The invention discloses a signal prompting device, which comprises a controller, a first support frame and a traffic signal lamp, and is characterized in that the traffic signal lamp is connected with the controller, and the controller is used for controlling the traffic signal lamp; the device further comprises a second supporting frame, a signal projection device and a height measuring device. The signal projection device and height measuring device are both connected to controller, and height measuring device is used for measuring height of vehicle passing through second supporting frame and sending measured height signal to controller. When the controller obtains that the height difference H of two vehicles continuously passing through the second supporting frame is larger than a set height difference threshold value h through comparison, the controller can control the signal projection device to project a traffic signal image synchronous with the traffic signal lamp to the position of the vehicle firstly passing through the second supporting frame. According to the invention, the vehicle passing behind can observe the display state of the traffic signal lamp which is currently shielded by the front vehicle, so that the vehicle behind can make a judgment in advance, and the traffic safety is greatly improved.
本发明公开了一种信号提示装置,包括控制器、第一支撑架及交通信号灯,所述交通信号灯与控制器相连接,所述控制器用于控制交通信号灯;还包括第二支撑架以及信号投射装置、测高装置;所述信号投射装置和测高装置均连接到控制器上,所述测高装置用于测量通过第二支撑架的车辆的高度并将所测得的高度信号发送到控制器上,当控制器通过比较得出连续通过第二支撑架的两辆车辆的高度差H大于设定的高度差阈值h时,控制器能够控制信号投射装置向首先通过第二支撑架的车辆的位置投射与交通信号灯同步的交通信号图像。本发明能够让后面通过的车辆能够观察到当前被前车所遮挡的交通信号灯的显示状态,保证后车能够提前进行判断,大大提高了交通安全性。
