Description

Technical Field

[0001] This application relates to the field of vehicle production management, and in particular to a vehicle QR code media information collection system based on MES system, a method for creating QR code media for vehicle management, electronic equipment, storage media, and a vehicle management QR code media generation system based on MES system. Background Technology

[0002] After a vehicle rolls off the production line, vehicle information needs to be identified at various stages, including self-inspection at the vehicle's China VI emission standard terminal, warehousing and outbound processes, sales and inventory checks, and service and maintenance. Previously, vehicle information collection and configuration queries were done by querying the vehicle's VIN code. However, inputting vehicle information was difficult and carried the risk of data collection errors. Currently, a permanent and easily accessible medium is needed for vehicle information collection.

[0003] With the rapid updates and iterations of QR code technology, QR codes are increasingly being used in the field of information recognition. A QR code is a method of recording specific data information using alternating black and white patterns on a two-dimensional plane, based on certain geometric shapes and rules.

[0004] Currently, the vehicle industry uses specialized permanent marking tape for vehicle nameplates. This material is laser-engraved to create a permanent mark. It is then pasted onto the corresponding location on the vehicle and features waterproof, oil-proof, high-temperature resistance, high adhesion, and cannot be completely removed.

[0005] MES stands for Manufacturing Execution System, a shop floor management system. MES systems have key information collection capabilities, such as binding controller models, engine numbers, and door and hood codes via barcode scanning, thus achieving information binding.

[0006] Therefore, there is a need for a vehicle QR code media information collection system based on the MES system and a method for creating QR code media for vehicle management, so as to optimize the information system for vehicle production. Summary of the Invention

[0007] The purpose of this invention is to provide a synchronous triggering system for lidar and camera, a synchronous triggering method for lidar and camera, an electronic device, a storage medium, and a vehicle platform, thereby solving at least one of a number of technical problems.

[0008] The data embedded in the QR code relies on manual sorting and entry, which is prone to data deviation. Furthermore, the data sources are not consistent and cannot be linked with the production data of the MES system, causing the QR code traceability function to fail.

[0009] The QR code parameters (encoding format, error tolerance, size, material) are not designed in conjunction with the whole vehicle production scenario, which easily leads to problems such as recognition failure, media detachment, and blurring, and cannot be adapted to the high temperature and oily industrial environment such as stamping and painting.

[0010] The lack of a unified standard for QR code production, coupled with inconsistent printing / pasting positions, clarity, and marking rules, makes subsequent data collection difficult, hinders unified management of the entire vehicle process, and results in a high rework rate due to a lack of effective quality verification.

[0011] The QR code production for different scenarios (vehicle body, transfer card, parts) is not differentiated and adapted, the media has insufficient durability, and cannot accompany the entire production cycle of the whole vehicle / parts, affecting the continuity of traceability.

[0012] This invention provides the following solution:

[0013] According to a first aspect of the present invention, a vehicle QR code media information acquisition system based on a MES system is provided, comprising: an information formulation module, a system function expansion module, and an information verification module;

[0014] The information specification module is used to specify the QR code information requirements, arrange the information content, and set the data length of the QR code information.

[0015] The QR code has a fixed data length.

[0016] The QR code data includes fixed position, part number, date, production workshop, and serial number data;

[0017] The system function expansion module is used to add QR code information collection function to the manufacturing execution of the MES system, so as to realize information reading, data interaction and vehicle information binding and adaptation with QR code media;

[0018] The information verification module is used to add fixed position and part number verification functions based on the QR code information expression rules, thereby avoiding information collection errors from the MES system.

[0019] Furthermore, it also includes: an information binding and retrieval module;

[0020] The information binding and retrieval module obtains information by scanning and parsing the QR code with a barcode scanner. After the information verification module determines that the information is correct, it associates the QR code information with the corresponding vehicle information and stores it in the vehicle information database.

