Abstract

The invention relates to a main board interface circuit of a police identity recognizer. The main board interface circuit comprises an ARM11 core board circuit, a memory circuit, a battery power supply circuit, a light crystal display (LCD) circuit, a camera circuit, a trans-flash (TF) card memorization circuit, a loudspeaker circuit, a receiver circuit, a microphone (MIC) circuit, a universal serial bus (USB) interface circuit, a keyboard interface circuit, a radio frequency identification (RFID) card reading circuit, a Bluetooth circuit, an SAM decryption module and a global positioning system (GPS) circuit, wherein the ARM11 core board circuit is respectively in two-way communication connection with the memory circuit, the LCD circuit, the camera circuit, the TF card memorization circuit, the USB interface circuit, the keyboard interface circuit, the RFID card reading circuit, the Bluetooth circuit and the GPS circuit; the ARM11 core board circuit is also respectively in two-way communication connection with the loudspeaker circuit, the receiver circuit and the MIC circuit; the battery power supply circuit is connected with the ARM11 core board circuit; and the SAM decryption module is in two-way communication connection with the RFID card reading circuit. The main board interface circuit of the police identity recognizer has functions of recognition and comparison of two generations of identity cards, voice data communication, photo-taking and image-shooting, GPS, Bluetooth transmission and the like.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a main board interface circuit of a police identification device. Background technique [0002] The ID card (including the first-generation resident ID card and the second-generation resident ID card) is an important certificate for recording basic personal information. The first-generation ID card belongs to the traditional visual-reading document, which can only be verified by visual reading, and it is difficult to judge the authenticity of the document. The second-generation ID card adopts non-contact IC card technology, which has two functions of machine-reading and visual reading. , which can realize the exchange of personal identity information and the security confirmation of identity information. [0003] Identity certificates are required to handle most of the business in banks, securities, customs, industrial and commercial taxation, civil aviation and other units....
