基于闭塞系统的流水线控制指示系统设计
Design of Assembly Line Control and Indication System Based on Block System

闭塞系统最初是用于轨道交通中为防止列车追尾的一种防护系统，通过对各个区间信号灯控制以达到安全防护的目的。本文通过移植闭塞系统这一优秀的防护理念，利用51单片机在工厂流水线上重新设计。将流水线分为多个区间进行多段分控，以解决工厂流水线在实际的运行过程中由于速度不变且各个工位的实际操作效率不统一，产生后工位等待前工位或后工位错过工件的问题。利用单片微控制连接控制按钮达到对分区流水线的设计，再通过单片微控制器进行位置信息的处理。以达到指示和控制流水线的目的，实时动态操作流水线以提高生产效率为目的。
Block system was originally used in rail transit to prevent train rear-end collisions. It achieves the purpose of safety protection by controlling the signal lights in each section. By transplanting the excellent protection concept of block system, this paper uses 51 single-chip microcomputer to redesign the factory assembly line. The assembly line is divided into multiple sections for multi-section control, so as to solve the problem that the rear station waits for the front station or the rear station misses the workpiece due to the constant speed and the inconsistent actual operation efficiency of each station in the actual operation process of the factory assembly line. The design of partition pipeline is achieved by connecting control buttons with single-chip microcontroller, and then the position information is processed by single-chip microcontroller. In order to achieve the purpose of indicating and controlling the pipeline, real-time dynamic operation of the pipeline is for the purpose of improving production efficiency.
