Elevator protecting system with distributed air bags

Abstract

The invention provides an elevator protecting system with distributed air bags. The elevator protecting system comprises a car, a hoistway, floor safety modules, a server and a mobile phone APP. Eachfloor safety module comprises a ranging module, an air bag module, a floor communication module and a floor controller, wherein the ranging module is mounted horizontally and diagonally upwards to form an acute angle with the inner wall of the hoistway; the air bag module is below the ranging module by a distance of at least half height of the car; the floor controller is used for detecting statesof the air bag module, alarming under abnormal conditions, regularly reading measurement values of the ranging module, calculating time difference between car tail approaching and car head leaving toobtain car descending speed and alarming and controlling the air bag module to eject an air bag to slow down the car in descending under a stall condition. The elevator protecting system is high in reliability, each floor safety module is capable of independently judging the stall condition of the car and ejecting the air bags to protect passengers, and convenience in mobile phone APP remote monitoring is achieved.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator protection system with distributed airbags. Background technique [0002] The use of elevators in modern society is becoming more and more common. Almost everyone cannot do without elevators in their daily work, study and life. But elevator operation can break down unavoidably, even sometimes the accident that elevator car falls takes place, makes the passenger in the elevator caught off guard and accident occurs. This requires a self-protection measure for the falling elevator car when the elevator car falls and fails, so that the car encounters multiple resistances during the falling process, reduces the falling speed of the car, and maximizes the safety of the elevator car and the elevator car. A system of protection for persons riding in an elevator. Contents of the invention [0003] The purpose of the present invention is to provide an elevator protection ...

AI Technical Summary

Problems solved by technology

However, it is inevitable that elevators will malfunction, and sometimes accidents in which the elevator car falls will occur, which makes the passengers in the elevator caught off guard.
