Description

Management method, management device and computer program product for vehicle-based electronic tags

Technical Field

The present disclosure relates to the field of vehicle management, and more particularly to a method, a device and a computer program product for managing a vehicle-based electronic tag.

Background

In the production process of a vehicle, in order to facilitate the production line of the vehicle to identify the vehicle being produced and produce it, an electronic tag that can be attached to the vehicle body may be used. The electronic tag can record information about the vehicle to which it is attached, such as a vehicle identification number, a vehicle model number, a production number, and the like. When the production line of the vehicle detects the electronic tag, the information related to the vehicle recorded in the electronic tag can be read, the component to be assembled next is judged, and the corresponding assembling equipment (such as an industrial robot) on the production line is activated.

The following presents a simplified summary of the disclosure in order to provide a basic understanding of some aspects of the disclosure. However, it should be understood that this summary is not an exhaustive overview of the disclosure. It is not intended to identify key or critical elements of the disclosure or to delineate the scope of the disclosure. Its sole purpose is to present some concepts of the disclosure in a simplified form as a prelude to the more detailed description that is presented later.

The inventor of the present disclosure has noted that there is a case where the electronic tag is lost or damaged during the use. For example, in a test stage after the vehicle assembly is completed, if the electronic tag is lost or damaged, the electronic tag cannot be recycled and reused. In addition, since the electronic tag is small in size and the testing stage of the vehicle is usually performed in a wide open field, it is difficult to find the loss of the electronic tag in time, thereby increasing the time and difficulty of finding the electronic tag. Thus, loss or damage to the electronic tag may be a nuisance to the production of the vehicle and cause significant time and cost losses.

The present disclosure has been made in view of the above circumstances, and an object thereof is to provide a vehicle-based electronic tag management method, a management apparatus, and a computer program product capable of automatically determining whether an electronic tag of a vehicle is lost or damaged, so that the loss or damage of the electronic tag can be timely found, thereby contributing to perfecting management details of vehicle production, saving time and cost.

Electronic tag and application example thereof

In order to facilitate better understanding of the present disclosure, an electronic tag of a vehicle and an application example thereof according to an embodiment of the present disclosure are first described with reference to fig. 1.

Fig. 1 is a schematic illustration of an application scenario 10 of an electronic tag 1200 of a vehicle 1100 according to an embodiment of the disclosure. In application scenario 10, vehicle 1100, electronic tag 1200, assembly area 1300, test area 1400, and electronic tag reset area 1500 are shown. Wherein, the assembly area 1300 includes a production line 1310, an assembly starting point P0, and an assembly ending point P1. Test area 1400 includes test routes 1410. The electronic tag reset area 1500 includes an electronic tag reset point P2. The solid black line with arrows in fig. 1 indicates the general moving path of the electronic tag. Note that, the contents described below with reference to fig. 1 refer to a case where the electronic tag 1200 is not damaged or lost, unless otherwise specified.

Vehicle 1100 may be any vehicle before shipment. Electronic tag 1200 may be attached to the body of vehicle 1100 by, for example, adhesive bonding. For example, to facilitate detection of electronic tag 1200 by a detection device (not shown) in production line 1310, electronic tag 1200 may be attached to an exterior surface of vehicle 1100, such as to a hood of vehicle 1100. Although fig. 1 shows a state where electronic tag 1200 is attached to vehicle 1100, vehicle 1100 and electronic tag 1200 may be separated from each other before production of vehicle 1100 is started and after production is completed, as described later. Further, although fig. 1 illustrates the contour of the body of the assembled vehicle 1100, the vehicle 1100 may also be a component or combination of components of a vehicle that is not fully assembled. In this context, a vehicle (e.g., vehicle 1100) may be either an incompletely assembled vehicle or a completely assembled vehicle. In the case where the vehicle is an incompletely assembled vehicle, it is intended that the component or combination of components is already assembled.

The electronic tag 1200 may be, for example, a small electronic device including a memory module and a communication module, and can be attached to the body of the vehicle 1100 by means of pasting or the like as described above. The memory module of the electronic tag 1200 may be used to store information about the vehicle 1100, such as vehicle identification number, model number, production number, etc. of the vehicle 1100. The communication module of the electronic tag 1200 for example comprises a low frequency communication circuit capable of emitting a low frequency wireless signal to enable the detection device to detect the electronic tag 1200. In addition, the communication module of the electronic tag 1200 may further transmit information stored in the storage module to the detection device, and store information received from the detection device in the storage module, so as to implement reading and writing of the electronic tag 1200. Here, a specific configuration of the electronic tag 1200 is not limited. The electronic tag 1200 is only required to be able to store information about the vehicle 1100 and to be detected by the detection device.

