Match the map with the map, the current system diagram, etc., the location of the faulty equipment, the location where an abnormality such as a fire along the line (the location of the equipment to be inspected in daily maintenance / management work, etc.), etc. Identify the site location.

  However, at present, the corresponding equipment, etc. can be found and printed from a long equipment system diagram or current system diagram, etc. It took a long time to find the gates and railroad crossings to enter the track from the roads around the site in order to reach the site of the equipment, etc. For this reason, it may take a considerable amount of time to prepare for the site. In addition, if there is a maintenance worker with land intuition, it is possible to rush to the site quickly depending on the experience, but if it is not a maintenance worker with land intuition, it will still take time at the preparation stage. End up.

  In addition, for example, when working at night, if there is no light near the site in the middle of the station and there is no light, it is difficult to see the feet of maintenance workers, or there are protrusions such as trees and equipment near the site. In many cases, it is not easy for maintenance workers to work safely.

  The present invention has been made in view of the above-mentioned problems, and when maintenance workers perform maintenance and management of railways, the maintenance workers can be promptly provided with necessary information. It is an object of the present invention to provide a maintenance work support system that makes it possible to work safely.

In order to solve the above-mentioned problem, the maintenance work support system of the present invention includes:
A portable terminal carried by a maintenance worker;
A server including a position conversion engine capable of converting the input position information into information of a plurality of types of positions including a kilometer, and

It is a figure showing the example of a display on the display screen of a portable terminal, the position which the maintenance worker input, equipment, etc. It is a figure showing the example of the abnormal location photograph displayed on the display screen of a portable terminal.

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

[Configuration of maintenance work support system]
FIG. 1 is a diagram illustrating 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 a tablet terminal such as iPad (registered trademark), for example, and includes a display screen 11. Each maintenance worker W1, W2,... (Hereinafter generally referred to as maintenance worker W) carries the portable terminal 10 respectively. In addition, the mobile terminal 10 incorporates positioning means 12 such as GPS (Global Positioning System) and further has necessary functions such as a character input function, a communication function, a photographing function, and a recording function.

  In addition, when a predetermined operation is performed by the maintenance worker W, the mobile terminal 10 displays a list L of route names on the display screen 11 as shown in FIG. The user can select and input a route name by touching a predetermined route name from the list L. When a route name is selected, the mobile terminal 10 displays a numeric keypad (not shown) on the display screen 11. And the maintenance worker W can input about kilometer by touching a numeric keypad.

  The server 20 is configured by a cloud server, for example, and includes a position conversion engine 21. As shown in FIG. 3, the position conversion engine 21 receives position information in the form of, for example, latitude / longitude (for example, GPS information), an address, or a route name and kilometer as described above, or a station name. No matter what type of equipment information such as the name of the structure or the like is input, it will be converted into information on the location of multiple types of forms such as the corresponding latitude / longitude, address, route name and distance, and equipment information. Each is converted and output.

  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 of various system diagrams such as equipment system diagrams and current system diagrams are stored, and information on each facility (particularly gates and railroad crossings). Etc.), a facility database 33 in which information on facilities that can be entered into the track is stored.

  In the present embodiment, the database 30 further includes an abnormal part medical record database 34 including an abnormal part photo database 341 in which information on abnormal part pictures is stored, an abnormal part audio database 342 in which information on abnormal part audio is stored, and the like. Although it is included, this point will be described later. Although not shown in the drawings, for example, it is possible to provide a database in which a manual for restoring each facility (specifications of the manufacturer of the facility) is stored.

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

  Since the server 20 includes the position conversion engine 21 as described above, whatever type of position information is transmitted to the server 20 as described below (that is, the position information is the latitude / longitude, The position conversion engine 21 converts the position information into position information of all forms, regardless of the address, route name and kilometer, facility information, etc. Therefore, when the server 20 searches the database 30 as described below, it is possible to accurately search each piece of information regardless of the form of position information associated with the information stored in each database. Is possible.

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

  And the server 20 searches each database of the database 30, and the information (map, equipment, etc.) matched with the information of the position within the predetermined range from the position converted by the position conversion engine 21 Is transmitted to the mobile terminal 10. And the portable terminal 10 alert | reports the said information transmitted from the server 20. FIG.

