Description

  The present invention relates to an information terminal.

When the information terminal executes the processing instruction, a malfunction such as reboot or freeze may occur in the operation of the information terminal. In order to analyze the cause of this failure, it is necessary to investigate which operation was performed at what timing. Hereinafter, this operation record and operation timing investigation record is referred to as operation history information. The test that is performed by reading the operation history information and reproducing up to the location where the failure occurs is effective in identifying the location where the failure occurred and the cause of the failure. In view of this, there has been proposed a test apparatus that stores operation history information during operation of a device and executes operation contents according to operation timing based on the stored operation history information during testing (see, for example, Patent Document 1).
JP-A-6-70009

  The invention described in Patent Document 1 is a method of performing a test by connecting an operation test device to a device to be tested. Then, the operation test device transmits a command to the test target device, and causes the test target device to execute processing. At this time, the processing procedure, processing timing, and parameters at the time of the operation test are stored in advance in the operation test equipment. At the time of retesting, the operation test device storing the processing procedure and the like is connected to the test target device, and a test execution instruction is output. Then, the operation test device transmits the same processing instruction to the test target device at the same timing according to the stored processing procedure, and reproduces the previous test.

  However, in the invention disclosed in Patent Document 1, since the processing procedure at the time of the operation test is stored in the storage unit of the operation test device, the processing procedure and the processing timing at the time of occurrence of a failure that occurred in a product on the market are stored. Because they are not intended, they cannot be analyzed.

  Therefore, an object of the present invention is to provide an information terminal capable of storing operation procedures and operation timings when operated by a user, and capable of performing failure analysis and testing.

In order to achieve the above object, an information terminal according to the present invention executes a command based on an input operation, a storage means for storing operation history information, and at least an operation content, an operation time, and an operation at that time The first control that stores the predetermined screen information that has been transitioned by executing the operation history information in the storage unit, and when the malfunction is detected in accordance with the execution of the command, the stored in the storage unit Control means for executing second control for storing the operation history information stored at a time close to the time of occurrence of the failure and the setting at the time of occurrence of the failure as the failure log in the storage area of the storage means among the operation history information. wherein the control means, as a starting point the predetermined screen information selected from the fault log stored in the storage means, the same setting as when the predetermined screen information acquisition In terms of the, it is characterized that you reproduce the operation contents of up to trouble occurrence.

In addition, the information terminal control method according to the present invention executes an instruction based on an input operation, and at least the operation content at that time, the operation time, and the predetermined screen information transitioned by executing the operation as an operation history. Information stored in the storage means, and when a failure is detected with the execution of the command, the operation history information stored at a time close to the time of the failure occurrence and the setting at the time of the failure occurrence among the operation history information Save to the storage means as a defect log, and start from the predetermined screen information selected from the defect log stored in the storage means, and then set the same settings as when the predetermined screen information was acquired until the defect occurs It is characterized by reproducing the operation contents of.

  According to the present invention, it is possible to provide an information terminal capable of storing an operation procedure and operation timing when operated by a user and performing failure analysis and testing.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a diagram schematically illustrating the appearance of a mobile phone, which is an example of an information terminal according to an embodiment of the present invention. The mobile phone 1 is provided with an operation button 2 and a display 3.

The operation buttons 2 include a numeric keypad 2a for inputting a number, a confirmation button 2b for confirming selected items and character conversion, a direction button 2c for moving a cursor displayed on the display 3, a mail menu button 2d for opening a mail menu screen, and the like. Consists of

  FIG. 2 is a block diagram showing the configuration of the mobile phone 1 according to the embodiment of the present invention. As shown in FIG. 2, the mobile phone 1 includes a control unit 51. The control unit 51 controls the entire mobile phone 1. In addition, an audio signal processing unit 52, a transmission / reception unit 53, a display unit 54, a storage unit 55, an operation unit 56, an external interface unit 57, and a timer unit 58 are connected to the control unit 51.

  The audio signal processing unit 52 inputs and outputs audio signals using a speaker for calling, a microphone, a speaker for guidance, and the like. The transmission / reception unit 53 includes an antenna that communicates with a base station (not shown), and transmits and receives radio signals. The display unit 54 includes the display 3 and the like, and shows the operation status of the mobile phone 1, operation guidance, input information, received messages, and the like to the user. The operation unit 56 includes an operation button 2 and the like, and inputs commands and information. The storage unit 55 is configured by a rewritable nonvolatile memory such as a flash memory, for example, and stores various settings such as an incoming call volume and telephone directory data, and application programs. A command input from the operation unit 56 by a user operation input is executed by the control unit 51. The external interface unit 57 performs control for connecting to an external device in a wired or wireless manner, and can connect another mobile phone or a computer. When receiving the current time transmission command from the control unit 51, the time measuring unit 58 transmits the current time measured internally to the control unit 51.

