The main key of the structure table 134 may be a road name 1341, a top and bottom 1342, and a position ID 1343. The structure table 134 may be updated by updating each item of the existing record, deleting the existing record, and adding a new record. Only the latest record identified by the primary key of the structure table 134 may be retained.

FIG. 6 shows an example of the deterioration prediction table 135. The result of predicting the future deterioration state of the road from the deterioration state index of the deterioration state table 131 is stored.

The deterioration prediction table 135 has, as data items, a road name 1351 which is a name of a road, upper and lower parts 1352 indicating up or down, a lane 1353, a position ID 1354, and a deterioration state index 1355 (1355-1 to 135-4). And a forecast date 1356.

The deterioration state index 1355 is an index indicating a future deterioration state predicted by the deterioration prediction unit 107. The deterioration state index 1355 may have a plurality of generation indices. That is, the deterioration state index 1355 may have an index that predicts the deterioration states of a plurality of periods ahead at regular time intervals. In the example of the same figure, it has information of four generations from deterioration state index (predicted generation 1) 1355-1 to deterioration state index (predicted generation 4) 1355-4.

It may be stored in the prediction table 135.

Returning to FIG. 1, the communication unit 101 transmits/receives data to/from the terminal device 3. For example, when the communication unit 101 transmits the display screen data generated by the display control unit 111 to the terminal device 3, a display screen according to the display screen data is displayed on the display device 302. The communication unit 101 also acquires the data transmitted from the terminal device 3 and transmits the data to the control unit 103. For example, the communication unit 101 receives data or an instruction according to the input accepted by the input device 301 when any one of the screens described below is displayed on the display device 302, and transmits the data or the instruction to the control unit 103.

FIG. 7 shows a processing procedure of the communication unit 101.

The communication unit 101 may be activated by receiving the data transmitted from the communication device 303 or the display control unit 111. The communication unit 101 first determines the source of data (S101).

When the data transmission source is the communication device 303, the communication unit 101 receives the data transmitted from the communication device 303 (S103). The communication unit 101 transmits the received data to the control unit 103 and activates the control unit 103 (S105).

When the data transmission source is the display control unit 111, the communication unit 101 receives the display screen data from the display control unit 111 (S107). The display screen data may be, for example, data for screen display in which information to be displayed in a predetermined screen template is set. The displayed screen may be, for example, each screen shown in FIG. 16 and subsequent figures. The communication unit 101 transmits the received display screen data to the communication device 303 (S109).

Next, the control unit 103 performs preprocessing for referring to or updating the table of the storage unit 130 according to the received data.

FIG. 8 shows a processing procedure of the control unit 103.

When activated by the communication unit 101, the control unit 103 receives the data transmitted from the communication unit 101 (S201). The received data may be the data transmitted from the communication device 303.

The control unit 103 determines the type of the received data (S203).

When the received data is a reference request, the control unit 103 transmits the received data to the extraction unit 109 and activates the extraction unit 109 (S231). At this time, the reference request may include identification information of a display layout for displaying the data related to the reference request.

When the received data is an update request, the control unit 103 determines the type of table to be updated (S205). The control unit 103 sets a flag according to the type of table to be updated in the update data. That is, when the update data is update data of the deterioration state table 131, a flag indicating the deterioration state table is set in the update data (S207). When the update data is update data of the equipment state table 132, a flag indicating the equipment state table is set in the update data (S209). When the update data is the update data of the road table 133, a flag indicating the road table is set in the update data (S211). When the update data is the update data of the structure table 134, a flag indicating the structure table is set in the update data (S213).

The control unit 103 transmits the update data to which the flag has been added to the storage control unit 105 and activates the storage control unit 105 (S215).

Next, the storage control unit 105 inputs/outputs and updates the data of the table stored in the storage unit 130.

FIG. 9 shows a processing procedure of the storage control unit 105.