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

[Case 1]
For example, the maintenance worker W operates the mobile terminal 10 to install the facility information such as the facility name of the facility that is subject to maintenance in daily maintenance / management work or the facility that has been informed of abnormality from the operation command. And a route name where the equipment is provided and location information such as kilometer (or latitude / longitude, address, etc.). When receiving the above input, the mobile terminal 10 transmits information on the input position 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 in the database 30, and information (map information) associated with position information within a predetermined range (for example, within 10 km) from the position converted by the position conversion engine 21. And the facility information, etc.) are read, and the read information (including the information on the associated location) is transmitted to the mobile terminal 10 together with the map information of the portion including the location converted by the location conversion engine 21.

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

  In addition, the portable terminal 10 also adds marks I1, I2,... Representing each information on the map M based on, for example, predetermined information on the map M based on the position information associated with each transmitted information. It is displayed in shape, color, size, etc. At that time, for example, a mark of a facility (for example, a gate mark I1 or a crossing mark I3) such as a gate or a railroad crossing that can enter the track from a road around the site is a mark of other equipment. It can be configured to display in different shapes, colors, sizes, and the like.

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

  In this way, the mobile terminal 10 automatically displays the map M on the display screen 11, and on the map M, the position P input by the maintenance worker W and information on each facility in the vicinity thereof. By configuring so as to display I1, I2,..., The maintenance worker W simply inputs the position P of the facility to be maintained from now on, and the facility P (marks I1, I2) in the vicinity thereof. ,...) Can be displayed on the map M.

  Therefore, the maintenance worker W simply looks at the display on the map M displayed on the display screen 11, and the position P input by the maintenance worker W (that is, abnormality or the like from the target equipment or operation command to be maintained from now on). It is possible to clearly and easily recognize the position on the map M of the facility) and the position of the facilities I1, I2,.

  Further, when the maintenance worker W inputs the position P on the mobile terminal 10, the server 20 quickly determines the facilities I1, I2,... In the vicinity of the input position P. Therefore, when the maintenance worker W inputs the position P to the mobile terminal 10, such 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 preparation 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, the maintenance worker W searches and prints out a long facility system diagram, a current system diagram, etc. before going to the site, or is described in about a kilometer track. To find the actual location of the equipment, etc. that are located on the map, or to find a gate or railroad crossing to enter the track from the road around the site to reach the site of the equipment, etc. Can be omitted.

  Furthermore, 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 based on the curve of the track near the position P. It is also possible to accurately determine in advance how many members to make.

  When the maintenance worker W performs a predetermined operation on the mobile terminal 10, the server 20 reads information on various system diagrams such as an equipment system diagram and a current system diagram from the system diagram database 32, 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. Need not be opened, and everything can be performed on the portable terminal 10.

  Further, when the equipment marks I1, I2,... Are displayed on the display screen 11 of the mobile terminal 10 as shown in FIG. 4, although not shown, for example, the equipment marks I1, I2 are omitted. The name of the equipment and the code representing it are displayed in the vicinity of, ..., or the window is opened when the equipment mark I1 etc. is clicked, and necessary information such as the equipment name and description is displayed there. It is also possible to configure so as to.

  Further, the maintenance worker W can display an image related to the equipment such as a street view of the place where the equipment is provided by performing a predetermined operation on the equipment mark I1 or the like. It is also possible to do. If comprised in this way, it will become possible to know in advance, for example, whether there is a space for stopping a car on which the maintenance worker W or the like got on, where the vehicle can enter the track.

  In addition, when the maintenance worker W designates the facility mark I1 by clicking the equipment mark I1, etc., the portable terminal 10 is set to the designated position (in the above case, the position in the real space such as the equipment mark I1). The route from the current location to the designated position can be displayed based on the current location of the mobile terminal 10 measured by the positioning means 12.

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

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

  For example, as shown in FIG. 1, information on abnormal part photographs is stored in the abnormal part photograph database 341 of the abnormal part medical record database 34, or information on abnormal part voices is stored in the abnormal part voice database 342 (both are location information). ) Is stored, for example, when position information is transmitted from the mobile terminal 10 carried by the maintenance worker W who has entered the track, the server 20 transmits the information. If there is information on the above abnormal part photo or abnormal part sound within a predetermined range from the position of the mobile terminal 10 (in this case, for example, 10 m, etc.), the information is read and the read information is automatically transmitted to the mobile terminal 10. (Ie, even if there is no operation of the maintenance worker W).

