Method and device for layered priority control of high and low space remote sensing positioning servo of satellite communication

Abstract

The invention discloses a method and device for hierarchical priority control of satellite communication high and low altitude remote sensing positioning servo, including an antenna control unit, an azimuth drive unit, a pitch drive unit, a drive control and a power distribution unit, and is characterized in that it also includes a communication upper remote control Unit and portable control unit, the beneficial effect is that the layered thinking is clear, and the priority processing provides the basis for each device to work independently. Once a misoperation occurs, it can be covered by a high-level control method, and the safety and reliability are significantly improved, especially the CCU. The system is placed near the central body of the antenna, and the operator can cut off any abnormal conditions at any time.

Description

technical field [0001] The invention belongs to the field of satellite communication remote sensing positioning and tracking, and in particular relates to the layered priority for satellite communication ground stations to enable antennas to perform remote sensing positioning and tracking of high and low altitude satellites in L, C, Ku, Ka, and millimeter wave space microwave communication systems Control devices and methods. Background technique [0002] The satellite communication ground station is an important system in the field of satellite communication. Whether it is a synchronous satellite or an asynchronous satellite, due to the influence of the irregular distribution of the earth's gravity field and the influence of solar wind pressure on the satellite, the position of the satellite in the orbit changes slowly. Therefore, the on-board command equipment can be used to drive the jet propulsion according to the instructions sent by the measurement and control station ...

AI Technical Summary

Problems solved by technology

The azimuth motor, pitch motor and position sensor are traditional electromechanical components with good reliability, while some hardware and software components of the antenna control unit, drive unit and protection unit are more easily affected by the environment. Once a problem occurs in a certain link, The whole system will be paralyzed

[0005] 2. During the installation and commissioning of general ground stations, it is necessary to carry out on-site structural assembly of the antenna system, especially the mechanical transmission part. The existing positioning control device does not consider placing control equipment on the antenna. The assembly and adjustment of the entire antenna structure is very inconvenient and serious. Affects working hours and cannot solve the emergency adjustment problem at all

The overall debugging is generally placed on the antenna system site. It is inconvenient if there is no corresponding control equipment on site. If the overall debugging is placed outside the antenna system site, the signals of each band of the antenna will lose their authenticity due to signal loss.

[0006] 3. Even if all the equipment is in place, according to the design principle of the ground station, the positioning control part is placed in the control room, which is far away from the outdoor part of the antenna, generally 100 meters to 200 meters away. This kind of indoor debugging cannot observe the outdoor antenna. sports scene

Even when the surface of the antenna pot is cracked, the limit impact, the damage to the buffer and the serious damage to the mechanical transmission parts, etc., it will constitute a major failure problem for medium and large ground stations.

[0007] 4. At present, the design idea of ​​the protection unit is to only set up a set of protection circuits, and then send the protection signal to each unit to deal with the corresponding failure after comprehensive analysis of the faults of each part. The problem brought about is that the protection is not timely, and even causes undue heavy loss

[0008] 5. This technology is composed of many circuit boards, which is bulky, complicated wiring, inconvenient maintenance, and increases the complexity of the positioning control system
