Abstract

The invention discloses a ballastless track slab temperature high speed dynamic measuring system. The ballastless track slab temperature high speed dynamic measuring system is used for measuring the temperature of a ballastless track slab; the ballastless track slab temperature high speed dynamic measuring system is mounted at the bottom of a train; and the ballastless track slab temperature highspeed dynamic measuring system comprises an optical information collection module, a photoelectric temperature measuring module and a temperature control box, wherein the optical information collection module is used for collecting spectral information of a sampling point of the ballastless track slab and transmitting the spectral information to the photoelectric temperature measuring module, thephotoelectric temperature measuring module is used for converting the spectral information into an electric signal and calculating the temperature of the sampling point according to the electric signal, and the temperature control box is used for adjusting the temperature of a working environment of the photoelectric temperature measuring module. According to the ballastless track slab temperaturehigh speed dynamic measuring system, with the train as a carrier, the temperature of the ballastless track slab of a railway line can be measured at a high speed in real time, and spatial sampling iscarried out at an equal interval of 250 mm to measure the temperature of the ballastless track slab under a double-direction (a forward direction and a reverse direction) running condition with trainspeed of 400 km / h in a high temperature or cold environment (a temperature range from a low temperature of -40 degrees to high temperature of 60 degrees).

Description

technical field [0001] The invention relates to the field of temperature detection of ballastless track slabs, in particular to a high-speed dynamic temperature measurement system for ballastless track slabs. Background technique [0002] The stability and smoothness of the high-speed railway track structure directly affect the operation safety of the high-speed railway. Ballastless track slab, as the main track structure of high-speed railway, is exposed to the atmosphere for a long time and is affected by atmospheric temperature, solar radiation, precipitation and other environmental factors. Under the influence of external factors such as temperature and solar radiation, the track slab will Uneven temperature distribution occurs, resulting in large temperature stress, which in turn causes concrete cracking and structural deformation and other diseases, seriously affects the geometric smoothness of the track, and even threatens the safety of the train. Accurately and quic...
