Agricultural drip irrigation and fertilization intelligent control system

Facilities Agricultural drip irrigation and fertilization intelligent control system

The intelligent control system of facility agriculture dripping fertilization and application is a set of facility automatic monitoring systems developed to achieve modern facility agricultural intelligence and refined control. The intelligent control system for facilities agricultural drip irrigation and fertilization control system is a key component of modern facility agriculture. Adopt intelligent precision control. Water saving, fertilizer, provincial labor, and production increase effects are very significant.

The intelligent control system for fertilization and fertilization of facility agriculture can be widely used in the intelligent control of irrigation fertilizer and fertilization of crops such as greenhouse vegetables, flowers, and fruit trees, and has strong applicability and promotion.

1. System function

1.1 Automatic, manual control function

There is a manual / automatic switch on the control cabinet. Users can use these two methods for irrigation and fertilization control. When the automatic system fails, the manual system can be controlled to increase the flexibility of the system control.

1.2 The constant voltage frequency conversion control function of the water pump

The constant voltage frequency conversion control of the water pump provides a constant pipe network pressure to the system, so that the pressure of the pipe network does not change with the number of open field valves, ensuring the safety and reliable water supply of the system

1.3 Artificial intervention irrigation fertilization function Depending on the irrigation fertilization of multiple valves set by the user, it can achieve automatic irrigation fertilization control of multiple valves at one time.

1.4 Timed quantitative irrigation fertilization function

The amount of irrigation and fertilization of multiple valves set by the user, the initial time, the end time of the irrigation, the period of irrigation, and the irrigation cycle. The system can achieve automatic irrigation fertilization control of multiple valves within one month.

1.5 Condition control irrigation fertilization function

Using soil water potential sensor to monitor the water content of the soil to perform automatic irrigation fertilization control. When the soil water potential reaches the upper limit of the water potential. The computer automatically starts the system for fertilization and irrigation. When the lower limit of the water potential is reached, the irrigation fertilization stops. The computer automatically records the amount of irrigation of the valve, and other valves are carried out in order according to this irrigation. This control method can achieve unmanned irrigation fertilization control of multiple valves.

1.6 Intelligent mixed fertilizer function

According to the pH and concentration EC of the nutrient solution required for crop growth, the computer sets the 1-4 concentrated 100 times mother liquid, 1 kind of 5 % concentration H2SO solution and water automatic mixing according to the pH and EC set value of the fertilizer formula. , Regulate the pH and EC of the nutrient solution to the scope required for the normal growth of the crop to meet the requirements of the crop.

1.7 Statistics, query, and display functions of irrigation fertilizer information

This system can record the daily irrigation and fertilization of each crop's single valve and the number of irrigation fertilizers, and can be continuously stored for 180 days to record information.

1.8 The dynamic display function of the system operation

When the system is running, the main interface of the system shows the currently running program and running valves, and the user has a clear grasp of the system's running status at a glance.

1.9 System security protection function

When the user sets improper settings and the system is abnormal, the computing opportunity will timely send out the alarm to remind the user to intervene. Prevent more harm to systems or crops.
