Description

  The present invention relates to a history information display apparatus and method capable of displaying history information such as operations performed on the apparatus.

  Devices such as POS (Point Of Sales) terminals, ATMs (automated teller machines), or vending machines are operated by operators such as employees or users. An operator may perform an incorrect operation or an illegal operation, and a failure may occur in the apparatus due to the operation. In order to investigate the cause of the failure that has occurred, the operator may be asked to confirm the operating procedure, but if the time has passed or particularly many operations are involved, the operating procedure that was performed must be It is extremely difficult to grasp. Therefore, it is necessary to examine all possible operation procedures, and it takes a lot of time to investigate the cause.

  In order to investigate the cause in a short time, there is a history information display device that makes it possible to accurately grasp the operation performed on the device by storing and displaying the history of the operation etc. . For example, as a first conventional technique, there is a user operation log visualization device that can specify a position of a video clicked by the user from a user click operation log for the video. The user operation log visualization device reproduces a video that the user has performed a click operation, and the click position indicated by the log data in the video of the reproduction time indicated by the log data of the click operation performed by the user on the video. A mark indicating that is superimposed and displayed (for example, see Patent Document 1).

  As a second conventional technique, there is a failure analysis support device that can reproduce an operation performed by a user in order to investigate the cause of a failure. This failure analysis support device records a user's operation history and a history such as display on the operation panel, and automatically checks the operation input from the user on the operation panel when investigating the cause of the failure that occurred. (For example, see Patent Document 2).

  As a third conventional technique, there is a plant control monitoring device that executes a plant operation control operation by a touch operation on a screen of a display device. This plant control monitoring device stores the type of screen on which a touch operation is performed, the touch coordinates of the screen, the time, and the content of the operation, so that the performed operation can be reproduced on the screen (for example, a patent) Reference 3).

  As a fourth conventional technique, there is a recording / reproducing apparatus. This recording / reproducing apparatus reproduces the operation up to the occurrence of an error including the operation timing by storing the operated content in the memory including the operation continuation time (for example, Patent Document 4). reference).

  As a fifth conventional technique, there is a failure analysis support apparatus that can analyze a failure of a computer system, particularly an application. This failure analysis support apparatus records the operation procedure of an application as a log file in the customer side system, and reproduces the operation procedure in the development side system based on the recorded log file. Information recorded in the log file includes screen data, user operation, processing history, and processing time (see, for example, Patent Document 5).

  FIG. 5 shows a log instruction example 52 notified to the log generation unit 121 from the input / output unit 11 or the display control unit 16 shown in FIG. The log instruction basically indicates one log instruction per line, and FIG. 5 shows six log instructions. One log instruction is composed of a plurality of numerical values or character strings separated by commas. The first numerical value indicates an input / output unit number, which will be described later in FIG. 6, the second numerical value indicates an operation number, which will be described later in FIG. 7, and the third and subsequent numerical values or character strings are details of the operation.

  For example, in the log instruction “1, 1, 142, 244” on the first line, the operation of the operation number “1”, that is, the “touch” operation occurs at the input / output number “1”, that is, the touch panel unit 111, and the operation details are “142,244”, that is, the touched position is the coordinates (142,244). The log instruction on the second line is “1, 2, 145, 242”, the log instruction on the third line is “11, 11, 01F45CCD4EF10E042”, and the log instruction on the fourth line is “21, 31, 130”. The log instruction on the fifth line is “1,1,582,289”, and the log instruction on the sixth line is “1,2,573,295”.

  FIG. 6 is an input / output unit name definition table 53 stored in the character string conversion table unit T122 shown in FIG. The input / output part name definition table 53 is a table indicating a corresponding “input / output part name log character string” for each “input / output part number” for specifying the input / output part. On the right side of the input / output part name definition table 53, the names of the respective input / output parts are described as “Remarks: Corresponding input / output”. Since the character string in the input / output unit name log character string column of the table can be set arbitrarily, the input / output unit name log character string may be set to a character string that has nothing to do with it.

  For example, the input / output unit number “001” indicates that the input / output unit name log character string is “operation” and the remarks are “touch panel”, that is, the touch panel unit 111. Similarly, the input / output unit name log character string and remarks for the input / output unit number are ““ serial1 ”” and “serial communication unit 1” for “011”, and “serial2” for “012”, respectively. "" And "Serial Communication Unit 2", "013" is "external" and "Serial Communication Unit 3", and "021" is "Display" and "Display Unit" Yes, “031” is “sslan” and “SS-LAN communication section”, and “100” is “core” and “application”.

  “Serial communication unit 1”, “Serial communication unit 2”, and “Serial communication unit 3” are all serial communication units 116, and show a case where a plurality of input / output channels are used in the same device. . An input / output unit number is assigned to each of a plurality of input / output channels to distinguish them.

  FIG. 7 is an action name definition table 54 stored in the character string conversion table unit T122 shown in FIG. The action name definition table 54 is a table indicating a corresponding “action name log character string” for each “action number” for specifying an action. On the right side of the action name definition table 54, each action name is described as “Remarks: Corresponding action”. Since the character string in the action name log character string column of the table can be arbitrarily set, the action name log character string may be set to a character string that is completely unrelated.

  For example, the operation number “000” indicates that the operation name log character string is ““ message ”” and the remark is “information”. Similarly, the action name log string and remarks for the action number are “pressed” and “touch” for “001” and “released” and “release” for “002”, respectively. Yes, “011” is “read” and “input”, “012” is “write” and “output”, and “021” is “error” and “Error”. “031” is “change” and “screen change”.

  FIG. 8 is an operation detail creation rule table 55 stored in the character string conversion table unit T122 shown in FIG. The operation detail creation rule table 55 is a table showing “operation details log creation rule” for each combination of “input / output unit” and “operation”. The meaning of each combination is described as “Remarks: Meaning” on the right side of the operation detail creation rule table 55.

