Description

Technical Field

[0001] The present invention relates to the field of irrigation technology, and in particular to an irrigation device and system. Background Art

[0002] Traditional irrigation systems (for example, rice field irrigation systems) have a low level of mechanical automation. Water is typically pumped directly into canals, where it flows directly into the irrigated fields. If the water source is far away or the irrigated area is large, fields near the source receive more water, while fields farther from the source receive less. Furthermore, to ensure that each field receives equal water, manual opening and closing of the water inlet is required. When drainage is needed, manual opening of the drain outlet is also required. This not only requires significant labor costs, but also poses a low level of automation. Summary of the Invention

Therefore, it should not be understood as a limitation on the present invention.

[0082] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0083] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0084] Please refer to Figure 1 This embodiment provides an irrigation system 10, which includes a user terminal 200 and at least one irrigation device 100. The user terminal 200 is communicatively connected to each irrigation device 100. The user terminal 200 is used to send a work instruction to each irrigation device 100, and each irrigation device 100 is used to perform an irrigation or drainage operation according to the work instruction.

[0085] In this embodiment, the irrigation system 10 may be, but is not limited to, a rice field irrigation system, a greenhouse vegetable irrigation system, a fish pond irrigation system, etc. For ease of description, this application takes the irrigation system 10 as an example of a rice field irrigation system.

[0086] In this embodiment, the user terminal 200 may be, but is not limited to, a mobile phone, a tablet computer, a laptop computer, a server, or other electronic devices with processing capabilities.

[0087] In this embodiment, different irrigation devices 100 are set in different plots, and each plot includes a water supply channel, an irrigation area, and a drainage channel. That is, different irrigation devices 100 control the irrigation operations of different plots.

[0088] Please refer to Figure 2 , is a schematic diagram of an implementable structure of the irrigation device 100 provided in this embodiment, the irrigation device 100 includes a main control module 110, a water supply control module 120 and an inlet and outlet control module 130, the main control module 110 is electrically connected to the water supply control module 120 and the inlet and outlet control module 130, and the main control module 110 is also in communication with the user terminal 200. Figure 3 As shown, it is a schematic diagram of an implementable application environment of the irrigation device 100 provided in this embodiment, the water supply control module 120 is arranged in the water supply channel, the water inlet and outlet control module 130 is arranged in the irrigation area, the water supply channel is connected to the irrigation area, and the water supply channel is also connected to the river.

[0089] In this embodiment, the main control module 110 is used to receive the work instructions sent by the user terminal 200, and send the work instructions to the water supply control module 120 and the water inlet and drainage control module 130; the water supply control module 120 is used to collect the first water level information of the water supply channel according to the work instructions, and control the water supply of the water supply channel according to the first water level information; the water inlet and drainage control module 130 is used to collect the second water level information of the irrigation area according to the work instructions, and control the irrigation and drainage of the irrigation area according to the second water level information.

[0090] It is understood that the user terminal 200 can send a work instruction to the main control module 110 in response to a user operation, so that the main control module 110 forwards the work instruction to the water supply control module 120 and the inlet and drain control module 130. The water supply control module 120 and the inlet and drain control module 130 will not start working until they receive the work instruction. Similarly, the user terminal 200 can send a stop work instruction to the main control module 110 in response to a user operation, so that the main control module 110 forwards the stop work instruction to the water supply control module 120 and the inlet and drain control module 130. The water supply control module 120 and the inlet and drain control module 130 will stop working after receiving the stop work instruction.

[0091] In this embodiment, the water supply control module 120 is further configured to transmit the first water level information to the main control module 110; the water inlet and outlet control module 130 is further configured to transmit the second water level information to the main control module 110; and the main control module 110 is further configured to transmit the first water level information and the second water level information to the user terminal 200. The user terminal 200 can store and display the first and second water level information obtained, so that the user can view and monitor the irrigation status of the plot in real time.

[0092] Of course, after obtaining the first water level information of the water supply channel and the second water level information of the irrigation area through the user terminal 200, the user can manually operate the user terminal 200 to issue water supply control instructions, irrigation commands, and drainage commands to the main control module 110. The main control module 110 then forwards the water supply control instructions to the water supply control module 120, which controls the water supply of the water supply channel according to the water supply control instructions. The main control module 110 also forwards the irrigation command or drainage command to the inlet and drainage control module 130, which controls the irrigation and drainage of the irrigation area according to the irrigation and drainage commands.

