摘要
根据电子信息系统环境要求,互联网数据中心(IDC)环境检测系统不仅实现室内温度、湿度和空气中氢气密度与烟雾浓度环境数据的检测,还可以通过无线网络将检测信息上传,与工作人员保持联系,从而在有人值守的情况下,保障互联网数据中心内各设备的安全可靠运行。检测系统以STM32为核心,选用的传感器包括温湿度传感器DHT21、温度传感器AD590、氢气密度传感器MQ-2和烟雾浓度传感器MQ-8,输入输出设备采用触摸屏,并利用无线通信模块TC35与手机短信息连接。
According to environmental requirements of electronic information systems, the environmental monitoring system of In- ternet data center （IDC） not only can achieve the environmental data detection of the indoor temperature, humidity and the density of hydrogen and smog in the air, but it convey the monitoring information through the wireless network, keep in touch with staff, so in the cases with attendant it can protect the safe and reliable operation of the equipments which are in the Internet data cen- ter. The monitoring system is based on STM32 core and uses sensors which include temperature humidity sensor DHT21, tempera- ture sensor ADS90, hydrogen gas density sensor MQ-2 and smoke concentration sensor MQ-8,the input and output device is touch screen, and connect with cellphone short message though wireless communication module TC35.
