1.簡介
隨著時代的發(fā)展，現代農業(yè)與林業(yè)的工業(yè)標準提高，國家對于水果輸入和國外的輸出正在迅速提高。一方面，來自不同地區(qū)的水果在當地銷售，另一方面，大量的水果銷往其他地區(qū)甚至國外，這些水果是根據它們不同的質量而被分類包裝的。為了使這些水果能打包分選分類，我們必須設計出能自動分揀水果的系統(tǒng)，因為如果這些水果僅是靠手工包裝，一方面，這項工作是很困難，同時效率低下，在另一方面，它不符合現代水果打包分選的要求，如今的水果分選分類是多層次，高標準，高衛(wèi)生標準的。
發(fā)達國家在第二次戰(zhàn)爭后，物流中心、配送中心、流通中心成了自動分揀系統(tǒng)的關鍵設備（黃，2002），美國和歐洲在20世紀60年代就使用了自動分揀系統(tǒng)，而日本也在20世紀70年代開始使用該項系統(tǒng)（徐，2002年）。目前，自動分揀系統(tǒng)是被成功應用在郵局。除了上述領域的成功。隨著現代化標準的改進，它也被廣泛用于在越來越多的領域。但現在，幾乎沒有關于水果自動分揀系統(tǒng)的成功使用，因為它涉及到大量的知識和主題，同時，它要求更多更高水平的人工。目前，我們只能看到Fruitonics公司，該公司已設計了一套水果自動分揀系統(tǒng)的消息。
2．水果自動分揀系統(tǒng)的硬件設計
在系統(tǒng)設計的過程中，在對水果進行排序時，應該全面考慮各種因素、各種技術，如檢測和控制技術，計算機外圍設備和接口技術，數字圖像處理技術和模式識別技術的多項技術應用，在同一時間，配合先進的算法與圖案識別技術，提高該系統(tǒng)的水果分揀準確率。
2.1關于水果自動分揀系統(tǒng)的硬件設備
如今有各種各樣的自動分揀系統(tǒng)，其標準是不同的。在一般情況下，自動分揀系統(tǒng)是由七個分區(qū)組成（徐，2002年），它是：收集輸送機，進料輸送機，設置設備的排序指令，匯流設備，分揀輸送機，分揀和卸貨口，電腦控制器（圖1）。
2.2由硬件和水果自動分揀系統(tǒng)的工作原理
水果自動分揀系統(tǒng)是基于傳統(tǒng)的自動分揀系統(tǒng)，但是它又不同的于傳統(tǒng)的自動分揀系統(tǒng)，它是一個是高智能、實時、多層次、多知識領域和多類自動分揀的系統(tǒng)，。此系統(tǒng)具有幾個部分（許，2002），如：輸送器裝置，重量分選裝置，外觀的分揀裝置和質量的分揀裝置等（圖2）。各部分的組合設計構成了水果自動分揀系統(tǒng)。
圖1為水果自動分選系統(tǒng)的硬件結構圖：（1）輸入傳送帶;（2）貨物傳送帶;（3）鋼條輸送帶;（4）分流器;（5）輸出輥;（6）排序端口; （7）信號輸入;（8）激光條形碼閱讀器;（9）探測器; （10）磁信號發(fā)生器;（11）控制器;（12）磁信號接收器;（13）滿量程檢測。
圖2為水果自動分揀系統(tǒng)的硬件系統(tǒng)
水果自動分揀系統(tǒng)的功能模塊是順應其硬件的三個模塊所形成的，他們分別是重量分選模塊，外觀排序模型和質量排序模塊，根據系統(tǒng)所給出的結論，每個功能模塊的工作原理都可以通過下圖進行說明（圖3），（邯，2004年）。
圖3為重量分選設備的硬件結構
2.2.1重量分選設備及其工作原理
需要進行分類排序的水果被傳送帶（圖3）傳送至接收與分發(fā)移動設備上，水果接收與分發(fā)裝置可以檢測由壓力傳感器模擬來的重量信息，水果重量的信息由A / D轉換（朱，2001），數字信息被發(fā)送到計算機，這些信息在計算機中由特殊的軟件計算，計算機所計算的結果由并行接口被發(fā)送到不同的通道（其目的是通過水果接收和分配裝置對可以控制目標的水果控制器進行控制，），并行接口的數字信息從由D/ A轉換器轉換為模擬信號，該模擬信號通過信號放大器被放大，隨后其被發(fā)送水果接收與分配裝置，以控制流向不同重量果實的區(qū)域。為了進入下一個通過其外觀分揀分類階段，水果從重量的分揀裝置輸出被發(fā)送到外觀分揀裝置的分揀裝置區(qū)進行排序。
圖4為重量分選設備的硬件結構
2.2.2外觀分揀設備及其工作原理
從重量分選裝置的水果被發(fā)送到接收和分配設備的外觀分揀裝置（圖4），高速攝像機從不同的角度拍攝水果，相機中的圖像被發(fā)送到計算機的視頻采集卡，計算機通過視頻信息特殊軟件的處理的，根據計算機的結果來確定水果的分類信號，該信號通過并行接口打開不同的排序通道，然后，該信息通過信號放大器被放大。根據控制水果接收與分配裝置，最后水果通過不同的通道被發(fā)送到的封裝設備。
通過攝像機的圖像邊緣檢測與噪聲消除處理（它必須是曲線擬合）（國，2004年），然后將它相匹配，使水果可按其不同的外觀進行排序分類。
2.2.3質量分選裝置其及工作原理
這兩個設備，也就是質量分揀裝置和外觀的分揀裝置，具有相似的工作流程（圖4）。它們有兩點不同：1不同的是，高速攝像機必須為紅外高速攝像頭;另一個不同的是，他們有不同的處理軟件，質量分選裝置的軟件可以根據從相機的圖像處理果實的外觀品質（如顏色和光澤，染色等）和內在質量（其是否為腐爛）。其主要根據從紅外高速攝像頭獲得的圖像和行業(yè)標準來進行排序。在這個排序過程中，它充分利用了數字圖像處理技術與模式識別技術。在一般情況下，第一個步驟是，根據水果的顏色和光澤篩選，第二步驟是根據紅外圖像以水果的內在質量進行篩選。
3水果自動分揀系統(tǒng)的軟件設計
在設計軟件系統(tǒng)的過程中，不同的開發(fā)工具都應該被考慮到，因為它們都關系到系統(tǒng)的硬件。重量排序硬件和計算機的接口都是通過匯編編程語言軟件開發(fā)的，因為它關系到硬件。其他軟件，如數字圖像處理，串行接口通信等，可以通過的VC++開發(fā)，在VC++中它有幾個關于串口通信的特殊控制（東，2005年）。
4總結
水果自動分揀系統(tǒng)是指通過不同的主體聯系到不同的技術形式，如自動化技術，計算機的軟件和硬件技術。數字圖像處理技術，人工智能技術等，本文介紹了水果自動分揀系統(tǒng)的設計思想，包括的硬件，工作原理和軟件設計。最終的應用程序的系統(tǒng)在對農業(yè)生產和管理中可以帶來較大的社會效益和經濟效益。
