Data association table main contents on information and the video storaging equipment
The video image information Intelligent Recognition
The splicing control module can be carried out Intelligent Recognition to equipment state on the video image or parameter, when great amount of images shows simultaneously, helps the user to find emphasis rapidly, improves the ease for use of system.
Apparatus for establishing characteristics of image and position feature storehouse.The linkage control device Installation and Debugging stage starts and to build library facility, and the autoscan video image, is artificially confirmed to combine intellectual analysis, manual setting, and information such as the characteristics of image of the equipment of required monitoring and state and position feature are carried out record.Install and in servicely also can start identification at any time, increase or edited image characteristic and position feature storehouse present image.
State to equipment is discerned, the following recognition strategy of general employing: in each duty difference images acquired of equipment, carry out the graphical element analysis, and comparing difference, record key element and difference, and the presetting bit of video camera etc.When needing identification, retrieve comparison together by this key element, difference, presetting bit.
The peculiar recognition strategy one of energy production conveying equipment: important color identification.A lot of equipment all have red when opening or closing or the green light indication, and certain state red light is bright, green light goes out, and the bright lamp mode of each state is different, and the brightness of carrying out redness or green in the key area changes relatively, can reach the purpose of state recognition.
The peculiar recognition strategy two of energy production conveying equipment: important lines and angle identification.Need arrive ad-hoc location during a lot of equipment operation, could operate as normal.Such as: the electronic disconnecting link of power transmission and distribution, six pivoted arms of three-phase must change into three straight lines and could contact well; If disconnecting link not contact is good, or separation not yet in effect, all may produce major accident.The splicing control module can be identified as six straight line key elements to six pivoted arms of electronic disconnecting link three-phase, if these six straight line key elements become three longer straight line key elements, the expression disconnecting link forwards to and closed the position; Becoming six parallel straight line key elements, then is that correct separating brake has put in place.After the splicing control module was discerned this image information, recognition result in time superposeed on picture.
The user should when edited image characteristic and position feature storehouse, choose different recognition strategies according to different equipment situation, or many strategy combinations, to improve the correct recognition rata of system.
Video image information strengthens
The splicing control module can be on video image according to the parameter that is provided with dynamically superpose display graphics, sign flag or literal so that the content of the easier observation video image of user, the readability of enhanced information.
Set up video image and strengthen the mode storehouse.The device Installation and Debugging stage starts and to build library facility, and the autoscan video image, is artificially confirmed to combine intellectual analysis, manual setting, and information such as the characteristics of image of the equipment of required monitoring and state and position feature are carried out record; Setting simultaneously needs stack symbols displayed, literal and display mode.Install the information stack that also can start present image in service and strengthen, increasing or edit need sign and symbols displayed or information.
When linkage control device normally moves; The interlock control module is searched the data association table to the change events that takes place; The control video camera changes the presetting bit of appointment; The splicing control module strengthens the mode storehouse according to the position feature query image of video camera, and the facility information in video image and the mode storehouse is compared, and confirms the position of equipment in image; The mode that strengthens the mode lab setting by video image is handled video information, the figure, symbol and the literal that in video image, dynamically superpose and be provided with.
When equipment is movably, equipment characteristics of image position and size on video image can change, and the information of stack also will move with sports equipment on image, keep the effective sign to equipment.
During camera lens rotation convergent-divergent, the position feature of video camera can pass to the splicing control module, and the information of stack also will move or convergent-divergent with equipment on image, keep the effective sign to equipment.
The present invention and usual manner relatively have following advantage:
One, control of energy plant station video and large screen display control become the data linkage Automatic Positioning Control by manual control.
In that event occurs when the user need see video, native system plays the video that window shows equipment needed thereby automatically on splicing large screen, and the user need not numerous and diverse operation.
For example during dispatching of power netwoks person's straighforward operation; If the yardman wants the on-the-spot motion images through the operated equipment of video-see; Because of factory station video monitoring equipment and dispatching automation equipment respectively in different electrical production network security districts; The yardman need arrive manually-operated video monitoring system on the special purpose computer of another video monitoring; And in thousands of cameras, find the video camera that will see, and must clearly know the accurate position of the equipment that will see, with camera lens convergent-divergent, sense of rotation equipment position.General provincial traffic department is responsible for hundreds of factory stations, and video camera has several thousand, and the equipment that these video cameras will be kept watch on reaches several ten thousand, and to carrying out manually-operated in a large amount of control point like this, all too difficulty does not have practicality to say.Native system wants the associated picture video intelligent ejection of apparatus operating to be presented on the splicing large-size screen monitors yardman, does not need the yardman that extra operation is arranged, and uses easily; And what be delivered to that large-size screen monitors show is video data, does not have network security risk.
Two, video image intelligent identification improves the energy production security, strengthens user's ease for use.
For example: the electronic disconnecting link of power transmission and distribution, six pivoted arms of three-phase must change into three straight lines and could contact well; If disconnecting link not contact is good, or separation not yet in effect, may produce major accidents such as arc discharge, scaling loss disconnecting link.And the traditional device state all is by travel switch identification, if six pivoted arms within an ace of do not forward the position to, then travel switch possibly move, causes information errors; Put in place if there is part not move in addition in the three-phase, travel switch detects and can't find equally.
This generic operation generally is to need watch's execute-in-place disconnecting link now, the result is confirmed efficiency is low.If adopt the Remote operation, carry out artificial cognition through video image again, often need manual work to adjust video camera repeatedly, troublesome poeration puts in place because of the operator schemes convenient not inspection easily, cause the accident, so the ratio that the Remote disconnecting link is used is not high.The splicing control module can be identified as six straight line key elements to six pivoted arms of electronic disconnecting link three-phase, becomes three long straight line key elements, and the expression disconnecting link forwards to and closed the position; Becoming six parallel straight line key elements, then is that correct separating brake has put in place.After splicing controller was discerned this image information, the recognition result that in time on picture, superposes improved the security of operating greatly.
Three, dynamically superpose graphical symbol or Word message of video image, the readability of enhanced information.
When information change, eject on the video image displayed, native system superpose automatically related symbol or literal identify device location or the status information relevant with this data variation information, and video image is strengthened, and make things convenient for User Recognition.
For example native system can be labelled frame of the equipment of current straighforward operation stack, and handled easily person under the too many situation of number of devices, also can very clearly see the remote-operated equipment that needs rapidly at the scene; The native system literal that superposes simultaneously identifies the title of this equipment, state, and handled easily person observes affirmation.
This mode can prevent effectively that also maloperation from arriving miscellaneous equipment; If because the regulation and controlling of information acquisition module obtains is the telecommand of another equipment; Then can frame be added on another equipment; The number information that shows another equipment simultaneously, the operator can notice at once that the operation of controlling oneself maybe be wrong.
