METHOD AND CONTROL SYSTEM FOR DIFFERENTIAL IRRIGATION OF CROPS Russian patent published in 2021 - IPC A01G25/02 

FIELD: irrigation.

SUBSTANCE: invention relates to a differentiated irrigation technology and solves the problem of remote control and management of water supply, taking into account the irrigation rates for grown agricultural crops when using various types of irrigation systems. For differentiated irrigation control, the field is divided into irrigation areas of arbitrary shape, with different crops grown and different initial soil moisture. Initial data is obtained using a means of dividing the field into sections of arbitrary shape via Wi-Fi or GSM networks, characterizing the irrigation rates and the number of crops planted, the coordinates of the irrigated areas along their borders. Received is initial data from sensors using M2M technology, characterizing the coordinates of planted crops; initial soil moisture, maximum and minimum soil moisture values ​​at a controlled depth. A digital irrigation map is formed, defining at least one irrigation area and at least one irrigation mode of the irrigation area based on the analysis of the initial data obtained. Watering of crops is carried out using at least one irrigation means in accordance with the digital irrigation map, while synchronizing the location of at least one irrigation tool with the digital irrigation map; information is obtained by means of M2M technology on the actual values ​​of soil moisture of at least one irrigated area at different depths, which provides the formation of a database on the irrigated field. At least one irrigation regime is corrected at one irrigation site at least, taking into account the actual values ​​of soil moisture content of at least one irrigation site at different depths. The irrigation map is updated in real time in accordance with the specified at least one irrigation regime; irrigation of crops is carried out using at least one irrigation device in accordance with the updated digital irrigation map, while synchronizing the location of at least one irrigation device with a digital irrigation map, while during irrigation, the nozzle valve is closed if one of the following conditions is met: W_Iu≥W_maxu, W_Im≥W_maxm, W_Il≥W_maxl, , where W_Iu is the current value of the upper level humidity, W_Im is the current value of the average level humidity; W_Il - current value of humidity of the lower level; W_maxu - set values ​​of max humidity of the upper level; W_maxm - set values ​​of max humidity of the middle level, W_maxl - set values ​​of max humidity of the lower level.

EFFECT: increased accuracy of differentiated irrigation of agricultural crops.
