Description

The present invention relates to indicator light management system technology used during track closure work.

As a method for preventing tools used during track construction from being left behind, there is a method in which a two-dimensional code is attached to the tool, the two-dimensional code is photographed before work begins, the tool identification information indicated by the two-dimensional code is recognized, and after work is completed, the two-dimensional code is photographed again, the tool identification information indicated by the two-dimensional code is recognized, and the tool identification information recognized before work begins is compared with the tool identification information recognized after work is completed. If there is a discrepancy in the number of tools, the information on the misplaced tools is displayed in a visually understandable manner, making it possible to identify the misplaced tools (for example, Patent Document 1).

JP 2019-016090 A

In the case of Patent Document 1, it is possible to identify tools that have been left behind, but this can only be done after the work has been completed. For example, in the case of large items such as indicator lights used during track closure work carried out at night, or items that are used on the tracks, it is difficult to visually discover tools that have been left behind at night. In addition, indicator lights are particularly suitable for use during the day on cloudy days or thick fog when visibility is poor, but it is difficult to visually discover tools that have been left behind due to poor visibility. Furthermore, even if it were possible to identify tools that have been left behind after the work had been completed, it would not have been possible to prevent a major accident from occurring when the tools are not ready in time for trains to start operating after the work has been completed.

The present invention was made in consideration of the above problems, and relates to technology that enables indicator lights to be reliably retrieved from track closure work.

The present invention relates to a track closure indicator management system with a function to prevent leaving behind, the system comprising: a registration means for registering the track closure indicator, an alert setting means for setting an alert time for each track closure indicator, the alert time being a predetermined time that is determined before or after the scheduled collection time; a collection processing means for determining whether the identification information read by the reading means is stored in the storage means, and determining that the track closure indicator related to the identification information has been collected if it is stored; and a notification means for outputting a notification that the track closure indicator has not been collected when the alert time for the track closure indicator that has not been determined to have been collected by the collection processing means arrives.

The present invention also relates to a portable terminal used for construction work performed by closing railway tracks, and used together with a track closure indicator light having a readable information recording unit affixed thereto in which identification information for identifying an individual is recorded, the portable terminal comprising: reading means for reading the identification information recorded in the information recording unit; storage means for storing the information read by the reading means; scheduled time receiving means for receiving input of time information indicating a scheduled recovery time of the track closure indicator light used for the construction work; registration means for causing the identification information for the track closure indicator light read by the reading means to correspond to the time information for the track closure indicator light received by the scheduled time receiving means and to store the associated information in the storage means; alert setting means for setting an alert time that is a predetermined time that is set before or after the scheduled recovery time and is set for each track closure indicator light; and recovery processing means for determining whether the identification information read by the reading means is stored in the storage means, and determining that the track closure indicator light associated with the identification information has been recovered if it is stored.
The present invention relates to a mobile terminal that is equipped with an alarm means that, when the alert time for a track closure indicator light that has not been determined to have been collected by the collection processing means arrives, outputs an alarm that the track closure indicator light has not been collected.

The present invention also relates to a computer program for operating a mobile terminal which is used in construction work carried out by closing railway tracks, and is used together with a track closure indicator light having a readable information recording unit affixed thereto in which identification information for identifying an individual is recorded, the computer program comprising: a reading process for reading the identification information recorded in the information recording unit by the reading means; a storage process for storing the information read by the reading means in the storage means; a scheduled time receiving process for receiving input of time information indicating a scheduled time for recovery of the track closure indicator light used in the construction work; the identification information read by the reading means is stored in the storage means, and if so, determines whether the identification information read by the reading means is stored in the storage means and determines that the track closure indicator light associated with the identification information has been collected; and, when the alert time for a track closure indicator light that has not been determined to have been collected by the collection process arrives, outputs a notification that the track closure indicator light has not been collected.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
First, an overview of this embodiment will be described.
FIG. 1 is a block diagram of a track-closure indicator light management system 10 with a function to prevent misplacement according to the present embodiment.
As shown in Fig. 1, the track closure indicator light management system 10 with a function to prevent misplacement (hereinafter, may be referred to as this system) of this embodiment at least includes a track closure indicator light 200 to which an information recording unit 230 is attached, and an information processing terminal 100 having a reading unit 110 that reads identification information for identifying an individual track closure indicator light 200 from the information recording unit 230. In addition to the reading unit 110, the information processing terminal 100 includes a memory unit 120, a scheduled time receiving unit 130, a registration unit 140, an alert setting unit 150, a collection processing unit 160, and a notification unit 170. In addition to these, the information processing terminal 100 preferably includes a display unit 180 and a speaker 185.
The track closure indicator light 200 is used for construction work that is carried out by closing a railway track. The track closure indicator light 200 is provided with a light emitting unit 220 for informing people that the track is closed due to construction work, and has a readable information recording unit 230 attached thereto in which identification information that identifies the individual unit is recorded.
The reading unit 110 is a means for reading the identification information recorded in the readable information recording unit 230. The storage unit 120 is a means for storing the information read by the reading unit 110. The scheduled time receiving unit 130 is a means for receiving input of time information indicating the scheduled collection time of the track closure indicator light 200. The registration unit 140 is a means for storing in the storage unit 120 the identification information related to the track closure indicator light 200 read by the reading unit 110 and the time information related to the track closure indicator light received by the scheduled time receiving unit 130 in association with each other. The alert setting unit 150 is a means for setting an alert time, which is a predetermined time that is set before or after the scheduled collection time and is set for each track closure indicator light 200. The collection processing unit 160 is a means for determining whether the identification information read by the reading unit 110 is stored in the storage unit 120, and for determining that the track closure indicator light 200 related to the identification information has been collected if it is stored. The notification unit 170 is a means for outputting a notification that a track closure indicator light 200 that has not been determined to have been collected by the collection processing unit 160 has not been collected when the alert time for that track closure indicator light 200 arrives.

