Description

Technical Field

[0001] This disclosure relates to the field of vehicle management, and more specifically to management methods, management equipment, and computer program products based on vehicle electronic tags. Background Technology

[0002] In the vehicle production process, to facilitate the identification and production of vehicles on the production line, an electronic tag that can be attached to the vehicle body can be used. The electronic tag records information related to the vehicle it is attached to, such as the vehicle identification number (VIN), vehicle model, and production number. When the production line detects the electronic tag, it can read the vehicle-related information recorded in the tag, determine the next component to be assembled, and activate the corresponding assembly equipment on the production line (such as an industrial robot). Summary of the Invention

[0003] A brief overview of this disclosure is given below to provide a basic understanding of some aspects of it. However, it should be understood that this overview is not an exhaustive summary of this disclosure. It is not intended to identify key or essential parts of this disclosure, nor is it intended to limit the scope of this disclosure. Its purpose is merely to present certain concepts of this disclosure in a simplified form as a prelude to the more detailed description that follows.

[0004] The inventors of this disclosure have noted that electronic tags can be lost or damaged during use. For example, if an electronic tag is lost or damaged during the testing phase after vehicle assembly, it cannot be recycled or reused. Furthermore, because electronic tags are very small and vehicle testing typically takes place outdoors in open areas, it is difficult to detect lost tags in a timely manner, thus increasing the time and difficulty of locating them. Therefore, the loss or damage of electronic tags can disrupt vehicle production and cause significant time and cost losses.

[0005] This disclosure is made in view of the above circumstances, and its purpose is to provide a vehicle-based electronic tag management method, management device, and computer program product that can automatically determine whether a vehicle's electronic tag is lost or damaged, so as to enable timely detection of lost or damaged electronic tags, thereby helping to improve the management details of vehicle production and save time and costs.

[0006] According to one aspect of this disclosure, a method for managing vehicle-based electronic tags is provided. The method includes: acquiring information related to a production order for the vehicle, the information including status information indicating the real-time production status of the vehicle and association information indicating whether the production order for the vehicle is associated with the electronic tag; and determining, based on the status information and the association information, whether the electronic tag is lost or damaged, wherein when the real-time production status of the vehicle is the start of production, the electronic tag is associated with the production order for the vehicle, information related to the vehicle is written to the electronic tag, and the electronic tag is attached to the vehicle; when the real-time production status of the vehicle is the end of production, the electronic tag is removed from the vehicle, the information related to the vehicle in the electronic tag is cleared, and in response to the clearing of the electronic tag, the production order is deassociated with the electronic tag.

[0007] According to another aspect of this disclosure, a vehicle-based electronic tag management device is provided, the management device comprising: a memory storing program instructions; and one or more processors configured to execute the program instructions, thereby causing the device to perform a management method based on the electronic tag, the management method comprising: acquiring information related to a production order of the vehicle, the information including status information indicating the real-time production status of the vehicle and association information indicating whether the production order of the vehicle is associated with the electronic tag; and determining, based on the status information and the association information, whether the electronic tag is lost or damaged, wherein, when the real-time production status of the vehicle is the start of production of the vehicle, the electronic tag is associated with the production order of the vehicle, information related to the vehicle is written to the electronic tag, and the electronic tag is attached to the vehicle; when the real-time production status of the vehicle is the end of production of the vehicle, the electronic tag is removed from the vehicle, the information related to the vehicle in the electronic tag is cleared, and in response to the clearing of the electronic tag, the production order is deassociated with the electronic tag.

[0008] According to another aspect of this disclosure, a computer program product is provided, the computer program product comprising a computer program that, when executed by a processor, causes the processor to perform the management method of this disclosure. Attached Figure Description

[0023] [Electronic Tags and Examples of Their Applications]

[0024] To facilitate a better understanding of this disclosure, please refer first to... Figure 1 This document describes electronic tags for vehicles according to embodiments of the present disclosure and examples of their applications.

[0025] Figure 1 This is a schematic diagram of an application scenario 10 of the electronic tag 1200 of a vehicle 1100 according to an embodiment of the present disclosure. In application scenario 10, the vehicle 1100, electronic tag 1200, assembly area 1300, testing area 1400, and electronic tag reset area 1500 are shown. The assembly area 1300 includes a production line 1310, an assembly start point P0, and an assembly end point P1. The testing area 1400 includes a test route 1410. The electronic tag reset area 1500 includes an electronic tag reset point P2. Figure 1 The solid black line with arrows in the diagram indicates the approximate movement path of the electronic tag. Note that the following references... Figure 1 Unless otherwise specified, the description refers to the case where the electronic tag 1200 is undamaged or lost.

[0026] Vehicle 1100 can be any vehicle before it leaves the factory. The electronic tag 1200 can be attached to the vehicle body of vehicle 1100, for example, by adhesive or other means. For example, to facilitate detection of the electronic tag 1200 by inspection equipment (not shown) in production line 1310, the electronic tag 1200 can be attached to the outer surface of vehicle 1100, such as to the hood of vehicle 1100. Although Figure 1 The image shows a vehicle 1100 with the electronic tag 1200 attached, but as described later, the vehicle 1100 and the electronic tag 1200 can also be separated before and after the start of production of the vehicle 1100. Furthermore, although... Figure 1 The diagram shows the outline of the body of a fully assembled vehicle 1100, but vehicle 1100 can also be a component or combination of components of an incompletely assembled vehicle. In this document, a vehicle (e.g., vehicle 1100) can be either an incompletely assembled vehicle or a fully assembled vehicle. In the case of an incompletely assembled vehicle, assembled components or combinations of components are represented.

