Energy-conserving intelligent all-weather road traffic signpost and control method

Abstract

The invention provides an intelligent all-weather traffic sign and a control method thereof. An energy-saving and intelligent all-weather traffic sign comprises an optical sensing unit, and a brightness control switch of LED lamps, a singlechip and an LED assembled lamp; the optical sensing unit and the brightness control switch of the LED lamps are respectively connected with the corresponding pins of the singlechip, the LED assembled lamp is connected with the brightness control switch of the LED lamps, the optical sensing unit is used for collecting light intensity signals, sending the original light intensity signals to the singlechip regularly, calculating the current light intensity grading compared with the basic value, triggering the brightness control switch of the LED lamps on the different pins to output different modulating voltages, so as to control different brightness and display different sign shapes. The invention has the effects and advantages of (1) effectively avoiding and reducing traffic accidents, (2) having certain intelligence and self-adaptability, (3) having 'all-weather' capability and (4) effectively saving electrical energy.

Description

technical field [0001] The invention relates to an energy-saving intelligent all-weather road traffic sign board and a control method. Background technique [0002] At present, among the domestic road traffic signs, most of the directional signs and guide signs have a blue or green background with white patterns or characters, most of the prohibition signs have a black pattern with a red frame and a white background, and most of the warning signs have a black frame with a yellow background. Black patterns or text standards are made of reflective materials, supports, foundations and fasteners, etc., and are hung on both sides of the road where drivers and pedestrians can easily see them. At night, they need to be illuminated by street lights to facilitate people's identification and guide people. March. The advantage of this type of scheme is that it is easy to make, but the disadvantages are: [0003] (1) It is greatly affected by weather conditions, especially in areas wi...

AI Technical Summary

Problems solved by technology

[0003] (1) It is greatly affected by weather conditions, especially in areas with heavy fog, with low visibility and low recognition;

[0004] (2) When the light intensity is weak, such as cloudy days or nights, it is easy to cause drivers or pedestrians to neglect some traffic signs

[0005] (3) When there is heavy fog or light intensity is weak, in order to effectively guide people to move forward, a large number of street lights are used to provide lighting for roadside traffic signs, which consumes a lot of power

In addition, if the street lamps that provide lighting for traffic signs are damaged or the car is driving in a road area without street lights, it will be difficult for people to observe the traffic signs, which will easily cause traffic accidents and cause loss of life and property.
