In order to solve the problems of weak anti-interference ability and low indoor air purification detection accuracy of the indoor air monitoring system in the power communication room, the indoor air monitoring system of power communication room based on ARM is designed to improve the detection accuracy of indoor air purification. Air temperature monitoring is realized by using DHT11 temperature sensor,special digital unit acquisition technology and temperature sensor technology. Install HS1101 sensors to monitor air humidity. Using OLED liquid crystal display as the visual window of the system,the design of power com-munication room monitoring system is completed. The experimental results show that the system has low energy consumption and strong anti-interference ability,which plays an important role in the accurate detection of indoor air purification.%为解决当前电力通信机房室内空气监控系统抗干扰能力弱,室内空气净化检测精度低等问题.设计了基于ARM的电力通信机房室内空气监控系统,以提高室内空气净化检测精度.选用DHT11温度传感器,引入专用数字单元采集技术和温度传感技术,实现空气温度监控.安设 HS1101传感器,监控空气湿度.采用OLED液晶显示作为系统的可视化窗口,完成电力通信机房监控系统设计.实验结果表明,该系统能耗低,抗干扰能力强,为准确检测室内空气净化程度起到重要作用.
