Abstract
The utility model provides a can monitor car light monitor that car exterior lamp normally worked or broke down, main detection circuitry is the middle coil that is equipped with the magnetic conductor core, and the next door sets up a magnetic sensitive components and parts sampling circuit, and this components and parts are close to the terminal surface of coil, and the output signal termination luminescent circuit or sound production circuit or reputation circuit of magnetic sensitive components and parts. The automobile lamp has the advantages of small resistance, low energy consumption, prolonged service life of the automobile lamp, interference resistance and high reliability.
Description
The utility model relates to a kind of car bulb monitoring device, especially relates to a kind of accessible monitor of car bulb.
At present, China produces and does not have vapour embarkation lamp function for monitoring in the automobile overwhelming majority of usefulness.When automobile when the lamp et out of order does not work outside certain, the chaufeur in the car can't find in time that this gives traffic safety, the rule that observe traffic laws are brought certain difficulty.
The purpose of this utility model provides a kind of car bulb monitor, and it can inform automobile driver to the mode of operation of various automobile external light accurately, intuitively, thus guarantee driving safety.
The technical solution of the utility model provides with following form:
A kind of car bulb monitor, it comprises: shell and the printed board that has testing circuit; Wherein testing circuit is the middle coil that is provided with the magnetizer core, the next door is provided with a Magneto Elements sampling circuit, and this Magneto Elements is near a certain end face of described coil, the output signal end sending and receiving optical circuit of Magneto Elements or phonation circuit or sounding optical circuit; Described testing circuit is connected in the car light circuit.
In the such scheme, described testing circuit is arranged between car light and the lighting switch.
The principle of work of monitor of the present utility model is: behind switch closure, embarkation lamp is bright, and electric current flows through coil, hub of a spool produces magnetic field, this magnetic field will make Magneto Elements action, and the Magneto Elements mouth is active potential, and its output signal is not worked demonstration such as light or sound or cue circuit.When certain car light breaks down (open circuit), coil current reduces, and the magnetic field that coil produced is not enough to drive Magneto Elements, and the Magneto Elements mouth is high potential, makes luminous display circuit work.
Car bulb monitor of the present utility model has following advantage:
1, whole circuit contact pointless, nothing blocking-up do not have other resistance except that interface contact resistance and line resistance, thereby, do not influence original lamplight brightness substantially.2, energy-conservation; Under circuit was operated at full capacity situation, working current was no more than 100 milliamperes.3, signal transducer double as inductance, the electric current of surging when turning on light has certain inhibit function, thereby lamp life is prolonged to some extent.4, power consumption is little, temperature rise is low, the life-span is long, high reliability features because the components and parts selected for use all have, thus an index such as the reliability of complete machine, service life, disturbance rejection all energy is satisfactory.
Below in conjunction with drawings and Examples, further specify the technical solution of the utility model.
Fig. 1 is the schematic circuit diagram of car bulb monitor;
Fig. 2 is the schematic circuit diagram that this device is applied in big fermentation hired car.
Car bulb monitor of the present utility model comprises: shell and the printed board that has testing circuit, wherein testing circuit as shown in Figure 1, power transmission line 1 by a fixed length is wrapped on the magnetizer 2, the coil 3 that the magnetizer core is arranged in the middle of constituting, the next door is provided with Magneto Elements 4 sampling circuits, Magneto Elements 4 is near the lower surface 5 of coil 3, output signal end 6 sending and receiving optical circuits or phonation circuit or the sounding and the optical circuit of Magneto Elements 4; Testing circuit is connected in the car light circuit.
With reference to Fig. 2, this device is applied to the schematic circuit diagram on the Tianjin Dafa utility van, the left and right steering indicating light of automobile, stoplight stop lamp and preceding side-marker lamp, registration mark light are identical with back side-marker lamp's circuit, light switch is last, car light is following, and this Device Testing circuit is arranged between light switch K and the car light D, and its output signal end 6 is through diode D
1Insert luminous and phonation circuit.The circuit of automobile dipped headlight and country beam is identical, by aerotron 3DG, resistance R
5, R
6After the commutation, this Device Testing circuit is arranged between light switch K and the car light D, and its output signal end 6 inserts luminous and phonation circuit through diode D1.
Luminous and phonation circuit is by time base circuit integrated package 7, warning indicator lamp 8, buzzer phone 9, R
1, R
2, R
3And C
1, C
2Form.
Magneto Elements 4 can be selected breakerless Hall element for use, also can select the electromagnetic relay of contact for use.
Time base circuit integrated package 7 can adopt NE555.
When arbitrary bus lamp D was out of order, mouth 6 was high potential, was high potential through diode D1 at NE555 contact R place, this moment buzzer phone 9 sound, warning indicator lamp 8 is bright.
