Abstract
Description
Technical Field
[0001] This invention relates to the field of automated drip irrigation technology, specifically to an easy-to-operate automated drip irrigation system and equipment. Background Technology
[0002] With global population growth and accelerated industrialization, water resources are becoming increasingly scarce. Traditional irrigation methods (such as flood irrigation and sprinkler irrigation) often waste a large amount of water, while drip irrigation systems, through precise water flow control, greatly improve water resource utilization efficiency. Modern agriculture pursues high efficiency, precision, and sustainable development. Automated drip irrigation systems can provide precise irrigation based on soil moisture, climate conditions, and crop needs, improving crop yield and quality while reducing environmental impact. The development of modern technologies such as sensor technology, microelectronics technology, communication technology, and big data analysis provides strong technical support for the research and application of automated drip irrigation systems. These technologies enable drip irrigation equipment to achieve intelligent, remote control, and data analysis functions. To address water scarcity and promote sustainable agricultural development, many countries and regions have introduced a series of policies and measures to encourage and support the research and promotion of water-saving irrigation technologies such as drip irrigation. Therefore, this paper proposes a simple-to-operate automated drip irrigation system and equipment.
[0003] In existing technologies, drip irrigation systems are mainly divided into two categories: one is a high-cost, fully automated system that monitors farmland humidity in real time and automatically controls the drip irrigation system to irrigate the farmland; the other is the most basic drip irrigation system, which is operated manually, with farmers relying on their experience to control the irrigation volume. For medium-sized farmers, the former is too costly and difficult to promote, while the latter cannot provide precise irrigation based on farmland conditions, affecting the drip irrigation effect. Therefore, this paper proposes a simple-to-operate automated drip irrigation system and equipment. On the traditional drip irrigation technology, a controller is added to the water pump, and a humidity testing device is set at the terminal according to user needs. Users can set the required humidity value, and when the humidity is lower than the set value, the water pump automatically starts drip irrigation, thereby achieving automated irrigation of farmland at a lower cost, meeting the needs of some medium-sized farmers, avoiding over-irrigation and water waste, and improving water resource utilization efficiency. Summary of the Invention
[0004] To address the shortcomings of existing technologies, such as high costs and inability to provide precise irrigation tailored to farmland conditions, this invention offers a simple-to-operate automated drip irrigation system and equipment, which boasts the advantages of low-cost automated irrigation and improved water resource utilization efficiency.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a simple-to-operate automated drip irrigation system, the modules of which include:
[0006] A power management module that provides power to the entire drip irrigation system;
[0007] The controller module is responsible for the central control and decision-making of the system, and has preset programs to control the operation of each piece of equipment.
[0008] A drip irrigation pipeline and dripper management module for distributing and controlling irrigation water flow to the crop root zone;
[0009] A filter management module used to prevent impurities in irrigation water from clogging drippers and to ensure the normal operation of the irrigation system;
[0010] Equipment detection alarm module used to monitor the working status of each device in the system, detect faults in a timely manner and issue alarm signals;
[0011] A data recording and transmission module that records system operation data, including irrigation time, water volume, pressure, and humidity, and remotely transmits it to the user terminal;
[0012] The controller module includes a water pump drive module for providing pressure to transport water from the water source to the drip irrigation pipeline; the drip irrigation pipeline and dripper management module includes an electric valve management module for controlling the on / off of irrigation water to achieve zoned irrigation and timed irrigation; and the equipment detection and alarm module includes a humidity sensor module for real-time monitoring of soil moisture.
[0013] The power management module is based on a switching power supply UPS device, with voltage regulation and overload protection circuits to ensure power stability and safety. The controller module is based on a hardware Arduino development board, a humidity sensor (DHT), solenoid valves and relays, a motor driver and a water pump, and a wireless communication device (Wi-Fi Shield). The data line of the humidity sensor is connected to the analog input pin of the Arduino, the signal line of the electric valve control module is connected to the digital output pin of the Arduino, and the control line of the water pump is connected to the digital output pin of the Arduino. The wireless communication device (Wi-Fi Shield) is then connected to the Arduino according to the corresponding tutorial to achieve control.
[0014] The water pump control module connects the input of the motor driver to the PWM output pin of the Arduino based on the controller module, and connects the output of the motor driver to the motor of the water pump using digital pins. First, a variable is defined to represent the PWM pin controlling the water pump. Then, in the setup function, the PWM output is initialized, and the target speed is calculated based on the sensor readings. In Arduino, the PWM value range is -1, where 1 represents completely off and 2 represents full speed operation. The analogWrite function is used to set the PWM value to the calculated target speed to change the motor speed. Finally, the system determines whether irrigation is needed. If irrigation is needed, the water pump is turned on and the speed is set; otherwise, the water pump is turned off.
