[0063] The installation method and workflow of the intelligent drip irrigation system for highway slope maintenance provided in the embodiment of the present application include:

[0064] 1. Equipment Installation and Commissioning: First, ensure that all drip irrigation system components (such as the water tank, booster pump, level switch, flow meter, smart meter, soil temperature and humidity sensor 18, filter 3, outlet valve, three-way valve, drip irrigation pipe, etc.) are installed and connected correctly according to design requirements. The photovoltaic power generation system must also be installed on the highway slope to ensure sufficient sunlight.

[0065] 2. Intelligent drip irrigation system startup process:

[0066] (1) Monitoring soil temperature and humidity: The soil temperature and humidity sensor 18 monitors the temperature and humidity of the slope soil in real time. These data are transmitted to the PLC controller 19 via RS485 communication.

[0067] (2) Intelligent control strategy:

[0068] ① Setpoint Condition: When soil temperature and humidity fall below setpoints, the PLC controller 19 activates the intelligent drip irrigation system based on its built-in automatic drip irrigation algorithm. Based on real-time soil condition data, the system precisely controls the pump's operating time, frequency, and valve opening to ensure proper irrigation of vegetation while minimizing energy consumption.

[0069] ② Periodic drip irrigation mode: When the soil temperature and humidity are within the set range, the system switches to periodic drip irrigation mode. In this mode, the drip irrigation system irrigates at preset time intervals to keep the soil moderately moist.

[0070] ③Alarm Processing: When soil temperature and humidity exceed the set alarm threshold, the system enters energy storage mode and stops drip irrigation to prevent over-irrigation and water waste. Simultaneously, the system sends an alert to relevant personnel via the cloud platform, indicating that the soil may be too wet and requiring adjustments to the drip irrigation strategy or other management measures.

[0071] 3. Optimization and adjustment:

[0072] Cloud Platform Data Analysis: Real-time data collected is transmitted to the cloud platform via an intelligent gateway for verification and analysis with meteorological bureau data. Big data computing and deep learning technologies are used to optimize the drip irrigation system's control strategy. The system's operating mode and parameter settings are dynamically adjusted based on the climate characteristics and soil conditions of different regions to maximize water resource utilization efficiency and the health of slope vegetation.

[0073] Through the above work process, this application realizes the intelligent management of highway slope maintenance, fully utilizes modern technical means, ensures stable system operation, efficient resource utilization, and can effectively adapt to and operate under various climatic conditions.

[0074] In summary, compared to existing technologies, the system provided by this application integrates devices such as liquid level switches, flow meters, smart meters, and soil temperature and humidity sensors. The system can monitor water tank liquid levels, water flow, power consumption, and slope soil temperature and humidity in real time. This data is transmitted back to the PLC controller via RS485 communication and analyzed and processed by intelligent algorithms. This intelligent monitoring and control system ensures the stability and reliability of drip irrigation, while optimizing water resource utilization and reducing energy costs.

[0075] The system proposed in this application uses a solar photovoltaic power generation system to provide a stable power supply for the drip irrigation system, solving the power supply problem commonly encountered in traditional highway slope maintenance. This green energy source not only reduces the system's operating costs but also reduces its dependence on the traditional power grid, offering environmentally friendly and sustainable development advantages.

[0076] The system provided in this application transmits field-collected data to a cloud platform via an intelligent gateway, enabling integration and verification with meteorological bureau data. The cloud platform utilizes big data computing and deep learning technologies to develop optimized drip irrigation control strategies based on the climate conditions and soil characteristics of different regions. This locally tailored control strategy can effectively improve water resource utilization efficiency, minimize water waste, and ensure the proper growth and health of vegetation under different climate conditions.

[0077] In summary, the technical solution of this application achieves comprehensive optimization of the intelligent drip irrigation system on highway slopes through the application of sensor technology, the utilization of solar power generation systems, and cloud platform data analysis and optimization. It not only improves the automation and stability of the system, but also significantly reduces operating costs, which meets the needs of modern highway maintenance and environmental protection concepts.
