Abstract


At present, the domestic rail operators greatly enhance the speed, the speed of passenger trains in China has entered the high-speed railway areas. The domestic rail inspection technology continues to improve, widely used in railway works departments, and to obtain significant results. But as a system of railway works, the work district maintenance department is still lagging means of detection, and the accuracy and reliability of the detection is difficult to meet the needs of the speed. There are still some problems in data recording and management of the track inspection. According to these questions, the thesis has completed the following work:(a) Analyze the strengths and weaknesses of the existing rail inspection technology and equipment, and the introduction of measurement uncertainty static track geometry parameter measurement equipment to be assessed. The measured results were compared and track static state management values, to provide guidance to the scientific and rational use of various types of testing equipment for orbital geometry control and innovation track inspection equipment.(b) Analyze the current situation and the main problems of the work area existing track geometry state detection system and propose solutions by developing the timely development and orbit control information system. At the same time, the needs and structural of two software part of the system are analyzed and the framework of them is proposed.(c) Analyze existing testing equipment of the work area, as well as its measurement uncertainty. And make a reasonable position to the new track inspection equipment.(d) Complete the structure design of the new rail tester and the sensor selection according to the principle and the measurement accuracy requirements. At the same time, the design of the under mechanical and electrical circuit is completed. By increasing the GPRS communications, GPS positioning module and LCD touch screen control unit to achieve a new track inspection instrument required.
