Electronic license plate system based on active radio frequency recognition and communication control method thereof

Abstract

The invention discloses an electronic license plate system based on active radio frequency recognition and a communication control method thereof, relating to the technical fields of an active radio frequency recognition technology and a vehicle management technology thereof. The electronic license plate tag can detect the existence of an electronic driver tag in real time, obtain data of the electronic driver tag and send the self data and the data of the electronic driver tag together to a reader-writer; the electronic license plate tag starts detecting the electronic driver tag after beingawakened from a dormant state at a set period, and the electronic driver tag is awakened from the dormant state at the set period and sends the self data; and the electronic license plate tag can automatically regulate an awakening clock to realize the function of synchronous low-power consumption reception with the awakening clock of the electronic driver tag. The electronic driver tag is directly subjected to information interaction with the electronic license plate tag, and the state information fed back to the reader-writer by the electronic license plate tag ensures that managers can achieve the purposes of effective vehicle management, real-time monitoring, vehicle recognition, vehicle burglary prevention and the like.

Description

Technical field [0001] The invention involves short -distance wireless communication micro -power control technology and vehicle management technology fields in radio frequency recognition technology, especially an electronic license plate system and their communication control methods based on active radio frequency recognition. Background technique [0002] With the development of the Internet of Things technology, the application of wireless radio frequency recognition technology is currently very common in vehicle management. At this stage, there are three main types of vehicle anti -theft management solutions: [0003] Plan 1. By installing a anti -theft alarm device on the body, the owner uses the remote control to make the vehicle monitoring. When the vehicle is touched by other people and the object, the mild vibration switch on the device will be triggeredAnd car owners can cancel the monitoring alarm through the remote control. [0004] Scheme 2. Install GPS and GSM and...

AI Technical Summary

Problems solved by technology

The above scheme 1 can avoid vehicle theft to a certain extent by installing a low-cost alarm device, but when the owner is far away from the vehicle body, the alarm information on the vehicle body may not be transmitted to the vehicle owner, and this scheme cannot build a vehicle management system platform; scheme 2 Real-time monitoring and management of vehicles can be carried out by using advanced technical means such as mobile communication technology and satellite positioning technology on the vehicle body, but the cost of the entire system is very high and cannot be popularized; scheme 3 uses radio frequency identification technology, although the cost is relatively low, it is also Solved the problem of information collection, but the reader needs to read the license plate and driver's tag at the same time to judge the matching status, the process is complicated

Especially in the case of intensive vehicle monitoring, to determine the matching status of a license plate label, it is necessary to search for all collected driver labels. Not only will the collection rate be relatively low, but it is also not conducive to quickly identifying illegal vehicle targets.
