[Abstract]:It is difficult for the existing coal mine safety system to know exactly the number, location and life state of the trapped miners. A set of auxiliary rescue system is urgently needed, which can quickly determine the exact location of the underground workers after the accident. Grasp the vital signs of trapped persons and provide reliable basis for rescue. In this paper, the attitude recognition and vital sign monitoring system of mine personnel based on wireless sensor network is developed, which can overcome the influence of complex environment on underground information transmission and make the transmission data stable and reliable. In the event of an accident, information such as the location of personnel, the number of persons trapped and the specific location can be immediately inquired from the monitoring computer to provide scientific basis for rescue work and reduce the loss of personnel to the minimum. This system is usually composed of ground central station equipment, data communication equipment, monitoring equipment, wearable sensor system to realize the continuous monitoring of underground environment multi-parameter. It can accurately distinguish the wearing person running, walking, standing immobility and basic physiological state indicators. This system uses the wireless sensor network system based on ZigBee protocol to collect the basic physiological indexes of underground personnel through intelligent nodes and to recognize their behavior posture. In order to realize the monitoring of vital sign information of underground personnel, it overcomes the shortcomings of small number of sensor nodes, difficult to move, poor network expansibility, difficult location and so on. Based on the present situation of mine monitoring system in China, an intelligent and extensible monitoring system is established, which can not only monitor the underground environmental information, but also monitor the vital signs and behavior of personnel. Real time monitoring and early warning analysis of mine environment and personnel through wireless sensor network is an important problem urgently needed to be solved in modern mines. In this paper, the intelligent personal wearable safety system is developed by using the technology of Internet of things, intelligent sensing and pattern recognition technology. The system is composed of three parts: intelligent information collection node, Redundant communication unit and ground monitoring and diagnosis system. The specific research contents are as follows:. 1 vital sign monitoring. 2 recognition of human behavior attitude based on accelerometer. 3. Collection and analysis of environmental parameters. Wearable system design. 5. Build downhole communication link with dual redundancy based on Mesh.
