Description

Technical Field

[0001] This invention relates to the fields of landscape architecture and smart agriculture, and more specifically to a smart garden maintenance system with visual early warning and one-click repair functions. Background Technology

[0002] With the deepening development of smart city and digital living concepts, home gardening and villa courtyard maintenance are gradually entering the era of intelligence. Industry data shows a significant increase in demand for smart garden management systems, indicating huge market potential. Modern intelligent gardening systems typically rely on Internet of Things (IoT) technology, using sensors to collect soil temperature and humidity data and combining this with automatic sprinkler systems to achieve precise irrigation. This aims to solve problems such as water waste, uneven irrigation, and lack of real-time monitoring inherent in traditional irrigation methods.

[0003] However, existing intelligent maintenance systems still suffer from significant gaps in user experience and functional limitations.

[0004] First, current smart systems mostly focus on the collection and display of backend data, and users often need to rely on charts on mobile apps or computers to understand the status of their gardens. This "invisible" monitoring method lacks intuitive on-site feedback. When soil moisture is abnormal, the system usually only alerts remote users through pop-ups or sounds, failing to provide immediate physical warnings to on-site personnel, resulting in a lag in maintenance response.

[0005] Secondly, while some systems have implemented threshold-based automatic irrigation, they lack efficient "emergency" mechanisms in the face of sudden droughts or sensor data misinterpretations. Existing remote control operations are often cumbersome and lack closed-loop repair logic for mandatory execution, making it difficult to meet users' urgent need for "one-click problem solving."

[0006] In summary, while existing technical solutions have achieved basic automation, there is still room for improvement in terms of the intuitiveness of human-computer interaction (visual warning) and the convenience of emergency handling (one-click repair).

[0007] Therefore, there is an urgent need for an intelligent maintenance system that can visualize data status and simplify and enforce repair operations in order to improve the intelligence level of garden management and user experience. Summary of the Invention

[0008] In view of the above problems, the present invention is proposed to provide a smart garden maintenance system with visual early warning and one-click repair functions to overcome or at least partially solve the above problems. The system monitors soil data through sensors and links the light status (always on / flickering) to achieve intuitive early warning. It also achieves closed-loop maintenance by one-click forced irrigation through the web page until the data is restored.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] This invention provides a smart garden maintenance system with visual early warning and one-click repair functions, including: a detector sensor group, a sprinkler device, a lighting device, a smart electrical box, and a maintenance web terminal; The detector sensor group includes a soil temperature sensor and a soil moisture sensor; wherein, the probe end of the sensor is inserted into the soil, and the other end is connected to the smart electrical box. The sprinkler system and the lighting system are respectively connected to the smart electrical box; The intelligent electrical box is used to receive soil temperature and humidity data; when the soil temperature and humidity data are within a preset range, it controls the lighting device to remain on; otherwise, it controls the lighting device to flash as a visual alarm. The maintenance web terminal is used to interact with the smart electrical box and display soil temperature and humidity data. The maintenance web terminal is equipped with a "one-click repair" button, which, when triggered, forces the sprinkler irrigation device to start irrigation until the soil temperature and humidity data recovers to a preset threshold and then shuts down the sprinkler irrigation device.

[0011] Furthermore, the sprinkler irrigation device includes a water source interface, a solenoid valve, a main sprinkler pipe, and a sprinkler head. The solenoid valve is connected in series between the water source interface and the main sprinkler pipe, and the main sprinkler pipe is connected to the sprinkler head. The controller of the solenoid valve is connected to the smart electrical box.

[0012] Furthermore, the water source interface is a faucet, one end of the solenoid valve is connected to the faucet, and the other end is connected to the main irrigation pipe.

[0013] Furthermore, the lighting device includes landscape lights arranged in the garden, and the control circuit of the landscape lights is connected to the smart electrical box.

[0014] Furthermore, the intelligent electrical box has a built-in main control unit and a communication module. The main control unit is used to receive soil temperature and humidity data and control the solenoid valve of the sprinkler device and the operation of the landscape lights of the lighting device. The communication module communicates with the maintenance web terminal to realize data interaction.

[0015] Furthermore, the "one-click repair" button has the highest priority. When triggered, the system enters a high-frequency monitoring mode and forcibly starts the sprinkler device. When the sensor detects that the soil moisture has risen back to the preset threshold, the sprinkler device is automatically shut off and the flashing light alarm is deactivated.

[0016] Furthermore, the probe end of the sensor is inserted vertically into the soil to a depth of 10-15 centimeters.

