[0001] This application relates to the field of water pump control technology, and in particular to an outdoor unattended water pump system, control method and storage medium. Background Technology

[0002] Traditional solar water pumps primarily rely on solar panels for energy. However, sunlight exposure is greatly affected by weather conditions, leading to unstable voltage and current output from the solar panels. The traditional solution is to add a battery as a buffer; the solar panels charge the battery first, and then the battery provides a stable power supply to the water pump. However, due to battery life limitations, regular on-site maintenance and battery replacement are necessary. Furthermore, the pump's operation is affected by external factors such as battery status and water level changes, requiring manual adjustment of operating parameters based on these external conditions, resulting in a low level of automation. Summary of the Invention

[0003] Therefore, it is necessary to provide an outdoor unattended water pump system, control method, and storage medium to address the problem of low intelligence level in existing water pump systems.

[0004] In a first aspect, this application provides an outdoor unattended water pump system, comprising:

[0005] The power supply module includes a first power supply group and a second power supply group. The output terminal of the first power supply group is connected to the input terminal of the second power supply group and the first power supply access terminal of the controller module, respectively. The output terminal of the second power supply group is connected to the second power supply access terminal of the controller module. The first power supply group is configured to output a first voltage signal, and the second power supply group is configured to convert the received first voltage signal to obtain a second voltage signal and output it. A wireless communication transceiver module is configured to enable remote data communication between the controller module and an external host computer.

The controller module is configured to select the power supply unit for the water pump motor based on its starting characteristics. The power supply unit includes a first power supply group and a second power supply group. The controller module is also configured to control the operation mode of the water pump motor based on the received current liquid level signal. Furthermore, the controller module is configured to switch the power supply unit based on the received first voltage signal, second voltage signal, and the remaining power of the second power supply group.

[0006] In one embodiment, the first power supply group is a solar panel, which is used to directly convert solar radiation energy into electrical energy through the photoelectric effect.

[0007] In one embodiment, the second power supply group includes a boost energy storage circuit, which includes a first diode, a first resistor, a transformer, a first transistor, and a first capacitor. The anode of the first diode is connected to the positive output terminal of the first power supply group, and the cathode of the first diode is connected to the first resistor and the first terminal of the secondary coil of the transformer. The second terminal of the first resistor is connected to the first terminal of the primary coil of the transformer, and the second terminal of the primary coil of the transformer is connected to the base of the first transistor. The second terminal of the secondary coil of the transformer is connected to the collector of the first transistor and the positive terminal of the first capacitor. The negative output terminal of the first power supply group, the emitter of the first transistor, the negative terminal of the first capacitor, and the ground terminal are all connected together.

[0008] In one embodiment, the first capacitor includes at least one supercapacitor.

[0009] In one embodiment, the power supply module further includes a power supply switching circuit, which includes a second transistor, a second resistor, a third resistor, a fourth resistor, a first MOSFET, and a second MOSFET. The base of the second transistor is connected to the base of the second MOSFET, the first terminal of the fourth resistor, and the first control terminal of the controller module. The collector of the first transistor is connected to the second terminal of the second resistor, the first terminal of the third resistor, and the gate of the first MOSFET. The second terminal of the third resistor, the source of the first MOSFET, and the ground are connected together. The drain of the first MOSFET is connected to the second control terminal of the controller module, and the second control terminal is logically connected to the first power supply access terminal. The second terminal of the fourth resistor is connected to the source and ground of the second MOSFET. The drain of the second MOSFET is connected to the third control terminal of the controller module, and the third control terminal is logically connected to the second power supply access terminal.

[0010] Secondly, the present invention also provides a control method for an outdoor unattended water pump system, applied to the aforementioned outdoor unattended water pump system, the method comprising the following steps:

[0011] The target liquid level and minimum operating liquid level of the water storage container can be remotely set through the wireless communication transceiver module.

[0012] Based on the starting characteristics of the water pump motor, the power supply switching sequence of the first power supply group and the second power supply group is determined to complete the starting of the water pump motor;

[0013] The controller module collects comprehensive parameter characteristics and controls the operation mode of the water pump motor and switches the power supply unit according to the comprehensive parameter characteristics. The comprehensive parameter characteristics include a first voltage signal, a second voltage signal, the remaining power of the second power supply group, and the current liquid level signal. The operation mode of the water pump motor includes start-stop control, high-power operation, and low-power operation.

