Description

[Technical Field]

[0001] The present invention relates to a construction management system, a construction management method, and a construction management program for a prime contractor to manage the construction status in pile construction work and the like. [Background technology]

[0002] Traditionally, inspections have been conducted in construction projects for construction management purposes. During these inspections, a prime contractor's staff member may be present along with subcontractors working at the construction site. In this case, the prime contractor's staff member photographs the inspection status and keeps a record of it. The photographs are taken together with a blackboard listing the inspection target, inspection results, and other information. Therefore, technologies for keeping records of the inspection status have been considered (see, for example, Patent Document 1). The construction management system described in Patent Document 1 registers construction management standards that define the inspection items and criteria for each individual construction project that are standard for each building project. This management system then creates construction site construction management standards for construction projects based on key management items, records the results of checks performed based on the inspection items for each individual construction project, and creates and outputs an inspection report of the inspection results.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 11-7473 Summary of the Invention [Problem to be solved by the invention]

[0004] However, if the prime contractor's person in charge is not present at the construction site where the on-site inspection is to be conducted, the workers at the construction site will call the person in charge and conduct the on-site inspection after the person in charge arrives. In this case, construction work will be suspended until the person in charge arrives at the construction site. [Means for solving the problem]

[0005] A construction management system that solves the above problem is a construction management system that has a management server that is connected via a network to a terminal viewed by a first person and a camera attached to a second person, has an inspection information storage unit that records inspection images, and manages the construction status, where the management server displays sequential images acquired by the camera at the inspection site on the terminal, acquires inspection images generated from the sequential images in response to shooting instructions entered by the first person, identifies the components to be inspected based on the information acquired from the camera, associates the inspection images with blackboard information for the identified components, and records the inspection images in the inspection information storage unit. Here, sequential images refer to images that display the camera's shooting range on the terminal in real time, and are multiple still images that are used to specify the still images that will be recorded as the inspection images. [Effects of the Invention]

[0006] According to the present invention, inspection images can be recorded efficiently. [Brief explanation of the drawings]

[0008] An embodiment of a construction management system, a construction management method, and a construction management program will be described below with reference to Figures 1 to 8. In this embodiment, a construction management system will be described that remotely manages the construction status of inspections that are normally conducted by the prime contractor in pile construction work. As shown in FIG. 1, the construction management system uses a subcontractor camera 10, a prime contractor camera 15, a management server 20, a prime contractor terminal 30, a marker device A1, and a beacon B1.

[0009] (Example of hardware configuration) FIG. 2 shows an example of the hardware configuration of an information processing device H10 that functions as a subcontractor camera 10, a prime contractor camera 15, a management server 20, a prime contractor terminal 30, and the like.

[0010] The information processing device H10 includes a communication device H11, an input device H12, a display device H13, a storage device H14, and a processor H15. Note that this hardware configuration is an example, and the information processing device H10 may include other hardware.

[0011] The communication device H11 is an interface that establishes a communication path with another device and executes data transmission and reception, and is, for example, a network interface or a wireless interface.

[0012] The input device H12 is a device that accepts input from a user, etc., and is, for example, a mouse, a keyboard, an operation button, a touch panel, etc. The display device H13 is a display or a touch panel display that displays various information.

[0013] The storage device H14 is a storage device that stores data and various programs for executing various functions of the subcontractor camera 10, the prime contractor camera 15, the management server 20, the prime contractor terminal 30, etc. Examples of this storage device include the building information storage unit 22, the pile driver information storage unit 23, the equipment information storage unit 24, and the inspection information storage unit 25, which will be described later. Examples of the storage device H14 include ROM, RAM, and a hard disk.

[0014] The processor H15 uses the programs and data stored in the storage device H14 to control each process (for example, the process in the control unit 21, which will be described later) in the subcontractor camera 10, the prime contractor camera 15, the management server 20, and the prime contractor terminal 30. Examples of the processor H15 include a CPU and an MPU. The processor H15 loads programs stored in a ROM or the like into a RAM and executes various processes corresponding to the various processes. For example, when an application program in the subcontractor camera 10, the prime contractor camera 15, the management server 20, or the prime contractor terminal 30 is launched, the processor H15 runs a process that executes each process, which will be described later.

