Embodiment approach

[0030] According to a kind of embodiment of the present invention, adopt dual-frequency correlation method (references: Sun Hongxing, Li Deren. Use dual-frequency correlation method single epoch to solve GPS whole week ambiguity value [J]. Surveying and Mapping Journal, 2003, 32 (3 ): 208-212.)) and direct calculation method (references: Wang Xinzhou, Hua Xianghong, Qiu Lei. A new method for solving the ambiguity of the whole circle in GPS deformation monitoring [J]. Journal of Wuhan University (Information Science Edition) , 2007, 32(1):24-26.) Rapid determination of single-epoch double-difference integer fuzzy parameters by combination of algorithms.

[0031] According to an embodiment of the present invention, the method for quickly determining single-epoch double-difference integer fuzzy parameters by combining the dual-frequency correlation method and the direct calculation method is as follows.

[0032] First, the navigation satellites of each observation epoch are scree...

Abstract

The invention discloses a three-dimensional dynamic detection and grading early warning device for the tower top position of a building tower crane, which is used for a building tower crane system. The building tower crane system comprises a tower body of the building tower crane, a GNSS detection station located at the top of the tower body and a GNSS reference station located on a construction site. The device comprises a three-dimensional dynamic detection and calculation unit for receiving satellite positioning data with high sampling rate from the GNSS reference station and the GNSS detection station and calculating position detection results of the north direction, the east direction and the zenith direction of the tower top, a detection parameter determination unit which is used fordetermining tower top three-dimensional dynamic detection parameters of the current detection epoch according to the position detection results in the north direction, the east direction and the zenith direction of the tower top, an early warning parameter determination unit which is used for determining early warning parameters of the current detection epoch according to the nominal detection precision of the GNSS detection station, and an early warning unit which is used for comparing the tower top three-dimensional dynamic detection parameters with the early warning parameters and determining to carry out early warning according to a comparison result.

Description

technical field [0001] The invention relates to the technical field of construction tower crane and its health monitoring and early warning. Background technique [0002] Construction tower cranes occasionally have accidents, and once an accident occurs, it will cause greater losses. As the height of the tower body increases, if the tower body has a large inclination, it may cause a major safety accident. Therefore, real-time and accurate detection of the tower tilt is of great significance to ensure the safe operation of the tower crane. Contents of the invention [0003] In view of the above circumstances, the present invention proposes to alleviate or eliminate one or more disadvantages in the prior art, and at least provide a beneficial option. [0004] According to one aspect of the present invention, a three-dimensional dynamic detection and classification early warning device for the position of the tower top of a construction tower crane is provided, which is use...
