For example, the smart order operation server 100 generates a random number using a pseudo random number generator, and generates an order identification symbol by calculating the generated random number using a hash function. can The hash function may include at least one of MD1, MD4, MD5, SHS, SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, and HAS-160.

The smart order operation server 100 may transmit an order approval message including location information corresponding to the generated order identification symbol and the selected code reader 400 to the user terminal 200 (S180). In addition, the smart order operation server 100 may transmit an order completion message including the order identification symbol and location information to the store terminal 300 (S190).

The user terminal 200 may generate a two-dimensional orderer code including the order identification symbol (S200). For example, the user terminal 200 may convert the order identification symbol into a binary code and generate a two-dimensional orderer code having a plurality of cells corresponding to the converted binary code. Specifically, the user terminal 200 converts each of the lowercase English letters, uppercase letters, numbers, etc. constituting the order identification symbol into an ASCII code, and converts the converted ASCII code into a binary value, thereby converting the order identification symbol. It can be converted to binary code. For example, ASCII codes and binary values corresponding to lowercase English letters, uppercase letters, numbers, etc. constituting the order identification symbol are shown in Table 1 below.

numbers, English ASCII code Binary value 0 to 9 48-57 11000~111001 a-z 97-122 1100001~1111010 A to Z 65-90 1000001~1011010

Here, binary code conversion may be performed based on Table 1. For example, the store terminal 300 inverts '1' constituting the binary code to '0' and '0' to '1' ( invert) to generate an inverted binary code, and generate a two-dimensional shop code having a plurality of cells corresponding to the inverted binary code.

In addition, the store terminal 300 may periodically generate a message indicating the order progress status, and transmit the generated message to the smart order operation server 100 (S220), and the smart order operation server 100 receives the received The message may be transmitted to the user terminal 200 (S230).

4 is an exemplary diagram for explaining a two-dimensional product code or a two-dimensional orderer code according to an embodiment.

Referring to FIG. 4 , the two-dimensional product code or the two-dimensional orderer code includes a plurality of cells representing one of '1' and '0' arranged according to rows and columns P ( P is a natural number greater than or equal to 2 and corresponds to the number of rows.) x Q (Q is a natural number greater than or equal to 2, which corresponds to the number of columns) may be an image.

In this case, each of the cells may have one of black corresponding to '1' and white corresponding to '0'.

A two-dimensional product code or two-dimensional orderer code is a unique area (UAR) having a unique pattern, a data area (CAR) corresponding to a binary code or inverted binary code converted from an order identification symbol, rows and columns ) may include a parity area PAR disposed at an edge of the .

The unique area UAR is an area in which cells corresponding to '1' and '0' appear alternately in rows and columns, and may be disposed in the center of a two-dimensional product code or a two-dimensional orderer code. In this way, the pattern in which each of the cells corresponding to '1' and '0' appears alternately can correct the distortion of the captured image even if the camera performance is low, It has the advantage of being easy. In addition, even if a two-dimensional orderer code or a two-dimensional product code is recognized using an infrared sensor instead of a camera, the unique area (UAR) is recognized first, and the data area (CAR) is recognized based on the recognized unique area (UAR) This can improve the recognition rate.

The data area (CAR) is an area containing actual data. In the case of a two-dimensional orderer code, it may be an area corresponding to a binary code converted from an order identification symbol, and in the case of a two-dimensional shop code, an order identification symbol is converted It may be an area corresponding to the inverted binary code in which the binary code is inverted. Accordingly, black and white may be inverted between the data area CAR corresponding to the 2D orderer code and the data area CAR corresponding to the 2D shop code. For example, a white cell in the data area (CAR) of the 2D orderer code may be a black cell in the data area (CAR) of the same position in the 2D shop code.

The parity area PAR may be an area containing parity data for correcting an error in the data area CAR. For example, the parity area PAR disposed on the left boundary or the right boundary (shown in the left boundary in FIG. 4) of the two-dimensional product code or the two-dimensional orderer code is included in the row of the data area CAR. It may indicate whether the number of cells corresponding to '1' is odd or even. For example, when the number of cells corresponding to '1' included in the first row of the data region CAR is an odd number, the cell of the parity region PAR disposed at the left boundary in the first row is '1'. and may have a corresponding black color. Also, when the number of cells corresponding to '1' included in the first row of the data region CAR is an even number, the cell of the parity region PAR disposed at the left boundary in the first row corresponds to '0'. You can have a white

Similarly, the parity area PAR disposed on the upper boundary or the lower boundary (shown in the lower boundary in FIG. 4) of the two-dimensional product code or the two-dimensional orderer code is '1' included in the column of the data area CAR. It may indicate whether the number of cells corresponding to ' is odd or even.

