Abstract

The invention discloses a fertilizer distribution control system and method, which solves the problem that fertilizer distribution equipment is difficult to guarantee uniformity in the prior art, andhas the effect of being capable of improving the fertilizer distribution efficiency, reducing the labor intensity and reducing the waste of fertilizer. The system adopts the technical scheme that thesystem comprises a central control unit, a human-computer interaction module and a visual identification module, wherein the input terminal of the central control unit is connected with a load sensor,a rotate speed sensor and the visual identification module; the output terminal of the central control unit is connected with an electronic throttle valve and an electromagnetic valve; preset fertilizer distribution amount is input to the human-computer interaction module; the load sensor obtains fertilizer change data and inputs the data to the central control unit; the rotate speed sensor collects wheel rotate speed signals and inputs the signals to the central control unit; the central control unit computes practical fertilizer distribution amount and fertilizer distribution vehicle practical traveling speed; the visual identification module recognizes a fertilizer dropping point boundary; the central control unit works out dispersing distance.

Description

technical field [0001] The invention relates to the related technical field of agricultural equipment, in particular to a fertilizer spreading control system and method. Background technique [0002] Existing fertilizer spreaders mainly spread finished fertilizers such as chemical fertilizers, compound fertilizers, and organic fertilizers. The finished fertilizers have stable properties, such as granular and powdery, uniform, and good fluidity. Using conventional fertilizer spreaders, as long as the walking speed is maintained and the speed of the spreader can basically meet the requirements of uniform fertilization. [0003] For composting and retting of livestock and poultry manure organic fertilizers with high moisture content, the physical characteristics of fertilizers are high humidity, caking, and high viscosity. It is difficult to ensure the uniformity of fertilizer spreading, and there is a lack of fertilizer spreading for this kind of fertilizer. equipment, and la...