[0014] In one embodiment, the specific steps of determining the power supply switching sequence of the first power supply group and the second power supply group based on the starting characteristics of the water pump motor, and completing the starting of the water pump motor, include:

[0015] During the startup phase, the controller module cuts off the power supply channel between the first power supply group and the water pump motor, and connects the power supply channel between the second power supply group and the water pump motor, so that the second power supply group provides short-term high-power stable power supply.

[0016] During the stable operation phase after startup, the controller module cuts off the power supply channel between the second power supply group and the water pump motor, and connects the power supply channel between the first power supply group and the water pump motor.

[0017] In one embodiment, the controller module, based on the collected comprehensive parameter characteristics, controls the operation mode of the water pump motor and switches the power supply unit. The specific steps include:

[0018] The sensor module acquires the current liquid level signal of the water storage container and compares it with the minimum operating liquid level. If the current liquid level signal meets the minimum operating liquid level, the water pump motor is allowed to run; if the current liquid level signal does not meet the minimum operating liquid level, the water pump motor stops running.

[0019] Under the conditions that the water pump motor is operating, the current liquid level signal is compared with the target liquid level. If the difference between the current liquid level signal and the target liquid level is greater than or equal to a preset liquid level difference threshold, the water pump motor is controlled to operate at high power. If the difference between the current liquid level signal and the target liquid level is less than the preset liquid level difference threshold, the water pump motor is controlled to operate at low power.

[0020] Under the condition of high-power operation of the water pump motor, the controller module switches the power supply main body of the water pump motor according to the first voltage signal, the second voltage signal and the remaining power of the second power supply group.

[0021] In one embodiment, under the condition of high-power operation of the water pump motor, the controller module switches the power supply of the water pump motor according to the first voltage signal and the second voltage signal. Specific steps include:

[0022] The first voltage signal is compared with a preset minimum high-power operating voltage. If the first voltage signal is greater than or equal to the minimum high-power operating voltage, the power supply entity is the first power supply group, and the first power supply group outputs the first voltage signal to the water pump motor through the controller module. If the first voltage signal is less than the minimum high-power operating voltage, the second voltage signal is compared with the minimum high-power operating voltage. If the second voltage signal is greater than or equal to the minimum high-power operating voltage, the power supply entity is the second power supply group, and the second power supply group outputs the second voltage signal to the water pump motor through the controller module. If the second voltage signal is less than the minimum high-power operating voltage, the power supply entity is either the first power supply group or the second power supply group, and the water pump motor operates at low power.

[0023] Thirdly, embodiments of the present invention also provide a computer-readable storage medium storing a computer program that can be executed by a processor to implement the outdoor unattended water pump system control method described above.

[0024] One of the above technical solutions has the following advantages and beneficial effects:

[0025] In various embodiments of the aforementioned unattended outdoor water pump system, a power supply module, a wireless communication transceiver module, a sensor module, a water pump motor, and a controller module are included. The power supply module comprises a first power supply group and a second power supply group. The first power supply group can directly or indirectly convert solar radiation energy into electrical energy through the photoelectric effect or photochemical effect. The second power supply group includes a boost energy storage circuit, which can store and boost the electrical energy generated by the first power supply group. Since the boost energy storage circuit includes at least one supercapacitor, the number of charge-discharge cycles of a supercapacitor is much greater than that of a traditional battery. Therefore, water pump systems powered by batteries do not require frequent maintenance and battery replacement. However, the energy density of a supercapacitor is lower than that of a battery, and it cannot maintain high power output for a long time. The water pump motor requires a short period of high power output during the startup phase, but the power required for stable operation is lower than the startup power. Therefore, when the water pump motor starts, the controller module first switches to the second power supply group for power. The first voltage signal output by the first power supply group is boosted by the second power supply group and provides the power required by the water pump motor. After the motor starts successfully and enters a stable operating state, the controller module then switches the power supply of the water pump motor back to the first power supply group.