Assembly area 1300 is an area for performing an assembly phase of vehicle 1100, including production line 1310. The production line 1310 is used to assemble the vehicle 1100, and may include, for example, assembly equipment (e.g., robots, robotic arms, etc.), detection equipment (e.g., position sensors), conveyor belts, etc., not shown. Further, the 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 a point where assembly of vehicle 1100 is started, and is also a point where production of vehicle 1100 is started as described later. Point P1 is a point where the assembly of vehicle 1100 is completed. At points P0 and P1, for example, a detection device capable of detecting the electronic tag 1200 and recording the time when the electronic tag 1200 is detected may be installed. Preferably, the detection device at point P0 is equipped with communication functions enabling reading and writing operations of the production order of vehicle 1100 and/or electronic tag 1200. The reading and writing operations of the production order for the vehicle 1100 may be performed in such a manner that the inspection apparatus receives and transmits information from and to an apparatus that manages the production order for the vehicle 1100 (hereinafter sometimes simply referred to as "order management apparatus"), and the order management apparatus reads and writes the production order for the vehicle 1100, or in such a manner that the inspection apparatus directly reads and writes the production order for the vehicle 1100. The reading operation of the electronic tag 1200 may be performed in a manner that the detection apparatus directly performs reading and writing operations on the electronic tag 1200. In the following, the operation of reading and writing the production order of the vehicle 1100 and/or the electronic tag 1200 by the inspection equipment at point P0 is described as the operation of reading and writing the production order of the vehicle 1100 and/or the electronic tag 1200 by the inspection equipment directly, omitting possible intermediate processes.

The test area 1400 is an area for performing a test phase of the vehicle 1100, including a test route 1410. Test route 1410 is used to allow vehicle 1100, once assembled, to travel along test route 1410 to test various functions of vehicle 1100. Although a zigzag test route 1410 is shown in fig. 1, the test route 1410 does not necessarily have a fixed position and shape. Herein, the test route 1410 refers to a trajectory that the vehicle 1100 moves when being tested, that is, a trajectory that the electronic tag 1200 attached to the vehicle 1100 moves in the test area 1400. Since the test area 1400 is generally an open outdoor area, and depending on the environmental conditions at the time of testing, test items, and the like, the electronic tag 1200 may be detached from the vehicle 1100 and lost in the test area 1400.

Electronic tag reset area 1500 is an area for collecting and resetting electronic tag 1200, and includes an electronic tag reset point P2 (hereinafter sometimes simply referred to as point P2). The point P2 is a point where the electronic tag 1200 is reset, and for example, a detection device capable of detecting the vehicle 1100 and recording the time when the vehicle 1100 is detected and a reset device capable of clearing the content stored in the electronic tag 1200 may be installed. Preferably, the detection device and the reset device at point P2 are equipped with communication functions so that reading and writing operations can be performed on the production order of the vehicle 1100. As in the case of the point P0, the reading and writing operations of the production order for the vehicle 1100 may be performed directly by the detection device and the reset device, or may be performed via the order management device. In the following, the reading and writing operations of the production order of the vehicle 1100 by the inspection apparatus and the reset apparatus at the point P2 are described as the inspection apparatus and the reset apparatus directly reading and writing the production order of the vehicle 1100 with the omission of a possible intermediate process.

In this context, the production of the vehicle 1100 is generally divided into an assembly phase and a testing phase after assembly is complete. The vehicle manufacturer starts the production of the vehicle 1100, that is, the assembly phase and the test phase are sequentially performed, according to the received production order of the vehicle 1100. The production order for the vehicle 1100 may be, for example, data in any format, such as a spreadsheet, entries in a database, etc., that includes information related to the vehicle 1100 as described above. Further, as will be described later, in some embodiments, the production order for vehicle 1100 may also include status information indicating a real-time production status of vehicle 1100 and association information indicating whether the production order for vehicle 1100 is associated with electronic tag 1200.

Herein, the start of assembly of the vehicle 1100 is taken as the start of production of the vehicle 1100, the end of testing of the vehicle 1100 is taken as the end of production of the vehicle 1100, and the state of the vehicle 1100 from the start of assembly to the end of production is taken as being produced. Thus, herein, the real-time production status of the vehicle 1100 includes the production start (assembly start), the production (assembly, assembly end, or testing) and the production end (testing end) of the vehicle 1100.

In some embodiments, when the real-time production state of vehicle 1100 is the production start of vehicle 1100, electronic tag 1200 is associated with the production order of vehicle 1100, information about vehicle 1100 is written into 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, information in electronic tag 1200 related to vehicle 1100 is emptied, and in response to the emptying of electronic tag 1200, the production order is disassociated from electronic tag 1200. The process is described in detail below with reference to fig. 1 in connection with the production of the vehicle 1100 and the movement of the electronic tag 1200.

After the vehicle manufacturer receives a production order for the vehicle 1100, the vehicle 1100 is prepared for the original assembled components (e.g., hood) and the electronic tag 1200, respectively, to which information about any vehicle has not been written. Then, the vehicle 1100 and the electronic tag 1200 respectively reach the point P0 in the mounting area 1300 in a state of being separated from each other.

At point P0, production of vehicle 1100 begins. At this time, the real-time production state of the vehicle 1100 is the production start of the vehicle 1100. For example, the Time when the electronic tag 1200 reaches the point P0 and is detected may be recorded as the production start Time (i.e., assembly start Time) F0 Time of the vehicle 1100 by the detection device of the point P0. At this time, for example, it is possible to read the production order of the vehicle 1100 from a database (hereinafter sometimes referred to as "order database") in which the production order is stored, and change the information indicating the production state in the production order of the vehicle 1100 to the information indicating the production start of the vehicle 1100 (for example, write the "production start" in a text form, or change the code indicating the production state to the code indicating the production start), by the inspection apparatus. Alternatively or additionally, the recorded production start Time F0 Time may be written by the detection device into the production order for the vehicle 1100 as the status information indicating the real-Time production status of the vehicle 1100. In this case, the production order of the vehicle 1100 becomes, for example, order 1 in fig. 3, which will be described later in detail.

