DETAILED DESCRIPTION OF THE INVENTION

[0009] First Embodiment [Configuration of construction management system] A construction management system according to a first embodiment will now be described. The construction management system according to this embodiment is a system that uses BIM (Building Information Modeling) to manage the construction of electrofusion joints at a construction site where a building is being constructed. "Construction" here refers to the process of fusing a joint and a pipe by passing electricity through the joint using a fusion device 100. An electrofusion joint is a joint that enables pipes made of a thermoplastic material such as polyethylene to be connected by electrofusion. In the following description, an electrofusion joint will be simply referred to as a joint. BIM (an example of a drawing) is a technology for creating a three-dimensional model of a building structure. In the construction management system of this embodiment, data (construction model data) of the building to be constructed, which is three-dimensionally modeled using BIM, is used for construction management. The construction model data of this embodiment also includes piping structures corresponding to water supply, sewerage, etc., and the presence of joints that connect pipes (for example, straight pipes) in the piping structure is also indicated.

[0010] 1 shows an example of a construction management system according to this embodiment. The construction management system shown in the figure includes a fusion splicer 100, construction terminals 200 (200A, 200B), a construction management server 300, and positioning-enabled communication devices 500 (500-1, 500-2, 500-3).

[0011] The construction site 1 is provided with a fusion device 100 and a construction terminal 200A used by a worker who will construct the joint. A construction work support application that supports the worker in constructing the joint at the construction site 1 is installed in the construction terminal 200A.

[0012] The fusion device 100 is a device that applies electricity to a joint to join two pipes together with the joint. To construct the joint, an operator inserts a pipe into the joint and then applies electricity to the joint using the fusion device 100. The application of electricity heats the heating wire in the joint, and the heat from the heating wire melts and joins the joint and the pipe.

[0013] The fusion device 100 and the construction management server 300 can communicate with each other via a network.

[0014] The fusion device 100 and the processing terminal 200A may be connected so as to be able to communicate with each other. The connection between the fusion device 100 and the processing terminal 200A may be by short-range wireless communication such as Bluetooth (registered trademark). The connection between the fusion device 100 and the processing terminal 200A may also be by a wired data interface such as USB. When fusion apparatus 100 and construction terminal 200A are connected in this manner, communication between fusion apparatus 100 and construction management server 300 may be performed via construction terminal 200A.

[0015] The construction terminal 200A is capable of displaying construction drawings based on the construction model data. The construction terminal 200A is connected to the construction management server 300 via a network so as to be able to communicate with each other.

[0016] The construction management server 300 is a server that performs construction management of joints at the construction site 1.

[0017] The construction terminal 200B is a terminal used by the manager of the construction site 1. The construction terminal 200B is communicably connected to the construction management server 300 via a network. A construction status management application that supports management of the construction status of joints at the construction site 1 by the manager is installed in the construction terminal 200B.

[0018] The positioning-compatible communication devices 500 (500-1, 500-2, 500-3) are provided at predetermined positions in the construction site 1. In the figure, three positioning-compatible communication devices 500-1, 500-2, 500-3 are shown, but the positioning-compatible communication devices 500 may be provided in the required number at the required locations depending on the size of the construction site 1, the shape of the space, etc., after satisfying the number required for positioning. Specifically, the positioning-enabled communication device 500 of this embodiment may be a wireless LAN access point (one example of a communication system). Alternatively, the positioning-enabled communication device 500 may be a beacon transmitter, a UWB (Ultra Wide Band) signal transmitter, or the like. The following description will be given taking as an example a case where the positioning-enabled communication device 500 is a wireless LAN access point. The positioning-enabled communication device 500 communicates with a communication device 110 provided in the fusion device 100.

[0019] [Example of fusion device configuration] 2 shows an example of the configuration of a fusion splicing apparatus 100. The fusion splicing apparatus 100 shown in the figure includes a communication unit 101, a display unit 102, an operation unit 103, a code reader 104, a connector 105, a control unit 106, a storage unit 107, and a communication device 110. The functions of the fusion splicing apparatus 100 shown in the figure are realized by a CPU (Central Processing Unit) included in the fusion splicing apparatus 100 executing a program.

[0020] The communication unit 101 communicates with the construction terminal 200A by, for example, short-range wireless communication. The communication unit 101 may also be capable of communicating with the construction management server 300 by being compatible with network communication.

[0021] The display unit 102 displays an image under the control of the control unit 106 .

