Abstract
Description
本創作是一種檢測器及檢測方法,且特別是一種結合人工智慧及光譜檢測之水果甜度檢測裝置及其檢測方法。 This creation is a detector and detection method, and especially a fruit sweetness detection device and detection method that combines artificial intelligence and spectrum detection.
一般果農無力購買高成本的甜度檢測機,所以一般只篩選水果外觀及記錄水果重量,且若有大量水果採收,需要耗費更多時間來篩選,只有當水果送至農會或水果大盤商之後,才有可能量測其甜度,再將水果等級分級,但是這樣做會耗費太多時間,而且其測量方式會破壞水果外觀進而影響賣相。目前台灣農業大多是以人力、或者是破壞性的技術檢測來得知水果的甜度、這樣不僅消耗了大量的人力,且準確性也是不穩定的。 Generally, fruit farmers cannot afford to purchase high-cost sweetness detectors, so they generally only screen the appearance of the fruit and record the fruit weight. If a large number of fruits are harvested, it will take more time to screen, only when the fruit is sent to the farmers’ association or the fruit market After that, it is possible to measure the sweetness of the fruit, and then grade the fruit, but this will take too much time, and the measurement method will destroy the appearance of the fruit and affect the appearance. At present, Taiwan's agriculture mostly uses manpower or destructive technology to detect the sweetness of fruits. This not only consumes a lot of manpower, but the accuracy is also unstable.
依目前農產品的生產追溯系統是依照各農場QR Code的編號去查詢生產者是哪位果農,生產甚麼產品,所以只要在生產追溯系統,打上這個追溯編號,就可以得知消費者買的蔬果是從哪個地方來,但是追溯編號是用QR Code的方式貼在水果紙箱上,這是極有可能被偽造的,而且可能消費者拿到的這盒水果,並不是真正那位農民所生產的。 According to the current production traceability system of agricultural products, the QR Code of each farm is used to query which fruit grower the producer is and what product it produces. So as long as the traceability number is marked in the production traceability system, you can know what the consumers are buying. Where did you come from, but the retro number is QR The Code method is pasted on the fruit carton, which is very likely to be forged, and it is possible that the box of fruit obtained by the consumer is not produced by the real farmer.

由於目前市面上檢測水果甜度的方式大多是使用破壞性分析的檢測方法,而本創作則是利用近紅外線光譜儀且僅利用六個波長之數據進行化合物的分析技術,屬於非破壞性分析的一種方法。原理是利用物質裡分子與原子間因能階的不同所造成反射率,依波長變化而異的特性,辨識檢測物中的特徵物質,再配合已知物質的特性光譜資料庫,推出各點組成及結構。近紅外光譜是研究最多的非侵入式分析技術,近紅外線光區的波長範圍為780~2500nm,大多數物質的分子官能基如C-H,O-H,N-H等,其固定吸收振動光譜都在此範圍,以此作為甜度量測的依據,達成量測水果甜度之目的。 Since most of the methods currently available on the market to detect the sweetness of fruits use destructive analysis methods, this creation is an analysis technique that uses near-infrared spectroscopy and only six wavelengths of data for compound analysis, which is a type of non-destructive analysis. method. The principle is to use the characteristics of reflectivity between molecules and atoms in the substance due to the difference in energy level, which varies according to the wavelength change, to identify the characteristic substance in the test object, and then cooperate with the characteristic spectrum database of the known substance to deduce the composition of each point And structure. Near-infrared spectroscopy is the most studied non-invasive analysis technology. The wavelength range of the near-infrared light region is 780~2500nm. The molecular functional groups of most substances such as CH, OH, NH, etc., have fixed absorption vibration spectra in this range. Use this as the basis for measuring sweetness to achieve the purpose of measuring fruit sweetness.