When the real-time production state of the vehicle 1100 is the production start of the vehicle 1100, the electronic tag 1200 is associated with the production order of the vehicle 1100. For example, the ID of the electronic tag 1200 may be manually entered into a production order for the vehicle 1100 by the relevant personnel. Or more preferably, the ID of the electronic tag 1200 is read by the detection device at point P0 and written into the production order for the vehicle 1100. In this case, the ID of the electronic tag 1200 is association information indicating whether or not the production order of the vehicle 1100 is associated with the electronic tag 1200. In the case where the ID of electronic tag 1200 is included in the production order of vehicle 1100, the production order of vehicle 1100 is considered to be associated with electronic tag 1200, and in the case where the production order of vehicle 1100 does not include the ID of electronic tag 1200, the production order of vehicle 1100 is considered to be unassociated with electronic tag 1200 or disassociated from electronic tag 1200. After the detection device writes the ID of the electronic tag 1200 to the production order of the vehicle 1100, the information indicating the production status in the production order of the vehicle 1100 may be changed to the information indicating that the vehicle 1100 is producing accordingly (for example, "producing" is written in text, or a code indicating the production status is changed to a code indicating producing). In this case, the production order of the vehicle 1100 becomes, for example, order 2 in fig. 3, which will be described later in detail.

When the real-time production state of the vehicle 1100 is the production start of the vehicle 1100, the information about the vehicle 1100 is written in the electronic tag 1200. For example, information about the vehicle 1100 may be read from an order for the vehicle 1100 by the detection device at point P0 and written to the memory module of the electronic tag 1200. After the information about the vehicle 1100 is written in the electronic tag 1200, the electronic tag 1200 is attached to the vehicle 1100, for example, in a pasted manner. For example, the electronic tag 1200 is manually attached to the vehicle 1100 by the relevant person at the point P0, or more preferably, a robot arm capable of attaching the electronic tag 1200 may be provided at the point P0, by which the electronic tag 1200 is attached to the vehicle 1100. In the production process thereafter, the electronic tag 1200 is attached to the vehicle 1100 and moved together with the vehicle 1100 until the end of the production.

After the electronic tag 1200 is attached to the vehicle 1100, as shown by the solid black line with an arrow in fig. 1, the vehicle 1100 and the electronic tag 1200 move away from the point P0 along the production line 1310, and the vehicle 1100 enters the assembly stage. The assembly phase of vehicle 1100 is performed, for example, in assembly area 1300 in fig. 1. At the assembly stage, vehicle 1100 is assembled, for example, using production line 1310 in assembly area 1300. For example, each time the vehicle 1100 reaches an assembly position, the detection device installed at the position detects the electronic tag 1200 and enables position recognition of the electronic tag 1200. In the case where the electronic tag 1200 is detected, the assembling device at the position may be activated to assemble the corresponding component to the vehicle 1100. If the electronic tag 1200 is damaged or lost, or the assembly device fails, or the electronic tag 1200 is not detected by the detection device, the assembly device cannot be properly activated, resulting in an abnormal condition in the production line 1310. When an abnormal condition occurs in the production line 1310, an abnormality record can be made. The location identification of the electronic tag 1200 and the exception recording of the production line 1310 will be described in detail later. The following continues to describe the case where the electronic tag 1200 is not damaged or lost.

The assembly of vehicle 1100 is complete when vehicle 1100 reaches point P1 along production line 1310. At this time, vehicle 1100 becomes an assembled vehicle. After the vehicle 1100 is assembled, as shown by the solid black line with an arrow in fig. 1, the vehicle 1100 and the electronic tag 1200 leave the point P1 and enter the test area 1400, and the vehicle 1100 enters the test phase.

In the testing phase, the vehicle 1100 is driven, for example, along a test route 1410 to test various functions of the vehicle 1100. The electronic tag 1200 may be lost in the test area 1400, for example, the electronic tag 1200 may be detached from the vehicle 1100, may fall into the test area 1400, and may also fall inside the vehicle 1100 (e.g., under a seat). In addition, the electronic tag 1200 may also be damaged during the testing phase due to the testing environment, the testing items, and the like. With the management method of the present disclosure, it is possible to determine whether the electronic tag is lost or damaged, which will be described in detail later. The following continues to describe the situation where the electronic tag 1200 is not lost or damaged.

After the test of the vehicle 1100 is completed, as shown by the solid black line with an arrow in fig. 1, the vehicle 1100 and the electronic tag 1200 leave the test area 1400 and enter the electronic tag reset area 1500, and the production of the vehicle 1100 is completed. At this time, the real-time production state of the vehicle 1100 becomes the end of production. For example, point P2 at which vehicle 1100 and electronic tag 1200 reach electronic tag reset area 1500 may be regarded as the production end of vehicle 1100, and the time at which point P2 is reached may be regarded as the production end time. For example, the Time at which the vehicle 1100 reaches the point P2 may be manually recorded as the production end Time F2 Time by a person related to the point P2, or more preferably, the Time at which the vehicle 1100 is detected by the detection device of the point P2 may be recorded as the production end Time F2 Time. At this time, for example, the production order of the vehicle 1100 may be read from the order database by the inspection apparatus, causing the information indicating the production state in the production order of the vehicle 1100 to be changed to the information indicating the production end of the vehicle 1100 (for example, "production end" is written in a text form, or a code indicating the production state is changed to a code indicating the production end). Alternatively, the recorded production end Time F2 Time may also be written by the detection apparatus into the production order of the vehicle 1100 as the status information indicating the real-Time production status of the vehicle 1100.

