摘要
激光手术器的微机控制系统用微机代替了模拟闭环系统的预置、比较和调节等环节,实现DDC控制。硬件设计采用了可编程接口PIA和VIA,使得硬件结构简单而可靠;软件设计采用了中断技术使得系统具有实时性,达到无超调和给定稳态精度的指标。
The microcomputer controlling system of laser surgical instrument replaces presetting comparision and regulation in analogue closed-loop system with microcomputer. It performs DDC In the hardware design the programmable interface PIA and VIA is used. it makes the hardware structure very simple and reliable. In the software design. the interrupter technology is used. it makes system a real-time one. and to attain the target for unovershoot and given steady-state precision.