[0026] Furthermore, the current liquid level signal of the water storage container is acquired through the sensor module. The current liquid level signal is compared with the minimum operating liquid level remotely preset by the user through the wireless communication transceiver module to determine the start and stop of the water pump motor. Moreover, under the condition that the water pump motor can operate, the controller module controls the operating status and operating power of the water pump motor through the current liquid level signal, the first voltage signal and the second voltage signal. Under the premise of stable system operation, the current liquid level of the water storage container is quickly brought up to the target liquid level, and the current status information of the system is uploaded to the user through the wireless communication transceiver. There is no need to manually set the operating parameters of the water pump motor at the water pump system site, thus achieving the purpose of unattended operation. Attached Figure Description

[0041] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application. Example 1

[0042] like Figure 1 As shown in the figure, this embodiment provides an outdoor unattended water pump system, including:

[0043] The power supply module includes a first power supply group 11 and a second power supply group 12. The output terminal of the first power supply group 11 is connected to the input terminal of the second power supply group 12 and the first power supply access terminal of the controller module 50, respectively. The output terminal of the second power supply group 12 is connected to the second power supply access terminal of the controller module 50. The first power supply group 11 is configured to output a first voltage signal, and the second power supply group 12 is configured to convert the received first voltage signal to obtain a second voltage signal and output it. A wireless communication transceiver module 20 is configured to enable remote data communication between the controller module 50 and an external host computer. A sensor module 30 is configured to... The system detects the current liquid level in the water storage container and outputs the current liquid level signal to the controller module 50; a water pump motor 40; the controller module 50 is connected to the power supply module, the wireless communication transceiver module 20, the sensor module 30, and the water pump motor 40. The controller module 50 is configured to select the power supply body for the water pump motor 40 based on the starting characteristics of the water pump motor 40; the power supply body includes a first power supply group 11 and a second power supply group 12; the controller module 50 is also configured to control the operation mode of the water pump motor based on the received current liquid level signal; the controller module 50 is also configured to switch the power supply body based on the received first voltage signal, second voltage signal, and the remaining power of the second power supply group 12.

[0044] During the start-up phase of the water pump motor 40, the second power supply group 12 performs voltage boosting processing on the first voltage signal transmitted by the first power supply group 11 to obtain a second voltage signal.

[0045] In the aforementioned unattended outdoor water pump system, the sensor module 30 acquires the current liquid level signal of the water storage container. The current liquid level signal is compared with the minimum operating liquid level remotely preset by the user via the wireless communication transceiver module 20 to determine the start / stop of the water pump motor 40. Furthermore, under the condition that the water pump motor 40 can operate, the controller module 50 controls the operating status and power of the water pump motor 40 through the current liquid level signal, the first voltage signal, and the second voltage signal. Under the premise of stable system operation, the current liquid level in the water storage container quickly reaches the target liquid level, and the system's current status information is uploaded to the user via the wireless communication transceiver. This eliminates the need to manually set the operating parameters of the water pump motor 40 at the water pump system site, achieving the goal of unattended operation.

[0046] In addition to the features of the above embodiments, this embodiment further specifies that: the first power supply group 11 is a solar panel, which is used to directly convert solar radiation energy into electrical energy through the photoelectric effect.

[0047] like Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the second power supply group 12 includes a boost energy storage circuit, the boost energy storage circuit includes a first diode D1, a first resistor R1, a transformer T1, a first transistor Q1 and a first capacitor C1, the anode of the first diode D1 is connected to the positive output terminal of the first power supply group 11, the cathode of the first diode D1 is connected to the first resistor R1 and the first end of the secondary coil of the transformer T1, the second end of the first resistor R1 is connected to the first end of the primary coil of the transformer T1, the second end of the primary coil of the transformer T1 is connected to the base of the first transistor Q1, the second end of the secondary coil of the transformer T1 is connected to the collector of the first transistor Q1 and the anode of the first capacitor C1, and the negative output terminal of the first power supply group 11, the emitter of the first transistor Q1, the cathode of the first capacitor C1 and the ground are connected together.

[0048] In addition to the features of the above embodiments, this embodiment further specifies that: the first capacitor C1 includes at least one supercapacitor.