[0093] It is understood that the water supply control module 120 can automatically control the water supply of the water supply channel based on the first water level information, or can control the water supply of the water supply channel based on a water supply control instruction issued by the user. The inlet and outlet control module 130 can automatically control the irrigation and drainage of the irrigation area based on the second water level information, or can control the irrigation and drainage of the irrigation area based on an irrigation control instruction or a drainage control instruction issued by the user.

[0094] like Figure 4 As shown, the main control module 110 includes a main control unit 111, a power carrier unit 112 and a power supply unit 113. The main control unit 111 is communicatively connected to the user terminal 200. The main control unit 111 is electrically connected to the water supply control module 120 and the inlet and outlet control module 130 through the power carrier unit 112. The power supply unit 113 is electrically connected to the main control unit 111, the water supply control module 120 and the inlet and outlet control module 130 through the power carrier unit 112.

[0095] In this embodiment, the main control unit 111 is used to receive working instructions and transmit the working instructions to the power carrier unit 112; the power supply unit 113 is used to provide working power to the power carrier unit 112; the power carrier unit 112 is used to modulate the working instructions with the working power to obtain a modulated signal, and send the modulated signal to the water supply control module 120 and the water inlet and outlet control module 130.

[0096] It can be understood that the main control module 110 is composed of a main control unit 111, a power carrier unit 112 and a power supply unit 113. The main control unit 111, the power carrier unit 112 and the power supply unit 113 can be three independent products or integrated into one product.

[0097] The power supply unit 113 primarily provides power to the entire irrigation device 100. The main control unit 111, the brain of the irrigation device 100, communicates data with the user terminal 200 via wireless communication. It also communicates data with the power carrier unit 112 via wired communication. The power carrier unit 112 primarily integrates operating instructions with operating power, enabling it to simultaneously supply power to the water supply control module 120 and the inlet and outlet control module 130 while also exchanging communication data.

[0098] It can be understood that the power carrier unit 112 can be electrically connected to both the water supply control module 120 and the water inlet and drain control module 130 via a non-polarity two-wire low-voltage power carrier bus. While the power carrier unit 112 supplies power to the water supply control module 120 and the water inlet and drain control module 130 via the non-polarity two-wire low-voltage power carrier bus, it can also communicate with the water supply control module 120 and the water inlet and drain control module 130. Because both communication and power supply are achieved via the non-polarity two-wire low-voltage power carrier bus, the water supply control module 120 and the water inlet and drain control module 130 can be connected to the non-polarity two-wire low-voltage power carrier bus regardless of their polarity. Therefore, wiring is very convenient; only two buses need to be laid, and the water supply control module 120 and the water inlet and drain control module 130 can be connected to the non-polarity two-wire low-voltage power carrier bus regardless of their polarity, which is very friendly to plot wiring.

[0099] like Figure 5 As shown, the main control unit 111 includes a first controller 1111, a first communication subunit 1112 and a second communication subunit 1113. The first controller 1111 is communicatively connected to the user terminal 200 through the first communication subunit 1112, and the first controller 1111 is electrically connected to the power carrier unit 112 through the second communication subunit 1113.

[0100] In this embodiment, the first controller 1111 is used to receive the working instruction through the first communication subunit 1112 ; the first controller 1111 is also used to transmit the working instruction to the power carrier unit 112 through the second communication subunit 1113 .

[0101] It is understood that the first communication subunit 1112 can be a wireless communication module such as a 4G module and a WIFI module, and the second communication subunit 1113 can be a 485 communication module. The first controller 1111 can be an integrated circuit chip with signal processing capabilities. The first controller 1111 can be a single-chip microcomputer, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc.

[0102] To identify the land parcel, the main control unit 111 further includes a positioning subunit 1114, which is electrically connected to the first controller 1111. The positioning subunit 1114 is configured to send location information to the first controller 1111; the first controller 1111 is further configured to send the location information to the user terminal 200 via the first communication subunit 1112.

