Description

Intelligent alarm system and method
Technical Field

Background
Although a warning board for prohibiting fishing is usually hung near a power line on a pond, an electric shock accident due to fishing may occur. The occurrence of accidents can be reduced by increasing the manual patrol frequency, but the manual patrol has the characteristics of high cost and poor timeliness. At present, video monitoring equipment is also installed at the side of a pond close to a power line by a power supply department door, monitoring pictures around the pond are transmitted to a monitoring center for remote viewing, but due to the fact that monitoring points are numerous, a video monitoring attendant stares at a screen to watch, and visual fatigue is easily caused, so that missed detection is caused. Therefore, manual patrol or remote staring on-duty watchmen are not an efficient solution.
Because in the video monitoring system near the pond of the power line, the monitoring depth of field, the illumination condition and the monitoring visual angle of the camera are not fixed, the detection precision of the intelligent video analysis system based on the general video image processing technology to the fishing behavior under the monitoring condition is not high.
Because the fishing rod is slender, when the target marking is carried out by using the target detection method based on the deep neural network, the sounding Box usually occupies most of the whole image, and therefore, the detection precision of the fishing rod is not very high.
Therefore, whether a general video image processing technology or a target detection technology based on a deep neural network is utilized, intelligent and automatic alarm for preventing electric shock in fishing is very difficult, the existing fishing electric shock prevention method and system are low in detection precision, a lot of misjudgments or missed judgments can be generated, and the method and system do not play a good alarm and prevention role in electric shock accidents possibly caused by fishing behaviors close to a power line.
