Abstract
Description
Technical Field
[0001] This utility model relates to the field of data receiving station technology, specifically to an AEC type shipborne data receiving station system. Background Technology
[0002] Shipborne data receiving stations are mainly used at sea to stably receive, process, and forward data signals transmitted by satellites. However, because ships are in the ocean environment for a long time, the high salinity and high humidity of the sea air continuously act on metal and electronic components, causing materials to gradually deteriorate and even malfunction. This can easily reduce the lifespan of the servo system and, to some extent, affect data reception. Utility Model Content
[0003] The purpose of this invention is to provide an AEC-type shipborne data receiving station system to solve the above problems. The shipborne station adopts an azimuth-elevation-cross triaxial antenna mount and a program tracking system, which can ensure that the antenna is effectively isolated from the ship's movement and that the antenna beam is always accurately pointed to the target satellite.
[0004] This utility model achieves the above objectives through the following technical solutions:
[0005] An AEC-type shipborne data receiving station system includes a support plate, an antenna radome, a first support mechanism, a second support mechanism, a third support mechanism, and an antenna mechanism. The third support mechanism is connected to the antenna mechanism. The support plate is equipped with a power distribution unit, a control microcomputer, and a servo control box. A protective shell is bolted to the top side of the support plate. The antenna radome and the support plate are bolted together. A support column is bolted to the bottom side of the support plate.
[0006] The support plate and the first support mechanism are connected to each other through an azimuth seat. The first support mechanism is equipped with an azimuth transmission chain by bolts. The azimuth transmission chain and the azimuth seat are connected to each other through a transmission mechanism. The azimuth seat and the azimuth protection mechanism are connected to each other through a transmission mechanism. The azimuth protection mechanism is connected to the first support mechanism. The first support mechanism and the second support mechanism are connected to each other through a pitch transmission chain. The second support mechanism and the third support mechanism are connected to each other through a cross C-axis transmission chain.
[0007] Furthermore, the first support mechanism includes a pitch frame, which is rotatably mounted on the top side of the azimuth base. The transmission mechanism includes a large gear, a first gear, and a second gear. The large gear is fixedly mounted on the outside of the azimuth base, and the first gear is fixedly mounted on the output end of the azimuth transmission chain. The azimuth protection mechanism includes an azimuth gyroscope, an azimuth limit switch, and an azimuth zero-crossing switch. The second gear is connected to the azimuth gyroscope, which is rotatably mounted on the top side of the pitch frame.
[0008] Furthermore, the large gear, the first gear, and the second gear mesh with each other.
[0009] Furthermore, the azimuth limit switch is bolted to the top side of the pitch frame, and the azimuth zero-crossing switch is bolted to the top side of the pitch frame.
[0010] Furthermore, a pitch limit switch is bolted to the outside of the pitch frame.
[0011] Furthermore, the second support mechanism includes a first bracket, inside which a baseband is bolted and connected to the power amplifier, and a cross C-axis limit switch is bolted on the front side of the first bracket.
[0012] Furthermore, the third support mechanism includes a second bracket, and a downconverter is bolted to the outside of the second bracket. The antenna mechanism includes an antenna surface and a feed assembly.
[0013] Furthermore, the feed assembly is connected to the second bracket by bolts, and the feed assembly abuts against the antenna surface.
[0014] Furthermore, the antenna surface adopts a carbon fiber honeycomb sandwich structure.
[0015] Furthermore, the bolt is made of stainless steel.
[0016] Using the above structure, firstly, the shipborne data receiving station, according to the mission plan, uses an azimuth-elevation-cross triaxial antenna mount and a program tracking system to ensure that the antenna beam is always accurately pointed at the target satellite, providing a reliable data receiving link for the channel equipment. After initial acquisition, the entire process is program-tracked to complete the construction of the data receiving link and the command uplink link. Then, the shipborne station down-converts the data from the satellite to 1.2GHz, demodulates it through the data transmission baseband, and sends it to the data center for data processing. Finally, the shipborne station up-converts the control command data from the data center to 7.2GHz through the telemetry and control baseband, amplifies the signal through the power amplifier, and transmits it to remotely control the satellite.
[0017] In summary, the beneficial effects of this utility model are as follows: the shipborne station adopts an azimuth-elevation-cross triaxial antenna mount and a program tracking system, which can ensure that the antenna is effectively isolated from the ship's movement and that the antenna beam is always accurately pointed to the target satellite, providing a reliable data reception link for the channel equipment. At the same time, the antenna radome can form a closed space, isolating it from the outside, which can effectively change the operating environment of the antenna structure and electrical equipment, extend its service life, and ensure the effect of data reception.
