I. What the Sector Covers
1.1 Parks, road greens, and the water they use
Smart garden uses IoT, big data, and AI on urban green space, parks, and road planting: irrigation, environment, pests, facility upkeep, and visitor services. Green cover in built-up areas is about 38%, and park green space is about 15 square meters per person. The area to maintain keeps growing, and labor cost is what pushes the work onto sensors.
The National Garden City Standards and the Urban Greening Regulations set maintenance and water-saving irrigation. Sensors, controllers, and cameras water to need, put facilities on one console, and make the maintenance round finer.
1.2 Rules and standards
The Technical Requirements for the Smart City Garden and Greening Information Management Platform set how the platform is built. The gear sits outdoors, so it has to be waterproof, dust-tight, and wide-temperature. 4G and NB-IoT fit irrigation controllers and sensors that are spread across a park.
II. Where a Timer Wastes Water
2.1 Irrigation that ignores the soil
A clock does not know soil moisture or the weather, so it overwaters or underwater. Greening is a real share of municipal water, and the pressure to use less is already there. Irrigation from soil moisture and weather can cut water by 20%–40%.
2.2 A crew that cannot see every valve
Care is watering, pruning, pests, and walking the equipment. Sprinklers, valves, and lights are scattered. A fault waits for the next walk-through.
2.3 Pests and growth judged by eye
Pests need an early find and a precise spray. A walking check covers little of a park. Plant condition and soil are not watched continuously, so the decision stays a habit.
III. Where the Link Is Used
3.1 Irrigation
Soil-moisture sensors and a weather station feed a controller that opens and closes valves on a set policy. Zones, schedules, and a remote manual override are all on it. The same data is what a water-use review uses.
3.2 Lights, fountains, and cameras
Lighting, fountains, and cameras report status and raise a fault on their own. They can be switched remotely and tied to a scene, such as lights on at sunset.
3.3 Pests and how the plants are doing
Pest lamps and spore traps watch insects and disease. Multispectral cameras and sensors watch growth and stress. That is the input for a warning and for spraying only where it is needed.
IV. Numbers and Where It Has Been Used
The numbers: the Ministry of Housing and Urban-Rural Development puts green cover in built-up areas at about 38%, and park green space at about 15 m² per person. Water for garden care is about 10%–20% of municipal water, and smart irrigation can save 20%–40%. One park might hold 10–50 irrigation controllers, 20–100 soil-moisture sensors, and a set of lights and fountains. 4G or NB-IoT fits that spread. A controller uses about 5–10 MB a month.
Where it has been used: a city garden bureau looks after about 500 hectares of park green and installed more than 200 sets of soil-moisture sensors, weather stations, and irrigation controllers on 4G. Irrigation follows ET and soil moisture, and the year saved about 300,000 cubic meters of water. One park put lights, fountains, and cameras on the same platform, with remote switching and scenes, and cut maintenance labor by about 40%.
V. Who Builds It, and Which Rules Apply
The chain runs from irrigation gear and sensors through the IoT platform to garden departments. The Technical Requirements for the Smart City Garden and Greening Information Management Platform set the platform. The Water Quota for Garden and Greening Irrigation sets the water-saving bar. Outdoor gear is specified to IP65 and a wide temperature range.
VI. Terms
- Soil moisture (墒情): water in the soil. It is what an irrigation decision reads.
- ET (evapotranspiration): water lost to evaporation and plant transpiration. It sets how much the plants need.
- Zoned irrigation: greens split by type and area, each zone watered on its own.
VII. Where It Is Heading
AI and vision name pests and score how plants are growing. The city platform takes garden data into urban operations. Lower carbon means rainwater collection and reclaimed water. Visitors get a guide and a count of how crowded a path is.
VIII. Summary
Smart garden ties irrigation controllers, sensors, and facilities so watering, equipment, and the care decision sit on one link. A stable connection is what makes a scattered park install workable.
SimtoLink supplies 4G and NB-IoT SIM cards and communication modules for outdoor, low-power sites, so a garden department can maintain the green from the readings.
