<First Embodiment>
Hereinafter, a construction support system according to a first embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram showing an overall outline of a construction support system according to the first embodiment of the present invention. In this figure, reference numeral 1 denotes a construction support system.

(Overview of construction support system)
As shown in FIG. 1, the construction support system 1 according to the present embodiment is a system that is used for construction work by the crane 10, particularly for carrying the member 5, and supports construction work of the operator 9 a of the crane 10 at the construction site. is there. Specifically, the construction support system 1 according to the present embodiment acquires target arrangement information stored in advance for each member 5 that is picked up and transported by the crane 10, and is under construction based on the target arrangement information. The operator 9a of the crane 10 is notified of the position (target position) and the azimuth (target azimuth) to which the member 5 is to be attached. Here, the “target arrangement information” is information indicating a target position and a target direction where the member 5 is to be attached in the construction under construction. Details of the “target position” and “target direction” included in the target arrangement information will be described later.
The construction support system 1 notifies the operator 9a in real time of the current position (current position) and direction (current direction) of the member 5 being transported by the crane 10 simultaneously with the target position and target direction of the member 5. That is, the construction support system 1 simultaneously notifies the operator 9a of the current position and current direction of the member 5 currently being conveyed and the target position and target direction of the member 5 to the operator 9a. Construction support for navigating so that the member 5 can be quickly and accurately transported to the target point is enabled.
Hereinafter, the functional configuration of each functional unit constituting the construction support system 1 according to the present embodiment will be described with reference to FIG.

(Functional configuration of crane)
First, the functional configuration of the crane 10 will be described. As a crane 10 according to the present embodiment, a tower crane is taken as an example.
The crane 10 is a heavy machine installed at a predetermined construction site, and performs various operations such as turning, undulation, and hoisting while lifting a construction material (member 5 such as a steel frame) of a construction object (such as a high-rise building). It is a heavy machine that performs and transports it to the desired position of the construction.

As shown in FIG. 1, the crane 10 includes a crane hook 11, a wire 12, a jib 13, an operation chamber 14, and a mast 15. The crane hook 11 is configured to include a hook main body portion 11c below the hook blocks 11a and 11b that accommodate pulleys (not shown) supported by the wires 12. The crane hook 11 is suspended from a jib head 13 a at the tip of the jib 13 by a wire 12.
As shown in FIG. 1, the hook body 11c of the crane hook 11 is configured to be rotatable in a horizontal direction (a direction parallel to the ground surface) about the hook rotation axis O2. Therefore, the member 5 hung on the hook body 11c can be rotated according to the rotation of the hook body 11c. By doing in this way, at the time of attachment of member 5 to a construction object, since the installation worker who waits on a construction object can rotate member 5 freely, construction efficiency can be improved.

The operation room 14 is a part that causes the crane 10 to execute various operations when the operator 9a enters the room and operates a predetermined operation panel. A PLC (Programmable Logic Device) 14a provided in the operation room 14 is a functional unit that acquires operation information of various operations (described later) of the crane 10 based on operations of the operator 9a. The mast 15 is a part that is fixed to the ground surface and supports the entire crane 10 (the jib 13 and the operation chamber 14).
The operator 9a can change the inclination angle φ of the jib 13 based on the operation of the crane 10 in the operation room 14 (undulation). Then, the height of the jib head 13a changes, and the operator 9a can lift the member 5 hung (described later) on the crane hook 11 and lift the member 5 to the height of the building.
The operator 9a can turn the jib 13 in the horizontal direction around the turning axis O1 (see FIG. 1). By doing in this way, the operator 9a can move the picked-up member 5 in the turning direction. During turning, the crane hook 11 and the slung member 5 move along the circumference of the working radius r (the horizontal distance from the turning axis O1 to the hook rotation axis O2) shown in FIG. The working radius r can be adjusted by the jib inclination angle φ due to undulations. In the following description, how much the jib 13 has pivoted from the predetermined reference position with the jib pivot axis O1 as an axis is represented by a jib pivot angle α.
In addition, the operator 9a can change the length of the wire 12 (winding and lowering). This operation is used for adjustment when the member 5 is raised or lowered to a desired position.

  The various operations such as hoisting, turning, and winding of the crane 10 described above can be acquired via the PLC 14a as operation information based on numerical values such as the jib inclination angle φ, the jib turning angle α, and the winding length of the wire 12. That is, the PLC 14a functions as a jib state acquisition unit that acquires jib state information (jib inclination angle φ, jib turning angle α, etc.) indicating the state of the jib of the crane 10 during the transport operation. The PLC 14a is electrically connected to the construction support device 23, which will be described later, in the operation room 14, and the PLC 14a always outputs the acquired jib state information to the construction support device 23 through the connection.

(About slinging work)
As shown in FIG. 1, the slinging worker 9 b waits at the slinging work place T and performs a work of slapping the member 5 on the hook main body portion 11 c of the crane hook 11. At this time, the lifting wire 5b is attached to the member 5, and the worker performs a slinging operation by placing the lifting wire 5b on the hook body 11c. The slinging operation is performed so that the center of gravity 5n overlaps with the hook rotation axis O2 while the member 5 is kept horizontal when the sling is lifted by the lifting operation of the crane 10.

