detection signal such as a fire is received, the car door and the hall door are closed at the same time to prevent smoke from moving to other floors through the lifting passage.

Description

technical field [0001] The present invention relates to an elevator control device that performs control in the event of a fire or the like to utilize the smoke blocking function of an elevator hall door. Background technique [0002] In the past, a fire-proof and smoke-proof rolling door mechanism was installed in front of the elevator lobby. The structure of the fire-proof and smoke-proof rolling door mechanism is that when a detection signal such as fire is received from a fire and smoke detector installed in a building, the rolling door Descending from the top side of the elevator hall, the side of the elevator hall is separated from the elevator passage, so that the smoke will not move to other floors through the elevator passage. [0003] Also, in recent years, the following countermeasures have been taken to prevent the movement of smoke generated when a fire breaks out: Installing an elevator hall door with a smoke blocking function, the elevator hall door is provide...

AI Technical Summary

Problems solved by technology

[0006] Therefore, in the above-mentioned elevator system, countermeasures are taken to prevent the smoke generated when a fire occurs from passing through the elevator passage and moving to other floors. When the car runs directly to the evacuation floor or is in the open state after reaching the evacuation floor when a fire occurs, or the car opens and closes the door slowly, even if there is a waiting ladder with a smoke-blocking seal and a smoke-blocking function The hall door cannot function as a smoke barrier

[0007] In addition, when driving equipment installed in the car, such as an air-conditioning fan, it has the effect of promoting the movement of smoke, and also has the problem of not being able to perform the smoke blocking function.