The inventors have come to the conclusion that, in the previous technology, for example, in Patent Document 1, a two-dimensional code is attached to a tool, the two-dimensional code is photographed before work begins, the tool identification information indicated by the two-dimensional code is recognized, and after work is completed, the two-dimensional code is photographed again to recognize the tool identification information indicated by the two-dimensional code, and the tool identification information recognized before work begins is compared with the tool identification information recognized after work is completed. If there is a discrepancy in the number of tools, the information of the tool that has been left behind is displayed so that it is visually clear. Therefore, the information of the tool that has been left behind can only be identified after the work is completed, and the safety of train operation after track construction cannot be ensured. In other words, according to the invention of Patent Document 1, although it is possible to identify a tool that has been left behind, this is only after the construction is completed, and there is a possibility that a train will operate after track construction before the tool that has been left behind can be identified, and it is not possible to prevent a major accident.
Therefore, in this system, a track closure indicator light 200, a reading unit 110, a memory unit 120, a scheduled time receiving unit 130, a registration unit 140, an alert setting unit 150, a collection processing unit 160, and an alarm unit 170 are provided, and a determination is made as to whether or not the identification information read by the reading unit 110 is stored in the memory unit 120, and if it is stored, the collection processing unit 160 determines that the track closure indicator light 200 related to the identification information has been collected, and when the alert time arrives for a track closure indicator light 200 that has not been determined to have been collected by the collection processing unit 160, the alarm unit 170 outputs an alarm that the track closure indicator light 200 has not been collected.

The system is explained in more detail below.

Construction work carried out with railway tracks closed refers to work carried out when vehicles are not allowed to run on the railway tracks, for example, after railway operations have ended or when railway services are suspended. Therefore, it is necessary to inform people that the railway tracks are closed. In particular, when work is carried out after railway operations have ended, it is at night, so it is efficient to inform people that the railway tracks are closed using indicator lights with light-emitting elements. Therefore, when construction work is carried out with railway tracks closed, a method is adopted in which a track closed indicator light 200 shown in Figure 2 is used to inform people that the railway tracks are closed. Here, the track closed indicator light 200 will be explained using Figure 2.

As shown in Fig. 2(a), the track closed indicator light 200 is composed of a light emitting unit 220 and a stand 210 that supports the light emitting unit 220. Although not shown, the track closed indicator light 200 is equipped with a battery that causes the light emitting unit 220 to emit light. In addition to the battery built into the track closed indicator light 200, a battery may be provided separately from the track closed indicator light 200.
As shown in Fig. 2(b), a readable information recording unit 230 is provided on the back of the light-emitting unit 220. The location of the readable information recording unit 230 is not limited to the location shown in Fig. 2(b) as long as it is provided on the track closed indicator light 200. It is preferable that the information recording unit 230 is provided in a location that does not affect the ease of reading by the reading unit 110 or the function of the track closed indicator light 200 (the function of informing the user that the track is closed), and is therefore preferably affixed to the stand 210 or the light-emitting unit 220. In this embodiment, the information recording unit 230 is provided by being affixed to the track closed indicator light 200, but it may also be placed in a predetermined transparent case and hung from the track closed indicator light 200, for example.

The identification information for identifying an individual is information for identifying the track closed indicator light 200, and specifically, is information that identifies an individual by information including numbers such as Line Closed 1, Line Closed 2, ..., or information including the location where the track closed indicator light 200 is used, such as Line A Up and Line A Down, which are the locations where the track is closed. In addition, the identification information may be simple numbers (1, 2, ...). The content of the identification information may be determined taking into consideration the amount of information that can be stored in the information recording unit 230 and whether it is easy for workers to identify. In this embodiment, Line Closed 1, Line Closed 2, ... are stored.
The readable information recording unit 230 is one that can extract recorded information by reading it with a specific reading device, specifically, an IC tag, a barcode, a two-dimensional barcode, etc. Any of these may be used, but in this embodiment, in consideration of the amount of information that can be recorded and the ease of creating the information recording unit 230, the information recording unit 230 is configured as a two-dimensional barcode.

