In the first embodiment of the present invention applied to the laying work of the water pipe, as shown in FIG. 1, the field worker 110 acquires the construction information and the position information at the moving site 100 and obtains the electronic form 140. Automatically uploaded from a mobile terminal (for example, a tablet terminal) 120, an artificial satellite positioning (GNSS (Global Navigation Data System)) receiver (hereinafter, also simply referred to as a slave) 30, and an electronic form 140 for creation. A cloud server 200 for outputting aggregated data 212 based on the completed construction records 210A-1, 210A-2, ..., 210An, and creating drawing data 226 from the aggregated data 212, and the cloud. The drawing data 226 created by the server 200 is reflected in the mapping system 350 by the site supervisor 340 to form a progress map 360, and the fixed site office 300 equipped with a PC terminal 320 for displaying the progress graph 370. , Is mainly provided.

At the site 100, the electronic form 140 in the mobile terminal 120 is used to create a construction record 210 to improve work efficiency. In addition to the usual check items, photos and location information can be attached to the construction record 210 to add value. The construction record 210 is uploaded to the cloud server 200 one by one, and labor saving is achieved by automatically outputting the aggregated data 212 and the drawing data 226. The site supervisor 340 reflects the output drawing data 226 in the mapping system (comparison of planning line-construction line) 350 to obtain the progress map 360, and outputs the progress rate in the progress graph 370 to visualize the construction progress. Aim.

The location information can be acquired by using the GPS (GNSS) system of the mobile terminal 120 or the GPS (GNSS) receiving system prepared separately. However, when performing progress management based on position information, it is desirable to acquire more accurate position information.

For example, as shown in FIGS. 2 (basic configuration) and 3 (configuration on the slave unit side), for example, a GNSS receiving master unit (also simply referred to as a master unit) 20 is installed in the field office 300, and a positioning signal from the satellite 10 is signaled. The mobile handset 30 that also receives the positioning signal from the satellite 10 is the data for correcting the error via the PC terminal 320, the router 330, and the Internet line I of the field office 300. It is desirable to receive RTCM by communication, recalculate based on the error, and acquire position information by RTK (Real Time Kinematic) positioning method or the like to calculate more correct coordinates.

When the RTK positioning method is applied to the site, the master unit 20 is installed at a fixed point such as the site office 300.

The field worker 110 holds the slave unit 30 at hand and receives the position information NMEA of the receiver at the mobile terminal 120.

The master unit 20 of the site office 300 and the slave unit 30 of the site worker 110 are linked by the Internet line I via each terminal, and the position information of the mobile terminal 120 on the site worker 110 side is corrected to improve the accuracy. Increase.

As illustrated in FIG. 3A, there is no limit to the number of slave units 30A to 30D as long as the master unit 20 installed in the field office 300 can be covered. When the on-site work is performed by a plurality of groups, by supplying the slave unit 30 and the mobile terminal 120 to each group, it is possible to collect information on the construction from each group.

On the other hand, if the site is wide and one master unit cannot cover the target range, install multiple master units (fixed points) (two units 20A and 20B in the figure) as illustrated in Fig. 3 (B). By doing so, the scope of application can be expanded. The number of master units 20 is not limited to one or two, and may be three or more.

According to this RTK positioning method, highly accurate measurement in units of several centimeters is possible.

Hereinafter, the work procedure will be described with reference to FIG.

First, the location information at the site 100 is acquired by utilizing the mobile terminal 120 prepared at the site worker 110. An application for creating an electronic form 140 (referred to as an electronic form application) is installed in the mobile terminal 120 in advance, and location information can be input to one of the items.

FIG. 5 shows the location information acquisition status of the site 100. The field worker 110 places a GNSS receiver (also referred to as an antenna terminal) 30 at the connection portion of the structure, connects the mobile terminal 120 at hand and the antenna terminal 30, acquires the position information of the target, and inside the mobile terminal 120. It is reflected in the electronic form 140 of.

The acquired data for construction management and progress management are the following four items.

(1) Construction information / construction inspection record (standard item): Inspection information such as structure type such as pipe type and diameter, builder, bolt torque, gap amount, etc.

(2) Construction status photo: Construction status photo at the time of construction

(3) Location information: Location information acquired by GPS (preferably RTK positioning or higher) * (1), (2), and (3) are recorded in one electronic form 140 for each connection.

(4) Plan drawing: Plan drawing created before construction

A specific example of the electronic form 140 is shown in FIG. The electronic form 140 is created for each type of line structure used for construction, for each structural member to be constructed, for each joint of the structural member, and for each construction method of the structural member.

Each electronic form 140 is provided with check items required for the target items, and items such as a builder, a construction date and time, photographic information, and location information are prepared in common.

On the electronic form 140 shown in FIG. 6, as shown in the input example in FIG. 7, information on the person performing the construction, information on the structure to be constructed, confirmation items at the time of construction, photographs showing the construction status, and position information are displayed. input. In particular, the input of confirmation items at the time of construction can assist the builder, that is, the on-site worker 110 by setting check boxes, pull-downs, determination of input values, and the like in advance.

After confirming the construction status, this record is uploaded to the cloud server 200. At that time, it is possible to specify the required input items first and set that uploading is not possible if those items are not input. As a result, it is possible to prevent omission of confirmation during construction.

Regarding the input of the position information, it can be automatically taken into the mobile terminal 120 and a numerical value can be input in the corresponding item.

The construction record 210 uploaded to the cloud server 200 can describe the confirmation and approval of the construction supervisors.

The construction record 210 of the site including the location information is systematically stored in the same folder in the cloud server 200 as illustrated in FIG. For example, records of the same builder are stored in order of recording time.

