Description

[Technical Field]

[0001] The present invention relates to a crane lifting weight monitoring system, a crane lifting weight monitoring method, and a program. [Background technology]

[0002] In the traditional method of managing the schedule and performance of crane lifting work, the crane lifting schedule (planning the number of components to be installed per day and the order in which they will be installed) is created by comprehensively considering the building's structure and construction method, site conditions, construction period, and the placement and number of cranes. The installation time per piece of each component is estimated by reference to actual lifting data from similar construction sites. A plan is then created for how many pieces to lift per day based on the estimated installation time per piece of each component. However, with the conventional method of managing the schedule and results of crane lifting work, it is difficult to grasp the progress of the crane lifting work, such as whether it is going smoothly or behind schedule, in real time during the period from the time the crane lifting work is scheduled to the time the results of the crane lifting work are released, and it is also difficult to share information on the progress of the crane lifting work in real time.

[0003] In the conventional method, the lifting plan is compared with the actual lifting results on-site to improve the daily plan. For example, improvements are made such as increasing the number of pieces to be installed per day or identifying tasks that are taking a long time and changing the setup. Additionally, actual crane lifting records are recorded by ground personnel visually observing the crane's movements and taking handwritten notes of the type of components, installation location, lifting start time, and completion time. To identify which tasks are taking the longest time, detailed measurements and records are sometimes made of the time required for, for example, "rigging → lifting → adjustment → unrigging → return." However, with the traditional handwritten recording method, compiling data takes time and effort. It is particularly difficult to grasp the progress of crane lifting work at super-high-rise construction sites or large construction sites with multiple cranes. Furthermore, with the traditional handwritten recording method, the recorded crane lifting data may end up buried within the crane lifting work site, preventing the construction company from accumulating and sharing the data company-wide.

[0004] Patent Document 1 describes a lifting management system that records and centrally manages lifting performance. In the technology described in Patent Document 1, the lifting management system records and centrally manages the lifting performance of lifting devices such as temporary lifting elevators, tower cranes (climbing cranes), and mobile cranes installed at the construction site of a high-rise building. Incidentally, in the technology described in Patent Document 1, lifting performance data is generated by aggregating and processing the operation log of the lifting device (e.g., load, number of floors, current / voltage values, alarm / fault information, etc.) in order to record and centrally manage the lifting performance of the lifting device. In other words, in the technology described in Patent Document 1, the lifting performance data that is recorded and centrally managed is the aggregated and processed data of, for example, the load, number of floors, current / voltage values, and alarm / fault information, etc., and therefore, simply recording and centrally managing the lifting performance data does not allow for a clear understanding of the lifting operation status of the crane, as if the crane were being monitored from above.

[Figure 4]4 is a flowchart illustrating an example of processing executed in the crane lifting monitoring system 1 of the first embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0012] Hereinafter, embodiments of a crane lifting monitoring system, a crane lifting monitoring method, and a program according to the present invention will be described with reference to the drawings.

[0013] [First embodiment] Fig. 1 is a diagram showing an example of a crane lifting monitoring system 1 according to the first embodiment. Fig. 2 is a diagram showing an example of a building BD and cranes CR (West No. 1 CRW1, West No. 2 CRW2, West No. 3 CRW3, East No. 1 CRE1, East No. 2 CRE2, and East No. 3 CRE3) to which the crane lifting monitoring system 1 according to the first embodiment is applied. In detail, Fig. 2(A) shows the positional relationship between the building BD to which the crane lifting monitoring system 1 according to the first embodiment is applied and, for example, six cranes CR (West No. 1 CRW1, West No. 2 CRW2, West No. 3 CRW3, East No. 1 CRE1, East No. 2 CRE2, and East No. 3 CRE3), and Fig. 2(B) shows an example of the configuration of each crane CR.

[0014] 1 and 2, a crane lifting monitoring system 1 monitors the status of lifting work by a crane CR, such as a climbing crane. The cranes CR monitored by the crane lifting monitoring system 1 include West No. 1 CRW1, West No. 2 CRW2, West No. 3 CRW3, East No. 1 CRE1, East No. 2 CRE2, and East No. 3 CRE3. In another example, the number of cranes CR to be monitored by the crane lifting monitoring system 1 may be any number other than six. In another example, the crane lifting monitoring system 1 may monitor the status of the lifting operation of a crane CR other than a climbing crane, such as a mobile crane.

