Intrusion early warning method, device and electronic device

Abstract

The invention provides an intrusion early warning method, an intrusion early warning device and an electronic device. The method includes the following steps that: whether an abnormal target exists ina specified area is determined according to a video frame image; if the abnormal target exists in the specified area, the target information of the abnormal target is determined, wherein the target information comprises one or a plurality of kinds of information selected from target category, target position, target size, target speed, and target trajectory; an early warning grade corresponding to the target information is generated with a pre-trained graded early warning model, wherein the graded early warning model is a deep neural network model; and early warning is performed according tothe early warning grade. With the intrusion early warning method, the intrusion early warning device and the electronic device of the invention adopted, the information of an intruding object can be better determined; graded warning is performed based on the information of the intruding object; and therefore, relevant personnel can be assisted to take targeted measures to further ensure the security of railway operation.

Description

technical field [0001] The invention relates to the field of security technology, in particular to an intrusion early warning method, device and electronic equipment. Background technique [0002] With the continuous increase in the operating mileage of high-speed railways and the gradual increase in vehicle speed, the safety of high-speed railway operations has become a major issue related to the national economy and people's livelihood. However, in road sections such as mountainous areas and tunnel entrances, there is the possibility of sudden rockfall and debris flow, and machinery, personnel, and construction materials often intrude into the existing line boundaries in road sections under construction, which seriously affect the safety of high-speed railway traffic. Due to the high speed of the train, it is difficult to ensure the safety of the train by relying on the driver's vision and traditional detection methods to identify foreign objects. The foreign matter invas...

Problems solved by technology

[0003] To this end, countries around the world have studied various railway perimeter intrusion monitoring methods such as infrared, ultrasonic, and laser, but the existing methods only detect the presence of intruders (also known as abnormal targets) in
