Description

This invention relates to a crane operation support system, a layout unit , and a program . Patent Document 1 discloses a technology for inspecting a crane by flying a drone around it. The drone is equipped with a magnetic compass sensor, and the measurements from this sensor are used for flight control. International Publication No. 2020/218433 This is a drawing of a crane operation support system.This is a perspective view of the station equipment and the aircraft.This is a block diagram of the aircraft and its support equipment.This is a diagram of a crane operation system in a modified example.This is a diagram of the main part of the crane in a modified crane work system. The following describes each embodiment in detail with reference to the drawings. <1. Overview of the Crane Operation Support System> Figure 1 shows a crane operation support system. The crane work support system comprises a steel plate 10, a station device 20, a crane 30, a magnetic sensor 50, an aircraft 60, and a work support device 80. Although the aircraft 60, station device 20, and work support device 80 are significantly smaller than the crane 30, they are depicted larger in Figure 1 for illustrative purposes. Furthermore, although the thickness of the steel plate 10 is considerably smaller than the height of the crane 30, the steel plate 10 is depicted as thicker in Figure 1 for illustrative purposes. <2. Steel plates> The steel plates 10 are laid on the ground 2 at the work site for the purpose of protecting the ground at the work site and securing a work platform. The steel plates 10 are used as a work platform at the work site, the crane 30 travels on the steel plates 10, and workers perform their work on the steel plates 10. The steel plates 10 are made of a magnetic material. A magnetic material is a substance that exhibits ferromagnetism. The magnetic field around the steel plates 10, which are made of a magnetic material, is affected by the steel plates 10. For example, because the steel plates 10 disturb the magnetic field and geomagnetism around them, the magnetic field around the steel plates 10 is a change from the geomagnetism that would exist without the steel plates 10. On the other hand, non-magnetic materials do not disturb the magnetic field and geomagnetism around them. A non-magnetic material is a substance other than a magnetic material, and diamagnetic and paramagnetic materials are also non-magnetic materials. Copper, wood, and aluminum are non-magnetic materials. In the following, a magnetic field that is not the geomagnetism will be called an abnormal magnetic field, and a magnetic field disturbed from the geomagnetism will also be called an abnormal magnetic field. <3. Station Equipment> The station device 20 is a platform that supports the aircraft 60 from below when it is not flying, with the aircraft 60 separated upward from the steel plate 10. The station device 20 is also a platform on which the aircraft 60 takes off and lands. The station device 20 is movable on the steel plate 10 and its height is adjustable. As shown in Figure 2, the station device 20 comprises a station 21, a height adjuster 22, a trolley 23, and a magnetic sensor 24. The station 21 is attached to the height adjuster 22, particularly its upper end. The height adjuster 22, particularly its lower end, is attached to the trolley 23. Station 21 is a platform on which the aircraft 60 can be placed. The aircraft 60 is placed on Station 21 before flight. Station 21 is made of a non-magnetic material, particularly resin or aluminum. Therefore, Station 21 does not disturb the surrounding magnetic field and geomagnetic field. In the example shown in Figure 2, Station 21 is provided in a plate shape. However, the shape of Station 21 is not limited to a plate shape, as long as it can accommodate the aircraft 60. The height adjuster 22 is, for example, a lift having a telescopic rod that can extend and retract vertically, a hydraulic cylinder, an air cylinder, a jack, or a linkage mechanism. The height adjuster 22 extends upward and retracts downward using power from a prime mover (e.g., electric motor, internal combustion engine, steam engine, hydraulic equipment, or turbine), the elastic force of a spring, hydraulics, pneumatics, or human power. The height adjuster 22 raises and lowers the station 21 through its extension and retraction movement, and maintains the height of the station 21 by stopping the extension and retraction movement. In this way, the height adjuster 22 moves the station 21 vertically to adjust its height. The uppermost position in the lifting range of the station 21 by the height adjuster 22 is not particularly limited, but may be higher or lower than the height of the lower traveling body 31 described later. The trolley 23 is movable on the steel plate 10. The trolley 23 moves on the steel plate 10 using power from a prime mover (e.g., electric motor, internal combustion engine, steam engine, hydraulic equipment, o