[0015] In the example shown in Figures 1 and 2, each crane CR (West Crane No. 1 CRW1, West Crane No. 2 CRW2, West Crane No. 3 CRW3, East Crane No. 1 CRE1, East Crane No. 2 CRE2, and East Crane No. 3 CRE3) includes, for example, a moving part CR1, an actuator CR2, a control unit CR3, a sensor CR4, a data collection unit CR5, and an input unit CR6. The moving part CR1 includes, for example, a rotating body, a lifting frame, a jib, a wire, and a hook. The actuator CR2 includes, for example, a motor that drives the moving part CR1. The control unit CR3 includes, for example, a programmable logic controller (PLC) that controls the actuator CR2. The sensor CR4 has functions such as lifting load detection, jib (boom) length detection, jib (boom) angle detection, approach detection, wind speed detection, and fault detection. The data collection unit CR5 collects crane operation information, such as control signals output from the control unit CR3 to the actuators CR2 and output signals from the sensor CR4, for example, every second. The crane operation information collected by the data collection unit CR5 includes, for example, the load value of the suspended load, position information of the movable unit CR1 such as hook coordinates, current / voltage values ​​supplied to the actuator CR2, wind speed, alarm / fault information, lifting height, etc. The input unit CR6 accepts inputs by the crane operator, such as the name of the lifting material and the installation floor number (installation floor). The input unit CR6 may also accept inputs such as the results of work time measurements performed by the crane operator and the details of lifting task formation.

[0016] In the example shown in Figures 1 and 2, the crane lifting monitoring system 1 includes, for example, a lifting monitoring server 11, a terminal device 12, and a schedule management system 13. The lifting monitoring server 11 is configured to be able to communicate with the data collection unit CR5, input unit CR6, terminal device 12, schedule management system 13, etc. of the crane CR via, for example, the Internet, a mobile phone line, a wired LAN, a wireless LAN, Wi-Fi, etc. The terminal device 12 is used to grasp the lifting work status of the crane CR. The schedule management system 13 manages schedule management information for the crane CR (for example, information such as the name of materials to be installed, the planned installation position, and the planned work time). The schedule management system 13 includes a memory unit 13A. The memory unit 13A stores the schedule management information for the crane CR. In the example shown in Figures 1 and 2, the crane lifting monitoring system 1 is equipped with three terminal devices 12 (for example, a terminal device 12 carried by a site worker who needs to understand the lifting work status of the crane CR, a terminal device 12 installed in the work site office, and a terminal device 12 installed in the construction company's headquarters), but in other examples, the crane lifting monitoring system 1 may be equipped with any number of terminal devices 12 other than three.

[0017] 1 and 2, the lifting monitoring server 11 is, for example, a cloud server. The lifting monitoring server 11 includes, for example, an operation information acquisition unit 11A, an input information acquisition unit 11B, a schedule management information acquisition unit 11C, a posture work status calculation unit 11D, a display image generation unit 11E, an analysis unit 11F, and a storage unit 11G. The operation information acquisition unit 11A acquires operation information (e.g., load value of the suspended load, position information of the movable part CR1 such as hook coordinates, current / voltage values ​​supplied to the actuator CR2, wind speed, alarm / fault information, lifting height, etc.) of the crane CR collected by the data collection unit CR5 installed on the crane CR (West No. 1 CRW1, West No. 2 CRW2, West No. 3 CRW3, East No. 1 CRE1, East No. 2 CRE2, and East No. 3 CRE3). The input information acquisition unit 11B acquires input information (e.g., name of lifting material, number of floors to be installed, etc.) entered by the crane operator into the input unit CR6 installed on the crane CR. The schedule management information acquisition unit 11C acquires schedule management information (e.g., name of material to be installed, planned installation position, planned work time, etc.) of the crane CR managed by the schedule management system 13.

