Description

Background Art

[0002] In modern car factories, electric monorail system (EMS) conveying system is mostly used to lift and transport vehicles or vehicle parts. EMS conveying system mainly includes multiple lifting devices (also called self-propelled trolleys, such as heavy-duty EMS or EMS) and programmable logic controllers for controlling the lifting devices.

[0003] During the vehicle assembly process, the spreader in the conveyor system may be shut down by the programmable logic controller or due to a sudden power outage during operation, resulting in the loss of vehicle information installed on the spreader.

[0004] According to the related art, after the spreader is accidentally shut down or suddenly loses power, the vehicle information installed on the spreader needs to be manually input into the programmable logic controller before normal operation can be performed.

[0005] However, manual input is inefficient and can introduce errors. In addition, since the PLC controls multiple spreaders, a large amount of data needs to be entered, resulting in a long input time. This increases spreader downtime and affects production schedules.

[0006] Therefore, there is a need for data backup technology for vehicle assembly. Summary of the invention

[0026] The present invention will be described below with reference to the flowcharts and / or block diagrams of the methods, devices (systems) and computer program products of the embodiments of the present invention. It should be understood that each box in the flowchart and / or block diagram and the combination of boxes in the flowchart and / or block diagram can be implemented by computer program instructions.

[0029] Although each operation is described in conjunction with a specific device, it will be appreciated by those skilled in the art that the operations described above may be performed by devices different from the devices described above, and the present disclosure does not limit this. In addition, although described as different devices, it will be appreciated by those skilled in the art that the above devices may be combined together or further split into several devices, and the present disclosure does not limit this.

[0030] As described above, the embodiments of the present disclosure provide a data backup method and system for vehicle assembly.

[0031] Figure 1 is a flow chart showing a data backup method 100 for a vehicle assembly according to at least one embodiment of the present disclosure.

[0032] like Figure 1 As shown, the method 100 includes, at step S101, acquiring identification information of the spreader and identification information and status information of the vehicle mounted on the spreader.

[0033] For example, the identification information of the spreader and the identification information and status information of the vehicle installed on the spreader (for example, an EMS or a HEMS) can be obtained from a programmable logic controller that controls the spreader. A programmable logic controller can generally control multiple spreaders (for example, 60), but the present disclosure does not limit the specific number. The identification information and status information of the vehicle installed on the spreader can be obtained by the programmable logic controller using S7 signaling, for example.

[0034] In one example, the identification information of the spreader may include, for example, a code of the spreader.

[0035] In one example, the vehicle identification information may include a unique code indicating the model and configuration of the vehicle.

[0036] In practice, the model and configuration of the vehicle usually determines the type and / or parameters of the operation to be performed on the vehicle. Therefore, a unique code can be used for a specific model and configuration of the vehicle, and then a lookup table including the unique code and the type and parameters of the operation to be performed can be established. The type and parameters of the operation to be performed can be determined by a simple lookup operation on the lookup table, thereby making subsequent operations more convenient.

[0037] In one example, in addition to the unique code indicating the vehicle model and configuration, the vehicle identification information may also include the vehicle license plate number and / or vehicle model, etc.

[0038] In one example, the vehicle status information includes one or more of the following: ground wire check, power supply check, distance check, workstation status, locked status, unlocked status, hoisted status, and lowered status.

[0039] The method 100 may further include, at step S103 , establishing a communication path between a programmable logic controller that controls the spreader and a computer associated with the programmable logic controller.

[0040] For example, a communication path between a programmable logic controller and a computer can be established by using a network cable. Alternatively, a communication path between a programmable logic controller and a computer can be established by using components such as a switch. In addition, a wireless communication path can also be established. In one example, the communication path established between a programmable logic controller and a computer can transmit data according to S7 signaling, for example.

[0041] In one example, the method 100 may further include, at step S105 , writing the identification information of the spreader in association with the identification information and status information of the vehicle into a computer associated with the programmable logic controller via the established communication path.

[0042] The writing process may, for example, include receiving identification information of the spreader (e.g., a code of the spreader) and identification information and status information of the vehicle via the established communication path, and then writing the received identification information of the spreader and identification information and status information of the vehicle in association with each other into a computer associated with the programmable logic controller.

[0043] In one example, the identification information of the spreader and the identification information and status information of the vehicle may be stored in a computer memory in a table format, for example, wherein the identification information of each spreader (e.g., spreader number) and the identification information and status information of the vehicle mounted on the spreader are stored as a row of the table.

