摘　　要：管道输送乙二醇时,需要检测其是否泄露。采用液位传感器测量乙二醇液位,同时根据乙二醇影响空气温度和湿度的性质,辅以温湿度传感器测量周围空气的温度和湿度,采用GSM MODEM进行无线传输实现数据交互,采用STC12C5412AD单片机作为系统的控制单元。实验表明系统工作准确可靠,操作方便,对于检测具有稳定化学性质的液体和气体具有参考价值。As it conveyed by the tunnel,there needs to check whether it is leaking or not.In order to achieve the goal,it should be detected the level of ethylene glycol with level sensors.Then,as the humidity and temperature in air are influenced by ethylene glycol,they should be detected with corresponding sensors as an auxiliary way.The GSM MODEM is used to exchange data wirelessly and the microcomputer STC12C5412AD is used as the controller for the system.Experimental results show that the system is accurate,reliable and convenient with reference value in detecting some kinds of liquid or gas with stable properties.
