Abstract
The invention relates to a passive parking space detection device based on an enhanced magnetic field. The passive parking space detection device comprises a nonmagnetic substrate, nonmagnetic hollow balls, magnetic balls and a geomagnetic sensor. The magnetic balls are arranged in cavities of the nonmagnetic hollow balls through hollow-out places in the bottoms of the nonmagnetic hollow balls respectively. Adhesive is coated on grooves of the nonmagnetic substrate; the nonmagnetic substrate and the nonmagnetic hollow balls, which are internally provided with the magnetic balls, are inverted to enable the magnetic balls to fall to the top portions of the nonmagnetic hollow balls so as to prevent the magnetic balls in the nonmagnetic hollow balls from making contact with the adhesive; and then, the adhesive is applied between the nonmagnetic hollow balls and the grooves of the nonmagnetic substrate for adhesion and fixation, and after the adhesive finishes adhesion and is dried, the structure restores and is placed upwardly. The device improves parking space monitoring accuracy effectively and reduces detection energy consumption.
