Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to a control circuit for an aquaculture feeding machine. Background Technology

[0002] With the continuous advancement of science and technology and the increasing emphasis on the natural ecological environment, smart aquaculture has become the future path of modern fisheries. It involves digital transformation and innovation based on traditional fisheries and uses high-end technology to improve aquaculture efficiency.

[0003] Feeding is the biggest cost and the most labor-intensive part of aquaculture. Improper feeding can also affect fish growth and pollute water sources, which is inconsistent with the concept of green development. With the continuous expansion of aquaculture scale, traditional manual feeding methods can no longer meet the needs of modern large-scale aquaculture, resulting in problems such as high labor intensity, low feeding efficiency, and uneven feeding.

[0004] Currently, most feeders on the market can only feed the entire amount at a time or stop manually, making it difficult to achieve precise quantitative feeding and meet the needs of small, frequent, and precise feeding in animal husbandry. The components of feeders are relatively complex and prone to malfunction, such as the vibrator of a vibratory feeder failing to vibrate or dispense feed, or the pipes of a pneumatic feeder becoming clogged. This can also lead to untimely feeding and affect the growth of farmed animals. Furthermore, the decision-making models lack universality and are difficult to apply to all farmed species and environments. Utility Model Content

[0050] As described in the background section, existing feeding methods cannot meet the needs of all farmed species and farming environments, thus affecting the growth of farmed animals.

[0051] To address the aforementioned technical problems, this utility model provides a control circuit for an aquaculture feeder. The power supply unit provides a first power supply voltage to the controller and a second power supply to the communication component. On one hand, the controller can determine whether to generate a first control signal to drive the feeder to feed based on a first detection signal received from the material detection circuit, thereby achieving automatic feeding. On the other hand, based on a second detection signal transmitted by the metering circuit, the controller can also generate a second control signal to stop the feeder from feeding, thereby achieving quantitative feeding. Furthermore, the communication component can transmit signals and data from the feeding process, enabling remote control.

[0052] In other words, the control circuit of the aquaculture feeder provided in this application can not only accurately feed the aquatic products at precise times and in precise quantities, but also remotely control the feeder and monitor its status in real time, reducing labor costs, saving aquaculture costs, and realizing intelligent aquaculture.

[0053] To enable those skilled in the art to better understand and implement this utility model, the following detailed description of the specific scheme, principle, advantages and effects of this utility model is provided with reference to the accompanying drawings and specific embodiments.

[0054] In this utility model, see Figure 1 The schematic diagram shown below illustrates the structure of the control circuit of an aquaculture feeder in an embodiment of this utility model. Figure 1 As shown, the control circuit 100 of the aquaculture feeder may include:

[0055] Material detection circuit 110 that obtains the current remaining feed status and generates the first detection signal;

[0056] The controller 130, which is electrically connected to the material detection circuit 110, generates a first control signal to the feeder (not shown) in response to the first detection signal when it determines that the remaining amount of feed is lower than a first preset threshold, thereby driving the feeder to feed the feeder; and generates a second control signal to the feeder in response to the second detection signal when it determines that the weight of the feed being fed meets a second preset threshold, thereby driving the feeder to stop feeding the feeder.

[0057] A metering circuit 120 is installed on the feeding path and electrically connected to the controller 130. The metering circuit 120 is used to determine the weight of the fed feed and generate the second detection signal.

[0058] A communication component 140 electrically connected to the controller 130, the communication component 140 interacting with the controller 130 to transmit data corresponding to the first detection signal and the second detection signal;

[0059] A power supply unit 150 is electrically connected to the controller 130 and the communication component 140 respectively. The power supply unit 150 is used to convert the initial voltage, provide a first power supply voltage to the controller 130, and provide a second power supply voltage to the communication component 140.

[0060] Combination Figure 1 Briefly describe the working principle of the control circuit 100 of the aquaculture feeder in this embodiment of the present invention:

[0061] The power supply unit 150 is capable of converting the initial voltage and providing a first power supply voltage to the controller 130 and a second power supply voltage to the communication component 140, so that the controller 130 and the communication component 140 can be in an operational state.

[0062] On the one hand, the material detection circuit 110 can obtain the current remaining status of the feed (e.g., parameters such as the height and mass of the remaining feed, where the height of the remaining feed can characterize the quality of the feed), thereby generating a first detection signal characterizing whether the current feed is sufficient.

