SY97594轨检车是我国研制的第一辆新型轨道检查车,车上安装了美国ENSCO公司的轨道几何状态测量系统和数据处理系统以及我国自行研制的检测装置。利用从陀螺、加速度计、倾斜仪、位移计等传感器输出的模拟信号,合成为轨道几何状态信号,在波形记录仪上绘出轨道实际状态,并且通过A/D转换装置转换成数字信号,记录在磁带机上。控制台显示出里程位置,运行速度和各种操作信息。数据处理系统实时打印出超限报告表、公里小结表、区段总结表、曲线报告表。该车的特点是:采用先进的检测技术和原理、测量精度高、系统稳定可靠。 本文系统地介绍了轨道几何测量系统的测量原理、组成和功能。主要包括:轨距、轨向、高低、水平、三角坑、曲率等轨道几何参数的测量概念和方法;实时采集和处理数据的方法;实时测量结果的输出和分析。
The SY97594 track inspection car is the first new track inspection car developed in China. The track geometry measuring system and data processing system installed by the American company ENSCO are installed in the car and the testing device developed by our country. Using analog signals output from gyroscopes, accelerometers, inclinometers, displacement meters and other sensors, the signal is synthesized into a track geometry, and the actual state of the track is plotted on the waveform recorder and converted into digital signals by A / D conversion means to record On the tape drive. The console shows the location of miles, speed of operation, and various operational information. Data processing system real-time print out the limit report form, km summary table, section summary table, curve report table. The car is characterized by: the use of advanced detection techniques and principles, high accuracy, the system is stable and reliable. This paper systematically introduces the measurement principle, composition and function of orbital geometry measurement system. It mainly includes the measurement concepts and methods of orbit geometric parameters such as gauge, orbit, level, level, triangular pits and curvature; the method of real-time data collection and processing; the output and analysis of real-time measurement results.
