Description

[Technical Field]

[0001] The present invention relates to a method and system for creating a checklist. [Background technology]

[0002] A checklist is a list of tasks or items to be checked for a task, and is used to prompt a user to ensure that all listed items are performed. In order to include all items in a checklist, it is necessary to grasp the overall picture of the task. For example, Patent Document 1 discloses a technology for creating such a checklist.

[0003] The technology in Patent Document 1 provides a function to import railroad crossing control data and automatically create a checklist for each control item using the imported data.

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-153740 Summary of the Invention [Problem to be solved by the invention]

[0005] Although Patent Document 1 shows the creation of a checklist using railroad crossing control data, it does not anticipate the creation of a checklist without using railroad crossing control data. Conventional checklists have been created manually, requiring an enormous amount of time, by cross-referencing multiple information sources, extracting necessary equipment information, and collating each piece of information.

[0006] Furthermore, the process of extracting necessary information and verifying each piece of information depends on the experience and knowledge of the worker, and insufficient experience or knowledge can result in checklists being over or underfilled.Therefore, there was a need for technology that could quickly create complete checklists that were not affected by the worker's level of knowledge.

[0007] Therefore, an object of the present invention is to provide a technique that can create a complete checklist in a short time, regardless of the knowledge level of the worker. [Means for solving the problem]

[0008] In order to solve the above problem, one representative checklist creation method of the present invention is a checklist creation method used to confirm the display pattern of a display screen including a plurality of symbols having change patterns in a checklist creation system including a symbol extraction unit, a symbol content acquisition unit, a change pattern information acquisition unit, and a checklist output unit, wherein the plurality of symbols included in the display screen are extracted, symbol content information including information indicating the display position and relationship of each of the plurality of symbols on the display screen is obtained, change pattern information indicating the change pattern of each of the plurality of symbols is obtained, and the display pattern of the display screen is output based on the symbol information and the change pattern information. [Effects of the Invention]

[0009] According to the present invention, a complete checklist can be created in a short time, regardless of the knowledge level of the worker. Problems, configurations, and effects other than those described above will become apparent from the following description of the preferred embodiment of the invention.

DETAILED DESCRIPTION OF THE INVENTION

[0011] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. However, the present invention is not limited to this embodiment. In addition, in the description of the drawings, the same parts are designated by the same reference numerals.

[0012] (Train operation system) In the following explanation, the present invention will be described as being applied to a train traffic control system. If an error is contained in the display on the operation status display screen of the train traffic control system, there is a risk of a serious accident occurring during train operation. Therefore, it is important to perform a full test of the equipment displayed on the screen (checking the initial display and checking display changes) to ensure the quality of the display screen.

[0013] The operation status display screen has drawing components arranged to display station names, track circuits, signals, directional levers, train number display windows, alarms, and other facilities for each station. Drawing components are the components used to display information such as the operating status of facilities and equipment. For this reason, it is necessary to use a full-test checklist to check the initial display and how the display changes with changes in input information for each drawing component (hereinafter also referred to as "symbol") provided for each facility and device.

[0014] The number of tests for a full-point test can reach tens of thousands on a single line, but in the past, all tests were manually listed on a checklist by cross-referencing an equipment list containing information on all equipment with an input / output information manual showing the display specifications for initial displays and when the display changes.

[0015] (Outline of the embodiment) An overview of an embodiment of a checklist creation system will be described with reference to Figure 1. Figure 1 is a diagram showing an overview of checklist creation. Information used to create a checklist is acquired from an operation status display screen 1, an equipment list 2, and an input / output information manual 3. As will be described in detail later, when the operation status display screen 1 is displayed on an output device such as a display unit, it is represented as a diagram with multiple symbols arranged on it. When the train traffic management system is in operation, the operation status display screen 1 changes to various display patterns, but when creating a checklist, it is sufficient to consider one display pattern. The facility list 2 also includes information on the contents of the drawing components included in the operation status display screen 1 (for example, information indicating the display positions and relationships of symbols on the display screen). The input / output information description 3 also includes information indicating a change pattern and a change condition that is a condition for generating the change pattern.