Hereinafter, the operation of establishing wireless communication in the proximity is referred to as “touch access”. When the slinging worker 9b performs touch access, the member information reading device 22 acquires information stored in the member IC tag 21. Further, when the member information reading device 22 acquires information from the member IC tag 21 by touch access, the member information reading device 22 immediately transmits the acquired information to the construction support device 23 described later via another communication means (wireless LAN) described later. To do.

The member information reading device 22 further has a function of acquiring initial deviation angle information indicating a deviation angle of the direction in which the specified member 5 is directed before being lifted with respect to the direction in which the specified member 5 is to be attached. . Here, “the direction in which the member 5 is to be attached” specifically refers to the direction that should be directed when the member 5 is transported by the crane 10 and attached to the building, and in the design stage of the building. The orientation is uniquely determined for each member 5 based on the design information. Further, “the direction in which the member 5 faces before lifting” specifically refers to the direction in which the member 5 faces at the time when the member 5 is arranged in the slinging work place T.
In addition, “the direction in which the member 5 should be directed (directed)” is a direction in which one fixed point (excluding the center of gravity 5n) of the member 5 should be directed (directed) with respect to the center of gravity 5n. In the following description, it is assumed that the member 5 is a columnar steel frame material, and in this case, the “direction in which the member 5 should be directed” refers to the longitudinal direction in which the member 5 that is a columnar steel frame extends. One direction parallel to the direction.
The member information reading device 22 acquires the difference (deviation) angle of the “orientation before lifting” with respect to the “azimuth to be attached” as initial deviation angle information, and the construction support together with the member identification information and the target arrangement information. Transmit to device 23. A specific means for acquiring the initial deviation angle information will be described later.

  Based on the jib state information input from the PLC 14a, the hook angle information received from the hook angle acquisition unit 20, the target arrangement information received from the member information reader 22, and the initial deviation angle information, the construction support device 23 It is an apparatus that presents navigation information for construction support to 9a. The construction support apparatus 23 according to the present embodiment is a general-purpose personal computer (personal computer) and a general peripheral device (personal computer monitor or the like). Specifically, the construction support device 23 indicates to the operator 9a the target position and target orientation to be attached to the construction of the member 5 based on the received target arrangement information, and also provides jib state information and hook angle information. And based on the initial deviation azimuth information, a process for indicating the current position and the current azimuth of the member 5 being transported is performed.

The member identification information is identification information unique to the member 5 to which the member IC tag 21 is attached, and the construction support apparatus 23 that has received this member identification information can identify the type of the member 5. The member IC tag 21 stores target arrangement information preset for each member 5. As shown in FIG. 4, the target arrangement information includes a target position (x1, y1, z1) indicating a position where the member 5 should be attached to the construction, and an orientation that is directed when the member 5 is attached to the construction. The target direction θ1 is specified. Here, the target position (x1, y1, z1) indicates the position of the center of gravity to which the member 5 is to be attached, the name of the center line (referred to as the core) of the wall or pillar constituting the construction under construction, Expressed as deviation from the core. For example, at the target position (X5 + 1300, Y3-3500), the center of gravity of the member 5 is a point 1300 mm in the x-axis direction and −3500 mm in the y-axis direction from the intersection of the thread core X5 and the thread core Y3. Similarly, for z1 (height direction), for example, if z1 = 5F + 300, the position of +300 mm is indicated in the z-axis direction (direction perpendicular to the ground surface) with reference to the height of the floor on the fifth floor of the building. .

  The target azimuth θ1 is an angle that specifies an azimuth to be faced when the member 5 is attached to a construction, with an absolute reference azimuth P0 (that is, a north azimuth) described later as 0 °. For example, when the target azimuth θ1 is stored as 15 °, the direction of the member 5 which is parallel to the longitudinal direction of the member 5 which is, for example, a columnar steel frame is shifted from the north azimuth by 15 ° to the west. It means that it should be installed in the state. This target arrangement information is uniquely determined for each member 5 based on the design information of the target building.

  The member IC tag 21 may include information other than the member identification information and the target arrangement information shown in FIG. For example, information indicating the weight, size (length), shape, and position of the center of gravity of the member 5 may be included. In the above description, the target azimuth θ1 indicates a azimuth shifted from the north azimuth by θ1 to the west. However, in another embodiment, the target azimuth is not limited to this aspect, and is deviated from the north azimuth by θ1 east. The direction may be indicated. Furthermore, the target orientation θ1 may not be an angle based on the actual north direction, but may be an angle based on the direction toward the core x axis of the construction or the direction toward the core y axis.

The worker (writing worker) performs the work of writing the member identification information, the target arrangement information, and the like regarding the member 5 described above in advance on each member IC tag 21. Specifically, the writing worker first executes a predetermined reading application 221 in the member information reading device 22 owned by the writing worker. When the reading application 221 is executed, the tag information writing unit 221c of the member information reading device 22 receives member identification information, target arrangement information, and the like (FIG. 4) from the writing operator via the operation input unit 226. Accept input. When the information input by the writing worker is completed, the tag information writing unit 221c executes a writing process based on the input completion operation of the worker. When the tag information writing unit 221c detects touch access to the member IC tag 21 desired by the writing worker during the writing process, the tag information writing unit 221c stores various information input via wireless communication in the member IC tag 21. Perform the writing process. This operation may be performed either before or after the member IC tag 21 is attached to the member 5.
Further, the tag information writing unit 221c further receives arbitrary information from among member identification information registered in advance, a street name (eg, “X5”, “Y3”, etc.), and a floor number (eg, “5F”, etc.). A function that can be selected may be provided. By doing in this way, the effort of the information input operation by a writing worker can be reduced.

