Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a system for executing #cutting programs in a main body device controlled by a microprogram system, and in particular, 1IiIjI! By storing the R-Grogkum in the maintenance panel instead of permanently residing it in the combination unit for controlling the main unit, the space required for the combination unit for controlling the main unit can be reduced and the nine-step program can be implemented. Execution method Wc
Do 1I.

Regarding diagnosis using microprograms, various 7J methods have been proposed and implemented up to now.

As an example of this, a control storage (hereinafter referred to as C8) for storing micrologs,
Rewrite WJ function control storage (
(hereinafter referred to as WCS).

When diagnosis is performed using this configuration, tlK
In this method, a diagnostic microprogram was loaded into the WCS from an appropriate secondary storage device, and the diagnosis was performed using the microprogram.

However, in this method, the C8 that stores the microglots must be made up of a feeder M.

Therefore, compared to the case of BDMK), it lacked stability in the medium, and had disadvantages such as evaporation of pugkum and 0 pip Y drop when loaded.

Another conventional example is a system in which a diagnostic MyTatsu blog 2 is resident in the C8Q and executed as needed.

However, in the normal case, the memory space for C8 is not wide, and is at most IK-4Kli degrees.

Therefore, most of the time during the Mekamori 9 is used by Shamitomi's commands.

On the other hand, a diagnostic microphone stomach glow/2 module usually requires a very large memory 9 threshold, so even if the necessary microprograms are stored in a normal Cs, it will only be possible to make a very limited diagnosis. It punishes the shortcomings of being only self-sufficient.

Furthermore, it is also conceivable to make the memory space for the C8 sufficiently large so that all necessary diagnostic micrologs can be stored. However, in this case, the company would normally have to equip the Mitalob, which is rarely used, with a large capacity ROM for the two people,9 which would be uneconomical and lead to a 6% increase in costs. produce defects.

The present invention corrects the drawbacks of the conventional O as described above, and makes it possible to eliminate the need for a diagnostic microgram without increasing the memory space for the C8 or making the diagnostic microprogram resident. At one point, Mori calls up the miterlog tsum and offers O'C his own diagnostic program execution method.

In order to achieve the above object, the present invention provides a ROM K% in a maintenance device (maintenance panel) equipped with a changeover switch, an indicator lamp, an operation switch, a start switch, etc.
You can memorize the diagnostic microlog tsum and connect it to the main unit when diagnosing a fault. It is configured to execute Ikukangu4gutsumu.

Furthermore, in the present invention, the diagnostic microprogram is divided into several parts according to the types of parts targeted for failure diagnosis, and the KPII and C8 addresses are allocated for each divided unit, so that when executing the program, the selection switch is pressed. By switching, the desired one is selected and connected to the main body.

In general, the maintenance of peripheral devices such as microprogram controlled combination terminals or intelligent terminals is commonly used. In addition to the usual tools, people often have unique Buddha 41F possible tools that are suitable for their systems.

A device called a maintenance spring is commonly used as the above-mentioned unique jig.

The maintenance panel has two displays and switches attached to it, allowing maintenance personnel to connect it to the system and manually operate the switches to view the internal information of the target system. I sleep because I can worship my state.

Honji @ focuses on such a maintenance panel (maintenance device) and skillfully uses it for 111.

An embodiment of the present invention will be described in the afternoon with reference to the drawings.

FIG. 1 is an external perspective view of a protective panel suitable for an embodiment of the present invention, and FIG. 2 is a schematic diagram showing a tatami part of its internal structure.

In these 0IlI, 1 maintenance panel, 2 display 2
Details of the pump, 3 is the operation switch group, 4 is the connection cable, S
1 is a cable connector, 8 is a changeover switch, 9 is a start switch, and 21-1 to 2 are provided in the maintenance panel 1 and are CS (:1) in the maintenance panel that stores a microgram for failure diagnosis. )) 27 is an enable fin, and 28 is a start signal. The maintenance panel shown in Fig. 2 is connected to the control combination 11 to indicate leprosy.The same 〇 symbols as in Fig. 1.2 in the figure are the same. It's raining on parts.

