Description
Technical field
The present invention relates to field of image recognition, and more precisely, being related to a kind of pantograph in track traffic should to contact net
The detection method and device of power.
Background technology
Contact net is the transmission line of electricity for the special shape powered to electric locomotive that downline overhead is set up.Contact net is carried on a shoulder pole
Bear the vital task that the electric energy obtained from traction substation is delivered directly to electric locomotive and used.Therefore the quality of contact net
The transport capacity of electric railway is directly affected with working condition.
In high-speed electric railway system, it is necessary to keep stable by stream mode, it is desirable to which pantograph will have with contact net
Certain contact, when contact is too small, have resulted in offline, i.e., pantograph disengages line and produces electric arc；When connecing
When touch pressure is excessive, contact line Uplifting amount is excessive so that contact line local buckling, causes contact line fatigue damage, while makes to connect
Line abrasion increase is touched, accident between pantograph is caused when serious.
The patent No.：200720082607.4 a kind of contact pressure of motorcycle pantograph dynamic on-line monitoring device, the device are adopted
With pressure sensor mechanical system, structure is big, and it is inconvenient that weight pole re-mounts maintenance, therefore, it is necessary to research and develop it is a kind of suitably by
Pantograph is to contact net stress mornitoring mode and device.
The content of the invention
For problems of the prior art, contact net stress is examined it is an object of the invention to provide a kind of pantograph
Device is surveyed, the device can be monitored to the stress state of pantograph contact net, and its cost is cheap, and accuracy of detection is high, uses peace
It is complete convenient；Reliable and stable, area occupied is few, it is only necessary to installs one group of camera, service life length non-contact with contact net.
In order to realize the purpose of the present invention, the technical solution adopted by the present invention is as follows：A kind of pantograph is to contact net stress
Detection means, system include camera, white background plate, background board flash lamp, trigger sensor, stretching force detecting apparatus, camera
To be installed with white background plate and contact net same level, stretching force detecting apparatus tail end is arranged on detection greenhouse maintenance platform,
Top is stuck on carrier cable, to keep stretching force detecting apparatus (structure) into horizontality.Normal condition bottom offset=0mm, pressure
=0N.Contact net often draws high 5N, and camera is shot, and draws corresponding pixel value；Then marked by camera and contact net distance
Surely 1 pixel actual size is drawn, carrying out conversion with corresponding pixel value draws actual displacement value, generates one group《Displacement is with drawing
Chart corresponding to power》；When the equipment is attached to some test point, it is only necessary to carry out a pulling force before power-off is open to traffic and demarcate
Go out corresponding chart；When pantograph passes through trigger sensor above train during later stage train detection, camera shoots one group of contact net
Raised photo when being contacted with pantograph, according to photograph pixel value with《Displacement chart corresponding with pulling force》Contrast draws actual drawing
Force value.
A kind of pantograph of the present invention comprises the following steps to the detection method of contact net stress：Camera and white background
Plate is installed with contact net same level, and stretching force detecting apparatus one end is arranged on pantograph detection greenhouse maintenance platform, another
End is stuck on carrier cable, keeps stretching force detecting apparatus into horizontality；Normal condition bottom offset=0mm, pressure=0N；Contact net
Certain numerical value is often drawn high, camera is shot, corresponding pixel value, draws actual shift value by demarcation, while form one
Group displacement chart corresponding with pulling force；When the equipment is attached to some test point, it is only necessary to carry out a pulling force when mounted
Demarcation draws corresponding chart, and the later stage, which crosses car, only needs one group of camera to be shot with regard to that can calculate stress data.
Installing contact net pressure detecting caliberating device, contact net pressure detecting demarcation is first carried out, is comprised the following steps：
1.1st step：Stretching force detecting apparatus top is stuck on carrier cable, it is flat that end is fixed to pantograph detection greenhouse maintenance
On platform；
1.2nd step：Locked after by level meter, stretching force detecting apparatus is adjusted to horizontal level；
1.3rd step：Winder is adjusted, hook is hooked on carrier cable, ensures that drag hook and fixed pulley are in vertical position,
When display pressure value is shown as 1N values, when slowly loose rotary wheel device is to 0N, Winder is braked, pressure sensor peeling
It is set to zero-bit；
1.4th step：Hand runner is rotated, contact net often draws high certain numerical value, and triggering camera is taken pictures, so as to draw
《Displacement chart corresponding with pulling force》.
Beneficial effects of the present invention are：The system architecture of the present invention is simple, it is only necessary to carries out a pulling force mark when mounted
Surely draw《Displacement chart corresponding with pulling force》, the later stage, which crosses car, only needs one group of camera to be shot with regard to that can calculate stress data
Pantograph working position contact value is drawn, is contactless state with contact net, is not in contact net damage structure or knot
Structure damages contact net situation.The pantograph of the present invention has small volume, easy for installation, maintenance to contact net stress detection device
The features such as property.