[0015] The processor H15 is not limited to a processor that performs all of its processing using software. For example, the processor H15 may include a dedicated hardware circuit (e.g., an application-specific integrated circuit (ASIC)) that performs hardware processing for at least some of the processing it performs. That is, the processor H15 may be configured with the following:

[0016] [1] One or more processors that operate according to a computer program (software). [2] One or more dedicated hardware circuits that perform at least some of the various processes.

[0017] [3] A circuit that includes a combination of these. The processor includes a CPU and memory, such as RAM and ROM, that stores program code or instructions configured to cause the CPU to perform processes. Memory, or computer-readable media, includes any available media that can be accessed by a general-purpose or special-purpose computer.

[0018] (Construction management system functions) Next, the functions of the management server 20, prime contractor terminal 30, subcontractor camera 10, prime contractor camera 15, marker device A1, and beacon B1 as a construction management system will be described with reference to FIG.

[0019] The subcontractor's camera 10 is a camera used by the subcontractor's worker (second person in charge) working at the construction site, and takes pictures to check the work. The subcontractor's camera 10 is a second camera and stores a unique camera ID.

[0020] The prime contractor's camera 15 is a camera used by the prime contractor's person in charge (first person in charge). This prime contractor's camera 15 is used to capture images for confirming inspections attended by the prime contractor. The prime contractor's camera 15 is a body camera attached to a worker, and is installed in a position on the worker's body that does not interfere with the helmet or work. The prime contractor's camera 15 stores a unique camera ID. The prime contractor's camera 15 also acquires beacon signals from beacons B1 installed on construction machinery (heavy machinery) at the construction site. Furthermore, the prime contractor's camera 15 transmits and receives data to and from the subcontractor's camera 10 using short-range communication such as Bluetooth (registered trademark).

[0021] As shown in Figure 8, beacon B1 is installed near the drilling head of pile driver 11b. This beacon B1 outputs a beacon signal that can be received within range C1. In this case, when the worker who attached prime contractor's camera 15 is at position B2, prime contractor's camera 15 receives the beacon signal. This beacon signal includes a beacon ID.

[0022] Furthermore, a plurality of marker devices A1 are provided spaced apart on the pile driver 11b. Specifically, a GNSS (Global Navigation Satellite System) receiver is used as the marker device A1.

[0023] The management server 20 in Fig. 1 is a computer system that manages the construction status. The management server 20 is connected via a network to the prime contractor's camera 15 and the prime contractor's terminal 30. Furthermore, the management server 20 acquires information specifying the position (longitude and latitude) of each of the multiple marker devices A1.

[0024] The management server 20 includes a control unit 21 , a building information storage unit 22 , a pile driver information storage unit 23 , an equipment information storage unit 24 , and an inspection information storage unit 25 . The control unit 21 performs the processes described below (processes including a camera management stage, a blackboard information generation stage, an image recording stage, etc.). By executing a construction management program for this purpose, the control unit 21 functions as a camera management unit 211, a blackboard information generation unit 212, and an image recording unit 213.

[0025] The camera management unit 211 executes management processing for the operation of the prime contractor's camera 15. In this embodiment, the camera management unit 211 executes processing for starting and stopping the prime contractor's camera 15 and acquiring images from the prime contractor's camera 15.

[0026] The blackboard information generating unit 212 executes a process of generating blackboard information to be stored in association with the inspection image. The image recording unit 213 stores the inspection image in the inspection information storage unit 25 in association with the blackboard information.

[0027] 3, the building information storage unit 22 stores component management data 220 for managing each component that constitutes a building. The component management data 220 is recorded when a building is designed. The component management data 220 includes data related to component IDs, component types, component locations, and component attribute information.

[0028] The member ID data area stores data related to an identifier that identifies each member. For example, in the case of a pile, the pile number is used as the member identifier. The member type data area stores data specifying the type of member, such as a pillar, beam, or pile.

