<p>PURPOSE:To interrupt the power supply and to apply the power supply again without visit to a remote equipment installation location even when a fault including the software takes place in the remote information processing unit and the power supply cannot be interrupted. CONSTITUTION:When a CD signal ON detection circuit 11 detects ON of a CD signal and a system power supply application command signal 107 is outputted from a power supply control instruction circuit 12, an instruction output storage circuit 13 stores it that the application instruction of the power supply is outputted to give a pattern detection command to an ON-OFF pattern detection circuit 14. The ON-OFF pattern detection circuit 14 uses a prescribed time OFF detection circuit 15 and a prescribed time ON detection circuit 16 to detect a time series pattern when the CD signal is set to be OFF-ON-OFF for a predetermined time and allows the power supply control instruction circuit 12 to output a system power supply interrupt instruction signal 108 thereby interrupting the system power supply.</p> |
