针对现有的多参数气体测定器存在的量程小、不具有实效性等问题,通过研究多参数气体测定技术研发出矿山应急救援专用气体测定器,利用现有的井下无线Mesh网络和环网交换机,将现场实时环境数据传输到地面指挥中心;通过研究“爆炸三角形”的原理,对数据进行分析,在指挥中心主机上直接显示出O2、CH4、CO的浓度及温度值,并显示出“爆炸三角形”的图形及各气体成分所构成的坐标点,临近或达到警戒线时发出声光警报。系统能够实现对井下高浓度的环境信息进行实时监测,对避免次生灾害和提高救护的安全性具有重要意义。
In view of the existing problems of small measuring range and non-effectiveness of the existing multi-parameter gas measuring instrument, a special gas measuring instrument for mine emergency rescue was developed by researching the multi-parameter gas measuring technique, and the existing underground wireless mesh network and ring switch , The scene real-time environmental data transmission to the ground command center; through the study of “explosion triangle ” principle, the data analysis, in the command center host directly shows the concentration of O2, CH4, CO and temperature values, and shows “Explosion triangle ” graphics and the composition of the gas composition of the coordinate point, near or to the warning line when the sound and light alarm. The system can realize the real-time monitoring of high concentration underground environmental information, which is of great significance to avoid secondary disasters and improve the safety of ambulance.
