Communication system for self-help rescue of people trapped in elevator

Abstract

The invention relates to the field of machinery, in particular to a communication system for self-help rescue of people trapped in an elevator. A communication system for self-help rescue of people trapped in an elevator comprises a communication system body, the communication system body comprises a communication device arranged in an elevator car, the communication device comprises a shell installed on the side wall of the elevator car and an audible and visual alarm installed on the top wall of the elevator car, and a control panel connected with an elevator control cabinet is arranged in the shell. And the audible and visual alarm is electrically connected with the control panel. Through the design, the communication system for self-help rescue of people trapped in the elevator is provided, the use safety of the elevator is improved through cooperative work of the control panel, the audible and visual alarm, the voice prompter and other components connected with the elevator control cabinet, the design is convenient to prompt and help trapped people take corresponding measures, and the safety of the elevator is improved. And the safety of trapped persons in the elevator is improved.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a communication system for self-help rescue of trapped elevators. Background technique [0002] The elevator is a fixed lifting equipment serving the specified floors. However, due to various reasons, the elevator is faulty and shuts down people, which may easily cause passengers to be trapped in the elevator car. Only after the maintenance personnel go to the control cabinet to remove the fault first, and then open it with the triangular key The elevator door will be used to rescue the trapped people. If the rescue personnel cannot be contacted for a long time, there will be a greater risk. In an emergency, the fire brigade must use the rescue method to rescue the trapped people. When the existing elevator fails and traps people, the elevator control cabinet will control the elevator to stop running and generate a fault code until rescuers or maintenance personnel arrive and deal with the...

AI Technical Summary

Problems solved by technology

When the existing elevator fails and traps people, the elevator control cabinet will control the elevator to stop running and generate a fault code until rescuers or maintenance personnel arrive and deal with the elevator fault. During this process, the trapped people are under great psychological pressure. It is easy to cause panic; the failure of the elevator is not clear, and the trapped people cannot respond in time; the communication signal of the trapped people is poor, the rescuers cannot be notified in time, and the trapped people wait for a long time, etc., which reduces the safety of the elevator.
