Japanese Unexamined Patent Publication No. 2014-198630

Here, as described above, by providing the crane with a camera, the shooting information obtained by the camera may be effectively used. For example, by taking a picture of the surroundings of a crane with a camera, it is possible to grasp the work around the crane and the flow line of a person. As a result, the operator can grasp the state of work of one crane and the surrounding situation.

However, at the crane work site, a plurality of cranes may be arranged. In this case, the work planner needs to manage the work of each crane throughout the work site. On the other hand, a method of individually collecting reports and managing information on the work contents of each crane at the work site can be considered, but this method places a heavy load on managing the entire work site. , May not be able to perform good management.

The present invention has been made to solve such a problem, and provides a crane work management system and a management device capable of satisfactorily managing a plurality of cranes arranged at a work site. The purpose.

The crane work management system of the present invention is a crane work management system that manages the work of a plurality of cranes arranged at a work site, and is information for acquiring cargo handling operation information related to the cargo handling operation of each of the plurality of cranes. It includes an acquisition unit and a management unit that collects and integrates cargo handling operation information acquired by information acquisition units of a plurality of cranes, and the management unit outputs integrated cargo handling operation information.

The crane work management system of the present invention collects the information acquisition unit that acquires the cargo handling operation information regarding the cargo handling operation of each of the plurality of cranes, and the cargo handling operation information of each of the plurality of cranes acquired by the information acquisition unit. It has a management department to integrate. As a result, the management unit can collect cargo handling operation information related to cargo handling operation from each of the plurality of cranes arranged at the work site, and integrate the collected cargo handling operation information of each crane. In addition, the management unit can output cargo handling operation information in an integrated state. As a result, the user can refer to the cargo handling operation information of a plurality of cranes arranged at the work site in an integrated state. From the above, it is possible to satisfactorily manage a plurality of cranes arranged at the work site.

The management unit may be able to embed the cargo handling operation information of each crane in the control chart represented by the overall coordinate system set for the work site. In this case, the management unit can output what kind of cargo handling operation each crane has performed in the overall coordinate system. As a result, the user can easily refer to which crane performs what kind of cargo handling operation in the entire work site.

The management unit may grasp the position of the hanging tool as the position of the suspended load from the traveling, turning, and pulling operations of the crane. The traveling, turning, and pulling motions of the crane are information that can be acquired by the equipment already installed in the crane. Moreover, the position of the hanger can be specified based on these movements. Then, the position of the suspended load can be specified from the position of the hanging tool. Therefore, the management unit can grasp the position of the suspended load by using the equipment already installed in the crane.

The management unit may grasp the timing at which the crane lifts the suspended load and the timing at which it lands on the ground based on the detection result of the load meter provided on the crane. The load gauge is an existing device on the crane. Therefore, the management unit can grasp the lifting timing and the landing timing by using the equipment already installed in the crane.

The crane may have a photographing section. As a result, the management unit can acquire the shooting information of the surroundings of each crane and link it to the control chart. As a result, the user can effectively use the shooting information of each surrounding area.

The crane may include legs extending in the vertical direction, and the photographing portion may be provided on the legs so that images can be taken from the horizontal direction. As a result, the management unit can acquire shooting information obtained by shooting the periphery of each crane from the horizontal direction. For example, if only a photographing unit for photographing the state of the lower side of the crane from the upper side is provided, the state around the crane can be grasped only in a plane. On the other hand, when the shooting information taken from the horizontal direction is acquired, the state around the crane can be grasped three-dimensionally.

The cargo handling operation information collected and integrated by the management unit may include information on the suspended load related to the cargo handling of the crane. In this case, the management unit can manage the operation of the crane by associating information on the suspended load such as the shape, size, center of gravity position, and weight of the suspended load, for example.

The crane management system further includes a work planning unit that plans the work of a plurality of cranes based on the cargo handling operation information integrated in the management unit, and the work planning unit is a suspended load related to the cargo handling of the crane and the crane. You may plan your work using the spatial information of. As a result, the user can use the cargo handling operation information integrated in the management unit for work planning.

The work planning unit may display information for planning the work on the output unit. As a result, the user can easily plan the work while visually confirming the information.

The work planning department may be able to modify the created plan. For example, if the planned work and the actual work are different, the plan can be modified.

The management unit may be able to output cargo handling operation information in real time. In this case, the user can quickly grasp the state of the crane.

The management unit may adjust the display mode according to the state of each crane and display the state of each crane on the output unit. In this case, the user can visually and quickly grasp the state of the crane by checking the output unit.

The work management system further includes an information terminal that outputs cargo handling operation information, and the information terminal may be capable of inputting at least information on the work content of the crane and the start and end of the work content. In this case, since it is possible to input information based on the work actually performed at the work site of each crane, it is possible to share the actual work results at other places.

The work management system 100 further includes a work planning unit that plans the work of a plurality of cranes based on the cargo handling operation information integrated in the management unit, and the work planning unit indicates the work contents according to the time in the cranes. The work information may be displayed on the output unit, and the output unit may visually display the progress status of the work information in real time. In this case, at each site, it is possible to confirm the actual progress of the work contents planned by the work planning department in real time.

Hereinafter, a preferred embodiment of the crane work management system and the management device of the present invention will be described with reference to the drawings.