[0103] It is understood that the irrigation device 100 has a built-in positioning subunit 1114 that can achieve precise positioning, and the user terminal 200 can identify the plot based on the different location information fed back by different irrigation devices 100. The positioning subunit 1114 can use a GPS (Global Positioning System) module.

[0104] like Figure 5 As shown, the power carrier unit 112 includes a second controller 1121, a third communication subunit 1122 and a first power carrier subunit 1123. The second controller 1121 is electrically connected to the main control unit 111 through the third communication subunit 1122. The second controller 1121 is electrically connected to the water supply control module 120 and the water inlet and outlet control module 130 through the first power carrier subunit 1123. The second controller 1121 is also electrically connected to the power supply unit 113.

[0105] In this embodiment, the second controller 1121 is used to receive the working instruction through the third communication subunit 1122; the second controller 1121 is also used to modulate the working power provided by the power supply unit 113 with the working instruction through the first power carrier subunit 1123 to obtain a modulated signal.

[0106] It will be appreciated that the second controller 1121 loads the operating instruction onto the operating power to generate a modulated signal, and then transmits the modulated signal to the water supply control module 120 and the drainage control module using the first power carrier subunit 1123. For example, if the operating power provided by the power supply unit 113 is 5V DC, and the operating instruction is a PWM (Pulse Width Modulation) wave, the second controller 1121 can perform pulse width modulation based on the high and low level ratio of the operating instruction using the 5V DC as a reference to generate the modulated signal.

[0107] The third communication subunit 1122 may be a 485 communication module, and the second controller 1121 may be a single-chip microcomputer, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. The first power carrier subunit 1123 may be a power carrier module.

[0108] like Figure 5 As shown, the power supply unit 113 includes a solar charging subunit 1131, an AC / DC conversion subunit 1132, a first voltage conversion subunit 1133 and a battery 1134. The solar charging subunit 1131 is electrically connected to the solar panel 300, and the AC / DC conversion subunit 1132 is electrically connected to the power grid 400. The solar charging subunit 1131 and the AC / DC conversion subunit 1132 are both electrically connected to the battery 1134 and the power carrier unit 112 through the first voltage conversion subunit 1133.

[0109] In this embodiment, the solar charging subunit 1131 is used to convert the first electric energy provided by the solar panel 300 into the second electric energy; the AC / DC conversion subunit 1132 is used to convert the mains power provided by the power grid 400 into the third electric energy; the first voltage conversion subunit 1133 is used to convert the second electric energy and the third electric energy into working electric energy, and transmit the working electric energy to the power carrier unit 112; the first voltage conversion subunit 1133 is further used to convert the second electric energy and the third electric energy into charging electric energy, and transmit the charging electric energy to the battery 1134; the battery 1134 is used to provide working electric energy to the power carrier unit 112 through the first voltage conversion subunit 1133 when the AC / DC conversion subunit 1132 does not provide the second electric energy and the AC / DC conversion subunit 1132 does not provide the third electric energy.

[0110] It is understood that the power supply unit 113 can not only be connected to the power grid 400 and use 220V mains power, but can also be powered by the solar panel 300 when it is inconvenient to run a line to the power grid 400 or when the power grid 400 is out of power. Furthermore, when neither the power grid 400 nor the solar panel 300 can provide power, the irrigation device 100 can be powered by the large-capacity battery 1134. This improves the power supply reliability of the irrigation device 100.

[0111] The AC / DC conversion subunit 1132 is an AC-DC (alternating current-direct current) step-down module, which is used to step down and rectify the 220V mains electricity to obtain a third DC power source. The first voltage conversion subunit 1133 is a DC-DC (direct current-direct current) conversion module, which converts the second power source and the third power source into charging power. The first voltage conversion subunit 1133 can also convert the second power source and the third power source into operating power. The first voltage conversion subunit 1133 can also convert the power source provided by the battery 1134 into operating power.

[0112] like Figure 5 As shown, the power carrier unit 112 also includes a second voltage conversion subunit 1124, and the main control unit 111 also includes a third voltage conversion subunit 1115. The second voltage conversion subunit 1124 is electrically connected to the first voltage conversion subunit 1133, the third voltage conversion subunit 1115, and the second controller 1121. The first voltage conversion subunit 1133 provides operating power to the third voltage conversion subunit 1115 via the second voltage conversion subunit 1124. The third voltage conversion subunit 1115 converts the operating power into the power required for the operation of the first controller 1111. The second voltage conversion subunit 1124 is further configured to convert the operating power into converted operating power and transmit the converted operating power to the second controller 1121. The second controller 1121 is configured to modulate the converted operating power with the operating instruction to obtain a modulated signal.