[0022] The operation unit 103 is a part that receives operations from an operator who is a user. The operation unit 103 of the fusion device 100 may include a touch panel combined with the display unit 102.

[0023] The code reader 104 is a component that reads barcodes. The code reader 104 may be capable of reading codes other than barcodes, such as two-dimensional codes.

[0024] The connectors 105, 105 are portions for passing electricity through the heating wires of the joints, and are provided so as to be drawn out from the main body of the fusion device 100 via cables. The connectors 105 are attached to predetermined locations on the joint so that they can be connected to the heating wires of the joints. In this state, when electricity is passed through the connectors 105 under the control of the control unit 106, current is also supplied to the heating wires of the joints, fusing the joints and the pipes together to physically connect them.

[0025] The control unit 106 performs various controls in the fusion device 100. The control unit 106 includes a construction history information processing unit 161, a position information acquisition unit 162, and an energization control unit 163.

[0026] The construction history information processing unit 161 generates construction history information. The construction history information is information relating to the construction history of each joint. The construction history information processing unit 161 generates the construction history information for the joint to be constructed each time the fusion device 100 applies current in accordance with the construction of the joint to be constructed. Furthermore, the construction history information processing unit 161 (an example of a construction history information processing unit) of this embodiment associates the construction history information generated by the construction history information processing unit 161 with the position information acquired by the position information acquisition unit 162.

[0027] The position information acquisition unit 162 acquires position information indicating the position where the joint to be constructed is constructed at the construction site 1. Such position information of the joint to be constructed is joint-specific information that is specific to each joint at the construction site 1. The current control unit 163 executes control (current control) for passing a current through the connectors 105, 105.

[0028] The storage unit 107 stores information related to the fusion device 100. The storage unit 107 includes a construction history information storage unit 171. The construction history information storage unit 171 stores construction history information. The construction history information is information related to the construction results of each joint constructed (fused to a pipe) by the fusion device 100 at the construction site 1.

[0029] The communication device 110 communicates with each of the positioning-enabled communication devices 500. In this embodiment, the communication device 110 receives AP (access point) location information transmitted from the positioning-enabled communication devices 500 as access points of a wireless LAN, and measures the radio wave intensity of each of the positioning-enabled communication devices 500 of the communication partners. In this case, the communication device 110 is configured to receive power supply from one of the connectors 105, 105. In other words, one of the connectors 105 is capable of branching the power supplied for energization and supplying it to the communication device 110. When the communication device 110 receives power supply from the connector 105, it starts up and can perform communication. The communication device 110 may be fixedly attached to, for example, the connector 105 that supplies power. Furthermore, power may be supplied from the connector 105 to the communication device 110 via a wire or by contactless power transmission. The communication device 110 is communicably connected to the fusion device 100. The connection between the communication device 110 and the fusion device 100 may be via a data interface such as a USB (Universal Serial Bus) or may be via short-range wireless communication such as Bluetooth (registered trademark).

[0030] [About construction history information] 3(A) shows an example of construction history information stored in the construction history information storage unit 171 corresponding to one joint. As shown in the figure, the construction history information corresponding to one joint has a construction basic information field FL1, a construction joint information field FL2, a fusion result information field FL3, and a joint-specific information field FL4.

[0031] The construction basic information field FL1 is a field for storing basic information in the construction history information. 3(B) shows a specific example of the construction basic information field FL1. As a specific example, the contents of the construction basic information field FL1 for five joints that have been constructed are shown in the figure. The construction basic information field FL1 in the figure includes fields for the fusion device ID, construction number, and construction date and time.

[0032] The field of the fusion device ID stores the fusion device ID indicating the fusion device 100 that has applied current according to the corresponding work (fusion). The construction number field stores the number (construction number) assigned to the construction of the corresponding joint. The construction date and time field stores the date and time when the corresponding joint was constructed (construction date and time).

[0033] The construction joint information field FL2 stores information (construction joint information) about the corresponding construction target joint. Figure 3(C) shows a specific example of the construction joint information field FL2. This figure shows the construction joint information field FL2 corresponding to the same five joints as in Figure 3(B). The construction joint information field FL2 in this figure includes fields for type, size, manufacturer, control number, standard resistance, standard output voltage, standard current flow time, and barcode data.

