DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lift gauge used for a sky sports body, and more particularly to a lift gauge used for a sky sports body provided with a collision prevention device.

[0002]

2. Description of the Related Art Conventionally, in order to prevent a plurality of sky sports aircraft flying in a space from mutually colliding with each other, a pilot of a sky sports aircraft has conventionally avoided an aircraft approaching its own aircraft while paying attention to other aircraft. I had no choice but to take action. When piloting an aircraft used in sky sports such as a hang glider or a paraglider, the pilot always keeps an eye on other aircraft during the flight and tries to fly safely. Discovery of the approaching aircraft is late and very dangerous. In particular, in the direction directly above, the canopy of the own aircraft hinders the field of view, and the presence of other aircraft is often not noticed. By the way, since the pilot operating the upper body can easily check the lower body, the pilot of the lower body can be urged to evade by calling the pilot of the lower body. be able to. However, the lower body cannot always respond to this call. Further, even when the airframe is located above the other aircraft, it is not rare that the discovery of the other aircraft located below is delayed during the centering and other operations. As a result, air collisions occur frequently, and pilots often lose their lives.

SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator for use in a skysports body which solves the above-mentioned problems.

[0004]

Means for Solving the Problems Claim 1: A lift gauge main body 1 which allows a pilot to recognize the flight state of a gradual rise, a steep rise, and a descent of a skysports body by sound.
In addition, a skysporting device provided with an anti-collision device 4 that warns the pilot of the presence of another aircraft that is close to the aircraft's guard airspace d in all directions including above and behind the aircraft by an alarm sound. The lift gauge used for the aircraft was configured.

[0005] Claim 2: In the lift gauge used in the sky sports body described in claim 1, the lift gauge main body 1 and the collision prevention device 4 are connected to the flight condition alarm 3 via the OR circuit 2. The lift gauge used for the Sky Sports body to be connected was constructed. Further, in the lift gauge used for the sky sports body described in claim 2, the collision prevention device 4 includes a weak radio wave transmitting circuit 41, a radio wave for receiving a radio wave of the same frequency as the weak radio wave transmitting circuit 41. A receiving circuit 44, an alarm control circuit 45 for generating an alarm when a radio wave received by the radio wave receiving circuit 44 via the antenna 42 reaches a certain electric field strength threshold, and a transmission / reception switching circuit for randomly switching between radio wave reception and radio wave transmission The lift gauge used for the sky sports body composed of 43 was constructed.

Further, in the lifting and lowering device used in the sky sports body described in claim 3, the transmission / reception switching circuit 43 is set to perform transmission intermittently, and the weak radio wave transmission circuit 41 The elevator was used for an intermittently operated skysport aircraft.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention is to operate a sky sports aircraft used in sky sports such as a hang glider or a paraglider to warn a pilot of another aircraft abnormally approaching during flight by an alarm sound, An anti-collision device for preventing aerial collision beforehand is provided in a lift gauge normally provided in these sky sports aircraft.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An elevator mounted on a body used in sky sports is called a variometer in the technical field to which the body belongs. The elevating gauge is a barometer, a barometric altitude converter that converts a barometric pressure signal into an altitude signal, a barometric pressure increase rate detector, and a flight status indicator that sounds the flight status based on the detection signal of the barometric pressure increase rate detector. And The lift gauge is mounted on a hang glider or a paraglider, and measures a body altitude proportional to the barometric pressure by a barometric altitude converter while detecting a barometric pressure with a barometer. Here, when the airframe is rising, the lift gauge generates an intermittent sound via the atmospheric pressure increase rate detector and the flight status alarm.
The intermittent sound increases the frequency of the sound itself in proportion to the altitude of the airframe, and increases the repetition frequency of the intermittent sound in proportion to the acceleration of the airframe. Therefore, when the vehicle suddenly rises while increasing its speed, a sound is generated in which the number of sounds per unit time is increased while the pitch is increased. The occurrence of this intermittent sound allows the pilot to recognize that the aircraft is rapidly rising. When the aircraft is climbing without increasing speed, the elevometer will increase the pitch slightly without increasing the number of sounds per unit time via the barometric pressure increase rate detector and the flight status indicator Generates intermittent tones. Thereby, the pilot can recognize that the aircraft is gradually rising. Conversely, when the aircraft is descending, the elevating gauge emits a constant frequency continuous sound as an alarm sound via the barometric pressure increase rate detector and the flight condition alarm. The descent of the airframe in a hang glider or paraglider means that it is dangerous except in special cases, so that an audible alarm is generated.