The information processing terminal 100 is a computer capable of executing various processes, and specifically, as described below, is a portable terminal that can be carried around. The information processing terminal 100 includes an input device such as a touch device or a pointing device, a central processing unit (CPU), and a storage device such as a memory.
The reading unit 110 is a device that extracts information recorded in the information recording unit 230, and is one of the input devices. The reading unit 110 is of different types, such as those that read using light and those that read using radio waves, depending on the type of the information recording unit 230. In this embodiment, since the information recording unit 230 is configured as a two-dimensional barcode, the reading unit 110 is configured as a two-dimensional barcode reader. The reading unit 110 in this embodiment corresponds to a function of reading a two-dimensional barcode using a camera provided in the information processing terminal 100, but a device that only has a function of reading the information recording unit 230 may be provided separately from the information processing terminal 100, and the read result may be input to the information processing terminal 100. In this embodiment, in order to simplify the configuration of the track closure indicator light management system 10 with the misplacement prevention function, the information processing terminal 100 is configured to include the reading unit 110.
The storage unit 120 that stores the information read by the reading unit 110 is a storage device provided in the information processing terminal 100, and specifically corresponds to a RAM (Random Access Memory) provided in the information processing terminal 100. However, the storage unit is not limited to a storage device provided in the information processing terminal 100, and may be, for example, a storage device provided on a network that can be accessed via the network. In this embodiment, in order to simplify the configuration of the track closure indicator light management system 10 with a function to prevent misplacement, the information processing terminal 100 is configured to include the storage unit 120.

The scheduled recovery time of the track closure indicator light used in construction work is a time determined in advance based on the time when construction work will be completed with the track closed. The scheduled recovery time may be the time when construction work will be completed with the track closed, or may be a predetermined time before the track closure is completed and railway operations begin. It may also be in Japan Standard Time, such as XX:XX minutes, or a period of time, such as XX hours from the start of construction. In this embodiment, taking into consideration the ease of work, the scheduled recovery time is Japan Standard Time, which is determined in advance based on the time when construction work will be completed with the track closed.
The scheduled time receiving unit 130 is a means for inputting the scheduled collection time described above, and specifically, receives input using an input device such as a touch device provided on the information processing terminal 100. The scheduled collection time input by the scheduled time receiving unit 130 is stored in the storage unit 120.
The registration unit 140 is a means for correlating the identification information relating to the track closure indicator light 200 read by the reading unit 110 with the time information relating to the track closure indicator light 200 received by the scheduled time receiving unit 130 and storing them in the memory unit 120, and corresponds to an arithmetic processing device provided in the information processing terminal 100.

The notification unit 170 includes a clock means and can obtain information on the current time. The clock means can use a clock function of the mobile terminal.
The alert time is a time that is set before or after the scheduled collection time and is set for each track closure indicator light 200. The alert time may be the scheduled collection time itself (exact time) input by the scheduled time receiving unit 130, or may be a time a predetermined period before the scheduled collection time (for example, 30 minutes before). Alternatively, the alert time may be set after the scheduled collection time (for example, 10 minutes after), assuming that it is before the time when the train starts operation. The set alert time may be, for example, the scheduled collection time itself, or multiple times including the scheduled collection time and a time a predetermined period before the scheduled collection time. The set alert times may be the same number for all track closure indicator lights 200 and may be times the same period before the scheduled collection time, or may be different numbers for each track closure indicator light 200 and times different periods before the scheduled collection time. It is preferable to set the alert time taking into consideration the construction work content and operation method performed by closing the track. The alert setting unit 150 corresponds to a processing device provided in the information processing terminal 100 .
When the alert time to be set is a time a predetermined period (predetermined period A) before the scheduled collection time or a time a predetermined time (predetermined period B) after the scheduled collection time, it is set as follows. Predetermined period A and predetermined period B are stored in advance in the storage unit 120. When the scheduled collection time is input, the alert setting unit 150 subtracts or adds the stored predetermined period A or predetermined period B from the scheduled collection time and sets it as the alert time. Note that, although the predetermined period A and predetermined period B are stored in advance in this embodiment, they may be changeable by the worker. By allowing the worker to change them, it is possible to set an alert time suitable for the construction work content and operation method performed with the track closed.

The collection processing unit 160 is a means executed by an arithmetic processing device provided in the information processing terminal 100. The collection processing unit 160 is a means for determining whether or not the identification information read by the reading unit 110 is stored in the memory unit 120, and, if stored, determining that the track closure indicator light 200 related to the identification information has been collected.
The notification unit 170 compares the current time acquired from the clocking means with the above-mentioned alert time, and when the alert time for the track closure indicator light 200 that has not been determined to have been collected by the collection processing unit 160 arrives, outputs a notification that the track closure indicator light 200 has not been collected. Specifically, the notification unit 170 notifies the worker by display or sound using the display device 180 and the speaker 185 provided in the information processing terminal 100. In this way, the notification unit 170 can make the worker aware that the track closure indicator light 200 has been left behind by outputting the notification using the display device 180 and the speaker 185 provided in the information processing terminal 100. In this embodiment, the notification unit 170 is the display device 180 and the speaker 185 provided in the information processing terminal 100, but is not limited to this. For example, a display light (not shown), a display device (not shown), and a speaker (not shown) may be provided in a position that is easy for multiple workers to understand, and a predetermined control signal may be sent from the arithmetic processing device of the information processing terminal 100 to the display light, the display device, and the speaker to output an alert. In this way, for example, by providing a display device on the wall of a construction management office, or providing a display light and a speaker next to the track closure indicator light 200, it is possible for multiple workers to easily understand that the alert time has arrived at the same time.

