Integrated vehicle-mounted label detection system and method

Abstract

The invention relates to an integrated vehicle-mounted label detection system and method. The system is characterized in that a vehicle-mounted label is a strong magnet integrated vehicle-mounted label and comprises a strong magnet, an MCU, a Bluetooth communication module and a battery, wherein the MCU is in bidirectional connection with the Bluetooth communication module, the Bluetooth communication module is internally provided with an RSSI detection module, the battery supplies power to the MCU and the Bluetooth communication module respectively, and the vehicle-mounted label is absorbed near a central point of a chassis of a vehicle body through the strong magnet. The system is advantaged in that by changing the relative position relationship between the vehicle-mounted label and a geomagnetic parking space detection module, the vehicle-mounted label is installed near the center point of the chassis of the vehicle body, a distance between the vehicle-mounted label and the geomagnetic parking space detection module is very short, the vehicle-mounted label and the geomagnetic parking space detection module are combined, environmental interference in the prior art is shielded, linear propagation of wireless signals is guaranteed, the shortest distance between the vehicle-mounted label and the geomagnetic parking space detection module is guaranteed, and therby the vehicle-mounted label and a parking space detector are bound uniquely, and the unexpected technical effect is generated.

Description

technical field [0001] The invention belongs to the technical field of vehicle labels, in particular to an integrated vehicle label detection system and method. Background technique [0002] The passive fully automatic parking charging method using vehicle tags is currently a more commonly used charging method. Passive fully automatic toll collection only needs to install a vehicle-mounted device on the car. The vehicle-mounted device is passively triggered by the parking lot toll detector or parking space detector. Then the server background binds the car owner's information, and then completes the payment. [0003] The Chinese patent document with the patent application number 201310059553.X discloses a parking lot charging method based on RSSI positioning. The specific method is: install a vehicle tag in the cab of the vehicle, and use the current parking space detection node to be located approximately in front of the vehicle tag , and the adjacent parking space detect...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art, and propose an integrated on-vehicle tag detection system and method to solve the problem that the RSSI signal in the prior art is easily disturbed by the environment during the propagation process, and the positioning accuracy is still not accurate enough
