自治体向け環境放射線監視テレメータシステムの構築

摘要

環境放射線監視テレメータシステムとは，原子力施設周辺の空間放射線量率を24時間365日連続で測定•監視し，環境放射線監視センター，オフサイトセンター，県庁，市役所などの主要防災拠点や，ホームページを介し近隣の住民へ測定データを広く配信するものである。富士電機は，鹿児島県全域の空間放射線量率を測定する環境放射線監視テレメータシステムにおいて，衛星通信によるデータ伝送路の多重化，非常用発電機による電源強化，サーバシステムの多重化を行い，大規模災害発生時も継続して測定を可能とする震災対応型システムを構築した。また，県庁災害対策本部室への大型LCDマルチスクリーン設置やタブレツト端末を用いた屋外での監視業務の実現など，最新のIT枝術も採用したので，これらについて紹介する。%The Remote Radiation Monitoring System in Environment is the system that provides the general public with measurement data of ambient dose at the boundaries of monitoring areas surrounding a nuclear facility. The data measured and monitored continuously for 24 hours a day, 365 days a year is sent to key disaster- prevention facilities such as nuclear environmental monitoring facilities and off-site facilities administered by local municipalities, prefectural office and municipal office. Such dissemination of information enables local residents to obtain those data via websites, etc. Fuji Electric has established the Remote Monitoring System in Environment that measures ambient dose in the entire area of Kagoshima prefecture. By multiplexing of satellite communication data transmission channel, ensuring backup power via emergency generator and multiplexing server system, the system is capable of responding to disasters, measuring continuously even at the time of large-scale disaster. Also, Fuji Electric has applied the latest IT technologies to the system. The following description includes installation of a large multiscreen LCD at disaster countermeasures office in the prefectural office, realization of outdoor monitoring task using a tablet type terminal device, and other technologies used for this system.