<Operation method of the track closure indicator light management system 10 with a function to prevent misplacing>
Next, a method of operating the track-block indicator light management system 10 with a function to prevent misplacement will be described with reference to FIGS.
In this embodiment, a case will be described in which construction work is performed by closing four tracks, the A line up, A line down, B line up, and B line down. Of the four tracks to be closed, a track closed indicator light 200 with identification information "line closed 1" is placed on the A line up, a track closed indicator light 200 with identification information "line closed 2" is placed on the A line down, a track closed indicator light 200 with identification information "line closed 3" is placed on the B line up, and a track closed indicator light 200 with identification information "line closed 4" is placed on the B line down.
A construction management office is provided next to the tracks where construction work is carried out. An information processing terminal 100 is provided in the construction management office, and operations using the information processing terminal 100 are carried out in the construction management office, such as reading the information recording unit 230 attached to the track closure indicator light 200 with the reading unit 110, receiving input of time information indicating the scheduled collection time with the scheduled time receiving unit 130, and reading the information recording unit 230 attached to the track closure indicator light 200 with the reading unit 110 when the track closure indicator light 200 is brought into the construction management office.

Before the track is closed and construction work is started, the track closed indicator light 200 is stored in the construction management office. When construction work is started, the worker takes the track closed indicator light 200 out of the construction management office and reads the information recording unit 230 provided in the track closed indicator light 200 with the reading unit 110. When the information recording unit 230 provided in the track closed indicator light 200 is read by the reading unit 110, it is preferable that the worker performs a confirmation operation while using the display device 180 provided in the information processing terminal 100 (mobile terminal).
A computer program (hereinafter, this program) for making the information processing terminal (mobile terminal) 100 execute the reading process, the storage process, the scheduled time reception process, the registration process, the alert setting process, the collection process, and the notification process is installed in the information processing terminal (mobile terminal) 100. The reading process is a process of reading the identification information recorded in the readable information recording unit 230. The storage process is a process of storing the information read by the reading process. The scheduled time reception process is a process of receiving the input of time information indicating the scheduled collection time of the track closure indicator light 200. The registration process is a process of storing the identification information related to the track closure indicator light 200 read by the reading process and the time information related to the track closure indicator light 200 received by the scheduled time reception process in association with each other. The alert setting process is a process of setting an alert time that is a predetermined time that is determined before or after the scheduled collection time and is determined for each track closure indicator light 200. The collection process is a process for determining whether or not the identification information read by the reading process is stored, and if it is stored, determining that the track closure indicator light 200 related to the identification information has been collected. The notification process is a process for outputting a notification that the track closure indicator light 200 has not been collected when the alert time for the track closure indicator light 200 that has not been determined to be collected by the collection process arrives.

When this program is started, a menu screen is displayed on the display device 180, and multiple display contents including "Register" and "Collect" are displayed. One of the multiple display contents selected from the menu screen is (1) in Fig. 4(a). When the information recording unit 230 of the track closure indicator light 200 is read by the reading unit 110, the user selects "Register" from the menu screen to display the display content (1) in Fig. 4(a).
When the information recording unit 230 of the track closed indicator light 200 is read by the reading unit 110, the display content shown in (1) of FIG. 4(a) is displayed on the display device 180. When the worker inputs "Register" on the screen shown in (1) of FIG. 4(a) to start reading the information recording unit 230 of the track closed indicator light 200 to be taken out of the construction management office, the display content shown in (2) of FIG. 4(a) is displayed. Then, the worker reads the information recording unit 230 of the track closed indicator light 200 to be taken out by the reading unit 110, and the display content shown in (3) of FIG. 4(a) is displayed. Since the track closed indicator light 200 whose information recording unit 230 has been read this time has "Line Closed 1" recorded as the identification information, "Line Closed 1" is displayed as shown in (3) of FIG. 4(a), and a screen for inputting time information indicating the scheduled collection time is displayed. The worker then inputs "4:00" as the scheduled collection time of the track closed indicator light 200 in which "line closed 1" is recorded, and inputs "register". This means that the track closed indicator light 200 in which "line closed 1" is recorded is to be taken out, and "4:00" is registered as the scheduled collection time of the track closed indicator light 200. The display device 180 displays the display content shown in FIG. 5(a), and the worker can confirm that the track closed indicator light 200 in which "line closed 1" is recorded has been taken out and become a subject of management, that "4:00" has been registered as the scheduled collection time of the track closed indicator light 200, and that the track closed indicator light 200 has been taken out (not collected). The worker then takes the track closed indicator light 200 out of the construction management office and uses it at the track construction site on the uphill line of Line A.

