The casing 21 is a rectangular parallelepiped frame member made of steel, and fixes each of the motor 22, the speed reducer 23, the drum 24, and the mooring line length sensor 25 at predetermined positions. The motor 22 is connected to the control device 40 via a cable 26 capable of communicating electrical signals, and rotates in a first direction or a second direction opposite to the first direction in accordance with a control signal transmitted from the control device 40. To do. The speed reducer 23 is disposed between the motor 22 and the drum 24 and transmits the rotation of the motor 22 to the drum 24 while reducing the speed. The drum 24 unwinds the mooring line 11 in response to the motor 22 rotating in the first direction, and winds the mooring line 11 in response to the motor 22 rotating in the second direction.

  The detected portion 31 includes a plurality of magnets 311 and a movement range limiting member 312 when not in use. The detected portion 31 is engaged with a main mooring line 110 that is separated from the balloon 10 by about 6 m, for example. The plurality of magnets 311 are cylindrical members formed with through holes through which the mooring lines 11 penetrate, and in one example, are permanent magnets formed of neodymium. The height H of each of the plurality of magnets 311 is 2 mm or more and less than half the diameter of the main mooring line 110. When the diameter of the main mooring line 110 is 6 mm, the height H of each of the plurality of magnets 311 is 3 mm or less, and when the diameter of the main mooring line 110 is 8 mm, the height of each of the plurality of magnets 311 is H. Is 4 mm or less. If the height H of each of the plurality of magnets 311 is less than 2 mm, the magnet 311 may be damaged when each of the plurality of magnets 311 passes through the four-sided roller 14. Further, if the height H of each of the plurality of magnets 311 is larger than half of the diameter of the main mooring line 110, the flexibility of the main mooring line 110 in which the plurality of magnets 311 are arranged is reduced, and the plurality of magnets 311 are reduced. There is a risk that each of these will not easily pass through the four-sided roller 14. The movement range limiting member 312 is a string-like member having one end fixed by the first fixing portion 313 and the other end fixed by the second fixing portion 314, and the movement range of the plurality of magnets 311 is defined by the first fixing portion 313.

The proximity switch 321 is “closed” in response to the detection of the magnet 311 and causes a current to flow between the power supply voltage VDD and the ground GND. The photocoupler 322 outputs a storage signal to the control device 40 when the proximity switch 321 is “closed” and a current flows between the power supply voltage VDD and the ground GND. When the proximity switch 321 detects the magnet 311, that is, when the length of the mooring line 11 between the balloon 10 and the winding device 20 reaches a predetermined storage length, the first detection unit 32 stores the first detection unit 32.

(Balloon mooring process and balloon storage process by the mooring balloon according to the embodiment)
FIG. 6A is a flowchart of the balloon mooring process by the mooring balloon 1, and FIG. 6B is a flowchart of the balloon storing process by the mooring balloon 1. The balloon mooring process shown in FIG. 6 (a) and the balloon storage process shown in FIG. 6 (b) are mainly performed by the processing unit 50 based on the program stored in the storage unit 42 in advance. It is executed in cooperation with.

(Balloon mooring process with mooring balloon 1)
First, the instruction acquisition unit 51 acquires a balloon mooring instruction corresponding to a balloon mooring instruction signal input from the input unit 43 in response to an operation by an operator for mooring the balloon 10 at a predetermined altitude (S101). Next, the balloon raising / lowering instruction unit 52 outputs a control signal indicating an instruction to rotate the motor 22 in the first direction to the motor 22 in order to raise the balloon 10 (S102). The motor 22 rotates in the first direction in response to an input of a control signal indicating an instruction to rotate in the first direction, and the mooring line 11 is unwound from the drum 24 in response to the motor 22 rotating in the first direction. It is. In response to the mooring line 11 being unwound from the drum 24, the balloon 10 rises.

