[Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 11-286936 Summary of the Invention [Problem to be solved by the invention]

However, in the above-mentioned conventional technology, as described above, although an alarm is issued when the measurement data is equal to or greater than the danger value, no information is output when the measurement data is not equal to or greater than the danger value, so that it is difficult to grasp the state of the managed objects in detail and easily when the measurement data is not equal to or greater than the danger value, and there is room for improvement from the viewpoint of improving the manageability of the managed objects.

First, [I] the basic concept of the embodiment will be described, then [II] the specific contents of the embodiment will be described, and finally, [III] modified examples of the embodiment will be described. However, the present invention is not limited to the embodiment.

[0022] [I] Basic Concept of the Embodiment First, a basic concept of the embodiment will be described. The embodiment generally relates to a management system for managing managed objects.

[0023] Here, the term "managed object" refers to an object managed by the management system. The specific type of the "managed object" is arbitrary, but the concept includes, for example, construction materials constituting a structure (for example, floor materials, pillar materials, wall materials, beam materials, retaining materials, etc.), the ground surrounding the structure, industrial products manufactured in factories, etc., patients and animals receiving medical treatment, etc., but in the embodiment, it will be described as the construction materials constituting the structure and the ground surrounding the structure.

[0024] Furthermore, the specific structure and type of the "structure" are arbitrary, but the concept includes, for example, architectural structures such as office buildings, public facilities, commercial facilities, and apartment buildings (one example is an apartment building), as well as civil engineering structures such as bridges and tunnels, and in the embodiment, it will be described as an office building under construction that makes use of some existing construction materials.

[0025] [II] Specific Contents of the Embodiments Next, the specific contents of the embodiment will be described.

[0026] (composition) First, a configuration of a management system 1 according to an embodiment and a configuration of a structure (not shown) to which the management system 1 is applied will be described.

[0027] (Composition-Structure) First, the configuration of the structure will be described.

[0028] The structure is, for example, a steel-framed (or reinforced concrete) architectural structure (specifically, an office building under construction with multiple floors (including underground floors)) and includes flooring, columns, beams, wall materials, and retaining materials (all not shown).

[0029] Among these, the flooring constitutes the floors of the structure, and a plurality of them are arranged in parallel in the vertical direction at intervals. The pillars support the flooring, and a plurality of them are arranged between the floorings (i.e., the space between each floor of the structure). The beams support the flooring, and a plurality of them are arranged at positions where they can abut against the underside of each flooring, or between floorings on the same floor. The wall materials are for separating the floorings, and a plurality of them are arranged between the floorings. The earth retaining materials are for preventing the collapse of the ground in the area where the structure is constructed (hereinafter referred to as the "construction target area") or in the surrounding area, and are made of, for example, known earth retaining materials (one example is an earth retaining material having a ground improvement body and a core material), and a plurality of them are buried in the construction target area.

[0030] (Configuration - Structure - Other configurations) Furthermore, measuring instruments (not shown) are provided on the multiple floor materials, multiple pillar materials, multiple earth retaining materials, and the ground in the construction area, which are the objects of management.

[0031] The measuring device is a measuring means that measures the state of the managed object and transmits the measured data (that is, data indicating the state of the managed object; hereinafter, referred to as "measurement data") to the management device 10, which will be described later.

[0032] Here, the "state of the managed object" refers to the state of the managed object at a certain point in time, and is a concept including, for example, the deformation state, displacement state, tilt state, and / or stress state (as examples, axial force state, water pressure state) of the managed object.

[0033] In addition, the specific configuration of the measurement data is arbitrary, but in the embodiment, the measurement data includes management target identification information for identifying the management target, measurement value information indicating the measurement value measured by the measuring instrument, and measurement time information indicating the measurement time when the measurement value was measured, etc. However, without being limited to this, the measurement data may include only the management target identification information and the measurement value information, for example.

[0034] Furthermore, this measuring instrument is constructed using, for example, known measuring instruments, and specifically, it is constructed using surveying equipment (one example is a total station, etc.), level meters (one example is an auto level, etc.), inclinometers capable of three-dimensional measurement (one example is a multi-stage inclinometer, an insertion inclinometer, a fixed inclinometer, etc.), etc.

[0035] At least one of these measuring instruments is provided on or near the object to be managed. Specifically, the surveying instruments are provided near the floor materials, pillar materials, and / or ground of the construction area to be managed. The level gauges are provided on the upper surface of the floor materials and / or ground of the construction area to be managed. Multiple inclinometers are attached to the retaining materials to be managed.

[0036] (Configuration Management System) Next, there will be described the management system 1. Fig. 1 is a conceptual diagram showing a management system 1 according to an embodiment of the present invention.

[0037] The management system 1 is a system for managing managed objects (specifically, multiple floor materials, multiple pillar materials, multiple retaining materials, and the ground in the construction area), and is equipped with a management device 10 and a terminal device 20, as shown in Figure 1.

[0038] 1 shows only one terminal device 20, but in reality the management system 1 is configured to include a terminal device 20 possessed by each of a plurality of users (in the embodiment, workers engaged in the construction of a structure, etc.) and a common management device 10 capable of communicating with the plurality of terminal devices 20. In the following, the terminal device 20 possessed by one user will be described, and descriptions of the terminal devices 20 possessed by other users will be omitted.

