Provided is a device for measuring railway steel rail creeping displacement and vertical displacement, comprising pattern sheets, a foundation pile, a camera, and a server. The foundation pile is disposed on a side of a steel rail. The camera is disposed on the foundation pile and is right against the steel rail. An output interface of the camera is provided with a processor. The pattern sheets are disposed on a side surface of the steel rail, facing the camera, and the pattern sheets are in view-angle scope of the camera. The pattern sheets are provided with background patterns and foreground color patterns so that the processor is convenient to recognize images acquired by the camera. The processor is connected with the server through a wireless transmission module. The device is simple in structure, high in reliability, and is accurate, and early-stage construction is not needed, and skylight time is not taken up.
Description
Technical field
The utility model relates to railway precision measurement field, particularly a kind of creep device of displacement and vertical deviation of railway track of measuring.
Background technology
The most important condition that guarantees bullet train operation security and comfortableness is the high ride of track, and the high ride of track depends on the geometry state status of rail, therefore, extremely important to the detection of how much states of rail.At present, Some Domestic road bureau has adopted track detection car to detect the static parameters such as track centre position, tread elevation, gauge and superelevation, part road bureau still adopts the traditional means such as track forces to measure the rail geometry parameter, but the detection of rail creeping amount relies on people's naked eyes to be identified in conjunction with the monitoring stake substantially, the method measuring accuracy is low, error is large, can't meet the modern railways requirement.Roadbed frost heave and thaw collapse displacement monitoring are mainly measured by burying displacement transducer underground, and the method need to be buried monitoring equipment underground in earlier stage, and workload is large, and both are not suitable for wired roadbed displacement monitoring.
Technology contents
The utility model proposes a kind of simple in structure, accurate accurately, reliability is high, without the creep device of displacement and vertical deviation of construction in early stage, the measurement railway track that do not take Window time.
A kind of creep device of displacement and vertical deviation of railway track of measuring, comprise figure line sheet, foundation pile, video camera and server, described foundation pile is arranged on a side of rail, described video camera is arranged on described foundation pile and aims at described rail, the output interface of described video camera is provided with processor, described figure line sheet be arranged on rail surface on the side of described video camera and described figure line sheet in the angular field of view of described video camera, described figure line sheet is provided with is convenient to described processor by the background color pattern of the image recognition after described camera acquisition and foreground pattern, described processor is connected with described server by wireless transport module.
Described video camera adopts bicamera, and two camera lenses of described video camera are aimed at respectively two rail of uplink and downlink, and described figure line sheet all is installed on described rail.
Described wireless transport module adopts the GPRS module that the geodata and services device is connected.
Described figure line sheet is arranged on the web of the rail of rail.
The utility model adopts such scheme, owing to belonging to non-contact measurement, do not affect traffic safety, without taking Window time, highly effective and safe, save manpower, adopt computer graphics techniques to be measured simultaneously, effectively guaranteed measuring accuracy, reduced measuring error, solved the larger problem of naked eyes estimation error, adopt Radio Transmission Technology, Servers installed is carried out in administrative authority to the Data Collection management, make creep displacement and the vertical deviation of the understanding rail that the staff can be real-time, can to the disease rail, be safeguarded in time, greatly improved work efficiency, be convenient to the centralized management of data simultaneously.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
The schematic diagram that Fig. 2 is the utility model figure line sheet;
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, a kind of creep device of displacement and vertical deviation of railway track of measuring, comprise figure line sheet, video camera and three parts of server, and video camera 1 is laid on the foundation pile 2 of track one side; Video camera 1 adopts twin-lens to gather respectively the displacement information of two circuit rail of uplink and downlink, by the computational analysis of internal processor, obtains the displacement of four one steel rails, then via the GPRS module by the data back server; Figure line sheet: on 4 outline lines that intersect at the Zhong Fen plane, shooting visual angle of video camera and rail, the web of the rail line that the outline line of take faces video camera is the fixing figure line sheet 3 of center line, and background color and the foreground contrast of figure line sheet 3 are high, are convenient to the processor discriminance analysis; Server: build-in services device in the administrative authority of railroad section, carry out concentrated equipment to all video cameras of railroad section and control and the data receiver management; Figure line sheet is fixed on steel rail web.
In the present invention, by computer graphics techniques, analyze rail creeping displacement and vertical deviation (frost heave and thaw collapse).
Video camera is fixed on the foundation pile 2 of circuit one side, and any motion is not installed, and guarantees measuring accuracy, in order to measure rail creeping and vertical deviation in picture.Server is arranged on the administrative authority of railroad section, concentrate and to carry out Data Collection, make creeping and frost heave (thaw collapse) displacement of understanding rail that the staff can be real-time, can be safeguarded the disease rail in time, greatly improve work efficiency, be convenient to the centralized management of data simultaneously.
Measurement scheme of the present invention can be improved measurement result by computer graphics techniques, improves measuring accuracy and efficiency, reduces to measure the error produced while calculating.In addition, adopt Radio Transmission Technology, what energy was real-time passes measurement data back administrative authority, facilitates the related personnel rushed to repair timely and safeguard.