本創作係一種結合人工智慧及光譜檢測之水果甜度檢測裝置及其檢測方法。請參閱圖1所示,本創作之結合人工智慧及光譜檢測之水果甜度檢測裝置至少包含檢測平台10、近紅外線檢測裝置20、處理裝置30及辨識碼列印機40。其中,檢測平台10具有置物盤11用以放置水果100。近紅外線檢測裝置20係設於檢測平台20上,例如設於置物盤11的旁邊,用以產生至少一紅外光束照射置物盤11上的水果100的表面且接收反射自水果100之表面之至少一反射光束。在本實施例,水果的品種係以芭樂舉例,然而本創作不限於此,本創作適用之品種也可例如為西瓜、鳳梨或哈密瓜等。置物盤11可為靜止式或轉動式。
其中,若為靜止式置物盤11,則近紅外線檢測裝置20可測得水果100的單一表面的反射光束之數據。若為轉動式置物盤11,則水果100可相對於近紅外線檢測裝置20轉動,故近紅外線檢測裝置20可測得水果100的環面的反射光束之數據。
This creation is a fruit sweetness detection device and its detection method combining artificial intelligence and spectral detection. Please refer to FIG. 1, the fruit sweetness detection device combining artificial intelligence and spectral detection of the present invention at least includes a
在本創作的水果甜度檢測裝置中,處理裝置30係設於檢測平台10上,且例如經由電線電性連接紅外線檢測裝置20。處理裝置30係接收近紅外線檢測裝置20所測得的反射光束之數據訊號,藉以進行比對分析。詳言之,處理裝置30係依據反射光束中的一組特定波長之數據比對甜度資料庫,藉以判斷水果之甜度數據,其中此甜度資料庫係對應於此水果之品種。本創作之一特色在於採用非破壞性檢測法,且前述之組波長僅由六個波長組成,其中這六個波長分別為450nm、500nm、550nm、570nm、600及650nm。此外,本創作之另一特色在於利用人工智慧架構依據水果的品種訓練及建立甜度資料庫。舉例來說,本創作可例如先利用人工智慧架構針對特定品種,例如珍珠芭樂,訓練且建立其甜度資料庫。當使用者將珍珠芭樂放置於置物盤11上且以近紅外線檢測裝置20測得此水果的反射光束之後,處理裝置30就可以事先建立之甜度資料庫比對此水果的反射光束中六個波長之數據(如圖2所示),藉以判斷此水果的甜度數據。同理,本創作也可例如先利用人工智慧架構針對多種水果品種分別訓練且建立其甜度資料庫,因此可針對多種水果品種進行檢測及判斷甜度數據。以芭樂為例,水果品種可例如為珍珠芭樂、帝王芭樂、紅心芭樂或土芭樂等。本創作所採用之人工智慧架構係例如為倒傳遞類神經網路架構(BPNN,Back Propagation Neural Network)或隨機森林分類架構(random decision forests)。
In the fruit sweetness detection device of the present invention, the
舉例而言,如圖3所示,處理裝置30係例如以隨機森林分類架構依據複數個樣本水果之組波長及該些樣本水果之甜度值進行訓練以分別獲得對
應於該些樣本水果之種類之甜度資料庫。其中,以芭樂舉例,樣本水果可例如為珍珠芭樂、帝王芭樂、紅心芭樂或土芭樂等。隨機森林分類為機器學習的整合學習的演算法,其流程為隨機生成一個森林,而森林是由多個決策樹組合而成,每棵樹的節點是本創作訓練的特徵資料,當有一個新的輸入樣本進入的時候,就讓森林中的每一棵決策樹分別進行判斷。本創作先利用光譜檢測裝置所取得的六種不同波段的光線波段的資料,再切開水果(樣本水果)使用市售的糖度計量測甜度,建立起資料庫。經過隨機森林法的方式運算,然後預測該水果的光譜為可能屬於哪一類。以本創作所實驗的對象珍珠芭樂而言,其對應的糖度介於10-15之間,檢測的結果就會被分成六類其中的一類。由於本創作中具有通常知識者依據本創作之教示,應可得知如何以隨機森林法依據六個光譜波長的數據進行訓練以建立資料庫,故本創作不另贅述於此。
