Life safety monitoring and early warning system and method

Abstract

The invention provides a life safety monitoring and early warning system and method, and belongs to the technical field of intelligent control. The system comprises an intrinsic safety type watch, a multi-parameter measuring device, a power air supply respirator, an intrinsic safety substation and a server. Signal transmission at any position in a monitoring space is realized by constructing a Bluetooth mesh ad hoc network, and acquisition information of any worker is ensured to be monitored. The system not only can monitor vital signs, breathing parameters and other parameters representing the physical condition of a worker in real time, but also can monitor the gas concentration information of the surrounding environment in real time, realizes a bidirectional safety early warning function based on the environment and the worker, realizes mesh network extension through a mode of inputting nodes, and therefore, realizes underground network recovery on a mine.

Description

technical field [0001] The invention relates to the technical field of intelligent control, in particular to a life safety monitoring and early warning system and method. Background technique [0002] The environment of coal mine operation is harsh, with heavy dust and poor ventilation conditions. There will be harmful gases such as methane, carbon monoxide and hydrogen sulfide underground. When the concentration of methane exceeds the limit, it will cause a coal mine explosion. When the concentration of carbon monoxide and hydrogen When the temperature is too low, it will make it difficult for underground operators to breathe, which will seriously affect the health of operators. At present, the monitoring of the vital sign parameters of the operators is still limited to the measurement with a sphygmomanometer before going down the mine, and the real-time monitoring of the vital sign parameters of the operators cannot be realized. For miners with relatively weak vital signs,...

[0002] The environment of coal mine operation is harsh, with heavy dust and poor ventilation conditions. There will be harmful gases such as methane, carbon monoxide and hydrogen sulfide underground. When the concentration of methane exceeds the limit, it will cause a coal mine explosion. When the concentration of carbon monoxide and hydrogen When it is too low, it will make it difficult for underground operators to breathe, which will seriously affect the health of operators

At present, the monitoring of the vital sign parameters of the operators is still limited to the measurement with a sphygmomanometer before going down the mine, and the real-time monitoring of the vital sign parameters of the operators cannot be realized. For miners with relatively weak vital signs, when an emergency When a disease occurs, it will be very dangerous. If the underground network signal is poor, the distress signal cannot be uploaded to the well for timely treatment. This is extremely irresponsible for the lives of workers.

[0003] Moreover, most of the existing networks are single-hop networks. If a single transmission node is damaged, the communication will be interrupted, the power line will be interrupted, the alarm signal will not be transmitted to the well, and the fault diagnosis will not be timely, which will delay production. Existing equipment monitoring can only be uploaded to the well. Centralized monitoring leads to a long decision-making cycle, which prolongs the effective time of equipment maintenance. At present, there is no equipment that can integrate the environmental information of the mine and the vital sign information of the miners to realize the two-way safety warning function of the environment and personnel.