Note that although the electronic tag 1200 reaches the point P2 as seen from the solid black line with an arrow in fig. 1, the electronic tag 1200 may be lost before the end of production of the vehicle 1100 as described above, and in this case, the electronic tag 1200 cannot reach the point P2. Therefore, the end of production of the vehicle 1100 cannot be determined based on whether the electronic tag 1200 reaches the P2 point, but based on whether the vehicle 1100 itself reaches the P2 point. For example, the inspection apparatus at the point P2 recognizes identification information (e.g., vehicle identification number) on the vehicle 1100 and finds a production order corresponding to the identification information from the order database, thereby writing or changing status information indicating a real-time production status of the vehicle 1100 in the production order as described above. The following description is continued for the case where the electronic tag 1200 is not lost (or damaged).

When the real-time production state of the vehicle 1100 is the end of production of the vehicle 1100, the electronic tag 1200 is removed from the vehicle 1100. For example, the electronic tag 1200 is removed from the vehicle 1100 by a person concerned at the point P2 manually, and the electronic tag 1200 is placed in the reset device at the point P2. Or more preferably, a robot arm capable of picking up the electronic tag 1200 may be provided at the point P2, the electronic tag 1200 is removed from the vehicle 1100 by the robot arm, and the electronic tag 1200 is placed in the reset device at the point P2.

When the real-time production state of the vehicle 1100 is the end of production of the vehicle 1100, after the electronic tag 1200 is placed in the reset device, the information about the vehicle 1100 in the electronic tag 1200 is emptied, and the production order is disassociated from the electronic tag 1200 in response to the emptying of the electronic tag 1200. For example, the information about the vehicle 1100 stored in the storage module of the electronic tag 1200 is cleared by the reset device, and the electronic tag 1200 is put to sleep after the clearing is successful, thereby resetting the electronic tag 1200. Further, in response to the emptying of the electronic tag 1200, the reset device also reads the production order of the vehicle 1100 from the order database, causing the association information in the production order indicating whether the production order of the vehicle 1100 is associated with the electronic tag 1200 to change to indicate that the production order of the vehicle 1100 is disassociated from the electronic tag 1200. For example, the reset device may delete the ID of the electronic tag 1200 in the production order to change the ID of the electronic tag 1200 in the production order to "Null". At this time, the association information indicating whether the production order of the vehicle 1100 is associated with the electronic tag 1200 is "Null", and the production order of the vehicle 1100 is disassociated from the electronic tag 1200. In this case, the production order of the vehicle 1100 becomes, for example, order 3 in fig. 3 which will be described later in detail.

It can be seen that if electronic tag 1200 is lost when the real-time production status of vehicle 1100 is the end of production of vehicle 1100, electronic tag 1200 cannot be reset because it cannot reach point P2 with vehicle 1100 and cannot be disassociated from vehicle 1100. Further, even if the electronic tag 1200 reaches the point P2, if the electronic tag 1200 cannot be reset due to damage, it cannot be disassociated from the vehicle 1100. At this time, the ID of the electronic tag 1200 is still included in the production order of the vehicle 1100. In this case, the production order of the vehicle 1100 becomes, for example, an order 4 in fig. 3 which will be described later in detail. The following continues to describe the situation where the electronic tag 1200 is not lost or damaged.

After the information on the vehicle 1100 in the electronic tag 1200 is emptied and the electronic tag 1200 is disassociated from the production order of the vehicle 1100, as indicated by the solid black line with an arrow in fig. 1, the electronic tag 1200 is returned from the point P2 to the point P0 in the assembly area 1300 to be recycled, and the process from the point P0 to the point P2 as described above is repeated. In some embodiments, in order to prevent electronic tag 1200 from being unsuccessfully reset at point P2 (information about vehicle 1100 in electronic tag 1200 is unsuccessfully cleared), a reset device capable of clearing the contents stored in electronic tag 1200 is also installed at point P0 to reset electronic tag 1200 again. The reset device at P0 point may have the same function and perform the same operation as the reset device at P2 point.

Note that at point P2, operations such as detection of vehicle 1100, removal and emptying of electronic tag 1200, and disassociation of electronic tag 1200 from an order for vehicle 1100 may be performed simultaneously, sometimes in order to improve management efficiency of vehicle 1100. The emptying of the electronic tag 1200 typically takes a period of time, e.g. 1 hour.

In addition, the respective specific devices (such as the detection device, the mounting device, the reset device) involved in the utilization process of the electronic tag 1200 described above with reference to fig. 1 are only examples. These devices may be controlled collectively by belonging to the same system (e.g., a management system according to the present disclosure), or may be separate devices that do not require overall control. The functions (the respective functions described above and the other functions described later) provided in each device may be implemented by a plurality of different devices, respectively. In this document, as long as the respective functions described are enabled by these devices, the specific configuration of these devices is not limited.

Management method of electronic tags based on vehicles

As previously discussed, during the production of a vehicle (e.g., vehicle 1100), particularly during the testing phase of the vehicle, an electronic tag (e.g., electronic tag 1200) may be lost or damaged. The management method of the vehicle-based electronic tag according to the present disclosure (hereinafter sometimes simply referred to as "management method") enables loss or damage of the electronic tag to be discovered in time, thereby contributing to perfecting management details of vehicle production, saving time and cost. A management method of such a vehicle-based electronic tag will be described below with reference to fig. 2 and subsequent drawings.

