Smart watering solution for golf courses
Smart watering solution for golf courses

As the contradiction between global water supply and demand intensifies, precise irrigation of golf lawns must also implement on-time irrigation, on-demand irrigation, and efficient irrigation. This not only enables precise irrigation and water saving, but also helps improve management levels and reduce management costs. The precision, efficiency, comprehensiveness and scientific management of golf course lawn irrigation will contribute to the healthy development of golf courses. In response to the appeal, our company has developed a wireless intelligent watering system for golf courses. It is an all-weather, unattended and unoperated fully automatic watering system specially designed for golf course green belts. The system is mainly composed of wireless sensors, weather stations, smart dome cameras, smart gateways, wireless solenoid valve controllers and other equipment.

Golf irrigation system design differs from other irrigation system designs in many ways. Golf courses generally have a large lawn area (400,000-570,000 square meters), which has its own unique characteristics. The nozzle pressure is high (0.4-0.55MPa), and the irrigation time is only 4-8 hours a day. For example, the size of the stadium, geographical location, climate conditions, etc., so there are still many problems in actual operation.

The areas that require sprinkler irrigation on golf courses include: greens, tee boxes, fairways, and rough areas (including flowers, grass, shrubs), etc. Among them, greens, tee boxes, and fairways need to be irrigated periodically, and greens require more periodic watering among the three. The design of the golf course sprinkler system will directly affect the quality of the golf course lawn and the overall environmental effect of the surrounding environment.

Sprinkler irrigation system design components

Sprinkler irrigation systems can be mainly divided into three categories according to different operating methods: ① Fully automatic system; ② Semi-automatic system; ③ Manual system. The current golf courses in our country are basically dominated by the latter two types. The general sprinkler irrigation system design consists of: ① water source; ② pumping station; ③ water delivery system (pipe network design); ④ control valve; ⑤ sprinkler head. Fully automatic control systems include wired and wireless.

Basis for designing sprinkler irrigation systems

The design basis indicators of the sprinkler irrigation system include: ① The maximum daily water consumption of the lawn under specific circumstances; ② The zoning of the sprinkler system; ③ The number of hours of sprinkler irrigation per day; ④ The frequency of sprinkler irrigation; ⑤ The topography and climate conditions of the sprinkler irrigation area and the prevailing wind direction and intensity throughout the year wait.

Application of Internet of Things Technology

A modern sprinkler system should have soil moisture sensors and weather stations that transmit information to a cloud platform. The cloud platform can automatically adjust the required sprinkler irrigation cycle based on these data, automatically open or close the valve, and implement automated management of the entire process. This greatly saves manpower and saves irrigation water.


Sprinkler irrigation system design

Real-time:Users can monitor air temperature and humidity, wind speed and direction, rainfall, light intensity, ultraviolet radiation, soil moisture content, soil nutrients and other information anytime and anywhere through computers or mobile phones, and based on this information, through advance settings, the cloud platform passes the data The upper and lower limits automatically send instructions to control the action of the water valve for irrigation or manual control.

Real-time: The system uses wireless sensor network technology to monitor golf course lawns in real time, making the arrangement of sensor nodes flexible, convenient and easy to implement. The nodes are all battery powered and can be buried under the turf.

Intelligent: The system can automatically control the amount of watering based on meteorological information, soil moisture content and lawn water needs in different seasons, and perform different amounts of watering according to different plants and terrain to keep the soil moisture at the optimal level required for crop growth. within the range.

Efficient water saving: The system can intelligently irrigate the lawn according to the soil moisture distribution and the topography of the lawn. The system adopts a curve irrigation mode, that is, the amount of irrigation water decreases in a curve as time and soil moisture increase, thereby saving water.

Soil nutrient monitoring: Based on the data returned by the soil nutrient tester, the monitoring and management center can monitor the soil nutrients in the stadium at any time to determine whether fertilization is needed.

Pipe network monitoring: Based on the water pipe pressure sensors arranged on the pipe network, through monitoring, accidental water leakage points can be discovered in time, and the water supply pump can be automatically shut down to reduce property losses.