  Then, the unwinding stop instruction unit 53 issues an instruction to stop unwinding of the mooring line 11 when the altitude of the balloon 10 corresponding to the balloon altitude signal input from the mooring line length sensor 25 reaches a predetermined altitude. The unwinding stop instruction signal shown is output to the motor 22 (S103). When the unwinding stop instruction signal is input, the motor 22 stops unwinding the mooring line 11.

(Ball storage process by mooring balloon 1)
First, the instruction acquisition unit 51 acquires a balloon mooring instruction corresponding to a balloon storage instruction signal input from the input unit 43 in response to an operation by an operator for storing the balloon 10 (S201). Next, the balloon raising / lowering instruction unit 52 outputs a control signal indicating an instruction to rotate the motor 22 in the second direction to the motor 22 in order to lower the balloon 10 (S202). The motor 22 rotates in the second direction in response to an input of a control signal indicating an instruction to rotate in the second direction, and the mooring cable 11 is wound around the drum 24 in response to the motor 22 rotating in the second direction. It is done. In response to the mooring line 11 being wound on the drum 24, the balloon 10 descends and comes into close contact with the frame 131.

  Next, the winding stop instruction unit 54 determines whether or not an accommodation signal is input from the first detection unit 32 (S203). When it is determined that the storage signal is input from the first detection unit 32 (YES in S203), the winding stop instruction unit 54 outputs a winding stop instruction signal indicating an instruction to stop winding of the mooring cable 11 to the motor. 22 (S204). The motor 22 stops the winding of the mooring line 11 when the winding stop instruction signal is input.

  When it is determined that the storage signal is not input from the first detection unit 32 (S203—NO), the alarm signal output unit 55 determines whether an overwinding signal is input from the second detection unit 33. (S205). If it is determined that the overwinding signal is not input from the second detection unit 33 (S205—NO), the process returns to S203. Thereafter, it is determined that the storage signal is input from the first detection unit 32 (S203—YES), or it is determined that the overwinding signal is input from the second detection unit 33 (S205—YES). Until then, the processing of S203 and S205 is repeated.

  When it is determined that an overwinding signal is input from the second detection unit 33 (YES in S205), the winding stop instruction unit 54 indicates a winding stop instruction indicating an instruction to stop winding of the mooring line 11. A signal is output to the motor 22 (S206). And the warning signal output part 55 outputs the overwinding warning signal which shows the warning that the winding device 20 has wound up the mooring cable 11 too much to the output part 44 (S207). When the overwinding alarm signal is input, the output unit 44 displays an image indicating that the winding device 20 is winding the mooring cable 11 too much.

(Operational effect of the mooring balloon according to the embodiment)
In the moored balloon 1, the storage detection sensor 30 detects that the balloon 10 has been stored in the storage position, so that the balloon 10 can be stored in the predetermined storage position. Specifically, the mooring balloon 1 detects the mooring line when the storage detection sensor 30 detects that the length of the mooring line 11 between the balloon 10 and the winding device 20 has reached a predetermined storage length. 11 is stopped, so that the balloon 10 can be stored in a predetermined storage position in close contact with the frame 131. In the mooring balloon 1, the balloon 10 and the pedestal 131 are integrated by the frictional force generated in the contact portion where the balloon 10 and the pedestal 131 are in close contact with each other when the balloon 10 is accommodated in the storage position. Wind resistance on the ground is improved.

  In the mooring balloon 1, when the balloon 10 is stored, the winding of the mooring line 11 by the winding device 20 is stopped according to the detection of the detected part 31 engaged with the mooring line 11. The influence of the extension of the mooring line 11 during mooring can be minimized. When the balloon 10 is moored and when the mooring line 11 is wound up to store the balloon 10, the mooring line 11 extends by 1 to 2% due to the tension according to the wind pressure received by the balloon 10. When the total length of the mooring line 11 is 100 m, an error of 1 to 2 m occurs in the length of the mooring line 11 due to the extension of the mooring line 11 between when the mooring line 11 is unwound and when it is wound. On the other hand, since the detected part 31 is engaged at a position about 6 m away from the balloon 10, the error caused by the extension of the mooring line 11 is as small as about 6 to 12 cm. small.