[0016] In the checklist creation system, the information contained in the operation status display screen 1, the equipment list 2, and the input / output information description 3 is imported into the checklist output tool 4. The checklist output tool 4 also has a checklist output request function 41. The checklist output request function 41 has the functions of importing information from the above three information sources (operation status display screen import function, equipment list import function, and input / output information description import function) and outputting a checklist (checklist output function). When the import function is executed, the information contained in the operation status display screen 1, the equipment list 2, and the input / output information description 3 is imported into the database 42. The information imported into the database 42 is then stored in a state where it can be correlated with each other. Therefore, the checklist output tool 4 can create and output a checklist 5 using the data contained in the database 42 without requiring user operation. The station equipment list information table, the equipment list information table, and the display change list information table contained in the database 42 will be described later.

[0017] In this way, the checklist output tool 4 can automatically create the perfect checklist 5 in a short time when developing the operation status display screen 1, regardless of the experience or knowledge of the person in charge.

[0018] (Operation status display screen) Next, the operation status display screen will be described with reference to Fig. 2. Fig. 2 is a diagram showing an operation status display screen example 11, which is an example of the operation status display screen 1 shown in Fig. 1. Fig. 2(a) shows an example of the arrangement of symbols on the operation status display screen, and Fig. 2(b) shows property information example 12, which is an example of property information that can be acquired from the operation status display screen. The operation status display screen example 11 is displayed on a display device such as a display, and accepts operations by a user (for example, an operations manager). The operation status display screen example 11 is created, for example, by arranging each pre-registered symbol on the screen using drawing software.

[0019] As each symbol, for example, symbols indicating equipment for displaying operation status such as traffic signals, track circuits, and station names, as well as equipment operated by the user, are registered.

[0020] With reference to Figure 2(a), the display "AA (station name)" indicates the name of the station where the equipment displayed by the operation status display screen example 11 is installed. The display "traffic light 1RA (upper row)" indicates that the equipment indicated by reference symbol 110 is a traffic light and is named 1RA. The display "traffic light 1RB (lower row)" indicates that the equipment indicated by reference symbol 111 is a traffic light and is named 1RB. The display "traffic light 2R" indicates that the equipment indicated by reference symbol 112 is a traffic light and is named 2R. The display "traffic light 3R" indicates that the equipment indicated by reference symbol 113 is a traffic light and is named 3R. The display "traffic light 2L" indicates that the equipment indicated by reference symbol 114 is a traffic light and is named 2L. The display "traffic light 3L" indicates that the equipment indicated by reference symbol 115 is a traffic light and is named 3L. The display "Traffic light 1LA (upper row)" indicates that the facility indicated by the reference numeral 116 is a traffic light and has the name 1LA. The display "Traffic light 1LB (lower row)" indicates that the facility indicated by the reference numeral 117 is a traffic light and has the name 1LA.

[0021] Furthermore, the designation "1T" indicates that the equipment indicated by reference numeral 118 is a track circuit and has the name 1T. The designation "2T" indicates that the equipment indicated by reference numeral 119 is a track circuit and has the name 2T. The designation "3T" indicates that the equipment indicated by reference numeral 120 is a track circuit and has the name 3T. The designation "4T" indicates that the equipment indicated by reference numeral 121 is a track circuit and has the name 4T. The designation "5T" indicates that the equipment indicated by reference numeral 122 is a track circuit and has the name 5T. The designation "6T" indicates that the equipment indicated by reference numeral 123 is a track circuit and has the name 6T. The designation "7T" indicates that the equipment indicated by reference numeral 124 is a track circuit and has the name 7T. The designation "8T" indicates that the equipment indicated by reference numeral 125 is a track circuit and has the name 8T. The designation "9T" indicates that the equipment indicated by reference numeral 126 is a track circuit and has the name 9T. The designation "10T" indicates that the equipment indicated by the reference numeral 127 is a track circuit and has the name 10T. The designation "11T" indicates that the equipment indicated by the reference numeral 128 is a track circuit and has the name 11T. The designation "12T" indicates that the equipment indicated by the reference numeral 129 is a track circuit and has the name 12T. The designation "13T" indicates that the equipment indicated by the reference numeral 130 is a track circuit and has the name 13T.