[0018] The posture work status calculation unit 11D calculates the posture and work status of the crane CR based on the operation information of the crane CR (West No. 1 CRW1, West No. 2 CRW2, West No. 3 CRW3, East No. 1 CRE1, East No. 2 CRE2, East No. 3 CRE3) acquired by the operation information acquisition unit 11A. In other words, the posture work status calculation unit 11D reproduces the work status of the crane CR based on the operation information of the crane CR acquired by the operation information acquisition unit 11A. The display image generation unit 11E generates an animated image of the crane CR that changes over time, based on the posture and work status of the crane CR calculated by the posture work status calculation unit 11D, and corresponds to an image taken from above the crane CR. The analysis unit 11F combines the operation information of the crane CR acquired by the operation information acquisition unit 11A (load value of the load, position information of the movable part CR1 such as hook coordinates, current / voltage values ​​supplied to the actuator CR2, wind speed, alarm / fault information, lifting height, etc.), the input information acquired by the input information acquisition unit 11B (name of the lifting material, number of floors on which it is to be installed, etc.), and the schedule management information of the crane CR acquired by the schedule management information acquisition unit 11C (name of the material to be installed, planned installation position, planned work time, etc.), to analyze in real time the progress of the lifting work of the crane CR (e.g., name of the lifting material, load value of the load, cumulative lifting weight, actual number of pieces lifted, planned number of pieces lifted, progress rate which is the actual number of pieces lifted / planned number of pieces lifted, etc.). The memory unit 11G stores the progress of the lifting work of the crane CR analyzed by the analysis unit 11F and an image showing the progress of the lifting work of the crane CR generated by the display image generation unit 11E.

[0019] The terminal device 12 includes a display unit 12A and an operation unit 12B. Display unit 12A displays animated images of cranes CR (West No. 1 CRW1, West No. 2 CRW2, West No. 3 CRW3, East No. 1 CRE1, East No. 2 CRE2, East No. 3 CRE3) generated by display image generation unit 11E. Display unit 12A is capable of displaying in real time around the animated images of cranes CR images generated by display image generation unit 11E showing the progress of the lifting work of cranes CR (name of lifting material, load value of the load, cumulative lifting weight, actual number of pieces lifted, planned number of pieces lifted, progress rate which is the actual number of pieces lifted / planned number of pieces lifted). Display unit 12A is also capable of displaying images showing the progress of the lifting work of cranes CR (name of lifting material, load value of the load, cumulative lifting weight, actual number of pieces lifted, planned number of pieces lifted, progress rate which is the actual number of pieces lifted / planned number of pieces lifted) stored in memory unit 11G. The operation unit 12B accepts input operations by the user of the terminal device 12.

[0020] FIG. 3 is a diagram showing an example of a display screen of the terminal device 12. As shown in FIG. 3, an animated image of the crane CR (animated image of the crane CR that changes over time) equivalent to an aerial image of the crane CR generated by the display image generation unit 11E based on the attitude and work status of the crane CR (West No. 1 CRW1, West No. 2 CRW2, West No. 3 CRW3, East No. 1 CRE1, East No. 2 CRE2, East No. 3 CRE3) calculated by the attitude work status calculation unit 11D is displayed in the center of the display screen of the terminal device 12. Therefore, by looking at the display screen of the terminal device 12, the user of the terminal device 12 can clearly grasp the lifting work status of the crane CR as if they were monitoring the crane CR from above.

[0021] In the example shown in FIG. 3 , when information indicating the swinging and / or hoisting operations of the cranes CR (West No. 1 CRW1, West No. 2 CRW2, West No. 3 CRW3, East No. 1 CRE1, East No. 2 CRE2, and East No. 3 CRE3) is acquired by the operation information acquisition unit 11A, the posture and work status calculation unit 11D calculates in real time the posture and work status of the crane CR performing the swinging and / or hoisting operations based on the information indicating the swinging and / or hoisting operations of the crane CR acquired by the operation information acquisition unit 11A. The display image generation unit 11E generates in real time an animated image of the crane CR performing the swinging and / or hoisting operations based on the posture and work status of the crane CR performing the swinging and / or hoisting operations calculated by the posture and work status calculation unit 11D. The display unit 12A of the terminal device 12 displays in real time the animated image of the crane CR performing the swinging and / or hoisting operations generated by the display image generation unit 11E. In another example, an animation image of the crane CR performing a swinging operation and / or a hoisting operation generated by the display image generation unit 11E may be stored in the memory unit 11G. In this example, the display unit 12A of the terminal device 12 can display the animation image of the crane CR performing a swinging operation and / or a hoisting operation stored in the memory unit 11G.