[0039] As for the connection of the components constituting the management system 1, in this embodiment, a management device 10 and a terminal device 20 are connected via a network 2 so as to be able to communicate with each other.

[0040] (Configuration-Management System-Management Device) The management device 10 is a device for managing measurement data measured by a measuring instrument, and as shown in Fig. 1, includes a management-side communication unit 11, a management-side control unit 12, and a management-side storage unit 13. Note that the management device 10 can be configured, for example, by a known cloud server, and therefore a detailed description thereof will be omitted.

[0041] (Configuration-Management system-Management device-Management communication unit) The management side communication unit 11 is a management side communication means for communicating between the terminal device 20 and / or an external device not shown (e.g., a management side terminal device, an image generating device, a relay device, etc. described below) and the management device 10, and is configured using a known communication means for communicating using a wireless communication network and / or a wired communication network.

[0042] (Configuration-Management system-Management device-Management control unit) The management side control unit 12 is a management side control means that controls the management device 10, and specifically, is a computer equipped with a CPU, various programs that are interpreted and executed on the CPU (including basic control programs such as an OS, and application programs that are launched on the OS and realize specific functions), and an internal memory such as a RAM for storing programs and various data (the same applies to the terminal side control unit 25 of the terminal device 20 described later).

[0043] As shown in FIG. 1, the management control unit 12 conceptually includes an acquisition unit 12a, a calculation unit 12b, a linking unit 12c, and a provision unit 12d.

[0044] The acquiring unit 12a is an acquiring unit that acquires measurement data.

[0045] The calculation unit 12b is a calculation means that calculates the difference between the measurement data acquired by the acquisition unit 12a (specifically, the measurement value of the measurement value information) and a reference value acquired by a predetermined method.

[0046] Here, the "reference value" means a value that is the basis for evaluating measurement data, and is a concept that includes, for example, a design value calculated using a known calculation method, an analytical value calculated using a known analysis method (one example is finite element analysis), and an experimental value obtained by a known test method, etc. The method for setting the reference value is arbitrary, but it is desirable to set it differently depending on, for example, the type of measuring instrument or the type or size of the object to be managed.

[0047] The linking unit 12c is a linking means for linking the difference information, the display image, and the authentication information with each other.

[0048] Here, "difference information" means information indicating the difference calculated by the calculation unit 12b. In addition, the specific configuration of the difference information is arbitrary, but in the embodiment, it is configured to include difference value information indicating a difference value between the measurement value of the measurement value information and a reference value, measurement time information, and management target identification information. However, without being limited to this, for example, it may be configured to include only difference value information and management target identification information.

[0049] Moreover, the term "display image" refers to an image generated by a predetermined method and including a managed object image related to the managed object. In the embodiment, each managed object image included in the display image is stored in association with managed object identification information (to be described later) and managed object position information indicating the coordinate positions of each node constituting the managed object image.

[0050] Furthermore, the method for generating this display image is arbitrary, but for example, a three-dimensional image (e.g., a three-dimensional BIM model image, etc.) may be generated using a known image generation method (one example is BIM (Building Information Modeling), etc.) in the management device 10 or an external device (e.g., a management side terminal device or image generation device described later), and the generated image may be used as the display image to be generated.

[0051] In addition, "authentication information" refers to information that enables differential information and / or a display image to be provided, and includes, for example, QR code information (registered trademark), barcode information (e.g., normal barcode, two-dimensional barcode, three-dimensional barcode, etc.), etc.

[0052] The providing unit 12d is a providing means for providing the terminal device 20 with difference information and / or a display image linked to the authentication information on the condition that the authentication information has been acquired from the terminal device 20. Details of the process executed by the management-side control unit 12 will be described later.

[0053] (Configuration-Management system-Management device-Management side memory unit) The management side storage unit 13 is a management side storage means for recording programs and various data necessary for the operation of the management device 10, and is configured, for example, using a hard disk (not shown) as an external recording device. However, instead of or together with the hard disk, any other recording medium can be used, including a magnetic recording medium such as a magnetic disk, an optical recording medium such as a DVD or a Blu-ray disk, or an electric recording medium such as a Flash Rom, a USB memory, or an SD card (the same applies to the terminal side storage unit 26 of the terminal device 20 described later).

[0054] As shown in FIG. 1, the management storage unit 13 also includes a display image database (hereinafter, the database will be referred to as "DB") 13a.

[0055] The display image DB 13a is a display image storage means for storing a display image associated with difference information.

[0056] Fig. 2 is a diagram showing an example of the configuration of the display image DB 13a. As shown in Fig. 2, the display image DB 13a stores the items "management number information", "difference information", "display image", and "authentication information" in association with information corresponding to each item. The item "difference information" further includes items related to the difference information, such as "difference value information", "measurement time information", and "management subject identification information".

[0057] Among these, the information corresponding to the item "Management number information" is management number information indicating a management number for managing related difference information, display image, and authentication information, such as the management number "0001" shown in Figure 2.

