基于北斗通信的WSN區(qū)域監(jiān)測系統(tǒng)數(shù)據(jù)傳輸技術(shù)研究
[Abstract]:Various natural disasters have obvious regional characteristics, that is, the monitoring points are many, the monitoring points are scattered and the area of the monitoring area is large, but the traditional monitoring system can not meet the monitoring requirements. The wireless sensor network (Wireless SenSor Network, WSN) monitors the environment or object information in real time through the end of various sensors, through the embedded system. The information is processed by the system and the information is transmitted to the user terminal by the multi hop route by the self organizing wireless communication network. The data acquisition and transmission can be realized in the scattered area of the monitoring point, but the data should be transferred to the monitoring center with the help of other remote communication technologies. The Compass Navigation Satellite System, C NSS) the signal covers the territory and the surrounding area, and has the short message communication function. It is safe, reliable, stable and secure. It is suitable for the long distance transmission of data. Combined with the above three backgrounds, this paper combines the near distance data transmission technology of wireless sensor network with the remote data transmission technology of CNSS short message communication. In the area monitoring system, the WSN regional monitoring system based on the Beidou communication is researched and designed. First, the whole architecture of the WSN regional monitoring system based on the Beidou communication is constructed, and the feasible way for the application of the WSN and Beidou satellite system in the area monitoring field is explored. Secondly, the regional monitoring subsystem of the regional monitoring system is based on the regional monitoring subsystem. The system has carried on the system overall structure design, the hardware design and the software design. Thirdly, based on the thorough understanding of the process of the Beidou satellite communication, the characteristics and the detailed analysis of the monitoring data transmission mode, the data transmission mechanism suitable for the regional monitoring system is put forward, and the corresponding application layer communication protocol is given. At the same time, the application of the single communication protocol is given. The chip machine is designed and developed the gateway (data protocol converter) to realize the transparent data transmission of the WSN regional monitoring subsystem and the Beidou communication system. Fourthly, the requirement of the design of the monitoring software for the general host computer is analyzed, and the features of the WSN region monitoring based on the Beidou communication are combined, and the upper part of the computer is designed by the modular design idea. The software modules and workflow are designed, and on this basis, serial communication, Access database and ODBC database drive are integrated and developed in the Labview environment. 5, the functional modules of the system are tested, and the results are analyzed, and the feasibility of the system is confirmed.
