Multi control method for a plurality of air compressors

Abstract

The present invention relates to an integrated control operation method for multiple air compressors, wherein the method is capable of performing integrated control on the air compressors used in various industrial fields using one integrated controller, and more efficiently operating the air compressors. The present invention relates to the integrated control operation method for the air compressors, wherein the method comprises: a step of forming the air compressors including at least one variable speed drive (VSD) air compressor and normal air compressor; a step of mutually connecting the air compressors and the integrated controller with an RS-485 communication port so that the air compressors and the integrated controller communicate with each other, wherein the integrated controller is made up of air compressor control programs; a step of determining the reference value of working air pressure for a demander, and inputting and storing the reference value in the integrated controller; sequentially stopping the air compressors according to the order of priority, dropping the working air pressure, and recovering the working air pressure to the reference value when the working air pressure for the demander exceeds the reference value; and a step of recovering the working air pressure to the reference value by sequentially operating the stopped air compressors according to the order of priority when the working air pressure for the demander drops below the reference value.

Description

technical field [0001] The present invention relates to an integrated control operation method of multiple air compressors, more particularly to a multiple air compressors used in various industrial sites with an integrated controller integrated control, and can operate more efficiently. Integrated control operation method for compressors. Background technique [0002] When multiple air compressors are connected and used at industrial sites in various fields, each air compressor is manually turned on / off according to the number of uses, etc. Manpower and other inefficiencies. [0003] It is explained as follows. [0004] In general, mechanical regulator air compressors are on / off operated by relay signals. The start of the air compressor is due to the consumption of three-phase high-power electric power, and the reactor and Y-Δ start are carried out (the initial power is turned on with the Y connection, and after about 10 seconds, the connection is changed, the connection...

Problems solved by technology

[0012] Therefore, connecting multiple air compressors, grasping the data related to the driving time, pressure, temperature, and current of the air compressors, and generating a driving signal including the control value of the air compressors, because it is impossible to provide selective individual control or Integrated control technology for more than one air compressor makes it impossible to stably and efficiently control and operate multiple air compressors composed of various air compressors
