Description

The present invention relates to a maintenance work support system, and more particularly to a railway track maintenance work support system.

Maintenance workers involved in railway maintenance and management rush to the site when an abnormality such as an equipment failure or a fire along the railway line occurs, and perform maintenance work such as repair or replacement of the failed equipment. As a system for supporting maintenance work, for example, as described in Patent Document 1, a maintenance worker may enter a place where a maintenance worker or the like is performing maintenance work or the like. A track maintenance work support system is known to prevent accidents resulting in death or injury.

By the way, the same applies to daily maintenance and management work, but for example, when an abnormality occurs as described above, when a contact is received from the operation command, the maintenance workers first go to the equipment system before going to the site. By comparing the map with the figure or the display system diagram, the position of the failed equipment or the position where an abnormality such as a fire along the railway line occurred (the position of the equipment to be inspected in daily maintenance and management work), that is, Identify the location of the site.

However, under the present circumstances, the relevant equipment, etc. can be found from long equipment system diagrams, actual system diagrams, etc. and printed, or the actual location of the equipment, etc. described in the railroad crossing kilometers can be mapped. It took time to identify by tracing and to search for gates, railroad crossings, etc. to enter the track from the road around the site in order to reach the site of the equipment. Therefore, it may take a considerable amount of time to prepare for the site. Also, if there is a maintenance worker who has a good sense of land, it is possible to quickly rush to the site depending on that experience, but if it is not a maintenance worker who has a good sense of land, it still takes time in the preparation stage. It ends up.

Also, for example, when working at night, if there is no lighting near the site in the middle of the station and it is dark, it may be difficult to see the feet of maintenance workers, or protrusions such as trees and equipment near the site may appear. In many cases, it is not easy for maintenance workers to work safely because they cannot see it.

The present invention has been made in view of the above problems, and when the maintenance workers perform maintenance and management of the railway, the maintenance workers are provided with necessary information promptly, and the maintenance workers and the like. The purpose is to provide a maintenance work support system that enables people to work safely.

Hereinafter, embodiments of the maintenance work support system according to the present invention will be described with reference to the drawings. However, the scope of the present invention is not limited to the following examples.

[About the configuration of the maintenance work support system]
FIG. 1 is a diagram showing a configuration of a maintenance work support system according to the present embodiment. In the present embodiment, the maintenance work support system 1 includes a mobile terminal 10, a server 20, and various databases 30.

The mobile terminal 10 is composed of, for example, a tablet terminal such as an iPad (registered trademark), and includes a display screen 11. Then, each maintenance worker W1, W2, ... (hereinafter, generally referred to as a maintenance worker W) carries the mobile terminal 10. Further, the mobile terminal 10 has a built-in positioning means 12 such as GPS (Global Positioning System), and further has necessary functions such as a character input function, a communication function, a shooting function, and a recording function.

Further, when the maintenance worker W performs a predetermined operation on the mobile terminal 10, the maintenance worker W displays a list L of line names on the display screen 11 as shown in FIG. Can select and input a route name by touching a predetermined route name from the list L. Further, when the route name is selected, the mobile terminal 10 displays a numeric keypad or the like (not shown) on the display screen 11. Then, the maintenance worker W can input the kilometer by touching the numeric keypad or the like.

The server 20 is composed of, for example, a cloud-type server, and includes a position conversion engine 21. As shown in FIG. 3, the position conversion engine 21 inputs position information in the form of, for example, latitude / longitude (for example, GPS information) or address, or as described above, a line name and a kilometer, or a station name. Regardless of the form of equipment information such as the name of the structure or the name of the structure, it will be used as information on the position of predetermined multiple types such as the corresponding latitude / longitude, address, route name and kilometer, equipment information, etc. Each is converted and output.

Further, as shown in FIG. 1, various databases 30 are connected to the server 20. The database 30 includes, for example, a map database 31 in which map information is accumulated, a system diagram database 32 in which information on various system diagrams such as equipment system diagrams and actual system diagrams is accumulated, and information on each facility (particularly gates and railroad crossings). Information on equipment that can enter the line such as) is included in the equipment database 33.

In the present embodiment, the database 30 further includes an abnormal location chart database 34 including an abnormal location photo database 341 in which information on abnormal location photographs is accumulated, an abnormal location audio database 342 in which information on abnormal location audio is accumulated, and the like. It is included, but this point will be explained later. Further, although not shown, for example, it is possible to configure the database to include a manual (specifications of the manufacturer of the equipment, etc.) for restoring each equipment.