[0021] When sales and after-sales related systems scan a QR code, the information binding and retrieval module reads the QR code information and directly retrieves the full information of the vehicle bound to it from the vehicle information database.

[0022] Furthermore, it also includes:

[0023] The information verification module determines whether the QR code information is correct, specifically including:

[0024] Extract the fixed code and part number information after parsing the QR code, and compare it with the preset fixed code and part number data in the MES system;

[0025] If the two pieces of information match, then the QR code information is determined to be correct and meets the conditions for binding the QR code with the vehicle information.

[0026] If the two pieces of information are inconsistent, the QR code information is determined to be incorrect and does not meet the conditions for binding the QR code with vehicle information.

[0027] According to a second aspect of the present invention, a method for creating QR code media for vehicle management is provided, and a vehicle QR code media information collection system based on an MES system is provided, comprising the following steps:

[0028] Step S1: Build a QR code template, and set the laser engraving parameters and engraving area for the laser engraving equipment, including the QR code position, the cutting line position, and the engraving area.

[0029] Step S2: Based on the number of QR codes in the QR code template, create a QR code information text line and uniquely bind it to the corresponding QR code. At the same time, create a serial number text line and a date text line.

[0030] Step S3: Bind the QR code information text line with the corresponding serial number text line and date text line to form QR code data information that integrates fixed information and variable parameters;

[0031] Step S4: Use a laser engraving device to engrave a QR code on the special permanent identification tape. After the engraving is completed, the serial number is automatically refreshed and the QR code data information is automatically refreshed synchronously.

[0032] Furthermore, including:

[0033] Step S1 involves setting up the QR code template, including:

[0034] Each QR code in the array is given an initial value and a unique name. The QR code information is transcoded using the QR code encoding rules. A dividing line is added between adjacent QR codes.

[0035] The red light button displays the laser engraving area of ​​the template. Adjust the position of the red light area to ensure that the engraving area is within the effective working range of the laser engraving equipment.

[0036] Furthermore, including:

[0037] The laser engraving parameters in step S1 include engraving speed and engraving power;

[0038] The laser engraving parameters are iteratively optimized and adjusted based on the actual laser engraving effect.

[0039] Furthermore, in step S4, before laser engraving, the paper output length of the laser engraving tape is set and the paper output is verified to be reasonable.

[0040] After laser engraving is completed, first confirm the physical engraving effect of the QR code and adjust the laser engraving parameters as needed, and then verify whether the QR code data is automatically refreshed according to the preset rules.

[0041] Finally, the effectiveness of the information binding between the QR code and the MES system was tested by scanning with a barcode scanner.

[0042] According to a third aspect of the present invention, an electronic device is provided, comprising: a processor, a communication interface, a memory, and a communication bus, wherein the processor, the communication interface, and the memory communicate with each other via the communication bus;

[0043] The memory stores a computer program, which, when executed by the processor, causes the processor to perform steps such as the QR code media creation method for whole vehicle management.

[0044] According to a fourth aspect of the present invention, a computer-readable storage medium is provided, comprising: storing a computer program executable by an electronic device, wherein when the computer program is run on the electronic device, the electronic device causes the electronic device to perform steps of a method for creating a QR code medium for vehicle management.

[0045] According to a fifth aspect of the present invention, a vehicle management QR code media generation system based on a MES system is provided, comprising:

[0046] Electronic devices, used to implement steps in methods for creating QR code media for vehicle management, etc.

[0047] The processor runs programs, and when the programs are running, they execute steps such as the QR code media creation method for vehicle management based on data output from electronic devices.

[0048] Storage medium used to store programs that, when running, execute steps such as a QR code media creation method for vehicle management based on data output from an electronic device.

[0049] The above solution achieves the following beneficial technical effects:

[0050] This application automatically extracts and organizes core data through the MES system, eliminating errors from manual data entry, and achieving real-time linkage and source consistency between the data embedded in the QR code and the production data of the MES system. This ensures that the QR code traceability function is accurate and effective, meeting the requirements of "one item, one code" digital management.

