Description

Technical Field

[0001] The present invention relates to the technical field of traffic roads, and particularly to a monitoring device for traffic lights and a monitoring method thereof. Background Technique

[0002] Traffic lights are devices used to control vehicle and pedestrian traffic, usually installed at road intersections, crosswalks, etc. Their main purpose is to ensure the safe and orderly progress of road traffic. The working principle of traffic lights is: through a computer or mechanical control system, according to traffic flow and time arrangement, the switching of three colors of lights, red, green, and yellow, is realized. When the red light is on, it means no driving is allowed; when the green light is on, vehicles are allowed to pass; and when the yellow light is on, it prompts the driver to pay attention to the possible red light ahead. After a vehicle passes through the intersection, the next cycle starts to ensure that all vehicles comply with traffic rules.

[0003] When traffic lights are in use, monitoring devices are needed to monitor them to improve the monitoring efficiency and accuracy of traffic lights, thereby optimizing traffic flow, reducing traffic congestion, and enhancing road traffic capacity. When existing monitoring devices are in use, they are usually directly installed on the monitoring pole, but the monitoring position and height of the monitoring probe cannot be adjusted, and the monitoring range is small, resulting in the inability to adjust the monitoring position according to road conditions. When there are obstacles in the monitoring screen, the height of the monitoring device cannot be adjusted in time to avoid the obstacles, which affects the monitoring effect of traffic lights, and the monitoring probe is not easy to clean. After long-term use, a large amount of dust will adhere to the probe, and the dust will affect the monitoring clarity. Summary of the Invention
