为了促进公交系统的规范管理,实现公交系统的远程监控,设计了一款基于STM32F103VCT6和μC/OS-II嵌入式实时操作系统的智能监控终端。详细分析了系统功能并给出系统总体设计方案,介绍了各个功能模块的原理及具体实现,具体说明了μC/OS-II操作系统下,系统内核中多任务的切换及实现。测试结果表明,该系统通过GPRS业务平台的数据的实时采集与传输,达到了公交车辆的远程监控功能。
In order to promote the standardized management of public transportation system and realize the remote monitoring of public transportation system, an intelligent monitoring terminal based on STM32F103VCT6 and μC / OS-II embedded real-time operating system was designed. The function of the system is analyzed in detail and the overall design of the system is given. The principle and implementation of each function module are introduced. The switching and implementation of multitasking in the system kernel under the μC / OS-II operating system are described in detail. The test results show that the system real-time acquisition and transmission of data through the GPRS business platform to achieve the bus remote monitoring.
