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.
