Description

Intelligent track panel fine adjustment measurement system for track engineering Technical Field The invention relates to the technical field of track measurement, in particular to an intelligent track panel fine adjustment measurement system for track engineering. Background The ballastless track has the advantages of stable structure, long service life, small maintenance workload and the like, and is widely applied to railway construction, particularly high-speed railway and urban rail transit. The ballastless track construction has extremely high accuracy requirements on the track panel position, and the accurate determination of the track panel beam position is one of key links for ensuring the track quality. The rail inspection trolley is an important tool for measuring the geometric state of a rail, the prism coordinates of the rail inspection trolley are measured through a total station, and the absolute geometric parameters of each measuring point on the rail are determined by combining other sensor data. However, the measuring process is extremely easy to be interfered by two factors, namely, microscopic non-uniformity of the surface state of the track, such as local rust, greasy dirt or concrete splashed objects, can cause a jump signal to be generated by a sensor carried by the trolley, and asymmetric abrasion of a travelling mechanism of the measuring trolley, such as small difference of left and right wheel diameters, can cause the trolley to generate inherent travelling yaw. These disturbances can directly contaminate the raw measurement data, resulting in misalignment of the adjustment calculated based on this data. If the construction is performed in this way, the adjustment may be insufficient or excessive, and even new irregularities may be introduced. Therefore, an intelligent track panel fine adjustment measurement system is needed in the current track engineering field, interference from an external factor of a track and an internal factor of a trolley can be sensed and effectively distinguished in real time in a high-precision automatic measurement process, and effective compensation or inhibition strategies are automatically adopted for different types of interference, so that the reality and reliability of measured data are ensured.