[0029] The position data area of the member stores data on the position where the member is to be placed. Since the position of the stake hole coincides with the position of the stake to be placed in the stake hole, the position of the member in the stake is used as the position of the stake hole. The attribute information data area of a component stores data on the attributes of the component. For example, if the component is a stake, data on the shape and size of the stake is included.

[0030] 4, pile driver information storage unit 23 stores pile driver management data 230 for managing pile drivers (earth augers) 11b used in pile construction. The pile driver management data 230 is recorded when a pile driver 11b is placed at a construction site. The pile driver management data 230 includes data related to a pile driver ID, a beacon ID, a marker device ID, and a pile position calculation formula.

[0031] The pile driver ID data area stores data relating to an identifier that identifies each pile driver 11b. The beacon ID data area records data relating to an identifier that identifies the beacon B1 attached to this pile driver 11b. The marker device ID data area stores data relating to identifiers that identify the plurality of marker devices A1 attached to the pile driver 11b at intervals.

[0032] The pile position calculation formula data area stores a function for identifying the position of the excavation head of the pile driver 11b using the position coordinates of multiple marker devices A1 mounted on the pile driver 11b. Here, since pile holes are formed by the excavation head, it is assumed that the position of the excavation head, the positions of the pile holes, and the piles are the same. In this embodiment, as the pile position calculation formula data, an arithmetic expression is used that identifies the position (distance and direction) of the excavation head based on the positional relationship using multiple marker devices A1.

[0033] As shown in Fig. 5, the equipment information storage unit 24 records equipment management data 240 related to equipment such as cameras used at the site. The equipment management data 240 is recorded when equipment used at the site is registered. The equipment management data 240 includes data related to the construction site ID, prime contractor ID, prime contractor camera ID, prime contractor terminal ID, and prime contractor contact information.

[0034] The construction site ID data area records data relating to an identifier for identifying this site. The prime contractor ID data area, prime contractor camera ID data area, and prime contractor terminal ID data area record data regarding identifiers for respectively identifying the prime contractor at this site, the prime contractor camera 15 used by the prime contractor, and the prime contractor terminal 30.

[0035] The prime contractor contact data area records data related to the prime contractor's contact information, including the contractor's mobile phone number, email address, etc.

[0036] As shown in FIG. 6, the inspection information storage unit 25 stores inspection information data 250 for managing inspection information. The inspection information data 250 is recorded when a still image is generated. The inspection information data 250 includes data related to the still image and blackboard information. The blackboard information is information that was written on a blackboard captured in a conventional pile construction inspection photo, and includes, for example, the target pile and the name of the construction work. The blackboard information in this embodiment includes at least information that identifies the target pile of the associated still image that is stored. Specifically, the data related to the blackboard information includes data related to the construction site ID, the target pile ID, the construction machine, the date and time of the photo, and the inspection results.

[0037] The still image data area records data on each still image taken by the prime contractor's camera 15. This still image is generated from a series of images taken by the prime contractor's camera 15 and displayed on the prime contractor's terminal 30, in response to a shooting instruction from the person in charge.

[0038] The construction site ID data area stores data relating to an identifier that identifies the construction site of the pile work where the image was taken. In the processing target pile ID data area, data on an identifier (member ID) that identifies the processing target pile associated with the inspection image is recorded.

[0039] In the construction machine data area, data relating to an identifier (pile driver ID) that identifies the pile driver 11b used to bury the target pile is recorded. The photographing date and time data area records data relating to the date and time when the image was photographed.

[0040] The inspection result data area records data on the inspection results for the items of the witness inspection conducted using this image. The inspection results include the camera ID of the subcontractor's camera 10, the camera ID of the prime contractor's camera 15, and the prime contractor's terminal ID. The camera ID of the subcontractor's camera 10, the camera ID of the prime contractor's camera 15, and the prime contractor's terminal ID can be used to identify the subcontractor's workers and the prime contractor's personnel.

[0041] The prime contractor terminal 30 shown in Figure 1 is a computer terminal used by a prime contractor's staff member who is not on-site. This prime contractor terminal 30 stores a unique prime contractor terminal ID. Furthermore, the prime contractor terminal 30 stores on-site inspection items to be included in the inspection results on the blackboard information. These on-site inspection items include, for example, confirmation of the drilling head diameter, confirmation of the drilling core position, confirmation of the verticality when driving piles, and confirmation of the pile head level.

