Description

[Technical Field]

[0001] The present invention relates to an unmanned carrier antenna system, and more particularly to an unmanned carrier antenna system that suppresses enemy interference and improves the signal strength of the user's side. [Background technology]

[0002] An antenna is a device that transmits and receives radio frequency (RF) signals, radiating or coupling signals in the form of electromagnetic waves. During transmission, a transmitter applies an electric current to the antenna, which generates a radiating electromagnetic field through the applied time-varying voltage or current, converting the current energy into radio waves. During reception, an electric field induces a time-varying current within the antenna, generating a time-varying voltage at its end. The generated electrical signal is processed and can be observed or heard in a receiver. Traditional antennas are widely used in unmanned carrier communication systems.

[0003] Antennas are typically connected to a radio transmitter or receiver and are used to transmit and receive radio waves in an "omnidirectional" or "directional" manner, and are used as a kit to guide the direction of the radio waves. Most conventional unmanned carriers mainly use omnidirectional antennas, which can radiate uniformly in a flat plane. Omnidirectional antennas are also very easy to install, have a 360-degree horizontal radiation pattern, and can even be installed upside down on unmanned carriers. Summary of the Invention [Problem to be solved by the invention]

[0004] However, because unmanned carriers are operated remotely, signal reception from the unmanned carrier's omnidirectional antenna (Omni Antenna) is particularly important. Figure 1A is a schematic diagram showing a conventional unmanned vessel 10 and an omnidirectional antenna (Omni Antenna) 20. As shown in Figure 1B, all friendly central stations (O) communicate and operate via the unmanned carrier's omnidirectional antenna 20, which has a 360-degree horizontal radiation pattern. Therefore, when the unmanned carrier 10 approaches an enemy, the enemy may use a signal jammer to interfere. This could prevent the unmanned carrier 10 from receiving friendly signals, disrupting its connection with the friendly central station and resulting in the unmanned carrier 10 falling into enemy hands.

[0005] The main purpose of this invention is to solve the above-mentioned problems by providing an unmanned carrier antenna system that can block enemy interference signals and promote the effect of not affecting the communication of the user side, suppress enemy interference, and improve the signal strength of the user side.

[0006] Another object of the present invention is to provide an unmanned carrier antenna system that can increase the radiation efficiency of the unmanned carrier antenna, effectively expand the antenna coverage area, and improve communication quality by suppressing enemy interference and improving the signal strength of the user's side. [Means for solving the problem]

[0007] To achieve the above object, the unmanned carrier antenna system of the present invention, which suppresses enemy interference and improves the signal strength of the own side, comprises an unmanned carrier, a control module, and a power supply module. The unmanned carrier has at least one omnidirectional antenna mounted on the surface of the body. The control module is installed on the unmanned carrier and is used to control the power source to drive the unmanned carrier, and the control module is connected to the communication module and the omnidirectional antenna to control the operation of the unmanned carrier. The power supply module supplies the necessary power to the unmanned carrier and each device on the unmanned carrier. The omnidirectional antenna is installed on the surface of the main body so as to be upright, and the signal feed-in connected to the bottom and the coaxial cable is electrically connected to the ground interface. The unmanned carrier further includes a first metal plate, a second metal plate, a first braking module, and a second braking module. The first metal plate is installed in front of the omnidirectional antenna, and has a plurality of first air circulation holes on the surface of the plate, and a first earth wire is installed at the bottom, and the other end of the first earth wire is electrically connected to the ground interface, forming a shared ground state with the omnidirectional antenna. The second metal plate is installed behind the omnidirectional antenna, and has a plurality of second air circulation holes on the surface of the plate and a second earth wire installed at the bottom. The other end of the second earth wire is electrically connected to the ground interface, forming a shared ground state with the omnidirectional antenna. The first braking module includes a first braking member for connecting to the first metal plate, a first positioning member for positioning the first braking member, and a first driving source installed on the side of the first positioning member for driving the first braking member to make the first metal plate stand upright so as to shield the front of the omnidirectional antenna, or to fold the first metal plate onto the surface of the main body so that there is no shielding in front of the omnidirectional antenna. The second braking module includes a second braking member for connecting to the second metal plate, a second positioning member for positioning the second braking member, and a second driving source installed on the side of the second positioning member for driving the second braking member to make the second metal plate stand upright so as to shield the rear of the omnidirectional antenna, or to fold the second metal plate onto the surface of the main body so that there is no shielding behind the omnidirectional antenna. The control module further includes a navigation sensor module, a first braking module, and a second braking module electrically connected to the navigation sensor module, the navigation sensor module being used to provide position and heading information for the unmanned carrier. First, if the navigation sensor module detects the unmanned carrier in the "forward" state, The first braking module drives the first braking member so that the first metal plate stands upright to shield the front of the omnidirectional antenna and prevent interference signals from the enemy, and simultaneously drives the second braking member so that the second metal plate is folded flat on the surface of the body and does not shield the rear of the omnidirectional antenna. Next, if the navigation sensor module detects the unmanned carrier in a "returning" state, The first braking module drives the first braking member so that the first metal plate is folded flat on the surface of the body and does not block the front of the omnidirectional antenna, while the second braking module drives the second braking member so that the second metal plate is upright and blocks the rear of the omnidirectional antenna, preventing interference signals from the enemy. [Effects of the Invention]