[0027] The electronic tag 1200 may be, for example, a small electronic device including a storage module and a communication module, capable of being attached to the vehicle body of the vehicle 1100 by means of adhesive or other methods as described above. The storage module of the electronic tag 1200 can be used to store information related to the vehicle 1100, such as the vehicle identification number, model, and production number of the vehicle 1100. The communication module of the electronic tag 1200 may include, for example, a low-frequency communication circuit capable of transmitting low-frequency wireless signals to enable detection equipment to detect the electronic tag 1200. Furthermore, the communication module of the electronic tag 1200 can also send information stored in the storage module to the detection equipment and store information received from the detection equipment into the storage module, thereby enabling the reading and writing of the electronic tag 1200. In this document, the specific configuration of the electronic tag 1200 is not limited. The electronic tag 1200 only needs to be able to store information related to the vehicle 1100 and be detectable by the detection equipment.

[0028] Assembly area 1300 is the area used for the assembly stage of vehicle 1100, including production line 1310. Production line 1310 is used to assemble vehicle 1100 and may include, for example, assembly equipment (e.g., industrial robots, robotic arms, etc.), detection equipment (e.g., position sensors), conveyor belts, etc., not shown. Furthermore, assembly area 1300 also includes an assembly start point P0 (hereinafter sometimes simply referred to as point P0) and an assembly end point P1 (hereinafter sometimes simply referred to as point P1). Point P0 is the location where the assembly of vehicle 1100 begins, and as described later, it is also the location where the production of vehicle 1100 begins. Point P1 is the location where the assembly of vehicle 1100 ends. For example, detection devices capable of detecting electronic tags 1200 and recording the time of detection of electronic tags 1200 can be installed at points P0 and P1. Preferably, the detection device at point P0 has communication capabilities, enabling reading and writing operations on production orders and / or electronic tags 1200 for vehicle 1100. The reading and writing operations of the production order of vehicle 1100 can be performed by the detection device receiving information from the device managing the production orders of vehicle 1100 (hereinafter sometimes referred to as the "order management device") and sending information to the order management device, and the order management device reading and writing the production order of vehicle 1100, or by the detection device directly reading and writing the production order of vehicle 1100. The reading operation of electronic tag 1200 can be performed by the detection device directly reading and writing the electronic tag 1200. In the following, the reading and writing operations of the detection device at point P0 on the production order of vehicle 1100 and / or electronic tag 1200 are described as the detection device directly reading and writing the production order of vehicle 1100 and / or electronic tag 1200, omitting any possible intermediate processes.

[0029] Test area 1400 is the area used for the testing phase of vehicle 1100, including test route 1410. Test route 1410 is used to drive the assembled vehicle 1100 along test route 1410 to test various functions of vehicle 1100. Although Figure 1 The diagram shows a zigzag test route 1410, but the test route 1410 may not have a fixed position or shape. In this document, the test route 1410 refers to the trajectory of the vehicle 1100 during testing, that is, the trajectory of the electronic tag 1200 attached to the vehicle 1100 within the test area 1400. Since the test area 1400 is typically an open outdoor area, and depending on the environmental conditions and test items, the electronic tag 1200 may detach from the vehicle 1100 and be lost within the test area 1400.

[0030] The electronic tag reset area 1500 is an area for recycling and resetting the electronic tag 1200, including the electronic tag reset point P2 (hereinafter sometimes simply referred to as point P2). Point P2 is the location where the electronic tag 1200 is reset; for example, a detection device capable of detecting the vehicle 1100 and recording the time of detection, and a reset device capable of clearing the contents stored in the electronic tag 1200 can be installed. Preferably, the detection device and the reset device at point P2 have communication capabilities, enabling read and write operations on the production order of the vehicle 1100. Similar to point P0, the read and write operations on the production order of the vehicle 1100 can be performed directly by the detection device and the reset device, or via an order management device. In the following, the read and write operations on the production order of the vehicle 1100 by the detection device and the reset device at point P2 are described as the detection device and the reset device directly reading and writing the production order of the vehicle 1100, omitting any possible intermediate processes.

[0031] In this document, the production of vehicle 1100 is generally divided into an assembly stage and a testing stage after assembly. The vehicle manufacturer begins production of vehicle 1100 based on the received production order, that is, the assembly stage and the testing stage are carried out sequentially. The production order for vehicle 1100 can be data in any format that includes information related to vehicle 1100 as described above, such as spreadsheets, database entries, etc. Furthermore, as described later, in some embodiments, the production order for vehicle 1100 may also include status information indicating the real-time production status of vehicle 1100 and association information indicating whether the production order for vehicle 1100 is associated with electronic tag 1200.

[0032] In this paper, the start of assembly of vehicle 1100 is defined as the start of production of vehicle 1100, the end of testing of vehicle 1100 is defined as the end of production of vehicle 1100, and the state of vehicle 1100 between the start of assembly and the end of production is defined as being in production. Therefore, in this paper, the real-time production status of vehicle 1100 includes the start of production (assembly start), being in production (assembly in progress, assembly completed, or testing in progress), and the end of production (testing completed).

[0033] In some embodiments, when the real-time production status of vehicle 1100 is the start of production of vehicle 1100, electronic tag 1200 is associated with the production order of vehicle 1100, information related to vehicle 1100 is written to electronic tag 1200, and electronic tag 1200 is attached to vehicle 1100. In some embodiments, when the real-time production status of vehicle 1100 is the end of production of vehicle 1100, electronic tag 1200 is removed from vehicle 1100, the information related to vehicle 1100 in electronic tag 1200 is cleared, and in response to the clearing of electronic tag 1200, the production order is deassociated with electronic tag 1200. (Refer to the following...) Figure 1 The process is described in detail in conjunction with the production of vehicle 1100 and the movement of electronic tag 1200.