(Functional configuration of hook angle acquisition unit)
FIG. 5 is a first diagram illustrating a functional configuration of the hook angle acquisition unit according to the first embodiment of the present invention. FIG. 6 is a second diagram showing a functional configuration of the hook angle acquisition unit according to the first embodiment of the present invention.
Next, the functional configuration of the hook angle acquisition unit 20 will be described with reference to FIGS. 5 and 6. As described above, the hook angle acquisition unit 20 according to the present embodiment acquires hook angle information indicating the horizontal rotation angle (hook angle β) of the hook main body 11c that lifts the member 5.

  FIG. 5 shows a side view of a part of the crane hook 11. As shown in FIG. 5, the hook angle acquisition unit 20 includes an angle reading device 20a and a plurality of hook IC tags 20b. The hook IC tag 20b is an IC tag attached to the hook main body 11c, and a plurality of hooks are arranged along the horizontal rotation direction of the hook main body 11c of the crane hook 11 (see FIG. 5). Each of the hook IC tags 20b rotates with the horizontal rotation of the hook body 11c.

  In FIG. 6, the plane sectional view of the crane hook 11 is shown. As shown in FIG. 6, hook IC tags 20b are attached so as to surround the hook main body 11c, for example, every 30 ° along the horizontal rotation direction of the hook main body 11c. Each of the plurality of hook IC tags 20b stores hook angle information uniquely assigned thereto. For example, the hook IC tag 20b stores angle information of “0 °”, “30 °”, “60 °”,..., “330 °”, respectively.

  As shown in FIGS. 5 and 6, the angle reading device 20a is provided on the inner wall side of the hook block 11a (the side facing the hook main body portion 11c), and is used for a hook corresponding to the hook angle β of the hook main body portion 11c. This is a functional unit that faces one of the IC tags 20b and reads hook angle information stored in the one hook IC tag 20b by wireless communication. As the hook main body portion 11c rotates horizontally along the hook rotation axis O2, each of the hook IC tags 20b is also rotated. In other words, the angle reading device 20a faces one of the hook IC tags 20b that is uniquely determined according to the hook angle β of the hook main body 11c, and establishes wireless communication with the hook IC tag 20b. Get information.

The angle reading device 20 a includes a wireless communication module 201. The wireless communication module 201 is a communication interface for establishing wireless communication based on, for example, a wireless LAN. The wireless communication module 223 provided in the member information reading device 22 described above, the wireless communication module 232 provided in the construction support device 23, and It has an equivalent function.
The angle reading device 20a sequentially transmits the hook angle information read from the facing one IC tag for hook 20b to the construction support device 23 via the wireless communication module 201.

In addition, the hook angle acquisition part 20 is not limited to the above-mentioned aspect.
For example, a mode in which a base having a predetermined thickness is provided between the hook main body portion 11c and the hook IC tag 20b may be employed. By doing so, it is possible to prevent the hook IC tag 20b from being directly attached to the hook main body portion 11c formed of metal and making it difficult to perform wireless communication using an electromagnetic field. The underlayer is formed of a dielectric (insulator), more preferably a magnetic material having a high magnetic permeability.
Further, in the above example, the description has been given as the aspect in which the 12 hook IC tags 20b are attached at every hook angle of 30 °. However, the present embodiment is not limited to this aspect. For example, the number N of hook IC tags 20b may be determined by [N = hook diameter A × π / IC tag width I]. Here, the hook diameter A is a diameter of a cross-sectional circle perpendicular to the rotation axis O2 of the hook body 11c (FIG. 6). However, when it has the said foundation | substrate, it shall include the thickness of the foundation | substrate. The IC tag width I is the width of the hook IC tag 20b in the circumferential direction of the hook body 11c (FIG. 6). For example, when the IC tag 20b for hooks with I = 18 mm is attached to the hook body part 11c with A = 90 mm, N≈16 can be obtained by the above formula.
The hook angle acquisition unit 20 includes a predetermined acceleration sensor that senses the angular velocity of the hook main body 11c, and specifies the horizontal rotation angle (hook angle β) of the hook main body 11c from the angular velocity information detected from the acceleration sensor. However, a method of obtaining as hook angle information may be used. In addition, as the hook angle acquisition means, various methods that can specify the hook angle β of the hook body 11c that can rotate horizontally and acquire it as hook angle information may be applied.
Moreover, the hook angle acquisition part 20 may be provided with two or more angle reading devices 20a in the hook blocks 11a and 11b. In this way, the construction support device 23 receives the hook angle information from each of the plurality of angle reading devices 20a, so that redundancy is increased and more accurate hook angle information can be acquired.

(Regarding the method of obtaining initial deviation angle information)
FIG. 7 is a first diagram illustrating a method of acquiring initial deviation angle information according to the first embodiment of the present invention. FIG. 8 is a second diagram showing a method for acquiring initial deviation angle information according to the first embodiment of the present invention. FIG. 8 is an enlarged view of the main part of FIG.
Hereinafter, the method for acquiring the initial deviation angle information will be described in detail with reference to FIGS.

