高速公路防追尾撞车告警装置

Alarming device capable of preventing rear-end collision on expressways

Abstract

The invention discloses an alarming device capable of preventing rear-end collision on expressways, which comprises an acceleration sensor module, a microprocessor and a wireless module. The acceleration sensor module is mounted in every vehicle and used for acquiring acceleration of the vehicle in real time, the microprocessor is mounted in every vehicle, and the wireless module is mounted in every vehicle and used for receiving and transmitting alarming control signals outputted by the microprocessor of the vehicle, and sending out wireless alarming signals to vehicles nearby. The wireless module is further used for receiving surrounding wireless alarming signals transmitted by the wireless modules of the vehicles nearby and extracting sequence values of the surrounding wireless alarming signals to output the sequence values to the microprocessor of the vehicle. Using the alarming device quick in responding speed needs no information transmission through a base or third platform, and the alarming device is high in sensitivity and capable of alarming the following vehicles as soon as possible, so that chain collision on expressways can be prevented effectively.
本发明公开了高速公路防追尾撞车告警装置,它包括安装在每辆车内的加速度传感器模块,该加速度传感器模块用于实时采集本车的加速度;安装在每辆车内的微处理器;安装在每辆车内的无线模块,该无线模块用于接收本车的微处理器输出的告警控制信号和转发控制信号,然后向附近车辆发出无线告警信号;并且该无线模块用于接受附近车辆的无线模块发出的周围无线告警信号并提取周围无线告警信号的次序数值输出给本车的微处理器。采用本装置响应速度快,无需通过基站或第三方平台进行信息传输,灵敏度高,能第一时间告警后续车辆,有效的防止了高速公路上的连环撞击。
