不同的自动售酒机有不同的原理，这些原理大致有以下几种：

Different vending machines have different principles, which are roughly as follows:

静态辨认。这种售酒机里面有很多摄像头，每层都有。经过提早录入商品的外形，颜色，价钱等信息，当用户取走商品后，经过摄像头返回的图像判别顾客拿取的是什么，用户关门后，系统便经过关联账户扣取相应的钱。

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.

这种辨认技术有两个比拟大的缺陷，一是所需摄像头较多，而且每层都需求，层间距还不能太小，不然会影响图像采集，因而空间应用率比拟低，二是图像辨认不太准确，一旦商品互相遮挡，或是两件商品外形太过类似，系统便不能辨认或辨别。

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.

动态辨认。经过摄像头实时采集顾客取货过程，从而判别顾客拿的是什么。这种技术相比于静态辨认来说所需求的摄像头更少，而且并不需求检测一切商品，只需求看顾客取走或者放回的商品即可，摄像头较少而且普通位于门上，因而空间应用率较高。

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.

重力辨认。这种售酒机在每层都有电子秤，提早录入每种商品的重量，然后经过比对顾客购置前后重量的变化，从而判别顾客买的是什么，这种计划弊端明显，先就是无法判别重量十分相近的商品，另外假如商品倾斜或者自动售酒机倾斜，或者商品互相依托，就会影响重力感应，从而影响系统对顾客所取商品的判别。

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计划。即射频辨认技术（RadioFrequencyIdentification）。原理为阅读器与标签之间停止非接触式的数据通讯，到达辨认目的的目的。就是在每个商品上贴一个电子标签，当顾客取走商品后，售酒机就会感应到，从而判别顾客买的是什么。

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.

这种计划比拟成熟，但是弊端明显，先电子标签容易被屏蔽或者损坏，其次电子标签自身需求本钱，因而运营本钱比拟高，另外相比静态或者动态辨认技术，该计划技术含量较低，难以构成技术壁垒。

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.

从以上所讲解的内容来看，靠的还是几种技术，当然如果售酒机出现了故障，我们还是要恪守底线不乱拿东西！关注我们http://www.qfrtrq.com为您带来更多事项了解！

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://www.qfrtrq.com Bring you more information!
