【摘要】：随着煤矿井下安全监测技术的快速发展,我国煤矿安全生产形势大有改善。但是,目前我国煤矿井下安全监测仍普遍存在诸多不足,如矿工难以及时了解自身周围的环境信息、监测传感器的布置难以跟上采掘工作面的推进、缺乏有效的煤矿事故预警手段等。因此,建立跟随矿工的井下安全监测移动终端,将对目前我国煤矿井下安全监测大有裨益。本文分析了煤矿井下安全监测国内外研究动态,针对目前我国煤矿井下安全监测存在的一些问题,深入研究了嵌入式技术、传感器技术、无线通信技术、数据分析与处理技术等,引入了低功耗、移动性强、小型化的监测思想,设计了煤矿井下安全监测智能头盔系统。本系统由数据采集层、数据传输层和智能监测分析层三部分组成。在数据采集层中以矿工安全头盔为载体,集成以S3C2440控制器为核心的各功能模块,完成井下人员定位、矿工作业环境信息监测、实时语音通信、远程视频监测、声光报警等功能;在数据传输层中通过无线传输转有线传输的方式,完成数据采集层和智能监测分析层之间的数据传输;在智能监测分析层中通过本系统开发的监测软件,完成对监测数据的显示、存储、报警、管理等功能,并通过DDE通信技术调用MATLAB软件,基于层次分析法和模糊综合评判理论,对监测数据进行分析,完成瓦斯预警。最后对系统运行测试,经验证,测试结果与理论分析一致。煤矿井下安全监测智能头盔的研究,是对我国煤矿井下安全监测的重要补充。经测试表明,本系统较好地实现了各项预期目标,对它的推广与应用将对煤矿安全生产和保障矿工生命安全具有重要的工程价值。
[Abstract]:With the rapid development of underground safety monitoring technology, the situation of coal mine safety in China has been greatly improved. However, at present, there are still many shortcomings in mine safety monitoring in our country. For example, it is difficult for miners to know the environmental information around them in time, and the arrangement of monitoring sensors is difficult to keep up with the advance of mining face. Lack of effective coal mine accident warning means and so on. Therefore, the establishment of underground safety monitoring mobile terminal following miners will be of great benefit to mine safety monitoring in our country at present. In this paper, the domestic and foreign research trends of underground safety monitoring are analyzed, and the embedded technology, sensor technology, wireless communication technology are deeply studied in view of some problems existing in mine underground safety monitoring in our country. With the introduction of low power consumption, strong mobility and miniaturization, the intelligent helmet system for mine safety monitoring is designed. The system consists of data acquisition layer, data transmission layer and intelligent monitoring and analysis layer. In the data acquisition layer, the miner safety helmet is used as the carrier and the S3C2440 controller is the core of each functional module to complete the functions of underground personnel positioning, miner working environment information monitoring, real-time voice communication, remote video monitoring, acousto-optic alarm and so on. In the data transmission layer, the data transmission between the data acquisition layer and the intelligent monitoring and analysis layer is completed by wireless transmission to wired transmission, and the monitoring software is developed in the intelligent monitoring and analysis layer through this system. The functions of displaying, storing, alarming and managing the monitoring data are completed, and the MATLAB software is called through DDE communication technology. Based on the analytic hierarchy process (AHP) and fuzzy comprehensive evaluation theory, the monitoring data are analyzed and the gas warning is completed. Finally, the system running test, after verification, the test results are consistent with the theoretical analysis. The research of intelligent helmet for underground safety monitoring in coal mine is an important supplement to mine safety monitoring in China. The test results show that the system has achieved all the expected goals, and its popularization and application will be of great engineering value to the safety of coal mine production and the safety of miners' lives.
