Integrated adaptive intelligent traffic warning sign

Abstract

The invention discloses an integrated adaptive intelligent traffic warning sign comprising an intelligent controller, a weather collection unit, a visibility detection unit, an event detection unit and an LED screen display unit; the weather collection unit, the visibility detection unit, the event detection unit and the LED screen display unit are integrated. The weather collection unit comprises a weather information collection controller and a sensor. The visibility detection unit comprises a visibility viewer. The event detection unit comprises a people and vehicle information collection module. The intelligent controller receives data from the weather collection unit, the visibility detection unit and the event detection unit, analyzes the collected data through a special software algorithm, independently adjusts indexes such as information release contents, forms and brightness without dependence on communication and control of a background center, and outputs corresponding output signals to the LED screen display unit. The integrated adaptive intelligent traffic warning sign allows warning for traffic safety on roads, especially expressways, and thus, fatal traffic accidents on the roads and expressways are effectively prevented or decreased.

Description

technical field [0001] The invention discloses an integrated adaptive intelligent traffic warning sign and relates to the technical field of traffic safety facilities. Background technique [0002] In recent years, my country's highways, especially expressway construction, have developed very rapidly. Since my country's first highway, especially the expressway, was built in 1988, by the end of 2010, the mileage of my country's highways, especially the expressway, had reached 73,000 km. According to the "National Highway, Especially the Expressway Network Planning", my country is going all out to speed up the construction of national highways, especially the main framework of the expressway network. By 2020, the national highways, especially the expressway network, will be basically completed. By then, the total mileage of China's highways, especially expressways, will reach 100,000 km. The new road network consists of 7 capital radial lines, 9 north-south longitudinal line...

Problems solved by technology

[0006] At present, although there are some traffic warning signs and weather monitoring stations on highways, especially expressways, the correlation between the two is not high

Most of the existing traffic warning signs on highways, especially on highways, can only display fixed warning slogans and have no actual relationship with the actual road conditions, thus failing to achieve practical technical effects; and the information of a small number of existing weather monitoring stations must be controlled Only the center can publish on the variable information board. First, the information cannot be timely, and the relevant information has to go through multiple links such as front-end collection, transmission, and background processing; second, the entire system is expensive and cannot be popularized, and cannot meet the needs of highways, especially highways. The need for traffic safety management
