一、前言随着计算机技术、通讯技术、集成电路技术的飞速发展,以全数字式现场总线技术为代表现场控制仪表、设备大量应用,使得传统的现场控制技术及现场控制设备发生了巨大的变化。繁琐的现场连线被单一、简洁的现场总线网络所替代,系统设计灵活、设备维护简单,信号传输质量也大幅提高。电子技术的飞速发展及在工程机械上的广泛应用,使得工程机械的智能化程度越来越高,特别是在控制器技术被引入工程机械控制领域后,给工程机械的发展带来了划时代的变化,工程机械的操作便利性、安全性、燃油经济性都得到了大幅提高。
I. Preface With the rapid development of computer technology, communication technology and integrated circuit technology, a large number of applications of on-site control instruments and devices represented by all-digital field bus technology have made great changes in the traditional on-site control technology and on-site control equipment . Tedious field wiring is a single, simple field bus network replaced by flexible system design, equipment maintenance is simple, signal transmission quality is also greatly improved. The rapid development of electronic technology and its widespread application in construction machinery make the degree of intelligent construction machinery more and more high, especially in the control technology has been introduced into the field of construction machinery control, to the development of construction machinery has brought a landmark Changes, construction machinery operation convenience, safety, fuel economy have been greatly improved.