Fig. 2 is an exemplary flowchart 20 of some processes in a method of managing vehicle-based electronic tags according to an embodiment of the present disclosure. The steps of flowchart 20 are described in detail below with reference to fig. 3 and application scenario 10 in fig. 1 as an example.

First, in step S2100, information relating to a production order of the vehicle 1100 is acquired. For example, in some embodiments, the order database may be automatically read at regular time intervals (e.g., 1 hour) to obtain a list of production orders including the production orders for vehicle 1100, and thus obtain information about the production orders for vehicle 1100. In addition, in some embodiments, the information on the production order of the vehicle 1100 may also be acquired by reading a database storing the production orders of the vehicle 1100 after the production of the vehicle 1100 is ended for a predetermined time (for example, 8 hours), acquiring a production order list including the production orders of the vehicle 1100, or acquiring only the production orders of the vehicle 1100. Specifically, for example, a timer for a predetermined Time may be set at the end of production of the vehicle 1100 (e.g., at F2 Time, as previously described), and the act of obtaining a list of production orders including the production order for the vehicle 1100 or the production order for the vehicle 1100 may be automatically triggered after the predetermined Time has elapsed.

In some embodiments, the information related to the production order for the vehicle 1100 includes status information indicating a real-time production status of the vehicle 1100 and association information indicating whether the production order for the vehicle 1100 is associated with the electronic tag 1200. The information related to the production order of the vehicle 1100 is explained in detail below with reference to fig. 3.

FIG. 3 is an exemplary illustration of a production order list 30 for a vehicle according to an embodiment of the disclosure. In fig. 3, the production order list 30 includes 4 orders with order numbers 1 to 4, and includes status information 3100 indicating a 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.

The state information 3100 may include, for example, three columns, "production state", "F0 Time", and "F2 Time". The "production status" column indicates the production status of the vehicle corresponding to each order, and includes three statuses "production start", "production in progress", and "production end". "F0 Time" and "F2 Time" are the production start Time and the production end Time of the vehicle as described above, respectively. The association information 3200 may include, for example, a column of "Tag ID" indicating an ID of the electronic Tag. The specific writing modes of the contents in the four columns of "production state", "F0 Time", "F2 Time", and "Tag ID" are described in the foregoing electronic Tag and its application example section, and will not be repeated here. A content of "Null" in the list 30 indicates that the content of the portion is empty, i.e., that the content of the portion has not been written to or has been cleared.

Note that while state information 3100 in production order list 30 includes three columns, "production state," F0 Time, "and" F2 Time, "state information 3100 may, in some embodiments, include only the" production state "column, while in other embodiments, state information 3100 may include only the two columns," F0 Time, "and" F2 Time.

Assume that the current time is 2021 year 5, 19 am 10 am. The production status of order 1 is "production start", "F0 Time" is 10 am, 5/19/2021, "F2 Time" and "Tag ID" are all empty. This means that at the current time, the production state of the vehicle corresponding to the order 1 is production start, the time of production start is the current time, the production of the vehicle has not ended, and the order 1 has not been associated with the electronic tag. Order 1 corresponds to, for example, a production order when vehicle 1100 and electronic tag 1200 reach point P0.

The production status of order 2 is "producing", "F0 Time" is 10 am, 5/17/2021, "F2 Time" is empty, and "Tag ID" is 100.80.73.1. This means that at the current time, the production status of the vehicle corresponding to order 2 is production, the production starts two days ago, but the production of the vehicle has not ended, and order 2 is associated with the electronic tag having the ID of 100.80.73.1. Order 2 corresponds to, for example, a production order after vehicle 1100 is associated with electronic tag 1200 and before production of vehicle 1100 is completed.

The production status of order 3 is "end of production", "F0 Time" is 10 am, 5/15/2021, "F2 Time" is 10 am, 5/19/2021, "Tag ID" is empty. This means that at the current time, the production state of the vehicle corresponding to the order 3 is the end of production, the time four days before the start of production, the time of the end of production is the current time, and the order 3 has been disassociated from the electronic tag. Order 3 corresponds to, for example, a production order in which vehicle 1100 is disassociated from electronic tag 1200.

The production status of order 4 is "end of production", "F0 Time" is 10 am, 5/13/2021, "F2 Time" is 10 am, 5/17/2021, "Tag ID" is 100.50.34.5. This means that at the current time, the production state of the vehicle corresponding to order 4 is end of production, the time of production start is six days ago, the time of production end is two days ago, and order 4 is still associated with an electronic tag having an ID of 100.50.34.5. Order 4 corresponds to, for example, a production order that cannot be disassociated from electronic tag 1200 due to loss or damage to electronic tag 1200.

Returning to the description of fig. 2. In step S2200, it is determined whether the electronic tag 1200 is lost or damaged, based on the status information and the associated information included in the information relating to the production order of the vehicle 1100.

In some embodiments, in the case where the status information included in the information relating to the production order of the vehicle 1100 indicates that the real-time production status of the vehicle 1100 is the end of production of the vehicle 1100 and the association information indicates that the electronic tag 1200 is associated with the production order of the vehicle 1100, it is determined that the electronic tag 1200 is lost or damaged. Determining whether the electronic tag 1200 is lost or damaged in this way can find the loss or damage of the electronic tag 1200 in time, and can take corresponding measures to find or repair the electronic tag 1200 in time.

