  DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. The embodiments described below do not unduly limit the contents of the present invention described in the claims. Also, not all of the configurations described below are essential constituent requirements of the present invention.

1. Hot Air Balloon FIG. 1 is an external view of a hot air balloon. As shown in FIG. 1, the hot air balloon 1 is composed of a ball skin 2, a burner 3, a basket 4, and the like.

  The ball skin 2 is provided above the burner 3 and stores the air heated by the burner 3, so that the lower end is opened.

  The burner 3 (an example of a heat source) is provided below the bulb skin 2 and injects air heated by burning fuel such as propane into the bulb skin 2. Since the heated air is lighter than the cold air, buoyancy is generated by replacing the air inside the bulb skin 2 with lighter air, and the hot air balloon 1 rises.

  A person is in the basket 4. The basket 4 is made of a member such as rattan that absorbs an impact when landing, and is connected to the ball skin 2 by a wire. Inside the basket 4 are provided devices (not shown) such as an altimeter, an elevator, a fuel fuel gauge, a clock, a communication device, a ball skin thermometer, a GPS, a radio, and a lamp.

  In addition, the passenger can select either a manual flight mode in which the balloon 1 flies while manually operating or stopping the burner 3 and an automatic flight mode in which the balloon 1 automatically flies at a constant altitude (changed halfway). In order to realize this automatic flight mode, a control device 5 is provided inside the basket 4.

2. Control device 2-1. First Embodiment FIG. 2 is a diagram for describing a configuration example of a control device of a first embodiment. The control device 5 according to the first embodiment includes a switch device 100, a heat source control device 110, a power source 120, and a switch 130.

  The switch device 100 includes two terminals, and the terminals are in a conductive state or a non-conductive state according to the ambient atmospheric pressure. Specifically, when the ambient atmospheric pressure is higher than a predetermined atmospheric pressure value (threshold), the terminals of the switch device 100 are electrically connected, and when the ambient atmospheric pressure is lower than the predetermined atmospheric pressure value (threshold), the switch device 100 is connected. The terminals are not conductive. This threshold value may be a preset fixed value or a variable value that can be changed during the flight of the hot air balloon 1.

  The heat source control device 110 is connected to the power source 120 via the switch device 100 and the switch 130. The switch 130 is opened and closed by a flight mode selection signal. The switch 130 is opened when the manual flight mode is selected, and the switch 130 is closed when the automatic flight mode is selected. Therefore, when the manual flight mode is selected, power is not supplied from the power source 120 to the heat source control device 110, and the heat source control device 110 controls the operation of the burner 3 only when the automatic flight mode is selected. Specifically, when the automatic flight mode is selected, if the terminals of the switch device 100 are in a conductive state, power is supplied from the power source 120 to the heat source control device 110, and the heat source control device 110 operates the burner 3. Thereby, the burner 3 operates, the air heated by combustion is ejected to the ball skin 2, and the hot air balloon 1 rises gradually.

  On the other hand, when the automatic flight mode is selected, if the terminals of the switch device 100 are in a non-conductive state, power is not supplied from the power source 120 to the heat source control device 110, and the heat source control device 110 does not operate the burner 3. Thereby, the air inside the bulb skin 2 is naturally cooled, and the hot air balloon 1 gradually descends.

  In this embodiment, before the hot air balloon 1 takes off, the terminals of the switch device 100 are in a conductive state. When the automatic flight mode is selected, the burner 3 automatically operates and the hot air balloon 1 rises. . As the hot air balloon 1 rises, the atmospheric pressure around the hot air balloon 1 becomes lower, and when it falls below the set atmospheric pressure value (threshold value), the terminals of the switch device 100 become non-conductive. Then, the operation of the burner 3 is stopped and the hot air balloon 1 is lowered. When the hot air balloon 1 is lowered, the atmospheric pressure around the hot air balloon 1 is increased, and when the set atmospheric pressure value (threshold value) is exceeded, the terminals of the switch device 100 are brought into a conductive state again. Thereby, the burner 3 operates and the hot air balloon 1 rises again. When the automatic flight mode is selected, the hot air balloon 1 flies so that the surrounding atmospheric pressure matches the set atmospheric pressure value (threshold value) by repeating such an operation.

  In general, it is known that the relationship between the atmospheric pressure p and the altitude h satisfies the relationship of the following formula (1).

In the formula (1), t is the average temperature of the gas phase and p ₀ is the sea level pressure.