When the storage control unit 105 is activated, the activation source determination is performed. In the first activation source determination, the storage control unit 105 determines whether the processing is activated by batch processing or not (S301).

In the case of starting by batch processing, the storage control unit 105 performs error correction processing (S330). Details of the error correction process will be described later.

If the startup is not performed by batch processing, the storage control unit 105 further determines the startup source (S303).

Here, when the activation source is the deterioration prediction unit 107, the storage control unit 105 receives the deterioration prediction data from the deterioration prediction unit 107 (S321), and updates the deterioration prediction table 135 (S323).

When the activation source is the control unit 103, the storage control unit 105 receives the update data to which the flag is added (S305). The storage control unit 105 determines the type of flag added to the received update data (S307). Then, the storage control unit 105 updates the predetermined table according to the determined flag. That is, when the flag is the deterioration state table 131, the storage control unit 105 updates the deterioration state table 131 (S307). When the flag is the equipment state table 132, the storage control unit 105 updates the equipment state table 132 (S309). When the flag is the road table 133, the storage control unit 105 updates the road table 133 (S311). When the flag is the structure table 134, the storage control unit 105 updates the structure table 134 (S313).

FIG. 10 shows a processing procedure of the error correction processing in step S330. In the error correction process, when the position ID to which the incidental equipment belongs is not uniquely determined in the equipment state table 132, one position ID is specified based on the construction information regarding the incidental equipment, and the position of the equipment state table 132 is determined. The error 1320 may be corrected.

The storage control unit 105 performs the following processing for all the records in the road table 133.

First, the storage control unit 105 determines whether or not the record to be processed of the road table 133 includes under-construction information, that is, whether or not a value other than NULL is set in the under-construction information 1339 (S401).

If there is no under construction information in the under construction information 1339, the storage control unit 105 skips to the next record without performing processing (S401: No).

If the under-construction information 1339 includes the under-construction information (S401: Yes), the storage control unit 105 identifies the position where the construction is performed by the road name 1331 to the position ID 1333, and sets the position ID 1333 as x (S403). ). In the example of FIG. 4, “electrical lighting (new) replacement” and “guardrail repair” are performed at the position ID “7” in which the under-construction information 1339 is set. Therefore, in this example, x=7.

The storage control unit 105 refers to the equipment state table 132, extracts the equipment name 1325 whose position ID 1324 is at the position x, and sets it as A (S405). There may be a plurality of A.

Here, a specific example is shown in FIG. This figure shows an excerpt of some items of some records including records 132A and 132B of the equipment state table 132 before and after the error correction. Hereinafter, description will be given with reference to this figure as well. In FIG. 7A, “road lighting (new)”, “guardrail”, and “communication cable” whose position ID is “7” are A.

The storage control unit 105 refers to the equipment state table 132, extracts the equipment name 1325 in which the position ID 1324 is x-1 and sets it as A-1 (S407). There may be a plurality of A-1s. In the above example, “road lighting (new)”, “post cone”, and “communication cable” whose position ID is “6” are A-1.

The storage control unit 105 refers to the equipment state table 132, extracts the equipment name 1325 at the position where the position ID 1324 is x+1, and sets it as A+1 (S409). There may be a plurality of A+1. In the above example, “road lighting (new)”, “guardrail”, and “communication cable” whose position ID is “8” are A+1.

Next, the storage control unit 105 determines whether or not the under construction information 1339 whose position ID 1333 is x is related to A in the road table 133 (S411). In the above example, it is determined whether the construction performed with the position ID "7" is one of "road lighting (new)", "guardrail", and "communication cable". Here, the under-construction information 1339 is “road lighting (new) electric light replacement” and “guardrail repair”.

If the under-construction information 1339 does not relate to A (S411: No), step S413 is skipped.

When the under-construction information 1339 is related to A (S411: Yes), the storage control unit 105 sets the position error 1320 of the facility whose facility ID 1325 whose location ID is x in the facility state table 132 is A to 0. (S413). This is because if the under-construction information whose position ID is x relates to A, it is determined that A exists in x.

