Antenna controller for advanced broadcasting system-satellite (ABS-S) satellite signal mobile-satellite

Abstract

The invention provides an antenna controller for an advanced broadcasting system-satellite (ABS-S) satellite signal mobile-satellite, and belongs to the technical field of antenna control of the mobile-satellite. The antenna controller solves the problems that the antenna controller cannot accurately identify an ABS-S standard satellite, is inconvenient for system upgrading, and complex in control and operation and the like in the prior art. The antenna controller is independent of a mobile-satellite antenna, is connected with the mobile-satellite antenna and a satellite receiver respectively, and comprises a main control circuit, a power supply management circuit, and a liquid crystal display (LCD) liquid crystal screen and a key circuit which are connected with the main control circuit respectively, wherein the power supply management circuit is connected with the main control circuit, supplies power to the main control circuit, and can convert input direct current voltage into required voltage; and the main control circuit can distinguish the voltage of the satellite receiver, and simultaneously the main control circuit normally communicates with the mobile satellite antenna and controls the mobile satellite antenna until a target satellite is locked. The antenna controller can accurately identify the ABS-S standard satellite, and is convenient for system upgrading and simple and convenient for control and operation.

Description

technical field [0001] The invention belongs to the technical field of mobile satellite antenna control, and relates to a mobile satellite antenna controller for ABS-S satellite signals. Background technique [0002] The Zhongxing-9 satellite adopts the ABS-S standard independently developed by my country, and is currently the only live TV satellite using this standard over the equator. In the field of mobile satellite antennas, if the antenna is to automatically track satellites, it must first accurately identify the target satellite. At present, the mature automatic satellite finding technology in the world mainly relies on the DVB demodulation method to identify satellites, and cannot demodulate the satellite signals of the ABS-S standard, and the satellite identification technology using the ABS-S standard is not yet mature. [0003] At present, the mobile satellite antennas on the market are almost not equipped with antenna controllers. All the controls of the antenna ...

AI Technical Summary

Problems solved by technology

This main control system is reasonable in design and simple in structure, but the system still has the following deficiencies: 1. The mobile satellite antenna relies on tracking a specific transponder frequency to keep the satellite locked. If the transponder parameters of the satellite change, or other satellites are turned on If you use a transponder with the same polarization and frequency, the antenna will not be able to lock on to the satellite or lock on to the wrong satellite

At this time, it is necessary to modify the internal control parameters of the antenna. This system has an indoor subsystem, but since the indoor subsystem has no external upgrade interface, the shell of the indoor subsystem can only be disassembled, and the system can be upgraded by professionals using a computer. , the operation is troublesome, time-consuming and labor-intensive; 2. Although this ship-borne mobile satellite antenna control system overcomes the problems of unstable tracking performance and easy loss of signals on ships, the accuracy of satellite identification of the ABS-S standard is not enough; 3. This system The signal strength of the antenna is not displayed, which makes it difficult to troubleshoot the antenna and reduces the applicability