[0042] (Construction status management processing) Next, the construction status management process will be described with reference to FIGS. First, at the site, the worker turns on the subcontractor's camera 10 and the prime contractor's camera 15. Then, the worker calls the prime contractor's person in charge who will be present at the site to request their presence.

[0043] Thereafter, the prime contractor terminal 30 executes the attendance start process (step S11). Specifically, in response to an instruction from the prime contractor's person in charge, the prime contractor terminal 30 transmits an attendance start instruction to the management server 20. This attendance start instruction includes the prime contractor terminal ID of the prime contractor terminal 30 and the construction site ID where attendance will be performed.

[0044] The control unit 21 of the management server 20 executes a process of instructing the start of filming (step S12). Specifically, the camera management unit 211 of the control unit 21 identifies the prime contractor camera ID included in the equipment management data 240 in which the received prime contractor terminal ID and construction site ID are recorded. In this case, the blackboard information generation unit 212 of the control unit 21 temporarily stores the prime contractor terminal ID, construction site ID, and prime contractor camera ID. Then, it sends an instruction to start filming to the prime contractor camera 15 associated with this prime contractor camera ID.

[0045] Upon receiving the instruction to start shooting, the prime contractor's camera 15 executes a process to check whether the subcontractor's camera is activated (step S13). Specifically, the prime contractor's camera 15 communicates with the subcontractor's camera 10, and if the subcontractor's camera 10 is activated, acquires the unique camera ID of the subcontractor's camera 10.

[0046] Then, when the camera ID of the subcontractor camera 10 is acquired, the prime contractor camera 15 executes a process of transmitting the beacon ID (step S14). Specifically, if the prime contractor camera 15 continues to receive a beacon signal, it temporarily stores the beacon ID and transmits it to the management server 20. In this case, the prime contractor camera 15 transmits the acquired camera ID of the subcontractor camera 10 together with the beacon ID. Note that if the prime contractor camera 15 cannot receive a beacon signal, it stops transmitting the beacon ID and transmits the beacon ID after receiving the beacon signal.

[0047] Upon receiving the beacon ID, the control unit 21 of the management server 20 executes a process for identifying the target pile and pile driver (step S15). Specifically, the blackboard information generation unit 212 of the control unit 21 temporarily stores the received beacon ID and the camera ID of the subcontractor camera 10. Furthermore, the blackboard information generation unit 212 identifies the pile driver management data 230 including this beacon ID in the pile driver information storage unit 23. Next, the blackboard information generation unit 212 identifies the pile driver ID and the marker device ID in the identified pile driver management data 230. Then, the blackboard information generation unit 212 acquires position (longitude and latitude) information of each marker device A1 from the marker device A1 with the identified marker device ID. Furthermore, the blackboard information generation unit 212 acquires the position (center) of the excavation head using the acquired positions of the marker devices A1 and the pile position calculation formula in the pile driver management data 230. Then, the blackboard information generating unit 212 identifies, from the component management data 220 of the component type (pile), components (pile) located within the allowable radius from the identified position of the excavation head. Specifically, as shown in FIG. 8, the member management data 220 of the pile P1 that is within the allowable range C2 is identified.

[0048] Then, the prime contractor terminal 30 executes a display process of the pile hole and the pile driver to be processed (step S16). Specifically, the prime contractor terminal 30 displays the component ID of the pile P1, which is the identified pile to be processed, and the pile driver ID of the pile driver management data 230 for this pile P1, on the display device H13 of the prime contractor terminal 30.

[0049] The prime contractor's camera 15 executes video recording processing (step S17). Specifically, the prime contractor's camera 15 associates the captured video (continuous images) with a camera ID and transmits it to the management server 20. If the prime contractor's camera 15 is no longer able to receive a beacon ID, it stops recording video until it receives the temporarily stored beacon ID. If the prime contractor's camera 15 acquires a beacon ID different from the temporarily stored beacon ID, it executes the processing from step S14 onwards.

