Intelligent traffic signal lamp with dimming monitoring function and control method of intelligent traffic signal lamp

Abstract

The invention discloses an intelligent traffic signal lamp with dimming monitoring function and a control method of the intelligent traffic signal lamp. The intelligent traffic signal lamp comprises ahollow supporting rod, of which one end is fixed on the ground, and the other end is provided with a double-sided display. A single-chip microcomputer is arranged in the intelligent traffic signal lamp, and an information acquisition device, the double-sided display, a power supply device and a communication device are electrically connected with the single-chip microcomputer. Displays are arranged on the front face and the back face of the double-sided display. The information acquisition device comprises a light sensor connected with the single-chip microcomputer; an infrared receiver is arranged on the supporting rod, infrared supporting rods are arranged on the two sides of the supporting rod, and infrared emitters matched with the infrared receiver are connected to the infrared supporting rods. The intelligent traffic signal lamp provided by the invention has the functions of dimming monitoring, double-side displaying, real-time brightness adjustment, and employing infrared raysfor monitoring.

Description

technical field [0001] The invention relates to the field of signal control, in particular to a traffic signal lamp, in particular to an intelligent traffic signal lamp with dimming monitoring function and a control method thereof. Background technique [0002] Traffic lights are an important part of traffic command and the basic language of road traffic. At the earliest time, there were only two colors of red and green. Later, after improvement, a yellow light was added. The red light means stop, the yellow light means preparation, and the green light means pass. The reason why these three colors are used is that, on the one hand, they are the three primary colors, on the basis of which other colors are adjusted. On the other hand, the use of these three colors as traffic signals is also related to people's visual structure and psychological response. [0003] The human retina contains rods and three types of cone photoreceptor cells. Rod cells are particularly sensitive t...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the indicating surface of the traffic signal light at the crossing adopts a single-sided setting, and is generally set on one side at the same time, which will cause the vehicle to be easily blocked by the vehicle in front when driving to the crossing, causing a blind spot in the field of vision, and the state of the signal light cannot be seen. Affect driving safety

[0005] More importantly, when the ambient light changes, it is impossible to adjust the signal light brightness according to the ambient light. On the one hand, the real-time adjustment of the signal light brightness is convenient for drivers to observe the traffic status, and it also improves the environmental protection performance of traffic signal lights, prevents light pollution and improves environmental protection. Energy saving; unable to better monitor the traffic status of pedestrians; the power supply method is not ideal; there is no emergency power supply to supply power to the signal lights, once the power is cut off, the signal lights will stop working, which greatly affects the traffic operation status
