Communication protocol detection system and method

Abstract

A communication protocol detection system includes an active detection terminal and a passive detection terminal. The active detection terminal includes a first communication interface, a command sending module, and a response receiving module. The passive detection terminal includes a second communication interface, a command receiving module, and a response sending module. The command sending module is for sending a plurality of detection commands in sequence to the passive detection terminal via the first communication interface. The command receiving module is for receiving detection commands in sequence via the second communication interface, and sending detection commands to the response sending module. The response sending module is for determining whether a currently received detection command can be identified. If the currently received detection command can be identified, the response sending module sends a response to the active detection terminal to make the command sending module stop sending detection commands.
