摘　　要：针对高频电刀具有的结构比较复杂,采集和控制的数据量比较多的难点,提出了一种在多个单片机结构下的医用高频电刀设计及其配套的自动测试系统。数据采集、主控制、射频控制、用户界面分别采用独立的单片机控制。各个单片机之间分工协同工作,通过串行接口USART和SPI,并根据约定的通信协议进行通信;射频产生电路由负责射频控制的单片机控制复杂可编程逻辑器件(CPLD),从而产生控制功率驱动电路的方波。经测试,该系统输出频率稳定,系统参数灵活可调,且提高了高频电刀的实时性和安全性。Because of the high frequency gleetric knife structure is more complex, data acquisition and control than more difficul- ty, we propose a high - frequency electric knife designed for medical and supporting the automatic test system under multiple MCU structure. Data acquisition, master control, radio control, user interface were used to separate MCU control. The division of work be- tween the various microcontroller via a serial interface USART, SPI, and communicate communication protocol in accordance with the agreement; RF generator circuit complex programmable logic device （CPLD） is responsible for radio -controlled by the MCU control, power driver circuit to generate control the square wave. After testing, the system output frequency stability, flexible and adjustable system parameters, and to improve the high -frequency electric Knife timeliness and safety.