A large number of construction records 210 stored in the folder are regularly automatically aggregated into a single spreadsheet data (also referred to as aggregated data or aggregated table) 212.

However, multiple outputs can be made based on the final output diagram and progress rate.

FIG. 9 shows an example of a state in which a summary table and a laying diagram are created from the output construction record. Specifically, first, every time the site worker 110 installs a structure whose construction status should be confirmed, the construction record 210A-1, 210A-2, 210A-3, using the construction record 210 in the mobile terminal 120, Enter 210A-4, 210A-5, ..., 210A-n, a photograph, location information, and the like. The completed construction record 210 is sequentially uploaded to the cloud server 200 via the mobile line. At this time, the uploaded data is given a data name by a method specified in advance and saved.

Next, from the information of each of the construction records 210, information such as pipe type, joint information, and position information required for the drawing data 226 in the subsequent stage is temporarily aggregated into one data as aggregated data 212. In the aggregated data 212, the code required for drawing creation is output based on the construction record and position information of the check data.

Then, the drawing data 226 of the laying diagram is created based on the drawing creation code.

FIG. 10 shows a state in which a parts diagram is selected from the tabulation table 212. When outputting drawings, based on the aggregated laying structure (pipe) records, the sketches, dimensions, arrows, etc. are automatically calculated by selecting output from the registered drawing first, drawing from the selection from the registration code, or a combination thereof. create. For these schematic drawings, the position and direction are set based on the construction information, the position information and the position information adjacent thereto.

FIG. 11 shows a state in which a laying diagram is created from the tabulation table 212. Construction records and location information are automatically aggregated in aggregation data (spreadsheet data) on a regular basis, and primary processed drawing creation data is output.

Drawings are created based on location information, sketches and attachments are created based on construction records such as diameter, pipe type, and accessories, and these are also related to location information and displayed at appropriate locations. Let me.

Next, based on the drawing creation command automatically output in the summary table 212, the laying diagram is automatically created by using the laying diagram creation program. That is, the cloud server 200 creates a laying diagram creation program from construction information (pipe type, connection method, etc.) and location information. The final output drawing is set as the route and attached information. The processing in the cloud server 200 is automatically performed by, for example, RPA (Robotic Process Automation).

The site supervisor 340 can take in the drawing output to the mapping system 350 and visually grasp the progress of the construction by using the progress map 360 as shown in FIG. Furthermore, it is possible to understand the situation more concretely by comparing it with the planned route map taken in advance.

Here, the layer setting of the mapping system 350 in the progress map 360 is as shown in FIG. The height coordinate z values of the images are all the same. It is desirable that the output drawing is output in separate layers as necessary for the subsequent processing (progress processing).

FIG. 14 shows an example of creating a laying diagram based on the construction records 210A, 210B, 210C input from the mobile terminals 120A, 120B, 120C of the plurality of field workers 110A, 110B, 110C. Each diagram is created from the construction records (position information) input from the mobile terminals 120A, 120B, 120C of each route (each group). On the site supervisor 340 side, each diagram can be displayed in an overlapping manner to manage the overall progress. By changing the presence or absence of display on the mapping system 350, it is possible to check only the individual progress status.

Further, the arrangement extension of the plan drawing created in advance and the construction extension of the laying diagram are compared, the progress rate is calculated on the map, and the progress graph 370 as shown in FIG. 15 is output.

The horizontal axis of the progress graph 370 indicates the construction period. In FIG. 15, the scale is set to be reflected monthly and the graph is set to be reflected weekly.

The left vertical axis is the axis showing the progress length for each period, and the bar graph on the graph is the target. In addition, the amount of progress is calculated for each group or each route, and the progress length of each group (each route) can be confirmed by displaying it in color on the graph.

The right vertical axis shows the achievement rate. The broken line on the graph represents the planned progress rate, and the solid line represents the actual progress rate. If the solid line represents a value higher than the broken line, it means that the construction is proceeding relatively as planned, while if the solid line is below the broken line, it means that the construction is delayed.

The graph of FIG. 15 is a graph that follows all routes, but a similar progress graph can be displayed for each route, which can be used for more detailed progress rate management.

The progress rate R is calculated as shown in FIG. 16 using the following equation (1).

Here, α is the weight coefficient of the work type to reflect the type and material of the pipe (steel pipe, ductile cast iron pipe, etc.) and the joining method (bolt, welding, etc.), L is the planned extension, (x, y, z). Is the coordinates of the installation position, and it is desirable to reflect not only the plane information x and y but also the height information z.

The information that is automatically output is summarized below.

(5) Construction information / construction inspection record list: The construction records uploaded to the cloud server 200 by each route or each group are automatically organized and a list is created.

(6) Line structure arrangement completion drawing (laying diagram): Automatically output a drawing (line diagram) of the section where laying is completed based on information such as position information and pipe type in the list of (1) (schematic diagram). Create drawings by associating symbols such as etc. with location information).

(7) Construction progress status: Compare (4) and (6) and display the construction progress status concretely. The display method is a colored display on the progress map 360, the progress rate R is calculated based on the line length, and the progress graph 370 is output.

As shown in FIG. 17, the data related to the construction work existing in the site office 300 is stored in the same cloud server 200, and can be accessed from the customer 400 or each affiliated company 410 or 420, for example, to facilitate information / material sharing. Can be achieved.

In the first embodiment, the laying drawing was created in the cloud server 200, but when the cloud server 200 and the Internet line I have no margin, as in the second embodiment shown in FIG. It is also possible to perform drawing creation processing on the data processing terminal (PC) 320 of the field office 300.
