摘　　要：介绍一种以计算机和单片机为上-下位机结构的电子胸卡设计。通过上位机软件控制系统提取汉字点阵数据,发送显示控制命令。下位机由LPC900系列单片机和LED显示屏的硬件驱动电路构成,存储点阵数据和控制动态显示。上位机与下位机之间利用红外串行通信完成数据传输。该显示系统具有体积小,质量轻,功耗低和使用方便等特点。A new system for electronic badge is described in this paper,which is based on the upper and lower computer structure.The focus of host computer design is the extraction of Chinese characters dot-matrix data and the transmission of display and control commands.The lower computer has already accomplished dynamic LED display design with LPC900 series single-chip and the hardware drive circuit of LED display.The system uses infrared serial communication to complete data transmission.This system also gets other extraordinary characteristics like small size（45×80×3mm3）,light weight,low（power） consumption,simple operation and so on.
