Embodiment Construction
[0025] The present invention will be further described below in conjunction with accompanying drawing.
[0026] see Figure 1 to Figure 6 , the present invention includes an embedded core that is a single-chip microcomputer, an LCD display interface circuit connected to the single-chip microcomputer, a button interface circuit, a sound interface circuit, an IC card (ie smart card) interface circuit, an ESAM interface circuit, a power carrier interface circuit and two groups of RS485 (communication module) interface circuit, and a power circuit for powering each circuit.
[0027] The IC card interface circuit completes the communication with the user card interface, and sends the data information to the embedded core, and the ESAM module circuit completes various security authentication operations such as data authentication, encryption, and decryption; the two sets of RS485 communication module interface circuits communicate with the embedded core respectively. The two groups...
