Dangerous working condition individual protection method, device and system

Abstract

The invention relates to a dangerous working condition individual protection method, device and system. The method comprises the steps of: acquiring first inclination angle information transmitted by a first inclination angle sensor and first displacement information transmitted by a first laser displacement sensor; comparing the first inclination angle information with preset initial inclination angle information to obtain a first inclination angle change value; comparing the first displacement information with preset initial displacement information to obtain a first displacement change value; judging whether the first inclination angle change value exceeds a preset inclination angle threshold value or not and whether the first displacement change value exceeds a preset displacement threshold value or not; and if the first inclination angle change value exceeds the inclination angle threshold value and / or the first displacement change value exceeds the displacement threshold value, sending a primary alarm signal to cluster interphones, so that the cluster interphones output primary alarm signals. By monitoring the displacement and an inclination angle of a building, the probability of inaccurate monitoring of any sensor can be reduced, meanwhile, rescue workers can timely evacuate the dangerous building according to the alarm signals output by the cluster interphones, and the safety of the rescue workers is guaranteed.

Description

technical field [0001] The invention relates to the field of personal protection, in particular to a method, device and system for personal protection in dangerous working conditions. Background technique [0002] In recent years, various disasters have occurred frequently in our country, such as earthquakes, typhoons or fires. Building collapse accidents are very likely to occur. Building collapse will cause a certain number of people to be buried. At this time, it is extremely important to carry out systematic rescue work. Under the influence of disaster accidents, buildings are prone to secondary collapse, which endangers the personal safety of rescuers who enter the building for search and rescue and the people trapped in the building. [0003] At present, there are a large number of newly recruited rescuers in the rescue team. Due to the lack of actual combat experience, it is difficult to accurately assess the danger level of the buildings on the rescue site. When the ...

Problems solved by technology

[0003] At present, there are a large number of newly recruited rescuers in the rescue team. Due to the lack of actual combat experience, it is difficult to accurately assess the danger level of the buildings on the rescue site. When the buildings collapse again, it is difficult to ensure their own personal safety.
