DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram for explaining the system configuration of the present invention.
The track maintenance work support system 10 includes a maintenance work plan diagram server 11, a diamond display device 12, a central device having an operation status display server 13, a maintenance zone terminal 15 connected to the central device via a telephone line 14, The mobile terminal 17 is connected to the operation status display server 13 via a dedicated line 16, and each device is connected to the network via a LAN and an ISDN line. In addition, information transmission from the operation status display server 13 to the mobile terminal 17 uses a cellular phone line by packet communication, and a web page created by HTML widely used on the Internet is displayed on the terminal screen by the browser function of the mobile terminal. Depending on the display method.
[0008]
The maintenance schedule plan server 11 of the central unit receives train schedule data from the integrated transportation system 20 that has all the data on which the train schedule is based in the implementation schedule (basic schedule + extraordinary schedule) state. It has a function of supplying diagram data in response to a request from the terminal 15 and collectively managing a maintenance work plan input at the maintenance area terminal.
[0009]
The maintenance area terminal 15 receives the train data of the transport comprehensive system 20 from the maintenance work plan diagram server 11, displays the diamond on the CRT screen, registers the work plan, and confirms the train of the transport comprehensive system two days before the work is performed. It has a function to check the validity of the maintenance work by checking with the diamond data.
[0010]
The diamond display device 12 is installed in a command room or the like for operation management, displays the input maintenance work plan and the state of execution of the maintenance work, and instructs (operates) based on a request from the local line closure manager. In addition to displaying the handling time of the “line closing” which is an operation switch of the traffic light to the manager, the command is for inputting approval information.
[0011]
The operation status display server 13 receives the train operation status data from the central device, and provides the train operation status in response to a request from the mobile terminal via the mobile phone line. In addition, it relays information transmission from the mobile terminal to the diagram display device at the time of the application for the start of the track closing work and the completion report.
[0012]
FIG. 2 is a diagram for explaining the creation of a maintenance work plan at the maintenance area terminal.
The maintenance work plan downloads the train schedule data necessary for the work plan possessed by the transportation system 10 through the maintenance work plan diagram server 11, and on the CRT screen of the maintenance area terminal composed of a general-purpose personal computer based on the data. Is displayed in the train diagram format. In the figure, the horizontal axis indicates the time, and the vertical axis indicates the train passing position. The lower right is a down train, the upper right is an up train, and when entering a maintenance work plan, a stop where the maintenance work plan is to be performed on this CRT screen. The premises or between stops (B station in the figure) and between trains (T1 to T2 in the figure) are designated with a mouse. When specified with the mouse, the stop area or between stops and between trains are automatically displayed on the plan input screen, and a work plan is automatically created when necessary items are input. In this case, the start train and the end train are automatically recognized, and the correctness of the train interval is automatically checked. In the example shown in the figure, there is no train passing through the down lane, so there is no competition with the train for the down lane.
[0013]
FIG. 3 is a diagram for explaining a train interval check method in the present system.
In this check method, a method of matching the scheduled work start time and scheduled work end time of the maintenance work plan with the time of the train line is employed. In other words, looking at the maintenance work plan (1) for the yard (station 2) in the figure and the maintenance work plan (2) between the stops (station 5 in the figure), the presence check of the train (A) before starting work is The planned start time of the planned work is converted to the coordinates of points a and b on the screen of the maintenance area terminal, and there is a train line to the left from the pixel value (coordinate value), and the train line is specified Check if it is a short train. The same applies to trains that have completed planned work. Check the correctness of the train interval by converting the scheduled work end time to the coordinates of point c and point d on the screen and searching for the train line to the right from each point. Do it automatically.
[0014]
If the start train (A) and end train (B) of the maintenance work automatically selected by the mouse are different from those intended by the creator, it can be selected manually. In addition, the above method automatically checks that there is no conflict of train competition between the train schedule and the maintenance work plan. In addition, in order to prevent the train from entering the maintenance work location, the maintenance work plan and the train operation are also checked for conflicts. This method is performed on graphic data in the same way as the train interval check.
[0015]
FIG. 4 is a diagram for explaining a train competition check method in this system.
The presence or absence of a train (C train) that is operated during the maintenance work plan (1) between the stops (station 2 in the figure) indicates that the scheduled work start time is determined from the graphic coordinates a and b on the right. Search for the train line up to point c and point d in the direction (convert the train line time to coordinates on the screen and search if the coordinate value is between points a, b and c, and d) Confirm by.
