Abstract
The invention relates to an independent fault detection and processing circuit for an intelligent traffic signal control machine. The independent fault detection and processing circuit comprises a microprocessor, wherein the signal input end of the microprocessor is connected with a detection circuit used for carrying out voltage and current detection on red, green and yellow lamps, the signal output end of the microprocessor is respectively connected with the control ends of a first switch and a second switch, the first switch is connected with a lamp group live wire, and the second switch is connected with a yellow lamp live wire. The fault detection of the independent fault detection and processing circuit aiming at each signal lamp does not singly depend on the voltage detection or the current detection, the two detection modes are simultaneously adopted for detection, the signal lamps are normal only two detection units are simultaneously correct, or the signal lamps have fault, and the fault detection reliability is improved. In addition, when one lamp group generates the serious mistakes that the red lamp is normally turned off, the red lamp and the green lamp are turned on at the same time, the red and green conflict is generated, and the like, the independent fault detection and processing circuit does not relay on the instructions of a signal machine, a power supply of the signal lamps is switched off through switching off the first switch, then, the yellow lamp is singly driven to do the yellow lamp flickering operation, and the load of a signal machine processor is reduced.
Description
?
Technical field
The present invention relates to the traffic lights field, especially a kind of independent failure of intelligent traffic signal controller detects and treatment circuit.
Background technology
The fault of signal lamp mainly is divided into three kinds: open a way, open circuit, make contact or short, the malfunction that directly causes teleseme is exactly that the bright order of lamp is all upset.The non-fault that is in domestic quite a few teleseme detects, can't remote monitoring, non-fault " three do not have " state of reporting to the police; Perhaps because fault detect is unreliable, disorderly warning; Can only be downgraded to the yellow light-off work of dodging, perhaps carry out the degradation processing and send to remote monitoring terminal through communication network.Yet because teleseme works in the outfield, working environment is comparatively abominable, and non-stop run throughout the year, and therefore general failure detector circuit just is difficult to realize reliably fault detect.
?
Summary of the invention
The object of the present invention is to provide a kind of realization that fault is carried out in real time, detected reliably, and the independent failure of intelligent traffic signal controller independent, that automatically fault is handled detect and treatment circuit.
For realizing above-mentioned purpose; The present invention has adopted following technical scheme: a kind of independent failure of intelligent traffic signal controller detects and treatment circuit; Comprise microprocessor, its signal input part links to each other with the testing circuit that is used for red, green, yellow lamp is carried out voltage, current detecting, and its signal output part links to each other with the control end of first and second switch respectively; First switch links to each other with lamp group live wire, and second switch links to each other with the amber light live wire.
Can know by technique scheme; The present invention is directed to the fault detect of every road signal lamp; No longer merely rely on voltage detecting or current detecting, but take two kinds of detection modes to detect simultaneously, have only the two-way detecting unit simultaneously correctly just for normal; Otherwise know that promptly this road signal lamp breaks down, and has improved the reliability of fault detect.In addition, when occur a certain lamp group red light often go out, red green during with gross errors such as bright, green conflicts, no longer rely on the instruction of teleseme; And through cutting off first switch; Cut-off signal lamp power supply drives amber light then alone and carries out yellow snap action, has reduced the burden of teleseme processor.
Description of drawings
Fig. 1 is a circuit block diagram of the present invention.
Embodiment
A kind of independent failure of intelligent traffic signal controller detects and treatment circuit; Comprise microprocessor 1; Its signal input part links to each other with the testing circuit that is used for red, green, yellow lamp is carried out voltage, current detecting, and its signal output part links to each other with the control end of first and second switch respectively, and first switch links to each other with lamp group live wire; Second switch links to each other with the amber light live wire, and described lamp group live wire is the live wire group that includes red, green, yellow lights line.The signal output part of said microprocessor 1 links to each other with the signal input part of the central processor CPU of teleseme, and is as shown in Figure 1, and the present invention can also carry out direct communication with teleseme.
As shown in Figure 1; Described testing circuit is made up of first, second and third voltage and current detection circuit 2,3,4; The input end of first, second and third voltage and current detection circuit 2,3,4 links to each other with red light, green light, amber light respectively, and the output terminal of first, second and third voltage and current detection circuit 2,3,4 links to each other with the signal input part of microprocessor 1.Fault detect needs the duty of picked up signal lamp, and general working voltage detects and two kinds of means of current detecting.Conventional, current detecting is generally more accurate than voltage detecting, such as; When signal lamp opens circuit; Current detecting can detect the circuit no current, and voltage detecting then can't detect circuit for opening circuit, but voltage detecting also has than current detecting and has superiority when following situation; Such as line electrical leakage, erroneous detection will appear in current detecting.Best fault detect mode is exactly to use two kinds of detection modes simultaneously, so the present invention takes voltage, two kinds of detection modes of electric current to detect simultaneously, has only the two-way detecting unit simultaneously correctly just for normal, otherwise knows that promptly this road signal lamp breaks down.
As shown in Figure 1, described first switch adopts relay 5, and the control end of relay 5 links to each other with the signal output part of microprocessor 1, and the input end of relay 5, output terminal connect lamp group live wire respectively.Described second switch adopts controllable silicon 6, and the control end of controllable silicon 6 links to each other with the signal output part of microprocessor 1, the input termination lamp group live wire of controllable silicon 6, the output termination amber light live wire of controllable silicon 6.Microprocessor 1 is judged after detecting each signal lamp state; When occur a certain lamp group red light often go out, red green during with gross errors such as bright, green conflicts, need not to rely on to send instructions under the teleseme, microprocessor 1 can be through breaking off relay 5; Break off the forceful electric power power supply of three signal lamps; Drive controllable silicon 6 then alone, drive amber light and carry out yellow snap action, reduced the burden of the central processor CPU of teleseme.
