[Abstract]:With the development of information technology, wireless sensor network (Wireless Sensor Network,WSN) has been paid more and more attention in the smart home. Power equipment management and intelligent monitoring have been widely used. There are many nodes in WSN. How to control the topology of nodes and make sensor networks transmit data efficiently; How to combine WSN with the existing communication network according to the actual working environment to realize the remote transmission of data, and how to receive and process the real-time data by the server are all the emphases of the WSN research. Due to the lack of open source protocol stack, most of the WSN routing research is through theoretical analysis or simulation to improve the routing algorithm, less through hardware implementation and actual testing. The rationality and correctness of the algorithm need the combination of theory and practice. Based on the analysis of the existing WSN routing algorithms, the hardware implementation method of the routing algorithm based on the Msstate PAN protocol stack is studied in this paper, and the hardware routing algorithm is tested in the practical application. The Msstate PAN is transplanted to the general CC2530 platform, and the inherent routing algorithm and network networking are realized by programming. In the practical application environment, the hardware test of the key parameters of routing algorithm affecting the network performance is carried out, and the selection basis and rule of the key parameters of routing are analyzed, and the influence of different topology structures on the network performance is analyzed by changing the topology structure of the network. Finally, the application experiment is carried out in the substation field. Aiming at the problem of single communication mode and poor flexibility of wireless sensor network gateway, an adaptive WSN monitoring system gateway is designed and implemented. The gateway can select Ethernet and WiFi, according to the working environment. A method of GPRS communication to transmit data from a wireless sensor network. STM32F107, with 32-bit processor has the advantages of high speed, large chip capacity and many external resources. It can meet the needs of system development. By designing processor module, peripheral Zig Bee module, GPRS module, etc. The interface circuit of the WiFi module completes the hardware development of the gateway system; Software development mainly involves the transplantation of TCP/IP protocol stack, the selection and control of various communication modes and the transmission and reception of data. Finally, the performance of the gateway is tested by setting up the temperature and humidity monitoring experiment system. The results show that the gateway has the characteristics of flexible expansion, high reliability and easy to use. Finally, the upper computer software is developed on the server side based on Socket, which realizes the functions of receiving, storing and querying the data, and can deal with the WSN data effectively.