  For example, for the combination of the input / output unit “001” and the operation “001”, the log creation rule for the operation details indicates that the third and fourth arguments are in the format of coordinates “x =% 04d, y =% 04d”. The remark is “touch the touch panel”. Similarly, the operation detail log creation rule and remarks for each combination of the input / output unit and the operation are as follows. For the combination of the input / output unit “001” and the operation “002”, the coordinates of the third and fourth arguments are “X =% 04d, y =% 04d” format ”and“ touch panel is released ”. For the combination of the input / output unit“ 012 ”and the operation“ 011 ”,“ the third argument is set to a hexadecimal number ” And “input in the serial communication unit 1”, and for the combination of the input / output unit “012” and the operation “012”, “set the third argument to hexadecimal” and “output in the serial communication unit 1” The combination of the input / output unit “012” and the operation “021” is “set the third argument to a decimal number” and “error in the serial communication unit 1” and operate with the input / output unit “021”. Combination with “031” , “3rd argument is set to“ display =% 04d ”format” and “screen change in display unit”. For the combination of input / output unit “031” and operation “011”, “3rd argument is set to 16 For the combination of the input / output unit “031” and the operation “012”, “set the third argument to hexadecimal” and “SS-LAN communication”. The combination of the input / output unit “100” and the operation “000” is “output the third argument as characters” and “application information”.

When the log generation unit 121 receives a log target log set in the log setting unit 124 from the input / output unit 11 or the display control unit 16, the log generation unit 121 first acquires the date and time from the system timer unit 13 and represents the date and time. Generate date and time log string. Next, based on the first numerical value of the received log instruction, the input / output unit name log character string from the input / output unit name definition table 53 shown in FIG. 6 and the second numerical value are shown in FIG. The action name log character string is acquired from the action name definition table 54. Further, based on the first numerical value, the second numerical value, and the third and subsequent numerical values or character strings of the received log instruction, the operation detail creation rule table 55 shown in FIG.
An operation detail log representing the details of the operation is created according to the operation detail log creation rule. The acquired date / time log character string, input / output unit name log character string, operation name log character string, and created operation detail log are combined to generate a log corresponding to the log instruction. The generated log is stored in the log file unit T15.

  For example, when generating a log indicating that the operator has touched the touch panel, the instruction log is the instruction log “1, 1, 142, 244” on the first line of the instruction log example 52 illustrated in FIG. FIG. 8 shows combinations of the number “001” representing the input / output unit “touch panel” indicated by the first argument “1” and the number “001” representing the operation “touch” indicated by the second argument “1”. Referring to the operation detail creation rule table 55, the operation detail log creation rule “the third and fourth arguments are in the format of coordinates“ x =% 04d, y =% 04d ”” is obtained. Here, “% 04d” indicates a 4-digit decimal number, and is an example of a standard output format related to character output in a program using C language. Assuming that the date and time is 15: 15: 01.120 seconds on May 18, 2006, from the third argument “142” and the fourth argument “244”, the log is “2006/05/18, 15:05:01. 120, “operation”, “pressed”, “x = 00142, y = 0244”.

  FIG. 9 shows an example log 56 stored in the log file portion T15 shown in FIG. The log example 56 basically shows one log for one line, that is, a log for one operation on the target machine 10, and FIG. 9 shows six logs. One log is composed of a plurality of numerical values or character strings separated by commas. The first numeric value or character string is the date and time when the operation to be logged occurred, the second numeric value or character string is the input / output part name, the third numeric value or character string is the operation name, the fourth numeric value or character string These are the operation details which show the content of each operation | movement in detail. In the example shown in FIG. 9, four items are exemplified, but in addition to these, information related to the target machine 10 such as a related program name, a user name, the number of characters of the log, or a machine name in the log, and a use situation Or you may include the information etc. which specify a place. Furthermore, when the information amount of one log increases, the log may be divided into two or more lines.

  FIG. 9 shows a log example 56 corresponding to the instruction log example 52 shown in FIG. The first line is “2006/05/18, 15: 05: 01.120,“ operation ”,“ pressed ”,“ x = 00142, y = 0244 ””, and the second line is “ 2006/05/18, 15:05: 01.541, “operation”, “released”, “x = 0145, y = 0242” ”. The third line is“ 2006/05/18, 15 : 05: 02.951, “serial1”, “read”, “01F45CCD4EF10E042”, and in the fourth line, “2006/05/18, 15: 05: 04.092,“ display ”,“ change ” ”,“ Display = 0130 ”” and the fifth line contains “2006/05/18, 15: 05: 08.735,“ operation ”. , “Pressed”, “x = 0582, y = 0289” ”, and the sixth line contains“ 2006/05/18, 15: 05: 09.090, “operation”, “released”, “x = 0573, y = 0295 "".

  In the example shown in FIG. 9, an example in which information specifying the date and time is included in the log is shown, but when the information for specifying the date and time is not included in the log, the log is recorded in the log file of the log file unit T15 In this case, the data is stored in the order in which the logs are generated or in the order in which the operations to be logged occur. When information for specifying the date and time is included in the log, the order may be arbitrary.

  FIG. 10 shows a log event conversion table 57 used by the application unit 14 shown in FIG. 3 to create a log instruction. The log event conversion table 57 is a table indicating a “log character string” corresponding to each “event” generated in the application control unit 142. In the log character string column, an arbitrary log character string can be set according to the event. Therefore, the application can be recorded as a log independent of the input / output unit 11, that is, only the application information can be recorded as a log.

  FIG. 10 shows the log character string ““ Program A start ”” for the event “Start of program A”, and the log character string ““ Program A end (end code =%) for the event “End of program A” ”. 03d) "" is displayed, the log character string "" employee code =% 06d "" is displayed for the event "designation of employee to operate", and the log character string "" is specified for the event "start of checkout process" Checkout process start "" is shown.

