Track parameter dynamic test car based on combination of inertial sensor and navigational satellite

Abstract

The invention discloses a track parameter dynamic test car based on a combination of an inertial sensor and a navigational satellite. The track parameter dynamic test car based on the combination of the inertial sensor and the navigational satellite comprises a car body assembly, an inertial sensor assembly, a navigational satellite mobile station assembly, a navigational satellite base station assembly, a track distance measuring assembly, a speedometer assembly and a track test car control computer assembly. The track parameter dynamic test car based on the combination of the inertial sensor and the navigational satellite can automatically complete dynamic detection of nine track parameters such as height, track direction, distortion, level and superelevation, twist warps, plane degree, track distance, turn radius and mileage and the like after running on a track to be tested, achieves no-contact test, and achieves the highest test speed which is 60Kg / h. The track parameter dynamic test car based on the combination of the inertial sensor and the navigational satellite has the advantages of high and steady measurement accuracy, simple structure and easy operation, and is beneficial to generalize and use.

Description

technical field [0001] The invention relates to an orbit parameter detection device and a method thereof, in particular to a dynamic detection trolley for orbit parameters based on the combination of an inertial sensor and a navigation satellite. Background technique [0002] At present, the rail transit system generally adopts the total station detection system based on the optical measurement principle, or the single track geometric parameter detection device based on the physical, mechanical, photoelectric and other measurement principles in the process of track construction acceptance and routine maintenance. For track geometric parameters, these detection methods are also integrated on a portable track inspection vehicle, and the detection of complex track geometric parameters is realized by manual point-by-point movement and point-by-point measurement. These detection methods are low in automation, time-consuming, labor-intensive, easily affected by people and the envi...

Problems solved by technology

However, large-scale track inspection vehicles are expensive to build, and the vehicle body is too large to be carried. It will be greatly restricted in the acceptance of track construction and routine maintenance and repair.
