[0021] Work at a construction site may be managed by construction or construction unit (hereafter referred to as "project"). In other words, a project is a unit for managing work at a construction site. Workers or supervisors at a construction site (hereafter referred to as "employees") may participate in a project and be engaged in work managed by the project in which they participate.

[0022] To ensure that work is carried out smoothly, workers may contact other workers participating in the same project. A list of workers participating in each project may be managed using a construction management system. In this case, workers can check the contact information of the person they want to contact in the construction management system. If the construction management system provides a message sending function, workers can contact each other by exchanging messages.

[0023] However, there are cases where calling is more efficient than exchanging messages. To enable calling, it is possible to implement a calling function in the construction management system, but the calling function may consume resources of the construction management system, thereby affecting the operation of the construction management system.

[0024] If the construction management system does not have a calling function, the worker makes a call using a calling application that provides a calling function (for example, a calling application implemented on a device such as a mobile phone or smartphone). In this case, the worker needs to check the contact information in the construction management system, enter the contact information into the calling application, and start the call. The need to check the contact information in the construction management system and enter the contact information in a separate calling application reduces the convenience of communication between workers.

[0025] Some calling applications provide a function that allows group calls for call groups of three or more people. When workers want to communicate with each other through a group call with three or more workers, they need to check the contact information of each worker in the construction management system and add each worker's contact information to the call group. The more people in a call group, the more time it takes to enter contact information in a separate calling application, which reduces the convenience of communication.

[0026] Another possible method is to copy the contact information from the screen for viewing the list of workers for each project managed by the construction management system, and then paste and enter it into the screen for creating a call group in the calling application. In this case, all workers participating in each project are entered into the contact information. However, at construction sites, it is rare to contact all workers participating in a project through a group call, and it is often the case that only a portion of the workers participating in the project are contacted. If all workers participating in a project are entered into the contact information, workers who do not need to be contacted must be deleted from the contact information in order to include only the portion of workers who need to be contacted in the call group, which is time-consuming.

[0027] In any of the above cases, in order to check the contact information of the worker for each project managed by the construction management system and enter the contact information into the call application, the worker needs to start the call application while opening the construction management system screen on the terminal used by the worker. Starting the call application while opening the construction management system screen increases the processing load on the terminal used by the worker.

[0028] In the communication system described in the above-mentioned Patent Document 1 (JP Patent Publication No. 2020-65186), a call group corresponding to the contact information of the workers can be created in advance. Therefore, it is conceivable that the workers will contact each other using the communication system described in Patent Document 1. However, the combination of workers who need to contact at the construction site does not necessarily match the combination of workers associated with the call group created in advance. In addition, when the workers of each project are replaced, the update or creation of the call group is not necessarily performed in a timely manner. In that case, even in the communication system described in Patent Document 1, it may be necessary to create a new call group when contacting, which does not lead to improved convenience of communication between workers.

[0029] In addition, in the communication system described in Patent Document 1, it is also possible to create in advance a call group that covers all combinations of workers who may be contacted. However, even in this case, when workers for each case are replaced, the call group is not necessarily updated or created in a timely manner, and it is difficult to select a call group that includes a combination of people to be contacted from among many call groups, so this does not lead to improved convenience of communication between workers.

[0030] Hereinafter, a construction management system 1 (see FIG. 1) and a terminal device 20 (see FIG. 1), as well as a communication method and a communication program, which can improve the convenience of communication between workers will be described.

[0031] (Overview of Construction Management System 1) As shown in FIG. 1, a construction management system 1 according to an embodiment of the present disclosure includes an information processing device 10, a terminal device 20, and a database 30. The information processing device 10, the terminal device 20, and the database 30 are communicatively connected via a network 80. The information processing device 10, the terminal device 20, and the database 30 may be communicatively connected to each other by a dedicated communication line without via the network 80. The construction management system 1 does not need to include the database 30. The construction management system 1 may include two or more terminal devices 20. The construction management system 1 may include only one terminal device 20.

[0032] The information processing device 10 manages construction work. The information processing device 10 stores and manages information related to construction work management in a database 30 or in the information processing device 10 itself. Information related to construction work management is also referred to as construction management information.

