Problems solved by technology

[0003] The monitoring of the main production equipment in the natural gas purification plant is generally based on temperature monitoring; when there is an abnormality in the moving equipment, the temperature will change in detail, especially when the temperature exceeds the limit, experienced maintenance engineers need to be on-site for inspection; because most The production equipment is placed on the terrace, and the temperature of the moving equipment changes significantly with the weather. The frequency of inspections by maintenance engineers is high and the efficiency is low.
[0004] With the widespread use of vibration sensors and their low procurement costs, vibration sensors have now been applied to the monitoring of dynamic equipment. However, at present, the data time nodes of temperature monitoring and vibration monitoring are not unified, the data types are incompatible, and the schemes are independent. The accuracy of early warning of dynamic equipment status is not high
