Detection system with function of protecting accidental movement of elevator cars and method thereof

Abstract

The invention discloses a detection system with a function of protecting accidental movement of elevator cars and a method thereof. The detection system comprises a control system, a speed and displacement measuring subsystem, a safety circuit monitoring subsystem, a brake controlling subsystem and a handheld terminal, wherein the speed and displacement measuring subsystem is connected with the control system; the safety circuit monitoring subsystem is respectively connected with the control system and an elevator car accidental movement protection device and is used for monitoring actions ofa safety circuit in the protection device; the brake controlling subsystem is respectively connected with the control system and an elevator brake circuit and is used for controlling opening and closing of an elevator brake. According to the detection system, the control system is used for respectively controlling a plurality of subsystems to detect and protect the accidental movement of the elevator cars; the detection system has universality, reasonability and safety, can be used in processes of mounting and self-inspecting, supervision and inspection, periodic inspection, repair and maintenance, and supervision and random checking of the elevators, and has high practical value.

Description

technical field [0001] The invention belongs to the field of inspection and detection of special equipment, and in particular relates to a detection system and method for the protection function of accidental movement of an elevator car. Background technique [0002] With the rapid development of the economy and the ever-changing cities, various high-rise buildings are increasing day by day. Elevators installed in high-rise buildings are playing an increasingly important role in people's lives and have become an important means of transportation for people's daily travel. At the same time, as a kind of electromechanical special equipment, the safety of elevators has attracted more and more attention. Among them, the accidental movement of the elevator car is very dangerous to passengers, and once it happens, the consequences will be extremely serious. [0003] Unexpected movement of the elevator car is an extremely dangerous state, which is the main cause of accidents such ...

AI Technical Summary

Problems solved by technology

To sum up, there is currently no general, reasonable and safe detection method for the protection function of the accidental movement of the elevator car, so as to facilitate the use in the inspections of elevator installation self-inspection, supervisory inspection, regular inspection, supervision and spot check, etc.
