摘　　要：气动行程程序设计是气压传动教学中的重要内容,其中如何消除障碍信号是教学中的重点和难点。现在主流的消障方法依然停留在采用脉冲信号和辅助阀上,随着新技术、新产品的出现,消障方法变得多样化。对比脉冲信号法、辅助阀法,以具体例子说明气动行程程序设计中出现Ⅰ型障碍采用串联法、气控延时阀以及气动节拍器进行消障的基本原理,并给出设计回路图。最后在总结各种消障方法优缺点的基础上提出消障方法的选择应综合考虑实际应用场合、使用要求以及经济成本的整体情况来选取。The design of pneumatic controlling program is an important content of the pneumatic transmission teaching,and the difficulties of teaching is how to remove obstacles signals.The mainstream ways to remove obstacles are still pulse signal and auxiliary valve.With the emergence of new technology and new products,the ways to remove obstacles become diversified.Compared with the pulse signal and auxiliary valve,this paper expands the basic principles of designing pneumatic controlling program with specific examples:series process is used against the I-type obstacle,and time delay valve based on pneumatic control and pneumatic stepper are used against obstacles.It shows the design circuit diagram and finally summarizes the advantages and disadvantages of various ways to remove obstacles and puts forward that the removing ways should be selected by combining with the practical application places,requirements and the costs.
