摘要
针对矿用瓦斯检测系统中使用传感器的特点以及工作环境,加入温度、湿度数据采集环节,在软件算法方面提高测量准确度。设计中主要采用高共模抑制比的差分放大电路、开关电容滤波器提高信号源的精确度,同时抑制电源噪声以提高系统抗干扰性。
This mine gas detection system added temperature and humidity sensor to adapt mine gas detection sensor and coal environment,and use a program to improve veracity.The new system use differential amplifier and switched-capacitor filter to improve veracity of the signal source,and restrain power noise to enhance anti-interference of the system.
