Embodiment 1
[0021] Please refer to figure 1 as shown, figure 1 It is a flowchart of a method for preventing misoperation of a substation based on image recognition provided by an embodiment of the present invention.
[0022] In this embodiment, the substation anti-misoperation operating system based on image recognition includes an image acquisition unit, an image processing unit, a substation monitoring system (with several measurement and control units), an anti-misoperation server, an anti-misoperation workstation and a network switch. The anti-misoperation method of substation based on image recognition specifically includes:
[0023] S101. The image acquisition unit collects static state and dynamic images of substation equipment, and sends the collected information to the image processing unit.
[0024] The image acquisition unit includes pan / tilt track image acquisition equipment and high-definition image acquisition equipment. Among them, the pan-tilt track camera collects the ...

The invention discloses a method for preventing misoperation of a substation based on image recognition, which is characterized in that the image acquisition unit acquires static and dynamic image information of substation equipment, which is converted into logic criteria by an image processing unit, and is connected with each interval equipment in the substation monitoring system The electrical quantity reflecting the opening and closing position of the equipment obtained by the measurement and control unit is combined to form a double-blocking criterion, which together serves as the control condition for switching operation sequence control or local operation, and realizes the image of the operated equipment (switch, knife switch) on the operation interface linkage. This method is applied to the substation anti-misoperation operating system based on image recognition, which avoids the problem of electrical misoperation caused by a single electrical logic lockout due to misjudgment errors and improper equipment operation, and effectively improves the safety and reliability of substation operations. It provides strong support for ensuring the safety and stable operation of the power grid.
Description
technical field [0001] The invention relates to the technical field of electric power operation control, in particular to a method for preventing misoperation of a substation based on image recognition. Background technique [0002] The substation is an important part of the power system, and it is responsible for important tasks such as voltage level conversion, input / removal of load, etc. Due to the large number of equipment such as circuit breakers, isolating switches, and grounding isolating switches in substations, if improperly operated, misoperation accidents are very likely to occur, resulting in large-scale power outages, equipment damage, and even casualties. In order to improve the safety of substation operation, microcomputer anti-misoperation operating system is widely used to prevent substation misoperation accidents. The system is mainly a computer key-operated anti-mistake system. Whether the anti-mistake locking mode is a separate five-proof system or an in...