FIG. 1 is a block configuration diagram showing a block configuration of a crane work management system 100 according to an embodiment of the present invention. FIG. 2 is a plan view showing an arrangement example of a plurality of cranes 20 at a work site. FIG. 3 is a side view of a part of the crane 20 shown in FIG. The work management system 100 is a system for managing a plurality of cranes 20 arranged at a work site. As shown in FIG. 1, the work management system 100 includes a management device 10 (management unit), various information acquisition units provided on the crane 20, and an output unit 15.

First, an example of the arrangement and configuration of the crane 20 will be described with reference to FIGS. 2 and 3. In this embodiment, a jib crane is exemplified as the crane 20. As shown in FIG. 2, an overall coordinate system having an X-axis and a Y-axis is set for a work site where a plurality of cranes are arranged. For example, four cranes 20A, 20B, 20C, and 20D are arranged at the work site. Cranes 20A and 20B are arranged so as to line up near the Y-axis along the Y-axis. The cranes 20A and 20B can travel in the Y-axis direction along the rail 36 provided parallel to the Y-axis. Cranes 20C and 29D are arranged so as to line up near the X-axis along the X-axis. The cranes 20C and 20D can travel in the X-axis direction along the rail 36 provided parallel to the X-axis.

The cranes 20A, 20B, 20C, and 20D have a jib 31 for suspending a suspended load, a main body 32 for supporting the jib 31, a support column 34 for rotatably supporting the main body 32, and a rail 36 for supporting the support column 34. A traveling unit 33 that can travel along the line is provided. A hanging tool 37 is provided at the tip of the wire extending from the jib 31, and the hanging load 38 is hung by the hanging tool 37. Therefore, the position of the suspended load 38 coincides with the position of the hanging tool 37. The origins PGA, PGB, PGC, and PGD of relative coordinates are set at the turning centers of the cranes 20A, 20B, 20C, and 20D. Further, the positions of the hanging tool 37 and the hanging load 38 are set as coordinate points PCA, PCB, PCC, and PCD.

The jib 31 swivels in the swivel direction DR together with the hanger 37, and the radial position of the hanger 37 can be changed depending on the size of the pull-in radius with respect to the main body 32. Therefore, the positions of the coordinate points PCA, PCB, PCC, and PCD can be moved within the range of the circle indicated by the alternate long and short dash line in FIG. Further, the positions of the coordinate points PCA and PCB can be changed to the traveling direction D1 parallel to the Y-axis direction by traveling the cranes 20A and 20B along the rail 36. The positions of the coordinate points PCC and PCD can be changed to the traveling direction D2 parallel to the X-axis direction by traveling the cranes 20C and 20D along the rail 36. The coordinate points PCA, PCB, PCC, and PCD of the cranes 20A, 20B, 20C, and 20D can be moved to a position where the factory building BD can be avoided.

As shown in FIG. 1, the crane 20 includes a timing detection unit 21 (information acquisition unit), a position detection unit 22 (information acquisition unit), a photographing unit 23, and an information transmission / reception unit 24.

The timing detection unit 21 and the position detection unit 22 function as an information acquisition unit for acquiring cargo handling operation information regarding each cargo handling operation of the crane 20. The timing detection unit 21 is a device capable of acquiring information capable of detecting the lifting timing for lifting the suspended load 38 with the hanging tool 37 and the landing timing for landing the suspended load 38. For example, the timing detection unit 21 is composed of a load meter that detects the load acting on the hanger 37. That is, the measured load of the load meter rises sharply at the lifting timing and sharply decreases at the landing timing. Therefore, the measured load of the load meter is information that makes it possible to detect the lifting timing and the landing timing.

The timing at which the load meter measures the load may be when the load stabilizes after lifting (a few seconds after lifting). The timing detection unit 21 is not limited to the load meter as long as it can acquire information that enables detection of the lifting timing and the landing timing. For example, as the timing detection unit 21, a camera or the like that acquires image information that enables detection of lifting timing and landing timing by image processing may be adopted, and control information such as motor torque may also be adopted.

The position detection unit 22 is a device capable of acquiring information capable of detecting the position of the suspended load 38. For example, the position detection unit 22 is composed of a position detection device that detects the traveling position of the crane 20, the turning position of the jib 31, and the retracting position of the jib 31. That is, if the traveling position of the crane 20, the turning position of the jib 31, and the retracting position of the jib 31 are determined, the positions of the hanging tool 37 and the suspended load 38 can be specified. Therefore, the traveling position of the crane 20, the turning position of the jib 31, and the pulling position of the jib 31 are information that makes it possible to detect the position of the suspended load 38. The position detection unit 22 is not particularly limited as long as it can acquire information that enables the position of the suspended load 38 to be detected. For example, as the position detecting unit 22, a position measuring instrument such as GPS provided on the hanging tool 37 may be adopted, or a distance from the rail end measured by a laser range finder or the like may be adopted.

The photographing unit 23 is composed of a camera that photographs the state around the crane 20. As the photographing unit 23, for example, a camera 23a provided at the top of the main body 32 and a camera 23b provided at the tip of the jib 31 are provided (see FIG. 3). The camera 23a has a photographing range E1 capable of photographing a state around the main body 32 in a wide range. The camera 23b has a photographing range E2 capable of photographing the state around the suspended load 38. When the photographing unit 23 is provided in the turning portion, the turning angle may be detected and correction may be applied so that the image is always in a fixed direction, and a mechanism for mechanically reversing the photographing unit 23 is provided. It may be provided. The shooting unit 23 may acquire a still image as shooting information, or may acquire a moving image.

