【摘要】：在我国精细农业生产实践中,田间作物监测是关键环节之一。目前我国大多数农田监测系统都是以田间架设监控立杆对作物进行定点监控,这种监控系统前期需要复杂的安装和田间布线,人力和投资成本较高大,监测范围难以覆盖到整个农田,甚至无法获取远程专家系统中农田信息管理与决策分析所需的单株作物的清晰图像。针对当前农田图像获取装置在实时图像采集过程中存在的采集角度小、覆盖范围有限、以及现场采集设备布线繁琐等问题,本文提出并设计了一种基于ARM+Linux平台下的移动式多节点葡萄图像远程获取及控制系统。该系统通过在田间安置带有云台机构的移动式监控设备,组成一个多点覆盖的无线监控网络。设计开发的每个移动式监控设备是一个独立的无线网络工作节点,映射到独立IP地址;在上位机端,通过研发的图形化控制管理界面,选用Telnet终端控制方式、表单按钮控制方式或屏幕重力感应控制方式来实现对每个节点设备的无线远程操控,指挥图像获取设备自动运行到葡萄园指定位置采集图像,采集到的图像信息以实时媒体流的形式在控制界面内显示,,并实现了对历史数据的查看和存储。论文从系统整体方案构建出发,详细分析了系统组成、硬件选择及安装调试,并叙述了其软件平台搭建和编程实现。通过实地测试实验,结果表明,该系统能够满足项目的实时性需求,相较于传统系统提高了控制灵活性以及控制范围等。
[Abstract]:In the practice of fine agriculture in China, field crop monitoring is one of the key links. This kind of monitoring system needs complex installation and field wiring in the early stage, the cost of manpower and investment is high, and the monitoring scope is difficult to cover the whole farmland. It is impossible to obtain the clear image of single crop for farmland information management and decision analysis in remote expert system. In view of the small angle and limited coverage of the current farmland image acquisition device in the process of real-time image acquisition. And the problems such as the complicated wiring of the collection equipment on the spot, This paper presents and designs a mobile multi-node remote image acquisition and control system for grape based on ARM Linux platform. Each mobile monitoring device designed and developed is an independent wireless network working node mapped to an independent IP address. The Telnet terminal control mode, the form button control mode or the screen gravity induction control mode are selected to realize the wireless remote control of each node device, and the command image acquisition device automatically runs to the designated location of the vineyard to collect images. The collected image information is displayed in the control interface in the form of real-time media stream, and the historical data is viewed and stored. The results of field test show that the system can meet the real-time requirements of the project and improve the control flexibility and control range compared with the traditional system.