[0034] After the vehicle manufacturer receives the production order for vehicle 1100, it prepares the initial assembly components of vehicle 1100 (such as the hood) and electronic tags 1200 that have not yet been written with any vehicle-related information. Then, vehicle 1100 and electronic tags 1200 arrive at point P0 in assembly area 1300 in a separate state.

[0035] At point P0, production of vehicle 1100 begins. At this time, the real-time production status of vehicle 1100 is the start of production. For example, the detection device at point P0 can record the time when electronic tag 1200 arrives at point P0 and is detected as the production start time (i.e., assembly start time) F0 Time of vehicle 1100. At this time, for example, the detection device can read the production order of vehicle 1100 from a database storing production orders (hereinafter sometimes referred to as the "order database"), and change the information indicating the production status in the production order of vehicle 1100 to information indicating the start of production of vehicle 1100 (e.g., writing "production start" in text form, or changing the code indicating the production status to the code indicating the start of production). Alternatively, the detection device can write the recorded production start time F0 Time into the production order of vehicle 1100 as status information indicating the real-time production status of vehicle 1100. In this case, the production order of vehicle 1100 becomes, for example, the information described in detail later. Figure 3 Order 1 in the list.

[0036] When the real-time production status of vehicle 1100 is at the start of production, electronic tag 1200 is associated with the production order of vehicle 1100. For example, the ID of electronic tag 1200 can be manually entered into the production order of vehicle 1100 by relevant personnel. Or, more preferably, the detection device at point P0 reads the ID of electronic tag 1200 and writes it into the production order of vehicle 1100. In this case, the ID of electronic tag 1200 is the association information indicating whether the production order of vehicle 1100 is associated with electronic tag 1200. If the production order of vehicle 1100 includes the ID of electronic tag 1200, the production order of vehicle 1100 is considered to be associated with electronic tag 1200; if the production order of vehicle 1100 does not include the ID of electronic tag 1200, the production order of vehicle 1100 is considered not associated with electronic tag 1200 or to be unassociated with electronic tag 1200. After the inspection equipment writes the ID of the electronic tag 1200 into the production order of vehicle 1100, the information indicating the production status in the production order of vehicle 1100 can be changed accordingly to information indicating that vehicle 1100 is being produced (e.g., writing "in production" in text form, or changing the code indicating the production status to a code indicating that production is in progress). In this case, the production order of vehicle 1100 becomes, for example, as will be described in detail later. Figure 3 Order 2 in the list.

[0037] When the real-time production status of vehicle 1100 begins, information related to vehicle 1100 is written to electronic tag 1200. For example, the detection equipment at point P0 can read information related to vehicle 1100 from the order of vehicle 1100 and write this information to the storage module of electronic tag 1200. After the information related to vehicle 1100 is written to electronic tag 1200, electronic tag 1200 is attached to vehicle 1100, for example, by adhesive. For example, electronic tag 1200 is manually attached to vehicle 1100 by relevant personnel at point P0, or more preferably, a robotic arm capable of attaching electronic tag 1200 can be set at point P0, and the robotic arm attaches electronic tag 1200 to vehicle 1100. During the subsequent production process, until the end of production, electronic tag 1200 remains attached to vehicle 1100 and moves with vehicle 1100.

[0038] After the electronic tag 1200 is attached to the vehicle 1100, such as Figure 1 As shown by the solid black line with arrows, vehicle 1100 and electronic tag 1200 leave point P0 and move along production line 1310, with vehicle 1100 entering the assembly stage. The assembly stage of vehicle 1100 is, for example, in... Figure 1The assembly process takes place in assembly area 1300. During the assembly phase, for example, vehicle 1100 is assembled using production line 1310 in assembly area 1300. For example, whenever vehicle 1100 arrives at an assembly position, a detection device installed at that position detects electronic tag 1200 and can identify the position of electronic tag 1200. If electronic tag 1200 is detected, the assembly equipment at that position can be activated to assemble the corresponding component onto vehicle 1100. If electronic tag 1200 is damaged or lost, or the assembly equipment malfunctions, or electronic tag 1200 is not detected by the detection device, the assembly equipment cannot be properly activated, causing an abnormality in production line 1310. When an abnormality occurs in production line 1310, an anomaly can be recorded. The position identification of electronic tag 1200 and the anomaly recording of production line 1310 will be described in detail later. The following continues to describe the case where electronic tag 1200 is not damaged or lost.

[0039] When vehicle 1100 reaches point P1 along production line 1310, the assembly of vehicle 1100 is complete. At this point, vehicle 1100 becomes an assembled vehicle. After the assembly of vehicle 1100 is completed, as follows... Figure 1 As shown by the solid black line with arrows, vehicle 1100 and electronic tag 1200 leave point P1 and enter test area 1400, and vehicle 1100 enters the test phase.

[0040] During the testing phase, vehicle 1100 travels, for example, along test route 1410 to test various functions of vehicle 1100. Electronic tag 1200 may be lost in test area 1400; for example, electronic tag 1200 may detach from vehicle 1100 and fall into test area 1400 or inside vehicle 1100 (e.g., under the seat). Furthermore, electronic tag 1200 may also be damaged during the testing phase due to the test environment, test items, etc. Using the management method of this disclosure, it is possible to determine whether an electronic tag is lost or damaged; this process will be described in detail later. The following continues to describe the case where electronic tag 1200 is not lost or damaged.