In FIG. 3, 6 is a combinator part for controlling the main body, 22
C8, 28 in the Hiro system is a pipe twin register, 26
is a sequencer.

In particular, as is clear from the 3rd al, the maintenance panel 1 and the main body trace O control; ). 9. The maintenance panel 1 is provided with a changeover switch 8 and a start switch 9.

In FIG. 3, the microphone program which performs the normal system OIm 111 - that is, the microphone part Durham Co., Ltd. for controlling the normal operation of the main body, and C8 (for example, ROM) 22 of the main body control copier section 6. Stored.

As an engineer familiar with Todoroki's techniques 11 can easily understand, the read data of the C822 in the system output to the output data bus 23 is transferred to the pipe twin register 25, stored, and executed by the microprogram. used to execute.

At the same time, a portion of the read data is supplied to the sequencer 926 for the next! KI to decide the execution address of Ikroprog 2fu! used. That is, the address signal line which is the output of the sequencer 26 and the address bus 24 are used as the address input to the CS 220 in the system.

Here, the address 9 of microprogram 2 is Example Eva, No. 41C1! Assuming that KOGO$ and FFFtf04y are used, in actual practice, the first 2KW, that is, 7FF1 from OOO, will be converted into BJoM and stored as a gross data that performs the normal system 0 function. And allO! In other words, in the KW-800 FFF trench, it is left open as an overlay area for the diagnostic program.

The first sal is C821-1゜2 in the toe joint maintenance bar 4h.

FIG. 2 is a schematic diagram showing the connections of the CBt2 and the CBt2 in the system. C821-1 to C821-2 in the maintenance panel are connected in parallel by data bus 2B and address bus 24, respectively.

When you run a Google tsum that uses a microphone for blocking, the first thing you'll see is one of the several Google tsums that share the address.
The changeover switch 8 determines which one to execute. For this purpose, each enable twin (selection group) 27 of the changeover switch 8 is connected to a CB (ROM) O chip enable terminal in the maintenance panel that stores the OS*O microprogram.

Then, the selector switch 8 selects ? C8 (in the maintenance panel that is supplied with the F-build enable signal)
ROM) data, the specified address is SOO~FFF
(The hexadecimal table shows the range of 2 false to 4 false), the data bus 23 is pressed.

On the other hand, if the microprogram 2 that controls the functions of the normal system (main unit) is in progress, the system control is not executed, the start switch 90 in the maintenance panel 1 is in a standby state, or an idle state. The on/off state can be determined.

Then, if the judgment (1) is negative and the start switch 9 is on, the program jumps to the start address of the diagnostic microprogram that is uniquely determined in advance and executes the desired diagnosis.

As is clear from the above description, according to the present invention, when a maintenance person wants to run a diagnostic program, he connects the maintenance panel l to the system (
By connecting to the converter section 6 of the main unit), selecting the selector switch 8 to match the type of diagnostic microprogram to be executed, and then pressing the start switch 9, the desired diagnostic microprogram can be executed. This makes it faster to carry out the process properly.

That is, according to the present invention, the diagnostic microprogram is stored in a maintenance panel carried by a maintenance person, and is not permanently resident in the system (main unit) 0, so it is not stored in the system. There is no need to increase the OCSO memory space, and a 4HJL system can be constructed economically.

In addition, in the practical example shown above, of the CSO address space (total 4ff), -m<o~2KW) is set as the 9th program area that controls the normal system, and l
It is also possible to use the entire address space as an overlay area by setting the area (jlKW to 4KW) as the overlay area of the diagnostic PID ram.

This rounding can be accomplished by inverting the enable signal 4 in the main body 6 with an inverter 211 shown by a dotted line in FIG. 5 and supplying it to the changeover switch 8.