According to the present invention, the above-mentioned elevator is provided with a collision preventing device for preventing a collision between the aircrafts for sky sports. An embodiment of the present invention will be specifically described with reference to FIG. In FIG. 1A, reference numeral 1 denotes a main body of the elevating gauge. Reference numeral 2 denotes an OR circuit, which is a transmission path for transmitting a signal of the atmospheric pressure increase rate detector generated by the main body 1 to the flight status indicator 3. Reference numeral 4 denotes the entire collision prevention device. 41
Is a weak radio wave transmission circuit. 44 is a weak radio wave transmission circuit 4
1 is a radio wave receiving circuit for receiving radio waves of the same frequency as 1.
An alarm control circuit 45 generates an alarm when the radio wave received by the radio wave receiving circuit 44 reaches a certain threshold value of the electric field strength. Reference numeral 43 denotes a transmission / reception switching circuit that randomly switches between radio wave reception and radio wave transmission. Reference numeral 42 denotes an antenna.
The random transmission / reception switching timing of the transmission / reception switching circuit 43 is as shown in FIG. The transmission / reception switching circuit 43 sets the transmission to be performed intermittently and operates the weak radio wave transmission circuit 41 intermittently, so that the power consumption of the collision prevention device can be reduced.

Referring to FIG. 2, the operation of the lift meter of the present invention in which the collision prevention device 4 is provided in the lift meter main body 1 will be described. In order to exhibit the collision prevention effect, the collision prevention device 4
On all skysport aircraft in flight. When a skysports aircraft equipped with the elevating gauge of the present invention is flying in a certain caution airspace d, the reception electric field strength of the weak radio wave transmitted by the weak radio wave transmission circuit 41 of another aircraft is equal to that of the own aircraft. The receiving circuit 44 cannot reach a certain threshold. Accordingly, the alarm control circuit 45 of the lift gauge does not generate an alarm control signal, and does not perform control to generate an alarm sound to the flight condition alarm 3. Conversely, if the sky sports aircraft equipped with the lift gauges abnormally approach to each other within the certain caution airspace d and cause a collision, the reception electric field strengths of both the lift meters are constant in the own-device radio wave reception circuit 44. Exceeds the threshold of the alarm control circuit 4
Reference numeral 5 generates an alarm control signal and controls the flight status alarm 3 to generate an alarm sound. As a result, the pilots of both aircraft can acoustically recognize that another aircraft is present in the certain cautionary airspace d.

[0011]

As described above, the elevator body 1 itself is an instrument that allows the pilot to appropriately recognize the flight state of the gradual ascent, rapid ascent, and descent of the skysports body equipped with the same by sound. However, by adding the anti-collision device 4 of the present invention to the body of the elevating gauge, the pilot is able to control the proximity of the other aircraft in the guarding airspace d of the aircraft in all directions including above and behind the aircraft. The presence is warned by the warning sound generated by the collision prevention device 4, and the collision can be prevented before it occurs. Therefore,
The ascent / descent meter according to the present invention, as an ascent / descent meter mounted on an airframe used in sky sports such as a hang glider or a paraglider, ensures the safety of a pilot more securely.

The radio wave transmitted from the collision prevention device 4 may be extremely weak, and it is not necessary to submit a license application using the radio wave. In addition, it is sufficient to perform transmission very weakly, intermittently, and randomly, and power consumption is extremely small. Therefore, a dry battery, a solar battery, or other small-sized small power supply can be used as drive power. Therefore, the anti-collision device 4 is attached to the main body 1 of the skysports aircraft, which is originally required to be small and light.
Does not reduce the weight and space factor of the entire elevometer, and the mode of use is preferable.
