Abstract
The utility model belongs to lamp light monitoring equipment for a motor vehicle, which comprises a housing, a protective cover and an indication panel. The utility model has the technical key point that both ends of a vehicle lamp are connected with a voltage compared type detection device composed of an integrated circuit, a resistor, a light emitting diode and a detection line, wherein the integrated circuit is a comparison amplifier. The voltage compared type detection device is controlled by the voltage variation of both of the two ends of the vehicle lamp, and then the operating condition of the vehicle lamp is monitored by the display of an indicating lamp.
Description
The utility model belongs to the automobile lamplight monitoring equipment, particularly a kind of voltage comparative type detecting device that uses integrated circuit, resistance, light-emitting diode, detection line to form.Be applicable to the brake that monitors all kinds of power actuated vehicles and install, turn to, the operating mode of signal lamps such as distance light, dipped beam.
Whether the signal lamp on the existing self-propelled vehicle is normal, and chaufeur can't accurately be judged in operator's compartment.Only after energized, the employed signal lamp of direct viewing could be found fault.Existing automotive lamp optical monitor can only could be found employed signal lamp failure from monitoring device when using light, but can not the failure judgement position.When not using light, the signal lamp et out of order can show on monitoring device.And the obsolete time of motor vehicle signal lamp is much larger than period of service.Therefore, find that timely and accurately the fault that motor vehicle signal lamp taken place is also very necessary when not using.For example: automobile is not use stop, tail and number plate light in running at high speed, and et out of order is undiscovered as if this lamp, and when running into the emergency situation brake, send a car and can not find in time that its stop, tail and number plate light is bright in the back, and car accident just easily takes place.
The purpose of this utility model is for overcoming a kind of performance of above-mentioned deficiency design-calculated vehicle signal monitoring device accurately and reliably, the driver just can judge various signal lamp operating modes and fault happening part at any time intuitively, exactly in operator's compartment, so that in time trouble-shooting is guaranteed traffic safety.
The utility model mainly is made up of installation bent plate 1, shell 2, protective cover 3, circuit unit 4, indication panel 5, mounting screw 6, detection line 7.
It mainly is that monitoring device is fixed on the automobile instrument panel that bent plate 1 is installed.Shell 2, protective cover 3 main protective circuit assemblies.
Circuit unit 4 is made up of analog IC, resistance, light-emitting diode, wiring board.
Indicate the title of light-emitting diode institute respective signal lamp above the indication panel 5.
Task of the present invention is finished like this: it be at the two ends of car light 12 one in parallel form the voltage comparative type detecting device by integrated circuit 15, resistance 16,19, light-emitting diode 8, detection line 7 and resistance 18.Wherein: integrated circuit 15 is comparison amplifiers.At the two ends of switch 14 resistance 18 in parallel, the resistance value of resistance 18 should be greater than the resistance value of car light 12.Two comparison signal input ends of divider resistance 16,19 in parallel, integrated circuit 15 are connected on respectively between resistance 18 and the car light 12 on the detection line 7 and on the connecting wire between resistance 16 and the resistance 19 at the two ends of power supply 9.The mouth of integrated circuit 15 is through the negative pole of light-emitting diode 8 power connections 9.
When not using light, car light 12 is normal, and to the resistance very little (less than 10 ohm) between the grounding jumper 11, the voltage comparative type detecting device is output as low level to check point 13 through car light 12, and light-emitting diode 8 does not work proves that car light 12 is good; If car light 12 fracture of wires or wire break, check point 13 are to the resistance infinity between the line 11 of getting a lift (the millions of ohms of your writing), the voltage comparative type detecting device is output as high level, and light-emitting diode 8 is bright, proves that check point 13 opens circuit between grounding jumper 11.
When using light, power lead 10 is good, switch 14 closed conductings, and check point 13 improves level, and detecting device is output as high level, and light-emitting diode 8 is bright, shows car light 12 states.If check point 13 opens circuit or bonding between the power supply 9, check point 13 is low levels, and light-emitting diode 8 does not work, and proves that check point 13 opens circuit or bonding between the power supply 9.So just can judge the trouble location when whether various signal lamps normally reach mal easily according to the bright of each light-emitting diode on the monitoring device or the two states that do not work.
The utility model and traditional automotive lamp optical monitor relatively have the following advantages:
1, energized does not use light to know just whether each car light that is monitored is normal.The i.e. moment of et out of order shinny immediately warning of cooresponding indicator lamp on the monitoring device when car light does not use.
2, can accurately judge the car light trouble location by monitoring device.
3, cost is low, the life-span is long.Monitor that each car light cost is about 2 yuan, is not less than 10 years service life.
