Description
Technical Field
[0001] This invention belongs to the field of water spray control technology, specifically relating to a water-saving water spray control device for garden water utilization. Background Technology
[0002] Spraying water is a technical measure to supplement the water needed by crops. In order to ensure the normal growth of crops and obtain high and stable yields, crops must be supplied with sufficient water. Under natural conditions, the water requirements of crops are often not met due to insufficient rainfall or uneven distribution. Therefore, it is necessary to spray water artificially to make up for the lack of natural rainfall. In garden construction, it is necessary to spray water on various plants frequently to ensure their normal growth. In garden construction, water spraying devices are mostly started manually, and the water pumps are then started manually. The water spraying time is determined by experience and habit, rather than by the condition of the plants. This is not only wasteful of water resources, but also detrimental to plant growth. Summary of the Invention
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a garden water utilization water-saving spray control device, including a garden spray controller and a wireless sensor node; The garden sprinkler controller includes a wireless communication module, a micro-sprinkler control valve, and a human-machine interface, which is responsible for receiving and transmitting operation commands and processing temperature and humidity information collected by wireless sensor nodes. The wireless sensor node includes a main control module, a sensor module, and a wireless communication module. It collects the temperature and humidity values of the garden soil and transmits the data wirelessly to the garden sprinkler controller. After the system starts, the garden sprinkler controller first initiates a network command. After receiving the response command from the wireless sensor node, the user sets various parameters through the host computer software. The sensor node periodically collects the temperature and humidity data of the entire garden soil and sends the data to the sprinkler controller so that it can take corresponding control strategies.
[0004] Furthermore, the sensor node consists of four parts: a power supply, a soil temperature and humidity sensor, and a Zigbee system-on-a-chip CC2430. The sensor module is used for information acquisition and data conversion within the garden; the processor module is used to control the operation of the entire sensor, receive and process the data it acquires, and data sent from other nodes; the wireless communication module is used for wireless communication with other sensor nodes and for transmitting and receiving acquired data; and the power supply module provides the necessary energy for the entire system.
[0005] Furthermore, the ZigBee chip used is the CC2430, which integrates the ZigBee RF front-end, memory, and microcontroller on a single chip; it uses an 8-bit MCU with 128KB of programmable flash memory and 8KB of RAM.
[0006] Furthermore, the garden sprinkler controller consists of a wireless data transmission module, a button input module, a control information I / O port output module, and a main control chip module. The microprocessor uses an MSP430F2274 microcontroller. The general-purpose I / O ports of the microprocessor are optically isolated from the solenoid valves. Each I / O port controls one solenoid valve to control the opening and closing of the micro-sprinkler head, and the opening time of the solenoid valve is controlled by a timer.
[0007] The beneficial effects of this invention include: This invention provides a water-saving sprinkler control device for garden water utilization, including a garden sprinkler controller and wireless sensor nodes. The garden sprinkler controller includes a wireless communication module, a micro-irrigation control valve, and a human-machine interface, responsible for receiving and transmitting operation commands and processing temperature and humidity information collected by the wireless sensor nodes.

[0010] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0011] like Figure 1As shown, this invention discloses a water-saving sprinkler control device for garden water utilization, including a garden sprinkler controller and wireless sensor nodes. The garden sprinkler controller includes a wireless communication module, a micro-irrigation control valve, and a human-machine interface, responsible for receiving and transmitting operation commands and processing temperature and humidity information collected by the wireless sensor nodes. The wireless sensor node includes a main control module, a sensor module, and a wireless communication module. Its function is to collect the temperature and humidity values of the garden soil and transmit the data wirelessly to the garden sprinkler controller. After the system starts, the garden sprinkler controller first initiates a network command, and upon receiving a response command from the wireless sensor node, the user sets various parameters through the host computer software. The sensor node periodically collects the temperature and humidity data of the entire garden soil and sends the data to the sprinkler controller for it to take corresponding control strategies. The design of the sensor node, the garden sprinkler controller, and the fuzzy control algorithm for temperature and humidity are described in detail.
[0012] The sensor nodes are responsible for collecting, receiving, and transmitting data on the soil temperature and humidity in the garden. The node structure is as follows: Figure 1 As shown, the node consists of four parts: a power supply, a soil temperature and humidity sensor, and a Zigbee system-on-a-chip CC2430. The sensor module is responsible for collecting and converting information within the garden; the processor module is responsible for controlling the operation of the entire sensor system, receiving and processing the data it collects, and data sent from other nodes; the wireless communication module is responsible for wireless communication with other sensor nodes and for transmitting and receiving collected data; and the power supply module provides the necessary energy for the entire system.
[0013] The sensor node is powered by two dry cell batteries (1.5V each), which is equivalent to using solar power. This also helps to reduce the size of the node. The batteries are recharged every six months, which is both economical and environmentally friendly.
[0014] The ZigBee chip used in this system is the Chipcon CC2430, which uses the same architecture as the previous CC2420 chip, integrating the ZigBee RF front-end, memory, and microcontroller on a single chip. It uses an 8-bit MCU (8051) with 128KB of programmable flash memory and 8KB of RAM, and also includes a 14-bit analog-to-digital converter (ADC), a wide voltage range (2.0~3.6V), several timers, a sleep-mode timer with a 32kHz crystal oscillator, a power-on reset circuit, and 21 programmable I / O pins. The CC2430 chip is low-power, powerful, and features a wide voltage range (2.0~3.6V). It integrates a 2.4GHz PF radio transceiver compliant with the IEEE 802.15.4 standard, requiring very few external components to achieve signal transmission and reception.
