Description

The present invention relates to a plastic pipe installation information generation system, a plastic pipe installation information generation method using the system, a computer program for executing the plastic pipe installation information generation system, and a recording medium on which the program is recorded. More specifically, the present invention relates to a plastic pipe installation information generation system that includes at least an electric fusion device that applies heat to an electric heating wire in a fitting body into which a plastic pipe is inserted, fusing the plastic pipe to the fitting body, a mobile terminal carried by the worker performing the fusion, and a work recording device that records information about the fusion work; a computer program for executing the plastic pipe installation information generation method and plastic pipe installation information generation system using the system, and a recording medium on which the program is recorded.

In the past, when constructing plastic pipes and other structures, contractors (workers) would write down the details of the work on paper at the construction site, or after the work was completed, they would create daily reports by entering the necessary information and photographs into a computer in the office. This paperwork process was cumbersome and time-consuming. It was also difficult to easily check various information such as the details of the work at a later date.
In response to this, there is known a support system such as that described in Patent Document 1. While such a support system can improve the efficiency of document preparation work to a certain extent, it does not aim to improve the quality of work during construction, and it has been difficult to guarantee quality.

JP 2012-123589 A

In light of this current situation, the present invention aims to provide a plastic pipe construction information generation system that allows for easy recording and later confirmation of construction details and also improves construction quality, a plastic pipe construction information generation method using this system, a computer program for executing the plastic pipe construction information generation system, and a recording medium on which this is recorded.

To achieve the above objective, the plastic pipe installation information generation system of the present invention is characterized by a configuration including at least an electrofusion device that applies electricity to an electric heating wire in a fitting body into which a plastic pipe is inserted to heat the wire and fuse the plastic pipe to the fitting body, a mobile terminal carried by the worker performing the fusion, and a work recording device that records information about the fusion work, wherein the electrofusion device and the work recording device are capable of communicating with at least the mobile terminal, and include a primary key issuing unit that issues a unique primary key for each fusion work, a work instruction output unit that outputs the work details of one or more of the multiple steps of the fusion work to the mobile terminal as illustrations and/or text, and a process completion data output unit that requests process completion data indicating the completion of the process. a data request unit that requests the portable terminal to read the joint information of the joint body; an electrofusion instruction unit that transmits the read joint information from the portable terminal to the electrofusion device and activates the electrofusion device to start the fusion of the joint body; an electrofusion information request unit that, after the fusion is completed, requests electrofusion information related to the fusion from the portable terminal to the electrofusion device; a position information request unit that requests position information of the joint body where the fusion is completed via the portable terminal; and a construction information generation unit that generates construction information by associating the acquired process completion data, the read joint information, the acquired electrofusion information, and the acquired position information based on the primary key.

According to the above configuration, for one or more of the multiple steps of the fusion work, there is provided a work instruction output unit that outputs the work content of that step to a mobile terminal in the form of illustrations and/or text, and a process completion data request unit that requests process completion data indicating the end of the process, so that the worker can repeatedly carry out and complete the work while checking the work content displayed (output) on the mobile terminal, thereby preventing construction errors and improving construction quality.
The system includes a joint information request unit that requests the reading of joint information of the joint body by the mobile terminal, an electrofusion instruction unit that transmits the read joint information from the mobile terminal to the electrofusion device and activates the electrofusion device to start fusing the joint body, an electrofusion information request unit that, after fusion is completed, requests electrofusion information related to the fusion from the mobile terminal to the electrofusion device, and a position information request unit that requests position information of the joint body where fusion is completed via the mobile terminal. Therefore, the joint information, electrofusion information, and position information can be obtained on the mobile terminal on which the work content output by the work instruction output unit is displayed (output), and further, fusion instructions for the joint body can also be given on the mobile terminal. Therefore, simply by proceeding with the work while checking the work content output by the work instruction output unit on the mobile terminal, the worker can efficiently and accurately obtain the various information required for construction information and can also perform fusion, improving work efficiency.
Furthermore, since the system has a primary key issuing unit that issues a unique primary key for each fusion operation, the various pieces of information acquired in the series of fusion operation steps are identified and stored without being confused with information from other fusion operations.Then, the construction information generating unit generates construction information by associating the acquired process end data, the read joint information, the acquired electrofusion information, and the acquired position information based on the unique primary key for each fusion operation.
In this way, as the worker carries out a series of fusion work in accordance with the display (output) of the mobile terminal, the mobile terminal sequentially acquires various work information that is distinguished from other fusion information, and the acquired various work information is associated with a primary key to generate construction information, making it easy to record the construction details and check them later, and also enabling improvement in quality during construction.

In the above configuration, the process completion data request unit may include an image request unit that requests, for one or more of the processes, photographed images of the work area in that process as the process completion data. This allows users to sequentially obtain photographed images of the work area in that process as process completion data simply by following the display (output) on the mobile device, making it easier to record the construction details.

Furthermore, in this configuration, the process completion data request unit may determine the end of a process when the image request unit acquires the captured image for that process, and the work instruction output unit may output the work content of the next process to the mobile device as illustrations and/or text. Since the end of a work process is determined by the acquisition of a captured image and the process proceeds to the next work process, the worker can acquire captured images for each process without missing anything simply by working according to the work content.

The process completion data request unit preferably includes a previous process completion confirmation unit that confirms whether the process prior to the start of fusion has been completed normally. By confirming whether the work process prior to the start of fusion has been carried out correctly, it is possible to eliminate imperfections or deficiencies in the previous process that could cause poor fusion (abnormalities), further improving the quality of the work (fusion quality) during construction.

The work recording device may also have a quality judgment unit that judges the quality of the work in that process based on the captured images. Because the necessity of the work is judged based on the captured images, it becomes easier to confirm the work content and judge its quality, and the accuracy of the judgment is improved. As a result, workers are encouraged to redo insufficient work, and more appropriate and better work is selected and moved on to the next process (work), thereby further improving quality.

