IR/RF LAYER SAM MCU MCU SYSTEM INTEGRATED WITH IR/RF COMMUNICATION MODULE LAYER MODULE AND SAM

摘要

Disclosed is an integrated main control unit (MCU) device performing a role for matching infrared (IR)/radio frequency (RF) communication, electronic payment (secure application module (SAM)), vehicle entry information, image photographing information, and communication information in a system such as a Hi-pass system, a traffic information providing system through a roadside base station, a smart tolling system, a wireless access for vehicular environment (WAVE), and the like. According to the present invention, the system comprises: integrated L2, L7 module units for IR/RF communications; the SAM for processing electronic payment; a cell plan control unit for controlling an antenna; and a signal synchronization unit for synchronizing a signal. Accordingly, a communication mode divided into each layer is integrated to remove a data transmission time for each layer and only authentication (SAM) required for billing is processed in internal communications, thereby processing data at high speed and removing data bottleneck.
