In order to facilitate the testing, the system’s supervision
terminal will extract a set of data to transmit from Nand
Flash.When testing communication function of the system,
the first PC is connected to the Internet.Then the host
computer is set as TCP server with TCP/UDP debugging
assistant and the network monitoring is opened[8].Data
transfer test can be carried out after a connection is
established between the terminal and the host computer.
The system will send data from Nand Flash by 4G