Therefore, the equation (1), setting pressure to the state in the non-conduction from the terminals conductive state of the switching device 100 value (threshold) in p _t, the calculation of an altitude hot air balloon 1 by the following formula (2) it can be kept constant altitude h _t being.

  Next, the switch device 100 capable of realizing such an operation will be described.

  FIG. 3 is a perspective view of the switch device 100. As shown in FIG. 3, the switch device 100 includes a first switch member 70, a second switch member 80, a stretchable member 30, a repellent material 90, and a container 50 that stores them.

  The first switch member 70 is configured by bending one end of a non-conductive (insulating) flat plate in a downward direction (on the second switch member 80 side), and the first electrode 10 is formed at the tip thereof. . The second switch member 80 is configured by bending one end of a non-conductive (insulating) flat plate in the upward direction (on the first switch member 70 side), and the second electrode 20 is formed at the tip thereof. ing. The first switch member 70 is fixed to the container 50, and the second switch member 80 is movable in the vertical direction (a direction toward and away from the first switch member 70).

  The repulsive material 90 is a member having elasticity such as a spring (push spring) or elastic rubber, for example, and both ends thereof are bonded and fixed to the lower surface of the second switch member 80 and the bottom of the container 50, respectively. Due to the elastic force of the repelling material 90, a force in a direction approaching the first switch member 70 is applied to the second switch member 80.

  A wiring 60 and a wiring 62 are connected to the first electrode 10 and the second electrode 20, respectively. The wiring 60 and the wiring 62 are drawn out of the container 50 and can be connected to external electronic components via terminals (not shown) provided at the tip.

  The elastic member 30 is provided between the first switch member 70 and the second switch member 80, and the second switch member 80 moves in the vertical direction (first switch member in conjunction with contraction / expansion of the elastic member 30. In a direction toward and away from 70).

  The container 50 is provided with a gas introduction hole 52 on a side surface, and gas enters and exits the container 50 through the gas introduction hole 52. Thereby, the internal atmospheric pressure of the container 50 varies. Although there may be one gas introduction hole 52, it is desirable to have a plurality of gas introduction holes.

  4, 5 and 6 are diagrams for explaining the operation of the switch device 100, and is a view of the switch device 100 as viewed from the front.

  In the vicinity of the ground, as shown in FIG. 4, the internal air pressure of the container 50 and the internal air pressure of the stretchable member 30 are equal, and the stretchable member 30 is on either the lower surface of the first switch member 70 or the upper surface of the second switch member 80. There is no contact. In this state, since the first electrode 10 and the second electrode 20 are in contact with each other, the first electrode 10 and the second electrode 20 are electrically connected.

  When the internal air pressure of the container 50 decreases from the state of FIG. 4, the elastic member 30 expands so that the internal air pressure of the container 50 and the internal air pressure of the elastic member 30 are balanced. When the internal air pressure of the container 50 matches a predetermined air pressure value (threshold value), the stretchable member 30 is placed on either the lower surface of the first switch member 70 or the upper surface of the second switch member 80 as shown in FIG. It comes into contact.

  When the internal pressure of the container 50 further decreases from the state of FIG. 5, the second switch member 80 moves downward (in the direction away from the first switch member 70) due to the expansion of the elastic member 30, as shown in FIG. 6. In addition, a gap is generated between the first electrode 10 and the second electrode 20. Therefore, the 1st electrode 10 and the 2nd electrode 20 will be in a non-conducting state.

  Further, when the internal air pressure of the container 50 rises from the state of FIG. 6, the elastic member 30 contracts so that the internal air pressure of the container 50 and the internal air pressure of the elastic member 30 are balanced. When the elastic member 30 contracts, the second switch member 80 moves upward (in the direction approaching the first switch member 70) by the elastic force of the repelling material 90, and the internal pressure of the container 50 is a predetermined pressure value (threshold value). If they coincide with each other, the first electrode 10 and the second electrode 20 come into contact with each other as shown in FIG. Therefore, the first electrode 10 and the second electrode 20 are conducted.

  As described above, the switch device 100 is in a conductive or non-conductive state according to a change in the internal pressure of the container 50.

FIG. 7 is a diagram for explaining an example of the flight trajectory of the hot air balloon 1 when the automatic flight mode is selected. As shown in FIG. 7, when the hot air balloon 1 takes off at time t ₀ , the terminals of the switch device 100 are electrically connected (ON). For this reason, when the automatic flight mode is selected, the burner 3 automatically operates and the hot air balloon 1 gradually rises.

