Background technology
Traffic lights are that the urban road intersection Different Traffic Flows is let pass and the important Warning Mark of forbidding, light color correctly whether light the security of the lives and property that is related to each burst traffic flow, therefore need traffic administration person to know closely whether it is in normal condition, in case it is unusual, bad as green conflict, red light, then must detect the signal lamp state, be notified to the teleseme processor then and do that corresponding degradation is handled and traffic police command centre is given in long-range repayment by accurate and reliable pick-up unit.The fault of signal lamp is mainly divided 3 kinds: open a way, open circuit, make contact or short, the signal lamp failure state that relates to is exactly " this bright not working, should not be bright bright ".Reason owing to engineering construction, teleseme drives each lamp group and gets back to rack zero line and after connecing usually, each street lamp group is by forceful electric power unit different in the teleseme such as controllable silicon, relay output live wire, so testing circuit is placed in the signal rack usually, then may be a lot of and draw farly in the signal lamp loop, will occur opening a way, open circuit, make contact and the situation of short.Detection method mainly contains two kinds, and a kind of is that the serial connection current transformer judges that by detecting current threshold break-make is with unusual on signal lamp forceful electric power unit output loop; Another kind is the voltage that detects on the forceful electric power unit output line, judges whether unusually by voltage threshold.Preceding kind detects most widely used general, can judge open circuit and open circuit fault, but often there is mouse to come in and go out under some local signal cabinet, mouse likes stinging electric wire, the result causes short and makes contact, also have the improper and environmental change of engineering construction personnel wiring to cause making contact that electric wire chaps and cause, that all can cause serious signal lamp failure to influence traffic safety.
Domestic signal lamp failure testing circuit major part is unreliable, insecure reason mainly is that the immature and single testing circuit light current circuit of testing circuit may be subjected to the periphery electromagnetic environment interference, cause the processor erroneous judgement disconnected, the processing controls simultaneously of simultaneously many teleseme processors, communication, fault supervision and calculation task, operation and supervision effectively not being separated, itself also is the disconnected root of erroneous judgement.So many businessmans mask fault detection capability often selling consumer products.Can be referring to the paper " China's road traffic signal controller authentication system research " in " 2008 the 3rd Chinese international traffic safety forum collection of thesis " of up-to-date publication, paper author Mr. Lu Haifeng is the staff of traffic safety product inspection center of the Ministry of Public Security, he often detects domestic teleseme because of work relationship, and he mentions domestic many teleseme manufacturer non-fault monitoring function in the literary composition.So the non-fault that is in domestic quite a few teleseme detects " three do not have " state of can't the remote monitoring non-fault reporting to the police, perhaps the unreliable unrest of fault detect is reported to the police and is downgraded to the yellow light-off work of dodging, bring greatly trouble for the maintenance of traffic police functional department, make domestic traffic safety have serious hidden danger.Key reason is that teleseme works in the outfield, and working environment is comparatively abominable, and non-stop run throughout the year, and so general failure detector circuit just is difficult to realize reliably fault detect.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, design a kind of can simple and reliable ground detection signal lamp open circuit, open circuit and make contact fault, send to the teleseme processor then and judge whether that green conflict and red light are bad, carry out the degradation processing and send to remote monitoring terminal by communication network, with the quality and the cross junction security of raising road traffic signal machine, and the road traffic signal lamp failure of reduction maintenance workload detects servicing unit.
The present invention is achieved by the following technical solutions:
A kind of device that is used for road traffic signal lamp failure supervision detection includes fault detection unit and coupled teleseme processor, and described fault detection unit is respectively current detection module and voltage detection module; The Transistor-Transistor Logic level signal of the Transistor-Transistor Logic level signal of voltage detection module output and current detection module output is by linking to each other with the detection IO mouth of flush bonding processor with door; The flush bonding processor signal output part is connected with described teleseme processor signal input end.
A kind of device that is used for road traffic signal lamp failure supervision detection, described flush bonding processor signal output part is connected with described teleseme processor signal input end by serial converter spare.
A kind of device that is used for road traffic signal lamp failure supervision detection, described flush bonding processor is 8 or 16 MCU.
A kind of detection method that is used for road traffic signal lamp failure supervision pick-up unit, flush bonding processor detects the Transistor-Transistor Logic level signal behind every road signal lamp voltage detection unit and the current detecting unit logical and, make comparisons with the normal light color of this road signal lamp of the actual output of teleseme processor, if all are normal, then continue the detection of next signal lamp unit, road, otherwise in the unit interval, the number of stoppages that the beginning circle statistics detects behind software filtering, as long as reach the more than half unusual of sum, then be judged to be fault.
Beneficial effect with respect to prior art is, one, the fault detect of every road signal lamp no longer merely relies on voltage detecting or current detecting, but by the result of voltage detecting and current detecting logical and, no matter current detecting unit and voltage detection unit, have only the two-way detecting unit simultaneously correctly just for normal, otherwise know that promptly this road signal lamp breaks down, can improve the reliability of fault detect like this; Its two, the every road of flush bonding processor individual processing signal lamp failure situation independently can reduce the burden of teleseme processor, realizes effectively separating of operation power and authority to supervise, can improve operational reliability greatly; Its three, judge that by probabilistic method abnormal conditions possess higher reliability and fault detect self-repair function.