In such cases, it is preferable to further provide a photography information adding unit that adds photography date and time information and photography location information to the photographed image. By adding (linking) this information to the photographed image, the credibility of the record is increased and it is also possible to prevent tampering with the record by replacing images, etc. Furthermore, it is also possible to easily check the photographed image at a later date based on this information.

The work recording device may also preferably have a fusion status analysis unit that analyzes the fusion status based on the acquired electrofusion information. During each step of the work prior to fusion or during the fusion process, slight deficiencies in the accuracy of the work content or the amount of work may occur due to factors such as the worker's experience and ability, or the weather. If such deficiencies occur, the worker may proceed sequentially, believing that each step has been completed. Furthermore, it is possible that the electrofusion device may complete the fusion without detecting a fusion error. Therefore, by analyzing the fusion status based on the electrofusion information acquired after fusion is completed, the fusion status can be alerted to the worker and reconfirmed if, for example, unstable or unusual values are detected. This further improves construction quality. The fusion status is analyzed, for example, by comparing it with a preset threshold.

The image requesting unit may also request photographed images of the end of the plastic pipe after it has been cut, the marked line on the end of the pipe, the cut surface of the end of the pipe, the state of fixation between the plastic pipe and the fitting body, and the indicator on the fitting body after fusion is complete. These photographed images show the results of the work processes of cutting, marking the cutting length, cutting, fixing, and completing fusion, and are likely to be affected by the quality of the fusion work (construction). Therefore, acquiring these photographed images makes it easier to record the construction details and to check them later. Furthermore, determining the quality of the work in each process based on these photographed images also makes it possible to assess the quality of the construction work.

The above configuration may further include a positioning device that uses GNSS to determine the position, and the position information requesting unit may acquire the position information from the positioning device. GNSS (Global Navigation Satellite System) provides three-dimensional position information, including latitude, longitude, and altitude, in units of a few centimeters, allowing the buried location to be determined with high accuracy. Therefore, for example, by acquiring this information together with the position information of manholes, gas pipes, etc., the distance from the plastic pipe and fittings becomes clear, enabling improved maintenance after construction. Furthermore, the process completion data requesting unit may include a weather data requesting unit that requests weather data during the fusion work.

In the above configuration, the work recording device may have a construction information output unit that outputs the construction information, and the construction information output unit may have a mapping unit that maps the construction location on a map based on the location information. The construction information output unit may also have a report output unit that outputs a report based on the generated construction information. As described above, as the worker proceeds with the fusion work according to the display on the mobile device, the generated construction information is generated in which the above-mentioned various information is associated (linked) by a unique primary key for each fusion work. Therefore, upon completion of the work, mapping or reports such as checklists or daily work reports can be output, making it easy to record the construction details and check them later.

The process completion data requesting unit may include an image requesting unit that requests photographed images of the work area in one or more of the processes as the process completion data, and may further include a photographic information assigning unit that assigns photographic date and time information and photographic location information to the photographed images, and the construction information output unit may further include a photographed image output unit that outputs the photographed images based on the photographic date and time information and/or the photographic location information. This allows multiple photographed images to be compiled (organized) and output by photographic date and time or photographic location (construction site), including photographed images taken during one or more of the multiple processes of the fusion work, as well as photographed images taken by the system outside the fusion work (such as before the start or completion of the fusion work), making it even easier to check the construction details.

To achieve the above objective, the plastic pipe construction information generation system of the present invention is characterized in that, in a plastic pipe construction information generation method using the plastic pipe construction information generation system described above, a primary key issuance step for issuing a unique primary key for each fusion work, a work instruction output step for outputting the work content of one or more of the multiple processes of the fusion work to the mobile terminal as illustrations and/or text, a process completion data request step for requesting process completion data indicating the completion of the process, a joint information request step for requesting the mobile terminal to read joint information of the joint body, and The method includes an electrofusion instruction step of transmitting the joint information from the mobile terminal to the electrofusion device, activating the electrofusion device and starting the fusion of the joint body; an electrofusion information request step of requesting electrofusion information related to the fusion from the mobile terminal to the electrofusion device after the fusion is completed; a position information request step of requesting position information of the joint body where the fusion is completed; and a construction information generation step of generating construction information by associating the acquired process completion data, the read joint information, the acquired electrofusion information, and the acquired position information based on the primary key.

In the above configuration, it is preferable to further include a previous process completion confirmation step, prior to the joint information request step, for confirming whether the previous steps have been completed normally. Furthermore, the electrofusion information request step may include a fusion status analysis step for analyzing the fusion status based on the electrofusion information.

The above-described plastic pipe construction information generation system is realized by a computer program for causing a computer to execute the system, and this computer program is recorded on a recording medium.

The features of the plastic pipe construction information generation system, plastic pipe construction information generation method using the system, and computer program for executing the plastic pipe construction information generation system according to the present invention make it easy to record construction details and check them later, and also enable improved quality during construction.

Next, the present invention will be described in more detail with reference to the accompanying drawings where appropriate.
(Overall system configuration)
As shown in Fig. 1, a plastic pipe construction information generating system 1 according to the present invention generally includes at least an electrofusion device 2 that fuses a plastic pipe 101 and a joint body 102 of an electrofusion joint 100, a mobile terminal 3 carried by a worker performing the fusion, and a work recording device 4 that records information about the fusion work. In this embodiment, the plastic pipe construction information generating system 1 further includes a positioning device 5 that measures the position of the construction site. As shown in Fig. 1, during work, the worker holds the antenna 51 of the positioning device 5 near the joint body 102 to be constructed and operates the mobile terminal 3. The work recording device 4 also serves as a server and is connected to user terminals (computers) 9 of relevant parties, such as the construction owner and contractor, via the Internet or the like.

(Electrofusion joint 100)
As shown in FIG. 2 , the joint body 102 of the electrofusion joint 100 has a heating wire 103 on its inner surface and a terminal protrusion 104 on its outer surface. A terminal pin 105 that connects to the heating wire 103 is provided inside the terminal protrusion 104. Therefore, by attaching the connector 2c of the electrofusion apparatus 2 to the terminal protrusion 104, the heating wire 103 can be energized via the terminal pin 105. A barcode 106 containing joint information is affixed to the joint body 102. An indicator 107 is formed near (above) the heating wire 103 of the joint body 102. The indicator 107 protrudes from the outer surface of the joint body 102 due to melting of the resin caused by electrofusion. The barcode 106 is not limited to being affixed to the joint body 102. It may also be, for example, a card-like object on which the barcode 106 is printed, attached to the joint body 102, or packaged together with the joint body 102.

