Remote supervisory and controlling device
专利汇可以提供Remote supervisory and controlling device专利检索，专利查询，专利分析的服务。并且PURPOSE:To transfer control information at a high speed by using optical star couplers as passive elements, which correspond to control center devices in n:n, to connect optically plural posts to be controlled and control centers and using dual controllers as a current controller and a stand-by controller. CONSTITUTION:Up data DUa-DUn of individual electric apparatus in posts 1a- 1n to be controlled are taken into remote supervisory and controlling devices 2a-2n and pass transmission controllers 3a-3n and transmission lines 4a-4n consisting of optical fibers and pass an optical coupler of a control center 5 and are inputted to computer systems 9a and 9b for centralized control through dual transmission controllers 8a and 8b used as the current controller and the stand- by controller and similar remote supervisory and controlling devices 7a and 7b. In this case, for example, up data DUa of the post 1a to be controlled is not only inputted to controllers 8a and 8b by the coupler 6 but also transmitted as down data to the other control centers 1b-1n without transfer processings of controllers 8a and 8b in the control center 5. Noise due to a lighting surge, accidents of power systems, etc. is not superposed to transmission lines because optical fibers are used as them, and extension, improvement, etc. are performed without stopping the system because control centers are made dual.，下面是Remote supervisory and controlling device专利的具体信息内容。
