【Abstract】 The characteristic of the intefference in the industrial environment is discussed and the anti-interference strategies are presented according to the experiences in the industrial environment. The better effectiveness of interfernce-free will be gotten as long as the related interfernce-free strategies are adopted in the design of the software. The reliability will be enhanced if the hardware methods are combined with the software methods.更多还原
