Abstract:According to the structure of the internet of things,the monitoring and warning system of rural marsh gas based on Internet of things was proposed for the safely using of rural biogas energy and effective management. The hierarchical network architecture of the system was designed with the sensing layer, transport layer and application layer. The wireless sensor network technology was used to realize marsh gas environmental parameter acquisition in the sensing layer. The GPRS technology was used to complete the wireless transmission of the marsh gas environmental parameter in the transport layer. The data monitoring center software in the application layer realized remote monitoring and operation of the system. The development of this system will provide technical support to realize the information and network monitoring of large-scale marsh gas in rural areas,and has wide application and prospects of promotion.

沼气作为一种新型的清洁能源,在我国新农村建设中得到了快速推广和应用,并取得了一定的经济效益、社会效益和区域环境效益。随着农村用户对沼气需求的快速增长,沼气工程实施规模也随之增大,沼气的产气效能和安全使用管理将成为非常突出的问题[1,2]。用户管理不善和技术操作失误可能导致沼气池产气率较低。此外,沼气池的长期使用可能导致沼气池及输气管道出现漏气。沼气是一种以甲烷和二氧化碳为主要成分的可燃性混合气体,若管理不善,容易造成气体蓄积,当达到一定浓度后,若泄漏会造成人员中毒,遇明火则极易产生爆炸,造成伤亡事故,对人民群众的人身和财产安全造成危害。因此,建立一种高效的、网络化的农村沼气工程监测预警平台,对安全利用沼气能源,提高沼气利用监管效率和服务质量,具有非常重要的现实意义。……
