Description
Technical Field
The invention belongs to the technical field of automatic point-to-point acceptance of graphic pictures of a power dispatching system, and particularly relates to an automatic point-to-point acceptance method of graphic pictures of the power dispatching system.
Background
With the continuous popularization of unattended substations, the premise that each stage of dispatching center can accurately monitor the governed substations in real time is that the power grid operates safely and stably, and remote transmission area point table information of a dispatching master station and a plant station end needs to be verified. The signal point-to-point and acceptance of the main station side of the power dispatching system basically adopts manual checking of signal information in a real-time power graphic picture of the dispatching main station system. The method brings great workload to dispatching workers, is low in efficiency, is easy to generate careless omission, and brings hidden danger to the safety of a power grid.
The original correlation error between the graphic element and the actual signal in the power graphic picture often exists, and the remote signaling signal value has point aligning failure in the point aligning test. The remote signaling signal state in the electric power graphic picture is 'on' or 'off', and the electric power graphic picture of the remote signaling signal in different states is different, including different shapes, colors and flashing states, and brings difficulty to the identification of the remote signaling signal.
Therefore, it is necessary to research a more intelligent, more efficient and safer automatic point-to-point acceptance method for a scheduling-side graphic picture, so as to reduce the burden of workers, improve the work efficiency of point-to-point acceptance, and improve the correctness of point-to-point and picture association.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: the utility model provides an automatic checking and accepting method for the graphic picture of the power dispatching system, which solves the problems in the prior art.
The technical scheme adopted by the invention is as follows: a method for automatically checking and accepting graphic pictures of a power dispatching system comprises the following steps:
The point-to-point signals are sequentially and periodically sent out by the station according to the point-to-point list to be checked, and the electric power graphic picture automatic point-to-point acceptance method sequentially carries out point-to-point acceptance according to the point-to-point list to be checked. The method adopts identification of point-to-point signals in an alarm window, is carried out in a scheduling master station, firstly sends out the point-to-point signals in sequence on a transformer substation side, then sequentially checks the point-to-point signals in the alarm window in a scheduling system on the master station side, and the sent-out signals and the check signals are not related with each other but are synchronous in progress. The method has the advantages that: and checking the integrity of a link of the point-to-point signal, wherein the link comprises a plant station side telecontrol device and a master station side scheduling system.
The remote signaling signal states are divided into 0 and 1, the electric power primitive pictures of the remote signaling signals in different states are different and comprise different shapes, colors and flashing states, when the electric power primitive pictures of the signals are subjected to image recognition, a plurality of picture pictures are required to be continuously intercepted, the flashing state of the electric power primitive of the point signal is intercepted, the flashing time of the electric power primitive in the electric power picture is known to be fixed, the time interval for continuously intercepting the electric power picture is set as 2/3 of the primitive flashing time interval, the number of the continuously intercepted electric power picture is 5, so that the flashing state of the electric power primitive of the point signal is obtained, when the signal primitive of the flashing state is subjected to image recognition, as long as one electric power picture captures and recognizes that the signal primitive is 'bright', the signal is considered to be in the 'flashing state'. The method has the problems that the graphic elements of the remote signaling signals have flashing states, the information of the graphic elements of the remote signaling signals cannot be confirmed only by identifying one picture, and a plurality of pictures need to be intercepted to obtain the flashing states of the electric power graphic elements.
The image recognition method for the remote signaling signal primitive is used for recognizing the color on the middle point, the vertical center line or the specific area of the primitive to judge the state of the remote signaling signal primitive. The specific identification logic is as follows:
and for the graphic elements of the circuit breaker in the remote signaling signal, a method for identifying the color of the central point is adopted. If the central point of the circuit breaker primitive is identified as black, judging that the state of the circuit breaker primitive is 'fen'; if the central point of the breaker primitive is identified to be red, judging that the state of the breaker primitive is 'sum';
and for the graphic elements of the optical word plate in the remote signaling signal, a method for identifying the colors of two ends of a vertical center line is adopted. The vertical central line takes the color of dots from top to bottom, the color of dots from bottom to top, if yellow is taken twice, the state of the light character board primitive is judged to be 'fen'; if the color of the light word board is red in the two times, the state of the primitive of the light word board is judged to be 'combined'; if the colors acquired in the two times are not consistent or the color acquired in the one time is not acquired, reporting that the identification is abnormal;
and for the graphic elements of the knife switch in the remote signaling signal, a method for identifying the colors of specific square area in the graphic elements is adopted. If the color (not black) is identified in the specific square frame area, judging the state of the knife switch primitive to be 'minute'; if no color, namely black, is recognized in the specific square frame area, the state of the knife switch primitive is judged to be 'closed'.

And selecting a position and a size area of the point signal to be aligned in the preprocessed electric power graphic picture, and identifying the picture area. Dividing the signals to be aligned into remote measuring signals and remote signaling signals, adopting tesseract to identify the images of the signals to be aligned for the remote measuring signals, and obtaining the magnitude of signal remote measuring values in the electric power graph; for remote signaling signals, an electric power primitive recognition technology is adopted to recognize signal images to be aligned, and the states and remote measurement values (on or off) of signal elements in the electric power images are obtained.
And finally, checking whether the electric power pattern point signal image identification result to be aligned is the same as the point signal value to be aligned: if the identification result is the same as the value of the signal to be aligned, the signal is aligned correctly; if the identification result is different from the value of the signal to be aligned, the signal is failed to align the point.
The image recognition method for the remote signaling signal primitive is used for recognizing the color on the middle point, the vertical center line or the specific area of the primitive to judge the state of the remote signaling signal primitive. The specific identification logic is as follows:
and for the graphic elements of the circuit breaker in the remote signaling signal, a method for identifying the color of the central point is adopted.
