【摘要】：针对中国当前农业无线监测中农业信息化标准尚未建立,监测终端各不相同,监测系统数据结构兼容性差的问题,该文围绕异构数据规范化设计和管理,开发了面向差异化农业信息监测终端的一体化网络平台。根据异构网络数据特点,将不同监测终端上传的数据格式标准化;基于XML(extensible markup language)和Visual Basic 6.0开发了标准化网管数据接口,将不同终端数据按照通讯协议的标准格式解析、存储数据;基于PHP、My SQL数据库和服务器及网站网页技术设计并搭建了远程监测平台。利用开沟机监测终端进行田间试验,监测耕深和跟踪机具,试验表明:网管数据接口能实时接收并正确解析终端数据;监测平台可实现远程数据的曲线显示、数据导出和控制终端的远程控制、轨迹绘制的功能;通过导出数据的轨迹和平台显示轨迹对比,轨迹精确。该研究解决了监测系统异构数据及终端硬件差异问题,把单机测控应用扩展至广域网,可应用于农机信息的远程实时监测和远程控制,对现代化农业信息化共享有着重要作用。
[Abstract]:In view of the problem that the agricultural information standard has not been established in the current agricultural wireless monitoring in China, the monitoring terminals are different and the data structure compatibility of the monitoring system is poor, this paper focuses on the standardized design and management of heterogeneous data. An integrated network platform for differentiated agricultural information monitoring terminal is developed. According to the characteristics of heterogeneous network data, the data formats uploaded by different monitoring terminals are standardized, and the standardized network management data interface is developed based on XML(extensible markup language) and Visual Basic 6.0. The data of different terminals are analyzed and stored according to the standard format of communication protocol, and the remote monitoring platform is designed and built based on PHP my SQL database and web technology of server and website. The experimental results show that the network management data interface can receive and correctly analyze the terminal data in real time, and the monitoring platform can realize the functions of curve display, remote control of data export and control terminal and trajectory drawing. By comparing the tracks of the data and the display tracks of the platform, the trajectory is accurate. The problem of heterogeneous data and terminal hardware difference of the monitoring system is solved, and the application of single computer measurement and control is extended to the wide area network (WAN). It can be applied to the remote real-time monitoring and remote control of agricultural machinery information, which plays an important role in the sharing of modern agricultural information.