Specifically, assume that the production order for vehicle 1100 is order 4 in FIG. 3. For example, the production order list 30 including the production order (order 4) of the vehicle 1100 is acquired at the present time in such a manner that the order database is automatically read at regular time intervals (for example, 1 hour). In order 4, "production status" in status information 3100 is "end of production", indicating that the real-Time production status of vehicle 1100 is the end of production of vehicle 1100 (or that the real-Time production status of vehicle 1100 is the end of production of vehicle 1100 as it is known from "F2 Time" that has been written), while "Tag ID" in association information 3200 is not cleared, indicating that electronic Tag 1200 is still associated with the production order of vehicle 1100. In this case, it is known from the state information that the production of the vehicle 1100 is ended, and it is known from the association information that the electronic tag 1200 is not disassociated from the production order of the vehicle 1100, indicating that the electronic tag 1200 is not emptied. Thus, it may be determined that electronic tag 1200 may be lost (e.g., not placed in a reset device) or damaged (e.g., not successfully emptied despite being placed in a reset device).

As described above, the electronic tag 1200 requires a certain time to be emptied. The status information in the information relating to the production order for vehicle 1100 may already indicate that production of vehicle 1100 is complete before electronic tag 1200 is emptied, at which time the status information in the information relating to the production order for vehicle 1100 indicates that the production order for vehicle 1100 is still associated with electronic tag 1200 because electronic tag 1200 has not yet been emptied. In view of such factors, in some embodiments, a manner may be employed in which information relating to a production order for the vehicle 1100 is automatically acquired after a predetermined time has elapsed since the end of production of the vehicle 1100, as described above. For example, acquiring information relating to a production order of the vehicle 1100 at a timing of 8 hours after the production of the vehicle 1100 is ended, and determining whether the electronic tag 1200 is lost or damaged in the above-described manner can make the determination result more accurate. Alternatively, the following manner may be employed to more accurately determine whether the electronic tag 1200 is lost or damaged.

In some embodiments, it is determined that the electronic tag 1200 is lost or damaged in the case where the status information included in the information relating to the production order of the vehicle 1100 indicates that the production of the vehicle 1100 is ended beyond a predetermined time threshold and the association information indicates that the electronic tag 1200 is associated with the production order of the vehicle 1100. The time threshold may be set empirically by the relevant person. For example, assuming that the clearing time of the electronic tag 1200 at point P2 is 1 hour and the time for transporting the electronic tag 1200 from point P2 back to point P0 is 1 hour, the time threshold may be set to a certain time threshold greater than 2 hours. Determining whether the electronic tag 1200 is lost or damaged in this way can make the determination result more accurate, so that the loss or damage of the electronic tag 1200 can be found in time and corresponding measures can be taken in time to find or repair the electronic tag 1200.

Specifically, it is still assumed that the production order list 30 including the production order (order 4) of the vehicle 1100 is acquired at the current time in such a manner that the order database is automatically read at regular time intervals (for example, 1 hour), and that the predetermined time threshold is 8 hours. In order 4, "F2 Time" in status information 3100 is two days ago (48 hours ago), indicating that production of vehicle 1100 is over 8 hours ended, while "Tag ID" in association information 3200 is not cleared, indicating that electronic Tag 1200 is still associated with the production order of vehicle 1100. In this case, it can be determined that the electronic tag 1200 is lost or damaged.

During the assembly phase of the vehicle 1100, production of multiple vehicles is simultaneously occurring on the production line 1310. At this time, if the position of each vehicle on the production line 1310 can be identified, management of vehicle production can be facilitated. Further, during the assembly stage of the vehicle 1100, an abnormal condition sometimes occurs in the production line 1310. For example, as previously described, when the electronic tag 1200 is damaged or lost, or the assembly device is malfunctioning, or the electronic tag 1200 is not detected by the detection device, the assembly device in the production line 1310 cannot be properly activated, resulting in an abnormal condition in the production line 1310.

In some embodiments, the management method of the vehicle-based electronic tag further includes processing related to position recognition of the electronic tag and abnormal recording of the production line. The management method can identify the position of each vehicle on the production line by identifying the position of the electronic tag on the production line, and automatically record abnormal data related to abnormal conditions of the production line, so that the management of the production of the vehicles can be facilitated, the time and cost required for recording the abnormal data and analyzing abnormal reasons can be saved, and the improvement or maintenance of the production line can be facilitated. The processing related to the position recognition and the abnormality record included in the management method of the vehicle-based electronic tag will be described in detail below with reference to fig. 4 and 5.

Fig. 4 is an exemplary flowchart 40 of further processes in a method of managing vehicle-based electronic tags according to an embodiment of the present disclosure. The steps of flowchart 40 are described in detail below with reference to fig. 5 and application scenario 10 in fig. 1 as an example.

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

In some embodiments, in location identification, the location of the electronic tag 1200 on the production line 1310 is identified based on the detection of the electronic tag 1200 by a location sensor (not shown) in the production line 1310. The position sensor in the production line 1310 may be the detection device itself in the production line 1310 as described above, or may be a component included in the detection device. Hereinafter, description will be given taking as an example a component included in a detection apparatus as a position sensor.

