Construction of central control subcenter system for disaster preparedness at Osaka Gas Co., Ltd.

摘要

The central control system of Osaka Gas Co., Ltd. serves as the core system controlling the company's production of city gas. From the lessons learned in the Great Hanshin Earthquake, a separate central control subcenter having control functionshas been constructed as a preparedness measure in the event that the Central Safety and Distribution Control Dept. at the company's headquarters is struck by disaster. The central control systems of headquarters and the subcenter continuously monitor each other's operating condition, and provide mutual backup. Such a system is unprecedented in the gas supply industry in Japan.