[0015] The selection and parameters of the humidity sensor: The basic workflow of this system using the TDR-3A sensor node mainly includes power-on initialization, data acquisition, power module operation, and data reception and transmission. When the system powers on and starts up, the program configures each port; the basic workflow is as follows... Figure 2 As shown The garden fountain controller consists of a wireless data transmission module, a button input module, a control information I / O port output module, and a main control chip module. The structure diagram is shown below. Figure 3 As shown. The microprocessor uses the MSP430F2274 microcontroller, a 16-bit microcontroller from TI's 430 family. It operates within a voltage range of 1.8–3.6V and boasts a performance of up to 16 MIPS. Normal operating power consumption is as low as 270uA. It features 10-bit AD sampling, 32KB of flash memory, and 1KB of RAM, making it a high-performance 430 microcontroller. The microprocessor's general-purpose I / O ports are optocoupled to the solenoid valves. Each I / O port controls one solenoid valve to control the opening and closing of the micro-spray nozzle. A timer controls the valve's opening time, and the system also offers high scalability.
[0016] The water requirement of forest crops is related to soil moisture content, air temperature, crop type, and growth stage. Soil moisture content and temperature values are obtained using a TDR-3A sensor, measuring the ambient temperature x∈[0,40] and soil moisture y∈[20%,55%]. The micro-irrigation time t is selected as the output.
[0017] Three fuzzy subsets are selected for temperature: low temperature, medium temperature, and high temperature, covering the universe of discourse [0,40] of input x; corresponding soil moisture content is divided into low moisture content, moderate moisture content, and high moisture content, covering the universe of discourse [20%,55%] of input y.
[0018] The fuzzy control algorithm for temperature and humidity in the system takes soil temperature and humidity values as input signals and outputs the timing of garden watering. First, the precise values of the input variables are converted into fuzzy linguistic variable values on an appropriate domain. The system then performs "archiving" fuzzy quantization on the state variable {e(k)}. The system's input variables, including the error e, rate of change ec, and output, all have corresponding ranges. When the value of e(k) exceeds the maximum error, the maximum error value is used. Similarly, the rate of change of the variable is calculated using the fuzzy method. Finally, the system determines the appropriate watering time based on the soil temperature and humidity values, thus achieving the spatiotemporal variability and efficient water resource utilization required for precision gardening.
[0019] The device is characterized by high flexibility, safety, reliability, and low power consumption. It requires no manual operation, eliminating the hassle and potential risks of wired connections, and can operate stably for extended periods, complementing wired control methods. Furthermore, the software utilizes a fuzzy control algorithm based on temperature and humidity for garden sprinkler systems, enhancing system reliability and practicality, and improving the usability of garden control systems and the efficiency of sprinkler irrigation. Wireless sensor networks not only have applications in gardening and agriculture, such as sensor data collection, water meter reading, and remote control of solenoid valves, but also hold broad promise for other fields such as home automation, automatic meter reading, and remote monitoring.
[0020] Micro-jet spraying is performed under certain pressure conditions (2×10). 5 Water is sprayed out in a mist form from the micro-holes on the upper side of the micro-spraying strips arranged between the plant rows (approximately Pa). The micro-spraying system used in the micro-spraying experiment demonstration consists of one main pipe and 3 to 5 branch pipes. The main pipe has a diameter of 80 mm, the branch pipes have a diameter of 40 mm, and micro-spraying holes with a diameter of 0.3 mm are distributed on the branch pipes. The hole spacing is 40 mm, the hole direction is "S" shaped, the water mist height is 1.4 to 1.6 m, and the spray width is 3 to 4 m. Micro-spraying has the following characteristics: (1) Maintaining soil physical properties. Compared with traditional furrow irrigation, micro-spraying plants have less soil compaction, lower bulk density, higher porosity, and better soil structure. (2) Saving water. Experiments show that the irrigation quota for micro-spraying is 240 to 360 m³ per hectare per spray. 3 (24~36mm), saving 50%~60% of water per hectare compared to conventional spraying. (3) Saves labor and land. Micro-spraying can reduce the labor required for spraying management by 60% and reduce the land used for ditches by 5%~10%. (4) Reduces pests and diseases and natural disasters. Since micro-spraying has no runoff, it reduces the chance of soil-borne diseases spreading and infecting, and can control aphids and caterpillars, greatly reducing the damage caused by pests and diseases. (5) Easy to control irrigation volume and achieve precise spraying. Micro-spraying can effectively control the amount of irrigation water. According to the water demand pattern of plants for high-quality and stable yield, different irrigation volumes can be set at different times for quantitative spraying. In particular, the water demand is small during the root extension period of plants, and the growth center is the underground root system. The irrigation volume should not be too large. Excessive irrigation will not only affect the root development, but also cause the soil temperature to drop, inducing the occurrence and spread of mosaic disease. (6) Timely irrigation and high uniformity. Spraying speed is fast, and micro-spraying of the covered tobacco field can be completed in 0.5~1.0h. Because it relies on micro-sprinklers for water delivery, it is not limited by terrain and can ensure the uniformity of irrigation across the entire field. It is particularly suitable for hilly areas and can avoid soil erosion and uneven drought and flooding caused by furrow irrigation. (7) Lower cost. Each micro-sprinkler system can cover 0.67 hm² by being moved. 2 (8) Improve the microclimate in the field and prevent sunburn damage.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