[0041] After the test of vehicle 1100 is completed, as Figure 1As shown by the solid black line with arrows, vehicle 1100 and electronic tag 1200 leave the test area 1400 and enter the electronic tag reset area 1500, marking the end of production for vehicle 1100. At this point, the real-time production status of vehicle 1100 changes to "production completed." For example, the arrival of vehicle 1100 and electronic tag 1200 at point P2 in the electronic tag reset area 1500 can be considered the end of production for vehicle 1100, and the time of arrival at point P2 can be used as the production completion time. For example, the time of arrival of vehicle 1100 at point P2 can be manually recorded by relevant personnel at point P2 as the production completion time F2 Time, or more preferably, the time when vehicle 1100 is detected by the detection equipment at point P2 can be recorded as the production completion time F2 Time. At this time, for example, the detection equipment can read the production order of vehicle 1100 from the order database, changing the information indicating the production status in the production order of vehicle 1100 to information indicating the end of production for vehicle 1100 (e.g., writing "production completed" in text form, or changing the code indicating the production status to the code indicating the end of production). Alternatively, the detection equipment can write the recorded production end time F2 Time into the production order of vehicle 1100 as status information indicating the real-time production status of vehicle 1100.

[0042] Note that, although from Figure 1 The solid black line with arrows indicates that electronic tag 1200 has reached point P2. However, as mentioned above, electronic tag 1200 may be lost before the completion of production of vehicle 1100. In this case, electronic tag 1200 cannot reach point P2. Therefore, the completion of production of vehicle 1100 cannot be determined based on whether electronic tag 1200 has reached point P2, but rather on whether vehicle 1100 itself has reached point P2. For example, the detection device at point P2 identifies the identification information (e.g., vehicle identification number) on vehicle 1100 and finds the production order corresponding to that identification information from the order database, thereby writing or changing the status information indicating the real-time production status of vehicle 1100 in the production order as described above. The following continues to describe the case where electronic tag 1200 is not lost (or damaged).

[0043] When the real-time production status of vehicle 1100 is at the end of production, electronic tag 1200 is removed from vehicle 1100. For example, electronic tag 1200 is manually removed from vehicle 1100 by personnel at point P2 and placed in the reset device at point P2. Alternatively, more preferably, a robotic arm capable of picking up electronic tag 1200 can be set up at point P2, which removes electronic tag 1200 from vehicle 1100 and places it in the reset device at point P2.

[0044] When the real-time production status of vehicle 1100 is at the end of production, after electronic tag 1200 is placed in the reset device, the information related to vehicle 1100 in electronic tag 1200 is cleared, and in response to the clearing of electronic tag 1200, the production order is deassociated with electronic tag 1200. For example, the reset device clears the information related to vehicle 1100 stored in the storage module of electronic tag 1200, and puts electronic tag 1200 into sleep mode after successful clearing, thereby resetting electronic tag 1200. Furthermore, in response to the clearing of electronic tag 1200, the reset device also reads the production order of vehicle 1100 from the order database, changing the association information in the production order that indicates whether the production order of vehicle 1100 is associated with electronic tag 1200 to indicate that the production order of vehicle 1100 is deassociated with electronic tag 1200. For example, the reset device can delete the ID of electronic tag 1200 in the production order, thus changing the ID of electronic tag 1200 in the production order to "Null". At this point, the association information indicating whether the production order for vehicle 1100 is associated with electronic tag 1200 is "Null," and the production order for vehicle 1100 is deassociated with electronic tag 1200. In this case, the production order for vehicle 1100 becomes, for example, as will be described in detail later. Figure 3 Order 3 in the list.

[0045] It can be seen that if electronic tag 1200 is lost when the real-time production status of vehicle 1100 is at the end of production, electronic tag 1200 cannot be reset because it cannot reach point P2 with vehicle 1100, and therefore cannot be unassociated with vehicle 1100. Furthermore, even if electronic tag 1200 reaches point P2, if it is damaged and cannot be reset, it also cannot be unassociated with vehicle 1100. In this case, the production order for vehicle 1100 still includes the ID of electronic tag 1200. In this situation, the production order for vehicle 1100 would, for example, become [the following will be described in detail later] Figure 3 Order 4. The following continues the description of the situation where electronic tag 1200 is not lost or damaged.

[0046] After the information related to vehicle 1100 in electronic tag 1200 is cleared and electronic tag 1200 is delinked from the production order of vehicle 1100, such as Figure 1As shown by the solid black line with arrows, the electronic tag 1200 is returned from point P2 to point P0 in the assembly area 1300 for recycling, repeating the process from point P0 to point P2 as described above. In some embodiments, to prevent the electronic tag 1200 from failing to be reset at point P2 (the information related to the vehicle 1100 in the electronic tag 1200 not being successfully cleared), a reset device capable of clearing the contents stored in the electronic tag 1200 is also installed at point P0 to reset the electronic tag 1200 again. The reset device at point P0 may have the same function as the reset device at point P2 and perform the same operation as the reset device at point P2.

[0047] Note that at point P2, sometimes to improve the management efficiency of vehicle 1100, operations such as vehicle 1100 inspection, removal and clearing of electronic tags 1200, and unlinking of electronic tags 1200 from vehicle 1100 orders may be performed simultaneously. Clearing electronic tags 1200 usually takes some time, such as 1 hour.

[0048] In addition, the above references Figure 1 The specific devices (such as detection devices, assembly devices, and reset devices) involved in the use of the described electronic tag 1200 are merely examples. These devices may belong to the same system (e.g., a management system according to this disclosure) and be under overall control, or they may be separate devices that do not require overall control. The functions of each device (the various functions described above and others described below) may also be implemented by multiple different devices. In this document, it is sufficient that the various functions described can be implemented by these devices, without limiting the specific configuration of these devices.

