High-precision real-time tracking shipborne antenna attitude control system

Abstract

The invention provides a high-precision real-time tracking shipborne antenna attitude control system, mainly composed of an outer layer protective shell, a load bearing rotation module and a trackingadjustment module, wherein the load bearing rotation module comprises a stepping motor a, a stepping motor b, a rotating steel frame a, rotating steel frame b, a supporting steel frame 3, a rotating bearing and a rotating shaft; and the tracking adjustment module comprises a stepping motor a, a stepping motor b, an electronic compass, a microprocessor, a three-axis acceleration sensor and a three-axis gyroscope, the data collected by the electronic compass, the three-axis acceleration sensor and the three-axis gyroscope are transmitted to the microprocessor in one direction, and the microprocessor controls the rotation of the stepping motor a and the stepping motor b through processing so as to actively adjust the attitude. According to the high-precision real-time tracking shipborne antenna attitude control system provided by the invention, the deviation position is obtained more accurately by using the electronic compass, the three-axis acceleration sensor and the three-axis gyroscope; and the hysteresis quality of the attitude adjustment process is eliminated by using an active predictive tracking processing method, and high-precision direct communication between a ship and theground is achieved.

Description

technical field [0001] The invention belongs to the technical field of attitude adjustment systems, in particular to an attitude adjustment system capable of automatically tracking a transmitting source or a receiving source for ship-ground communication or ship-ship communication. Background technique [0002] Different from the general relatively fixed ground antennas, ship-borne antennas will undergo various uncertain movements in the actual working environment due to the ship's course motion, hull fluctuations and strong winds, which will cause the ship-borne antenna to deviate from the optimal emission or reception of electromagnetic waves. Therefore, the shipboard antenna needs to adjust the pitch and azimuth rotation to aim at the target source. At present, the main attitude adjustment system in the patent is the attitude adjustment system for tracking satellites, which lacks the invention and design of the ship-borne attitude adjustment system for ship-ship communica...

Problems solved by technology

At present, the main attitude adjustment system in the patent is the attitude adjustment system for tracking satellites, which lacks the invention and design of the ship-borne attitude adjustment system for ship-ship communication and ship-ground communication, which cannot meet the requirements of direct communication between the ship and the ground without satellites. The needs of direct communication, such as: land connection on board live broadcast
