Abstract

The invention relates to the technical field of traffic signal lamps, in particular to a city smog traffic signal lamp which comprises a traffic signal lamp body, a visibility detection system and a control system. The city smog traffic signal lamp can monitor the influence of smog weather on traffic in real time, and is adjusted to be enhanced in light intensity in smog days in order to improve warning information, thereby strengthening the guidance information for drivers on the road, so that the function of the traffic signal lamp can be exercised normally, thereby maintaining the stabilityand safety of the urban traffic. A photosensitive sensor is used to receive the attenuation degree of the optical signals transmitted from different angles, comprehensively determine the degree of smog around the traffic signal lamp, improve the detection accuracy of the visibility detection system, and improve the safety and stability of the traffic signal lamp.

Description

technical field [0001] The invention relates to the technical field of traffic signal lamps, in particular to an urban haze traffic signal lamp. Background technique [0002] Smog, as the name suggests, is fog and haze. But the difference between fog and haze is very big. The aerosol system composed of dust, sulfuric acid, nitric acid and other particles in the air causes visual impairment called haze. Haze is haze (haze). Fog is an aerosol system composed of a large number of tiny water droplets or ice crystals suspended in the air near the surface. It mostly occurs in autumn and winter (this is also one of the reasons for the large-scale smog in January 2013), and is the product of condensation (or sublimation) of water vapor in the air near the surface. The existence of fog will reduce the transparency of the air and deteriorate the visibility. If the horizontal visibility of the target is reduced to within 1000 meters, the weather phenomenon of water vapor condensati...
