Description

Infrared target simulator with continuously variable size

The present invention relates to an infrared target simulation apparatus, and more particularly, to an infrared target simulation apparatus having a continuously variable size that can continuously vary the size of the target.

An infrared target simulation apparatus mounted on a moving object for training and serving as a virtual target serves to emit infrared rays from the target simulation apparatus and recognize the emitted infrared rays as a target.

FIG. 7 shows an infrared target simulation apparatus 100 according to the prior art, and the infrared target simulation apparatus 100 according to the prior art uses infrared rays emitted by the heating of the wire coil.

For example, when power is applied to the wire coil in a state in which the wire coil wound in the housing 210 is stored, infrared rays are emitted while the wire coil is heated.

The infrared rays thus emitted pass through the light transmission window 221 formed in different sizes on the rotating plate 220 rotatably installed in the housing 210, thereby serving as a target simulation.

However, in the prior art infrared target simulation apparatus having the above configuration, since infrared rays are radiated by heat generated by applying power to the wire coil, it takes a long time to reach the temperature at which the infrared rays are radiated, and infrared rays are generated by heat generation. There is a risk of fire due to heat generation since it must be radiated.

In addition, since the size of the light transmission window 221 formed on the rotating plate 220 is fixed, it can only be used in a discontinuously set size, there is a problem that can not simulate the target to any size.

In addition, there is a problem that cannot be simulated when two targets are adjacent to each other. In other words, in order to determine if two targets are adjacent to each other and affect target recognition, infrared rays should be emitted adjacent to each other. At this time, in the infrared target simulation apparatus according to the prior art, in the arrangement of the two infrared target simulation apparatus, the emitted infrared rays cannot be located adjacent to each other. Since the infrared target simulation apparatus was bulky and there was no space for the infrared radiation emitted from the adjacent infrared target simulation apparatus to transmit, the target simulation apparatus could not be operated in a state adjacent to each other.

The present invention has been invented to solve the above problems, and an object of the present invention is to provide an infrared target simulation apparatus having a continuously variable size that can continuously adjust the size of the emitted infrared radiation using the principle of the aperture.

It is another object of the present invention to provide an infrared target simulation apparatus having a continuously variable size that allows infrared radiation to be rapidly radiated using a halogen lamp without using the heat of the coil and can easily adjust the size of the target to a desired size. It is.

It is still another object of the present invention to provide an infrared target simulation apparatus having a continuously variable size which allows the infrared simulation targets to be disposed adjacent to each other.

It is preferable that the said infrared lamp is a halogen lamp.

The lamp housing may further include an aspherical lens through which the infrared radiation emitted from the infrared lamp passes.

The aperture driving unit may adjust the opening of the aperture by transmitting a driving motor, an aperture to adjust the opening degree by operation of the driving motor, and determining a light transmitting area of the infrared ray, and transmitting the rotational force of the driving motor to the aperture. It characterized in that it comprises a power transmission unit.

The power transmission unit may include a drive gear that is integrally rotated with the drive motor, and a sector gear that is connected to the aperture and rotates by the drive gear to drive the aperture so that the opening of the aperture is adjusted. It is characterized by.

The sector gear may further include a balance gear meshed with the driving gear at intervals.

The sector gear is provided with a sensor operation pin for operating the sensing means, characterized in that it further comprises a plurality of sensing means for sensing the rotational position of the sector gear to detect the open state of the aperture.

Here, the detecting means is preferably a home sensor for detecting the initial opening state of the aperture, an upper limit switch for sensing the maximum opening state of the aperture, and a lower limit switch for sensing the minimum opening state of the aperture. .

Frame 110 allows other components to be installed. The lamp unit 120 to be described later is installed in the frame 110, and is also used to fix the infrared target simulation apparatus 100 having a continuously variable size according to the present invention to a moving object.

One side of the frame 110 is formed with a vertical portion 112 extending substantially perpendicular to the frame 110, so that the aperture driver 130 to be described later is installed.

In addition, the vertical part 112 is provided with a front cover 113 surrounding the outside of the aperture driver 130 in a state in which the aperture driver 130 is installed. At this time, one side of the front cover 113 is formed with a light transmitting groove 113a concave inwardly, when the plurality of infrared target simulation apparatus 100 is arranged (see FIGS. 5 and 6), the rear Infrared target simulation device 100 located in to form a space that can pass through the infrared radiation emitted.

