[0021] To facilitate understanding of the present invention, the present invention is described in more detail below with reference to the accompanying drawings and specific embodiments. The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the disclosure of the present invention.

[0022] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art in the technical field of this utility model. The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit the utility model. The term "and / or" as used in this specification includes any and all combinations of one or more of the relevant listed items.

[0023] Figure 1 The diagram shows a composition diagram of an embodiment of a feeding control circuit for aquaculture according to the present invention. The feeding control circuit for aquaculture includes a processor 1, a motor control valve module 3, a control valve terminal 4 and a power supply module 2.

[0024] Processor 1 is used to control the drive motors. There can be multiple drive motors. In this embodiment, there are six drive motors, namely a travel drive motor, a lifting drive motor, a stirring drive motor, a vibration drive motor, a large belt drive motor, and a small belt drive motor. These are respectively used to drive the movement, lifting, stirring, and vibration of the material distribution vehicle, as well as the movement of the small and large belts on the material distribution vehicle. Processor 1 is electrically connected to motor control valve module 3, power supply module 2, and control valve terminal 4. Power supply module 2 is also electrically connected to motor control valve module 3 and control valve terminal 4. Power supply module 2 is used to supply power to processor 1, motor control valve module 3, and control valve terminal 4. Motor control valve module 3 is used to receive control signals from processor 1 to control the on and off of the drive motors. For example, the control valve in motor control valve module 3 corresponding to the large belt drive motor can be closed to turn the large belt drive motor on; when the control valve is open, the large belt drive motor can be turned off. The control valve terminal 4 is used to receive the control signal of the processor 1 to control the operation of the drive motor, for example: the large belt motor rotates forward, the large belt motor rotates reversely. In this embodiment, the large belt rotates forward for feeding, and the large belt rotates reversely for discharging.

[0025] Here, the power module 2 primarily performs voltage conversion and voltage regulation. The processor 1 is the central processor in the material distribution vehicle control circuit. A single-chip microcomputer is typically used for this purpose due to its compact size and low cost. The processor 1 primarily collaborates with the human-machine interface (HMI) to set various parameters, display operating status, and control various actions performed by the motor-controlled valve module 3 and the control valve terminal 4. A HMI refers to an input / output interface, such as a touch screen, display, or keypad. A touch screen can be both an input and output component. The motor-controlled valve module 3 and the control valve terminal 4 primarily control the drive motors under the control of the processor 1. Because the on / off durations of these drive motors, as well as the timing relationships between the drive motors, vary, the HMI is required to configure the parameters of each motor-controlled valve module 3 and the control valve terminal 4. For example, to set the main belt feed time to 12 seconds, the motor-controlled valve module 3 must control the main belt drive motor for 12 seconds, and the control valve terminal 4 must control the main belt forward rotation for 12 seconds. Accordingly, the processor 1 can flexibly and accurately control the drive motor through the motor control valve module 3 and the control valve terminal 4.

[0026] Accordingly, the present invention provides a material distribution control circuit for aquaculture, comprising a processor 1, a motor control valve module 3, a control valve terminal 4, and a power module 2. The circuit structure is very simple and the implementation cost is low. The motor control valve module 3 controls the on / off of the drive motor; the control valve terminal 4 controls the operation of the drive motor. This allows the material distribution vehicle to travel to any culture bed, ascend or descend to any layer of the culture bed, and then perform actions such as opening the door, pushing out material, vibrating, and stirring. This allows the material distribution vehicle to load and unload material to a specified layer on a specified culture bed, ensuring the automation and precision of the loading and unloading process.

[0027] Combine Figure 2 As shown, in some embodiments, the motor control valve module 3 includes two single-machine control valve branches and three dual-machine control valve branches, the two single-machine control valve branches are respectively a first single-machine control valve branch and a second single-machine control valve branch, the first single-machine control valve branch includes a ninth single-machine intermediate relay coil KM9 and a second single-machine thermal relay QF2 connected in series in sequence, the second single-machine control valve branch includes a tenth single-machine intermediate relay coil KM10 and a third single-machine thermal relay QF3 connected in series in sequence, the ninth single-machine intermediate relay coil KM9 and the tenth single-machine intermediate relay coil KM10 are also electrically connected to the processor 1, respectively, the second single-machine thermal relay QF2 and the third single-machine thermal relay QF3 are electrically connected to the power supply module 2, the single-machine control valve branch is used to control the on and off of a drive motor, for example, in this embodiment, the first single-machine control valve branch controls the on and off of the stirring drive motor.

