Description

  The present invention relates to a technology for inspecting an elevator using a flying object.

  In general, an elevator is provided with an earthquake control operation device that stops the elevator operation of the car when it detects an earthquake shake. This seismic control operation system stops the car at the nearest floor when the seismograph installed in the machine room or the tower senses a constant shake, opens the door of the car, and stops at the stop floor. Evacuate the user. This action ensures the safety of the user.

  The seismic motion sensed by the seismic control and operation device includes initial tremor and major motion. The earthquake control operation device automatically restores the elevator car after the elapse of a predetermined time when only the initial fine movement is detected. On the other hand, when the main movement of strong shaking is detected, after stopping the elevator operation of the car, the elevator operation of the car is performed until the on-site inspection for restoration is performed by the maintenance staff with specialized skills. Do not restore

  For this reason, when the earthquake control operation device detects a main motion, maintenance personnel need to go to the site and visually check and inspect the damage or damage of the equipment in the hoistway. In this case, the maintenance worker is able to move up and down the car normally, including the presence or absence of the main rope, the presence or absence of the tail cord, the presence or absence of inclination of the guide rail, and whether the car is not removed from the guide rail. Inspect for possible damage.

  On the other hand, while the elevators are stopped, residents of higher floors may lose mobility and may be left on higher floors. For this reason, maintenance personnel need to carry out an inspection as soon as possible and restore the elevator operation of the car.

  However, such an inspection requires a considerable amount of time, and particularly in the case of a high-rise elevator with a long hoistway, a great deal of time is required for the confirmation operation.

  Although the above mentions the time of an emergency when an earthquake occurs, the same can be said for regular / irregular maintenance work. When performing maintenance work, confirmation work is performed as in the case of the above-mentioned earthquake occurrence, but it is necessary to stop the elevator car to be checked during that time. Therefore, when maintenance work is performed, the resident of the high floor loses the moving means in the case of a single elevator configuration, and the moving means is insufficient even in the case of a plurality of elevators. In any case, it is inconvenient for the resident while the maintenance work is being performed, and it is desirable that the maintenance work be completed promptly.

  Under such circumstances, in recent years, research and development have been conducted on inspection devices used for inspection in the hoistway in a state where the elevator car can not be moved, and has been put into practical use.

  As a check device used when a maintenance worker checks, for example, in order for the maintenance worker to confirm the condition of the equipment in the hoistway, ascend and descend while avoiding obstacles in the hoistway and photographing the equipment in the hoistway A technology for performing an inspection operation using a flying object is disclosed (for example, Patent Document 1). According to this technique, the maintenance staff first introduces the above-described inspection device (aircraft) into the hoistway. Next, the distance measuring means grasps the distance between the inspection device and the equipment in the hoistway, moves it up with the flight means while avoiding obstacles, and the maintenance worker takes an image of the equipment in the hoistway photographed by the photographing means By checking, the device status can be checked.

  When flying the inspection device mentioned above in the hoistway in which a plurality of elevators are housed adjacent to each other, there is no partition between the elevator to be inspected and the adjacent elevator, or the partition is made of wire mesh etc. As a result, the in-flight inspection system is affected by the crosswind generated by the travel of the adjacent elevator.

  Due to the crosswind, there is a risk that the in-flight inspection device wanders and collides with equipment in the hoistway, damaging equipment in the hoistway, or losing balance and crashing.

  The present invention has been made to solve such problems, and its technical problem is to provide a technology capable of reducing the risk of inspection due to crosswind generated by the traveling of an adjacent elevator.

  In order to solve the above-mentioned problems, a representative elevator inspection system according to the present invention is an elevator inspection system for inspecting the inside of the hoistway of any one of a plurality of elevators installed adjacent to each other. And receives information from the aircraft for acquiring information in the hoistway by raising or lowering the hoistway of the non-operating elevator, and position information indicating the position of the aircraft in the height direction from the aircraft. A position information receiving unit; and a traveling information receiving unit for receiving traveling information including information on which floor of an adjacent elevator operating in the hoistway adjacent to the hoistway of the non-operating elevator, the floor being traveled; A determination unit that determines whether the adjacent elevator travels beside the flying object based on the position information and the travel information, and the adjacent elevator travels along the flight object by the determination unit To be judged If an instruction to instruction information to take the saving action to reduce the effect of cross wind accompanying the travel of the neighboring elevator, and a control signal transmission unit to be transmitted to the aircraft.