[0008] The present invention is configured as described above and has the following advantages. First, while conventional unmanned carriers often use omnidirectional antennas for communication, in this invention, when the unmanned carrier 10 is "forward," the front is shielded with a metal plate to prevent signals from being radiated forward and to have no effect on communication between the unmanned carrier 10 and the friendly side. Conversely, when the unmanned carrier 10 is "returning," the rear is modified to be shielded with a metal plate to prevent signals from being radiated backward, thereby promoting the effect of suppressing interference signals from the enemy. Second, the metal plate of the present invention is provided with a plurality of air circulation holes 31, which has the effect of reducing the air resistance when the unmanned carrier 10 is navigating. Third, the metal plate of this invention not only suppresses interference signals from the enemy, but is also grounded together with the omnidirectional antenna 20, so that the metal plate also acts as an amplifier that radiates signals at the same time, improving the radiation efficiency of the antenna of the unmanned carrier 10, effectively expanding the antenna coverage range, and promoting the effect of improving the communication quality with the friendly side.

[0011] The present invention will be described below through embodiments of the invention, but the following embodiments do not limit the invention according to the scope of the utility model claims, and not all of the combinations of features described in the embodiments are necessarily essential to the solution of the invention.

[0012] First, an embodiment of the present invention will be described with reference to Figures 2 to 8. The first embodiment of the present invention comprises an unmanned carrier 10 having at least one omnidirectional antenna 20 installed on its body surface 11, a control module 60, and a power supply module 64. The control module 60 is installed on the unmanned carrier 10 and is used to control a power source 63 to drive the unmanned carrier 10, which power source 63 includes components such as a motor and an engine. The control module 60 is connected to a communication module 61 and the omnidirectional antenna 20 to control the operation of the unmanned carrier 10. The power supply module 64 supplies the necessary power to the unmanned carrier 10 and its respective devices. However, since the omnidirectional antenna 20, the control module 60, and the power source are all prior art, their description will be omitted here. In the following embodiments of the present invention, "F" refers to the front of the omnidirectional antenna 20, i.e., the front side of the unmanned carrier 10, and "R" refers to the rear of the omnidirectional antenna 20, i.e., the rear side of the unmanned carrier 10.

[0013] The present invention is characterized in that the omnidirectional antenna 20 is installed upright on the surface 11 of the main body, and the signal feed-in 21 at its bottom is electrically connected to the ground interface 40. In this embodiment, the ground interface 40 is in the form of a metal plate, but the present invention is not limited to this and may be a metal contact or a connecting conductor. Here, the signal feed-in 21 is an existing structure of the omnidirectional antenna 20 and is the connection point between the coaxial cable 22 and the omnidirectional antenna 20. The coaxial cable 22 is electrically connected to the communication module 61, but its description is omitted here.

[0014] The unmanned carrier further comprises the following components: A first metal plate (30F) is installed in front of the omnidirectional antenna (20), has a plurality of first air circulation holes (31f) on its surface, has a first earth wire (32f) installed on its bottom, and the other end of the first earth wire (32f) is electrically connected to the ground interface (40), forming a shared ground state with the omnidirectional antenna (20).

[0015] A second metal plate (30R) is installed behind the omnidirectional antenna (20), has a plurality of second air circulation holes (31r) on its surface, and has a second earth wire (32r) installed at its bottom. The other end of the second earth wire (32r) is electrically connected to the ground interface (40), forming a shared ground state with the omnidirectional antenna (20).

[0016] In this embodiment, the first metal plate 30F and the second metal plate 30R have the same structure, including, but not limited to, a flat plate 30a as shown in Fig. 6A. They may also be V-shaped 30b as shown in Fig. 6B, arc-shaped, or have other shapes (see Fig. 6C). The metal plate may be entirely made of metal, a composite of non-metallic plates, or an electroplated metal, all of which are possible.