Next, when the work is completed and the worker brings the track closure indicator light 200 to the work management office, the information recording unit 230 provided on the track closure indicator light 200 that the worker brings to the work management office is read by the reading unit 110.
When the information recording unit 230 of the track closed indicator light 200 is to be brought to the construction management office, the program is started and "collection" is selected from the menu screen, and the display content shown in Fig. 4(b) (1) is displayed on the display device 180. In order to start reading out the information recording unit 230 of the track closed indicator light 200 to be brought to the construction management office, the worker inputs "collection" on the screen shown in Fig. 4(b) (1), and the display content shown in Fig. 4(b) (2) is displayed. Then, the worker reads the information recording unit 230 of the track closed indicator light 200 to be brought in by the reading unit 110, and the display content shown in Fig. 4(b) (3) is displayed. This time, the track closed indicator light 200 whose information recording unit 230 has been read has "Line Closed 1" recorded as its identification information, so "Line Closed 1" is displayed as shown in (3) of FIG. 4(b), and if there is no mistake, when "Collect" is entered, it is registered that the track closed indicator light 200 has been brought (recovered) to the construction management office. At this time, as shown in FIG. 5(b), "Line Closed 1" and the scheduled collection time "4:00" displayed on the display device 180 due to the scheduled collection time of the track closed indicator light 200 being registered are erased, and the worker can understand that the track closed indicator light 200 equipped with the information recording unit 230 in which "Line Closed 1" is recorded has been brought (returned) to the construction management office. Note that "Line Closed 1" and the scheduled collection time "4:00" in FIG. 5(b) are written in dashed lines to represent the appearance of being erased, and are not actually displayed in dashed lines.

The above-described operation is carried out when a worker takes the track closure indicator light 200 out of the construction management office, and when a worker brings the track closure indicator light 200 into the construction management office before the set scheduled collection time (before the set alarm time).
The following operation is performed when the worker is unable to bring the track closure indicator light 200 to the construction management office even at the scheduled collection time (set alarm time) set by the worker.
The alert time is set by the alert setting unit 150 based on the scheduled collection time set by the worker when taking the track closure indicator light 200 out of the construction management office. This setting may be set by the worker using an input device for each track closure indicator light 200, as with the scheduled collection time, but in this embodiment, a predetermined period before the scheduled collection time is automatically set, and the first notification is set to be made 5 minutes before the scheduled collection time, and the second notification is set to be made at the scheduled collection time. Therefore, when the worker sets the scheduled collection time, the alert time is also set.
FIG. 5A shows the display contents showing a list of track closure indicator lights 200 taken out from the construction management office, which are displayed on the display screen of the display device 180 of the information processing terminal 100.
In Fig. 5(a), it is shown that there are four track closed indicator lights 200 taken out from the construction management office: "Line Closed 1", "Line Closed 2", "Line Closed 3", and "Line Closed 4". In addition, "Line Closed 1" has the scheduled recovery time set to "4:00", and similarly, "Line Closed 2" has the scheduled recovery time set to "3:00", "Line Closed 3" has the scheduled recovery time set to "2:00", and "Line Closed 4" has the scheduled recovery time set to "0:00". The current time (12:57) is displayed in the upper right corner of Fig. 5(a).
Here, when comparing the scheduled collection time set in the track closure indicator light 200 with the current time, "Closed Line 1" is displayed in black because the current time has not passed the scheduled collection time. In a similar comparison, "Closed Line 2" is displayed in black because the current time has not passed the scheduled collection time. In a similar comparison, "Closed Line 3" is displayed in red with "Not yet" (displayed in bold in Figs. 5(a) and (b)), as the current time has passed the scheduled collection time and the alert time, to notify that the scheduled collection time and the alert time have passed. In a similar comparison, "Closed Line 4" is displayed in red with "Not yet" (displayed in bold in Figs. 5(a) and (b)), as the current time has not passed the scheduled collection time but has passed the alert time, to notify that the alert time has passed. In addition, since “Line Closed 3” is a message that has passed not only the alert time but also the scheduled collection time, in addition to the notification on the display device 180, the notification may be by voice from the speaker 185 or by vibration using the vibration function provided in the information processing terminal 100.
In this way, if it is determined that the track closure indicator light 200 has not been brought to (recovered) at the construction management office even after the alert time and the scheduled collection time have passed, the worker can use the information processing terminal 100 to identify the track closure indicator lights 200 that have not been brought in, so that the track closure indicator lights 200 can be reliably collected before the train starts operating, thereby ensuring the safety of operations.
It should be noted that the above-mentioned display content displayed on the display device 180 of the information processing terminal 100, the number of track closure indicator lights 200 to be read, and the various information to be set are merely examples, and it goes without saying that the content will depend on the track construction situation.

<Processing flow of the track closure indicator light management system 10 with a function to prevent misplacing>
Next, the process flow of the track-closure indicator light management system 10 with a function to prevent misplacement will be described with reference to FIG.
Fig. 6 is a process flow chart of the track-closed indicator light management system with a function to prevent misplacing 10. Note that Fig. 6 only shows the core process of the track-closed indicator light management system with a function to prevent misplacing 10. Therefore, in addition to the process shown in Fig. 6, for example, as explained in the operation method of the track-closed indicator light management system with a function to prevent misplacing 10, a process of display control of the display device 180 provided in the information processing terminal 100 is also performed.

Step S111 is a process for determining whether or not the reading unit 110 has read the information recording unit 230. If the reading unit 110 has read the information recording unit 230, the process proceeds to step S112; if not, the process proceeds to step S118.

Step S112 is a process for determining whether or not the identification information read in step S111 is stored in the memory unit 120. If the identification information read in step S111 is not stored in the memory unit 120, proceed to step S113; if it is stored, proceed to step S117. If the identification information read in step S111 is not stored in the memory unit 120, the information recording unit 230 is read by the reading unit 110 when the worker takes the track closure indicator light 200 out of the construction management office; if it is stored, the information recording unit 230 is read by the reading unit 110 when the worker takes the track closure indicator light 200 to the construction management office.

