[0002] Aerators are essential oxygenation equipment for fish farming. Intelligent aerators use electronic technology and 4G wireless transmission to monitor the working status, operating voltage, current, and power of the aerator in real time, and promptly judge abnormalities such as power failure, phase loss, overcurrent, and undervoltage of the aerator, and automatically cut off the power supply of the aerator in time to avoid burning the machine. The aerator can be automatically turned on and off at a fixed time, and the power consumption of the aerator can be counted in real time to achieve the dual purposes of oxygenation and energy saving. The data of the intelligent aerator is transmitted online in real time through 4G wireless signals. The mobile phone can remotely control the switch of the aerator, and the timed automatic opening and closing of the equipment can be set in different time periods. The operating voltage and current of each device can be monitored in real time, and the operating faults such as power failure, overvoltage, undervoltage, phase loss, overcurrent, low current, abnormal equipment shutdown, overload shutdown, etc. are real-time alarms, and users are notified by phone in real time.

Similar control functions are separated from the aerator, and some control parameters are sometimes not matched with the aerator.

Long-term operation will cause the temperature inside the equipment to rise, up to 70°C or more, affecting the service life of the equipment; long-term high-temperature operation will cause the aging of the wires and easily cause electric shock and leakage. The life of ordinary relays is generally 10,000 to 20,000 times, and the temperature rise will cause the life to be halved;

[0027] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application. The illustrations only show the components related to the present application rather than being drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0028] The following is combined with Figure 1-4 The specific implementation methods of this application are further described.

[0029] Example:

[0030] The present application embodiment discloses an intelligent oxygenator with intelligent control and alarm, referring to Figure 1As shown, it includes a controller 1 and an aeration pump (external device), and the aeration pump specifically uses a three-phase motor in circuit control. The aeration pump is powered by a three-phase power supply and is controlled by the controller 1 on the line between the three-phase power supply and the aeration pump. The controller 1 includes a current sampling module 2, a voltage sampling module 3, an ACDC power supply module 4, a DCDC module 5, and an MCU processor module 6. The current sampling module 2 is used to collect three-phase line current data and feed it back to the MCU processor module 6, the voltage sampling module 3 is used to collect three-phase line voltage data and feed it back to the MCU processor module 6, the ACDC power supply module 4 is used to provide the standard power supply required for the operation of each module, and the controller 1 also includes a DCDC module 5, a 4G module 7, a LoRa module 8 and a magnetic latching relay module 9.

[0031] The ACDC power module 4 converts and outputs a 12V voltage output, and then the 12V power is used as the power input of the DCDC module 5, which can output a 3.3V voltage and a 4.2V voltage. The 3.3V power supply is provided to the MCU processor module 6 for power supply, and the 4.2V power supply can be provided to the 4G module 7 for power supply. The LoRa module 8 is the wireless antenna part, which can realize remote communication by connecting with the 4G module 7.

[0032] The DCDC module 5 is connected to the output end of the ACDC power module 4, and is used to provide working power to the MCU processor module 6 and the 4G module 7. The MCU processor module 6, the 4G module 7, and the LoRa module 8 are connected in sequence for wireless data transmission and reception.

[0033] In this solution, a magnetic latching relay module 9 is used to connect to the MCU processor module 6 and is used as an output end to connect to control the oxygen pump.

[0034] The incoming line adopts a three-phase four-wire system, supports single-phase / three-phase input, and is integrated with the oxygen pump. The wiring is simple and the response is sensitive. It can sample and feedback the voltage and current of the input power supply. During the operation of the equipment, the MCU processor module 6 can send the sampled voltage, current, and alarm data to Alibaba Cloud (platform) through the 4G module 7, and then push it to the enterprise server and display it on the mobile phone applet; the user can open and close the oxygen pump through the magnetic latching relay module 9. The relay is controlled by a magnetic latching relay. The advantage of the magnetic latching relay is that it controls the action of the relay through a pulse signal. After the action is completed, this state is maintained by the magnetic material. The long-term working temperature of the relay will not cause temperature rise due to the coil, ensuring that the equipment as a whole operates at normal temperature; the mechanical life of the magnetic latching relay can reach millions of times. It adopts 4G module 7 and LoRa module 8 for connection, which is used for wireless data transmission and reception, convenient data upload, and remote control. Either the 4G module or the LoRa module can be used. In a specific example, such as Figure 1As shown in FIG. , it is a schematic diagram of a practical 4G module to realize wireless data transmission. Figure 4 In the figure, the use of LoRa module to realize data transmission and reception is shown.

[0035] Specifically, the MCU processor module 6 is also connected to the data storage module 10 for storing an alarm signal, which is generated by the MCU processor module 6 after receiving the current sampling data and the voltage sampling data. In one example, the alarm signal is a current overload or a voltage overload.

