交通控制指令生成模式

根据交通控制指令与交通拥挤问题、交通控制设施之间的关系,提出面向交通拥挤问题和面向交通设施的交通指令生成模式。分别对这两种模式的工作原理、工作流程、相关原则和使用范围进行了讨论,并将智能化的概念引入交通指令的生成过程中。结果表明,该方法可以极大减少交通管理人员的工作量,提高交通控制系统效率。

PLC Functional Instruction in Programming of the Application

In this paper, the function characteristics of instruction are introduced, and the focus is on contact compare instruction and the characteristics of the transfer instructions. With the traffic lights control as an example, this paper proposes the application of contact compare instruction and transfer instruction to program design method, making the program structure compact and statement concise. The control requirements are easily completed. Key words： Function Instruction; Programming; Traffic Lights; Contact Compare Instruction; Transfer
