| titleOfInvention | A kind of detection device of parking space state and the detecting system of parking space state |
| abstract | The utility model provides a kind of detection device of parking space state and the detecting system of parking space state, including：It is arranged on the geomagnetic sensor and microwave detecting device in parking stall to be detected and being connected with each other；Geomagnetic sensor, for when detecting that the earth magnetism magnetic force parameter in parking stall region to be detected changes, generating drive signal and sending to microwave detecting device；Microwave detecting device, for receiving drive signal, the microwave signal of at least one frequency range is launched according to drive signal and receives the echo data returned, according to echo data, parking stall to be detected parking space state corresponding to Basic wave data and setting parking space state change threshold, determine the parking space state of parking stall to be detected situation of change and parking stall to be detected change after parking space state.Changes of magnetic field, the change of vehicle translational speed and the external environment that the utility model is not easy near by parking stall are influenceed, and are improved the degree of accuracy of testing result, be ensure that the low-power consumption of whole detection device, and cost is low. |
