FIG. 1 is a diagram illustrating a structure of a product damage tracking and managing apparatus for tracking damage to a product in a factory according to an embodiment of the present invention. Referring to FIG.

Referring to FIG. 1, the apparatus for managing damage breakdown tracking 110 according to the present invention includes an information receiving unit 111, an information storing unit 112, and an image transmitting unit 114.

First of all, the present invention is an invention to track whether a breakdown has occurred in a product produced in a factory, in which barcodes for distinguishing each product are attached to products produced in factories, And a plurality of CCTV cameras 11, 12, and 13 for photographing each partial area of the product are disposed in the inspection point 101. The barcode recognizer (not shown) recognizes the barcode attached to the products, , It is assumed that the plurality of CCTV cameras 11, 12, and 13 are connected to the information collecting apparatus 30 located at the inspection point 101.

For example, the CCTV camera 1 (11) is installed to photograph the top of a product, and the CCTV cameras 11, The CCTV camera 2 (12) is installed to photograph the interruption of the product, and the CCTV camera 3 (13) may be installed to photograph the lower end of the product.

Under such circumstances, when the bar code recognizer recognizes the first bar code attached to the first article 20 as the first article 20 is moved to the spot 101 where the inspection operation is performed through the production line of the factory The information collecting device 30 photographs a plurality of partial images of the first product 20 through the plurality of CCTV cameras 11, 12 and 13 connected to the information collecting device 30. [

When the information collecting apparatus 30 photographs a plurality of partial images of the first product 20, the information collecting apparatus 30 transmits the first barcode and the first product 20 to the product breakage tracking management apparatus 110, The first partial image data for the first product 20 and the first time information for the time when the first product 20 is photographed.

At this time, the information receiving unit 111 may receive the first bar code, the plurality of first partial image data, and the first time information from the information collecting apparatus 30.

When the first bar code, the plurality of first partial image data, and the first time information are received from the information collecting device 30, the information storage unit 112 stores a plurality of different bar codes and corresponding bar codes And stores the first bar code, the plurality of first partial image data, and the first time information in the information database 113 in which the partial image data and the time information are stored in association with each other.

In this way, the apparatus breakage tracking management apparatus 110 according to the present invention is capable of detecting the barcode of each product from the information collecting apparatus 30, partial image data, Information can be received and stored in the information database 113.

As a result, data may be stored in the information database 113 as shown in Table 1 below.

barcode Partial image data Visual information Barcode 1 Partial image data 1 Time information 1 Barcode 2 Partial image data 2 Visual Information 2 Barcode 3 Partial image data 3 Visual Information 3 Barcode 4 Partial image data 4 Visual Information 4 Barcode 5 Partial image data 5 Visual Information 5 Barcode 6 Partial image data 6 Visual Information 6 ... ... ...

In this way, it is found that the first product 20 has been damaged in the state where the data is stored in the information database 113. Accordingly, in order to check whether the first product 20 is damaged at the factory, The client terminal 130 transmits the acquired image data to the product damage tracking management apparatus 110 to the first bar code and the first product 20 The transmission request command of the photographed image data can be transmitted.

At this time, when the first barcode is received from the client terminal 130 of the administrator and the command to transmit the photographed image data to the first product 20 is received, the image transmission unit 114 transmits the image data to the information database 113 Extracts the first partial image data and the first time information stored in association with the first bar code, and transmits the extracted first partial image data and the first time information to the client terminal 130.

When the first partial image data and the first time information are received in the client terminal 130, the administrator reproduces the first partial image data and transmits the first partial image data to each portion of the first product 20 It is possible to confirm whether or not the first product 20 has been damaged in the factory.

In this case, according to an embodiment of the present invention, the product breakage tracking management apparatus 110 may further include a playback priority order transmission unit 115. [

The reproduction priority order transmission unit 115 transmits the reproduction priority order number to each of the plurality of first partial image data in the order of importance with a predetermined order based on the priority set for each of the plurality of CCTV cameras 11, It is possible to transmit the information on the reproduction priority order assigned to each of the plurality of first partial image data to the client terminal 130. [

Regarding each of the plurality of CCTV cameras 11, 12, and 13, a predetermined importance may be set in advance. For example, if CCTV camera 1 (11) is a camera that captures a core part of a product, CCTV camera 2 (12) is a camera that captures a major part of a product, and CCTV camera 3 (13) In the case of a camera, importance levels of the CCTV camera 1 11, the CCTV camera 2 12, and the CCTV camera 3 13 may be set in the order of the CCTV cameras 11, 12, and 13.

