Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention provides power-on of a computer, etc. based on date information and time information, or a power-on/off command sent from a remote computer, etc. via a communication line. / A power-on signal generated by pressing a power-on switch of the computer, etc. and a power-off signal generated by pressing a power-off switch of the computer, etc. are inputted, The present invention relates to an operating power supply control device that turns off/on the power of the electronic computer, etc., using these signals as well.

[Prior art and problems]

Conventionally, when operating a computer unattended, (a) power is turned on/off based on date and time information, etc.

(b) Power is turned on/off in response to a power on/off command from a host computer connected via a communication line.

There were two methods. When operating an operating power supply control device using these formulas connected to a computer, the power on/off of the computer will be controlled in addition to the above (a) and (b) controls during unmanned operation, as well as during manned operation. Normally, this can be done by the computer's own power-on switch or by a switch on the operating power supply control device.

Conventionally, when powering on/off a computer locally in this way, a signal from the power on/off switch of the computer itself is input to the operating power supply control device, and the operating power supply control device detects this and turns on the computer. There are systems in which the device itself detects a signal from a local power on/off switch on the operating power supply control device and turns it on/off. However, in these systems, unless the operating power supply control device is in an operable state, it is not possible to locally turn on/off the power to the computer. For example, if the power supply control device for operation goes down due to a failure, even if you want to use the computer locally, remove the power supply control device for operation from the computer and turn the power on/off switch of the computer itself. It cannot be used unless it is directly connected to the power supply. If the operating power supply control device goes down, the user of the computer should contact the manufacturer's customer engineer, etc., and the customer engineer will remove the operating power supply control device and turn the power on/off switch to the computer's power supply section. A situation has arisen in which local use is not possible unless the device is connected directly to the computer or the operating power supply control device is repaired.

[Purpose of the invention]

The present invention is intended to eliminate such drawbacks, and is to provide a power on/off signal from a power on/off switch of a computer when the operating power supply control device becomes inoperable due to a failure or the like. The object of the present invention is to provide an operating power supply control device that allows direct input to the power supply section of an electronic computer.
