Abstract
The utility model belongs to the technical filed of electronics and machinery, which relates to a monitoring device for the state of an automobile lamp. The utility model comprises an automobile lamp, a power supply, a photoelectric triode, a trumpet, a self-flash diode, a resistor, a capacitor, an operation amplifier circuit, a diode, a voltage stabilization diode, a speech chip, etc., wherein, the resistor, the capacitor, the operation amplifier circuit, the diode, the voltage stabilization diode, the speech chip, etc. are arranged in a main control box. The utility model adopts sensitivity technology and circuit technology, and besides, the utility model can detect wire-breaking faults of lamp bulbs of all the automobile lamps and make an alarm lamp flash and generate speech prompt to send out fault alarm signals so as to reduce situations of violation of traffic regulations or generation of accidents. The utility model provides a monitoring device for the faults of the automobile lamp which is simple and convenient in use for drivers.
Description
The utility model belongs to electronics and field of mechanical technique, relates to a kind of automobile lamp fault monitoring device.
Most automobiles all do not have the car light fault monitoring device, car steering person is in driving condition in driving procedure, because car steering person can't observe the user mode of the outer front car light of car body, back car light and side lights, if when front car light, after car light and measuring car lamp damage is arranged, when the driver correctly provides the car light signal, because the damage of car light makes the driver can't judge the intact situation of car light, therefore easily cause the car light state in the practical operation difference, cause to violate the traffic regulations or traffic hazard easily takes place.
The purpose of this utility model is the inconvenience that solution does not have the automobile of car light fault monitoring system to bring for car steering person, easily causes the problem that violates the traffic regulations or traffic hazard easily takes place, and a kind of automobile lamp state monitoring apparatus is provided.Because it is to be signal source (also can directly detect car light) with the photoelectric sensor,, install very convenient so can not change original technology of automobile and performance.This device can also pass through other sensor or measured object, realizes the detection to physical quantity, break-make warning, burglar alarm, remote control and the automatic control etc. on electricity (line) road.
The utility model can detect bulb disconnection faults such as taillight, license plate lamp, side-marker lamp and headlamp, and makes red light emitting diodes glimmer, make voice system to produce voice suggestion, sends failure alarm signal to the driver.
Detailed content of the present utility model is as shown in Figure 1: it comprises accumulator E, K switch, car light L1, L2, phototriode VT, loudspeaker BL, flicker LED, settles resistance R 1, R2, R3, R4, operational amplifier IC, diode VD, triode BG, capacitor C 1 and C2, R5, R6, speech chip IC2, voltage stabilizing diode DW in primary control box.The end of R1, R2 is connected with the positive pole of phototriode, the other end of R2 is connected with the in-phase input end of transport and placing device IC, the end of R3, R4 is connected with the inverting input of IC1, and the leg VDD of the other end of R1, R3, worry ripple capacitor C 1 positive pole, voltage stabilizing diode DW negative pole, IC1 is connected with lighting switch K, the negative pole of the leg Vss of the other end of R3 and IC1, DW positive pole, worry ripple capacitor C 1 is connected with the negative terminal of automobile power source, constitutes voltage comparator circuit.The output terminal of IC1 is connected with the positive pole of isolating diode, the end of negative pole and R5 is connected with other isolating diode VD that respectively organizes detecting device, the other end of R5 is connected with the b utmost point of triode BG, the e utmost point of BG is connected with the positive pole of LED, negative terminal is connected with ground, and the c utmost point of BG, the end of R6 are connected with the positive pole of capacitor C 2, and negative pole is connected with the input end of speech chip IC2, the output termination loudspeaker of speech chip IC2, the other end of R6 connects accumulator E.
When lighting switch K closure, when car light L1, L2 non-fault, car light is bright, and the A point current potential of comparer IC1 is lower than B point reference potential, and IC1 exports electronegative potential, not conducting of triode BG, and glimmer certainly LED and speech chip IC2 do not work, and do not have alerting signal; When car light L1, L2 have a fault or two fault to be arranged, the A point current potential of comparer IC1 is higher than the B point, IC1 exports noble potential, triode BG conducting, make warning system red light emitting diodes LED flicker, loudspeaker BL produces the sound equipment prompting, thereby reaches the purpose (among Fig. 1 other respectively organize car light fault detect principle identical) of sound, light warning car light fault.
Fig. 2 is the primary control box synoptic diagram of automobile lamp fault monitor.Primary control box pastes and is placed in the back in-support carriage of automobile, alarming horn can paste on the back seat platform that is placed in the car, alarm lamp should be placed on the position that the driver easily watches, and phototriode pastes and is placed on (window of phototriode is laid facing to car light) in the corresponding car light lampshade.
The utility model adopts sensitive technology and circuit engineering, realization is to the detection and the warning of the disconnection fault of car light bulb, make the driver can in car, judge the intact situation of car light, the utility model has solved the inconvenient problem with use that prior art brings for car steering person, thereby reduced the situation generation that violates the traffic regulations or traffic hazard takes place, for car steering person provides a kind of use automobile lamp state monitoring apparatus simply and easily.