(Electrofusion device 2)
1 and 2, the electrofusion apparatus 2 generally includes a power supply unit 2a that supplies power to a main body 20, and a connector 2c connected via a fusion cable 2b. The main body 20 includes a first communication means 21 that can communicate with the mobile terminal 3, an electrofusion control unit 22 that monitors and controls electrofusion, and a recording unit 23 that records information about the electrofusion. The power supply unit 2a may be an external power source or a battery built into the electrofusion apparatus 2.

Here, a wireless communication means (interface) such as Bluetooth (registered trademark) is used as the first communication means 21. Of course, the communication means is not particularly limited as long as it is possible to send and receive data, such as other wireless communication means such as the Internet or a direct wired connection. Of course, considering workability, a wireless communication means is preferable as the first communication means 21.

The electrofusion control unit 22 initiates and controls electrofusion via the first communication means 21 based on instructions from the electrofusion instruction unit 65 of the mobile device 3, which will be described later. Furthermore, the recording unit 23 records electrofusion information for each fusion operation as a fusion history, including information about the joint, such as the joint manufacturer, nominal diameter, and serial number, as well as information about the fusion, such as the voltage value, current value, and time during fusion. This fusion history is transmitted to the mobile device 3 via the first communication means 21 as electrofusion information related to fusion, based on instructions from the electrofusion information request unit 66.

(Mobile terminal 3)
As shown in Figure 3(a), the hardware configuration of the mobile terminal 3 generally includes a first communication means 31 capable of communicating with the electrofusion apparatus 2, a second communication means 32 capable of communicating with the work recording device 4 (described later), a photographing means 33 for photographing the work location and work status of the fusion work, an input means 34 for inputting work information about the fusion work, a storage means 35 for storing photographed images and input data, a display means 36 for displaying images and data, a location information acquisition means 37 for acquiring location information of the work site, and a mobile terminal control means 38 for controlling these means, all of which are connected by an internal bus 39. These means work together to operate the software. The mobile terminal 3 may be a smartphone, a tablet, a laptop, or other portable information processing device.

Here, the first communication means 31 of the mobile terminal 3 is the same communication means (Bluetooth (registered trademark)) as the first communication means 21 of the electrofusion apparatus 2. Furthermore, the second communication means 32 is, for example, a wireless communication means such as the Internet. These communication means 31, 32 are not particularly limited as long as they are capable of sending and receiving data. Furthermore, the imaging means 33 is a camera capable of taking photographs (still images) and videos. The camera may be built into the mobile terminal 3 or an external camera connected via a USB cable or the like. Note that, in the present invention, "captured images" are not limited to still images (photographs), but also include videos (including audio) that can be captured by a camera. Furthermore, still images or videos may be selected depending on the communication conditions, etc.

The input means 34 is composed of a touch panel, operation buttons, keyboard, etc., and transmits inputs made by the worker to the mobile terminal control means 38. The storage means 35 is composed of memory such as ROM and RAM, and a storage device such as an HDD, and stores software as well as data such as captured images and input data. Note that external storage media such as USB (Universal Serial Bus/registered trademark) memory and SD memory cards may also be used as the storage device for the storage means 35. The display means 36 is composed of a touch panel such as an LCD display or organic EL display, and appropriately displays the operation screen, various data, and judgment results. The mobile terminal control means 38 is equipped with a CPU. In this embodiment, the position information acquisition means 37 acquires position information of the construction site (the location where the fitting body 102 is buried) via the positioning device 5.

As shown in Figure 3(b), the software configuration of the mobile terminal 3 roughly includes a work instruction output unit 61, a primary key issuing unit 62, a process completion data request unit 63, a joint information request unit 64, an electrofusion instruction unit 65, an electrofusion information request unit 66, a position information request unit 67, a construction information generation unit 68, and an imaging information assignment unit 69.

The work instruction output unit 61 outputs the work content of one or more of the multiple fusion work steps to the display means 36 as illustrations and/or text. This reduces work errors and improves construction accuracy. The primary key issuing unit 62 issues a unique primary key for each fusion work.

The process completion data request unit 63 requests process completion data indicating the end of a process. In this embodiment, the process completion data request unit 63 includes an image request unit 63a that requests captured images of the work site for one or more processes as process completion data, and a weather data request unit 63b that requests weather data during the fusion work. The image request unit 63a requests captured images of the pipe end 101a after the end of the plastic pipe 101 is cut, the marked line 108 on the pipe end 101a, the cut surface 101b of the pipe end 101a, the fixed state between the plastic pipe 101 and the fitting body 102, and the indicator 107 on the fitting body 102 after fusion is complete. The process completion data request unit 63 also includes a previous process completion confirmation unit 63c that confirms whether the process up to the start of fusion has been completed.

The joint information request unit 64 requests the reading of the barcode 106. The electrofusion instruction unit 65 transmits the data (joint information) of the read barcode 106 to the electrofusion device 2, which then activates the electrofusion device 2 and begins fusing the joint body 102. After fusion is complete, the electrofusion information request unit 66 requests electrofusion information (fusion history) related to the fusion from the electrofusion device 2. The position information request unit 67 requests position information for the joint body 102 where fusion is complete. The construction information generation unit 68 associates, using a primary key, the process completion data, joint information, fusion history, and position information obtained from each work process (described below) to generate construction information for each fusion work unit. The imaging information assignment unit 69 assigns imaging date and time information and imaging position information to the images of the work area in each process that are captured as process completion data.