According to the present invention, when an adjacent elevator travels beside the aircraft, the aircraft can take action to reduce the influence of crosswind. Thus, it is possible to reduce the risk of flying or crashing the aircraft.
Problems, configurations, and effects other than those described above will be clarified by the description of the embodiments below.

It is a flowchart which shows the operation example of embodiment. It is the figure which put together the content of retraction | saving control operation of the flying body of embodiment. It is the figure which showed the other evacuation operation of the flight object of an embodiment.

  In the elevator inspection system according to the present embodiment, a flying object having an imaging sensor flies in the elevator shaft of an elevator to be inspected, and transmits an internal image to a terminal device (elevation inspection device) owned by a maintenance worker. The maintenance worker checks the video transmitted from the flying object on the display unit of the terminal device and operates the operation of the flying object via the terminal device.

  Further, in the elevator inspection system according to the present embodiment, the terminal device obtains traveling information of the adjacent elevator from the monitoring center, combines the traveling information of the adjacent elevator obtained from the monitoring center and the position information of the flying object, and the adjacent elevator Determine if you will travel beside the aircraft. When the adjacent elevator travels beside the aircraft, the aircraft retracts to a position away from the adjacent elevator in preparation for a crosswind before the adjacent elevator passes by the aircraft. In addition, the elevator inspection system stops by the adjacent elevator changing or hovering up / down speed according to the traveling speed passing by the side of the aircraft.

  Hereinafter, an embodiment of an elevator inspection system according to the present embodiment will be described based on the drawings.

  FIG. 1 is a view showing the main part of a configuration in which a plurality of elevators are delivered adjacent to each other, and illustrates a configuration in which two elevators, elevator 1 and elevator 2, are housed adjacent to each other. . The elevators 1 and 2 move in the hoistway 3 in which the car 4 is installed in the building, and move up and down between the landings 5 installed on each floor. A pit 6 is provided in the lower part of the hoistway 3, and a machine room 7 is provided in the upper part of the hoistway 3.

  The car 4 ascends and descends along a car guide rail 8 erected on a beam of the hoistway 3. The counterweight 11 attached to the car 4 by the main rope 10 via the hoisting machine 9 installed in the machine room 7 is similarly a counterweight installed upright on the beam of the hoistway 3 Ascend and descend along the guide rails 12. Further, in the machine room 7, there is installed a control panel 13 for grasping the stop floor of the car 4 of the elevators 1 and 2 and the floor height information of each floor and controlling the elevation operation of the car 4. The information acquired by the control panel 13 is sequentially or periodically transmitted to the monitoring server 170 described later via the wide area network.

  A main rope 10 is hung on a hoisting machine 9 for raising and lowering the car 4, one end of the main rope 10 is attached to the car 4, and the other end is attached to a counterweight 11. In addition, a main body of the governor not shown is provided in the machine room 7, and a governor rope not shown is provided for the pulley in the machine room 7 in the governor and the pulley installed on the pit 6 It is hung and extends in the height direction in the hoistway 3.

  The car 4 of the elevators 1 and 2 is raised and lowered by driving the hoisting machine 9, but the landing door 14 provided at the landing of each floor serves as a lift door for the car 4. The landing door 14 engages with the car door 15 of the car 4 when the car 4 lands, and allows the user to get on and off the car 4 by opening and closing.

  Further, the hoistways 3 of the elevator 1 and the elevator 2 are partitioned by a wire mesh 16 in the whole range or in part for safety in maintenance work. When the partition member is the wire mesh 16 as described above, when one elevator travels and passes, the crosswind enters the hoistway 3 on the other elevator side from the gap of the mesh of the wire mesh 16.

  A maintenance worker with specialized technology stops the elevator to be checked as a non-operating elevator at the time of regular or irregular check work, opens the landing door 14 by the external opening means, and checks the inside of the hoistway 3. For example, when a strong shaking earthquake occurs and the elevator 1 is stopped and becomes a non-operating elevator, the maintenance worker also performs inspection work for restoration on site. At the time of inspection work such as these, it becomes possible for maintenance personnel to open the landing door 14 and allow an aircraft, which is one of the configurations of the elevator inspection system described later, to enter into the hoistway 3.

