Abstract

The invention discloses a seamless railway track absolute position and displacement wireless measurement device and method. The device comprises a wireless sensor terminal which is arranged at a seamless steel rail weld and used for obtaining the seamless railway track absolute position and displacement of a seamless railway track creeping in the train operation direction, a mobile hand-held terminal prompting system measurement results and system working conditions for patrol personnel and a PC upper computer arranged in a monitoring work station; the wireless sensor terminal keeps a detection state and communicates with the mobile hand-held terminal through a random channel according to a random channel keep-alive mechanism; when the patrol personnel communicate through a serial port or a USB, data collected by the mobile hand-held terminal is uploaded to the PC upper computer. Accordingly, measurement of seamless railway track absolute position and track creep displacement in the train operation direction, data collection and statistics, overrun warning and other functions are achieved, and the device and method have the advantages of being high in observation accuracy, high in efficiency, small in size, capable of achieving automatic data statistics and analysis and the like.

Description

technical field [0001] The invention relates to the technical field of track detection, in particular to a wireless measuring device and method for absolute position and displacement of a seamless railway track. Background technique [0002] According to data released by relevant departments, by 2020, my country's high-speed railway operating mileage will exceed 16,000 kilometers, and the operating speed of high-speed railways will also increase steadily. With the vigorous development of my country's high-speed rail, at the technical level, in addition to continuous breakthroughs in traction drive technology, braking technology, and operation control technology, the comprehensive application of seamless rails has also played an important role in the development of high-speed rail. The so-called seamless rail is to weld the rail of standard length into a rail with a length of several hundred to several thousand meters through certain technical means. Play an important role. ...
