[0002] In the field of modern agricultural irrigation, intelligent and precision irrigation has become a key means to improve water resource utilization and ensure crop yields. With the rapid development of smart agriculture, irrigation systems are placing higher demands on the functionality, flexibility, and automation of electric valves.

[0003] The existing multi-channel independently adjustable integrated wireless smart irrigation electric valve cannot meet the differentiated irrigation needs of different regions and crops at the same time because a single-channel electric valve cannot meet the differentiated irrigation needs of different regions and crops at the same time. If multiple single-channel valves are combined, it will not only increase the equipment cost and installation complexity, but also lead to system redundancy.

[0004] When deploying traditional electric irrigation valves, the selection of installation areas relies on experience, which can easily lead to problems such as remote control delays and command failures after installation, affecting the accuracy of irrigation. As a key carrier for wireless communication of electric valves, the signal pole is prone to angular deviation due to natural and human factors, and it is difficult to restore the optimal communication angle through active adjustment, which in turn leads to the deterioration of signal transmission quality and reduces the reliability of irrigation control. Therefore, the above-mentioned technical problems need to be addressed. Summary of the Invention

By analyzing the free space loss, crop shading loss, and building shading loss in a hierarchical manner, the total transmission loss is obtained. Combined with the comparison between the theoretical receiving strength and the receiving sensitivity of the electric valve, the communication risk in different areas is accurately determined, the impact of shading on the signal is quantified, and the transmission loss in the selected installation area is minimized. This reduces the loss or delay of commands caused by shading from the source and improves the reliability of remote control. 3. The system calculates and analyzes the offset angle through the analysis unit, and responds in real time to the angle offset caused by wind, rain, and collisions (such as tilting caused by strong winds or skewing after mechanical collisions). The degree of offset is accurately quantified by the spring length difference to ensure that the signal pole is always at the optimal receiving angle and to reduce signal attenuation caused by angle offset.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] Example 1: See Figure 1-6This invention discloses a multi-channel independently adjustable integrated wireless intelligent irrigation electric valve, comprising a valve body 1 and an F-shaped water guide channel opened inside the valve body 1. An inlet pipe 5 is installed at the inlet of the F-shaped water guide channel, and a first outlet pipe 6 and a second outlet pipe 7 are respectively installed at the outlet of the F-shaped water guide channel. A channel adjustment mechanism is installed at the connection between the first outlet pipe 6 and the inlet pipe 5. A protective box 2 is installed on the upper end of the valve body 1. Inside the protective box 2 are a drive motor 9, a wireless communication module 12, a control module 11, and a power module 10. The protective box 2 is fixed to the valve body 1 by fixing bolts 3. The valve body 1 is connected via the F-shaped water guide channel and the inlet pipe 5. The first water outlet pipe 6 and the second water outlet pipe 7, together with the drive motor 9, wireless communication module 12, control module 11 and power module 10 in the protective box 2, facilitate the realization of multi-channel water delivery and wireless intelligent control functions of the irrigation electric valve; a circular groove is opened through the connection between the first water outlet pipe 6 and the water inlet pipe 5, and a multi-channel valve core 14 is rotatably installed in the circular groove. The top of the multi-channel valve core 14 is fixedly connected to the bottom of the rotating plate 15. By rotatably installing the multi-channel valve core 14 in the circular groove at the connection between the first water outlet pipe 6 and the water inlet pipe 5, and fixing the multi-channel valve core 14 to the rotating plate 15, it is convenient to switch and adjust the water flow channels; To overcome the limitations of existing dual-channel and on / off regulation, improvements can be made in two aspects: structural upgrades and control precision optimization. Structurally, the F-shaped water guide channel is upgraded to a "star-shaped multi-branch structure". That is, based on the main water inlet channel, 3-6 outlet pipes are connected through an internal flow chamber (customized according to the needs of farmland zoning). Each outlet pipe is independently equipped with a multi-channel valve core and a micro drive motor at the connection between it and the main channel, realizing independent control of "one valve for multiple zones" without the need for additional equipment. In terms of adjustment precision, the valve core is modularly designed: 3-5 guide holes of different diameters (such as φ2mm, φ5mm, φ8mm) are opened on the surface of the valve core to correspond to different flow levels; the drive motor adopts a stepper motor (with an accuracy of up to 0.9° / step), which, together with the pulse signal algorithm in the control module, can precisely control the rotation angle of the valve core to achieve multi-level adjustment of "fully closed - small flow - medium flow - large flow - fully open"; for example, the orifice diameter can be adjusted to φ2mm for seedling areas and to φ8mm for mature plant areas to meet the needs of fine irrigation.

