Abstract

The utility model discloses an automatic pedestrian crossing signal lamp comprising a red signal lamp body and a green signal lamp body which are arranged on a lamp pole, power supply input ends of the red and the green signal lamp bodies are respectively and electrically connected with a power supply output end through a normally open contact and a normally closed contact of a relay; and a drive coil of the relay is electrically connected with an output drive circuit of a camera head or the output drive circuit of an infrared sensor. The automatic pedestrian crossing signal lamp has the advantages that the safety and the road utilization efficiency of crossings with the pedestrian passage flow which has the characteristics of time periods are improved, such as the road crossings of schools, kindergartens, plant entrances and the like, when in time periods of going to or from school or going to or from work, the crossings are in the peak periods of pedestrian flow, a pedestrian signal is collected by the camera head or the infrared sensor, and a power supply of the red signal lamp is switched on for forbidding the passage of vehicles; when in other time periods, the pedestrians are fewer, the camera head or the infrared sensor can not collect the pedestrian signal at most of the time, and then the green signal lamp is switched on for allowing the passage of the vehicles.

Description

Automatic pedestrian crosswalk signal lamp

Technical field

The utility model relates to traffic lights, especially relates to automatic pedestrian crosswalk signal lamp.

Background technology

Traffic lights are widely used in the urban and suburban roads traffic intersection, have played good adjustment, standard pedestrian and vehicle pass-through effect.The traffic lights that are used for place, forks such as school, kindergarten, factory doorway at present take to set up the flashes yellow warning lamp more, in order to the prompting vehicle driver's safety that watches for pedestrians of travelling.Though yellow warning lamp plays certain warning function, more can cause the visual alarm effect for the red traffic lights of driver.Because above-mentioned traffic fork walk flow has the time period characteristic, therefore set up regularly exchange to show that the red and green signals lamp will reduce the road service efficiency again, influence the cruising of motor vehicle.

The utility model content

The utility model purpose is to provide a kind of automatic pedestrian crosswalk signal lamp that improves fork place's traffic safety and road service efficiency.

For achieving the above object, the utility model can be taked following technical proposals:

Automatic pedestrian crosswalk signal lamp described in the utility model, it comprises that red, the described power input red, the green signal light body of green signal light body that are arranged on the lamp stand are electrically connected with power output end by relay normally open contact, normally closed contact respectively; The drive coil of described relay is electrically connected with the output driving circuit of the output driving circuit of camera or infrared ray sensor.

The utility model advantage just is to improve security and the road service efficiency that the walk flow has time period characteristic fork in the road.Such as fork roads such as school, kindergarten, factory doorways, in upper and lower or commuter time section, the fork is in rush hour, gathers pedestrian signal by described camera or infrared ray sensor and drives the actuating of relay, the closed signal red light power disable vehicle pass-through of connecting of normally opened contact; And in section At All Other Times, pedestrian's rareness, most time camera or infrared ray sensor collection are less than pedestrian signal, and relay is not worked, and normally opened contact disconnects, the closed green signal light clearance vehicle of connecting of normally closed contact.Therefore not only improved the service efficiency of fork road, the setting of signal red light has simultaneously also improved the pedestrian's of place, fork security greatly.