[0034] The product type field stores information indicating the product type (classification) of the corresponding joint to be constructed, and the size field stores information indicating the size of the corresponding joint to be constructed. The manufacturer field stores information indicating the manufacturer of the corresponding joint to be constructed. The control number field stores the control number (product number) assigned to the corresponding joint to be constructed. The standard resistance field stores information indicating the standard resistance value of the heating wire of the corresponding joint to be constructed. The standard output voltage field stores information indicating the standard output voltage to be applied when energizing the corresponding joint to be constructed. The standard energization time field stores information indicating the standard time for energizing the corresponding joint to be constructed. The barcode data field stores the value (barcode data) of the specification barcode affixed to the corresponding fitting to be installed. The specification barcode affixed to the fitting is a coded version of the fitting specification information that indicates the specifications of the corresponding fitting. The fitting specification information in the specification barcode indicates the corresponding fitting type, size, serial number, SDR value (coefficient of outer wall thickness), characteristics of the heating wire material (type, resistance change tolerance, etc.), and energization voltage. It also indicates the standard resistance value of the heating wire, resistance tolerance of the heating wire, temperature characteristics of the heating wire, energization time, temperature correction coefficient, check digit (C / D), etc. The joint specification information read from such a specification barcode is reflected in the information in the construction joint information field FL2.

[0035] The fusion result information field FL3 stores information indicating the results of construction of the corresponding joint. Figure 4(A) shows a specific example of the fusion result information field FL3. This figure shows the fusion result information field FL3 corresponding to the same five joints as in Figures 3(B) and 3(C). The fusion result information field FL3 in this figure includes fields for the end state, ambient temperature, actual resistance, minimum output voltage, maximum output voltage, minimum output current, maximum output current, minimum input voltage, maximum input voltage, target current flow time, actual current flow time, remaining current flow time, and fusion energy.

[0036] The end status field stores an end code that indicates the state (end status) of the corresponding joint after construction. The end code has a predetermined value that corresponds to the end status, such as normal completion, power outage, or current abnormality. The end status is information that indicates the construction quality of the joint. The field of the environmental temperature stores information indicating the ambient temperature (environmental temperature) measured by the fusion device 100 when the corresponding joint is being worked. The field of actual resistance stores information indicating the actual resistance value (actual resistance) of the heating wire of the corresponding joint measured by the fusion device 100 during construction. The field of the minimum output voltage stores information indicating the minimum value of the output voltage measured when the fusion device 100 is energized during the application. The maximum output voltage field stores information indicating the maximum value of the output voltage measured when the fusion device 100 is energized during the application. The field of the minimum output current stores information indicating the minimum value of the output current measured when the fusion device 100 is energized during the application. The maximum output current field stores information indicating the maximum value of the output current measured when the fusion device 100 is energized during the process. The field of the minimum input voltage stores information indicating the minimum value of the input voltage measured when the fusion device 100 is energized during the application. The maximum input voltage field stores information indicating the maximum value of the input voltage measured when the fusion device 100 is energized during the application. The target energization time field stores the target energization time calculated by the fusion device 100 based on predetermined conditions during the application. The field for actual energization time stores the actual energization time during which the fusion device 100 actually energized during the process. The remaining energization time field stores the remaining energization time, which is the shortage of the actual energization time compared to the target energization time when the fusion device 100 actually energizes during the process. The fusion energy field stores information indicating the energy used by the fusion device 100 during application (fusion).

[0037] The joint-specific information field FL4 stores the joint-specific information acquired corresponding to the joint to be constructed. Figure 4(B) shows a specific example of the joint-specific information field FL4. This figure shows the joint-specific information field FL4 corresponding to the same five joints as in Figure 4(A). The joint-specific information field FL4 in Figure 4(B) stores joint position information as joint-specific information. Specifically, the joint position information in Figure 4(B) is an example that includes fields for latitude, longitude, and floor number. In this way, the joint position information indicates the horizontal position using latitude and longitude, and the vertical position using floor number. In other words, the joint position information can indicate the position of the joint in the three-dimensional space of the construction site 1.

[0038] [Example of construction terminal configuration] 5 shows an example of the configuration of the construction terminal 200. The construction terminal 200 in the figure includes a communication unit 201, a display unit 202, an operation unit 203, a camera 204, a control unit 205, and a storage unit 206.

[0039] The communication unit 201 communicates with the fusion device 100 by short-range wireless communication. The communication unit 201 also communicates with the construction management server 300 via a network.

[0040] The display unit 202 displays an image under the control of the control unit 205 .

[0041] The operation unit 203 is a part that receives operations from a worker who is a user. The construction terminal 200 may include a touch panel combined with the display unit 202 in the operation unit 203.