[0044] By utilizing the method according to an embodiment of the present disclosure, identification information of the spreader and identification information and status information of a vehicle mounted on the spreader are associatedly written into the computer via a communication path between a programmable logic controller that controls the spreader and a computer associated therewith, and the identification information of the spreader and identification information and status information of the vehicle mounted on the spreader can be backed up in the computer for subsequent use (e.g., fault recovery).

[0045] Figure 2 A schematic diagram showing identification information of a spreader and identification information and status information of a vehicle stored in a memory according to one embodiment.

[0046] Figure 21 shows the identification information of the spreader and the identification information and status information of the vehicle stored in the memory of the computer in the form of a table, wherein the coding of the spreader and the identification information and corresponding status information of the vehicle installed on the corresponding spreader are shown.

[0047] exist Figure 2 In the figure, 60 spreaders are shown for illustration purposes, which means that the programmable logic controller can control 60 spreaders. However, those skilled in the art will understand that the present disclosure is not limited to the specific number of spreaders. In fact, the number of spreaders depends on the number of spreaders that the programmable logic controller can control.

[0048] like Figure 2 As shown, the unique code is 5 (indicating its corresponding vehicle model and configuration) and the vehicle number is AAAA, and the vehicle model is AA, which is installed on the sling 1, wherein the ground wire check passed, the power supply check passed, the distance check passed, the locking check failed, and it is in the hoisting state. The unique code is 7 (indicating its corresponding vehicle model and configuration) and the vehicle number is BBBB, and the vehicle model is BB is installed on the sling 2, wherein the ground wire check failed, the power supply check passed, the distance check failed, the locking check failed, and it is in the lowering state. Similarly, the unique code is 10 (indicating its corresponding vehicle model and configuration) and the vehicle number is XXXX, and the vehicle model is XX is installed on the sling 60, wherein the ground wire check failed, the power supply check passed, the distance check passed, the locking check passed, and it is in the lowering state.

[0049] In one example, the method 100 may further include: during the process of writing the identification information of the spreader in association with the identification information and the status information of the vehicle into the programmable logic controller, displaying the process in real time on a display device associated with the computer.

[0050] For example, a display device associated with a computer may be a display device connected to the computer via a wired or wireless connection. Alternatively, a display device associated with a computer may be part of another computer (e.g., a display of another computer). Here, "associated" means that data can be transmitted between the computer and the display device, and then displayed on the display device.

[0051] For example, a graphical user interface may be generated by a computer on a display device to display, for example, identification information of a sling and identification information and status information of a vehicle, and / or instructions for controlling a computer or performing data transmission (e.g., writing and / or reading) may be received via the graphical user interface displayed on the display device.

[0052] Figure 3 A schematic diagram of a vehicle data backup main interface that can be displayed on a display device is shown. Figure 3The “read area” in FIG. 1 shows the process of writing the identification information of the spreader and the vehicle data (eg, including the identification information and status information of the vehicle) into the computer.

[0053] According to this example, by displaying the identification information of the spreader and the process of writing (or reading) the vehicle data to the computer in real time on a display device associated with the computer, the process of writing the identification information of the spreader and the vehicle data to the computer is made more intuitive, thereby ensuring its correct operation.

[0054] This process of writing the identification information of the spreader and the identification information and status information of the vehicle mounted on the spreader to the computer (or the data backup process) can be automatically triggered at predetermined intervals (for example, once a minute) or manually triggered by the user using a graphical user interface displayed on a display device associated with the computer.

[0055] In one example, the method 100 may further include: after writing the identification information of the spreader in association with the identification information and status information of the vehicle into the computer, displaying the identification information and status information of the vehicle on a display device associated with the computer.

[0056] For example, you can activate Figure 3 Click the "Vehicle Data" button in the display to activate the display of the spreader identification information and vehicle data. For example, the interface displayed on the display device may be similar to that in Figure 2 The table format shown in .

[0057] According to this example, after the vehicle data is written to the computer, the written identification information of the sling and the identification information and status information of the vehicle are also displayed on a display device associated with the computer, so that the operator has a more intuitive understanding of the identification information and status of the vehicle installed on the corresponding sling.

[0058] In one example, the method 100 may further include: after the spreader fails, reading from the computer the identification information of the spreader and the identification information and status information of the vehicle that were written into the computer before the spreader fails; and writing the identification information of the spreader to the programmable logic controller in association with the identification information and status information of the vehicle.

[0059] For example, a spreader failure may mean that the spreader is accidentally shut down by the programmable logic controller, or the spreader is shut down due to a sudden power loss, etc.

