[0050] Get the serial number of the corresponding module, display it on the corresponding module interface, and determine whether the serial number is normal. If not, re-get the serial number of the corresponding module. If normal, generate a file named with the serial number, and determine whether there is a file with this file name locally. If so, load it to the fusion device to complete the loading of parameters. If not, read the rear parameter file from the serial port to determine whether the read file is normal. If not, read the rear parameter file from the serial port again. If normal, decompress the file and load it to the fusion device to complete the loading of parameters.

If normal, generate a file named with the serial number, and determine whether the file is empty. If it is empty, save it locally. If not, save the fusion device configuration parameters and save it locally.

[0052] Get the serial number of the corresponding module and generate a file named with it. The judgment process is the same as saving to the local computer. Determine whether the file to be saved exists locally. If it exists, compress it into 7z format and send it through the serial port. The feedback interface is displayed, and the file is saved to the corresponding projection module. If it does not exist, save it locally first, then compress it into 7z format, send it through the serial port, and the feedback interface is displayed, and the file is saved to the corresponding projection module.
