Description
Technical field
The utility model is related to railcar monitoring field, specifically a kind of railcar roof pantograph foreign matter inspection
Examining system.
Background technology
Pantograph is the electrical equipment that electric locomotive obtains electric energy from contact net, on power locomotive top, electricity
Power locomotive pantograph during high-speed cruising can ceaselessly contact friction with contact net and obtain electric energy.Railcar pantograph
Run outside tunnel or in foreign matters such as the polybag for going out float when the open-air atmospheres such as warehouse-in run, paper, rope, balloons
Easily it is wrapped on pantograph pan, in tunnel, metal connector of installation equipment etc. is likely to drop and is wrapped in pantograph
On slide plate, hidden danger is brought to power supply safety.When occurring foreign matter on pantograph pan, to the power supply safety of electric locomotive and can connect
The inherently safe of net-fault equipment brings threat, it is therefore desirable to which the foreign matter on pantograph pan is monitored, when find compared with
Big foreign matter needs timely parking process when being attached on pantograph pan.
But as railcar operates in tunnel internal, once behaving the state that cannot just see pantograph, equipment
Health status enters monitoring blind area, it is therefore desirable to which a set of monitoring system can be monitored to vehicular traffic pantograph, finds different
Reason condition and alarm, so as to quick process.
Utility model content
For the deficiencies in the prior art, the utility model provides a kind of on-line monitoring system based on image recognition technology.
The high-definition image of pantograph is shot by the video camera in tunnel, is then known by computer intelligence image recognition algorithm
The foreign matter in other pantograph pan face.
The technical scheme adopted for achieving the above object by the utility model is：
A kind of railcar roof pantograph foreign matter detection system, pantograph candid camera are calculated by Ethernet connection
Machine, the image information for gathering pantograph are sent to computer；
License number detects that video camera connects computer by Ethernet, and collection license number image information is sent to computer；
Wheel detector connects computer by serial ports, gathers the wheel signal of current driving vehicle, is sent to computer,
Judge that vehicle arrives or sails out of.
The pantograph candid camera is that resolution ratio is at least 2592*1944, and frame per second is at least 25 frames/second, and image is passed
Sensor size is at least 1 inch of face battle array industrial camera.
The license number detection video camera is that resolution ratio is at least 720P, and frame per second is at least 100 frames/second, and imageing sensor is adopted
With the face battle array industrial camera of global shutter cmos sensor.
The wheel detector is arranged on the inside of track.
The wheel detector is electromagnetic sensor, can by train wheel near when the changes of magnetic field that produces be converted to electricity
Signal.
It is the short message sending terminal using GSM network also including warning device, computer is connected by serial ports, receives and calculate
The warning message that machine sends, sends alarming short message to specified mobile phone number.
The utility model has the advantages that and advantage：
1. the utility model detects video capture vehicle vehicle number information by license number, makes information of vehicles and gathered data one
One correspondence, is conducive to finding foreign matter vehicle；
2. the utility model can accurately tell foreign matter by the pantograph picture that pantograph candid camera is captured,
Image data can be transferred in malfunction analysis procedure, easy-to-look-up foreign matter source is car inspection and repair, plant maintenance and after
Trouble-saving provides condition；
3. the utility model carries out image recognition automatically, realizes unmanned when 24 hours, without the need for manually looking into figure, reduces people
Work workload, reduces system use cost；
4. it is of the present utility model that warning message is fed back in time by related personnel by warning device, foreign matter is reduced to vehicle
The follow-up impact of operation.
Description of the drawings
Fig. 1 is system architecture connection figure of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawings and embodiment is described in further detail to the utility model.
It is illustrated in figure 1 system architecture connection figure.
Pantograph candid camera connects computer by Ethernet, and the image information for gathering pantograph is sent to calculating
Machine.License number detects that video camera connects computer by Ethernet, and collection license number image information is sent to computer；Wheel detector
Computer is connected by serial ports, the wheel signal of current driving vehicle is gathered, is sent to computer, judge that vehicle arrives or sails
From.
When railcar enters monitored area, wheel detector notifies after sensing signal that calculating rolling stock arrives.Meter
Calculation machine opens each video camera successively and light compensating lamp starts to gather pantograph image and license number image, after vehicle is left away closes phase
Machine and light, into image recognition program.If it find that defect is then sent on the mobile phone of specified director by warning device
Alarm message ceases, and informs which finds pantograph pan foreign matter in certain time, certain vehicle.
Each equipment is described as follows：
Wheel detector：The electromagnetic sensor based on magnetic induction principle being mounted on the inside of track, when train wheel is leaned on
During nearly sensor, then sensor produces electric signal, back-end processing equipment sense after the electric signal after filtering, shaping, digitlization
Etc. passing to after process, calculating carries out carrying out car, picking up the car judges.
Pantograph captures camera：Pantograph captures the high speed high-definition camera that camera is an integrated light compensating lamp, its response
External trigger signal time is less than 1ms, and compared with common camera, its response time is shorter, can capture the target that passes through at a high speed and
Guarantee to capture the uniformity of position every time.
The pantograph picture shot by high-definition camera can accurately tell foreign matter, the energy in malfunction analysis procedure
Image data is transferred enough, easy-to-look-up foreign matter source is car inspection and repair, and plant maintenance and later trouble-saving provide condition.
Computer：Operation kernel software and intelligent analysis process, software obtain pantograph high definition snapshot by communication protocol
Image carries out intellectual analysis, it is found which has foreign, provides warning information service host in time when foreign matter is found.
Warning device：Warning device is the short message sending terminal of a set of use GSM network, and software can be by which to specified
A number of phone number sends note, reaches the purpose for notifying relevant work personnel in time.Component computer is carried out automatically
Image recognition, realized unmanned when 24 hours, without the need for manually looking into figure, reduces labor workload, reduces system use cost.
License number detects video camera：It is that resolution ratio is at least 720P, frame per second is at least 100 frames/second, and imageing sensor is using complete
The face battle array industrial camera of office's shutter CMOS sensors.
In system, the image of license number collected by camera can be captured through the license number during software recognizer identifies shooting image
Image and license number are man-to-man during data storage and management, can directly be transferred by license number when enquiry of historical data
All historical datas of the car.
