[0017] Figure 2 This is a schematic diagram of the monitoring module structure of the air compressor control system. Detailed Implementation

[0018] Please see Figure 1-2 This utility model provides an air compressor control system, including: a controller, an air compressor module, a monitoring module, and an early warning module, wherein the controller is connected to the air compressor module, the monitoring module, and the early warning module respectively;

[0019] The air compressor module is sequentially connected to an air delivery module and an equipment module. The air compressor module transmits the compressed air it generates to the equipment module through the air delivery module to provide driving force to the equipment module. The air delivery module is also connected in parallel with the equipment module to a compensation module. The compensation module is used to compensate for the compressed air delivered by the air delivery module according to the compressed air pressure range required by the equipment module, so as to ensure stable air supply and enable the equipment module to operate stably and continuously.

[0020] The monitoring module is used to monitor the working status of the air compressor module, equipment module, gas transmission module and compensation module in real time, and feed the monitored data back to the controller, which then makes targeted adjustments to each module. At the same time, the controller controls the early warning module to issue an early warning based on the abnormal status of the feedback monitoring data.

[0021] It should be explained that the air volume information required by each pneumatic device in the device module is pre-recorded in the controller. The monitoring module monitors the access volume of the devices and feeds it back to the controller.

[0022] Preferably, the air compressor module is further equipped with a cooling module, which includes a cooling fan and a cooling tower, to cool down the air compressor by means of air cooling and water cooling respectively, so as to avoid the air compressor from continuously overheating and affecting its working efficiency.

[0023] Furthermore, a drying module is provided between the air supply module and the equipment module. The drying module is used to dry the compressed air output by the air supply module. The compensation module is connected between the air supply module and the air compressor module.

[0024] Furthermore, the drying module includes several drying devices connected in parallel, and the input and output ends of each drying device are respectively connected to the air compressor module and the equipment module through the air supply module.

[0025] Among them, several drying devices set in parallel are used to split and dry the compressed air in the gas transmission main, thereby improving the drying efficiency and effect of the drying equipment.

[0026] Specifically, the drying equipment includes a refrigerated dryer or an adsorption dryer, which further removes residual water vapor in the compressed air to prevent water vapor from affecting the performance of the pneumatic equipment.

[0027] Furthermore, the gas delivery module includes: a main gas delivery pipe and a branch gas delivery pipe. The main gas delivery pipe is used to connect the air compressor module and the drying module, as well as the drying module and the equipment module. The compensation module is connected to the main gas delivery pipe through the branch gas delivery pipe. Both the main gas delivery pipe and the branch gas delivery pipe are equipped with flow control valves.

[0028] Furthermore, the compensation module includes a compensation tank and a pressure relief tank, both of which are connected to the main gas supply pipe via the gas supply branch pipe. The compensation tank is pre-filled with high-pressure compressed air, and each gas supply branch pipe is equipped with an intelligent pressure controller, which is used to control the opening and closing of the flow control valve.

[0029] It should be explained that when the monitoring module detects a shortage of compressed air in the gas delivery module (the compressed air pressure in the pipe drops below the preset threshold for the air pressure required by the currently connected start-up equipment), the monitoring module feeds back the abnormal information to the controller, which then controls the compensation module to take action. Specifically, the intelligent pressure controller on the compensation tank side controls the flow control valve on that side of the gas delivery branch pipe to open, allowing compressed air to be injected into the main gas delivery pipe through the compensation tank to replenish pressure and ensure the stable operation of the equipment module. At the same time, the controller controls the air compressor module to operate, gradually increasing the output power of the air compressor to improve the compressed air shortage state in the gas delivery module, and gradually reducing the amount of compressed air injected into the main gas delivery pipe by the compensation tank until the flow control valve closes and there is no compressed air compensation, at which point the intelligent pressure controller stops working.

[0030] When the monitoring module detects an interference imbalance of compressed air in the gas delivery module (the compressed air pressure in the pipe rises to exceed the preset threshold for the air pressure requirement of the currently connected start-up equipment), the monitoring module feeds back the abnormal information to the controller, which then controls the compensation module to take action. Specifically, the intelligent pressure controller on the pressure relief tank side controls the flow control valve on the gas delivery branch pipe on that side to gradually discharge the excess compressed gas in the main gas delivery pipe into the pressure relief tank, ensuring the stable operation of the equipment module. At the same time, the controller controls the air compressor module to gradually reduce the output power of the air compressor, improve the interference imbalance of compressed air in the gas delivery module, and gradually reduce the pressure relief at the flow control valve until the flow control valve is closed and there is no pressure relief, at which point the intelligent pressure controller stops working.

[0031] Furthermore, the monitoring module includes a wireless transmission unit and several acquisition units, which are respectively installed at the air compressor module, air delivery module, compensation module, drying module and equipment module, and are used to collect the operating status parameters of the air compressor module, air delivery module, compensation module, drying module and equipment module. The wireless transmission unit is used to feed back the collected parameters to the controller.

[0032] It should be explained that the acquisition unit includes at least a pressure sensor, a temperature sensor, and a current sensor. The pressure sensor monitors the air pressure at the output end of each air compressor, inside the main air supply pipe, inside the compensation tank, and inside the pressure relief tank in real time. This facilitates real-time control of the amount of compressed air in the system, enabling better matching with the compressed gas demand of the equipment modules and ensuring stable, efficient, and continuous operation of the equipment. The temperature sensor monitors the motor temperature of the air compressor to prevent overheating. The current sensor monitors in real time whether each pneumatic device is connected, ensuring that the air pressure in the system always matches the air pressure required by the pneumatic devices.

[0033] Furthermore, the air compressor module includes several air compressor devices, with the air outlet of each air compressor device connected in parallel to the air inlet of the air delivery module, thereby increasing the upper limit of the matching of the air compressor control system with the devices within the module.

[0034] In practice, the monitoring module monitors the pneumatic equipment connected to the equipment module and transmits the equipment information to the controller. The controller then controls the air compressor module to start and output an appropriate amount of compressed air. The compressed air is delivered to the drying module via the air delivery module for drying. Finally, the air delivery module delivers the dried compressed air to the equipment module to provide driving force for the pneumatic equipment. During this process, the monitoring module monitors the compressed air pressure in real time. When an abnormal pressure occurs, the compensation module compensates for the transmitted compressed air, ensuring that the transmitted compressed air matches the amount required by the equipment module, thus guaranteeing stable, continuous, and efficient operation of the pneumatic equipment.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