[0036] exist Figure 3 In the embodiment, the magnetic latching relay module 9 includes three circuit modules 91, each circuit module 91 controls one phase of the three-phase circuits A, B, and C, and each circuit module 91 includes a current limiting resistor 1, a current limiting resistor 2, a driving chip, and a magnetic latching relay. In this example, the current limiting resistor 1 can be R43, the current limiting resistor 2 can be R40, and the driving chip can be U8.

[0037] One pin of the MCU processor module 6 is connected to the A input pin of the driver chip through a current limiting resistor 1, and the second pin of the MCU processor module 6 is connected to the B input pin of the driver chip through a current limiting resistor 2. The A output pin and the B output pin of the driver chip are respectively connected to the coil part of the magnetic holding relay. The switch part of the magnetic holding relay controls one phase circuit in the three-phase circuit. The model of the driver chip is GM8023B.

[0038] The signal terminals DAT6 and DAT5 are connected to the pins of the microprocessor module. The same is true for other circuit modules 91.

[0039] exist Figure 2 The power failure detection module 11 is also included. The power failure detection module 11 is connected to the output end of the ACDC power supply module 4 to detect its voltage output and output a feedback signal to the MCU processor module 6.

[0040] Specifically, the power-off detection module 11 includes resistor R79, resistor R86, resistor R81, diode D3, capacitor C62, and transistor Q6; the voltage input terminal VCCIN is connected to one end of the resistor R79 and the anode of the diode D3, the cathode of the diode D3 is connected to the positive electrode of the capacitor C62 and the voltage source VCC12V, the negative electrode of the capacitor C62 is grounded, the other end of the resistor R79 is connected to one end of the resistor R86 and the base of the transistor Q6, the collector of the transistor Q6 is connected to one end of the resistor R81 and the output power-off feedback signal PWR-CK, the other end of the resistor R86 and the emitter of the transistor Q6 are grounded, and the other end of the resistor R81 is connected to the voltage source VCC3V3. The capacitor C62 is an electrolytic capacitor with a withstand voltage of 50V. Connected in the above manner, in a specific example, for the detection voltage VCCIN, when VCCIN is 12V under the input of the power supply VCCIN, the transistor Q6 is turned on. The feedback signal PWR-CK is low.

[0041] If VCCIN loses power, transistor Q6 is turned off. At this time, due to the existence of voltage source VCC3V3, the feedback signal PWR-CK is at a high level.

[0042] It can be seen that it is only necessary to determine whether the feedback signal PWR-CK received by the microcontroller pin is at a high level to determine whether there is a power outage. In the case of a power outage, since the capacitor C62 has been charged in advance, the capacitor C62 can provide a short-term storage during the power outage to wait for the power to be restored during this storage period. Therefore, on the right side of the diode D3, the voltage source VCC12, that is, the 12V voltage is relatively stable and reliable.

[0043] refer to Figure 5 As shown, it also includes a stainless steel water-cooled motor, a junction box, a reduction box, a float, a bend pipe, a flange, an impeller, and a pressure plate. The above-mentioned controller is an intelligent controller, which is fixedly installed on the top of the stainless steel water-cooled motor through a junction box. The stainless steel water-cooled motor is fixedly connected to the middle of the float through a bend pipe in the circumferential direction. The float is provided with a semicircular groove for the end of the bend pipe to be embedded. The pressure plate is fixed on the semicircular groove by screws. The rotating shaft of the stainless steel water-cooled motor is connected to the reduction box, and the output shaft of the reduction box is connected to the impeller through a flange. In this embodiment, three bend pipes are used to support and fix the stainless steel water-cooled motor, so that it is in the center of the float when working.

[0044] The top of the motor is equipped with an intelligent controller, which can monitor the working voltage and current of the motor in real time, and monitor whether the three-phase power supply is missing phase, fault, etc., to prevent the motor from accidentally burning out. The gears in the reduction box are made of titanium alloy steel, and the tooth surface is carbon-ammonia co-penetrated, which greatly prolongs the service life. The stainless steel elbow plays a supporting role. The structural design of the elbow is more reliable and durable, especially suitable for marine aquaculture. The whole machine floats on the water surface, and the top of the motor is equipped with an intelligent controller. When working, the impeller rotates under the drive of the motor. The rotating impeller stirs the water body, forming water splashes and waves, expanding the contact surface between water and air, dissolving oxygen into the water, and allowing harmful gases contained in the water to escape into the atmosphere, improving the water quality of the fish pond.

[0045] The above embodiments are only illustrative of the principles and effects of the present application, and are not intended to limit the present application. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application shall be included in the protection scope of the present application.
