The embodiment of the invention discloses a method,device and system for alarming existence of people in a hazardous area during bracket movement, and relates to the technical field of coal mine safety. The method comprises the following steps ofacquiring a real-time video image in a hydraulic bracket area; recognizing and tracing the lifting state of a supporting column in the video image and thebracket moving condition of the hydraulic bracket, and determining the hazardous area according to the descending supporting column when it is determined thatthe descending supporting column exists;sending out pre-warning information when workers exist in the hazardous area; and recognizing and judging the forward moving condition of the hydraulic bracket when no staff is available in the hazardous area, determining the hazardous area according to the forward moving hydraulic bracket when the forward moving hydraulic bracket exists, generating alarm information when the workers exist in thehazardous area, and sending out the alarm information. The method,device and system for alarming existence of people can solve the problem of safety accidents caused by the fact that the safety reminding modes to the workers are affected by many uncertain factors when an existing hydraulic bracket is moved.
Description
technical field [0001] The embodiment of the present invention relates to the technical field of coal mine safety, in particular to an alarm method, device and system for people in a dangerous area when a rack is moved. Background technique [0002] The coal mine fully mechanized mining face is the first production site of underground coal, and the hydraulic support is the support equipment for the coal mine fully mechanized mining face. The hydraulic support supports the roof of the working face to ensure the safety of the working space. The hydraulic support is composed of top beam, base, supporting column, jack and other components, and is connected with the scraper conveyor of the working face through the jack to realize the equipment matching of mining, transportation and supporting in the fully mechanized mining face. The moving of the hydraulic support means that after the coal mining of the fully mechanized mining face, the hydraulic support moves forward through man...
