摘 要: 跨区域间农业信息化水平的不同,造成传统的跨区域农业病害信息通信系统传输速率慢、通信信号强度弱。为此,设计基于机器视觉的跨区域农业病害信息通信系统,利用以太网实现通信。所设计的系统由970A?G46网卡、网络接口和机器视觉检测模块组成。网络接口将跨区域间的农业病害信息采集系統连接起来后,机器视觉检测模块便开始进行农业病害信息采集系统中跨区域农业病害信息的删减、聚焦和分辨率调节等检测工作,其将检测结果反馈给网络接口,经由网络接口将检测结果传输到970A?G46网卡。970A?G46网卡使用以太网通信流程图实现跨区域农业病害信息的通信。经实验分析可知,基于机器视觉的跨区域农业病害信息通信系统传输速率快、通信信号强度强。

Abstract: The trans?regional agricultural diseases information communication system based on machine vision was designed. The communication is realized with Ethernet. The system is composed of 970A?G46 network card, network interface and machine vision detection module. After the cross?regional agricultural diseases information acquisition systems are linked together through network interfaces, the machine vision detection module begins to make cut, focus and resolution adjustment detection of trans?regional agriculture disease information in the agriculture disease acquisition system and feed the detected results back to the network interface system, which transmits the result to 970A?G46 network card through the network interface. 970A?G46 network card is used to implement cross?regional agricultural disease information communication. The experimental analysis result shows that across regions of agricultural disease information communication system based on machine vision has fast transmission speed and strong communication signal.
Keywords: machine vision; trans?regional agriculture disease; information communication system; 970A?G46 network card

目前,由于受到气候、土壤、地形、污染等因素的限制,我国的农业水平正处于缓慢发展中,农业病害现象时有发生,科研组织不得不采取一定的措施对抗这一现象。跨区域农业病害信息通信系统是一种能够以某一区域农业病害信息为依据,对另一区域进行灾害预警的通信系统,该系统的出现使得我国农业水平得以提升[1?4]。但跨区域间的农业信息化水平不同,造成传统的跨区域农业病害信息通信系统传输速率慢、通信信号强度弱,为此,设计基于机器视觉的跨区域农业病害信息通信系统[5?6]。文献[7]基于多光谱识别对跨区域农业病害信息通信系统进行设计,多光谱识别是一种模拟人类视觉的图像处理技术,其能够有效增强系统的传输速率,但对跨区域间的农业信息化水平的调节能力不强,因此系统的通信信号强度较弱。文献[8]基于温湿度传感器对跨区域农业病害信息通信系统进行设计,这一系统通过监测农业环境的温湿度,对跨区域间可能需求的农业病害信息进行传递,具有传输速率快的优点,但其通信信号强度较弱。文献[9]基于单片机对跨区域农业病害信息通信系统进行设计,该系统使用单片机控制跨区域间的农业病害信息通信,给系统带来了较强的通信信号强度。但由于单片机的处理能力有限,故系统传输速率较慢。文献[10]基于专家诊断对跨区域农业病害信息通信系统进行设计,经专家诊断给出的跨区域农业病害信息具有传输量小、检测时间较长的特点,故系统的通信信号强度较强,传输速率却不快。
