[Abstract]:District central heating, as the main heating scheme in northern cities of China, plays an important role in keeping the daily life warm in winter and reducing environmental pollution. However, due to poor operation and maintenance of heating equipment, such phenomena as "insufficient heating" and "excessive heating" often result in unreasonable use of heat energy and affect the quality of winter life of the people. In order to solve the above problems, most of the problems are solved by the on-site operation of the operation manager, which takes up more human resources and has the non-convenience of operation. In order to solve the above problems, In this paper, the urban heating node monitoring system based on cloud service is designed. The system mainly uses the Android client as the monitoring terminal, with the help of the data storage and forwarding function of the cloud server, realizes the data exchange with the underlying embedded Android device, and simulates the water temperature of the heating node in the city. Monitoring and control of pipeline water pressure and other information. The system can replace the traditional field operation. The operator can monitor and control the heating nodes within any network accessible range through the Android client program. Client program can not only display the current node data in real time, but also provide historical data query function. At the same time, if the heating node data does not conform to the normal working range, it can also be adjusted through Android client, and finally achieve the desired results. In addition, the video monitoring function of heating node is added, and the instrument data of heating node can be displayed in real time on Android client. In the design verification and implementation, Android client is implemented with MVP architecture, highly decoupled, and the code function level is clear, which not only completes the function required in this project, It also uses custom view in many places, which improves the beauty of application interface and convenience of operation. At the same time, it follows the software development specification and uses git version control tools to manage and so on. The cloud server hardware hierarchy uses the Ali cloud, in which the lamp environment is configured. The server development language uses PHP, and the development framework is think PHP, which takes MySQL database as the data storage medium, and provides API interface to Android client program and embedded Linux device. The function of data storage and exchange between Android client and embedded Linux device is realized. The embedded Linux device is based on the Mini2440 development board. It is connected with temperature sensor, relay, DC motor AD converter circuit and USB camera. It provides the analog data source and analog control peripheral of the system. At the same time, the video transmission between Android client and mjpg-streamer is realized by transplanting mjpg-streamer into embedded Linux device. Starting from the requirement background of the whole system, this paper introduces in detail the basic knowledge and the selection of hardware and software platform, the selection of each module architecture and the concrete implementation method. From the design of Android client to the design of cloud server and then to the design of embedded device, it not only covers the function module and interface interaction, but also relates to the extensibility, maintainability and security of software development. Finally, through the test and optimization of the system, the content of the project is verified. At the same time, the system has good real-time and security, and can meet the actual needs in a large extent.
