사고현장과 사령실간 화상전송기술에 관한 연구(Ⅱ)

초록

An emergency recovery of accident site shall be fulfilled before everything. Construction of image transmission system is needed to know accident field fast and exact and support recovery. Thus, this paper is studied the method transmitting moving picture of accident site to central center at real time by optical cable which will be the main current of further communication line according to high speed optical communication network plan, following image transmission method in copper cable section of main line in train communication. With monitor image operating usually in Tokyo zone of JR east Japan and the basic structure of accident image transmission network operating in emergency situation, wire/wireless multiple transmission method using codec equipment in the domestic area are tested and analyzed in the paper."