For example, as shown in FIG. 3, the
此外,如圖4所示,本創作之處理裝置30或可例如以倒傳遞類神經網路架構(Back Propagation Neural Network,BPNN)依據複數個樣本水果之該些組波長及該些樣本水果之甜度值進行訓練以分別獲得對應於該些樣本水果之種類之甜度資料庫。倒傳遞類神經網路架構為一種監督式學習演算法結合反向傳播(Back Propagation)算法,計算神經網路的梯度並且修正權重,以達到更好的模型準確度,以監督式學習的方法訓練光譜資料庫中的資料,訓練出本創作中分析水果甜度的檢測模型,以人工智慧(Artificial Intelligence,AI)的檢測方式減少人力成本以及人為因素造成的錯誤率,提高水果品質。基於相同於前述之理由,由於本創作中具有通常知識者依據本創作之教示,應可得知如何以倒傳遞類神經網路架構依據六個光譜波長的數據進行訓練以建立資料庫,故本創作不另贅述於此。
In addition, as shown in FIG. 4, the
本創作還可例如具有一辨識碼列印機40,俗稱標籤機,其係例如以電線電性連接處理裝置30,且依據處理裝置30之列印指令在貼紙42上列印辨識碼44,以便水果供應者(例如農民)可將此貼紙42貼在水果100上。換言之,當處理裝置30判斷出水果的甜度資料之後,處理裝置30可產生列印指令,用以在貼紙42上列印辨識碼44。辨識碼44係對應於一資訊,以便使用者(例如消費者)可經由掃描的方式辨識出辨識碼44所對應之資訊。其中,辨識碼44例如為二維碼,而使用者可例如以手機等二維碼掃描器(未繪示)掃描且辨識辨識碼44所對應之資訊,藉以至少獲得此水果100的甜度數據。辨識碼列印機40的種類與型號並無特別限定,只要可列印出具有辨識碼44之貼紙42,即可適用於本創作。除此之外,辨識碼列印機40也可為雷射列印機,例如可省略貼紙而直接在水果的表面列印上二維碼。
The present creation may also have, for example, an
在本創作之一實施態樣中,處理裝置30係進一步將水果100之甜度數據及/或水果之生產履歷上傳至位於雲端200的雲端資料庫202,且辨識碼44之資訊係例如為對應於此雲端資料庫202的存取連結。因此,當使用者以手機等二維碼掃描器掃描且辨識出辨識碼44所對應之存取連結時,使用者即可以手機讀取雲端資料庫202,藉以至少獲得此水果100的甜度數據。換言之,某一顆或某一批之水果的辨識碼44只適用於此顆或此批水果。然而,為了避免此辨識碼44被他人盜用且大量複製,因此本創作之另一特色在於上述之存取連結係具有時效性,藉以使得辨識碼44具有一有效期限。舉例來說,上述之存取連結之有效時間可例如為兩周,例如2019年9月1日至2019年9月14日。當使用者在此段時間區間以外的時間掃描辨識碼時,即便獲得存取連結,也會因為存取連結的時效性而無法讀取雲端資料庫。藉此,本創作可增進食品安全性,防止他人偽造(盜
印)標籤貼紙。在另一實施態樣中,雲端資料庫202還可同時記載水果100的甜度數據及食用期限。因此,當使用者(消費者)讀取雲端資料庫202時,不僅可得知水果的甜度數據,還能得知此水果是否已超過食用期限。在又一實施態樣中,辨識碼44的有效期限還可例如為對應於水果100的食用期限。換言之,若水果100的食用期限為一個月,則此辨識碼44的有效期限也可例如訂定為一個月。因此,縱使他人盜印此辨識碼,也會因為辨識碼具有有效期限,而被使用者輕易識破。
