Fig. 3 is the schematic circuit diagram of the utility model embodiment.
Fig. 4 is that the utility model uses the connection diagram when the brake lamp circuit.
See also accompanying drawing 1.A kind of car bulb self check of the utility model and fault alarm, it is indoor to be located at vehicle drive, comprises casing 1 and is located at control circuit in the casing.The panel of casing is provided with display lamp 2, news Chinese percussion instrument 3, and the side of casing or rear portion are provided with control circuit output pig-tail wire 5.Light-emitting diode V1, V2 in the display lamp 2 corresponding control circuits; Buzzer phone FA in the news Chinese percussion instrument 3 corresponding control circuits; K switch in the source switch 4 corresponding control circuits.
Ask for an interview Fig. 2, described control circuit comprises: electromagnetic switching circuit 6, oscillating circuit 7 and sound light alarming circuit 8.The input end of electromagnetic switching circuit is connected in series with a certain street lamp loop of automobile, and the mouth of electromagnetic switching circuit is connected with the input end of oscillating circuit, and the mouth of oscillating circuit is connected with the input end of sound light alarming circuit.
Ask for an interview Fig. 3, described electromagnetic conversion warning circuit 6 is made of inducer L, magneto sensor VG, plays detection effect in circuit.Inducer L is connected circuit input end, the field signal of magneto sensor VG (model for example is 3121) receiving inductance device L.
Described oscillating circuit is made up of aerotron V7, V8, resistance R 1, R2, R7, R8, capacitor C 3, C4 etc., plays control gap warning effect in circuit.The base stage of aerotron V7 is connected with mouth 3 pin of magneto sensor VG, and its collecting electrode is connected with the base stage of aerotron V8.
Described sound light alarming circuit is made of aerotron V6, buzzer phone FA, light-emitting diode V1, V2 (light-emitting diode can be one, and present embodiment is provided with two) and resistance R 5, R6, capacitor C 2.Be connected with the emitter of aerotron V8 after light-emitting diode V1, the V2 parallel connection.Buzzer phone FA is connected with the collecting electrode of aerotron V6, and the base stage of aerotron V6 is connected by the base stage of biasing resistor with aerotron V7, and V6 plays the amplification driving action in circuit.
Also comprise a power circuit, this circuit is by aerotron V4, V5, and diode V3 and zener diode D form, for the The whole control circuit provides a stable power.
The utility model warner for light trouble of vehicle is a kind ofly to be used for monitoring a certain street lamp light of automobile mode of operation, and can be in advance when in a single day car light burns out in vehicle ' with the electronic product of prompting.Its principle of work is:
When circuit working just often, have electric current to flow through inducer L and produce magnetic field, record magnetic field by magneto sensor UG, magneto sensor the 3rd pin conducting over the ground ends aerotron V7, aerotron V8 conducting, light-emitting diode VI, V2 have electric current to flow through and are luminous.Otherwise, when the drg bulb bad, open circuit, when no current did not produce magnetic field through inducer L, magneto sensor UG the 3rd pin was opened a way over the ground, makes aerotron V7, V8 enter oscillatory regime, cause light-emitting diode V1, V2 flicker, while aerotron V8 collecting electrode place high level, aerotron V6 gets electric, drives buzzer phone FA and produces alarm sound.
Ask for an interview Fig. 4, this is that the utility model uses the connection diagram when the brake lamp circuit.The redness of by the method shown in the figure output of the utility model warner for light trouble of vehicle being drawn during use, green, yellow three leads connect automobile brake K switch, brake lamp N1, N2, ground connection respectively.Be in normal condition when braking light, during the chaufeur footbrake, the red indicating light 2 of warner for light trouble of vehicle top is bright with step-length with tailstock brake lamp.In case the braking bulb of automobile burns out, when the chaufeur footbrake, the red indicating light of warner for light trouble of vehicle top will send flicker and report to the police, and news Chinese percussion instrument 3 sends chimes of doom.
The utility model warner for light trouble of vehicle has self check warning sensitivity height, and good reliability does not have The advantage that loss detects, and small volume, the installation wiring is simple, easy to use.
