Development Of Intelligent Gauge Scale

Intelligent gauge scale is used to measure the railway line between the two stock rails horizontal distance, as well as ultra-dedicated measuring instruments, etc.. As the train’s speed and high-speed train line opened, the quality of the railway line equipment, higher standards and requirements, especially for track geometry measurement of the main measuring gauge ruler set higher standards to meet the high-speed train line needs. However, the current measurement tools used by both foot gauge railway scale show that in everyday use due to subjective judgments by its structure and human factors such as the impact of numerical precision measurement of low, big error, operation inconvenience shortcomings, has been unable to meet the Current high-speed rail development. In response, the Ministry of Railways in2008revised the "《TB/T1924-2008standard gauge railway gauge-foot》" and "《The People’s Republic of China national metrological verification JJG219-2008-foot rail gauge》," the provisions of test procedures. Right foot gauge production and performance of proposed new requirements. Therefore, the development of smart-foot gauge railway to the development of China’s great significance.This paper discusses the working principle of intelligent gauge scale and method, In this paper, an emphasis on ultra--high gauge testing system hardware and software design a comprehensive exposition. On the hardware design of the detection system mainly discusses the principle and selection of peripheral devices, the hardware division of functional modules on the system hardware ant i-jamming techniques are described to improve the system anti-jamming capability. In software design, intelligent gauge scale detailed design of testing and operating procedures. After the temperature test, temperature compensation done on the system, greatly reduces the system affected by temperature. Complete, the system has done a lot of performance testing were obtained by experiments the system precision and error analysis is given.