As shown in FIG. 7, in the slinging work place T, the member 5 is arranged in a state of facing a predetermined direction. The member 5 is provided with a member IC tag 21 in which member identification information about the member 5 and target arrangement information are stored. Further, the member reference direction Q 0 specified for each member 5 in advance is written on the member 5 in the vicinity of the member IC tag 21. Here, the member reference orientation Q0 is an orientation that coincides with the absolute reference orientation P0 (north orientation) when the member 5 is correctly attached to the construction under construction. That is, in this embodiment, when the member 5 is correctly attached, the member reference direction Q0 always faces the north direction. Conversely, when the member 5 is not correctly attached, the absolute reference orientation P0 and the member reference orientation Q0 do not match.
Specifically, the member reference orientation Q0 may be handwritten on the basis of design information created in advance when the member IC tag 21 is attached.
In the above description, the method of acquiring the initial deviation angle information of the member 5 by preliminarily describing the north direction on the member 5 and performing touch access according to the direction is described. It is not limited. For example, the member 5 may be marked with the x-axis orientation or the y-axis orientation of the core of the construction when the member 5 is attached to the construction. In this case, it is assumed that the correspondence between the direction of each axis of the core and the actual north direction is recorded in the member information reading device 22 in advance. Then, the reading application 220 obtains the actual direction of each axis of the core with reference to the actual north direction acquired through the geomagnetic sensor 228, and then the deviation of the axis of the member 5 from the current direction of each axis. It is assumed that processing for calculating an angle is performed.

Here, a specific work procedure when the slinging worker 9b slings the member 5 will be described.
First, the slinging worker 9b executes the reading application 221 in the member information reading device 22 owned by himself / herself. The reading application 221 activates the function of the touch access module 222 and waits for touch access to the member IC tag 21. At this time, the reading application 221 displays an image 22a for notifying the slinging worker 9b of the absolute reference azimuth (actual north azimuth) detected by the geomagnetic sensor 228 on the image display unit 227 of the member information reading device 22. May be.

  Next, the slinging worker 9b attaches the lifting wire 5b to the hook body 11c (after completion of the slinging work), and the rotation position of the hook body 11c is stable without the lifting wire 5b slacking. Then, touch access is performed using the member information reading device 22. Then, at the time of this touch access, the slinging worker 9b performs the touch access while making the orientation of the body of the member information reading device 22 coincide with the member reference orientation Q0, as shown in FIG.

When detecting the touch access, the shift angle acquisition unit 221b calculates the shift angle Δθ of the direction in which the body of the member information reading device 22 is directed with respect to the actual “north” direction detected by the geomagnetic sensor 228, This is acquired as body orientation information. Here, since the slinging worker 9b matches the orientation of the body of the member information reading device 22 with the member reference orientation Q0, the deviation angle Δθ indicated by the body orientation information acquired at the time of this touch access is an absolute reference. This coincides with the deviation angle of the azimuth indicated by the member reference azimuth Q0 before lifting the member 5 with respect to the azimuth P0 (actual north azimuth). That is, the deviation angle Δθ indicated by the main body orientation information acquired here is the orientation (current orientation) at the time when the member 5 is disposed at the slinging work place T with respect to the orientation (target orientation) where the member 5 is to be attached to the construction object. ). The deviation angle acquisition unit 221b acquires the initial angle deviation information in this way. Next, the deviation angle acquisition unit 221b performs processing of immediately transmitting the initial angle deviation information acquired at the time of touch access to the construction support apparatus 23.
The tag information acquisition unit 221a performs a process of immediately transmitting the member identification information and the target arrangement information acquired from the member IC tag 21 by the touch access to the construction support device 23.

  On the other hand, when receiving the member identification information, the target arrangement information, and the initial angle deviation information from the member information reading device 22 after the touch access, the construction support device 23 detects that there has been a touch access by the slinging worker 9b. When detecting the touch access, the construction support device 23 stores the hook angle β indicated by the hook angle information received from the hook angle acquisition unit 20 at that time as the initial hook angle β1. Similarly, the construction support apparatus 23 stores the jib turning angle α input from the PLC 14a when the touch access is detected as the initial turning angle α1.

In the operation of the slinging worker 9b described above, the slinging worker 9b may further perform an operation of selecting the crane 10 to perform wireless communication before performing touch access. Specifically, the slinging worker 9b performs an operation of selecting a crane identification ID previously assigned to each of the plurality of cranes 10 in the reading application 221 before executing the touch access. In this case, the member information reading device 22 has a function of establishing wireless communication only with the construction support device 23 provided in the crane 10 corresponding to the crane identification ID based on the crane identification ID selected by the slinging worker 9b. It shall have.
By doing in this way, when there are a plurality of cranes 10 at the construction site, only the crane 10 that actually lifts the member 5 is member identification information, target arrangement information, and initial angle deviation information about the member 5. Can be sent. In addition, when the access point for wireless LAN mentioned above is provided in the crane hook 11, when the member information reader 22 does not exist in the area where the communicable ranges of different access points overlap, The selection operation of the crane identification ID may be omitted by establishing wireless communication with one communicable access point.

