摘要
为满足煤矿激光甲烷传感器的低功耗及抗电磁抗干扰的新要求,设计一种基于 TDLAS 原理的激光甲烷传感器,通过硬件电路设计增强传感器的电磁抗干扰能力,采用软件设计、逻辑控制、硬件设计结合的方式实现传感器的超低功耗。传感器通过国家检测中心检验,整机功耗仅为 1.08 W;2 级电磁辐射抗扰度、脉冲群抗扰度、浪涌(冲击)抗扰度实验,评价等级均为A 级。该研究为矿用激光甲烷传感器的设计提供新的思路。
In order to satisfy the new requirements of low power consumption and anti-electromagnetic interference of laser methane sensor for coalmine,a laser methane sensor based on TDLAS principle was designed in this paper.The electromagnetic anti-interference ability of the sensor is enhanced through designing its hardware circuit,and its ultra-low power consumption is realized by the way of combining software design,logical control and hardware design.After tests by the national inspection center,its power consumption is only 1.08 W,its rating is A through the level 2 experiment of electromagnetic radiation immunity test,impulse group immunity test,and surge immunity test.This study provides a new idea for the design of laser methane sensor for mine.
