FM-SKY water-saving irrigation automatic control system

FM-SKY water-saving irrigation automatic control system

one、sketch:

The FM-SKY 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 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:

The FM-SKY irrigation self-control system mainly consists of a central control system (main computer, control cabinet), solenoid valves, soil moisture sensors (capable of measuring soil moisture values), meteorological observation stations (capable of measuring temperature, humidity, wind speed, wind direction, rainfall) and other equipment.

Operators can sit in the control room and comprehensively analyze the collected meteorological data, field soil moisture, and other data. They can use manual or automatic methods to irrigate the entire community without leaving their homes. 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.

The system consists of multiple control units, each managing an area. Using PRS/GSM network, managed uniformly by computers. 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 performed. Obtain weather information through the Internet and implement irrigation in a predictable manner.

IIIThe main functions of the controller and data acquisition are:

Monitor soil moisture content;

Monitoring of EC (conductivity) and pH values (optional);

Monitoring the status of solenoid valves;

Control the status of the solenoid valve;

Communication transmission of various monitoring and control signals;

Alarm for low voltage;
