Problems solved by technology

At present, vehicle detection through geomagnetic signals is usually used for vehicle early warning, and is rarely used in vehicle parking spaces. The main problem is that the existing geomagnetic detection devices are used in the parking lot environment, which has high cost, low efficiency, and low accuracy. Shortcomings

Embodiment 1

[0027] A geomagnetic vehicle detector such as Figure 1-2 As shown, it includes an MCU device 100, a wireless transmission module 200 and a geomagnetic detection module 300;

[0028] The MCU device 100 is used to control the working state and operating frequency of the wireless transmission module 200 and the geomagnetic detection module 300, and can control the data transmission between the wireless transmission module 200 and the geomagnetic detection module 300; the MCU part mainly includes a low-power single-chip microcomputer and its peripheral circuits. The MCU model is an IC chip produced by Texas Instruments. The chip used by the MCU needs to meet the conditions of a 16-bit ultra-low power chip, because the detector needs to be buried in the ground and powered by a battery, and the standby current of the chip is extremely small. Therefore, the long-term stable operation of the geomagnetic detector can be guaranteed.

[0029] The wireless transmission module 200 is us...

Abstract

The invention relates to a vehicle detection device and discloses a geomagnetic vehicle detector. The geomagnetic vehicle detector comprises an MCU device, a wireless transmission module and a geomagnetic detection module. The MCU device is used for controlling working states and working frequencies of the wireless transmission module and the geomagnetic detection module and can control data transmission between the wireless transmission module and the geomagnetic detection module. The wireless transmission module is used for receiving a geomagnetic signal detected by the geomagnetic detection module and uploading the geomagnetic detection module to the data side though a radio-frequency transceiver. The geomagnetic detection module comprises at least two geomagnetic sensors and is used for detecting the geomagnetic signal. The geomagnetic sensors are sensors capable of detecting at least three directions and can transfer the detected geomagnetic signal to the wireless transmission module. The geomagnetic vehicle detector has the advantages of being simple in structure, convenient to process, quick and convenient to install and having good application value.

Description

technical field [0001] The invention relates to a vehicle detection device, in particular to a geomagnetic vehicle detector. Background technique [0002] With the rapid development of cities and the improvement of people's living standards, the number of various vehicles continues to increase, followed by a corresponding increase in the demand for parking spaces in major business districts and residential areas of the city. The emergence of large parking lots has solved the problem of difficult parking in cities, but at the same time it has also brought a series of problems such as the difficulty of managing parking spaces in large parking lots. In order to realize real-time detection of parking spaces in large parking lots, that is, to detect whether there is a vehicle parked in a certain parking space, a variety of parking space detection technologies have been developed. [0003] The principle of using geomagnetic signals to detect vehicles is that the ferromagnetic sub...
