Abstract

The utility model discloses a wireless remote-control traffic light, which comprises signal lights powered by the mains supply and a signal light controller, wherein the signal output end of the signal lights controller is electrically connected with a radio signal emitter, and the input end of the driver circuit of the signal light is electrically connected with a radio signal receiver. The utility model has the advantages that the radio signal emitter at the signal output end of the signal lights controller and the radio signal receiver at the input end of the driver circuit of the signal lights are used together to control the wireless transmission of the signals; the power of the signal light controller and the signal lights can be supplied by the lighting mains at the crossings after stepping down, rectification, filtering, and voltage-stabilizing. Therefore, the power cable and the single cable are not required to be laid, bringing about a reduction in the construction cost of discrete traffic light and a shortening of construction period with no need to dig out the road.

Description

The wireless remote control traffic lights

Technical field

The utility model relates to traffic lights, especially relates to the wireless remote control traffic lights.

Background technology

The traffic lights that are used for large-scale traffic intersection at present adopt the discrete traffic lights more, and existing discrete traffic lights need excavated pavement to lay power cable and signal cable, have therefore increased equipment investment, have prolonged the construction time.

The utility model content

The utility model purpose is to provide a kind of wireless remote control traffic lights that do not need to lay signal cable.

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

Wireless remote control traffic lights described in the utility model, it comprises signal lamp, the traffic controller that power supply is provided by utility grid, is electrically connected with wireless signal transmitter at described traffic controller signal output part; Driving circuit input end at described signal lamp is electrically connected with wireless signal receiver.

The utility model advantage is by being arranged on the wireless signal transmitter of described traffic controller signal output part, realize the wireless transmission of control signal with the wireless signal receiver that is arranged on signal lamp driving circuit input end, the power supply of traffic controller and signal lamp can be provided after step-down, rectification, filtering, voltage stabilizing by the power for illumination at traffic intersection place; Therefore do not need to lay power cable and signal cable, saved the construction cost of discrete traffic lights, shortened construction period, and do not needed excavated pavement.
