摘要
为解决基于裸机的传统车辆状态监测系统的控制单一、效率不高和能耗高等问题,设计一种基于FreeRTOS的车辆状态监测系统。该系统采用STM32F103RCT6控制器,在其上搭建数据采集、NB-IoT通信等外设电路;软件实现基于FreeRTOS实时操作系统,根据车辆状态监测系统中各种操作要求划分各个任务的优先级,确保系统实现对车辆状态参数实时监测,同时采用tickless模式降低系统功耗。经实验测试,系统可为用户提供车辆状态实时数据,具有多任务、低功耗、实时性、模块化和高可靠性等优点,达到了设计目的。
In order to solve the problems of single control, low efficiency and high energy consumption of the traditional vehicle condition monitoring system based on bare metal, a vehicle condition monitoring system based on FreeRTOS is designed. The system adopts STM32 F103 RCT6 controller, on which peripheral circuits such as data acquisition and NB-IoT communication are built. Software implementation is based on FreeRTOS real-time operating system, which divides the priority of each task according to various operating requirements in the vehicle condition monitoring system, ensuring that the system can monitor the vehicle condition parameters in real time, and adopting tickless mode to reduce the system power consumption. The experimental test shows that the system can provide users with real-time data of vehicle status, and has the advantages of multi-task, low power consumption, real-time, modularization and high reliability, thus achieving the design purpose.