[0058] Moreover, information corresponding to the item "Difference information" is difference information. Of these, information corresponding to the item "Difference value information" is difference value information, such as "X direction = 3 mm, Y direction = 9 mm, Z direction = 5 mm" which is the difference between the displacement amount of the retaining material measured by the inclinometer and the reference value. Moreover, information corresponding to the item "Measurement time information" is measurement time information, such as "2021 / 3 / 26 / 10:30" (meaning 10:30 on March 26, 2021), which is the measurement time of the inclinometer. Moreover, information corresponding to the item "Management target identification information" is management target identification information, such as "10001", which is the ID number of the management target.

[0059] Moreover, information corresponding to the item "display image" is information indicating a display image (hereinafter, referred to as "display image information"), and corresponds to, for example, "PIC0001.JPG" which is the display image shown in FIG.

[0060] Moreover, information corresponding to the item "authentication information" is authentication information, and corresponds to, for example, the QR code shown in FIG.

[0061] (Configuration-Management System-Terminal Device) Returning to Fig. 1, the terminal device 20 is a device carried by a user (specifically, the worker) and performs various controls based on information received from the management device 10, and as shown in Fig. 1, includes a terminal operation unit 21, a terminal communication unit 22, a terminal display unit 23, a terminal power supply unit 24, a terminal control unit 25, and a terminal storage unit 26. Note that the terminal device 20 can be configured, for example, by a known mobile terminal (such as a smartphone or tablet terminal) or a stationary personal computer, and therefore a detailed description thereof will be omitted.

[0062] (Configuration-Management system-Terminal device-Terminal side communication unit) The terminal side communication unit 22 is a terminal side communication means for communicating between the management device 10 and the terminal device 20 via the network 2, and is configured using, for example, a known communication means for communicating using a wireless communication network or a wired communication network.

[0063] (Configuration-Management system-Terminal device-Terminal side operation unit) The terminal side operation unit 21 is a terminal side operation means that accepts operation input to the terminal device 20, and is configured using known operation means such as various switches and a touch pad.

[0064] (Configuration-Management system-Terminal device-Terminal display unit) The terminal-side display unit 23 is a display means for displaying difference information and a display image in association with each other, and is also a terminal-side display means for displaying various information under the control of the terminal-side control unit 25. The terminal-side display unit 23 is configured using, for example, a known display means (a display, as one example).

[0065] (Configuration - Management system - Terminal device - Terminal side power supply unit) The terminal side power supply unit 24 is a terminal side power supply means that supplies power supplied from a commercial power supply or a battery (not shown) to each unit of the terminal device 20.

[0066] (Configuration-Management system-Terminal device-Terminal side control unit) The terminal-side control unit 25 is a terminal-side control means that controls the terminal device 20. The process executed by the terminal-side control unit 25 will be described in detail later.

[0067] (Configuration-Management system-Terminal device-Terminal side memory unit) The terminal side storage unit 26 is a terminal side storage means for recording programs and various data required for the operation of the terminal device 20.

[0068] (Management process) Next, a management process executed by the management system 1 configured as above will be described.

[0069] FIG. 3 is a flowchart of the management process related to the management device 10 according to the embodiment (in the following description of each process, steps are abbreviated as "S"). FIG. 4 is a flowchart of the management process related to the terminal device 20 according to the embodiment. FIG. 5 is a diagram showing an example of display of difference information and a display image. FIG. 6 is an enlarged view of the area of ​​the managed image in FIG. 5. FIG. 7 is a diagram showing an example of display of difference information and a display image, where (a) is a diagram showing only difference information related to the ground of the construction target area in FIG. 5, and (b) is a diagram showing a different time series from (a). FIG. 8 is a diagram showing an example of display of difference information and a display image, showing only difference information related to the earth retaining material in FIG. 5. FIG. 9 is a diagram showing an example of display of difference information and a display image, showing only difference information related to the pillar material.

[0070] The management process is a process for managing the objects to be managed (specifically, a plurality of floor materials, a plurality of pillar materials, a plurality of retaining materials, and the ground of the construction target area). The timing for executing this management process is arbitrary, but in the embodiment, it is described as being started after the power of the management device 10 and the terminal device 20 is turned on.

[0071] In addition, regarding the premise of the management process, in the embodiment, it is described as being executed during the period when the structure is under construction, and measuring instruments are attached to at least one of the multiple floor materials, multiple pillar materials, multiple retaining materials, and the ground in the construction area that are to be managed.

[0072] When the measurement process is started, as shown in FIG. 3, the management side control unit 12 of the management device 10 determines whether or not the timing for acquiring measurement data (hereinafter referred to as "first acquisition timing") has arrived at SA1.

[0073] While the method for determining whether the first acquisition timing has arrived is arbitrary, in the embodiment, the determination is made based on whether a periodic timing (for example, a timing at 10-minute intervals) has arrived and whether acquisition instruction information indicating an instruction to acquire measurement data has been received from the management side terminal device. Here, if the periodic timing has arrived or acquisition instruction information has been received, it is determined that the first acquisition timing has arrived, and if the periodic timing has not arrived or acquisition instruction information has not been received, it is determined that the first acquisition timing has not arrived. Note that the "management side terminal device" is a device held by a manager who manages the construction of a structure, and is configured approximately the same as terminal device 20, for example.

