Abstract

PURPOSE:To enable flexible and easy monitoring in a wide range of a golf course, etc., using a sky monitoring device by carrying a floating trajectory structure in which gas lighter than air is filled with a propeller and a small video camera so that monitoring and recording can be made through a ground monitor. CONSTITUTION:A balloon 1 in which helium gas is filled is carried with a propeller 3, a TV camera 5, a wind-direction & speed sensor 2 and a camera operation base 4, the operation base 4 and a ground monitor connected together via a transmission feed cord 6. In this way, the balloon 1 connected to the ground via the cord 6 has no trouble to be blown off, and moves in a wide range using the propeller 3 to take pictures through the TV camera 4 and send them to the ground monitor. It is thus possible to make flexible and easy monitoring in a wide range.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention targets a certain wide area, such as power transmission line equipment, a golf course, or a large parking lot, and easily and freely monitors or records the area from above. This relates to an upper air monitoring device for use in the air.

[Prior Art] It is extremely dangerous for people other than those involved to enter power transmission line equipment, etc., and even if there is an abnormality in the equipment, there is a great danger that it may occur. It is necessary to have a system in place that can constantly monitor the presence or absence of equipment and equipment abnormalities.

Similar things are desired at golf courses and large parking lots, such as early detection of abnormalities such as the flow of players on the course and the occurrence of sick people, confirmation of vacant positions in parking lots, and prevention of vehicle accidents. It is also desirable to install monitoring equipment for detection purposes.

Conventionally, for such monitoring, for example, as shown in FIG. It has been common practice to monitor using a device 11, a CRT 12, an operation panel 13, etc.

Furthermore, when the monitoring range becomes wider, such as with power transmission line equipment, helicopters are regularly flown in to monitor from above, and patrols by observers are also common for maintenance monitoring.

[Problems to be Solved by the Invention] The above-mentioned system in which the TV left camera is installed tends to have a blind spot because the TV left camera is fixed, and to compensate for this, a large number of TV left cameras must be installed, which is uneconomical. It is. Furthermore, even if you do this, you cannot avoid the restriction that the TV left camera is fixed, and even if you try to see the situation at a remote location, you will often be troubled by unclear images.

Furthermore, since monitoring by helicopter itself requires a huge amount of cost, there is a limit to the frequency of monitoring. Furthermore, in the case of patrols by lifeguards, in remote mountainous areas, they must walk from the road to the site of the steel tower, which requires a great deal of effort.

SUMMARY OF THE INVENTION In view of the above-mentioned circumstances, an object of the present invention is to provide a novel sky surveillance device that can be constructed at a relatively low cost and that can monitor a wide area freely and easily from the sky. be.

[Means for Solving the Problems] The present invention provides a floating flying object that is filled with a gas having a specific gravity lower than that of air and is capable of floating in the sky, and is equipped with a propulsion device and a small video camera, and a monitor installed on the ground. It is configured to enable monitoring or recording.

[Operation] Since the floating flying object is equipped with a propulsion device, it can move freely above the monitoring area, and can easily monitor the entire area with one device, without the risk of creating a blind spot.

[Example] The present invention will be described below with reference to Examples.

FIG. 1 is a sketch showing a specific example of the configuration of a monitoring device according to the present invention.

Reference numeral 1 denotes an elliptical balloon, which is filled with gas having a specific gravity lighter than air so that it can float at an altitude of, for example, 50 to 200 meters.

As such a gas, helium gas, which is used in airships, etc., is suitable.

Reference numeral 2 is a sensor capable of sensing wind direction and wind speed, and a structure may be added that serves as a vertical stabilizer to enable direction change.

3 is a propeller for propulsion, and the rotation speed of this propeller is increased or decreased by computer processing in proportion to the speed of the airflow in the air detected by sensor 2, so that it can not only move forward and backward, but also stay in a fixed position for a long time. Configure as possible.

Reference numeral 4 denotes a camera operation console, and a TV right camera is attached to the operation console 4, and images can be displayed on the ground by commanding the swing and zoom operations of the TV right camera from the ground via the transmission power supply cord 6. (not shown, but is substantially the same as the example shown in Figure 2), and can be monitored or recorded on video based on the images captured by the TV right camera on the ground. It becomes.

Since the monitoring device according to the present invention is connected to the ground by the cord 6 as described above, there is no risk of it being blown away.
This can be permanently installed in the required monitoring area. Alternatively, it can be transported and moved, for example, it can be floated over the road near the power transmission line support, and the power transmission line support can be directly monitored from the road without the need for a supervisor to walk there. Significant labor savings can be achieved.

In addition, even if it is permanently installed in a wide range of areas to be monitored, such as golf courses, amusement parks, port facilities, and large parking lots, there is no need to construct large supports such as steel towers, so it is extremely economical. Highly advantageous.

[Effects of the Invention] As described above, the monitoring device according to the present invention enables flexible monitoring from the sky with a simple and inexpensive configuration.
There is no risk of blind spots even with just one device,
Not only can it be permanently installed without requiring special structures such as steel towers, but it can also be used for mobile monitoring, making it extremely convenient and economical.