By using the shooting information acquired by the shooting unit 23, it is possible to grasp the state of distribution around the crane 20 and the flow line of people. The shooting unit 23 is not particularly limited in the shooting timing of the shooting unit 23. For example, the photographing unit 23 may take an image at the lifting timing and the landing timing. Further, the photographing unit 23 may take a picture while moving the suspended load 38. In addition, the photographing unit 23 may take a picture immediately before the start of the day's work or immediately after the day's work is completed. Alternatively, the photographing unit 23 may constantly perform photographing during the work of the day.

The information transmission / reception unit 24 transmits the acquired information to the management device 10. In addition, the information transmission / reception unit 24 receives information from the management device 10. The information transmission / reception unit 24 transmits / receives information by wireless communication.

The management device 10 is a device that collects and integrates cargo handling operation information of each of the plurality of cranes 20 acquired by the timing detection unit 21 and the position detection unit 22. Further, the management device 10 outputs cargo handling operation information in an integrated state. The management device 10 transmits the integrated cargo handling operation information to the output unit 15 and outputs the integrated cargo handling operation information via the output unit 15. The integrated cargo handling operation information is information indicating which crane 20 performed what kind of cargo handling operation in a state of being linked to each other. The management device 10 can embed the cargo handling operation information of each crane in the control chart represented by the overall coordinate system set for the work site. By embedding the crane's cargo handling operation information in the control chart represented by the overall coordinate system, the user can easily grasp what kind of cargo handling operation was performed by the crane placed where in the entire work site. Will be. The user is, for example, a work planner who makes a work plan for each crane in an office. As described above, the cargo handling operation information embedded in the control chart represented by the overall coordinate system corresponds to the cargo handling operation information in the integrated state.

Next, a specific configuration of the management device 10 will be described. The management device 10 includes an information acquisition unit 11, a calculation unit 12, an output control unit 13, and an information transmission / reception unit 14.

The information acquisition unit 11 acquires the information acquired by the timing detection unit 21, the position detection unit 22, and the photographing unit 23 in each crane 20. The calculation unit 12 performs various calculation processes in the management device 10. Specifically, the calculation unit 12 grasps the position of the hanger 37 from the traveling, turning, and pulling operations of the crane 20 based on the information acquired by the position detecting unit 22. For example, the calculation unit 12 converts the encoder information of the traveling unit 33, the turning angle information of the jib 31, and the pull-in radius information of the jib 31 into the coordinates of the entire coordinate system. Further, the calculation unit 12 grasps the position of the hanging tool 37 as the position of the suspended load 38. The calculation unit 12 may perform all the calculation processing for grasping the positions of the hanging tool 37 and the suspended load 38 from the traveling, turning, and pulling operations of the crane 20, but the position detecting unit 22 of the crane 20. May perform a part or all of the arithmetic processing by having the arithmetic unit.

Further, the calculation unit 12 grasps the timing at which the crane 20 lifts the suspended load 38 and the timing of landing based on the detection result of the load meter constituting the timing detection unit 21 provided on the crane 20. The calculation unit 12 performs a calculation so as to convert the position of the suspended load 38 at the lifting timing into the coordinate position of the entire coordinate system (see FIG. 2). Further, the calculation unit 12 performs a calculation so as to convert the position of the suspended load 38 at the landing timing into the coordinate position of the entire coordinate system. In this way, the calculation unit 12 grasps the position of the hanger 37 based on the detection result of the position detection unit 22 as the position of the suspended load 38. Further, the calculation unit 12 can reflect the position of the suspended load 38 grasped in this way in the overall coordinate system.

Although the calculation unit 12 may perform all the calculation processing for grasping each timing based on the detection result of the load meter of the crane 20, the timing detection unit 21 of the crane 20 has the calculation unit. Part or all of the arithmetic processing may be performed. The calculation unit 12 may associate the acquisition location of the photographing information acquired by the photographing unit 23 of each crane 20 with the overall coordinate system. As a result, it is possible to grasp which part of the overall coordinate system the image or moving image of the shooting information shows.

The output control unit 13 controls the output mode of the cargo handling operation information collected from each crane 20. The output control unit 13 edits the collected cargo handling operation information so that it can be output in an integrated state. The output control unit 13 embeds cargo handling operation information of each crane 20 in a control chart showing the entire work site as shown in FIG. 2 in the overall coordinate system. The output control unit 13 displays the grasped position of the suspended load 38 on the control chart represented by the overall coordinate system, and attaches a link to access the shooting information to the position. At this time, the output control unit 13 manages the position of the suspended load 38 calculated by the calculation unit 12 in association with the timing at which the crane 20 lifts the suspended load 38 and the timing of landing, and is represented by the overall coordinate system. Reflect in the figure.

