【摘要】：各种自然灾害发生具有明显的区域性特点,即监测点多、监测点分散和监测区域面积大,而传统的监测系统一般不能满足其监测需求。无线传感器网络(Wireless SenSor Network,WSN)通过各类传感器终端实时监测环境或对象的信息,通过嵌入式系统对信息进行处理并通过自组织无线通信网络以多跳路由方式将信息传送到用户终端,可以实现监测点分散区域的数据采集传输,但是需借助其它远距离通信技术将数据传输到监控中心。北斗卫星系统(Compass Navigation Satellite System,CNSS)信号覆盖我国领土及周边地区,同时具备短报文通信功能,安全、可靠、稳定、保密性强,适合数据的远距离传输。结合上述三个背景,本论文将无线传感器网络的近距离数据传输技术与CNSS短报文通信的远距离数据传输技术相结合应用于区域监测系统,研究与设计了基于北斗通信的WSN区域监测系统。其一,构建了基于北斗通信的WSN区域监测系统的整体架构,为WSN和北斗卫星系统在区域监测领域的应用探索了可行的途径;其二,对区域监测系统的感知层WSN区域监测子系统进行了系统的总体结构设计、硬件设计与软件设计;其三,在深入了解北斗卫星通信的流程、特点以及详细分析监测数据传输方式的基础上,提出了适用于区域监测系统的数据传输机制,并给出了相应的应用层通信协议,同时,采用单片机技术设计与开发了网关(数据协议转换器),实现WSN区域监测子系统与北斗通信系统的数据透明传输;其四,在对通用上位机监测软件设计的需求进行分析,结合基于北斗通信的WSN区域监测自身的特点,采用模块化的设计思想,对上位机软件的软件模块与工作流程进行了设计,并在此基础上采用串口通信、Access数据库、ODBC数据库驱动等技术手段在Labview环境下集成开发而成的。其五,对系统的各功能模块进行了测试,并对结果进行分析,证实了系统的可行性。
[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.
