Abstract

The invention relates to farmland information collection, in particular to a farmland information collector. The collector satisfies the requirements of fine agricultural farmland information collection and comprises an information processing host and a soil attribute sensor for detecting soil parameters. The information processing host comprises a shell and an information processing circuit arranged in the shell. The information processing circuit comprises a singlechip, a memory connected with the singlechip, a GPS receiving module, an MAX232 level conversion chip, an A / D conversion chip, a humiture sensor for detecting environmental humiture, and a signal amplifying circuit with 3 output terminals connected with the A / D conversion chip. The shell is provided with an LCD display screen connected with the singlechip, a keyboard, a communication interference connected with the MAX232 level conversion chip, and an information collection interface for connecting each sensor with the information processing circuit. The farmland information collector in the invention has a rational and compact structure, is capable of locating farmland measuring points and measuring lots of soil attribute information and environmental information at the measuring points.

Description

technical field [0001] The invention relates to farmland information collection, in particular to a farmland information collection device for mainly acquiring soil attribute information, location information, and farmland environment information. Background technique [0002] Precision agriculture is a modern agriculture based on information and knowledge support. Its core is to dynamically and real-time obtain information on the soil and crops in the farmland area, diagnose the reasons for the temporal and spatial differences in crop growth and yield, and accurately irrigate, fertilize, and spray the area. , to maximize the use efficiency of water, fertilizers and drugs, increase production, reduce environmental pollution, and obtain the best economic and ecological benefits. Among them, quickly and effectively collecting and describing field information that affects crop growth is an important basis for precision agricultural practice. Field information can be roughly di...
