Abstract

A diagram management server for a train line stores user information defining a relationship between a login user and an authority level; train line information; and authority setting information defining a relationship between a creation person having edit authority of the train line and an upper user in a database. When the login user is defined as an upper user of the creation person having the authority setting, a diagram edit terminal requests registering and updating of the train line information created by the creation person, based on the authority level of the login user, and the diagram management server resisters and updates the train line information. Then, from the database, the diagram edit terminal acquires and displays the train line information that the login user has the authority to edit.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is based upon and claims the benefit of priority from the prior Japanese Patent Application No. 2011-229904, filed on Oct. 19, 2011, the entire contents of which are incorporated herein by reference.

FIELD

Embodiments of the present invention relate to a train diagram edit system, a train diagram edit method, and a train diagram edit program.

BACKGROUND

In general, a railway operation company inputs data such as a departure time and an arrival time in each train station and a distance (kilometers) between adjacent stations to a server such as a work station, thereby creating diagram data in advance. Thereafter, the diagram data is displayed on a screen as an operation diagram (hereinafter referred to as a “diagram”). Using the diagram, a train operation is managed. For example, the diagram is a graph where a vertical axis represents a distance from a starting station (reference), a horizontal line represents a time, and an operation station name is on the vertical axis showing the distance between stations. One train operation is expressed as one line (train line) on the diagram.
In addition, an amount of the diagram data becomes quite large in proportion to the number of the operations of trains and the number of departure/arrival stations. Therefore, the diagram data is often created by a plurality of users by a collaborative work. Accordingly, a train diagram edit system is constructed by connecting a plurality of edit terminals to a server via networks to share the work. By using the network, the diagram data can be shared by the respective terminals placed in a company. In this case, the whole diagram data is managed exclusively, and consistency is kept. For example, the diagram edit system uses (1) a method of designating other users that can share the created diagram data upon registration, and allowing the users other than the creation person to refer a work status, (2) a method of temporarily lending other users a part of an edit authority of the diagram data, and exclusively managing the diagram data or the like.
The following documents relate to the above-described technology, the entire contents of which are incorporated herein by reference.

SUMMARY OF INVENTION

Problem to be Solved by the Invention

As described above, when the creation of the diagram data is shared by a plurality of users (creation persons) on the network, an arrangement work is necessary to provide one diagram as a whole by modifying and changing the data in order to keep the consistency of the diagram data created by each creation person. However, in the above-mentioned diagram edit system, it is difficult to do such a work on the terminals via the network, because only the train numbers and the operation numbers are added to the train line displayed on the screen of the system. Therefore, a department manager cannot find out a department where the creation person belongs to and a name of the creation person by only referring to the train line. In addition, the system did not have a structure that only the diagram data to be managed can be extracted from a large amount of data created by a plurality of creation persons for mutual comparison. In particular, the trains may be mutually operated across companies (or across countries) in recent years. Therefore, the collaborative work in this case may be accompanied by great difficulties.

