[0026] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other.

[0027] The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0028] Figure 1 Schematic diagram of a network cable fault location system for an aging vehicle proposed in an embodiment of the present application. Figure 1 As shown, the system includes: An execution unit, used to load multiple PCs onto the aging vehicle in a fixed order; The management server is used to control the startup of each PC in sequence according to the loading order of the PCs; The diagnostic server is used to sequentially allocate IP addresses to each PC according to the startup sequence of each PC; perform aging test on all PCs on the aging vehicle and record the aging status of each PC; The management server is further used to determine whether there is a network cable fault in the aging vehicle based on the aging status of each PC on the aging vehicle; if there is a network cable fault in the aging vehicle, determine the location of the faulty network cable.

[0029] In this embodiment, the idle aging cart is moved to the chassis offline, and the execution unit controls the motor to perform the PC loading operation. When loading the PC into the aging cart, the execution unit loads the chassis in a fixed order. After the PC is loaded, the aging cart is moved to the aging area for plug-in testing. Each aging area is deployed with at least one point, and each point is deployed with an aging rack, which can hold an aging cart.

[0030] Figure 2 It is a schematic diagram of placing an aging vehicle in an aging area in one embodiment of the present application. Figure 2In the aging car, the aging car is placed in the aging rack. The location of the aging rack is numbered A10. Its shelves have 5 layers and 2 rows for loading PCs, and each row can load two PCs. A switch is deployed on the aging car. The switch is connected to the external diagnostic server through a main network cable. Each PC on the aging car is connected to the branch network cable on the aging car through its own network cable interface. Each branch network cable is uniformly connected to the switch. The power interface of each PC is connected to the aging car through multiple branch power cables on the aging car. The main power cable of the aging car is connected to the external power supply equipment, and provides power for all PCs at the same time.

[0031] Before loading the PCs, a fixed order for loading the PCs is pre-set, and the subsequent control of PC startup and allocation of IP addresses all follow this fixed order. For example, there are currently 10 PCs that need to be loaded onto the aging vehicle. Set the fixed order to "from left to right, each column from bottom to top", and the 10 PCs will be placed in the positions of "1-1, 2-1, 3-1...5-2" in order.

[0032] When the PCs on the aging vehicle are turned on in sequence, the diagnostic server sequentially assigns an IP address to the PCs through the switch on the aging vehicle. In this embodiment, the startup sequence of each PC is made consistent with the loading sequence of the PCs, so as to associate the IP address with the specific location of the PC, and then the diagnostic server can deduce the location of the PC in the aging vehicle according to the IP address.

[0033] For example, the loading order of the three PCs is: first load PC1 at position 1-1, then load PC2 at position 2-1, and then load PC3 at position 3-1. When controlling the startup of the three PCs, the startup order is: PC1 startup, then PC2 startup, and then PC3 startup. The subsequent diagnostic server reads the IP address of PC2 and determines that the order of the IP address is 2. Combined with the fixed order of PC loading "from left to right, each column from bottom to top", it can be determined that the position of PC2 is 2-1, that is, layer number 2 and column number 1.

[0034] In this embodiment, the IP address is associated with the actual location of the PC by keeping the loading order of the PC in the aging car consistent with the startup order of the PC. The diagnostic server transmits the test program to each PC through the switch on the aging car to perform the aging test and records the aging status of each PC. And, based on the aging status of the PC, it is determined whether there is a network cable failure. The aging status of the PC includes: normal state, timeout state or fault state. In the case of a network cable failure, the diagnostic server can accurately locate the main network cable of the aging car or the branch network cable where any PC is located through the IP address of the corresponding PC, so as to quickly locate the faulty network cable, so as to eliminate the fault in time, ensure the normal progress of the aging test, and improve the efficiency of the aging test.

[0035] As an implementation mode of the present application, the diagnostic server is used to perform an aging test on all PCs on the aging vehicle and record the aging status of each PC, including: According to each IP address, determine the layer number and column number of the PC corresponding to the IP address on the aging vehicle; Transmitting a test program to each PC and running it to perform an aging test on each PC; during the aging test, determining the aging status of each PC; the aging status includes: aging time and download network speed; Record the layer number, column number, and corresponding aging status of each PC.

