Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention provides an information device in which, when controlling the power supply of the device constituting the device according to the setting of the power supply state changeover switch, the state is changed to the power supply state when the power is turned on again. The present invention relates to an information device characterized by having a mechanism for returning to the state immediately before being turned off, and capable of continuous use regardless of whether a power supply state changeover switch is turned on or off.

[Prior Art] Conventional information equipment generally turns on and off power supply to each device in the equipment in response to a power supply state changeover switch. Therefore, each time the switch is turned on, the information equipment initial start-up means is executed, making it impossible to continue using the information equipment. This is due to the fact that when the power supply is cut off, each initial device of the information equipment loses the setting state information at that time. As a way to avoid this, it is possible to supply power to all the devices in the configuration, but this method has the drawback of constantly consuming power, so it cannot be said to be a very useful method. The available mechanisms are disadvantageous and have major drawbacks, as they are required in mobile computers such as laptop computers, which have significant power supply limitations.

[Problems to be Solved by the Invention] In order to solve the above-mentioned problems, an object of the present invention is to store setting information for each device in an information equipment configuration, and to check the status of each device in the configuration when the power is turned off and on. An object of the present invention is to provide an information device equipped with a mechanism for saving and restoring settings.

[Means for Solving the Problems] The present invention provides each device constituting an information device, a state setting information storage means when using the device, a power switch for controlling the power supply of the information device, and a power switch for controlling the switch. It is characterized by comprising a state change detection means, and an information equipment configuration device setting information storage/restoration means for saving and restoring the storage of the information equipment configuration device setting information storage.

[Embodiment] An information device of the present invention will be explained based on FIG. 1.

First, an information equipment configuration device setting information storage means A is provided in order to store setting information for each device configuring the information equipment that is in use at any time, not only in the information equipment.

The information device has a power switch B, and furthermore,
Information equipment power switch state change detection means C is provided for detecting changes in the switch state. When the user requests to change the power supply state of the information equipment using the above-mentioned power switch state change detection means C, when the power supply itself is controlled, the information equipment configuration device setting information saving/restoring means causes the information equipment to be powered off. The processing necessary for continuous use regardless of changes in switch B is performed based on the information stored in the component device setting information storage means A.

In FIG. 2, information equipment is constituted by 1 to 7. 1 is a CPU that controls the information equipment, and 2 is each device of the information equipment that is controlled by the OPU. 6 is a power switch for controlling the power state of the information device.

For the information equipment configured in this manner, the device setting information storage means 6 for each of the configurations described above is provided. Further, in order to detect a change in the setting of the power switch, a device power state change detection means 7 is provided. Reference numerals 4 and 5 represent means for saving and restoring setting information of information equipment components and hardware for storing the information for control when a power switch change is detected.

Next, the operation of the information device configured as described above will be explained based on FIG. 3.

When the information device is reset and powered on, the information device initialization program is started, and thereafter, necessary processes are sequentially executed. Here, when some state setting data is output to each device/port of the information equipment, that data is stored in the data storage means 4. If the power state does not change, the process of 2→5→2 is looped. Here, if a change in the power supply status is detected by 5, then 4
The data temporarily stored in the computer is saved to the storage hardware, and the power supply to the information device is stopped. In addition, 4
If the same hardware as that used in 7 is used as the temporary storage hardware in 7, there is no need to save the temporary storage data to the storage hardware in 7.

When a change in the power supply state is detected in the power off state, the power is turned on by the information device configuration device information storage and recovery means 10, and the configuration device setting information is retrieved from the storage hardware. Further, based on the same data, all the constituent devices are returned to the state immediately before being powered off, thereby making it possible to continue processing regardless of changes in the power supply state. At this time, when resetting configuration device setting information, the same setting information storage (-next storage) is also restored.

Here, an embodiment of the present invention will be explained using FIG. 6.
4 is / for each device in the information equipment configuration. This is a register for storing configuration data corresponding to the boat. Each device described below refers to hardware and devices constituting information equipment and equipment, such as a video controller, HDD controller, OPU register, RAM, FDD controller, serial controller, etc. Furthermore, this embodiment can also be realized by a mechanism in which a monitoring 0PU (slave OPU) watches over the timing of each process 10 processing by the CPU, and the same data is retained in a specific storage mechanism every time I10 processing is performed. can. Here, the specific storage mechanism refers to RAM, registers, external storage devices, etc. On the other hand, in an OPH such as 80586 where an interrupt is generated every time the process 10 is processed, the open interrupt processing means
4 can be realized by storing the I10 setting value in the specific storage mechanism. In general APA, 4 is achieved by having the 10 process performed within a specific processing procedure, and by ensuring that the same data is held in the specific storage mechanism when setting the 10 process in the 10 process in the same procedure. You can also do it.

On the other hand, as for 5 and 9, if the information equipment component device itself can set/read its setting information, the board of each device itself can perform the functions of 4.
This can be achieved using an interrupt mechanism that is triggered by switching the power switch.

It is also possible to implement a mechanism that polls the power switch state at specific timing.

The embodiment in 7.10 is shown using FIG. First, when the power switch changes from on to off (at 7 o'clock), setting information for each device in the information equipment configuration is saved in storage hardware, and then the power to devices that do not require power supply is turned off. The storage hardware referred to here includes HD'D, floppy disk, disk, RAM with power backup (including 0MO8RAM), and IC.
Refers to cards, punch cards, magnetic cards, etc. When the power switch transitions from off to on (at 10 o'clock), the power is set to 7, and the power is set to 7 for the component devices that were turned off.
After turning on, each device information saved from the storage hardware is reset to each device. Furthermore, each device setting value memory is restored using the method realized in 4.

The above functions are realized by the information equipment control software or hardware incorporating the same functions.

[Effects of the Invention] The present invention has a great effect of being used as a means that is designed to automatically detect the setting state of switches in information equipment, and the present invention can be used in conjunction with other peripheral terminal equipment as well. This idea can be applied.