[0049] The aforementioned outdoor unattended water pump system further specifies that the boost energy storage circuit includes at least one supercapacitor. Since the number of charge-discharge cycles of a supercapacitor is much greater than that of a traditional battery, it does not require the frequent maintenance and battery replacement of a battery-powered water pump system, thereby reducing the number of maintenance cycles and costs of the water pump system.

[0050] It should be noted that because supercapacitors have a lower energy density than batteries, they cannot maintain high power output for extended periods. However, the water pump motor 40 requires a short period of high power output during startup, while the power required for stable operation is lower than the startup power. Therefore, during startup, the controller module 50 switches to the second power supply group 12 for the water pump motor 40. The first voltage signal output from the first power supply group 11 is boosted by the second power supply group 12 and then provides the power required by the water pump motor 40. After successful startup and stable operation, the controller module 50 switches the power supply of the water pump motor 40 back to the first power supply group 11.

[0051] like Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the power supply module also includes a power supply switching circuit, which includes a second transistor Q2, a second resistor R2, a third resistor R3, a fourth resistor R4, a first MOSFET M1, and a second MOSFET M2. The base of the second transistor Q2 is connected to the base of the second MOSFET M2, the first end of the fourth resistor R4, and the first control terminal of the controller module 50. The collector of the first transistor Q2 is connected to the second end of the second resistor R2, the first end of the third resistor R3, and the gate of the first MOSFET M1. The second end of the third resistor R3, the source of the first MOSFET M1, and the ground are connected together. The drain of the first MOSFET M1 is connected to the second control terminal of the controller module 50, and the second control terminal is logically connected to the first power supply access terminal. The second end of the fourth resistor R4 is connected to the source and ground of the second MOSFET M2. The drain of the second MOSFET M2 is connected to the third control terminal of the controller module 50, and the third control terminal is logically connected to the second power supply access terminal.

[0052] The aforementioned outdoor unattended water pump system further defines the power supply module as including a power supply switching circuit and its specific structure. Through this structure, when the water pump motor 40 is in the startup phase, when the controller module 50 outputs a low-level signal to the base of the second transistor Q2, the second transistor Q2 and the second MOSFET M2 are cut off, the first MOSFET M1 is turned on, the second control terminal of the controller module 50 is logically connected to the first power supply access terminal in a conducting state, and the first power supply group 11 outputs a first voltage signal to power the water pump motor 40. When the water pump motor 40 has completed its startup and is running smoothly, the controller module 50 outputs a high-level information to the first control terminal, the second transistor Q2 and the second MOSFET M2 are turned on, the first MOSFET M1 is cut off, the third control terminal of the controller module 50 is logically connected to the second power supply access terminal in a conducting state, the second control terminal of the controller module 50 is logically connected to the first power supply access terminal in a cut-off state, and the second voltage signal output by the second power supply group 12 powers the water pump motor 40. Example 2

[0053] like Figure 4 As shown, this embodiment also provides a control method for an outdoor unattended water pump system, applied to the aforementioned outdoor unattended water pump system, including the following steps:

[0054] Step S10: Remotely set the target liquid level and minimum operating liquid level of the water storage container via the wireless communication transceiver module 20;

[0055] Step S20: Based on the starting characteristics of the water pump motor 40, determine the power supply switching sequence of the first power supply group 11 and the second power supply group 12 to complete the starting of the water pump motor 40.

[0056] Step S30: Collect comprehensive parameter features. The controller module 50 controls the operation mode of the water pump motor 40 and switches the power supply unit according to the comprehensive parameter features. The comprehensive parameter features include first voltage information, second voltage information, remaining power of the second power supply group 12, and current liquid level signal. The operation mode of the water pump motor 40 includes start-stop control, high power operation, and low power operation.

[0057] The aforementioned outdoor unattended water pump system control method acquires the current liquid level signal of the water storage container through the sensor module 30. It compares the current liquid level signal with the minimum operating liquid level remotely preset by the user through the wireless communication transceiver module 20 to determine the start and stop of the water pump motor 40. Furthermore, under the condition that the water pump motor 40 can operate, the controller module 50 controls the operating status and operating power of the water pump motor 40 through the current liquid level signal, the first voltage signal, and the second voltage signal. Under the premise of stable system operation, the current liquid level of the water storage container is quickly brought up to the target liquid level, and the current status information of the system is uploaded to the user through the wireless communication transceiver. There is no need to manually set the operating parameters of the water pump motor 40 at the water pump system site, thus achieving the purpose of unattended operation.