[0042] The camera 204 captures an image to obtain a captured image.

[0043] The control unit 205 executes control in the construction terminal 200. The control unit 205 includes a construction work support processing unit 251 and a construction status management unit 252.

[0044] The construction work support processing unit 251 executes processing according to the function of the construction work support application installed in the construction terminal 200 A. As a specific example, the construction work support processing unit 251 can display a drawing of the construction site 1 corresponding to piping construction on the display unit 202 based on the construction model data stored in the construction model data storage unit 261.

[0045] The construction status management unit 252 executes processing according to the function of the construction status management application installed in the construction terminal 200 B. As a specific example, the construction status management unit 252 can display information on the progress status of the construction of joints at the construction site 1 on the display unit 202 based on the construction model data stored in the construction model data storage unit 261.

[0046] The storage unit 206 stores information related to the construction terminal 200. The storage unit 206 includes a construction model data storage unit 261. The construction model data storage unit 261 stores construction model data acquired from the construction management server 300. The construction model data stored in the construction model data storage unit 261 is used when a worker installs a joint.

[0047] [Configuration example of construction management server] 6 shows an example of the configuration of the construction management server 300. The functions of the construction management server 300 shown in the figure are realized by a CPU provided in the construction management server 300 executing a program. The construction management server 300 in the figure includes a communication unit 301, a control unit 302, and a storage unit 303.

[0048] The communication unit 301 communicates with the construction terminals 200A, 200B, etc. via a network. The communication unit 301 may also be capable of communicating with the fusion apparatus 100 via a network.

[0049] The control unit 302 executes control in the construction management server 300. The control unit 302 includes a construction model data processing unit 321. The construction model data processing unit 321 executes processing related to the construction model data stored in the construction model data storage unit 331 .

[0050] The storage unit 303 stores information related to the construction management server 300. The storage unit 303 includes a construction model data storage unit 331. The construction model data storage unit 331 stores the construction model data. The construction model data stored in the construction model data storage unit 331 is data structurally linked (associated) with the construction history information corresponding to the joints present in the construction model data.

[0051] [Example of processing procedure for construction model data processing] An example of a processing procedure executed by the fusion apparatus 100 and the construction management server 300 of this embodiment will be described with reference to the flowchart in Fig. 7. The processing procedure in Fig. 7 corresponds to a process performed when connecting pipes in accordance with the construction of one joint performed by an operator using the fusion apparatus 100.

[0052] First, an example of a processing procedure executed by the fusion device 100 will be described. Step S101: When performing construction work to fuse one joint to a pipe, the worker first attaches the connectors 105, 105 of the fusion device 100 to the joint to be constructed. Next, the worker operates the code reader 104 of the fusion device 100 to read the specification barcode attached to the joint to be used in the construction (the joint to be constructed). In the control unit 106 of the fusion device 100, the construction history information processing unit 161 acquires joint specification information from the specification barcode read by the code reader 104.

[0053] Step S102: In the control unit 106 of the fusion apparatus 100, the energization control unit 163 sets energization parameters corresponding to the joint to be worked, based on the joint specification information acquired by reading the specification barcode in step S101.

[0054] Step S103: The operator performs an operation to start energization. In response to the operation to start energization, the energization control unit 163 starts energization of the connectors 105, 105 as energization control.

[0055] Step S104: Step S104 is a process of the communication device 110 connected to the connector 105. The connector 105 is capable of branching and outputting the power received by energization to the communication device 110. Therefore, when energization to the connector 105 is started in step S103, power supply to the communication device 110 is also started. Upon receiving the power supply, the communication device 110 starts up and communicates with positioning-capable communication devices 500 that are within communication distance and serve as wireless LAN access points. In this embodiment, the number of positioning-capable communication devices 500 that the communication device 110 needs to communicate with for positioning is three, since three-point positioning is performed. In this case, if there are four or more positioning-capable communication devices 500 with which the communication device 110 can communicate, the communication device 110 may communicate with the three positioning-capable communication devices 500 in descending order of radio wave strength, for example.

[0056] By performing communication in step S104, the communication device 110 receives communication device location information indicating the location of each communication partner's positioning-compatible communication device 500. The communication device location information indicates the location where the corresponding positioning-compatible communication device 500 is installed by latitude, longitude, and height. The height indicates the number of floors in the building serving as the construction site 1, but may also indicate, for example, altitude. Furthermore, the communication device 110 measures the radio wave intensity of each positioning capable communication device 500 of the communication partner. The communication device 110 measures its own position using the communication device position information and radio wave intensity information for each communication partner positioning-enabled communication device 500. The communication device 110 outputs the communication device position information indicating its measured position to the fusion apparatus 100.

