An air compressor performance identification and group preference joint control system and method

Abstract

The invention discloses an air compressor performance identification and group preference joint control system and method, which uses multiple sensors to test the vibration signal, current signal, temperature signal, and acoustic emission signal of each air compressor in the group, and adopts multi-transmitter Sensitive information fusion technology fuses the vibration signal, current signal, temperature signal and acoustic emission signal during the operation of the air compressor to realize the effective identification of the current performance of each air compressor, and according to the optimal performance of each air compressor Inferior, determine the preference sequence and running time of each air compressor to ensure the balanced adjustment of the performance of each air compressor in the air compressor group, and avoid the serious performance of the air compressor caused by the long-term operation of a single air compressor Decrease, the service life is severely attenuated, thus greatly improving the working efficiency of the air compressor group and the service life of each air compressor.

Description

technical field [0001] The invention relates to the field of air compressor performance identification and linkage control, in particular to an air compressor performance identification and group preference linkage control system and method based on multi-sensor information fusion. Background technique [0002] Air compressor is a kind of equipment used to compress gas, which is widely used in various fields of industrial production, especially in the field of mining. Air compressor is an important device to provide gas source for various pneumatic equipment in the mining process. Mine air compressors usually appear in groups, that is, multiple air compressors form an air compressor group, and each air compressor in the group delivers compressed gas to the main pipe through its own input pipeline. Due to the great difference in the air consumption at different times during the mining process, the number of air compressors operating in the group also needs to be adjusted acco...

Problems solved by technology

[0005] Although the above two patents have realized the linkage control of air compressors to a certain extent, they did not take into account the different running time and starting frequency of each air compressor in the air compressor group in the control process. The impact of performance can easily lead to accelerated aging of some air compressors due to fatigue service, while the performance of other air compressors cannot be fully utilized due to the small number of starts and short running time, resulting in serious waste of resources. , it is urgent to study a method that can balance the performance of each air compressor, realize the balanced service of each air compressor in the air compressor group, ensure the maximum performance of each air compressor, and effectively extend the service life of each air compressor service life
