Description

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to an antenna mounting apparatus,

The present invention relates to an answering machine antenna mounting apparatus and an earpiece antenna mounting apparatus for an answering antenna of IFA (Identification Friend or Foe), and more particularly, And a peer identifier.

The PIA Identifier is mounted on a variety of military mission platforms including multi-function radar vehicles, combat vehicles, aircraft and ships. The PIA Identifier minimizes damage from false alleged firing by sending and receiving Ka-band RF signals of questions / responses to unidentified platforms to perform peer identification.

Forces operating various mission platforms should identify the target's peers in order to respond to targets of interest such as remote unknown platforms. To do this, the peer identifier sends a signal containing the query to the target. If the target does not respond to the question signal of the peer identifier or does not transmit the promised response signal, it can be considered not ally. The target sends a response signal to the interrogation signal. The peer identifier identifies the peer of the target by receiving and analyzing the response signal transmitted from the target. The peer identifier includes an interrogator that sends a query signal to the target and receives a response signal of the target, a responder that sends a response signal to the target and receives a query signal of the target, and a processor that processes the signals sent and received by the interrogator and responder .

The responder of the peer identifier has a bar-shaped omnidirectional antenna for smoothly transmitting and receiving a response signal and a question signal in all directions. Since the maximum distance and probability of the response vary depending on the angle of the antenna, it is difficult to identify the peer if the mission platform or target posture changes during operation.

Techniques as a background of the present invention are listed in the following patent documents.

2 through 5, a mounting apparatus 400 according to an embodiment of the present invention will be described in detail.

A mounting apparatus 400 according to an embodiment of the present invention is a mounting apparatus for mounting an antenna 50 on an object. The mounting apparatus 400 includes a base supporting one side of the antenna 50, facing the mounting unit, spaced apart from one surface of the object, And a robot arm connecting the driving unit 470 to the posture control surface of the base facing the driving unit 470 and the driving unit 470.

The object includes a responder 30 of the peer identifier and the antenna 50 may include an omni-directional antenna in the form of a round bar. At this time, the antenna 50 can be electrically connected to the transponder 30 through the mounting portion.

The base supports the lower side of the antenna 50 and faces the receiving portion 33 in one direction and is spaced apart from the upper surface of the transponder 30. [ The base is mounted on the lower side of the antenna 50 and spaced apart from the upper surface of the transponder 30 in one direction, for example, upward, and includes a first base 410 extending outward in one direction, And a second base 420 detachably mounted on a surface facing the lead portion 33, for example, a lower surface.

The first base 410 may be formed in a truncated cone shape having a smaller area from the lower part to the upper part. The first base 410 has an antenna 50 mounted on an upper surface thereof and a second base 420 mounted on a lower surface thereof.

The second base 420 may be formed in a disc shape having a central opening. The second base 420 may be mounted around the outer side of the center of the lower surface (also referred to as a 'bottom') of the first base 410. That is, the second base 420 may be mounted on the lower edge of the first base 410. On the other hand, the edge means the edge in the direction crossing the one direction.

The posture control surface may include opposing surfaces of the first base 410 and the second base 420. That is, the posture control surface may include the lower surface of the first base 410 and the upper surface of the second base 420. The first mounting groove 412 may be concave on the lower surface of the first base 410. The first installation groove 412 has an upper portion 412a in a cylindrical shape, a lower portion 412b in a hemispherical shape, and an inner diameter can be widened downward. The second mounting groove 422 may be recessed on the upper surface of the second base 420 facing the first base 410 so as to be connected to the first mounting groove 412. In the second installation groove 422, the upper portion 422a has a hemispherical shape, the lower portion 422b has a cylindrical shape, and the inner diameter increases toward the upper side.

The first installation groove 412 and the second installation groove 422 can define a space in which the robot arm can be installed on the attitude control surface. The robot arm can be inserted into the installation space defined by the first installation groove 412 and the second installation groove 422 at one end through the second base 420. [ The other end of the robot arm may pass through the upper surface of the driving unit 470 and may be inserted into the driving unit 470. The second base 420 may be spaced above the step 31 of the bottom surface.

The second base 420 has a central portion opened in one direction and a plurality of first installation grooves 412 and second installation grooves 422 are provided and the periphery of the opening 423 of the second base 420 Can be arranged. For example, three first installation grooves 412 may be provided corresponding to the number of robot arms, and similarly, three second installation grooves 422 may be provided corresponding to the number of robot arms. The first installation grooves 412 can be equiangularly spaced apart from each other with respect to the center axis in one direction on the attitude control surface and the second installation grooves 422 can also be formed on the posture control surface with respect to the central axis in one direction They can be spaced at an equal angle from each other. Of course, their spacing angles may vary.

