ど、運用上および保守上の欠点がある。Prior Art In a conventional power supply control device, in response to the stoppage of the control power supply, it is no longer possible to continuously send out a power-on instruction signal to a controlled device, and the device power is cut off. Even if an attempt is made to switch to local control of the controlled device itself and turn on the power while the control power supply is stopped, switching to local control may not be possible because the control power supply is stopped. Furthermore, even if you manually switch from external control (remote control) to local control, if you do not follow the operating procedures carefully, something that is powered on by remote control may be disconnected as soon as you switch to local control. There are drawbacks in terms of operation and maintenance, such as the fact that if the power is turned off under remote control, the power will be turned on immediately after switching to local control.

It is an object of the present invention to provide a power on/off control method that prevents malfunctions due to inconsistency with the state.

され、電源切断させる。 Referring to FIG. 1, in one embodiment of the present invention, the power to the power controlled device 2 of the unmanned station is controlled to be turned on/off by the external power control device 1 from a remote center via the modem line 10a. Ru. In response to turning on the carrier wave (carrier) for data transmission from a remote location, the modem 3 sends a carrier-on signal (CD) to the DC signal line 11a in the ON state. When the external power supply control device 1 detects the CD signal for a certain period of time, the power supply control device 2
The power on signal of the power on/off signal line 10b is turned on to turn on the power. Thereafter, in response to the processing in the power controlled device 2, a recovery instruction is given from the device 2 to the external power control device 1 via the power cutoff signal line 10d, and the external power control device 1 is restored. At the same time, a disconnection signal is sent to the power controlled device 2 via the power on/off signal line 10b, causing the power to be disconnected.

にオン（ON）状態にしておく必要がある。 Next, the operation of this device 1 will be explained in detail. When a CD signal is applied from the modem via the DC signal line 11a, it is received by the receiver 1a. Thereafter, the signal is checked for a certain period of time by the signal detection circuit 1c, and the flip-flop 1d for power-on confirmation is turned on. In response to the on state of the flip-flop 1d, the state memory relay MRL is operated via the relay driver 1e (the operating state is shown by a solid line), and the power-on instruction relay RL1 is operated.
restore. In response to the restoration of the relay RL1 (indicated by the restored state), the normally operating relay RL2's contact rl 2 (the normally operating state is indicated by the dotted line) is switched on via the contact rl 1 and the mote/local changeover switch contact SW. The power on/off signal line 10b connected to the control device 2 is turned on to turn on the power to the power controlled device 2. When the power is turned off normally, a disconnection signal is sent via the disconnection signal line 10d upon confirmation of the completion of the operation of the power-controlled device 2, and a disconnection signal 1g is received via the detection circuit 1f. In response to this reception, the power-on confirmation flip-flop 1d turns off (OFF), restores the status memory relay MRL, and operates the power-on instruction relay RL1 (the operating state is shown by a solid line). In response to this operation, the contact rl1 operates, the power on/off signal line 10b is disconnected, and the power to the power controlled device 2 is cut off. Now, in the normal operation, the power controlled device 2
When the control power of the external power control device 1 is cut off while the power is turned on, the relay RL1 remains in the restored state (the restored state is shown by a solid line), and the relay RL2 is restored (the restored state is shown by the solid line). The local control switch of the power controlled device 2 is connected via the contacts of the latching type relay MRL that continues to operate during power outages.
Switched to SWA and continues power-on signal.
Furthermore, when the control power of the external power control device is cut off while the cutoff signal is being sent to the power controlled device 2, the state memory relay MRL has been restored (the restored state is shown by a solid line). For this reason, relay RL1,
Even when RL2 is in the recovery state, the power on/off signal line 10b is disconnected at the contact mrl. Therefore, the local control switch of the power controlled device 2
No matter what state SWA is in, incorrect input can be avoided. In addition, when it is desired to turn on the power to the power-controlled device 2 by local control in such a recovery state, the remote/local changeover switch SW can be switched to the L side (local side). As a result,
The circuit of the external power supply control device 1 is disconnected and can be turned on/off under local control. Furthermore, in order to guarantee remote control operation from the external power supply control device 1, it is necessary to keep the local control switch SWA always in the ON state.

This has the effect of enabling easy-to-operate power on/off control without interruption of the device power supply.
