Problems solved by technology
However, some terminal devices do not have a touch screen and number keys, so they cannot directly set the room number and IP address. It is necessary to upload configuration files to each terminal through the network. The operation is cumbersome and there are hidden dangers in network security.
[0003] Originally, setting up the intercom terminal requires the terminal to run the FTP file transfer protocol, allowing the upload of configuration files to the terminal, which will bring hidden dangers to network security and increase the risk of network attacks
At the same time, the operation is more troublesome. It is necessary to carry a laptop to the terminal installation site and connect to the terminal with a network cable.

Description
technical field [0001] The invention relates to a network distribution device and a network distribution method, in particular to an acoustic wave distribution network device and a network distribution method based on sub-ultrasonic communication. Background technique [0002] In the digital building intercom system, each terminal needs to set its own room number and IP address before it can communicate with other terminals through the network. However, some terminal devices do not have a touch screen and number keys, and cannot directly set the room number and IP address. It is necessary to upload configuration files to each terminal through the network, which is cumbersome to operate and poses potential network security risks. [0003] Originally, to set up an intercom terminal, the terminal needs to run the FTP file transfer protocol to allow uploading configuration files to the terminal, which will bring hidden dangers to network security and increase the risk of network...
