Voice alarm system for underground coal mine inclined drift travelling crane and pedestrian

Abstract

The invention discloses a voice alarm system for underground coal mine inclined drift travelling crane and pedestrian. A personnel positioning substation is used for receiving personnel positioning card information read by a personnel positioning card reader, meanwhile receiving winch start-stop state transmitted by a winch start-stop sensor, and uploading the state to an upper computer through an industrial Ethernet switch in real time; a data conversion module is used for receiving commands transmitted by the upper computer through the industrial Ethernet switch; a sound power amplification module is used for outputting voice in a sound mode through a loudspeaker; the upper computer is used for sending commands of the personnel positioning card information read by the personnel positioning card reader through the industrial Ethernet switch, storing detailed information of intrude personnel, and transmitting alarm information broadcasted after processing to a data conversion module of a voice broadcasting system through the industrial Ethernet switch. The system prevents personnel from intruding an inclined drift travelling crane zone by mistake, and the upper computer on the ground displays pedestrian information during travelling, and warns staffs not to intrude the zone during travelling, so that the intrinsic safety of inclined drift transportation is realized.

Description

technical field [0001] The invention belongs to the technical field of auxiliary transportation in mines, and in particular relates to a voice alarm system for driving and pedestrians in inclined lanes in coal mines. Background technique [0002] In the underground transportation of coal mines, inclined lane transportation is common. Among all kinds of coal mine safety accidents in the country, safety accidents during inclined lane transportation account for a large proportion. . When the winch is driving, people should be prevented from breaking in and causing safety accidents. Because the winch is in the process of lifting the inclined lane, it is very easy for the lifting vehicles and objects to fall off. If there are vehicles and people walking together, due to the narrow laneway, scraping accidents are likely to occur, which seriously threatens the safety of pedestrians and may cause casualties. Therefore, the inclined lane Transportation must prevent vehicles and peo...

Problems solved by technology

Because the winch is in the process of lifting the inclined lane, it is very easy for the lifting vehicles and objects to fall off. If there are vehicles and people walking together, due to the narrow laneway, scraping accidents are likely to occur, which seriously threatens the safety of pedestrians and may cause casualties. Therefore, the inclined lane Transportation must prevent vehicles and people from traveling together

At present, the commonly used lanyard interception mainly relies on pedestrians' self-consciousness, and does not have the functions of personnel targeting and recording of intruders and violators, and no effective measures have been taken in terms of technical achievements
