Intelligent water-saving irrigation control system

1、 Summary:

MC-SKYThe water-saving irrigation automation system adopts the principle of adapting to local conditions, selects different irrigation facilities according to the different needs of different regions and crops, and uses advanced technologies such as computers, data acquisition controllers, and sensors to monitor and manage farmland irrigation, ensuring timely and appropriate water supply for crop growth, thus achieving the goal of water-saving irrigation and water-saving irrigation automation.

IIEquipment composition and main functions:

MC-SKYThe irrigation self-control system mainly consists of a central control system (main computer, control cabinet), solenoid valvessoil moistureSensors (capable of measuring absolute soil moisture), meteorological observation stations (capable of measuring temperature)linear measure、HumiditywindfastWindRainfall and direction）Composed of equipment.

The operator can sit in the control roomgatherThe meteorological data and field soil that came upmoisture contentAfter comprehensive analysis of the data, irrigate the entire community manually or automatically without leaving home. At the same time, data query systems and printing systems can be used to record, query, and print meteorological data, soil moisture, irrigation settings, irrigation progress, irrigation history records, and other data of the entire irrigation community at any time.

This system consists of multiple control units, each managing an area. utilizePRS/GSMThe network is centrally managed by a central computer. The outdoor air temperature and humidity sensor sends the results to the computer, where irrigation parameters are set and irrigation conditions are statistically analyzed. The data and charts can be stored and displayed on the computer through dedicated software. At the same time, special operations can be manually performedMake it. Obtain weather information through the Internet and implement irrigation in a predictable manner.