[0020] In this invention, the channel adjustment mechanism includes a slot at the upper center of a rotating plate 15, which is rotatably mounted inside a fixed plate 8. A drive motor 9 is mounted on the upper end of the fixed plate 8, and the output end of the drive motor 9 passes through the fixed plate 8 and is engaged in the slot on the rotating plate 15. Through the cooperation of the slot on the rotating plate 15, the fixed plate 8, and the drive motor 9, the rotation control of the multi-channel valve core 14 is easily realized. The wireless communication module 12 is bolted to the inner wall of the protective box 2, and a signal hinge block is provided at the upper end of the wireless communication module 12, penetrating the protective box 2. The system is equipped with a signal rod 4, which facilitates wireless signal transmission between the electric valve and external devices via the wireless communication module 12, signal hinge block, and signal rod 4. Multiple signal connection ports are provided on both sides of the control module 11, enabling connection to various external devices or sensors. The power module 10 is bolted to the inner wall of the protective box 2, and a charging port 13 is installed on one side of the power module 10, penetrating the protective box 2. The power module 10 and charging port 13 facilitate stable power supply and convenient charging of the electric valve. To address power dependence and battery life issues, a "multi-source power supply + intelligent power management" system needs to be constructed. For power supply, a 10W monocrystalline silicon solar panel (approximately 20cm x 30cm) is integrated on the top of the protective box. Connected to the power module via an MPPT charge / discharge controller, it can generate over 150Wh per day under sufficient sunlight (e.g., sunny days), meeting the device's daily power consumption (approximately 50Wh / day) while simultaneously charging the built-in lithium battery (5000mAh capacity), achieving "photovoltaic-energy storage integrated" power supply. It can operate continuously for 7-10 days (even on cloudy or rainy days) completely off the grid. In terms of power consumption management, the control module is equipped with an intelligent sleep algorithm: when the device is inactive for 30 consecutive minutes, it automatically shuts down the real-time receiving function of the wireless communication module, retaining only the low-power wake-up module (power consumption reduced to below 0.5W). If a remote terminal sends a command, the wake-up module will immediately activate the system. In addition, the power module is equipped with a Type-C fast charging interface (supporting 20W fast charging), which can be charged by a power bank in an emergency, reaching 50% charge in 30 minutes, thus avoiding irrigation interruption due to power failure. To cope with complex field environments, both the protection level and material performance need to be strengthened. The protective box adopts an IP68 waterproof design (it can be submerged in 1 meter of water for 30 minutes without water ingress). A fluororubber sealing ring (temperature resistance range -20℃~200℃) is installed at the connection between the box body and the valve body. The passage between the signal pole and the protective box adopts a corrugated pipe sealing structure to prevent rainwater and dew from seeping in. The internal circuit board is coated with a 0.2mm thick layer of three-proof paint (waterproof, moisture-proof, and corrosion-proof), so even if a small amount of moisture enters, it will not cause a short circuit. To address extreme temperatures, an intelligent temperature control module is installed inside the protective box: when the temperature exceeds 50℃, a miniature cooling fan (3W power) automatically starts, expelling hot air through the ventilation holes on the side of the box; when the temperature drops below -10℃, a heating element (5W power) is activated to maintain the internal temperature above 5℃, ensuring the normal operation of the lithium battery and electronic components; the valve body is made of 304 stainless steel (its rust resistance is more than 5 times that of ordinary steel), and the surface is sandblasted and then coated with outdoor-specific powder coating, which can withstand long-term ultraviolet radiation without fading or cracking, extending its service life to 8-10 years.

