Abstract

The invention provides a method and a system for detecting person trapping in an elevator. According to the logic combination between multiple outputted detection signals of the elevator from an elevator controller, the person trapping state of the elevator is detected. The detection signals comprise a person carrying signal, a door lock signal, a fault signal and an overhauling signal; when the person trapping state is determined, a corresponding alarming signal can be sent out. The method and the system have the advantage that the problem of false judging on person trapping in the elevator can be effectively solved.

Description

Technical field [0001] The invention relates to detection technology, in particular to a detection method and system for elevator trapped people. Background technique [0002] An emergency call button is usually provided on the key panel in the elevator, which is used to allow the personnel carried by the elevator to call the external monitoring personnel for help when the elevator is abnormal. This is also a common method to solve the problem of people trapped in elevators. [0003] However, many people do not know or dare to press the emergency call button; or when people are in a state of tension and panic, they forget to press the emergency call button; or, when the emergency call button fails, they cannot notify the external monitoring in time personnel. [0004] In order to solve the above problems, the existing method is to add sensors (such as infrared sensors, etc.) for detecting whether there are people in the elevator in the elevator car. Although the addition of this t...