[0036] In one embodiment, after assigning IP addresses to each PC, the diagnostic server derives the layer number and column number of each PC in the aging rack based on the IP address. Since the order in which the PCs are powered on is consistent with the order in which they are loaded, the order of the IP addresses is also consistent with the order in which the PCs are loaded, based on which the diagnostic server can determine the layer number and column number of each PC.

[0037] After the PC is turned on, the diagnostic server transmits the test program to all PCs on the aging vehicle through the main network cable connected to the aging vehicle, and runs it on each PC to complete the aging test. During the aging test, the diagnostic server records the layer number, column number and corresponding aging status of each PC. Specifically, the aging status includes: aging time and download network speed. The aging time refers to the time consumed by the PC to complete the aging test, and the download network speed refers to the network data transmission rate between the PC and the diagnostic server.

[0038] In one embodiment, the diagnostic server generates log data based on the aging test results of all PCs in the aging vehicle and sends it to the management server for storage. The management server stores the log data records, which can be used as product quality assessment data support to facilitate more intuitive monitoring of the aging detection of the production line.

[0039] As an implementation mode of the present application, the management server is further used to determine whether there is a network cable fault in the aging vehicle based on the aging status of each PC on the aging vehicle, including: Compare the download network speed with a network speed threshold; if the download network speed is lower than the network speed threshold, determine that there is a network cable fault in the aging vehicle; Or, the aging time is compared with an aging threshold; when the aging time is greater than the aging threshold, it is determined that the aging vehicle storage network cable is faulty.

[0040] In one embodiment, based on any data of the aging status, it is determined whether the aging vehicle has a network cable fault. When the PC completes the aging test, the management server obtains and reads the aging status of the PC from the diagnostic server, including the aging time and download network speed of the PC. It is determined whether the aging vehicle has a network cable fault by any one of the aging time and the download network speed. Specifically, the aging time is compared with the aging threshold. If the aging time is greater than the aging threshold, it means that the data transmission delay between the PC and the diagnostic server is large, and there may be a problem of speed reduction. In this case, it is determined that the aging vehicle has a network cable fault. The download network speed is compared with the network speed threshold. When the download network speed is lower than the network speed threshold, it means that there may be a network fault between the PC and the diagnostic server. In this case, it is determined that the aging vehicle has a network cable fault. In actual applications, the aging threshold and the network speed threshold can be set according to the network environment in the actual application scenario.

[0041] In this embodiment, by determining whether there is a network cable fault based on the aging time or the download network speed, all faulty network cables can be effectively detected, thereby improving the efficiency of the aging test.

[0042] In one embodiment, considering that the aging time and the download speed may be affected by the network environment or the load of the diagnostic server, the aging state reaches the corresponding threshold, which is not caused by a network cable failure. Therefore, in this embodiment, buffer values ​​are set based on the aging threshold and the network speed threshold. Specifically, a first buffer value is set based on the aging threshold. When the aging time of the PC is greater than the aging threshold, but the difference between the two is not greater than the first buffer value, it is determined to be normal. A second buffer value is set based on the network speed threshold. When the download speed is lower than the network speed threshold, but the difference between the two is not greater than the second buffer value, it is determined to be normal.

[0043] By setting the first buffer value and the second buffer value, the influence of factors such as the network environment and the load of the diagnostic server can be avoided to prevent misjudgment of the network cable fault of the aging vehicle, thereby improving the accuracy of locating the network cable fault.

[0044] As an implementation manner of the present application, the management server is further used to determine the location of the faulty network cable when there is a network cable fault in the aging vehicle, including: Obtaining the aging status of all PCs on the aging vehicle from the diagnostic server; When the download speed of all PCs is lower than the speed threshold, or when the aging time of all PCs is greater than the aging threshold, it is determined that the main network cable of the aging vehicle is faulty. Determine the location of the faulty network cable based on the main network cable of the aging vehicle; When the download network speed of at least one PC is not lower than the network speed threshold, or the aging time of at least one PC is not greater than the aging threshold, it is determined that the branch network cable of the aging vehicle is faulty; Locate the faulty branch network cable, including: Determine a PC whose download speed is lower than the speed threshold or whose aging value is greater than the aging threshold as a target PC; The location of the faulty network cable is determined based on the layer number and column number corresponding to the target PC.

