Embodiment approach
[0060] In this embodiment, the above-mentioned first position parameter acquisition unit 1 includes: a magnetoresistive sensor 11, which is used to measure the induction intensity of the earth's magnetic field; an acceleration sensor 12, which is used to measure the acceleration of gravity; and a first calculation unit 13, which is used to measure the The elevation angle and azimuth angle of the location of the LNB are obtained by calculating the induction intensity of the geomagnetic field and the acceleration of gravity. Since the method of measuring the elevation angle and azimuth angle of the location through the induction intensity of the geomagnetic field and the acceleration of gravity at the location belongs to the disclosed technology in the technical field, it will not be described in this specification.
[0061] In this embodiment, the above-mentioned second position parameter acquisition unit 2 includes: a receiving unit 21, configured to receive the longitude of th...

The invention discloses a positioning method for an LNB (low noise block downconverter). The method comprises the following steps of: obtaining the position parameter of the LNB position and the position parameter of the LNB target position to be aligned respectively; and adjusting the LNB to the LNB target position according to the deviation between the position parameter of the LNB position and the position parameter of the LNB target position so that the LNB position is consistent with the LNB target position. The invention also discloses a positioning device for the LNB. Through the invention, the technical problems of complicated mounting process and low assembly precision of the prior art in which the LNB is mounted based on the experience of the mounting personnel are solved, and the technical effects of reducing the LNB mounting difficulty, enabling mounting to be faster and more convenient and improving the assembly precision are realized.
Description
technical field [0001] The invention relates to the technical field of satellite TV antennas, in particular to a low-noise down-converter positioning method and device. Background technique [0002] At present, the coverage of satellite TV is getting wider and wider, and our country has also launched satellite projects such as direct broadcast satellites accordingly. When watching satellite TV, you must first set up an LNB (Low Noise Block, low-noise downconverter). Signal. Because the satellite signal is quite weak before reaching the antenna, and the higher the frequency of coaxial cable transmission, the greater the signal loss, so LNB is needed to improve the satellite signal. [0003] The existing method of erecting LNB is to rely on professional installers to manually install LNB with experience and judge the approximate orientation. This method requires installers to roughly judge the installation angle of LNB according to the local latitude and longitude, and then ...
