Abstract
The utility model discloses a detection warning device of an automobile tail light. The detection warning device is characterized by comprising a single chip microcomputer, an illumination intensity meter, a warning light and a spare tail light, wherein the illumination intensity meter is connected with an input end port of the single chip microcomputer, the warning light and a relay are connected with an output end port of the single chip microcomputer, and the relay is connected with the spare tail light. When the automobile tail light is broken, the detection warning device can actively show warning to drivers and sending warning signals to back automobiles by starting the spare light through the single chip microcomputer, guarantee reaction time of the drivers of the back automobiles so that traffic accidents are reduced. The detection warning device of the automobile tail light has the advantages of being simple in structure, low in cost, stable in property and convenient to popularize in a large range.
Description
Technical field
The utility model relates to a kind of alarm device, relates in particular to a kind of SCM Based automobile tail light and detects detecting device.
Background technology
Rear-end collision is one of normal traffic accident that occurs on highway, and its major cause is that the front truck chaufeur runs into that unforeseen circumstances is taken measures or when normally changing, rear car chaufeur could not in time take suitable countermeasure to cause bumping with front truck according to the action of front truck.And front tail-light is the main source that front vehicle receives front vehicles information, if the taillight brightness of front truck is inadequate or damage, so when front truck slows down, stops or turns to, rear car chaufeur can not be understood the intention of front vehicles in time, the time of making a response will be grown even and can not make correct reaction, rear-end collision easily occurs hurt innocent persons.Research is found, reduces the generation that time of driver's reaction will reduce the rear-end collision accident.The detecting device of this automobile tail light in the time of can or damaging in the automobile tail light luminance shortage, gives a warning to chaufeur, and reminding driver is in time changed taillight, thereby can reduce the generation that safety hazard is avoided accident.Therefore, the utility model is extremely important to safety traffic.
Summary of the invention
The purpose of this utility model is, a kind of initiatively detection alarm device of the automobile tail light of early warning mechanism that adopts is provided.
In order to realize above-mentioned task, the utility model adopts following technical solution to be achieved:
A kind of detection alarm device of automobile tail light, it is characterized in that, comprise micro controller system, Illumination intensity meter, Warning light, relay and standby taillight, wherein, the Illumination intensity meter is connected with the input port of micro controller system, Warning light is connected with the micro controller system output port with relay, and relay is connected with standby taillight.
The utility model also has following technical characterictic:
Described micro controller system adopts Freescale S12 model micro controller system.
The detection alarm device of automobile tail light of the present utility model, can be initiatively when automobile tail light damage to this car chaufeur warn and by micro controller system enable standby taillight backward car send early warning signal, guarantee the reaction time of rear car chaufeur, thereby effectively reduce the generation of traffic accident.The utility model is simple in structure, and cost is low, and stable performance is convenient to popularize on a large scale and promote.
Description of drawings
Fig. 1 is the block diagram of the detection alarm device of these practical automobile tail light.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The specific embodiment
At first need to prove; following specific embodiment only is used for those skilled in the art to understanding of the present utility model; the utility model is not limited to this embodiment, and all equivalents or adding technique features of doing on the application's technical scheme basis all should belong to protection domain of the present utility model.
As shown in Figure 1, the present embodiment provides a kind of detection alarm device of automobile tail light, comprises micro controller system, the light intensity measuring instrument that is connected with micro controller system respectively, Warning light, relay and standby taillight.Wherein, the Illumination intensity meter is connected with the input port of micro controller system, and Warning light is connected with the micro controller system output port with relay, and micro controller system switches on and off by the standby taillight of Control.
In the present embodiment, micro controller system adopts Freescale S12 model micro controller system.Be used for receiving the signal of Illumination intensity meter and signal being processed the output alarm control signal.
Light intensity measuring instrument is installed in the housing of automobile tail light, for detection of the brightness situation of automobile tail light.
Warning light can adopt LED lamp or infraluminescence pipe, is installed on the gauge panel of operator's compartment, is used for informing the damaged condition with the reminding driver automobile tail light.
Standby taillight is installed in the housing of automobile tail light, and the lighting circuit of taillight of being connected with automobile connects by relay, is used for when automobile tail light damage, and car sends early warning backward.
Adopt the detection alarm device of automobile tail light of the present utility model, when car brakeing or when turning to, when automobile tail lamp circuit was connected, device was connected circuit and is started working, at first, the Illumination intensity meter detects the brightness of taillight, when the brightness of taillight lower than the taillight original intensity 2/3 or when not working, the Illumination intensity meter will send signal to micro controller system, micro controller system is received signal, Warning light is lighted in control, and lights the car early warning backward of standby taillight.When automobile is got back to the straight-line travelling state, when tail lamp circuit cut off, standby taillight extinguished, and Warning light continues to the chaufeur early warning.