[0051] This application features a targeted design for QR code parameters and materials. The QR code encoding format supports large-capacity information storage, and an H-level fault tolerance rate ensures normal recognition in complex environments (the recognition rate reaches over 99.6% in environments with LED backlighting and metal reflection). High-temperature and corrosion-resistant materials are suitable for various production stages, ensuring that the QR code does not fall off or become blurred.

[0052] This application uses the MES system to issue unified production standards, standardize the printing / pasting position, clarity and marking rules, and combine them with an automatic verification mechanism after production to build an error prevention system in the production process, greatly reducing the rework rate, ensuring that the QR code production is standardized and uniform, and facilitating subsequent data collection and full-process management.

[0053] This application creates differentiated QR codes for different scenarios such as vehicle body, transfer card, and parts, adapting to the usage needs of each scenario. This ensures that the QR code circulates throughout the entire production cycle of the vehicle / parts, guaranteeing traceability continuity, while improving production efficiency and adapting to the needs of automated production lines.

[0078] If the two pieces of information are inconsistent, the QR code information is determined to be incorrect and does not meet the conditions for binding the QR code with vehicle information.

[0079] Figure 2 This is a flowchart of a method for creating a QR code medium for vehicle management, provided by one or more embodiments of the present invention.

[0080] like Figure 2 The method for creating QR code media for vehicle management, as shown, is based on a vehicle QR code media information collection system of the MES system, and includes the following steps:

[0081] Step S1: Build a QR code template, and set the laser engraving parameters and engraving area for the laser engraving equipment, including the QR code position, the cutting line position, and the engraving area.

[0082] Step S2: Based on the number of QR codes in the QR code template, create a QR code information text line and uniquely bind it to the corresponding QR code. At the same time, create a serial number text line and a date text line.

[0083] Step S3: Bind the QR code information text line with the corresponding serial number text line and date text line to form QR code data information that integrates fixed information and variable parameters;

[0084] Step S4: Use a laser engraving device to engrave a QR code on the special permanent identification tape. After the engraving is completed, the serial number is automatically refreshed and the QR code data information is automatically refreshed synchronously.

[0085] In this embodiment, it includes:

[0086] Step S1 involves setting up the QR code template, including:

[0087] Set the size of a single QR code to 20mm*20mm, leave a 2mm gap between QR codes, and set the QR code template to a 4*5 array based on the specifications of 100mm wide laser tape and 140mm*140mm laser engraving area.

[0088] Each QR code in the array is given an initial value and a unique name. The QR code information is transcoded using the QR code encoding rules. A dividing line is added between adjacent QR codes.

[0089] The red light button displays the laser engraving area of ​​the template. Adjust the position of the red light area to ensure that the engraving area is within the effective working range of the laser engraving equipment.

[0090] In this embodiment, it includes:

[0091] The laser engraving parameters in step S1 include engraving speed and engraving power;

[0092] The laser engraving parameters are iteratively optimized and adjusted based on the actual laser engraving effect.

[0093] In this embodiment, in step S4, before laser engraving, the paper output length of the laser engraving tape is set and the rationality of the paper output is verified. Finally, the paper output length is set to 120mm.

[0094] After laser engraving is completed, first confirm the physical engraving effect of the QR code and adjust the laser engraving parameters as needed, and then verify whether the QR code data is automatically refreshed according to the preset rules.

[0095] Finally, the effectiveness of the information binding between the QR code and the MES system was tested by scanning with a barcode scanner.

[0096] In this embodiment, it includes:

[0097] In step S2, 20 lines of QR code information text are created for the 4*5 array QR code template. The parameter line name of each information text line is matched with the individual name of the corresponding QR code to achieve automatic synchronous update of QR code information.

[0098] The date text line is set to automatic date function, the date format is set to YYYYMM, and the line name is uniformly set to DATE; the serial number text line is named in the order of NO1, NO2...NO20.

