Technical Field
The invention belongs to the technical field of power measurement, and particularly relates to a management and detection system and method for an operation state of a switch cabinet and computer equipment.
Background
At present, the normal operation of a high-voltage switch cabinet is an important part in the power industry, and the operation state of the switch cabinet is generally determined by a plurality of equipment terminals to achieve multiple times of confirmation so as to ensure the absolute correctness of the operation state of the switch cabinet. Therefore, the operation state of most switch cabinets can be confirmed by two different methods of sensors and video image monitoring. Most of common video image-based monitoring methods have relatively strict requirements on the installation angle of a camera or illumination conditions, and some methods need additional calibration work. Therefore, in the prior art, each machine needs to be calibrated, the installation complexity is high, and the installation is inconvenient for users.
Through the above analysis, the problems and defects of the prior art are as follows: the requirements for the installation angle, the light and the like of the camera in the prior art are strict, some cameras even need to be calibrated, the installation complexity is high, and the installation by a user is inconvenient.
The difficulty in solving the above problems and defects is:
(1) the switch cabinets of different manufacturers have different structures, and a proper method is needed to enable the switch cabinets to be universal and switch cabinet equipment with different structures; (2) the circuit breaker in the switch cabinet is relatively complex in structure, the cameras are relatively troublesome to install, and the consistency of the content of pictures shot by each camera is difficult to ensure; (3) the circuit breaker and the grounding switch in the switch cabinet are in a closed state, and the light is poor; (4) the switching between the test position and the working position of the circuit breaker usually needs a process of traveling by 200mm, but the test position or the working position is not necessarily accurately in place every time, usually, a certain error exists, and the circuit breaker is basically normal within +/-2 mm, so that the state judgment of the circuit breaker preferably needs to be combined with a ranging result.
The significance of solving the problems and the defects is as follows: the method with universal universality is needed, effective and accurate identification can be achieved for switch cabinets produced by different manufacturers, the requirement on camera installation is low, the method can be better adapted to different angles of a camera, identification can be completed under the condition of poor light, the actual travelling mileage of a circuit breaker can be accurately measured, the method is very critical to the popularization of a scheme for confirming the state of the switch cabinet images, the complexity of installation is greatly reduced, the workload of a user is reduced, the current state of the switch cabinet and the travelling process of the circuit breaker can be effectively prompted to the user in real time, and the method is very important reference information for the user.
