Abstract

PURPOSE:To improve operation efficiency and to improve the reliability of a system by turning off and then on a power source automatically if trouble occurs in an information processor. CONSTITUTION:A power source controller for the information processor is equipped with an AC input circuit breaker 6, the various-status display 7 of a power source part, and the operation part (encircled with a dotted line in figure) of a repetitive power-on circuit on the console panel. This operation part is equipped with three-digit hexadecimal digital switches 1-3, and sets an on-timer after the power source is turned on, an off-timer after the power source is disconnected, and the number RT of times of repetition. Further, a repetitive power-on mode is entered with a lock type push-button switch 4 pressed and a display element 5 displays the number of times of repetitive power-on operation. Consequently, if abnormality is detected during system operation, for example, a control system indicates the system error and then a repowering-on flag is set to generate a power-off signal, thereby cutting off the output of the power source.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an X-direction control device for an information processing device.

[Conventional technology]

In a relatively medium to large scale information processing apparatus, after the power is turned on, each control unit and input/output device of the information processing apparatus sequentially starts up the system. If an abnormality occurs in the control unit or input/output device during start-up or after the start of operation, some kind of abnormality notification will be output or displayed and the system will stop (system down). Alternatively, in the case of a program stall, etc., the system will go down without any formal abnormality notification.

In such cases, with conventional information processing equipment, an operator or maintenance person intervenes to remove the cause of the abnormality, remove the abnormality, and then turn on the power again to start up the system. .

[Problem that the invention seeks to solve]

Abnormalities or damage to information processing equipment can be classified into fixed failures caused by component failures and intermittent failures caused by soft errors in memory or file devices, for example. In relatively large systems, it is thought that the frequency of occurrence of intermittent jibara is rather large. Furthermore, in most cases, intermittent failures can be recovered by turning the power off and on again.

In conventional information processing apparatuses in which the above-mentioned maintenance burden is used to cope with system downtime, maintenance personnel are recalled when such intermittent failures occur, and it takes a considerable amount of time to restart the system. In particular, unmanned operating systems have the disadvantage that they require valuable time and a great deal of effort until the system is ready to operate, since no operators or maintenance personnel are always present.

Means for Solving Problems] In the m-source control device of the information processing device of the present invention, after the power is turned on, a normality notification signal from the load-side control system that supplies the output is generated within the set time of il. If not, the first means of disconnecting the IL source is to output the power again after the set time of apprentice 2, and the pre-distribution is performed by a notification signal from the load-side control system while the pre-distribution@ is being supplied. The power source is configured to include a second means for disconnecting the @, and a means for outputting the pre-distributed power again after a second set time after the power source is disconnected by the first and M20 means.

〔Effect of the invention〕

As explained above, the present invention automatically turns off and turns on the power when a failure occurs in an information processing device, thereby enabling automatic recovery in the event of an intermittent failure and increasing the operating efficiency of the information processing device. This has the effect of improving the reliability of the system and reducing maintenance costs.