[0015] The electric valve management module in the drip irrigation pipeline and dripper management module connects the output terminals of the drip irrigation pipeline and dripper to the water pump motor based on the controller module. First, a variable is defined to represent the pin controlling the electric valve. In the setup function, the valve control pin is initialized to output mode and set to the closed state. A real-time clock module DS is added and initialized in the setup function, and the current date and time are set to achieve timed irrigation. According to the current irrigation area and region, the corresponding valve is opened and closed simultaneously through the digitalWrite function. The real-time clock module is used to obtain the current time and compare it with the preset irrigation time. When the current time reaches the preset irrigation time, the valve is opened through the digitalWrite function to start irrigation, achieving timed irrigation. After a preset irrigation duration delay, the valve is closed through the digitalWrite function. Finally, the code is written and compiled using the Arduino IDE and uploaded to the Arduino development board to implement the valve control of the drip irrigation pipeline and dripper.
[0016] The filter management module sets a threshold X for pressure difference and flow reduction. When the pressure exceeds the threshold X, it indicates that the filter needs to be cleaned or replaced. The upstream valve is opened to allow water to flow into the filter. The working status of the filter is monitored by pressure and flow sensors. If the pressure difference and flow reduction do not exceed the preset threshold, the filter continues to work normally. If the pressure difference and flow reduction exceed the preset threshold, it indicates that the filter has a problem with blockage and reduced efficiency. The upstream valve is closed to stop the water flow into the filter for replacement and cleaning.
[0017] The device detection and alarm module monitors the status parameters of the humidity sensor, including voltage, current, temperature, and humidity. It uses a moving average method to remove noise from the monitoring data. Based on the moving average method:
[0018] New_Value=(Old_Value*(N-1)+New_Measurement) / N
[0019] Where Old_Value is the smoothed value from the previous moment, New_Measurement is the current measured value, and N is the window size. Based on the normal operating range of the equipment and the requirements for fault early warning, upper and lower limit thresholds X and Y are set. The relationship between the measured value Z and the threshold values X and Y is compared to see if the limits are exceeded. If the measured value exceeds the set threshold range, the equipment is considered to be abnormal. Different levels of alarm thresholds and response methods are set according to the severity of the fault. An alarm is triggered when multiple consecutive measured values exceed the threshold or when a single measured value exceeds the severe fault threshold. The number of consecutive exceedances is calculated as follows:
[0020] Continuous_Exceed_Count=Σ(Threshold_Check_Result)
[0021] Threshold_Check_Result is the sum of the results of each measurement value compared with the threshold. If the limit is exceeded, the alarm triggering condition is met and an alarm signal is generated, which includes LED flashing, buzzer sounding, SMS notification, and email notification. The alarm time, equipment status parameters, and alarm level information are recorded through the data recording and transmission module.
[0022] The data recording and transmission module collects relevant data from various modules based on the data logger, performs preliminary processing on the collected data, including filtering and noise reduction, and data conversion to convert analog signals into digital signals. Then, the collected data is stored in the memory buffer of the microcontroller. Finally, a certain number of data are packaged into a data packet, each data packet containing a timestamp, device identifier, and data type additional information, and the storage medium is selected from internal flash memory, external SD card, or cloud storage.
[0023] Equipment corresponding to a simple-to-operate automated drip irrigation system;
[0024] The automated drip irrigation equipment includes an irrigation body for controlling and managing the irrigation process and a water pump for providing sufficient pressure to deliver water from the water source to the irrigation outlet.

[0038] Equipment detection alarm module 5 is used to monitor the working status of each device in the system, detect faults in a timely manner and issue alarm signals.
[0039] The data recording and transmission module 6 records the system's operational data, including irrigation time, water volume, pressure, and humidity, and remotely transmits it to the user terminal.
[0040] The controller module 2 is equipped with a water pump drive module 7 for providing pressure to transport water from the water source to the drip irrigation pipeline; the drip irrigation pipeline and dripper management module 3 is equipped with an electric valve management module 8 for controlling the on and off of irrigation water to realize zoned irrigation and timed irrigation; and the equipment detection and alarm module 5 is equipped with a humidity sensor module 9 for real-time monitoring of soil moisture.
[0041] Power management module 1 is based on a switching power supply UPS device, with voltage regulation and overload protection circuits to ensure power stability and safety. Controller module 2 is based on an Arduino development board, a DHT11 humidity sensor, solenoid valves and relays, a motor driver and a water pump, and a Wi-Fi Shield wireless communication device. Connect the humidity sensor's data line to the Arduino's analog input pin, the electric valve control module's signal line to the Arduino's digital output pin, and the water pump's control line to the Arduino's digital output pin. Use the Wi-Fi Shield wireless communication device to connect to the Arduino according to the corresponding tutorial to achieve control.
[0042] The water pump control module 7 connects the input of the motor driver to the PWM output pin of the Arduino based on the controller module 2. Digital pins 3, 5, 6, 9, 10, and 11 are used to connect the output of the motor driver to the water pump motor. First, a variable is defined to represent the PWM pin controlling the water pump. Then, in the setup function, the PWM output is initialized, and the target speed is calculated based on sensor readings. In Arduino, the PWM value ranges from 0 to 255, where 0 represents completely off and 255 represents full speed operation. The analogWrite function is used to set the PWM value to the calculated target speed to change the motor speed. Finally, the system determines whether irrigation is needed. If irrigation is needed, the water pump is turned on and the speed is set; otherwise, the water pump is turned off.