[0017] Furthermore, the detector sensor group is connected to the smart electrical box via wired lines or wireless communication modules.

[0018] Furthermore, the lighting device flashes at a preset frequency during visual warning.

[0019] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a smart garden maintenance system with visual early warning and one-click repair functions, which has the following beneficial effects: This system achieves intuitive visualization and dual feedback of maintenance status: by linking a smart electrical box with a lighting device, abstract soil temperature and humidity data are transformed into intuitive light signals (solid light indicates normal operation, flashing indicates an alarm), solving the problems of "data invisibility" and reliance on backend monitoring in existing technologies. This visual early warning mechanism in physical space not only facilitates on-site personnel in instantly detecting anomalies but also enhances the technological feel and interactive experience of the garden environment.

[0020] An efficient emergency "first aid" closed-loop mechanism has been established: an innovative "one-click repair" function has been set up on the maintenance web terminal, giving this command the highest control priority. When the user triggers the button, the system forcibly starts the sprinkler system for deep irrigation until the sensor data recovers to the health threshold and then automatically stops. This mechanism breaks through the limitation of traditional remote control, which only acts as a "switch," and realizes an automated closed loop from "discovering the problem" to "completely solving the problem," effectively preventing plant damage caused by operational hesitation or cumbersome procedures.

[0021] It balances the dual needs of automated irrigation and aesthetic landscaping: the system integrates sprinkler irrigation and lighting devices on the same control platform, ensuring timely water replenishment when the soil is dry, while also utilizing the landscape lighting function of the lights themselves to beautify the courtyard environment during non-alarm periods. This single system achieves both "maintenance" and "landscaping" benefits, improving equipment utilization and cost-effectiveness.

[0022] This enhances the reliability and user-friendliness of intelligent gardening: the high-frequency monitoring mode and automatic shut-off logic of the main control unit ensure the safety of the "one-click repair" process and prevent over-irrigation; while the remote data interaction function of the web terminal allows users to monitor and intervene in the garden's status from anywhere. This "local visual early warning + remote forced repair" design greatly lowers the technical threshold for gardening maintenance and is suitable for various user groups. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] This invention discloses a smart garden maintenance system with visual early warning and one-click repair functions, referring to... Figure 1 As shown, it includes: a detector sensor group, a sprinkler system, a lighting system, a smart electrical box, and a maintenance web terminal; The detector sensor group includes a soil temperature sensor and a soil moisture sensor; the probe end of the sensor is inserted into the soil, and the other end is connected to the smart electrical box. The sprinkler system and lighting system are respectively connected to the smart electrical box; The intelligent electrical box is used to receive soil temperature and humidity data; when the soil temperature and humidity data are within the preset range, it controls the lighting device to stay on; otherwise, it controls the lighting device to flash as a visual alarm. The maintenance web terminal is used to interact with the smart electrical box and display soil temperature and humidity data. The maintenance web terminal is equipped with a "one-click repair" button, which, when triggered, forces the sprinkler irrigation device to start irrigation until the soil temperature and humidity data return to the preset threshold and then shuts off the sprinkler irrigation device.

[0027] This embodiment is applied to a private garden, where a smart garden maintenance system with visual early warning and one-click repair functions is deployed. The system includes a detector sensor group, a sprinkler device, a lighting device, a smart electrical box, and a maintenance web terminal. Its specific deployment structure and connection relationship are as follows.

[0028] 1. Detector sensor group.

[0029] The detector's sensor array includes soil temperature sensors and soil moisture sensors.

[0030] Representative monitoring points are selected within the garden. In this embodiment, areas near plant roots, without significant obstruction, and susceptible to environmental influences are chosen for the installation of soil temperature and humidity sensors. The specific procedure involves using a specialized drilling tool to vertically drill holes in the soil to a predetermined depth (10-15 cm in this embodiment) to ensure proximity to the main root layer of the plants. The probes of the soil temperature and humidity sensors are carefully inserted into the holes, and the soil is backfilled to ensure close contact between the probes and the soil for accurate data acquisition. The sensor signal lines are led out along the edge of the garden or through pre-buried underground pipes and connected to the signal input port of the smart electrical box. To ensure comprehensive monitoring, multiple sets of sensors can be deployed according to the garden area to form a grid-like monitoring network.

[0031] The soil moisture sensor in this embodiment uses a capacitive soil moisture sensor, such as FDS-100, RS485, SEN0193, or YL-69. These sensors are corrosion-resistant, provide stable measurements, and are suitable for long-term burial in the soil. The soil temperature sensor uses a waterproof type, DS18B20 or FS200-SHT30. The sensor's probe is inserted into the soil at the designed location, and the other end is connected to the controller in the smart electrical box via an RS485 wired line or a LoRa / ZigBee wireless module.

