[0002] Jujube trees are an important economic fruit tree, and their flowering period management is crucial for improving fruit set rate and fruit quality. In southern Xinjiang, on the one hand, evaporation is extremely high and the climate is dry with little rainfall during the jujube flowering period; on the other hand, southern Xinjiang often experiences sandstorms during the jujube flowering period (May-June). These adverse weather conditions are extremely detrimental to pollen germination and pollen tube growth, easily leading to "flower burn," making it difficult for jujube trees to pollinate, and consequently causing a large number of flower and fruit drops. In addition, traditional jujube flowering period management methods suffer from low efficiency, high labor costs, and unstable results. To address these issues, we propose an IoT-based mist irrigation system for jujube trees to achieve automated irrigation. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model provides a technical solution: a jujube tree mist irrigation system based on Internet of Things control, including an integrated weather station, which is equipped with a wind speed and direction sensor, a temperature and humidity sensor, and PM2.5 and PM10 sensors.

[0024] It also includes an RS485 to TTL module, a microcontroller, a CH376 USB flash drive module, a master power supply module, a serial port display, relays, mist irrigation equipment, and a water pump power supply module;

[0025] The mist irrigation equipment includes a water storage tank 1, a water pump 2, and a filter 3. The water storage tank 1 is connected to the water pump 2 through a pipe, and the water pump 2 is connected to the filter 3 through a pipe. The output end of the filter 3 is fixedly connected to a main pipe 4, and a branch pipe 5 is fixedly connected to the outer wall of the main pipe 4. A spray pipe structure 6 is provided on the branch pipe 5. The spray pipe structure 6 includes a telescopic pipe 601, which is composed of a fixed pipe 6011 and a movable pipe 6012. One end of the fixed pipe 6011 is connected to the branch pipe 5, and a striker nozzle 602 is fixedly connected to the top end of the telescopic pipe 601.

[0026] The integrated weather station transmits data to the RS485 to TTL module, which in turn transmits the data to the microcontroller. The microcontroller displays the data via a serial port display screen. The microcontroller controls the serial port display screen and is electrically connected to a relay. The main power supply module is electrically connected to the integrated weather station, the RS485 to TTL module, the microcontroller, the CH376 USB flash drive module, the serial port display screen, and the relay. The relay is electrically connected to water pump 2, and the water pump power supply module is electrically connected to the water pump.

[0027] In this implementation plan, the wind speed and direction sensor, temperature and humidity sensor, and PM2.5 and PM10 sensors in the integrated weather station work together to monitor environmental data in real time during the jujube blossom season in southern Xinjiang. After acquiring the data, the data is transmitted to the microcontroller (STM32F103ZET6 microcontroller) via an RS485 to TTL module. The RS485 to TTL module plays a crucial role in data format conversion, enabling the microcontroller to recognize and process the data. After receiving the data, the microcontroller analyzes and processes it according to preset algorithms and thresholds. When any of the PM2.5 / PM10 values, temperature, or humidity in the environment reaches a set threshold, the microcontroller will make a decision to start irrigation. For example, in a high-temperature and low-humidity environment, if the humidity is below the set lower limit, the microcontroller will issue an instruction to start irrigation. The microcontroller also transmits the data to a serial port display screen, allowing staff to view the environmental data in real time.

[0028] After receiving the data, the microcontroller sends a signal to the relay to control the relay to turn on. The relay is electrically connected to the water pump. After the relay is turned on, the water pump power supply module supplies power to the water pump, causing the water pump to start working.

[0029] Water pump 2 draws water from water storage tank 1 and delivers it to filter 3 through pipeline. Filter 3 removes impurities from the water, ensuring that the water entering the irrigation system is clean and preventing clogging of the nozzles, which would affect the irrigation effect. The filtered water enters main pipe 4, and then is branched from main pipe 4 to branch pipe 5, and finally reaches the nozzle structure 6, where it is sprayed through the impact needle nozzle 602.

[0030] Data storage: The CH376 USB flash drive module stores the collected data into a USB flash drive, ensuring data integrity and traceability, facilitating subsequent data analysis, and providing data support for jujube tree planting and management.

[0031] This patent can be combined with an integrated water, fertilizer and pesticide system, which can accurately deliver water, fertilizer and pesticide to the roots or canopy of jujube trees through automated control, greatly reducing the tediousness of manual operation and improving work efficiency.

[0032] This patent has potential applications in different climate zones. As long as it is appropriately adjusted according to the local climate characteristics, this project can be effective. Different regions have different soil types, and crops have different growth and water requirements. This system can adjust the spraying frequency and water volume according to the water retention capacity and aeration of different soils to meet the growth needs of different crops.