The table 102C may be configured of a part of the above-described information, and the other information may be determined separately by calculation, or may be provided from other data base where necessary.
The authority levels held in the authority setting information table 102B and the user information table 102C in the diagram management server 1 are as follows:
[Authority 0]: An authority level representing the creation person, as the general user, who can edit only the train line where an own user ID is set in a user row of the authority setting information table 102B.
[Authority 3]: An authority level representing the department manager user who can edit all of the train lines where an own user ID is set in a department manager row of the authority setting information table 102B.
The user authentication unit 103 is a program to authenticate the user by referring to the user information table 102C based on the user ID and an input password of the user who uses the diagram edit terminal 3. The authority level of the login user acquired upon the authentication is output to the data extraction unit 104 together with the user ID.
The data extraction unit 104 extracts the train line information to be displayed from the train line operation plan table 102A at a diagram edit terminal 3 side depending on the authority level of the login user acquired by the user authentication unit 103, and sends the train line information to the diagram edit terminal 3 via the server side communication unit 101.
The data coupling possibility determination unit 105 is a program to determine whether it is possible to perform a train line coupling processing by acquiring an operation station, an order of operation, a departure time and an arrival time included in the train line information about the former train and the later train from the train line operation plan table 102A, when the train line information on a same date of the train operation to be coupled is acquired at the diagram edit terminal 3 side.
The data register and update unit 106 is a program to register and update the train line information upon register and update request from the diagram edit terminal 3.
The engagement person change message unit 107 is a program to notify an engagement person change message to the diagram edit terminal 3 used by the changed creation person, and to output new train line information in real time, when the creation person in the train line information stored in the train line operation plan table 102A is changed by register and update processing in the data register and update unit 106.
The diagram edit terminal 3 includes the terminal side communication unit 301, an input unit 302, a data edit unit 303, a train line acquisition unit 304, a train line display unit 305, a train line coupling unit 306 and a train line bulk coupling unit 307.
The terminal side communication unit 301 is an interface for data communication with the server side communication unit 101, sends data outputted from the input unit 302, the data edit unit 303, the train line acquisition unit 304, the train line display unit 305, the train line coupling unit 306 and the train line bulk coupling unit 307 to the server side communication unit 101, and outputs the data received form the server side communication unit 101 to each unit as appropriate.
The input unit 302 is an input interface for a terminal user to input information to the data edit unit 303, the train line acquisition unit 304, the train line coupling unit 306 and the train line bulk coupling unit 307 in a variety of an input screen etc.
The data edit unit 303 is a program to send train line information including the train numbers, the train operation dates, the operation stations, the departure times and the arrival times inputted by the upper user such as the department manager in the train line register and update screen and the authority setting information including the department, the authority level and the user ID to the diagram management server 1, and request the register and update of the train line information and the authority setting information stored in the data base unit 102. In this regard, a train line register and update screen is displayed under the condition that the user authentication is completed between the diagram management server 1 and the diagram edit terminal 3. FIG. 7 shows a specific example of the train line register and update screen displayed on the diagram edit terminal 3 shown in FIG. 1. Information about the train operation station (the departure/arrival station) and time are held in the train line operation plan table 102A. The train line is determined uniquely by a combination of the train number and the train operation date. The authority level, the department and the user ID for each train line are held in the authority setting information table 102B. Corresponding to registered information in the train line operation plan table 102A and the authority setting information table 102B, the user information table 102C also holds the relationship between the user ID and the upper user, i.e., the department manager as user default information, whereby the creation person and the department manager can be retrieved using the train number as a key at a diagram management server 1 side.
The data edit unit 303 has a function that edits the authority setting information and the train line information created by the creation person based on the input information by the department manager (the upper user), and requests the register and update processing of the edited data to the data register and update unit 106, when the login user is defined as the department manager (the upper user) of the creation person (the general user) in the authority setting information.
The train line acquisition unit 304 is a program to request extraction of all of the train lines where the login user has the edit authority to the data extraction unit 104 of the diagram management server 1, and to acquire the train line information stored in the data base unit 102 and the authority setting information corresponding thereto. The train line display unit 305 is a program to create and display the train line display screen based on the train line information and the authority setting information acquired at train line acquisition unit 304. Specifically, as the creation person is held per the train number in the authority setting information table 102B and the department is held per the user ID in the user information table 102C, the user ID is taken out from the authority setting information table 102B using the train number as a key, and the department information is taken out from the user information table 102C using the user ID as a key. Then, the information extracted at the diagram management server 1 side is sent to the diagram edit terminal 3 side, and the user ID of the creation person and the department where the creation person belongs to are displayed per the train line in the train line display screen.
FIG. 8 shows a specific example of the train line display screen displayed in the diagram edit terminal 3 shown in FIG. 1. Here, a vertical axis represents a distance, and a horizontal axis represents a time. Operation station names are put on the vertical axis in accordance with the order of operation. In addition, the train line information is represented by an arrow line within a coordinate. The train number, the user ID and the department are shown close to the train line, thereby finding out the user who is the creation person of the train line as well as the department the user belongs. Also, the authority setting information held at the diagram management server 1 is displayed on the screen of the diagram edit terminal 3 together with the train line information.
The train line coupling unit 306 is a program to couple the train line information about two trains operated on the same date created by the user having the authority level lower than the login user into new train line information based on a result of comparison of the orders of operation, the operation stations, the departure times and the arrival times, and to request the register and update of the data base unit 102 to the data register and update unit 106 based on the new train line information. Even if the train line information about two trains is created by the user having the authority level not lower than the login user, it may be coupled, where special permission is made. Before executing coupling processing, the data coupling possibility determination unit 105 of the diagram management server 1 is requested to determine whether or not it is possible to perform the coupling. The coupling is executed only when a notice that the coupling is possible is received from the data coupling determination unit 105. Specifically, when the department manager is the login user, two train lines created by the department manager's own department can be coupled into one train line, where the arrival time is before the departure time in the same station among the train lines in the same department shown on the screen of the diagram edit terminal 3.
FIGS. 9 and 10 are tables for illustrating data transitions of the train line operation plan table 102A and the authority setting information table 102B before and after the train line coupling processing, respectively. Here, shaded two records are coupled, and the new train line information is registered. The two records before coupling are deleted, and the train number 111A, which is the number of the former train, is taken over as a new train number of the new train line information.
Alternatively, the train number 112A that is the later train or the train number separately designated by the user may be used as the train number added to the new train line information. For example, when the creation persons of the two train lines are the user A and the user B, it is possible to disperse the workload by designating a user C. When the train number where the user ID of the department manager is set in a creation person row is used, it is possible to transfer the edit authority of the train line after the coupling to the department manager, and to limit the edit by the general user. In other words, the train line can be effectively created by sharing by a plurality of the general users, and can be advantageously adjusted finally by the department manager in a bulk management.
FIG. 11 shows specific examples of the train line coupling in the same department on the train line display screen displayed on the diagram edit terminal 3 shown in FIG. 1. Here, there is shown that the display on the screen is changed corresponding to the data transitions shown in FIGS. 9 and 10 above.
The train line bulk coupling unit 307 is a program to extract and display, as a candidate, other train operation date having the train number according to the coupling processing executed in the train line coupling unit 306 when the bulk coupling of the train line is requested by the login user on the train line display screen, and to execute the coupling processing similar to that executed in the train line coupling unit 306 about the train operation date selected by the user.
FIGS. 12 and 13 are tables for illustrating data transitions of the train line operation plan table 102A and the authority setting information table 102B before and after the train line bulk coupling processing per the train operation date, respectively. Here, shaded five records are on the train operation date (2011/07/02) designated by the user. The train lines (2 records) of the train number 112A on the same date are coupled to the train line of the train number 111A, and the new train line information is registered. In other words, the records show the case where the same processing as the train line coupling processing on the train operation date (2011/07/02) illustrated in FIGS. 9 and 10 applies to the case that other train operation date (2011/07/01) is designated.