(Work recording device 4)
4(a), the hardware configuration of the server serving as the work recording device 4 generally comprises a control means 41 equipped with a CPU, a storage means 42 equipped with a memory and a storage device, and a communication means 43 capable of communicating with other devices via the Internet, all of which are connected by an internal bus 44. Data can be sent and received with the mobile terminal 3 and other information processing devices (personal computers) via the communication means 43. Of course, input means such as a mouse and a keyboard and display means such as a monitor may also be provided.
As shown in FIG. 4B, the software configuration of the work recording device 4 includes a construction information output unit 71 that outputs construction information that associates process completion data, joint information, electrofusion information (fusion history), and location information acquired by the mobile terminal 3; a quality determination unit 72 that determines the quality of the work in the process based on the captured image; and a fusion status analysis unit 73 that analyzes the fusion status based on the electrofusion information. The construction information output unit 71 includes a mapping unit 71a that maps the construction location on a map based on the location information and a report output unit 71b that outputs various reports based on the generated construction information. Examples of reports include checklists, daily work reports, and fusion history lists. Furthermore, the construction information output unit 71 includes a captured image output unit 71c that outputs captured images based on the shooting date and time information and/or shooting location information assigned by the shooting information assigning unit 69.

(Positioning device 5)
In this embodiment, location information from the Global Navigation Satellite System (GNSS) is used as the location information for the construction site. The location measurement device 5 includes an antenna 51 and a transceiver (not shown) that receives the location information measured by the antenna 51 and transmits it to a server. The location information measured by the antenna 51 is stored in a location information server (not shown) via the transceiver, and the location information request unit 67 of the mobile terminal 3 acquires the location information stored in the location information server via the second communication means 32 (Internet). GNSS provides three-dimensional location information, including latitude, longitude, and altitude, in units of several centimeters, allowing for highly accurate determination of the buried location. Therefore, by acquiring this information together with location information for manholes, gas pipes, etc., it is possible to accurately determine the distance between water pipes and other buried objects. Furthermore, for water supply pipes, it is also possible to determine the buried location information at the public-private boundary.

(Resin pipe construction information generation step)
Next, a procedure for generating resin pipe installation information will be described.
As shown in Figures 5A-C, during construction, the worker performs work steps (K1-K15) consisting of basic information registration, cutting, cutting length marking, cutting, cleaning, fixing, weather registration, confirmation of completion of previous process, fusion data input, fusion start, fusion completion, cooling, location information acquisition, fusion history reading, and work confirmation. At each step, the worker performs the necessary work and inputs necessary information and photographs based on instructions displayed on the smartphone (mobile terminal 3). In this way, construction information is generated and accumulated along with the construction work of the plastic pipe, improving work efficiency and preventing construction errors.

1) Basic information registration process (K1)
The work instruction output unit 61 first displays input/selection items such as the construction company, site manager, contractor, project name, and construction location on the touch panel (display means 36). Next, the work instruction output unit 61 displays input/selection items such as the joint number of the joint to be constructed, the construction date, nominal diameter, generator model and voltage, EFC model, and whether or not normal operation has been confirmed, as work information for the fusion work. After completing these input/selection items and the worker taps the "OK" icon, the process completion data request unit 63 determines that the process is complete, and transmits the input data to the work recording device 4 via the second communication means 32 (Internet), where it is stored in the memory unit 42. At this time, the primary key issuing unit 62 generates an information table in memory 35 with a primary key, as shown in FIG. 6 . This primary key is a unique value that distinguishes the fusion work from other joints. The above input data is stored in the information table in memory 35 by the construction information generation unit 68. Various data generated in the following work processes are also stored in an information table to which the same primary key is assigned by the construction information generating unit 68.

In addition to the above data input, the smartphone 3 is able to communicate with the electrofusion device 3 via the first communication means 21, 31 (Bluetooth), and is also able to establish a connection with the work recording device 4 (server) via the second communication means 23 and communication means 43 (Internet).

2) Cutting process (K2)
Next, the work instruction output unit 61 outputs the work content of the cutting process as illustrations and text to the touch panel 36, as shown in Figure 7(a). Then, the worker cuts the end of the plastic pipe to be installed while checking the smartphone 3. After completing the cutting, even if the worker taps the "OK" icon, the process completion data request unit 63 does not determine that the process is complete.

In this process, the image request unit 63a requests a photographed image of the pipe end after the end of the plastic pipe 101 has been cut as process completion data. In this case, the work instruction output unit 61 displays a "camera" icon on the touch panel 36, as shown in FIG. 7(a). When the worker taps the "camera" icon and photographs the pipe end using the camera (photography means 33) on the smartphone 3, the image request unit 63a acquires the photographed pipe end image, and the construction information generation unit 68 stores the photographed pipe end image in an information table in the memory, etc. 35. Here, in this embodiment, the photographing information assignment unit 69 assigns photographing date and time information and photographing location information for the pipe end image to the image. For example, the date and time information of the smartphone 3 at the time of photographing and the location information determined by the positioning device 5 are linked to and recorded with the photographed image, thereby assigning this information to the photographed image. The construction information generation unit 68 stores the photographing date and time information and photographing location information together with the photographed pipe end image in an information table in the memory, etc. 35. The date and time information may be obtained via the Internet, and the location information may be GPS location information built into the smartphone 3.

When the worker taps the "OK" icon, the process completion data request unit 63 determines that the process is complete and transmits the captured pipe end image via the Internet 32 along with the primary key of the information table storing the image's date and time information and location information, to the work recording device 4, where it is stored in the memory unit 42. In this way, the worker cannot proceed to the next process without taking a photo, preventing work (process) and data (information) leaks. Furthermore, because the finished cutting work performed by the worker is always saved (recorded) as an image, it can also be used as work record (evidence). Moreover, because the captured image is assigned (linked, associated) with the image's date and time information and location information, tampering with the image, for example, by using images taken at another site, is prevented, increasing the credibility of the work record. The same applies to the following work processes that require photography.

As shown in FIG. 7(a), the work instruction output unit 61 displays a "?" icon along with the work content. When the worker taps the "?" icon, the work instruction output unit 61 displays more detailed work content, such as key points and precautions for the work. This also applies to the following processes.

