Elevator security rescue system and rescue method based on same

Abstract

The invention provides an elevator security rescue system and a rescue method based on the same, wherein the elevator security rescue system comprises a rescue action signal input unit, an elevator detecting unit and a security rescue main control panel, wherein the rescue action signal input unit is used for inputting an rescue action executive command; and the elevator detecting unit is used forobtaining a light curtain signal, a car door opening-closing situation signal, a landing door opening-closing situation signal, an elevator failure situation signal, an elevator overhaul situation signal, an elevator safety circuit situation signal and an elevator car position signal. With adoption of the elevator security rescue system and the rescue method based on the same, the problem in theprior art that the car suddenly ascends or descends caused by weight variation of the car when a trapped passenger goes in and out of the car is solved, the problem in the prior art about the shearingrisk caused by operation of the car when the landing door and the car door is opened is solved, and the problem in the prior art that the car door and the landing door are not aligned caused by factitious erroneous judgement of the car position is solved.

Description

technical field [0001] The invention relates to a processing method and processing equipment for elevator personnel trapped, in particular to an elevator safety rescue system and a rescue method based thereon. Background technique [0002] In the prior art, the elevator includes: a monitoring system, a guide rail, a car, a lifting mechanism, landing doors and elevator doors. The guide rail is used to guide the movement of the car, and the lifting mechanism is connected to the car. There are elevator doors for opening and closing the car. The elevator shaft is equipped with an elevator door corresponding to each floor. A landing door for opening and closing the elevator door is installed on the elevator shaft. The monitoring system is used to monitor the opening and closing of the landing door and the elevator door. Although the rescue can be achieved, the following problems exist: [0003] 1. During the rescue process, since it is impossible to intuitively judge (effectivel...

AI Technical Summary

Problems solved by technology

[0006] The present invention provides an elevator safety rescue system and a safety rescue method based on it, which solves the problem in the prior art that the car suddenly rises or lowers due to the weight change of the car when the trapped person enters or exits the car, and solves the problem in the existing In the technology, there is a problem of shear risk caused by the car running when the landing door and the elevator door are opened, and it solves the misalignment between the elevator door and the first floor door in the prior art due to the easy misjudgment of the car position The problem