Vehicle-based electronic tag management method

[0050] As previously mentioned, during the production process of a vehicle (e.g., vehicle 1100), especially during the vehicle testing phase, electronic tags (e.g., electronic tag 1200) may be lost or damaged. The vehicle-based electronic tag management method (hereinafter sometimes simply referred to as the "management method") according to this disclosure enables the timely detection of lost or damaged electronic tags, thereby helping to improve the management details of vehicle production and saving time and costs. The following will refer to... Figure 2 The accompanying diagrams describe this vehicle-based electronic tag management method.

[0051] Figure 2 This is an exemplary flowchart 20 of some processes in a vehicle-based electronic tag management method according to embodiments of the present disclosure. The following uses... Figure 1 Taking application scenario 10 as an example and combining it with Figure 3 Let me describe in detail each step of flowchart 20.

[0052] First, in step S2100, information related to the production orders of vehicle 1100 is obtained. For example, in some embodiments, the order database can be automatically read at fixed time intervals (e.g., 1 hour) to obtain a list of production orders, including the production orders of vehicle 1100, thereby obtaining information related to the production orders of vehicle 1100. Alternatively, in some embodiments, the database storing the production orders of vehicle 1100 can be read after a predetermined time (e.g., 8 hours) after the production of vehicle 1100 ends, to obtain either a list of production orders including the production orders of vehicle 1100 or only the production orders of vehicle 1100, thereby obtaining information related to the production orders of vehicle 1100. Specifically, for example, a timer can be set at the end of the production of vehicle 1100 (e.g., as mentioned above, at F2 Time), and after the predetermined time has elapsed, the action of obtaining the list of production orders including the production orders of vehicle 1100 or the production orders of vehicle 1100 can be automatically triggered.

[0053] In some embodiments, the information related to the production order of vehicle 1100 includes status information indicating the real-time production status of vehicle 1100 and association information indicating whether the production order of vehicle 1100 is associated with electronic tag 1200. See below for further details. Figure 3 Detailed information regarding the production order for vehicle 1100.

[0054] Figure 3 This is an exemplary diagram of a vehicle production order list 30 according to an embodiment of the present disclosure. Figure 3 In the production order list 30, there are four orders with order numbers 1 to 4, and there is status information 3100 indicating the real-time production status of the vehicle and association information 3200 indicating whether the production order of the vehicle is associated with the electronic tag.

[0055] Status information 3100 may include, for example, three columns: "Production Status," "F0 Time," and "F2 Time." The "Production Status" column indicates the production status of the vehicle corresponding to each order, including three statuses: "Production Started," "Production in Progress," and "Production Completed." "F0 Time" and "F2 Time" are the production start time and production end time of the vehicle, respectively, as described above. Associated information 3200 may include, for example, a "Tag ID" column indicating the ID of the electronic tag. The specific writing method for the contents of the four columns—"Production Status," "F0 Time," "F2 Time," and "Tag ID"—has been described in the preceding section on electronic tags and their application examples, and will not be repeated here. A "Null" value in list 30 indicates that the content of that section is empty, that is, the content of that section has not been written or has been cleared.

[0056] Note that although the status information 3100 in the production order list 30 includes three columns: “Production Status”, “F0 Time”, and “F2 Time”, in some embodiments, the status information 3100 may only include the “Production Status” column, while in other embodiments, the status information 3100 may only include the “F0 Time” and “F2 Time” columns.

[0057] Assume the current time is 10:00 AM on May 19, 2021. Order 1's production status is "Production Started," "F0Time" is 10:00 AM on May 19, 2021, and both "F2 Time" and "Tag ID" are empty. This means that at the current time, the production status of the vehicle corresponding to Order 1 is "Production Started," the start time is the current time, but the production of this vehicle has not yet ended, and Order 1 has not yet been associated with an electronic tag. Order 1, for example, corresponds to the production order when vehicle 1100 and electronic tag 1200 arrive at point P0.

[0058] Order 2's production status is "In Production," "F0 Time" is 10:00 AM on May 17, 2021, "F2 Time" is empty, and "Tag ID" is 100.80.73.1. This means that at the current time, the vehicle corresponding to Order 2 is in production, production started two days ago, and production of this vehicle has not yet ended. Order 2 is associated with the electronic tag with ID 100.80.73.1. For example, Order 2 corresponds to a production order placed after vehicle 1100 was associated with electronic tag 1200 but before the production of vehicle 1100 was completed.

[0059] Order 3's production status is "Production Completed," "F0 Time" is 10:00 AM on May 15, 2021, "F2 Time" is 10:00 AM on May 19, 2021, and "Tag ID" is empty. This means that at the current time, the production status of the vehicle corresponding to Order 3 is "Production Completed," production started four days ago, and ended at the current time. Furthermore, Order 3 has been delinked from the electronic tag. For example, Order 3 corresponds to the production order after vehicle 1100 was delinked from electronic tag 1200.

[0060] Order 4's production status is "Production Completed," with "F0 Time" at 10:00 AM on May 13, 2021, "F2 Time" at 10:00 AM on May 17, 2021, and "Tag ID" at 100.50.34.5. This means that at the current time, the vehicle corresponding to Order 4 is in the "Production Completed" status, with production starting six days ago and ending two days ago, and Order 4 is still associated with the electronic tag with ID 100.50.34.5. Order 4, for example, corresponds to a production order that cannot be deassociated with electronic tag 1200 due to its loss or damage.

