Description

The present invention relates to an inspection support system and an inspection support method that support inspection of joints used for bar arrangement.

Reinforcement mechanical joints have different degrees of joint reliability depending on the level of inspection (see, for example, Non-Patent Document 1). As described in this document, when a supervisor conducts a 100% inspection, reliability level I is specified. In addition, when a supervisor performs a sampling inspection of 20 or more locations with a sampling rate of 10% or more, the reliability is defined as type II.

The design value of the tensile yield strength (static strength, seismic performance, etc.) of the joint reinforcement differs depending on the type of reliability corresponding to the inspection level. In reliability class I, there is no reduction in the static yield strength of the tensile yield strength, and there is no reduction in the design value (high stress cyclic performance) of the tensile yield strength in the SA class joint. On the other hand, in the reliability type II, when the joint concentration is 1/2 or less (staggered arrangement) in the static proof stress, it is reduced to 0.9 times and checked, and the joint concentration is reduced to 1/2. If there are more (joints), reduce to 0.8 times and check. Furthermore, in this reliability type II, the design value of tensile yield strength (high stress repetition performance) is reduced to 0.9 times in the case of staggered arrangement even for SA class joints. In the case of splicing, it is stipulated that verification by experiment, analysis, etc. is necessary.

This item input screen includes a joint identifier of the selected joint 15, an input field for construction information, and a photography start button. Furthermore, this item input screen is provided with entry fields for each item such as construction date, builder, propriety of torque, propriety of fitting length, propriety of overflow, and the like.

Then, the work terminal 30 executes processing for transmitting construction item information (step S2-3). Specifically, when the input to each item input column is completed and the confirmation button is selected, the work terminal 30 associates each input item information with the joint identifier of this joint 15, and the inspection support server 20.

After acquiring the construction information, the control unit 21 of the inspection support server 20 executes a process of registering the construction item information (step S2-4). Specifically, the construction information registration unit 212 of the control unit 21 records the received construction item information in the joint management information 260 in which the received joint identifier is recorded.

On the other hand, the work terminal 30 writes the construction item information to the RFID tag (step S2-5). Specifically, the work terminal 30 uses the reader/writer 18 to write the acquired construction item information to the memory of the nearest RFID tag 16 from which the joint identifier has been acquired.

Next, the process of registering construction images will be described with reference to FIG.
The work terminal 30 selects the shooting start button on the initial screen displayed on the touch panel display. In addition, when photographing is performed separately from the registration process of construction item information, step S2-1 is executed again.

By selecting the shooting start button on the initial screen, the work terminal 30 executes shooting start processing (step S3-1). Specifically, the captured image captured by the camera unit is displayed on the display.

Then, the work terminal 30 executes processing for requesting a blackboard image to be inserted (step S3-2). The work terminal 30 transmits a blackboard image request to the inspection support server 20 . Here, the blackboard image request includes the specified joint identifier.

Next, the control unit 21 of the examination support server 20 executes blackboard image generation processing (step S3-3). Specifically, the construction information registration unit 212 of the control unit 21 acquires the joint information 252 including the received joint identifier from the CIM information storage unit 25, and acquires the reinforcing bar information 251 of the reinforcing bar connected to this joint. . Furthermore, the construction information registration unit 212 acquires the joint management information 260 including the joint identifier from the joint management information storage unit 26 .

Next, the construction information registration unit 212 generates a blackboard image by including blackboard description items in the blackboard template. Here, items written on the blackboard include the joint identifier, the reinforcing bar type of the acquired reinforcing bar information 251, and whether or not the torque and fitting length of the construction information of the joint management information 260 are acceptable.
Then, the control unit 21 of the inspection support server 20 transmits the blackboard image to the work terminal 30 .

The work terminal 30 executes superimposition processing of the blackboard image (step S3-4). Specifically, the work terminal 30 superimposes the blackboard image acquired from the examination support server 20 on the captured image displayed on the display.

For example, as shown in FIG. 7, a blackboard image 105 is displayed in the captured image 100 . This blackboard image 105 includes blackboard entries in a blackboard template. Items to be written on the blackboard include a joint identifier, a reinforcing bar type of a reinforcing bar to which the joint is connected, whether or not the joint can be fitted, and the like. Also, when a plurality of joints are included in the photographed image, the target joint may be specified using the pointer 107 .

