RFID (radio frequency identification) synchronous image snapshot controller

Abstract

The invention discloses an RFID (radio frequency identification) synchronous image snapshot controller. According to the RFID synchronous image snapshot controller, an RFID remote reader-writer of an electronic car license system is connected with a bayonet and a high-definition camera of an electronic police system, so that work that the reader-writer reads electronic car license information of a car to trigger the high-definition camera to perform snapshot, further identification of license numbers and the like is realized. The controller comprises a control chip module, a relay switch output module, a temperature detection module, a voltage detection module, an input interface group, an output interface group and a control interface group. When the RFID reader-writer identifies an electronic car license preassembled on the car, a GPO (group policy object) signal is output and is taken as a control signal to be input to the synchronous image snapshot controller, at the moment, the synchronous image snapshot controller can adjust delay time of a trigger signal or output pulse width and period of TTL (transistor-transistor logic) levels according to the actual application environment of the camera, and then the signal is output to the matched camera, so that synchronous trigger or delay trigger is realized for snapshot.

Description

technical field [0001] The invention relates to the field of traffic vehicle management, in particular to an RFID synchronous image capture controller. Background technique [0002] At present, more and more electronic license plates based on the latest RFID radio frequency identification technology are appearing in the intelligent traffic management of cities and highways. The electronic license plate system writes vehicle information into UHF electronic tags, and realizes long-distance identification of vehicle information in electronic tags through UHF long-distance readers distributed at intersections or on roads. The identified vehicle information realizes the intelligent management of the vehicle. [0003] In common road checkpoints and electronic police monitoring systems, there are mainly two modes: coil triggering and video detection. The scalability and applicability of the coil detection system function is small, it needs to rely on external hardware to trigger ...

AI Technical Summary

Problems solved by technology

[0005] The RFID synchronous image capture controller of the present invention connects the radio frequency identification long-distance reader-writer of the electronic license plate system with the bayonet and the high-definition camera of the electronic police system, so as to realize reading the vehicle electronic license plate through the radio-frequency identification long-distance reader-writer information to trigger high-definition camera capture and further license plate number recognition, etc., not only can solve the problems of low trigger accuracy, high cost, and difficult implementation of the trigger methods of existing camera-related equipment, but also can completely solve the problem of fake and fake license plates. , blacklisted vehicles, and vehicles operating illegally
