PURPOSE:To collect a power source control, to complete a control function and to execute the optimum operation control of the power source by giving a command from a command means to a supervising means corresponding to a station to turn on the power source and controlling the feeding of the station. CONSTITUTION:The title system is composed of plural stations 1a to 1f made into a network, in which a signal is inputted and outputted through an optical transmission line 3, a command means 5 to command the on and off of the power source of the stations 1a to 1f, a converting means 7 to convert the command from the command means 5 to a control signal to turn on and off the power source and supervising means 9a to 9f to execute the ON/OFF of the power source of the station. Thus, since the feeding control of the supervising means 9a to 9f can be executed in accordance with the command from the command means 5, the power source of respective stations 1a to 1f can be collectively controlled at one place. Thus, the power source control function of the stations 1a to 1f is improved and the optimum operation control can be executed. |