[0060] This process of transferring the identification information of the spreader and the identification information and status information of the vehicle mounted on the spreader from the computer to the programmable logic controller (or the vehicle data recovery process) can be automatically triggered in response to satisfying a predetermined condition (for example, the spreader is powered on again after a power outage), or can be manually triggered by a user by utilizing a graphical user interface displayed on a display device associated with the computer.

[0061] According to this example, after a spreader failure, the spreader identification information and the vehicle identification information and status information written into the computer before the spreader failure are read from the computer associated with the programmable logic controller and written (or restored) into the programmable logic controller, thereby avoiding manual data input, shortening the fault recovery time and reducing the possibility of errors introduced by manual operation.

[0062] In one example, the method 100 may further include: during the process of writing the identification information of the spreader in association with the identification information and the status information of the vehicle into the programmable logic controller, displaying the process in real time on a display device associated with the computer.

[0063] Figure 3 The "write area" in FIG. 1 shows the process of vehicle data from the computer to the programmable logic controller.

[0064] According to this example, by displaying the identification information of the spreader and the process of vehicle data being read from the computer programmable logic controller and then written to the programmable logic controller in real time on a display device associated with the computer, the process of the spreader identification information and vehicle data being read from the computer and written to the programmable logic controller is made more intuitive, thereby ensuring its correct operation.

[0065] Figure 4 A schematic diagram of a data backup system 400 for vehicle assembly according to an embodiment of the present disclosure is shown. Figure 5 The following is a schematic diagram of the use environment of the data backup system for vehicle assembly. Figure 4 and Figure 5 The data backup system 400 is described.

[0066] like Figure 4 As shown, a data backup system 400 for vehicle assembly may include a programmable logic controller 401 and a computer 403 .

[0067] The programmable logic controller 401 is configured to obtain identification information of the spreader and identification information and status information of the vehicle mounted on the spreader. The computer 403 is associated with the programmable logic controller 401 and is configured to write the identification information of the spreader in association with the identification information and status information of the vehicle into the computer via a communication path established between the programmable logic controller and the computer.

[0068] like Figure 5 As shown, the programmable logic controller 501 can be connected to the spreader 1, the spreader 2 ... and the spreader N to control the spreader 1-spreader N, wherein the number N represents the number of spreaders that the programmable logic controller can control. Figure 5 It is also shown that the programmable logic controller 501 can be connected to the switch.

[0069] like Figure 5 As shown, the computer 503 associated with the programmable logic controller 501 can be connected to the programmable logic controller 501 through a switch (specifically, a port of the switch). However, those skilled in the art will understand that "associated" here requires that a communication path can be established between the programmable logic controller 501 and the computer 503.

[0070] In one example, the vehicle identification information includes a unique code indicating the model and configuration of the vehicle.

[0071] In one example, the computer 403 stores the identification information of the spreader and the identification information and status information of the vehicle in a table in a memory of the computer.

[0072] like Figure 4 As shown, the data backup system 400 for vehicle assembly may also include a backup display device 405. Figure 5 As shown, the display device 505 is connected to the computer 503. However, it will be understood by those skilled in the art that the connection shown here is only an example of "association". "Association" means that data can be transmitted between the computer and the display device, and then can be displayed on the display device.

[0073] In one example, the computer 403 is further configured to display in real time on a display device associated with the computer the process of writing the identification information of the spreader in association with the identification information and status information of the vehicle to the computer associated with the programmable logic controller.

[0074] In one example, the computer 403 is further configured to: after the identification information of the spreader is associated with the identification information and status information of the vehicle and written into the computer, display the identification information and status information of the vehicle on a display device associated with the computer.

[0075] In one example, the computer 403 is further configured to: after the spreader fails, read from the computer the identification information of the spreader and the identification information and status information of the vehicle that were written into the computer before the spreader fails; and write the identification information of the spreader to the programmable logic controller in association with the identification information and status information of the vehicle.

[0076] In one example, the computer 403 is further configured to: during the process of writing the identification information of the spreader in association with the identification information and status information of the vehicle into the programmable logic controller, display the process in real time on a display device associated with the computer.

[0077] For the convenience of description, some contents described about the method 100 are omitted when describing the system 400. However, those skilled in the art will understand that all contents described about the method 100 above are also applicable to the system 400.

[0078] By utilizing the system according to the embodiment of the present disclosure, identification information of the spreader and identification information and status information of the vehicle mounted on the spreader are associatedly written into the computer via a communication path between a programmable logic controller that controls the spreader and a computer associated therewith, and the identification information of the spreader and identification information and status information of the vehicle mounted on the spreader can be backed up in the computer for subsequent use (e.g., fault recovery).
