Embodiment Construction

[0030] The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0031] Such as figure 1 As shown, the traffic signal system includes a traffic signal unit control module 1. The traffic signal unit control module 1 is connected to an LED traffic signal light control card 2 and a receiving module 4 through a circuit. The receiving module 4 will receive QR from the regional traffic information management and dispatch center The matrix two-dimensional code traffic information is sent to the traffic signal unit control module 1. The control module 1 (industrial computer) generates the current red, green, and yellow signal lamp cycles according to the priority, and also sends the QR two-dimensional code information to the LED control card through the serial port. The LED control card drives red, green and yellow traffic lights to display M*M QR code traffic information. In this way, the traffic information and command instructio...

Abstract

The invention discloses an LED optical communication system arranged between a traffic light with an information issue function and a mobile vehicle body. The LED optical communication system comprises a regional traffic information managing and dispatching center, a traffic signal light system, a mobile vehicle-mounted system and a duty traffic policeman temporary information managing and traffic information reporting system. The LED optical communication system has the advantages that by the adoption of the transmission networking mode that traffic information in the form of QR two-dimensional codes is displayed by the LED traffic light and an LED car light, the network structure is simple; the LED traffic light and the LED car light can conduct wireless optical communication with a vehicle-mounted mobile body while conducting information indication, and by means of the feature that the QR two-dimensional codes are large in information storage capacity, the traffic information is issued to relieve road congestion, improve active safety precaution of vehicles and reduce traffic accidents.

Description

Technical field [0001] The invention belongs to the technical field of LED optical communication, and relates to an LED optical communication system between an information issuing function traffic light and a mobile vehicle body. Background technique [0002] As the scale of cities continues to increase, the city’s transportation network is becoming more and more complex. The road design of international developed countries adopts the design of separating people, vehicles and non-motorized vehicles, but our country still adopts a mixed traffic design, even in the era of motorized transportation. Today, the mixed traffic design is still adopted, and all problems are handed over to the traffic signal intersection, so traffic jams will inevitably occur. At present, traffic congestion on urban roads is a world-class problem. The reason is that mathematical models of road traffic are difficult to establish and control decisions are difficult to make. LED traffic lights, LED lights, a...
