Abstract

PURPOSE:To easily investigate the cause of an abnormality at the time of the generation of an abnormal state by recording key depression information and error information when depressing a key as an operating log. CONSTITUTION:When same key on a keyboard 2 is depressed, an MPU9 starts the preparation of a key log through a key control part 5. The MPU9 requests the key code of the key depressed against the key control part 5, and stores the transferred key code in the internal register. Then, it requests a display control part 4 the screen code of the screen which has been displayed when the key is depressed, and the transferred screen code is stored in the internal register. Then, the MPU9 combines the key code stored in the internal register and the error code written in the RAM8 and prepares a key log to be written in the RAM8. In this case, the error code is rewritten to the update state. The set constant amount of key log is stored in the RAM8 in advance, and the excess one is discorded in the logged order.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a key operation recording method for recording keyboard key operations and error information caused thereby.

0002

[Background Art] Many of the latest devices have an input section with a display and a keyboard.If the device becomes abnormal, if the operator recognizes the operation error, he or she can respond to the abnormal condition. Although it is easy to do so, the operator is often unaware of the error even if it is an operational error.

0003

[Problem to be solved by the invention] In such cases, it is very difficult to distinguish whether there is an operational error or a bug (error in the program) in the device, and it may take time and effort to respond to the abnormal situation. many. Furthermore, in the case of a wrong operation or a misremembering of an operation, it is not only difficult to recognize it, but also very difficult to make the operator realize that it was an operational error. Furthermore, if there is a bug in the device, it is necessary to reproduce the abnormal condition to determine the cause and eliminate it. However, an abnormal state often occurs only when a certain specific operation is performed, and in such cases, it is extremely difficult to reproduce the abnormal state and it is also difficult to determine the cause.

The present invention has been made in view of the above-mentioned problems, and provides a key operation recording method that records key operations and related information and facilitates investigation of the cause when an abnormal state occurs. The purpose is to

[0005]

[Means for solving the problem] In order to achieve the above object, in a key operation recording method for a device that inputs information from a keyboard while referring to a display, pressed key information and error information when a key is pressed are recorded as an operation history. I'll do what I do.

[0006] Also, screen information at the time of key presses is added as the operation history.

[0007]

[Operation] With the above configuration, when an error occurs, the error information and a record of which key was pressed that caused the error can be obtained, so the cause of the error can be understood and measures to prevent the error can be devised. becomes easier.

[0008] Also, by adding the screen information when a key is pressed as a record, if the screen information differs even if the same key is pressed, a different error may occur, so it is possible to easily analyze errors in such cases. become. Furthermore, even if the key is the same in terms of hardware, if it is assigned a different meaning on each screen, the screen information can be specified, making it possible to accurately understand the meaning of the key.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of this embodiment. 1 is a display section; 2 is a keyboard; the operator presses a key corresponding to the content displayed on the display section 1; 3 prints out the output in the printing section. 4 is a display control unit that controls the display unit 1; 5 is a key control unit that controls the keyboard 2; 6 is a print control unit that controls the print unit 3; 7 is a ROM that stores programs and data; 8 is a RAM; 9 is an MPU that controls the entire system.

Next, the operation will be explained. keyboard 1
When any key is pressed, the key control unit 4
U9 starts creating a keylog. The MPU 9 requests the key code of the pressed key from the key control unit 5, and stores the key code sent from the key control unit 5 in an internal register. Next, the screen code of the screen that was being displayed when the key was pressed is requested from the display control section 4, and the screen code sent from the display control section 4 is stored in an internal register. Next, MPU9
A key log is created by combining the key code stored in the internal register, the screen code, and the error code written in the RAM 8, and this key log is written in the RAM 8. The error code is always updated to the latest version. A predetermined amount of key logs is stored in the RAM 8, and the oldest ones are discarded in excess of this amount. The stored key log is printed out by the printing section 3 in response to a request.

FIG. 2 shows an example of printing a key log. In the figure, from the left, the key code, screen code (DISPCOD)
E), the error code is written and the latest operation is displayed at the top. The status from 11 steps ago is recorded, and the error code is 00 until 4 steps ago, and no error has occurred. However, in step 3, the screen code is "2D"
When I pressed the key "01", an error "04" occurred. Press the key “1E” on the automatically switched display screen “09” to switch to the menu screen “0A”,
A key log output request is made using the key "1E", and upon receiving this output request, the printing section 3 outputs a key log list. The key “1E” pressed in steps 1 and 2 is physically the same key, but the screens are different, so it is clearly recorded that the press had a completely different meaning, so error analysis useful for. Note that although the printing example shows an example of 11 steps, in this embodiment, a key log of 128 steps is left.

0012

As is clear from the above description, the present invention records key press information and error information, and is therefore useful for investigating the cause of errors and taking measures to prevent errors. Additionally, by adding screen information, it becomes easier to investigate the cause of errors and establish preventive measures.