[0074] Then, if the management side control unit 12 of the management device 10 determines that the first acquisition timing has arrived (SA1, Yes), it transitions to SA2, and if it determines that the first acquisition timing has not arrived (SA1, No), it transitions to SA9.

[0075] In SA2, the acquisition unit 12a of the management device 10 acquires the measurement data.

[0076] The method of acquiring this measurement data is arbitrary, but for example, it may be acquired by receiving the measurement data directly from the measuring instrument, or it may be acquired by indirectly receiving the measurement data from an external device (e.g., a management terminal device or a relay device) that acquired the measurement data from the measuring instrument.

[0077] In SA3, the management side control unit 12 of the management device 10 acquires a reference value.

[0078] The method of acquiring this reference value is arbitrary, and for example, it may be acquired from the management side storage unit 13. Specifically, from a reference value table (not shown) provided in the management side storage unit 13, in which management object identification information and reference value information indicating a reference value are stored in association with each other, reference value information corresponding to the management object identification information included in each measurement data acquired by SA2 may be extracted, and the value of the extracted reference value information may be acquired as the reference value to be acquired. However, without being limited to this, for example, it may be acquired by receiving from an external device (for example, a management side terminal device).

[0079] In SA4, the calculation unit 12b of the management device 10 calculates the difference between the measurement data acquired in SA2 and the reference value acquired in SA3.

[0080] Specifically, the calculation is performed by subtracting the reference value acquired in SA3 from the measurement value of the measurement value information of each measurement data acquired in SA2.

[0081] At SA5, the management side control unit 12 of the management device 10 acquires a display image.

[0082] The method of acquiring this display image is arbitrary, but for example, it may be acquired from the management side storage unit 13. Specifically, it may be acquired as the display image to be acquired from a display image table (not shown) provided in the management side storage unit 13, which stores display images generated in advance by the management device 10, and a display image selected by the above-mentioned administrator via the management side terminal device (for example, a display image including all managed object images related to the managed object corresponding to the managed object identification information of each measurement data acquired by SA2) may be acquired. Alternatively, it may be acquired by receiving from an external device (for example, a management side terminal device or an image generating device).

[0083] At SA6, the management-side control unit 12 of the management device 10 generates authentication information corresponding to the display image acquired at SA5.

[0084] Specifically, the authentication information is generated based on predetermined information (e.g., information related to a file key) received from the management terminal device using a known method. Alternatively, the authentication information may be automatically generated using a known method.

[0085] In SA7, the linking unit 12c of the management device 10 links the difference information indicating the difference calculated in SA4, the display image acquired in SA5, and the authentication information generated in SA6 to each other, and stores the linked difference information, display image, and authentication information in the display image DB 13a, as shown in Figure 2.

[0086] The method of linking the difference information, the display image, and the authentication information is arbitrary, but for example, the difference information, the display image, and the authentication information may be automatically linked using a known method. Alternatively, the difference information, the display image, and the authentication information may be semi-automatically linked based on a predetermined operation by the administrator accepted via the administrator terminal device.

[0087] Returning to FIG. 3, in SA8, the management-side control unit 12 of the management device 10 transmits authentication information to the terminal device 20, and then the process proceeds to SA1.

[0088] While the method of transmitting this authentication information is arbitrary, in the embodiment, only the authentication information stored in the display image DB 13a immediately before the processing of SA8 is transmitted. This allows the terminal device 20 to obtain the latest difference information and / or display image. However, without being limited thereto, for example, all of the authentication information stored in the display image DB 13a may be transmitted.

[0089] Next, as shown in FIG. 4, at SB1, the terminal side control unit 25 of the terminal device 20 determines whether or not the authentication information transmitted at SA8 has been acquired (received).

[0090] Then, if the terminal side control unit 25 of the terminal device 20 determines that authentication information has been acquired (SB1, Yes), it transitions to SB2, and if it determines that authentication information has not been acquired (SB1, No), it transitions to SB3.

[0091] At SB2, the terminal-side control unit 25 of the terminal device 20 determines whether or not the timing for acquiring management information (to be described later) (hereinafter referred to as "second acquisition timing") has arrived.

[0092] While the method for determining whether or not the second acquisition timing has arrived is arbitrary, in the embodiment, the determination is made based on whether or not a predetermined operation has been accepted via the terminal side operation unit 21, or whether or not a regular timing (for example, a timing at one-day intervals) has arrived. Here, if the predetermined operation has been accepted or the regular timing has arrived, it is determined that the second acquisition timing has arrived, and if the predetermined operation has not been accepted or the regular timing has arrived, it is determined that the second acquisition timing has not arrived.

[0093] Then, the terminal side control unit 25 of the terminal device 20 waits until it is determined that the second acquisition timing has arrived (SB2, No), and transitions to SB4 if it is determined that the second acquisition timing has arrived (SB2, Yes).

[0094] In SB3, the terminal side control unit 25 of the terminal device 20 judges whether or not the timing for reacquiring the management information described below (hereinafter referred to as the "third acquisition timing") has arrived. Here, "reacquiring" means reacquiring the management information described below that has been acquired in the past.