Moreover, the construction support apparatus 23 may include a crane specifying unit that specifies a crane from which the member 5 specified by the member identification information is to be lifted out of the plurality of cranes 10. Then, when the specified crane is a crane 10 other than the crane 10 including the own device, the construction support device 23 sends various information acquired through the wireless communication module 232 to the specified crane 10. You may have the function to forward.
For example, when the crane 10 (No. 2 machine) originally performs touch access to the member 5 to be lifted, the member information reading device 22 establishes wireless communication with the construction support device 23 provided in the crane 10 (No. 1 machine). The construction support device 23 provided in the crane 10 (No. 1 machine) performs the following processing.
That is, the crane specifying means of the construction support device 23 provided in the crane 10 (No. 1 machine) includes the member identification information about the member 5 received from the member information reading device 22 after the touch access, and the member management database 234a provided to itself. The crane 10 to which the member 5 is to be lifted is specified by comparing with the member information stored in advance. And the construction support apparatus 23 with which the crane 10 (No. 1 machine) was equipped specified that it was a member which the crane 10 (No. 2 machine) should lift rather than an own machine (No. 1 machine) based on the process of the said crane specific means. In the case, various types of information received from the member information reading device 22 are transferred to the construction support device 23 provided in the crane 10 (No. 2 machine). This transfer process is performed, for example, via an inter-crane LAN connecting each of the plurality of cranes 10.
By doing in this way, even if it is a case where various information about member 5 which member information reading device 22 transmits by touch access is transmitted to any crane 10, finally member 5 is actually used. The member identification information, the target arrangement information, and the initial angle deviation information about the member 5 can be transmitted to the crane 10 to be picked up.
In the above case, it is assumed that the member management database 234a previously stores a crane identification ID indicating which member 10 should be lifted by which crane 10 in association with the member identification information.
The crane determination means may determine which crane 10 is the member to be lifted by the member 5 based on the crane identification ID selected by the operation of the slinging worker 9b, not the received member identification information. Good.

(Example of image displayed by the construction support device)
9, 10, and 11 are a first diagram, a second diagram, and a third diagram showing images displayed on the image display unit of the construction support apparatus according to the first embodiment of the present invention. .
The construction support device 23 is based on various information received (input) from the member information reading device 22, the hook angle acquisition unit 20 and the PLC 14a and acquires the state of the jib 13, the crane hook 11 and the member 5 during transportation ( The position and orientation) and the state (target position and target orientation) to be attached to the construction of the member 5 are notified to the operator 9a of the crane 10. Hereinafter, an example of a display image displayed on the image display unit 236 in the process in which the actual carrying work of the member 5 is performed will be described in order. It is assumed that the CPU 230 of the construction support apparatus 23 is in a state where a predetermined construction support application 231 is being executed.

First, FIG. 9 illustrates an example of an image displayed on the image display unit 236 immediately after the slinging worker 9b performs the slinging work and performs touch access using the member information reading device 22.
Based on the target arrangement information (target positions x1, y1, z1, and target direction θ1) received from the member information reading device 22, the target position / azimuth calculation unit 231a of the construction support apparatus 23 is configured to have the slung member 5 in the construction. The target member image P indicating the state to be attached is displayed on the image display unit 236 (FIG. 9). The origin of the coordinates (x1, y1, z1) is a predetermined point on the ground surface of the construction site, and the reference of the target direction θ1 is 0 ° for the north direction. In addition, the target position / azimuth calculation unit 231a stores information on the specific shape (size, length, center of gravity, etc.) of the member 5 based on the received member identification information, and the member management database 234a. And may be reflected in the target member image P. In this case, information regarding the specific shape of the member 5 may be stored in advance in the member IC tag 21, and the member information reading device 22 may acquire and transmit the information.

  On the other hand, the current position / orientation calculation unit 231b of the construction support device 23 is based on the jib state information indicating the state of the jib 13 (the turning angle α and the jib inclination angle φ) input from the PLC 14a. The current jib image R showing the 13 states is displayed on the image display unit 236 (FIG. 9). Here, the turning angle of the jib 13 immediately after the touch access is the initial jib turning angle α1.

  Further, the current position / orientation calculation unit 231b displays, on the image display unit 236, a current member image Q indicating the state (current position, current direction) of the member 5 at the current time (before fishing) based on the initial deviation angle information and the jib state information. Display (FIG. 9). The current position / orientation calculation unit 231b refers to the jib state information input from the PLC 14a, and matches the position of the center of gravity 5n of the member 5 with the hook rotation axis O2, so that the current position of the member 5 disposed in the slinging work place T is reached. The position (x0, y0) can be specified. In addition, the current position / orientation calculation unit 231b can specify the direction (current direction) in which the member 5 faces in the stage before lifting from the deviation angle Δθ of the member reference direction Q0 with respect to the absolute reference direction P0.

  Next, the operator 9a performs hoisting and hoisting by the crane 10 from the state shown in FIG. The operator 9a can adjust the working radius r by undulations. The operator 9a can adjust the lifting height (lifting height) of the member 5 by undulation and winding. The head is adjusted based on the member arrangement position z1. After adjusting the working radius r and the lift, the operator 9a then performs a turn based on the target member image P. The current position / azimuth calculation unit 231b reflects the jib state that changes as the crane 10 moves up and down and the position / orientation of the member 5 in the current jib image R and the current member image Q in real time.

FIG. 10 shows an example of an image displayed on the image display unit 236 when the operator 9a turns the jib 13.
The operator 9a adjusts the working radius r and the lift of the member 5 by undulation and hoisting, and then turns the jib 13 to carry the member 5 to a desired position of the construction. Here, the current position / azimuth calculation unit 231b sequentially inputs the jib state information corresponding to the undulation / turning of the jib 13 from the PLC 14a, while the current jib image R showing the state of the jib 13 and the current position of the member 5, the current The current member image Q indicating the azimuth is updated. The operator 9a checks the display images that are sequentially updated as the undulations / turns are performed, so that the jib 13 is appropriately undulated / turned so that the center of gravity 5n of the member 5 coincides with the target position (x1, y1). Can be performed (FIG. 10). The difference between the current jib turning angle α and the initial jib turning angle α1 is expressed as a difference turning angle Δα (= α−α1).

