The control module is used for acquiring irrigation related information of the target field blocks; wherein the irrigation-related information includes: weather information, soil information, crop information, and water information; acquiring an irrigation control starting request input by a user; wherein the irrigation control start request carries the depth of a water layer of the target field at the current date; determining the growth period information of crops in the target field according to the irrigation related information and the current date; wherein the fertility period information includes: the current growing period of crops in the target field, the starting date and the ending date of each future growing period and water layer depth control parameters, wherein the water layer depth control parameters are water layer depth threshold values and/or soil water content threshold values; generating a control instruction according to the growth period information in the current growth period and each future growth period, and sending the control instruction to an irrigation terminal arranged in the target field;
The irrigation terminal is used for receiving the control instruction sent by the control module and controlling irrigation execution equipment arranged in the target field block to irrigate or drain water to the target field block according to the control instruction;
The irrigation execution equipment is used for irrigating or draining the target field under the control of the irrigation terminal;
The method for determining the growth period information of the crops in the target field according to the irrigation related information and the current date comprises the following steps:
Extracting a start date, an end date and a water layer depth control parameter of each growth period of crops in the target field from the irrigation related information;
Determining a fertility period in which a time interval formed by the start date and the end date contains the current date as a current fertility period, and determining a fertility period in which the start date is after the current date as a future fertility period;
Acquiring the current growth period, the starting date and the ending date of the future growth period and the water layer depth control parameters as growth period information of crops in the target field;
Wherein, the time interval formed by the current date and the ending date of the current fertility period is used for being divided into at least one irrigation period; the irrigation period is a period for irrigation control;
Wherein the crop in the target field is rice;
The method for determining the growth period information of crops in the target field according to the irrigation related information and the current date further comprises the following steps: detecting whether the current date is the beginning date or the ending date of the field-sunning period of the rice in the target field;
Wherein, in the current fertility period and each future fertility period, generating a control instruction according to the fertility period information and sending the control instruction to an irrigation terminal arranged in the target field, the irrigation terminal comprises: if the current date is the starting date of the field-sunning period of the rice in the target field, a preset field-sunning drainage instruction is sent to an irrigation terminal arranged in the target field, so that the irrigation terminal controls irrigation execution equipment arranged in the target field to drain the target field according to the preset field-sunning drainage instruction;
if the current date is the end date of the field-growing period of the rice in the target field, providing a preset field-growing stop prompt message to the user, and when receiving confirmation information corresponding to the preset field-growing stop prompt message, which is input by the user, determining the irrigation quantity corresponding to the end date of the field-growing period according to the water supplementing quantity corresponding to the field-growing period of the rice in the target field, the water layer depth threshold value of the next growing period after the field-growing period, the estimated rising quantity, the estimated leakage quantity, the estimated rainfall and the estimated drainage quantity of the current date, and generating an irrigation control instruction carrying the irrigation quantity, and sending the irrigation control instruction to an irrigation terminal arranged in the target field so that the irrigation terminal controls irrigation execution equipment arranged in the target field according to the irrigation control instruction.
7. An electronic device, the electronic device comprising:
At least one processor; and
A memory communicatively coupled to the at least one processor; wherein,
The memory stores a computer program executable by the at least one processor to enable the at least one processor to perform the irrigation control method of any of claims 1-4.
8. A computer readable storage medium storing computer instructions for causing a processor to execute the irrigation control method of any of claims 1-4.