  The operation of the control unit 51 when the cellular phone 1 having the above configuration reads the operation procedure and operation timing will be described with reference to FIGS.

  FIG. 3 is an example of screen transition of the mobile phone 1 shown in FIG. When the control unit 51 detects that the mail menu button 2d of the operation buttons 2 has been pressed, the control unit 51 causes the display 3 to display the mail menu screen P101. On the mail menu screen P101, a list of mail-related functions such as “received mail” and “transmitted mail” is shown, and these functions can be selected with a cursor. When the mail menu screen P101 is displayed on the display 3, when the direction button 2c is pressed, the cursor is moved, and when the confirmation button 2b is pressed, the screen shifts to a function screen where the cursor is set.

  For example, when the “down button” of the direction button 2c is pressed twice while the cursor is at the position of the received mail as in P101, the cursor is set to the item “create new mail” as in P102. When the confirm button 2b is pressed in this state, a new mail creation screen P103 is displayed on the display 3.

  As described above, when any operation is performed using the operation button 2 or voice recognition input, the control unit 51 stores the operation history information in the storage unit 55. At this time, the operation history information stored in the storage unit 55 is information of operation timing and operation contents as shown in FIG. FIG. 4A shows the operation used for the screen transition of FIG. 3 as an operation history. The operation was performed by pressing the “down button” of the direction button 2c twice and pressing the confirm button 2b once. This is the operation history content. As shown in FIG. 4A, the operation history information may be stored not only for the history information of pressing the button but also for the history information of releasing the button.

  However, the information stored as the operation history is not limited to the operation content of the operation unit 56. The control unit 51 stores the contents and timing of the program automatically started by the timer setting in the storage unit 55. In addition, in order to analyze a radio signal transmission / reception failure, the control unit 51 may store the base station ID and the changed timing in the storage unit 55 when the base station to which the transmission / reception unit 53 is connected changes. This information helps to determine whether the cause of the radio signal transmission / reception failure is in the base station or in the mobile phone 1.

The information stored in the storage unit 55 to represent the operation content is preferably a number or an abbreviation in order to reduce the amount of information to be stored, rather than the natural language as shown in FIG. Here, an example in which the operation content is represented by an abbreviation is shown in FIGS. 4B and 4C. If the date and time overlap with the previous operation as shown in FIG. 4B, the operation timing may be stored without storing that part. Further, as shown in FIG. 4C, a method of storing the elapsed time from the previous operation may be used.

  FIG. 5 is a diagram illustrating a state in which the operation history of the mobile phone 1 is stored in the storage unit 55. FIG. 6 is a flowchart showing the operation of the control unit 51 that stores a failure log until the failure occurs. The operation of the control unit 51 from when a user operation is detected by the operation unit 56 to when a malfunction occurs will be described with reference to FIGS. 5 and 6.

  The cellular phone 1 according to the present embodiment uses a time point when a screen such as a standby screen, a menu screen, and a mail menu screen is displayed on the display 3 as a test starting point when a test is performed based on the defect log. These screens are displayed when one of the operation buttons 2 of the mobile phone 1 is pressed. Since operations such as menu selection and mail creation are advanced from these screens, the point in time when these screens are displayed is considered to be the starting point of the operation.

  Therefore, when the control unit 51 detects that an operation such as changing the setting contents or state of each function has been performed from the operation unit 56 (S201), the screen display displayed on the display 3 is changed to the starting screen display. It is determined whether or not (S202). When it is determined that the screen has changed to the starting screen, the control unit 51 stores in the storage unit 55 what screen is displayed and the setting at that time as starting point information (S203). Further, the operation content and operation timing are stored in the storage unit 55 as an operation history (S204). The starting point information and the operation history are stored in an operation history storage area 55a provided in a part of the area of the storage unit 55, as indicated by P151 in FIG.

  After storing the operation history in the operation history storage area 55a, the control unit 51 executes processing according to the operation content input from the operation unit 56 (S205). When it is detected that a problem has occurred as the process is executed (Yes in S206), the operation history information related to the problem is stored in the storage unit 55 as data that cannot be overwritten (S208).

  This is because there is an upper limit on the amount of information that can be stored in the operation history storage area 55a. If the storage unit 55 has a sufficient capacity, all operation history information may be stored. However, if the operation history information is stored up to the upper limit capacity, the old operation history information is deleted in order each time new operation history information is stored. As a result, the operation history information related to the occurrence of a failure cannot be overwritten in order to prevent the operation history information (hereinafter referred to as the failure log) for a certain capacity from the time of the failure to be erased by the new operation history information. And

Note that the trouble log may be operation history information that is made a certain time before the trouble occurs.

