Problems solved by technology

Wireless detection receivers generally can only receive signals from about 30 wireless vehicle detectors within a communication distance of 100 meters, and are vulnerable to external wireless interference and object blocking, high power consumption, and short battery life.
For example, installing an intelligent parking system in a parking lot requires a large number of vehicle inspection receivers, which makes the entire system network complex and the system cost is high

Abstract

The invention provides a wireless geomagnetic vehicle detection device and system, and relates to the field of vehicle detection devices. The wireless geomagnetic vehicle detection device comprises an information collection module, a communication module and a control module, the information collection module is coupled with the control module and used for collecting parking information of a vehicle, the control module is used for generating an analysis result according to the parking information of the vehicle, and the communication module comprises an NB-IoT unit and an antenna and is used for sending the analysis result to a network. According to the wireless geomagnetic vehicle detection device, through the usage of the NB-IoT unit, a signal relay station does not need to be installed, massive connections can be established, the device has the advantages of being not easy to interfere with, low in power consumption and long in service life, and the construction and maintenance costs are saved. The system comprises a server, a client side and the wireless geomagnetic vehicle detection device, and the wireless geomagnetic vehicle detection device is connected with the server through a public mobile base station. The system supports connections of massive devices and is wide in application range.

Description

technical field [0001] The invention relates to the field of vehicle inspection devices, in particular to a wireless geomagnetic vehicle inspection device and system. Background technique [0002] With the acceleration of traffic construction at home and abroad, intelligent transportation has become the inevitable development direction of urban traffic management, and it is an important aspect to alleviate traffic congestion and improve transportation and management efficiency. The basis of building an intelligent transportation system is the collection of road traffic information. An excellent road traffic information collection method is the strong backing for the release of road traffic information and the cornerstone of the intelligent transportation system. [0003] At present, there are a variety of traffic information collection technologies and products on the market, mainly including ground sensing coils, microwaves, video, geomagnetism, etc., responding to differen...
