Disclosed is a method and system for self-adaptively transmitting communication signals. The method comprises: a host acquires its own position information and position information of each terminal, and then calculates to acquire a relative position relationship between the host and each terminal according to the acquired position information; and the host matches each communication signal to be transmitted with each terminal according to the relative position relationship between the host and each terminal, and wirelessly transmits corresponding communication signals to each terminal according to the matched correspondence. By means of the technical scheme of the present invention, the complex wiring and wire plugging processes of wired transmission can be omitted, also the self-adapting transmission of signals is achieved, and the working efficiency is improved.