Further, in the present embodiment, each information stored in each of the above databases is position information of a plurality of types of forms that can be converted by the position conversion engine 21 (that is, latitude / longitude, address, route name and kilometer, etc.). ) Is associated with the position information in any of the forms.

Since the server 20 includes the position conversion engine 21 as described above, no matter what form of position information is transmitted to the server 20 as described below (that is, the position information is latitude / longitude, The position conversion engine 21 converts the position information into all forms of position information (regardless of the form such as address, route name and kilometer, equipment information, etc.). Therefore, when the server 20 searches the database 30 as described below, the information stored in each database should be accurately searched regardless of the form of the position information. Is possible.

[Processing on servers and mobile terminals]
On the other hand, for example, when the maintenance worker W inputs the position information on the mobile terminal 10 by inputting the route name and the kilometer as described above, and the input position information is transmitted, the server 20 inputs the position information into the position conversion engine 21 and converts the position information into a plurality of types of position information. Further, even when the positioning means 12 built in the mobile terminal 10 automatically positions the position of the mobile terminal 10 and the information on the position of the positioned mobile terminal 10 is transmitted, the server 20 also positions the position. The information of the position is input to the conversion engine 21 and converted into the information of the positions of a plurality of types.

Then, the server 20 searches each database of the database 30, and the information associated with the information of the position within a predetermined range from the position converted by the position conversion engine 21 (information such as a map and equipment). Is read and transmitted to the mobile terminal 10. Then, the mobile terminal 10 is adapted to notify the information transmitted from the server 20.

[Action]
Next, the operation of the maintenance work support system 1 according to the present embodiment will be described.

[Case 1]
For example, the maintenance worker W operates the mobile terminal 10 to perform equipment information such as the equipment name of the equipment to be maintained in daily maintenance / management work or the equipment to which an abnormality or the like is notified from the operation command. And the location information such as the line name and kilometer (or latitude / longitude, address, etc.) where the equipment is installed. Upon receiving the above input, the mobile terminal 10 transmits the input position information to the server 20.

When the position information input from the mobile terminal 10 is transmitted, the server 20 inputs the position information to the position conversion engine 21 and converts the position information into a plurality of types of position information. Then, the server 20 searches each database of the database 30, and the information (map information) associated with the information of the position within a predetermined range (for example, within 10 km) from the position converted by the position conversion engine 21. , Equipment information, etc.), and the read information (including the associated position information) is transmitted to the mobile terminal 10 together with the map information of the portion including the position converted by the position conversion engine 21.

When the mobile terminal 10 transmits the map information and the read information from the server 20, first, as shown in FIG. 4, a map including the position is displayed on the display screen 11 based on the transmitted map information. Display M. In this case, the mobile terminal 10 displays, for example, the position P corresponding to the position information (for example, the route name and the kilometer) input by the maintenance worker W in an easy-to-see state with a pin on the map M.

Further, the mobile terminal 10 also puts marks I1, I2, ... Representing each information on the map M based on the information of the position associated with each transmitted information, for example, predetermined. It is designed to be displayed by shape, color, size, etc. At that time, for example, the mark of equipment such as a gate or railroad crossing that allows entry into the track from the road around the site (for example, the mark I1 of the gate or the mark I3 of the railroad crossing) is used as the mark of other equipment. It can be configured to be displayed in different shapes, colors, sizes, and the like.

In this way, the mobile terminal 10 notifies the maintenance worker W of the information transmitted from the server 20 (that is, the equipment information I1, I2, ... And the map information in the above case). ..

Then, in this way, the mobile terminal 10 automatically displays the map M on the display screen 11, and on the map M, along with the position P input by the maintenance worker W, information on each facility in the vicinity thereof. By configuring to display I1, I2, ..., The maintenance worker W can simply input the position P of the equipment to be maintained or the like from now on, and the equipment (marks I1, I2) in the position P or in the vicinity thereof. , ...) can be displayed on the map M.

Therefore, the maintenance worker W simply sees the display on the map M displayed on the display screen 11, and the position P input by the maintenance worker W (that is, an abnormality from the equipment to be maintained or an operation command from now on, etc.) It is possible to clearly and easily recognize the position of the equipment (equipment that has been contacted) on the map M and what equipments I1, I2, ... Are located in the vicinity thereof.

Further, when the maintenance worker W inputs the position P on the mobile terminal 10, the server 20 quickly finds out the equipments I1, I2, ..., Etc. in the vicinity of the input position P. Therefore, when the maintenance worker W inputs the position P to the mobile terminal 10, the information is displayed on the display screen 11 of the mobile terminal 10 in a short time.

