Abstract

PURPOSE:To perform automatically an abbreviated diagnosis just with input of a command to the menu of the 1st layer and with no complicated menu operation, by combining a menu selection system and a command input system for system diagnosis. CONSTITUTION:A diagnosis means (f) performs diagnoses automatically and in the prescribed order for the diagnosis items designated by a diagnosis item memory means (b). When the diagnosis items excepting for those abbreviated ones are designated in all hierarchies by a command input means (e), these designated items are diagnosed. In other words, the diagnoses are automatically carried out with setting done in an abbreviation mode in case the abbreviated diagnoses are designated. When no abbreviated diagnosis is designated, the diagnosis items which are interactively designated by the menus of each diagnosis hierarchy are carried out.

Description

Detailed Description of the Invention 3. Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a command input method for diagnosing a system such as a word processor.

(Prior art) In a system that combines a computer such as a word processor with many boards and external devices,
In order to check the operation of the system, the computer is caused to run a predetermined diagnostic program to discover failures.

The diagnostic program is a sequential arrangement of operation check items, and each check item (such as poor connections between each board device that makes up the system and malfunction of circuits within each device)
We will examine whether a predetermined output can be obtained for a predetermined input signal.

The results of this diagnosis are displayed on the CRT screen. The user proceeds with the diagnosis while looking at the contents displayed on the CRT screen. If an abnormality is found, an error message will be displayed.

(Problems to be Solved by the Invention) In diagnosis, methods for giving instructions on diagnostic items include a menu selection method and a command input method.

In the menu selection method, the user selects the required item from the menu items displayed on the screen and gives instructions.

This input method is easy to use, even for beginners, because the contents to be specified can be determined by looking at the menu display.

However, even if you get used to it, it requires complicated operations. On the other hand, in the command input method, no menu is displayed, and the user selects and inputs the command to be specified. This method is difficult for beginners to use, but once you get used to it, you can operate it quickly.

An object of the present invention is to provide an easy-to-operate input method that combines a menu selection method and a command input method in diagnosis.

(Means for Solving the Problems) The system diagnosis method according to the present invention (see FIG. 1) is a diagnosis method for diagnosing a system composed of a plurality of modules and external devices. means (a), and a diagnostic item that stores, for each diagnostic item in a certain upper hierarchy among diagnostic items forming a plurality of hierarchies, the diagnostic items in the lower hierarchy belonging to the diagnostic item and the presence or absence of an abbreviation setting for each diagnostic item. The storage means is a default setting means C for setting diagnostic items when an abbreviated diagnosis is specified in the diagnostic item storage means.
and a menu display means d for displaying on the screen display means a table of lower-order diagnosis items (including abbreviated diagnoses) to be specified for each diagnosis item, and designating a diagnosis item in the table displayed by the menu display means. When an abbreviated diagnosis is specified using the command input means e and the command input means, the diagnosis of the diagnosis item for which the abbreviation is specified in the diagnostic item storage means and the diagnosis item for which the abbreviated diagnosis is specified for the subordinate diagnosis item belonging thereto. and a diagnostic means f which automatically executes the following in a predetermined order, and when a diagnostic item other than the abbreviated diagnosis is specified in all layers by the command input means, executes the diagnosis of that diagnostic item. .

(Operation) When an abbreviated diagnosis is specified, the diagnosis is automatically executed according to the default settings.

If an abbreviated diagnosis is not specified, the diagnosis of the diagnostic item specified interactively from the menu in each diagnosis hierarchy is executed.

·now (Example) Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

(a) Structure of Word Processor FIG. 2 shows the appearance of a word processor according to an embodiment of the present invention.

The word processor uses a keyboard 5 which is an external input device.
00, a host computer 200 consisting of electronic parts such as a CPU, 10M, RAM, etc., and a power supply (see Fig. 3).
and a floppy disk drive 3, which is an external storage device.
01, 302, etc., and a display 1
00, and a daisy-wheel printer 400 which is an external output device.

Furthermore, each device will be described.

A main switch (not shown) and floppy disk drives 301 and 302, which are external storage devices, are arranged in the main body 300 to be directly operated by an operator.

The display 100 includes a brightness adjustment knob (not shown) and a Cr(T screen 102) that displays input from the keyboard 500, as items directly related to operator operations.

