Abnormal delay reminding device for traffic at road intersection

Abstract

The invention relates to an abnormal delay reminding device for queuing traffic at a road intersection. The device is composed of an HC-SR04 ultrasonic ranging sensor, a single chip microcomputer 51Cprocessor, an LCD1602 display and a buzzer. The ultrasonic sensor is smoothly fixed to an appropriate position in the front of the vehicle body (near the headlights), and the MCU, display and buzzer are installed in proper positions in the cab. The ultrasonic sensor can measure the longitudinal distance between the vehicle and the preceding vehicle, transmit the signal to the single chip microcomputer 51C, and transmit the result to the LCD 1602 display after processing and calculation, and the display displays the distance in numerical form. If exceeding the limit, the buzzer sounds to alertthe driver. The device can automatically sense the longitudinal distance between the vehicle and the preceding vehicle, and automatically remind the driver in the rear vehicle if exceeding the limit,thereby reducing abnormal traffic delays, and improving the traffic efficiency at the road intersection.

Description

technical field [0001] The invention relates to a vehicle passing reminding device, especially a device capable of automatically emitting a sound to remind a driver during the transition to a green light phase at a road intersection. Background technique [0002] In the process of queuing up at urban road intersections, normal traffic delays occur during red lights; drivers may ignore the green lights due to distraction by looking at mobile phones or other reasons, resulting in abnormal traffic delays. This greatly prolongs the waiting time of subsequent vehicles and reduces the efficiency of vehicles at the intersection. If the vehicle still does not start for a long period of time at the green light, the vehicle behind often uses its horn to remind the vehicle ahead, which increases traffic noise and sometimes causes disputes between drivers. At present, it is relatively rare to have a reminder device that comes with a vehicle. This device can be installed on the vehicle....

Problems solved by technology

If the vehicle still does not start during a long period of time when the green light is green, the vehicle behind will often use the horn to remind the vehicle in front, which increases traffic noise and sometimes causes disputes between drivers.