For example, as shown in FIG. 4, the output control unit 13 enables the state of the work site to be displayed as an image 50 on the monitor of the output unit 15. For example, the calculation unit 12 grasps the information that "the crane 20C lifts the suspended load 38A at the time X1 and lands at the time X2", and "the suspended load 38A of the crane 20C is at the coordinate A1 at the time X1". It is assumed that the information "exists and exists at the coordinate A2 at the time X2" is grasped. In this case, the output control unit 13 reflects in the image 50 how the suspended load 38A is lifted with the coordinate A1 as the suspension position and landed with the coordinate A2 as the landing position. Further, the calculation unit 12 grasps the information that "the crane 20C lifts the suspended load 38B at the time Y1 and lands at the time Y2", and "the suspended load 38B of the crane 20C is at the coordinate B1 at the time Y1". It is assumed that the information "exists, moves with the traveling of the crane 20C, and exists at the coordinate B2 at the time Y2" is grasped. In this case, the output control unit 13 reflects in the image 50 how the suspended load 38B is lifted with the coordinate B1 as the suspension position and landed with the coordinate B2 as the landing position.

In the example of FIG. 4, the coordinates of lifting and landing are indicated by dots, and the moving direction of the suspended load 38 is indicated by arrows. Further, the output control unit 13 may be able to display the grasped cargo handling record information as Table 51. Although only the information of the crane 20C is shown in FIG. 4, the image 50 shows all the control charts represented by the overall coordinate system and all the cranes 20A, 20B, 20C, and 20D. good. Table 51 may also show cargo handling records for all cranes 20A, 20B, 20C, 20D.

The output control unit 13 may edit the shooting information acquired by the shooting unit 23 into a predetermined output mode so that the output unit 15 can output the shooting information. For example, the output control unit 13 may create a composite image showing the state of the entire work site as shown in FIG. 2 by using the image acquired by the photographing unit 23 of each crane 20. The output control unit 13 may reflect the movement information of the suspended load 38 as shown in the image 50 of FIG. 4 with respect to the composite image. The output control unit 13 may trim the overlapping portion when synthesizing the images. However, the output control unit 13 does not have to use a photograph as an image showing the state of the work site, and may use a simplified illustration. The output control unit 13 may control the output so that, for example, when the user specifies a specific time and place at the work site, an image or a moving image corresponding to the time and place can be output. For example, the output control unit 13 may store the shooting information of the shooting unit 23 like a drive recorder so that it can be referred to later.

The information transmission / reception unit 14 transmits the cargo handling operation information in the managed state to the output unit 15. Further, the information transmission / reception unit 14 receives the information from the crane 20. The information transmission / reception unit 14 transmits / receives information by wireless communication. The information transmission / reception unit 14 may transmit the information output from the output control unit 13 to the output unit 15 in real time, and collectively at the timing when the information is accumulated to some extent (for example, at the end of one day's work). It may be output to the output unit 15.

The output unit 15 outputs the integrated cargo handling operation information output from the management device 10 to the user. The output unit 15 is composed of, for example, an information terminal such as a personal computer owned by the user. Therefore, the output unit 15 is usually installed at a place away from the crane 20 such as an office. The output unit 15 displays the cargo handling operation information edited by the output control unit 13 on the monitor. Further, the output unit 15 may output cargo handling operation information on paper by a printer or the like. The management device 10 can transmit information to a plurality of output units 15. The output unit 15 may further include a portable information terminal such as a smart phone or a tablet terminal.

Next, with reference to FIG. 5, the flow of the processing contents of the work management system 100 of the crane 20 according to the present embodiment will be described. FIG. 5 is a flowchart showing the processing contents of the work management system 100 of the crane 20 according to the embodiment of the present invention. The process shown in FIG. 5 is repeatedly executed by the management device 10. The process shown in FIG. 5 may be performed at regular time intervals, or may be performed at the timing when information is acquired by any of the cranes 20.

As shown in FIG. 5, the information acquisition unit 11 acquires information that enables detection of the lifting timing and the landing timing from the timing detecting unit 21 of the crane 20 (step S10). The information acquisition unit 11 acquires information that enables the position of the suspended load 38 to be detected from the position detection unit 22 of the crane 20 (step S20). The information acquisition unit 11 acquires photography information from the imaging unit 23 of the crane 20 (step S30). Next, the calculation unit 12 converts various information acquired in steps S10, S20, and S30 into the overall coordinate system, and embeds the information in the control chart represented by the overall coordinate system (step S40). Further, the output control unit 13 edits the output information so that the information embedded in the control chart represented by the overall coordinate system in step S40 can be output to the output unit 15 (step S50). Then, the information transmission / reception unit 14 outputs the output information edited in step S50 to the output unit 15 (step S60).

Next, the operations and effects of the work management system 100 and the management device 10 of the crane 20 according to the present embodiment will be described.

The work management system 100 of the crane 20 includes a timing detection unit 21 and a position detection unit 22 as information acquisition units for acquiring cargo handling operation information related to each of the cargo handling operations of the plurality of cranes 20, and a timing detection unit 21 as an information acquisition unit. It also includes a management device 10 that collects and integrates cargo handling operation information of each of the plurality of cranes 20 acquired by the position detection unit 22. As a result, the management device 10 can collect cargo handling operation information related to the cargo handling operation from each of the plurality of cranes 20 arranged at the work site, and integrate the collected cargo handling operation information of each crane 20. In addition, the management device 10 can output cargo handling operation information in an integrated state. As a result, the user can refer to the cargo handling operation information of the plurality of cranes 20 arranged at the work site in an integrated state. From the above, it is possible to satisfactorily manage a plurality of cranes 20 arranged at the work site.

