Specifically, the upper computer starts the UDP broadcast service after selecting a hotspot connected to a nearby wireless router, and waits for a response from the VCI device. If the VCI device successfully answers, the information of the VCI device is responded to the upper computer, and the information of the VCI device is analyzed by the upper computer. The upper computer analyzes the IP address of the VCI device (the IP address of the WIFI network card of the VCI device), establishes TCP network connection with the VCI device and starts wireless communication diagnosis
And S6, if the VCI device does not respond after overtime and the overtime times are more than the specified number, the upper computer pops up a prompt message for requesting to access the USB cable.
S7, the upper computer continuously inquires the network card name of the pc machine as a preset character, and the IP address range is in a preset range.
If the network card name of the pc is a preset character and the IP address range is within a preset range, such as 192.168.100.150-192.168.100.254, it can be determined that the USB line is accessed.
