摘　　要：介绍某型电台模拟训练器显示电路的设计过程。该电路以基于51内核的高性能单片机MSC1210单片机作为主控单元,通过虚拟I2C总线(Inter IC BUS)控制数码管驱动芯片SD7218,实现实际装备的频率及工作状态显示、存贮、调用及出错信息提示等功能,同时通过串行接口连接网络通信单片机实现与主控计算机的互联。The design process of display circuit for the transmitter - receiver simulator is introduced. The micro- controller MSC1210 with the enhanced 8051 core is used as the main control unit, which controls the display drive IC SD7218 through the virtual I^2C bus （Inter IC BUS）, as a result the functions such as displaying, storing, transferring,the frequency and working state, the error warning are realized as same as the real one. Through the serial interface port, the circuit is linked with the net communication micro - controller, and the interlink with the main computer is realized.
