Data Transmission and Control for Optimized Library’s Books Administration System Based on RFID Technology 【Abstract】A new solution of the data transmission and control for optimized library’s books administration system based on RFID (radio frequency identification) technology is described in this paper. This paper describes the principle and block diagram of systematic hardware in brief first. And then it gives the detailed introduction to the principle of MCU (Microprogrammed Control Unit) and the function and characteristic of various kinds of chips used, such as RS-232 interface, MAX202 chip and S6700 chip. munication interface between MCU and PC, the programming flow and the process of implementation are presented. While in the part of MCU and S6700 chip, the time sequences of data transmission and clock exchange are simulated by using the bit operation instructions of AT89C52 MCU. Every function module is de
