Precise crop irrigation algorithm and control system

Abstract

The invention discloses a precise crop irrigation algorithm and a control system. The precise crop irrigation algorithm comprises crop water demand calculation and irrigation schedule calculation; crop water demand calculation adopts a Penman method; a irrigation schedule comprises a watering quota and an irrigation quota; the irrigation schedule is classified according to dry crops and paddy field crops, and different irrigation schedules are executed for different crop types. The irrigation amount is determined according to the irrigation schedules, the irrigation schedules are calculated every ten days by adopting lists and diagrams or computer programming calculation, the control system can collect basic agrometeorology and soil moisture content information, and a new irrigation algorithm is utilized, different irrigation schemes are provided for different farmlands, real-time scheme operation instructions are provided, and meanwhile, the system also has the functions of fertilization management and pest and disease damage management.

Description

technical field [0001] The invention relates to the technical field of intelligent control of crop production, in particular to a precise irrigation algorithm and control system for crops. Background technique [0002] With the further development of the national economy, the use of modern Internet of Things technology to realize the automatic control of water-saving irrigation and fertilization of farmland has become the trend of agricultural information management. The current agricultural operation software generally collects the basic information of agricultural production, and the data processing after collecting the information and the corresponding technical measures require manual background processing, which lacks timeliness and efficiency. For example, the control system used in "Intelligent Control System for Irrigation and Fertilization Based on HORNER OCS" (Xu Huayu, 2020) can intelligently control irrigation and fertilization, but this kind of operating platfor...

Problems solved by technology

The current agricultural operation software generally collects the basic information of agricultural production, and the data processing after collecting the information and the corresponding technical measures require manual background processing, which lacks timeliness and efficiency.

For example, the control system used in "Intelligent Control System for Irrigation and Fertilization Based on HORNER OCS" (Xu Huayu, 2020) can intelligently control irrigation and fertilization, but this kind of operating platform is limited to the indoor Internet of Things operating platform and does not It cannot be artificially controlled remotely and finely, and cannot directly provide a series of specific improvement implementation plans
