Track detection device based on inertial measurement

Abstract

The invention aims at providing a track detection device based on inertial measurement. The track detection device based on inertial measurement comprises an inertial measurement module; the inertialmeasurement module comprises a laser scanner, an adapter plate, a detection beam, laser range finders, connector interfaces, line boxes and an inertial navigation system, wherein the adapter plate isarranged on the detection beam; the laser scanner is arranged on the adapter plate; the laser range finders are arranged at the two ends of the detection beam; the inertial navigation system is arranged in the middle of the detection beam; the line boxes are arranged in the positions, on the detection beam, on the two sides of the inertial navigation system; and the connector interfaces are formedin the positions, on the detection beam, on the external sides of the line boxes. The track detection device based on inertial measurement has the advantages that the track detection device based oninertial measurement can be mounted on a running train and can also be mounted on a driving trolley to independently operate; and as a vehicle-mounted dynamic detection mode of the track detection device based on inertial measurement has small influences on normal operation, possesses high efficiency and high speed and really reflects the state of infrastructures under a train running condition, the vehicle-mounted dynamic detection mode of the track detection device based on inertial measurement can be used as one of main detection means of safety states of railway and urban rail transit infrastructures.

Description

technical field [0001] The invention belongs to a track detection device, in particular to a track detection device based on inertial measurement. Background technique [0002] In recent years, my country's railway and highway transportation have developed rapidly, especially the construction of high-speed railways. The main channel of the "eight vertical and eight horizontal" high-speed railway network. With the rapid development of China's high-speed railway and urban rail transit construction, the research on precise measurement technology of track lines with track precision detection technology as the core has gradually become an important means to ensure the comfort and safety of train driving. Many countries have invested a lot of manpower and material resources to develop and update various testing equipment to meet the requirements of today's high-speed and heavy-duty railways. [0003] Track inspection technology has become an important bottleneck restricting the c...

Problems solved by technology

Large-scale rail inspection vehicles have fast detection speed and high operating efficiency, but because they are expensive and not suitable for construction measurement of lines under construction, they are generally used for routine periodic maintenance of existing high-speed lines and cannot be widely used
