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. Multiple types of sensors are adopted to test the vibration signal, current signal, temperature signal and acoustic emission signal of each air compressor in a group; the multi-sensing information fusion technology is adopted to fuse the vibration signal, current signal, temperature signal and acoustic emission signal in the operating process of the air compressor to effectively identity the current performance of each air compressor; and according to the high and low degree of the performance of each air compressor, the start-stop preference sequence and the operating duration of each air compressor, equalizing regulation of the performance of each air compressor in the group is ensured, and the situation that long-term operation of a single air compressor to cause that the performance of the air compressor is seriously lowered and the service life is seriously shortened is avoided, so that the working efficiency of the air compressor group is greatly improved and the service life of each air compressor is greatly prolonged.

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