[0033] The terminal device 20 is owned by an employee. An employee who owns and uses the terminal device 20 is also referred to as a user of the terminal device 20. The terminal device 20 executes an application program. The application program includes a construction management application. The construction management application may accept input of construction management information from a user of the terminal device 20. The construction management application may output the construction management information so that the user of the terminal device 20 can recognize the construction management information. The application program includes a calling application. The calling application is used for the user of the terminal device 20 to talk to other employees. The calling application may execute a call between terminal devices 20 included in the construction management system 1. The calling application may execute a call between a terminal device 20 included in the construction management system 1 and an external terminal not included in the construction management system 1.

[0034] In the construction management system 1 according to the present disclosure, the terminal device 20 acquires construction management information from the construction management application before starting a call between workers using the call application. The terminal device 20 assists the user of the terminal device 20 in selecting a call partner based on the construction management information so that the user can easily select a call partner required to start a call. By making it easier to select a call partner, the convenience of communication between workers is improved. The call partner selected when starting a call is also referred to as a call member.

[0035] (Example of the configuration of Construction Management System 1) An example of the configuration of each part of the construction management system 1 will be described below.

[0036] <Information processing device 10> As shown in FIG. 1, the information processing device 10 includes a control unit 11, a storage unit 12, and a communication unit 13.

[0040] The information processing device 10 may be configured to include at least one server. The information processing device 10 may be realized as, for example, a computer such as a notebook PC (Personal Computer) or a tablet PC, or a mobile terminal such as a smartphone. The information processing device 10 is not limited to these examples and may include various devices.

[0041] <Terminal Device 20> The terminal device 20 includes a control unit 21, a storage unit 22, a communication unit 23, an output unit 24, an input unit 25, and an image capture unit 26.

[0049] The terminal device 20 may be realized as, for example, a computer such as a notebook PC or a tablet PC, or a mobile terminal such as a smartphone. The terminal device 20 is not limited to these examples and may include various devices.

[0050] <Database 30> The database 30 may be configured to include at least one server. The database 30 may be configured to include, for example, a semiconductor memory, a magnetic memory, an optical memory, or the like. The database 30 may be configured to include an electromagnetic storage medium such as a magnetic disk. The database 30 may be configured to include a communication module configured to be able to communicate with other devices such as the information processing device 10 or the terminal device 20.

[0051] <Other configuration examples> In the construction management system 1 described above, the information processing device 10, the terminal device 20, or the database 30 may be realized using a cloud service. The information processing device 10, the terminal device 20, or the database 30 may be realized in an on-premise environment. The information processing device 10, the terminal device 20, or the database 30 may be realized in a form in which the cloud service and the on-premise environment are mixed.

[0052] The information processing device 10 may further include an output unit 14. The output unit 14 may be configured in the same manner as or similar to the output unit 24 of the terminal device 20. The information processing device 10 may further include an input unit 15. The input unit 15 may be configured in the same manner as or similar to the input unit 25 of the terminal device 20.

[0053] (Example of operation of Construction Management System 1) Hereinafter, an example of an operation of the terminal device 20 executing a communication method for a user of the terminal device 20 to communicate with other workers in the construction management system 1 will be described. The communication method may be realized as a communication program executed by the control unit 21 of the terminal device 20. The communication program may be stored in a non-transitory computer-readable medium.

[0054] In this operation example, the terminal device 20 is configured to take images of the construction site using the photographing unit 26 and to perform a voice call while sharing the images between multiple terminal devices 20 in a call, that is, to perform a so-called video call. The terminal device 20 may be configured to perform only a voice call without sharing images.

[0055] The control unit 21 of the terminal device 20 receives an input from a user specifying a case (step S1). Step S1 can also be described as a step of specifying a case. The control unit 21 executes a construction management application, and receives an input from the user specifying a case at the input unit 25 as a function of the construction management application. As a function of the construction management application, the control unit 21 causes the output unit 24 to display a case screen 40 that displays information related to the specified case, as exemplified in FIG. 3.

[0056] Returning to Fig. 2, the control unit 21 determines whether or not an operation input for preparing a call has been made (step S2). Specifically, the control unit 21 determines that an operation input for preparing a call has been made when the input unit 25 receives an operation input for a remote call button 41 included in the case screen 40 illustrated in Fig. 3. The interface for receiving the operation input for preparing a call is not limited to the illustrated embodiment and may include various other embodiments.

[0057] If there is no operation input to prepare for a call (step S2: NO), the control unit 21 returns to the case designation procedure of step S1. The control unit 21 may repeat the determination procedure of step S2 until an operation to prepare for a call is input. The control unit 21 may process the operation input in the input unit 25 as an interrupt signal while executing other functions of the construction management application, and when there is any operation input, execute the determination procedure of step S2 to determine whether there is an operation input to prepare for a call.