[0113] Please refer to Figure 6 , which is another feasible structural diagram of the irrigation device 100 provided in this embodiment, the water supply control module 120 includes a first water level detection unit 121, a water pump control unit 122 and a water pump 123, the water supply channel includes a primary water supply channel and a secondary water supply channel, the first water level detection unit 121 is electrically connected to the water pump control unit 122 and the main control module 110, and the water pump control unit 122 is electrically connected to the water pump 123. Please refer to Figure 7 , which is a schematic diagram of another applicable application environment of the irrigation device 100 provided in this embodiment, the first water level detection unit 121 is arranged on the primary water supply channel and the secondary water supply channel, and the water pump 123 is arranged on the primary water supply channel.

[0114] In this embodiment, the first water level information includes primary water level information and secondary water level information; the first water level detection unit 121 is used to collect the primary water level information of the primary water supply channel according to the working instruction, and transmit the primary water level information to the water pump control unit 122; the first water level detection unit 121 is also used to collect the secondary water level information of the secondary water supply channel according to the working instruction, and transmit the secondary water level information to the water pump control unit 122; the water pump control unit 122 is used to control whether the water pump 123 works according to the primary water level information and the secondary water level information, so as to control whether the water in the primary water supply channel is pumped into the secondary water supply channel.

[0115] It can be understood that the first water level detection unit 121 is electrically connected to the first power carrier subunit 1123 and the water pump control unit 122 via a non-polarity two-wire low-voltage power carrier bus. After receiving the modulated signal transmitted by the first power carrier subunit 1123 via the non-polarity two-wire low-voltage power carrier bus, the first water level detection unit 121 parses the modulated signal to obtain a working instruction and also obtains working power from the modulated signal.

[0116] like Figure 8 As shown, the first water level detection unit 121 includes a primary water level sensor 1211, a secondary water level sensor 1212, a third controller 1213 and a second power carrier subunit 1214. The third controller 1213 is electrically connected to the water pump control unit 122 and the main control module 110 through the second power carrier subunit 1214. The primary water level sensor 1211 and the secondary water level sensor 1212 are both electrically connected to the third controller 1213; the primary water level sensor 1211 is arranged in the primary water supply channel, and the secondary water level sensor 1212 is arranged in the secondary water supply channel.

[0117] In this embodiment, the third controller 1213 is used to control the primary water level sensor 1211 to collect primary water level information of the primary water supply channel and obtain primary water level information according to the working instruction; the third controller 1213 is also used to control the secondary water level sensor 1212 to collect secondary water level information of the secondary water supply channel and obtain secondary water level information according to the working instruction; the third controller 1213 is also used to transmit the primary water level information and secondary water level information to the water pump control unit 122 through the second power carrier subunit 1214.

[0118] It will be understood that the third controller 1213 is electrically connected to both the first power carrier subunit 1123 and the water pump control unit 122 via the second power carrier subunit 1214. After receiving the modulated signal provided by the first power carrier subunit 1123, the second power carrier subunit 1214 parses the modulated signal to obtain a working instruction and operating power, and transmits the working instruction and operating power to the third controller 1213. After receiving the working instruction, the third controller 1213 controls the primary water level sensor 1211 and the secondary water level sensor 1212 to collect water level information, and transmits the primary water level information collected by the primary water level sensor 1211 and the secondary water level information collected by the secondary water level sensor 1212 to the second power carrier subunit 1214. The second power carrier subunit 1214 then transmits the primary water level information and the secondary water level information to the water pump control unit 122.

[0119] The primary water level sensor 1211 and the secondary water level sensor 1212 can both be water level sensors. The third controller 1213 can be a single-chip microcomputer, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. The second power carrier subunit 1214 can be a power carrier module.

[0120] like Figure 8 As shown, the first water level detection unit 121 further includes a fourth voltage conversion subunit 1215, and the second power carrier subunit 1214 is electrically connected to the third controller 1213 via the fourth voltage conversion subunit 1215. The fourth voltage conversion subunit 1215 is configured to convert the operating electrical energy into the electrical energy required for the operation of the third controller 1213. The fourth voltage conversion subunit 1215 may be a DC-DC conversion module.