  Even if the control unit 51 cannot detect the problem, some problem may occur. Therefore, when the user performs a specific operation from the operation unit 56 (S207), the control unit 51 stores the operation history information at that time in the storage unit 55 as an operation log in the same manner as when a failure is detected.

  Further, the control unit 51 adds information on what kind of trouble has occurred and the setting contents and state of the mobile phone 1 at the time of the trouble to the trouble log (S209, S210). At this time, the setting contents and state of the mobile phone 1 stored in the storage unit 55 are as shown in FIG. 7, for example. As described above, the control unit 51 stores the setting content and state of the function related to the mobile phone 1 in the storage area of the storage unit 55 without being limited to the setting content of the function operated immediately before.

  And the control part 51 leaves a malfunction log, and erases the past old operation history information from the operation history storage area 55a (S211). For this reason, only the failure log is stored in the operation history storage area 55a as shown in P153 of FIG.

  Thereafter, when detecting an input operation from the operation unit 56, the control unit 51 stores an operation log using an area in the operation history storage area 55a in which no defect log is stored, as in P154.

  FIG. 8 is a diagram illustrating an example of information recorded in the defect log. The content of the defect log recorded based on the flowchart of FIG. 6 includes starting point information, operation history, defect information, and settings when a defect occurs. Although FIG. 8 shows a case where a screen as a starting point is displayed only once in the defect log, how many times the starting point information is inserted depends on the operation content. When performing a test based on the defect log, the control unit 51 reads out the starting point information included in the defect log stored in the operation history storage area 55a, and starts the test therefrom.

  FIG. 9 is a flowchart showing the operation of the control unit 51 when testing the mobile phone 1 that has acquired the failure log in response to the failure analysis request.

  When a plurality of defect logs are stored in the mobile phone 1, which defect log is to be executed is selected by an input operation of the tester (S251). The test is performed from the screen that is the starting point included in the defect log. Therefore, from which starting point information the test is started is selected by the input operation of the tester (S252). Then, the control unit 51 reads the failure log from the starting point information from the storage unit 55 (S253), and converts the event so that it can be automatically executed by the mobile phone 1 (S254). Further, the setting of the starting point selected based on the starting point information is reproduced (S255). When it is detected that an operation button for automatic operation (not shown) is pressed (S256), an event is executed step by step (S257). The test ends when the event is executed and a failure occurs (S258) or when all the events of the failure log are executed (S259).

  Note that the step of pressing the operation button for automatic operation (S256) can be omitted, and the event execution can be automatically started.

  In addition, when converting the defect log into an event, it may be configured to specify at what timing the operation recorded in the defect log is to be executed. As the type of execution timing, a first execution timing for setting the time of the time measuring unit 58 at the same time as the time when the trouble log is stored and performing the same operation at the same time as the time stored in the trouble log, and storage There are provided a second execution timing at which the operation is performed at the time interval as described, and a third execution timing at which the operation is performed in the order of the change procedure without considering the time interval. Prior to event conversion of the defect log, the control unit 51 receives designation from the tester at which execution timing to execute, and performs event conversion based on the information. At this time, when the first execution timing is designated, the control unit 51 needs to set the clock of the time measuring unit 58 to the same date and time as the operation date and time stored in the trouble log.

  If the execution timing can be selected in this way, a test method can be set according to the content of the test, and the test time may be shortened.

  A configuration in which the number of test repetitions can be specified is also conceivable. When the number of repetitions is specified, the storage unit 55 stores the number of times, and the storage unit 55 also stores the number of test executions when the test is executed. Each time the test is completed, the control unit 51 refers to the storage unit 55 and compares the set number of repetitions with the number of executions. If the number of executions reaches the number of repetitions, the test ends.

In this way, it is possible to examine how often a failure occurs by configuring the same test repeatedly.

  In FIG. 9, the control unit 51 of the mobile phone 1 that stores the failure log converts the event and automatically executes the flow. However, the external interface unit 57 is used to connect to another device such as a computer, and the device In such a configuration, event conversion and instruction to the mobile phone 1 may be performed. In this case, the mobile phone 1 can only store fault logs, and can issue fault log event conversion and test execution instructions only from devices connected to the mobile phone 1.

  By adopting the configuration of such an embodiment, a failure log when a failure occurs can be stored in the information terminal. With this information, the operation can be reproduced in response to a failure log analysis request, and the cause of the failure can be identified and retested to resolve the failure.

  In addition, it is not limited to the said embodiment, You may change suitably in the range which does not deviate from the summary of this invention.
