Abstract

PURPOSE:To discover the fault of a hardware in advance and to prevent it by storing and outputting the number of times for executing retry processings according to the fault of the hardware in the case of an information communication processing or write processing. CONSTITUTION:When a relevant processing is not normally executed by the fault of the hardware, '1' is added to the value of an E<2>PROM 9 at present and the value of a retry counter is counted down only by '1'. Then, the relevant processing is executed again. When the relevant processing is not normally carried out even by re-execution, the above-mentioned operation is repeated. When the relevant processing is not normally executed even after the value of the retry counter is turned to '0', an error message is displayed on a liquid crystal display 14. When the value exceeds a value set in advance after updating the E<2>PROM 9, a warning message is displayed on the liquid crystal display 14.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an information processing apparatus, such as a personal computer or a word processor, which is equipped with peripheral equipment such as a printer and a floppy disk device.

[Prior Art] Generally, in this type of information processing device, an abnormality occurs in the hardware during information communication processing with a printer, etc., or during information writing processing to a floppy disk, etc., and the corresponding processing is not performed normally. If the process is not successful even after several attempts, an error will occur. However, if the abnormality is avoided after several attempts, there will be no record of whether or not there was an abnormality in the hardware, and the process will be processed as if it had operated normally from the beginning. Therefore, it has been impossible to later investigate temporary hardware abnormalities that were avoided by retry processing.

By the way, if such temporary hardware abnormalities are accidental, there is no particular problem, but if they occur intermittently, they may lead to hardware failure. In particular, a failure of a floppy disk device or a hard disk device may lead to loss of necessary information, and prompt action is required.

[Problems to be Solved by the Invention] However, with conventional devices, it is impossible to later investigate temporary hardware abnormalities that occur during information communication processing with a printer, etc., or information writing processing to a floppy disk, etc. Therefore, it was difficult to detect hardware failures in advance and take appropriate measures.

Therefore, the present invention makes it possible to check later whether or not retry processing was performed due to a temporary hardware abnormality during information communication processing with a printer or the like or information writing processing to a floppy disk, etc., thereby preventing hardware failures in advance. The purpose is to provide an information processing device that can detect and prevent such problems.

[Means for Solving the Problems] The present invention provides an information processing apparatus that performs communication processing or writing processing of information to peripheral devices such as a printer or a floppy disk device. The apparatus includes a storage means for storing the number of times retry processing has been performed due to an abnormality, and an output means for outputting the number of retry processing stored by the storage means.

It is advantageous to provide a warning means that warns that there is an abnormality in the hardware when the number of retry processes stored in the storage means reaches a certain value.

[Operation] By taking such measures, when retry processing is performed due to a hardware error during information communication processing with a printer, etc. or information writing processing to a floppy disk, etc., the number of retry processing is stored in the storage means. be remembered. The number of times of try processing is stored by the storage means and output by the output means. Therefore, even if a hardware error is avoided through retry processing, it is possible to confirm that there is a temporary hardware error based on the output from the output means or the number of try processing, and this allows you to prevent hardware failure in advance. Be able to detect and take appropriate measures.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the information processing device of this embodiment, which is a floppy disk device (FDD).
) 1 etc., a signal cable 3 is connected to the information processing device main body 2 having
The printer 4 is connected to the printer 4 via the printer 4.

The information processing device main body 2 includes a CP that constitutes a main body control section.
U (Central Processing Unit) 5 is connected via a path line 6 to each storage section of ROM 7 in which programs for information processing are stored, ROM 8 for character generator, E2PROM 9, and RAMI O in which various processing information is stored. , a keyboard controller 12 that inputs key signals from the keyboard 11, a floppy disk controller (FDC) 13 that inputs and outputs data to and from the floppy disk device 1, and outputs display data to a liquid crystal display (LCD) 14. a display controller 15 that controls data transmission and reception performed with the printer 4 via the signal cable 3; a printer interface 16 that controls data transmission and reception performed with the upper host computer via the R5232C line; Each input/output control unit such as the R5232C interface 17 is connected to the R5232C interface 17.

Here, the E2FROM 9 is for storing the number of times retry processing is performed due to an abnormality in the hard disk, for example, in the processing of communicating information to the printer 4 or the processing of writing information to the floppy disk 1.

On the other hand, the printer 4 uses a CPU constituting a printer control section.
18, a ROM 20. A ROM 21 for a character generator, a RAM 22 including an image memory, an interface 23 that controls data transmission and reception between the information processing device main body 1 and the signal cable 3, and a head driver 2 that outputs print data to the print head 24.
5. Carriage motor 26. A motor driver 29 is connected to drive and control the ribbon motor 27 and the feed motor 28, respectively.

