The invention discloses an intelligent control system for a portable satellite antenna and a method, wherein the method comprises the steps of initializing an antenna; controlling the antenna through an antenna main control module to search; reading satellite signal level data transmitted by a receiver module at a certain frequency; regulating the direction and the pitch angle of the antenna to the direction and the pitch angle corresponding to the maximum satellite signal level data; adopting a step tracking way to regulate the direction and the pitch angle of the antenna; controlling motorsto carry out regulatiion by a step in the current direction by the antenna main control module if the regulated level data of the current time is larger than the level data obtained after the last regulation; and controlling the motors to carry out regulation by a step in the opposite direction by the antenna main control module until the antenna receives the maximum signal level if the regulatedlevel data of the current time is less than the level data obtained after the last regulation. The invention can ensure that the efficiency and the accuracy of star pairing can be enhanced; the star pairing time is saved; and the star pairing operation is simplified.
Description
technical field [0001] The invention relates to the technical field of satellite antenna control, in particular to an intelligent control method for a portable satellite antenna. Background technique [0002] The satellite dish is responsible for reflecting the satellite signal into the feed and tuner at the focal point. The function of the satellite dish is to collect the weak signal transmitted by the satellite and remove the noise as much as possible. Most satellite dishes are parabolic, and some multi-focal antennas are a combination of spherical and parabolic. Existing portable satellite antennas are generally manually controlled. The operator manually rotates the azimuth, elevation angle, and polarization of the antenna, and observes the satellite signal with a meter until the satellite signal is the largest, and then aligns with the satellite. This artificial star alignment method has the following problems: first, the operation of star alignment is complicated, and...
