Abstract

The invention provides a detection method, device and system for horizontal swing displacement of a cable. A first distance between a first position and the middle point of the cable is collected, and the included angle between a first plane and the horizontal ground is collected; and according to the first distance, a second distance and the included angle, the horizontal swing displacement of the cable is determined, and the second distance represents the linear distance between the first position and a second position. The horizontal swing displacement of the cable can be calculated directly based on high-reliability high-instantaneity wireless range-finding and angle measuring results, integration operation is not needed, interference of baseline drift and low-frequency noises caused by integrates is not generated, the precision of a detection result of the horizontal swing displacement of the cable is improved, the detection result is highly real-time, the detection result is not influenced by ultra low frequency, and the problem that a detection result of a detection scheme in the prior art is low in precision and instantaneity is solved.

Description

【Technical field】 [0001] The solution relates to the communication field, in particular to a method, device and system for detecting the horizontal galloping displacement of a cable. 【Background technique】 [0002] During the construction and operation of large-scale suspension bridges, the long-span main steel cables will generate horizontal galloping displacement under natural loads such as wind and rain, vehicle loads, and structure installation. This horizontal galloping is similar to that of a long bridge The dancing of the suspension rope has certain hazards to the safety of construction personnel and the safety of fixed structural parts, and serious accidents will occur. In this paper, this type of horizontal galloping displacement is collectively referred to as cable horizontal galloping displacement. [0003] In order to ensure the safety of production or construction in the project, and to monitor the construction progress and construction quality, it is necessary...