3) Cutting length marking process (K3)
Next, as shown in Figure 7(b), the work instruction output unit 61 outputs the work content of the marking process in the form of illustrations and text to the touch panel 36 of the smartphone 3. While checking the smartphone 3, the worker measures the specified insertion length from the pipe end and writes a reference line at a specified position on the pipe surface. Even if the worker taps the "OK" icon after writing the reference line, the process completion data request unit 63 does not determine that the process is complete.

In this process, the image request unit 63a requests a captured image of the vicinity of the marked line as process completion data. In this case, the work instruction output unit 61 displays a "camera" icon on the touch panel 36, as shown in FIG. 7(b). When the worker taps the "camera" icon and takes a photo of the vicinity of the marked line 108 using the camera 33 of the smartphone 3, the image request unit 63a acquires the captured image of the vicinity of the marked line, and the construction information generation unit 68 stores the captured image of the vicinity of the marked line, as well as the image's capture date and time information and capture location information, in an information table in the memory, etc. 35. When the worker then taps the "OK" icon, the process completion data request unit 63 determines that the process is complete and sends the captured image of the vicinity of the marked line, as well as the image's capture date and time information and capture location information, along with the primary key, via the Internet 32 to the work recording device 4, where they are stored in the memory unit 42. This ensures that the position of the marked line entered by the worker is saved (recorded) as an image.

4) Cutting process (K4)
Next, as shown in Figure 7(c), the work instruction output unit 61 outputs the work content of the cutting process in the form of illustrations and text to the touch panel 36 of the smartphone 3. The worker scribes the surface of the pipe end from the pipe end to the marked line while checking the smartphone 3. After cutting, even if the worker taps the "OK" icon, the process completion data request unit 63 does not determine that the process is complete.

In this process, the image request unit 63a requests a captured image of the area near the cut area as process completion data. In this case, the work instruction output unit 61 displays a "camera" icon on the touch panel 36, as shown in FIG. 7(c). When the worker taps the "camera" icon and takes a photo of the area near the cut area using the camera 33 of the smartphone 3, the image request unit 63a acquires the captured image of the cut area, and the construction information generation unit 68 stores the captured image of the cut area, as well as the image's date and time of capture and location information, in an information table in the memory, etc. 35. When the worker then taps the "OK" icon, the process completion data request unit 63 determines that the process is complete, and transmits the captured image of the cut area, as well as the image's date and time of capture and location information, along with the primary key, via the Internet 32 to the work recording device 4, where they are stored in the memory unit 42. This ensures that the finished cut work by the worker is saved (recorded) as an image.

5) Cleaning process (K5)
Next, the work instruction output unit 61 outputs the cleaning process details in illustrations and text to the touch panel 36 of the smartphone 3. The worker cleans the cutting surface and the inner surface of the joint body while checking the smartphone 3. After cleaning, when the worker taps the "OK" icon, the process completion data request unit 63 determines that the process is complete, and the construction information generation unit 68 stores the cleaning completion data in an information table in the memory 35. In addition, the cleaning completion data is transmitted to the work recording device 4 together with the above-mentioned primary key via the Internet 32 and stored in the storage unit 42.

6) Fixing process (K6)
Next, the work instruction output unit 61 outputs the work content of the fixing process as illustrations and text to the touch panel 36 of the smartphone 3, as shown in Figure 8 (a). The worker inserts the pipe into the fitting body up to the marked line while checking the smartphone 3 and fixes it with a clamp. After fixing, even if the worker taps the "OK" icon, the process completion data request unit 63 does not determine that the process is complete.

In this process, the image request unit 63a requests a captured image of the fixed portion as process completion data. In this case, the work instruction output unit 61 displays a "camera" icon on the touch panel 36, as shown in FIG. 8(a). When the worker taps the "camera" icon and takes a photo of the fixed portion using the camera 33 of the smartphone 3, the image request unit 63a acquires the captured image of the fixed portion, and the construction information generation unit 68 stores the captured image of the fixed portion, as well as the image's date and time of capture and location information, in an information table in the memory, etc. 35. When the worker then taps the "OK" icon, the process completion data request unit 63 determines that the process is complete and transmits the captured image of the fixed portion, as well as the image's date and time of capture and location information, along with the primary key, via the Internet 32 to the work recording device 4, where they are stored in the memory unit 42. This ensures that the finished product of the worker's fixing work is saved (recorded) as an image.

7) Weather registration process (K7)
Next, in this process, the weather data requesting unit 63b requests weather data at the time of the fusion work as process completion data. In this case, for example, the work instruction output unit 61 displays weather options (icons) on the touch panel 36. When the worker taps the "Weather" icon and then the "OK" icon, the process completion data requesting unit 63 determines that the process is complete, and the construction information generating unit 68 stores the weather data in an information table in the memory 35. The weather data is also transmitted to the work recording device 4 via the Internet 32 along with the above-mentioned primary key and stored in the storage unit 42. Note that weather data can also be obtained via the Internet for weather registration.

8) Pre-process completion confirmation process (K8)
After the weather registration step (K7) is completed, the previous step completion confirmation unit 63c confirms whether all previous steps (K1 to K7) have been completed normally. In this case, for example, the previous step completion confirmation unit 63c causes the quality determination unit 72 of the work recording device 4 (server) to compare the captured images and information stored (saved) in the previous steps with the normal state (healthy data) and determine whether the work was successful.

However, quality control at construction sites is largely the responsibility of the contractor, and until now, there has been no way for the client, such as a local government waterworks bureau, and the construction company to effectively and efficiently share construction information, meaning that both parties have often had to check the quality of the fusion joint after the fact. For example, if a leak occurs from the fused joint of a fitting, one possible cause could be that the cutting length on the pipe side was not marked properly, causing the fitting to not be inserted properly and resulting in insufficient fusion.