[0022] Furthermore, the display "Route 1 (1RA)" indicates that when traffic light 1RA is turned on, the route indicated by reference numeral 131 (from track circuit 3T to track circuit 4T and to traffic light 2R) is passable. The display "Route 2 (1RB)" indicates that when traffic light 1RB is turned on, the route indicated by reference numeral 132 (from track circuit 6T to track circuit 7T and to traffic light 3R) is passable. The display "Route 3 (1LA)" indicates that when traffic light 1LA is turned on, the route indicated by reference numeral 133 (from track circuit 8T to track circuit 7T and to traffic light 2L) is passable.

[0023] Also, reference numeral 134 indicates the position of the train. Here, it shows that the train is on track circuit 2T and will proceed to either route 1 or route 2 by operating signal 1RA or 1RB. Reference numeral 135 indicates a decision button, and reference numeral 136 indicates a cancel button. These buttons are used when the operation manager decides (confirms) or cancels an operation performed on the equipment.

[0024] With reference to FIG. 2(b), property information shown in property information example 12 is set for symbols arranged on operation status display screen example 11. The property information is set for each symbol and includes the equipment type, such as a signal or track circuit, the equipment name, which is a unique name set for each piece of equipment and does not overlap with other pieces of equipment, whether mouse click operation is enabled when the input device is a mouse, and other information required for each type of equipment. For example, the property information for signal 1RA includes the equipment name "1RA," that mouse click operation is enabled, and that it is a starting point or ending point in the train's travel range. For signal 1LA, the same property information as for signal 1RA is set, in addition to the equipment name.

[0025] The property information for track circuit 1T is set to the equipment name "1T," ​​mouse click operation is disabled, and the equipment is placed adjacent to the equipment to form the train's running range. The same property information as for track circuit 1T is set for track circuit 3T as well, except for the equipment name.

[0026] The property information of the station name, the decision button 135, and the cancel button 136 is set so that mouse clicks are valid for all of them.

[0027] Although the case where property information is set for each track circuit has been described, the method of setting property information is not limited to this. For example, track circuits 2T, 3T, and 6T, which make up the common part of route 1 and route 2, may be registered as separate symbols, or may be registered as a single symbol. The same applies to other symbols.

[0028] An example of an operation status display screen 11 shows the arrangement of symbols at station name AA, but generally, the arrangement of each symbol differs from station to station. As will be described later, symbols are specified by their arrangement and change pattern. For this reason, for example, in the case of traffic signals, since there are limited change patterns, it is possible to create symbols that are common to all stations. Also, in the case of track circuits, some stations have complex track circuit arrangements while others have simple ones, making it difficult to use common symbols for all stations, and in some cases symbols are created for each station.

[0029] (Signal and track circuit change patterns) Next, referring to Figure 3, we will explain the change patterns of traffic signal and track circuit symbols. While the traffic signal and track circuit symbols themselves can be common between stations, the display mode of traffic signals may change depending on the related facility information set for each symbol, or the display mode may change depending on the mouse selection status and the train running status. In other words, since traffic signals have display modes that correspond to various conditions, when creating an operation status display screen that includes traffic signals, it is necessary to extract a checklist that covers all display modes without omission. Since there are also various display modes for track circuits and other equipment, creating a checklist and checking the display modes is essential when developing an operation status display screen.