[0095] The method of determining whether or not the third acquisition timing has arrived is arbitrary, but in the embodiment, the determination may be made in the same manner as the method of determining whether or not the second acquisition timing has arrived. Alternatively, when there are multiple pieces of management information that have been previously acquired, which will be described later, a display area (hereinafter referred to as the "third acquisition display area") may be generated on the screen of the terminal side display unit 23, and multiple pieces of authentication information corresponding to the management information, which will be described later, may be displayed in the generated third acquisition display area, and the determination may be made based on whether or not the corresponding authentication information has been specified via the terminal side operation unit 21. Here, when the corresponding authentication information has been specified, it is determined that the third acquisition timing has arrived, and when the corresponding authentication information has not been specified, it is determined that the third acquisition timing has not arrived.

[0096] Then, if the terminal side control unit 25 of the terminal device 20 determines that the third acquisition timing has arrived (SB3, Yes), it transitions to SB4, and if it determines that the third acquisition timing has not arrived (SB3, No), it transitions to SB6.

[0097] In SB4, the terminal side control unit 25 of the terminal device 20 transmits the authentication information to the management device 10.

[0098] The method of transmitting this authentication information is arbitrary, but in this embodiment, it is obtained as follows. That is, when it is determined that the second acquisition timing has arrived in SB2, the authentication information most recently acquired in SB1 is transmitted. Also, when it is determined that the third acquisition timing has arrived in SB3, the authentication information most recently acquired in SB1 or, as described above, authentication information specified via the terminal side operation unit 21 from among the authentication information acquired in the past is transmitted.

[0099] Returning to FIG. 3, at SA9, the management-side control unit 12 of the management device 10 determines whether or not authentication information has been acquired (received).

[0100] Then, if the management side control unit 12 of the management device 10 determines that authentication information has been acquired (SA9, Yes), it transitions to SA10, and if it determines that authentication information has not been acquired (SA9, No), it transitions to SA11.

[0101] In SA10, the providing unit 12d of the management device 10 transmits information including the difference information and / or the display image (hereinafter referred to as "management information") to the terminal device 20, and then the process proceeds to SA11.

[0102] Specifically, from the difference information and display images stored in the display image DB13a, the difference information and display image corresponding to the authentication information acquired by SA9 are extracted, and information including the extracted difference information and display image, the authentication information acquired by SA9, and the measurement data and reference value information used in calculating the extracted difference information is transmitted as management information (i.e., on the condition that authentication information has been acquired from the terminal device 20, the difference information and display image linked to the authentication information are provided to the terminal device 20).

[0103] The method of transmitting the management information is arbitrary, but for example, the transmission of the management information may be restricted from the viewpoint of increasing the security of the management information. Specifically, when transmitting the management information multiple times to the same terminal device 20, the transmission of the management information may be stopped when the number of times reaches a predetermined number, the transmission of the management information may be stopped when the set password cannot be verified, and / or the transmission of the management information may be stopped when a predetermined time has elapsed since the authentication information was transmitted at SA8. However, the present invention is not limited to this, and for example, the management information may be transmitted on the condition that the authentication information is acquired at SA9 without restricting the transmission of the management information.

[0104] In SA11, the management-side control unit 12 of the management device 10 judges whether or not the timing for ending the management process (hereinafter, referred to as "first ending timing") has arrived.

[0105] The method for determining whether or not this first end timing has arrived is arbitrary, but in the embodiment, the determination is made based on whether or not end instruction information indicating to end the management process has been received from the management terminal device, and if end instruction information has been received, it is determined that the first end timing has arrived, and if end instruction information has not been received, it is determined that the first end timing has not arrived.

[0106] Then, the management side control unit 12 of the management device 10 ends the management process when it is determined that the first end timing has arrived (SA11, Yes).On the other hand, when it is determined that the first end timing has not arrived (SA11, No), it moves to SA1, and thereafter similarly repeats the processes from SA1 to SA11.

[0107] Next, as shown in FIG. 4, at SB5, the terminal side control section 25 of the terminal device 20 determines whether or not the management information transmitted at SA10 has been acquired (received).

[0108] Then, the terminal side control section 25 of the terminal device 20 waits until it is determined that the management information has been acquired (SB5, No), and proceeds to SB6 if it is determined that the management information has been acquired (SB5, Yes).

[0109] At SB6, the management-side control unit 12 of the management device 10 determines whether or not the timing for displaying the difference information and the display image (hereinafter referred to as "display timing") has arrived.

[0110] While the method for determining whether or not this display timing has arrived is arbitrary, in the embodiment, the determination is made based on whether or not display instruction information indicating an instruction to display the difference information and the display image has been received from the management side terminal device, or whether or not a predetermined time has elapsed since the management information was acquired by SB5. Here, if the display instruction information has been received, or the above-mentioned predetermined time has elapsed, it is determined that the display timing has arrived, and if the display instruction information has not been received, or the above-mentioned predetermined time has not elapsed, it is determined that the display timing has not arrived.