When hot air balloon 1 at time t ₁ reaches the altitude h _o, since the ambient air pressure is below a threshold, between the terminals of the switch device 100 becomes non-conductive (OFF). Therefore, the operation of the burner 3 is stopped, and the hot air balloon 1 is gradually lowered by the inertial force and then gradually lowered.

When hot air balloon 1 is moved down to the height h _o at time t _2, the order around the pressure exceeds a threshold, between the terminals of the switch device 100 is turned conductive (ON) again. Therefore, the burner 3 operates, and the hot air balloon 1 gradually rises after being slightly lowered by the inertial force.

When hot air balloon 1 at time t ₃ reaches the height h _o, since the ambient air pressure is below a threshold, between the terminals of the switch device 100 becomes non-conductive again (off). Therefore, the operation of the burner 3 is stopped, and the hot air balloon 1 is gradually lowered by the inertial force and then gradually lowered.

Since the switch device 100 repeats the same operation, the non-conductive at time _t 3 ~t ₄ (off), conducting at time _t 4 ~t ₅ (on), at time _t 5 ~t ₆ non-conductive (OFF) At time _t 6 ~t ₇ conductive (oN), the .... In accordance with this, the burner 3 repeatedly operates and stops, and the hot air balloon 1 can continue to fly while maintaining a constant altitude _ho .

  As described above, according to the control device of the first embodiment, it is possible to fly a balloon while maintaining a predetermined altitude by selecting an automatic flight mode from the beginning or midway. .

  Further, since the pressure value (threshold value) at which the switch device 100 is switched from the conductive state to the non-conductive state can be adjusted by adjusting the amount of gas sealed in the elastic member 30 of the switch device 100 in advance, the balloon The flight altitude of 1 can be set freely.

  Furthermore, if a plug capable of introducing and discharging gas is provided in the stretchable member 30 during the flight of the balloon 1, and the amount of the enclosed gas can be adjusted, the flight altitude of the balloon 1 can be changed flexibly and easily. can do. For example, when the balloon 1 rises and a passenger finds a wind blowing in a target direction at a certain altitude, the altitude is maintained by increasing or decreasing the amount of gas enclosed in the elastic member 30. It is also possible to fly the balloon 1.

2-2. Second Embodiment In the control device 5 of the first embodiment, when the automatic flight mode is selected, power is supplied from the power source 120 to the heat source control device 110 only when the switch device 100 is in a conductive state, so that the burner 3 operates. However, in the control device 5 of the second embodiment, when the automatic flight mode is selected, the heat source control device 110 is always supplied with electric power from the power source 120, and determines whether the switch device 100 is conductive or non-conductive to determine the burner 3 Control the operation of

  FIG. 8 is a diagram for explaining a configuration example of the control device 5 according to the second embodiment.

  Since the structure and operation of the switch device 100 are the same as those of the first embodiment (FIGS. 3 to 6), description thereof is omitted.

  The heat source control device 110 is connected to the power source 120 via the switch 130 and is connected to both terminals of the switch device 100. The switch 130 is opened and closed by a flight mode selection signal. The switch 130 is opened when the manual flight mode is selected, and the switch 130 is closed when the automatic flight mode is selected. Therefore, when the manual flight mode is selected, power is not supplied from the power source 120 to the heat source control device 110, and the heat source control device 110 controls the operation of the burner 3 only when the automatic flight mode is selected. In the present embodiment, the heat source control device 110 includes a switch state determination unit 100 and a heat source operation control unit 110.

  The switch state determination unit 100 determines whether the terminals of the switch device 100 are conductive or nonconductive. For example, the switch state determination unit 100 measures the current value flowing between the terminals of the switch device 100, and when the current value greater than or equal to a predetermined value (threshold value) is measured, the switch state determination unit 100 measures the current value less than the predetermined value (threshold value). In such a case, it may be determined that it is non-conductive.

  The heat source operation control unit 110 controls the operation of the burner 3 according to the determination result of the switch state determination unit 100. Specifically, the heat source operation control unit 110 operates the burner 3 if the terminals of the switch device 100 are in a conductive state. Thereby, the burner 3 operates, the air heated by combustion is ejected to the ball skin 2, and the hot air balloon 1 rises gradually.

  On the other hand, if the terminals of the switch device 100 are in a non-conductive state, the heat source operation control unit 110 does not operate the burner 3. Thereby, the air inside the bulb skin 2 is naturally cooled, and the hot air balloon 1 gradually descends.

  FIG. 9 is a diagram illustrating an example of a flowchart of processing by the heat source control device 110 in the present embodiment.