[0045] In one embodiment, when the aging vehicle has a network fault, it is necessary to further locate the faulty network cable. The management server obtains the aging status of all PCs on the aging vehicle from the diagnostic server, including the aging time, download network speed, and the layer number and column number of the PC.

[0046] The aging status of all PCs is judged to determine whether the aging status of all PCs on the aging vehicle meets the threshold. If all PCs fail, it is determined that the main network cable of the aging vehicle is faulty. Further, the location where the main network cable of the aging vehicle is laid is determined as the location of the faulty network cable.

[0047] If only some of the PCs in the aging vehicle are faulty and some are normal, it means that some of the branch network cables in the aging vehicle are faulty. Further, the locations of multiple faulty network cables are determined based on the layer number and column number of each faulty PC.

[0048] As an implementation mode of the present application, the aging vehicle network cable fault location system further includes a code scanning device; The management server is further used to control the code scanning device to sequentially scan and record the serial numbers of all PCs before the execution unit loads at least one PC onto the idle aging vehicle; The management server is further used to associate the serial number of each PC with the layer number and column number on the aging vehicle based on the fixed sequence.

[0049] In one embodiment, before the execution unit loads the PC onto the aging machine, the management server controls the code scanning device to scan and store the SN (Serial Number) of the PC to be tested for aging, so as to locate the PC after a failure occurs during subsequent testing. After the PC is loaded onto the aging vehicle, the management server associates the point number of the aging area, the shelf number of the aging vehicle, and the SN number of the PC. In addition, after the PC is loaded onto the aging vehicle, the management server also determines the layer number and column number of each PC in the aging vehicle based on the order of the scanned SN numbers of the PCs, the fixed order of reprinting, and the capacity of the aging vehicle. The point number of the aging area, the shelf number of the aging vehicle, the layer number, the column number, and the serial number of the PC are associated and stored.

[0050] As an implementation mode of the present application, the management server is further used to obtain the serial number of the target PC according to the layer number and column number corresponding to the target PC; In the case where the main network line fails, first fault information is generated based on the shelf number of the aging vehicle and the point number of the aging area; In the case that a branch network cable fails, second fault information is generated based on the shelf number of the aging vehicle, the point number of the aging area, the serial number, the layer number and the column number of the target PC.

[0051] In one embodiment, the management server generates fault information according to different network cable faults. If the network cable fault is a main network cable fault, the first fault information is generated based on the point number of the aging area and the shelf number of the aging vehicle.

[0052] In the case of branch network cable failure, it is necessary to determine the location of the branch network cable to which each faulty PC is connected. The management server obtains the layer number and column number corresponding to the aging state with the fault from the diagnostic server, and determines the SN number of the corresponding faulty PC according to the layer number and column number. Further, based on the location information of each faulty PC (including the aging area point number, shelf number, layer number, column number, and serial number), the second fault information is generated.

[0053] As an implementation mode of the present application, the aging vehicle network cable fault location system further includes a user interface; The management server is further configured to generate first prompt information based on the first fault information and display the first prompt information on the user interface; the first prompt information is configured to prompt the user to repair the main network cable; Or, generate a second prompt message based on the second fault information and display it on the user interface; the second prompt message is used to prompt the user to repair the branch network cable.

[0054] In one embodiment, the system further includes a user interface. After the management server generates the first fault information or the second fault information, a prompt message is generated based on the fault information and displayed on the user interface. By generating the first prompt message or the second prompt message, the user is reminded of the specific location where the network cable needs to be replaced. For a main network cable failure, the location can be accurately determined to be an aging vehicle, and for a branch network cable failure, the location can be accurately determined to be a branch network cable connected to a single PC. By displaying the first prompt message or the second prompt message in the user interface, the user can replace the network cable in time to troubleshoot the problem and avoid slowing down the production progress.

