【摘要】 高频电刀是在十分复杂的环境下工作的,如何保证系统的高可靠性,是高频电刀控制系统的一个重要问题。本文主要从硬件和软件2个方面简单介绍了高频电刀控制系统的抗干扰方法和措施。在硬件方面采用的技术有:正确选择微处理器,将印刷版合理分区,噪声屏蔽等。软件方面采用的技术有:设置软件陷阱,编制看门狗程序,数字滤波等。通过采用上述抗干扰措施,提高了系统的安全性和可靠性。更多还原

【Abstract】 The working condition of the high frequency electronic knife is quite complicated.How to ensure it to run unfailingly is an important demand in the design of the control system of the high frequency electronic knife.This paper introduces the anti-disturbance method and measure of the control system of the high frequency elec-tronic knife briefly.The hardware measure and software method are introduced mainly.In the aspect of hardware,the techniques include choosing microprocessor correctly,distributing printed-plank area reasonably,noise shield,etc.IN software,there are such as establishing the trap of program,designing program for Watchdog,digital filtering,Owing to adopting above anti-disturbance techniques,the safety and reliability of the whole system are improved.更多还原