[0063] The controller 130 can determine the relationship between the remaining amount of feed corresponding to the first detection signal and a first preset threshold based on the first detection signal. Specifically, when it is determined that the remaining amount of feed is lower than the first preset threshold, the controller 130 can output a first control signal to the feeder, which can then perform a feeding operation to achieve automatic feeding.

[0064] Meanwhile, the metering circuit 120 installed on the feeding path can monitor the weight of the feed that has been fed in real time and generate a second detection signal to the controller 130.

[0065] The controller 130 can determine the relationship between the amount of feed to be fed corresponding to the second detection signal and a second preset threshold based on the second detection signal. Specifically, when it is determined that the remaining amount of feed meets the second preset threshold (for example, the remaining amount of feed is equal to the second preset threshold), the controller 130 can output a second control signal to the feeder, and the feeder can stop feeding operations to achieve precise feeding.

[0066] The controller 130 can output the acquired signal and this parameter to a server (such as an APP in a mobile phone) through the communication component 140 to realize remote operation.

[0067] In short, it can provide precise, timed, and quantitative feeding, and also allows for remote control of the feeder and real-time monitoring of its status, reducing labor costs, saving on breeding costs, and achieving intelligent breeding.

[0068] In some embodiments, see reference Figure 2The diagram shows a controller structure. The controller 130 may include a microprocessor (MCU). This gives the controller 130 high performance, high flexibility, and abundant peripheral resources, enabling it to process multiple signals simultaneously and be suitable for various scenarios.

[0069] More specifically, the controller 130 can be an STM32F103C8T6.

[0070] The process by which controller 130 generates a control signal based on the detected signal and a preset threshold is a conventional solution. The focus of this invention is the data interaction process between controller 130 and the material detection circuit 110 and metering circuit 120. In other words, by pre-configuring the execution logic of controller 130, it can naturally output a control signal when executing this solution. Furthermore, for more details regarding controller 130, please refer to existing examples. Figure 2 Only the circuit structure of the MCU with model number STM32F103C8T6 is shown.

[0071] In some other embodiments, the controller may also be a general-purpose processor, such as one or more of a central processing unit (CPU), an application-specific integrated circuit (ASIC), and a programmable logic device (PLD).

[0072] In some embodiments, combined with Figure 1 See Figure 3 The schematic diagram shown below illustrates the structure of a metering circuit according to an embodiment of the present invention. The metering circuit 120 may include:

[0073] A strain gauge (not shown) is installed on the weighing platform, which generates a measurement signal proportional to the weight of the feed being fed. The weighing platform is located on the feeding path. An interface branch P1 is electrically connected to the strain gauge. A switch branch P2 has a first state and a second state. When in the first state, the interface branch P1 provides the working voltage to the strain gauge. When in the second state, the power supply path is disconnected. An analog-to-digital converter chip P3 is electrically connected to the switch branch P2, the interface branch P1, and the controller 130, respectively. By changing the drive signal output to the switch branch P2, the switch branch P2 can be in either the first state or the second state. When the switch branch P2 is in the first state, the measurement signal is acquired through the interface branch P1, and the measurement signal is converted into a digital signal and output to the controller 130.

[0074] Using the metering circuit 120 with the above structure, the quality of the feed that has been fed can be accurately determined.

[0075] In some embodiments, the switching branch P2 includes: a first resistor R1, a second resistor R2, a first transistor Q1, a third resistor R3, a fourth resistor R4, a first capacitor C1, a second capacitor C2, a third capacitor C3, and a fourth capacitor C4. The first terminal of the first resistor R1 is connected to the first terminal of the first capacitor C1, the interface branch P1 (e.g., port 1 of the interface branch P1), the first terminal of the first transistor Q1, and the AVDD port of the analog-to-digital converter chip P3, respectively. The second terminal of the first resistor R1 is connected to the first terminal of the second resistor R2 and the VFB port of the analog-to-digital converter chip P3, respectively. The second resistor R2 and the second terminal of the first capacitor C1 are grounded. The control terminal of the first transistor Q1 is connected to the BASE port of the analog-to-digital converter chip P3. The second terminal of the first transistor Q1 is connected to the VSUP port of the analog-to-digital converter chip P2 and the first terminal of the fourth capacitor C4, and is input with a first voltage VCC1; the first terminal of the second capacitor C2 is grounded, and the second terminal of the second capacitor C2 is connected to the VBG port of the analog-to-digital converter chip P3; the first terminals of the third resistor R3 and the fourth resistor R4 are connected to the interface circuit P1 (for example, the third resistor R3 is connected to port 3 of the interface branch P1, and the fourth resistor R4 is connected to port 4 of the interface branch P1); the second terminal of the third resistor R3 is coupled to the first terminal of the third capacitor C3 and the INNA port of the analog-to-digital converter chip P3, respectively; the second terminal of the fourth resistor R4 is coupled to the second terminal of the third capacitor C3 and the INPA port of the analog-to-digital converter chip P4, respectively.

