[0075] By setting up a data acquisition device 2 for collecting the soil moisture data sent by each of the detectors 1 and converting at least one of the soil moisture data into analysis data, it is possible to avoid handing over the data collection and analysis work to the control system 4, greatly reducing the computing pressure of the control system 4, achieving timely feedback of the analysis data, and ensuring the beneficial effect of stable and efficient operation of the control system 4.

[0076] By arranging the data transmission device 3 for sending the analysis data to the control system 4, the beneficial effect of automatic data transmission is achieved, and the timeliness of the control system 4 acquiring the analysis data is ensured.

[0077] In an exemplary embodiment, the lawn of a football field is intelligently maintained, and professional sensors assist professional equipment in rapid soil drainage, automatic sprinkler irrigation, low-temperature heating, and vacuum ventilation.

[0078] Sensors are installed under the lawn to monitor the temperature, humidity, exhaust pipe pressure, etc. of the land in real time. The data is updated every 3 minutes and transmitted to the indoor monitoring center in real time for the convenience of staff to handle. The maintenance work is recorded throughout the process and the lawn is managed throughout its life cycle.

[0079] The soil moisture sensor of the present application is a sensor based on the dielectric constant principle; it can quickly, accurately and comprehensively monitor the soil temperature and humidity of different soil layers.

[0080] The temperature and humidity of the soil play a very important role in the growth of crops.

[0087] In this example, soil moisture refers to the degree of dryness or wetness of the soil, that is, the actual water content of the soil, which can be expressed as a percentage of soil moisture to dry soil weight: soil moisture = water weight / dry soil weight × 100%. It can also be expressed as a relative moisture content such as a percentage of soil moisture equivalent to field water holding capacity, or a percentage relative to saturated water content. Based on the relative humidity of the soil, we can know the degree of soil moisture and how much water can be retained, which has reference value for irrigation.
