Hệ thống giám sát tình trạng máy

What is machine health monitoring?

Theo dõi tình trạng máy là một hệ thống quản lý thông minh, liên tục thu thập các thông số vận hành thiết bị thông qua nhiều cảm biến khác nhau và sử dụng các công nghệ phân tích dữ liệu để đánh giá tình trạng thiết bị và dự đoán lỗi. Hệ thống chủ yếu giám sát các thông số quan trọng của thiết bị điện bao gồm nhiệt độ, rung động, thông số điện, và các chất chỉ thị hóa học, establishing equipment health models to achieve early fault warning. This system comprises four core components: lớp thu thập dữ liệu, lớp truyền thông, data processing layer, and application service layer.

Tại sao chúng ta cần theo dõi tình trạng máy?

Traditional planned maintenance and post-failure repair models suffer from high maintenance costs and low equipment availability. Statistical data shows that economic losses from unexpected equipment failures are 3-5 times higher than planned maintenance costs, with unplanned downtime costing tens of thousands to hundreds of thousands of dollars per hour. Machine health monitoring systems can detect equipment anomalies in advance, eliminating faults at their inception and fundamentally transforming equipment maintenance approaches from “fix when broken” đến “bảo trì dự đoán”.