The lamp unit 120 includes an infrared lamp 122 that emits infrared rays, and serves to emit infrared rays from the infrared lamp 122. To this end, the lamp unit 120 controls the direction in which the lamp housing 121, the infrared lamp 122 accommodated in the lamp housing 121, the infrared radiation emitted from the infrared lamp 122 is emitted. Aspherical lens 123 is included.

Lamp housing 121 is provided on one side of the frame 110, so that the other components of the lamp unit 120 is installed.

The infrared lamp 122 is installed in a shape accommodated inside the lamp housing 121 and emits infrared rays when power is applied. Unlike in the prior art for the infrared radiation, by applying power to the wire coil to emit infrared radiation by the heat of resistance, the infrared radiation is radiated by the infrared lamp 122 when the power is applied, so that The risk of fire due to disappears, there is an advantage that the infrared radiation is emitted immediately after the power is applied.

On the other hand, the infrared lamp 122 is preferably a halogen lamp. Infrared radiation is emitted using the halogen lamp, in particular, a 2200 ° C halogen lamp, thereby reducing the risk of fire due to heat generation of the wire coil and overcoming the maximum temperature limit. The halogen lamp has characteristics as shown in FIG. 4, and infrared rays are radiated within a short time after power is applied.

Aspherical lens 123 is provided on one side of the lamp housing 121, so that the infrared radiation emitted from the infrared lamp 122 is irradiated in parallel. Since the infrared lamp 122 is a point light source, the infrared radiation emitted from the infrared lamp 122 propagates in all directions. In this case, the aspherical lens 123 is used by using the aspherical lens 123 installed in the lamp housing 121. The infrared rays passing through may be radiated in parallel.

In addition, a rear cover 114 may be further provided on a rear surface of the lamp housing 121 to prevent infrared rays from being reflected backwards. The rear cover 114 is installed at the rear end of the frame 110 or is installed at the rear of the lamp housing 121, the rear cover 114 is located on the rear of the lamp housing 121, the rear cover 114 is a lamp The infrared rays emitted from the housing 121 are reflected to prevent the infrared rays from being reflected back.

The aperture driver 130 continuously varies the radiation size, that is, the radiation area, emitted from the infrared lamp 122. The aperture driving unit 130 is connected to the driving motor 131, the power transmission unit 132 for transmitting the rotational force of the driving motor 131, and the power transmission unit 132 so that the infrared rays are finally radiated. It includes an aperture 134 for adjusting the area. The aperture driver 130 may be installed at the vertical part 112 of the frame 110, and the front cover 113 may surround the outside of the aperture driver 130.

The drive motor 131 rotates when power is applied. Here, the drive motor 131 is easy to control, it is preferable that the step motor can be rotated exactly by a desired angle.

When the iris 134 transmits power from the driving motor 131, the opening degree of the iris 134 is adjusted to determine a light transmission area through which infrared light passes through the iris 134. The diaphragm 134 arranges a plurality of diaphragm blades (not shown) arranged in an annular shape, and rotates one side of the plurality of diaphragm blades in a forward or reverse direction simultaneously by a mechanical mechanism to adjust the light emitting area. The detailed configuration of the aperture is disclosed in, for example, Korean Patent Laid-Open Publication No. 10-2008-0076820 (aperture driving device of an interchangeable-lens digital camera), and a detailed description thereof will be omitted. The aperture 134 is installed in the through hole formed in the vertical portion 112 and the front cover 113 of the frame 110.

The power transmission unit 132 transmits the rotational force of the drive motor 131 to the aperture 134. As a specific example, the power transmission unit 132 and the drive gear 132a fixed to the drive motor 131, the drive gear And a sector gear 132b meshed with 132a and connected to the aperture 134.

The drive gear 132a has a pinion shape and is fixed to the drive motor 131 to rotate integrally with the drive motor 131.

The sector gear 132b is engaged with the drive gear 132a and transmits the rotational force of the drive motor 131 input from the drive gear 132a to the aperture 134. The sector gear 132b is connected to the diaphragm 134 and increases the light emitting area by opening the diaphragm 134 according to the rotation direction of the sector gear 132b, or tightens the diaphragm 134 to reduce the light emitting area. Reduce

On the other hand, the sector gear 132b is engaged with the balance gear 133 having the form of a pinion gear at a position spaced apart from the drive gear 132a, so that the sector gear 132b when the sector gear 132b is rotated. To rotate in a stable state.

A plurality of sensing means detects the opening of the aperture 134 by grasping the position of the sector gear 132b.

