Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power supply control system for turning on / off a power supply of various electric equipment including an office automation equipment such as a computer by a signal from the outside,
In particular, turn on / off multiple electrical devices in a specified order and at intervals.
The present invention relates to a power control system having a function of being able to perform F and detecting ON / OFF of an electric device.

2. Description of the Related Art For example, when activating a computer system in which a plurality of peripheral devices are connected to a computer, first the peripheral devices such as an external storage device and a measuring device connected to the computer are powered on, and then these It is often the case that the computer is turned on at the end after the peripheral devices are booted normally. Conventionally, as a power supply controller for automatically starting such a computer system at a specified time, there has been a power supply controller that sequentially turns on the power supply to a plurality of devices at regular intervals.

However, since there are various kinds of peripheral devices connected to a computer, it is necessary to switch the order of powering on or to power on only a part of many devices depending on the case. .. Also, there is a large or small difference in the time from power-on to normal startup depending on the peripheral device. For example, in the case where it takes a long time to stand by even if the power is turned on, or in the case of a peripheral device with a built-in self-diagnosis circuit, it takes a considerable amount of time from the time the power is turned on to the normal startup state. It costs.

[0004]

However, the conventional power supply controller is inconvenient because the power-on sequence and intervals are constant, and it is not possible to power on only some devices. In addition, since it is not possible to set the power-on time individually according to the startup time of various peripheral devices, the computer will start up before the peripheral devices are in a normal startup state, and some peripheral devices may There was a problem when it was not installed properly in the computer. To avoid this problem, set the power-on interval to a large value depending on the peripheral device that takes the longest time to start up, but doing so will take a long time to start up the computer system. bad.

Further, even though the power is turned on by the power controller, the power switch of the electric device is turned off.
The device may not be activated due to the FF, but since the conventional power supply controller cannot notify this, there is also a problem that the system is erroneously operated as it is.

An object of the present invention is to be able to automatically turn on / off a computer and its peripheral devices, and to arbitrarily select a power-on sequence, a power-on interval, a device to be powered on, and the like. It is an object of the present invention to provide a power supply control system capable of monitoring the activation state of electric equipment when the power is turned on.

[0007]

According to a first aspect of the present invention, there is provided a power supply control system for turning on / off power supplies of two or more outlets 2 for supplying electric power to an electric device 1. The control circuit 4 controls each outlet 2 via the control circuit 4, and the current detection circuit 5 detects ON / OFF of the electric device 1 connected to each outlet 2. In the power supply control system according to the second aspect of the present invention, the operation state of each electric device 1 detected by the current detection circuit 5 is displayed on the display device 6.

[0008]

In the power supply control system according to the first aspect of the present invention, the control circuit 4 individually controls ON / OFF of the plurality of outlets 2 via the power supply ON / OFF circuit 3. The power-on sequence and the power-on time interval of each electric device 1 which is supplied with power can be freely changed only by changing the setting of the control circuit 4. Moreover, since the current detection circuit 5 detects the current flowing in each outlet 2, the ON / O of each electric device 1 is turned on / off.
You can check the FF. In the power supply control system according to claim 2 of the present invention, since the operation state of each electric device 1 detected by the current detection circuit 5 is displayed on the display device 6, the electric device 1 is turned ON / O as set.
It is possible to judge at a glance whether FF has been performed.

[0009]

FIG. 1 shows an embodiment of the power supply control system of the present invention. In FIG. 1, 1 is an electric device such as an office automation device.
In particular, it is a computer or a peripheral device connected to the computer. Reference numeral 2 in the figure is an outlet for supplying electric power to the various devices 1, and the outlets 2 are attached to a metal or synthetic resin casing 10 in which main electric circuits constituting the power supply control system are housed. Has been. A power ON / OFF circuit 3 and a current detection circuit 5 are housed in the housing 10, and a display device 6 is also attached to the front of the housing 10. This display device 6
May be separate from the housing 10 and may be installed separately in a place where a person who manages each electric device 1 can easily see it.

Reference numeral 4 in the figure is a control circuit, which is an input device for setting and inputting ON / OFF time of each outlet 2, a segment for displaying input data from the input device, and A memory for storing the input data of the input device, and a process of reading the data by reading the data from the memory and turning the power ON / OFF to the power ON / OFF circuit 3.
It is composed of a CPU that outputs signals,
In this embodiment, an existing computer is used as the control circuit 4 instead. Reference numeral 3 in the same figure is a power ON / OFF circuit that switches an internal relay by an ON / OFF signal output from the control circuit 4 to supply or stop a current to a designated outlet 2.

Reference numeral 5 in FIG. 1 is a current detection circuit for detecting the current flowing through each of the outlets 2. The detection circuit 5 has a display device 6 for displaying the detection result.
It is provided for each. As the display device 6, a two-color light emitting diode is used. The light emitting diode does not emit light when the outlet 2 is in the OFF state, is turned on by the ON signal from the control circuit 3, and lights up in green when the electric device 1 connected to the outlet 2 is activated. However, despite the fact that the ON signal is output from the control circuit 3 and the outlet 2 is in the ON state,
Lights yellow when no current flows to the outlet 2.

[0012]

By using the power supply control system of the present invention, it is possible to set the ON / OFF sequence and intervals of the electric devices 1 for each outlet 2, so that a plurality of electric devices 1 such as a computer and its peripheral devices can be set. It is safe because the system can be automatically started up, and the display device 6 can monitor whether each electric device 1 is started or stopped as set.
