近年来国际上微电子和电力电子技术迅猛发展,从而使大型港口机械的电气装备不断地改进。本文就大型港口机械对电控技术的要求,介绍了全电子数字控制系统。对其组成部分:全数字化控制驱动装置、可编程序控制器、故障诊断及数据管理系统、数字化操纵给定检测等的性能特点、工作原理和应用等方面作了分析介绍。还对半自动操纵——最佳运行轨迹操纵和交流变频调速技术的应用作了介绍。
In recent years, the international microelectronics and power electronics technology is developing rapidly, so that the electrical equipment of large port machinery continues to improve. In this paper, the requirements of large-scale port machinery on electronic control technology, introduced the whole electronic digital control system. Its components: all-digital control of the drive, programmable logic controller, fault diagnosis and data management systems, digital manipulation of a given detection and other performance characteristics, working principle and application of the analysis were introduced. It also describes the application of semi-automatic maneuvering-best track maneuvering and AC variable frequency speed regulation.
