矿井提升机盘闸制动系统安全在线监控

就矿井提升机盘闸制动系统的功能、结构、制动要求以及在提升系统中所处的地位和国内外研究现状进行了相关介绍与说明,运用故障树分析讨论了影响提升机制动系统性能的各种因素,对其安全监控系统技术进行了研究。根据故障树分析的结果,结合实际情况得出对应状态下可监测的物理量,运用现代控制方法建立系统在线监测的模型。最后通过工控软件MCGS完成整个监测系统,实现各项监测数据在线显示,某些物理量的监测与报警,重要参数的存储与调取,运行故障的记忆与查询等功能,以实现制动系统安全的在线监控。

On-line Safety Monitoring for Disk Braking System of Mine Hoisting Machine

The function and structure of disk braking system of mine hoisting machine is introduced in the paper, as well as braking requirements, importance of hoisting machine in the system and research status at home and abroad.The influencing factors of disk braking system are analyzed with failure tree, and the research on safety monitoring system technique is made.Combining the failure tree analysis with practical situation, it is concluded that physical quantity being inspected in corresponding situation is obtained and on-line monitoring model is established with modern control method.The monitoring system is developed by industrial control software to achieve on-line data monitoring display, monitoring and alarm of given physical quantity, storage &; fetch of important parameter, and search of operating trouble record so as to realize the online monitoring safety of braking system.