[0099] In this embodiment, the parameter binding function is enabled for each serial number in the serial number text line, the serial number is set to 5 digits, and the increment is set to 20;

[0100] The minimum value of NO1 is set to 1001 and the maximum value is set to 99001. The minimum and maximum values ​​of NO2 to NO20 are incremented by 1 sequentially. All serial numbers are set to be cleared monthly.

[0102] An example of the information structure of a single QR code is: 78801088088592[DATE][NO1], and the remaining QR codes are constructed in the same format.

[0103] Specifically, in one embodiment, a vehicle management QR code medium based on the MES system is disclosed. It is made using a QR code medium manufacturing method for vehicle management. The QR code medium uses permanent identification tape special for the vehicle industry as the physical carrier. After laser engraving, it forms a QR code with the characteristics of being waterproof, oil-proof, high temperature resistant, high adhesiveness, and impossible to completely remove.

[0104] The serial number of the QR code has the characteristics of automatic refresh and periodic reset, and the QR code information can be accurately bound to the vehicle QR code media information collection system based on the MES system, enabling rapid reading and retrieval of vehicle information.

[0105] It is worth noting that although this system / device only discloses the above-mentioned modules / units, it does not mean that this system / device is limited to the above-mentioned basic functional modules. On the contrary, what this invention intends to express is that, based on the above-mentioned basic functional modules, those skilled in the art can add one or more functional modules in combination with the prior art to form an infinite number of embodiments or technical solutions. That is to say, this system is open rather than closed. It cannot be assumed that the scope of protection of the claims of this invention is limited to the above-disclosed basic functional modules just because this embodiment only discloses a few basic functional modules.

[0106] In one specific embodiment, a set of vehicle management QR code media based on the MES system is disclosed.

[0107] Firstly, a vehicle QR code media information collection system based on the MES system is designed, including the following steps:

[0108] Step 1: Define the QR code information requirements, arrange the information content, and set the QR code information data length;

[0109] Step 2: Add QR code information collection function to the MES system;

[0110] Step 3: Based on the QR code information rules, add fixed position and part number verification functions to avoid information collection errors.

[0111] Secondly, a QR code medium for vehicle management is designed, including the following steps:

[0112] Step 1: Create a QR code template and set the laser parameters and engraving area;

[0113] Step 2: Based on the number of QR codes in the QR code template, create a QR code information text line and bind it to the corresponding QR code, and create a serial number text line and a date text line.

[0114] Step 3: Bind the QR code information text line to the corresponding serial number text line and date text line to form the QR code data information.

[0115] Step 4: After the QR code is engraved, the serial number is automatically refreshed, and the QR code data information is also automatically refreshed synchronously.

[0116] In this embodiment, Figure 3-8 The following are included: 101: Define QR code information; 102: Add QR code information collection function to MES system; 103: Build QR code template; 104: Create and bind QR code information; 105: Automatic QR code refresh after engraving; 106: QR code binding and verification; 201: Text naming; 202: QR code size; 203: QR code font and encoding rules; 204: QR code array; 205: Dividing line; 206: Red light button (displays the template laser engraving area); 301: Laser engraving parameters for QR code position; 302: Laser engraving parameters for cutting line position; 501: Create QR code information text; 502: Create QR code variable text line; 503: Set automatic date text line; 504: Set automatic QR code serial number; 505: Bind corresponding parameters to QR code information.

[0117] In this embodiment, according to Figure 3 The operational logic of the machine.

[0118] First, the QR code encoding rules need to be confirmed. Based on the required QR code information, the information content is arranged, ultimately setting the QR code to 25 digits, including a fixed digit, the QR code part number, date, production workshop, and serial number. See details below. Figure 4 Based on the content of the QR code, the MES system adds the requirement to collect QR code information and formulates an information verification scheme according to the fixed position of the QR code and the QR code material number.

