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,由于受到氣候、土壤、地形、污染等因素的限制,我國的農(nóng)業(yè)水平正處于緩慢發(fā)展中,農(nóng)業(yè)病害現(xiàn)象時有發(fā)生,科研組織不得不采取一定的措施對抗這一現(xiàn)象??鐓^(qū)域農(nóng)業(yè)病害信息通信系統(tǒng)是一種能夠以某一區(qū)域農(nóng)業(yè)病害信息為依據(jù),對另一區(qū)域進行災(zāi)害預(yù)警的通信系統(tǒng),該系統(tǒng)的出現(xiàn)使得我國農(nóng)業(yè)水平得以提升[1?4]。但跨區(qū)域間的農(nóng)業(yè)信息化水平不同,造成傳統(tǒng)的跨區(qū)域農(nóng)業(yè)病害信息通信系統(tǒng)傳輸速率慢、通信信號強度弱,為此,設(shè)計基于機器視覺的跨區(qū)域農(nóng)業(yè)病害信息通信系統(tǒng)[5?6]。文獻[7]基于多光譜識別對跨區(qū)域農(nóng)業(yè)病害信息通信系統(tǒng)進行設(shè)計,多光譜識別是一種模擬人類視覺的圖像處理技術(shù),其能夠有效增強系統(tǒng)的傳輸速率,但對跨區(qū)域間的農(nóng)業(yè)信息化水平的調(diào)節(jié)能力不強,因此系統(tǒng)的通信信號強度較弱。文獻[8]基于溫濕度傳感器對跨區(qū)域農(nóng)業(yè)病害信息通信系統(tǒng)進行設(shè)計,這一系統(tǒng)通過監(jiān)測農(nóng)業(yè)環(huán)境的溫濕度,對跨區(qū)域間可能需求的農(nóng)業(yè)病害信息進行傳遞,具有傳輸速率快的優(yōu)點,但其通信信號強度較弱。文獻[9]基于單片機對跨區(qū)域農(nóng)業(yè)病害信息通信系統(tǒng)進行設(shè)計,該系統(tǒng)使用單片機控制跨區(qū)域間的農(nóng)業(yè)病害信息通信,給系統(tǒng)帶來了較強的通信信號強度。但由于單片機的處理能力有限,故系統(tǒng)傳輸速率較慢。文獻[10]基于專家診斷對跨區(qū)域農(nóng)業(yè)病害信息通信系統(tǒng)進行設(shè)計,經(jīng)專家診斷給出的跨區(qū)域農(nóng)業(yè)病害信息具有傳輸量小、檢測時間較長的特點,故系統(tǒng)的通信信號強度較強,傳輸速率卻不快。
