矿井作业中排水功能的完整性直接影响井下人员的生命安全。文章将以此为出发点,介绍一套基于集散式控制法的新型排水设备监测和故障诊断系统。该系统分为多极模块,并且构建出基于多参数设计的模糊综合决策法。经过实际验证,该系统性能良好,反应灵敏,为提高井下作业的安全性做出了极大的贡献。 The integrity of the drainage function in mine operations directly affects the life safety of miners. This article will take this as a starting point, introducing a set of new drainage monitoring and fault diagnosis system based on distributed control method. The system is divided into multi-polar modules, and build fuzzy comprehensive decision-making method based on multi-parameter design. After the actual verification, the system has good performance and responsiveness, and made great contribution to improve the safety of downhole operation.
