基于QNX的远程车载酒驾智能监控系统

Remote vehicle smart drunk monitoring system based on QNX

随着车辆酒驾事故的频现,车载酒驾监控系统已成为现代新型车辆的核心辅助驾驶单元。由于传统酒驾监测仪主要靠呼气模式对司机进行不定期抽检,严重影响酒驾监测的实时性和便捷性。为此,提出基于QNX的远程车载酒驾智能监控系统方案,采用以实时性和安全性著称的QNX系统搭建车载终端软件平台;引入气敏性酒精传感器来实时计算以司机驾座为中心的酒精浓度;设计基于GPRS的远程无线通信系统来实时监控车辆酒驾等级。实验表明,该方案不仅能有效降低酒驾事故发生频率,而且极大提升了车辆辅助驾驶的互联性和智能性。

With the frequently accidents of drunk driving, drunk driving car monitoring system has become the core of the modern new vehicle auxiliary driving unit. The traditional drunk monitor mode depended mainly on the unscheduled breath sampling of the driver, which seriously affected the convenience and the real-time monitoring of drunk driving. In this paper, a remote vehicle intelligent monitoring system based on QNX for drunk driving was proposed, QNX, which was known as real-time and security, was used to build a car terminal software platform. Gas sensitivity alcohol sensor was introduced to calculate the driver＇s alcohol concentration in the center of the driving seat in real-time. Remote wireless communication system based on GPS was designed to monitor vehicle drunk driving level in real-time. The experiment shows that this method can not only effectively reduce the frequency of drunk driving accidents, but also greatly enhance the vehicle driver assistance interconnected and intelligent.