  This aircraft is the floor of pit 6 in hoistway 3 so that maintenance personnel can start inspection immediately after a strong earthquake occurs and elevators 1 and 2 stop without bringing the aircraft. Alternatively, it may be permanently installed on the car 4 or on both cars.

  FIG. 2 is a view showing a configuration example of the elevator inspection system of the present embodiment. The elevator inspection system 500 includes a monitoring server 170 installed in the monitoring center 17, a flying object 18 for flying the inside of the hoistway 3, and a terminal device 19 for operating the flying object 18 held by maintenance personnel. Have. The monitoring server 170 and the terminal device 19 perform data communication with each other via the network 600 in which wired / wireless communication means are mixed. The terminal device 19 and the flying object 18 perform data communication with each other via wireless communication. There is no limitation on wired / wireless communication means or wireless communication standards.

  In the present embodiment, the elevator 1 is an elevator to be checked, and the elevator 2 is an adjacent elevator currently in operation. Further, in FIG. 2, the elevator 1 is in a state in which the car stops at the 30th floor, and is in a state in which the inside of the hoistway 3 is inspected by raising the flying body 18 from the lowest floor. Further, it is assumed that the adjacent elevator 2 is rising from the first floor to the 30th floor.

  The monitoring server 170 has a function of transmitting, to the terminal device 19, traveling information of an elevator, which will be described later, for the adjacent elevator 2 always in real time. The monitoring server 170 may be replaced by the control board 13 having the above-mentioned elevator status information.

  The flying object 18 is composed of, for example, a multicopter such as a drone. The flying object 18 has an imaging unit 181 such as an omnidirectional camera for imaging the inside of the hoistway, and an altimeter 182 configured with a barometric altimeter, a laser distance measuring sensor, and the like. The flying object 18 also has a communication unit 183 that communicates with an external device by wireless communication or the like. In addition to these, the flying body 18 has a horizontal position grasping unit 184 that grasps the horizontal position in the hoistway 3 at the time of flight. The horizontal position grasping unit 184 has a camera for imaging in the horizontal direction and the periphery of the flying object 18 and / or a distance sensor for measuring the distance in the horizontal direction and the periphery, or both devices. Based on the data obtained from these devices of the horizontal position grasping part 184, the aircraft 18 grasps the horizontal position by itself, and using the known technology, the aircraft 18 avoids an obstacle by itself or the hoistway 3 Avoid contact with internal sidewalls.

  The flying object 18 can grasp its own height and horizontal position by having the photographing part 181, the altimeter 182, the communication part 183, and the horizontal position grasping part 184, and has an autonomous flight function, and ascends and descends. Photography of each device in the road 3 is possible. In addition to these, the flight 18 is equipped with a light that illuminates the interior of the hoistway 3 and an orientation sensor that determines which direction the flight 18 is facing with respect to the north.

  The terminal device 19 is a device having an arithmetic function such as a personal computer and a communication function. The terminal device 19 transmits and receives data to and from the monitoring server 170 and the flying object 18, and based on the traveling information of the elevator and the position information of the flying object 18, the control instruction information (hereinafter referred to as alert signal) Transmit and control the flight of the aircraft 18.

  FIG. 3 is a diagram showing an example of the hardware configuration of the terminal device 19. The terminal device 19 includes a controller 101, and peripheral devices such as an HDD 120 (HDD: Hard Disk Drive), an input device 121, and an output device 123.

  The controller 101 controls each piece of hardware operating inside the terminal device 19. The controller 101 has the following configuration.

  The CPU 102 (CPU: Central Processing Unit) is a processing device that develops a program stored in the ROM 104 (ROM: Read only memory) or the HDD 120 into the RAM 103 (RAM: Random access memory) and executes calculation. The CPU 102 centrally controls each piece of hardware in the controller 101 by executing a program. The RAM 103 is a volatile memory and is a work memory when the CPU 102 processes. The RAM 103 temporarily stores necessary data while the CPU 102 executes the program.

  The ROM 104 is a non-volatile memory, and stores a BIOS (Basic Input / Output System) executed by the CPU 102 when the terminal device 19 is activated, and firmware. The storage I / F 105 (I / F: Interface) is an interface for controlling writing and reading of data with the HDD 120.

  A network I / F 106 is an interface board responsible for control of data communication performed with an external device.

  The input I / F 107 is an interface that controls input and output of signals with the input device 121. The output I / F 108 receives an instruction from the CPU 102 and causes the output device 123 to draw an image.

