Automatic power supply cut-off controlling unit

Abstract

Abstract PURPOSE: To secure an unmanned automatic operation as well as a labor-saving automatic opertion for the information process system by providing the automatic power supply cut-off control unit to make the power supply control unit deliver the power supply cut-off indication via the power supply cut-off order give from CPU. CONSTITUTION: Automatic power supply cut-off unit 8 is installed as a component element of information process system 6 and then connected to input/output processor 3 via point A as well as to power supply control unit 7 via point B. When system 6 completes a series of processes in the normal way,the program within CPU 1 gives the power supply cut-off indication to unit 8 through the normal completion of the process. Unit 8 receives the order via point A and interface part 9 and decodes (10) the order to display (15) the power source cut-off based on the normal completion, and also transmits the power supply cut-off indication signal to unit 7 via power supply cut-off indication part 14 and point B to cut off the power supply for each component element of system 6. At the same time, the power supply for the electric lamps, the air conditioners and others in the station is cut off by the cut-off signal sent from part 14 COPYRIGHT: (C)1979,JPO&Japio
