【摘要】 为降低工厂厂区车辆行驶过程中的安全风险,有效监控车辆的运行状态,基于QT开发框架和STM32系列平台研发了一套便携式的嵌入式车载终端系统样机,通过全球定位系统(Global Positioning System,GPS)报文信息解析、消息队列遥测传输(Message Queuing Telemetry Transport,MQTT)、语音合成等技术实现了车辆定位、远程速度监控及超速警报等功能。经实际道路测试,验证了样机各项功能的完整性和稳定性,能够通过移动终端监控车辆行驶状况,对超速等危险驾驶行为给予警报提醒,规范驾驶行为,降低安全风险。更多还原

【Abstract】 In order to reduce the safety risk in the process of vehicle driving in the factory area and effectively monitor the running status of the vehicle, a portable embedded vehicle terminal system prototype was developed based on the QT development framework and STM32 series platform. Through the Global Positioning System(GPS) message information analysis, Message Queuing Telemetry Transport(MQTT),voice synthesis and other technologies, the vehicle positioning, remote speed monitoring, overspeed alarm and other functions are realized.The actual road test has verified the integrity and stability of the functions of the prototype. It can monitor the driving status of the vehicle through the mobile terminal, give alarms to dangerous driving behaviors such as speeding, regulate driving behaviors, and reduce safety risks.更多还原
