一种双单片机激光功率控制系统的软件抗干扰方法
An Anti-Interference Software Method of the Dual MCU Laser Power Control System
摘要
以软件设计为主,将信号在单片机内部可能受到干扰的情况分为两个阶段,并创新性的提出通过双单片机结构自检识别受干扰信号的方式,有效的阻断错误信号的输出,大大降低了信号干扰所造成的不良事件发生率,提高了激光医疗产品功率输出的可靠性。
Abstract
The research study focused mainly on software design, dividing the possibility of signal interference in MCU into two mainsections. An innovative method proposed beinga “Self-Checking Control System”on output signal via Dual MCU approach. The “Self-Checking Control System ”functioned to effectively blocked the output of false signals, resulting in a significant reduction inoccurrence of adverse event due to signal interference and increases the reliability of laser medical devices.
