Description

Technical Field

[0001] This utility model relates to the field of automatic control system technology, specifically a constant pressure oxygenation control device. Background Technology

[0002] In aquaculture, to ensure oxygen supply and water flow, farmers often manually adjust the air supply valve to control the amount of air flowing into the aquaculture pond, depending on the specific conditions. Fluctuations in air pressure directly affect the airflow and pressure of the Roots blower. Excessive pressure in the pipeline can cause the blower to operate under overload; pressure fluctuations can also cause changes in motor load, affecting motor stability and lifespan. Especially in cases of sudden pressure increases, the motor may be damaged due to overload.

[0003] In different bodies of water used for aquaculture, variations in water level result in different aeration effects. Lower air pressure and deeper water lead to poorer aeration, while shallower water yields better results. However, such adjustments are often made manually based on experience, consuming a significant amount of manpower.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0015] The control panel 1 includes a control switch 11, indicator lights 12, and signal digits 13, which are used to integrate a display interface. The control switch 11 is used to start and stop the control system.

[0016] Processor 2 is connected to control panel 1. Processor 2 uses a commercially available Siemens programmable logic controller (PLC). This signal processor integrates digital inputs and outputs, supports direct connection to process signals, and has functions such as counting and frequency measurement. It can also communicate with other devices through the MPI interface. It also has features such as password protection, diagnostic buffer, and data backup to ensure the security and reliability of the system. The above are existing products on the market, and their connection methods and control methods are existing technologies, which will not be described in detail here.

[0017] Sensor 3 is connected to processor 2. Processor 2 is used to receive and process data from sensor 3. Sensor 3 is a MIK-P300 model, which uses a diffused silicon pressure core as the sensing element for pressure testing. The above are existing products on the market, and their connection and control methods are existing technologies, which will not be described in detail here.

[0018] The signal communicator 4 is connected to the control panel 1 and the processor 2. The processor 2 feeds back the calculation results to the signal communicator 4. The signal communicator 4 is used to receive the calculation data from the processor 2 and to send the pressure adjustment command to the control switch 11.

[0019] Among them, the signal communicator 4 adopts an RS-485 signal communicator, which can maintain the data transmission rate at different distances to meet application requirements. The above are existing products on the market, and their connection methods and control methods are existing technologies, which will not be elaborated here.

[0020] Inverter 5 is connected to signal communicator 4. Signal communicator 4 sends pressure adjustment commands to inverter 5. Inverter 5 is a TD500 vector inverter. Vector control technology is based on DQ axis theory. It achieves precise control of motor speed and torque by accurately adjusting the motor current and voltage. The above are existing products on the market. Their connection methods and control methods are existing technologies and will not be described in detail here.

[0025] In practical implementation, this invention uses a control switch 11 to set the pressure value and sends the data to the processor 2 for calculation. If there is no pressure in the air supply pipe 7, the sensor 3 feeds the data back to the processor 2 for calculation, and then sends the calculation result to the signal communicator 4. The signal communicator 4 sends a start command to the Roots blower 6. If there is pressure in the air supply pipe 7, the sensor 3 feeds the data back to the processor 2 for calculation, and then sends the calculation result to the signal communicator 4. The signal communicator 4 sends a pressure stabilization command to the frequency converter 5, and the frequency converter 5 then guides the motor speed of the Roots blower 6. By using an automatic control device, constant pressure oxygen supply is achieved within the pressure range of the Roots blower 6, thereby extending the service life of the Roots blower 6. This solves the problem of motor overload damage caused by manual control of air flow and the problem of balanced oxygen supply in aquaculture waters of different depths, improving the practicality of the device.