In this embodiment, the quality assessment unit 72 compares the captured images and information with the normal state via the previous process completion confirmation unit 63c to determine the quality of the work. For example, during the cutting length marking process (K3), it determines whether the specified insertion length was measured from the pipe end and the marked line was marked at the specified position on the pipe surface based on an image of the vicinity of the marked line captured. Furthermore, during the fixing process (K6), it determines whether the pipe was inserted into the fitting body up to the marked line position and fixed based on an image of the fixing portion captured. In this way, since it determines whether the previous process (work) was completed normally before the start of fusion, construction (work) defects that could cause leaks, etc., as described above, can be detected and prevented before fusion, improving construction quality. Furthermore, since the work recording device 4 functions as a server and is connected to user terminals (computers) 9 of related parties, such as the contractor and the contractor, via the Internet or other means, it is possible to check the status of the previous process in real time.

The pass/fail judgment unit 72 then stores each judgment result in the memory unit 42 and transmits it to the previous process completion confirmation unit 63c. If any of the judgment results are NG, the previous process completion confirmation unit 63c, for example, displays the judgment result on the touch panel 36 of the smartphone 3 and also displays a screen of the work process that was judged NG, urging the worker to redo the work. On the other hand, if all judgment results are OK, the process completion data request unit 63 determines that the process is complete, and the construction information generation unit 68 stores the judgment results in an information table in the memory, etc. 35.

8) Fusion data input process (K9)
Next, in this process, the joint information request unit 64 requests the reading of a barcode as joint information affixed to the joint body 102. In this case, for example, the work instruction output unit 61 displays a "camera" icon on the touch panel 36, as shown in FIG. 8(b). When the worker taps the "camera" icon and photographs the barcode with the camera 33 of the smartphone 3, the joint information request unit 64 reads the joint information from the barcode, and the construction information generation unit 68 stores the read joint information in an information table in the memory 35. As a result, the work results such as images in each of the above work processes and the joint information are associated (linked) via the primary key. Thereafter, when the worker taps the "OK" icon, the process completion data request unit 63 determines that the process is complete.

The electrofusion instruction unit 65 also transmits the read joint information to the electrofusion control unit 22 of the electrofusion device 2 via Bluetooth 21, 31. The electrofusion control unit 22 references the fusion conditions for each joint body that are pre-stored in the recording unit 23. This identifies the fusion conditions for the joint body to be fused in the next process, making it possible to issue fusion instructions (operations) from the smartphone 33.

9) Fusion process (K10)
Next, in this step, the electrofusion instruction unit 65 activates the electrofusion control unit 22 to start fusion. In this case, for example, the work instruction output unit 61 outputs a "start fusion" icon to the touch panel 36 of the smartphone 3. When the worker taps the "start fusion" icon, the electrofusion instruction unit 65 displays the fusion time based on the joint information read on the touch panel 36 and activates the electrofusion control unit 21 of the electrofusion device 2 to start fusion.

The electrofusion control unit 21 starts fusion and also starts generating a fusion history as information about the electrofusion. This fusion history includes a unique job sequence number for each fusion job, the fusion start date and time, the joint information (barcode data) received by the joint information request unit 63 in the previous process, as well as information such as the joint manufacturer name, product type, and nominal diameter. Additionally, the fusion history sequentially records the control voltage value, fusion time, ambient temperature, joint resistance value, actual current flow time, input/output voltage (maximum and minimum), output current (maximum and minimum), cumulative heat, and fusion results as fusion results according to the progress of fusion. This allows the read joint information and fusion history to be associated for each joint being fused by the job sequence number.

The electric fusion control unit 21 also monitors the fusion status immediately after fusion begins, and if it detects an abnormality during fusion, it halts fusion. At this time, the work instruction output unit 61 displays an abnormality (fusion stop) warning on the touch panel 36. The recording unit 23 also records the details of the detected abnormality (fusion error) along with the above-mentioned fusion results, and generates this as a fusion abnormality history. Here, the fusion abnormality history refers to the above-mentioned fusion history to which the details of the detected abnormality (fusion error) have been added.

Then, the electrofusion control unit 21 transmits the generated fusion abnormality history to the mobile terminal 3 via the first communication means 21. The transmitted fusion abnormality history is stored in an information table in the memory, etc. 35 by the construction information generation unit 68, and is also transmitted together with the primary key to the work recording device 4 via the Internet 32 and stored in the memory unit 42. This allows the details of the abnormality (fusion error) to be shared with the worker and relevant parties such as the contractor and contractor who are connected to the work recording device 4 via the Internet, etc., making it easier to understand the situation and confirm the work content.

The work instruction output unit 61 then displays a comment field on the touch panel 36, allowing the operator to enter details of the remedial action taken in response to the abnormality (fusion error). When the operator enters the details of the remedial action in the comment field and taps the "OK" icon, the process completion data request unit 63 determines that the process is complete, and the construction information generation unit 68 stores the entered details of the remedial action in an information table in the memory, etc. 35. The process completion data request unit 63 also displays a warning screen on the touch panel 36, such as a screen showing the first work step, to prompt the operator to start the work over again. If an abnormality is detected during fusion and the fusion is aborted, the plastic pipe, including the joint, is generally cut and discarded, and the process is restarted from the beginning. In this way, information that fusion was not completed normally can be recorded, and the operator is prompted to start the work over again without having to bury the joint, thereby improving construction quality.

On the other hand, if the electrofusion control unit 21 does not detect an abnormality (fusion error), it continues fusion for the specified time. In this way, electrofusion can be performed for the specified fusion time by operating the smartphone 3 without operating the electrofusion device 2, and the fusion status (results) are generated as a fusion history. After the fusion time has elapsed, when the operator visually checks the fusion status and taps the "OK" icon, the process completion data request unit 63 determines that the process is complete, and the electrofusion information request unit 65 requests from the electrofusion control unit 21 the operation serial number and some of the fusion history items (data) of the fusion history of the fused joint, such as the fusion start date and time, control voltage value, fusion time, joint resistance value, ambient temperature, actual current application time, input/output voltage (maximum and minimum), and output current (maximum and minimum). The construction information generation unit 68 then stores the returned operation serial number and some of the fusion history items (data) in an information table in the memory, etc. 35.