[0032] 2. Sprinkler irrigation system.

[0033] The sprinkler irrigation device in this embodiment refers to... Figure 2 As shown, it includes a water source interface, a solenoid valve, a sprinkler main pipe and a sprinkler head connected in sequence. The physical valve of the solenoid valve is connected in series between the water source interface and the sprinkler main pipe, and the controller of the solenoid valve is connected to the smart electrical box.

[0034] In this embodiment, the water source interface is a faucet, using a standard faucet (usually a 4-point or 6-point external thread interface), which is directly connected to the municipal tap water supply or water storage device on site. A solenoid valve is connected in series at the rear of the faucet for easy manual shut-off of the water supply for maintenance.

[0035] The solenoid valve is a normally closed plastic solenoid valve, with one end connected to the faucet and the other end connected to the main irrigation pipe. Its features include: Normally closed: The valve automatically closes in the event of a power outage, preventing continuous leakage due to system power failure or controller malfunction. Plastic valve body: Lightweight, corrosion-resistant, suitable for humid garden environments, and less expensive than metal valves. Operating voltage: Commonly DC 12V or AC 24V, offering high safety and compatibility with low-voltage control signals output from the smart control box. The solenoid valve's inlet connects to the faucet outlet via a threaded adapter, and the outlet connects to the main irrigation pipe. Two control wires from the solenoid coil connect to the normally open contacts of the relay module within the smart control box.

[0036] The main sprinkler pipe uses PE or PVC water supply pipes, typically with a diameter of Φ16mm or Φ20mm. PE pipes are flexible and can be bent for laying, making them suitable for gardens with undulating terrain; quick-connect fittings facilitate installation. PVC pipes are more rigid, suitable for straight-line burial, and have high pressure resistance. In this embodiment, the main sprinkler pipe is arranged along the garden terrain, branching to various sprinklers or drippers, and a flushing ball valve is installed at the end for wastewater discharge.

[0037] The sprinkler head is selected based on the plant type, and can be either an adjustable-angle micro-sprinkler or a pressure-compensating dripper. The adjustable-angle micro-sprinkler is suitable for large-area, uniform irrigation of lawns, flower beds, and ground cover plants. It allows adjustment of the spray radius (0.5–3 meters) and fan angle (0°–360°), producing a fine, even mist. The pressure-compensating dripper is suitable for shrubs, trees, potted plants, or plants requiring precise water conservation. It maintains a constant water output within a certain pressure fluctuation range, preventing water shortages at higher or farther locations and excessive watering at lower locations. In this embodiment, the sprinkler head connects to the main pipe via branch capillary tubes (Φ4mm or Φ6mm). An anti-drip valve or filter can be installed before each sprinkler head to prevent clogging.

[0038] 3. Lighting fixtures.

[0039] The lighting device in this embodiment includes several LED landscape lights arranged in the garden landscape, and the control circuit of the lighting device is connected to a smart electrical box.

[0040] The LED landscape lights in this embodiment are DC 12V / 24V LED in-ground lights or RGB tree lights to ensure safety for personnel (especially suitable for humid garden environments). Common types include: LED in-ground lights: Waterproof rating ≥ IP67, can be embedded in the ground or paved surface, used to illuminate paths, plant roots, or flower bed edges. Light color options include warm white, cool white, or monochrome.

[0041] RGB tree lights: such as the LiteYear LY-DMD-12W, support red, green and blue three-color mixing and can achieve a variety of color changes through PWM dimming. They are used to illuminate trees or shrubs upwards to enhance the layering of the nighttime landscape.

[0042] The power of the lamps is selected according to the installation height and illumination area, usually 3W-12W. Multiple lamps can be connected in parallel to the same control circuit.

[0043] When soil moisture and temperature are within the preset healthy threshold range, such as moisture 30%–60% and temperature 5°C–35°C, the main control unit controls the relay to close, keeping the LED landscape lights constantly on as the basic nighttime lighting for the garden. The RGB lights can be set to warm yellow-white light or user-defined static colors.

[0044] When any sensor value exceeds a threshold, such as when soil moisture drops below 25%, a severe drought alarm is triggered. The main control unit immediately intervenes and controls the corresponding area's lighting circuit to enter flashing mode. The typical flashing frequency is 1 second on – 1 second off, or 0.5 seconds on – 0.5 seconds off, to attract the attention of on-site personnel. The RGB lights can simultaneously switch to red or amber while flashing to enhance the warning effect.

