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.

Embodiment Construction
[0080] The embodiments of the present application disclose a method for personal protection in dangerous working conditions.
[0081] refer to figure 1 , a method of personal protection in hazardous conditions comprising:
[0082] S100. Acquire first inclination information transmitted by a preset first inclination sensor inside the building and first displacement information transmitted by a preset first laser displacement sensor outside the building.
[0083] In a specific implementation, the inclination angle of the building is usually represented by the inclination angle of the load-bearing wall of the building. The first inclination sensor is a dual-axis inclination sensor, which is preset on the wall of the building, and is closely attached to the wall of the building. Using Newton's second law, the first inclination information of the building is measured, and the first inclination information is: The angle of inclination of the load-bearing walls of a building. Duri...

The present application relates to a method, device and system for personal protection in dangerous working conditions. The method includes obtaining the first inclination information transmitted by the first inclination sensor and the first displacement information transmitted by the first laser displacement sensor; comparing the first inclination information with the predicted Set the initial inclination information to obtain the first inclination change value; compare the first displacement information with the preset initial displacement information to obtain the first displacement change value; determine whether the first inclination change value exceeds the preset inclination threshold and the first displacement Whether the change value exceeds the preset displacement threshold; if the first inclination change value exceeds the inclination threshold and / or the first displacement change value exceeds the displacement threshold, a first-level alarm signal is sent to the cluster intercom, so that the cluster intercom outputs a first-level alarm signal. By monitoring the displacement and inclination of the building, it helps to reduce the probability of inaccurate monitoring by any sensor, and at the same time, it is convenient for rescuers to evacuate dangerous buildings in time according to the alarm signal output by the cluster walkie-talkie to ensure their own safety.
Description
technical field [0001] The present 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 my country, such as earthquakes, typhoons or fires. Building collapse accidents are very easy 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 at the rescue site. When...