  As shown in FIG. 9, when the automatic flight mode is not selected (the manual flight mode is selected) (N in S10), the heat source control device 110 does not operate.

  On the other hand, when the automatic flight mode is selected (Y in S10), the heat source control device 110 determines whether or not the terminals of the switch device 100 are in a conductive state (S12).

  The heat source control device 110 operates the burner 3 if the terminals of the switch device 100 are conductive (Y in S14) (S16), and does not operate the burner 3 if it is non-conductive (N in S14) (N in S14). S18).

  And the heat source control apparatus 110 repeats the process of step S12-S18, while automatic flight mode is selected (Y of S10).

  According to the hot air balloon of 2nd Embodiment demonstrated above, there can exist an effect similar to the hot air balloon of 1st Embodiment.

2-3. Third Embodiment A configuration example of the control device of the third embodiment is the same as that of the second embodiment (FIG. 8), and thus illustration thereof is omitted. However, the functions of the switch device 100 and the heat source control device 110 are different.

  In this embodiment, when the ambient atmospheric pressure is higher than a predetermined atmospheric pressure value (threshold), the terminals of the switch device 100 are non-conductive, and when the ambient atmospheric pressure is lower than the predetermined atmospheric pressure value (threshold), the switch The terminals of the device 100 are electrically connected. This threshold value may be a preset fixed value or a variable value that can be changed during the flight of the hot air balloon 1.

  In the present embodiment, the heat source operation control unit 110 of the heat source control device 110 operates the burner 3 if the terminals of the switch device 100 are in a non-conductive state. Thereby, the burner 3 operates, the air heated by combustion is ejected to the ball skin 2, and the hot air balloon 1 rises gradually.

  On the other hand, if the terminals of the switch device 100 are in a conductive state, the heat source operation control unit 110 does not operate the burner 3. Thereby, the air inside the bulb skin 2 is naturally cooled, and the hot air balloon 1 gradually descends.

  In this embodiment, before the hot air balloon 1 takes off, the terminals of the switch device 100 are in a non-conductive state, and when the automatic flight mode is selected, the burner 3 automatically operates and the hot air balloon 1 To rise. As the hot air balloon 1 rises, the atmospheric pressure around the hot air balloon 1 becomes lower, and when it falls below the set atmospheric pressure value (threshold value), the terminals of the switch device 100 become conductive. Then, the operation of the burner 3 is stopped and the hot air balloon 1 is lowered. When the hot air balloon 1 is lowered, the atmospheric pressure around the hot air balloon 1 is increased, and when the set atmospheric pressure value (threshold value) is exceeded, the terminals of the switch device 100 are again brought into a non-conductive state. Thereby, the burner 3 operates and the hot air balloon 1 rises again. When the automatic flight mode is selected, the hot air balloon 1 flies so that the surrounding atmospheric pressure matches the set atmospheric pressure value (threshold value) by repeating such an operation.

Therefore, the equation (1) is calculated when the pressure value between the terminals of the switch device 100 is changed to a conduction state from a non-conductive state (threshold) is set to p _t, the hot air balloon 1 an altitude by the formula (2) it can be maintained in that fixed altitude h _t.

  Next, the switch device 100 capable of realizing such an operation will be described.

  FIG. 10 is a perspective view of the switch device 100. As shown in FIG. 10, the switch device 100 stores the first switch member 70, the second switch member 80, the stretchable member 30, the rebound material 90, and these as in the first embodiment (FIG. 3). A container 50 is included. However, the arrangement of the elastic member 30 and the rebound material 90 is different.

  The elastic member 30 is provided below the second switch member 80, and the second switch member 80 moves in the vertical direction (direction approaching the first switch member 70 in conjunction with expansion / contraction of the elastic member 30. And move away).

  Both ends of the repellent material 90 are bonded and fixed to the lower surface of the first switch member 70 and the upper surface of the second switch member 80, respectively. Due to the elastic force of the repelling material 90, a force in a direction away from the first switch member 70 is applied to the second switch member 80.

  Since the other structure of the switch apparatus 100 in this embodiment is the same as that of 1st Embodiment (FIG. 3), the description is abbreviate | omitted.

  11, 12 and 13 are diagrams for explaining the operation of the switch device 100 according to the present embodiment, and is a view of the switch device 100 as viewed from the front.