[0043] The electric valve management module 8 in the drip irrigation pipeline and dripper management module 3 connects the output terminals of the drip irrigation pipeline and drippers to the water pump motor based on the controller module 2. First, a variable is defined to represent the pin controlling the electric valve. In the setup function, the valve control pin is initialized to output mode and set to the closed state. A real-time clock module DS1307 is added and initialized in the setup function, and the current date and time are set to realize timed irrigation. According to the current irrigation area 1 and area 2, the corresponding valve is opened and closed simultaneously through the digitalWrite function. The real-time clock module is used to obtain the current time and compare it with the preset irrigation time. When the current time reaches the preset irrigation time, the valve is opened through the digitalWrite function to start irrigation, realizing timed irrigation. After a preset irrigation duration delay, the valve is closed through the digitalWrite function. Finally, the Arduino IDE is used to write and compile the code, and the compiled code is uploaded to the Arduino development board to realize the valve control of the drip irrigation pipeline and drippers.
[0044] The filter equipment management module 4 sets the threshold X for pressure difference and flow reduction. When the pressure exceeds the threshold X, it indicates that the filter equipment needs to be cleaned or replaced. The upstream valve is opened to allow water to flow into the filter equipment. The working status of the filter equipment is monitored by pressure and flow sensors. If the pressure difference and flow reduction do not exceed the preset threshold, the filter equipment continues to work normally. When the pressure difference and flow reduction exceed the preset threshold, it indicates that the filter equipment has problems with blockage and reduced efficiency. The upstream valve is closed to stop the water flow into the filter equipment for replacement and cleaning.
[0045] Equipment detection and alarm module 5 monitors the status parameters of equipment (voltage, current, temperature, and humidity) from humidity sensor 9. It uses a moving average method to remove noise from the monitoring data. (Based on the moving average method:)
[0046] New_Value = (Old_Value) * (N-1)+New_Measurement) / N
[0047] Where Old_Value is the smoothed value from the previous moment, New_Measurement is the current measured value, and N is the window size. Based on the normal operating range of the equipment and the requirements for fault early warning, upper and lower limit thresholds X and Y are set. The relationship between the measured value Z and the threshold values X and Y is compared to see if the limits are exceeded. If the measured value exceeds the set threshold range, the equipment is considered to be abnormal. Different levels of alarm thresholds and response methods are set according to the severity of the fault. An alarm is triggered when multiple consecutive measured values exceed the threshold or when a single measured value exceeds the severe fault threshold. The number of consecutive exceedances is calculated as follows:
[0048] Continuous_Exceed_Count=Σ(Threshold_Check_Result)
[0049] Threshold_Check_Result represents the result of each measurement comparison with the threshold (0 or 1). 1 indicates that the limit has been exceeded, and the alarm triggering condition is met to generate an alarm signal, which includes LED flashing, buzzer sounding, SMS notification, and email notification. The alarm time, equipment status parameters, and alarm level information are recorded by the data recording and transmission module 6.
[0050] The data recording and transmission module 6 collects relevant data from various modules based on the data logger, performs preliminary processing on the collected data, including filtering and noise reduction, and data conversion to convert analog signals into digital signals. Then, the collected data is stored in the memory buffer of the microcontroller. Finally, a certain amount of data is packaged into a data packet, each data packet containing a timestamp, device identifier, data type additional information, and the storage medium is selected from internal flash memory, external SD card, or cloud storage.
[0051] Among them, controller module 2 is responsible for receiving and processing various input signals, as well as controlling the operation of the system.
[0052] The humidity sensor module 9 consists of multiple distributed humidity sensors for real-time monitoring of soil moisture. The data is wirelessly transmitted to the controller module 2 via the data recording and transmission module 6. Users can remotely monitor and control the irrigation process by accessing the controller module 2 through remote communication between their smartphones or tablets. The water pump drive module 7 controls the water pump to provide the water pressure required for irrigation.

The electric valve management module 8 automatically controls the opening and closing of the valve based on the data from the humidity sensors and the preset irrigation plan to achieve precise irrigation. Water is delivered from the water source to the plant roots through the irrigation pipe head. The dripper head is designed with tiny water outlet holes to ensure that the water drips into the soil evenly and slowly.

A filter head controller 17 is fixedly installed on the outside of the end of the irrigation water pipe 16 away from the water outlet valve 18.
[0055] The humidity sensor 15 is installed in the soil via a humidity sensor line 14 to monitor soil moisture in real time and transmit the data to the controller in the system. The controller determines whether irrigation is needed based on a preset humidity threshold and irrigation plan. When irrigation is needed, the controller starts the water pump 11 to deliver water from the source to the irrigation pipe 16. The tiny water outlet on the irrigation pipe 16 drips water according to a preset flow rate and time. The water outlet valve 18 is installed on the irrigation pipe to manually or automatically control the water flow. Finally, the water is filtered by the filter head controller 17 before irrigation.