  Here, assuming that the hook angle β has not changed from the initial hook angle β1 during the undulation / turning in FIG. 10, the current position / orientation calculation unit 231b has a member reference direction Q0 with respect to the absolute reference direction P0 as shown in FIG. The current member image Q is displayed so that the shift angle is Δθ + Δα. By confirming the display image displayed on the image display unit 236, the operator 9a can recognize that the current orientation of the member 5 is deviated by Δθ + Δα from the orientation to be originally attached to the construction ( FIG. 10).

FIG. 11 shows an example of an image displayed on the image display unit 236 when the member attaching worker standing by at the construction object adjusts the orientation of the member 5.
The operator 9a moves the member 5 so that the current position (x0, y0) of the member 5 coincides with the target position (x1, y1), and then the member attaching operator who waits on the construction starts from the crane hook 11. The lifting wire 5b is removed and the member 5 is attached to the construction. Here, the member attaching operator adjusts the direction in which the member 5 is directed by horizontally rotating the member 5 so that the member 5 is directed in the direction in which the member 5 is to be attached before the removal. Since the hook body 11c that suspends the member 5 can rotate about the hook rotation axis O2, the attaching operator can rotate the member 5 together with the hook body 11c.

The rotation angle β of the hook main body portion 11c changes in accordance with the adjustment work of the orientation of the member 5 by the attaching operator. While calculating the differential rotation angle Δβ (= β−β1) of the hook angle β received from the hook angle acquisition unit 20 at the time of adjusting the direction of the member 5 with respect to the initial hook angle β1, the current position / direction calculation unit 231b The display of the current member image Q is updated based on Δβ (FIG. 11). The operator 9a looks at the image displayed on the image display unit 236, and confirms whether or not the orientation is adjusted so that the orientation of the target member image P and the orientation of the current member image Q coincide with each other. If the member 5 has not been adjusted to the correct orientation, the operator 9a contacts the installation operator via a transceiver or other appropriate communication means.
At the time of FIG. 10, the orientation of the member 5 is shifted by Δθ + Δα from the orientation that should originally be attached to the construction. Therefore, the installation operator sets the orientation of the member 5 so that the differential rotation Δβ = − (Δθ + Δα). You just have to adjust it.

  In the above, the example of the display image displayed on the image display part 236 in the process in which the actual conveyance work of the member 5 is advanced was demonstrated. In the above example, it is assumed that the hook angle β has not changed from the initial hook angle β1 during undulation / turning in the jib 13, and the change in the display image accompanying the turning of the jib 13 (FIG. 10) The change in the display image (FIG. 11) accompanying the change in the above has been described in order. However, in the actual transport operation, the turning of the jib 13 and the change of the orientation of the member 5 can occur simultaneously. In this case, the current position / orientation calculation unit 231b specifies a deviation Δθ ′ of the orientation of the member 5 being transported at each time point during transport with respect to the bearing to be attached to the construction, using the general formula shown in Formula (1). be able to.

(Processing flow of member information reader)
FIG. 12 is a diagram showing a processing flow of the member information reading apparatus according to the first embodiment of the present invention.
Next, the processing flow of the CPU 220 of the member information reading device 22 will be described step by step with reference to FIG.

  First, when the slinging worker 9b performs a predetermined operation from the operation input unit 226 of the member information reading device 22, the CPU 220 executes the reading application 221 (step S220). The reading application 221 immediately activates the function of the touch access module 222 and waits for touch access to the member IC tag 21. Specifically, when the wireless communication with the member IC tag 21 is not established in the touch access module 222 (when the touch access is not performed), the reading application 221 repeats step S221 and waits (in step S221). “NO”). When wireless communication with the member IC tag 21 is established in the touch access module 222 (when touch access is made), the process proceeds to the next step (“YES” in step S221).

When wireless communication with the member IC tag 21 is established, the tag information acquisition unit 221a inputs the member identification information and the target arrangement information stored in the member IC tag 21 via the touch access module 222. The content is transmitted to the construction support apparatus 23 via the wireless communication module 223 (step S222).
On the other hand, the deviation angle acquisition unit 221b calculates the deviation angle Δθ of the azimuth in which the body of the member information reading device 22 is directed with respect to the absolute reference azimuth (actual north azimuth) detected by the geomagnetic sensor 228 (step S223). . As described above, the slinging worker 9b performs touch access in a state where the direction in which the main body of the member information reading device 22 faces is matched with the member reference direction Q0 written on the member 5 (see FIG. 8). The acquired deviation angle Δθ coincides with the azimuth deviation angle at the time when the member 5 is disposed on the slinging work place T with respect to the azimuth when the member 5 is attached to the construction object.
Next, the reading application 221 determines whether or not an end process has been received from the slinging worker 9b (step S224). Here, when the reading application 221 has not received the termination process (“NO” in step S224), the reading application 221 returns to step S221 and waits for touch access again. On the other hand, when the reading application 221 receives the end process (“YES” in step S224), the reading application 221 ends its own process.

  Through the above processing, the member information reading device 22 transmits information for identifying the staking member 5 and information indicating the position and direction where the member 5 should be attached to the construction to the construction support device 23. Further, the member information reading device 22 specifies the direction in which the member 5 arranged in the slinging work place T is facing, and transmits the information to the construction support device 23.