Step S113 is a process of storing the identification information read in step S111 in the memory unit 120.

Step S114 is a process for inputting the scheduled collection time of the track closure indicator light 200 having the information recording unit 230 in which the identification information read in step S111 is recorded. This process is also a process for accepting the input of time information input by the worker using the input device. It is possible to input (set) the scheduled collection time for each track closure indicator light 200.

Step S115 is a process of registering the identification information read in step S111 and the time information input in step S114 in correspondence with each other in the memory unit 120.

Step S116 is a process of setting a time before the time information (scheduled collection time) registered in step S115 as the alert time. The alert time may be the same as the time information (scheduled collection time) registered in step S115, may be set to a predetermined period before the time information (scheduled collection time), or may be set to multiple times.

Step S117 is a process performed in step S112 when the identification information read in step S111 is stored in the memory unit 120, and the track closure indicator light 200 equipped with the information recording unit 230 in which the identification information is recorded is regarded as having been collected, and information indicating that it has been collected is stored in the memory unit 120.

Step S118 is a process for determining whether or not the alert time is one of the alert times set for each track closure indicator light 200. If it is not determined that the alert time is the time, this process ends. On the other hand, if it is determined that the alert time is the time, the process proceeds to step S119.

Step S119 is a process for determining whether or not the track closure indicator light 200 at the alert time has been collected when it is determined in step S118 that it is the alert time. If the track closure indicator light 200 at the alert time has been collected, this process ends. On the other hand, if it is determined that it has not been collected, the process proceeds to step S120. Note that whether or not the target track closure indicator light 200 has been collected is determined based on the information that it has been collected that is stored in the memory unit 120 in step S117.

In step S120, if it is determined in step S119 that the target track closure indicator light 200 has not been collected, the notification unit 170 outputs a notification that the light has not been collected.

In this way, by processing the track closure indicator light management system 10 with a function to prevent leaving behind, it is possible to manage the track closure indicator lights 200 that have been taken from the construction management office to the construction site and the track closure indicator lights 200 that have been brought from the construction site to the construction management office, so that it is possible to identify track closure indicator lights 200 that have not been returned (collected) to the construction management office even when the scheduled collection time has arrived, and if there are any track closure indicator lights 200 that have not been collected at the scheduled collection time, it is possible to notify that fact.

<Modification of track closure indicator light>
A modified example of a track closure indicator light 300 will be described below.
The track closure indicator light 300 of this modification differs from the information recording unit 230 described in the above embodiment in the configuration of the information recording unit 330. In other words, other than the configuration of the information recording unit 330, the track closure indicator light 300 is the same as the track closure indicator light 200.
As shown in Figures 2(a) and 2(b), the track closure indicator light 300 comprises a stand 210 and a light-emitting unit 220 provided on the upper part thereof and used for illumination during construction work.

The information recording section 330 of this modified example will be described with reference to FIG.
As shown in FIG. 7A , the information recording section 330 is composed of a substrate 331 , an adhesive layer 332 , a release paper 333 , a white paint layer 334 , a phosphorescent layer 335 , a transparent film 336 and a two-dimensional barcode 337 .
The substrate 331 is a sheet-like substrate, and is made of paper, a plastic film, or the like.
The adhesive layer 332 is applied to the back surface of the base material 331 and can be attached to the back surface of the light-emitting portion 320 of the track block indicator light 300.
The release paper 333 is attached under the adhesive layer 332 (on the side opposite to the substrate 331 ).
The white paint layer 334 is provided on the front surface side (the side opposite to the adhesive layer 332) of the base material 331, and a white paint is applied to the front surface side of the base material 331. Note that since the white paint layer 334 is provided to make the light emitted from the phosphorescent agent layer 335 stand out, it does not have to be provided when the base material 331 is white or when the light emitted from the phosphorescent agent layer 335 is strong.
The luminous agent layer 335 is a layer formed by applying a luminous agent onto the white paint layer 334. Here, the luminous agent is a substance that absorbs light energy and emits visible light when exposed to light including ultraviolet rays, and is a phosphorescent substance such as strontium sulfide, zinc sulfide, or cadmium sulfide.
The transparent film 336 is provided on the upper surface of the luminous agent layer 335 to protect the luminous agent layer 335 and to print a two-dimensional barcode 337 thereon.

