Description
Technical Field
The invention relates to the field of video monitoring and machine vision, in particular to an electronic police device for violation of regulations of underground personnel in a coal mine.
Background
Along with the increase of energy demand and the improvement of coal mining mechanization degree, underground coal mining gradually extends to deeper underground along with the progress of technical equipment, the mining level is more efficient, and the waste coal seam can be mined again. The video and personnel integrated monitoring system is one of indispensable important systems in a coal mine integrated automatic system as an objective, mature and stable safety monitoring means, and plays an important role in safety production under a coal mine.
Traditional video monitoring utilizes the camera to be in the regional arrangement of colliery focus in pit, can only play and record the scene image in real time at display terminal, has video retrieval and shows historical image's function, because the very big manpower-dependent of video monitoring system continuously observes and judges, needs the long-time content of being absorbed in the video picture of monitoring personnel, leads to the reduction of work efficiency and validity very easily.
With the wide application of coal mine video monitoring, the video image analysis technology is fully utilized in an underground production business system, and particularly relates to areas such as a coal mine safety production fully-mechanized coal mining face, a transmission system, a water pump room and the like. The mine video monitoring system has the advantages that the full coverage of the mine camera is realized, the number of monitoring pictures is increased, the monitoring difficulty is increased, the requirement of coal mine safety production cannot be gradually met by adopting the traditional manual monitoring method, and along with the development of a machine vision technology, the mine video monitoring system is more important for adding an auxiliary alarm system based on a moving target detection technology.
Although emerging technologies such as internet of things and artificial intelligence are developed rapidly in recent years and monitoring videos can be analyzed on a cloud computing platform to identify people, objects and even behaviors, the technologies all have to use a large amount of network bandwidth resources to transmit videos to a cloud computing center for processing, and the processing mode has the following problems: (1) the traditional video monitoring technology only can play a role in monitoring a monitored object, and when personnel in a monitored area violate rules and equipment faults, early warning can not be timely carried out on personnel and emergency treatment can not be timely carried out on equipment, so that a delay phenomenon can be caused; (2) under the complex condition, the recognition and analysis of the target by monitoring cannot be clear and complete, and the phenomenon of misjudgment is easily caused. When the underground coal mine production is carried out, although video monitoring is distributed in a plurality of key places, the video signals are generally only used for monitoring and cannot capture audio signals, due to the fact that underground dust is large, when a lens is polluted, a picture cannot be clearly captured, clear videos can be uploaded, effective early warning and prevention behaviors cannot be carried out on underground workers, and therefore the monitoring workers often have no strategy when processing some underground video information. Therefore, the electronic police device for the coal mine underground personnel violation is designed, the interference of dust can be effectively avoided, the pictures and the audio can be captured in time when the underground equipment is abnormal and the personnel violate behaviors, the early warning processing is carried out, and the electronic police device has great strategic significance on the safety guarantee of coal mine safety production and the personnel.