[0057] Step S105: In the fusion apparatus 100, the position information acquisition unit 162 acquires the communication device position information output from the communication device 110 in step S104 as splice position information. The joint position information is position information that indicates the position where the joint to be constructed this time was constructed at the construction site 1. The communication device position information indicates the position of the communication device 110 attached to the connector 105 that is in contact with the joint to be constructed and conducting electricity, and therefore can be considered to correspond to the position where the joint to be constructed was constructed.

[0058] Step S106: In the fusion apparatus 100, the current control unit 163 stops current application when the required current application time has elapsed since the current application was started in step S103.

[0059] Step S107: When the energization is terminated in step S106, the construction history information processing unit 161 generates construction history information that reflects the current construction result. Furthermore, since the power supply is no longer performed in response to the termination of the energization, the communication device 110 also stops operating. The construction history information has the structure shown in Fig. 3(A). When generating the construction history information, the construction history information processing unit 161 stores the joint position information acquired in step S105 as joint-specific information in the joint-specific information field FL4. In this way, the process by the construction history information processing unit 161 (construction history information processing unit) to store the joint position information as joint-specific information in the joint-specific information field FL4 corresponds to the process of associating the joint position information with the construction history information.

[0060] Step S108: The construction history information processing unit 161 stores the construction history information generated in step S107 in the construction history information storage unit 171. In addition, the construction history information processing unit 161 transmits the construction history information generated in step S106 to the construction management server 300.

[0061] Next, an example of the processing procedure of the construction management server 300 will be described. Step S201: In the construction management server 300, the construction model data processing unit 321 receives the construction history information transmitted by the fusion device 100 in step S107.

[0062] Step S202: The construction model data processing unit 321 compares the position indicated by the joint position information as joint-specific information contained in the construction history information received in step S201 with the position of the joint within the model in the construction model data stored in the construction model data memory unit 331 (an example of a construction position).

[0063] Step S203: The construction model data processing unit 321 determines whether there is a joint in the model that matches the position indicated by the joint position information as a result of the comparison in step S202. At this time, the construction model data processing unit 321 may determine that the positions match if, for example, the number of floors is the same and the difference in position specified by latitude and longitude is within a certain range between the position indicated by the joint position information and the position of the joint in the model. If it is determined in step S203 that there is a joint within the model that matches the position indicated by the joint position information, the construction model data processing unit 321 will have identified the joint within the model that is determined to match as corresponding to the joint to be constructed this time.

[0064] Step S204: If it is determined in step S203 that there is no joint in the model that matches the position indicated by the joint position information, there is a possibility that, for example, the error in the joint position measured by the fusion device 100 was large. Therefore, in this case, the construction model data processing unit 321 selects, as candidates, intra-model joints located within a certain distance range based on the position indicated by the joint position information in the construction model data. The construction model data processing unit 321 collates predetermined specification items (for example, type, diameter, etc.) of each candidate intra-model joint with the same predetermined specification items of the joint to be constructed. In the construction model data, the specification items of the joints in the model are associated with joint specification information for each joint in the model. In addition, the specification items of the joints to be constructed are included in the received construction history information.

[0065] Step S205: The construction model data processing unit 321 determines whether or not there is any candidate intra-model joint whose specification item content matches that of the joint to be constructed as a result of the collation in step S204.

[0066] Step S206: If it is determined in step S205 that there is no model joint whose specification item contents match the joint to be constructed, it can be said that, for example, the accuracy of the joint position measured by the fusion device 100 is not reliable. Therefore, in this case, the construction model data processing unit 321 compares the construction schedule for each candidate joint shown in the construction model data with the construction date and time of the joint to be constructed. In other words, the construction model data processing unit 321 in this case attempts to identify, as the intra-model joint corresponding to the joint to be constructed, the intra-model joint that is shown to be constructed on the date and time corresponding to the construction date and time of the joint to be constructed in the already planned construction schedule. The construction schedule for each joint in the model is shown in the construction model data. The construction date and time of the joint to be constructed is included in the received construction history information.

[0067] Step S207: Based on the result of the comparison in step S206, the construction model data processing unit 321 determines the model internal joints that are indicated in the construction schedule to be constructed on a date and time corresponding to the construction date and time of the joint to be constructed as the model internal joints to be connected.

