基于PLC的自动送料装车控制系统的设计 学生： 指导教师： 摘要：随着微处理器、计算机和数字通信技术的飞速发展，以微处理器为基础的通用工业控制装置——可编程序控制器（Programmable controller）简称PLC，由于PLC的，PLC 送料小车 控制 程序设计 The design of controlling in the automatic feed loading system based on plc Abstract: With the microprocessor, computer and digital communication technology, the rapid development of microprocessor-based general-purpose industrial control devices -- programmable controller (Programmable controller) referred to as the PLC, the PLC, high reliability, adaptability to environment strong, flexible and versatile, easy to use, simple maintenance, has been widely used in various mechanical equipment and production process of automatic control system. Of early PLC, the place where there are relays, can be used. While little can be said of todays PLC control system who need a place there needs to PLC. Especially in recent years, PLCs cost, feature segments without enhancement, therefore, the current PLC at home and abroad has been widely used in various industries. This design uses PLC control servo motor, the servo motor movement strong anti-interference ability, high reliability and work to achieve loading system feeding the car into manual and automated, manually change the past, the simple car feed, and industrial processes can be the need to implement the automatic cycle car control, reduce labor, increase production efficiency, automated production; the same time, as a result of the modular structure, the system constitutes a highly flexible, easy online change, product adaptability. And this car is designed to feed the poor working conditions, are not allowed to enter the working environment nurtured by the circumstances.
