摘要
为提高农田信息采集与存储的自动化水平,满足实时准确获取农田环境信息的需要,文章针对早期便携式农田信息采集仪记录与提取实时数据自动化程度低的问题,研制了一套便携式农田信息采集与管理系统。系统分为四个部分:(1)以嵌入式微控制器为核心部件;(2)以闪存控制器为数据存储单元;(3)以USB接口与计算机进行通信;(4)以数据库形式,对采集数据进行分类处理。该系统具有高性能、操作简单、扩展灵活等特点,对农业低成本自动化设备的更新改造具有重要的实用价值。
In order to improve automation level in farmland work,it＇s necessary to collect exact information about field environment in real time.For former portable farmland information collecting instruments,they are incapable of saving the massive data about farmland information automatically.So a new set of portable system for farmland information collection and management is developed to solve this problem.Our system adopts an embedded micro-unit as the core controlling component and flash memory for data storage.Information from multi origins is merged together to acquire accurate farmland information and USB interface technology is applied in our system to communicate with agricultural expert system platform.This system,with simple operating method and smart expanding interfaces,is meaningful in updating agricultural automatic equipments with low cost.