In the example of FIG. 11, since the under-construction information 1339 relates to “road lighting (new)” and “guardrail” of A, the traveling direction reverse-position of the record 132B (“guardrail” with position ID “7”) The error 1320-2 is set to “0”. Before the error correction, “1” was set in the traveling direction reverse-position error 1320-2. This means that the "guardrail" with the position ID "7" may actually exist at the position ID "6". However, it was determined from the construction information that the "guardrail" with the position ID "7" exists at the position ID "7". The above processing is for reflecting this in the equipment state table 132.

Returning to FIG. 10, the storage control unit 105 determines whether or not the under construction information 1339 with the position ID 1333 of x is inconsistent with A-1 or A+1 in the road table 133 (S415). In the example of FIG. 11, the construction “road lighting (new) electric light replacement” and “guardrail repair” performed with the position ID “7” are “road lighting (new)” and “post cone” of A-1. And "communication cable" or A+1 "road lighting (new)", "guardrail", and "communication cable" to determine whether there is a contradiction.

For example, the "guardrail repair" performed at the position ID "7" is inconsistent with the "post cone" of A-1. Because, if the "guard rail" and the "post cone" cannot exist in the same position at the same time, the "post cone" will be placed at the position (position ID "7") where the "guard rail repair" is performed. It cannot exist.

If there is no contradiction in step S415, step S417 is skipped.

If there is the above contradiction in step S415, the storage control unit 105 sets the traveling direction-position error 1320-1 of the equipment having the location ID 1324 of the equipment state table 132 to x and the equipment name 1325 of A-1 to 0, The traveling direction reverse-position error 1320-2 of the equipment whose location ID 1324 of the equipment state table 132 is x and whose equipment name 1325 is A+1 is set to "0" (S415).

In the example of FIG. 11, since there is no “post cone” in the position ID “7”, the traveling direction-position error 1320-1 of the record 132A is not “1”. Therefore, the storage control unit 105 corrects the traveling direction-positional error 1320-1 of the record 132A to "0".

By the above processing, it is possible to correct the positional error of the equipment by using the under construction information.

Next, the extraction unit 109 reads data from each table of the storage unit 130.

FIG. 12 shows a processing procedure of the extraction unit 109.

When the extraction unit 109 is activated, the activation source determination is performed. In this activation source determination, it is determined whether the activation is performed by batch processing or by the control unit 103 (S501).

When the extraction unit 109 is activated by the control unit 103, the extraction unit 109 receives a reference request from the control unit 103 (S503). The extraction unit 109 extracts the requested data from each table (deterioration state table 131, equipment state table 132, road table 133, structure table 134, deterioration prediction table 135) according to the reference request (S505 to S513).

The extraction unit 109 transmits the extracted data to the display control unit 111 and activates the display control unit 111 (S515). At this time, when the reference request includes the display layout identification information, the reference request may be transmitted to the display control unit 111 together with the extracted data.

When the extraction unit 109 is activated by batch processing, the extraction unit 109 extracts data used for batch processing from each table (deterioration state table 131, equipment state table 132, road table 133, structure table 134) (S531 to S531). S537).

The extraction unit 109 transmits the extracted data to the deterioration prediction unit 107 and activates the deterioration prediction unit 107 (S539).

The display control unit 111 generates display screen data for a display screen displayed on the terminal device 3.

FIG. 13 shows a processing procedure of the display control unit 111.

When the display control unit 111 is activated, the data extracted by the extraction unit 109 is acquired (S601).

The display control unit 111 selects a screen layout corresponding to the extracted data (S603). The identification information of the screen layout may be acquired from the extraction unit 109.

The display control unit 111 determines whether or not the equipment layout is included in the screen layout selected in step S603 (S605). If the equipment state is not included (S605: No), the process skips to step S611.