The management device 10 can embed the cargo handling operation information of each crane 20 in the control chart represented by the overall coordinate system set for the work site. In this case, the management device 10 can output what kind of cargo handling operation each crane 20 has performed in the overall coordinate system. As a result, the user can easily refer to which crane 20 has performed what kind of cargo handling operation in the entire work site.

The management device 10 determines the position of the hanging tool 37 as the position of the suspended load 38 from the traveling, turning, and pulling operations of the crane 20. The traveling, turning, and pulling operations of the crane 20 are information that can be acquired by the equipment already installed in the crane 20. Further, the position of the hanger 37 can be specified based on these movements. Then, the position of the suspended load 38 can be specified from the position of the hanging tool 37. Therefore, the management device 10 can grasp the position of the suspended load 38 by using the equipment already installed in the crane 20.

The management device 10 grasps the timing at which the crane 20 lifts the suspended load 38 and the timing of landing based on the detection result of the load meter provided on the crane 20. The load meter is an existing device on the crane 20. Therefore, the management device 10 can grasp the lifting timing and the landing timing by using the equipment already installed in the crane 20.

The crane 20 has a photographing unit 23. As a result, the management device 10 can acquire the photographing information obtained by photographing the periphery of each crane 20 and attach it to the control chart. As a result, the user can effectively use the shooting information of each surrounding area.

The management device 10 is a management device 10 that manages the work of a plurality of cranes 20 arranged at the work site, and collects, integrates, and integrates cargo handling operation information regarding the cargo handling operation of each of the plurality of cranes 20. Outputs the cargo handling operation information in the state of being in the state.

According to the management device 10 according to the present embodiment, it is possible to obtain the same operation and effect as the work management system 100 of the crane 20 described above.

Here, in the above-described embodiment, for example, the suspended load 38 related to the cargo handling of the plurality of cranes 20 shown in FIG. 3 is regarded as a point and managed. However, the actual suspended load 38 occupies a predetermined range spatially because it has a certain size, and the position and weight of the center of gravity of the suspended load 38 also affect the operation mode of the crane. The information on the suspended load 38 is information that can be easily obtained because it has already been generated at the time of product design or the like. For example, when the crane 20 conveys a part of a ship, the part of the ship may be manufactured according to the drawing after designing a product and creating a drawing. Therefore, it is possible to easily obtain the information on the suspended load 38 from the information on the drawing.

Therefore, the cargo handling operation information collected and integrated by the management device 10 may include information on the suspended load 38 related to the cargo handling of the crane 20. In this case, the management device 10 can manage the operation of the crane 20 by associating information on the suspended load 38 such as the shape, size, center of gravity position, and weight of the suspended load 38, for example.

The timing at which the management device 10 acquires the information on the suspended load 38 is not particularly limited. For example, the management device 10 may acquire information before the crane 20 actually handles the suspended load 38, or may acquire the information immediately before or during the cargo handling, and the data after the cargo handling is completed. You may get the information while organizing. The management device 10 may effectively utilize the acquired information on the suspended load 38. For example, the management device 10 outputs the operating state of each crane 20 as described above, but the operating state and the information of the suspended load 38 may be linked and managed / output. For example, in the image 50 of FIG. 4, only the coordinates of the suspension positions of the suspended loads 38A and 38B are shown, but the outer shape of the suspended loads 38A and 38B may be shown in the image 50.

Further, as shown in FIG. 6, in the crane management system, the management device 10 includes a work planning unit 60 that plans the work of a plurality of cranes 20 based on the cargo handling operation information integrated by the management device 10. You may prepare further. The work planning unit 60 may plan the work by using the suspended load 38 related to the cargo handling of the crane 20 and the spatial information of the crane 20. As a result, the user can use the cargo handling operation information integrated in the management device 10 for the work planning. The spatial information of the suspended load 38 and the crane 20 refers to the state in which the suspended load 38 and the crane 20 exist in the space, such as the outer shape, position, and orientation of the suspended load 38 and the crane 20. This is the information to be shown.

Further, the work planning unit 60 may display information for performing work planning on the output unit 15. As a result, the user can easily plan the work while visually confirming the information. For example, as shown in FIG. 6, the management device 10 plans how to arrange the suspended load 38 while considering the positions of the large structures 70 and the like existing around the crane 20, and the contents of the plan. May be displayed as an image on the output unit 15. In the image, the crane 20, the suspended load 38, etc. may be displayed as a photograph, or may be shown by a modeled figure or the like.

The work planning unit 60 can suitably plan the work by using the information of the suspended load 38 described above. For example, as shown in FIG. 6, the work planning unit 60 recognizes and defines the rail start point S and the end point E of the crane 20 on the map based on the GPS position information mounted on the crane 20 and the like. Next, the work planning unit 60 defines the design dimensions of the building, fixed object, etc. with reference to the rail start point S, and defines the yard operation space with reference to the track with coordinates. The position of the suspended load 38 (center of the hanging tool) is assigned by the dimension from the rail start point S based on the traveling / turning / retracting position information of the crane 20. The work planning unit 60 links the information of the suspended load 38 (product name, shape, size, center of gravity position, weight, etc.) to the position of the suspended load 38, so that what kind of object can be placed at which position. , When and where to transport can be displayed. Since the center of gravity of the suspended load 38 is calculated in advance at the time of design as transport information at the time of lifting, the shape of the suspended load 38 may be stored and arranged with the position of the center of gravity as the center of the hook. Further, the shape may be memorized by tracing the outer shape from the image. Further, the shape may be recognized by an image recognition camera. It should be noted that these processes may be performed not only when the work planning unit 60 creates a work plan, but also when creating an image showing the actual operation of the crane 20.

