Embodiment

[0045] in summary:

[0046] The present invention includes two space objects A and B, using instruments: a compass and an inclinometer, and also includes related data such as azimuth and pitch angle after measurement by GPS.

[0047] Its working process is:

[0048] The horizontal plane passing through a fixed point in space is unique, and there are countless direction lines passing through a fixed point in this horizontal plane, but there is one and only one direction line with a magnetic north angle γ (or 180+γ), and at this time the direction line is the same as AB The connection between objects forms the only plane in space: plane AB, which is perpendicular to the horizontal plane; using the north arrow in the relevant horizontal plane, the direction line of object A or B can be adjusted to plane AB. Use the inclinometer to adjust the direction line of object A or B up and down in plane AB to complete the alignment of object A or B.

Abstract

The invention discloses a compass and gradient based point-to-point alignment method. According to the compass and gradient based point-to-point alignment method, two objects A and B in three-dimensional space are performed on point-to-point alignment; required main tools for aligning the two objects comprise a gradienter and a compass; other auxiliary tools comprise a position finder (such as a GPS (Global Positioning System) or a compass, a GPS position finder is taken for example in the invention) and a height gauge; azimuthal angles of the two points are confirmed directly by utilizing existing positions of the two points, then pitch angles are formed through relative height, and the compass is used for confirming the azimuthal angles and the gradienter is used for confirming the pitch angles. The compass and gradient based point-to-point alignment method has the advantages of solving the antenna alignment problem in microwave communication through the gradienter and the compass, solving the problems that, during antenna alignment process, the distance is far and visibility is not available, the antenna requires repeat tower climbing to be calibrated, the device requires to be operated with electricity during antenna calibration and the like, saving engineering construction time and costs and reducing construction dangerous levels.

Description

technical field [0001] The invention relates to a point-to-point alignment method of two objects in three-dimensional space, in particular to a method for alignment by using a compass and an inclinometer (level). Background technique [0002] At present, during the installation of microwave communication equipment, it takes a long time and is difficult to align the antenna. It is even more difficult to align antennas with non-visible distances and height differences. Traditional microwave antenna alignment methods mainly focus on measuring the received signal field strength of the microwave antenna. This method cannot completely align the antenna, but can only be infinitely close to the alignment state. The traditional method needs to measure the uplink receiving level RSSI of the ODU, and it must be used when the microwave antenna signal is turned on. The microwave signal radiation affects the health of the construction workers. Using this method takes a long time and requi...