[0028] The dual-machine control valve branches are respectively the first dual-machine control valve branch, the second dual-machine control valve branch and the third dual-machine control valve branch. In the first dual-machine control valve branch, the first dual-machine intermediate relay normally closed contact KM1 and the seventh dual-machine intermediate relay coil KM7 are connected in series, the second dual-machine intermediate relay normally closed contact KM2 and the eighth dual-machine intermediate relay coil KM8 are connected in series, the first dual-machine intermediate relay normally closed contact KM1 and the second dual-machine intermediate relay normally closed contact KM2 are also electrically connected to the processor 1 respectively, the seventh dual-machine intermediate relay coil KM7 and the eighth dual-machine intermediate relay coil KM8 are electrically connected in parallel to the first dual-machine thermal relay QF1, and the first dual-machine thermal relay QF1 is then electrically connected to the power module 2. The specific connection relationship between the second dual-machine control valve branch and the third dual-machine control valve branch is referenced. Figure 2 As shown, no further details are given here. The dual-machine control valve branch can control the on-off of the two drive motors. For example, in this embodiment, the first dual-machine control valve branch can simultaneously control the on-off of the lifting drive motor and the large belt drive motor.

[0029] Of course, in use, the motor control valve module 3 may include more single-machine control valve branches, fewer or more dual-machine control valve branches, for use in conjunction with controlling more or fewer drive motors, and there is no limitation here.

[0030] Combine Figure 3 As shown, in some embodiments, the control valve terminal 4 is electrically connected to the control valve interface circuit 401, the control valve interface circuit 401 is electrically connected to the processor 1, the control valve terminal 4 includes 38 wiring branches, each wiring branch includes an intermediate relay normally open contact, the intermediate relay normally open contacts of the 38 wiring branches are: KM1-KM38, one end of the intermediate relay normally open contact is electrically connected to the control valve interface circuit 401, and the other end is used to electrically connect to the drive motor, the control valve interface circuit 401 controls the on and off of the wiring branch, and the wiring branch controls the operation of a drive motor by closing the intermediate relay normally open contact.

[0031] In some embodiments, specifically, Figure 3 As shown, the control valve interface circuit 401 includes a resistor R1, a resistor R2, a resistor R3, a light-emitting diode V1, a diode V2, and a one-way thyristor S, wherein a first end of the resistor R1 and a first end of the resistor R2 are electrically connected to an I / O pin of the processor 1, a second end of the resistor R1 is electrically connected to the anode of the light-emitting diode V1, and the cathode of the light-emitting diode V1 is grounded. The light-emitting diode V1 serves as an operating indicator light for indicating power-on operation. The second end of the resistor R2 is electrically connected to the first end of the resistor R3 and the base of the one-way thyristor S, respectively. The second end of the resistor R3 is grounded. The resistors R2 and R3 act as a voltage divider. The emitter (also called the cathode) of the one-way thyristor S is grounded, and the collector (also called the anode) of the one-way thyristor S is electrically connected to the control valve terminal 4. The collector of the one-way thyristor S is connected in series with the positive electrode of a protection diode V2, and the negative electrode of the protection diode V2 is connected to a DC 24V supply.

[0032] Therefore, based on Figure 3 In the control valve interface circuit 401 shown, when the processor 1 outputs a high-voltage control signal (e.g., 5V) through an I / O pin, the light-emitting diode (LED) V1 is illuminated, indicating that the control valve interface circuit 401 is executing a control instruction. Specifically, the high-voltage control signal causes the base and emitter of the one-way thyristor (S) to conduct, thereby lowering the collector voltage. This generates a low voltage at the control valve terminal 4. Based on the control instruction, the normally open contact of the intermediate relay on a branch terminal of the control valve terminal 4 closes, causing the motor to operate. When the processor 1 outputs a low-voltage control signal (e.g., 0V) through an I / O pin, the light-emitting diode (LED) V1 is turned off, indicating that the control valve interface circuit 401 is shut down. Simultaneously, the low-voltage control signal causes the base and emitter of the one-way thyristor (S) to turn off, effectively disconnecting the collector. Therefore, the branch terminal of the control valve terminal 4 is not turned on, and the motor is not driven.

[0033] It can be seen that this circuit composition can not only clearly instruct the wiring branch to perform an action, but also has the advantages of simple structure and low implementation cost, and can realize more control interface circuit layouts within a limited space.

[0034] Combine Figure 4 As shown, in some embodiments, the cloth control circuit for breeding is further provided with a frequency converter 5, and the drive motor includes a first type of drive motor. In this embodiment, the first type of drive motor includes a walking drive motor and a lifting drive motor. The motor pins U, V, W, and E of the frequency converter 5 are electrically connected to the first type of drive motor M, and the control pins FWD, REV, S1, S2, S3, S4, and GND of the frequency converter 5 are electrically connected to the processor 1. The power pins R, S, and T of the frequency converter 5 are electrically connected to the power module 2.

