【摘要】：井下有毒气体对工作人员具有多种危害,有毒气体的实时监测对对保护工作人员的生命安全具有重要意义。目前监控终端测量准确度不足、结构复杂、功能不足,同时,有线通信的布线问题也为井下安全埋下了隐患。本文简要介绍了一种基于无线通信的分布式有毒气体监测系统,重点描述了基于STM32和NDIR传感器的检测终端,分析了有毒气体浓度检测方法及实验方法,给出了有毒气体的检测终端的硬件电路和软件流程。实验证明,该监测终端设计简单、功耗低、工作可靠、并具有较高的准确度,具有一定的市场推广价值。
[Abstract]:The underground poisonous gas has many kinds of hazards to the workers, and the real-time monitoring of the toxic gas is of great significance to the protection of the safety of the workers.At present, the measurement accuracy of the monitoring terminal is insufficient, the structure is complex and the function is insufficient. At the same time, the wiring problem of the wired communication also buries the hidden trouble for the underground safety.In this paper, a distributed toxic gas monitoring system based on wireless communication is briefly introduced. The detection terminal based on STM32 and NDIR sensors is described, and the detection method and experimental method of toxic gas concentration are analyzed.The hardware circuit and software flow of the toxic gas detection terminal are given.The experimental results show that the monitoring terminal is simple in design, low in power consumption, reliable in work, and has high accuracy, and has a certain value of market promotion.