Specifically, when the shooting button is selected on the work terminal 30, a construction image is generated in which the blackboard image 105 is superimposed (inserted). The work terminal 30 then transmits the construction image associated with the joint identifier to the inspection support server 20 .

Next, the control unit 21 of the inspection support server 20 executes a construction image registration process (step S3-6). Specifically, the construction information registration unit 212 of the control unit 21 records the construction image in the joint management information 260 in which the joint identifier is recorded.

(Inspection processing)
Next, the inspection process performed by the supervisor will be described with reference to FIG. This inspection process may be performed at the construction site or at a location other than the construction site.

First, with reference to FIG. 6A, the inspection process performed at the construction site will be described.
When the inspection execution program is started in the inspection terminal 40, the inspection terminal 40 executes the process of displaying the inspection execution screen (step S4-1). This inspection execution screen includes an RFID tag 16 reading instruction button, an inspection range input field, and a construction information request button.

When the reading instruction button is selected on the inspection execution screen, the inspection terminal 40 executes processing for acquiring information from the RFID tag (step S4-2). Specifically, the inspection terminal 40 activates the read program and acquires information stored in the memory of the nearest RFID tag 16 via the reader 19 . This information includes the joint identifier of the joint 15 to which the RFID tag 16 is attached, and the reinforcing bar type and construction item information of the reinforcing bar information 251 .

Then, the inspection terminal 40 displays an inspection screen on the touch panel display. This inspection screen includes an information display column displaying the reinforcing bar type and construction item information read from the memory of the RFID tag 16, and an inspection result entry column for entering inspection items.

Next, the inspection terminal 40 executes inspection result information transmission processing (step S4-3). Specifically, the supervisor checks the reinforcing bar type and construction item information displayed in the information display column of the inspection screen, and the status of the joints at the site. Then, if there is no problem in all inspection items, the supervisor enters the inspection date and name in the inspection result entry column.
Then, when the save button is selected, the inspection terminal 40 associates the inspection result information input on the inspection screen with the joint identifier and transmits the information to the inspection support server 20 .

Next, the control unit 21 of the examination support server 20 executes examination result information registration processing (step S4-4). Specifically, the inspection management unit 213 of the control unit 21 additionally records the acquired inspection result in the joint management information 260 including the joint identifier of the inspection result information.

Next, with reference to FIG. 6(b), inspection processing performed outside the construction site will be described.
Here, the inspection terminal 40 starts the inspection execution program and executes the processing for requesting construction information (step S5-1). Specifically, in the inspection execution screen, when information specifying a range (space) to be inspected is entered in the inspection range input field and a button for requesting construction information is selected, the inspection terminal 40 requests construction information. to the inspection support server 20 .

Next, the control unit 21 of the inspection support server 20 executes extraction processing of inspection object information in the inspection object range (step S5-2). Specifically, the inspection management unit 213 of the control unit 21 acquires the three-dimensional model of the inspection range from the CIM information storage unit 25 . This three-dimensional model is associated with an element identifier (rebar identifier or joint identifier) corresponding to each element.

Next, the control unit 21 of the inspection support server 20 executes processing for transmitting the three-dimensional model of the inspection target range (step S5-3). Specifically, the inspection management unit 213 of the control unit 21 acquires the joint management information 260 including the joint identifiers included in the inspection target range from the joint management information storage unit 26 . The inspection management unit 213 identifies joints for which the inspection date is not recorded in the acquired joint management information 260 as uninspected. The inspection management unit 213 acquires the coordinates of the joints identified as uninspected in the three-dimensional model, and sets the color information of these joints to a color different from that of the inspected joints (for example, when the inspected joints are green). Set uninspected joints to red, if any. Then, the inspection management unit 213 displays, on the touch panel display of the inspection terminal 40, a three-dimensional model in which the uninspected joint is distinguished from the inspected joint by coloring.

Next, the inspection terminal 40 executes a process of identifying the location to be inspected (step S5-4). Specifically, the inspection terminal 40 identifies the joint identifier of an uninspected joint selected by the supervisor from among the joints included in the displayed three-dimensional model, and transmits it to the inspection support server 20 .