  FIG. 11 shows a log instruction example 58 notified from the application unit 14 shown in FIG. 3 to the log generation unit 121 and a log example 59 based thereon. For example, when the target machine 10 is a terminal used in a restaurant composed of a plurality of employees, in order to identify the operator of the terminal, the application uses the employee information, for example, the employee code to identify the employee. to manage. The operation of the touch panel is an operation related to the employee who uses the terminal, and there is a case where the input / output operation performed on the touch panel and the employee information are associated with each other and recorded in a log. When the log recording control unit 12 is not configured to know the employee information, the application control unit 142 records information that exists only in the application, for example, employee information as an arbitrary character string in order to record in the log. The log generation unit 121 is instructed by a log instruction.

  Each log instruction shown in the log instruction example 58 includes a plurality of numerical values or character strings separated by commas, as in the example shown in FIG. The first numerical value indicates the input / output unit number shown in FIG. 6, the second numerical value indicates the operation number shown in FIG. 7, and the third numerical value and the character string are details of the operation. The details of the operation are information corresponding to the event shown in FIG. For example, the log instruction “100, 0,“ Program A start ”” on the first line is an input / output number “100”, that is, an application, generates an operation with an operation number “0”, that is, “information”. “Program A started”, that is, program A has started. The log instruction on the second line is “100, 0,“ employee code =% 06d ”, 138”, and the log instruction on the third line is “100,0,“ program A end (end code =% 03d) ”. , 0 ".

  Each log shown in the log example 59 is a log corresponding to the log instruction shown in the log instruction example 58. Similarly to the example shown in FIG. 9, a plurality of numerical values or character strings separated by commas are used. Composed. The first numeric value or character string is the date and time when the operation to be logged occurred, the second numeric value or character string is the input / output part name, the third numeric value or character string is the operation name, the fourth numeric value or character string These are the operation details which show the content of each operation | movement in detail. For example, “2006/05/26, 10: 13: 59.022,“ core ”,“ message ”,“ Program A start ”” is indicated on the first line, and “2006/05” is indicated on the second line. 05/26, 10: 14: 21.924, “core”, “message”, “employee code = 000138” ”is shown on the third line,“ 2006/05/26, 10:20:11 311, “core”, “message”, “program A end (end code = 000)”.

The

  By making the screen information shown in FIG. 15 the same image number as the display image number in the image management table 51 shown in FIG. 4, the display screen at the time of log recording and the display screen at the time of log reproduction can be matched. it can. The information about the screen display included in the log is unique information from which the screen image displayed on the screen of the target machine 10 at the time when the log is recorded. Has been identified. The file name of the file containing the screen image displayed on the screen of the target machine 10 at the time when the log is recorded, or the file name of the file containing some information that can identify the image is displayed on the screen table 61. The image is shown in the image file name. Therefore, if a screen image having the image image file name corresponding to the specified screen information is read out and displayed on the display unit S25, it is displayed on the screen of the target machine 10 when the log is recorded. Screen image can be played.

  Various image formats such as PNG (Portable Network Graphics) format, GIF (Graphic Interchange Format) format, or JPEG (Joint Photographic Experts Group) format can be used as the image format of the screen image of the image image file name.

  15, “0001.PNG” is shown as the screen image file of the screen information “screen 0001”, “0002.GIF” is shown as the screen image file of the screen information “screen 0002”, and the screen information “screen 0003” is shown. "0003.JPG" is shown as a screen image file of "."

  FIG. 16 schematically illustrates an example of a procedure for generating the playback screen 70 displayed on the screen display unit 71 illustrated in FIG. 13. The log reproduction control unit 28 uses the screen table 61 shown in FIG. 15 to display the target machine 10 displayed when the log is recorded from the log of the log file read from the target machine 10 into the buffer unit 22. Derive the screen above.

  FIG. 16 shows a log file 15a, a screen image file database 24a, a reproduction image 70a, and a reproduction image 70b. The log file 15a includes two logs “2006/05/22, 14: 49: 42.789,“ display ”,“ change ”,“ display = screen 0001 ”” and “2006/05/22, 14:53. : 02.024, “display”, “change”, “display = screen 0002” ”are recorded. The screen image file database 24a stores a screen table 61, a screen image “0001.PNG”, a screen image “0002.GIF”, and a screen image “0003.JPG”.

  For example, when the log analysis unit 23 analyzes the first log of the log file 15 a read into the buffer unit 22, the log reproduction control unit 28 displays “screen on May 22, 2006 at 14: 49: 42.789”. It becomes clear that “0001” is displayed. The screen image file database 24a is searched using the screen information “screen 0001” as a key to obtain a related screen image file name “0001. PNG”. That is, it is derived that the screen displayed on the target device 10 at the time of log recording is an image of the file “0001.PNG”. The log reproduction control unit 28 acquires the image image having the screen image file name “0001.PNG” from the screen image file database 24a, and displays it on the display unit S25 as the reproduction image 70a. Similarly, the reproduction image 70b is displayed on the display unit S25 for the second log.

  The reproduction image 70a is an image image “screen 0001” displayed on the display unit T113 of the target device 10 at “14: 49: 42.789 seconds on May 22, 2006”, and the reproduction image 70b is “2006 This is the image “screen 0002” displayed on the display unit T113 of the target machine 10 on May 22, 14: 53: 02.024 ”.

  FIG. 17 shows an example of another screen table 62 stored in the image image file DB 24 shown in FIG. The screen table 62 includes screen information defined by information for specifying the background of the screen or information for specifying a window as a part, and a screen image file name for specifying a file for storing the screen image. As in the screen table 61 shown in FIG. 15, the table displayed at the time of log recording is specified from the log and used to generate a reproduction image. The screen image file name is a name of a file determined in advance for each screen image. In the file indicated by the screen image file name, a screen background displayed on the target machine 10 or a part such as a window, button, or text is displayed. The same or equivalent image is recorded.

