Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail with reference to the accompanying drawings.

Fig. 1 is a schematic block diagram of a vending machine according to an embodiment of the present invention. Fig. 2 is a schematic perspective view of an automatic vending machine according to an embodiment of the present invention. Fig. 3 is a schematic structural diagram of a goods channel and a linear array CDD of an automatic vending machine according to an embodiment of the present invention.

The following describes the automatic vending machine according to the present embodiment with reference to fig. 1 to 3.

The utility model discloses an automatic vending machine includes automatic vending machine host computer 1, spring goods way 2, linear array CCD component 3 and image recognition module 4. And an image identification mark 5 is arranged at the delivery port of the spring cargo channel 2. The main machine 1 of the vending machine comprises a main board VMC of the vending machine, cash receipt and payment equipment and network communication equipment. The spring goods channel 2 is a rotatable spiral spring, and the spiral spring is controlled by a motor to rotate, so that goods placed at the interval of the spiral spring are pushed towards the goods discharging direction. The linear array CCD element 3 adopts TCD1501C type linear array CCD, the number of photosensitive pixels is 5000, the size of the pixels is 7 Mum multiplied by 7 Mum (the center distance of adjacent pixels), the one-dimensional imaging length of the linear array CCD can reach 35mm, and a two-dimensional image can be obtained by matching with scanning motion.

As shown in fig. 3, the image identifier 5 is disposed at the goods exit of the goods passage and below the goods, when there are goods at the exit, the image identifier 5 will be shielded by the goods, and if the goods are sold out, the image identifier 5 will be exposed and thus captured by the linear array CCD. The linear array CCD element 3 scans and shoots above the outlet of the goods way on the same layer, and the position of the shot image can be recorded while scanning and shooting, so that the linear array CCD element corresponds to the position of the corresponding goods way. In the vending machine of this embodiment, each layer of goods channel is provided with a linear array CCD element 3 to perform reciprocating scanning shooting on the outlet of the layer of goods channel, and specifically, it can be set that the linear array CCD element 3 is used to perform one-time scanning on the goods channel layer completing the goods delivery action after each transaction is completed.

The image identification mark 5 can be set as a color mark which is greatly different from the colors of the goods and the goods channel tray, and can also be a bar code mark. If the color identification is adopted, the image identification module 4 detects the acquired image through an image identification algorithm so as to judge whether the acquired image acquires the color identification, and if the acquired color identification is adopted, the goods in the goods passage are proved to be sold out. If the bar code identification is adopted, the image recognition module 4 carries out binarization processing according to the acquired CCD output waveform so as to obtain corresponding bar code information, then the obtained bar code information is compared with the bar code information which is prestored in the image recognition module 4 and is stuck on the goods channel, and if the bar code information is consistent with the bar code information, the goods on the goods channel are proved to be sold out.

The image identification module 4 transmits the information of whether goods in the goods channel are sold out to the vending machine host 1, and the vending machine host 1 transmits the corresponding goods selling out information to the remote server through the network module. The above, only be the embodiment of the present invention, the protection scope of the present invention is not limited thereto, and any technical personnel familiar with the technology are in the technical specification of the present invention, to the modification or replacement of the present invention, all should be within the protection scope of the present invention.
