[Abstract]:At the present stage, the situation of coal safety production in our country is severe. One of the outstanding problems restricting the development of coal industry is the safety problem of coal mine. The important method to alleviate the safety production of coal mine is to strengthen the safety monitoring of coal mine production. On the basis of the above problems, this paper integrates the data fusion technology into the coal mine safety monitoring system, and realizes the improvement of the coal mine safety monitoring system. Underground gas concentration, carbon monoxide concentration, temperature, air volume and other factors are the main factors that affect the safety of coal mine production. In this paper, the multi-sensor data fusion method is used to fuse the data information of multiple sensors detected in the field. The method of local fusion and global fusion is used to fuse the multi-sensor data of coal mine. The local fusion is the first level fusion, that is, the fusion of the information of the same kind of sensors, the global fusion is the second level fusion. D-S evidential reasoning is used to fuse different kinds of sensor data. Finally, the disaster type of coal mine is obtained by data fusion. According to the disaster type, the staff take appropriate measures to avoid the disaster. In this paper, the hardware of the system is designed. The hardware of the system is mainly intelligent sub-station. The dual-core processor is composed of ARM microprocessor and 51 microprocessor, and the circuit includes the power circuit of the system. After data fusion, the disaster type is obtained. When the parameters in the mine exceed the standard, the danger information is immediately transmitted to the upper computer by the CAN bus. The upper computer processes the dangerous information quickly and instructs the corresponding action to avoid the danger. The software design of the system includes the controller software and the host computer monitoring software. The controller software mainly designs the work flow of each module. The upper computer software is designed with VB6.0, and the operator sets the system parameters through the upper computer monitoring software. Check gas concentration, temperature and fusion results, through alarm information to control the underground equipment.
