Description

Technical Field

[0001] The utility model relates to the technical field of antennas, in particular to an autonomous star-pointing device for a satellite antenna. Background Art

[0002] The satellite antenna is the front end of satellite signal reception. Only by accurately adjusting the antenna to the appropriate elevation and azimuth angles can satellite signal reception be maximized. By calculating the latitude and longitude of the signal reception location and the longitude of the geostationary satellite positioning system, the exact position and angle of the satellite antenna receiving geostationary satellite signals can be determined. Therefore, auxiliary tools are necessary to adjust the installation position of the satellite antenna to optimize satellite signal reception.

[0003] Chinese patent publication number CN203180082U discloses a satellite antenna adjustment assist device, comprising an elevation alignment device, an azimuth alignment device, and a fixing device. The elevation alignment device includes an elevation reading disk and a laser pointer, which is rotatably fixed to the center of the elevation reading disk via a fixing knob. The azimuth alignment device includes a compass and its connector. The fixing device is fixed perpendicularly to the elevation alignment device through the center of the elevation reading disk, and the compass is fixed parallel to the fixing device. This assists in accurately positioning and aligning the satellite antenna, while also being low-cost and easy to operate.

[0004] The above patent has the following problems during implementation: adjusting the elastic connecting rod up and down to keep the compass in a horizontal state, reading the compass value, and continuously adjusting the azimuth of the antenna until the compass reading matches the specified azimuth; finally, adjusting the elevation of the satellite antenna up and down, and reading the angle between the connecting line between the laser pointer, the heavy hammer and the fixed knob through the protractor (elevation reading disk), which is the elevation of the satellite antenna; continuously adjusting the elevation of the antenna until the angle read by the elevation reading disk matches the specified elevation - it can be seen that the above patent manually operates the entire process of adjusting the satellite antenna for accurate positioning and precise star alignment, which is time-consuming and labor-intensive, and there will still be certain deviations in the process of manually adjusting the azimuth of the antenna, which is not as accurate as automatic star alignment.

They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed, or operate in a specific direction, and therefore should not be construed as limiting this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0033] Example:

[0034] like Figure 1-4 As shown, a satellite antenna autonomous pointing device includes a signal acquisition position marking device 1, a signal acquisition unit 2, an information acquisition and processing module 7, an antenna position driving module 8 and a satellite antenna 9.

[0035] The signal acquisition position marking device 1 is composed of a plurality of spherical honeycomb signal acquisition units 2. The honeycomb signal acquisition unit 2 includes wave absorbing blades 4 and a satellite signal sensor 5. The signal acquisition unit 2 is surrounded by the wave absorbing blades 4.

[0036] The absorbing blade 4 includes a bottom blade 41 and a side blade 42. The side blade 42 is fixedly provided on the upper end of the bottom blade 41 in the circumferential direction; and the satellite signal sensor 5 is fixedly provided on the bottom blade 41.

[0037] The material of the absorbing blade 4 is a single-layer flat graphene, which has a wave absorbing function and can prevent the satellite signal from being reflected and causing erroneous collection, thereby affecting the collection accuracy.

[0038] The absorbing blade 4 is a pentagonal or hexagonal structure with an internal and top opening. The cross section of the side blades 42 of the absorbing blade 4 is a pentagon or hexagon. The length of the bottom blade 41 of the absorbing blade 4 is less than the length of the top opening of the absorbing blade 4.

[0039] The length ratio of the bottom blade 41 of the absorbing blade 4 to the top opening length of the absorbing blade 4 is 3 / 4 to 1. The reason for setting the length ratio to 3 / 4 to 1 is that if the length ratio is less than 3 / 4, the top opening of the absorbing blade 4 is too large, which will affect the sensitivity of the values ​​of the adjacent satellite signal sensor 5 and is not conducive to positioning.

[0040] The diameter of the satellite signal sensor 5 is not less than 1 / 2 of the length of the bottom blade 41 of the absorbing blade 4. If it is less than 1 / 2, the signal receiving area is too small, affecting the strength of satellite signal reception.