<Modification of the Track Closure Indicator Light Management System>
The track closure indicator light management system 11 of this modified example will be described with reference to FIG.
As shown in FIG. 8, the track closure indicator management system 11 with a function to prevent misplacement of the present embodiment (hereinafter, sometimes referred to as the present system) includes at least a track closure indicator 300 to which an information recording unit 330 is attached, and an information processing terminal 100 having a reading unit 110 that reads identification information for identifying the individual track closure indicator 300 from the information recording unit 330. In addition to the reading unit 110, the information processing terminal 100 includes a memory unit 120, a scheduled time reception unit 130, a registration unit 140, an alert setting unit 150, a collection processing unit 160, and an alarm unit 170. In addition to the above, the information processing terminal 100 preferably includes a display device 180 and a speaker 185. In addition to the information processing terminal 100, a computer 400 and a barcode printer 410 are provided. The computer 400 and the barcode printer 410 do not need to be connected to the information processing terminal 100 via a network. It goes without saying that the computer 400 and the barcode printer 410 may be network-connected to the information processing terminal 100. The track closure indicator light management system 11 is similar to the track closure indicator light management system 10, except for the configuration of the information recording unit 330 and the inclusion of the computer 400 and the barcode printer 410.
The computer 400 controls the barcode printer 410 to print a two-dimensional barcode on which identification information is recorded on the sheet shown in Fig. 7(a). Specifically, the computer 400 transmits information on the two-dimensional barcode to be printed on the sheet shown in Fig. 7(a) to the barcode printer 410, and the barcode printer 410 prints the two-dimensional barcode on the sheet based on the received information. In this embodiment, the computer 400 is provided separately from the information processing terminal 100 to control the barcode printer 410, but the information processing terminal 100 may transmit information on the two-dimensional barcode to be printed to the barcode printer 410 and control the barcode printer 410. In this embodiment, the computer 400 is provided separately from the information processing terminal 100 because operation errors can be prevented by using the information processing terminal 100 exclusively for managing the removal/recovery of the track closure indicator light 300.

FIG. 7B shows an image of the printed information recording section 330.
The information recording unit 330 shown in FIG. 7( b ) is attached to the back surface of the light emitting unit 320 of the track closure indicator light 300 .
Since construction work that involves closing railway tracks is often carried out at night, there is a risk that workers may have difficulty identifying the location of the information recording unit 330. By using the track closure indicator light 300 configured in this manner, workers can easily identify the location of the information recording unit 330 even in the dark, making it possible to carry out work efficiently.
In this embodiment, the two-dimensional barcode 337 is printed on the base material 331 having the luminous agent layer 335 applied thereto and the transparent film 336 provided on the upper surface of the luminous agent layer 335, but the two-dimensional barcode 337 may be printed on a predetermined sheet (not shown) and the printed predetermined sheet may be affixed to the base material 331 having the luminous agent layer 335 applied thereto and the transparent film 336 provided on the upper surface of the luminous agent layer 335. When the information recording unit 330 thus created is provided on the track closure indicator light 300, the worker can easily find the position of the information recording unit 330 even in the dark, and therefore the work can be performed efficiently.

The present invention is not limited to the above-described embodiment, and various modifications and improvements are possible.

In the above-described embodiment and its modified examples, the information recording units 230, 330 recorded identification information that identifies the individual track closure indicator lights 200, 300, but in addition to this, usage location information, which is information about the location where the track closure indicator lights 200, 300 are used during construction work, may also be recorded.
Specifically, as shown in FIG. 3, the track-closed indicator light 200 having the information recording unit 230 in which the identification information of "Line Closed 1" is recorded is used for the A-line up, and the track-closed indicator light 200 having the information recording unit 230 in which the identification information of "Line Closed 2" is recorded is used for the A-line down. Therefore, the information of "Line Closed 1" is recorded in the information recording unit 230 in accordance with the identification information of "Line Closed 1", and the information recording unit 230 is provided in the track-closed indicator light 200. When the information recording unit 230 is read by the reading unit 110, the information of "Line Closed 1" as well as "Line Up" can be read, and these pieces of information are stored in the storage unit 120. In addition, the information of the location where the track-closed indicator light 200 is to be provided may be information such as "XX kilometer point" instead of the track name such as "Line Up". By configuring in this way, it is easier for the worker to grasp the location where the track-closed indicator light 200 read by the reading unit 110 is to be placed. In addition, as shown in Figure 5, it becomes easier for workers to identify the locations of uncollected track closure indicator lights 200 among the track closure indicator lights 200 taken out of the construction management office, thereby improving work efficiency.

A method of recording use location information in the information recording unit 330 using the track close indicator light management system 11 according to the modified example shown in Fig. 8 will be described. Note that in the track close indicator light management system 11 according to the modified example shown in Fig. 8, the two-dimensional barcode is printed by the barcode printer 410 on a sheet provided with a phosphorescent agent, but the two-dimensional barcode may be printed on a sheet not provided with a phosphorescent agent. That is, the same can be done when recording use location information in the information recording unit 230.
As shown in FIG. 8, the computer 400 and the barcode printer 410 do not need to be connected to the information processing terminal 100 via a network.
Since the location where the track closure indicator light 300 is placed is determined by the construction site, it is possible for the worker to input the use location information, which improves work efficiency. In this embodiment, a use location reception means for the worker to input the use location information is provided in the computer 400. The worker inputs the use location information using an input device (not shown) such as a keyboard or a touch pen provided in the computer 400. Then, based on the information received by the use location reception means, a two-dimensional barcode recording the information "Line Closed 1" and "A Line Up" is printed using the barcode printer 410. In this manner, information suitable for the construction site can be recorded in the information recording unit 330. In this embodiment, both "Line Closed 1", which is the identification information for identifying the individual track closure indicator light 300, and "A Line Up", which is the use location information, are recorded in the information recording unit 330, but only "A Line Up", which is the use location information, may be recorded. In this case, "A Line Up" is both the identification information for identifying the individual track closure indicator light 300 and the use location information. In this way, the worker can set what information is to be recorded in the information recording unit 330 within the range of the amount of information that can be recorded in the information recording unit 330, thereby making it possible to improve work efficiency.

