Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a route management system capable of visually grasping information on a route at a specified point and surrounding information.

[0002]

2. Description of the Related Art In general, for example, in a command room for centrally managing a railway track network, when an emergency report is given that a trouble such as a fire along a railway line or a track obstruction has occurred, first, a route map of the area, a normal route map, Expand the map, aerial photograph, construction drawings of the section, etc., and keep in touch with the locals, combine the information, grasp the details of the railway, and based on the obtained information, the nearest railway maintenance While contacting public offices such as police stations and fire departments in charge of jurisdiction, the government will issue instructions for evacuation guidance if necessary and take necessary measures such as arranging transfer means.

[0003] As described above, conventionally, when trying to grasp the details of a railway line, a large amount of data is obtained, and based on the information obtained from the information, the situation is imagined and then a countermeasure is determined. There is a disadvantage that it takes a relatively long time to issue a command.

For this reason, various route management systems have recently been proposed which utilize a computer system to display a map image of a route along with necessary information on a monitor so that the situation can be grasped instantaneously.

[0005]

However, the conventional route management system merely displays a map image along the route, an address indicating the location of a public institution, a telephone number, and the like individually. The work of grasping the details of the route along with the combination ultimately had to rely on humans.

[0006] Further, since this system is merely computerized information obtained on the conventional paper, for example, the location of the nearest gate which is an entrance to an elevated line, the gradient of a line, the degree of a curve, and the like. However, it was not possible to grasp the status of the route instantaneously, and it took a certain amount of time to give an accurate instruction.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a route management system capable of instantaneously judging the state of a railway along with a simple operation and determining an accurate instruction in a short time.

[0008]

In order to achieve the above object, a route management system according to the present invention inputs a storage unit for storing video information and track information taken by actual driving, and information indicating a target base point. An input unit, an operation unit that searches the storage unit based on the input base point information and reads and outputs the corresponding image information and track information, and a display unit that displays the image information and the line information output from the operation unit And characterized in that:

In such a configuration, when information indicating a target base point is input from the input unit, the arithmetic unit converts the video information and the line information stored in the storage unit based on the input base point information. Search, read the corresponding video information and track information, and output them to the display unit. The operator visually recognizes the state of the railroad based on the video information displayed on the display unit and the corresponding railroad information.

In this case, it is preferable that the storage unit stores the video information and the track information for each predetermined distance in a database.

When the base information is input from the input section, the arithmetic section reads the video information and the track information before the set distance of the base information and sequentially outputs the information to the display section.

T, a monitor 2a such as a liquid crystal display, a display unit 2 comprising a printer 2b for printing and outputting inspection results, a main storage unit 3 for storing various control programs, and executing a control program stored in the main storage unit 3. And a secondary storage unit 5 such as a hard disk, a CD-ROM, or a DVD for storing information read in the process of executing the control program.

As shown in FIG. 2, the secondary storage unit 5 stores a video information file 5a, a route information file 5b, a peripheral information file 5c, and the like, which are made into a database.

In the video information file 5a, video information for all routes is stored with one frame of video information for each predetermined distance (100 m in the present embodiment) of a railway line to be managed, and a starting point is set. The reference information includes a kilometer information, a code for identifying a route, and the like. still,
In the present embodiment, since there is only one target line, the code for identifying the line can be omitted.

The image information of each frame is an image of both ascending and descending images taken from the vicinity of the driver's cab at the time of actual running of the railroad vehicle. Then, it is possible to visually recognize the status of the route that cannot be easily recognized.

The route information file 5b relates to the route corresponding to the image information, such as the location of the route in the administrative division, the type of structure (viaduct, embankment, etc.), curve information, gradient information, distance information to the adjacent gate, and the like. Information, link information to video information, and the like are stored.

The peripheral information file 5c mainly contains information such as the location of the nearest public office such as a track maintenance station, a power station, a jurisdiction police station, a fire department, etc., corresponding to the video information, and contact information. Information on necessary departments and organizations, link information to video information, and the like are stored. If there is a subway line nearby, the name of the subway line,
The contact information, the name of the nearest station, and the like may be displayed at the same time.

When a kilometer is input from the input unit 1, the arithmetic unit 4 searches the video information file 5a stored in the secondary storage unit 5, and searches the video information file 5a at a position 500 m from the input kilometer. Read the route information and the peripheral information of the route information file 5b and the peripheral information file 5c linked to each other while reading in order from the image information of the adjacent position,

The operator operates an input unit 1 such as a keyboard.
Is operated to input a kilometer in the kilometer input window w1 and press the "Enter" key on the keyboard. Then, the program proceeds to step S2, and the input kilometer (hereinafter, referred to as "input kilometer") ).

This kilometer is entered as an absolute kilometer with reference to the station serving as the starting point of each railway line.
The up route is input with a negative value. In this embodiment, since the route information display processing for one railway line is performed, in step S1, an input of only about a kilometer is awaited, but a system capable of displaying a plurality of route information is provided. If there is, first, a route to be displayed is selected and specified, and then a kilometer is input.

Then, the video information file 5a, the route information file 5b, and the peripheral information file 5c stored in the secondary storage unit 5 are searched, and 500 m before the input kilometer,
That is, the information is sequentially read from the information five frames before, and in step S4, each information is synthesized, and the synthesized image signal is
Output to a.