  In FIG. 17, “B0001.PNG” is shown as the screen image file of the screen information “background 0001”, “B0002.PNG” is shown as the screen image file of the screen information “background 0002”, and the screen information “background 0003” is shown. "B0003.PNG" is shown as the screen image file of "", "W0001.PNG" is shown as the screen image file of the screen information "window 0001", and "W0002.PNG" is shown as the screen image file of the screen information "window 0002". "It is shown.

  The screen table 62 is different from the screen table 61 shown in FIG. 15 in that the image file indicated by the image file name in the screen table 62 is a component indicating a part of the entire image image displayed on the screen. It is where you are. The reproduction image is generated by combining the image image used as the background and the image image of the window displayed in front of the background. That is, a plurality of image images obtained from a plurality of screen information recorded in a log are superimposed. Therefore, since image images can be used in common, the number of image images stored in the screen image file database 24 can be reduced or the data size of each data can be reduced.

  FIG. 18 schematically shows another example of the procedure for generating the playback screen displayed on the screen display unit 71 shown in FIG. The log reproduction control unit 28 uses the screen table 62 shown in FIG. 17 and the target machine 10 displayed when the log is recorded from the log of the log file read from the target machine 10 into the buffer unit 22.

The screen image file database 24b is searched using the screen information “background 0001” as a key to obtain a related screen image file name “B0001.PNG”. Similarly, the screen information “window 0001” is searched for as a key to obtain an image file name “W0001.PNG”. The log reproduction control unit 28 acquires an image image with the screen image file name “B0001.PNG” and an image image with the image image file name “W0001.PNG” from the screen image file database 24b, and obtains two image images. The screen is superimposed and displayed on the display unit S25 as a playback image 70c, and the screen displayed on the target machine at the time of log recording is played back. Similarly, the reproduction image 70d is displayed on the display unit S25 for the second log.

  The reproduction image 70c is the image image “background 0001” and “window 0001” displayed on the display unit T113 of the target device 10 at “14: 49: 42.789 seconds on May 22, 2006”, and the reproduction image 70d.

FIG. 22 is a log when the operator operates the operation button displayed on the touch panel in response to a message for the operator “please enter the password” displayed on the display unit T113 of the target machine 10. An example in which the operation is displayed on the touch panel operation image 251 displayed on the screen display unit 71 is shown.

  The touch panel operation image 251a indicates that the operation button “2” on the touch panel of the screen image displayed on the operation unit S25 is operated with a finger-shaped pointer. The touch panel operation image 251c indicates that the “*” portion of the touch panel of the screen image displayed on the operation unit S25 is touched by the pointer.

  The touch panel operation image 251b is an image in which an afterimage of the moved pointer is superimposed and displayed on a route from the position of the pointer shown in the touch panel operation image 251a to the position of the pointer shown in the touch panel operation image 251c. Actually, the finger-shaped pointer sequentially moves on the path from the position of the pointer on the touch panel operation image 251a to the position of the pointer on the touch panel operation image 251c.

  FIG. 23 shows an example of a key operation image according to the conventional technique displayed on the key operation display unit 72 shown in FIG. FIG. 23 shows a key operation image 253 displayed on the key operation display unit 72 based on the log when the key “0” is pressed after the key “9” of the key unit 112 of the target machine 10 is pressed. Shows an example of displaying the operation.

  The key operation image 253a indicates that the key “9” in the key portion of the screen image displayed on the operation unit S25 has been operated with a finger-shaped pointer. The key operation image 253b indicates that the key “0” in the key portion of the screen image displayed on the operation unit S25 has been operated with a finger-shaped pointer.

  FIG. 24 shows an example of a key operation image according to the present invention displayed on the key operation display unit 72 shown in FIG. Similarly to the case of FIG. 23, FIG. 24 also shows the key operation display unit 72 based on the log when the key “0” is pressed after the key “9” of the key unit 112 of the target machine 10 is pressed. An example in which the operation is displayed on the key operation image 253 displayed in FIG. The key operation image 253c is the same as the key operation image 253a shown in FIG. 23, and the key operation image 253e is the same as the key operation image 253b shown in FIG.

  The key operation image 253d is an image in which an afterimage of the moved pointer is superimposed on a path from the position of the pointer shown in the key operation image 253c to the position of the pointer shown in the key operation image 253e. Actually, the finger-shaped pointer sequentially moves on the path from the pointer position of the key operation image 253c to the pointer position of the key operation image 253e. The pointer displayed on the path from the position of the pointer of the key operation image 253c to the position of the pointer of the key operation image 253e is a pointer displayed at the position of the pointer of the key operation image 253c and the position of the pointer of the key operation image 253e. Are displayed separately. In this example, the shape of the pointer displayed on the route is made smaller than the pointer shape displayed at the pointer position of the key operation image 253c and the pointer position of the key operation image 253e. Further, the pressed key is displayed separately from other keys. In this example, the key color is changed for display.

  FIG. 23 does not show the way from the position of the pointer in the state of the key operation image 253a to the position of the pointer in the state of the key operation image 253b. Therefore, if the key operation continues many times, the pointer may be lost. is there. However, in FIG. 24, since the pointer is moved and displayed between the operated key and the next operated key, the operator does not lose sight of the pointer.

  FIG. 25 shows a key coordinate conversion table 66 stored in the character string conversion table unit S27 shown in FIG. The key coordinate conversion table 66 is a table showing a correspondence between a key code for identifying a key and converted coordinates (X, Y) indicating the position of each key in the key operation image displayed on the key operation display unit 72. is there.

  When the keys are operated in the order of “9” and “0”, as logs, “2006/06/08, 17: 14: 03.787,“ key ”,“ pressed ”,“ keycode = 0x0019 ””, “2006 / 06/08, 17:14: 07.924, “key”, “pressed”, “keycode = 0x0010” ”are generated. Normally, a key is assigned to a key code inside the machine. In this example, for example, ““ keycode = 0x0019 ”” is taken as a log, and key “9” is an internal key code “19 (hexadecimal number)”. It shows that there is. Similarly, the log “keycode = 0x0010” indicates that the key “0” is the key code “10 (hexadecimal)”.