[0022] In the example shown in FIG. 3, the posture work status calculation unit 11D calculates in real time the posture and work status of the crane CR relative to the building BD based on the operation information of the cranes CR (West No. 1 CRW1, West No. 2 CRW2, West No. 3 CRW3, East No. 1 CRE1, East No. 2 CRE2, East No. 3 CRE3) acquired by the operation information acquisition unit 11A and the design data of the building BD. The display image generation unit 11E generates in real time an animated image of the crane CR including the building BD based on the posture and work status of the crane CR relative to the building BD calculated by the posture work status calculation unit 11D. The display unit 12A of the terminal device 12 displays in real time the animated image of the crane CR including the building BD generated by the display image generation unit 11E. In detail, the operation information of crane CR (west No. 2 CRW2) acquired by the operation information acquisition unit 11A includes coordinate information of the hook of crane CR (west No. 2 CRW2). The posture work status calculation unit 11D calculates the trajectory of the hook of crane CR (west No. 2 CRW2) relative to building BD based on the coordinate information of the hook of crane CR (west No. 2 CRW2) acquired by the operation information acquisition unit 11A and the design data of building BD. The display image generation unit 11E generates an image showing the trajectory of the hook of crane CR (west No. 2 CRW2) based on the trajectory of the hook of crane CR (west No. 2 CRW2) relative to building BD calculated by the posture work status calculation unit 11D. The display unit 12A of the terminal device 12 displays the image showing the trajectory of the hook of crane CR (west No. 2 CRW2) generated by the display image generation unit 11E, superimposed on an animated image of crane CR (west No. 2 CRW2) including building BD.

[0023] In detail, in the example shown in Figure 3, the operation information of the cranes CR acquired by the operation information acquisition unit 11A includes operation information of West No. 1 CRW1, operation information of West No. 2 CRW2, operation information of West No. 3 CRW3, operation information of East No. 1 CRE1, operation information of East No. 2 CRE2, and operation information of East No. 3 CRE3. Based on the operation information of West Unit 1 CRW1, West Unit 2 CRW2, West Unit 3 CRW3, East Unit 1 CRE1, East Unit 2 CRE2 and East Unit 3 CRE3 acquired by the operation information acquisition unit 11A and the design data of building BD, the posture and work status calculation unit 11D calculates the posture and work status of West Unit 1 CRW1, West Unit 2 CRW2, West Unit 3 CRW3, East Unit 1 CRE1, East Unit 2 CRE2 and East Unit 3 CRE3 relative to building BD, and the trajectories of the hooks of West Unit 1 CRW1, West Unit 2 CRW2, West Unit 3 CRW3, East Unit 1 CRE1, East Unit 2 CRE2 and East Unit 3 CRE3 relative to building BD. The display image generation unit 11E generates an animated image of West Unit 1 CRW1, West Unit 2 CRW2, West Unit 3 CRW3, East Unit 1 CRE1, East Unit 2 CRE2 and East Unit 3 CRE3 including the building BD based on the posture and work status of West Unit 1 CRW1, West Unit 2 CRW2, West Unit 3 CRW3, East Unit 1 CRE1, East Unit 2 CRE2 and East Unit 3 CRE3 relative to the building BD calculated by the posture and work status calculation unit 11D.

The operation unit 12B of the terminal device 12 accepts a selection operation by the user of the terminal device 12 (an operation to select the west No. 2 machine CRW2).

[0027] FIG. 4 is a flowchart illustrating an example of processing executed in the crane lifting monitoring system 1 of the first embodiment. In the example shown in FIG. 4, in step S11, the operation information acquisition unit 11A acquires operation information of the crane CR collected by the data collection unit CR5 installed in the crane CR. Next, in step S12, the posture and work status calculation unit 11D calculates the posture and work status of the crane CR based on the operation information of the crane CR acquired in step S11. Next, in step S13, the display image generation unit 11E generates an animated image of the crane CR that changes over time based on the posture and work status of the crane CR calculated in step S12, and corresponds to an image of the crane CR taken from above the crane CR. Next, in step S14, the display unit 12A of the terminal device 12 displays the animation image of the crane CR generated in step S13.

[0028] [Second embodiment] A second embodiment of the crane lifting monitoring system, crane lifting monitoring method, and program of the present invention will be described below. Except for the points described below, the crane lifting monitoring system 1 of the second embodiment is configured similarly to the crane lifting monitoring system 1 of the first embodiment described above. Therefore, the crane lifting monitoring system 1 of the second embodiment can achieve the same effects as the crane lifting monitoring system 1 of the first embodiment described above, except for the points described below.

