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。
The underground toxic gas with a variety of hazards to the staff, has the important meaning of life safety real-time monitoring of toxic gases on the protection of staff. At present, monitoring terminal have low accuracy,structure complex,functional deficiency, at the same time, the wiring problem of cable communication is also a hidden trouble for underground security. This paper introduces a distributed gas monitoring system based on wireless communication, emphasize describes the detection terminal based on STM32 and NDIR sensors, the concentration of toxic gases is ana-lyzed, concentration detection method and Experimental method, the hardware circuit and software flow of detection ter-minal are given the detection of toxic gases. The experiment has proved, This monitoring terminal has the advantages of simple design, low power consumption, reliable operation, and has high accuracy, has a certain market value.