[0050] The control unit 21 of the management server 20 that has received the video executes a transfer process for the video (step S18). Specifically, the image recording unit 213 of the control unit 21 transmits the video acquired from the prime contractor's camera 15 to the prime contractor's terminal 30.

[0051] Then, the prime contractor terminal 30 executes a process for displaying the moving image (step S19). Specifically, the image recording unit 213 of the control unit 21 displays the moving image acquired from the management server 20 on the screen of the display device H13.

[0052] Next, the prime contractor terminal 30 executes a process of determining whether or not a photographing instruction has been acquired (step S20). Specifically, the prime contractor terminal 30 acquires a photographing instruction by pressing the photographing button on the screen.

[0053] Here, if a shooting instruction is acquired ("YES" in step S20), the prime contractor terminal 30 executes the recording instruction process (step S21). Specifically, the prime contractor terminal 30 generates a still image from the video. Then, the prime contractor terminal 30 displays a confirmation screen including the still image, an inspection item selection field, and a registration button. Here, the person in charge selects the inspection details of the witnessed inspection of the captured image on the confirmation screen and presses the registration button. As a result, the prime contractor terminal 30 associates the shooting date and time when the still image was generated, the inspection details, and the still image, and sends them to the management server 20.

[0054] The control unit 21 of the management server 20 executes a process for generating blackboard information (step S22). Specifically, the blackboard information generation unit 212 of the control unit 21 generates inspection information data 250 including still images and blackboard information. Here, the blackboard information generation unit 212 includes the photographing date and time, construction site ID, component ID, pile driver ID, and inspection results. Furthermore, the inspection results include the received inspection details, the temporarily stored subcontractor camera ID, prime contractor camera ID, and prime contractor terminal ID.

[0055] Next, the control unit 21 of the management server 20 executes a recording process of the examination information (step S23). Specifically, the image recording unit 213 of the control unit 21 stores the generated examination information data 250 in the examination information storage unit 25.

[0056] On the other hand, if a shooting instruction is not acquired ("NO" in step S20), the recording instruction process is skipped. Thereafter, the prime contractor terminal 30 executes a process for determining whether or not the process is to be ended (step S24). Specifically, if an end instruction is input to the prime contractor terminal 30, the process is determined to be ended.

[0057] If the end instruction is not acquired ("NO" in step S24), the process from the video display process (step S19) onwards is executed. On the other hand, if it is determined that the process should be terminated (YES in step S24), the prime contractor terminal 30 executes the termination instruction process (step S25). Specifically, the prime contractor terminal 30 transmits the termination instruction to the management server 20.

[0058] The control unit 21 of the management server 20 executes the transfer process of the end instruction (step S26). Specifically, the camera management unit 211 of the control unit 21 sends a signal to stop shooting to the prime contractor's camera 15. In response to this, the prime contractor's camera 15 executes the stop of shooting (step S27). Specifically, the prime contractor's camera 15 stops shooting. Thereafter, the worker turns off the power to the subcontractor's camera 10 that he is using, and also turns off the power to the prime contractor's camera 15.

[0059] According to this embodiment, the following effects can be obtained. (1) In this embodiment, successive images taken by the prime contractor's camera 15 photographing the site are displayed on the prime contractor's terminal 30. The prime contractor's personnel can use the successive images displayed on the prime contractor's terminal 30 to check the construction status at the site, and can also save still images taken in response to photography instructions as inspection images.

[0060] (2) In this embodiment, if the prime contractor's camera 15 does not receive a signal from the beacon B1 installed on the pile driver 11b, it stops processing until it receives a signal. As a result, if the worker who attached the prime contractor's camera 15 moves to a position far from the beacon B1, the worker will not transmit images. Therefore, images can be transmitted to the prime contractor's terminal 30 only when the worker is in a location where an on-site inspection is to be conducted near the pile driver.

[0061] (3) In this embodiment, the management server 20 associates the blackboard information, including information about the pile to be processed and the pile driver, with the still image and executes the inspection information recording process (step S23). This allows the information about the pile to be processed and the pile driver to be associated with the still image and stored in the inspection information storage unit 25.