  In the mooring balloon 1, the detected part 31 includes the magnet 311. Therefore, each of the first detecting part 32 and the second detecting part 33 does not use an optical sensor such as an optical sensor. Since it can be detected, it is less likely to be affected by weather such as rainfall.

  Further, in the mooring balloon 1, each of the plurality of magnets 311 is a plurality of cylindrical members in which through holes through which the mooring line 11 passes are formed, so that the possibility of lowering the flexibility of the mooring line 11 is low. There is a low possibility that each of the plurality of magnets 311 will not easily pass through the four-sided roller 14.

  FIG. 7 is a diagram illustrating a state in which the detected portion 31 passes through one roller 701 of the four-sided roller 14.

  The adhesive strength at which the fixing member 315 adheres the plurality of magnets 311 is a strength that allows each of the plurality of magnets 311 to move according to the force received from the roller 701 when passing through the roller 701. When the main mooring line 110 bends along the outer periphery of the roller 701, each of the plurality of magnets 311 moves in accordance with the force received from the roller 701, so that the side faces the surface facing the roller 701. Separate. When the mooring line 11 is curved along the outer periphery of the roller 701, each of the plurality of magnets 311 is separated from each other, so that the detected portion 31 can pass through the roller 701.

  In the mooring balloon 1, the detected portion 31 further includes a movement range limiting member 312 that limits the movement range of the plurality of cylindrical members, so that any one of the plurality of magnets 311 moves as another magnet 311. There is no possibility that the moving range limited by the range limiting member 312 is separated from the moving range.

  In the mooring balloon 1, the movement range limiting member 312 is a string-like member, and bends according to the curvature of the main mooring line 110. Therefore, by arranging the movement range limiting member 312, The risk of lowering flexibility is low. In addition, the movement range limiting member 312 is wound around the plurality of magnets 311 and the movement range limiting member 312 by a fixing member 315, which is an adhesive tape in one example, so that the balloon 3 is in close contact with the mount 131. Can be easily fixed to the position of

  Further, in the mooring balloon 1, in addition to the first detection unit 32, the length of the mooring line 11 between the balloon 10 and the winding device 20 is shorter than the storage length detected by the first detection unit 32. It further has the 2nd detection part 33 which outputs the overwinding signal which shows having come to take length. Since the mooring balloon 1 has the second detection unit 33, even if the first detection unit 32 cannot detect the detected unit 31, the second detection unit 33 detects the detected unit 31, thereby winding the detected balloon 31. It is possible to prevent the balloon 10 from being damaged when the device 20 winds the mooring cable 11 too much.

(Modification example of the mooring balloon according to the embodiment)
In the mooring balloon 1, the balloon 10 is stored using the detection unit 31 including the plurality of magnets 311 and the storage detection sensor 30 including the first detection unit 32 and the second detection unit 33 that detect the plurality of magnets 311. The winding device 20 is stopped. However, in the mooring balloon according to the embodiment, another type of storage detection sensor that detects that the balloon 10 is stored in the storage position may be employed. For example, the mooring balloon according to the embodiment may be a pressure sensor that is disposed on the surface of the landing table 13 and detects a pressure when the balloon 10 is stored on the landing table 13. The mooring balloon according to the embodiment includes a mooring line length sensor 25 that measures the unwinding length of the mooring line 11 wound by the winding device 20 and the winding length of the mooring line 11 wound by the winding device 20. You may employ | adopt as a storage detection sensor.

  Further, in the mooring balloon 1, the detected portion 31 has a magnet 311 that is a plurality of cylindrical members in which through holes through which the mooring lines 11 pass are formed, but through holes through which the mooring lines 11 pass are formed. The plurality of cylindrical members may not be magnets. For example, the plurality of cylindrical members formed with through holes through which the mooring line 11 passes may be colored with a color different from the color of the mooring line 11.
