Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention approximates a series of procedures such as collecting, diagnosing, and analyzing fault data necessary for fault countermeasures to the expression of a fault countermeasure manual. Diagnosed information processing that has a self-diagnosis function is stored in a troubleshooting procedure recording unit (for example, a floppy disk) so that it can be displayed on a display unit, such as an electronic luminescence display (hereinafter abbreviated as an EL display panel), in a format in which When a failure occurs by connecting the device with a cable, the self-diagnosis function of the device to be diagnosed is activated to automatically execute part of the troubleshooting procedure, and the troubleshooting procedure is sequentially executed from the troubleshooting procedure recording section. The present invention relates to a portable fault diagnostic device which is easy to operate and standardized, which is read out and displayed on a display section, and which requests an operator, that is, a maintenance engineer, to input necessary instructions and procedure data by key.

[Prior art] Various portable fault diagnostic devices have been developed in the past, but most of them were primarily intended for remote diagnosis, and the know-how for troubleshooting was not built into the diagnostic device itself, but was centrally located at a maintenance center. In addition, the diagnostic function is realized by the hardware and programs of the diagnostic equipment itself, and it is necessary to newly maintain the equipment to be diagnosed that has not been maintained before. In this case, the development and maintenance of troubleshooting procedures requires knowledge of the diagnostic equipment hardware and programming language, which requires a large amount of development man-hours.
Furthermore, there were various problems, such as the fact that the display was not usually in Japanese mixed with kanji.

[Problem that the invention seeks to solve]

The present invention solves the problems associated with the conventional technology described above, and provides relatively simple and standard troubleshooting procedures (compiled like a manual) to be used in a fault diagnosis device for a new device model to be diagnosed. The purpose of the present invention is to provide a portable fault diagnosis device that can be created by a method and can be used even by inexperienced character retention engineers. Note that all the information processing devices to be diagnosed that are the object of the present invention have a built-in self-diagnosis function.

[Steps to resolve the problem]

In order to achieve the above object, in the present invention,
Execution control means, diagnosed information processing device control means, procedure registration and update control means, fault countermeasure procedure recording section, fault data/diagnosis data recording section, display section,
It is equipped with a key input section (here, "section" means hardware, and "means" is operated by a program), and a series of troubleshooting procedures such as collecting, diagnosing, and analyzing fault data are created for each device to be diagnosed. Register the procedure so that it can be displayed on the display unit in correspondence with each page of the troubleshooting procedure manual, store it in the troubleshooting procedure recording section via the update control means, and connect it to the device to be diagnosed using a cable suitable for the device being diagnosed. When a fault occurs, under the command of the execution control means, the self-diagnosis function of the device to be diagnosed is activated to read the fault data/diagnosis data into its recording section and automatically execute a part of the damage countermeasure procedure, and The troubleshooting procedures are sequentially read out from the troubleshooting procedure recording section and displayed on the display section, and the operator of the diagnostic device, ie, the maintenance engineer, is asked to respond to key inputs of necessary instructions and procedure data.

If a fault diagnosis manual exists for the information processing device to be diagnosed, and if you want to display a certain page of the manual or content almost similar to it on the display unit, it is of course necessary to create a program for this purpose. . Further, a program is also necessary when a maintenance engineer responds by key-inputting selected instructions or procedure data in response to such a display. However, all of these programs are of a relatively small number of standard types, and once created, they can be used repeatedly by simply changing the parameters. Even if the program itself is quite complex, if a small number of programs can be used repeatedly, it will not be a burden to the operator. Also, if you do this,
The operator's knowledge of the hardware/software of the diagnostic equipment itself is not required, and even when starting maintenance for a new model of equipment to be diagnosed, the contents of the troubleshooting procedures (fault diagnosis manual) to be stored in the troubleshooting procedure recording section are not required. ) can be created using simple standard techniques. Note that it is convenient to use a floppy disk (hereinafter abbreviated as FD) for each model of the device to be diagnosed as the troubleshooting procedure recording unit. Changing the model of the target device to be diagnosed can be easily handled by replacing the FD, which is the troubleshooting procedure recording section. Since it has a key input section, the contents stored in the troubleshooting procedure recording section can be easily registered and updated using the editor, which is a standard program, in the diagnostic device itself or, if necessary, on the go.

Note that the device of the present invention is connected to the device to be diagnosed using the most suitable cable according to the specifications of the device to be diagnosed.
This reduces the cost of the device to be diagnosed and ensures performance.

Furthermore, it would be convenient if instructions to the operator were displayed in Japanese mixed with kanji.

In the case shown in Fig. 1c, there are two judgment points on one page of the manual, so the EL display panel displays the information on two screens. In contrast, in FIG. 1d, both are the same. It is extremely easy to create input stickers from a manual in this way.

The CPU 12 is, for example, a 16-bit microcomputer, the ROM 13 has a program written therein for managing the hardware and software of the diagnostic device 1, and the RAM 14 has a management program executed from the FD 11 when the diagnostic device 1 is powered on. Control programs, procedure registration update control, and diagnostic device control programs are read and stored.