  The HDD 120 is an auxiliary storage device that stores data in a non-volatile manner. The HDD 120 stores programs executed by the CPU 102 for calculation and control data. In the present embodiment, a program providing each function described later is introduced in advance.

  The input device 121 is, for example, a keyboard or a mouse, but may be a control lever group suitable for steering the flying object 18 or the like. The output device 123 is a flat monitor or a display. When the terminal device 19 is a tablet, a smartphone, or the like, the input device 121 and the output device 123 may constitute a touch panel display.

  FIG. 4 is a block diagram showing a configuration example of the terminal device 19. The terminal device 19 includes a display unit 190, a traveling information receiving unit 191, a position information receiving unit 192, a floor calculating unit 193, a determining unit 194, a control signal transmitting unit 195, and an operation unit 196. The display unit 190 displays the real-time image captured by the imaging unit 181 of the flying object 18 received via the network I / F 106. The operation unit 196 is a unit for the operator to maneuver the flying body 18, generates an operation control code associated with each flight operation of the flight body 18 according to the operation of the operator, and transmits a control signal Pass the code to section 195. Thereby, the flying object 18 moves in the front, rear, left, right, up and down directions according to the operation control code, and performs acceleration / deceleration, hovering stop, and the like. The other travel information reception unit 191, the position information reception unit 192, the floor calculation unit 193, the determination unit 194, and the control signal transmission unit 195 will be described again using a flowchart to be described later.

  FIG. 5 is a diagram showing an example of a data configuration of traveling information of the elevators 1 and 2 stored by the monitoring server 170 in the monitoring center 17. As shown in FIG. In the travel information of the elevators 1 and 2, status information 171 indicating which one of the "stop status", "ascending operation" and "descent operation" the car 4 is in, and at which floor the car 4 is currently stopped or Position information 172 indicating whether or not moving is included. In addition, elevator movement information includes car movement information 173 indicating from which floor to which floor the car 4 is to move, speed information 174 of the car 4, and a floor indicating the height of one floor. High information 175 is included. The monitoring server 170 constantly receives these pieces of information from the control panel 13 and manages and stores traveling information of the elevators 1 and 2.

  FIG. 6 is a flow chart showing an operation example for reducing the influence of crosswind due to the adjacent elevator 2 passing by the side of the flying object 18 while the elevator inspection system is inspecting the elevator 1. The following description will be given on the assumption that the flying object 18 sequentially checks from the first floor to the 30th floor, which is the lower floor of the elevator 1 shown in FIG.

  In step S001, the maintenance worker first activates the flying body 18 and the terminal device 19 at the landing 5 on the first floor of the elevator 1. The maintenance staff opens the landing door 14 from the landing 5 on the first floor and places the flying object 18 on the floor in the hoistway 3. Further, in the mounted state, in which of the front, rear, left, and right the flying object 18 is positioned with respect to the adjacent elevator 2 and the direction indicated by the direction sensor attached to the flying object 18 are associated with each other. Register on By these registrations, it is possible to grasp which of the front, rear, left and right of the flying object 18 is the adjacent elevator 2 from the reading value of the azimuth sensor even during the flight, and retreating into which of the front, rear, left or right The direction can be derived. Then, the maintenance personnel fly the flying object 18 and start inspection (S001). The flying object 18 performs inspection while photographing the inside of the hoistway 3 by the photographing unit 181.

  At the time of inspection, the flying object 18 descends after rising to below the car 4. As a result, the maintenance worker can perform inspection while visually recognizing the image of the equipment of the hoistway 3 captured by the flying object 18. Here, the operation of step S001 will be described as being performed while continuing the contents shown in step S002 and thereafter.

  The traveling information receiving unit 191 of the terminal device 19 receives the state information 171 of the car 4, the position information 172, the car movement information 173, the speed information 174, and the floor height information 175 from the monitoring server 170 of the monitoring center 17 ( S002).

  The position information receiving unit 192 of the terminal device 19 receives the flying height obtained from the altimeter 182 included in the flying object 18, and receives the direction in which the flying object 18 faces, which is detected by the direction sensor (S003).

  The floor calculation unit 193 of the terminal device 19 uses the floor height information 175 obtained in step S002 and the flight height of the flying object 18 obtained in step S003 to determine the current floor position of which floor the flying object 18 is on. It calculates (S004).

