Abstract

The invention discloses a hierarchical cache system for a ship navigation satellite communication antenna, comprising a control circuit board, an angle adjustment system, an azimuth adjustment system,an antenna turntable, a ring focus antenna, a tracking receiver, a collapsed source disk, a GPS positioning device, an angle sensor, a cache system and a photovoltaic charging vehicle; the control circuit board comprises a microprocessor; the cache system comprises a plurality of memory chips; the photovoltaic charging vehicle is used for providing electrical energy; the cache system is divided into a plurality of memory areas, and the microprocessor communicates with the memory areas and controls whether the memory areas run and buffer; the ring focus antenna is fixed on the antenna turntable; the collapsed source disk and the ring focus antenna are connected; the microprocessor adjusts the position of the antenna turntable according to the GPS positioning device and the detected signalangle sensor; and the microprocessor controls the running state of the memory areas according to the hierarchy of an instruction. By properly arranging the memory chips to run the cache, the problem of slow running speed is solved, and handling of the instruction when the ship communication antenna is in an emergency circumstance is met.

Description

technical field [0001] The invention relates to the field of ships, in particular to a hierarchical cache system of a ship navigation satellite communication antenna and a method for using the same. Background technique [0002] Currently, satellite antennas receive weak satellite signals and reflect the satellite signals to low-noise down-amplifiers in the dish. The low-noise down-frequency amplifier amplifies the concentrated signal to hundreds of thousands of times, and then uses the oscillator circuit to convert the high-frequency satellite signal to an intermediate frequency. The IF signal is a modulated signal, and after being demodulated by the set-top box, it can be converted into an audio-visual signal, which can then be input to the TV. [0003] However, the existing shipborne satellite antennas have the following drawbacks: [0004] In the prior art, since the satellite antenna of the mobile carrier is in use on the ship, the memory in the ship antenna needs to ...
