When measuring track circuit coordinate, on track circuit 100 erection of each prism (surveyed using prism tooling with leveling
Must leveling before amount orbit coordinate) or so half a minute need to be expended, the erection of six prisms then needs three minutes.Prism places personnel
It need to back and forth run in 300 meters and set up and collect prism, this process expends a large amount of personnel's muscle power and time.Moreover, measuring
Precision is highly prone to the influence of placement personnel, and precision influence generally reaches as many as three millimeters.Its specific measures is illustrated such as 2 institute of attached drawing
Show, it is illustrated that in, 10 be 1 point of CP, and 20 be 1 point of CP, and 30 be Setting Station of Total Station Instrument point, and 40 be line marker point.Track linear measurement
It is measured including spud pile 5 and track plan, vertical position relationship, track circuit linear measurement between spud pile 5.Circuit linear measurement
It is measured using rail inspection instrument 2.It measures and uses step-by-step system, positioning vehicle 7 is stationary when measurement, measures vehicle 6 along track circuit
100 move to positioning vehicle 7, and positioning vehicle 7 is moved to next section (such as L1 to L2 institutes in attached drawing 3 again after having measured a section
Show), start next section of measurement, as shown in Fig. 3.
As shown in Fig. 4, in a measuring section EF, when track record vehicle is transported from the corresponding mark point E of a fixed point
Row is at the corresponding mark point F of next fixed point.Satellite car rests in the G points at about 10 meters after F points.Optical camera system
Primary optical axis 9 is intersected in H points with track circuit 100 (H points may be overlapped with E points).It can obtain target in real time in measurement process
The horizontal displacement of vehicle is vector distance of the every bit on track circuit 100 between EF to string GH.According to measurement request, need in target
Vehicle reach F points after by the measurement initial data of laser system be converted into the every bit on track circuit 100 between EF to string EF arrow
Away from PR, i.e. rail is to value.
Currently, railway engineering networking measures the coordinate for measuring CP 1: 20 using total powerstation 2, railway line is additionally measured
The coordinate on road 100, measuring circuit coordinate levelling device, (route survey coordinate levelling device is one that circuit coordinate measures tooling
Point, route survey tooling is divided into levelling device and prism) leveling takes time and effort.One route survey prism of setting at least needs not a half
The time of minute, and two people are specially needed when measurement the prism on circuit is arranged, total powerstation operating personnel measure railway line
Coordinate on road 100 often stands and five minutes or so need to be spent to measure circuit coordinate.And made due to circuit coordinate measuring device
With the measurement error that coordinate can be made to generate 2mm or so (artificial error is 2mm in general measuring).Therefore, it is badly in need of research and development
A kind of effective track circuit measuring system carrys out the measurement of alternate track circuit coordinate, to be greatly decreased manpower and materials and
Time cost, while significantly improving measurement homework precision.
