Background technology
Along with railway electrification development degree in recent years is more and more higher, the advantage of its electric railway operation is mainly reflected in advantages such as transport capacity is big, travel speed is fast, consumes energy is few, operation cost is low, good operation conditions, to the big main line railway of freight volume and have the abrupt slope, the mountain area main line railway in the tunnel of growing up realizes electrifiedly, and obvious superiority is all arranged technically, economically.To be the pantograph that carries by train with railway contact line along the line contact the supply power mode of railroad train gets stream.
In bow net (being pantograph and the contact line) dynamic running process, bow net operation relative distance, the lifting bow time, the off-line time in the running (the off-line time refers to that bow net divides ETAD expected time of arrival and departure) requires very strict, if there is not mode according to the rules to work, can cause and scrape bow, burn great driving accidents such as line.
The utility model content
Goal of the invention of the present utility model is: provide a kind of railway bow net dynamic operation digital video monitoring device at the problems referred to above, by being installed near the digital high-definition video camera the pantograph, in conjunction with contact line dynamic monitoring parameter, pantograph rising, decline, the mutual running status of bow net are monitored in real time.Can effective monitoring bow net on-line operation state in conjunction with sensing chamber's monitor, pinpoint the problems early lifting bow running time, effectively reduced the generation of bow net run case such as scraping bow, burning line.
The technical solution adopted in the utility model is such: comprise digital camera, catenary ' s parameters detecting unit, processor, video distributor and a plurality of video-frequency monitor; Described digital camera is installed on the train top and is positioned near the pantograph, is used for gathering the realtime graphic of bow net dynamic operation; The digital picture output of digital camera is connected with an input of processor; Processor also has signal with the catenary ' s parameters detecting unit and is connected; Processor is used for catenary ' s parameters with the form of the captions digital picture that is added to, and the view data output of processor is connected with the input of video distributor; Video distributor is used for that one tunnel view data demultiplexing video and correspondence are exported to described a plurality of video-frequency monitor and shows.
Preferably, also comprise secondary light source; Described secondary light source is positioned at the train top and is positioned near the pantograph.
Preferably, the parameter of described catenary ' s parameters detecting unit output is to lead at least a in height, stagger, bow net dynamic operation pressure or the bow net dynamic impulsion acceleration.
In sum, owing to adopted technique scheme, the beneficial effects of the utility model are:
1, being installed near the digital high-definition video camera of pantograph gathers the bow net state in real time, at last by the video-frequency monitor output that is distributed in each Control Room, the staff can be real-time, see the operating state of pantograph and contact line intuitively, pinpoint the problems early, effectively reduced the generation of scraping bow, burning bow net run case such as line.
2, utilize the digital camera associative processor that the catenary ' s parameters of catenary ' s parameters detecting unit output is presented on the video in conjunction with the stack of bow net dynamic video, can provide more accurately bow net operation information for the staff.
3, near the pantograph of train top, secondary light source is installed, under Night, tunnel, the bad situation of illuminating position, digital camera is carried out the light source subsidy, improved the video camera recognition capability.
