Bobsleigh and Luge Track of the Nagano Winter Olympic Games which will be held in February 1998 is the 14<SUP>th</SUP> one in the world as a system of chilling and icing the entire track with refrigerators. The Nagano's system is the first one in the world as a system of indirectly chilling the track by using brine which is ethylene glycol. The system of the other tracks is a system of directly chilling by expanding ammonia. Mitsubishi Heavy Industries, LTD (MHI) has designed and constructed an ideal ice making system which had refrigerators, pumps, a cooling piping, an automatic control system, and MHI original Distributed Control System (DCS) by thermal dynamic simulation of the track. Optical communication was applied to the DCS in order to connect to thirteen control stations, which were located along the track 1.7km in length. Applying optical communication to the DCS, MHI realized the reliable DCS with anti-electromagnetic interference against, for example Lightning.
