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 classification early warning device for the top position of a construction tower crane, which is used in a construction tower crane system. The construction tower crane system includes a tower body of a construction tower crane and a GNSS detection station located at the top of the tower body 1. The GNSS reference station located at the construction site, the device includes: a three-dimensional dynamic detection calculation unit, which receives high-sampling satellite positioning data from the GNSS reference station and the GNSS detection station, and calculates the north direction, east direction and sky direction of the tower top. The top position detection result; the detection parameter determination unit, from the north, east and zenith position detection results of the tower top, determines the three-dimensional dynamic detection parameters of the tower top in the current detection epoch; the early warning parameter determination unit, based on GNSS detection The nominal detection accuracy of the station determines the early warning parameters of the current detection epoch; the early warning unit compares the three-dimensional dynamic detection parameters at the top of the tower with the early warning parameters and determines the early warning according to the 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...