Therefore, the maintenance worker W can perform the preparatory work for the maintenance work very quickly (that is, in a short period of time). In addition, as in the case of the current situation described above, before going to the site, the maintenance worker W finds out from a long equipment system diagram, a display system diagram, etc. and prints it, or describes it by the track kilometer. The trouble of identifying the actual location of the equipment, etc. by tracing the map, and searching for gates, railroad crossings, etc. to enter the track from the road around the site in order to reach the site of the equipment, etc. Can be omitted.

Further, since the position P input by the maintenance worker W is displayed on the map M displayed on the display screen 11 of the mobile terminal 10, the train guard is watched based on the bending condition of the railroad track near the position P. It is also possible to accurately determine in advance how many members will be used.

When the maintenance worker W performs a predetermined operation on the mobile terminal 10, the server 20 can read information on various system diagrams such as an equipment system diagram and a display system diagram from the system diagram database 32, or perform other operations. By reading the manual from the database and transmitting it to the mobile terminal 10, the maintenance worker W can display and view them on the display screen 11 of the mobile terminal 10, and can actually see a long equipment system diagram or the like. There is no need to open, and everything can be done on the mobile terminal 10.

Further, when the equipment marks I1, I2, ... The equipment name and the code representing it are displayed in the vicinity of, ..., or the window is configured to open when the equipment mark I1 etc. is clicked, and necessary information such as the equipment name and explanation is displayed there. It is also possible to configure it to do so.

Further, the maintenance worker W can perform a predetermined operation on the mark I1 of the equipment to display an image related to the equipment such as a street view of the place where the equipment is installed. It is also possible to do. With this configuration, it is possible to know in advance, for example, whether there is a space for the maintenance worker W or the like to stop the vehicle, and where the vehicle can enter the track.

Further, when the maintenance worker W specifies by clicking the mark I1 or the like of the equipment, the mobile terminal 10 is assigned to the designated position (in the above case, the position of the mark I1 or the like of the equipment in the real space). It is also possible to configure the positioning means 12 to display the route from the current location to the designated position based on the current location of the mobile terminal 10 positioned.

In addition, acquisition of materials and data necessary for grasping the situation at the site mentioned above, that is, display of various system diagrams and manuals on the mobile terminal 10, display of necessary information such as equipment mark I1, street view, etc. Processing such as displaying images related to the equipment and displaying the route from the current location to the destination does not necessarily have to be performed at the stage of preparation for maintenance work, for example, maintenance workers W and others can perform the processing while moving to the site. Is.

[Case 2]
On the other hand, in the present embodiment, the server 20 is not only when the maintenance worker W inputs the information of the position P by inputting the route name and the kilometer on the mobile terminal 10 as described above, but also described above. As described above, when the positioning means 12 built in the mobile terminal 10 automatically positions the position of the mobile terminal 10 and the information on the position of the positioned mobile terminal 10 is transmitted, the same procedure as described above is performed. , Each database of the database 30 is searched, and the information (information such as a map and equipment) associated with the information of the position within a predetermined range from the position is read out and transmitted to the mobile terminal 10.

For example, as shown in FIG. 1, the information of the abnormal part photograph is accumulated in the abnormal part photograph database 341 of the abnormal part chart database 34, and the information of the abnormal part voice is stored in the abnormal part voice database 342 (both are position information). When the location information is transmitted from the mobile terminal 10 carried by the maintenance worker W who has entered the line, for example, the server 20 is transmitted. If there is information on the above-mentioned abnormal part photo or abnormal part voice within a predetermined range (for example, 10 m in this case) from the position of the mobile terminal 10 that has arrived, the information is read out and the read information is automatically transmitted to the mobile terminal 10. (That is, even if there is no operation of the maintenance worker W).

In this case, the abnormal location is, for example, a location in the track where there are protrusions such as tree branches or equipment such as vertical stakes, a location in the track under construction, or in the track as shown in FIG. A place that requires attention by maintenance workers W and others, such as a place where there is no evacuation place. Further, the information of the abnormal part photograph represents the information of the photograph F in which such an abnormal part is taken (see, for example, FIG. 5), and the information of the abnormal part sound is the sound related to such an abnormal part (that is, for example, the abnormal part). It represents the information of the recorded voice) in which the maintenance worker W et al. Explained the state and the like.

Then, when the information of the abnormal part photo F and the abnormal part voice is transmitted from the server 20, the mobile terminal 10 automatically displays the abnormal part photo F on the display screen 11 or automatically displays the abnormal part voice. To play. In this way, the mobile terminal 10 notifies the maintenance worker W of the information transmitted from the server 20 (that is, in this case, the abnormal portion photograph F and the abnormal portion voice).