[0058] Returning to FIG. 2, when an operation input for preparing a call is received (step S2: YES), the control unit 21 launches a call application from the construction management application (step S3). The control unit 21 also acquires an updated list of workers participating in the specified project, and causes the output unit 24 to display information on the workers included in the acquired list (step S4). Step S4 includes a step of acquiring an updated list of workers participating in the specified project. The control unit 21 also accepts an input from the user to select at least one call member (step S5). Step S5 can also be said to be a step of causing the user to select at least one call member.

[0059] When the control unit 21 launches the call application, it causes the output unit 24 to display a call group screen 50 exemplified in FIG. 4. The control unit 21 passes information specifying a case from the construction management application to the call application. That is, when the call application is launched, it obtains information specifying a case from the construction management application. By the call application obtaining information specifying a case from the construction management application, the user does not need to specify a case in the call application. By not requiring the user to specify a case in the call application, the user's operational input is reduced. As a result, user convenience is improved.

[0060] The call group screen 50 includes a display of a call group related to a case specified in the construction management application before the call application is started. When the call application is started, the control unit 21 obtains from the construction management application an updated list of workers participating in the case specified in the construction management application, and transfers the obtained list to the call application. The control unit 21 may obtain the updated list of workers participating in the case specified in the construction management application from the database 30 via the API.

[0061] By the terminal device 20 acquiring the latest list of workers in the call application, the user of the terminal device 20 does not need to check the workers who will participate in the project in the construction management system 1 and input the call members into the call application by the user himself / herself. By not needing to check the workers who will participate in the project in the construction management system 1, the user does not need to keep the construction management application open on the terminal device 20. As a result, the processing load of the terminal device 20 used by the user can be reduced.

[0062] The call group screen 50 includes a display of a case name 51. The case name 51 is the name of the case that was specified in the construction management application before the call application was launched.

[0063] The call group screen 50 includes a call history display 52 related to the specified case. The call history display 52 includes a display of call members when the user of the terminal device 20 made a call in the past using a call application. For example, the latest history of the call history display 52 shows that a call with other call members of the user of the terminal device 20, Pyama, Qkawa, and Rtani, was made for 12 minutes from 10:32 on January 23, 2022.

[0064] The call group screen 50 includes a selection start button 53. When the control unit 21 receives an operation input to the selection start button 53 at the input unit 25, the control unit 21 causes the output unit 24 to display a call member selection screen 60 illustrated in FIG.

[0065] The call member selection screen 60 includes a display of other workers who are candidates for call partners. The control unit 21 displays workers included in the latest list of workers participating in the specified case on the call member selection screen 60 as candidate call partners. The display of each candidate may include the name of each candidate. The display of each candidate may include the name of the organization, such as the company, to which each candidate belongs. The display of each candidate may include an image set by each candidate. The image set by each candidate may include a facial photo of each candidate.

[0066] Each candidate on the call member selection screen 60 is associated with either a selected button 61 or an unselected button 62. The selected button 61 indicates that the candidate associated with the selected button 61 has been selected as a call member for a newly started call. In the example of FIG. 5, Pyama and Qgawa have been selected as call members. The state in which they are selected as call members is also referred to as a selected state. The unselected button 62 indicates that the candidate associated with the unselected button 62 has not been selected as a call member for a newly started call. In the example of FIG. 5, Rtani has not been selected as a call member. The state in which they are not selected as a call member is also referred to as an unselected state.

[0067] When the input unit 25 receives an operation input for the unselected button 62, the control unit 21 may change the unselected button 62 to the selected button 61. Conversely, when the input unit 25 receives an operation input for the selected button 61, the control unit 21 may change the selected button 61 to the unselected button 62. In other words, when the input unit 25 receives an operation input for each candidate, the control unit 21 may switch the state of the candidate between a selected state and an unselected state.

[0068] The control unit 21 may display an unselected button 62 in association with the candidates when initially displaying them on the call member selection screen 60. The control unit 21 may display a selected button 61 in association with at least some of the candidates when initially displaying each candidate on the call member selection screen 60.

