摘要
本实训项目设计说明书针对注塑机的发展前景,结构组成,工作原理,液压系统设计,集成设计及其PLC控制技术的介绍。可编程序控制器PLC是微机技术与传统的继电接触控制技术相结合的产物,它的控制系统可靠性高,抗干扰能力强、功耗低、通用性和灵活性高,可编程控制器以体积小功能强大所著称,它不但可以很容易地完成顺序逻辑、运动控制、定时控制、计数控制、数字运算、数据处理等功能,而且可以通过输入输出接口建立与各类生产机械数字量和模拟量的联系,,由于信息、网络时代的到来,扩展了PLC的功能,使它具有很强的联网通讯能力,从而更广泛地应用于众多行业。
关键词:集成设计、PLC控制技术、可靠性高、抗干扰能力强、功耗低、通用性、灵活性高
Abstract
The machine is introduced, and the working principle, structure, integrated design of hydraulic system design and PLC control technology. PLC programmable controller is the technology with traditional puter relay contact control technology, it is the e of bination of the control system has high reliability and anti-interference capability is strong, low power consumption, high universality and flexibility, programmable controller to small powerful functions, it is not that can easily finish order logic, motion control, timing, counting control, puting and data processing and so on the function, and can be established through input/output interface with various production machinery digital and analog connection, so as to realize the automatic control of the production process. Especially now, due to the arrival of the era of information, network, expanding the function of PLC, to make it munication ability, thus more widely applied in many industries.
Keywords: integrated design, PLC control technology, high reliability and anti-interference capability is strong, low power consumption, generality, high flexibility
