The invention discloses a vehicle collision emergency alarm calling device, and relates to the technical field of intelligent traffic management. The device comprises an accident alarm system, the accident alarm system comprises an alarm base station, a signal repeater, a field alarm system, a remote controller and a monitoring center. The field alarm system comprises a plasma laser transmitter, a laser diffusion device, a projector, a control box and a fog screen machine, the plasma laser transmitter and the projector are installed at the arch crown of a tunnel portal, the laser diffusion device is installed at the head of the laser transmitter, the control box and the projector are electrically connected with the monitoring center, and the fog screen machine is laid along the secondary linings of the tunnel portal. Based on a Zigbee wireless communication networking technology, a series of wireless alarm base stations and a field alarm system outside the tunnel are arranged in the tunnel, a laser virtual wall is formed at the tunnel portal by adopting a laser technology, traffic accident image information in the tunnel is displayed on the virtual wall, vehicles outside the tunnel are warned not to enter the tunnel any more, and secondary accidents are prevented.
本发明公开了一种车辆碰撞紧急报警呼叫装置,涉及智能交通管理技术领域,包括事故报警系统,事故报警系统包括报警基站、信号中继器、现场报警系统、远程控制器和监控中心,现场报警系统包括等离子激光发射器、激光扩散装置、投影机、控制箱以及雾幕机,等离子激光发射器和投影机安装在隧道入口拱顶处,激光扩散装置安装在激光发射头部,控制箱和投影机与监控中心电连接,雾幕机沿着隧道洞口二衬上铺设。本发明基于Zigbee无线通信组网技术,通过在隧道内布置一系列无线报警基站和隧道外现场报警系统,采用激光技术在隧道洞口形成一道激光虚拟墙,将隧道内的交通事故图像信息显示在虚拟墙上,警示隧道外部车辆不再进入隧道,防止二次事故的发生。