At this time, the reproduction priority order transmitting unit 115 allocates the highest priority order to the partial image data photographed by the CCTV camera 1 11 among the plurality of first partial image data, The second highest priority sequence number is assigned to the partial image data, and the last priority sequence number is assigned to the partial image data captured by the CCTV camera 3 (13).

Thereafter, the reproduction priority order transmission unit 115 transmits information on the reproduction priority order assigned to each of the plurality of first partial image data to the client terminal 130, The user can be guided to view the video data first.

According to an embodiment of the present invention, the product damage tracking management device 110 performs user authentication on the client terminal 130 when receiving a command to transmit photographed image data from the client terminal 130 And may further include an authentication configuration for transmitting the photographed image data only when the user is a legitimate user.

The client terminal 130 calculates the information entropy based on the preset probability mass function when the acquisition instruction of the photographed image data for the first product 20 is applied by the manager, A correction result value corresponding to an integer of 0 or more can be generated by discarding a decimal point from the calculation result value.

Information entropy is the quantification of the amount of information indicating the degree of uncertainty for events with a certain probability. Regarding the information entropy H [X] for the discrete random variable when the number of x is K, let p (x) be a probability mass function which is a function representing a probability with respect to a specific value in the discrete random variable Can be calculated according to the following equation (1).

In this regard, the client terminal 130 can calculate the information entropy through the calculation according to Equation (1) based on the probability mass function preset for encryption of the bar code, By discarding the decimal point, a correction result value corresponding to an integer of 0 or more can be generated. For example, when the information entropy is calculated as '2.4', the client terminal 130 may generate a correction result value of '2' by discarding the decimal point.

When the correction result value is generated as described above, the client terminal 130 can randomly generate a padding bit string having a predetermined length while having a Hamming Weight corresponding to the size of the correction result value .

 Here, Hamming weight means the number of '1' in the data composed of '0' and '1' codes. In this case, if the correction result is '2' and the predetermined length is '5', then the client terminal 130 determines that the number of '1' is 2 and the length is 5 A bit string for padding of bits can be randomly generated.

Thereafter, the client terminal 130 may encrypt the first bar code by concatenating and padding the bit string for the bit string of the data constituting the first bar code.

For example, when the bit string of the data constituting the first bar code is '11110000' and the padding bit string is generated as '11000', the client terminal 130 concatenates '11000' to '11110000' The encrypted first bar code " 1111000011000 " can be generated.

When the encryption of the first bar code is completed, the client terminal 130 transmits a request to transmit the captured image data to the product damage tracking management device 130 for the encrypted first bar code and the first product 20 Lt; / RTI >

According to an embodiment of the present invention, the image transmission unit 114 may include an extraction unit 116, an identification unit 117, a user authentication completion processing unit 118, and a transmission unit 119.

The extracting unit 116 receives the first barcode encrypted from the client terminal 130 and receives a command to transmit the photographed image data for the first product 20 to be padded to the encrypted first barcode And extracts the padding bit stream having the predetermined length.

The verification unit 117 calculates the verification information entropy based on the same probability mass function as the predetermined probability mass function and then discards the decimal point from the calculation result value for the verification information entropy, Generates a calibration result for verification, and checks whether the hamming weight of the padding bit string matches the hamming weight corresponding to the size of the verification calibration result value.

When the hamming weight of the padding bit string is confirmed to match the hamming weight corresponding to the size of the verification correction result value, the user authentication completion processing unit 118 completes the user authentication to the client terminal 130 .

When the user authentication of the client terminal 130 is completed, the transmitting unit 119 transmits the first partial video data and the first partial video data, which are stored in association with the first bar code, from the information database 113, And transmits the first partial image data and the first time information to the client terminal 130.

1111000011000 'is received in the product damage tracking management device 110, the extracting unit 116 extracts the first bar code from' 1111000011000 'to' 110000011000 ', as in the above- The bit string for padding can be extracted.