The work planning unit 60 plots the work area of the crane 20 (the locus CL1 in the figure shows the maximum radius of the jib and the locus CL2 shows the minimum radius of the jib) on the rail coordinates, and plots the large structure 70 around it on the rail coordinates. Can be displayed. The work planning unit 60 also displays other suspended loads 38. For example, when the crane 20 plans the destination of the suspended load 38D, the user turns at what turning angle θ and how so as not to interfere with the surrounding large structure 70 or another suspended load 38. It is possible to consider whether or not the crane should be transported with a uniform jib radius.

The work planning unit 60 may display the information necessary for the plan to the user and perform the work plan based on the input of the user. Alternatively, the work planning unit 60 may automatically create an optimum work plan in consideration of the positional relationship with the surrounding large structure 70 and other suspended loads 38. Alternatively, the work planning unit 60 may present the automatically created work plan candidates to the user, receive the user's selection or the input of fine adjustment, and create the plan.

The work planning unit 60 may be able to modify the created plan. For example, if the planned work and the actual work are different, the plan can be modified. Specifically, it is assumed that the work planning unit 60 has created a work plan for one day on the day before a certain work day. At this time, it is assumed that the work in the morning was different from the work plan. For example, when the predetermined suspended load 38 is arranged at a position different from the plan, the actual work will be different from the work plan. In such a case, the work planning unit 60 compares the actual work content with the initially created work plan and corrects the work plan in the afternoon.

The management device 10 may be able to output cargo handling operation information in real time. In this case, the user can quickly grasp the state of the crane 20. For example, the management device 10 outputs the output contents shown in FIG. 4 to the output unit 15 in real time while changing the output contents from moment to moment. For example, when the work supervisor has a mobile terminal as an output unit 15 at each site in the factory, the management device 10 displays the current state of each crane 20 in the factory in real time as the mobile terminal of each work supervisor. Output to. As a result, the work supervisor at each site can immediately know the situation at other sites. At this time, a user having a predetermined authority such as a work supervisor may check the image displayed on the output unit 15 and modify the work plan created by the work planning unit 60. The time interval for the management device 10 to update the information of each output unit 15 is not particularly limited, but may be updated every few seconds or every few minutes, for example. When the latest information is output at such a time interval, it corresponds to the fact that it is output in real time.

The management device 10 may adjust the display mode according to the state of each crane 20 and display the state of each crane 20 on the output unit 15. In this case, the user can visually and quickly grasp the state of the crane 20 by checking the output unit 15.

For example, the management device 10 may output an image displaying cargo handling operation information of a plurality of cranes 20 as shown in FIG. 7 to the output unit 15. FIG. 7 shows the arrangement of cranes arranged in the yard, and the state is updated at intervals of several seconds. For example, in a swivel crane, the swivel radius and direction change as the jib is pulled in (see FIG. 3). As shown in FIG. 7, the radius of the crane 20 is indicated by the size of a circle on the layout image. The direction of the jib of the crane 20 is indicated by the direction of the arrow. For locations where the turning radius wraps and is difficult to see, the circle may be made translucent so that the traveling positions of the approaching cranes 20 can be easily seen. In this way, the relationship with the adjacent machine, which is a blind spot in the working radius, can also be visualized. With this circular wrap, it is possible to confirm the possibility of collision depending on the turning direction. The colors and patterns of the circles (distinguished by dot and hatch patterns in the figure) are classified into "operating", "stopping", "abnormality occurring", and "no data: not monitored". This makes it possible to visualize which crane 20 is in what state, in which direction, at what position, and how much working radius it has. In addition, it is possible to determine whether or not a suspended load is suspended by coloring the arrow (triangle in a circle). For example, a hatched arrow indicates that the suspended load is being lifted, and a white arrow indicates that there is no load.

Further, the management device 10 may output an image displaying more detailed cargo handling operation information regarding a specific crane as shown in FIG. 8 to the output unit 15. The specific crane may be one crane or a plurality of cranes traveling on the same rail 36. FIG. 8 will also be described by taking a swivel crane as an example. In FIG. 8, the traveling position of the crane 20 is displayed. That is, in the image, the total length of the pair of parallel rails 36 is represented. Further, with one end of the rail 36 as the origin side, the characters "mileage 〇〇m" are displayed while indicating the crane position with an arrow AP. Further, in the image, 360 ° is expressed by the characters “turning angle + 〇〇 degrees (− ○○ °)” from the reference point while moving the direction of the triangle indicating the jib.

