Different vending machines have different principles, which are roughly as follows:
靜態(tài)辨認(rèn)。這種售酒機(jī)里面有很多攝像頭,每層都有。經(jīng)過提早錄入商品的外形,顏色,價(jià)錢等信息,當(dāng)用戶取走商品后,經(jīng)過攝像頭返回的圖像判別顧客拿取的是什么,用戶關(guān)門后,系統(tǒng)便經(jīng)過關(guān)聯(lián)賬戶扣取相應(yīng)的錢。
Static identification. There are many cameras in this wine vending machine, and they are on each floor. After entering the shape, color, price and other information of the goods in advance, when the user takes the goods, the image returned by the camera determines what the customer takes. After the user closes the door, the system deducts the corresponding money through the associated account.
這種辨認(rèn)技術(shù)有兩個(gè)比擬大的缺陷,一是所需攝像頭較多,而且每層都需求,層間距還不能太小,不然會影響圖像采集,因而空間應(yīng)用率比擬低,二是圖像辨認(rèn)不太準(zhǔn)確,一旦商品互相遮擋,或是兩件商品外形太過類似,系統(tǒng)便不能辨認(rèn)或辨別。
This identification technology has two relatively large defects. First, there are many cameras required, and each layer is required. The layer spacing cannot be too small, otherwise it will affect the image acquisition, so the spatial application rate is relatively low. Second, the image identification is not very accurate. Once the goods block each other, or the two goods are too similar in appearance, the system will not be able to identify or distinguish.
動態(tài)辨認(rèn)。經(jīng)過攝像頭實(shí)時(shí)采集顧客取貨過程,從而判別顧客拿的是什么。這種技術(shù)相比于靜態(tài)辨認(rèn)來說所需求的攝像頭更少,而且并不需求檢測一切商品,只需求看顧客取走或者放回的商品即可,攝像頭較少而且普通位于門上,因而空間應(yīng)用率較高。
Dynamic identification. The camera collects the customer's picking process in real time to determine what the customer is taking. Compared with static identification, this technology requires fewer cameras, and does not need to detect all goods. It only needs to look at the goods that customers have taken or put back. There are fewer cameras and they are usually located on the door, so the space application rate is high.
重力辨認(rèn)。這種售酒機(jī)在每層都有電子秤,提早錄入每種商品的重量,然后經(jīng)過比對顧客購置前后重量的變化,從而判別顧客買的是什么,這種計(jì)劃弊端明顯,先就是無法判別重量十分相近的商品,另外假如商品傾斜或者自動售酒機(jī)傾斜,或者商品互相依托,就會影響重力感應(yīng),從而影響系統(tǒng)對顧客所取商品的判別。
Gravity identification. This wine vending machine has an electronic scale on each floor. The weight of each commodity is entered in advance, and then the weight changes before and after the purchase are compared to determine what the customer bought. This plan has obvious disadvantages. First, it is impossible to identify goods with very similar weights. In addition, if the goods tilt or the automatic wine vending machine tilt, or the goods rely on each other, gravity sensing will be affected, This will affect the system's judgment of the goods taken by customers.
RFID計(jì)劃。即射頻辨認(rèn)技術(shù)(RadioFrequencyIdentification)。原理為閱讀器與標(biāo)簽之間停止非接觸式的數(shù)據(jù)通訊,到達(dá)辨認(rèn)目的的目的。就是在每個(gè)商品上貼一個(gè)電子標(biāo)簽,當(dāng)顧客取走商品后,售酒機(jī)就會感應(yīng)到,從而判別顧客買的是什么。
RFID program. Radio Frequency Identification. The principle is to stop the non-contact data communication between the reader and the tag to achieve the purpose of identification. It is to attach an electronic label on each product. When the customer takes the product, the wine vending machine will sense it, so as to judge what the customer is buying.
這種計(jì)劃比擬成熟,但是弊端明顯,先電子標(biāo)簽容易被屏蔽或者損壞,其次電子標(biāo)簽自身需求本錢,因而運(yùn)營本錢比擬高,另外相比靜態(tài)或者動態(tài)辨認(rèn)技術(shù),該計(jì)劃技術(shù)含量較低,難以構(gòu)成技術(shù)壁壘。
This plan is relatively mature, but its disadvantages are obvious. First, electronic labels are easy to be shielded or damaged, and secondly, electronic labels need their own costs, so the operating costs are relatively high. In addition, compared with static or dynamic identification technologies, the technical content of this plan is low, and it is difficult to constitute a technical barrier.
從以上所講解的內(nèi)容來看,靠的還是幾種技術(shù),當(dāng)然如果售酒機(jī)出現(xiàn)了故障,我們還是要恪守底線不亂拿東西!關(guān)注我們

From what has been explained above, we still rely on several technologies. Of course, if the wine vending machine breaks down, we should stick to the bottom line and not take things randomly! Follow us http://m.2010yyh.cn Bring you more information!
