Description

Technical Field

[0001] The present invention relates to the technical field of Ku and Ka dual - frequency, and specifically to a rapid switching device for Ku and Ka dual - frequency transceiver components. Background Technique

[0002] In recent years, high - throughput satellites have developed rapidly. For example, in China's two recent high - throughput satellites, the Ku or Ka frequency band is often used. Among them, Zhongxing 16 satellite was launched on April 12, 2017. The small station uses the Ka frequency band, is fixed at the geostationary satellite orbit at 110.5 degrees east longitude, provides 26 user beams, covers China and its offshore areas, and can be applied to fields such as distance education, medical treatment, Internet access, airborne and ship communication, and emergency communication. AsiaSat 6D satellite was successfully launched on July 9, 2020. The small station of AsiaSat 6D communication satellite uses the Ku frequency band for transmission. The total communication capacity reaches 50 Gbps, and the single - beam capacity can reach more than 1 Gbps, which can provide high - quality voice and data communication services for users; with 90 user beams, it realizes global coverage within the visible range.

[0003] Since the performances of the two high - throughput satellites are different at different times and in different regions, there may be a situation where one option is more optimal at a certain time. Moreover, for different satellites, the access effects for different industry users are different. Under applicable circumstances, customers may switch different satellites to achieve the maximum utilization of a set of equipment.

[0004] In the current technical state, Ku / Ka can be reused. For users, it saves the investment in fixed assets, increases the applicable range of the equipment, and has a competitive advantage.

[0005] The previous technical solution was to adopt the scheme of sharing a feed for Ku / Ka. However, in the design, sharing a feed will lead to a reduction in efficiency, and the transceiver also needs to be replaced.

[0006] Similar technical solutions also include the scheme of replacing the feed rod together with the transceiver. However, the disadvantage is that the polarization cannot be automatic, which increases the inconvenience for customers to use. Summary of the Invention

[0007] The purpose of the present invention is to provide a rapid switching device for Ku and Ka dual - frequency transceiver components to solve the problems raised in the above - mentioned background technique.

[0008] To achieve the above object, the present invention provides the following technical solution: A fast switching device for a ku and ka dual-frequency transceiver module, including a base, an azimuth electrical compartment arranged on the base, an external battery and an elevation electrical compartment arranged on the azimuth electrical compartment, and an antenna surface and a polarization rotation component arranged on the elevation electrical compartment.

The ku feed rod fastener and the ku transceiver fastener can be respectively fixed at both ends of the ku circular waveguide extension by matching the protrusions and the grooves, for the purpose of achieving a tight fit. And when the polarization is switched, the ku transceiver is driven by the polarization rotation motor, thereby realizing the automatic switching of the polarization.

[0010] Preferably, one end of a ka circular waveguide converter passing through the antenna surface is provided with a ka feed rod, and the other end is provided with a ka transceiver.

[0011] Preferably, both ends of the ka circular waveguide converter are fixed with protrusions, and grooves adapted to the protrusions are respectively formed in the ka feed rod fastener and the ka transceiver fastener. The ka feed rod fastener and the ka transceiver fastener can be respectively fixed at both ends of the ka circular waveguide converter by matching the protrusions and the grooves. The ka transceiver fastener is fixedly connected to a ka quadrature coupler, and the ka transceiver contacts and can rotate with the ka quadrature coupler. In addition to reducing the circular waveguide gap and reducing microwave loss, this cooperation can fix the ka quadrature coupler part with the ka feed rod fastener, the ka transceiver fastener, and the ka circular waveguide converter. And when the polarization is switched, the ka quadrature coupler is fixed, and the ka transceiver is driven by the polarization rotation motor, thereby realizing the automatic switching of the polarization.

[0012] Preferably, the polarization rotation component includes a polarization rotation motor, a belt, a synchronous pulley, a soft limit switch, a polarization hard limit A, a polarization hard limit B, and a limit piece.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] It is convenient and quick to switch between Ku / Ka frequency bands, while retaining the automatic polarization satellite alignment rotation, ensuring that the overall weight of the device is relatively light and easy to use. However, if the polarization of the Ku frequency band needs to be adjusted manually, each time it is necessary to log in to the device wirelessly or wired to check the current polarization angle; or manually switch after finding the polarization angle through the screen, making the device very inconvenient to use.

When using a ku satellite, it is necessary to install a ku feed 1, fix the ku feed rod 1 to the antenna surface 2 through the ku feed rod fastener 7, connect the ku feed rod 1 to the ku circular waveguide extension 9, and then connect the ku circular waveguide extension 9 to the pitch electrical compartment 6 through the ku transceiver 3. The polarization rotation motor 1601 of the polarization rotation assembly 16 is fixed to the azimuth electrical compartment 5 by bolts.

