Multiple electronic ink screens are respectively arranged at preset workstations of multiple assembly carts; a scanning gun is used to obtain a cart barcode of the assembly cart and assembly data of the electronic ink screen; a device PLC is used to control the operation of the assembly cart, and the device PLC is used to control the operation of the scanning gun; the electronic ink screen manager binds the assembly cart and the electronic black water screen through the cart barcode and the electronic ink screen address, the electronic ink screen manager obtains the status of the assembly cart through the device PLC communication connection, the electronic ink screen manager is communicated with the electronic ink screen, the electronic ink screen manager obtains the status of the electronic ink screen, when the assembly cart is in place and the electronic ink screen operates normally, the electronic ink screen manager controls the electronic ink screen to display the assembly data of its corresponding assembly cart, the electronic ink screen manager obtains the cart barcode and the assembly data of the electronic ink screen through the scanning gun, and evaluates the assembly data of the electronic ink screen based on the cart barcode and the assembly data, and outputs assembly data error information when the assembly data of the electronic ink screen does not match the data sent by the electronic ink screen manager; the operation panel is communicated with the electronic ink screen manager, the operation panel is used to display the operation status of the electronic ink screen manager, and the operation panel is used to display assembly data error information.

[0018] Specifically, the vehicle assembly line includes multiple assembly carts, and the multiple electronic ink screens correspond to the multiple assembly carts one by one, and the multiple electronic ink screens are respectively arranged at the workstations of the corresponding assembly carts. The assembly data is displayed on the electronic ink screen to prompt the user the assembly information of the assembly cart corresponding to the workstation.

[0019] Each assembly cart is provided with a number strip, which includes a cart barcode, which is used to uniquely identify the assembly cart. The scanner obtains the cart barcode by scanning the number strip of the assembly cart. The scanner obtains the assembly data displayed on the electronic ink screen by scanning the display page of the electronic ink screen.

[0020] The equipment PLC is connected to the assembly cart and is used to control the opening, moving, offline and closing of the assembly cart. The equipment PLC is also used to obtain the status of the assembly cart in real time. The equipment PLC is also used to control the start, scanning and closing of the scanner.

[0021] Each of the multiple electronic ink screens corresponds to an electronic ink screen address, and the electronic ink screen address is used to uniquely calibrate the electronic ink screen address. The electronic ink screen manager matches the assembly cart and the electronic ink screen by binding the cart barcode and the electronic ink screen address. The electronic ink screen manager obtains the in-place signal of the assembly cart through the device PLC, and determines the in-place status of the assembly cart based on the in-place signal of the assembly cart. When the assembly cart runs to the specified position, if the electronic ink screen is judged to be running normally according to the electronic ink screen status, the electronic ink screen write data condition is met, and the electronic ink screen manager distributes the vehicle FIS instruction assembly order data to the electronic ink screen by wireless communication.

[0022] In order to ensure the accuracy of the updated data of the electronic ink screen, the assembly data displayed on the electronic ink screen is scanned by a scanner to verify the assembly data on the electronic ink screen. If the verification fails, an alarm is given through the operation panel; if the verification succeeds, the vehicle is automatically released. In some embodiments, if the electronic ink screen fails to update data during the data update process, the electronic ink screen manager will automatically resend the data.

[0023] In some embodiments, the operation panel is used to receive adjustment information input by the user, and the electronic ink screen manager adjusts the assembly data output by the electronic ink screen based on the adjustment information.

[0024] Specifically, the operation panel is also used to receive instructions or information input by the user to respond to emergencies on the production line. The operation panel connects to the electronic ink screen manager based on the received user instructions or adjustment information, and outputs the user instructions or adjustment information to the electronic ink screen manager, so that the electronic ink screen manager adjusts the assembly data based on the adjustment information or user instructions to respond to emergencies on the production line.

[0025] In some embodiments, the adjustment information includes a faulty cart barcode, and the electronic ink screen manager updates the display data of the electronic ink screen in response to the received faulty cart barcode.

[0026] Specifically, the assembly data of the electronic ink screen corresponding to the current assembly cart has been written, but due to external reasons, the assembly cart cannot be assembled. At this time, the electronic ink screen data needs to be reordered. By using a scanner to scan the barcode on the assembly cart, the electronic ink screen manager takes the scanned assembly cart as the starting point, reorders all the electronic ink screen assembly data after this assembly cart, and updates the assembly data of the electronic ink screen.

[0027] In some embodiments, the adjustment information includes inputting a cart barcode corresponding to the faulty electronic ink screen and a replacement electronic ink screen address, and the electronic ink screen manager binds the assembly cart and the replacement electronic ink screen in response to the received cart barcode and replacement electronic ink screen address.

[0028] Specifically, the assembly data of the current assembly cart's electronic ink screen has been written, but due to external reasons, the electronic ink screen is damaged and can no longer display. After preparing a new electronic ink screen, on the operation panel, by entering the cart barcode of the assembly cart with the damaged electronic ink screen and the address of the prepared replacement electronic ink screen, the electronic ink screen manager will automatically update the assembly data on the damaged electronic ink screen to the new replacement electronic ink screen.

[0029] In some embodiments, the adjustment information includes an interruption mark, which is used to mark the assembly data, and the electronic ink screen manager identifies the assembly data based on the interruption mark.

[0030] Specifically, the data of the current assembled car's electronic ink screen has been written, but due to external reasons, the vehicle's parts have not been assembled, so it needs to be temporarily offline and will be online again to continue assembly. At this time, since the data record already exists in the system, the data cannot be updated to the electronic ink screen again because the system has added a duplicate data writing verification function to prevent data from being written repeatedly. At this time, the duplicate data can be updated to the electronic ink screen by marking on the operation panel.

[0031] In some embodiments, the adjustment information includes a cart barcode of the faulty assembly cart, and the electronic ink screen manager interrupts the assembly data of the corresponding electronic ink screen in response to the received cart barcode.

[0032] Specifically, if the current assembly cart cannot be assembled due to a malfunction of the assembly cart or other reasons, the cart barcode can be input on the operation panel to allow the electronic ink screen of the cart to be released directly without writing assembly data.

[0033] In some embodiments, a dry run instruction is input through the operation panel, and the electronic ink screen manager terminates outputting assembly data in response to the dry run instruction.

[0034] Specifically, in cases involving holidays and other situations, the on-site assembly carts need to run empty. On the operation panel, the empty run instruction can be input by selecting the "empty run" mode and clicking the operation to achieve that the electronic ink screens of all assembly carts do not write assembly data.

[0035] In some embodiments, the scanning gun includes a first scanning gun and a second scanning gun, the first scanning gun is used to scan the assembly cart to obtain the cart barcode, and the second scanning gun is used to scan the electronic ink screen to obtain assembly data.

[0036] Specifically, the device PLC is connected to the first scanner and the second scanner respectively for communication, and controls the operation of the first scanner and the second scanner to obtain the barcode and assembly data of the trolley.

[0037] In some embodiments, a first server and a second server are also included, and the operation panel controls the first server and the second server to selectively communicate with the electronic ink screen manager in response to the received switching instruction.

[0038] Specifically, in order to ensure the stable operation of the electronic ink screen manager, a dual-machine hot standby disaster recovery solution is adopted. If one server goes down, the server can be switched by pressing a button on the operation panel, and all data will not be lost.

[0039] The embodiments of the present disclosure have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
