High-precision harbor district storage yard track detection method based on total station

Abstract

The invention discloses a high-precision harbor district storage yard track detection method based on a total station, which comprises the following steps: taking two adjacent rails between adjacent tracks as a detection unit, and directly measuring absolute plane positions and elevations of the two adjacent rails in the detection unit by adopting the total station; obtaining absolute plane positions and elevations of the two rails of one track, and determining the deformation of each point of each rail according to the absolute plane positions and the elevations. According to the scheme provided by the invention, the absolute plane position and elevation are obtained through direct observation of the total station, so that the displacement and settlement conditions are accurately judged, displacement observation is completed with relatively small workload, the stacking of containers in a storage yard is not influenced, and the accuracy and efficiency of container area track detection can be improved.

Description

technical field [0001] The invention relates to the track detection technology, in particular to the track detection technology of the storage yard in the port area. Background technique [0002] A large number of track-based hoisting equipment - track cranes will be used in the process of container transfer in large port areas. The smoothness of the track involves safe production and work efficiency, and certain smoothness conditions must be guaranteed. [0003] For example, the Phase IV automation terminal of Yangshan Port Area in Shanghai, China is located on the westernmost side of the Yangshan Deepwater Port Area, and is currently the largest container automation terminal in the world. The storage yard track to be tested is located in the automated box area, arranged in sequence along Weisan Road from east to west, with a total of 61 locations. A single track is about 200 meters to 440 meters long. It is maintained once a year for track adjustment and measurement. The ...

Problems solved by technology

[0010] Disadvantages: First, there are many measurement sites, the amount of work is large, and the accuracy is easily affected by the proficiency of the operation; second, the plane displacement observation with the point phase separation

[0014] Disadvantages: Using steel ruler to measure the distance can only reflect the change of track width and determine the relative position of the corresponding points on both sides of the track, but cannot measure the distance of one side track The plane displacement cannot be compared with the design position, and the specific displacement situation is analyzed

In addition, the use of steel rulers or other direct ranging equipment requires visibility conditions, which requires the container yard to be cleaned up during the monitoring and maintenance process, which requires a lot of work and is also difficult. Adverse effects on the operation of the port area
