Abstract：In view of the fact that after an accident occurs in a long expressway tunnel， the casualties are large and the follow-up vehicles cannot understand the road conditions ahead in time， it is easy to cause secondary accidents. This paper designs a highway tunnel accident alarm device with early warning capability， and mainly introduces the structure of the device And working principle.The device can effectively reduce the damage of the colliding vehicle and personnel， and through the dual impact of vision and hearing， the rear driver can study and judge the situation inside the tunnel in advance， reduce the vehicle speed in time， and avoid the occurrence of secondary accidents.

The device can effectively reduce the damage of the colliding vehicle and personnel， and through the dual impact of vision and hearing， the rear driver can study and judge the situation inside the tunnel in advance， reduce the vehicle speed in time， and avoid the occurrence of secondary accidents.

該装置可有效减少碰撞车辆和人员的伤害，并且通过视觉和听觉的双重冲击，后方驾驶员可以预先研究和判断隧道内的情况，及时降低车速，避免发生事故。二次事故。
