摘要
采用基于ARM Cortex–M3内核的主流产品STM32系列单片机作为微控制器和SIM900A模块作为通信芯片,设计完成一套车载通讯系统。在SIM900A模块AT指令系统基础上,实现了车载终端的语音播报与通话功能,并通过串口完成SIM900A与微控制器的数据传输。利用GPRS无线网络进行远程数据传输,对车辆的行驶状况和驾驶员的工作状态进行实时监控与预警,对大幅降低交通事故具有积极意义。
Using STM32 MCU from ARM Cortex -M3 core as the microcontroller and SIM- Corn＇s SIM900A module as a communications chip, a vehicle-mounted communication system is designed. Based on SIM900A＇s AT command system, the vehicle terminal voice broadcast and communication are achieved. And the data transmission between SIM900A and microcontroller can be accomplished through the serial ports. With GPRS wireless network, real-time monitoring of the working condition of both the driver and the vehicle can be carried out and thus early warning can be made to significantly reduce traffic accidents.