[0017] Furthermore, regardless of the shape of the first metal plate 30F and the second metal plate 30R, a plurality of first air circulation holes 31f and second air circulation holes 31r are provided on the plate surfaces, which are used to reduce the resistance force when the unmanned carrier 10 moves forward.

[0018] 3A and 4A, the first braking module 50F includes a first braking member 51f connected to the first metal plate 30F, a first positioning member 52f for positioning the first braking member 51f, and a first driving source 53f. The first driving source 53f is installed on a side of the first positioning member 52f and drives the first braking member 51f to either stand upright so that the first metal plate 30F shields the front of the omnidirectional antenna 20, or fold it toward the main body surface 11 so that there is no obstruction in front of the omnidirectional antenna 20 (see FIGS. 3B and 4B).

[0019] 3B and 4B, the second braking module 50R has the same configuration as the first braking module 50F and is installed on the corresponding side to form a symmetrical configuration. That is, the second braking module 50R includes a second braking member 51r for connecting to the second metal plate 30R, a second positioning member 52r for positioning the second braking member 51r, and a second driving source 53r. The second driving source 53r is installed on the side of the second positioning member 52r and drives the second braking member 51r to either stand upright so that the second metal plate 30R shields the rear of the omnidirectional antenna 20, or fold it toward the main body surface 11 so that there is no shielding behind the omnidirectional antenna 20 (see FIGS. 3A and 4A).

[0020] In this embodiment, the first driving source 53f and the second driving source 53r are motors, but the present invention is not limited to this. They may also be rotary cylinders or pneumatic cylinders. These are mainly used to drive the first braking member 51f and the second braking member 51r to rotate by approximately 90 degrees on the main body surface 11, interlocking the first metal plate 30F and the second metal plate 30R.

[0021] In a preferred embodiment, the first braking member 51f and the second braking member 51r of the first braking module 50F and the second braking module 50R are shafts laterally connected to the bottom of the first metal plate 30F and the second metal plate 30R, and the first positioning member 52f and the second positioning member 52r are a pair of parallel bearings capable of supporting the shafts. The first driving source 53f and the second driving source 53r are installed on the sides of the first positioning member 52f and the second positioning member 52r and are capable of driving the first braking member 51f and the second braking member 51r to rotate forward and backward.

[0022] Furthermore, the first braking module 50F and the second braking module 50R can rotate the first metal plate 30F and the second metal plate 30R approximately 90 degrees back and forth to shield or not shield the omnidirectional antenna 20, but the present invention is not limited to this. For example, if the unmanned carrier 10 has a large interior space, the first braking module 50F and the second braking module 50R can raise the first metal plate 30F and the second metal plate 30R so that they are upright on the body surface 11 and shield the front or rear of the omnidirectional antenna 20. When folded, all of these variations are possible, such as lowering the first metal plate 30F and the second metal plate 30R into the interior space of the unmanned carrier 10.

[0023] 7, the control module 60 further includes a navigation sensor module 62, a first braking module 50F, and a second braking module 50R, which are electrically connected to each other. The navigation sensor module 62 is used to provide information on the position and heading of the unmanned carrier 10. Also referring to FIG. 8, the control flowchart of the first embodiment of the present invention includes the following steps: S100: Provide a first metal plate 30F and a second metal plate 30R. S110: Provide a navigation sensor module 62. S120: Determine whether the unmanned carrier 10 should "go forward" or "return." S130: When the navigation sensor module 62 detects that the unmanned carrier 10 is in the "forward" state, the first braking module 50F drives the first braking member 51f so that the first metal plate 30F stands upright and shields the front of the omnidirectional antenna 20, preventing interference signals from the enemy. Meanwhile, the second braking module 50R drives the second braking member 51r so that the second metal plate 30R is folded flat on the body surface 11, preventing the rear of the omnidirectional antenna 20 from being shielded. S140: When the navigation sensor module 62 detects the unmanned carrier's "returning" state, the first braking module 50F drives the first braking member 51f so that the first metal plate 30F is folded flat on the body surface 11 and does not block the front of the omnidirectional antenna 20. In addition, the second braking module 50R drives the second braking member 51r so that the second metal plate 30R is upright and blocks the rear of the omnidirectional antenna 20, preventing interference signals from the enemy.

