Embodiment Construction
[0036] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
[0037] Geomagnetic sensors can be used to detect the presence of vehicles. Since the chassis of a car contains a lot of metal, generally, a geomagnetic sensing module including a geomagnetic sensor is installed on the ground to detect changes in the magnetic field above the geomagnetic sensing module. However, if the geomagnetic induction module is installed on the ground, it is easy to be run over by passing vehicles, causing damage to the geomagnetic induction module.
[0038] In view of the above problems, the inventors of the present application propose the following embodiments to solve the above problems after research and exploration.
[0039] see figure 1 , the embodiment of the present application provides a vehicle detection device 100 , including: a first support rod 10 , a second suppo...

The invention provides a vehicle detection device and a vehicle detection system, and the device comprises a first supporting rod and a second supporting rod which are disposed at a side surface of aparking space and are perpendicular to the ground; a middle shaft rod, arranged between the first supporting rod and the second supporting rod, and the two ends of the middle shaft rod being connectedwith the first supporting rod and the second supporting rod respectively, the middle shaft rod being parallel to the ground; and a geomagnetic induction module, fixedly connected with the middle shaft rod, and the geomagnetic induction module being used for detecting the magnetic field change of the side surface of the parking space. According to the device, through the first supporting rod and the second supporting rod which are perpendicular to the ground and the middle shaft rod with the two ends connected with the first supporting rod and the second supporting rod respectively, the groundmagnetic induction module can be installed on the side face of a parking space, and compared with the prior art that the ground magnetic induction module is laid on the ground surface, the ground magnetic induction module is prevented from being rolled by a vehicle.
Description
technical field [0001] The present application relates to the technical field of sensors, in particular, to a vehicle detection device and a vehicle detection system. Background technique [0002] Geomagnetic sensors can be used to detect the presence of vehicles. Therefore, geomagnetic sensors play a very important role in traffic monitoring systems. Since the chassis of a car contains a large amount of metal, usually, a geomagnetic sensing module including a geomagnetic sensor is laid on the ground to detect changes in the magnetic field above the geomagnetic sensing module. However, if the geomagnetic induction module is laid on the ground, it is easy to be crushed by passing vehicles, resulting in damage to the geomagnetic induction module. Contents of the invention [0003] The purpose of the embodiments of the present application is to provide a vehicle detection device and a vehicle detection system to improve the problem of "installing the geomagnetic induction m...