The keys arranged on the operation surface (see FIG. 2) of the keyboard 500, which is an external input device, include character keys 510., which are used to input characters such as alphanumeric characters as in a general typewriter. A function key 520 to which a special command is assigned when the word processor program is loaded, a cursor movement key 530 for moving the cursor on the CRT screen 102 when the word processor software is loaded, numbers, etc. There is a numeric keypad 540 for inputting.

Next, we will discuss the steps to actually create a document using a word processor.

When the power is off, the system disk containing the word processor program is inserted into the floppy disk drive 301, and the system disk containing the word processor program is inserted into the floppy disk drive 302.
In this case, the main switch of the main body 300 is turned on with the data disks for storing the contents of the created documents inserted. The host computer 200 built into the main body 300 reads the contents of the system disk inserted into the floppy disk drive 301. When the contents of the word processor program stored in the system disk are loaded, the CRT screen of the display 100 displays the space that can be printed by the printer 400 in a frame (not shown).
Also, a cursor is displayed at the left end of the first line where printing starts.

In this state, the character key 51 on the keyboard 500
When you press 0, the input character is displayed at the position indicated by the cursor.

Next, the schematic configuration of the host computer 200 and the input/output of signals between the data on the memory 202 and the CPU 204 will be explained using FIG.

The CPU 204 is a so-called microcomputer that performs arithmetic processing, and the registers, input/output ports, etc. and their functions are well known, so a description thereof will be omitted. FDC206 is a floppy disk drive (FDD A) 301
．． (FDD B) This is a floppy disk controller that controls input and output to 302. PRT
I/F2O3 is an input/output interface for signals to the PRT (printer) 400, and similarly, the CRT controller 210 is a human output interface to the CRT (display) 100, and is connected to the video memory 214. In addition, the keyboard interface (KB
I/F) 212 is an input interface with the keyboard (KB) 500. COM r/F216 is
It is an input/output interface with the outside, and also an RTC
21B is a lock indicating the current date and time. Also, SP
The K I/F 220 is an input/output interface with the speaker (SPK) 222. The speaker 222 is used to emit a warning sound.

First, when the main switch of the main unit 300 is turned on with the system disk inserted into the floppy disk drive 301 and the data disk inserted into the floppy disk drive 302, the CPU 204 loads the program stored in the ROM area of the RAM/ROM memory 202. The contents of the system disk are transferred to the RAM/ROM memory 202 through the floppy disk controller 206 according to the contents.
is stored in the RAM area. Input signals from the keyboard 500 are input to C through the keyboard interface 212.
Input to PU204. Next, the CPU 204 performs processing according to the contents of the screen editing routine storage section, and
CRT (display) 1 through controller 210
00 and displayed on the CRT screen 102. Input signals from the keyboard 500 are stored in RAM as a document memory.
/ is stored in the RAM of the ROM memory 202.

(b) Diagnosis and Menu Hierarchy In this embodiment, diagnosis items have a hierarchical structure as shown in FIG. For example, to the main menu, which is the top layer, the second layer A to 1 ((indicates the diagnosis item name in the block) belong), and the second layer diagnostic items (CRT
) belongs to A to F in the third hierarchy, and A to F in the fourth hierarchy belongs to the diagnosis item (VRAM) in the third hierarchy.

For each diagnostic item in the hierarchy above the lowest level, a table (menu) of lower diagnostic items belonging to that diagnostic item is displayed on the screen. Therefore, the menus form a hierarchical structure.

In FIG. 4, the diagnostic item Z in the second and lower layers does not mean the diagnostic item itself, but means that an abbreviated diagnosis (default diagnosis) is performed in that diagnostic layer. In the diagnosis menu, these items are displayed side by side with the diagnosis items of the same hierarchy on the left side, so they are also shown side by side in FIG. Second
In the hierarchical abbreviated diagnosis (Z), all system components (all diagnostic items) are diagnosed. In the abbreviated diagnosis (Z) of the third and fourth hierarchies, only the items that should be diagnosed during the preset abbreviated diagnosis are diagnosed.

Next, a specific example of the menu will be shown. FIG. 5 shows the main menu at the top level. In other words, CRT screen +0

It is stored as a structure array C0NFIG consisting of three elements: test, that is, the start address (number) of the diagnostic program. Table 1 shows the declaration of the structure array C0NFIC.

