沼气作为一种可再生的清洁能源，其在农村的应用日益广泛，但其安全性也成为影响推广的一个重要问题。 近年来，对于沼气工程运行管理的监控已经成为沼气行业中一个重要的问题。物联网是一种新兴的信息技术，可以基于传感 技术、传感网络实时获取运行现场的各类数据，在沼气工程运行监控中可以发挥重要的作用。然而，综观近年来的研究和实践 可以发现，用于实际运行的沼气工程运行监控系统仍处于研究的初级阶段。本文从北京市农业局沼气工程运行管理智能监控 的实际需求出发，基于物联网技术设计、实现了沼气工程运行管理智能监控系统，并在北京市进行了具体部署，实际结果表明， 该系统具有良好的应用效果。

As a kind of renewable clean energy, biogas is widely used in rural areas, but its security has become an important issue of the promotion. In recent years, the monitoring of the operation and management of biogas project has become an important problem in the industry. The Internet of Things is a new kind of information technology, which can be based on the sensing technology, the sensor network real-time access to all kinds of data, and can play an important role in the operation of biogas project monitoring. However, in recent years, from the research and practice, we can find that the actual operation of the biogas project monitoring system is still in the primary stage of research. In this paper, based on the actual needs of the operation and management of the Agricultural Bureau of Beijing Agricultural Bureau, the intelligent monitoring system for the operation and management of biogas project is designed and realized. The practical results show that the system has good application effect.
