Embodiment Construction

[0049] The present invention will be described in detail below in combination with specific embodiments.

[0050] The overall adjustment method of track measurement data based on the track geometric state measuring instrument of the present invention is to carry out the overall adjustment processing of the observation data of the total station free station and the track geometric state measuring instrument prism, and the specific implementation method comprises the following steps:

[0051] Step 1: Check the orbit measurement observation data according to the observation technical requirements to ensure the quality of data observation.

[0052] Step 2: After the observation data is checked and passed, an adjustment file is generated.

[0053] Step 3: Use the known coordinates of the orbit control points and the observation values ​​of the total station to set up stations freely, and calculate the coordinates of each station in turn.

[0054] Step 4: Check the accuracy of the ...

Abstract

The invention relates to a track measurement data integral adjustment method based on a track geometrical state measuring instrument. According to the method, overall adjustment processing is carriedout on observation data of a total station free station and a track geometrical state measuring instrument prism; the problem that corners or abrupt changes are formed between adjacent observation stations due to independent adjustment processing of track measurement data according to an existing single observation station is solved, the influence of free station setting errors on track substationmeasurement is weakened, the relative precision between the adjacent observation stations is improved, and accurate measurement of the geometric state of the track is achieved.

Description

technical field [0001] The invention belongs to the technical field of track measurement, and in particular relates to an overall adjustment method of track measurement data based on a track geometric state measuring instrument. Background technique [0002] The accurate geometric dimensions of the track are the basic conditions to ensure the safe operation of the train. Theoretical research and practical analysis show that high-speed driving can only be realized on a highly smooth track. The key to the establishment and maintenance of high track ride comfort lies in the efficient and accurate measurement of track geometry. [0003] At present, the geometric state measurement of the track is usually carried out by the free station setting method of the total station and the geometric state measuring instrument of the track. The method is to erect the total station near the center line of the track, use the track control network that has been deployed along the line to freel...