Therefore, the CPU 5 of the information processing device main body 1
When receiving an instruction to save the data on RAM 10 to a floppy disk by the program stored in M7, or when receiving an instruction to send data on RAM 10 to the printer 4, the processing routine shown in the flowchart of FIG. 2 is executed. .

That is, first, a retry counter (RTC) secured in RAM 10 is predetermined or initialized to the number of tries x1. Next, processing is executed according to each command, but if the corresponding processing is not performed normally due to a hardware error, "+1" is added to the current value of E2FROM9 to update the contents of E2FROM9. The value after the addition is rewritten (in the storage means), the value of the retry counter is counted down by "-1", and the corresponding process is executed again. If the hardware abnormality is avoided by this re-execution and the corresponding process ends normally, the process exits from this process routine.

On the other hand, if the hardware error cannot be avoided even after re-execution and the corresponding process is not performed normally,
2 Repeat updating the value of FROM9 and counting down the retry counter. Even if the value of the retry counter becomes "0", that is, if the corresponding process is not performed normally even after X1 retry processes,
- Display an error message on the liquid crystal display 14 to the effect that the corresponding process was not performed normally due to an abnormality in the software, and exit from this processing routine.

Also, after updating the value of E2FROM9 1. If the updated value exceeds the preset value X2, a warning message indicating that there is an abnormality in the hardware is displayed on the liquid crystal display 14 (warning means). In this state, the retry counter is counted down and the corresponding process is re-executed.

Further, when a key signal is input from the keyboard 11, the CPU 5 of the information processing apparatus main body 1 determines the type of the key signal and executes processing according to the key signal. here,
When a key signal instructing inspection of the E2FROM 9 is input, as shown in FIG. The total number of times retry processing has been performed is displayed on the liquid crystal display 14 (output means).

In the information processing apparatus of this embodiment configured as described above, each time a retry process is performed due to an abnormality in the hard disk in the process of communicating information to the printer 4 or the process of writing information to the floppy disk 1, the contents of the E2FROM 9 are It is rewritten by adding "+1" at a time.

In other words, the E2 FROM9 has a preset value of X.
The number of times of glue try processing when the hard disk error is not avoided even after one try of glue processing, and the number of glue try processing when the hard disk error is avoided by up to X1 number of glue tries and the corresponding process is performed normally. In this way, the number of past glue try processing times is added up. The contents of the E2FROM 9 are displayed on the liquid crystal display 1 by operating a predetermined key on the keyboard 11.
4 can be displayed.

Therefore, even if a temporary hardware error has been avoided through retry processing, a record will be left in the E2FROM9, so by periodically checking the contents of this E2FROM9, it is possible to detect any hardware abnormalities. It becomes possible to accurately grasp the occurrence status of retry processing. As a result, it becomes possible to detect failures that may occur due to deterioration of the hardware condition in advance and take appropriate measures.

In addition, in the device of this embodiment, when the value of E2FROM9 exceeds the preset value X2, the liquid crystal display 14
A warning message is automatically displayed indicating that there is a hardware problem. Therefore, even if the E2FROM9 is not inspected or many hardware abnormalities occur in a short period of time, the operator can be alerted to the problem before the hardware malfunctions. This has the advantage of being definitely preventable.

In the above embodiment, the printer 4 and the professional software disk device 1 are shown as peripheral devices that perform the retry function, but they may also be a display device, a \-F disk device, or the like. Further, in the above embodiment, the number of times of gluing try processing is stored in the E2FROM9, but it may be stored in a rewritable ROM other than RAMI O or the E2FROM.

Further, in the embodiment described above, a warning message is displayed on the liquid crystal display 14 when the number of times of memorization or trial processing reaches a predetermined value, but a warning sound may be emitted from a buzzer or the like. It goes without saying that various other modifications can be made without departing from the spirit of the invention.

[Effects of the Invention] As detailed above, according to the present invention, retry processing is performed due to a temporary abnormality in /X-ware during information communication processing with a printer or the like or information writing processing to a floppy disk or the like. It is possible to provide an information processing device in which it is possible to check by a simple inspection operation whether or not the hardware has failed, and to detect and prevent hardware failures in advance.

Further, it is possible to provide an information processing apparatus that can automatically issue a warning when a certain number of retry processes have been performed, and that can reliably prevent hardware failure.