[0111] Then, if the terminal side control unit 25 of the terminal device 20 determines that the display timing has arrived (SB6, Yes), it proceeds to SB7, and if it determines that the display timing has not arrived (SB6, No), it proceeds to SB8.

[0112] In SB7, the terminal control unit 25 of the terminal device 20 causes the terminal display unit 23 to display the difference information and the display image (specifically, the difference information and the display image provided by the providing unit 12d), and then proceeds to SB8.

[0113] The method of displaying this difference information and the display image is arbitrary, but in this embodiment, they are displayed as follows.

[0114] That is, in the virtual space constructed in the management device 10, the difference information and the display image included in the management information acquired by the SB5 are displayed in association with each other.

[0115] Specifically, as shown in Figures 5 to 9, in the virtual space VS, in positions adjacent to various managed object images included in the display image DI (specifically, managed object image MI1 related to floor materials, managed object image MI2 related to retaining materials, managed object image MI3 related to the ground of the construction target area, and managed object image MI4 related to pillar materials), differential value information of difference information D corresponding to the managed object identification information linked to the managed object image is displayed as arrow-like figures and / or characters. In particular, when the managed object image is a construction member, the center line (center position of the managed object) of the managed object image is identified based on the managed object position information linked to the managed object image, and the differential value information is displayed in a position adjacent to the identified center line position.

[0116] As an example, when displaying difference information D related to the floor materials, earth retaining materials, and the ground of the construction target area, which are the objects of management, in a display image DI showing a portion of a structure from the first floor above ground to the basement floor, the difference information D may be displayed in the vicinity of the managed images MI1 to MI3 related to the floor materials, earth retaining materials, and the ground of the construction target area, respectively, as shown in Fig. 5 and Fig. 6. In particular, the difference information D related to the earth retaining materials may be displayed in the vicinity of the center line of the street.

[0117] This type of display allows the state of the managed object to be grasped in detail and easily (specifically, the details of the comparison between the measured values ​​of the managed object and the reference values ​​can be easily grasped), and the manageability of the managed object can be improved (for example, it becomes possible to quickly take measures to reinforce the managed object or to change the design of the structure, etc.). Furthermore, the difference information can be presented in association with the center line of the managed object image, and the visibility of the difference information and the managed object image can be improved (for example, the positional relationship between the difference information and the managed object image corresponding to the difference information can be accurately and easily visually recognized).

[0118] Furthermore, a plurality of pieces of difference information (specifically, difference value information) having different time series are displayed in a switchable manner according to the time series.

[0119] Specifically, as described below, by repeating the processing from SB1 to SB8, when multiple pieces of management information with different time series are acquired in SB5, a predetermined operation is performed via the terminal side operation unit 21, and the multiple pieces of difference value information contained in the multiple pieces of management information are switched and displayed according to the time series.

[0120] As an example, in a display image DI showing a portion of a structure extending from the first floor above ground to the basement floor, when differential information D relating to the ground of a construction target area to be managed is displayed, the differential value information relating to the ground of the multiple construction target areas may be displayed in chronological order by switching between them, as shown in Figures 7(a) and 7(b).

[0121] This type of display makes it possible to present time-series difference information according to needs, and to easily grasp the state of a specific managed object.

[0122] Furthermore, a plurality of pieces of difference information (specifically, difference value information) with different measurement items are displayed in a switchable manner according to the measurement item. In the embodiment, the "measurement item" is set for each type of measuring instrument, each measurement direction of the measuring instrument, and / or each floor of the structure.

[0123] Specifically, a display area (hereinafter referred to as the "measurement item display area") is generated on the screen of the terminal side display unit 23, and multiple pieces of measurement item information indicating measurement items are displayed in the generated measurement item display area, and when any one of the measurement item information is identified via the terminal side operation unit 21, only the difference value information corresponding to the measurement item of the identified measurement item information is displayed.

[0124] As an example, in a display image DI showing a portion of a structure extending from the first floor above ground to the basement floor, when only differential information D related to the earth retaining material to be managed is displayed, if the measuring instrument provided on the earth retaining material is an inclinometer, differential value information corresponding to items whose measurement directions of the inclinometer are the X and Y directions may be displayed as shown in Fig. 8. Also, in a display image DI showing a portion of an intermediate floor above ground in a structure, when only differential information D related to a column material of a specific intermediate floor above ground to be managed is displayed, if the measuring instrument provided on the column material is a surveying instrument, differential value information corresponding to items whose measurement directions of the surveying instrument are in all directions may be displayed as shown in Fig. 9.

[0125] By displaying the information in this manner, it is possible to present difference information for measurement items according to the user's needs, and to easily grasp the state of a specific managed object.

[0126] Moreover, the difference information (specifically, difference value information) is displayed in a different manner depending on the magnitude of the difference.

[0127] Specifically, as shown in Fig. 6, the magnitude of the difference value information is displayed differently depending on the magnitude of the difference (for example, the greater the magnitude of the difference, the larger the magnitude of the difference value information is displayed). However, without being limited to this, for example, the color of the difference value information may be displayed differently depending on the magnitude of the difference (for example, the greater the magnitude of the difference, the higher the saturation of the color of the difference value information is displayed), or a combination of these may be used.