  For each key code, the coordinate position of the corresponding key displayed on the screen in advance is stored as the key coordinate conversion table 66 shown in FIG. When ““ key ”,“ pressed ”” or ““ keycode = ”” is detected from the log, it is converted into coordinates corresponding to the key code based on the key coordinate conversion table 66 shown in FIG.

In the above-described embodiment, the target machine 10 is exemplified by a POS terminal used in distribution or a gas station, but is not limited to this.
(Automated teller machine), vending machines, kiosk terminals, safety monitoring devices at self-gas stations, POS terminal training support devices for remote locations, and information devices such as personal computers or portable terminals, etc. Any device that operates can be used. The remote POS terminal training support apparatus is an apparatus for previously storing an operation performed by the lecturer as a log and reproducing the operation procedure of the lecturer using the operation log during the training.

  Further, the log display system 1 is configured by connecting the target machine 10 and the support machine 20 by connecting them via the LAN 30. However, the function of the support machine 20 is included in the target machine 10 and the target machine 10 and the support machine 20 are connected. 20 may be integrated. When there are a plurality of target machines 10, only one target machine 10 may be integrated.

  FIG. 26 shows a schematic configuration of a log display system 2 which is another embodiment of the present invention. The log display system 2 that is a history information display device stores a log file in a storage device outside the target machine, and includes a target machine 10 a, a support machine 20, and a network disk 40 that are respectively connected via a LAN 30. The display method of history information is processed by the log display system 2. The support machine 20 is the same as the support machine 20 shown in FIG. 3, and is not shown. The target machine 10a is obtained by eliminating the log file portion T15 of the target machine 10 shown in FIG. The log transmission unit T18 is the same as the LAN communication unit 114 shown in FIG. 3, and transmits the log generated by the log generation unit 121 to a network disk 40 connected to a network such as the LAN 30 or a public line.

  The network disk 40 is connected to the LAN 30 and includes a log file unit N41 and a log communication unit N42. The log file unit N41 is configured by a storage device such as a hard disk device, for example, and stores the log received by the log communication unit N42 from the target machine 10a. The log communication unit N42 is a communication unit that transmits and receives data to and from other devices connected to the LAN 30, such as the target device 10 and the support device 20. Thus, log recording can be performed without providing a storage area in the target machine 10a.

  FIG. 27 shows a schematic configuration of a log display system 3 which is still another embodiment of the present invention. The log display system 3, which is a history information display device, is a system that eliminates a log file, and includes a target machine 10b and a support machine 20a that are respectively connected by a LAN 30. The display method of history information is processed by the log display system 3. The target machine 10b is the same as the target machine 10a shown in FIG. As will be described in detail with reference to FIG. 28, the support device 20a is provided with a log receiving unit S29 instead of the log reading unit 21 and the buffer unit 22 of the support device 20 shown in FIG. The target device 10b transmits the generated log to the support device 20a by the log transmission unit 18 without storing the generated log.

  FIG. 28 is a block diagram showing an example of the configuration of the support machine 20a shown in FIG. A log receiving unit S29 is provided instead of the log reading unit 21 and the buffer unit 22 of the support machine 20 shown in FIG. The log receiver S29 of the support machine 20a receives the log transmitted from the target machine 10b and sends it to the log analyzer 23. The log analysis unit 23 analyzes the log received from the log reception unit S29 and sends the analysis result to the log reproduction control unit 28. The log reproduction control unit 28 performs display based on the analysis result received from the log analysis unit 23. That is, the log display system 3 can display the operation performed on the target machine 10b on the display unit S25 of the support machine 20a in real time. Therefore, it is possible to monitor the operation of the target machine 10b at a location away from the target machine 10b. It becomes easy to use for the purpose of monitoring logs.

  FIG. 29 is a flowchart of the input / output log instruction creation processing of the input / output unit 11 shown in FIG. When the input / output unit 11 performs processing related to the log instruction, the process proceeds to step A1. In step A1, a hardware or software interrupt is awaited. In step A2, it is determined whether or not an interrupt has occurred. If there is an interrupt, the process proceeds to step A3. If there is no interrupt, the process returns to step A1. In step A3, an interrupt is processed. In step A4, a log instruction is created based on the processing content that generated the interrupt. In step A5, the log generation unit 121 is notified of the log instruction and the process ends.

  FIG. 30 is a flowchart of the log instruction creation process of the application unit 14 shown in FIG. When the application unit 14 performs display on the screen of the display unit T113, the process proceeds to step B1. In order to perform screen display, the display control unit 16 is notified of the display image number, thereby specifying the screen to be displayed. This designation is performed by an arbitrary application operating on the target machine 10.

  In step B1, image data specified by the image management table 51 shown in FIG. 4 is acquired from the image data unit 141 based on the display image number. In step B2, the image data is adjusted according to the display unit T113. Adjustment means that the image is the whole or a part of the image, and that the image is enlarged, reduced, or superimposed in accordance with the display capability of the display unit T113. In step B3, the adjusted image data is displayed on the display unit T113. In step B4, a log instruction is created based on the display image number. In step B5, the generated log instruction is notified to the log generation unit 121 and the process ends.

  FIG. 31 is a flowchart of the log monitoring process of the log recording control unit 12 shown in FIG. The log recording control unit 12 monitors each unit in the input / output unit 11, and proceeds to Step C1 to generate a log of the operation to be logged.

  In step C 1, the log setting is acquired from the log setting unit 124. In the log setting, all of the operations related to the log, for example, operations related to the input / output unit 11, or errors are set, and the log target operation can be selected by setting the log target in the log setting. In step C2, the operation of the input / output unit 11 is confirmed. That is, the operation of each unit in the input / output unit 11 is monitored. In step C3, it is determined whether or not there is a log target operation. If there is a log target operation, the process proceeds to step C4. If there is no log target operation, the process returns to step C2.

