Description
Technical field
The utility model relates to the automobile component testing circuit, relates to or rather automobile flasher relay testing circuit.
Background technology
Electronic flashing device for turning indicators of car is the flashing feature that changes be used to indicating vehicle traveling direction.Der Blink und Abblendschalter is driven by flasher relay, so flasher relay is most important concerning electronic flashing device for turning indicators of car.At present, the flasher circuit on the automobile comprises Der Blink und Abblendschalter, winker switch, flasher relay and two steering indicating light groups.Two steering indicating lights are connected in parallel and form the steering indicating light group.Described Der Blink und Abblendschalter, winker switch, flasher relay and steering indicating light group are connected on the two ends of automotive battery.During work, closed winker switch, flasher relay is just started working, and outputs to steering indicating light, and steering indicating light begins flicker.
The automobile flasher relay all will pass through before dispatching from the factory and detect, and present automobile flasher relay testing circuit complex structure, and the quality of automobile flasher relay can only artificially be judged the easy phenomenon that erroneous judgement occurs according to parameter.
The utility model content
The technical problems to be solved in the utility model is, provide a kind of simple in structure, when detecting inferior-quality flasher relay can and the automobile flasher relay testing circuit of alarm.
Technical solution of the present utility model is, a kind of automobile flasher relay testing circuit with following structure is provided, and comprises photoelectric coupled circuit, micro controller system, power circuit, digital display circuit and warning circuit; The signal input part of described photoelectric coupled circuit is connected with the mouth of the automobile flasher relay that is detected; The signal output part of described photoelectric coupled circuit is connected with micro controller system; Described digital display circuit and warning circuit all are connected with described micro controller system; Described power circuit provides power supply for micro controller system and photoelectric coupled circuit.
After adopting above structure, automobile flasher relay testing circuit of the present utility model compared with prior art, has the following advantages:
During automobile flasher relay output signal, photoelectric coupled circuit will receive signal and can be to the micro controller system signal transmission, photoelectric coupled circuit is the equal of the frequency of flasher relay to the frequency of micro controller system signal transmission, the frequency of namely flash light flicker, digital display circuit is used for the display frequency value, can see intuitively the output frequency value of flasher relay, see that the flasher relay output frequency value just can judge whether flasher relay works, and whether Der Blink und Abblendschalter meets national standard; If the signal that micro controller system receives and the value of setting in it are inconsistent, micro controller system will drive warning circuit, and to report to the police to point out detected flasher relay be off-grade, during such as the output frequency mal of flasher relay or flasher relay when damaging, by this kind mode, be not easy the phenomenon that occurs judging by accident.
