摘要：我国人口众多，资源消耗巨大，能源短缺严重。沼气是一种理想的新型可再生能源，具有很高的经济效益和生态效益，合理地开发利用沼气能源具有极其重要的意义。但目前我国农村沼气利用还不是很多，沼气池管理系统还存在较多问题，比如池内发酵效率的提高、系统安全性的保障等都不可忽视。本设计是能够为多用户同时提供在线服务的沼气池无线远程监控系统，采用STM32作为主控芯片，通过多传感器数据采集终端，对沼气池内甲烷浓度、温湿度、PH值等进行监测；而后通过基于4G无线通信网络的云技术分析现场数据，对沼气池内各项指标进行综合评价，以便允许授权的用户通过多种移动终端（如手机、PC等）掌握实时数据，实现远程监控。

Abstract： Our country has a large population which results in a relatively shortage of energy and huge consumption of resources. As a renewable energy， the development of biogas energy has a broad space on the economic and ecological front so that rational development and use of biogas energy has very important significance. However， at present the use of methane is still relatively small in China countryside. In turn， there are a lot of problems in biogas management system， such as improving the efficiency in fermentation process and ensuring the system security. The system designed is based on using STM32 as the main control chip，as well as the wireless remote monitoring system of methane tank can provide real-time， online services for multiple users. People can collect and monitor the information of temperature and humidity， Methane concentration and pH-value in the monitoring environment by wireless sensor network technology. Then through the 4G wireless communication network cloud technology， it can analysis method and online data， giving a synthetical and overall evaluation of each index. Allowing authorized users through a variety of mobile terminal （such as mobile phone， PC， etc.） to master the real-time data， achieving remote monitoring.

1 概述

当前，随着社会经济生活的不断发展，对能源资源消耗巨大，传统能源将越来越少。新能源沼气技术不仅能解决群众生活用能的问题，也可以降低对传统能源的依赖，保护生态环境，有效改善人们的生活质量，促进当地经济可持续发展，因而在全国范围内得到了大力推广[1]。为了能顺利地解决众多能源问题、顺利地使农村地区走上可持续型发展道路，合理地开发和利用农村能源将具有极其重要的意义[2]。但因沼气使用的自动化程度和安全性不高，广大农户的使用情况并不理想。……
