Consists of.

Next, the operation of this embodiment will be explained.

Balloon 1 with sufficient buoyancy and holding equipment 2 for monitoring
are connected to each other by a rope 5a, and the arresting device 2 is lifted into the sky at a predetermined altitude. Further, the holding device 2 is coupled to the row 15b, and one end of the row 15b is fixed to the ground. Therefore, the holding device 2 is fixed in the sky by the ropes 5a and 5b.

The pin-holding device 2 is equipped with a thrust generating device 11 for making the entire position of the pin-holding device 2 fixed in the sky movable. -Finally, the thrust generator 11 receives control commands from the ground equipment 3 via the control unit 13 using a highly efficient small-sized internal combustion engine as power to control the thrust and direction. The position of the holding device 2 can be moved. For the internal combustion engine that is the power source of the thrust generating section 11.
The required amount of fuel is secured in the tank 111. The thrust generating unit 11 moves the entire stopping device 2 including the balloon 1 to a desired position by rotating a propeller disposed on the head in the control direction, and changes the imaging direction of the camera unit 15 to the desired direction. can be directed to. The direction of movement by the thrust generator 11 is based on the spatial coordinate axis detected by the gyroscope unit 12, and the thrust generator 11 rotates in the direction commanded by the ground device 3, and when it rotates to the commanded angle, the position is determined. to stop and maintain the commanded direction.

The pinholding device 2 includes a thrust generating unit 11 that controls the position of the pinholding device 2, a gyroscope unit 12 that detects the spatial coordinate axes, and a command signal from the ground device 3 to control and pin the pinhold device 2. A control unit 13 that sends information on the equipment 2 to the ground equipment 3 and a gimbal mechanism unit 14 equipped with a camera unit 15 that monitors monitoring are integrated, and the gyroscope unit 12 and control unit 13 are also integrated. It has a structure. Therefore, when the thrust generating section 11 turns in direction in response to a command from the ground, the entire shoot-down device 2 turns in direction, and the camera section 15 mounted on the gimbal mechanism section 14 also turns in direction. In order to prevent this, the angle signal from the gyroscope unit 12 is used to drive the gimbal mechanism section 14 by the control section 13 so that the correlation between the spatial coordinate axes detected by the gyroscope unit 12 is always maintained, and the camera section 15 I try to keep the direction constant. Furthermore, the left/right, up/down, and roll directions of the camera unit 15 are controlled by the ground equipment! By driving the gimbal mechanism section 14 with the control section 13 with respect to the reference axis of the gyroscope unit 12 in response to a command from the ground device 3, the direction commanded from the ground device 3 is always maintained regardless of the direction of the thrust generating section 11. It becomes possible to be suitable for

Depending on the purpose, the camera of the camera section 15 can be used to implement surveillance with a small and lightweight COD TV camera, or can be used in conjunction with a still camera to take photographs from above. Further, the link between the onboard equipment 2 and the ground equipment 3 can be easily realized by a wired system.

〔Effect of the invention〕

As explained above, according to the present invention, by using a balloon with sufficient buoyancy to hold the surveillance device in space, it can be used for ground surveillance of amusement parks, beaches, ski resorts, etc., and for photographing commemorative characters. This has the effect of realizing a ground monitoring device that can take aerial photographs of facilities, buildings, etc. at a low cost to set up.
