Form the closed loop feedback, the accuracy of trouble discovery obtains improving, but also can judge the failure cause on which signal lamp of which direction of crossing according to both results relatively.
Description
Technical field
The utility model relates to transport information control technology field, is specifically related to a kind of traffic signal light fault pick-up unit.
Background technology
Existing market is broadly divided into following two kinds of modes to the detection mode of signal lamp failure:
1, signal lamp failure detects the voltage, the current detecting that only rely on traffic controller to self output signal circuit for lamp.
2, signal lamp self is to the voltage of power circuit or current detecting.
Signal lamp work is exported by the signal of traffic light controller and controls, and for whole system, the signal of traffic controller exports and belongs to instruction sender, and signal lamp is then the recipient of instruction.Due to above-mentioned two kinds of detection modes to signal lamp failure, just traffic controller to own operating condition or signal lamp to the detection of self duty, and not simultaneously to the detection of signal sender and recipient's state, the effect performed after not sending instruction is in other words fed back, so above-mentioned two kinds of detection modes do not have to accomplish close-loop feedback and make the accuracy rate of warning greatly reduce with detection is comprehensive in fault detect.
Summary of the invention
The utility model object is to provide a kind of traffic signal light fault pick-up unit, to solve the deficiencies in the prior art.
The utility model is by the following technical solutions:
A kind of traffic signal light fault pick-up unit, comprise signal lamp voltage check part, wireless data signal emission element, traffic controller voltage/current detection parts, wireless data signal receiving-member, signal lamp voltage check part input end is connected with signal lamp, for detection signal lamp current operating state, output terminal is connected with wireless data signal emission element, for the signal lamp current operating state of detection is sent to wireless data signal receiving-member, traffic controller voltage/current detection parts are arranged between signal lamp and traffic controller connecting line, output signal for detection signal lamp controller, traffic controller voltage/current detection part input is connected with wireless data signal receiving-member, for Received signal strength lamp current operating state information, and traffic controller output signal and signal lamp current operating state are compared, result is consistent, judge that signal lamp is in normal operating conditions, result is inconsistent, judge that signal lamp is in abnormal operating state.
Further, described wireless data signal emission element is integrated in signal lamp voltage check part; Described wireless data signal receiving-member is integrated in traffic controller voltage/current detection parts.
Further, described signal lamp voltage check part comprises voltage detecting circuit, governor circuit, wireless data signal transmitter module, and the input end of described voltage detecting circuit is connected with signal lamp, and output terminal is connected with governor circuit; Governor circuit output terminal is connected with wireless data signal transmitter module.