[0121] like Figure 8 As shown, the water pump control unit 122 includes a fourth controller 1221, a third power carrier subunit 1222 and a switch 1224. The fourth controller 1221 is electrically connected to the first water level detection unit 121 through the third power carrier subunit 1222. The fourth controller 1221 is also electrically connected to the switch 1224, and the switch 1224 is electrically connected to the water pump 123.

[0122] In this embodiment, the fourth controller 1221 is used to receive primary water level information and secondary water level information through the third power carrier subunit 1222; the fourth controller 1221 is also used to control the on and off of the switch 1224 according to the primary water level information and the secondary water level information, thereby controlling whether the water pump 123 is working.

[0123] It will be understood that the fourth controller 1221 is electrically connected to the second power carrier subunit 1214 via the third power carrier subunit 1222. After obtaining the primary water level information, the fourth controller 1221 compares the primary water level information with the first preset water level information. If the value corresponding to the primary water level information is lower than the value corresponding to the first preset water level information, the fourth controller 1221 controls the switch 1224 to be turned off, thereby controlling the water pump 123 to stop operating. When the value corresponding to the primary water level information is lower than the value corresponding to the first preset water level information, it indicates that the low water point in the primary water supply channel is lower than the installation position of the water pump 123. If the water pump 123 continues to operate, it will damage the water pump 123 due to idling. Therefore, the water pump 123 must be controlled to stop operating, thereby stopping the pumping of water from the primary water supply channel into the secondary water supply channel. If the value corresponding to the primary water level information is not lower than the value corresponding to the first preset water level information, the fourth controller 1221 controls the switch 1224 to be turned on, thereby controlling the water pump 123 to operate. When the value corresponding to the primary water level information is not lower than the value corresponding to the first preset water level information, it indicates that the low water point in the primary water supply channel is higher than the installation position of the water pump 123, and the water pump 123 will not idle, so the water pump 123 can work normally to pump the water in the primary water supply channel into the secondary water supply channel.

[0124] After obtaining the secondary water level information, the fourth controller 1221 compares the secondary water level information with the second preset water level information. If the value corresponding to the secondary water level information is higher than the value corresponding to the second preset water level information, the fourth controller 1221 controls the switch 1224 to be in the off state, thereby controlling the water pump 123 to stop working. Because the water storage level of the secondary water supply channel in this application is higher than the water storage level of the primary water supply channel, when the value corresponding to the secondary water level information is higher than the value corresponding to the second preset water level information, it indicates that the water in the secondary water supply channel is higher than the high water point. The water in the secondary water supply channel will flow back into the primary water supply channel. Therefore, it is necessary to control the water pump 123 to stop working, and there is no need to pump the water in the primary water supply channel into the secondary water supply channel.

[0125] In this embodiment, in addition to automatically controlling the on and off of the switch 1224 according to the primary water level information and the secondary water level information through the fourth controller 1221, the primary water level information and the secondary water level information can also be fed back to the user terminal 200, and the user can manually operate the on and off of the switch 1224 according to the primary water level information and the secondary water level information.

[0126] Specifically, the third controller 1213 may also transmit the primary water level information and the secondary water level information to the first power carrier subunit 1123 via the second power carrier subunit 1214. The first power carrier subunit 1123 then transmits the information to the first controller 1111 via the second controller 1121 and the third communication subunit 1122. The first controller 1111 then transmits the primary water level information and the secondary water level information to the user terminal 200 via the first communication subunit 1112. The user obtains the primary water level information and the secondary water level information through the user terminal 200 and manually operates the user terminal 200 to send a water supply control instruction to the first controller 1111. The first controller 1111 sends the water supply control instruction to the second controller 1121 via the second communication subunit 1113 and the third communication subunit 1122. The second controller 1121 sends the water supply control instruction to the third power carrier subunit 1222 via the first power carrier subunit 1123. The third power carrier subunit 1222 sends the water supply control instruction to the fourth controller 1221. The fourth controller 1221 controls the on and off of the switch 1224 according to the water supply control instruction, thereby controlling whether the water pump 123 is operating.

