Description
Technical field
The present invention relates to technical field of intelligent traffic, more particularly to a kind of intelligent detecting method and its intelligent controller that transit equipment fault can be carried out with real-time detection.
Background technology
Traffic control signal machine is the visual plant controlling intersection traffic signal, is the important component part of traffic signal control system, and various traffic control schemes finally all to be realized by traffic control signal machine.At present in most of urban traffic control of China, it has been commonly used the control to intersection traffic signal for the traffic control signal machine.Because traffic control signal machine is arranged on urban road crossing, work under bad environment, easily it is subject to external interference, signal lamp failure, traffic signal conflict, signal lamp failure etc. can be produced, if these faults can not being diagnosed in time and being processed, vehicle accident may be induced, cause traffic jam, cause serious consequence.Some traffic signal controlling machines do not possess malfunction monitoring function now, or malfunction monitoring single function, such as only possess green collision detection function and the current/voltage function of signal controlling machine itself, even only possesses a kind of wherein single function, so needing to carry out real-time detection to the running status of traffic control signal machine, and carry out fault diagnosis, take appropriate measures when occurring abnormal.
Existing major part traffic control signal machine, in design production process, compares the realization of the control function focusing on semaphore, and the fault diagnosis technology of semaphore is considered less it is impossible to meet the demand of actual working environment well.Some have the typically no independent fault detection module of semaphore of fault detection capability, and be integrated in signal controlling machine, once therefore signal controller operational failure, fault detection capability also lost efficacy therewith, do not reach the effect of fault detection and diagnosis, and detect that fault type is single, typically only have the detection of green collision failure.
Now the fault detect of crossroad traffic signal lamp is broadly divided into no detection pattern and have detection pattern.Due to the reason such as structure of the detecting device is complicated, expensive, some traffic signal controls do not have the function that the fault for signal lighties is detected.When signal lighties break down, semaphore does not take any measure because not having detection function, continues the control signal lamp that does as usual.This kind of method makes the break down vehicle in direction of signal lighties be thrown into confusion, and causes motor vehicles not know this stop-for-waiting or normally travel, ultimately results in the congestion of crossing, or even vehicle accident.Semaphore does not have the reasons such as signal lamp failure detection, signal lighties working condition can only rely on the feedback of user or the artificial investigation of supervisor, detection, confirm and then keep in repair, ultimately result in traffic monitoring personnel and can not obtain the information such as Intersections working condition, deterioration extent in time, timely signal lamp failure maintenance can not be carried out, make the time to be solved such as fault very long, control impact very big at crossing.
Prior art is also proposed the semaphore with signal lamp failure detection function.This kind of signal function real-time monitoring signal lighties whether fault, when detect red green with catastrophe failures such as bright or green conflicts when, semaphore carries out degradation control to signal lighties while fault information reporting is solved to higher level's request.By shutoff signal lamp power supply, independent driving amber light carries out yellow sudden strain of a muscle and controls, and makes the signal lighties of whole crossing all enter yellow sudden strain of a muscle pattern.But, semaphore controls to yellow sudden strain of a muscle of degradation of transit equipment fault, whole crossing can be made to be absorbed in non-mandrel roller, although semaphore has detection and reporting functions to signal lamp failure, can remind supervisor that failure problems are timely processed, but the installation site of signal lighties is away from odjective causes such as traffic surveillance and control centers, fault is reported to solve from fault, centre at least needs 1～2 hour, if run into that maintainer task is busy, the special circumstances such as rush-hour, bad weather circumstances when, the time will more lengthen.Intelligent traffic signal machine product producer is numerous simultaneously, but product quality is very different, particularly the detection to signal lamp failure, directly affects the traffic safety of people.The semaphore of some producers does not possess detection function, causes cannot solve fault in time.
