Vibration monitoring system and method based on WIA-PA and 4G double wireless technology

Abstract

The invention relates to a vibration monitoring system and method based on a WIA-PA and 4G double wireless technology, and the system comprises an upper computer and a server of an upper control layer, a program is stored in the upper computer, the steps of the method are executed when the program is loaded, fault grade evaluation and early warning are carried out on collected vibration monitoring data, and the vibration monitoring data are stored in the server. And judging whether to switch a WIA-PA or 4G network mode to carry out vibration monitoring or not. The gateway of the data communication layer is used for connecting the physical acquisition layer and the upper control layer and uploading vibration monitoring data to a server and an upper computer; and vibration monitoring equipment of the physical acquisition layer is used for acquiring vibration monitoring data. The method is suitable for fault diagnosis of rotary mechanical equipment, WIA-PA and 4G can make up each other technically, and the method is simpler and easier to use in application.

Description

technical field [0001] The invention relates to the technical field of vibration monitoring, in particular to a vibration monitoring system for large-scale rotary mechanical equipment. Background technique [0002] For large rotating machinery, most of the faults are closely related to mechanical motion or vibration. Vibration monitoring has the characteristics of direct, real-time and wide coverage of fault types. Therefore, vibration monitoring is the core part of various predictive maintenance technologies for rotating machinery, and other predictive maintenance technologies, such as infrared thermal imaging, oil analysis, and electrical diagnosis, are effective supplements to vibration monitoring technologies. [0003] Large-scale rotating machinery has a fault frequency of more than 1Khz. To cover more than 95% of the faults of rotating machinery, an accelerometer with a frequency response range of 10kHz is required, which requires high specifications for sampling rate ...
