Only some special parking environments, such as: basement, roadside ..., which are waited, readily receives the vibration other than car engine or motor
Place, to prevent the low frequency sensing device 31 from accidentally surveying, in the vibration for receiving corresponding frequency band, this prolongs the low frequency sensing device 31
When detecting unit 311 detect the low frequency sensing device 31 must can transmission signal after low-frequency vibration continues for some time
To first judging unit 32, and then the probability accidentally surveyed is reduced, is sailed when first judging unit 32 judgement confirmation detects vehicle
Enter or be driven out to, then by 33 transmission signal of the first wireless communication unit to second radio receiving unit 51, and by this
Two control units 52 convert the standby unit 531 to detecting state, Jin Ertong the ground magnetic sensing devices 53 from dormant state
Whether have vehicle drive into or be driven out to, if the second judgment unit 54 judgement does not measure vehicle if crossing the ground magnetic sensing devices 53 and detecting again
, then second wireless communication unit 55 citation number is to first radio receiving unit 34, and first radio receiving unit 34 is again
Signal is reached into the first control unit 35, the low frequency sensing device 31 is re-started by the first control unit 35 and detects
It surveys；If the second judgment unit 54 judgement measures vehicle, 55 transmission signal of the second wireless communication unit to the cloud host machine
20 carry out storage data.
The utility model is first detected whether have vehicle by the lower low frequency sensing module 30 of power consumption, when this is low
The confirmation of frequency sensing module 30 has to be detected again with the earth magnetism sensing module 50 when vehicle, not only enables the earth magnetism sensing module 50
It is enough that the energy is saved in dormant state, the accuracy rate of detecting vehicle is more improved by secondary detecting.
More preferably, which can make the low frequency sensing device 31 after detecting a predetermined time,
It allows 31 transmission signal of low frequency sensing device to first judging unit 32, and then improves the standard of the low frequency sensing device 31 detecting
True rate.
