Abstract
The utility model discloses a communication circuit of a base and a decryption device of a second generation identification card reader. The communication circuit comprises a card reading antenna, an analog-to-digital converter, a central processor a, a wireless communication module a, a security module, a central processor b and a wireless communication module b, wherein the card reading antenna, the analog-to-digital converter, the central processor a and the wireless communication module a are arranged on the base, and the security module, the central processor b and the wireless communication module b are arranged on the decryption device. The wireless communication module a is connected with a signal antenna a. The wireless communication module b is connected with a signal antenna b. The signal antenna a and the signal antenna b are connected with a wireless network. According to the utility model, the base and the decryption device of the reader are separated, thus the volume and the weight of the base are reduced; and the communication between the base and the decryption device is carried out with the wireless network, thus setting up a wire circuit is unnecessary, and the carrying and the use are convenient.
Description
Technical field
The utility model relates to the communicating circuit of a kind of China second-generation identity card reader base and decryption device.
Background technology
Along with popularizing of second generation I.D., the use of China second-generation identity card reader has also more and more widely become one of indispensable office appliance in a lot of fields such as public security, work attendance, employee's management.After card reading antennas in the identity card reader reads ID card information,, be stored in the storer through data processing; In the process of deciphering identification, security module is called the I.D. data that read and is deciphered, discerns and verify; Therefore, card reading unit and decrypting device are two ingredients that complete reader ID card verification system is indispensable.
Carry out data communication through wired mode between traditional reading device base and the decryption device, decryption device is after the enciphered message deciphering, and the ID card information after will deciphering through communication line returns to the reader base.Yet it is very inconvenient that wired communication line uses, and carries also pretty troublesomely, restricted reader use in many instances.
The utility model content
The purpose of the utility model is to solve the deficiency of communicating circuit between existing China second-generation identity card reader base and the decryption device; A kind of China second-generation identity card reader base of novel radio mode and the communicating circuit of decryption device are provided; Overcome between traditional identity card reader base and the decryption device and take the wire communication circuit, use and carry very shortcoming such as inconvenience.
The purpose of the utility model realizes through following technical scheme: the communicating circuit of China second-generation identity card reader base and decryption device; It comprises card reading antennas, analog to digital converter, central processing unit a and the wireless communication module a that is located on the base, and is located at security module, central processing unit b and wireless communication module b on the decryption device; The output of card reading antennas is connected with the input of analog to digital converter, and the output of analog to digital converter is connected with central processing unit a, and central processing unit a is connected with wireless communication module a, and wireless communication module a is connected with signal antenna a; The output of security module is connected with central processing unit b, and central processing unit b is connected with wireless communication module b, and wireless communication module b is connected with signal antenna b; Be connected through wireless network between signal antenna a and the signal antenna b.
Described wireless communication module a of the utility model and wireless communication module b are the 2.4G wireless communication module.
The beneficial effect of the utility model is: the base and the decryption device of reader are separated, reduced the volume and weight of base, carry out communication through wireless network between base and the decryption device, need not to set up Wireline, use and carry more convenient.
