Abstract

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.

そのままになっているという欠点がある。The conventional remote power control device described above has the feature that it can be controlled without being aware of the existence of the remote power control device from the HOST side.
The convenience of not having a control relationship with the remote power control device on the HOST side is that, on the other hand, if a fault occurs in the remote information processing device, which is a terminal or network node, including software, remote control can turn off the power. The disadvantage is that the equipment remains in place until the maintenance worker travels to the remote location where the equipment is installed and takes action.

A detection signal 104 is output. When the power supply control instruction circuit 12 receives the carrier ON detection signal 104, it outputs the system power supply instruction signal 107 to the power supply device 31, and outputs the power supply program disconnection instruction signal 106 from the disconnection instruction reception circuit 17 or the ON-OFF pattern detection circuit 14. When receiving the pattern detection signal 112 from the
Outputs 08. When the system power-on instruction signal 107 is output, the instruction output storage circuit 13 stores that the system power has been turned on, and also outputs a power-on state display signal 109 indicating that the system power has been turned on.
Output. Furthermore, when the system power-off instruction signal 108 is output, the system power-on memory is reset, and the output of the power-on state display signal 109 is cut off. While receiving the power-on state display signal 109, the ON-OFF pattern detection circuit 14 detects a time series of patterns represented by OFF-ON-OFF of a certain length of time of the CD signal, and detects this time series. Then, a pattern detection signal 112 is output. The fixed time OFF detection circuit 15 and the fixed time ON detection circuit 16 are ON-OFF.
The pattern detection circuit 14 detects the OFF state for a certain period of time and the ON state for a certain period of time of each carrier signal for detecting a pattern, and when detected, sends an OFF detection signal 110 and a certain period of time to the ON-OFF detection circuit 14, respectively. A time ON detection signal 111 is output. As shown in the explanation of FIG. 2, the disconnection instruction receiving circuit 17 receives the power disconnection instruction signal 105 that is normally output from the power disconnection command detection circuit 33 upon termination of the operating state, and outputs the power program disconnection instruction signal 106. do.

When the carrier detects that some kind of failure, including software, has occurred in the remote information processing device that is a terminal or network node, the carrier closes, opens, and closes the line to the remote information processing device. Turns the signal off-on-off. By detecting this off-on-off, the power to the remote information processing device is cut off, so if it becomes impossible to turn off the power due to a fixed failure, the power can be cut off without having to go to the installation location of the device. This has the effect of increasing the probability that the system will be able to continue operating by restarting the system.
