Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an automatic operation control device for an information processing device, and more particularly to power-on control during automatic startup of a computer system.

Summary of the Invention In an automatic operation control device that performs power on/off control of a computer system, the cause of the previous power off is stored in an external storage section, and when the power is turned on, the contents of the external storage section E are read out and the power is turned off. By determining whether or not to invest,
This is intended to prevent the power from being turned on in an abnormal environment.

Conventional technology Conventionally, the trigger for system disconnection of this type of automatic operation control device is generally the input of a system power off command due to the operation management program detecting the end of a job, the expiration of the scheduled disconnection time by a timer, or a system abnormality. Forced disconnection due to detection, occurrence of external environmental abnormality (e.g. occurrence of earthquake, fire, etc.)

(temperature, humidity abnormality, water leakage, power frequency abnormality, etc.)
These are the triggers for turning off the power to the system and ending the day's operation.

To restart operation the next day, the power to the system is automatically turned on when the start reservation time set in advance in the turn-on reservation timer arrives.

Problems with the Conventional Technology The conventional automatic operation control device described above simply turns on the power mechanically according to the reserved time set in the power-on reservation timer, regardless of the cause of the power cut on the previous day. There is a drawback that the power is turned on even when the process is still continuing.

Purpose of the Invention The purpose of the present invention is to solve the above-mentioned conventional drawbacks, and to make automatic driving more reliable and safe by preventing the power from being turned on unnecessarily even after the reserved time, depending on the cause of the power cut on the previous day. It is in.

Embodiments of the Invention Next, the present invention will be described in detail with reference to the drawings.

The figure is a block diagram showing one embodiment of the present invention. That is, the automatic operation control device i includes a power supply control unit 4 that controls power on and off of the computer system 11 according to instructions from the microprocessor 2, a startup instruction unit 3 that instructs startup of the computer system 11, and an electronic Input/output control unit 5 for exchanging information with the computer system 11
, an external storage unit 6 for storing the cause of power-off of the computer system, a display panel 7 for displaying the contents of the external storage unit 6, and an environmental status input unit for inputting the external environmental status of the computer system. 8, and a disconnection reservation timer 9 for setting a power-off time.

A power-on reservation timer O for setting the power-on time;
When activated by the input reservation timer 1G, the availability of the power supply official is determined based on the state stored in the external storage section 6, and the computer system 11 is processed via the power supply control section 4.
A microprocessor that starts up the computer system 11 via the startup instruction section 3 after turning on the power to the computer system 11, and then controls each section according to instructions from the computer system 11 inputted via the input/output control section 5. It consists of 2.

The display panel 7 is located at a remote location.

Next, the operation of this embodiment will be explained. To make the explanation easier, we will first explain the operation after the system starts up. When the system starts up, the system 7
The computer system 11 instructs the automatic operation control device 1 to set a reserved time for system power-off for the current day and a reserved time for power-on for the next day. The above command is decoded by the input/output control unit 5 and notified to the microprocessor 2.

Set the scheduled disconnection time for the specified day in the disconnection reservation timer 9, and set the next day's power up time in the power-on reservation timer 10. Normally, the system power-off operation is performed by the operation management program running on the system. Therefore, the power cut-off according to the cut-off reservation time set in the cut-off reservation tie 29 is used as a safety valve in case the system cut-off instruction is not inputted for some reason in the program.

Normally, when the operation management program detects the completion of the day's operation, a power-off command from the computer system 11 is input to the input/output control unit 5. The input/output direction W unit 5 decodes and recognizes the above command and notifies the microprocessor 2, and the microprocessor 2 stores in the external storage unit 6 that the disconnection is due to a power disconnection command, and then outputs the power control unit 4. Power off the system via The contents of the external storage section 6 are 1
displayed on the display panel 7.

When an abnormality occurs in the external environment (1) Various sensors (not shown) detect abnormalities such as power supply abnormalities, earthquakes, occurrence of fire, abnormalities in temperature, humidity, or water leaks, and send the status to the environmental status input section 8. Let them input. The environmental status input unit 8 reports to the microprocessor 2, which determines whether the circumstances require an emergency disconnection of the system power, and if so, determines the cause. The contents of the external storage section 6 are stored in the external storage section 6 and the power supply cut-off instruction is issued via the power supply control section 4. The contents of the external storage section 6 are displayed on the display panel 7.

By defining in advance in the memory of the microprocessor 2 whether or not various external environmental abnormalities will cause the system to be disconnected, the microprocessor 2 can easily determine whether or not to disconnect the power. .

Next, the next day's system power-on operation will be described.

First, when the reserved time set in the input reservation timer 10 comes, the input reservation timer 10 notifies the microprocessor 2 of this fact. When the microprocessor 2 receives the notification from the power-on reservation timer 10, it reads out the cause of the previous day's power-off stored in the external storage section 6, judges its contents, and determines whether or not to turn on the system power. The conditions are:
It is defined in advance in the storage section of the microprocessor 2.

When the microprocessor 2 determines that the system power can be turned on, it issues an instruction to turn on the system power through the power control unit 4. After that, the power control unit 4 detects the completion of the system power-on operation and notifies the microprocessor 2, and the microprocessor 2 starts the system through the startup instruction unit 3.If it is determined that the power cannot be turned on, the system power is turned on. Of course not.

Therefore, if the system power was turned off the previous day due to an abnormality in the external environment, the power will not be turned on.
If an abnormality in the external environment continues,
It is possible to prevent the power from being turned on even after the reserved time has arrived.

Effects of the Invention As described above, in the present invention, the cause of the system power-off on the previous day is stored in an external storage section, and when the power is turned on the next day, the contents of the external storage section are read out to determine whether or not to turn on the power. This configuration has the effect of realizing safe and reliable automated driving. In addition, since the cause of system power-off is displayed on a display panel located at a remote location, maintenance personnel can quickly and accurately respond to abnormal power-offs.
You can take l.