[0127] In this embodiment, the fourth controller 1221 also obtains real-time operating status information of the water pump 123 and transmits the real-time operating status information to the second controller 1121 via the third power carrier subunit 1222 and the first power carrier subunit 1123. The second controller 1121 sends the real-time operating status information to the first controller 1111 via the third communication subunit 1122 and the second communication subunit 1113. The first controller 1111 transmits the real-time operating status information to the user terminal 200 via the first communication subunit 1112. The user terminal 200 stores and displays the real-time operating status information.

[0128] In this embodiment, the fourth controller 1221 may be a single-chip microcomputer, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. The third power carrier subunit 1222 may be a power carrier module. The switch 1224 may be a relay.

[0129] like Figure 8As shown, the water pump control unit 122 further includes a fifth voltage conversion subunit 1223, through which the third power carrier subunit 1222 is electrically connected to the fourth controller 1221. The fifth voltage conversion subunit 1223 is configured to convert the operating power obtained by the third power carrier subunit 1222 to obtain the power required for the operation of the fourth controller 1221. The fifth voltage conversion subunit 1223 may be a DC-DC conversion module.

[0130] like Figure 8 As shown, the water pump 123 may include a motor and a motor control unit, which is electrically connected to the motor, the switch 1224, and the power grid 400. The power grid 400 is used to provide the motor control unit with the required operating voltage, and the switch 1224 is used to send a motor operating signal to the motor control unit. The motor control unit controls the motor operation according to the motor operating signal, thereby achieving the water pumping operation.

[0131] like Figure 9 As shown, it is another feasible structural diagram of the irrigation device 100 provided in this embodiment. The inlet and outlet control module 130 includes a second water level detection unit 131, a water inlet control unit 132 and a water outlet control unit 133. The second water level detection unit 131 is electrically connected to the water inlet control unit 132, the water outlet control unit 133 and the main control module 110. The water inlet control unit 132 is electrically connected to the water inlet switch 134, and the water outlet control unit 133 is electrically connected to the water outlet switch 135. Figure 10 , which is a schematic diagram of another applicable application environment of the irrigation device 100 provided in this embodiment, the water inlet switch 134 is provided at the connection between the irrigation area and the water supply channel, and the drainage switch 135 is provided at the connection between the irrigation area and the drainage channel.

[0132] In this embodiment, the second water level detection unit 131 is used to collect the second water level information of the irrigation area according to the work instruction; the second water level detection unit 131 is also used to send an irrigation command to the water inlet control unit 132 or send a drainage command to the drainage control unit 133 according to the second water level information; the water inlet control unit 132 is used to control the water inlet switch 134 to turn on according to the irrigation command; the drainage control unit 133 is used to control the drainage switch 135 to turn on according to the drainage command.

[0133] It will be appreciated that the second water level detection unit 131 is electrically connected to the first power carrier subunit 1123. After receiving the modulated signal from the first power carrier subunit 1123, the second water level detection unit 131 parses the modulated signal to obtain a working instruction and working power. The second water level detection unit 131 obtains the required power for operation based on the working power and collects the second water level information of the irrigation area based on the working instruction.

[0134] like Figure 11 As shown, the second water level detection unit 131 includes an irrigation water level sensor 1311, a fifth controller 1312, and a fourth power carrier subunit 1313. The fifth controller 1312 is electrically connected to the water inlet control unit 132, the drainage control unit 133 and the main control module 110 through the fourth power carrier subunit 1313. The fifth controller 1312 is also electrically connected to the irrigation water level sensor 1311, and the irrigation water level sensor 1311 is set in the irrigation area.

[0135] In this embodiment, the fifth controller 1312 is used to control the irrigation water level sensor 1311 to collect the second water level information of the irrigation area according to the working instruction, and obtain the second water level information; the fifth controller 1312 is also used to generate an irrigation command or a drainage command based on the second water level information, and send the irrigation command to the water inlet control unit 132 through the fourth power carrier subunit 1313, or send the drainage command to the drainage control unit 133 through the fourth power carrier subunit 1313.