FIG. 17 is a sequence diagram showing a specific example of the train line coupling processing in the diagram edit system shown in FIG. 1.
In S1701, the diagram edit terminal 3 selects any two or more of train lines to be coupled by a mouse operation etc. on the screen by the login user upon a train line coupling mode.
In S1702, the diagram edit terminal 3 sends the train number and the train operation date about the former train and the later train before coupling selected on the screen to the diagram management server 1.
In S1703, the diagram management server 1 acquires the train line having the largest number of order of operation among the operation station information about the former train from the train line operation plan table 102A based on the information received.
In S1704, the diagram management server 1 acquires the train line having the smallest number of order of operation among the operation station information about the later train from the train line operation plan table 102A based on the information received.
In S1705, the diagram management server 1 compares the operation station information acquired at S1703 and S1704, and determines whether or not the train lines can be coupled. Here, if it is determined that the train lines can be coupled, it proceeds to S1708. In contrast, if it is determined that the train lines cannot be coupled, it proceeds to S1706.
In S1706, the diagram management server 1 sends a notification that the train lines cannot be coupled, to the diagram edit terminal 3 used by the department manager.
In S1707, the diagram edit terminal 3 used by the department manager receives the notification that the train lines cannot be coupled, pops up the notification on the screen, encourages the department manager to re-select the train lines, and returns to S1701.
In S1708, the diagram management server 1 sends a notification that the train lines can be coupled, to the diagram edit terminal 3 used by the department manager.

