The anti-disturbance question of the control system of the high frequency electric knife / 医疗卫生装备

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.
