Abstract
The utility model relates to the electronic alarm technology, particularly a fault alarm for a vehicle indicating lamp, comprising a voltage detected circuit, a voltage comparator, a trigger, a simulation language circuit, etc. The fault alarm for a vehicle indicating lamp can automatically monitor the fault of the vehicle indicating lamp. When the fault of indicating lamp out of the vehicle body happens, the acoustic-optic alarm is dispatched to remind the driver of paying attention and excluding the fault on time to ensure the traveling safety. The fault alarm for a vehicle indicating lamp has the advantages of high sensitivity, exact operation, low energy consumption, low cost, convenient wire connection, etc.
Description
The utility model relates to electronic alarm technique, particularly the vehicle lamp accident warning device.
At present, the various power actuated vehicles that travel both at home and abroad, such as car, passenger vehicle, lorry and special vehicle etc., preceding viewing-wide lights (side light) and taillight when turning in the process of moving, brake and night running, all indicate by the exterior indicator lamp of car body, the traffic policeman commands in view of the above, and pedestrian and other vehicle are taken care in view of the above.Because gauge panel in the operator's compartment and indicator lamp and the exterior indicator lamp of car body are not gone the same way, the operation of indoorly can only reflect whether chaufeur turns to, brake and preceding viewing-wide lights (side light) and taillight being lighted, therefore, when the exterior indicator lamp of car body is damaged, during malfunctioning or bad earth, chaufeur is not known, and conventional operation has caused the generation of traffic accident violating the regulations.This is a difficult problem that perplexs automobile driver for a long time.
The purpose of this utility model provides a kind of highly sensitive, and action is accurately consumed energy and lacked, and cost is low, the vehicle lamp fault alarm apparatus of easy-to-connect.This device can automatically be monitored vehicle lamp, in case during faults such as indicator lamp occur to damage, malfunctioning or bad earth, send sound and light alarm, prevents the generation of the traffic accident that causes because of the indicator lamp fault.
The utility model is achieved through the following technical solutions: be contained in vehicle lamp fault alarm on the operator's compartment inner control platform and be by the voltage detecting circuit that enters the voltage comparator input end side by side and reference voltage circuit and voltage comparator, binary pair, analogous language circuit, power amplification circuit, loud speaker and be connected in sequence.
Below in conjunction with accompanying drawing performance of the present utility model is described.
Accompanying drawing 1 is the utility model most preferred embodiment block scheme.As can be seen from the figure, voltage detecting circuit is made up of detection resistance, voltage clamping circuit, voltage follower.Detect resistance string and be connected in the vehicle lamp circuit, its parameter is 0.1-0.5,4-8W.Voltage clamping circuit is joined by 3-10 end and detection resistance, and the other end is formed with the stabilivolt of voltage follower and resistance grounded respectively.Detect ohmically detection voltage and behind voltage clamping, enter voltage follower, send into voltage comparator again.Reference voltage circuit is made up of through reference voltage circuit and voltage clamping circuit that two series resistance connected to chassis two resistance provide power supply.When the exterior indicator lamp of car body just often, green LED is lighted; When faults such as the exterior indicator lamp of car body is damaged, malfunctioning or bad earth, carry out the voltage of voltage ratio after through voltage comparator and send into the binary pair of forming by gate circuit, the red light emitting diodes of reporting to the police between binary pair and the loud speaker is lighted, and sent language or music alarm through analogous language circuit, power amplifier promotion loud speaker.
Accompanying drawing 2 is an interconnecting wiring diagram of the present utility model.As seen from the figure, (2) and (3), (4) and (5), (6) and (7), (8) and (9) are connected on the two ends that resistance is detected on each road respectively, and are serially connected in respectively in indicator lamp master cock and the circuit that indicator lamp is connected.(1) be supply terminals, (2) (4) (6) (8) are respectively the input adapter of each switch, and (3) (5) (7) (9) are respectively and respectively organize indicator lamp input end joint, and (10) are the bonding terminals.
Claims (6)
1, a kind of power actuated vehicle indicator lamp fault alarm apparatus is connected in sequence by the voltage detecting circuit that enters the voltage comparator input end side by side and reference voltage circuit and voltage comparator, binary pair, analogous language circuit, power amplification circuit, loud speaker.
2,, it is characterized in that testing circuit is made up of detection resistance, voltage clamping circuit, voltage follower according to the vehicle lamp fault alarm apparatus of claim 1.
3,, it is characterized in that reference voltage circuit is made up of through reference voltage circuit, voltage clamping circuit that two series resistance connected to chassis two resistance provide power supply according to the vehicle lamp fault alarm apparatus of claim 1.
4, according to the vehicle lamp fault alarm apparatus of claim 1, it is characterized in that binary pair is made up of gate circuit.
5,, it is characterized in that being connected between binary pair and the loud speaker red light emitting diodes of warning according to the vehicle lamp fault alarm apparatus of claim 1.
6, according to the vehicle lamp fault alarm apparatus of claim 1, it is characterized in that terminals (2) and (3), (4) and (5), (6) and (7), (8) and (9) are connected on the two ends that resistance is detected on each road respectively, and be serially connected in respectively among indicator lamp master cock and the circuit that indicator lamp is connected.