[0030] Fig. 3 is a diagram showing the display patterns of route 1 and route 2 included in the operation status display screen example 11 shown in Fig. 2 as a track circuit display example 13. In Fig. 3, a portion of the operation status display screen example 11 including track circuits 1T, 2T, 3T, 6T, traffic light 1RA, traffic light 1RB, route 1, and route 2 is extracted and shown. For example, the display in the upper part of Fig. 3 shows a state in which track circuits, signals, and routes 1 and 2 are virtually uniformly displayed, and the display in the middle part shows that when traveling on route 1, route 1 including track circuits 2T and 3T is passable (hereinafter also referred to as "progressible state"). And the display in the lower part shows that when traveling on route 2, route 2 including track circuits T2 and 6T is passable.

[0031] When Route 1 is in operation (middle row), traffic on Route 1 is controlled by traffic signal 1RA, so traffic signal 1RA and track circuit 3T indicate "passable," while traffic signal 1RB and track circuit 6T indicate "non-passable." For example, as shown in "When Route 1 is in operation," traffic signal 1RA is shown with a symbol containing a white circle, and track circuit 3T is shown with a solid line. Traffic signal 1RB is shown with a symbol containing a black circle, and track circuit 6T is shown with a dashed line.

[0032] Also, when a train is traveling on Route 2, which is controlled by Signal 1B, Signal 1RB and track circuit 6T indicate that it is open to traffic, while Signal 1RA and track circuit 3T indicate that it is closed to traffic. For example, as shown in "When Traveling on Route 2," Signal 1RB is shown with a symbol containing a white circle, and Track circuit 6T is shown with a solid line. Signal 1RA is shown with a symbol containing a black circle, and Track circuit 3T is shown with a dashed line.

[0033] In this way, when traveling on Route 1, the route display indication is applied to track circuits 2T and 3T on the Route 1 side, and when traveling on Route 2, the route display indication is applied to track circuits 2T and 6T on the Route 2 side. For this reason, two display patterns must be added to the checklist. Note that the above-mentioned passable and impassable indications are used for ease of understanding, and the present disclosure is not limited to this case.

[0034] For other symbols, it is necessary to extract check items that cover all display patterns.

[0035] (Equipment list) Next, equipment list 2 will be described with reference to FIG. 4. FIG. 4 is a diagram showing an example of equipment list 2. Equipment list 2 lists the equipment included in operation status display screen 1. Items include "No.", "Station," "Equipment Name," "Equipment Type," "Information Source," and "Related Equipment." "No." is a serial number in equipment list 2. "Station" indicates the station where the equipment is installed. "Equipment Name" indicates the name of the equipment. "Information Source" indicates the position on the screen where the relevant equipment is displayed on the display device. "Related Equipment" refers to equipment related to the relevant equipment; for example, if the equipment is a traffic light, the traffic light located in an opposing position corresponds to the related equipment. Furthermore, if the equipment is a track circuit, the adjacent track circuit corresponds to the related equipment.

[0036] For example, No. 1 is signal 1RA located at station AA, and its information source is 1 group, 1 bit, and its related equipment is 72R. Related equipment 72R is listed as No. 99 in Equipment List 2. Reverse position hold 72R has an information source of 6 groups, 1 bit.

[0037] (Input / Output Information Manual) Next, the input / output information manual 3 will be described with reference to FIG. 5. FIG. 5 is a diagram showing an example of the input / output information manual 3. The input / output information manual 3 includes the following items: "No.", "Equipment type," "Change pattern," and "Change condition." "No." is a serial number in the input / output information manual 3. "Equipment type" indicates the type of equipment. "Change pattern" is a display pattern on a display device, and can also be called output information for the equipment. "Change condition" indicates the conditions under which a "change pattern" occurs, and can also be called input information for the equipment. The output information and input information for the equipment are collectively called input / output information.