[0069] When the control unit 21 receives an operation input for one call history included in the call history display 52 at the input unit 25, the control unit 21 may display the call members of that call history on the call member selection screen 60 as candidates for call members for a newly started call. When displaying the workers participating in the specified case on the call member selection screen 60, the control unit 21 may associate a selected button 61 with the call members of the call history and an unselected button 62 with workers other than the call members of the call history. The control unit 21 may display only the call members of the call history on the call member selection screen 60.

[0070] The call member selection screen 60 includes a call start button 63. In the example of Fig. 5, the call start button 63 includes a display of the number of people selected as call members from among the call partner candidates. When Pyama and Qkawa are selected as call members, the call start button 63 includes a display of (2) corresponding to the number of people selected as call members. The call start button 63 does not have to include a display of the number of people selected as call members.

[0071] Returning to Fig. 2, the control unit 21 starts a new call with the selected call members (step S6). Note that the procedure of step S6 is executed on the premise that at least one call member has been selected in the procedure of step S5.

[0072] Specifically, when the control unit 21 receives an operation input to the call start button 63 at the input unit 25, the control unit 21 confirms the candidates associated with the selected button 61 on the call member selection screen 60 as call members, and starts a new call. In other words, the control unit 21 allows the user to select call members for the new call by selecting and then confirming the workers included in the latest list. The user can easily select call members by performing the procedure of selecting and then confirming the workers included in the latest list. In addition, the user is less likely to make a mistake in selecting call members. As a result, the convenience of communication between workers is improved.

[0073] The control unit 21 causes the output unit 24 to display a call screen 70 as exemplified in FIG.

[0074] The call screen 70 includes a display of an icon 71L or 72L representing a call member. The icon 71L represents Pyama among the call members. The icon 72L represents Qkawa among the call members. The icon 71L or 72L may be displayed in a different manner when the corresponding call member is speaking.

[0075] 6 includes an exit button 73, a microphone button 74, a camera button 75, a pointer button 76, and a photograph button 77. The call screen 70 does not necessarily have to include at least some of these buttons.

[0076] The exit button 73 is used by the user of the terminal device 20 to end the call and exit the call.

[0077] The microphone button 74 is used to select whether to mute the microphone of the terminal device 20. When the microphone of the terminal device 20 is muted, the voice of the user of the terminal device 20 is not transmitted to the terminal devices 20 of the other call members. When the microphone of the terminal device 20 is not muted, the user's voice is transmitted to the terminal devices 20 of the other call members. When the user's voice is transmitted to the terminal devices 20 of the other call members, the user's voice is output in the terminal devices 20 of the other call members.

[0078] The camera button 75 is used to transmit an image captured by the photographing unit 26 of the terminal device 20 to the terminal device 20 of another call member to share the image. An image shared between call members is displayed as a shared image 79 on the call screen 70. Each call member may point to a specific location on the shared image 79 with a pointer 71P or 72P.

[0079] The pointer button 76 is used by the user of the terminal device 20 to select whether to display a pointer 71P or 72P on the call screen 70 for pointing to a specific location on the call screen 70. In the call screen 70 illustrated in FIG. 6, the pointer 71P is displayed at the location pointed to by Pyama. Also, the pointer 72P is displayed at the location pointed to by Qkawa. The pointer 71P may be displayed in combination with an icon 71I indicating that the pointer 71P corresponds to Pyama. The pointer 72P may be displayed in combination with an icon 72I indicating that the pointer 72P corresponds to Qkawa. The icon 71I or 72I may include the name of each call member.

[0080] The photographing button 77 is used by the user of the terminal device 20 to take a still image of the scene using the photographing unit 26 while the user is on a call.

[0081] Returning to FIG. 2, the control unit 21 acquires information during the call (step S7). The control unit 21 may acquire a photograph taken by the photographing unit 26 as information. The control unit 21 may acquire audio data of the call, or video data of an image displayed during the call as information. The control unit 21 may acquire data such as text data or image data entered during the call as information. The control unit 21 may acquire text data based on the contents of the call as information. By being able to acquire information during a call, communication between workers can be easily recorded. As a result, the convenience of communication between workers is improved.

[0082] When the control unit 21 acquires information during the call, it stores the acquired information in the database 30 (step S8). The control unit 21 may store the information in the database 30 in association with the case specified when the call is started. By being able to store the information acquired during the call in association with the case, the contact records can be more easily utilized. As a result, the convenience of communication between workers is improved.

[0083] The control unit 21 determines whether to end the call (step S9). The control unit 21 may determine that the call is to be ended when the input unit 25 receives an operation input to the exit button 73 on the call screen 70. The control unit 21 may also determine that the call is to be ended when the other call members exit the call and the user is the only call member remaining.