[0055] In one embodiment, the management server obtains the aging status of each PC on the aging vehicle from the diagnostic server. The serial number of the PC is obtained by searching the layer number and the column number. However, it is not intuitive enough to locate the branch network cable connected to the PC using the layer number and the column number. Therefore, in this embodiment, in order to enable the management server to more intuitively obtain the network cable fault status of the aging vehicle, the diagnostic server generates a temporary number for each PC based on the point number of the aging area where the aging vehicle is located, and associates and stores the temporary number of each PC with the aging status. Furthermore, when the management server obtains the aging status of each PC from the diagnostic server, it reads the temporary number at the same time, and generates the second fault information and the second prompt information based on the temporary number, so that the user can more intuitively and quickly determine the location of the faulty network cable.

[0056] like Figure 2 As shown, the location of the aging rack is numbered A10, and the temporary number of the PC at the 1st floor and 1st column on the aging vehicle is "A10-01". If the branch network cable connected to the PC fails, the management server generates the second prompt information by obtaining the temporary number "A10-01" from the diagnostic server, so that the user can intuitively and quickly determine the specific location of the faulty network cable.

[0057] As an implementation mode of the present application, the aging vehicle network cable fault location system further includes at least one automatic guided vehicle; The automatic guided vehicle is used to move the idle aging vehicle to the chassis offline, and send the shelf number of the aging vehicle to the management server, so that the management server controls the execution unit to load the PC onto the aging vehicle; And, it is used to move at least one loaded aging vehicle to the aging area, and send the point number of the aging area to the management server, so that the management server controls the diagnostic server to perform aging tests on all PCs in the aging area.

[0058] In one embodiment, the system further includes at least one AGV (Automated Guided Vehicle) for transporting the aging vehicle.

[0059] In one embodiment, a MES (Manufacturing Execution System) is deployed in the management server, the execution unit is based on a PLC (Programmable Logic Controller), a DIAG (Diagnostics) program is deployed in the diagnostic server, and the management server controls multiple automatic guided vehicles to move the aging vehicles.

[0060] In this embodiment, the process of locating the fault of the network cable of the aging vehicle is as follows: (1) The automated guided vehicle moves the idle shelf of the aging vehicle to the chassis offline location, and then sends the shelf number of the aging vehicle to the management server (where the MES system is deployed); (2) The management server stores the shelf number and then notifies the execution unit (PLC system) to transmit it to the PC; (3) The execution unit moves the chassis to the code scanning device through the conveyor and notifies the management server; (4) The management server controls the barcode scanning device to scan the barcode, read the serial number (Serial Number) on the PC chassis to be loaded on the aging vehicle, and store it. After the label production order number and SN number are scanned, the execution unit is notified to load the PC chassis onto the aging vehicle in a fixed order.

[0061] (5) When an aging cart is full, the PLC system notifies the management server that the shelf is full; (6) The management server controls the AGV to move the aging vehicle to the aging area. The AGV sends the aging area number to the management server.

[0062] (7) The management server derives the layer number and column number of each PC based on the capacity of the aging cart and the fixed order of loading PCs. The aging area number, the shelf number of the aging cart, the layer number and column number of each PC, and the serial number are associated and integrated and stored; (8) The management server sends the aging area number and the shelf number of the aging vehicle to the diagnostic server, and then controls each chassis to start up in a fixed order; (9) The diagnostic server assigns IP addresses in sequence according to the boot order, and derives the shelf layer number and column number, and records the aging status of the PC based on the layer number and column number. The management server obtains the aging time and download speed detected by the diagnostic server, and compares them with the set threshold to determine whether there is a network cable failure.

[0063] In the case of a faulty network cable, the management server searches for the corresponding PC serial number from the stored association information based on the aging area number, shelf number, layer number, and column number of the aging vehicle sent by the diagnostic server, thereby determining the specific PC.