The verification unit 117 performs the same operation as in Equation 1 on the basis of the same probability mass function as the probability mass function existing in the client terminal 130 to calculate the information entropy for verification, By discarding the decimal point, a verification correction result value of '2' is generated to check whether the hamming weight of the padding bit string matches the hamming weight corresponding to the size of the verification correction result value.

In the present embodiment, the Hamming weight of the padding bit string is equal to '2', and the sum of '2', which is the hamming weight of the padding bit string, and '2' The coincidence means that the encrypted first bar code is correct based on the information entropy generated on the basis of the same probability mass function pre-shared by the client terminal 130 and the product damage tracking management device 110 The user authentication completion processing section 118 can complete the user authentication of the client terminal 130. [

When the user authentication of the client terminal 130 is completed, since the user of the client terminal 130 is an authenticated user, the transmitting unit 119 stores the first bar code corresponding to the first bar code from the information database 113 The first partial image data and the first time information may be transmitted to the client terminal 130 after extracting the plurality of first partial image data and the first time information.

According to an embodiment of the present invention, the product damage tracking management apparatus 110 may further include an identifier table holding unit 120, a reference identifier extracting unit 121, and a reference image notification message transmitting unit 122.

The identifier table storage unit 120 stores an identifier for each of the plurality of CCTV cameras 11, 12 and 13 and a predetermined reference CCTV camera corresponding to each CCTV camera (the reference CCTV camera includes a plurality of CCTV cameras 11, 12, and 13) are associated with each other and store and store the stored identifier table.

For example, information may be recorded in the identifier table as shown in Table 2 below.

Identifiers of multiple CCTV cameras CCTV camera identifier The identifier of the CCTV camera 1 (11) The identifier of the CCTV camera 2 (12) The identifier of the CCTV camera 2 (12) The identifier of the CCTV camera 3 (13) The identifier of the CCTV camera 3 (13) The identifier of the CCTV camera 1 (11)

That is, in the identifier table, the CCTV cameras 11, 12, and 13 are matched with the reference CCTV cameras, respectively, and the other CCTV cameras predetermined to be highly related to the respective CCTV cameras are matched. The matching between the CCTV cameras is preset by the administrator, and the administrator can match each CCTV camera based on the relationship between the plurality of CCTV cameras 11, 12, and 13. For example, a CCTV camera 1 (11) captures the upper part of the product and a CCTV camera 2 (12) captures an interrupted part of the product. The CCTV camera 1 (11) and the CCTV camera 2 (12) Supposing that the camera is a camera suitable for observing the middle portion of the product, the administrator can match the CCTV camera 2 (12) to the CCTV camera 1 (11) with the reference CCTV camera.

The reference identifier extracting unit 121 extracts the first partial image data and the first time information from the information database 113 and transmits the first partial image data and the first time information to the client terminal 130, A selection of partial image data photographed through the first CCTV camera from the client terminal 130 by applying a reproduction command of the partial image data photographed through the first CCTV camera to the client terminal 130 among the partial image data When the information is received, an identifier for the first reference CCTV camera recorded corresponding to the identifier of the first CCTV camera is extracted from the identifier table.

When the identifier for the first reference CCTV camera is extracted, the reference image notification message transmission unit 122 transmits the partial image data photographed through the first reference CCTV camera to the partial image data captured through the first CCTV camera To the client terminal 130, a reference video announcement message indicating that the reference video is the reference video for the data.

For example, when the administrator has applied the reproduction command of the partial image data photographed through the CCTV camera 1 11 among the plurality of first partial image data to the client terminal 130, the reference identifier extraction unit 121 extracts, Can extract an identifier for the CCTV camera 2 (12) as an identifier for the reference CCTV camera recorded corresponding to the identifier of the CCTV camera 1 (11) from the identifier table as shown in Table 2 above.

Then, the reference video announcement message transmission unit 122 transmits a reference video announcement message indicating that the partial video data shot through the CCTV camera 2 (12) is a reference video for the partial video data shot through the CCTV camera 1 (11) When the manager reproduces the partial image data photographed through the CCTV camera 1 11 through the client terminal 130 and transmits the partial image data captured through the CCTV camera 2 12 to the client terminal 130 It is possible to support the image data to be reproduced and viewed as a reference image.
