摘要如今,全世界卫星通信系统的发展呈现三足鼎立的态势。除了美国的全球定位 系统(GPS)和俄罗斯的格洛纳斯卫星导航系统(GLONASS)这两个成熟的卫星 导航系统之外,还有目前正在飞速发展的中国自主研发的北斗卫星导航系统。而随 着卫星导航系统在我国的蓬勃发展,拥有自主知识产权的北斗卫星导航系统也逐渐 步入成熟的阶段,整个系统可以提供给用户全天候、高精度、快速实时定位的服务, 同时该系统也具有数字报文通信,精密授时等功能。更重要的是北斗卫星导航系统 是国家大力推广应用的通信系统,也使得基于该系统的相关研发产品也得到了大力 的推广。80380
本次课题所设计的系统就是北斗通信系统的一个典型的应用。通过采集模块采 集数据,利用北斗通信模块进行数据通信。其中系统用到的北斗模块是北斗客户机 TS8510,同时以 51 单片机为数据采集端,通过串口通信的方式来进行数据的传输。 整个系统实现的功能有实时定位、数据采集和数据通信,使用到的模块有 DS18B20 温度传感器、AD-DA 芯片(PCF8591)和 HC-SR04 超声波测距模块。在北斗通信协 议的支持下,硬件模块与对应的功能程序代码相结合,形成一套完整的数据采集处 理系统。

Abstract Nowadays, the development of the navigation satellite system in the world is a situation of tripartite confrontation。 In addition to America's global positioning system (GPS) and Russia's GLONASS navigation satellite system (GLONASS) which are well-rounded communication system, the Beidou Satellite Navigation System (BDS) is also in a rapid development。 And with the rapid development of the BDS in China, the BDS with independent intellectual property rights is entering the mature stage。 So the BDS can provide the position services all the time and the services are fast and with high precision。 And at the moment the BDS can also provide the services of digital communication message and precise timing。 Above all, the BDS is a communication system which is strongly supported by the state, and it makes the product based on the BDS have a good prospect。
In this project the system is a typical application based on the BDS。 The system collects the data by the data acquisition module and corresponds with the BDS by the communication module。 And the communication module is the Beidou client TS8510, the data acquisition module is MCS51。The way of communication is serial port communication。 Also, the function of the system are real-time positioning, data acquisition and the data communication。 And the data acquisition module is combined with the AD-DA chip PCF8591, HC - SR04 ultrasonic ranging module and the DS18B20 temperature sensor。 With the support of the Beidou communication protocol, the hardware combines with the software to form the data collection and communication system。
Keywords: Beidou satellite navigation system;MCS51;Serial communication。