  In the vicinity of the ground, as shown in FIG. 11, the internal pressure of the container 50 is equal to the internal pressure of the elastic member 30, and the elastic member 30 does not contact the bottom of the container 50, and is not on the lower surface of the second switch member 80. In contact. In this state, since a gap is generated between the first electrode 10 and the second electrode 20, the first electrode 10 and the second electrode 20 are not conductive.

  When the internal air pressure of the container 50 decreases from the state of FIG. 11, the elastic member 30 expands so that the internal air pressure of the container 50 and the internal air pressure of the elastic member 30 are balanced. Then, when the internal atmospheric pressure of the container 50 matches a predetermined atmospheric pressure value (threshold value), the stretchable member 30 is in contact with both the bottom of the container 50 and the lower surface of the second switch member 80 as shown in FIG. become.

  When the internal pressure of the container 50 further decreases from the state of FIG. 12, the expansion of the elastic member 30 causes the second switch member 80 to move upward (in the direction approaching the first switch member 70), as shown in FIG. The first electrode 10 and the second electrode 20 are in contact with each other. Therefore, the 1st electrode 10 and the 2nd electrode 20 will be in a conduction state.

  When the internal pressure of the container 50 rises from the state of FIG. 13, the elastic member 30 contracts so that the internal pressure of the container 50 and the internal pressure of the elastic member 30 are balanced. When the internal pressure of the container 50 exceeds a predetermined pressure value (threshold value), the second switch member 80 moves downward (in the direction away from the first switch member 70) by the elastic force of the repellent material 90, and the first A gap is generated between the electrode 10 and the second electrode 20. Therefore, the 1st electrode 10 and the 2nd electrode 20 will be in a non-conducting state.

  As described above, the switch device 100 is in a conductive or non-conductive state according to a change in the internal pressure of the container 50.

  FIG. 14 is a diagram illustrating an example of a flowchart of processing performed by the heat source control device 110 according to the present embodiment.

  As shown in FIG. 14, when the automatic flight mode is not selected (the manual flight mode is selected) (N in S110), the heat source control device 110 does not operate.

  On the other hand, when the automatic flight mode is selected (Y in S110), the heat source control device 110 determines whether or not the terminals of the switch device 100 are in a conductive state (S112).

  The heat source control device 110 does not operate the burner 3 if the terminals of the switch device 100 are in a conductive state (Y in S114) (S116), and operates the burner 3 if it is in a non-conductive state (N in S114) ( S118).

  And the heat source control apparatus 110 repeats the process of step S112-S118, while automatic flight mode is selected (Y of S110).

FIG. 15 is a diagram for explaining an example of the flight trajectory of the hot air balloon 1 when the automatic flight mode is selected. As shown in FIG. 15, when the hot air balloon 1 takes off at time t ₀ , the terminals of the switch device 100 are non-conductive (off). For this reason, when the automatic flight mode is selected, the burner 3 automatically operates and the hot air balloon 1 gradually rises.

When hot air balloon 1 at time t ₁ reaches the altitude h _o, since the ambient air pressure is below a threshold, between the terminals of the switch device 100 is turned conductive (ON). Therefore, the operation of the burner 3 is stopped, and the hot air balloon 1 is gradually lowered by the inertial force and then gradually lowered.

When hot air balloon 1 is moved down to the height h _o at time t _2, the order around the pressure exceeds a threshold, between the terminals of the switch device 100 becomes non-conductive again (off). Therefore, the burner 3 operates, and the hot air balloon 1 gradually rises after being slightly lowered by the inertial force.

When hot air balloon 1 at time t ₃ reaches the height h _o, since the ambient air pressure is below a threshold, between the terminals of the switch device 100 is turned conductive (ON) again. Therefore, the operation of the burner 3 is stopped, and the hot air balloon 1 is gradually lowered by the inertial force and then gradually lowered.

Since the switch device 100 repeats the same operation, conducting at time _t 3 ~t ₄ (ON), at time _t 4 ~t ₅ non-conductive (OFF), conducting at time _t 5 ~t ₆ (on), At time _t 6 ~t ₇ non-conductive (off), the .... In accordance with this, the burner 3 repeatedly operates and stops, and the hot air balloon 1 can continue to fly while maintaining a constant altitude _ho .

  According to the control apparatus of 3rd Embodiment demonstrated above, there can exist an effect similar to the hot air balloon of 1st Embodiment.

  In the first to third embodiments, the example applied to the manned flight of the balloon has been described. However, the automatic flight mode can always be applied to the unmanned flight. For example, the present invention can be applied to an application in which weather data of an altitude is acquired by flying an unpopular sphere while maintaining a predetermined altitude set in advance.
