[0037] A centralized control system for an air compressor station, comprising:

[0038] The air compressor unit 10, the cooling tower 20 and the cooling water pump 30 are electrically connected to the Internet of Things cloud 40, and the Internet of Things cloud 40 is electrically connected to the full system controller 120. The Internet of Things cloud organizes and stores the data sent from the Internet of Things gateway of each device, helps to complete interactive control between each device, and displays all data to the owner who views it remotely. The full system controller 120 is electrically connected to the control compressor 110, the full system controller 120 is electrically connected to the water pump control box 90, the full system controller 120 is electrically connected to the cooling tower control box 80, and the full system controller 120 is electrically connected to the dryer control box 100.

The key performance indicators of 5G wireless communication technology include peak rate, user experience rate, spectrum efficiency, energy efficiency, connection density, etc. Among them, peak rate refers to the maximum data transmission speed that a device can achieve under specific conditions.

[0045] Working principle:

[0046] In this solution, the IoT gateway in the electrical control cabinet of each device sends the data read in the electrical control cabinet itself and the measurement data of the smart sensor to the IoT cloud. The whole system controller organizes and analyzes the data in the cloud through the gateway, and judges through the automation program in the whole system controller, and issues control instructions to the air compressor units, drying post-processing equipment, cooling water pumps, cooling towers and other equipment in the air compressor station. After receiving the instructions through the gateway, the air compressor units, drying post-processing equipment, cooling water pumps, cooling towers and other equipment begin to complete the actions according to the instructions, and complete the automatic operation in the air compressor station through wireless communication technology, and display the operation process of this air compressor station in real time to the owner.