[0035] Here, the frequency converter 5 adopts a V / F control mode. It should be understood that V / F control means ensuring that the output voltage is proportional to the frequency. On the one hand, V / F control can keep the magnetic flux of the first type drive motor M constant, avoiding the occurrence of weak magnetic field and magnetic saturation, which will affect the speed of the first type drive motor M and burn the first type drive motor M. On the other hand, the frequency converter 5 can adjust the speed of the first type drive motor M according to actual needs to adapt it to different workloads. By adjusting the speed of the first type drive motor M, the walking speed and lifting speed can be controlled. Of course, in operation, the frequency converter 5 in vector control mode can also be used, and this is not limited here.

[0036] Combine Figure 5 As shown, in some embodiments, processor 1 is electrically connected to a load cell 6, which is electrically connected to an RS485 interface circuit, which is electrically connected to processor 1. Load cell 6 is used to measure the weight of the material within the fabric conveyor. In this embodiment, the RS485 interface circuit utilizes an eight-pin RS485 level transceiver, the MAX485, which offers high cost-effectiveness and low power consumption.

[0037] Specifically, the MAX485 includes an output pin RO, an output control pin RE, an input pin DI, an input control pin DE, a ground pin GND, a power line pin VCC, RS485 bus pin A, and RS485 bus pin B. The output pin RO, output control pin RE, input pin DI, and input control pin DE are connected to processor 1, the power line pin VCC is connected to 5V, the ground pin GND is connected to ground, and RS485 bus pins A and RS485 bus pins B are connected to load cell 6. The MAX485 can output measurement data from RS485 bus pins A and RS485 bus pins B to processor 1 via output pin RO, facilitating real-time monitoring of the material weight in the distribution vehicle, accurately controlling the amount of material input and output, and achieving scientific farming.

[0038] Combine Figure 6 As shown, in some embodiments, the processor 1 is electrically connected to an encoder 7, and the encoder 7 includes a first output pin A, a second output pin B and a ground pin C. The first output pin A and the second output pin B are respectively electrically connected to two I / O pins of the processor 1, and the ground pin C is directly grounded. The first output pin A is also electrically connected to the resistor R4 and then connected to a 3.3V voltage. The second output pin B is also electrically connected to the resistor R5 and then connected to a 3.3V voltage. The encoder 7 is used to measure the number of revolutions of the first type of drive motor, and output the data to the processor 1 through the first output pin A and the second output pin B, thereby realizing the control of the walking and lifting distance of the cloth vehicle and accurately positioning the position.

[0039] Combine Figure 7 As shown, in some embodiments, the processor 1 is electrically connected to a touch screen 8 and three status indicator lights 9, which respectively indicate a communication status indicator, an operating status indicator, and a fault status indicator. The touch screen 8 communicates with the processor 1 via an SPI interface, wherein the clock pin SCK, input pin MISO, output pin MOSI, chip select pin CS, and interrupt request pin IRQ are connected to the processor 1. The touch screen 8 is used to display the status of various components of the material distribution vehicle. In this embodiment, the touch screen 8 displays the lifting status, vibration status, pallet status, lateral status, large belt status, small belt status, front door status, rear door status, stirring status, and material weight in the vehicle. The touch screen 8 can also be used to control the aforementioned states of the material distribution vehicle and set certain parameters for these states. Through these operations, the culture vehicle can automatically move to a designated location for loading and unloading materials, reducing the workload of the staff.

[0040] In this embodiment, if Figure 7As shown, the status indicator light 9 includes a communication status indicator light V3, an operation status indicator light V4 and a fault status indicator light V5. The communication status indicator light V3, the operation status indicator light V4 and the fault status indicator light V5 are all light-emitting diodes. Among them, the communication status indicator light V3 is also electrically connected to a resistor R7, a resistor R8, a resistor R9 and a transistor Q1. The first end of the resistor R7 and the first end of the resistor R8 are commonly electrically connected to an I / O pin of the processor 1, the second end of the resistor R8 is grounded, the second end of the resistor R7 is electrically connected to the base of the transistor Q1, the emitter of the transistor Q1 is grounded, the collector of the transistor Q1 is electrically connected to the cathode of the communication status indicator light V3, the anode of the communication status indicator light V3 is electrically connected to the first end of the resistor R9, and the second end of the resistor R9 is connected to a 5V voltage. The processor 1 controls whether the communication status indicator light V3 is illuminated.

The circuit structure is very simple and the implementation cost is low. The motor control valve module controls the on and off of the drive motor, and the control valve terminal controls the operation of the drive motor. Based on this, the material distribution vehicle is controlled to move to any culture bed, to be raised or lowered to any layer of the culture bed, and then to perform actions such as opening the door, pushing out the material, vibrating, and stirring. This enables the material distribution vehicle to load and unload material to a specified layer on a specified culture bed, ensuring the automation and precision of the loading and unloading process.