[0068] Step S208: If it is determined in step S203 that there is a joint within the model that matches the position indicated by the joint position information, or if it is determined in step S205 that there is a joint within the model whose specification item contents match the joint to be constructed, or after processing in step S207, the construction model data processing unit 321 (an example of an identification information processing unit) updates the construction model data stored in the construction model data memory unit 331. As part of the processing of step S208, if it is determined in step S203 that there is a joint within the model that matches the position indicated by the joint position information, the construction model data is updated by linking the construction history information received in step S201 to the joint within the model that matches the position indicated by the joint position information. As part of the processing of step S208, if it is determined in step S205 that there is a model joint whose specification item contents match those of the joint to be constructed, the construction model data is updated by linking the construction history information to the model joint whose specification item contents match those of the joint to be constructed. In the process of step S208, if the process of step S207 has been carried out, the construction model data is updated by linking the construction history information to the joints within the model determined as the connection targets in step S207.

[0069] In the construction model data, a joint ID (an example of joint identification information) is assigned to each joint in the model so that it is unique. The linking of construction history information to joints in the model in step S208 can be understood as a process of associating the joint ID of a joint in the model whose construction position in the construction model data corresponds to the actual joint that was the target of construction this time at the construction site 1. In other words, the construction model data of this embodiment makes it possible to manage joints in the model that exist in the construction model data of the construction site 1 and actual joints to be constructed at the construction site 1 in correspondence with their construction positions.

[0070] [Example of processing procedure for construction status display] In this embodiment, the construction terminal 200 used by the manager can output information on the construction status at the construction site 1 on the display based on the construction model data stored in the construction management server 300.

[0071] An example of a processing procedure executed by the construction terminal 200B in relation to the display of information relating to the construction status will be described with reference to the flowchart of Fig. 8. The processing in the figure may be realized by the operation of a construction status management application on the construction terminal 200B.

[0072] Step S301: When the manager wants to grasp the construction status of the joint at the construction site 1, he performs an operation to instruct the construction terminal 200B to display a construction status screen. In response to this operation, the construction status information output unit 253 in the construction terminal 200B acquires construction model data from the construction model data storage unit 331.

[0073] Step S302: The construction status information output unit 253 calculates the progress rate (construction progress rate: an example of progress status) of the construction of the joint at the construction site 1 using the construction model data acquired in step S301. The construction status information output unit 253 can calculate the construction progress rate based on the number of in-model joints with linked construction history information and the number of in-model joints with no linked construction history information among the in-model joints present in the construction model data. In-model joints with linked construction history information indicate joints that have been constructed at the construction site 1, and in-model joints with no linked construction history information indicate joints that have not been constructed at the construction site 1. The construction progress rate may also be calculated as a rate corresponding to joints whose construction has been completed across the entire construction site 1. Alternatively, the construction progress rate may also be calculated as a rate corresponding to joints whose construction has been completed against a construction plan for a predetermined period of time. Alternatively, the construction progress rate may also be calculated as a rate corresponding to joints whose construction has been completed against a construction plan for a specific floor or a specific construction section. The construction status information output unit 253 may also calculate each of these construction progress rates.

[0074] Step S303: The construction status information output unit 253 determines whether or not there is a construction defect. To this end, the construction status information output unit 253 determines whether or not there is construction history information whose end state does not indicate normal completion among the construction history information linked to the intra-model joint in the construction model data acquired in step S301.

[0075] Step S304: If it is determined in step S303 that there is a defective construction area, the construction status information output unit 253 causes the display unit 202 to display a construction status screen including a notification of the defective construction and the construction progress rate calculated in step S302. The notification of construction defects on the construction status screen may, for example, indicate the position of the joint where the construction defect occurred on a drawing of the construction site 1 displayed using the construction model data. By displaying such a notification of construction defects, the manager can accurately grasp the location where the construction defect occurred at the construction site 1 and can quickly take measures such as re-construction. Furthermore, the construction progress rate on the construction status screen may be displayed simultaneously or selectively for the entire construction site 1, for a predetermined period, and for a predetermined construction section.

[0076] Step S305: If it is determined in step S304 that there are no construction defects, the construction status information output unit 253 causes the display unit 202 to display a construction status screen that includes the construction progress rate calculated in step S302 and does not include a notification of construction defects.

