顺序控制器是继继电器控制系统、无触点固定逻辑控制系统和计算机控制系统之后出现的新型控制装置,它具有灵活性强、可靠性高、易学易懂、使用与维修方便、造价便宜等特点,且便于和计算机或其他繁简程度不同的工业自动化装置联用。自一九六九年美国数字设备公司(DEC)首先研制出世界第一台顺序控制器以来,顺控技术在国内外发展均很迅速。我厂原~#1高炉上料系统、上料卷扬采用继电器控制,槽下为人工驾驶称量车取料。槽下粉尘污染严重且夏闷冬冷,工人劳动条
The sequence controller is a new type of control device that appears after the relay control system, contactless fixed logic control system and computer control system. It has the characteristics of high flexibility, high reliability, easy to understand, easy to use and maintain, and low cost , And easy to use computer and other complex degree of different industrial automation devices together. Since the first digital controller in the world was first developed by Digital Equipment Corporation (DEC) in 1969, Shun Technology has developed rapidly at home and abroad. I plant the original ~ # 1 blast furnace feeding system, the feed hoist using relay control, the tank for artificial driving weighing car take material. Under the tank dust pollution and summer boring winter cold, workers labor
