PURPOSE:To improve the utility and to realize the security of the installation efficiency by connecting an operation means and a controller via a home bus and interconnecting the controller and a display device with a video transmission line remotely so as to increase an operational location with a simple means. CONSTITUTION:A terminal equipment 2 is connected to a home bus 3 and a prescribed number of operation devices 14 and a central controller 15 are connected to the bus. Moreover, the central controller 15 and an antenna 6 are connected to a video signal line 17 via a mixer 16 and a prescribed number of TV sets 5 are connected to the video signal line 17 and the TV sets 5 are arranged closely to each operation device 14. The operation device 14 gives a command of operation control/monitor of a load 1 and the central controller 15 gives a control signal of the load 1 to the terminal equipment 2 in response to the command and receives a signal relating to the operating state of the load 1 from the terminal equipment 2. Moreover, the information relating to the operating state of the load 1 is displayed on a screen of the TV set 5 via the video signal line 17. That is, the load 1 is controlled from other location than the central controller 15 by the operation of the operation device 14. |