[0077] Second Embodiment Next, a second embodiment will be described. Fig. 9 shows an example of the configuration of a construction management system corresponding to the second embodiment. In Fig. 9, the same parts as in Fig. 1 are given the same reference numerals and the description thereof will be omitted as appropriate. In the construction management system of this embodiment, a positioning capable communication device 500A is provided in place of the positioning capable communication device 500 of the first embodiment. The positioning-enabled communication device 500 in the first embodiment is a wireless LAN access point, a beacon transmitter, or a UWB signal transmitter. In contrast, the positioning-enabled communication device 500A in this embodiment may be, for example, a transmitter (IMES transmitter) compatible with IMES (Indoor Messaging System). The positioning-enabled communication device 500A measures the position of a terminal located within its communication range and transmits position information indicating the measured position to the terminal. The position information transmitted by the positioning-enabled communication device 500A may indicate the position using, for example, latitude, longitude, and height (e.g., floor number or altitude). The positioning-enabled communication device 500A may be placed so as to cover the location at the construction site 1 where the joints are to be constructed as its communication range.

[0078] The configurations of the fusion splicing apparatus 100 and construction management server 300 in this embodiment may be similar to those shown in FIGS.

[0079] In this embodiment, the communication device 110, which is activated by the power supply control of the fusion apparatus 100, receives the position information transmitted from the positioning-enabled communication device 500A. As the process of step S105 in Fig. 7, the position information acquisition unit 162 of the fusion apparatus 100 acquires the position information received by the communication device 110 as joint position information (joint-specific information).

[0080] Third Embodiment Next, a third embodiment will be described. Fig. 10 shows an example of the configuration of a management system corresponding to the third embodiment. In Fig. 10, the same parts as in Fig. 1 are given the same reference numerals and the description thereof will be omitted as appropriate.

[0081] 10, a positioning-enabled communication device 500B is provided when the fusion apparatus 100 acquires joint position information as joint-specific information. The positioning-enabled communication device 500B of this embodiment may be, for example, a locator compatible with the Quuppa Intelligent Locating System (registered trademark, hereinafter referred to as the "Quuppa system"). The positioning-enabled communication device 500B may be appropriately placed so that the communication range covers the location at the construction site 1 where the joints are to be constructed.

[0082] The fusion apparatus 100 in this embodiment may have the same configuration as that shown in Fig. 2. In addition, the communication device 110 in this embodiment is configured to transmit a positioning signal corresponding to the Quuppa system upon activation. The positioning signal transmitted by the communication device 110 includes, for example, a fusion apparatus ID that uniquely identifies the corresponding fusion apparatus 100. In this embodiment, the communication device 110 is activated when the fusion device 100 energizes the connector 105, and the activated communication device 110 transmits a signal.

[0083] The positioning-enabled communication device 500B, which serves as a locator in the Quuppa system, calculates the angle of incidence of the radio waves output when the communication device 110 transmits a positioning signal, and transmits a position calculation request to the position calculation server 600, which includes its own position, the calculated angle of incidence, and the received fusion device ID. The position calculation server 600 calculates the position of the object to be positioned using information such as the position of the positioning-compatible communication device 500B and the angle of incidence included in the received position calculation request. The position of the object to be positioned calculated in this manner indicates the position of the communication device 110. In other words, the calculated position of the object to be positioned indicates the position where the splice of the splice target was spliced. The position calculation server 600 transmits a position information notification to the construction management server 300, which includes position information indicating the calculated position and a fusion device ID. The construction management server 300 transmits the transmitted position information notification to the corresponding fusion device 100. The fusion device 100 acquires the position information included in the splice position notification transmitted from the construction management server 300 as splice position information.

[0084] An example of a processing procedure executed by the fusion apparatus 100 and construction management server 300 of this embodiment will be described with reference to the flowchart in Fig. 11. The processing procedure in Fig. 11 corresponds to a process performed when connecting pipes in response to the construction of one joint performed by a worker using the fusion apparatus 100. In this embodiment, the configurations of the fusion apparatus 100 and the construction management server 300 may be the same as those in Figs. 2 and 6.

[0085] First, a description will be given of an example of a processing procedure executed by the fusion apparatus 100. The processing in steps S301 to S303 is the same as steps S101 to S103 in FIG.

[0086] Step S304: The Quuppa system-compatible communication device 110 starts up in response to the start of energization of the connector 105 in step S303, and transmits a positioning signal. In response to the communication device 110 transmitting the positioning signal, the positioning-compatible communication device 500B, which serves as a locator of the Quuppa system as described above, calculates the incident angle of the radio wave, and transmits a position calculation request including its own position, the calculated incident angle, and the received fusion device ID to the position calculation server 600.

