Fertilizer applicator intelligent control system based on Beidou navigation

Abstract

The invention discloses a fertilizer applicator intelligent control system based on Beidou navigation. The fertilizer applicator intelligent control system comprises a navigation assembly and a fertilizer proportioning and conveying assembly; the navigation assembly comprises a main control module, a spectrum recognition module connected with the main control module, a GNSS receiver and an ECU balance controller, wherein the ECU balance controller is connected with a movement control module and a speed control module, and the GNSS receiver is further connected with an antenna; and the fertilizer proportioning and conveying assembly comprises a proportioning control module connected with the main control module, the proportioning control module is connected with a driving module and a distributing module, the driving module is connected with a spiral stirrer, the distributing module is connected with a plurality of discharging gates, the multiple discharging gates are all connected witha stirring box, and the spiral stirrer is arranged in the stirring box. A wireless module is used for controlling operation and sending operation items, the main control module and the proportioningmodule are used for controlling fertilizer to achieve the purposes of precise fertilization and variable fertilization; and the main control module is matched with the GNSS receiver, the ECU balance controller and the movement control module to achieve the purpose of automatic control.

Description

technical field [0001] The invention relates to the technical field of intelligent control, and more specifically relates to an intelligent control system of a fertilizer spreader based on Beidou navigation. Background technique [0002] At present, the management of orchards includes multiple production links such as planting, fertilization, irrigation, pruning, and pest control. Among them, fertilization of fruit trees is a very important and necessary orchard management process. At present, the fertilization methods of fruit trees in my country mainly adopt traditional Due to the uneven fertilization and the difficulty in controlling the amount of fertilization, this method of fertilization not only affects the quality of the fruit, but also causes a serious waste of manpower and material resources, and the corrosiveness of chemical fertilizers will cause serious damage to human health and have a certain impact on the environment. Pollution; in recent years, some working he...

[0002] At present, the management of orchards includes multiple production links such as planting, fertilization, irrigation, pruning, and pest control. Among them, fertilization of fruit trees is a very important and necessary orchard management process. At present, the fertilization methods of fruit trees in my country mainly adopt traditional Due to the uneven fertilization and the difficulty in controlling the amount of fertilization, this method of fertilization not only affects the quality of the fruit, but also causes a serious waste of manpower and material resources, and the corrosiveness of chemical fertilizers will cause serious damage to human health and have a certain impact on the environment. Pollution; in recent years, some working heads can only perform mechanical ditching or digging operations, and need the assistance of fruit farmers to complete fertilization operations. Fixed-point and quantitative control of soil covering and fertilization amount cannot be realized, and labor force has not been completely liberated. Fertilization benefit is low and cost is high

There is also a part of the working head that uses the position information determined by the laser scanner and the sensor to control the fertilization device to perform fixed-point and quantitative fertilization on the fruit trees in the orchard. Although the labor force has been liberated and fixed-point quantitative intelligent fertilization has been realized, the failure rate of the laser scanner and sensors High, and the cost is high, and the reliability and practicability of the use need to be improved
