Description

Technical Field

[0001] The present invention relates to the technical field of pipes, and more specifically, to a pipe coding method and system. Background Art

[0002] Pipeline coding refers to the coding operation of the produced pipes. The coding is marked on the outside of the packaging in the form of a barcode, which can be read by scanning or by the naked eye. The barcode information can be used by consumers to identify the authenticity and check the quality. At present, manufacturers mainly use the following methods to perform coding operations:

[0003] When the pipe needs to be coded, the network request is made to call the coding system to generate the corresponding barcode, which is stored in the database and then returned to the coding device. This method is highly dependent on the network. When the network is abnormal, it will affect production. In addition, the output of pipes is large, and the barcode data stored every day is relatively large, which has high storage requirements. Summary of the invention

[0004] The purpose of the invention is to solve the technical defects of the methods provided by the prior art, such as high dependence on the network, large amount of barcode data stored every day and high storage requirements, and to provide a pipe coding method.

[0005] In order to achieve the above invention purpose, the technical solution adopted is:

[0006] The pipe coding method comprises the following steps:

[0007] S1. Register the production equipment and download the production work order information according to the production equipment number;

[0008] S2. Set the coding time interval;

[0009] S3. After receiving the coding instruction, call the coding system to obtain the unique key and cache it locally; obtain the real-time timestamp regularly according to the set coding time interval;

[0010] S4. The obtained production work order information, real-time timestamp, and unique key form a digital code, encrypt the digital code to obtain an encrypted barcode, and send the obtained barcode to the inkjet printer for production inkjet printing.

[0011] Preferably, in step S4, encrypting the digital code specifically includes:

[0012] Data reverse shift operation;

[0013] Reverse operation of digit addition;

[0014] Data forward shift operation;

[0015] Data segmentation reverse operation.

[0016] Preferably, the data reverse shift operation specifically includes:

[0017] Reverse the digital code from the highest digit to get its ASCII code, subtract 48 and compare it with the previous digit. If it is less than 0, get the first new code through (ASCII code of current digit of barcode - ASCII code of previous digit of barcode + 10 + 48) + current barcode; if it is greater than 0, get the first new code through (ASCII code of current digit of barcode - ASCII code of previous digit of barcode + 48) + current barcode; then add the first ASCII code of the original digital code to the first new code to get the digital code after the reverse shift operation of the data.

[0018] Preferably, the inverse operation of digital addition specifically includes:

[0019] Loop the digital code in reverse order starting from the highest digit, subtract the ASCII code of the current value of each digit from the ASCII code of the previous digit, if it is less than 0, add 10 to get the second new code; then add the first ASCII code of the original digital code to the second new code to get the digital code after the reverse operation of digit addition.

[0020] Preferably, the data forward shift operation specifically includes:

[0021] Loop the digital code forward from the lowest bit to each bit, and then perform the following operations:

[0022] Key offset bit = ASCII code of the current cycle number of the digital code - 48;

[0023] Key bit value = key gets the corresponding value according to the key offset bit and then converts it into ascii code;

[0024] Digital code A = key bit value + ASCII code of the current cycle number of the digital code – 48;

[0025] When digital code A is greater than 9: digital code B = digital code A-10, otherwise: digital code B = digital code A;

[0026] The latest digital code = ascii (digital code B + (digital code B + 48).

[0027] Preferably, the data segmentation inverse operation specifically includes:

[0028] Reverse the digital code for each bit and then perform the following operations:

[0029] Left segment data = left segment data + ascii (2*(number of cycles + 1) - 2), when the number of cycles is the first time; the left segment data is empty;

[0030] Right segment data = right segment data + ascii (2*(number of loops + 1) - 1), when the number of loops is the first time, the right segment data is empty;

[0031] The left segment data is executed cyclically: if the ascii code of the key array (number of cycles) is less than the left segment data (number of cycles), digital code A1 = digital code A1 + ascii (key array (number of cycles)) + 10; new left segment data = left segment data + digital code A1 - ascii (right segment data (number of cycles)) + 48;

[0032] The right segment data is executed cyclically: if the ascii code of the key array (number of cycles) is less than the left segment data (11-number of cycles), digital code A2 = digital code A2 + ascii (key array (number of cycles)) + 10; new right segment data = right segment data + digital code A2-ascii (left segment data*ascii(11-i)) + 48;

[0033] The latest digital code = new left segment data + new right segment data.

[0034] Preferably, the production work order information includes work orders, materials, and production quantities.

[0035] Preferably, the real-time timestamp is a millisecond level timestamp.

[0036] Preferably, the encrypted barcode is a 16-digit digital code.

[0037] At the same time, the present invention also provides a pipe coding system, the specific scheme is as follows:

[0038] A pipe coding system, comprising a work order information acquisition module, a coding time interval setting module, a secret key acquisition module and a coding module;

[0039] The work order information acquisition module is used to register production equipment and download production work order information according to the production equipment number;

[0040] The coding time interval setting module is used to set the coding time interval;

[0041] The key acquisition module is used to call the coding system to obtain the unique key after receiving the coding instruction and cache it locally; it obtains the real-time timestamp regularly according to the set coding time interval;

[0042] The coding module is used to obtain the production work order information, real-time timestamp, and unique key to form a digital code, encrypt the digital code, obtain the encrypted barcode, and send the obtained barcode to the inkjet printer for production coding.

[0043] Compared with the prior art, the present invention has the following beneficial effects:

[0044] 1) The algorithm flow of the pipe coding method provided by the present invention is mainly performed locally, and there is no need to establish continuous communication with the coding system, thereby reducing dependence on the network.

[0045] 2) The pipe coding method provided by the present invention performs composite encryption through data reverse shift operation, digit addition reverse operation, data forward shift operation, and data segmentation reverse operation, which has high security and is not easy to be cracked.