Then, the control unit 21 of the inspection support server 20 executes a transmission process of construction information to be inspected (step S5-5). Specifically, the inspection management unit 213 of the control unit 21 acquires joint management information 260 including the acquired joint identifier from the joint management information storage unit 26 . The inspection management unit 213 then outputs the generated inspection screen data to the inspection terminal 40 . This inspection screen includes an input field for each inspection item.

For example, an inspection screen 120 shown in FIG. 8 is displayed. The inspection screen 120 includes a joint identifier, a joint position, a construction item information display field 121, an inspection result entry field 122, and a construction image 175. FIG. Furthermore, this inspection screen 120 includes a save button and a cancel button.

Then, the inspection terminal 40 executes inspection result information transmission processing (step S5-6). Specifically, while viewing the construction item information in the construction item information display column 121 and the construction image 175 on the inspection screen 120, if there is no problem with the inspection items, the supervisor enters the inspection date and name as the inspection results. Fill in field 122 .
Then, when the save button is selected, the inspection terminal 40 associates the input inspection result with the joint identifier and transmits it to the inspection support server 20 .

The control unit 21 of the examination support server 20 executes registration processing of the examination result information (step S5-7) as in step S4-4.

On the other hand, the inspection terminal 40 redisplays the three-dimensional model of the inspection target range. Then, when an uninspected joint is selected, the control unit 21 of the inspection support server 20 executes the processes after step S5-4 described above.

Specifically, the control unit 21 acquires the joint management information 260 associated with the joint identifier included in the acquired three-dimensional model. Then, the control unit 21 identifies, in the acquired joint management information 260, joints in the joint management information 260 in which predetermined construction items are not recorded as unregistered construction information. Then, the control unit 21 acquires the coordinates of the joints specified as not having construction information registered in the three-dimensional model, and sets the color information of these joints to a color different from that of registered joints (for example, an inspected joint is green). , set the uninspected joints to a red color that stands out from the inspected green).
The work terminal 30 displays the received three-dimensional model on the touch panel display. When the joint 15 to be written is selected on the three-dimensional model, the work terminal 30 identifies the joint identifier of this joint 15 and executes the processes from step S2-2.

In the above embodiment, the work terminal 30 uses the joint identifier of the joint selected on the three-dimensional model for the joint 15 to which information is to be written in the process of writing identification information to the RFID tag of the joint (WS3). identified. In the write target identification process, after identifying one joint identifier, the work terminal 30 may identify the next joint 15 of the RFID tag 16 to be written. For example, the work terminal 30 is provided with a position information acquisition unit such as an acceleration sensor or a GPS sensor. Using the measured value of the position information acquisition unit, the movement distance and direction of the work terminal 30 are calculated from the position of the joint 15 whose construction information is registered, and the position of the movement destination is specified. Then, the work terminal 30 identifies the joint 15 near the destination position as the next write target. As a result, the writing process with the RFID tags 16 of many joints 15 can be efficiently performed.
Similarly, in the on-site inspection process, the inspection terminal 40 identifies one joint identifier using the measurement value of the position information acquisition unit, and then identifies the next joint 15 of the RFID tag 16 to be inspected. may

Information to be recorded in the memory of the RFID tag 16 may be information to be referenced during inspection. For example, part of the reinforcing bar type and construction information, or other information may be stored. Further, the RFID tag 16 may also store construction images.

- In the above embodiment, the inspection support server 20 stores the construction information in association with the joint identifier recorded in the RFID tag 16 . The construction information about the joint at the site position corresponding to the position of the three-dimensional model is not limited to being stored in direct association with the joint identifier. For example, a storage medium identifier pre-stored in the memory of the RFID tag 16 may be used. In this case, the joint management information 260 is provided with a storage medium identifier data area. Furthermore, the work terminal 30 reads the storage medium identifier in the memory of the RFID tag 16 with a reading device, associates this recording medium identifier with the joint identifier specified in the write target specifying process (step S1-4), Send to the inspection support server 20 . The control unit 21 of the inspection support server 20 associates the joint identifier with the storage medium identifier and stores them in the joint management information storage unit 26 . As a result, the joint identifier can be specified using the storage medium identifier, so that joint construction information can be managed without recording the joint identifier in the RFID tag 16 .
- In the above-described embodiment, the working terminal 30 and the inspection terminal 40 are separate. The work terminal 30 and the inspection terminal 40 may be the same terminal. In this case, the reader/writer 18 is connected to the terminal.