The first binding members 411 can be formed by penetrating a plurality of positions of the edges of the first base 410 in one direction and the plurality of positions of the edges of the second base 420 can be penetrated in one direction, Spheres 421 may be formed. A binding member such as a pin (P) is inserted through these binding ports, and the pin (P) and binding ports can be screwed, for example.

On the other hand, the above-described base may be referred to as an antenna base.

The driving portion 470 can be accommodated in the accommodating portion 33 and can be fixed in the accommodating portion 33 by the step 31. [ That is, the driving unit 470 can be installed in the mounting portion. The driving unit 470 may include a hydraulic device, a servo motor, and a control board for controlling the operation thereof. Of course, the configuration of the driving unit 470 may be various. The driving unit 470 can operate the robot arm.

Meanwhile, the control board can communicate with the transponder 30 so as to adjust the angle of the antenna 50 to a desired angle. For example, the transponder 30 presents the desired antenna angle to the control board, and the control board operates the robot arm through the hydraulic device and the servo motor so that the angle of the antenna 50 can follow the proposed angle, The angles of the antennas 50 can be matched to the suggested angles.

The robot arm connects the driving part 470 to the posture control surface of the base facing the driving part 470. A plurality of robot arms are provided, and a plurality of points on the posture control surface and the driving unit 470 can be connected to each other. Here, the plurality of points may include a first point, a second point, and a third point that are radially spaced from the center of the attitude control surface. The above-mentioned installation grooves are formed at these points, and the installation space can be provided by the installation grooves.

That is, three robot arms are provided to adjust the height of three different points on the attitude control surface, adjust the attitude of the attitude control surface, and fine adjust the angle of the antenna 50 therefrom.

For example, one of the conditions that make up a plane is to define three points in space and form a plane passing through these three points. Therefore, in a method of adjusting the angle of one plane, there is a method of finely adjusting the angle of one plane to a desired angle by adjusting the position of three points in the space. In this way, the robot arm adjusts the height of the base by adjusting the height of a plurality of points on the attitude control surface, and finally, the angle of the supported antenna 50 can be finely adjusted to a desired angle.

At this time, the angles (?,? ') Of the antenna 50 may include a first angle? 1 component in the left and right direction and a second angle? 2 component in the front and rear direction. That is, it is possible to adjust the omnidirectional angle.

The robot arm may be provided with a cylinder 460 and a link 450 so as to control the distance between the upper surface of the transponder 30 and the corresponding point on the posture control surface connected to the robot arm. In addition, the robot arm may include a ball joint 430 to connect the cylinder 460 or the link 450 to the corresponding point.

The ball joint 430 can ensure the continuity of connection between the posture control surface and the robot arm, and the rigidity of the connecting portion can be ensured. The cylinder 460 may include a hydraulic cylinder and is mounted in one direction through the upper surface of the driving unit 470 and is capable of moving back and forth in one direction. The link 450 can transfer the movement of the cylinder 460 to the ball joint 430 and maintain their connection. The link 450 may include a plurality of link plates 451 and 452 spaced from each other in the left-right direction or the back-and-forth direction, and a link plate 453 connecting the link plates.

Hereinafter, an embodiment will be described with reference to one robot arm.

The robot arm is mounted in one direction to a driving unit 470 spaced in one direction from the base, one end of which is mounted in the installation space of the base so as to freely rotate on the posture control surface, And a connecting portion connecting the one end and the other end so as to be mutually rotatable with the end, the one end, and the other end.

Here, one end may include a ball joint 430. The ball joint 430 may include an upper ball member 431, a lower bar member 432 and a protrusion member 433 protruding from the outer circumferential surface of the bar member 432. The ball member 431 is accommodated in the installation space and the link 450 can be fastened to the projection member 433. [ The outer diameter of the bar member 432 may be smaller than the inner diameter of the lower portion 422b of the second installation groove 422. [ Thus, a space in which the ball joint 430 can rotate can be secured.

And the other end may include a cylinder 460. The cylinder 460 can be moved forward and backward by the hydraulic pressure, and the angle of the antenna 50 can be finely adjusted by the forward and backward movement. The upper end of the cylinder 460 may be bent in a direction crossing one direction.

The connection may include a link 450. The link 450 may exhibit two different movements by the support portion 440 described below. The cylinder 460 can be pulled or pushed in the same direction as the direction in which the cylinder 460 moves in the state of being separated from the support portion 440. In addition, The ball joint 430 can be pulled or pushed in a direction opposite to the direction in which the ball joint 430 is moved. Therefore, one robot arm can be driven in various motions, and therefore, the angle adjustment of the antenna 50 can be made more precise and finer.