Here, the train line information served as a basis for the new train line information will be deleted from the train line operation plan table 102A in order to avoid duplicate the data.
In S1711, the diagram management server 1 detects the person to be notified from the login users, and sends the engagement person change message to the diagram edit terminal 3 used by the person to be notified. The person to be notified may be the creation person of each train line before coupling, the creation person of the train line after coupling, etc., and can be set freely.
In S1712, the diagram management server 1 sends the changed train line information to the diagram edit terminals 3 used by the department manager and the person to be notified.
In S1713, the diagram edit terminal 3 used by the department manger displays the received train line information on the screen.
In S1714, the diagram edit terminal 3 used by the person to be notified (the general user) displays the received engagement person change message and the changed train line information on the screen.
In this way, when the department manager is logged in, all of the train lines in the department managed by the department manager are sent from the diagram management server 1 to the diagram edit terminal 3, the two train lines designated at the diagram edit terminal 3 are then received at the diagram management server 1, whether or not the coupling processing can be performed is checked at the server side, the coupling processing is executed, thereby coupling the two train lines into one.
FIG. 18 is a sequence diagram showing a specific example of train line bulk coupling processing per the train operation date in the diagram edit system shown in FIG. 1.
In S1801, the diagram management server 1 acquires the train line information about the former train and the later train before coupling in the coupling processing executed immediately before it. Here, the train line information before coupling may be saved temporarily in a memory area of any of the diagram management server 1 and the diagram edit terminal 3.
In S1802, the diagram management server 1 refers the train line operation plan table 102A, and acquires another train operation date having the train line information acquired at S1801.
In S1803, the diagram management server 1 sends the another train operation date acquired at S1802 to the diagram edit terminal 3.
In S1804, the diagram edit terminal 3 displays the another train operation date information on the screen.
In S1805, the diagram edit terminal 3 sends the another train operation date designated by a mouse operation etc. by the department manager from a list of the train operation dates displayed on the screen to the diagram management server 1.
In S1806, the diagram management server 1 executes train number bulk coupling processing executed immediately before to the train operation date received.
In this way, after the coupling processing by the diagram management server 1 shown in FIG. 17, bulk coupling processing is executed on the train having the same train number on the another train operation date, thereby further alleviating the workload in the diagram edit.
Accordingly, by the train diagram edit system according to the embodiment of the present invention, the following advantages are provided.
(1) When the authority setting information table 102B holds the authority level, the creation person (a name of a user created train line data) and the department manager of the train line creation (the upper user), the edit authority can be managed per the user and the department.
(2) The department manager of the train line creation can identify the user ID of the creation person (the general user) of the train line held in the authority setting information table 102B, and as the upper user, the department manager can change the creation person as appropriate.
(3) The creation person of the train line changed can take over quickly an edit work of the train line where the engagement is changed by receiving the engagement person change message in real time on the diagram edit terminal 3.
(4) The department manager can easily select and confirm the train line of the own department by displaying the authority level and the creation person held in the authority setting information table 102B.
(5) The creation person (the general user) can easily confirm and edit the train line engaged by oneself on the diagram edit terminal 3 by focusing the train line initially displayed based on the user ID and the authority level of the user logged in the diagram management server 1. Also, the train lines other than the train line engaged by oneself may be displayed for reference. In this case, the edit work of the train lines to be fit with those created by other users can be possible.
(6) The department manager can couple the train lines of the own department such that the train lines divided into plural lines can be coupled into one new train line.
(7) The coupling processing in (6) can also be applied to other train operation dates under the predetermined conditions. Therefore, when a plurality of dates can be designated, the bulk coupling processing of the train lines can be successively done on a plurality of the train operation dates.