Here, the traveling device and the turning device of the crane 20 each require a brake mechanism in order to prevent escape due to wind. For example, the brake mechanism of the swivel device is a hydraulic brake (combination unit). The brake mechanism of the traveling device is a mechanical fixing device that is engaged with a metal fitting on the ground side. Each brake mechanism is equipped with a limit switch for confirming ON / OFF. The state of each brake mechanism is indicated by an iris mark in the image of FIG. In the image, those with hatching indicate that the fixing device is in the ON state. The iris mark 41 on the upper side of the rail 36 indicates the operating status of the turning brake mechanism. The iris mark 42 on the lower side of the rail 36 indicates the operating state of the traveling brake mechanism. In the case of the traveling brake mechanism, the ground side metal fittings may be installed at one place or a plurality of places in the total length of the rail, and the iris mark corresponds to the position of the upper metal fittings in each place. In the state of FIG. 8, the crane on the left side of the figure is stopped, and the brake mechanisms of the turning device and the traveling device are in the ON state. The crane in the center of the figure is in operation, and the brake mechanisms of the swivel device and the traveling device are in the OFF state. The crane on the right side of the figure is out of control and the operating status is not collected.

Further, the management device 10 may output an image as shown in FIG. 9 to the output unit 15. Here, the situation of hoisting / pulling in will be described as an example. Specifically, in the image, the characters "lift + 〇 〇 m (-○○ °)" are expressed while moving the hook position with respect to the ground. Also, in the image, the characters "pull-in radius 〇〇m" are expressed while moving the hook position with reference to the center of the crane. Further, in the image, the load detected by the load meter is represented by the characters "load 〇〇t".

As described above, the management device 10 expresses the state of the crane 20 in the image by using the “color”, “shape”, “size”, “direction” and “transparency effect” of the symbols, and is a visual state. It is possible to monitor. The management device 10 can enable a plurality of people to simultaneously grasp the operation information in real time by using cloud communication. By using such information, it is possible to monitor the crane condition of the entire factory, and it is possible to quickly respond to unforeseen circumstances. In addition, there is an effect that it is possible to remotely confirm that the safety device for running / turning (prevention of escape) has been forgotten.

By visualizing the state of the crane 20 in real time on the output unit 15, it is possible to instantly grasp the state of the crane in the entire factory. In addition, letters and numerical values are used as an auxiliary, and the state of the crane can be grasped visually by shape, color, size, direction, etc. In addition, it is possible to remotely confirm that the safety device has been forgotten to be hooked.

The crane managed by the present invention is not limited to the jib crane. At least, it is applicable to all swivel cranes. Some functions can be applied to bridge cranes. For example, the present invention may be used in the management of other types of cranes, such as overhead cranes.

For example, with reference to FIGS. 10 and 11, when a bridge crane is adopted as the crane 20, how the photographing unit 23 photographs the periphery of the crane 20 will be described. FIG. 10 is a plan view showing a photographing range of the photographing unit 23 provided on the crane 20 at the work site. FIG. 11 is a schematic view schematically showing how the photographing unit 23 provided on the crane 20 photographs the state around the crane 20. 11 (a) is a plan view, FIG. 11 (b) is a front view, and FIG. 11 (c) is a side view. As shown in FIG. 11B, the bridge-shaped crane 20 includes a girder 91 extending in the horizontal direction and a pair of legs 92, 92 extending in the vertical direction at both ends of the girder 91. At the lower ends of the legs 92, 92, for example, a traveling portion that travels along the rails 93, 93 (see FIG. 10) is provided. As a result, the crane 20 can move in the traveling direction along the rails 93 and 93. Further, the crane 20 includes a trolley portion 94 that moves traversely along the girder 91. The trolley portion 94 moves traversely with the hanging tool suspended.

As shown in FIGS. 11B and 11C, the trolley unit 94 is provided with an imaging unit 23A capable of photographing the lower part of the girder 91. As a result, the photographing unit 23A can take an image from any position in the transverse direction by moving the trolley unit 94. For example, in FIG. 10, in the transverse direction of the crane 20, the photographing range DE1 of the photographing unit 23A at the photographing position P1 shown by the solid line and the photographing range DE2 of the photographing unit 23A at the photographing position P2 shown by the broken line are shown. Further, in the traveling direction, in addition to the shooting position P1 shown by the solid line, shooting is performed at two positions (positions shown by the broken line). As a result, the photographing unit 23A moves in the traveling direction and the traversing direction to perform imaging at a total of six imaging positions. Based on these shooting information and the position information of the crane 20, it is possible to synthesize a plan photograph showing the state of the entire work site WE. By acquiring such a plan photograph at the end of the day's work (or the beginning of the day's work), for example, the administrator can effectively use it when creating a work plan, or a video. It can be used as a daily report. It can also be managed in chronological order.

As shown in FIG. 11B, the photographing units 23B and 23B are provided on the legs 92 and 92, respectively, and can take an image from the horizontal direction. The photographing units 23B and 23B are arranged so as to photograph the inside of the crane 20. That is, the photographing unit 23B is arranged so as to be parallel to the transverse direction and face the leg portion 92 on the opposite side (see also FIG. 11A). The height positions of the shooting units 23B and 23B are not particularly limited, but they are set to intermediate positions (near the center, etc.) of the legs 92 and 92 in the height direction so that the lower side of the girder 91 can be photographed over a wide range. May be done. For example, the shooting units 23B and 23B take pictures at three positions in the traveling direction of FIG. 10, and by synthesizing the obtained shooting information with a plane photograph, the state of the work site WE can be grasped three-dimensionally. ..

