Self-inspection method of air compressor with pressure start-up based on industrial big data and artificial intelligence

Abstract

The invention relates to the technical fields of artificial intelligence and air compressors, in particular to a self-inspection method for starting an air compressor under pressure based on industrial big data and artificial intelligence. The method includes: obtaining the joint similarity of any two air compressor start-up processes, clustering the air compressors to obtain several clusters; merging the clusters whose opening angle difference of the anti-surge valve is less than the preset opening angle difference threshold; twinning After the network is pre-trained, the feature descriptors of each air compressor are obtained; continue to train the twin network, and determine the maximum Estimate the opening angle by likelihood; adjust the anti-surge valve opening angle, and try to start the air compressor under pressure. The invention can accurately determine the opening range and extreme value of the anti-surge valve for successful start-up of the air compressor under pressure according to the maximum likelihood estimation opening angle while protecting the user's industrial big data, so as to ensure that the air compressor can be safely operated under pressure. Start to increase the mean time between failures of the air compressor.

Description

technical field [0001] The invention relates to the technical fields of artificial intelligence and air compressors, in particular to a self-inspection method for starting an air compressor under pressure based on industrial big data and artificial intelligence. Background technique [0002] Air compressors are widely used in petroleum, metallurgy, chemical and other industrial fields. With the rapid development of science and technology, air compressor units tend to be larger and more complex. Due to the increasingly complex operating conditions of the air compressor unit, the balance pressure of the air compressor unit at start-up is no longer a single situation, and more stringent requirements are put forward for the driving equipment and start-up scheme of the air compressor unit. Take a large-scale ethane refrigeration air compressor driven by a motor as an example. Since the process gas is actually at the dew point temperature, affected by the ambient temperature, the ...

AI Technical Summary

Problems solved by technology

In a large-scale industrial process, if professional maintenance personnel are required to participate in the pressurized start-up every time the air compressor is started, and the anti-surge valve is continuously fine-tuned to achieve a smooth start, the efficiency will be greatly reduced, and the time required for manual presence will be greatly reduced. and commissioning time can cause multiple economic losses in modern production