Embodiment 2

In the diagram management system according to a second embodiment, only the configuration of the data base unit 102 included in the diagram management server 1 is different from the diagram management system according to the first embodiment, and the processing in the diagram management server 1 and the diagram edit terminal 3 is similar to the diagram management system according to the first embodiment. Accordingly, the points different from the first embodiment will be described in detail.
FIGS. 19 and 20 each shows a specific example of a stored content of the authority setting information table 102B and the user information table 102C in the train diagram edit system according to the second embodiment. Here, in the authority setting information table 102B shown in FIG. 5 and the user information table 102C shown in FIG. 6, a data item about a business manager who is the upper user of the department manager (a user having [Authority 6]) is added. Here, [Authority 6] is an authority level representing the business manager. The user having this authority level can edit all of the train lines where own user ID is set on a business manager row of the authority setting information table 102B.
FIGS. 21 and 22 are tables for illustrating data transitions of the train line operation plan table 102A and the authority setting information table 102B before and after the train line coupling, respectively. Referring to the authority setting information table 102B shown in FIG. 22 using a train number 111A acquired by a record stored in the train line operation plan table 102A shown in FIG. 21 as a key, it is found that the user ID of the creation person of the train line is a user A, and the user ID of the department manager is a user AAA. Accordingly, the business manager having the user AAA can edit all of the train lines created by the user A and user AA having the authority level of the general user in an own company regardless of the departments. In FIG. 21, when shaded three records are designated by the business manager, they are sequentially coupled by the processing similar to the first embodiment to update to two records of the same train number. FIG. 23 shows a specific example of the train line coupling in different departments in the train line display screen displayed on the diagram edit terminal 3 shown in FIG. 1. Here, there is shown that the display on the screen is changed corresponding to the data transitions shown in FIGS. 21 and 22 above. The number (111A) designated by the business manager as the train number is added to a new train line, and the creation person is changed to the user A only.
In this way, the train diagram edit system according to the second embodiment offers the following advantages in addition to the advantages offered by the first embodiment by defining the business manager as the upper user of the department manager in the data base unit 102.
(1) When the login user is the business manager, the train lines can be managed in a bulk across different departments in the same company.
(2) In the case of (1), the business manager can freely edit the train lines created by the own company and change the creation person even when the department manager is absent.

Embodiment 3

In the diagram management system according to a third embodiment, only the configuration of the data base unit 102 included in the diagram management server 1 is different from the diagram management system according to the first embodiment, and the processing in the diagram management server 1 and the diagram edit terminal 3 is similar to the diagram management system according to the first embodiment. Accordingly, the points different from the first embodiment will be described in detail.
FIGS. 24 and 25 each shows a specific example of a stored content of the authority setting information table 102B and the user information table 102C in the train diagram edit system according to the third embodiment. Here, in the authority setting information table 102B shown in FIG. 19 and the user information table 102C shown in FIG. 20, a data item about a supervisor (a user having [Authority 9]) is added. Here, [Authority 9] is an authority level representing the topmost user. The user having this authority level can edit all of the train lines where own user ID is set on a supervisor row of the authority setting information table 102B.
Here, a supposed supervisor will be described in detail, concerning to railway conditions in Europe, as an example. In Europe, railway transportation is liberalized, and railway operation companies can freely operate trains on infrastructure railways. In particular, in the train lines of cross-border international trains in Europe, railway companies of a plurality of countries require adjustments. If each company freely creates the train line, there is higher likelihood that operational problems may happen. For example, the train lines operating between an “A” country and a “B” country are created such that the train lines in the “A” country are created by the railway company in the “A” country, and the train lines in the “B” country are created by the railway company in the “B” country, and respective train lines are coupled. In train diagram lines thus created, the train lines may not be sufficiently adjusted. Waiting is generated where rail way tracks are crossed, and the trains may be significantly delayed. Thus, the supervisor according to the third embodiment is a new user installed to unify the management of a plurality of cross-border train lines created by a plurality of companies.
In this way, the train diagram edit system according to the third embodiment offers the following advantages in addition to the advantages offered by the first embodiment by defining the supervisor in the data base unit 102.
(1) Since the supervisor has an authority to edit the train lines separately created by a plurality of the companies, the trains can be mutually operated effectively among train lines by different companies.
(2) When one train enters from the “A” country to the “B” country as described above, the train diagrams of the “A” country to the “B” country can be collectively managed. Also, when the trains run crossing railway tracks, the supervisor can detect and modify a plan that the trains will pass the crossing railway tracks at the same clock via the diagram edit terminal 3.
(3) Since the supervisor has an authority to edit the train lines created by a plurality of the companies, the supervisor can modify both of the train lines created by the railway company in the “A” country and created by the railway company in the “B” country. In addition, when the train lines are modified by the supervisor, and the predetermined conditions are met, e.g., when the arrival time of the train to the “A” country is earlier than the departure time of the train from the “B” country, the train diagram edit system can couple the train lines based on the authority level of the supervisor similar to the first and second embodiments.
(4) When information about the supervisor who unifies the management of the train lines crossing the companies is held in the authority setting information table 102B and the user information table 102C in the diagram management server 1, the supervisor can edit the train lines and change the creation person even when the business manager is absent.