[0076] The working principle of the switch branch P2 is as follows: When the sampling process is executed, the voltage of the control terminal of the first transistor Q1 is actively pulled low through the BASE port, so that the first transistor Q1 is turned on. In this way, the working voltage E is provided to the strain gauge through port 1 of the interface branch P1.

[0077] At this point, the strain gauge is working. When the strain gauge is under stress, its resistance changes, causing the bridge circuit to lose balance and generating a very small millivolt-level analog differential voltage signal (i.e., S+ and S-) at the output of the bridge circuit. The magnitude of this voltage is proportional to the weight of the material.

[0078] The analog-to-digital converter chip P3 can receive the differential voltage signal, and then convert the differential voltage signal into an analog-to-digital signal, outputting the digital signal to the controller 130 through the DOUT port.

[0079] After sampling is complete, the BASE port is released. After voltage division by the first resistor R1 and the second resistor R2, the first transistor Q4 port is driven, thereby disconnecting the power supply path between the first voltage VCC1 and the strain gauge.

[0080] It should be noted that, firstly, the structure of the strain gauge can refer to existing examples, and this application does not limit the structure of the strain gauge; secondly, the interface branch P1 also has port 4, which is grounded; thirdly, the analog-to-digital converter chip P3 can be of model HX711. For more information on the HX711 model analog-to-digital converter chip P3, please refer to existing examples.

[0081] In some embodiments, the material detection circuit 110 may be an infrared beam sensor, which communicates with the controller 130 via a physical connector.

[0082] The design and principle of the infrared beam sensor are as follows: A transmitter, which may include an infrared light-emitting diode (LED), is placed on one side of the infrared beam sensor. The transmitter is typically connected to the positive terminal of a power supply and a ground wire. A receiver is placed on the other side of the infrared beam sensor, and the receiver is strictly aligned with the transmitter. The receiver may include a phototransistor or a photodiode (infrared LED).

[0083] When there is no material obstructing the path of the infrared beam (Clear Beam), the light emitted by the transmitter shines on the receiver almost unimpeded, i.e., in a material-free state.

[0084] When material passes through the infrared beam (Blocked Beam), the material will block part or all of the infrared light, greatly reducing the light intensity reaching the receiver, thus indicating that there is material present.

[0085] The strength of the current or voltage signal generated by the receiver is proportional to the intensity of the received light. The receiver circuit (usually composed of a comparator) sets a threshold voltage. When the received light intensity is strong enough (above the threshold), the output is in one state; when the received light intensity is below the threshold (e.g., the light beam is blocked by material), the output flips to another state to achieve feed detection.

[0086] See Figure 4 The diagram shown is a structural schematic of a physical connector, as follows: Figure 4 As shown, the physical connector includes connector P4 (e.g., the connector shown in Figure 2*2, having pins 1, 2, 3 and 4), and a fifth resistor R5 and a sixth resistor R6 disposed between connector P4 and the controller 130, and the connector P4 is powered by a second voltage VCC2.

[0087] In other words, the first detection signal is transmitted as an electrical signal between the material detection circuit 110 and the controller 130 through the connector P4, which has 4 pins.

[0088] In some embodiments, interference from other factors may occur, causing the controller 130 to malfunction.

[0089] Therefore, the control circuit may further include a trigger circuit disposed between the material detection circuit and the controller. By setting the trigger circuit, precise feed monitoring can be achieved.

[0090] See Figure 5 The schematic diagram shown below illustrates the structure of a trigger circuit in one embodiment of this utility model. Figure 5 As shown, the trigger circuit may include: a second transistor Q2, a third transistor Q3, a fourth transistor Q4, a seventh resistor R7, an eighth resistor R8, a ninth resistor R9, a tenth resistor R10, an eleventh resistor R11, and a fifth capacitor C5.

