【摘要】：现阶段，我国煤炭安全生产形势严峻，制约煤炭工业发展的突出问题之一就是煤矿的安全问题，缓解煤炭安全生产的重要方法是加强对煤矿生产的安全监控，对煤矿安全的科研工作也要进一步的研究，基于上述问题，本文将数据融合技术融入煤矿安全监控系统中，实现对煤矿安全监控系统的改进。井下瓦斯浓度、一氧化碳浓度、温度、风量等因素是影响煤矿安全生产的主要因素，本文采用多传感器数据融合的方法，将现场检测的多个传感器数据信息进行融合，采用局部融合和全局融合两级融合方法对煤矿多传感器数据进行融合，局部融合是一级融合，即对多个同类传感器信息进行融合；全局融合即二级融合，采用D-S证据推理对不同类传感器数据进行融合。通过数据融合得到最终煤矿的灾害类型，根据灾害类型，工作人员采取相应的措施避免灾害的发生。本文设计了系统的硬件部分，系统硬件主要是智能分站。采用ARM微处理器和51微处理器构成双核处理器，电路包括系统电源电路、对井下各参数的采集电路、CAN通信电路等。将采集到的井下参数经过数据融合得到灾害类型，当井下有参数超标时，井下分站立即将危险信息通过CAN总线传到上位机，上位机对危险信息迅速处理并指导井下进行相应的动作，避免危险的发生。系统软件设计部分包括控制器软件和上位机监控软件。控制器软件主要设计了各个模块的工作流程；上位机软件采用VB6.0来设计，操作人员通过上位机监控软件设定系统参数，，查看瓦斯浓度、温度等参数以及融合结果，通过报警信息对井下设备进行控制。
[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.
