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的可靠性高、环境适应性强、灵活通用、使用方便、维护简单,已经广泛应用在各种机械设备和生产过程的自动控制系统中。对早期的PLC,凡是有继电器的地方,都可采用。而对当今的PLC几乎可以说凡是需要控制系统存在的地方就需要PLC。尤其是近几年来,PLC的成本下降,功能又不段增强,所以,目前PLC在国内外已被广泛应用于各个行业。
本设计采用PLC控制伺服电机,使伺服电机动作的抗干扰能力强,工作可靠性高,实现送料装车系统的小车的手动和自动化的转化,改变以往小车的单纯手动送料,并且可以按工业流程的需要实现小车的自动循环控制,减少了劳动力,提高了生产效率,实现了自动化生产;同时,由于实现了模块化结构,使系统构成十分灵活,便于在线修改,产品的适应性强。而且本送料小车的设计是由于工作环境恶劣,不允许人进入工作环境的情况下孕育而成的。

The design of controlling in the automatic feed loading system based on plc
Abstract: With the microprocessor, computer and munication 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 today's PLC control system who need a place there needs to PLC. Especially in recent years, PLC's 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
