基于北斗定位的农田变量处方施药喷雾系统
Variable prescription pesticide spraying system for farmland based on the Beidou Navigation Satellite System
摘要
Abstract
A set of embedded farmland information processing system is developed for on -board vari-able pesticide prescription spraying units based on the Beidou Navigation Satellite System to realize on-line variable prescription spraying in farmland and improve pesticide utilization efficiency as well as re-duce the environment and human health hazards caused from pesticide.The EPCS -8980 ARMindus-trial control computer and embedded GIS system are used as information processing unit,the Beidou navigation receivers are adopted as positioning tool and Hall proximity switche sensors are utilized to detect vehicle speed.The on -board computer receives positioning information from the Beidou naviga-tion receivers through RS -232 interface,and communicates with other devices via CAN bus.The em-bedded GIS system is developed with eSupermap,and runs on Windows CE 5.0 operating system.The information processing system is able to generate farmland information distribution map,decide variable pesticide spraying prescription diagram and provide interpretations as well as detect vehicle speed.The test results show that the time for prescription map interpretation is less than 1 s,the grid discriminant error is less than 0.75 m,and the speed detecting error is about ±0.1 km/h.This su-ggests the system can complete its preset functions and realize online variable prescription spraying well.关键词
