Embodiment Construction

[0046] Rotating equipment monitoring system embodiment:

[0047] Such as figure 1 As shown, the rotating equipment monitoring system includes a sensor that collects the vibration signal of the centrifugal pump, an edge computing unit (not shown in the figure) and a cloud server installed inside the sensor. The edge computing unit preprocesses the vibration signal and obtains the characteristic The data is transmitted to the cloud server through the wireless gateway. The cloud server analyzes the received characteristic data to obtain the specific fault diagnosis results of the centrifugal pump, and then transmits the specific fault diagnosis results to the user terminal, and the user can view the centrifugal pump fault diagnosis results on the terminal.

[0048] The preprocessing process of the edge computing unit in this embodiment includes the following steps:

[0049] 1) According to the acquired vibration signal f(t) of the centrifugal pump, such as figure 2 As shown, ...

Abstract

The invention, which belongs to the field of equipment fault monitoring, relates to an edge calculation method for monitoring rotating equipment, a medium and a system. The method comprises the following steps: step one, preprocessing a collected vibration signal of rotating equipment by using an edge computing unit; to be specific, implementing the preprocessing by calculating a pass frequency value of the vibration signal according to the vibration signal, performing frequency domain conversion on the vibration signal, dividing the converted frequency domain vibration signal into a pluralityof narrowband signals, carrying out inverse Fourier transform on each narrowband signal to obtain a time domain signal of each narrowband, calculating a vibration amplitude corresponding to each narrowband signal, and determining whether the pass frequency value and the vibration amplitude of each narrow band exceed standards or not, and generating equipment state information according to determination results; and step two, transmitting characteristic data to a cloud server. According to the invention, the collected vibration waveform data of the rotating equipment are converted into the characteristic data transmitted to the cloud server, so that the cost of network transmission is reduced; and the integrity of transmission information is considered at the same time.

Description

technical field [0001] The invention relates to an edge computing method, medium and system for monitoring rotating equipment, and belongs to the field of equipment fault monitoring. Background technique [0002] With the rapid development of wireless sensor networks and cyber-physical fusion systems, how to more effectively extract real-time feature data of industrial equipment, judge equipment operating status, and avoid fault failures or false positives is the key to the current equipment intelligent diagnosis and cyber-physical fusion systems. an important issue in the field. In the current wireless equipment monitoring system, each wireless vibration sensor network only collects and transmits equipment vibration data in function, and does not have the function of data analysis and processing, nor can it automatically identify equipment failures. [0003] After the traditional sensor nodes collect the equipment vibration information, they need to transmit the complete v...