[0091] In this circuit, the control terminal of the second transistor Q2 is connected to the material detection circuit 110 and the first terminal of the seventh resistor R7, respectively. The first terminal of the second transistor Q2 receives the third voltage VCC3, and the third terminal of the second transistor Q2 is coupled to the first terminal of the eighth resistor R8. The second terminal of the seventh resistor R7 is grounded. The second terminal of the eighth resistor R8 is connected to the control terminals of the third transistor Q3 and the fourth transistor Q4, and the first terminal of the ninth resistor R9, respectively. The first terminal of the third transistor Q3 is coupled to the controller 130 through the tenth resistor R10, and the second terminal of the third transistor Q3 is coupled to the first terminal of the fourth transistor Q4, the first terminal of the fifth capacitor C5, and the first terminal of the eleventh resistor R11, respectively. The fifth capacitor C5, the ninth resistor R9, the tenth resistor R11, and the second terminal of the fourth transistor Q4 are grounded.

[0092] The trigger circuit works as follows: When the control terminal of the second transistor Q2 receives the first detection signal from the material detection circuit 110, the control terminal of the second transistor Q2 changes from low to high, and the second transistor Q2 changes from cutoff to conduction. The potential of the eighth resistor R8 changes from low to high, causing the control terminal of the third transistor Q3 to reach a high potential, and the third transistor Q3 conducts. The controller 130 charges the fifth capacitor C5. Since the voltage of the fifth capacitor C5 cannot change abruptly, the voltage at the port connected to the tenth resistor R10 is pulled low, triggering the controller 130 to indicate the presence of the first detection signal from the material detection circuit 110.

[0093] As the capacitor C5 charges, its voltage changes from low to high. When the voltage across C5 reaches a certain value, the third transistor Q3 turns off, stopping the charging of C5 and halting the receiving process. At this point, capacitor C14 discharges through the eleventh resistor Q11.

[0094] In some embodiments, the power supply unit 150 can supply power to the controller 130 and the communication component 140 simultaneously. Since the operating voltages of the controller 130 and the communication component 140 are usually different, the initial voltage can be converted to obtain supply voltages with different amplitudes.

Figure 7As shown, the second voltage conversion module includes: an eighth capacitor C8, a second voltage conversion chip U2, a ninth capacitor C9, and a tenth capacitor C10. The first terminal of the eighth capacitor C8 is connected to the input terminals Vin of the first voltage conversion module U1 and the second voltage conversion chip U2, respectively. The second terminal of the eighth capacitor C8 is connected to the adjustment terminal Adj of the second voltage conversion chip U2, the second terminals of the ninth capacitor C9 and the tenth capacitor C10, and is grounded. The output terminal Vo of the second voltage conversion chip U2 is connected to the first terminals of the ninth capacitor C9 and the tenth capacitor C10.

[0100] Among them, the second voltage conversion chip U2 is a low-dropout linear regulator, model LM1117.

[0101] See Figure 8 The schematic diagram shown in this application illustrates the structure of a third voltage conversion module in an embodiment of the present application. Figure 8 As shown, the third voltage conversion module may include: a third voltage conversion chip U3, a fourteenth resistor R14, a fifteenth resistor R15, an eleventh capacitor C11, a twelfth capacitor C12, a thirteenth capacitor C13, a fourteenth capacitor C14, a fifteenth capacitor C15, a sixteenth capacitor C16, and a Zener diode C17.

[0102] The third voltage conversion chip U3 is connected to the first voltage conversion module U1. The output terminal OUT of the third voltage conversion chip U3 is connected to the first terminals of the eleventh capacitor C11, the twelfth capacitor C12, the thirteenth capacitor C13, the fourteenth capacitor C14, the fifteenth capacitor C15, and the sixteenth capacitor C16, and the second terminal of the Zener diode D1.

[0103] Among them, the third voltage conversion chip U3 is a high-performance linear regulator, model SPX29302T5-L / TR.

[0104] In some embodiments, in order to better control the feeding process of the feeder, the feeder is also equipped with a fan, a vibrator and a slinger; it also includes: a fan, a vibrator and a slinger.

[0105] The feeder is the starting point and control core of the entire system. Its main function is to stably and controllably extract and release materials from the silo or storage bin at a preset rate (by volume or weight). Feeders can be of various types, such as screw feeders, vibrating feeders, belt feeders, rotary valves, etc.