[0026] Embodiment Two

[0027] As shown in the attached Figure 5 and Figure 6As shown in the figure, the present invention provides a technical solution: a fast switching device for a Ka-band transceiver module, which includes a Ka feed rod 11, a Ka transceiver 12, a Ka feed rod fastener 13, a Ka transceiver fastener 14, and a Ka circular waveguide converter 15. One end of the Ka circular waveguide converter 15 passing through the antenna surface 2 is provided with a Ka feed rod 11, and the other end is provided with a Ka transceiver 12. Both ends of the Ka circular waveguide converter 15 are fixed with protrusions. Grooves adapted to the protrusions are respectively formed in the Ka feed rod fastener 13 and the Ka transceiver fastener 14, and the Ka feed rod fastener 13 and the Ka transceiver fastener 14 can be respectively fixed to both ends of the Ka circular waveguide converter 15 in cooperation with the protrusions and the grooves. The Ka transceiver fastener 14 is fixedly connected to the Ka ortho-coupler, and the Ka transceiver 12 is in contact with the Ka ortho-coupler and can rotate. In addition to reducing the circular waveguide gap and microwave loss, this cooperation can fix the Ka ortho-coupler part to the Ka feed rod fastener 13, the Ka transceiver fastener 14, and the Ka circular waveguide converter 15. And when the polarization is switched, the Ka ortho-coupler is fixed, and the Ka transceiver 12 is driven by the polarization rotation motor 1601, so as to realize the automatic switching of polarization. The Ka feed rod fastener 13 and the Ka transceiver fastener 14 can be respectively fixed to both ends of the Ka circular waveguide converter 15 in cooperation with the protrusions and the grooves. When it is necessary to use the Ka satellite, it is necessary to install the Ka feed rod 11, fix the Ka feed rod 11 to the antenna surface 2 through the Ka feed rod fastener 13, connect the Ka feed rod fastener 13 to the Ku circular waveguide extension, and insert the Ka circular waveguide converter 15 in the middle of the Ku circular waveguide extension to change its waveguide aperture, so as to realize the transmission of Ka-band electromagnetic waves. Behind the Ku circular waveguide extension, it is necessary to connect the Ka transceiver 12 to the elevation electrical compartment 6 through the Ka transceiver fastener 14.

[0028] As Figure 4As shown, as a preferred embodiment, on the basis of the above method, further, the polarization rotation assembly 16 includes a polarization rotation motor 1601, a belt 1602, a synchronous pulley 1603, a soft limit switch 1604, a polarization hard limit A 1605, a polarization hard limit B 1606, and a limit piece 1607. One end of the belt 1602 is sleeved on the output end of the polarization rotation motor 1601, and the other end is sleeved on the outside of the synchronous pulley 1603. The polarization hard limit A 1605, the polarization hard limit B 1606, and the limit piece 1607 are fixed to the pitching electrical bin 6 by bolts. A soft limit switch 1604 is provided on the limit piece 1607. When the polarization rotates, the polarization rotation motor 1601 drives the synchronous pulley 1603 to rotate through the belt 1602, making the limit piece 1607 and the soft limit switch 1604 sense each other. The software will sense the current position and set the current position to calibrate it. The polarization hard limit A 1605 and the polarization hard limit B 1606 limit its position to avoid exceeding the range. Since the ku device is linearly polarized, the polarization angle is changed by the movement of the ku transceiver 3 relative to the ground level. When the polarization rotates, the entire ku transceiver 3 will be fixedly connected to the synchronous pulley 1603, driving the angle change of the ku transceiver 3 to achieve the automatic rotation of linear polarization.

[0029] Since the ka device is circularly polarized, the left - hand and right - hand rotations are switched through the quadrature coupler inside the ka transceiver 12. When its internal paddle is installed and fastened, it is connected through the ka circular waveguide converter 15. The internal rotation mechanism of the quadrature coupler of the ka transceiver 12 is fixed to the ka circular waveguide converter 15. When the polarization is switched, the quadrature coupler is fixed, and the ka transceiver 12 is driven by the polarization rotation motor 1601, thus realizing the automatic switching of polarization.

[0030] The working principle of this ku and ka dual - frequency transceiver assembly fast - switching device:

[0031] When the ku satellite needs to be used, the ku feed 1 needs to be installed. The ku feed rod 1 is fixed to the antenna surface 2 through the ku feed rod fastener 7, and the ku feed rod 1 is connected to the ku circular waveguide extension 9. Then, the ku circular waveguide extension 9 is connected to the elevation electrical compartment 6 through the ku transceiver 3. When the polarization rotates, the polarization rotation motor 1601 drives the synchronous pulley 1603 to rotate through the belt 1602, and the limit piece 1607 is sensed by the soft limit switch 1604. The software will sense the current position and set the current position to calibrate it. The polarization hard limit A 1605 and the polarization hard limit B 1606 limit its position to avoid exceeding the range. Since the ku device is linearly polarized, the polarization angle is changed by the movement of the ku transceiver 3 relative to the ground level. When the polarization rotates, the entire ku transceiver 3 is fixedly connected to the synchronous pulley 1603, driving the angle change of the ku transceiver 3 to achieve the automatic rotation of linear polarization;

[0032] When the ka satellite needs to be used, the ka feed rod 11 needs to be installed. The ka feed rod 11 is fixed to the antenna surface 2 through the ka feed rod fastener 13, and the ka feed rod fastener 13 is connected to the ku circular waveguide extension. And in the middle of the ku circular waveguide extension, the ka circular waveguide converter 15 is inserted to change its waveguide aperture, so as to realize the transmission of ka-band electromagnetic waves. Behind the ku circular waveguide extension, the ka transceiver 12 needs to be connected to the elevation electrical compartment 6 through the 1 ka transceiver fastener 14. Since the ka device is circularly polarized, the left-handed and right-handed switching is realized through the quadrature coupler inside the ka transceiver 12. When its internal dial is installed and fastened, it is connected through the ka circular waveguide converter 15. The internal rotation mechanism of the quadrature coupler of the ka transceiver 12 is fixed to the ka circular waveguide converter 15. When the polarization is switched, the quadrature coupler is fixed, and the ka transceiver 12 is driven by the polarization rotation motor 1601, so as to realize the automatic switching of polarization.