As described above, the crane 20 includes legs 92 and 92 extending in the vertical direction, and the photographing portions 23B and 23B are provided on the legs 92 and 92 so that images can be taken from the horizontal direction. As a result, the management device 10 can acquire photographing information obtained by photographing the periphery of each crane 20 from the horizontal direction. For example, when only the photographing unit 23A for photographing the state of the lower side of the crane 20 from the upper side is provided, the state of the periphery of the crane 20 can be grasped only in a plane. On the other hand, when the shooting information taken from the horizontal direction is acquired, the state around the crane 20 can be grasped three-dimensionally. A 3D camera capable of acquiring distance information may be used as the photographing unit 23A or the photographing unit 23B. By using a 3D camera, it is possible to grasp the state around the crane 20 in three dimensions from one direction based on the shooting information.

FIG. 12 is a block diagram showing a crane work management system 100 according to a modified example. In the work management system 100 shown in FIG. 12, information can be input from the information terminal 80 at each location based on the shared information. As shown in FIG. 12, the work management system 100 includes a management device 10 and an information terminal 80. The information terminal 80 is a terminal capable of outputting and inputting information. The information terminal 80 can function as an output unit 15 in the above-described embodiment and modification. Therefore, the information terminal 80 is composed of a personal computer, a smartphone, a tablet terminal, and the like, as in the case of the one illustrated in the output unit 15. In the example shown in FIG. 12, each information terminal 80 can present information and receive information to the site work manager, the crane 20 operator, the office operation manager, and the like.

When the office operation manager confirms an image showing the state of the work site WE as shown in FIG. 10, the operation information is input using the information terminal 80, and the work planning unit 60 creates a work plan. For example, in the information terminal 80 used by the office operation manager, "operation time", "ship number", "block name", "where to transport (baggage)", "transportation equipment", and "weight of baggage" for each work day. You can enter information such as "time to perform work" and "work name". The work planning unit 60 causes the information terminal 80 to display work information indicating the work contents according to the time in the crane 20. The management device 10 shares work plans in real time among office operators, field work managers, drivers, and the like by displaying a screen as shown in FIG. 13 on each information terminal 80, for example. be able to.

The information terminal 80 can input information regarding the work content of the crane 20 and the start and end of the work content. That is, the driver or the person in charge of on-site work, based on the actual work results, "which work", "work start timing (when the load calculation value is stable by hanging the luggage)", and "completion timing (unloading the luggage)". When the work is completed) ”can be input to the information terminal 80. Further, the management device 10 may feed back the information input by each information terminal 80 to the image displayed on the information terminal 80. As a result, the information terminal 80 can visually display the progress status of the work information in real time. Further, when the office operator modifies the work plan according to the progress status, the modified work plan can be displayed on each information terminal 80 to share information in real time.

As shown in FIG. 13, the information terminal 80 can visually confirm which equipment (crane) performs what kind of work at what time at each time. For example, a taskbar corresponding to a timetable is displayed for each crane. For example, in the uppermost crane, it is indicated at what time the work content "task 1" is executed. In addition, the information terminal 80 can display the current time and which work is currently being performed by each crane 20. For example, in FIG. 13, a hatched bar indicates the current time. It also means that the taskbar that touches the bar is the work that is currently being performed. The information terminal 80 may visually identify the taskbar corresponding to the work content currently being performed by devising a display mode such as color coding. For example, in FIG. 13, the taskbars (task 3, task 5-1 and task 5-2) corresponding to the contents of the work currently being performed are grayscaled. The taskbars (tasks 1 and 2) shown to the left of the current time bar mean that the work has already been completed. As the completed taskbar, both the taskbar at the time of planning and the taskbar showing the actual results based on the input of the driver may be displayed. Further, the task bar (task 2-2, task 6) shown on the right side of the current time bar means that the work content has not been started yet. As for the taskbar that has not been started, the taskbar after the correction is displayed if there is a correction according to the actual progress status. Alternatively, if there is a modification, both the taskbar before the modification and the taskbar after the modification may be displayed. Completed taskbars and unstarted taskbars may also be visually identified by color coding or the like. As a result, the work plan of each crane 20 and the execution status of the work plan can be visually confirmed. Further, in FIG. 13, by displaying "transport weight / power consumption" on the upper side of the column for displaying the task bar on which the progress status can be confirmed, the evaluation can be performed together with the progress evaluation of the work.

The work management system 100 further includes an information terminal 80 that outputs cargo handling operation information, and the information terminal 80 can input at least information on the work content of the crane and the start and end of the work content. In this case, since it is possible to input information based on the work actually performed at the work site of each crane 20, it is possible to share the actual work results at other places.

The work management system 100 further includes a work planning unit 60 that plans the work of a plurality of cranes 20 based on the cargo handling operation information integrated by the management device 10, and the work planning unit 60 responds to the time in the crane 20. The work information indicating the work content is displayed on the information terminal 80 (output unit), and the information terminal 80 visually displays the progress status of the work information in real time. In this case, at each site, it is possible to confirm the actual progress of the work contents planned by the work planning unit 60 in real time.

Further, in the work management system 100, the planning work of the office operator can be remotely controlled appropriately while checking the actual results on the video, and the work efficiency can be improved. In addition, by visualizing the forecast and actual operation in real time, it is possible to efficiently carry out process adjustment (change) while checking the progress. In addition, it will be easier to collect the results, import them into other systems, and output daily operation reports. In addition, by leaving the video on a regular basis, it is possible to check the progress (volume management by the daily video report) in chronological order. In addition, the actual results can be utilized as the next planning information.