[0016]
In this way, the start train and the end train are automatically recognized to check whether the train is correct or not, and then the train conflict is checked to input the maintenance work plan. Further, it is checked whether or not the maintenance work planned when the maintenance work plan input is completed conflicts with the maintenance work in other maintenance districts. If there is a conflict, an alarm and a list of conflicting work are displayed. If there is competing work, the contents can be confirmed on the same screen, and it is possible to register after adjusting between the responsible persons.
[0017]
Check work conflicts by specifying the “work location / construction date” when entering the work plan, so that the work schedule data of the maintenance schedule and other maintenance districts will be received from the maintenance work plan diagram server 11 and the received data will be self-maintained. When writing the maintenance work plan written in the memory or database in the ward terminal and writing the input maintenance work plan on its own terminal, the work location and the train interval are checked. It is judged and displayed. Since maintenance work is generally performed continuously at the same location, use the copy function of the personal computer to specify the work date and time for maintenance work plans for the same location and time span over multiple days. It also has a function to check the scheduled train schedule for the day and register the work plan in a lump.
[0018]
After the work plan is registered in this way, automatic diamond check and approval are performed by a fixed diamond, which will be described.
FIG. 5 is a diagram for explaining automatic diamond check by a fixed diamond.
Conventionally, the competition check between the train schedule and the work plan based on the reading of the commander is checked on the system by superimposing the confirmed schedule (train information) of the integrated transportation system and the registered work plan at the maintenance area terminal. In other words, a final check is made between the work plan and the confirmed schedule two days before the construction date (train operation day) when the train schedule is confirmed, and the work plan is approved if there is no conflict between the train schedule and the maintenance work. Executed as a real work.
[0019]
The relationship between the confirmed train schedule received from the maintenance work plan server 11 and the train interval of the registered maintenance work plan is checked by superimposing data, and if the train operation and maintenance work do not conflict, automatic The maintenance work plan is displayed in green on the maintenance area terminal screen to notify the creator that it has been approved. In addition, as shown by the broken line in FIG. 5, when a temporary train (dashed line in the figure) competing with it is set after the work plan registration, the work is automatically extracted, and the work plan is unapproved, The work plan is displayed in red on the CRT screen of the maintenance area terminal, and the creator is notified that the plan has been disapproved. The maintenance work plan that has not been approved can be changed and input, for example, by shortening the time.
[0020]
This automatic diamond check is performed once a day with a confirmation schedule and a maintenance work plan, and the timing is automatically performed when the maintenance area terminal power is turned on. When the power of the maintenance area terminal is continuously turned on, an automatic diamond check is executed at a fixed time. In addition, in order to distinguish between maintenance work plans that have completed automatic diamond check with the fixed schedule and maintenance work plans that have not been completed, a flag is set in the system, and both are identified by the maintenance zone terminal and the maintenance work plan diagram server. Is going.
[0021]
FIG. 6 is a diagram for explaining a work start application / end report by the mobile terminal at the work site.
The track maintenance work planned by the maintenance area terminal is displayed in a diamond format on the CRT screen of the diamond display device 12 installed in the command room after the diamond check with the fixed diamond is completed. For example, when applying for a work start, touch the maintenance work plan displayed on the screen of the mobile terminal and send a line closing start, the work contents will be displayed on the diagram display device and an alarm will be generated, After the staff closes the line of the work section and makes necessary train restraint arrangements such as handling, the work start procedure is executed by inputting the approval number on the screen of the diagram display device and approving the work. On the screen of the mobile device, after sending the line closing start, the handling of the lever is displayed until the work approval is performed, and when the work approval is performed, the content of the start approval is displayed on the screen of the mobile device, The procedure for starting work is completed. The procedure is the same for the end of work.
[0022]
On the CRT screen of the diamond display device in the command room, the work mark changes to yellow, red, and green depending on whether the work is started, during work, or finished, and the plan P1 in FIG. 6 is finished in green and the plan P2 is yellow. Thus, before starting work, the plan P3 indicates work in red. In this way, by displaying the work marks in different colors according to the start of work, during work, and at the end of work, the status of track maintenance work can be grasped in real time in the command room. Centralized management is possible.
[0023]
【The invention's effect】
As described above, according to the present invention, by systemizing the process from the planning to the implementation of the track maintenance work, the time required for the track maintenance work procedure can be greatly shortened and the work efficiency can be improved. It is possible to significantly improve the safety of track maintenance by eliminating errors.