10) Fusion completion process (K11)
Next, as shown in Fig. 8(c) , the work instruction output unit 61 outputs the work content of the fusion completion process in the form of illustrations and text to the touch panel 36 of the smartphone 3. The worker checks the smartphone 3 to confirm that the indicator 107 is raised. After confirmation, even if the worker taps the "OK" icon, the process completion data request unit 63 does not determine that the process is complete.

In this process, the image request unit 63a requests a captured image of the area around the indicator 107 (joint body) as process completion data. In this case, the work instruction output unit 61 displays a "camera" icon on the touch panel 36, as shown in FIG. 8(c). When the worker taps the "camera" icon and takes a photo of the area around the indicator 107 using the camera 33 of the smartphone 3, the image request unit 63a acquires the captured indicator image, and the construction information generation unit 68 stores the captured indicator image, along with the date and time information and location information for the photo, in an information table in the memory, etc. 35. When the worker taps the "OK" icon, the process completion data request unit 63 determines that the process is complete, and transmits the captured indicator image, along with the date and time information and location information for the photo, via the Internet 32 to the work recording device 4 along with the above-mentioned primary key, and these are stored in the memory unit 42. Therefore, the finished electrofusion is always saved (recorded) as an image.

Furthermore, in this embodiment, the process completion data request unit 63 transmits the work sequence number and some of the fusion history items (data) together with the above-mentioned primary key via the Internet 32 to the work recording device 4, where they are stored in the memory unit 42. Here, for example, the memory unit 42 is pre-stored with thresholds set for some of the fusion history data items. The fusion status analysis unit 73 then compares the received some of the fusion history items with the set thresholds to analyze the fusion status.

At each stage of the work up to fusion, slight shortcomings in the accuracy of the work content or the amount of work may occur due to factors such as the worker's experience and ability, the weather, etc. The worker may proceed with the process sequentially, believing that each task has been completed, and may complete the process without detecting a fusion error during fusion. Therefore, in this embodiment, the fusion status analysis unit 73 analyzes the fusion status by comparing some items in the fusion history with thresholds, and stores the analysis results in the memory unit 42 and transmits them to the process completion data request unit 63.

If the analysis results are unfavorable, the process completion data request unit 63 will, for example, display the analysis results on the touch panel 36 to prompt the worker to check the situation. On the other hand, if the analysis results are favorable, the process completion data request unit 63 will determine that the process is complete, and the construction information generation unit 68 will store the determination result in an information table in the memory, etc. 35. In this way, for example, if unstable values or values that differ from normal are detected in some items of the fusion history data immediately after fusion, the worker will be alerted to the fusion status and will be prompted to reconfirm and review the work, thereby further improving construction quality.

11) Cooling process (K12)
Next, the work instruction output unit 61 outputs the work content of the cooling process to the touch panel 36 of the smartphone 3 using illustrations and text. For example, the cooling time is displayed based on the joint information read on the touch panel 36. The worker performs cooling for the displayed cooling time while checking the smartphone 3, and enters the cooling completion time (cooling time) in the joint body 102. After the cooling time has elapsed, when the worker taps the "OK" icon, the process completion data request unit 63 determines that the process is complete, and the construction information generation unit 68 stores the cooling completion data in an information table in the memory 35. In addition, the data indicating that cooling has been completed is transmitted to the work recording device 4 together with the primary key via the Internet 32 and stored in the storage unit 42.

12) Location information acquisition process (K13)
Next, in this process, the position information request unit 67 requests the position information of the joint body 102 for which welding has been completed as process completion data. In this case, for example, the work instruction output unit 61 outputs a "positioning" icon to the touch panel 36 of the smartphone 3. When the worker taps the "positioning" icon, the position information request unit 67 acquires the position information acquired by the antenna 51 via the Internet 32, and the construction information generation unit 68 stores the acquired position information in an information table in the memory 35. As a result, the work results such as images in each of the above work processes, the joint information, and the position information are associated (linked) via the primary key. Then, when the worker taps the "OK" icon, the process completion data request unit 63 determines that the process is complete, and transmits the position information together with the primary key to the work recording device 4 via the Internet 32, where it is stored in the memory 42. It is also possible to record the depth from the ground surface using GNSS position information by entering the buried depth before tapping the "positioning" icon.

13) Fusion history acquisition step (K14)
Next, in this step, the electrofusion information request unit 66 requests electrofusion information (fusion history) from the electrofusion device 2 as process completion data. In this case, for example, the work instruction output unit 61 outputs a "history capture" icon to the touch panel 36 of the smartphone 3. When the worker taps the "history capture" icon, the electrofusion information request unit 66 requests all items (data) of the fusion history generated in the previous fusion step K10 from the electrofusion control unit 21 via Bluetooth 21, 31, and obtains all items (data) of the fusion history assigned the same work serial number from the recording unit 23. The construction information generation unit 68 then stores the obtained fusion history in an information table in the memory 35. As a result, the work results such as images in each of the above work steps, the joint information, and the position information, as well as the fusion history, are associated (linked) via the primary key. Then, when the worker taps the "OK" icon, the process completion data request unit 61 determines that the process is complete and sends the joint information and fusion history read in the previous process via the Internet 32 to the work recording device 4 along with the above-mentioned primary key, and they are stored in the memory unit 42.

Furthermore, in this embodiment, the process completion data request unit 63 transmits the job sequence number and all items of the fusion history together with the above-mentioned primary key via the Internet 32 to the work recording device 4, where they are stored in the memory unit 42. The fusion status analysis unit 73 then analyzes all items (data) of the fusion history that have been transmitted. This makes it easier to understand and confirm error history, fusion trends, and the condition of the fusion machine, and can serve as evidence for preventing fusion abnormalities and improving fusion quality.

14) Work confirmation process (K15)
Finally, the work instruction output unit 61 outputs the items entered in the above process to the touch panel 36 of the smartphone 3. After confirmation, when the worker taps the "OK" icon, the process completion data request unit 61 determines that the process is complete and stores data indicating that confirmation has been completed in an information table in the memory 35. In addition, the data indicating that confirmation has been completed is transmitted to the work recording device 4 together with the above primary key via the Internet 32 and stored in the storage unit 42. This completes the installation work of the joint.