[0033] The outer wall of the fixed pipe 6011 is fixedly connected to a clamp 603. A connecting block 604 is fixedly connected to one side of the outer wall of the clamp 603. A slide rail 605 is fixedly connected to one side of the outer wall of the connecting block 604. A moving block 608 is slidably connected to the inner wall of the slide rail 605. One side of the outer wall of the moving block 608 is fixedly connected to the outer wall of the movable pipe 6012. A lead screw 606 is rotatably connected to the inner wall of the slide rail 605. The outer wall of the lead screw 606 is threadedly connected to the inner wall of the moving block 608. A motor 607 is fixedly connected to the top outer wall of the slide rail 605. The output shaft of the motor 607 is fixedly connected to one end of the lead screw 606.

[0034] Among them, the outer wall of the fixed pipe 6011 is fixedly connected to the clamp 609, and the outer wall of the clamp 609 is movably connected to the support rod 610, which is in contact with the ground.

[0035] In this embodiment, the telescopic pipe 601 in the nozzle structure 6 consists of a fixed pipe 6011 and a movable pipe 6012. When it is necessary to adjust the irrigation height, the motor 607 is started, and the output shaft of the motor 607 drives the lead screw 606 to rotate. The lead screw 606 is threadedly connected to the moving block 608, and the moving block 608 slides in the slide rail 605, thereby driving the movable pipe 6012 to move up and down, so as to realize the adjustment of the height of the telescopic pipe 601. The height of the nozzle can be flexibly adjusted for jujube trees at different growth stages or different terrain conditions to ensure that the mist evenly covers the jujube tree canopy. Water is sprayed out in the form of mist through the impact needle nozzle 602.

[0036] The water pump power supply module includes a solar panel and a 12V lead-acid battery, which are used to provide stable power to water pump 2.

[0037] In this implementation plan, when there is sunlight, the solar panels convert solar energy into electrical energy to power the system.

[0038] The microcontroller is an STM32F103ZET6 microcontroller used to process the acquired data and control the operation of each component.

[0039] The CH376 USB flash drive module is used to store various data collected by the integrated weather station.

[0040] In this implementation plan, the CH376 USB flash drive module stores the collected data into a USB flash drive, ensuring data integrity and traceability, facilitating subsequent data analysis, and providing data support for jujube tree planting and management.

[0041] Working Principle: The integrated weather station utilizes wind speed and direction sensors, temperature and humidity sensors, and PM2.5 and PM10 sensors working in tandem. During the jujube blossom season in southern Xinjiang, these sensors monitor environmental data in real time. After acquiring data, the data is transmitted to a microcontroller (STM32F103ZET6 microcontroller) via an RS485-to-TTL module. The RS485-to-TTL module plays a crucial role in data format conversion, enabling the microcontroller to recognize and process the data. Upon receiving the data, the microcontroller analyzes and processes it according to preset algorithms and thresholds. When any of the PM2.5 / PM10 values, temperature, or humidity in the environment reaches a set threshold, the microcontroller will decide to initiate irrigation. For example, in a high-temperature, low-humidity environment, if the humidity is below a set lower limit, the microcontroller will issue an instruction to start irrigation. The microcontroller also transmits the data to a serial port display screen, allowing staff to view environmental data in real time.

[0042] After receiving the data, the microcontroller sends a signal to the relay to control the relay to turn on. The relay is electrically connected to the water pump. After the relay is turned on, the water pump power supply module supplies power to the water pump, causing the water pump to start working.

[0043] Water pump 2 draws water from water storage tank 1 and delivers it to filter 3 through pipeline. Filter 3 removes impurities from the water, ensuring the water entering the irrigation system is clean and preventing clogging of the nozzles, which would affect the irrigation effect. The filtered water enters main pipe 4, then branches to branch pipes 5, and finally reaches sprinkler structure 6. The telescopic pipe 601 in sprinkler structure 6 consists of a fixed pipe 6011 and a movable pipe 6012. When the sprinkler height needs to be adjusted, motor 607 starts, and the output shaft of motor 607 drives lead screw 606 to rotate. Lead screw 606 is threadedly connected to moving block 608, which slides in slide rail 605, thereby driving movable pipe 6012 to move up and down, realizing the adjustment of the height of telescopic pipe 601. The height of the sprinkler can be flexibly adjusted according to different growth stages of jujube trees or different terrain conditions to ensure that the mist evenly covers the jujube tree canopy. Water is sprayed out in the form of mist through impact nozzle 602, which improves the temperature and humidity environment of the jujube orchard canopy, alleviates the adverse effects of high temperature and low humidity on jujube tree pollination, and improves the fruit setting rate of jujube trees.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