[0128] By displaying the information in this manner, the details of the difference information can be visually and simply presented, making it easier to grasp the state of the managed object in more detail.

[0129] Furthermore, the measurement data and / or reference value information corresponding to the difference information is displayed in the vicinity of the difference information.

[0130] 6, measurement time information of the measurement data M included in the management information acquired by SB5 is displayed in the vicinity of the difference value information of the difference information D. However, without being limited to this, for example, measurement value information of the above measurement data, reference value information, or a combination of these may be displayed in the vicinity of the difference value information.

[0131] By displaying in this manner, the measurement data and / or reference value information can be presented in association with the difference information, making it easier to grasp the state of the managed object in more detail.

[0132] Returning to FIG. 4, in SB8, the terminal side control unit 25 of the terminal device 20 determines whether or not the timing to end the management process (hereinafter referred to as "second end timing") has arrived.

[0133] The method for determining whether or not this second end timing has arrived is arbitrary, but in the embodiment, the determination is made based on whether or not a specified operation has been accepted via the terminal side operation unit 21, and if the specified operation has been accepted, it is determined that the second end timing has arrived, and if the specified operation has not been accepted, it is determined that the second end timing has not arrived.

[0134] Then, if it is determined that the second end timing has arrived (SB8, Yes), the terminal side control unit 25 of the terminal device 20 ends the management process. On the other hand, if it is determined that the second end timing has not arrived (SB8, No), the terminal side control unit 25 proceeds to SB1, and thereafter similarly repeats the processes from SB1 to SB8.

[0135] Through the above-described management process, difference information and a display image can be provided to the user of the terminal device 20, enabling the user of the terminal device 20 to grasp the details of the state of the managed object. In particular, on the condition that the providing unit 12d has acquired authentication information from the terminal device 20, the providing unit 12d provides the terminal device 20 with difference information and a display image linked to the authentication information, and the terminal side display unit 23 displays the difference information and the display image provided by the providing unit 12d. This makes it possible to improve security when providing the difference information and the display image to the terminal device 20, and to improve usability of the management system 1.

[0136] (Effects of the embodiment) Thus, according to the embodiment, there is provided a calculation unit 12b that calculates the difference between the measurement data acquired by the acquisition unit 12a and a reference value acquired by a predetermined method, and a display means that displays, in correlation with each other, difference information indicating the difference calculated by the calculation unit 12b and a display image generated by the predetermined method and including a managed object image related to the managed object. This makes it possible to grasp the state of the managed object in detail and easily, thereby improving the manageability of the managed object.

[0137] Furthermore, since the display means displays a plurality of pieces of difference information with different time series in a switchable manner according to the time series, it is possible to present time-series difference information according to needs, and it is possible to easily grasp the state of a specific managed object.

[0138] Furthermore, since the display means displays a plurality of pieces of difference information with different measurement items in a switchable manner according to the measurement item, difference information for measurement items according to needs can be presented, and the state of a specific managed object can be easily grasped.

[0139] Furthermore, since the display means displays the difference information in different formats depending on the magnitude of the difference, the details of the difference information can be visually and easily presented, making it easier to grasp the state of the managed object in more detail.

[0140] In addition, since the display means displays information indicating the measurement data and / or reference value corresponding to the difference information in a position adjacent to the difference information, the measurement data and / or reference value information can be presented in association with the difference information, making it easier to grasp the state of the managed object in more detail.

[0141] Furthermore, since the display means displays the difference information in a position adjacent to the centerline of the managed image, the difference information can be presented in association with the centerline of the managed image, thereby improving the visibility of the difference information and the managed image.

[0142] The management system 1 further includes a linking unit 12c that links the difference information, the display image, and authentication information that enables the difference information and / or the display image to be provided, and a providing unit 12d that provides the terminal device 20 with the difference information and / or the display image linked to the authentication information, on the condition that the authentication information has been obtained from the terminal device 20.The terminal side display unit 23 displays the difference information and the display image provided by the providing unit 12d, thereby improving security when providing the difference information and the display image to the terminal device 20 and improving usability of the management system 1.

[0143] [III] Modifications to the embodiment Although the embodiments of the present invention have been described above, the specific configurations and means of the present invention can be modified and improved as desired within the scope of the technical ideas of the inventions described in the claims. Such modifications will be described below.

[0144] (About the problem to be solved and the effects of the invention) First, the problems that the invention aims to solve and the effects of the invention are not limited to those described above, and the present invention may solve problems that are not described above or achieve effects that are not described above, or may solve only some of the problems that are described or achieve only some of the effects that are described.

[0145] (Regarding decentralization and integration) In addition, each of the electrical components described above is functionally conceptual, and does not necessarily have to be physically configured as illustrated. In other words, the specific form of distribution or integration of each part is not limited to that shown in the figure, and all or part of them can be functionally or physically distributed or integrated in any unit according to various loads, usage conditions, etc. In addition, the "system" in this application is not limited to one configured by multiple devices, but includes one configured by a single device. In addition, the "device" in this application is not limited to one configured by a single device, but includes one configured by multiple devices. In addition, the data structure of each information described in the above embodiment may be changed arbitrarily. For example, the management device 10 may be distributed and configured into multiple devices configured to be able to communicate with each other, and the management side control unit 12 may be provided in some of these multiple devices, and the management side storage unit 13 may be provided in another part of these multiple devices.

