Automatic wheat seeding system based on location information

Abstract:China's agriculture is changing to the direction of refinement, intelligence and intensification, and precision agriculture technology is introduced into agricultural practice, so as to promote the transformation of modern agricultural development mode and structural adjustment.Among them, "agricultural precision operation and informatization" as the key areas of agricultural modernization development, satellite navigation system and Gaofen satellite remote sensing system as spatial information infrastructure, is an important technical support for precision agriculture, and is the key technology for developing modern agriculture and realizing sustainable agricultural development.

This design is based on the research of Beidou navigation satellite system, combined with embedded software and hardware development, automatic driving control technology and other intelligent technologies.The main design includes the following parts.With Raspberry PI as the core, Beidou satellite navigation is used to plan the working route of agricultural machinery on the map and receive the position information of agricultural machinery.The movement of agricultural machinery is controlled by microcomputer.The seeding device is monitored by photoelectric sensor.