[0106] Vibrators serve to prevent clogging and promote flow, and are typically installed in the receiving / transition sections of silos, hoppers, or feeders. When stored material exhibits "bridging" or "rat hole" phenomena in the silo, the feeder may not receive a stable or sufficient supply of material. The vibration energy generated by the vibrator acts on the silo or hopper walls, breaking up the bridging structure of the material, loosening clumps, and restoring and maintaining smooth flow.

[0107] The vibrator may include one of the following: a pneumatic piston vibrator, a pneumatic turbine / high-frequency vibrator, an electric vibrator, and an electromagnetic vibrator.

[0108] The blower serves as a pneumatic conveyor or environmental control device, and the feeder can deliver accurately measured feed into the airflow generated by the blower.

[0109] The blower may include one or more of centrifugal blowers and Roots blowers.

[0110] The slinger is usually located downstream of the feeder. It receives a fixed amount of material from the feeder and uses the centrifugal force of high-speed rotation (or in combination with other designs) to evenly throw, disperse, or spread the material to a specific area or surface.

[0111] The slinger can include one of the following: a center-driven rotary slinger, an under-disc driven rotary slinger, or a throwing arm dispenser.

[0112] It should be noted that the feeding machine, fan, vibrator and slinger are all mature components in the existing solution.

[0113] Accordingly, see next. Figure 1 The control circuit further includes a fan control unit 160, a vibrator control unit 170, and a disc control unit 180 connected to the controller 130. The controller 130 supplies power to the fan through the fan control unit 160; the controller 130 supplies power to the vibrator through the vibrator control unit 170; and the controller 130 supplies power to the disc through the disc control unit 180.

[0114] In some embodiments, the fan control unit 160, the vibrator control unit 170, and the swivel disc control unit 180 adopt the same structure.

[0115] See Figure 9 A schematic diagram of the structure of the control unit is shown below. Figure 7 As shown, each component includes: a sixteenth resistor R16, a seventeenth resistor R17, a fifth transistor Q5, a first diode D2, a solenoid valve FM, and a switch K1. The first terminal of the sixteenth resistor R16 is coupled to the controller, and the second terminal of the sixteenth resistor R16 is connected to the first terminal of the seventeenth resistor R17 and the control terminal of the fifth transistor Q5, respectively. The first terminal of the fifth transistor Q5 is connected to the first diode D2 and the first terminal of the solenoid valve FM, and the fifth transistor Q5 is connected to the second terminal of the seventeenth resistor R17 and grounded. The second terminal of the first diode D2 is connected to the second terminal of the solenoid valve FM and receives a fourth voltage VCC7. The solenoid valve FM and the switch K1 function as follows:

[0116] The control unit works as follows: upon receiving a signal from controller 130, the voltage divider effect of resistors R16 and R17 causes transistor Q5 to conduct, thus forming a path of voltage VCC7-FM-Q5-ground. At this time, solenoid valve FM activates, causing switch K1 to close, providing power to the fan, vibrator, and swivel plate.

[0117] When the fifth transistor Q5 is turned off, the solenoid valve FM is enabled, and the switch K1 is turned off.

[0118] In some embodiments, in order for the feeder to deliver the required weight, the feeder may operate for a longer period of time.

[0119] Based on this, the control circuit may further include a delay circuit coupled between the feeder and the controller.

[0120] See Figure 10 The schematic diagram shown in this embodiment of the present invention illustrates a delay circuit. The delay circuit may include: an eighteenth resistor R18, a nineteenth resistor R19, a twentieth resistor R20, a twenty-first resistor R21, a twenty-second resistor R22, a twenty-third resistor R23, a sixth transistor Q6, a seventh transistor Q7, an eighth transistor Q8, and a seventeenth capacitor C17.

