Abstract
The utility model discloses a backup lamp failure alarming device. The backup lamp failure alarming device comprises a central processing unit, a current sensor, an alarming module and a micro switch linked with a backup lamp switch, wherein the current sensor is connected in series with a backup lamp circuit; the central processing unit is electrically connected with the data output end of the current sensor, the alarming module and the micro switch respectively. The backup lamp failure alarming device can detect whether a backup lamp works normally during backup of an automobile and an alarm is sent to a driver through the alarming module if the backup lamp works abnormally to remind the drive that the backup lamp works abnormally to prevent safety accidents.
Description
Technical field
The utility model relates to a kind of warning device, relates in particular to a kind of backing-up lamp failure alarm device.
Background technology
New Type of Reversing Lamp is that the active safety that requires of national legislation must piece installing, while being intended to move backward, remind rear pedestrian and send a car and notice that this car is in reverse travel, laws and regulations requirement must assemble (containing a 1) above backing-up lamp, and now a lot of vehicles are all only assembled a backing-up lamp, if backing-up lamp circuit breaker or bulb lost efficacy, backing-up lamp will not work, to rear pedestrian or vehicle does not have warning function, and chaufeur is moveed backward in the situation that not knowing that backing-up lamp lost efficacy, be easy to cause safety misadventure.
China Patent Publication No. CN202573962, open day on December 5th, 2012, the name of utility model is called a kind of new car tail lamp system, this application case discloses a kind of new car tail lamp system, it comprises the tail-light being comprised of lamp box, light-emitting lamp and lampshade, described light-emitting lamp is provided with four, is respectively the lamp that travels of backing-up lamp, steering indicating light, braking/parking lamp and prompting normal vehicle operation; Lampshade correspondence is divided into four regions, be respectively the transparent region corresponding with backing-up lamp, with the corresponding yellow area of steering indicating light, with the corresponding red area of braking/parking lamp and green area or the blue region corresponding with the lamp that travels; Described tail-light system also comprises controller, turn signal swich, back-up lamp switch, is arranged on the braking sensor on brake pedal and is arranged on the throttle sensor in Das Gaspedal, and turn signal swich, back-up lamp switch, braking sensor and throttle sensor are controlled steering indicating light, backing-up lamp, braking/parking lamp and the lamp that travels by controller respectively.Its weak point is, this new car tail lamp system breaks down while not working and can not remind chaufeur to know at backing-up lamp.
Summary of the invention
If the purpose of this utility model is to overcome backing-up lamp circuit breaker or backing-up lamp fault, backing-up lamp can not lighted when reversing automobile, to rear pedestrian or vehicle does not have warning function, and chaufeur is moveed backward in the situation that not knowing that backing-up lamp lost efficacy, be easy to cause the technical matters of safety misadventure, a kind of backing-up lamp failure alarm device is provided, whether it can detect backing-up lamp and work when reversing automobile, if backing-up lamp is normal operation not, by alarm module, to chaufeur, send warning, remind the not normal operation of chaufeur backing-up lamp, prevent the generation of safety misadventure.
In order to address the above problem, the utility model is achieved by the following technical solutions:
A kind of backing-up lamp failure alarm device of the present utility model, comprise central processing unit, current sensor, alarm module and the micro-switch linking with back-up lamp switch, described current sensor is serially connected with in backing-up lamp circuit, and described central processing unit is electrically connected to data output end, alarm module and the micro-switch of current sensor respectively.
In the technical program, during chaufeur reversing, hang reverse gear, back-up lamp switch is closed, and closed with the micro-switch of back-up lamp switch interlock, central processing unit receives the energizing signal that micro-switch sends.Central processing unit detects the electric current in backing-up lamp circuit by current sensor, if the current value detecting is not in default normal range, central processing unit judges backing-up lamp circuit breaker or backing-up lamp fault, central processing unit controls alarm module sends warning, remind the not normal operation of chaufeur backing-up lamp, prevent the generation of safety misadventure.
As preferably, described alarm module comprises the indicator lamp being arranged on Auto Instrument desk, and described indicator lamp is electrically connected to central processing unit.During reversing automobile, if backing-up lamp normal operation, indicator lamp does not work; If backing-up lamp is normal operation not, indicator lamp is lighted.
As preferably, described alarm module comprises the voice output circuit being arranged on Auto Instrument desk, and described voice output circuit is electrically connected to central processing unit.During reversing automobile, if backing-up lamp normal operation, voice output circuit is not worked; If backing-up lamp is normal operation not, central processing unit controls voice output circuit sends audio alert.
As preferably, described central processing unit is micro controller system.
Whether the beneficial effects of the utility model are: when reversing automobile, can detect backing-up lamp and work, if backing-up lamp is normal operation not, by alarm module, to chaufeur, send warning, remind the not normal operation of chaufeur backing-up lamp, prevent the generation of safety misadventure.
Accompanying drawing explanation
Fig. 1 is that a kind of circuit theory of the present utility model connects block diagram.
In figure: 1, central processing unit, 2, current sensor, 3, alarm module, 4, micro-switch, 5, indicator lamp, 6, voice output circuit, 7, back-up lamp switch, 8, backing-up lamp, 9, power supply.
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: a kind of backing-up lamp failure alarm device of the present embodiment, as shown in Figure 1, comprise central processing unit 1, current sensor 2, alarm module 3 and the micro-switch 4 linking with back-up lamp switch 7, alarm module 3 comprises indicator lamp 5 and voice output circuit 6, current sensor 2 is serially connected with in backing-up lamp circuit, central processing unit 1 is electrically connected to data output end, micro-switch 4, indicator lamp 5 and the voice output circuit 6 of current sensor 2 respectively, and central processing unit 1 is micro controller system.The backing-up lamp circuit of automobile is the loop being connected into by back-up lamp switch 7, backing-up lamp 8 and power supply 9.
During chaufeur reversing, hang reverse gear, back-up lamp switch 7 closures, with micro-switch 4 closures of back-up lamp switch 7 interlocks, central processing unit 1 receives the energizing signal that micro-switch 4 sends, and backing-up lamp failure alarm device is started working.The electric current that central processing unit 1 detects in backing-up lamp circuit by current sensor 2.
If the current value detecting is not in default normal range, central processing unit 1 judges backing-up lamp circuit breaker or backing-up lamp 8 faults, central processing unit 1 is controlled indicator lamp 5 and is lighted, control voice output circuit 6 and send audio alert, remind not normal operation of chaufeur backing-up lamp 8, prevent the generation of safety misadventure; If the current value detecting is in default normal range, central processing unit 1 judgement backing-up lamp 8 works, and indicator lamp 5 does not work, and voice output circuit 6 is not worked.