A position sensor is mounted at a higher location in the production line 1310, for example, may be mounted on the ceiling above the production line 1310 for detecting the electronic tag 1200 to identify the location of the electronic tag 1200 (and the vehicle 1100 to which it is attached) on the production line 1310. For example, two or more position sensors may be utilized to detect the electronic tag 1200 in real time such that the position of the electronic tag 1200 can be accurately identified even though it is moving on the production line 1310. After the position sensor detects the electronic tag 1200, the detection device transmits the identified position of the electronic tag 1200 to a database (hereinafter, sometimes simply referred to as "position database") storing the position of the electronic tag, for example. In the location database, for example, the location of the electronic tag 1200 is stored as a location log of the electronic tag 1200 in association with the ID of the electronic tag 1200 and the time at which the location is recognized. Further, in this manner, other electronic tags on the production line 1310 can be identified in location and a location log for each electronic tag can be stored in a location database.

Note that, since the position sensor is usually installed at an assembly position where the assembly equipment is located, herein, unless otherwise specified, the position of the electronic tag on the production line corresponds to the assembly position where the assembly equipment is installed.

In some embodiments, a visual map is generated about one or more vehicles being produced in the production line 1310 based on the location of the identified one or more electronic tags on the production line 1310. The generation process of the visual map is described by taking the vehicle 1100 and the electronic tag 1200 as examples. For example, when it is desired to generate a visual map of a certain time (e.g., the current time or a certain time in the past), the location log of the electronic tag 1200 may be read from the location database to obtain the location of the electronic tag 1200 at the time as the location of the vehicle 1100 at the time. Additionally, information about the vehicle 1100 in a production order for the vehicle 1100 associated with the electronic tag 1200 may be read from an order database (e.g., based on the ID of the electronic tag 1200) and a visualization model of the vehicle 1100 may be generated based on the information (or looked up in a database storing visualization models of vehicles). The visualization model of the vehicle 1100 may be a two-dimensional or three-dimensional visualization model having an appearance and parameters corresponding to the vehicle 1100. The visual model of the vehicle 1100 is then displayed on a pre-generated map of the production line 1310. In this manner, a visual model of each vehicle being produced in the production line 1310 may be displayed on the map of the production line 1310, thereby generating a visual map of one or more vehicles being produced in the production line 1310. The visual map is not limited to a static map, but may be a dynamic map that dynamically changes according to the real-time location of one or more vehicles. The visual map enables the production progress of vehicles being produced on a production line to be intuitively grasped, and the production of the vehicles is conveniently monitored and managed.

A specific example of the visual map is shown in fig. 5. Fig. 5 is an exemplary visual map 50 regarding one or more vehicles being produced in a production line according to an embodiment of the present disclosure. In the visualization map 50, a map 5100 of a production line (e.g., a portion of the production line 1310) and a visualization model 5200 of a plurality of vehicles are included. It can be seen that the visualization model 5200 of the vehicle in fig. 5 has the same appearance as the corresponding vehicle. Alternatively, when the visualization model 5200 of a certain vehicle in the selected visualization map 50 is selected, various parameters, production states, affiliated departments, and the like of the vehicle may be displayed accordingly.

Returning to the description of fig. 4. In step S4200, abnormality data relating to an abnormal condition of the production line 1310 is recorded, and the abnormality data is associated with the position of the electronic tag 1200 on the production line 1310 at the time of occurrence of the abnormal condition of the production line 1310 to perform processing relating to the abnormality recording. This process will be described in detail below.

As previously described, for example, when the electronic tag 1200 is detected by the detection device in the production line 1310, the assembling device at the corresponding position can be activated to start the action. Specifically, for example, when the electronic tag 1200 reaches a certain mounting position, a detection device at the position detects the electronic tag 1200 and reads its ID. According to the ID of the electronic tag 1200, the inspection apparatus reads a production order of the vehicle 1100 associated with the electronic tag 1200 from the order database, acquires a component of the vehicle 1100 to be assembled at the location from the production order, and then sends an instruction to the assembling apparatus at the location to activate the assembling apparatus to assemble the component to the vehicle 1100. By producing the vehicle 1100 in this manner, the degree of automation of production can be improved, and the production process can be managed easily. However, if the electronic tag 1200 is damaged or lost, or the assembly device in the production line 1310 fails, or the electronic tag 1200 is not detected by the detection device in the production line 1310 (due to being blocked, etc.), the assembly device cannot be properly activated, resulting in an abnormal condition in the production line 1310.

In some embodiments, the abnormal condition of the production line 1310 includes an error in the production line 1310 and a halt in the production line 1310. An error in the production line 1310 refers to, for example, an inability of the assembly equipment in the production line 1310 to operate properly because it was not properly activated. For example, the assembling apparatus may assemble an erroneous component due to its own failure or the assembling accuracy may not be satisfactory. Alternatively, the assembly device may make an erroneous assembly action, for example, due to the detection device sending an erroneous instruction due to the electronic tag 1200 being damaged. The line 1310 being out of service, for example, means that the assembly equipment in the line 1310 is not activated, resulting in the entire line 1310 being stopped for a period of time. For example, when the electronic tag 1200 is lost or undetected by the detection device due to occlusion or the like, the assembling device at the corresponding position cannot be activated, so that the assembling at the position cannot be performed, and all the assembling devices in the entire production line 1310 are forcibly suspended from action, for example, in order to prevent different assembling processes of the same vehicle or production of different vehicles from being confused. Such an abnormal condition of the production line 1310 may last only a few seconds or less, but may also cause a loss.