Table 1 Test structure array 5truct C0NF IG (int 5tatus; Default test instruction flag char * menusg; Menu message int (mtestX); Test routine address); An 8-dimensional structure array is shown. Here, the name of the structure is config and its dimension is 8. The default test instruction flag (status) is SET or RESET. SET means that the diagnosis is to be performed during the abbreviated diagnosis, and RESET means that the diagnosis is not performed. Menu messages are characters between quotation marks,
Used when displaying the character on the menu. The start address is used to store the start address of the diagnostic program for the diagnostic item in the program pointer when executing the diagnosis. For example, config[l] is the diagnostic item CP

); (d) Menu selection method and command input method in diagnosis Next, a method for diagnosing a word processor.

The order will be explained.

With the power off, a disk containing a diagnostic program is inserted into the floppy disk drive 301, and the main switch of the main body 300 is turned on. The host computer 200 built into the main body 300 reads the contents of the disk inserted in the floppy disk drive 301. When the contents of the program stored on the disk are loaded, the display! The CRT screen 102 of No. 00 displays a main menu as shown in FIG.

In the first method (menu selection method), diagnosis can be performed by sequentially selecting diagnostic items from the menu of each diagnosis hierarchy, as in the past. For example, display 10
0 VRAM with test pattern 55H (odd bit = 1
) and 0AAH (even bit = 1), first select rdJ (CRT test) on the main menu (Figure 5), then select "b" on the CRT mail (Figure 6).
” (VRAM test), then select rcJ (55H) and rdJ in the VRAM data pattern menu (Figure 7).
(OAAH) should be selected. As shown in FIG. 8, the diagnosis results are displayed in a diagnosis result display field 120 on the CRT screen 102. As shown in FIG.

In this example, no abnormality is detected and rPAssEDJ is displayed.

In the method described above, key input is required for each menu level. On the other hand, the feature of this embodiment is that the main menu
An abbreviated diagnosis item, Default test, is provided in the lower-level menus, and by using this, important diagnoses can be made just by inputting commands (Roman numerals) (command input method). If you specify "*" instead of this number, you can specify an infinite number of times.

For example, the Defaultt of the CRT test (Figure 6)
est (abbreviated diagnosis) items [B, C, D, VR
If [C, D] are registered in advance as the DefauHtest (abbreviated diagnosis) (Fig. 7) of the AM data pattern, just by inputting rdlJ (CRT test once) on the main menu (Fig. 5), ( (see FIG. 9), the abbreviated diagnoses in the menus in the following hierarchy are automatically executed one after another. 1st
Figure O shows an example of the diagnosis results. In this example, VR
No abnormality was detected in the test pattern of AM odd bits on and even bits on, PCW mode, and IBM mode.

Similarly, if you enter "d3" in the main menu (the first
1), the above abbreviated diagnosis is repeatedly executed three times (see FIG. 12).

Furthermore, if you enter "d*" in the main menu (the first
3), the above abbreviated diagnosis is repeatedly executed until it is interrupted by inputting the ESC key. In the example shown in Figure 14, 2
Interruption is instructed during the first diagnosis.

Furthermore, when rzlJ (all tests once) is entered in the main menu (FIG. 15), abbreviated diagnosis is automatically executed for all components of the system (FIG. 16). In this example, errors were found in FDD A and F'DD B.

The explanation will be omitted, or even in the menus below the second layer.
Just by entering zJ+number, an abbreviated diagnosis will be executed for that component.

(f) Diagnostic program <f-1> Main flow The diagnosis program will be explained below.

FIG. 17 shows the main flow of the diagnostic program. First, initialization is performed (step PI, steps will be omitted hereinafter).

Next, the presence or absence of an error in the diagnosis result by the diagnosis program stored in the ROM of the memory 202 is checked (P2
, see Figure 18).

Next, the hardware to be diagnosed is displayed and reconfigured (see P3, Figure 20).

Next, display the omitted diagnostic items and reset them (P4, 2nd
(See Figure 4).

Next, a command is selected using the test structure array config as an argument, and diagnosis is performed (see P5, FIG. 25). Diagnosis continues until abort or exit (ESC) is indicated.

<f-2> ROM diagnosis FIG. 18 shows the flow of ROM diagnosis (P2).

