Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are further elaborated:
A kind of transformer station high-voltage circuit-breaker status signal pickup assembly comprises camera head 1, cover body 2, and described cover body 2 is installed on the breaker body 3; Camera head 1 is installed on the described cover body 2, the information that is used to gather circuit breaker indication plate 4.
Described transformer station high-voltage circuit-breaker status signal pickup assembly also comprises magnet proximity switch 5, and described magnet proximity switch 5 is installed in the two ends of stroke of the lever arm 6 of circuit breaker.
Described transformer station high-voltage circuit-breaker status signal pickup assembly also comprises logic and message handler 7, and described magnet proximity switch 5 links to each other with logic and message handler 7, is used for the information of magnet proximity switch 5 is analyzed.
Described logic and message handler 7 also comprise picture recognition module, and described picture recognition module links to each other with camera head 1, are used for the information that camera head 1 is gathered is discerned.
Described logic and message handler 7 judge whether the information that camera head 1 gathers is consistent with the object information of magnet proximity switch 5, if during the information unanimity, and the transmission object information; If information inconsistency then sends warning message to the upper level system.Described upper level system is not included in the present invention, refer to and can receive the information that this device sends out, for operating personnel with reference to usefulness.
The device of described transmission information can be any one or a few in optical fiber, cable, Ethernet, GSM, 3G communication, ZigBee, WIFI, the bluetooth.
Described camera head 1 is an industrial camera, described industrial camera adopt have a day night vision, focus, antifog, anti-or the industrial camera of several functions in the rain.
Described cover body 2 is transparent cover or the cover body that is provided with visual windows.
Described cover body 2 is square or cuboid or hemisphere.
Described camera head 1 apart from circuit breaker indication plate 4 less than 200mm.
As shown in Figure 1, the output of this device has two kinds of signals, and the one, without the vision signal of processed, the image of reflection circuit breaker indication plate 4 real-time statuss.The 2nd, pass through the signal that this device analysis was handled, " close " as " branch " and upload to control centre respectively.
The present invention has adopted subminiature industrial camera, the body that directly is installed on circuit breaker is closely lacked the monitoring of focal length to the shift position of indication plate 4, and the color symbol of indication plate 4 carried out particular processing, make microcam can very easily tell mark and the position that indication plate 4 is manifested.
Logic and message handler 7 that the present invention adopts are the Embedded ARM micro computer devices based on DSP, comprise functional modules such as logic determines, image recognition, have functions such as logic determines, image recognition.
By logic and message handler 7, use the intelligent image mode identification technology that " branch ", " closing " are discerned, what action was monitored as circuit breaker simultaneously replenishes, it mainly is the connecting rod landing fault that prevents indication plate 4, prevent that promptly switch from moving, but also having designed, the situation that indication plate 4 fails to move, this device use the means of supplementing out economy of magnet proximity switch 5 as field monitoring.
As shown in Figure 2, at the stroke two ends at the whole story of the lever arm 6 that links to each other with circuit breaker operation mechanism 8 magnet proximity switch 5 has been installed.During operating breaker operating mechanism 8 connecting rods, lever arm 6 is in position A, position B respectively, respectively near the magnet proximity switch 5 of relative position.Simultaneously, the indication plate 4 of circuit breaker indicates " branch " " to close " state respectively.When
The importance of this device is: owing to also exist the mechanical breakdown situation of operating mechanism 8 and indication plate 4 in the electric substation in the on-the-spot reality, therefore logic of the present invention and message handler 7 are provided with the self-checking function of signals collecting, can find promptly whether circuit breaker operation mechanism 8 is consistent with indication plate 4 actions.Such as the state of the indication plate 4 that identifies when picture recognition module during for " closing ", but the state of magnet proximity switch 5 monitorings of lever arm 6 still be " branch ", and this device promptly starts alarm signal, and indication plate 4 machineries of representing to open circuit have fault; If the state consistency of the state of the indication plate of image recognition 4 and magnet proximity switch 5 monitorings then sends normal circuit breaker " branch " or " closing " signal, and is sent to operating personnel by communicator.
Because IMAQ and identification are separate incidents with magnet proximity switch 5 monitorings, therefore can judge the state of circuit breaker more accurately under situation about being independent of each other, and improve the reliability of judged result information.
What the cover body 2 of this enforcement adopted is the bright square cover body of full impregnated, is fixedly mounted on the breaker body 3, covers on hermetically on the indication plate 4 of circuit breaker.The industrial camera that adopts has a day night vision function, and video camera and logic and message handler 7 are installed on the cover body 2, and the distance of the indication plate 4 of industrial camera and circuit breaker is 200mm.