[0024] Furthermore, in this embodiment, the length of the omnidirectional antenna 20 is preferably essentially 1 / 4 of its wavelength (λ). According to the basic principle of antenna transmission, electricity propagates through a conductor at nearly the speed of light. When it encounters a discontinuity in the conductor, it is reflected back to the signal source. If the current is alternating current and the reflected current is returned to the origin or feed point at the right time, the current strengthens with each subsequent cycle. Therefore, a standing wave can be maintained within the antenna with very little energy. The presence of a standing wave causes the antenna to resonate and emit radio waves into space. Based on transmission line theory and experimental evidence, an antenna with a length of 1 / 4 of the wavelength of a wireless electrical signal has high transmission and reception conversion efficiency. Compared to a 1 / 2 wavelength, a full-wave antenna requires a much smaller antenna size. Therefore, a 1 / 4 wavelength antenna is commonly used because it offers the highest transmission and reception efficiency relative to the antenna size.

[0025] The length of the omnidirectional antenna 20 is 1 / 4 of the wavelength (λ), and the heights of the first metal plate 30F and the second metal plate 30R are the same as or slightly longer than the length of the omnidirectional antenna 20. In this way, interference signals from other parties to the omnidirectional antenna 20 can be prevented.

[0026] The second embodiment of the present invention, shown in Figures 9A to 13, is designated by the same reference numerals as the first embodiment. While the first embodiment has two metal plates, a first metal plate 30F and a second metal plate 30R, the second embodiment differs from the first embodiment in that it has only one metal plate, i.e., an upright metal plate 30. As described in the previous embodiments, the upright metal plate 30 may be a flat plate 30a, a V-shaped plate 30b, an arc-shaped plate 30c, or other shapes. In this embodiment, the arc-shaped plate 30c will be used as an example. Furthermore, the second embodiment requires only one damping module 50, which moves the upright metal plate 30 to a position in front of or behind the omnidirectional antenna 20.

[0027] According to the second embodiment of the present invention, the overall structure includes the following components: The configuration of each component will be described below.

[0028] An upright metal plate 30 is installed around the periphery of the omnidirectional antenna 20, has a plurality of air circulation holes 31 on its surface, has an earth wire 32 installed at its bottom, and the other end of the earth wire 32 is electrically connected to a ground interface 40, forming a shared ground state with the omnidirectional antenna 20.

[0029] A braking module (50) comprising: a braking member (51) used for connecting to the upright metal plate (30); a positioning member (52) for positioning the braking member (51); and a driving source (53) installed on the side of the positioning member (52) and used to drive the braking member (51) so that the upright metal plate (30) assumes an upright shape to shield the front or rear of the omnidirectional antenna (20).

[0030] 12, the control module 60 further includes a navigation sensor module 62, a first braking module 50F, and a second braking module 50R, which are electrically connected to each other. Referring to FIG. 13, a control flowchart according to the second embodiment of the present invention includes the following steps: S200: Provide an upright metal plate 30. S210: Provide a navigation sensor module 62. S220: Determine whether the unmanned carrier 10 should "go forward" or "return." S230: When the navigation sensor module 62 detects that the unmanned carrier 10 is in the "forward" state, the braking module 50 drives the braking member 51 so that the upright metal plate 30 assumes an upright position to shield the front of the omnidirectional antenna 20, thereby preventing interference signals from the enemy and not shielding the rear of the omnidirectional antenna 20. S240: When the navigation sensor module detects the unmanned carrier in a "returning" state, the braking module 50 drives the braking member 51 so that the upright metal plate 30 assumes an upright position to shield the rear of the omnidirectional antenna 20, thereby preventing interference signals from the enemy.

[0031] In a preferred embodiment, the upright metal plate 30 includes an arc shape, and both sides of the arc shape do not exceed the 180 degree line.

[0032] In a preferred embodiment, the braking member 51 of the braking module 50 is a ring gear, and the bottom of the upright metal plate 30 is connected to the upper edge surface of the braking member 51. The positioning member 52 is a ring groove capable of supporting the braking member 51 for rotation thereon. The driving source 53 is installed on the side of the positioning member 52, and its shaft 531 is provided with a small gear 532 that meshes with the braking member 51, so as to drive the braking member 51 to rotate forward and backward. In this embodiment, the ring gear is shown as an annular internal gear, but the present invention is not limited thereto. The ring gear may also be an annular external gear, in which case the driving source 53 and the small gear 532 are installed on the outer periphery of the annular external gear but are not meshed therewith.

[0033] Therefore, the second and first embodiments of the present invention both have substantially the same effect of suppressing interference signals from the enemy and simultaneously strengthening the signal radiation of the antenna.

[0034] Although the embodiment of the present invention has been described above in detail with reference to the drawings, the specific configuration is not limited to this embodiment, and design modifications and the like are also included within the scope of the present invention without departing from the gist of the present invention.