[0062] (4) In this embodiment, the management server 20 acquires the still images generated by the prime contractor terminal 30 together with the photographing date and time and the inspection results of the witnessed inspection items, and stores them in the inspection information data 250. This allows the inspection results and the photographing date and time to be associated with the still images and saved.

[0063] (5) In this embodiment, the management server 20 associates the subcontractor camera ID of the subcontractor camera 10 and the prime contractor camera ID of the prime contractor camera 15, which are acquired together with the beacon ID, with the still image, and executes the inspection information recording process (step S23). This allows information about the subcontractor and the prime contractor to be associated with the still image and stored in the inspection information storage unit 25.

[0064] This embodiment can be modified as follows: This embodiment and the following modifications can be combined and implemented within the scope of technical compatibility. In the above embodiment, the worker activates the prime contractor's camera 15 when activating the subcontractor's camera 10. The prime contractor's camera 15 does not necessarily have to be activated by the worker. For example, the subcontractor's camera and the prime contractor's camera may communicate with each other, and the prime contractor's camera may be activated in conjunction with the activation of the subcontractor's camera. Specifically, when the subcontractor's camera 10 is turned on, the subcontractor's camera 10 communicates with the prime contractor's camera 15 and powers on the prime contractor's camera 15. When the prime contractor's camera 15 is powered on, the prime contractor's camera 15 sends a request for attendance to the management server 20. This attendance request includes the prime contractor's camera 15's unique camera ID. The control unit 21 of the management server 20 identifies, in the device information storage unit 24, the device management data 240 that has the prime contractor's camera ID as the camera ID of the attendance request. The control unit 21 then sends an attendance request email to the email address included in the prime contractor's contact information in the device management data 240. Alternatively, the control unit 21 can call the mobile phone number of the prime contractor's contact point, which activates the prime contractor's camera 15 in conjunction with the power-on of the subcontractor's camera 10, and also allows the management server to contact the prime contractor to request their attendance. In addition, the management server 20 may directly communicate with the subcontractor camera 10 to obtain information such as the activation of the subcontractor camera 10.

[0065] In the above embodiment, the management server 20 stores the inspection details acquired via the inspection item selection field as blackboard information during the recording instruction process (step S20). Acquisition of the inspection details is not limited to selection by the person in charge in the inspection item selection field. For example, the inspection details may be identified by performing known image recognition on the generated still image (inspection image). In this case, the control unit 21 of the management server 20 stores the pattern of the still image expected to be acquired for each inspection item. The control unit 21 may then perform pattern matching for each stored inspection item to identify the inspection item corresponding to the generated still image. For example, when confirming the position of the drilling core, the image is often taken in a state in which a measuring device such as a tape measure is positioned horizontally in two axial directions relative to the drilling head. Therefore, the inspection items for the generated still image may be identified by comparing such an image with the still image.

[0066] In the above embodiment, the control unit 21 of the management server 20 identifies the pile to be processed according to the beacon ID received from the prime contractor's camera 15. The information acquired from the prime contractor's camera 15 to identify the pile to be processed is not limited to the beacon ID; for example, the prime contractor's camera 15 may be provided with a GNSS function to acquire the position of the prime contractor's camera 15. Furthermore, instead of the beacon signal of the beacon B1, the prime contractor's camera 15 may transmit information acquired using proximity communication such as Wi-Fi (registered trademark) installed in the pile driver 11b to identify the pile to be processed.

[0067] In the above embodiment, coordinate information (latitude and longitude) of the position of the marker device A1 installed on the pile driver 11b was acquired. However, as long as the device can acquire information for identifying the pile to be processed, the location information is not limited to being acquired directly from the marker device A1. For example, the prime contractor's camera may be equipped with a GNSS function. The management server 20 may acquire the location information of the prime contractor's camera 15 from the prime contractor's camera 15 and identify the pile to be processed based on this location information. In the above embodiment, the control unit 21 of the management server 20 identifies the pile driver 11b based on the beacon ID received from the prime contractor's camera 15 and identifies the target pile based on the position of the marker device A1 installed on the pile driver 11b. In this case, if multiple piles can be identified as targets for processing based on the position of the marker device A1, these piles may be included in the blackboard information as candidates for target piles. Then, by comparing the shooting time recorded in the inspection information with the construction status of each pile, the target pile whose inspection item content matches the construction status is identified from the candidate target piles and saved as the target pile in the blackboard information by overwriting it. Normally, for safety reasons, construction of adjacent piles is not carried out simultaneously, so the target pile can be identified using the shooting time.