[0038] For example, traffic light No. 1 has a change pattern in which the ball part of the traffic light symbol changes from a normal color (e.g., white) to a red display, and both display patterns are represented by a line width of 2 dots. The red display pattern is set as the display pattern for the traffic light's initial state. Furthermore, traffic light No. 2 has a change pattern in which the ball part of the traffic light symbol changes from a normal color to a flashing red display pattern, and both change patterns are represented by a line width of 2 dots. When the information source information is in the ON state (in other words, traffic light No. 2 is in the ON state) and the related facility information is in the ON state (in other words, the related facility for traffic light No. 2 is in the ON state), the flashing red display pattern is adopted. Each piece of equipment continuously transmits its current status to the operation status confirmation screen, and the ON state, for example, in the case of a traffic signal, indicates that it is possible to proceed, and in the case of a track circuit, indicates that a train is present on that track circuit. The OFF state, for example, in the case of a traffic signal, indicates that it is impossible to pass, and in the case of a track circuit, indicates that a train is not present on that track circuit.

[0039] The initial state is set for each piece of equipment. For example, for track circuit No. 5, the initial state can be set to either the presence or absence of a train on the track circuit.

[0040] Although the Equipment List 2 and the Input / Output Information Description 3 have been explained, the contents and formats of the Equipment List 2 and the Input / Output Information Description 3 generally differ depending on the operator and line section. For this reason, in this disclosure, Equipment List 2 and Input / Output Information Description 3 that are in a predetermined format are used.

[0041] (Checklist output tool) Next, the operation of the checklist output tool 4 will be described with reference to FIGS.

[0042] FIG. 6 is a diagram conceptually showing the capture of an operation status display screen. The checklist output tool 4 extracts multiple symbols included in the operation status display screen (display screen) 1. Specifically, the checklist output tool 4 extracts property information of the symbols included in the operation status display screen 1. The method for extracting the property information can be set appropriately, and for example, a function provided in drawing software that converts screen drawing information into a database may be used. The checklist output tool 4 registers the extracted property information in the corresponding area 431 of the station equipment list information table 43 in the checklist output tool 4.

[0043] Each of the multiple symbols is a drawing component that represents one of the facilities including signals, track circuits, directional levers, buttons, train number display windows, and alarms. The relevant area 431 also has the following items: "No.", "Facility Name," "Facility Type," "Departure Point," "Destination Point," "Adjacent (Right)," and "Adjacent (Left)." Each of these items corresponds to property information. Note that items other than those listed may also be included in the station facility list information table.

[0044] The station facility list information table 43 contains information that can be associated with the facility list information table 44, which will be described later.

[0045] Next, Fig. 7 is a diagram conceptually showing the import of the equipment list 2. The checklist output tool 4 acquires symbol information including information indicating the display position and relationship of each of a plurality of symbols on the display screen. Specifically, the checklist output tool 4 imports the equipment list 2 and acquires the symbol information. The method for importing the equipment list 2 can be set appropriately, and for example, a file import function provided in database software may be used. The checklist output tool 4 registers the acquired symbol information in the corresponding area 441 of the equipment list information table 44 in the checklist output tool 4.

[0046] The information included in area 441 is information indicating the properties of the symbols (hereinafter also referred to as "symbol information"). The symbol information includes information indicating the installation location (station) of each of the multiple symbols, the facility name (name), the facility type, the information source which is the display position on the screen, and the related facilities.

[0047] Next, FIG. 8 is a diagram conceptually showing the import of the input / output information description 3. The checklist output tool 4 acquires change pattern information that indicates the change patterns of each of the multiple symbols. Specifically, the checklist output tool 4 imports the input / output information description and acquires the input / output information (hereinafter also referred to as "change pattern information"). The method for importing the input / output information description 3 can be set appropriately, and for example, a file import function provided in database software may be used. The checklist output tool 4 registers the acquired change pattern information in the corresponding area 451 of the display change list information table 45 within the checklist output tool 4.

[0048] The change pattern information included in the area 451 includes information indicating the facility type, the change pattern of each of the multiple symbols, and the conditions under which the change pattern occurs.

[0049] Next, Fig. 9 is a diagram conceptually showing the output of a checklist. The checklist output tool 4 outputs a display pattern for the display screen based on the symbol information and change pattern information. Specifically, the checklist output tool 4 acquires equipment to be checked, such as signals and track circuits, from the station equipment list information table 43. The equipment to be checked can be all equipment included in the station equipment list information table 43.

