新型矿用便携式可组网烟气监测分析仪的研制

摘要

In order to solve problems that portable smog analyzer based on electrochemical sensor has poor flexibility and universality, and portable optical fiber smog analyzer can not achieve data remote transmission and multi-sensor networking, a novel mine-used portable smog analyzer with networking function was designed. Monitoring and analysis circuit for smog was designed based on AvaSpec-2048 in order to detect smog concentration. Networking function of the analyzer was realized by embedded development technology and ZigBee wireless network technology. The test results showed that the analyzer has characteristics of stable and reliable working, fast response, strong networking capability, which can well meet with requirements of distributed multi-instrument monitoring.%针对现有以电化学传感器为主的便携式烟气分析仪存在灵活性和普适性差,便携式光纤烟气分析仪无法实现数据远程传输和多传感器联合组网的问题,研制了一种新型矿用便携式可组网烟气监测分析仪.基于AvaSpec—2048设计了烟气监测分析电路以对烟气成分气体的体积分数进行高精度检测,采用嵌入式开发技术和ZigBee无线网络技术实现了分析仪的组网功能.测试应用结果表明,该分析仪工作稳定可靠,响应速度快,组网能力强,能很好地满足分布式多仪表联合监测的要求.