[0136] In this embodiment, the fifth controller 1312 is electrically connected to the first power carrier subunit 1123 via the fourth power carrier subunit 1313. After receiving the modulated signal, the fourth power carrier subunit 1313 parses the modulated signal to obtain a working instruction and working power, and transmits the working instruction and working power to the fifth controller 1312. After receiving the working power, the fifth controller 1312 begins operation and controls the irrigation water level sensor 1311 to collect and obtain the second water level information of the irrigation area according to the working instruction.

[0137] The fifth controller 1312 compares the second water level information with the third and fourth preset water level information. If the value corresponding to the second water level information is lower than the value corresponding to the third preset water level information, the fifth controller 1312 generates a flooding command and sends the flooding command to the water inlet control unit 132 via the fourth power carrier subunit 1313. If the value corresponding to the second water level information is lower than the value corresponding to the third preset water level information, this indicates that the water level in the irrigation area is too low and requires flooding. If the value corresponding to the second water level information is higher than the value corresponding to the fourth preset water level information, the fifth controller 1312 generates a draining command and sends the draining command to the drain control unit 133 via the fourth power carrier subunit 1313. If the value corresponding to the second water level information is higher than the value corresponding to the fourth preset water level information, this indicates that the water level in the irrigation area is too high and requires drainage. The third preset water level information is lower than the fourth preset water level information.

[0138] In this embodiment, in addition to automatically controlling the water inlet control unit 132 and the drainage control unit 133 according to the second water level information through the fifth controller 1312, the second water level information can also be fed back to the user terminal 200, and the user can manually operate the water inlet control unit 132 and the drainage control unit 133 according to the second water level information.

[0139] Specifically, after obtaining the second water level information, the fifth controller 1312 does not generate a fill or drain command based on the second water level information. Instead, it transmits the second water level information to the second controller 1121 via the fourth power carrier subunit 1313 and the first power carrier subunit 1123. The second controller 1121 transmits the second water level information to the first controller 1111 via the third communication subunit 1122 and the second communication subunit 1113. The first controller 1111 transmits the second water level information to the user terminal 200 via the first communication subunit 1112. The user obtains the second water level information through the user terminal 200 and manually operates the user terminal 200 to send a fill or drain command to the first controller 1111. The first controller 1111 sends the fill or drain command to the second controller 1121 via the second communication subunit 1113 and the third communication subunit 1122. If the command is a fill command, the second controller 1121 transmits the fill command to the water inlet control unit 132 via the first power carrier subunit 1123. If it is a drainage command, the second controller 1121 transmits the drainage command to the drainage control unit 133 via the first power carrier subunit 1123 .

[0140] like Figure 11 As shown, the second water level detection unit 131 further includes a sixth voltage conversion subunit 1314, and the fourth power carrier subunit 1313 is electrically connected to the fifth controller 1312 via the sixth voltage conversion subunit 1314. The sixth voltage conversion subunit 1314 is used to convert the operating power obtained by the fourth power carrier subunit 1313 to obtain the power required for the operation of the fifth controller 1312.

[0141] The sixth voltage conversion subunit 1314 can be a DC-DC conversion module. The fifth controller 1312 can be a single-chip microcomputer, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. The fourth power carrier subunit 1313 can be a power carrier module. The irrigation water level sensor 1311 is a water level sensor.

[0142] like Figure 11 As shown, the water inlet control unit 132 includes a fifth power carrier subunit 1321, a sixth controller 1322 and a first switch control subunit 1323. The sixth controller 1322 is used to be electrically connected to the second water level detection unit 131 through the fifth power carrier subunit 1321. The sixth controller 1322 is also electrically connected to the first switch control subunit 1323, and the first switch control subunit 1323 is electrically connected to the water inlet switch 134.

[0143] In this embodiment, the sixth controller 1322 is used to receive the water filling command through the fifth power carrier subunit 1321; the sixth controller 1322 is further used to control the first switch control subunit 1323 to operate according to the water filling command, so as to control the water inlet switch 134 to be turned on.

[0144] It can be understood that the sixth controller 1322 is electrically connected to both the first power carrier subunit 1123 and the fourth power carrier subunit 1313 via the fifth power carrier subunit 1321. The sixth controller 1322 receives the flooding command sent by the first power carrier subunit 1123 or the fourth power carrier subunit 1313 via the fifth power carrier subunit 1321.

