An elevator failsafe escape system

Abstract

The invention discloses a safe escape system during an elevator fault. The safe escape system comprises an elevator car, multiple sensors, an elevator controller, a fault detection module connected to a communication line arranged between the elevator car and the elevator controller, a fault safety control module provided with a fault detection data interface, a mode switching control interface, a communication network interface and a life information data interface, an operation mode switching module communicated with the mode switching control interface, a fault information sending module communicated with the communication network interface, a life information detection module communicated with the life information data interface and an interphone module connected with the fault safety control module. According to the safe escape system during the elevator fault, when an elevator is failed, trapped person can safely get out of the elevator in time, and the accident that passengers are trapped in the elevator car is prevented from occurring.

Description

technical field [0001] The invention relates to the technical field of elevator safety design, in particular to an elevator failsafe escape system. Background technique [0002] In the prior art, when an elevator operation failure occurs, since there may be passengers in the car, in order to prevent the passengers in the elevator from being restless and misoperating the car control panel to cause safety accidents, the control system of the elevator is designed in order to To ensure the safety of passengers, after the elevator fails, the operation of the car control panel will be automatically ignored to avoid safety accidents caused by passengers panicking and misoperation of the car control panel. At the same time, only the call button function is reserved to facilitate passengers trapped in the car When you can ask for help from relevant personnel, the elevator control system will lock the car to prevent slippage, and at the same time, you can only passively wait for exter...

AI Technical Summary

Problems solved by technology

[0003] However, the elevator control system includes different subsystems with multiple sensors and operating components. After a failure occurs, the maintenance personnel can only check or test each component of each subsystem one by one to find out the cause of the failure, and cannot quickly and accurately find out the location of the failure. , the maintenance efficiency of the elevator is not high, and the time for passengers trapped in the elevator is also prolonged, which increases the probability of passengers being in danger
