Abstract


At present , China's railway construction career entered a new phase of large-scale high-speed railway construction , the precision engineering measurement technique is one of the most important technical support . In this paper, the non-ballasted track CP Ⅲ control network type and its methods of observation , the accuracy of the CP III network estimates its field observation measuring instruments accuracy specifications , CP III network adjustment calculation method and its corresponding data processing software developed for the the main object of study , the CP Ⅲ control network data processing involves the measurement theory , functional design and development on the the CP Ⅲ control of data processing software . The main research contents include: First , for CP III control grid , improved joint measurement methods outside the industry ; \accuracy , the accuracy of the relative position between the CP Ⅲ control network point precision and point the prior estimate : CP Ⅲ Network three adjustment calculation method , the mathematical model and its accuracy evaluation formula is derived for the subsequent software programming provides a theoretical basis : the second , for the the CP Ⅲ control of data processing software should have the function to determine the principles and objectives of the software development , the design of the software structure and data flow , the software part of the functional modules development, and software integration technology to integrate the various functional modules to form a complete set of the CP Ⅲ control network data processing software ; third, for CP III control the quality and accuracy of the measured data , using the developed software , how to locate and removed observations contain large errors in the control network . Finally , a CP Ⅲ network construction and retest results contrast analysis and discussion of the problems that may arise the CP Ⅲ control network construction and retest process , pointed out the problems that need attention in the the CP III network observation and treatment process .
