机器状态监测
概述
机器状态监测是监测振动和温度等参数的过程，以识别表明性能下降或即将发生故障的变化。它是预测性维护解决方案的必要组成部分，允许在发生故障之前安排维护，或采取其他措施来防止机器损坏和生产损失。除了改进维护计划之外，状态监测还提供了价值。例如，提高对机器操作的可见性可以指出产品缺陷的根本原因，并可以支持能源消耗的优化。
适用行业

Case Study
ASD Healthcare Delivers True Connected Care
ASD Healthcare’s Cubixx connected refrigeration solution was initially aimed at larger hospitals and pharmacies, utilising Wi-Fi or local area networks (LAN) for connectivity. With phase two, Cubixx would be rolled out to smaller practices and patients homes. The issue for ASD Healthcare was finding a single connectivity provider to cover the entire U.S., and facilitate international expansion.

Case Study
Machine Condition Monitoring for a Caribbean Resort
A Caribbean resort has numerous buildings spread out across a scenic campus. One of the company's most important concerns is reliable air conditioning, as guests will be very upset if they are uncomfortable. Downtime is not an option. But if air conditioning equipment fails completely - a compressor, for example - the replacement has to be shipped in from another country at an inflated price. The resort realized that closely monitoring their equipment would enable preventative maintenance, and greatly extend the useful life of their air conditioning systems. But how do you monitor things like pumps and compressors when they have no network interface and they are scattered across a very wide area?
