Urban traffic information indicator system with complementation between solar energy and alternating current

Abstract

The invention discloses an urban traffic information indicator system with complementation between solar energy and alternating current. The urban traffic information indicator system with the complementation between the solar energy and the alternating current comprises a power supply system, a controller, a sampling unit, a memory unit, a display unit, an electrical level switching circuit, a clock calendar chip and an upper computer, wherein the power supply system supplies power for the controller and the controller controls the power supply system, the sampling unit collects road traffic information and transmits the road traffic information to the controller, the memory unit is connected with the controller, the display unit displays current traffic information in real time, the electrical level switching circuit is connected with the controller and the display unit and converts electrical level of a transistor-transistor logic(TTL) to electrical level of a radio station (RS) 232, the clock calendar chip is connected with the controller, and the upper computer is arranged in a command center and transmits wireless information with the controller through a wireless transmission unit. Changing-over between the alternating current and the solar energy power supply is achieved, the current road condition information is transmitted to an urban traffic command center in real time, various road signs and important word prompt message can be displayed at the same time, the road condition information which is strong in timeliness and is strong in pertinence is provided for drivers, and traffic pressure can be released to a large degree.

Description

technical field [0001] The invention relates to an indication system, in particular to an urban traffic information indication system in which solar energy and mains electricity are complementary. Background technique [0002] At present, many road indicators in the city adopt a fixed method, which has poor timeliness and cannot be flexibly changed according to road conditions, and has a single function, less information to prompt, and a short viewing distance. Although there are also a lot of places where electronic road signs are installed, it is inconvenient to use wired wiring for most of them, and the use of mains power to supply power to a large number of such electronic road signs will consume a lot of urban power. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an urban traffic information indication system in which solar energy and commercial power are complementary to each other in view of the above-men...