  The determination unit 194 of the terminal device 19 determines whether the adjacent elevator 2 passes by the side of the flying object 18 based on the travel information of the adjacent elevator 2 obtained from the monitoring server 170 and the calculated current floor position. Determine and predict. When passing, the determination unit 194 determines which of the upper and lower directions the vehicle 18 passes from the side and derives the passing speed of the elevator 2. The control signal transmission unit 195 transmits an alert signal according to the determination result of the determination unit 194 to the aircraft 18.

  In the state information 171 of the adjacent elevator 2, when the car 4 is stopped (S 005: Yes), the determination unit 194 delivers a value indicating continuation of inspection to the control signal transmission unit 195. The control signal transmission unit 195 transmits an alert signal indicating continuation of inspection to the flying object 18 (S101). The flying object 18 that has received the alert signal indicating the continuation of inspection performs only flight control according to the operation of the operation unit 196 without taking an evacuation action.

  When the car 4 is in operation (S 005: No), the determination unit 194 compares the car movement information 173 with the floor position of the aircraft 18. As a result, when the adjacent elevator 2 does not pass by the side of the flying object 18 (S006: Yes), a value indicating continuation of inspection is handed over to the control signal transmission unit 195. Then, the control signal transmission unit 195 transmits an alert signal indicating continuation of inspection to the flying object 18 (S102). For example, when the car 4 of the elevator 2 is stopped or the car 4 moves in a direction away from the floor currently being flew on the second to third floors prior to the current flight of the flying body 18. In this case, the car 4 of the elevator 2 does not pass by the side of the flying object 18. In step S 006, the determination unit 194 makes a determination based on the position and movement of the aircraft 18 and the car 4 as described above.

  When the car 4 passes by the side of the flying object 18 (S006: No), the judging unit 194 determines that the car 4 of the adjacent elevator 2 is 120 m / side of the flying object 18 based on the position information 172 and the speed information 174. It is determined whether it passes by less than min (S007). At this time, in consideration of acceleration / deceleration of the car 4, the determination unit 194 obtains the speed at the time of passing the side of the flying object 18. In addition, the value of 120 m / min is a threshold value defined beforehand, and setting change is possible. When passing at a speed of 120 m / min or more (S007: No), the determination unit 194 separates from the adjacent vehicle, and hands over to the control signal transmission unit 195 a value indicating that the flying object 18 flies. The control signal transmission unit 195 transmits an alert signal indicating that the above operation is to be performed to the flying object 18 (S104). The alert signal includes numerical information as to how much travel in which direction. When the flight body 18 receives this signal, it flies away from the adjacent unit and flies for hovering before the car 4 of the adjacent elevator 2 passes. The flying object 18 moves away from the adjacent elevator 2 while avoiding contact with the side wall inside the hoistway 3 by using the function of the horizontal position grasping part 184. The flying object 18 maintains this state for a specified time determined not to be affected by the crosswind, and restarts the inspection after passing.

  On the other hand, when passing at less than 120 m / min (S007: No), the determination unit 194 further determines whether the car 4 of the adjacent elevator 2 passes downward from above or passes upward from below It determines (S008). When passing from above (S 008: Yes), the determination unit 194 separates from the adjacent aircraft, and further reduces the moving speed of the flying object 18 to half of the current speed and indicates a value indicating that the inspection is continued Hand over to 195. The control signal transmission unit 195 transmits an alert signal indicating that the above operation is to be performed to the flying object 18 (S103). When this signal is received, the flying object 18 separates from the adjacent car and continues the inspection while flying at half the current speed before the car 4 of the adjacent elevator 2 passes. The flying object 18 maintains this state for a predetermined time determined not to be affected by the crosswind.

  Further, the flying body 18 of the present embodiment is more likely to lose balance if it receives an upward wind from below than it receives a downward wind from above. Therefore, when the adjacent elevator 2 passes upward from the bottom (S008: No), since an ascending air flow is generated, the process proceeds to step S104, and the flying object 18 is controlled to take a safer evacuation action. That is, the flying object 18 is controlled to separate from the adjacent aircraft and to hover further.

  The operations of S002 to S104 are performed until the flight object 18 lands on the first floor, that is, until the inspection work is completed (S111: No loop), and when the inspection work is completed (S111: Yes) Become.

