Description

Technical Field

[0001] The utility model relates to the technical field of adapter plates, in particular to a data transfer device. Background Art

[0002] The USB flash drives currently used in the market can only be read and written by one device. If multiple devices need to read and write, the USB flash drives need to be plugged in and out between different devices. During the motherboard test, the speed of serial communication is about 84KB grayscale and 109KB colorscale in 1920*1080 JPG format; the baud rate is 115200, and the theoretical transmission time is about 7~9 seconds, which will seriously increase the overall test time. Develop a data transfer station, connect the USB flash drive to the USB flash drive interface of the data transfer station, and use a USB cable to connect the USB interface of the TV motherboard and the USB port of the PC. The PC sends a command to switch the USB path.

[0003] In the existing technology, during the motherboard test, if a large file (such as a picture file) interacts with the PC, the serial port communication rate affects the transmission time and data loss. The USB flash drive cannot be read and written by multiple devices, and automated testing cannot be achieved. Summary of the invention