[0029] As described above, the crane lifting monitoring system 1 of the first embodiment does not have the function of monitoring the status of the lifting work of the crane CR or of scheduling the lifting work of the crane CR, but the crane lifting monitoring system 1 of the second embodiment does have the function of scheduling the lifting work of the crane CR. In the crane lifting monitoring system 1 of the second embodiment, the number of pieces actually lifted in the previous construction cycle is reflected as the number of pieces planned to be lifted for that day. By linking the lifting monitoring server 11 and the schedule management system 13, the schedule management information acquisition unit 11C of the lifting monitoring server 11 acquires the schedule management information of the crane CR managed by the schedule management system 13 (name of material planned to be installed, planned installation position, planned work time).

[0030] In the crane lifting monitoring system 1 of the first embodiment, the input unit CR6 of the crane CR accepts inputs such as the name of the lifting material and the floor number of the installation site by the crane operator via an interface such as a touch panel. In the crane lifting monitoring system 1 of the second embodiment, the input unit CR6 of the crane CR may have a voice input function, an image recognition function, etc. That is, the input unit CR6 may accept voice input of the name of the lifted material, the installation floor number, etc. from the crane operator, or the input unit CR6 may identify the name of the lifted material by recognizing an image of the lifted material. In addition, the analysis unit 11F may predict failures by analyzing various sensor information (e.g., information from a temperature sensor, a load cell, a vibration sensor, etc.).

[0031] The crane lifting monitoring system 1 of the second embodiment may also link data with external systems other than the data collection unit CR5 and input unit CR6 of the crane CR. For example, the crane lifting monitoring system 1 may acquire data from a vehicle delivery schedule management system, a delivery vehicle GPS system, a steel frame fabrication component information system, etc., or may output data collected and analyzed within the crane lifting monitoring system 1 to an external system for use (for example, component installation position information may be output and used in a framework progress management system).

[0032] The crane lifting monitoring system 1 of the second embodiment may be provided with a function of predicting failures / preventing collisions of the crane CR by AI analysis of crane operation information, such as the output signal of the sensor CR4 of the crane CR.

[0033] The crane lifting monitoring system 1 of the first and second embodiments makes it possible to grasp the construction status without going to the site, even at super-high-rise construction sites where visibility to the construction floors is poor or at large construction sites where multiple cranes are used. Furthermore, because the system can automatically analyze and display lifting work in real time, it can significantly reduce the amount of work and man-hours required compared to conventional methods that involve manually recording and compiling actual results. Furthermore, it becomes possible to collect detailed data, such as load values ​​and wind speeds, in real time, which are difficult to grasp using conventional methods. In other words, it is possible to promote efficient, automated, and real-time understanding of the construction status. The crane lifting monitoring system 1 of the first and second embodiments allows for multifaceted analysis of lifting time, such as by component, by installation position, by crane, and the influence of wind speed, making it possible to identify which task has a problem and what the cause is earlier than with conventional methods and use this information to improve plans. Furthermore, crane failure information (operation information) can be checked remotely, allowing for early and remote response in the event of a failure. By using various accumulated information as learning data for AI failure prediction, failures can be prevented before they occur. Furthermore, by introducing a cloud server, construction companies can utilize and centrally manage accumulated data company-wide.

[0034] Although the embodiments of the present invention have been described in detail above with reference to the drawings, the specific configurations are not limited to these embodiments and examples, and appropriate modifications can be made without departing from the spirit of the present invention. The configurations described in the above-described embodiments and examples may be combined.

[0035] Note that all or part of the functions of each unit of the crane lifting monitoring system 1 in the above-described embodiment may be realized by recording a program for realizing these functions on a computer-readable recording medium, and reading and executing the program recorded on the recording medium into a computer system. Note that the term "computer system" here includes hardware such as an OS and peripheral devices. Furthermore, "computer-readable recording media" refers to portable media such as flexible disks, optical magnetic disks, ROMs, and CD-ROMs, as well as storage units such as hard disks built into computer systems. Furthermore, "computer-readable recording media" may also include devices that dynamically store programs for a short period of time, such as communication lines when transmitting programs over networks like the Internet or communication lines like telephone lines, or devices that store programs for a fixed period of time, such as volatile memory within computer systems that serve as servers or clients in such cases. Furthermore, the above-mentioned programs may be programs that realize some of the aforementioned functions, or may be programs that can realize the aforementioned functions in combination with programs already stored in the computer system.