  FIG. 7 is a diagram in which the contents of the above-mentioned evacuation action are summarized and listed. Data of contents shown in FIG. 7 are stored in advance in the HDD 120 of the terminal device 19. In addition, parameters such as a threshold value such as 120 m / min and the value of the deceleration speed (1/2 in this example from the current speed) can be changed. The determination unit 194 determines whether the conditions of the conditions 71 to 74 shown in FIG. 7 are met, and the control signal transmission unit 195 transmits a corresponding alert signal (alert 75 to the flying object). Further, the determination unit 194 first performs the determination process on the condition 71, and then performs the determination process in the order of the condition 72, the condition 73, and the condition 74. The condition 71 is determined by referring to the data of the state information 171 shown in FIG. 5, and the condition 72 is determined by evaluating whether the flying object 18 is positioned within the range of the moving floor of the car movement information 173. Ru. The condition 73 is determined by referring to the position information 172 and the velocity information 174, and the condition 74 is determined by referring to the state information 171.

  Further, in the present embodiment, when any one of the conditions is met, the subsequent condition determination is not performed. For example, when it is determined that the vehicle is stopped under the condition 71, it is determined whether the vehicle passes the side (condition 72), the speed determination (condition 73), and the upper / lower passage direction determination (condition 74). Even if done, these are meaningless and unnecessary determination processes. If it is determined that the vehicle does not pass sideways under the condition 72, even if the speed determination (condition 73) and the upper / lower passing direction determination (condition 74) are performed, these become unnecessary determination processing. Therefore, the determination unit 194 performs the determination in order from the condition 71, and when it matches, immediately exits the determination processing and outputs the corresponding alert 75. By doing this, the processing time of the determination can be shortened.

  FIG. 8 is a diagram for explaining another evacuation action. Here, partition plate members 16A for separating the elevators 1 and the respective hoistways of the elevators 2 are provided at regular intervals, and a space 16B for ventilation is provided between the partition plate members 16A. In the case of such a partition, the effect of crosswind can be suppressed more than moving away from the adjacent elevator if moving so as to move toward and move closer to the partition plate 16A. The determination unit 194 acquires the positions and dimensions in the height direction of the partition plate material 16A and the space 16B, for example, from the monitoring server 170, and compares them with the flight height obtained in step S003 of FIG. As a result, the flying body 18 can also perform an evacuation action approaching the partition plate 16A.

  According to the above procedure, the flying object 18 can fly to avoid the crosswind accompanying the passing of the adjacent elevator 2 before the adjacent elevator 2 passes by the side of the flying object 18. In addition, depending on the speed at which the adjacent elevator 2 passes by the side of the flying object 18, the rising and lowering speeds of the flying object 18 can be changed, and the hovering state or the like can be stopped. As a result, the influence on the crosswind caused by the adjacent elevator 2 can be reduced, and the risk of the flying object 18 fluttering or crashing can be reduced.

  In addition, this embodiment is applicable also when it is comprised by three or more elevators and it makes an inspection object the elevator which both adjacent sides are operate | moving. In this case, when the elevators on both sides pass at the same time, the flying object 18 uses the function of the horizontal position grasping unit 184 to perform the evacuation action so as to hover at the central portion.

  In the present embodiment, the determination unit 194 determines which withdrawal behavior to perform, but the control signal transmission unit 195 may determine the withdrawal behavior based on the determination result of the determination unit 194. In addition, although the evacuation behavior of this embodiment is assumed to be away from the adjacent elevator and to decelerate or stop hovering, it may be an evacuation behavior only to separate from the adjacent elevator, and is an evacuation behavior only to decelerate or hover stop. May be

  According to this embodiment, when the adjacent elevator travels beside the aircraft, the aircraft can fly away from the adjacent elevator before the adjacent elevator passes by the aircraft. . Therefore, it is possible to reduce the influence on the cross wind and to reduce the risk of flying and falling of the flying object.

  In addition, the adjacent elevators can change the speed at which the aircraft is moving up and down according to the traveling speed passing by the side of the aircraft. This can reduce the risk of wandering and crashing. In addition, when it is presumed that the speed of the adjacent elevator is high and the crosswind is large, the risk of instability and crash can be further reduced by stopping the rise and fall of the flight body and hovering and preparing for the crosswind.

  As described above in detail, the present embodiment can reduce the risk of inspection due to crosswind generated by traveling of the adjacent elevator.