[0061] Return to Figure 2 The description is as follows. In step S2200, based on the status information and associated information included in the information related to the production order of vehicle 1100, it is determined whether the electronic tag 1200 is lost or damaged.

[0062] In some embodiments, if the status information included in the information related to the production order of vehicle 1100 indicates that the real-time production status of vehicle 1100 is that production of vehicle 1100 has been completed, and the association information indicates that electronic tag 1200 is associated with the production order of vehicle 1100, then it is determined that electronic tag 1200 is lost or damaged. Determining whether electronic tag 1200 is lost or damaged in this way allows for timely detection of any loss or damage to electronic tag 1200, and enables timely implementation of appropriate measures to locate or repair electronic tag 1200.

[0063] Specifically, assuming the production order for vehicle 1100 is... Figure 3Order 4 in the database. For example, the production order list 30, including the production order for vehicle 1100 (order 4), is retrieved at the current time by automatically reading the order database at fixed time intervals (e.g., 1 hour). In order 4, the "Production Status" in the status information 3100 is "Production Completed," indicating that the real-time production status of vehicle 1100 is that production of vehicle 1100 is completed (or it can be known from the fact that "F2 Time" has been written that the real-time production status of vehicle 1100 is that production of vehicle 1100 is completed), while the "Tag ID" in the association information 3200 has not been cleared, indicating that electronic tag 1200 is still associated with the production order of vehicle 1100. In this case, the status information indicates that the production of vehicle 1100 is completed, while the association information indicates that electronic tag 1200 has not been unassociated from the production order of vehicle 1100, thus indicating that electronic tag 1200 has not been cleared. Therefore, it can be determined that electronic tag 1200 may be lost (e.g., not placed in the reset device) or damaged (e.g., although placed in the reset device, it was not successfully cleared).

[0064] As mentioned earlier, clearing the electronic tag 1200 takes a certain amount of time. Before the electronic tag 1200 is cleared, the status information in the information related to the production order of vehicle 1100 may have already indicated that the production of vehicle 1100 has ended. However, since the electronic tag 1200 has not yet been cleared, the status information in the information related to the production order of vehicle 1100 indicates that the production order of vehicle 1100 is still associated with the electronic tag 1200. Considering this factor, in some embodiments, the method described above, of automatically acquiring the information related to the production order of vehicle 1100 after a predetermined time has elapsed since the end of the production of vehicle 1100, can be adopted. For example, acquiring the information related to the production order of vehicle 1100 at a timed interval of 8 hours after the end of the production of vehicle 1100, and determining whether the electronic tag 1200 is lost or damaged in the above manner, can make the determination result more accurate. Alternatively, the following methods can also be used to more accurately determine whether the electronic tag 1200 is lost or damaged.

[0065] In some embodiments, if the status information included in the information related to the production order of vehicle 1100 indicates that the production of vehicle 1100 has ended beyond a predetermined time threshold and the association information indicates that electronic tag 1200 is associated with the production order of vehicle 1100, then it is determined that electronic tag 1200 is lost or damaged. The time threshold can be set by relevant personnel based on experience. For example, assuming that the clearing time of electronic tag 1200 at point P2 is 1 hour and the time to transport electronic tag 1200 from point P2 back to point P0 is 1 hour, then the time threshold can be set to a time threshold greater than 2 hours. Determining whether electronic tag 1200 is lost or damaged in this way makes the determination more accurate, enabling timely detection of the loss or damage of electronic tag 1200 and timely implementation of appropriate measures to find or repair electronic tag 1200.

[0066] Specifically, assuming that the order database is automatically read at fixed time intervals (e.g., every hour), a production order list 30, including the production order for vehicle 1100 (order 4), is retrieved at the current time, and assuming a predetermined time threshold of 8 hours, in order 4, the "F2 Time" in status information 3100 is two days ago (48 hours ago), indicating that production of vehicle 1100 ended more than 8 hours ago. However, the "Tag ID" in association information 3200 has not been cleared, indicating that electronic tag 1200 is still associated with the production order for vehicle 1100. In this case, it can be determined that electronic tag 1200 is lost or damaged.

[0067] During the assembly phase of vehicle 1100, multiple vehicles are produced simultaneously on production line 1310. Identifying the location of each vehicle on production line 1310 at this time facilitates vehicle production management. Furthermore, during the assembly phase of vehicle 1100, production line 1310 sometimes experiences abnormal conditions. For example, as mentioned earlier, when electronic tag 1200 is damaged or lost, or assembly equipment malfunctions, or electronic tag 1200 is not detected by the detection equipment, the assembly equipment on production line 1310 cannot be properly activated, leading to abnormal conditions on production line 1310.

[0068] In some embodiments, the vehicle-based electronic tag management method further includes processing related to electronic tag location identification and production line anomaly recording. Such a management method can identify the location of each vehicle on the production line by recognizing the position of the electronic tag on the production line, and automatically record anomaly data related to abnormal conditions on the production line. Therefore, it facilitates vehicle production management, saves time and costs required for recording anomaly data and analyzing the causes of anomalies, and facilitates production line improvement or maintenance. The following will refer to… Figure 4 and Figure 5This section describes in detail the processing related to location identification and anomaly recording included in the vehicle-based electronic tag management method.

[0069] Figure 4 This is an exemplary flowchart 40 of some other processes in a vehicle-based electronic tag management method according to embodiments of the present disclosure. The following continues to use... Figure 1 Taking application scenario 10 as an example and combining it with Figure 5 Let’s describe each step in flowchart 40 in detail.