First, it is determined whether or not there is an error as a result of executing a diagnostic program in the ROM of the system (pH).

If there is no error, return immediately.

If there is an error, it is displayed on the diagnostic result display 11!1120 of the display (CRT) 100 (P12).

FIG. 19 shows an example of the CRT screen. In this example,
Two errors were found, and for each item, the code number, error details, and elements to be replaced (board, cable, external device, etc.) are displayed.

Next, it is determined whether there is an error in the keyboard (PI3). If not, then configure the hardware component in which the error occurred to be omitted from diagnostics (PI
4). Specifically, the test structure array config (
RE the flag 5 status with error in Table 1)
Make it SET.

If it is determined in step P13 that there is a keyboard error, key input is not possible, so the keyboard test (PI5) is repeated and the keyboard 500 is repaired. Then, perform the diagnosis again from the beginning.

<f-3> Hardware configuration display/resetting Figure 20 shows
The flow of hardware configuration display/resetting (P3) is shown. First, the nodeware components to be diagnosed are displayed on the system configuration 111130 of the CRT screen 102 (P2
O). Specifically, hardware components with flag 5tatus=SET in the test structure array conrig (Table 1) are displayed.

FIG. 21 shows an example of the display. On the "system configuration side" 30 of the CRT screen 102, the hardware component with the error is deleted and only five components are displayed. Note that the error display (step P12) has been moved to the bottom of the screen.

Next, an instruction is given as to whether or not the display on the CR7 screen +02 is correct (step P2+). If correct, return immediately.

In step P21, if the display is incorrect, all hardware elements are
30 (P22). Next, use the keyboard 50 to input the alphabetic characters displayed before each component name in this display.
If you input 0 upstream (P23), the flag 5ta for that item will be set.
tus is reset (P24), the process returns to step P20, and the CRT image is displayed on screen 1 and 2 again. In addition, if you key in Z at P23, the flag 5tatus of all hardware in the config will be set to SET, and the next display (P
2O), all hardware components are displayed, as shown in FIG.

<r-4> Omitted diagnosis item/resetting FIG. 24 shows the flow of omitted diagnosis item display/resetting (P4). First, the diagnostic items (st
atus = S ET ) is displayed on the CRT screen 103 (P2O). Then, an instruction is given as to whether or not this diagnostic item is acceptable (P31). If you indicate that it is ok, please return it immediately. If no, all diagnostic items are displayed on the CRT screen 102 (P32). Then, when the omitted diagnostic items are input from the keyboard 500 (P33
), the flag 5tatus of the omitted diagnosis item is set to SET (P311).

Then, the process returns to P2O and is displayed on the CRT screen 102.

<f-5> Command selection FIG. 25 shows the flow of command selection (P5) in diagnosis.

First, display the menu (see Figures 5 to 7) on page 2.
O) Input one line of command and store it at the beginning of the line buffer (P41). If there is no input (P42), return immediately. If there is an input, the character pointer is set to the beginning of the line buffer (P43).

Next, it is determined whether there are any characters (P44).

If it is not a character, return. If it is a character, skip the blank character (P45) and set the flag to N0NINTER.
(Non-interactive mode) P46), capitalize the character pointed to by the character pointer and input it to index C P47
), the character pointer is increased by one (P48).

Next, it is determined whether the index C is Z (P
2O). If it is Z, then the initial setting of the number of times of diagnosis is performed (P51). Next, it is determined whether the set number of times is infinite (*, that is, the maximum value 32767, hereinafter referred to as MAX) (P52).

If not, set counter i to 1 (P53),
Abbreviated diagnosis is performed (PS5) until the set number of times is counted (P54), and i is incremented by one (P56).

If the ESC key is pressed during the abbreviated diagnosis (P55),
The diagnosis is interrupted and the process returns to step P44.

If it is determined in step P52 that the set number of times is infinite, then i is set to 1 (P57), an abbreviated diagnosis is performed (P58), and i is incremented by 1 (P59), and step P58 is again performed. Return to and repeat the abbreviated diagnosis.

If the ESC key is pressed during the abbreviated diagnosis (P58), the diagnosis is interrupted and the process returns to step P44.