(Processing flow of construction support equipment)
FIG. 13 is a diagram showing a processing flow of the construction support apparatus according to the first embodiment of the present invention.
Next, the processing flow of the CPU 230 of the construction support apparatus 23 will be described step by step with reference to FIG.

  First, the CPU 230 of the construction support apparatus 23 is in a state where the construction support application 231 is being executed. The construction support application 231 is in a state where the hook angle information is constantly received from the hook angle acquisition unit 20 and the jib state information is input from the PLC 14a. In this state, the construction support application 231 waits for reception of member identification information and target arrangement information from the member information reader 22. Specifically, when a wireless signal is not received from the member information reading device 22, the construction support application 231 repeats step S230 and waits (“NO” in step S230). When the tag information is received from the member information reading device 22, the process proceeds to the next step (“YES” in step S230).

Next, the target position / orientation calculation unit 231a displays an image of the target member image P based on the target arrangement information (target positions X1, Y1, Z1, and target direction θ1) included in the tag information received from the member information reading device 22. This is displayed on the part 236 (FIG. 9). Further, the target position / orientation calculation unit 231a acquires information on the specific shape (size, length, center of gravity position, etc.) of the member 5 based on the received member identification information, and the specific position of the member 5 is acquired. A target member image P indicating the shape is displayed.
On the other hand, the current position / orientation calculation unit 231b displays a current jib image R indicating the current state of the jib 13 on the image display unit 236 based on the jib state information input from the PLC 14a. Further, the current position / orientation calculation unit 231b indicates the current state (current position, current direction) of the member 5 at the present time (before fishing) based on the initial deviation angle information and the jib state information received from the member information reading device 22. The member image Q is displayed on the image display unit 236 (step S232).

  Next, the construction support application 231 stores the jib turning angle α input from the PLC 14a at this time (touch access) as the initial jib turning angle α1. Further, the construction support application 231 stores the hook angle β received from the hook angle acquisition unit 20 at this time as the initial hook angle β1 (step S233). The initial jib turning angle α1 and the initial hook angle β1 are used as initial values for specifying the position and orientation of the member 5 that is transported by undulation, turning, winding, etc. from this point.

  Thereafter, the operation of transporting the member 5 (undulation, turning, winding, etc.) is started by the operation of the operator 9a (step S234). While the member 5 is being transported, the current position / orientation calculation unit 231b receives the jib state information from the PLC 14a, and further receives the hook angle information from the hook angle acquisition unit 20 (step S235). Then, the current position / orientation calculation unit 231b sequentially updates the current jib image R and the current member image Q in accordance with the progress of the transportation work based on the various information acquired in step S235 (step S236).

Next, the construction support application 231 determines whether or not the conveyance of the member is completed (Step S237). Here, as a means for notifying the construction support application 231 of the completion of the conveyance of the member 5, the operator 9 a confirming that the member 5 has been removed from the hook body 11 c performs a predetermined input operation on the construction support device 23. A method of inputting and notifying can be used.
When the construction support application 231 does not input a notification of the completion of the transportation of the member 5 (“NO” in step S237), the construction support application 231 returns to step S234 to change the state of the jib 13 that changes sequentially during transportation, the position of the member 5, The image (Q, R) indicating the azimuth is updated. On the other hand, when the construction support application 231 inputs a notification of completion of transportation (“YES” in step S237), the construction support application 231 ends its own processing. The construction support application 231 may return to step S230 after this and wait for reception of information on the new member 5 to be transported next.

Through the above-described processing of the construction support apparatus 23, the operator 9a allows the position and orientation of the member 5 at each time point during operation (current member image Q) and the position and orientation to which the member 5 should be attached (target member image P). It becomes possible to operate the crane 10 while confirming each of the above. By doing in this way, the operator 9a can convey the member 5 correctly to the position which should be originally attached.
Further, the construction support apparatus 23 according to the present embodiment is based on the initial deviation angle information received from the member information reading apparatus 22 and the hook angle information received from the hook angle acquisition unit 20, and the direction in which the member 5 being transported faces. Can be identified and this can be notified to the operator 9a. Therefore, the operator 9a can further determine whether or not the member 5 is attached to the construction with the correct orientation.
As mentioned above, according to the construction support system 1 which concerns on the 1st Embodiment of this invention, the attachment mistake of a member can be prevented more reliably.

In addition, the construction support system 1 which concerns on 1st Embodiment is not limited to the above-mentioned content.

Therefore, it was decided to send and receive various information. However, in the construction support system 1 according to another embodiment, transmission / reception of information among the hook angle acquisition unit 20, the member information reading device 22, and the construction support device 23 is realized by, for example, a wired connection via a predetermined communication cable. It may be done.

  Further, in the construction support system 1 according to the present embodiment, the member IC tag 21 stores target arrangement information indicating the position and orientation at which the member 5 is to be attached to the construction object. In the above description, the target arrangement information is received from the member information reading device 22. However, in the construction support system 1 according to another embodiment, the member IC tag 21 stores only member identification information for specifying the staking member 5, and the construction support device for the target arrangement information. It is good also as what is acquired from the member management database 234a stored in 23 HDD234 based on the said member identification information.

Moreover, in this Embodiment, although the tower crane is made into the application object as the crane 10, the kind of crane is not limited, It is possible to apply also to other cranes, such as a truck crane.
In addition, it is possible to appropriately replace the components in the above-described embodiments with known components without departing from the spirit of the present invention.