[0070] First, in step S4100, the position of the electronic tag 1200 on the production line 1310 of the vehicle 1100 is identified in order to perform processing related to position identification.

[0071] In some embodiments, during position identification, the position of the electronic tag 1200 on the production line 1310 is identified based on the detection of the electronic tag 1200 by a position sensor (not shown) in the production line 1310. The position sensor in the production line 1310 may be the detection equipment itself in the production line 1310 as described above, or it may be a component included in the detection equipment. Hereinafter, the example of the position sensor being a component included in the detection equipment will be used for illustration.

[0072] Position sensors are installed at a high position within production line 1310, such as on the ceiling above production line 1310, to detect electronic tag 1200 and identify the position of electronic tag 1200 (and the vehicle 1100 to which it is attached) on production line 1310. For example, two or more position sensors can be used to detect electronic tag 1200 in real time, so that its position can be accurately identified even if electronic tag 1200 is moving on production line 1310. After the position sensor detects electronic tag 1200, the detection device sends the identified position of electronic tag 1200 to a database storing the positions of electronic tags (hereinafter sometimes simply referred to as the "position database"). In the position database, the position of electronic tag 1200 is stored as a position log of electronic tag 1200, for example, associated with the ID of electronic tag 1200 and the time when the position was identified. Furthermore, in this way, the positions of other electronic tags on production line 1310 can be identified, and the position log of each electronic tag can be stored in the position database.

[0073] Note that since position sensors are usually installed at the assembly location where the assembly equipment is located, unless otherwise specified in this article, the position of the electronic tag on the production line corresponds to the assembly location where the assembly equipment is installed.

[0074] In some embodiments, a visual map of one or more vehicles being produced on production line 1310 is generated based on the locations of one or more identified electronic tags on production line 1310. The process of generating the visual map is illustrated using vehicle 1100 and electronic tag 1200 as an example. For instance, when it is desired to generate a visual map for a specific time (e.g., the current time or a past time), the location log of electronic tag 1200 can be read from a location database to obtain the location of electronic tag 1200 at that time as the location of vehicle 1100 at that time. Alternatively, information related to vehicle 1100 in the production order of vehicle 1100 associated with electronic tag 1200 can be read from an order database (e.g., based on the ID of electronic tag 1200), and a visual model of vehicle 1100 can be generated (or retrieved from a database storing visual models of vehicles) based on this information. The visual model of vehicle 1100 can be a two-dimensional or three-dimensional visual model with an appearance and parameters corresponding to vehicle 1100. The visual model of vehicle 1100 is then displayed on a pre-generated map of production line 1310. In this way, a visual model of each vehicle being produced on production line 1310 can be displayed on a map of production line 1310, thereby generating a visual map of one or more vehicles being produced on production line 1310. This visual map is not limited to a static map; it can also be a dynamic map that changes dynamically based on the real-time location of one or more vehicles. Such a visual map allows for an intuitive understanding of the production progress of vehicles on the production line, facilitating monitoring and management of vehicle production.

[0075] Specific examples of visualized maps Figure 5 As shown. Figure 5 This is an exemplary visualization map 50 of one or more vehicles being produced on a production line, according to embodiments of the present disclosure. The visualization map 50 includes a map 5100 of the production line (e.g., a portion of production line 1310) and visualization models 5200 of multiple vehicles. It can be seen that... Figure 5 The visual model 5200 of the vehicle in the visualization map 50 has the same appearance as the corresponding vehicle. Optionally, when a visual model 5200 of a certain vehicle in the visualization map 50 is selected, various parameters, production status, department, etc. of the vehicle can be displayed accordingly.

[0076] Return to Figure 4 The description is as follows. In step S4200, abnormal data related to the abnormal condition of production line 1310 is recorded, and the abnormal data is associated with the position of the electronic tag 1200 on production line 1310 when the abnormal condition occurred, in order to perform processing related to the abnormal record. This process will be described in detail below.

[0077] As previously described, for example, when the electronic tag 1200 is detected by the detection equipment in production line 1310, the assembly equipment at the corresponding location can be activated to begin operation. Specifically, for example, when the electronic tag 1200 arrives at a certain assembly position, the detection equipment at that position detects the electronic tag 1200 and reads its ID. Based on the ID of the electronic tag 1200, the detection equipment reads the production order of the vehicle 1100 associated with the electronic tag 1200 from the order database, obtains the component that needs to be assembled at that position for the vehicle 1100 from the production order, and then sends an instruction to the assembly equipment at that position to activate the assembly equipment to assemble the component into the vehicle 1100. Producing the vehicle 1100 in this way can improve the level of automation in production and facilitate the management of the production process. However, if the electronic tag 1200 is damaged or lost, or the assembly equipment in production line 1310 malfunctions, or the electronic tag 1200 is not detected by the detection equipment in production line 1310 (due to obstruction, etc.), the assembly equipment cannot be activated correctly, causing an abnormal situation in production line 1310.

[0078] In some embodiments, abnormal conditions of production line 1310 include errors in production line 1310 and production line 1310 shutdown. An error in production line 1310 may refer to an assembly device in production line 1310 failing to operate correctly due to not being properly activated. For example, the assembly device may assemble the wrong part due to its own malfunction or the assembly accuracy may not meet requirements. Or, for example, the detection device may send incorrect instructions due to a damaged electronic tag 1200, causing the assembly device to perform incorrect assembly actions. Production line 1310 shutdown may refer to the entire production line 1310 stopping for a period of time due to the inactivation of assembly equipment in production line 1310. For example, if the electronic tag 1200 is lost or not detected by the detection device due to obstruction, the assembly equipment at the corresponding location cannot be activated, preventing assembly at that location from being performed. Furthermore, to prevent confusion between different assembly processes of the same vehicle or between different vehicles, all assembly equipment in the entire production line 1310 may be forcibly suspended. Such abnormal conditions of production line 1310 may only last a few seconds or less, but can still cause losses.