[0121] The first end of the eighteenth resistor R18 is connected to the controller 130, and the first end of the eighteenth resistor R18 is coupled to the control terminal of the sixth transistor Q6; the first end of the sixth transistor Q6 is coupled to the first end of the nineteenth resistor R19, and the second end of the sixth transistor Q6 is coupled to the control terminal of the seventh transistor Q7; the first end of the seventh transistor Q7 is coupled to the first ends of the twentieth resistor R20, the seventeenth capacitor C17, and the twenty-first resistor R21 respectively; the first ends of the nineteenth resistor R19, the twentieth resistor R20, the seventeenth capacitor C17, and the second end of the eighth transistor Q8 are coupled and input with the fifth voltage VCC8; the control terminal of the eighth transistor Q8 is coupled to the second end of the twenty-first resistor R21, and the first end of the eighth transistor Q8 is coupled to the first ends of the twenty-second resistor R22 and the twenty-third resistor R23 respectively; the second end of the twenty-second resistor R22 is grounded; the second end of the twenty-third resistor R23 is coupled to the feeder.

[0122] The working principle of the delay circuit is as follows:

[0123] When the controller 130 outputs the first control signal, the sixth transistor Q6 turns on, which in turn causes the seventh transistor Q7 to saturate and turn on, and the potential at the first terminal of the seventh transistor Q7 drops to a low level. The third transistor then turns on, thus enabling it to output a signal to the feeder.

[0124] While the seventh transistor Q7 is saturated and conducting, the first terminal of the seventh transistor Q7 rapidly charges the seventeenth capacitor C17 to near the fifth voltage VCC8. However, after the current disappears instantaneously, the sixth transistor Q6 and the seventh transistor Q7 are turned off.

[0125] Because the seventeenth capacitor C17 is connected to the twenty-first resistor R21 and the eighth transistor Q8, the eighth transistor Q8 remains on for a certain period of time. Furthermore, due to the large time constant of the discharge circuit formed by the twentyth resistor R20, the charge stored in the seventeenth capacitor C17 discharges relatively slowly.

[0126] In some embodiments, to facilitate real-time modification of parameters for the feeder, this application also provides a button display unit, which is used to provide a local setting interface and local display.

[0127] See Figure 11 The schematic diagram shown below illustrates the structure of a button display unit in this utility model. Figure 11 As shown, the button display unit may include:

[0130] Among them, such as Figure 11 As shown, one of the button circuits includes: a button K21, a twenty-fourth resistor R241, and an eighteenth capacitor C181. The first terminal of the button outputs a display signal (e.g., connected to the PB10 port of the controller 130) and is coupled to the first terminal of the twenty-fourth resistor R241 and the eighteenth capacitor C181, respectively. The second terminal of the button K21 is connected to the second terminal of the eighteenth capacitor C181 and inputs a sixth voltage VCC9 (e.g., VCC3.3V). The second terminal of the twenty-fourth resistor R241 is grounded.

[0131] Specifically, different functions can be achieved by triggering different buttons K21.

[0132] For the structure of other button circuits, please refer to [reference needed]. Figure 11 , not described.

[0133] A variable resistor R25 is used, with the first terminal of the variable resistor R25 receiving the sixth voltage VCC9, the second terminal of the variable resistor R25 being grounded, and the third terminal of the variable resistor R25 being coupled to the VO port of the display chip.

[0134] The regulating circuit, connected to the controller 130 (e.g., connected to port PB7 of the controller 130), includes: a 26th resistor R26, a 27th resistor R27, a 28th resistor R28, a 9th transistor Q9, a 10th transistor M1, and a 19th capacitor C19. The first terminal of the 26th resistor R26 is connected to the controller 130; the second terminal of the 26th resistor R26 is connected to the first terminal of the 27th resistor R27 and the control terminal of the 9th transistor Q9, respectively. The first terminal of the 9th transistor Q9 is connected to the control terminal of the 10th transistor M1 and the first terminal of the 28th resistor R28, respectively. The second terminal of the 9th transistor Q9 is coupled to the second terminal of the 27th resistor R27 and the first terminal of the 19th capacitor C19, and grounded. The first terminal of the 10th transistor M1 is connected to the second terminal of the 28th resistor R28 and receives the 6th voltage; the second terminal of the 10th transistor M1 is connected to the second terminal of the 19th capacitor C19.

The 4G module embeds multiple network protocol stacks, including but not limited to TCP / IP, HTTP, and MQTT. The integration of these protocols allows the connection board to adapt to different network environments and application requirements. Users can flexibly configure the server connection parameters for the 4G module using built-in AT commands to enable the 4G module to connect to a designated server.

[0142] In some embodiments, the 4G module has a radio frequency interface, through which the 4G module is connected to the antenna circuit. The connection between the 4G module and the antenna circuit can be found in existing examples.
