3 results about "Ground slope" patented technology

Slope (plural slopes) An area of ground that tends evenly upward or downward. The degree to which a surface tends upward or downward. (mathematics) The ratio of the vertical and horizontal distances between two points on a line; zero if the line is horizontal, undefined if it is vertical.

Mountain-based building node vertical component machine installation method

The application discloses a mountainous building node vertical component machine installation method, relates to the technical field of building node vertical component machine installation, and comprises the following steps: performing multi-source topographic survey on a mountainous construction area, obtaining actual three-dimensional coordinates, ground slope components and local elevations of installation points, and determining terrain deviation parameters in combination with design elevations in a building information model; calculating positioning correction amounts of vertical components under non-horizontal ground surfaces according to the terrain deviation parameters, wherein the correction amounts comprehensively consider slope nonlinearity influence and foundation elevation differences, and are used for adjusting support heights and spatial postures of installation equipment; after posture adjustment is completed, the vertical components are transported to above target nodes and primary positioning is realized, so that vertical positions of component bottoms and lower structure butt joint areas meet preset accuracy requirements; and the components are controlled to slowly descend, and three-dimensional force and torque information in a contact process is collected through force sensors on end effectors when the components contact the building nodes.

PendingEP4564119A4Mechanical engineeringGround slope
A ground slope detection method, device and computer-readable storage medium. The method includes: (S1) during landing of an aircraft, calculating a unique plane of at least three downward-looking distance detection points in a body coordinate system of the aircraft according to three-dimensional attitude data of the aircraft and distance data of at least three downward-looking rangefinders provided on the aircraft; (S2) calculating a rotation matrix of the body coordinate system to a geodetic coordinate system by the three-dimensional attitude data, and calculating a first unit normal vector of the unique plane in the geodetic coordinate system according to the rotation matrix; and (S3) calculating an included angle between a second unit normal vector of a geodetic horizontal plane in the geodetic coordinate system and the first unit normal vector, and generating a warning signal of excessive ground slope when the included angle is greater than or equal to a preset threshold. The method reduces the system hardware cost and maintenance and use difficulty of slope detection, providing effective protection for the safety of aircraft landing.
