At the same time, through the remote monitoring and control function, users can view farmland environmental data and irrigation equipment status in real time through mobile phone APP or computer software, and perform remote operations and adjustments. 2) Intelligent fertilization system: Soil nutrient testing equipment: used to collect soil samples and test their nutrient content, including nitrogen, phosphorus, and potassium; Fertilizer pump: transports chemical fertilizer or liquid fertilizer to the fertilizer application machine; Fertilizer applicator: used to apply fertilizer evenly around the root system of crops; Control system: including controller and related sensors and actuators, used to control the fertilization process and amount of fertilizer; The intelligent fertilization system first obtains soil nutrient data through soil nutrient detection equipment, and then calculates the appropriate amount and time of fertilizer application based on crop growth requirements and soil nutrient conditions; next, the control system controls the fertilizer pump to transport chemical fertilizer or liquid fertilizer to the fertilizer application machine, and the fertilizer is evenly applied around the crop root system through the fertilizer application machine; the system also supports the function of dynamically adjusting the amount and frequency of fertilizer application according to the crop growth stage and nutrient requirements, so as to improve fertilization efficiency and crop yield; 3) Intelligent monitoring system: Various sensors: including temperature and humidity sensors, light intensity sensors, and gas concentration sensors, which are used to collect farmland environmental data in real time; Data acquisition equipment: including data collectors and data acquisition terminals, responsible for transmitting the data collected by sensors to the monitoring center or cloud for processing and analysis; Monitoring center equipment: including servers, displays, and alarm devices, used to receive, process, and analyze data, and to display farmland environmental conditions and abnormal alarm information in real time; The intelligent monitoring system collects environmental data in real time through various sensors installed in the farmland, including temperature, humidity, light intensity, and gas concentration; these data are transmitted to the monitoring center or the cloud through data acquisition equipment for processing and analysis; the monitoring center processes and analyzes the received data, and determines whether the farmland environment is abnormal based on preset thresholds and rules; once an abnormal situation is found, including excessively high temperature or excessively low humidity, the monitoring center will immediately issue an alarm message, and remind the user through an alarm device with sound and light alarms or text message notifications; at the same time, the monitoring center will also display the farmland environmental data in real time on the display for users to view and analyze at any time.