[0045] 4. Intelligent electrical box.

[0046] The intelligent electrical box has a built-in main control unit and communication module. The main control unit is used to receive soil temperature and humidity data and control the operation of solenoid valves and landscape lights. The communication module communicates with the maintenance web terminal to realize data interaction.

[0047] The main control unit in this embodiment uses a microcontroller, such as RP2350-Zero, ESP32, STM32F103, Arduino Mega 2560, etc., to receive data uploaded by the soil temperature and humidity sensor and control the operation of the solenoid valve and LED landscape lights according to preset logic.

[0048] The communication module connects to the main control unit and supports WiFi, Ethernet, or 4G communication methods. It is responsible for bidirectional data interaction with the maintenance web terminal. The communication module uploads sensor data to the cloud or local server and simultaneously receives control commands from the web terminal.

[0049] The main control unit has preset threshold parameters for normal plant growth, including upper and lower limits for soil moisture and soil temperature. Users can remotely modify these thresholds through a web-based maintenance terminal to adapt to different plant species or seasonal changes.

[0050] The main control unit inside the intelligent electrical box compares sensor data with preset thresholds for normal plant growth in real time. When plant parameters such as soil temperature and humidity are within normal ranges, the main control unit keeps the LED landscape lights constantly on for landscape lighting. When any parameter exceeds the normal threshold, such as severe water shortage, the main control unit controls the LED landscape lights to flash, providing a direct visual warning signal on-site. The flashing frequency can be adjusted as needed.

[0051] This embodiment deeply integrates sensor data with on-site landscape lighting. The main control unit compares safety thresholds in real time: when the data is normal, the lights remain on to ensure adequate nighttime illumination; when the data is abnormal, the lights immediately flash as an alarm. This design achieves zero-latency on-site early warning with "seeing the lights and knowing their status," and gives the landscape a vivid and interactive technological effect.

[0052] 5. Maintain the web terminal.

[0053] The maintenance web terminal in this embodiment runs on a PC, tablet, or mobile phone browser and interacts bidirectionally with the communication module inside the smart electrical box via the Internet or local area network. The terminal provides a data monitoring page and a control page (which can be integrated into a single page) for displaying real-time soil temperature and humidity data, issuing control commands, and receiving system alarm information.

[0054] The maintenance web terminal and the smart electrical box exchange data using the MQTT protocol (recommended) or HTTP RESTful API. The smart electrical box, acting as a publisher / client, periodically reports sensor data and equipment status; the web terminal, acting as a subscriber / client, receives and displays this data in real time.

[0055] The webpage displays soil moisture (%) and soil temperature (°C) for each sensor location using dashboards, line graphs, and numerical cards. It also shows information such as device online / offline status, last data update time, and threshold settings.

[0056] When any sensor data exceeds the preset threshold, the corresponding point card on the page is highlighted in red, and an "abnormal" icon or text prompt appears, forming a double warning along with the flashing lights on site.

[0057] The maintenance web terminal features a "One-Click Repair" button. When the user clicks this button, the web terminal immediately sends a forced-open solenoid valve command to the smart control box via MQTT or HTTP POST. This command has the highest control priority, overriding any automatic timed irrigation plan or manual setting, ensuring timely emergency response. Upon triggering, the sprinkler system is forcibly activated for irrigation until soil temperature and humidity data return to the preset threshold, at which point the sprinkler system shuts off. When the sensor detects that soil temperature and humidity have risen back to the preset threshold, the sprinkler system is automatically shut off, and the flashing alarm light is deactivated.

[0058] To avoid accidental operation, a secondary confirmation dialog box can pop up after clicking (for example: "Confirm to start emergency irrigation? The system will automatically stop after the soil moisture recovers."). You can only execute the operation after confirming.

[0059] The maintenance website features a groundbreaking "One-Click Repair" button with the highest control priority. Clicking it triggers the system to immediately activate the solenoid valve for irrigation and simultaneously enter a high-frequency monitoring automatic closed-loop mode. Once the sensor detects that soil moisture has returned to a healthy threshold, the system automatically shuts off the water valve and stops the flashing lights. This transforms complex professional maintenance into a precise, "one-click" emergency response, saving time, effort, and water.

[0060] This embodiment realizes a smart garden maintenance system that integrates soil environment monitoring, visual status feedback, cloud data management, and rapid response irrigation.