[0021] Example 2: See Figure 7 The control module 11 also has an intelligent control component, which includes a data acquisition unit, an analysis unit, and an execution unit. The data acquisition unit collects data on obstructions, the four angles of the signal pole, and the length of the telescopic spring, and then transmits the collected data to the analysis unit. The analysis unit analyzes the obstruction data transmitted from the acquisition unit, calculates the transmission loss of the installation area, and selects the area with the minimum transmission loss as the installation area; it also analyzes the angle and length data transmitted from the acquisition unit to determine whether the signal rod 4 has shifted. If it has shifted, it generates an adjustment signal and transmits the adjustment signal to the execution unit. The loss of wireless signals when propagating in free space Only related to the distance of transmission With operating frequency Related, free propagation loss In reality, the propagation of wireless signals is also affected by obstructions. "32.45" is a standard constant in the field of wireless communication, derived from the theoretical derivation of the free space propagation model (based on 1mW, combined with the relationship between the speed of light and wavelength). The straight-line distance (unit: km) from the transmitter to the receiver of the signal needs to be measured in practice with the wireless communication module of the electric valve as the receiver and the remote control terminal as the transmitter to ensure that the influence of terrain undulations is included (such as the slope in farmland needs to be corrected to the horizontal distance). The operating frequency (unit: MHz) is commonly used in agricultural applications. 433MHz (strong resistance to signal obstruction) or 868MHz (long transmission distance) are frequently used. The higher the frequency, the weaker the signal diffraction capability, and the faster the loss increases (e.g., increasing the frequency from 433MHz to 868MHz increases the loss by approximately 6dB over the same distance); logarithmic operations ( The purpose of this is to transform exponentially increasing losses into linear superposition, which facilitates engineering calculations (e.g., when the distance doubles, the loss increases by 6dB, which is consistent with...). (The pattern) The installation area is divided according to the size of the area occupied by the electric valve during installation. After division, areas smaller than the installed area are removed. Crop height data is obtained for the remaining areas, and the average crop height in the corresponding area is calculated based on the height data of all crops in that area. A line is drawn connecting the signal receiver and the signal transmitter. The length of this line, excluding areas with crops, is calculated and recorded as the distance the signal travels through the crop area. The average height data of other crops within the crop area existing along the line. The average height of the crop was obtained. The loss of wireless signals due to crop shading. , , , This is an empirical coefficient; , , These are empirical coefficients and need to be calibrated through field testing: for example, in cornfields, A≈0.002, B≈0.6, C≈1.2 (the taller the crop and the greater the density, the larger the C value), while in wheatfields, because the plants are short, C can be reduced to 0.8; The average height of crops (unit: m) should be calculated to cover all crops within a 5m radius around the electric valve installation point. After removing extreme values ​​(such as individual dead plants), the arithmetic mean should be taken to ensure that the overall shading level is reflected. It is the distance the signal travels through the crop area (unit: km), which needs to be measured along the line connecting the transmitter and receiver using a laser rangefinder. If there are no crops in some areas of the line (such as field ridges), only the length of the line segment with crops is calculated. The degree of obstruction by buildings , This refers to the height of the building's top relative to the line connecting the transmitting and receiving antennas. , and These represent the distance from the transmitter to the building and the distance from the building to the receiver, respectively. For wavelength; when When the building's shading effect is determined to be strong shading, the loss is... ;when When the building's shading effect is determined to be unshaded or weakly shaded, the resulting loss is negligible. Loss This formula is applicable to single, isolated buildings (such as farmland caretaker's quarters). If multiple buildings are distributed along the signal path, the loss of each building needs to be calculated separately and then summed (e.g., if two buildings each cause 10dB of loss, the total loss is 20dB). The formula assumes that the buildings are "edge-shaped" (such as pointed roofs). If they are flat or curved, the formula needs to be corrected. (Taking the average height), the loss may increase by 5-10 dB at this point. In summary, the total loss of wireless signals during transmission... Theoretical reception strength when there is obstruction , For transmitting power, and These are the gain power of the transmitting and receiving antennas, respectively; if If the signal is lower than the receiving sensitivity of the electric valve, then the risk of communication interruption due to obstruction is considered high; if Higher than the receiving sensitivity of an electric valve, but with significant attenuation (the theoretical difference in received strength between the two conditions with and without obstruction is greater than...). If the signal is determined to be significantly weakened, then it is determined that there is a risk of instruction delay or loss, an alarm signal is generated, and the alarm signal is transmitted to the execution unit. The unit is , Units are , and Units are In the communication link power budget, , Those belonging to the same "logarithmic power domain" can be directly added or subtracted; After receiving the warning signal, the execution unit will sound an alarm through the buzzer inside the intelligent control component to remind the staff that the installation area is not suitable. The receiving intensity data at various locations within the segmented installation area are acquired and compared. Segmented areas with receiving intensity data higher than the receiving sensitivity of the electric valve and no significant attenuation are marked, and the area with the smallest loss among the marked areas is selected as the installation area.

