摘　　要：目前,我国沼气工程发展已初具规模,但系统对人工的依赖性较大,机械化、信息化、智能化水平较低,系统故障诊断滞后,现场操作有一定的危险性。目前,多参数监测、多种传感器融合、多种控制方式并存、增温保温技术的研发与应用已成为今后农村沼气工程发展的趋势。基于上述突出问题,尝试采用农业物联网、PLC、云触摸屏、APP等现代农业信息技术,利用空气能和太阳能清洁能源,提出了一种多功能互补型沼气干发酵反应器增温装置物联网控制系统解决方案。At present,although there is suitable scale in our country in the methane project,the system is proved to be bad real-time capability,low information sharing,labor intensive personnel and low use of agricultural waste. The system fault diagnosis is depended on worker＇s experience,so the efficiency is low,the reliability is bad and the safety is no insurance. The development and application of technologies of multi-parameter monitoring and diagnosis,multi-sensor fusion,various control strategy and temperature control has become the development trend of developing biogas project in China rural. Based on the problems in the process of methane project in China,and with technologies of Internet of things（ IOT）,logic controller（ PLC）,touch panel,cloud technology and APP,the key technology is researched and resolving scheme is put forward in the paper.
