The Automatic Sprinkler Irrigation System for Municipal Green Belts

The following is a comprehensive analysis of the technical key points, design specifications, and practical applications of the automatic sprinkler irrigation system for municipal green belts.

I. Core Technologies and Design Features of the System

Intelligent Control and Sensing Technology

Modern automatic sprinkler irrigation systems for municipal green belts generally adopt the Internet of Things (IoT) technology. They monitor environmental data in real time (such as soil moisture, temperature, light intensity, and rainfall) through devices like soil moisture sensors and weather stations. By combining with the algorithms of the cloud platform, they can automatically adjust the irrigation strategies to achieve precise water supply. For example:

- LoRa Wireless Communication: It supports long-distance and low-power consumption data transmission, which is suitable for the distributed management of large-area green spaces.

- Infrared Image Analysis: Regularly collect infrared images of the irrigated area through drones, analyze the differences in humidity distribution, and dynamically adjust the irrigation range.

Water-saving and Uniform Irrigation Design

- Rotary Sprinkler and Micro-irrigation Tube Technology: The rotary sprinkler can adjust the spraying angle (such as 360° coverage or directional irrigation). The micro-irrigation tube directly delivers water to the roots of plants, reducing evaporation losses, and the water-saving rate can reach 30% - 50%.

- Zoned Rotational Irrigation: Control the independent opening and closing of different zones through solenoid valves to avoid water resource waste. For example, in the design of a riverside green belt, zoned rotational irrigation is adopted, and the solenoid valves in each zone are centrally managed by a controller.

Rainwater Resource Utilization

In response to the problem of urban water shortage, the system often integrates a rainwater collection and purification module. For example, the viaduct green belt connects multi-stage sedimentation tanks through a water divider, collects rainwater and stores it in a reservoir with an overflow hole. It supplies the green belts on and under the viaduct at the same time and regularly updates the water quality to prevent pollution.

Quick Deployment and Easy Maintenance

New equipment such as the Nongtaitou Cloud Head Unit adopts an integrated design. It does not require approval for construction land, can be deployed within 1 - 2 days, supports mobility and repeated use, and is suitable for the flexible adjustment of municipal projects.

II. System Composition and Functional Modules

Perception Layer

- Sensor Network: It includes soil moisture sensors, temperature sensors, light sensors, and weather stations (monitoring wind speed and rainfall).

- Video Monitoring and GIS Location: Achieve remote monitoring of equipment and fault early warning through cameras and geographic information systems.

Control Layer

- Intelligent Control Cabinet/Cloud Platform: Generate irrigation instructions after receiving sensor data and support remote operation via a mobile phone APP.

- Solenoid Valve and Actuator: Control the opening and closing of sprinklers and the adjustment of water pressure according to the instructions.

Irrigation Equipment

- High-pressure Spray System: It has both irrigation and dust suppression functions, is suitable for road green belts, and can adjust the water spraying angle to adapt to different terrains.

- Micro-irrigation Tube Watering Device: Buried in the roots of plants, it slowly releases water through a seepage cover and water-absorbing materials to improve water resource utilization.

III. Typical Application Scenarios and Cases

Urban Road Green Belts

Adopt timed and quantitative spray irrigation, and turn on the dust suppression function during high-temperature periods to improve air quality. For example, in the green belt of a new town road, the designed sprinkler spacing is 17.8 meters, and the row spacing is 23.86 meters to ensure uniform coverage.

Viaduct Green Belts

Carry out zoned irrigation on and under the viaduct, combined with a solar-powered micro-irrigation tube system. For example, in a viaduct project in Xiamen, by using rainwater collection and an open sedimentation tank, the water quality is continuously updated, and the water-saving efficiency is increased by 40%.

Parks and Botanical Gardens

Customize irrigation plans according to plant species. For example, use high-humidity spraying for Phalaenopsis and reduce the water volume for succulent plants. A botanical garden in Beijing achieves precise control through an environmental monitoring system.

Ecological Restoration Projects

In the reclamation of mining areas, the intelligent irrigation system cooperates with soil improvement measures to continuously supply water, promote the restoration of vegetation, and reduce soil erosion.