The ball joint 430 extends in one direction and is mounted to the periphery (also referred to as an " edge ") of the base, the cylinder 460 extends in one direction and is spaced apart in a direction crossing one direction at the periphery of the base And the link 450 can extend in a direction crossing one direction.

The mounting device 400 may include a support 440 disposed between the base and the mount and providing a support surface to the robot arm. The support portion 440 may be in the shape of a disk having an opening 443 formed in the center portion thereof. The support portion 440 surrounds the outside of the cylinders 460 and can be supported on the upper surface of the step 31. [ A plurality of seating holes 442 and a plurality of third binding holes 441 may be formed through the supporting portion 440 in one direction. The seating holes 442 may be concave at the edge of the upper surface of the support portion 440 so as to accommodate the lower portion of the ball joint 430. The seating hole 442 may have an inner diameter of the upper portion 442a larger than an inner diameter of the lower portion 442b. The third binding member 441 may be fixed to the fixture 34 formed on one surface of the transponder 30 by a predetermined binding member (not shown).

The support portions 440 are spaced apart from each other in one direction with the base, extend in a direction intersecting one direction, and the center portion is open in one direction. On the other hand, in the structure of the robot arm described above, one end is mounted to the base in one direction and the other end passes through the opening 443 of the support portion 440 in one direction, and a connecting portion connecting one end and the other end And is disposed in a direction crossing one direction between the support portion and the base.

At this time, the support surface includes an upper surface that faces the connection portion of the support portion 440, and when the connection portion is in contact with the support surface, the movement of the other end portion can be transmitted to the one end portion with the support surface as a fulcrum P0 .

6 is a schematic view for explaining a method of operating an anvil antenna mounting apparatus of a peer discriminator according to an embodiment of the present invention.

L1 and L3 in the drawing correspond to the base, L2 and L3 correspond to the ball joint, L4 and L5 correspond to the links, P1 and P2 correspond to the fulcrum of the support, and S1 and S2 correspond to the cylinder. For convenience of explanation, the ball joint, the link and the cylinder are constituted by two sets, but in the embodiment, these are constituted by three sets. T corresponds to the antenna.

Here, although not shown in the drawing, the rotatable range of the members L2 and L3 is fixed. This corresponds to the fact that the ball joint is rotatable by the second installation groove. In view of these movements, when the S1 member and the S2 member are raised and lowered, the L1 member rotates in the drawing. At this time, when the ball joint, the link and the cylinder are constituted by three sets as in the embodiment, Can be adjusted in various ways. In this way, the antenna angle can be precisely and finely adjusted to a desired angle in the embodiment of the present invention.

The mounting apparatus 400 according to the embodiment of the present invention is connected to the inner circumferential surface of the opening 443 of the support unit 400 and is formed to be expandable and contractible to selectively press and fix the outer circumferential surface of the cylinder 460 And an interlock unit (not shown).

The interlock part may be formed in various structures such as a belt structure and an airbag structure. The interlocking part shrinks or expands when the angular position of the antenna 50 is to be fixed for a predetermined time or when the pregnant platform is to be abruptly started to compress and fix the cylinder 460 to thereby reduce the load on the driving part 470 .

For example, when the interlock portion is a belt structure, the interlock portion may include a plurality of seat belts and hoists formed to wind or unwind them. The seat belts are disposed across the opening 443 of the support 400 at a plurality of heights and are respectively in contact with the outer circumferential surface of the cylinder 460 and the ends thereof can be individually supported on the hoists. At this time, at least two seat belts per one cylinder are in contact with each other in different directions so as to exert forces in different directions on the cylinder, so that the outer peripheral surface of the cylinder can be pressed, It is possible to prevent unnecessary pressurization in the direction intersecting with the direction of the arrow. That is, when the seat belt is pulled by the hoists, it can prevent the movement of the cylinder while pressing the outer peripheral surface of the cylinder. Conversely, if the seat belts are disengaged from the hoists, the pressure contact with the cylinder can be released. The interlock part can tension the seatbelt by winding the seatbelt around the hoist, if necessary, and tightly pull the cylinder.

In the case where the interlock portion has an air bag structure, the interlock portion includes a plurality of elastic diaphragms, for example, spherical or ring-like elastic members, and these are disposed between the cylinders, respectively. Of course, the interlock part may have various configurations within a range that can perform the role.

The above-described embodiments of the present invention are for the explanation of the present invention and are not intended to limit the present invention. It should be noted that the configurations and the methods disclosed in the above embodiments of the present invention may be modified into various forms by combining or intersecting with each other, and such modifications may be considered within the scope of the present invention. That is, the present invention may be embodied in various forms within the scope of the claims and equivalents thereof, and it is possible for the technician skilled in the art to make various embodiments within the scope of the technical idea of the present invention. .
