Description
Art
The present invention relates to a kind of railway track measurement device, particularly relate to the device of a kind of real-time measurement railroad track absolute location and deviation.
Background technology
The long wave ride comfort of railroad track detect for circuit speed-raising and the traveling comfort taken all extremely important, the method for inspection of traditional physics versed sine cannot detect the long wave irregularity of circuit.At present, high speed railway track is measured and is turned to absolute measurement by relative measurement from last century the eighties, and the external common method adopted is the method establishment attachment point reference system by attachment rail R point, achieves the absolute measurement of track.
Along with in succession building up of China Express Railway and railway line for passenger traffic, all establish the precise control net based on CPIII frame of axis.At present, railway maintenance department generally adopts total powerstation to coordinate the check implement of prism absolute measurement to carry out routine testing, but measure efficiency only 300 meters/skylight point (4 hours), lack high efficiency check implement, seriously constrain the maintenance repair efficiency of railway line, high speed railway normal operation and maintenance are exerted a certain influence.
Summary of the invention
The present invention is to solve existing railroad track absolute location and the inefficient problem of separate-blas estimation, provides the device of a kind of real-time measurement railroad track absolute location and deviation.
The present invention is achieved by the following technical solutions: the device of a kind of real-time measurement railroad track absolute location and deviation, be comprise Laser emission and receiving system, outer corner measurement unit, Inertial Measurement Unit, measurement of dip angle unit, mileage measuring unit, prism, data processing unit, described Laser emission is connected with data processing unit respectively with receiving system, outer corner measurement unit, Inertial Measurement Unit, measurement of dip angle unit, mileage measuring unit.
Described Laser emission and receiving system, outer corner measurement unit, Inertial Measurement Unit, measurement of dip angle unit, mileage measuring unit, data processing unit are arranged on measurement mechanism respectively.
Described prism is be positioned on the fixed bearing of track both sides old friend's parameter.
Railroad track absolute location provided by the invention and deviation measurement device, bring up to 20 kilometers/skylight point (4 hours), substantially increase railway overhaul efficiency, for the safe operation of high speed railway provides safeguard by measurement efficiency.

Detailed description of the invention
As shown in Figure 1, Laser emission of the present invention is connected with data processing unit 7 respectively with receiving system 3, outer corner measurement unit 4, Inertial Measurement Unit 2, measurement of dip angle unit 5, mileage measuring unit 6.
As shown in Figure 2, Laser emission of the present invention and receiving system 3, outer corner measurement unit 4, Inertial Measurement Unit 2, measurement of dip angle unit 5, mileage measuring unit 6, data processing unit 7 are arranged on described measurement mechanism 1 respectively; Described prism 8,9 is fixed on the fixed bearing of track 10 both sides known coordinate.
As shown in Figure 3, Laser emission of the present invention and receiving system 3 are made up of laser analog signal receiver 11, laser 12, laser digital signal receiver 14.
Measurement mechanism provided by the invention is laid with on the track circuit of Controling network at the uniform velocity out of shape in both sides, the laser rays 13 that Laser emission and receiving system 3 utilize laser 12 to send scans the prism 8,9 on the fixed bearing of both sides, front, and receiver of the analog signal and digit signal receiver process the data returned in real time; When the inswept receptor center line of laser rays 13, outer corner measurement unit 4 to take measurement of an angle B in real time according to the signal I that laser digital receptor feeds back; Inertial Measurement Unit 2 measures carrier coordinate system cireular frequency Wx, Wy, Wz and the signal such as acceleration A x, Ay, Az in real time, data processing unit 7 filtering and Integral Processing obtain the spatial attitude of measurement mechanism, and attitude algorithm can obtain the information such as measurement mechanism position and speed; Again in conjunction with outer corner measurement value B, measurement of dip angle value A and mileage observed reading S, get final product the spatial relation of real-time computation and measurement device 1 and prism 8,9, and according to prism 8,9 coordinate and current line design information, calculate track 10 circuit absolute location and deviation.When measurement mechanism 1 fast close to by scan prism 8,9 time, Laser emission and receiving system 3 will automatically switch, real time scan next organize prism, complete continuous gauging.