[0041] The satellite signal sensor 5 and the information acquisition and processing module 7 are electrically connected via a cable 6; the information acquisition and processing module 7 and the antenna position drive module 8 are electrically connected via a cable 6; the antenna position drive module 8 and the satellite antenna 9 are connected; the antenna position drive module 8 drives the satellite antenna 9 to rotate to adjust the position and accurately align the satellite.

[0042] A bracket 3 is fixedly provided at the lower end of the signal acquisition position marking device 1 .

[0043] The information collection and processing module 7 includes a satellite signal collector 71, an encoder 72, a programmable logic controller PLC 73 and a first power supply 74;

[0044] The satellite signal collector 71 is electrically connected to the satellite signal sensor 5; the satellite signal collector 71 is electrically connected to the encoder 72; the encoder 72 is electrically connected to the programmable logic controller PLC73; the first power supply 74 is electrically connected to the satellite signal collector 71, the encoder 72, and the programmable logic controller PLC73 respectively.

[0045] The programmable logic controller PLC 73 can be a conventional programmable logic controller PLC. The first power supply 74 can be a conventional power supply.

[0046] The satellite signal collector 71 may be an OHR-PR30 data collector, but is not limited to this model.

[0047] The encoder 72 may be SN74HC148DR, but is not limited to this model.

[0048] The antenna position driving module 8 includes a satellite signal receiver 81 , a motor driving controller 82 , a first stepper motor 83 , a second stepper motor 84 , and a second power supply 85 .

[0049] The satellite signal receiver 81 is electrically connected to the programmable logic controller PLC 73. The satellite signal receiver 81 is electrically connected to the motor drive controller 82. The motor drive controller 82 is electrically connected to the first stepper motor 83 and the second stepper motor 84. A second power supply 85 is electrically connected to the satellite signal receiver 81, the motor drive controller 82, the first stepper motor 83, and the second stepper motor 84.

[0050] The first stepper motor 83 drives the satellite antenna 9 to rotate in the longitude direction; the second stepper motor 84 drives the satellite antenna 9 to rotate in the latitude direction.

[0051] The first stepper motor 83 and the second stepper motor 84 can be conventional stepper motors, and the second power supply 85 can be conventional power supply.

[0052] The satellite signal receiver 81 may be an OHR-R40 data receiving control device, but is not limited to this model.

[0053] The motor drive controller 82 may use a HCTL-1100 control chip, but is not limited to this model.

[0054] Working principle:

[0055] After the Satellite World autonomous star pointing device 1 is turned on, the target satellite signal will always be captured by the signal collection unit 2 on one side of the device due to its spherical array design. The signal of the collection unit facing the satellite is the strongest. The signals collected by the collection units in the other areas will gradually weaken as the angle deviates. The signal of the collection unit facing away from the satellite is the weakest.

[0056] The satellite signal sensor 5 may use a BCM4500KQM chip, and transmits all satellite signals collected in real time and marked with signal strength and location to the information collection and processing module 7 via a cable 6. The satellite signal collector 71 collects and stores the signals and converts them into digital signals.

[0057] The satellite signal collector 71 transmits the digital signal to the encoder 72, which encodes the signal to form a signal source that can be recognized by the editable logic controller 73;

[0058] The encoder 72 transmits the signal source identified by the editable logic controller 73 to the programmable logic controller PLC73. After receiving the signal source, the programmable logic controller PLC73 finally converts the signal source into a latitude and longitude coordinate signal with a spatial position mark and outputs it to the antenna position driving module 8.

[0059] After receiving the longitude and latitude coordinate signals with spatial position marks, the satellite signal receiver 81 transmits them to the drive controller 83; the drive controller 83 loads the received longitude and latitude coordinate signals with spatial position marks into the first stepper motor 83 and the second stepper motor 84 respectively. The first stepper motor 83 controls the satellite antenna to rotate in the longitude direction, and the second stepper motor 84 controls the satellite antenna to rotate in the latitude direction, realizing the rotation of the two motors, driving the antenna to achieve a 360° rotation angle, thereby driving the satellite antenna 9 to adjust its attitude and accurately point to the satellite.

[0060] When the satellite antenna is offset from the star, the satellite antenna autonomous star device will sense it in time and adjust the satellite antenna position in real time through the above steps.

[0061] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
