Abstract
The invention discloses a pantograph carbon rod abrasion value measurement system comprising a gantry tool, a strip-shaped light source group module, a camera/lens group module, a camera shooting window, and laser sensor pairs. The strip-shaped light source group module is mounted at the front and rear sides of the horizontal beam of the gantry tool. The camera shooting window is disposed inside the camera/lens group module. The camera/lens group module is mounted on the vertical beam of the gantry tool. The laser sensor pairs are mounted at the front and rear sides of the strip-shaped light source group module. A claw detection module is arranged between the strip-shaped light source group module and the camera/lens group module. The pantograph carbon rod abrasion value measurement system is modular and integrated. The detection function modules can be separately integrated or disassembled, so that the modules are easy to maintain or a detection module group with new functions is easy to add. The high-resolution camera can quickly capture carbon rods and claws on a running train, and the abrasion degree of pantograph carbon rods, the offset of the center position and the claw detects can be detected in a scalar manner through an accurate image correction technology.
Description
Technical field
The present invention relates to pantograph detection technique field, specifically a kind of pantograph carbon rod wearing valve measuring system.
Background technology
Pantograph is that electrically-driven car obtains the electrical equipment of electric energy from contact net, is arranged on locomotive or motor-car roof.Pantograph characteristic directly has influence on the operation stability of electrically-driven car, therefore detects timely and effectively ensureing that the safe and stable operation of locomotive is significant its pantograph characteristic.Static Contact pressure when electrically-driven car pantograph characteristic refers to that ascending, descending is bent and lifting bends the variation relation of height and be elevateds the relation etc. bending highly and be elevated the bow time.Static Contact pressure is bent in the lifting of pantograph, height is bent in lifting and the lifting bow time can reflect pantograph characteristic.Therefore the mensuration of pantograph characteristic is many was realized by detection pantograph pressure, lifting bow height, lifting bow time.Current domestic a lot of pantograph checkout equipment cannot realize the remote transmission of pantograph when detecting pantograph characteristic, cannot realize measuring the effective combination with data acquisition.
Summary of the invention

Embodiment
Be described in more detail below in conjunction with the technical scheme of embodiment to this patent.
Refer to Fig. 1-7, a kind of pantograph carbon rod wearing valve measuring system, comprise portal frame frock 1, strip source group module 2, camera/lens group module 3, camera shooting form 4 and laser sensor are to 5, described portal frame frock 1 is arranged on the periphery of train rail 7, described strip source group module 2 is arranged on front side and the rear side of the crossbeam of portal frame frock 1, described crossbeam is positioned at the top of tested carbon-point group 6, described camera shooting form 4 is positioned at camera/lens group module 3, described camera/lens group module 3 is arranged on the vertical beam of portal frame frock 1, described laser sensor is arranged on the both sides, front and back of strip source group module 2 to 5, goat's horn detection module 8 is also provided with between described strip source group module 2 and camera/lens group module 3, described tested carbon-point group 6 is arranged in tested shelf goat's horn group 9.
All module frocks have dust-proof, moistureproof, vibrationproof, function against pressure, avoid the aerodynamic collision owing to causing in train traveling process, cause the skew of camera position to cause the instability of camera imaging; Camera is arranged in shell frock, and this camera model frock is hermetically sealed protection, and industrial level is IP69.
Image zooming-out 50 groups of sampled points of provided carbon-point sample are measured, and the result of measurement is presented on picture, find carbon-point lower edges boundary and by range observation out, by the calculating of computer, the process at 50 groups of edges time used is within 300ms, later when truly applying, about 200 groups can be increased to according to field condition, measurement is reached become more meticulous, can draw by experiment, the exact value measuring wearing valve can realize, can quantitatively detect with subway, light rail and high ferro be representative the dynamic car body of track traffic on the wearing valve of pantograph and the defective eigenpairs of goat's horn.
Described pantograph carbon rod wearing valve measuring system operationally, light source G1, G2, G3, G4 Chang Liang, laser L1, L2, L3 Chang Liang; Camera A, B, C, D are in preparation shooting state, and when train enters measured zone, pantograph stops the laser beam of laser sensor L1, and camera A starts working, the E face of shooting pantograph carbon-point T1; Train advances, and pantograph stops the laser beam of laser sensor L2, and camera C and D starts working, shooting be four goat's horns of pantograph; Train moves on, and pantograph stops the laser beam of laser sensor L3, and camera B starts working, shooting be the F face of pantograph carbon-point T2; After each shooting, computing machine can process picture immediately and extract data.
When described camera A takes carbon-point E side, image rectification algorithm corrects E side, image denoising, gray-level correction algorithm, rasterized images definition grid units, adopt the thickness of carbon-point E side profile extraction algorithm Scalar operation carbon-point E side, contrast standard shelf and carbon-point image, judge whether that pantograph center deviation difference and carbon-point levelness exceed definition tolerance value, then record carry out sound and light alarm, no then records data, store picture, generate form, building database; When described camera C and D takes goat's horn, image denoising, gray-level correction algorithm rasterized images definition grid units, contrast standard goat's horn image, has judged whether goat's horn defect or disappearance, be record and sound and light alarm, otherwise record data, storage picture, generation form, building database; When described camera B takes carbon-point F side, image rectification algorithm corrects F side, image denoising, gray-level correction algorithm rasterized images definition grid units, adopt the thickness of carbon-point F side profile extraction algorithm Scalar operation carbon-point F side, contrast standard shelf and carbon-point image, judge whether that pantograph center deviation difference and carbon-point levelness exceed definition tolerance value, be, record and sound and light alarm, otherwise record data, storage picture, generation form, building database.
The present invention has the feature of modularization, integration, and each measuring ability module can distinguish integrated or dismantle, and is convenient to the detection module group that module maintenance or increase have New function; High resolution camera can be captured fast and exercise carbon-point on train and goat's horn, by image flame detection technology accurately, can the wear intensity of scalar detection pantograph carbon-point, the skew of center and goat's horn defective eigenpairs.