In some embodiments, the anomaly data for the production line 1310 is obtained from the production line 1310 when an anomaly condition occurs in the production line 1310. When the above-described abnormal condition occurs in the production line 1310, the mounting equipment and/or the inspection equipment at the position causing the abnormal condition may generate abnormal data. The abnormal data includes, for example, an abnormal-condition occurrence time, a fault code, an abnormal-condition duration, and the like. For example, when an abnormal condition occurs due to a failure of the mounting apparatus, abnormal data corresponding to the abnormal condition is generated in the mounting log of the mounting apparatus. Alternatively, for example, when the electronic tag 1200 is damaged or lost or the electronic tag 1200 is blocked by the detection device and the electronic tag 1200 cannot be detected, abnormal data corresponding to an abnormal situation may be generated in the detection log of the detection device. Thus, when an abnormal condition occurs in the production line 1310, abnormal data regarding the abnormal condition of the production line 1310 may be acquired from the assembly equipment and/or the detection equipment in the production line 1310.

The acquired abnormal data related to the abnormal condition of the production line 1310 may be recorded, for example, in a database storing the abnormal data, and the abnormal data may be associated with the location of the electronic tag 1200 at the time of the abnormal condition of the production line 1310 for further analysis of the cause of the abnormality, statistics of the abnormal data, maintenance of the production line, optimization of production management, and the like. The location of the electronic tag 1200 at the time of the abnormal condition of the production line 1310 may be obtained from the location database as described above at the time of the abnormal condition.

In some embodiments, anomaly data for the production line 1310 may be counted and analyzed for one or more locations of the electronic tags 1200 on the production line 1310. Since the location of the electronic tag 1200 on the production line 1310 corresponds to a mounting location, the anomaly data of an abnormal condition occurring at the location can be counted and analyzed for one or more mounting locations for further anomaly cause analysis, production line maintenance, production management optimization, etc. For example, the number of times that an abnormal situation occurs at the location within a predetermined period of time (e.g., one day, one week, one month, or the like), the ratio of the number of times that an abnormal situation occurs at the location to the number of times that all abnormal situations occur, the cause of an abnormal situation occurring at the location and the number or frequency of occurrences of each abnormal situation, the cumulative time that an abnormal situation occurs, the number of times that an abnormal situation occurs per the number of production units, or the like may be counted for one or more assembly locations. In addition, corresponding statistical data at different positions can be compared to find assembly positions with more abnormal conditions, so that weak links in the production process can be analyzed.

In some embodiments, based on the anomaly data of the production line 1310, it may be determined whether the electronic tag 1200 is lost or damaged. As described above, the exception data may include a fault code, an exception condition duration, and the like. Depending on the source of the anomaly data (whether from the detection equipment or the assembly equipment), the fault code in the anomaly data, and the duration of the anomaly, it can be analyzed whether the anomaly condition occurred due to a loss or damage to the electronic tag 1200. For example, when 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 electronic tag 1200 not being detected, and the source of the abnormal data is the detection device, it may be determined that the abnormal condition is caused by the electronic tag 1200 being lost. Alternatively, for example, when the duration of the abnormal condition in the abnormal data exceeds a predetermined time threshold, the fault code indicates that the abnormal condition is due to the detection of the electronic tag 1200 but an error occurs in the detection, and the source of the abnormal data is the detection apparatus and the mounting apparatus, it may be determined that the abnormal condition is caused by the damage of the electronic tag 1200. Of course, these are merely examples, and whether the electronic tag 1200 is lost or damaged may also be determined according to other information in the abnormal data. After determining that the electronic tag 1200 is lost or damaged, an alarm may be issued to the relevant person to inform the relevant person of timely handling. Determining whether the electronic tag 1200 is lost or damaged in this way enables appropriate measures to be taken in time after the electronic tag 1200 is lost, thereby avoiding or reducing the loss caused by the loss or damage of the electronic tag 1200.

In some embodiments, based on the anomaly data of the production line 1310, the placement of position sensors in the production line 1310 may be adjusted and/or production equipment in the production line 1310 maintained. The production equipment in the production line 1310 includes, for example, the assembly equipment and the detection equipment as described above. For example, in a case where it is found that the frequency of occurrence of an abnormal condition at a certain mounting position due to the electronic tag being blocked is high (for example, twice the frequency of occurrence of such an abnormal condition at other positions) by analyzing abnormal data counted for the position, it can be considered that the electronic tag 1200 is blocked due to improper arrangement of the position sensor at the position, so that the arrangement of the position sensor at the position can be adjusted. Alternatively, for example, in a case where it is found by analyzing the abnormal data counted for a certain mounting location that the duration of an abnormal condition caused by the occurrence of a failure of the mounting apparatus at the location is long (e.g., higher than the average of such abnormal condition durations), it may be considered that the mounting apparatus at the location needs to be serviced, so that the mounting apparatus at the location may be maintained. Adjusting the placement of position sensors in the line 1310 and/or maintaining production equipment in the line 1310 in this manner, factors in the line 1310 that are not conducive to production can be discovered and processed in a timely manner, thereby avoiding or reducing losses due to abnormal conditions in the line and improving production efficiency.

Note that the specific contents of the processing relating to the position recognition and the exception recording described above are merely examples, and the execution order of the respective steps is not necessarily limited to the order described above as long as it conforms to a logical order. The position of the electronic tag identified by the processing and the recorded abnormal data can be used in a different usage from the above-described usage.