  In step C4, a log is generated for the operation to be logged. In step C5, it is determined whether or not a recording destination log file is specified in the log setting. If specified, the process proceeds to step C7, and if not specified, the process proceeds to step C6. In step C6, the generated log is recorded in the standard log file 151 and the process ends. In step C7, the generated log is recorded in the designated log file 152 and the process ends.

  FIG. 32 is a flowchart of the log recording process of the log recording control unit 12 shown in FIG. When the log instruction from the input / output unit 11 or the display control unit 16 is monitored, the process proceeds to Step D1.

  In step D1, a log instruction is waited. In step D2, it is determined whether or not there is a log instruction. If there is a log instruction, the process proceeds to step D3, and if there is no log instruction, the process returns to step D1. In step D3, the log setting is acquired from the log setting unit 124. In step D4, it is determined whether or not the log instruction is a log instruction to be logged. If it is a log target, the process proceeds to step D5, and if it is not a log target, the process returns to step D1.

  In step D5, a log is generated for the detected operation to be logged. In step D6, it is determined whether or not a recording destination log file is specified in the log setting. If specified, the process proceeds to step D8, and if not specified, the process proceeds to step D7. In step C7, the generated log is recorded in the standard log file 151 and the process ends. In step C8, the generated log is recorded in the designated log file 152 and the process ends.

  Both the flowcharts shown in FIG. 31 and FIG. 32 are processes by the log recording control unit 12, but operate in separate tasks. However, the start of each flowchart may be connected to the end of another flowchart to continuously operate as one task.

FIG. 33 is a flowchart of the log generation processing of the log generation unit 121 illustrated in FIG.
Called when generating a log in step C4 shown in FIG. 31 or step D5 shown in FIG. 32, the process proceeds to step E1. Therefore, the process is started in a state where the log instruction or the log target operation is specified.

  In step E1, the current date and time is acquired from the system timer unit 13. The date / time does not necessarily have to be the date / time by the system timer unit 13, and any unique date / time that can specify the date / time when the operation to be logged has occurred may be used. The unique date and time is, for example, the elapsed time since the target machine 10 started operating, the date and time according to the clock of the server machine on the same network, or the operating time of the server.

  In step E2, a date / time log character string is created from the acquired date / time. In step E3, the input / output unit log character string corresponding to the input / output unit number is acquired with reference to the input / output unit name definition table 53 shown in FIG. In step E4, the action log character string corresponding to the action number is acquired with reference to the action name definition table 54 shown in FIG. In step E5, with reference to the operation detail creation rule table 55 shown in FIG. 8, the operation detail log string creation rule corresponding to the combination of the input / output unit number and the operation number, that is, the operation detail log creation rule is acquired. To do.

  In step E6, an operation detail log character string is created based on the acquired operation detail log creation rule. In step E7, the date / time log character string created in step E2, the input / output unit log character string obtained in step E3, the operation log character string obtained in step E4, and the operation detail log character string created in step E6 are combined. Generate a log and exit.

  FIG. 34 is a flowchart of the log reproduction process of the log reproduction control unit 28 shown in FIG. For example, when the log reproduction function is selected by the operation unit 26, the process proceeds to step F1.

  In step F1, a log file name selection screen for selecting a log file name to be reproduced is displayed on the display unit S25. In step F2, the operation unit 26 waits for a log file name to be selected. If the log file to be played back is specified before the function to play back the log is selected, for example, before moving to Step F1, Step F1 and Step F2 may be skipped.

  In step F3, it is determined whether a plurality of log files have been selected. When a plurality of log files are selected, the process proceeds to step F19, and when one log file is selected, the process proceeds to step F4. In step F4, the selected log file is read into the buffer unit 22. In step F5, the date and time when the log recording was started and the date and time when the log recording was completed, that is, the date and time of the last recording were acquired from the buffer unit 22. Since the logs in the buffer unit 22 are sorted in order of date and time, the date and time of the first row and the date and time of the last row are acquired.

  In step F6, a reproduction condition input screen for inputting reproduction conditions is displayed. The reproduction condition is, for example, a condition that a log having an input date and time from the start to the end of the log is reproduced, or a condition that a log that matches or includes the inputted character string is reproduced. In step F7, it is determined whether or not a reproduction condition is specified. If the reproduction condition is designated, the process proceeds to step F8, and if the reproduction condition is not designated, the process proceeds to step F20. In step F8, a log that matches the specified playback condition is searched from the logs in the buffer unit 22, and when the top log of the buffer unit 22 is the first line, the value of the line number of the searched log is “ The value obtained by subtracting “1” is assigned to the counter “n”.

  In step F9, "1" is added to the counter "n" and the pointer is advanced to the next line. In step F10, the log of the “n” line is read from the buffer unit 22 for one line. In step F11, the log analysis unit 23 analyzes the read log. The analysis reveals what the log was doing. In Step F12, it is determined whether or not another line log is necessary for reproduction. Since one operation may be divided and recorded in a log having two or more lines, it is determined whether or not another line is necessary. There are cases where playback is not possible if there are not enough logs. If another line log is necessary, the process returns to step F9, and if another line log is not necessary, the process proceeds to step F13.

  In step F13, it is determined whether or not the log is a screen display, that is, whether or not the operation indicated by the log is related to the screen display. If the log is a screen display log, the process proceeds to step F14. If the log is not a screen display log, the process proceeds to step F15. In step F14, since the information about the screen image is included in the log, the screen image indicated by the information is acquired from the screen image file DB 24. In step F15, a reproduction screen image to be displayed is generated from the acquired screen image and the operation indicated by the log. In step F16, the generated reproduction screen image is displayed on the display unit S25.

