Abstract

The invention puts forward a traffic signal advance guide display device comprising a control circuit and a display screen, wherein the control circuit comprises a signal collection unit, a lamp group configuration module, a one-chip microcomputer and a driving circuit; an input end of the signal collection unit is connected with a traffic signal light, an output end of the signal collection unit is connected with an input end of the one-chip microcomputer, the lap group configuration module is connected with the one-chip microcomputer, an output end of the one-chip microcomputer is connected with the riving circuit, an output end of the driving circuit is connected with the display screen, the display screen is used for displaying a next traffic direction and count-down time according to driving signals. The traffic signal advance guide display device can help traffic participants get familiar with next traffic direction signified by the traffic signal light beforehand, crossroad traffic efficiency can be improved, and the traffic signal advance guide display device can be widely applied to the traffic field.

Description

technical field [0001] The invention relates to a traffic signal preview display device, which belongs to the field of traffic signal display. Background technique [0002] In recent years, traffic lights (that is, traffic signal display devices) have been generally installed on ground roads. Traffic lights are an important part of the traffic command system and the basic language for expressing road traffic rules. They play a very important role in the establishment of road traffic order. effect. [0003] At present, traffic lights are composed of red light (expressing prohibition of passage), green light (expressing permission of passage), and yellow light (expressing warning). Red light, green light or yellow light are all formed by a single light source. Such light source is controlled by a circuit system. Most intersections adopt a multi-phase release mode. The release method and order are affected by the traffic flow, flow direction and surrounding traffic environment...
