Abstract

PURPOSE:To set priority on a control execution task side higher than that on a state supervisory task side in an operating system provided with a state supervisory task to collect alarm information, and a control execution task to execute control based on the result of a state change analysis task. CONSTITUTION:The state supervisory task 4 supervises an alarm by periodic rising, and stops its own operation by starting up the state change analysis task 1 and informing state change data (a) when detecting change. The state change analysis task 1 starts up the control execution task 2 after executing control execution, and stops its own operation after informing control data (b), and the control on a generated alarm is executed by the control execution task 2. After the control is executed by the control execution task 2, the state supervisory task 4 restarts alarm supervision by the periodic rising, and repeats such processing.

The operating system in the information processing apparatus of this example includes a status monitoring task 4 for collecting alarm information at an arbitrary time, and an initial setting task 3 for initializing and changing the settings of the status monitoring task 4 and the apparatus. A state change analysis task 1 that receives each state change data from and to analyze the information, and a control execution task 2 that executes control with the same priority as the state monitoring task 4 based on the information of this state change analysis task 1. And the actions of the individual tasks have flag A
5, the flag B6 is referred to.

When a failure occurs in the information processing apparatus, the alarm information is first collected by the status monitoring task 4 activated by the periodic wakeup, and the status change analysis task 1 is executed.
On the other hand, the plug A5 is turned on and the state change data is transferred. In the state change analysis task 1, after the state change analysis, the flag B6 is turned on for the control execution task 2 to execute the control for the generated alarm, and after the control is executed, the flag B6 is cleared for the state change analysis task 1 and processed. To finish.

[0005]

In this conventional information processing apparatus, the status monitoring task and the control execution task execute monitoring control with the same priority, and the operation of each task is performed by referring to the flag. Since the status monitoring task collects alarm information and the control execution task ends the control, it is necessary to refer to the flag many times in the series of monitoring control operations. If the condition analysis task clears the flag for the status monitoring task before the control execution task starts control, if the status monitoring task accepts the next alarm without executing control for the alarm that has occurred However, there is a problem that processing cannot be made consistent in a series of supervisory control operations.

It is an object of the present invention to perform an initialization task and a state monitoring task which are tasks for transferring state change data, and a state change analysis task and a control execution task which are tasks on the control side by receiving state change data. It is to provide a supervisory control method of an information processing apparatus that makes the processing consistent as a system by setting a priority between the and.

[0007]

A monitoring control method for an information processing apparatus according to the present invention includes a status monitoring task for notifying as first status change data when there is a change in an alarm collected at a predetermined time. An initial setting task for notifying as second state change data when there is a change in the initial setting and the setting change of the information processing apparatus due to a request from the monitoring apparatus, and the first and second state change data. An operating system comprising a state change analysis task for receiving and analyzing, and a control execution task for executing control with a higher priority than the state monitoring task based on the information of the state change analysis task, the control system comprising: The operation of the state monitoring task is stopped while the execution task is executing the process.

While the state change analysis task and the control execution task are set to a higher priority than the initial setting task, while the control execution task is executing processing based on the information of the state change analysis task. Stops the processing of the initialization task.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a supervisory control system of an information processing apparatus of the present invention.

The operating system of the information processing apparatus according to the present embodiment includes a status monitoring task 4 for notifying as a first status change data a when an alarm collected at a predetermined time has changed, and a monitoring apparatus. When the initial setting task 3 for notifying as the second state change data c when the initial setting and the setting change of the information processing device are changed by a request from the It is composed of a state change analysis task 1 to be analyzed, and a control execution task 2 which executes control with a higher priority than the state monitoring task 4 based on the information of the state change analysis task 1.

The state monitoring task 4 monitors an alarm by periodically waking up, and when a change is detected, the state change analysis task 1 is activated to notify the state change data a and stop its own operation.

The state analysis task 1 activates the control execution task 2 after executing the analysis, stops its own operation after notifying the control data b, and the control execution task 2 executes control for the alarm generated.

After the control execution task 2 executes the control, the state monitoring task 4 restarts the alarm monitoring by the periodic wakeup and repeats the above processing.

As described above, according to the present embodiment, the priorities are set among the individual tasks, for example, the control execution task 2 is set to have a higher priority than the status monitoring task 4, so that several flags are referred to in the conventional method. It is possible to eliminate the annoyance of performing the above, and to avoid the operation in which the status monitoring task 4 accepts the next alarm without executing control for the alarm that has occurred.

Further, in this embodiment, by giving the state analysis task 1 and the control execution task 2 higher priority than the initialization task 3, the initialization task 3 changes the device settings and initializes the flags and the memory. When a request for activation processing is generated, the priority of the state analysis task 1 and the control execution task 2 is higher than that of the initialization task 4, so the operation of the initialization task 3 is stopped while the control execution task 2 is operating. .

As a result, the trouble of referring to the flag is eliminated, the phenomenon that the initial setting task 3 holds a new setting request before executing the control can be prevented, and the system can be provided with consistency of processing. .

[0017]

As described above, according to the present invention, the initial setting task and the state monitoring task, which are the tasks on the side of passing the state change data, and the state change task, which is the task of receiving and controlling the state change data. The priority is set between the analysis task and the control execution task, and the alarms are not collected by stopping the operation of the low priority task during the execution of the high priority task.

Therefore, it is possible to avoid a situation in which the control execution task unnecessarily collects alarms before starting processing, and as a result, extra control is avoided, and the system is made consistent in supervisory control processing. It has the effect that

Further, the troublesomeness of the flag reference by the conventional method is eliminated, the phenomenon that the initial setting task 3 holds a new setting request before executing the control is prevented, and the system is provided with the consistency of processing. It has the effect of being able to.