[0068] Furthermore, the information that the control unit 21 of the management server 20 receives from the prime contractor's camera 15 is not limited to the beacon ID, but may be any information that can identify the target pile of the blackboard information to be associated with the inspection image. For example, instead of the beacon ID, the prime contractor's camera 15 may identify the blackboard information of the target pile based on information acquired from an RFID (Radio Frequency Identification) tag or a two-dimensional code, such as an IC tag, attached to the pile driver 11b. In this case, the RFID or two-dimensional code may directly store information identifying the target pile and the blackboard information, or information identifying the pile driver may be stored, and the target pile may be identified using the pile driver management data 230, as in the above embodiment. Furthermore, before taking the video, the prime contractor's camera 15 may take an image containing information identifying the pile to be treated. Then, the control unit 21 of the management server 20 performs image recognition on the image acquired from the prime contractor's camera 15 to identify the information contained in the image that identifies the pile to be treated, and identifies the pile to be treated from this information. After identifying the pile to be treated using the image, the control unit 21 stores the blackboard information of the identified pile to be treated in association with the still image acquired from the prime contractor's terminal 30 in the recording instruction process (step S21).

[0069] In the above embodiment, the control unit 21 of the management server 20 stores blackboard information including inspection results in association with still images in the inspection information storage unit 25. The inspection results include the details of the inspection items, the subcontractor's camera ID, the prime contractor's camera ID, and the prime contractor's terminal ID. The blackboard information and the contents of the inspection results included therein are not limited to this. For example, the control unit 21 of the management server 20 may record the name of the subcontractor corresponding to the subcontractor's camera ID, the name of the prime contractor corresponding to the prime contractor's camera ID, and the name of the prime contractor's staff member corresponding to the prime contractor's terminal ID in the blackboard information. Specifically, the management server 20 pre-stores subcontractor information data that stores the name of the subcontractor and the name of the subcontractor's worker corresponding to the subcontractor's camera ID, and prime contractor information data that stores the name of the prime contractor corresponding to the prime contractor's camera ID and the name of the staff member corresponding to the prime contractor's terminal ID. Then, when the control unit 21 of the management server 20 acquires the subcontractor's camera ID, it uses the subcontractor information data to identify the name of the subcontractor and the name of the subcontractor's staff member. When the control unit 21 acquires the prime contractor camera ID, it identifies the name of the prime contractor using the prime contractor information data, and when it acquires the prime contractor terminal ID, it identifies the name of the person in charge using the prime contractor information data.The control unit 21 then includes the identified names of the subcontractors, the names of the subcontractors' workers, the name of the prime contractor, and the name of the person in charge in the blackboard information.

[0070] In the above embodiment, the construction machine is described as a pile driver 11b that forms pile holes and buries piles. However, the construction machine is not limited to the pile driver 11b and may be any construction machine that is used at a construction site.

(a) The construction management system according to claim 1, characterized in that the camera is capable of taking photographs when it receives a signal from a beacon terminal installed at the inspection location. (b) The construction management system according to claim 1 or (a), characterized in that the camera stops transmitting the continuous images to the terminal when it does not receive a signal from the beacon terminal installed at the inspection location.

[0072] (c) The construction management system described in (a) or (b) is characterized in that the management server obtains second camera identification information that identifies the second camera from a second camera used by the second person other than the camera, and includes the information in the blackboard information. (d) The construction management system described in (a), (b) or (c) is characterized in that the management server obtains second camera identification information that identifies the second camera from the second camera, identifies information about the second person in charge based on this second camera identification information, and includes it in the blackboard information.