[0145] The water inlet switch 134 may be a valve or gate valve. The first switch control subunit 1323 may include a valve motor, which drives the water inlet switch 134 to open according to the irrigation command, allowing water in the water supply channel to flow into the irrigation area. The fifth power carrier subunit 1321 may be a power carrier module. The sixth controller 1322 may be a single-chip microcomputer, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc.

[0146] like Figure 11 As shown, the water inlet control unit 132 also includes a seventh voltage conversion subunit 1324, through which the fifth power carrier subunit 1321 is electrically connected to the sixth controller 1322. The seventh voltage conversion subunit 1324 is configured to convert the operating power obtained by the fifth power carrier subunit 1321 to obtain the power required for the operation of the sixth controller 1322. The seventh voltage conversion subunit 1324 may be a DC-DC conversion module.

[0147] like Figure 11As shown, the drainage control unit 133 includes a sixth power carrier subunit 1331, a seventh controller 1332 and a second switch control subunit 1333. The seventh controller 1332 is used to be electrically connected to the second water level detection unit 131 through the sixth power carrier subunit 1331. The seventh controller 1332 is also electrically connected to the second switch control subunit 1333. The second switch control subunit 1333 is electrically connected to the drainage switch 135.

[0148] In this embodiment, the seventh controller 1332 is used to receive a drainage command through the sixth power carrier subunit 1331 ; the seventh controller 1332 is also used to control the second switch control subunit 1333 to operate according to the drainage command, so as to control the drainage switch 135 to be turned on.

[0149] It can be understood that the seventh controller 1332 is electrically connected to both the first power carrier subunit 1123 and the fourth power carrier subunit 1313 via the sixth power carrier subunit 1331. The seventh controller 1332 receives the drain command sent by the first power carrier subunit 1123 or the fourth power carrier subunit 1313 via the sixth power carrier subunit 1331.

[0150] The drainage switch 135 may be a valve or gate valve. The second switch control subunit 1333 may include a valve motor that drives the drainage switch 135 to open according to the drainage command, so that excess water in the irrigation area flows into the drainage channel. The sixth power carrier subunit 1331 may be a power carrier module. The seventh controller 1332 may be a single-chip microcomputer, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc.

[0151] like Figure 11 As shown, the drainage control unit 133 further includes an eighth voltage conversion subunit 1334, through which the sixth power carrier subunit 1331 is electrically connected to the seventh controller 1332. The eighth voltage conversion subunit 1334 is configured to convert the operating power obtained by the sixth power carrier subunit 1331 to obtain the power required for the operation of the seventh controller 1332. The eighth voltage conversion subunit 1334 may be a DC-DC conversion module.

[0152] Please refer to Figure 12, which is another schematic diagram of another possible implementation of the irrigation device 100 provided in this embodiment. The irrigation device 100 also includes an auxiliary module 140, which is electrically connected to the main control module 110. The auxiliary module 140 is configured to monitor weather information, soil information, and crop growth information according to work instructions, and to feed this information back to the main control module 110. The auxiliary module 140 is also configured to issue bird repellent information according to work instructions.

[0153] It is understood that auxiliary module 140 may include a weather monitoring unit, a soil monitoring unit, a crop monitoring unit, and a bird repellent. The weather monitoring unit includes a wind speed sensor, a wind direction sensor, a light sensor, and a rainfall sensor. The soil monitoring unit includes a temperature and humidity sensor, a pH meter, and a soil fertility meter. The crop monitoring unit includes a farmland recorder. Weather information includes wind speed, wind direction, rainfall, and light information. Soil information includes soil temperature and humidity, soil pH, and soil fertility information.

[0154] The load module is electrically connected to the first power carrier subunit 1123, and receives operating power and operating instructions from the first power carrier subunit 1123 to achieve operation. The bird repellent signal emitted by the bird repellent can repel birds and prevent food production losses. The meteorological monitoring unit monitors meteorological information, allowing the crop growth environment to be monitored. The crop monitoring unit obtains crop growth information, allowing crop growth conditions to be recorded.

[0155] In this embodiment, the main control module 110 is electrically connected to the water supply control module 120 and the water inlet and outlet control module 130 through a non-polarity two-wire low-voltage power carrier bus, which can be a single bus control mode, an independent bus control mode, or a mixed bus control mode.
