Variable-rate fertilization robot for greenhouse

Abstract

The invention relates to a greenhouse variable-rate fertilizing robot which belongs to the field of automatic control. The greenhouse variable-rate fertilizing robot comprises a self-propelled robot and a fertilizing unit, wherein a single-board computer is arranged in the self-propelled robot, a GPS receiving module and a variable-rate controller are arranged outside the self-propelled robot, and the GPS receiving module is connected with the single-board computer and is used for determining the current position where the fertilizing robot is; and the single-board computer is connected with the variable-rate controller, and the variable-rate controller is connected with the fertilizing unit and is used for controlling the application rate of the fertilizing unit. The invention has the advantages that: firstly, the function of the greenhouse variable-rate fertilizing robot is powerful, the precious variable fertilizing operation can be realized, the utilization ratio of the fertilizer is improved, and the fertilizer efficiency is improved; secondly, the degree of automation is high, and the operating process can be finished after the fertilizing prescription map is input; thirdly, the greenhouse variable-rate fertilizing robot has simple structure and convenient use and can perform operation only by assembling all the parts; and fourthly, the greenhouse variable-rate fertilizing robot has good economic and ecological environment benefits.

Description

(1) Technical field [0001] The invention relates to the field of automatic control, in particular to a greenhouse variable fertilization robot for automatic and precise variable application of powdery or granular solid fertilizers in a greenhouse. (2) Background technology [0002] At present, as one of the main sources of nutrients for crop growth, chemical fertilizers are used in a huge amount. In greenhouse production, in order to pursue high yield, little consideration is given to the fertilizer and fertilizer efficiency level of soil or cultivation substrate and the amount required for crop growth, and excessive application is often caused, which not only leads to waste of fertilizer, but also causes pollution of groundwater resources. Especially in the cultivation and production system with high input and high output in the greenhouse, this contradiction is particularly prominent. [0003] An effective method in line with cultivation and production is to determine the...

Problems solved by technology

In greenhouse production, in order to pursue high yield, little consideration is given to the fertilizer and fertilizer efficiency level of soil or cultivation substrate and the amount required for crop growth, and excessive application is often caused, which not only leads to waste of fertilizer, but also causes pollution of groundwater resources. Especially in the cultivation and production system with high input and high output in the greenhouse, this contradiction is particularly prominent.

[0003] An effective method in line with cultivation and production is to determine the fertilization demand and amount of fertilization for each small piece of land according to the existing fertilizer level in the soil and the nutritional requirements of the cultivated crops, so that the application and utilization rate of fertilizers can reach the best state. However, this method of fertilization At present, there is no automatic and controllable fertilization device, which can only be operated manually, and the work efficiency and quality are low
