1. INTRODUCTION
With the development of modern agriculture & forestry and the enhance of industrial standard, the output of fruits from inner country and abroad are being raised swiftly. On the one hand, the fruits from different district are sold in local area, on the other hand, more plenty of fruits are sold to other district even abroad, and these fruits demand being packed according to different quality. In order to package these fruits, we must to design a fruit automated sorting system, because if these fruits were packed by hand, one the one hand, The task is hard and it is inefficient; on the other hand, it is not meet the demands of modern fruit package, which is need to be Multi-layer or high standard or high sanitary standard.
To advanced country after second war, the automated sorting system is one of the essential equipment of Logistics centre, Distribution Centre, or circulation centre (Huang, 2002), it was used in American and Europe in the 1960s, automated sorting system was used in Japan in 1970s (Xu, 2002). At the present, automated sorting system is also success used in post office besides above field. With the improvement of modernization standard, it is widely used in more and more field. at the present, almost no success using about fruit automated sorting system because it concern a lots of knowledge and subject, at the same time, it demand more higher level of artificial. At present, we can only see the news about Fruitonics company, which have designed a set of fruit automated sorting system.
2. THE HARDWARE DESIGN OF FRUIT AUTOMATED SORTING SYSTEM
In the course of designing of the System, all kinds of factor are comprehensively thought when fruits are sorted. All kinds of technology,such as detection and control technology, the computer peripheral equipment and interface technology, the digital image processing technology and Pattern Recognition technology, is used, at the same time, advanced algorithm is used in the course of pattern identification, and it improve the accurate rate of fruit sorting.
2.1 The hardware consists of fruit automated sorting system
There are all sorts of automated sorting system, and its standard is different. In general, an automated sorting system is consists of seven partition (Xu, 2002), it is: collection Conveyor, feed Conveyor, the Setting Device Of sorting instruction, confluence device, sorting conveyer, sorting and discharge cargo port, computer controller (Fig. 1).
2.2 The consists of hardware and work principles of fruit automated sorting system
The fruit automated sorting system is based of the traditional automated sorting system, but it is different of the traditional automated sorting system, it is an automated sorting system which is high intelligent, real-time, Multi-layer, multi knowledge fields and multi class. This system has several parts (Xu, 2002), such as: conveyer device, the weight sorting device, the appearance sorting device, and the quality sorting device etc. (Fig. 2).

The work principles of the each function module can be explained by the Figure (Fig. 3) (Han, 2004).
Fig. 3. The hardware consists of the weight sorting device
2.2.1 The weight sorting device and its work principle
The fruit which is need to be sorted is transferred to the fruit receive & distribute device by conveyer belt (Fig. 3), the fruit receive & distribute device can detect the weight information of fruit by pressure sensor , the analog weight information from pressure sensor is transferred to digital information by A/D switch (Zhu, 2001), the digital information is sent to the computer, the computer process these information by special software, the result from computer is sent to different passageway by parallel interface (the purpose is to control the controller from fruit receive & distribute device which can control the destination of the fruits), the digital information from parallel interface is convert to the analog signal by D/A switch, the analog signal is magnified by signal amplifier and it is sent to the fruit receive & distribute device in order to control the Flow Direction of the different weight fruit. In order to enter the next sorting step, which is appearance sorting, the fruit from weight sorting device is sent to the appearance sorting device to be sorted by appearance sorting device.
Fig. 4. The hardware consists of the weight sorting device
2.2.2 The appearance sorting device and its work principle
The fruit from weight sorting device is sent to the fruit receive & distribute device of the appearance sorting device (Fig. 4), the high speed camera shoot fruit from various angles, the image from camera be sent to the computer by the video capture card, the computer process the video information by special software, the result from computer is the classified signal of fruit, the signal open the different sorting passageway by parallel interface, and then the signal is magnified by the signal amplifier. In order to control the fruit receive & distribute device, the fruits are sent to the different passageway, and at last the fruit can be sent to the package device.
The image from camera should be processed by edge detection and noise removing (even it must be curve fitting) (Guo, 2004), and then it be matched to different fruit appearance so that the fruit can be sorted by appearance.
2.2.3 The quality sorting device and its work principle
The two devices, which is the quality sorting device and appearance sorting device, have the similar work process (Fig. 4). there are two different: one different is that the high speed camera must be infrared high speed camera; another different is that they have different process software .the software of the quality sorting device can process the fruit appearance quality (such as color and luster, stain etc) and inner quality (it is rot or not) according to the image from camera. It sorts manly according to the image from the infrared high speed camera and the trade standard. In the process of sorting, it makes full use of the digital image processing technology and
Pattern Recognition technology. In general, the first step is to screen according to color and luster and stain, the second step is to screen the inner quality of the fruit according to the infrared image.
3. THE SOFTWARE DESIGN OF FRUIT AUTOMATED SORTING SYSTEM
In the course of the designing software of the System, different development tool should be thought because it refers to the hardware.

2.2.2外觀分揀設(shè)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(shè)備的外觀分揀裝置(圖4),高速攝像機(jī)從不同的角度拍攝水果,相機(jī)中的圖像被發(fā)送到計(jì)算機(jī)的視頻采集卡,計(jì)算機(jī)通過視頻信息特殊軟件的處理的,根據(jù)計(jì)算機(jī)的結(jié)果來確定水果的分類信號(hào),該信號(hào)通過并行接口打開不同的排序通道,然后,該信息通過信號(hào)放大器被放大。根據(jù)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(shè)備。
通過攝像機(jī)的圖像邊緣檢測(cè)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(jìn)行排序分類。
2.2.3質(zhì)量分選裝置其及工作原理
這兩個(gè)設(shè)備,也就是質(zhì)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(diǎn)不同:1不同的是,高速攝像機(jī)必須為紅外高速攝像頭;另一個(gè)不同的是,他們有不同的處理軟件,質(zhì)量分選裝置的軟件可以根據(jù)從相機(jī)的圖像處理果實(shí)的外觀品質(zhì)(如顏色和光澤,染色等)和內(nèi)在質(zhì)量(其是否為腐爛)。其主要根據(jù)從紅外高速攝像頭獲得的圖像和行業(yè)標(biāo)準(zhǔn)來進(jìn)行排序。在這個(gè)排序過程中,它充分利用了數(shù)字圖像處理技術(shù)與模式識(shí)別技術(shù)。在一般情況下,第一個(gè)步驟是,根據(jù)水果的顏色和光澤篩選,第二步驟是根據(jù)紅外圖像以水果的內(nèi)在質(zhì)量進(jìn)行篩選。