[0146] (shape, number, structure, time series) The components illustrated in the embodiments and drawings may be modified and improved as desired within the scope of the technical concept of the present invention with respect to the shape, numerical values, or structure or chronological relationships of multiple components.

[0147] (Regarding managed objects) In the above embodiment, the object of management is described as an office building under construction, but the object of management is not limited to this and may be, for example, an office building after construction.

[0148] (About measuring instruments) In the above embodiment, the measuring instruments are described as surveying instruments, level gauges, and inclinometers, but are not limited thereto. For example, they may be strain gauges, pore water pressure gauges, anemometers, and settlement gauges (such as a serial stratification settlement gauge, for example). Alternatively, if the object of management is an industrial product, they may be thermometers, ammeters, voltmeters, etc. Alternatively, if the object of management is a patient or animal under medical care, they may be pulse meters, blood pressure monitors, etc.

[0149] (About the management system) In the above embodiment, the management system 1 is described as including the management device 10 and the terminal device 20, but is not limited thereto. For example, when the management device 10 is a stationary management server installed in a management building, and the management device 10 is provided with a display means, the providing unit 12d of the management device 10 and the terminal device 20 may be omitted.

[0150] (Display method) In the above embodiment, the display means is described as the terminal side display unit 23, but is not limited to this. For example, it may be the display means of the management side terminal device. Alternatively, if the management device 10 is a stationary management server installed in a management building, it may be the display means of the management device 10.

[0151] (Regarding management processing) In the above embodiment, the terminal display unit 23 in SB7 displays a plurality of pieces of difference information in a switchable manner according to the time series and the measurement item, but this is not limited to this. For example, it is not necessary to be able to display a plurality of pieces of difference information in a switchable manner according to at least one of the time series and the measurement item.

[0152] In addition, in the above embodiment, it has been explained that in SB7, the terminal side display unit 23 can display information indicating measurement data and / or reference values ​​corresponding to the difference information in a position adjacent to the difference information. However, this is not limited to this, and for example, it is not necessary to be able to display information indicating the measurement data and reference values ​​in a position adjacent to the difference information.

[0153] In addition, in the above embodiment, it was explained that when the managed object is a construction component, the terminal side display unit 23 in SB7 displays difference information at a position near the center line of the managed object image. However, this is not limited to this, and for example, the difference information may be displayed at a position other than the position near the center line of the managed object image.

[0154] In addition, in the above embodiment, it has been described that the providing unit 12d provides the terminal device 20 with difference information and a display image linked to the authentication information on the condition that the authentication information is acquired from the terminal device 20, but this is not limited to the above.

[0155] For example, the providing unit 12d may provide only either the difference information or the display image to the terminal device 20 on the condition that authentication information has been acquired from the terminal device 20. As an example, when the management subject identification information corresponding to the difference information to be transmitted matches the management subject identification information corresponding to the difference information previously provided, the providing unit 12d may transmit the management information including the difference information to be transmitted but without including the display image. Furthermore, when an error exists in the display image previously transmitted, the providing unit 12d may transmit the management information including only the corrected display image. Alternatively, when the providing unit 12d generates a display image at any time according to the construction progress of the structure, the providing unit 12d may transmit the management information including only the generated display image.

[0156] Alternatively, the providing unit 12d may provide the difference information and the display image to the terminal device 20 without the condition that authentication information has been acquired from the terminal device 20. As an example, the generation of authentication information may be omitted, and after the difference information and the display image are linked by the linking unit 12c, the linked difference information and the display image may be automatically provided (transmitted) to the terminal device 20. In this case, SA6, SA8, SA9, and SB1-SB4 of the management process may be omitted.

[0157] Alternatively, when the difference information linked to the authentication information is further subdivided and linked by type of measurement item (for example, earth retaining displacement, column displacement, floor displacement, etc.), measurement type information indicating a specific type of measurement item may be included in the authentication information, and when the providing unit 12d acquires the authentication information from the terminal device 20, the providing unit 12d may provide only the difference information that matches the type of measurement item in the measurement type information included in the authentication information to the terminal device 20. Also, when the display image linked to the authentication information is further subdivided and linked by type of image (for example, underground structure, upper structure, etc.), image type information indicating a specific type of image may be included in the authentication information, and when the providing unit 12d acquires the authentication information from the terminal device 20, the providing unit 12d may provide the terminal device 20 with a display image that matches the image type in the image type information included in the authentication information.

[0158] (About the displayed images) In the above embodiment, the display image is described as a three-dimensional image, but this is not limited to this. Fig. 10 is a diagram showing a modified example of Fig. 9. For example, as shown in Fig. 10, the display image may be a two-dimensional image.

[0159] In the above embodiment, the display image is described as a BIM model image, but is not limited to this. For example, when managing construction members constituting an existing structure as objects to be managed, the display image may be an image captured by a known imaging means (or an image obtained by processing the captured image).