[0087] Step S305: In response to the communication device 110 transmitting the positioning signal in step S304, the construction management server 300 transfers the position information notification transmitted from the position calculation server 600 to the fusion apparatus 100 as described above. In the fusion apparatus 100, the position information acquisition unit 162 receives the transferred position information notification, and acquires the position information included in the received position information notification as splice position information.

[0088] The processing of steps S306 to S308 is the same as steps S106 to S108 in Fig. 7. In this case, when generating the construction history information in step S307, the construction history information processing unit 161 stores the position information acquired from the position information notification received in step S305 as joint-specific information in the joint-specific information field FL4.

[0089] Next, an example of a processing procedure executed by the construction management server 300 will be described. Step S401: In response to the communication device 110 transmitting the positioning signal in step S304, as described above, the positioning-compatible communication device 500B transmits a position calculation request to the position calculation server 600. In response to receiving the position calculation request, the position calculation server 600 calculates the position of the object to be positioned, and transmits a position information notification to the construction management server 300. In the construction management server 300, the control unit 302 receives the location information notification transmitted from the construction management server 300 in step S401. Step S402: The control unit 302 transfers the received location information notification to the fusion device 100 indicated by the fusion device ID included in the received location information notification, with the fusion device 100 as the destination (transfer destination).

[0090] Step S403: In response to the construction history information being transmitted from the fusion device 100 in step S307, the construction history information processing unit 161 of the fusion device 100 executes a construction model data update process. The construction model data update process as step S403 is similar to steps S201 to S208 in FIG. 7.

[0091] <Modification> Modifications corresponding to the above-described embodiments will be described below. The following modifications may be combined as appropriate.

[0092] [First Modification] 7, the fusion device 100 transmits the construction history information each time it performs energization control, but construction history information corresponding to each energization control performed during a predetermined construction period may be stored and transmitted collectively at a predetermined timing. In this case, the construction management server 300 may execute the processes of steps S201 to S208 for each piece of transmitted construction history information and link the construction history information to the construction model data.

[0093] [Second Modification] The construction terminal 200 (200A, 200B) of this embodiment may be capable of creating report data showing the construction results of a joint by using the construction model data linked with the construction history information. The construction terminal 200 may be capable of outputting the created report data by displaying, printing, etc. Furthermore, the construction terminal 200 of this embodiment may be capable of linking to the construction model data the results of inspections such as water pressure tests conducted at the construction site 1 on pipes on which joints have been installed, for example. The construction terminal 200 may also be capable of outputting the inspection results linked to the construction model data as a report.

[0094] [Third Modification] In this embodiment, the drawing data that is associated with the positions of the actual joints constructed at the construction site 1 may be drawing data based on a two-dimensional model, rather than construction model data based on a three-dimensional model.

[0095] In addition, a program for implementing the functions of each device in the construction management system may be recorded on a computer-readable recording medium, and the program may be loaded into a computer system and executed to process each device in the construction management system. Here, "loading and executing a program recorded on a recording medium into a computer system" includes installing the program on a computer system. The term "computer system" here includes hardware such as an operating system and peripheral devices. The term "computer system" may also include multiple computer devices connected via a network, including the Internet, a WAN, a LAN, or a dedicated line. The term "computer-readable recording medium" refers to portable media such as floppy disks, optical magnetic disks, ROMs, and CD-ROMs, as well as storage devices such as hard disks built into a computer system. Thus, a recording medium storing a program may be a non-transitory recording medium such as a CD-ROM. The term "recording medium" also includes internal or external recording media accessible from a distribution server for distributing the program. The program code stored on the distribution server's recording medium may be different from the program code executable on a terminal device. In other words, the format in which the program is stored on the distribution server is not important as long as it can be downloaded from the distribution server and installed in a format executable on a terminal device. The program may be divided into multiple parts, each downloaded at a different time and then combined on a terminal device, or each divided program may be distributed by a different distribution server. Furthermore, the term "computer-readable recording medium" also includes a storage medium that stores a program for a certain period of time, such as volatile memory (RAM) within a computer system that serves as a server or client when a program is transmitted over a network. The program may also be a program that realizes part of the above-described functions. Furthermore, the program may be a so-called differential file (differential program) that can realize the above-described functions in combination with a program already stored in the computer system.