[0022] Inside the protective box 2, at the position corresponding to the signal rod 4, a traction assembly is provided. The traction assembly includes a traction line. One end of the traction line passes through the protective box 2 and is connected to the upper left outer wall of the signal rod 4. The other end of the traction line is located inside the protective box 2 on the right side and is connected to the telescopic rod through a telescopic spring. The telescopic rod is installed at the top of the protective box 2. A traction assembly is installed on each side of the outer wall of the signal rod 4. After the angle of signal rod 4 shifts, the length of the telescopic spring becomes , This refers to the horizontal distance between the through hole of the traction cable on the protective box 2 and the installation position of the signal pole 4. The vertical height between the installation position of the traction line on signal pole 4 and the surface of protective box 2. The size of the deflection angle; Simplified to At the offset angle When I was very young ( ), ≈ ,but , offset angle The radius of curvature; the initial length of the extension spring. The change in length of the extension spring ; After the signal pole 4 deviates at an angle, the lengths of the telescopic springs on both sides of the signal pole 4 will change, with the length on one side becoming... The length on the other side becomes The difference between the two ,Will Convert to degrees and then calculate the offset angle. The calculated offset angle With the detected offset angle If the two are the same, it is determined that the angle of signal rod 4 has deviated, an adjustment signal is generated, and the adjustment signal is transmitted to the execution unit; otherwise, it is determined that the detection is wrong, and the detection is repeated. If the detection result is still determined to be wrong, a maintenance signal is generated and transmitted to the execution unit. After receiving the adjustment signal, the execution unit controls the telescopic rod on the shorter side of the telescopic spring to shorten its length. During the shortening process, the length of the telescopic spring gradually increases. When the length of the telescopic spring is greater than that on the other side, the signal rod 4 with the angle deviation is reset and the process stops. Then, the lengths of the telescopic rods on both sides of the signal rod 4 are automatically adjusted back to their initial lengths. After receiving the maintenance signal, the execution unit sends the maintenance signal for signal pole 4 to the maintenance personnel through the wireless communication module inside the intelligent control component, and displays the judgment result.

[0023] Working Principle: In the use of this invention, water first flows into the valve body 1 through the inlet pipe 5. When the valve body 1 needs to be opened, a wireless signal from the remote control terminal is received through the signal rod 4. Then, the received command is converted into an electrical signal through the wireless communication module 12 and transmitted to the control module 11. The control module 11 then analyzes the command based on the signal received, identifies the channel that needs to be adjusted, and the corresponding water flow adjustment requirements. According to the preset program and algorithm, the control module 11 converts the command into a control signal for the drive motor 9. When the first outlet pipe 6 needs to be closed, the multi-channel valve core 14 drives the motor... 9. Rotate to completely block the connection between the inlet pipe 5 and the first outlet pipe 6, blocking the water flow, so that the water flows out from the second outlet pipe 7. When it is necessary to open the first outlet pipe 6, the multi-channel valve core 14 rotates to the connection of the second outlet pipe 7, blocking the water flow, so that the water flows out from the first outlet pipe 6. When it is not necessary to pass through, the multi-channel valve core 14 completely blocks the inlet pipe 5, thereby preventing water flow. The solenoid valve can be charged by connecting to the charger through the charging port 13 to ensure that the equipment has sufficient power to operate. At the same time, confirm that the circuit connection of the power module 10, control module 11, drive motor 9 and other components is normal. After signal pole 4 tilts at an angle, proceed.

For wavelength; when When the building's shading effect is determined to be strong shading, the loss is... ;when When the building's shading effect is determined to be unshaded or weakly shaded, the resulting loss is negligible. S5: Total loss of wireless signal during transmission Theoretical reception strength when there is obstruction , For transmitting power, and These are the gain power of the transmitting and receiving antennas, respectively. S6: If If the signal is lower than the receiving sensitivity of the electric valve, then the risk of communication interruption due to obstruction is considered high; if If the sensitivity is higher than that of the electric valve but the attenuation is significant, it is determined that there is a risk of command delay and loss.

9. The multi-channel independently adjustable integrated wireless intelligent irrigation electric valve according to claim 1, characterized in that: The analysis steps for the signal rod (4) deflection angle by the analysis unit are as follows: K1: After the angle of the signal rod (4) shifts, the length of the telescopic spring becomes , The horizontal distance between the through hole of the traction line on the protective box (2) and the installation position of the signal pole (4) is given. The vertical height between the installation position of the traction line on the signal pole (4) and the surface of the protective box (2) is given. The size of the deflection angle; K2: In offset angle When I was very young ( ), ≈ ,but , offset angle The radius of curvature; the initial length of the extension spring. The change in length of the extension spring ; K3: After the signal pole (4) undergoes an angular shift, the lengths of the extension springs on both sides of the signal pole (4) will change, with the length on one side becoming... The length on the other side becomes The difference between the two ,Will Convert to degrees and then calculate the offset angle. The calculated offset angle With the detected offset angle Compare; K4: If the two are the same, it is determined that the angle of the signal rod (4) has deviated, an adjustment signal is generated, and the adjustment signal is transmitted to the execution unit; otherwise, it is determined that the detection is wrong, and the detection is repeated. If the detection result is still determined to be wrong, a maintenance signal is generated and the maintenance signal is transmitted to the execution unit.
