[Abstract]:With the development of Internet of things (IoT) technology, intelligent monitoring technology is increasingly deepening into people's daily life, and plays an increasingly important role in various sectors of society. At present, the traditional monitoring technology can not meet the needs of users because of its passive, poor real-time, poor man-machine interaction and other characteristics. Intelligent monitoring uses advanced integrated cabling, network communication, multi-node sensor networking and audio and video technology to connect all the monitoring devices together, and to build a monitoring network that is convenient and safe, and can upload all the data to the cloud. The data is stored and analyzed in the cloud, and then the interface is provided in the cloud. Various clients can download and display the data in the appropriate way. Based on the above background and the key science and technology project of Jilin Provincial Science and Technology Department, this paper designs a set of intelligent monitoring system with perfect function, including the development of ZigBee wireless sensor network and Android mobile phone and the design and implementation of related middleware. This system is divided into four parts: data acquisition terminal PC end, server end and Android phone terminal. At the data acquisition end, the fire information sensor selection and signal extraction and processing are realized, and the self-organized ZigBee wireless sensor network platform is established to ensure reliable and efficient data transmission. As the middleware of communication between ZigBee coordinator and cloud server, on the one hand, PC communicates with sensor network through serial port communication of PC; on the other hand, it interacts with cloud server through HTTP protocol. On the server side, the operation of the server / client network framework and the Linux kernel command line is studied, the configuration of the cloud server, the programming of the network communication interface and the construction of my SQL database are realized, so as to ensure the reliability of the data from the public network architecture. Stable transmission of services. At the Android end, the network architecture of Android is studied, and the real-time data communication between the collecting end and the server end is realized by using the JSON data exchange format; the multithread programming is studied to realize the related function in app; the network camera is studied. And embedded in app to achieve video monitoring. After the completion of the development, the various parts and the whole system were tested. The test results show that the function of each module of the system is correct, solid and reliable, the design of the whole system is reasonable, the function is perfect, and the expected effect is achieved.
