Embodiment Construction

[0018] The present invention will be described in detail below in combination with specific embodiments.

[0019] In the method, the total station is controlled to collect data in a wireless or wired manner through a measuring handbook. All relevant calculations and analyzes can be processed directly on the hand book, and the processing results can be seen immediately after the measurement. No paper records are required on site, and a complete digital process is realized. After the measurement is completed, it is only necessary to copy the results to the computer without any post-processing analysis of the data. The system software is designed with the goal of maximizing the efficiency of field data collection, reducing the labor intensity of survey workers, and realizing integrated processing inside and outside the field. After the data collection of the measuring station is completed, you can check whether the deviations are over the limit. If the deviation of some GRP poin...

Abstract

The invention relates to a real-time data acquisition and data processing integrated field measuring method of a rail datum network. In the known rail datum network, a method of respective indoor processing and field processing is adopted, data acquisition software is adopted in operation to collect data in the field, the data is stored into a format required by indoor calculation in real time, the data is collected and led into indoor software to be processed and calculated, and the field observed value is checked indoors, therefore, rework is easily caused. The real-time data acquisition and data processing integrated field measuring method combines indoor data acquisition with field data processing of the rail standard network, ensures that completes the two procedures at the same time in the same place and rework can be carried out on unqualified stations in time in the data acquisition process, therefore, the effectiveness and the accuracy of field data acquisition are effectively ensured, and the influence on the progress of work caused by unqualified field calculation and field rework is avoided; and the data processing algorithm is accurate and reliable, the system has the functions of gross error detection and analysis, the unqualified data is automatically removed in the processing procedure, and the accuracy and the reliability of the result can be greatly improved.

Description

technical field [0001] The invention relates to a real-time integrated measurement method for data collection and data processing of a track reference network. Background technique [0002] In the CRTS II ballastless track system, track slab layout and precise grinding, construction section calculation, track reference network positioning measurement, slab fine-tuning data calculation, and track slab fine-tuning results evaluation are key measurement technologies to ensure the final track slab installation accuracy. Since the CRTS II slab system is a newly emerged ballastless track technology, the design and construction calculation of track slabs are completely dependent on foreign commercial software, such as the completed Beijing-Tianjin intercity and the under-constructed Beijing-Shanghai Expressway. The passenger trains are all calculated using the PVP layout software of the German Borg company. [0003] The well-known track reference network measurement adopts the mea...