[0119] The QR code template is created as follows: Initially, the QR code size is defined as 20mm x 20mm (see 202), with a 2mm gap between QR codes. The laser tape width is 100mm, and the laser engraving area is 140mm x 140mm. After evaluation, the QR code template is set as a 4x5 array (see 204). Each QR code is preset with an initial value and named individually (see 201) for easy data binding later. QR codes are converted using QR codes (see 203) and then arranged. After arrangement, dividing lines are added between the QR codes (see 205) to facilitate subsequent removal of the QR codes. After the QR code template is drawn, the red light button is clicked (see 206) to display the template's engraving area in the laser engraving area. The red light area is adjusted to ensure the engraving area is within a suitable range.

[0120] After completing the above QR code template drawing process, laser engraving parameters need to be set for each element of the template. Parameters such as laser engraving speed and power percentage need to be set (see 301 for QR code parameters and 302 for cutting line parameters), and these settings need to be optimized and adjusted based on the subsequent laser engraving effect.

[0121] Create 20 rows of QR code information in the QR code parameter template according to the number of QR codes (see 501). After the parameter row name is set to match the QR code name (201), the QR code information will be automatically updated to the content of that row. Parameters need to be created for the variables in each row of QR code information (see 502). Set the year and month row name to DATE and enable the data "Auto Date - YYYYMM" (see 503); set the serial number names of each row of QR code information to NO1, NO2, NO3... (see 502); and enable the binding parameter for each serial number. For example: NO1 enables automatic serial numbering, sets the number of digits to 5, the increment to 20 (the template has 20 QR codes), the repetition count to 1, the minimum value to 1001, and the maximum value to 99001, and sets the serial number to be reset monthly. This serial number can ensure that the 98,000 vehicles produced by a single workshop each month are not duplicated; NO2 sets the minimum value to 1002, the maximum value to 99002, and so on, which can avoid duplicate QR code serial numbers.

[0122] Based on the encoding rules, begin compiling the encoding structure for each line of QR code information. Enable content binding and create the QR code information content. For example, the first QR code CODE1 is set to: 78801088088592[DATE][NO1]. CODE2, CODE3, and so on. The [] symbol can be used to reference parameters in the corresponding name row.

[0123] After binding and setting all QR code information parameters, set the output length of the laser-engraved tape and test whether the output length is reasonable. The final set length is 120mm.

[0124] Finally, click the start button, and the laser engraving equipment will begin engraving. Confirm the engraving effect and adjust the engraving parameters accordingly. Verify that the QR code data is refreshed according to the rules and scan it with a barcode scanner to confirm its binding with the system.

[0125] In another specific embodiment, a system capable of reading QR code information and binding it to vehicle information is disclosed. Its features include:

[0126] The system uses a barcode scanner to scan and parse the QR code, obtain information, determine whether the QR code information is correct, and store it in the vehicle information.

[0127] When sales, after-sales, and other related systems scan a QR code, they can read the QR code information and retrieve the vehicle information bound to that QR code.

[0128] It also includes the steps of scanning and parsing the QR code with a barcode scanner and obtaining information, and determining whether the QR code information is correct, including: obtaining QR code information, parsing the QR code information and obtaining fixed code and part number information, comparing it with the system preset data, and determining whether the fixed code and part number information is correct;

[0129] If the fixed code and part number information are consistent with the preset data, then the conditions for binding QR code information are met.

[0130] If the fixed code and part number information are inconsistent with the preset data, the conditions for binding QR code information are not met.

[0131] In another specific embodiment, a system capable of automatically generating serial numbers and converting them into QR code media is disclosed, characterized by comprising:

[0132] A set of automatic QR code parameter generation rules: the serial number can be automatically refreshed; there are opening feature codes and part codes as features for identifying QR codes; it can distinguish production workshops and avoid QR code duplication between workshops; it can identify the production year and month; it can automatically refresh the serial number and automatically reset it to zero periodically.
