摘要
介绍一款以ARM Cortex-M3为核心的卫星定位系统的实际设计;设计使用意法半导体公司的STM32F1 03CBT6为微控制器,NemeriX公司的NJ1836为GPS接收模块以及西门子公司的MC55作为GPRS/GSM网络通信模块;软件平台采用实时操作系统μC/OS-II,对系统软件进行模块化设计;测试中使用高性能锂电池,待机时间长达200小时,室外搜星时间低于10秒,远程操控性能良好;该系统硬件电路简单,软件功能完善,体积小,精度高,价格低廉,使用方便。
Introduce an ARM Cortex-M3 core of the actual design of the satellite positioning system. The design use STM32F103CBT6 of STMicroelectronics as a micro controller, NemeriX＇s NJ1836 as a GPS receiver module and Siemens MC55 GPRS / GSM as a network communication module. Software platform with real-time operating system C/OS-Ⅱ, the modular design of the system software. In the tests, system use high-performance lithium battery, battery time up to 200 hours, the stars search time of less than 10 seconds in the out-door, and the remote monitoring performance is good. This system has the advantage of simple circuit of the hardware, perfect function of the software, small size, high precision, low cost, easy to use.
