Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. 1# air compressor, 2# air compressor, 3, switch, 4, main coordinated system, 5, master control pressure point, 6, 1# air compressor panel, 7, 2# air compressor panel.
The specific implementation mode is as follows:
example 1:
the utility model provides an air compressor machine is whole to coordinate control system which constitutes and includes: 1# air compressor machine 1 and 2# air compressor machine 2, 1# air compressor machine with 2# air compressor machine be connected with switch 3 respectively, switch and main coordinated system 4 be connected, main coordinated system be connected with master control pressure point 5, 1# air compressor machine be connected with 1# air compressor machine panel 6, 2# air compressor machine be connected with 2# air compressor machine panel 7, 1# air compressor machine with 2# air compressor machine' S control PLC adopt siemens S71200 series control ware and IO module, wherein S71200 expands the RS485 interface and carries out MODBUSRTU communication with the air compressor machine controller through the MODBUS communication card.
Example 2:
