Application of Signal Fusion Technology in Alarming System for Coal Mine

The signal transmission technology of multi-channel sensor and its implementation method which has characteristics such as good compatibility,wide universality and low cost were studied in the(paper.) The signals of multi-channel sensor at measuring spot were processed and translated by signal(encoding) technology to fuse into a baseband signal and then the signal was transmitted directly or in(frequency)-band mode.The technology improved the signal transmission of alarming system for coal mine safety at present.
