摘要
煤矿提升机是矿山生产至关重要的大型设备之一。针对传统提升机电控系统存在有级调速,提升机运行不平稳、可靠性低等问题,研究开发了基于PLC和嵌入式控制器互为冗余的"安全回路双线制"系统+上位计算机IPC监控和后备保护系统+数字化变频装置的新型全数字化、网络化电控系统,提高整个电控系统安全可靠性、控制精度及调速性能。
The mine hoist is one of the most important equipments. There are many problems in traditional electric controlled system, such as, step speed cotrol, poor speed controlling, elevator does not run smooth and low reliability etc. Researched and development the new digital and networked electronic control system, based on PLC and ＂two- security circuit＂ of redundancy system ＋ IPC top computer monitor and backup protection system ＋ digital variable- frequency devices, so as to raise the safety, reliability, control precision and speed regulation performance of the whole electric controlled system.