In addition, the 2D product code or the 2D orderer code may further include a dummy area DAR corresponding to the remaining areas except for the data area CAR, the parity area PAR, and the unique area UAR. The dummy area DAR is an area containing dummy data, and may be included to form a two-dimensional product code or a two-dimensional orderer code and to improve data recognition accuracy.

That is, the two-dimensional product code or the two-dimensional orderer code according to an embodiment of the present invention can significantly improve recognition accuracy because an error in the data area CAR can be corrected through the parity area PAR.

FIG. 5 is a second sequence diagram illustrating an operation procedure for the smart order system according to FIG. 1 . 6 is an exemplary diagram of a two-dimensional image generated by synthesizing a two-dimensional orderer code and a two-dimensional product code with each other.

Referring to FIG. 5 , a procedure after the orderer code and product code are generated according to FIG. 3 will be described.

Referring to FIG. 5 , the two-dimensional orderer code is recognized by the code reader 400 disposed at a specific place by the user terminal 200 or the two-dimensional product code is attached to the product and then recognized by the code reader 400 . can be (S300).

When the code reader 400 includes a camera, the code reader 400 may transmit the two-dimensional orderer code or two-dimensional product code recognized in the form of an image and its own reader identification symbol to the smart order operation server 100 . (S310).

The smart order operation server 100 may store the two-dimensional orderer code or the two-dimensional product code received by matching the reader identification symbol received from the code reader 400 in the storage device 160 (S320). In addition, the smart order operation server 100 matches the reader identification symbol and stores the 2D product code corresponding to the received 2D orderer code or the 2D orderer code corresponding to the received 2D product code in the storage device 160 . It can be searched in (S330).

In this case, when the two-dimensional orderer code is received and the two-dimensional product code corresponding to the two-dimensional orderer code is searched, it may be determined that the product has arrived at the designated place after the orderer arrives at the designated place. In addition, when a two-dimensional product code is received and a two-dimensional orderer code corresponding to the two-dimensional product code is searched, it may be determined that the orderer has arrived at the designated place after the product has arrived at the designated place. When the received two-dimensional product code or a code corresponding to the two-dimensional orderer code is not searched, it may be determined that the product or the orderer has not yet arrived. Accordingly, subsequent steps S340 and the like are not performed.

The smart order operation server 100 may compare the two-dimensional orderer code and the two-dimensional product code with each other in order to determine whether the orderer and the product are the same order, and generate a receipt completion message based on the comparison result. For example, referring to FIG. 6 , a two-dimensional image synthesized by matching a two-dimensional orderer code and a two-dimensional product code with each other based on a unique area (UAR) is shown.

As in the two-dimensional image shown in Fig. 6, when there is no cell corresponding to white (or '0') in the data area CAR, the two-dimensional orderer code and the two-dimensional product code are generated using the same order identification symbol. can be judged to have been That is, it can be confirmed that the orderer and the product are for the same order. Therefore, when there is no cell corresponding to white (or '0') in the data area (CAR) of the two-dimensional image, the smart order operation server 100 may generate a receipt completion message.

Meanwhile, in another embodiment, the code reader 400 includes an infrared sensor, so that the code reader 400 is a binary code (or inversion) obtained from the data area (CAR) of the two-dimensional orderer code or the two-dimensional product code. Binary code) may be transmitted to the smart order operation server 100 together with the reader identification symbol (S310).

In another embodiment, the smart order operation server 100 may store the received binary code (or inverted binary code) by matching the reader identification symbol (S320). Next, the smart order operation server 100 matches the reader identification symbol and stores the inverted binary code corresponding to the received binary code or the reader identification symbol and the binary code corresponding to the received inverted binary code It can be searched by the device 160 (S330).

When the corresponding binary code or inverted binary code is found, it may be determined that both the orderer and the product have arrived at the designated place. Accordingly, the smart order operation server 100 may compare the binary code and the inverted binary code with each other by XORing the binary code and the inverted binary code with each other (S340). At this time, when a binary code and an inverted binary code are generated according to the same order identification symbol, the XOR operation result is always displayed as '1'. Accordingly, when '0' does not appear as a result of the XOR operation, the smart order operation server 100 may generate a receipt completion message (S350).