In this way, the memory unit 42 records, for each fusion task, various captured images as process completion data acquired during the above series of processes, read joint information, measured location information, and electrofusion information (fusion history). The construction information output unit 71 then outputs various forms and mappings for each fusion task based on the construction information generated by associating (linking) it with the above primary keys.

In the above work process, as shown in FIG. 9, the resin pipe construction information is generated through the following steps: a primary key issuance step S1, which issues a unique primary key for each fusion operation for one or more of the multiple fusion operation steps; a work instruction output step S2, which outputs the work details for that operation to the mobile device in the form of illustrations and/or text; a process completion data request step S3, which requests process completion data indicating the end of the operation; a joint information request step S4, which requests the reading of joint information for the fitting body; an electrofusion instruction step S5, which sends the read joint information to the electrofusion device and activates the electrofusion device to begin fusion of the fitting body; an electrofusion information request step S6, which requests electrofusion information related to the fusion from the electrofusion device after fusion is completed; a position information request step S7, which requests position information for the fitting body whose fusion is complete; and a construction information generation step S8, which generates construction information by associating the acquired process completion data, the read joint information, the acquired electrofusion information, and the acquired position information based on the primary key.

The work instruction output step S2 and the process completion data request step S3 include at least the above-mentioned work steps K1-6 and K11, the joint information request step S4 corresponds to the above-mentioned work step K9, the electrofusion instruction step S5 corresponds to the above-mentioned work step K10, the electrofusion information request step S6 includes the above-mentioned work steps K10 and K14, the position information request step S7 corresponds to the above-mentioned work step K13, and the construction information generation step S8 includes the above-mentioned work step K15. Because each piece of data is associated (linked) by a primary key issued for each fusion operation, construction information can be generated that links a series of work steps (history) for each fusion operation of the joint body simply by progressing through the above-mentioned work steps according to the output of the work instruction output unit 61. Furthermore, because each piece of data is associated (linked) by a primary key issued for each fusion operation, construction information can be output in various formats for each fusion operation without being confused with other fusion operation data. Therefore, for each fusion operation (each joint), it is possible to output (display) the fusion history, a list of images taken during each operation, and location information individually or collectively.

In addition, this embodiment further includes a previous process completion confirmation step S4' before the joint information request step S4, which confirms whether the previous steps have been completed normally. Furthermore, the electrofusion information request step S6 includes a fusion status analysis step that analyzes the fusion status based on the electrofusion information (some items of the fusion history data). The previous process completion confirmation step S4' makes it possible to detect and prevent work defects that could cause poor construction (work) before fusion begins. Furthermore, the fusion status analysis step alerts the worker to suspected fusion abnormalities immediately after fusion, allowing them to reconfirm and review the work. Thus, by including these steps, construction quality can be further improved, even if the worker simply follows the display (output) on the mobile device 3 to proceed with a series of fusion work.

Then, for example, as shown in FIG. 10(a), the mapping unit 71a maps the construction location on a map based on the location information of the generated construction information. Furthermore, as shown in FIG. 10(b), the report output unit 71b outputs a checklist as a report based on the generated construction information. Furthermore, as shown in FIG. 10(c), the fusion history can also be output as a list. Furthermore, the captured image output unit 71c outputs the captured images in list format or table format based on the shooting date and time information and/or shooting location information assigned to the captured images. This output information can be accessed and used from the user terminal 9 via the server that serves as the work recording device 4 by not only the contractor, but also those with access rights such as the contractor and related contractors. Note that these output examples are merely examples, and the output format can be changed and adjusted as appropriate.

In addition, because the completion of all of the above work processes is confirmed, by listing (outputting) the work completion data for each process, it is possible to determine whether the entire fusion work was carried out correctly. The above various judgments can be made not only after the work has been completed, but also in real time.

Next, other possible embodiments of the present invention will be described, in which the same components as those in the above-described embodiment are designated by the same reference numerals.
In the above embodiment, in the previous process completion confirmation step (K8), the quality determination unit 72 determines the quality of the work by comparing the photographed images and information stored (saved) in the previous work steps with the normal state via the previous process completion confirmation unit 63c. However, in addition to this, in the fusion completion step (K11), it is also possible to determine the quality of the fusion based on an indicator image that shows the degree of protrusion of the indicator 107.

In this case, the pass/fail judgment unit 72 stores the judgment result in the memory unit 42 and transmits it to the process completion data request unit 63. If the judgment result is NG, the process completion data request unit 63, for example, displays the judgment result on the touch panel 36 of the smartphone 3 and also displays a back button to return to the initial work process, thereby urging the worker to start the work over again. On the other hand, if the judgment result is OK, the process completion data request unit 63 determines that the process is complete, and the construction information generation unit 68 stores the judgment result in an information table in the memory, etc. 35. In this way, the need for fusion is judged from the photographed image of the indicator, and the process completion is determined, thereby further improving the construction quality.
In the above embodiment, the data inputted into the mobile terminal 3 is transmitted to the work recording device 4 via the second communication means 32 (Internet). However, by providing the electrofusion device 2 with the second communication means 32 (Internet), the data may be transmitted to the work recording device 4 via the electrofusion device 2.

In addition, in the above embodiment, the construction information output unit 71 is provided in the work recording device 4, but it can also be provided in the mobile terminal 3. This allows construction information to be output on the mobile terminal 3, and the output construction information (data) to be transmitted to the work recording device 4.

In the above embodiment, location information measured by the GNSS receiver 5 is used, but the GNSS receiver 5 may be omitted and location information obtained by a location information acquisition means (GPS) built into the mobile terminal 3 may be used.

In addition, in the above embodiment, completion data and captured images were sent to the work recording device 4 after the work process was completed, but depending on the communication situation, the data may be saved on the mobile device 3 and sent to the work recording device 4 later. Each piece of data is associated (linked) by a primary key issued for each fusion work, so there is no chance of confusion with other fusion work data.

The present invention can be used particularly as a construction information generation system for construction information on polyethylene pipes (PE pipes) used in water piping. It can also be used as a management system for this construction information.