<Second Embodiment>
Next, a construction support system according to a second embodiment of the present invention will be described with reference to the drawings.
FIG. 14 is a diagram showing a functional configuration of a construction support system according to the second embodiment of the present invention. In addition, about the functional structure which is common in 1st Embodiment among the functional structures of the construction assistance system which concerns on 2nd Embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.
As shown in FIG. 14, the crane hook 11 of the crane 10 according to the present embodiment is provided with a speaker 202, an audio microphone 203, and a photographing camera 204.

The speaker 202 according to the present embodiment announces whether or not the touching operator 9b performs touch access, whether the touch access is correctly performed, member identification information about the touch-accessed member 5, and other information, It functions as a notification means for notifying the slinging worker 9b. Specifically, the speaker 202 can communicate with the construction support apparatus 23 via wireless communication means. And the construction assistance apparatus 23 which concerns on this embodiment transmits the reproduction | regeneration information which shows the content of the member identification information to the speaker 202, when member identification information is received from the member information reading apparatus 22 after touch access. The speaker 202 announces member identification information about the member 5 that has performed touch access to the slinging worker 9b based on the received reproduction information.
By doing in this way, the slinging worker 9b can recognize whether or not the member information reading device 22 has been reliably touch-accessed, and further whether or not there is an error in the type of the member 5 that has sled. it can.

Further, the construction support device 23 included in the crane 10 specified based on the processing of the crane specifying means is specified when member identification information or the like about the member 5 is transferred from another crane 10. Reproduction information indicating the content of the member identification information is transmitted to the speaker 202 provided in the crane 10.
In this way, when there are a plurality of cranes 10, the announcement is made from the speaker 202 provided in the crane 10 that should actually lift the member 5, regardless of which crane 10 the member information reader 22 has performed wireless communication with. Will be done. Therefore, the slinging worker 9b can recognize which crane 10 the member 5 touch-accessed should be picked up when a plurality of cranes 10 exist.

Further, the construction support device 23 receives the initial deviation angle information acquired by the member information reading device 22 at the time of touch access, and the jib turning angle at the current deviation angle Δθ or Δθ of the member 5 in the slinging work place T. An angle (Δθ + Δα) including Δα may be calculated, and reproduction information indicating the obtained angle information may be generated. And the construction support apparatus 23 performs the process which transmits the reproduction | regeneration information which shows the angle information to the speaker 202, and the speaker 202 is about the member 5 which performed the touch access to the slinging worker 9b based on the received reproduction | regeneration information. Announce initial offset angle information.
For example, it is assumed that the angle (Δθ + Δα) obtained by adding the jib turning angle Δα to the deviation angle Δθ of the member 5 in the slinging work place T is 45 °. In this case, when the slinging worker 9b performs touch access while aligning the orientation of the member information reading device 22 main body with the member reference orientation Q0, the construction support device 23 calculates Δθ + Δα as 45 ° based on the received initial deviation angle information. Then, the reproduction information indicating the angle information is transmitted to the speaker 202. Then, the speaker 202 notifies the slinging worker 9b based on the received reproduction information that the angle Δθ + Δα is 45 °. The slinging worker 9b rotates in advance by an angle (−45 °) before the member 5 is transported by the crane hook 11 (immediately after being lifted) according to the notified angle 45 °. I do.
If it does in this way, when conveyance to the construction object of member 5 by crane 10 will be completed, since member 5 will face the direction which should just be attached, while preventing attachment mistake of member 5, The mounting work can be made more efficient.
In addition to the above function, the construction support device 23, when the crane 10 completes the transportation of the member 5 to the construction, is directed to the installation worker waiting on the construction via the speaker 202 at that time. It may have a function of announcing the deviation angle Δθ ′ (formula (1)). In this case, for example, the operator 9a performs a predetermined notification operation via the operation input unit 235 of the construction support device 23 after finishing the operation of transporting the member 5 to the target position. When receiving the notification operation, the construction support device 23 performs a process of transmitting reproduction information indicating the deviation angle Δθ ′ at that time to the speaker 202.
By doing in this way, the construction support apparatus 23 can make an installation operator recognize how much the member 5 should be rotated in which direction.

Further, the construction support apparatus 23 according to the present embodiment reproduces predetermined audio data when the current member image Q matches the target member image P, and a speaker provided in the crane hook 11 via the wireless communication module 232. You may make it broadcast from 202. In this case, the wireless communication module 232 of the construction support device 23 wirelessly communicates with the speaker 202, and when the current position and the current direction of the member 5 match the target position and the target direction, respectively, It functions as an arrangement completion notification means for notification.
By doing in this way, the member installation worker standing by in the construction recognizes that the current position and the current direction of the member 5 being transported coincide with the target position and the target direction set in advance for the member 5. can do.
However, the arrangement completion notification unit is not limited to the mode using the speaker 202. As another modification, for example, a member attaching operator or the like may be notified by lighting of a lamp provided in the crane hook 11. Further, the construction support device 23 may perform communication by wired connection using the speaker 202 (and the lamp) and a communication cable provided in the crane 10.

Furthermore, the construction support apparatus 23 acquires the voice of the operator 9a waiting in the operation room 14 as voice data, and also a hang-up worker 9b waiting in the hang-up work place T or a member waiting in the construction through the speaker 202. The reproduction process is performed for the installation worker.
