Abstract
The utility model discloses a burglar alarm of an automobile spare wheel. The burglar alarm of the automobile spare wheel comprises an antitheft host, an alarm body and a wireless receiving and sending module and further comprises an ultrasonic rangefinder installed on a chassis of an automobile. A signal is sent between the wireless receiving and sending module and the antitheft host in a wireless mode and the ultrasonic rangefinder is electrically connected with the wireless receiving and sending module; ultrasonic waves are sent by the ultrasonic rangefinder towards the spare wheel and ultrasonic waves reflected by the spare wheel are received by the ultrasonic rangefinder; the time difference of an ultrasonic wave sending moment and an ultrasonic wave receiving moment is sent to the antitheft host by the wireless receiving and sending module and when the time difference is increased, the alarm body is started by the antitheft host to give an alarm. The antitheft host reads the time difference sent by the wireless receiving and sending module at set intervals and when the current read time difference is larger than the time difference read last time, the alarm body is started by the antitheft host to give the alarm. The burglar alarm of the automobile spare wheel can give the alarm in time, prevent the automobile spare wheel from being stolen and is good in induction stability and small in false alarm.
Description
Technical field
The utility model relates to a kind of car alarm, relates in particular to a kind ofly to respond to good stability, report few anti-theft apparatus for spare by mistake.
Background technology
Existing self-propelled vehicle, especially lorry, no matter be engine petrol or diesel motor, its vehicle body is heavier, when there is stolen event, tire or stolen often.Because general high capacity waggon self is heavier, not only bad dismounting of miscellaneous part on automobile, and also price is generally all lower, does not steal and is worth.And motor tire or spare tyre utilizability are high, value is good, and also easily dismounting, often becomes theft object.Existing automobile does not generally have tire or anti-theft device for spare tire, and spare tyre dismounting will lift car chassis endlessly, more easily stolen, once spare tyre is stolen, can not find in time, can delay thing yet, causes economic loss.
Utility model content
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, provides a kind of and responds to good stability, reports few anti-theft apparatus for spare by mistake.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is: comprise anti theft host, annunciator and radio receiving transmitting module, also comprise the ultrasonic range finder being arranged on car chassis for detection of the distance between ultrasonic range finder itself and spare tyre; Between described radio receiving transmitting module and anti theft host, by wireless mode, transmit signal, ultrasonic range finder is electrically connected to radio receiving transmitting module; Ultrasonic range finder sends super sonic and receives to spare tyre direction is sent out by spare tyre the super sonic reflecting; Time difference when described radio receiving transmitting module is launched super sonic and between while receiving sends to anti theft host, and when the described time difference becomes large, anti theft host starts alarm equipment alarm.
As the further improved technical scheme of the utility model, described anti theft host reads the time difference that radio receiving transmitting module sends at set intervals, before this time difference of reading is greater than, once read time difference time, anti theft host starts alarm equipment alarm.
As the further improved technical scheme of the utility model, described anti theft host reads every the time of 10 seconds to 1 minute the time difference that radio receiving transmitting module sends over.
As the further improved technical scheme of the utility model, described annunciator is combined aural and visual alarm.
As the further improved technical scheme of the utility model, when automobile starting, anti theft host sends the order of withdrawing a garrison, and makes radio receiving transmitting module, anti theft host, annunciator and ultrasonic range finder in out-of-run readiness for action; When automobile flameout, anti theft host sends the order of withdrawing a garrison, and makes radio receiving transmitting module, anti theft host, annunciator and ultrasonic range finder in running order.
Ultrasonic range finder of the present utility model sends super sonic, then receive the excusing from death ripple being reflected by the spare tyre of automobile, and the spare tyre of transmitting the super sonic time difference between super sonic and ultrasonic range finder and automobile with reception distance is between the two corresponding, time difference is large, distance is large, time difference is little, and distance is little; If the time difference becomes large, illustrate that spare tyre is moved, likely stolen, at this moment anti theft host starts alarm equipment alarm.The variation of the spare tyre that the utility model compares to judge ultrasonic range finder and automobile by the distance of twice of front and back distance between the two, rather than the direct distance between the two of the spare tyre by measuring ultrasonic range finder and automobile, then the spare tyre of the ultrasonic range finder of the distance of measurement and setting and automobile distance is between the two compared, because if air temperature variations, time difference also can change, distance will change, and can cause wrong report.In a word, the utility model is measured the distance between ultrasonic range finder itself and the spare tyre of automobile by ultrasonic range finder, by anti theft host, judge the variation of the distance between ultrasonic range finder itself and the spare tyre of automobile, can and alarm, prevent that automobile spare tire is stolen, and induction good stability, wrong report is few.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further.
The specific embodiment
embodiment 1
Referring to Fig. 1, this anti-theft apparatus for spare comprises anti theft host, annunciator and radio receiving transmitting module, also comprises the ultrasonic range finder being arranged on car chassis for detection of the distance between ultrasonic range finder itself and spare tyre; Between described radio receiving transmitting module and anti theft host, by wireless mode, transmit signal, ultrasonic range finder is electrically connected to radio receiving transmitting module; Ultrasonic range finder sends super sonic and receives to spare tyre direction is sent out by spare tyre the super sonic reflecting; Time difference when described radio receiving transmitting module is launched super sonic and between while receiving sends to anti theft host, and when the described time difference becomes large, anti theft host starts alarm equipment alarm.Described anti theft host reads the time difference that radio receiving transmitting module sends at set intervals, and during the time difference of once reading before this time difference of reading is greater than, anti theft host starts alarm equipment alarm.Described a period of time is 10 seconds to 1 minute, can be according to specifically selecting, and such as 10 seconds, 20 seconds 30 seconds etc.Described annunciator is combined aural and visual alarm.When automobile starting, anti theft host sends the order of withdrawing a garrison, and makes radio receiving transmitting module, anti theft host, annunciator and ultrasonic range finder in out-of-run readiness for action; When automobile flameout, anti theft host sends the order of withdrawing a garrison, and makes radio receiving transmitting module, anti theft host, annunciator and ultrasonic range finder in running order.In the present embodiment, radio receiving transmitting module, anti theft host, annunciator and ultrasonic range finder all adopt prior art.No longer describe in detail.
