Description

technical field [0001] The invention relates to the field of parking space detection, in particular to a three-mode geomagnetic detection system and a method thereof. Background technique [0002] At present, the parking space detection device in the parking lot generally adopts the traditional geomagnetic detection method or a combination of infrared and pyroelectric methods. The method of geomagnetic detection belongs to the indirect measurement of the disturbance of the vehicle to the geomagnetic field. Its advantage is low power consumption. However, due to the inconsistency of the disturbance of the vehicle to the geomagnetic field, it cannot be well judged whether there is a vehicle parked in the parking space. Factors such as the iron content of the vehicle and the age of the vehicle will cause inconsistencies in the values ​​measured at the same location for the same type of vehicle. At the same time, the geomagnetic detection method also involves the environmental ...
