【摘要】 “数字农业”是以生物技术和信息技术为主导的新型农业,在实施“数字农业”过程中,需要一种能在农田中移动的智能试验平台。为此,设计了基于无线局域网的数字农业试验平台无线控制系统。采用组态王软件开发了现场控制系统;利用MFC提供的CSoket类开发通信程序;选用VC++的ADO技术和图形技术,实现网络服务器数据存储与显示;运用ASP技术实现网络服务器端网页程序设计;最后,采用多线程技术和图形仿真技术解决远距离无线通讯产生的数据阻塞和大时延问题。更多还原

【Abstract】 Wireless control system for digital agricultural test platform based on Wireless LAN was designed in this paper. Field control system was developed using Kingview. Communication software was designed using CSoket Class supplied by MFC. Data store and display on the web server was realized by ADO and graph technologies of VC++. The web page design on the web server was realized through ASP technology. Finally, data blockup and large time delay caused by long distance wireless communication were solved by multithreading and graph simulation technologies.更多还原