  In step F17, it is determined whether all the logs in the buffer unit 22 have been read. If all the logs have not been read, the process proceeds to step F18, and if all the logs have been read, the process ends. The log file selection screen can also be displayed by returning to the start at the end. In step F18, the process waits for wait w seconds and returns to step F9. In step F19, all the selected log files are read into the buffer unit 22, the logs are sorted using the date and time of each log line as a key, and the process proceeds to step F5. In Step F20, “0” is substituted into the counter “n”, and the process proceeds to Step F9.

  The process shown in FIG. 34 can be ended at an arbitrary scene by an operation by the operation unit 26 as will be described later with reference to FIG. 36, and can be temporarily stopped and re-executed from the temporary stop. In addition, along with the log file selection, you can specify the logs in the log file by file size, number of lines, or date and time recorded in the log, and read logs from the log file to any log in the log file. It is also possible to start with.

  With regard to the playback speed, it is possible to insert an arbitrary time or a fixed time specified by the operation unit 26, for example, wait w seconds, between the steps shown in FIG. 34, during the loop, or before and after the jump. The speed can be adjusted. By setting the time w used for the weight based on the date and time recorded in the log, it is possible to reproduce the log in real time. The value of w can be arbitrarily changed by the operation unit 26 when starting the processing of the flowchart or during the loop processing from Step F9 to Step F18.

  FIG. 35 is a flowchart of the operation reproduction interpolation process of the log reproduction control unit 28 shown in FIG. The operation reproduction interpolation process is a process of reproducing by complementing the display between logs during log reproduction. This process is effective when reproducing the log of the input / output unit 11 in which the operator performs a plurality of operations at discrete positions. The touch panel unit 111 and the key unit 112 are suitable parts of the input / output unit 11. Or a mouse not shown. In the process in step F16 shown in FIG. 34, the touch panel unit 111, the key unit 112, or a mouse (not shown) or the like is called to display the operated position, and the process proceeds to step G1.

  In step G1, the loop flag “m” is set to “0”. In step G2, the playback speed s is set by the operation unit 26. A default value may be set in advance, and the default value may be used to skip step G2. In step G3, the pointed position is analyzed by the log analysis unit 26, and the coordinates of the analyzed point are substituted into X and Y. In step G4, it is determined whether m = 0. If m = 0, the process proceeds to step G11. If m = 0, the process proceeds to step G5. If step G4 has been executed even once, “m” is not “0”.

  In Step G5, “0” is set to the loop counter “t”. In step G6, “1” is added to the loop counter “t”. In step G7, coordinates (Xa, Ya) are calculated from the previously displayed coordinates (X0, Y0) and the coordinates (X, Y) obtained from the current log. The coordinate (Xa, Ya) is a position on the path connecting the coordinate (X0, Y0) and the coordinate (X, Y), and is divided at predetermined intervals, for example, among eight divided points. One position. For example, Xa = ((X−X0) * t) / s + X0 and Ya = ((Y−Y0) * t) / s + Y0. In step G8, the previous reproduction is deleted. This step may be skipped if it does not need to be erased. A pointer such as a finger or a cross is displayed or reproduced at the coordinates (Xa, Ya). By displaying the pointer displayed at this time in distinction from the pointer displayed in step G11, for example, by displaying the pointer at a reduced size, it can be known that the display is an interpolation display.

  In step G10, it is determined whether t <s. If t <s, the process returns to step G6. If t <s, the process proceeds to step G11. In step G11, the log content is reproduced at coordinates (X, Y). Specifically, an image display such as a finger or a cross or a numerical value of coordinates is displayed. In step G12, X of coordinates (X, Y) is saved to X0, and Y is saved to Y0. In step G13, “1” is substituted for “m”, indicating that the process of step G11 has been executed at least once. In step G14, it is determined whether all the logs in the buffer unit 22 have been read. If all the logs in the buffer unit 22 have been read, this flowchart is terminated. If all the logs in the buffer unit 22 have not been read, the process returns to step G2 to repeat the process.

  FIG. 36 is another example of the flowchart of the log reproduction process of the log reproduction control unit 28 shown in FIG. This log reproduction process is a flowchart for visualizing a log generated by the target machine 10 (hereinafter also referred to as “log data”) and reproducing it on the support machine 20. For example, when the log reproduction function is selected by the operation unit 26, the process proceeds to step H1.

  In step H1, log data is read. In step H2, it is determined whether or not the log data is final log data. If it is the final log data, the process ends. If it is not the final log data, the process proceeds to step H3. In step H3, it is determined whether or not the read log is a log indicating that screen display has been performed. If the log indicates that the screen display has been performed, the process proceeds to step H13. If the log indicates that the screen display has been performed, the process proceeds to step H4.

  In step H4, it is determined whether or not the read log is a log indicating a touch on the touch panel unit 111 or a release from the touch panel unit 111. If the log indicates a touch on the touch panel unit 111 or a release from the touch panel unit 111, the process proceeds to step H15. If the log indicates a touch on the touch panel unit 111 or a release from the touch panel unit 111, the process proceeds to step H5. In step H5, it is determined whether or not the read log is a log indicating that the key unit 112 is pressed. If the log indicates that the key unit 112 has been pressed, the process proceeds to step H16. If the log indicates that the key unit 112 has not been pressed, the process proceeds to step H6.

  In step H6, since it is determined that the log read in the condition determination in steps H3 to H5 is not a screen display log and a log related to the touch panel unit 11 and the key unit 112, the log is displayed on the screen of the support device 20. Only the communication message portion, that is, the operation detail log character string in the read log data is cut out and displayed in the arranged device-specific message display area, that is, the input / output display unit 73. In step H7, the processing is paused for the time of the reproduction interval designated by the log reproduction control unit 28 of the support device 20.

