The working principle is that the information such as license plate number is stored in the radio frequency tag, which can automatically identify and monitor the vehicle without stopping. It is an extension of passive radio frequency identification (RFID) based on the Internet of Things in the field of intelligent transportation. In the research and development of RFID, ZTE Zhilian has nearly ten years of experience in technical research and product development, and has accumulated a large number of technical knowledge and talent teams, specializing in the research and development, manufacturing, production and sales of RFID products, and providing integrated solutions.
When the bus equipped with the automobile electronic logo is 70 meters away from the stop line of the traffic lights, the sensing equipment arranged at the intersection will detect the "electronic identification card" stuck above the front windshield of the bus. Once the bus is detected, the device will send a priority command to the traffic lights, and the status of the red light or green light will be adjusted immediately. If the direction is green light, the bus will enter the intersection at the end of the green light, and the green light will be automatically extended by 1-8 seconds, so as to ensure that the bus can pass the intersection smoothly without stopping. If the direction is red light, shorten the red light time immediately and start the green light 8 seconds in advance to ensure that the bus entering the intersection passes through the intersection with the shortest waiting time.
Automotive electronic signs have a wide range of applications, not just letting vehicles pass first. Automobile electronic signs have fundamentally changed the traditional road traffic management mode and truly realized the digitalization and intelligence of traffic management. The promotion of automobile electronic signs will promote the construction of comprehensive transportation, intelligent transportation, green transportation and safe transportation, provide intelligent and humanized transportation services for the public, and meet the needs of intelligent transportation management in China.