[0058] like Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further defines the following specific steps for determining the power supply switching sequence of the first power supply group 11 and the second power supply group 12 based on the starting characteristics of the water pump motor 40, and completing the starting of the water pump motor 40:

[0059] Step S11: During the startup phase, the controller module 50 cuts off the power supply channel between the first power supply group 11 and the water pump motor 40, and connects the power supply channel between the second power supply group 12 and the water pump motor 40, so that the second power supply group 12 provides short-term high-power stable power supply.

[0060] Step S12: During the stable operation phase after startup, the controller module 50 cuts off the power supply channel between the second power supply group 12 and the water pump motor 40, and connects the power supply channel between the first power supply group 11 and the water pump motor 40.

[0061] Specifically, during the startup phase of the water pump motor, the first control terminal of the controller module 50 outputs a low-level signal to the base of the second transistor Q2. The second transistor Q2 and the second MOSFET M2 are cut off, while the first MOSFET M1 is turned on. The second control terminal of the controller module 50 is logically connected to the first power supply access terminal in a conducting state, and the first power supply group 11 outputs a first voltage signal to power the water pump motor 40. When the water pump motor 40 has started and is running smoothly, the controller module 50 outputs a high-level signal to the first control terminal. The second transistor Q2 and the second MOSFET M2 are turned on, while the first MOSFET M1 is cut off. The third control terminal of the controller module 50 is logically connected to the second power supply access terminal in a conducting state, while the second control terminal of the controller module 50 is logically connected to the first power supply access terminal in a cut-off state. The second voltage signal output by the second power supply group 12 powers the water pump motor 40.

[0062] like Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies: collecting comprehensive parameter features, and the controller module 50 controlling the operation mode of the water pump motor 40 and switching the power supply unit according to the comprehensive parameter features, the specific steps of which include:

[0063] Step S21: The current liquid level signal of the water storage container is obtained through the sensor module 30 and compared with the minimum operating liquid level. If the current liquid level signal meets the minimum operating liquid level, the water pump motor 40 is allowed to run; if the current liquid level signal does not meet the minimum operating liquid level, the water pump motor 40 stops running.

[0064] Step S22: Under the condition that the water pump motor 40 is in operation, the current liquid level signal is compared with the target liquid level. If the difference between the current liquid level signal and the target liquid level is greater than or equal to the preset liquid level difference threshold, the water pump motor 40 is controlled to run at high power. If the difference between the current liquid level signal and the target liquid level is less than the preset liquid level difference threshold, the water pump motor 40 is controlled to run at low power.

[0065] Step S23: Under the condition that the water pump motor 40 is operating at high power, the controller module 50 switches the power supply main body of the water pump motor 40 according to the first voltage signal, the second voltage signal and the remaining power of the second power supply group 12.

[0066] In addition to the features of the above embodiments, this embodiment further specifies that: under the condition of high-power operation of the water pump motor 40, the controller module 50 switches the power supply of the water pump motor 40 according to the first voltage signal and the second voltage signal. The specific steps include:

[0067] The first voltage signal is compared with the preset minimum high-power operating voltage. If the first voltage signal is greater than or equal to the minimum high-power operating voltage, the main power supply is the first power supply group 11, and the first power supply group 11 outputs the first voltage signal to the water pump motor through the controller module 50. If the first voltage signal is less than the minimum high-power operating voltage, the second voltage signal is compared with the minimum high-power operating voltage. If the second voltage signal is greater than or equal to the minimum high-power operating voltage, the main power supply is the second power supply group 12, and the second power supply group 12 outputs the second voltage signal to the water pump motor through the controller module 50. If the second voltage signal is less than the minimum high-power operating voltage, the main power supply is either the first power supply group 11 or the second power supply group 12, and the water pump motor 40 operates at low power.