[0050] Next, the checklist output tool 4 uses the equipment to be checked as a key to extract, as check items, information on the information source and related equipment from the equipment list information table 44, and change patterns and change conditions from the display change list information table 45. The information in the equipment list information table 44 and the information in the display change list information table 45 can also be associated using, for example, the "equipment type" item.

[0051] Next, the checklist output tool 4 edits the acquired information and outputs it as a checklist. The checklist output method can be set appropriately, and for example, the information acquired on a station-by-station basis can be output as a checklist 5 using the file output function of the word processing software provided in the database software.

[0052] In Checklist 5, traffic lights 1R and 1L and track circuits 1T and 2T have been extracted as the equipment to be checked. For traffic lights 1R and 1L, four confirmation items have been extracted: Confirmation A "In the initial state change conditions, the ball part is red and the line width is 2 bits," Confirmation B "In the change conditions when information source information is ON and related equipment information is ON, the ball part flashes red and the line width is 2 bits," Confirmation C "In the change conditions when information source information is ON and related equipment information is ON, the ball part is green and the line width is 2 bits," and Confirmation D "In the change conditions when information source information is ON, the ball part is green and the line width is 2 bits."

[0053] Furthermore, for track circuits 1T and 2T, two confirmation items have been extracted: Confirmation A "In the initial state change conditions, the line part is white and the line width is 4 bits" and Confirmation B "In the occurrence conditions of information source information ON, the line part is red and the line width is 4 bits." The equipment to be checked shown in the checklist 5 is only a partial list, and all of the equipment included in the station equipment list information table 43 is also included in the equipment to be checked.

[0054] The checklist output tool 4 outputs alarm information if any of the multiple symbols is not associated with either the symbol information or the change pattern information, if the symbol information and the change pattern information contain errors, or if the output change pattern contains overlapping information. In such cases, there will be an excess or deficiency in the checklist items, and the alarm information is output to notify the user.

[0055] (Checklist output flowchart) Next, the checklist creation process will be described with reference to Fig. 10. Fig. 10 is a flowchart showing the process of the checklist output tool 4.

[0056] In step S1, the checklist output tool 4 captures the operation status display screen 1 and extracts a plurality of symbols included in the operation status display screen 1. Specifically, the checklist output tool 4 acquires property information of the symbols included in the operation status display screen 1. The property information is registered in the station facility list information table 43.

[0057] Next, in step S2, the checklist output tool 4 imports the equipment list 2 and acquires symbol information for a plurality of symbols. The symbol information includes information indicating the display position on the operation status display screen 1 and the relationship between the symbols. The symbol information is registered in the equipment list information table 44.

[0058] Next, in step S3, the checklist output tool 4 reads the input / output information description 3 and acquires change pattern information. The change pattern information is information that indicates the change pattern of each of the multiple symbols, and is registered in the display change list information table 45.

[0059] Next, in step S4, the checklist output tool 4 outputs a change pattern based on the symbol information and change pattern information. For the equipment to be checked, the checklist output tool 4 extracts, as check items, information on the information source and related equipment from the equipment list information table 44, and the change pattern and change conditions from the display change list information table 45. The extracted information is output as a checklist 5.

[0060] (System Configuration) Next, referring to FIG. 11, a case where the checklist output tool 4 is configured as a system will be described. FIG. 11 is a diagram showing an example of the configuration of a checklist output system. The checklist output system 500 is a system for creating a checklist used to confirm the display pattern of a display screen including a plurality of symbols having change patterns. The checklist output system 500 includes a processor and a memory, and the memory includes instructions for causing the processor to function as a symbol extraction unit 701 that extracts the plurality of symbols included in the display screen, a symbol content acquisition unit 702 that acquires symbol information including information indicating the display position and relationship of each of the plurality of symbols on the display screen, a change pattern information acquisition unit 703 that acquires change pattern information indicating the change pattern of each of the plurality of symbols, and a checklist creation unit 704 that outputs the change pattern based on the symbol information and change pattern information.
