Abstract

The utility model relates to a car lamp automatic monitoring device, which relates to the field of radio electronic technique. The utility model is composed of a monitor, a judging circuit, a display and alarm device, etc. No matter when the car lamp is opened or closed, a driver can fully monitor all the car lamps and detect any path or any defective car lamp in time to immediately display and alarm when a switch is opened before a car is started or in the process of running. The device can be arranged or embedded on a suitable position in a cab, and can also be combined with a rearview to form an integral device. One car lamp is used as a basic monitoring unit for expanding to monitor the car lamps of an arbitrary number. The utility model can be widely used in various motor vehicles and various ships.

Description

A kind of car light automated watch-keeping facility

A kind of car light automated watch-keeping facility relates to the radio electronics technical field.

As everyone knows, the state of the illuminating lamp of motor vehicle, signal lamp (being referred to as " car light ") directly influences the driving safety of vehicle, according to statistics, because the accident that the car light fault causes accounts for the 15%-20% of traffic hazard sum, for example, brake lights failure easily causes rear-end collision; The steering indicating light fault can make follow-up or the front vehicles driver can't judge trend and car accident takes place; The headlamp fault makes pilot's line of vision not clear and cause a serious accident; Or the like, therefore press for a kind of device of monitoring car light.Cause that the car light cause faults roughly has the light tungsten filament to blow, the vibration fracture, several situations such as bulb and lamp socket loose contact, these faults are said from circuit and all be can be considered open circuit.At present, some car light detecting devices are arranged, as the brake lamp detecting device, steering indicating light detecting device or the like in order to detect the car light situation, avoids relevant accident to take place, and has played certain effect, has received good effect.But these detector functions are more single, in a certain particular moment, can only implement to detect to car top car light, the difficulty face that receives detects prevention effect formerly, if desire is implemented complete detection, so the puzzlement that unavoidable again pick-up unit too much can't be accepted by the finite space of vehicle and driver is all the time can not promotion and application.

The utility model is intended to provide a kind of car light automated watch-keeping facility, have can be simultaneously to the function of all car light comprehensive monitoring in the vehicle, and as long as open electric switch, no matter vehicle remains static still in the process of moving, also no matter car light is in opening, still be in closed condition, all can monitor automatically, and in time point out the position of trouble light, so that in time repair, avoid serious consequence.

By circuit theory as can be known, circuit is open circuit in a single day, and current in loop will change, and therefore as long as the current in loop change-detection is come out, just can obtain the information of the car light state of correspondence through judging circuit.The utility model is according to the saturation conduction characteristic of the on state characteristic and the transistor of crystal diode, utilize semiconductor module DBM2205-SBC to constitute monitor, be connected in series to vehicle light circuit, by whether there being the open circuit phenomenon in the monitoring circuit, seize the break-make information of car light, this information is transported to by the logic distinguishing circuit of forming with door, Sheffer stroke gate, oscillator etc. by information register, just can be obtained the status information of corresponding car light.Again the information of fault car light is transported to and shown and warning circuit that luminous demonstration of difference and buzzer warning, clock generator are then implemented control to each parts.The position that makes things convenient for the driver to see in the pilothouse can be installed or be embedded in to this device, also can constitute integrated combination with interior mirror.This device can extend to the monitoring to any a plurality of car lights by the elementary cell of the single car light of monitoring.

This device is as long as connect circuit, and the driver can be before going out car and starting, when opening electric switch, or in the process of moving, though car light be out or close, can both carry out comprehensive monitoring automatically to all car lights on the car, in time detect any one the road or the car light of any fault, and show at once and report to the police.Complete function, simple in structure, stable performance, easy for installation, can be widely used on the various motor vehicles and various boats and ships of car types such as comprising motorcycle, tractor.

What Fig. 1 provided is circuit block diagram of the present utility model

What Fig. 2 provided is circuit theory diagrams description of drawings of the present utility model: 1, monitor 2, information register 3, clock generator

4, logic discrimination device 5, demonstration and alarm

In conjunction with the accompanying drawings, provide embodiment of the present utility model.

This device is by monitor (1), information register (2), clock generator (3), logic discrimination device (4) and demonstration and alarm (5) are formed, monitor (1), information register (2), logic discrimination device (4), demonstration and alarm (5) are electrically connected successively, in vain the input end of the monitor (1) that constitutes in order to the semiconductor module DBM2205-SBC of monitoring car light on off operating mode is concatenated in the vehicle light circuit, output terminal is connected in series with the input end of information register (2),, input in the information register (2) as car light break-make information by the output voltage of monitor (1) through output terminal.The output terminal of clock generator (3) is electrically connected with the control end of monitor (1), information register (2), logic discrimination device (4), demonstration and alarm (5) respectively.

Information register (2), logic discrimination device (4) are made of the exclusion RPi (i＞=1) of semiconductor module YM78,50K or 100K, and clock generator (3) is made of semiconductor module OSC-YMO5 and resistance capacitance; Display is made of light emitting diode and transistor and resistance etc., and alarm is made of semiconductor module YMH12, resistance and transistor, and display and alarm constitute demonstration and alarm (5).

The position that the indoor driver of convenience of vehicle drive in time sees various shows signal can be installed or be embedded in to display alarm (5), also can combine with the rearview mirror in the pilothouse, constitutes incorporate demonstration and alarm.

This device can be an elementary cell by car light of monitoring, extends to the automatic comprehensive monitoring of any a plurality of car lights.

Claims

1, a kind of car light automated watch-keeping facility, relate to the radio electronics technical field, by information register (2), clock generator (3), logic distinguishing circuit (4) and demonstration and alarm (5) are formed, it is characterized in that: the input end by the monitor (1) that constitutes in order to the semiconductor module DBM2205-SBC that monitors the car light on off operating mode is concatenated in the vehicle light circuit, output terminal is connected in series with the input end of information register (2), information register (2), logic discrimination device (4), show and the control end of alarm (5) is electrically connected, the output terminal of clock generator (3) respectively with monitor (1), information register (2), the control end of logic discrimination device (4) and demonstration and alarm (5) is electrically connected.
