Description

Technical Field

[0001] The present application relates to the technical field of satellite-borne reflector installation and adjustment, and in particular to a satellite-borne reflector antenna adjustment and control system. Background Art

[0002] With the advancement of science and technology and human exploration of space, the requirements for spacecraft will become higher and higher. Antennas are devices for receiving and transmitting spacecraft signals, and everyone is familiar with them, but satellite-borne reflector antennas are unfamiliar to most people. Satellite-borne reflector antennas are mainly composed of feed sources, main reflectors, sub-reflectors, and related structural supports. As for the relative spatial position accuracy between the main reflector, sub-reflector, and feed source, since the feed source and sub-reflector are rigidly fixed by a metal frame, only the spatial position accuracy between the main reflector and the sub-reflector needs to be considered. The main reflector is much smaller than the sub-reflector, and is mainly fixed above the main reflector by multiple support rods and their auxiliary parts.

[0003] Due to a series of reasons such as the material, strength, and size of the support rod, the spatial accuracy of the main reflector above will be relatively poor after normal assembly, and the maximum error can reach 1 mm, which is far from the accuracy requirement. However, the actual situation is that if the main reflector is to meet the spatial accuracy requirements, it is necessary to ensure that the accuracy of the support is ±2 microns, or directly form the entire carbon fiber composite, which is costly and cannot be adjusted, and must be successful in one go. Otherwise, when assembling the main and secondary reflectors, the spatial accuracy of the main reflector can only be adjusted by constantly repairing and reworking the support parts, which is time-consuming and labor-intensive and may not necessarily guarantee quality. In order to reduce the difficulty of installing and adjusting the main reflector in the satellite-borne reflector antenna and save production and manufacturing costs. Summary of the invention

[0004] The purpose of this application is: to solve the above-mentioned technical problems, this application provides a satellite-borne reflector antenna adjustment control system, aiming to improve the adjustment efficiency of the main reflector in the satellite-borne reflector antenna.

[0096] Specifically, the first driving module and the second driving module are preferably external driving motors for controlling the rotation speed and rotation direction of the second adjusting rod of the first adjusting rod 310 .

[0097] Specifically, the adjustment parameters are set, including:

[0104] Specifically, the adjustment sequence is set according to the first-level initial difference, including:

[0105] Preset the first-level difference threshold;

[0106] If the level one initial difference is greater than the preset level one difference threshold, the adjustment order is set to the first adjustment order;

[0107] If the first-level initial difference is less than the preset first-level difference threshold, the adjustment sequence is set to the second adjustment sequence.

[0108] Specifically, the first adjustment sequence refers to first performing Y-direction adjustment and then performing X-direction adjustment, and the second adjustment sequence refers to performing X-direction adjustment only.

[0109] Specifically, setting the rotation speed v1 of the first adjusting rod according to the primary difference includes:

[0110] Preset the first level difference interval (A1, A2), the second level difference interval (A2, A3) and the third level difference interval (A3, A4);

[0111] Get the real-time first-level difference a;

[0112] When the real-time primary difference a is within the preset first primary difference interval, the rotation speed v1 of the first adjustment lever is set to the first rotation speed V1, ie, v1 = V1;

[0113] When the real-time primary difference a is within the preset second primary difference interval, the rotation speed v1 of the first adjustment lever is set to the second rotation speed V2, ie v1 = V2;

[0129] Specifically, the value range between the first reference evaluation value and the second reference evaluation value is the same. The larger the first initial difference, the larger the corresponding first reference evaluation value. The larger the secondary initial difference, the larger the corresponding second reference evaluation value. The larger the operating evaluation value, the larger the distance that the current main reflecting surface needs to be adjusted.

[0130] Specifically, when the compensation coefficient m is set according to the adjustment evaluation value c, it includes:

[0131] Presetting a first adjustment evaluation value interval (C1, C2), a second adjustment evaluation value interval (C2, C3) and a third adjustment evaluation value interval (C3, C4);

[0137] Specifically, in the above embodiment, the corresponding compensation coefficient is set according to the operation evaluation value, so as to dynamically adjust the rotation speed between the first adjustment rod 310 and the second adjustment rod, thereby ensuring the efficiency of adjusting the position of the main reflection surface, saving installation time and reducing the overall production cost.

[0138] In a preferred embodiment of the present application, the support portion includes:

[0139] A first support member 410, a second support member 420, a third support member 430 and a fourth support member 440;

[0140] The first support member 410 includes:

[0141] A support base 415, used for connecting the secondary reflector;

[0142] A lower support rod 412, one end of which is connected to a support seat 415;

[0145] Specifically, the first support member 410 , the second support member 420 , the third support member 430 and the fourth support member 440 have the same structure.

[0146] Specifically, the lower support rod 412, the telescopic rod 413, the upper support rod 411 and the connecting and fixing block 414 cooperate to set up the main fixing seat 100. Through the threaded connection of the telescopic rod 413 and the lower support rod 412, without considering the processing accuracy of the supporting components on the outside of the main fixing seat 100, the vertical height of the main fixing seat 100 is adjusted by rotating the adjusting rod through the matching margin between the structures, so as to compensate the installation accuracy of the main reflecting surface along the Z-axis direction with the processing accuracy. The height of the main reflecting surface along the Z-axis direction can be controlled within the accuracy requirement of ±0.03 mm. Compared with the traditional control of the accuracy of the support parts or the integral molding of the carbon fiber composite material that must be successfully completed in one time, the production is more cost-effective and it is easier to control the installation accuracy of the main reflecting surface along the Z-axis direction.

[0147] According to the first concept of the present application, by adding an X-axis adjustment part, a Y-axis adjustment part and adding a telescopic rod between the upper support rod and the lower support rod, the spatial position adjustment of the main reflector is achieved, and the position of the main reflective surface is adjusted to a position that meets the spatial accuracy requirements. Compared with the installation of the main reflective surface with a fixed structure, the error reaches a defect of 1 mm. The installation of the main reflective surface can be controlled within the accuracy requirement of ±0.03 mm.

[0148] According to the second concept of the present application, by adding a driving unit, the driving unit is connected after the main reflector is initially installed, and the movement of the X-axis adjustment unit and the Y-axis adjustment unit is accurately controlled according to the preset working parameters, thereby improving the installation and adjustment efficiency of the main reflector, saving manufacturing costs and ensuring assembly accuracy.

[0149] The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present application. These improvements and substitutions should also be regarded as the scope of protection of the present application.
