PURPOSE:To apply the ON/OFF control of an electric device over a wide range of multiple purposes by using various sensors as well as a timepiece circuit. CONSTITUTION:A system bus 1 contains a CPU2 which controls the entire system, an ROM including a program to attain the overall system specifications, an RAM4 for working areas and display, a display controller 5 which controls a CRT6, a keyboard, etc. An electric device is basically controlled with the time by a timepiece circuit 14. It is also possible to receive the signals from various sensor interfaces 9 such as an alarm, a smoke sensor, a gas sensor, an alarm for water leakage, a visitor sensor, etc. The time and the control of various sensors are combined by an external memory 11. Thus the control of the electric device is possible for a wide range of multiple purposes. |