If it is determined in step P50 that index C is not Z, then a search is made to see if index C corresponds to a diagnostic item (P2O). If not, the process returns because diagnosis cannot be made. If it is compatible, next perform the initial settings for the number of scans (P61
). Next, the set number of times is infinite (*), that is,
Determine whether it is the maximum value (32767) (P62
). If not, after setting i=I (P63), single diagnosis is performed (P65) until the set number of times count is reached (P64), and i is incremented by one (P66). If the ESC key is pressed during single diagnosis (P65), the diagnosis is interrupted and the process returns to step P44.

If it is determined in step P62 that the set number of times is infinite, then i is set to 1 (P67), a single diagnosis is performed (P68), and i is incremented by 1 (P69), and step P68 is performed again. Go back and repeat the single diagnosis.

If the ESC key is pressed during single diagnosis (P68), the diagnosis is interrupted and the process returns to step P44.

If a character is found again in step P44, a diagnosis corresponding to that character is performed. Therefore, multiple diagnostic items (designated 10 times) can be performed simultaneously.

Note that this command selection routine uses the test structure array name as an argument not only from step P5 but also from step P121 and step P133, which will be described later.
then cant ig, crtte in step P12I
st, step P133 is configured so that it can be called recursively using ramdata as an argument.

FIG. 26 shows the flow of menu display (P2O).

First, index C (corresponding to the uppercase Roman letter at the far left of the menu) is set to °A'' (P2O).

Next, it is determined whether the loop has been repeated for the number of test structure arrays as arguments (P71). If not, then the argument is co
equal to r+4ig and flag 5tatus is RESE
It is determined whether it is T (P72). in that case,
Return to step P71. If not, index C and the message of the corresponding structure (for example, the quotation mark part of the structure array in Table 1) are displayed on the CRT screen 102 (7).
No 1-knee m11 or, = Display 1 line (P73
). The index C is increased by one, C is changed to alphabetical type (P74), and the process returns to step P71.

If the loop is completed (P71), then r'Z'J is displayed as the index C, and the abbreviated diagnosis items are displayed (P75). And then return.

Note that the number of loops, message content, etc. differ depending on the menu hierarchy and items.

FIG. 27 shows the flow of the number of scans (P51.P61). Skip blank characters and get characters (P2O)
. Next, determine whether the character is * (infinite times) (
P81). If so, count (number of scans)
Let be M A X (i Otake) (P86).

Then, since the count is not 0 (P87), the player continues to turn.

In step P81, if the character is not *, C0un
is set to 0 (P82), and then it is determined whether the character is a number (P83). If it is a number, cou
Convert and set nt to tox count Juji-0' (IO base code) (P84), and read the next character (P85).

If it is determined in step P83 that the character is not a number,
Next, it is determined whether count is O (P8
7). If it is not 0, it means that count is specified, and the process returns immediately. In this case, the flag is NON
I NTER (non-interactive mode) and executes abbreviated diagnosis the set count number of times.

In step P87, if count is 0, then
Since unt is not specified, next set the flag to INTER(
Interactive mode) and set the count to 1 P8g),
Return.

Therefore, both commands "d" and "dI" are c
They are the same in that ount is I (diagnosis is performed once), but in the former case, a CRT test submenu is activated, and in the latter case, an abbreviated CRT diagnosis is automatically executed.

FIG. 28 is a flowchart of execution of the abbreviated diagnosis (Pb0, P58). First, display the count (P2O, 30th
(see figure). Next, it is determined whether the loop has been repeated for the test structure array of the argument (P91).

If so, return.

If not, then it is determined whether the flag 5tatus is SE'T (P92). If not, the process returns to step P91. If so, run the abbreviated diagnostics (

If the ESC key is pressed during step 6), return.

(Effects of the Invention) The menu selection method required complicated operations even after getting used to it, but with the present invention, important diagnoses can be made just by inputting commands. The command input method was difficult for beginners to use, but
In the present invention, it is easy to use only one menu. Abbreviated diagnosis can be performed automatically by simply inputting commands to the first layer menu without complicated menu operations. By simply inputting the digits °Z° into the first layer menu, abbreviated diagnosis can be performed automatically for all modules. Nth layer (
N22) menu, you can perform an abbreviated diagnosis for that module by simply entering the ten digits °Z°.

It is possible to specify the number of times of diagnosis (including an infinite number of times).

Multiple diagnostic items can be specified ten times at once.