[0079] In some embodiments, abnormal data of production line 1310 is obtained from production line 1310 when an abnormal condition occurs. When the aforementioned abnormal condition occurs on production line 1310, the assembly equipment and / or detection equipment at the location causing the abnormal condition will generate abnormal data. The abnormal data includes, for example, the time of occurrence of the abnormal condition, a fault code, and the duration of the abnormal condition. For example, when an abnormal condition is caused by a malfunction of the assembly equipment, abnormal data corresponding to the abnormal condition will be generated in the assembly log of the assembly equipment. Or, for example, when the detection equipment cannot detect the electronic tag 1200 due to damage or loss, or because the electronic tag 1200 is obstructed, abnormal data corresponding to the abnormal condition will be generated in the detection log of the detection equipment. Thus, when an abnormal condition occurs on production line 1310, abnormal data related to the abnormal condition of production line 1310 can be obtained from the assembly equipment and / or detection equipment in production line 1310.

[0080] The acquired abnormal data related to the abnormal condition of production line 1310 can be recorded, for example, in a database storing abnormal data, and the abnormal data can be associated with the location of the electronic tag 1200 when the abnormal condition of production line 1310 occurs, for further analysis of the cause of the abnormality, statistical analysis of abnormal data, production line maintenance, production management optimization, etc. The location of the electronic tag 1200 when the abnormal condition of production line 1310 occurs can be obtained from the location database described above when the abnormal condition occurs.

[0081] In some embodiments, abnormal data of the production line 1310 can be statistically analyzed for one or more locations of the electronic tag 1200 on the production line 1310. Since the location of the electronic tag 1200 on the production line 1310 corresponds to an assembly location, abnormal data of abnormal conditions occurring at one or more assembly locations can be statistically analyzed for further analysis of abnormality causes, production line maintenance, production management optimization, etc. For example, the number of abnormal conditions occurring at one or more assembly locations within a predetermined time period (e.g., one day, one week, or one month), the ratio of the number of abnormal conditions occurring at that location to the total number of abnormal conditions, the causes of the abnormal conditions at that location, the frequency or number of occurrences of each abnormal condition, the cumulative time of the abnormal conditions, and the number of abnormal conditions per production unit of vehicles can be statistically analyzed. Furthermore, corresponding statistical data at different locations can be compared to identify assembly locations with a high frequency of abnormal conditions, thereby analyzing weak points in the production process.

[0082] In some embodiments, based on the abnormal data from production line 1310, it can be determined whether electronic tag 1200 is lost or damaged. As described above, the abnormal data may include fault codes and the duration of the abnormal condition. Based on the source of the abnormal data (whether it originates from the detection equipment or the assembly equipment), the fault codes in the abnormal data, and the duration of the abnormality, it can be analyzed whether the abnormal condition is caused by the loss or damage of electronic tag 1200. For example, if the duration of the abnormal condition in the abnormal data exceeds a predetermined time threshold, the fault code indicates that the abnormal condition is caused by the failure to detect electronic tag 1200, and the source of the abnormal data is the detection equipment, it can be determined that the abnormal condition is caused by the loss of electronic tag 1200. Alternatively, for example, if the duration of the abnormal condition in the abnormal data exceeds a predetermined time threshold, the fault code indicates that the abnormal condition is caused by the detection of electronic tag 1200 but an error occurred, and the source of the abnormal data is both the detection equipment and the assembly equipment, it can be determined that the abnormal condition is caused by the damage of electronic tag 1200. Of course, these are just examples, and it is also possible to determine whether electronic tag 1200 is lost or damaged based on other information in the abnormal data. After determining that electronic tag 1200 is lost or damaged, an alarm can be issued to relevant personnel to notify them to handle the situation promptly. Determining whether the electronic tag 1200 is lost or damaged in this way enables timely measures to be taken after the electronic tag 1200 is lost, thereby avoiding or reducing losses caused by the loss or damage of the electronic tag 1200.

[0083] In some embodiments, based on anomaly data from production line 1310, the arrangement of position sensors in production line 1310 and / or maintenance of production equipment in production line 1310 can be adjusted. Production equipment in production line 1310 includes, for example, assembly equipment and inspection equipment as described above. For example, if analysis of anomaly data for a specific assembly position reveals that the frequency of anomalies caused by obstructed electronic tags at that position is high (e.g., more than twice the frequency of such anomalies at other positions), it can be assumed that the obstruction of electronic tag 1200 is due to an improper arrangement of position sensors at that position, and the arrangement of position sensors at that position can be adjusted. Alternatively, for example, if analysis of anomaly data for a specific assembly position reveals that the duration of anomalies caused by assembly equipment malfunctions at that position is long (e.g., higher than the average duration of such anomalies), it can be assumed that the assembly equipment at that position needs maintenance, and the assembly equipment at that position can be maintained. Adjusting the arrangement of position sensors and / or maintaining production equipment in production line 1310 in this way can promptly identify and address factors detrimental to production in production line 1310, thereby avoiding or reducing losses caused by abnormal conditions in the production line and improving production efficiency.

[0084] Note that the specific details of the location identification and anomaly recording processes described above are merely examples, and the execution order of each step is only required to conform to the logical order, and is not necessarily limited to the order described above. The location of the electronic tag identified through the above processing and the recorded anomaly data can also be utilized in ways different from the various utilization methods mentioned above.