  In this case, the abnormal location is, for example, a location where there are projections such as tree branches or standing piles in the track as shown in FIG. 5, a location under construction in the track, or in the track. This is a place where maintenance workers W and others need attention, such as a place where there is no evacuation place. Further, the information on the abnormal part photo represents information on the photograph F obtained by photographing such an abnormal part (see, for example, FIG. 5), and the information on the abnormal part voice is a sound relating to such an abnormal part (that is, the abnormal part, for example, This represents information of the recorded sound (explained by the maintenance worker W and the like).

  And the portable terminal 10 will automatically display the abnormal part photograph F on the display screen 11, if the information of the abnormal part photograph F and the abnormal part audio | voice is transmitted from the server 20, or an abnormal part audio | voice automatically. Or play back. 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 part photograph F and the abnormal part sound).

  If configured as described above, for example, if there is an abnormal part as described above within 10 m from the maintenance worker W heading to the work site in order to perform maintenance work at night, for example, the maintenance worker Even if W does not operate the mobile terminal 10, the abnormal part photo F is automatically displayed on the display screen 11 of the mobile terminal 10 as described above, or the abnormal part sound is automatically reproduced.

  For this reason, for example, when the maintenance worker W is heading for a site on a dark track, even if the abnormal location cannot be seen and the abnormal location is not noticed, the abnormal location photo F is displayed on the mobile terminal 10. Since it is automatically displayed or the abnormal part sound is automatically reproduced, the maintenance worker W can accurately recognize that there is an abnormal part nearby. At the same time, it is possible to accurately recognize what kind of abnormal part exists.

  Therefore, properly avoid the equipment such as tree branches and standing piles protruding from the track, avoid the place under construction, or stop where there is no evacuation place and confirm that the train does not come through It is possible to take appropriate measures such as performing maintenance, and it becomes possible for maintenance workers W and others to go to the site safely or to recognize any abnormal parts near the site accurately, and to perform maintenance work. Personnel W and the like can work safely.

  In this case, when displaying the abnormal part photograph F on the mobile terminal 10, the mobile terminal 10 can be configured to sound a warning sound. The mobile terminal 10 may be configured to vibrate. In this way, by generating the sound by reproducing the abnormal part sound or sounding the warning sound on the mobile terminal 10, when there is an abnormal part in the vicinity, the maintenance worker W or the like can appropriately receive the attention. It can be aroused.

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

  Therefore, in such a case, in the present embodiment, since the portable terminal 10 has the photographing function and the recording function as described above, the abnormal part is photographed by the portable terminal 10 or the maintenance worker W The abnormal part is explained verbally, the voice is recorded in the portable terminal 10, the photograph and the voice are transmitted to the server 20, and the abnormal part photo database 341 and the abnormal part voice database are used as the abnormal part photo F and the abnormal part voice. 342 can be configured to accumulate.

  If comprised in this way, when an abnormal location is newly discovered, it will become possible to register it in a database and to update it at any time. Also, for example, when the abnormal part photo F is displayed on the portable terminal 10 or the abnormal part sound is reproduced, but the abnormal part is improved and is no longer an abnormal part, the maintenance worker W is It is also possible to configure the server 20 to delete the photo and audio information relating to the abnormal location from the abnormal location photo database 341 and the abnormal location audio database 342 by operating the terminal 10.

  In this embodiment, the abnormal part medical record database 34 shown in FIG. 1 manages what information is stored in the abnormal part photograph database 341 and the abnormal part voice database 342 described above. In addition, in the abnormal part medical record database 34, for example, the type and name of equipment registered in the abnormal part photo database 341 or the abnormal part voice database 342 as an abnormal part, the installation location (that is, latitude / longitude, etc.), emergency Information (according to the degree of importance of information, representing the range of personnel such as employees who share the information accumulated in the abnormal part photo database 341 and the abnormal part voice database 342).

[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, they can quickly provide necessary information to the maintenance workers W and the like. In addition, the maintenance workers W and the like can perform maintenance work safely.

  Therefore, when maintenance workers W perform daily maintenance and management work, or when an abnormality occurs and a contact is received from an operation command, a long facility system diagram or The server 20 eliminates the need to search for the site from the current system diagram, print it, specify the location of the site by tracing the map, and search for gates and railroad crossings to enter the track. Since necessary information is provided promptly, maintenance work can be performed promptly on site.

  In addition, when maintenance work is performed 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 photo F is automatically displayed on the mobile terminal 10. Displayed abnormally or the sound of abnormal parts is automatically played back. Therefore, the maintenance worker W can accurately recognize that there is an abnormal part nearby, and can accurately recognize what kind of abnormal part is present, and can perform maintenance work safely.

  Needless to say, the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the gist of the present invention.
