The invention discloses a tunnel entrance vehicle speed prompting system. Visibility in a tunnel is collected through a visibility sensor; the first speed sensor collects the first speed of the front vehicle; the first image acquisition device acquires a first state image of a front vehicle; the second speed sensor collects the second speed of the rear vehicle; the second image acquisition device acquires a second state image of the rear vehicle; the data processing unit judges whether the front vehicle and the rear vehicle collide or not according to the tunnel visibility, the first vehicle speed, the first state image, the second vehicle speed and the second state image; and the safe vehicle speed is calculated. The data processing unit can judge whether the front vehicle and the rear vehicle are collided or not under the influence of the black hole effect, the safe vehicle speed of the rear vehicle when the two vehicles are not collided is calculated, and the safe vehicle speed is displayed through the speed display unit. The safe vehicle speed displayed by the speed display unit is not fixed, but the safe vehicle speed of the rear vehicle is regulated and controlled according to different conditions at the entrance of the tunnel.
本申请公开了一种隧道入口车速提示系统,通过能见度传感器采集隧道内的能见度;第一速度传感器采集前车的第一车速;第一图像获取装置采集前车的第一状态图像;第二速度传感器采集后车的第二车速;第二图像获取装置采集后车的第二状态图像;数据处理单元根据隧道能见度、第一车速、第一状态图像、第二车速、第二状态图像判断前车和后车是否会相撞;并计算安全车速。本申请的数据处理单元可以判断在“黑洞效应”的影响下,前车和后车是否会相撞,并计算两车不会相撞时后车的安全车速,并通过速度显示单元进行显示。速度显示单元显示的安全车速不是固定的,而是根据隧道入口处不同情况对后车的安全车速进行调控。
