Method and system for positioning the secondary loop digital substation remote communication signal

The present invention discloses a method and system for positioning the secondary circuit substation remote communication of a digital signal, the method comprising the steps of: Find the secondary circuit to be confirmed in the remote signaling means signal the spacer layer model; virtual terminal according to the association lookup table remote signaling signal is sent from the remote communication signal corresponding to the secondary circuit of the intelligent terminal to be confirmed; description field remote communication signal sent by the parsing of the intelligent terminal, reading the remote signaling point signal corresponding to the terminal number and hardwired determining secondary circuit; the description field contains the name of the original signal and a remote signal corresponding to the number of hard contact terminal. By analyzing the description field of the present invention, remote communication signal, to obtain the corresponding hard contact terminal information, to determine the secondary circuit, the secondary circuit provides a visual means for the lookup operation and maintenance personnel without extensive inspection work complicated drawings, increase work productivity.
