Abstract

PURPOSE:To simplify constitution by using a display equipment and a warning equipment prepared ordinarily for a warning at the time of starting an operation and deciding and displaying whether or not the condition of the operation start of a computer is normal. CONSTITUTION:A computer 1 builds in a CPU 2, a memory, etc., and an FDD (Floppy Disk Driver) device 4 is connected by a DMA (Direct Memory Access) bus 7 and an I/O (In/Out) bus 8 from the CPU 2. The read initial program is stored into a memory 3 once, read into the CPU 2 and the initial program first executes the self-diagnosis of the conditions. According to whether the result is normal or abnormal, the displaying lighting-up of a prescribed action specified beforehand is executed and an abnormality displayed to a worker by the action. Thus, a special displaying device may not be added and the device can be simplified.

Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention provides a system for displaying the operating status of a computer that is equipped with an indicator light other than for indicating an abnormality and that starts operating when the power is turned on. The present invention relates to a computer equipped with a computer and a recording medium recording control signals for performing the computer.

(Prior Art) Recently, automatic devices incorporating microcomputers have been actively developed. These devices often perform automatic failure diagnosis or self-diagnose the device configuration. In order to display this result, if there is a failure or reading abnormality, it may be displayed on a display device, or a separately provided warning light for indicating an abnormality may be turned on. - Within the membrane, this information is usually displayed on a display device.

(Problems to be Solved by the Invention) However, in order to display the above-mentioned abnormality at the start of operation, a display device is required, or a warning light or the like must be separately provided for abnormality display. However, such display devices and warning lights for indicating abnormalities are expensive, and depending on the purpose of the computer, many computers are simple and do not have a complicated display from the beginning.

For example, in a device that controls machinery, an automatic sequence is normally activated when the power is turned on, so that no unnecessary display is performed. Furthermore, in many cases, computers usually start operating normally, so it would be wasteful to add a special display device in anticipation of an abnormal situation.

The object of the present invention is to provide a method, a computer, and a recording medium for displaying abnormalities and start-of-operation states of the computer without installing a new display device in a computer intended for such simple use.

[Structure of the Invention] (Means for Solving the Problems) In a method for displaying a start-of-operation state used in a computer that is equipped with an indicator light other than for indicating an abnormality and that starts reading an initial program into a recording device at the same time as the power is turned on. , comprises an initial program reading means for reading an initial program from a recording device when the operation starts, and an arithmetic means for performing calculations based on the initial program reading means, and performs self-diagnosis according to a self-diagnosis program of the initial program read from the initial program reading means. Provided is an operation start state display method that causes the indicator light to perform a predetermined operation as a result, a computer for realizing this, and a recording medium on which an initial program for realizing this is recorded. do.

(Operation) When a computer and a recording medium using the above-described method are used, reading of an initial program is started as soon as the power is turned on. The initial program read in this way is temporarily stored in the memory and read into the CPU. This loaded initial program first performs a self-diagnosis of the configuration. Depending on whether the result is normal or abnormal, a display for a predetermined operation is lit. These operations are recorded in advance in a recording mechanism within the computer, or as part of the initial program flow. When such an operation is performed, an abnormality is displayed to the operator.

(Embodiment) FIG. 1 is a perspective view of an embodiment of a computer (1) using the method of the present invention, and FIG. 2 shows a connection configuration of the computer (1). Further, the configuration of this embodiment is for controlling a mechanical device (not shown). The computer (1) has a CPU (2), memory (
3), etc., each has a built-in DMA (Direct Memory Access) from the CPU (2).
ss) bus (7), I 10 (In10ut) bus (
8) by F D D (Floppy Disc
Drlver> Device (4) is connected.

The operation of this embodiment at the time of power-on and start of operation will be explained using the flowchart of FIG. 3. Insert the floppy disk (6) into the FDD device (4) and turn on the power.
An initial program that performs self-diagnosis is read from the floppy disk. . This reading result is stored in the memory (3), and the computer (1) is operated according to this initial program.
A self-diagnosis is performed, and the memory (3) is checked and the status of the input/output equipment is diagnosed. If this diagnosis result is abnormal, the computer (1) cannot be put into normal operation. If it is found to be normal during the self-diagnosis, the function is stopped for one second and 32 KB (kilobytes) are read from a predetermined sector by the FDD device (4).

The function is further stopped for 1 second, and 32 KB is read from a predetermined sector by the FDD device (4) again, and this is repeated three times in total. 32KB from the specified sector from the FDD device (4)
(Kilobytes) By reading, the access lamp (5) of the FDD device (4) lights up for about 1 second. As a result, the light turns on for 1 second and turns off for 1 second, which is repeated three times to notify the operator that the computer (1) has been successfully started.In other words, the operator can start operation and access the computer for a while. Monitor the lamp (5), and if the access lamp (5) does not light up within the specified time, use the calculator (1).
) and stop its operation.

When it is normal like this, turn the access lamp (5) to 3.
Flashing the light twice means reading 32KB from the FDD device (4), so the floppy disk (6) inserted into the FDD device (4), the initial program loaded on this floppy disk (6), and the O8
It is also very effective because it can also be used to diagnose.

Note that the access lamp (5) also lights up when the initial program is read from the floppy disk (6), but this is clearly different from the flashing during the above-mentioned abnormality. The operator can determine whether the device is normal or abnormal by simply observing the access lamp (5) for a while.

In addition, in the above embodiment, the access lamp (
5) is lit and blinked three times, but the judgment in the flowchart shown in Fig. 3 may be switched between normal and abnormal times, and the access lamp (5) may be lit and blinked three times when there is an abnormality. . However, in this case, only the self-diagnosis of the computer (1) will be performed.

In addition, in the above embodiment, the access lamp (5) of the FDD device (4) is turned on for 1 second and turned off for 1 second, which is repeated three times, but this is of course an example, and the blinking interval, blinking The number of times may be any arbitrary number that calls the operator's attention. Furthermore, the present invention is not limited to FDD devices, but H
It may be used in a DD (Hard Driver) device or a memory card reader.

Further, the present invention is not limited to access lamps of FDD devices or HDD devices, and may be, for example, power lamps or other indicator lights. Furthermore, although a floppy disk is used as the recording medium in this embodiment, it may be any recording medium such as a memory card, ROM cassette, or recording tape.

[Effects of the Invention] As described above, the present invention allows the normally equipped display device and warning device to be used for warning at the start of operation, without adding six separate display devices to the computer, It is possible to determine and display whether or not the status is normal.
