摘　　要：本文以欧姆龙CJ1M为例,用两种不同结构的顺序控制实现了人行道交通灯系统的控制,并对顺序控制中的小循环问题给出了解决方案。通过分析,指出对具体的控制对象,顺序的结构可以灵活变化。In this article, parallel and single sequential function chart were given to control the traffic lights, which was offered as a classical example of sequential control design. The small circulation was specially treated. After the analysis and comparison, the conclusion that the sequential structure was vivid and variable was acquired for the same system.
