Abstract

The invention mainly relates to the field of intelligent traffic, and, more specifically, relates to a wireless geomagnetic induction vehicle detection device. The device employs coil induction, wireless transmission, employs a battery for power supply, is small in thickness and size, is directly installed on the surface of a parking space, and does not need to carry out the segmentation of a road surface. Moreover, the device employs the geomagnetism principle for judging the movement of a vehicle: starting the geomagnetic induction judgment when the vehicle moves, thereby achieving the superlow power consumption use of the device, and achieving the super-long standby time. The output end of an induction coil of the device is connected with the input end of an induction controller, and the output end of the induction controller is connected with the input end of a wireless communication module. The output end of a battery is connected with the input end of a power management module, and the output end of the power management module is connected with the induction controller, the induction coil and the input end of the wireless communication module. The induction detection module and a geomagnetic detection module are connected with a single-chip microcomputer.

Description

technical field

[0001] The present invention mainly relates to the field of intelligent transportation, and more specifically, relates to a wireless ground sensing vehicle detection device and method. Background technique

[0002] In the field of smart parking, especially on-street parking, the detection of vehicle presence is an indispensable part of the entire system. As the problem of parking difficulties continues to intensify, the number of parking spaces increases, and the demand for vehicle detection devices increases. The performance requirements of vehicle detection devices are getting higher and higher. Currently used detection devices include geomagnetic sensors, video cameras, ground sensing detectors, and microwave sensors. Different sensing methods have different advantages and disadvantages. The geomagnetic sensor is small in size, low in power consumption, and convenient for construction, but it is susceptible to environmental interference, especially near ...