When the equipment state is included (S605: Yes), the following processing is performed for each piece of equipment included in the screen layout. That is, the display control unit 111 determines whether or not a value other than “0” is set in the position error 1320 of the equipment status table 132 for the equipment status included in the screen layout (S607). If a value other than "0" is set, the position ID where the facility exists is expanded by the position error (S609).

For example, as shown in FIG. 25, a case where “guardrail” based on the record 132B is displayed in a screen layout including equipment display will be described as an example. This traveling direction reverse-position error 1320-2 is "1". That is, since this guardrail exists at the position ID “7” or “6”, the position ID may be displayed from “7” alone to span “6” to “7” in step S705.

The display control unit 111 performs steps S607 and S609 for all the equipment included in the screen layout.

The display control unit 111 allocates predetermined data to the screen layout selected in S603 to generate display screen data (S611).

The display control unit 111 transmits the display screen data generated here to the communication unit 101 and activates the communication unit 101 (S613).

As a result, the display screen data is transmitted to the terminal device 3, and the display screen based on the data is displayed on the display device 302.

The deterioration prediction unit 107 predicts a future deterioration state of the infrastructure equipment based on the data extracted from the deterioration state table 131.

FIG. 14 shows a processing procedure of the deterioration prediction unit 107.

The deterioration prediction unit 107 receives the deterioration prediction data extracted for the deterioration prediction from the extraction unit 109 (S801). The deterioration prediction data may be data extracted from the deterioration state table 131, the equipment state table 132, the road table 133, and the structure table 134.

The deterioration prediction unit 107 performs deterioration prediction simulation processing based on the received deterioration prediction data to calculate deterioration prediction data (S803). A known algorithm can be used for the deterioration prediction simulation process, and for example, regression analysis using past deterioration state index data may be performed.

The deterioration prediction unit 107 transmits the calculated deterioration prediction data to the storage control unit 105 and activates the storage control unit 105 (S805).

Next, FIG. 15 shows an outline of a processing procedure in which the infrastructure equipment management system 1 displays each screen described below.

First, the communication unit 101 receives a reference request from the terminal device 3, and performs processing according to the flowchart shown in FIG. 7 (S901).

Next, when the control unit 103 receives the reference request from the communication unit 101, processing is performed according to the flowchart shown in FIG. 8 (S903).

The extraction unit 109 extracts necessary data from each table of the storage unit 130 according to the reference request (S905). For example, the extraction unit 109 acquires data indicating the condition of the road displayed on each screen related to the reference request, data on incidental equipment, data on attributes, and the like.

The display control unit 111 allocates the data extracted by the extraction unit 109 to a predetermined screen layout to generate display screen data (S907). The display screen may have, for example, a layout in which areas indicating road states for each position ID are arranged in the same positional relationship as the actual position ID, as in each screen described later.

The display screen data generated by the display control unit 111 is transmitted to the terminal device 3 via the communication unit 101 (S909).

In the terminal device 3, the communication device 303 receives the display screen data and the screen according to the display screen data is displayed on the display device 302 (S911).

Next, the screen displayed on the terminal device 3 will be described. Each screen may be displayed on the display device 302 based on the display screen data generated by the display control unit 111.

FIG. 16 is a diagram showing a road condition list display screen 500. The road condition list display screen 500 shows a state of roads, which are one-dimensionally arranged infrastructure facilities to be managed. Since the road includes an upstream line (upstream infrastructure facility) and a downstream line (downstream infrastructure facility), the road condition list display screen 500 divides the area indicating the upstream line state and the area indicating the downstream line state. May be. When the up line (upstream infrastructure equipment) and the down line (downstream infrastructure equipment) each include a plurality of lanes (systems), the road condition list display screen 500 separately displays areas indicating the states of the respective lanes. Good.

The road condition list display screen 500 includes up display areas 501a to 503a that display information about up lanes and down display areas 501b to 503b that display information about down lanes provided below the up display areas 501a to 503a.