[0084] When the control unit 21 determines not to end the call (step S9: NO), the control unit 21 returns to the procedure of step S7 to continue the call. When the control unit 21 determines to end the call (step S9: YES), the control unit 21 ends the call and ends the execution of the procedure of the flowchart in FIG.

[0085] (summary) As described above, in the construction management system 1 according to the present disclosure, the terminal device 20 can display an updated list of workers participating in a project and allow the user to select call members from the candidates included in the updated list.

[0086] Here, as a system according to a comparative example, it is possible that a call application creates a call group in advance. However, the call group created in advance may not match the latest list of workers participating in the project. Therefore, the terminal device 20 of the construction management system 1 according to the present disclosure allows the user to easily contact other workers participating in the same project by being able to select call members from the latest list. As a result, the convenience of communication between workers participating in the project is improved.

[0087] Furthermore, in the construction management system 1 according to the present disclosure, the terminal device 20 obtains the latest list of workers through a call application, so that the user of the terminal device 20 does not need to check the workers who will participate in the project in the construction management system 1 and input the call members into the call application by the user himself / herself. Since the user does not need to check the workers who will participate in the project in the construction management system 1, there is no need to keep the construction management application open on the terminal device 20. As a result, the processing load on the terminal device 20 used by the user can be reduced.

[0088] In addition, in the construction management system 1 according to the present disclosure, the user of the terminal device 20 can select call members from the latest list of workers each time a call is made, and therefore there is no need to create and manage many call groups with different combinations of call members. By eliminating the need to manage many call groups, the user of the terminal device 20 can easily contact other workers participating in the project. As a result, the convenience of communication between workers participating in the project is improved.

[0089] (Other embodiments) Hereinafter, another embodiment of the construction management system 1 according to the present disclosure will be described.

[0090] <Selection of call members considering the progress of the process> The construction management information includes a schedule for the project. The schedule for the project includes information regarding the progress of at least one step included in the project. The construction management information may also include an updated list of workers participating in the project as a whole, as well as an updated list of workers participating in each step included in the project.

[0091] The control unit 21 may execute a procedure for acquiring a schedule of the project. That is, the call method may further include a step of acquiring a schedule of the project. The control unit 21 may also receive an input for specifying a process in addition to specifying the project. When a process included in the project is specified, the control unit 21 may acquire a list of workers who will participate in the specified process.

[0092] The control unit 21 may display the worker in charge of the ongoing process in the work schedule and other workers in a manner that allows the user to distinguish and identify them on the call member selection screen 60. By displaying the worker in charge of the ongoing process and other workers in a manner that allows the user to distinguish and identify them, the user can easily select a call member. As a result, the convenience of communication between workers is improved.

[0093] The control unit 21 may display the worker who is in charge of the process in progress in the work schedule of the case in a selected state from the beginning on the call member selection screen 60. By selecting the worker who is in charge of the process in progress from the beginning, the user's operation input can be reduced. As a result, the convenience of communication between the workers is improved.

[0094] The control unit 21 may display an unselected button 62 in association with the candidates when initially displaying them on the call member selection screen 60. The control unit 21 may display a selected button 61 in association with at least some of the candidates when initially displaying each candidate on the call member selection screen 60.

[0095] When the control unit 21 receives an operation input for one call history included in the call history display 52 at the input unit 25, the control unit 21 may display the call members of that call history on the call member selection screen 60 as candidates for call members for a newly started call. When displaying the workers participating in the specified case on the call member selection screen 60, the control unit 21 may associate a selected button 61 with the call members of the call history and an unselected button 62 with workers other than the call members of the call history. The control unit 21 may display only the call members of the call history on the call member selection screen 60.

[0096] <Mode for executing only the calling application> The control unit 21 may execute the calling method exemplified in Fig. 2 in a state where only the calling application is running without executing the construction management application. In this case, the control unit 21 accepts an input for specifying a case in the calling application as a case designation step in step S1. The control unit 21 determines that a call start operation has been performed when an input for starting a call in the calling application is accepted in a step of determining a call start operation in step S2. The control unit 21 acquires, from the calling application, the latest list of members participating in the designated case, which is included in the construction management information stored in the database 30 as a list acquisition step in step S3. The control unit 21 executes the operations from step S4 onwards in the calling application, as described above.