Then, with the above configuration, for example, if there is an abnormal part as described above within 10 m from the maintenance worker W who is heading to the site for maintenance work at night, the maintenance worker. Even if W does not operate the mobile terminal 10, the abnormal portion photograph F is automatically displayed on the display screen 11 of the mobile terminal 10 or the abnormal portion voice is automatically reproduced as described above.

Therefore, for example, when the maintenance worker W is heading to the site in a dark railroad track, even if the abnormal part cannot be visually observed and the abnormal part is not noticed, the abnormal part photograph F is displayed on the mobile terminal 10. Since it is automatically displayed or the abnormal part sound is automatically played back, the maintenance worker W can accurately recognize that there is an abnormal part nearby. At the same time, it becomes possible to accurately recognize what kind of abnormal part is present.

Therefore, avoid equipment such as tree branches and stakes protruding into the track, avoid places under construction, or stop once and pass after confirming that trains do not come in places where there is no evacuation area. It becomes possible to take appropriate measures such as taking appropriate measures, and it becomes possible for maintenance workers W and others to safely head to the site, and if there is an abnormal part near the site, it becomes possible to accurately recognize it, and maintenance work. Members W and others can work safely.

In this case, it is also possible to configure the mobile terminal 10 to sound a warning sound when displaying the abnormal portion photograph F on the mobile terminal 10. The mobile terminal 10 may be configured to vibrate. Then, by generating the voice by playing the voice of the abnormal portion or sounding the warning sound on the mobile terminal 10 in this way, when there is an abnormal portion in the vicinity, the maintenance worker W and others are appropriately warned. It becomes possible to arouse.

Further, the maintenance workers W and others found an abnormal part on the way to the site or near the site, but if it is not displayed on the mobile terminal 10, the information of the abnormal part is stored in the database 30. It can be seen that it is not stored in the abnormal part photo database 341 or the abnormal part voice database 342.

Therefore, in such a case, in the present embodiment, since the mobile terminal 10 has a shooting function and a recording function as described above, the mobile terminal 10 may shoot the abnormal portion or the maintenance worker W may take a picture. The abnormal part is verbally explained, the mobile terminal 10 is made to record a voice, and the photograph and the voice are transmitted to the server 20, and the abnormal part photo F and the abnormal part voice are the abnormal part photo database 341 and the abnormal part voice database. It can be configured to accumulate in 342.

With this configuration, when a new abnormal part is found, it can be registered in the database and updated at any time. Further, for example, when the abnormal part photograph F is displayed on the mobile terminal 10 or the abnormal part sound is reproduced, but the abnormal part is improved and the abnormal part is no longer an abnormal part, the maintenance worker W carries it. It is also possible to operate the terminal 10 to configure the server 20 to delete the photo and audio information related to the abnormal location from the abnormal location photo database 341 and the abnormal location audio database 342.

In the present embodiment, the abnormal location chart database 34 shown in FIG. 1 manages what kind of information is stored in the abnormal location photo database 341 and the abnormal location voice database 342. In addition, in the abnormal location chart database 34, for example, the type and name of the equipment registered in the abnormal location photo database 341 and the abnormal location voice database 342 as abnormal locations, the installation location (that is, latitude / longitude, etc.), and emergency. Information such as the degree (that is, the importance of the information is represented, and the range of personnel such as employees who share the information stored in the abnormal location photo database 341 and the abnormal location voice database 342) is accumulated.

[effect]
As described above, according to the maintenance work support system 1 according to the present embodiment, when the maintenance workers W and the like perform maintenance and management of the railway, the maintenance workers W and the like can promptly provide necessary information. At the same time, maintenance workers W and others can safely perform maintenance work.

Therefore, when maintenance workers W and others perform daily maintenance and management work, or when an abnormality occurs and a contact is received from the operation command, a long equipment system diagram is displayed at the preparatory stage before going to the site. The server 20 eliminates the need to search for and print the site from the displayed system diagram, identify the location of the site by following the map, and search for gates, railroad crossings, etc. to enter the track. Since the necessary information is provided promptly, it is possible to quickly rush to the site and perform maintenance work.

Further, in the case of performing maintenance work at night, even if the maintenance worker W is dark and cannot see the abnormal part and does not notice the abnormal part, the abnormal part photograph F is automatically displayed on the mobile terminal 10. Or the abnormal part sound is automatically played. Therefore, the maintenance worker W can accurately recognize that there is an abnormal part in the vicinity, accurately recognize what kind of abnormal part is, and perform the maintenance work safely.

Needless to say, the present invention is not limited to the above-described embodiment and can be appropriately changed as long as it does not deviate from the gist of the present invention.