In the above-described embodiment, the alert setting unit 150 sets one alert time, and the notification unit 170 outputs a notification when the alert time is reached. However, since misplacing the track closure indicator light 200 is highly likely to lead to a serious accident, it is preferable to set multiple alert times and output multiple notifications.
For example, in the case of the track closed indicator light 200 having the information recording unit 230 in which the identification information of "line closed 1" is recorded, the first notification may be made at 3:55, which is five minutes before the scheduled collection time of 4:00, and the second notification may be made at the scheduled collection time of 4:00. The first notification and the second notification may be made in the same notification mode, but it is preferable that the second notification be made easier for the worker to grasp than the first notification, such as by making the notification sound output from the speaker 185 louder than the first notification, by using a darker color for the notification output on the display device 180, by using both the display device 180 and the speaker 185 for the second notification while only outputting the first notification on the display device 180, or by adding a notification output by vibration. By making the first and second notifications different notification modes in this way, it becomes easier for the worker to understand which notification it is, and by making the second notification, which is closer to the scheduled collection time, more easily understandable than the first notification, it is possible to notify the worker that the scheduled collection time is approaching (that the scheduled collection time has arrived). Therefore, it is possible to reliably and easily collect the uncollected track closure indicator lights 200 at the scheduled collection time, and it is possible to prevent any disruption to railway operations after construction.

The information processing terminal 100 is equipped with a display device 180 (display means). When the identification information of the track-closed indicator light 200 and the time information of the track-closed indicator light 200 accepted by the scheduled time accepting unit 130 are recorded in the memory unit 120 by the registration unit 140 in association with each other, the display device 180 displays the identification information (corresponding to "track-closed 1" in FIG. 5(a)) and the time information (corresponding to "4:00" in FIG. 5(a)) in one line, as shown in FIG. 5(a). This allows the worker to visually understand that the track-closed indicator light 200 has been read by the reading unit 110 and that the scheduled collection time has been accepted by the scheduled time accepting unit 130. When the recovery processing unit 160 determines that the track closed indicator light 200 has been recovered, the identification information (corresponding to "Line Closed 1" in FIG. 5(b)) and the time information (corresponding to "4:00" in FIG. 5(b)) that were displayed in one line disappear from the display content, as shown in FIG. 5(b). This allows the worker to visually understand that the track closed indicator light 200 with the identification information "Line Closed 1" recorded in the information recording unit 230 has been recovered.
In the above, the display device 180 provided in the information processing terminal 100 is exemplified as the display means, but a display means may be provided separately from the information processing terminal 100. For example, a large monitor may be provided in a construction management office as the display means. By configuring in this way, it becomes easier for multiple workers to grasp the take-out/recovery status of the track closure indicator light 200.

As described above, the information processing terminal 100 in the construction management office is provided with the reading unit 110, memory unit 120, scheduled time receiving unit 130, registration unit 140, alert setting unit 150, collection processing unit 160 and notification unit 170. In addition, it is preferable that the information processing terminal 100 is a portable mobile terminal such as a mobile phone or tablet terminal. By using a mobile phone or tablet terminal, which is often used in daily life, as the information processing terminal 100, even workers who do not have a deep knowledge of the information processing terminal 100 can easily learn how to operate it.

In the above-described embodiment, the information processing terminal 100 is provided in the construction management office, and the reading unit 110 reads the information recording unit 230 provided in the track closure indicator light 200 in the construction management office. However, if a portable information processing terminal 100 is used, the worker may take the information processing terminal 100 out of the construction management office and read the information recording unit 230 provided in the track closure indicator light 200 in the place where the track closure indicator light 200 is placed by the reading unit 110. For example, at a construction site where the track closure indicator light 200 is placed, the identification information may be read by the reading unit 110 at the start of construction and a registration process may be performed, and the identification information may be read by the reading unit 110 at the end of construction and a recovery process may be performed. Then, while checking the display content (particularly, see FIG. 5) displayed on the information processing terminal 100, it may be confirmed that there is no error in the placement position of the track closure indicator light 200. By implementing this type of operation, it is possible to prevent the worker from placing the track closure indicator light 200 in the wrong position, or from bringing the wrong track closure indicator light 200 to the construction management office. Note that, for construction work carried out on the same day (at the same time), processing using the information processing terminal 100 may be carried out at both the construction management office and the construction site, or only at one of them, depending on the situation at the construction site.

In the above-described embodiment, the track closure indicator light 200 is described assuming its use in track closure work carried out at night. However, the above-described track closure indicator light 200 may also be used in work carried out during the day. Even in the case of work carried out during the day, the track closure indicator light 200 is preferably used, particularly on days with poor visibility such as cloudy days or thick fog. It goes without saying that this makes it possible to reliably retrieve indicator lights from a work site even in cases where it is difficult to visually find a light that has been left behind due to poor visibility such as cloudy days or thick fog.

The present invention described above is not limited to the above description, but includes various modifications, improvements, and other aspects as long as the object of the present invention is achieved.