  In Step H8, the playback screen of the support device 20 is refreshed and displayed with the image updated in Step H6, Step H14, Step H15, or Step H16. In step H9, it is determined whether or not the end button has been pressed on the playback screen of the support device 20. If the end button is pressed, the process ends. If the end button is not pressed, the process proceeds to step H10. In Step H10, it is determined whether or not the stop button has been pressed on the playback screen of the support device 20. If the stop button is pressed, the process proceeds to step H11. If the stop button is not pressed, the process returns to step H1.

  In step H11, the process is paused and a pause screen is displayed. In Step H12, it is determined whether or not the resume button has been pressed on the temporary stop screen of the support machine 20. If the restart button is pressed, the process proceeds to step H8, and if the restart button is not pressed, the process returns to step H11.

  In step H13, the image image file database 24 of the support device 20 is searched, and an image image included in the image file having the same file name as the screen file name included in the read log, that is, the screen image file name is acquired. In step H14, the background image currently displayed on the support device 20 is replaced with the background image acquired in step H13, and the process proceeds to step H7. In step H15, the same location as the touch coordinate in the log is marked up, and the process proceeds to step H7. That is, a pointer (hereinafter also referred to as “pointer mark”) is displayed on the same coordinate position indicated by the log data on the background image of the playback device, that is, the support device 20, and the process proceeds to Step H7. The images displayed by the pointer marks are separate images when touched and released, and the images are displayed by the log reproduction control unit 28 of the support device 20. In step H16, the “key image arranged on the screen of the player” corresponding to the key number indicated by the log data is displayed in reverse, that is, black and white are displayed in reverse, and the process proceeds to step H7.

  FIG. 37 is a flowchart of the key coordinate conversion process of the log reproduction control unit 28 shown in FIG. The key coordinate conversion process is executed between Step G2 and Step G3 shown in FIG. 35. After Step G2 is executed, the process proceeds to Step J1, and when the key coordinate conversion process ends, the process returns to Step G3.

  In step J1, the log is read from the buffer unit 22. In step J2, it is determined whether the input / output name of the log is “key”. If the input / output unit name is “key”, the process proceeds to step J3. If the input / output unit name is not “key”, the process ends. In step J3, the hexadecimal value following “keycode =” is converted into coordinates, and the process ends.

  The process shown in FIG. 37 is inserted between step G2 and step G3 shown in FIG. 35, and color is given to the key operated in step G11, so that the key as shown in FIG. When the unit 112 is operated, the input operation from the key can be visualized.

  As described above, a plurality of operation units for inputting predetermined information are arranged at different positions by the operation unit such as the touch panel unit 111 or the key unit 112, and the log generation control unit 12 as the history generation unit, for example. For example, a log that is history information that represents the operation unit operated among the plurality of operation units of the operation unit in time series is generated, and an image is displayed and controlled by the display unit S25 that is a display unit. In response to the history information generated by the history generation unit by the log reproduction control unit 28, which is a means, for example, an operation unit image representing the plurality of operation units is displayed on the display unit, for example, the screen display unit 71 or the key On the operation display unit 72, for example, a pointer which is an operation position image indicating the position of the operated operation unit is displayed on the operation unit image. Since it is displayed at a predetermined display interval along a path connecting two operation units adjacent in series, when displaying history information such as operations performed on the device, losing sight of continued operations Can be displayed. Therefore, the operation procedure can be traced reliably, and the time for investigating the cause can be shortened.

  Further, when the operation unit includes, for example, the key unit 112 which is a key input device in which a plurality of keys are arranged, and when the key of the key input device is operated by the log recording control unit 12 which is a history generation unit, For example, a key code that is key identification information for identifying the operated key is generated as a log, for example, a key code is history information, and the history information is key identification information by, for example, a log reproduction control unit 28 that is a control means. The key position indicated by the key identification information is converted into the coordinate position of the two-dimensional coordinates of the operation unit image, and the operation position image, for example, a pointer is displayed on the converted coordinate position, for example, by display unit S25. Therefore, even if the operation position indicated by the history information is information specifying the key, the key position displayed on the screen can be pointed. Can. Therefore, the operation procedure can be reproduced for key input.

  Furthermore, when the pointer, which is the operation position image, is displayed by, for example, the display unit S25, which is the display means, by the log reproduction control unit 28, which is the control means, the operation position image when being moved is the operation position image. Is displayed in a manner different from the operation position image when the operation position is indicated, it is possible to distinguish and display the operation position and the movement path of the hand from the operation position to the next operation position. Therefore, confusion between operation and movement can be prevented.

  Further, for example, each log included in the input / output unit 11 is input / output information excluding information input by the operation unit from information input to or output from the device by the log recording control unit 12 which is a history generation unit. The input / output history information representing the information input / output by the communication unit is further generated by including, for example, a log in which the input / output history information representing the time series is the history information. In response to the input / output history information generated by the history generating means, for example, the input / output display area 73 representing the area to be displayed is displayed by the display section S25, for example, the display means. Since the input / output information indicated by the input / output history information is displayed on the display area image, the information input / output to / from the device is reproduced along with the operation procedure. Rukoto can. Therefore, factors other than the operation procedure can be taken into consideration, and the cause can be investigated more accurately.

  Furthermore, the history information display method is a plurality of operation units which are arranged at different positions in the history generation process and for inputting predetermined information, for example, operation buttons of the touch panel unit 111 or keys of the key unit 112. Operation that represents the plurality of operation units in response to the history information generated in the history generation step, for example, by generating a log that is history information that represents the operation units operated in time series For example, on the screen display unit 71 or the key operation display unit 72 that is a partial image, for example, a pointer that is an operation position image that indicates the position of the operated operation unit is displayed on the operation unit image. Since it is displayed at a predetermined display interval along the route connecting the operation units, when displaying history information such as operations performed on the device, it is displayed without losing sight of the continued operation. It can be provided as a method to. Therefore, the operation procedure can be reliably traced without being limited to the display device, and the time for investigating the cause can be shortened.