As a specific configuration, the front cover 113, the home sensor for detecting the initial position of the sector gear 132b, the upper limit switch 143 and the lower limit for detecting the upper and lower limits of the sector gear 132b. A limit switch 144 is provided and a sensor operation pin 141 is installed on the sector gear 132b to operate the home sensor 142, the upper limit limit switch 143, and the lower limit limit switch 144.

The home sensor 142, the upper limit limit switch 143, and the lower limit limit switch 144 detect the position of the sector gear 132b to indirectly detect the opening state of the aperture 134. That is, the home sensor 142 detects the initial opening of the aperture 134 by sensing the initial position of the sector gear 132b, and the upper limit switch 143 and the lower limit switch 144 By detecting the upper limit and the lower limit of the rotation of the sector gear 132b, respectively, the maximum opening and the minimum opening of the aperture 134 are sensed. When the sensor operation pin 141 is located at the home sensor 142, the aperture 134 is opened to an initial setting value, and the sensor operation pin 141 is positioned at the upper limit limit switch 143 to the maximum. In the open state, the sensor operation pin 141 is located in the lower limit switch 144 means the minimum open state. In addition, the sensor operation pin 141 is located between the upper limit switch 143 and the lower limit switch 144. The rotation angle of the sector gear 132b may be limited by the upper limit switch 143 and the lower limit switch 144.

The operation of the infrared target simulation apparatus having a continuously variable size according to the present invention having the above configuration will be described.

The infrared target simulation apparatus 100 having a continuously variable size according to the present invention may be mounted on a moving object and moved together with the moving object, thereby serving as a virtual target.

When power is applied to the infrared lamp 122 in the lamp unit 120 of the infrared target simulation apparatus 100, infrared rays begin to radiate from the infrared lamp 122. The infrared rays emitted from the infrared lamp 122 are emitted to the outside through the aspherical lens 123 formed on one side of the lamp housing 121.

In addition, by using a halogen lamp, the infrared lamp 122 can rapidly emit infrared rays, as compared to allowing the wire coils to be heated to radiate infrared rays by applying power to the wire coils. In addition, since the infrared rays pass through the aspherical lens 123, the infrared rays are minimized from being dispersed.

As the light emitting area is adjusted while passing the infrared rays emitted from the lamp unit 120 through the aperture 134 of the aperture driver 130, the size of the target to be simulated can be made. That is, when the drive motor 131 is operated, the drive gear 132a rotates the sector gear 132b, and by adjusting the opening degree of the aperture 134 by the rotation of the sector gear 132b, You can create the size of the target you want to simulate.

In this case, since the opening degree of the aperture 134 is not a discontinuous value, but can be selected from a continuous value between the maximum opening and the minimum opening of the aperture 134, the infrared target simulation of the prior art shown in FIG. As in the apparatus 200, the size of the target could not be simulated only by the size set in advance on the rotating plate 220, but in the infrared target simulation apparatus 100 having the continuously variable size according to the present invention, the size of the target was continuously. Can be simulated.

Finally, the infrared rays emitted to the outside through the aperture 134 in which the light emitting area is adjusted may be recognized as a target.

On the other hand, as shown in Figure 5 and Figure 6, in order to simulate the state in which the targets are adjacent to each other, the infrared rays are arranged back and forth, so that the infrared radiation to the plurality of infrared target simulation apparatus 100, 100 'adjacent to each other, The aperture 134 of the infrared target simulation apparatus 100 located at the rear side is disposed to be viewed from the front side.

In this case, since the light emitting groove 113a is formed in the front cover 113, when the plurality of infrared target simulation apparatuses 100 and 100 ′ are disposed, the front cover 113 may be disposed to emit infrared rays more adjacently. . In the conventional infrared target simulation apparatus shown in FIG. 7, since the infrared rays emitted from the infrared target simulation apparatus 100 located at the rear side are hidden by the infrared target simulation apparatus located at the front side, the plurality of infrared targets are radiated to be adjacently emitted. There was a limit to the placement of the simulator. However, in the infrared target simulation apparatus having a continuously variable size according to the present invention, the projection groove 113a is formed in the front cover 113, so that the plurality of infrared target simulation apparatuses 100, 100 'are disposed back and forth. (See FIG. 5), the diaphragm 134 of the infrared target simulation apparatus 100 ′ positioned rearward by the floodlight 113a formed in the infrared target simulation apparatus 100 located at the front side is disposed to be seen in front. (See FIG. 6).

Therefore, it is possible to simulate the case where the targets are located adjacent to each other.
