Mining wireless frequency-mixing multidata monitoring system

Abstract

The invention discloses a mining wireless frequency-mixing multidata monitoring system, which comprises a ground surface part and an underground part; the ground surface part comprises a monitoring hose, a wireless receiver, a monitor and an alarm; the underground part comprises a wireless portable multidata acquisition instrument, an environment parameter sensor, a vital sign parameter sensor, a wireless relay, a video acquisition device and the like; the wireless portable multidata acquisition instrument is adaptively connected with the environment parameter sensor and the vital sign parameter sensor to form a front-mounted acquisition group; and acquired underground environment information and vital sign information of rescue workers are transmitted to the monitoring host of the ground surface part through the wireless relay and the wireless receiver so as to carry out concentrated analysis and processing. The mining wireless frequency-mixing multidata monitoring system is simple and feasible, lightweight and easy to carry, can be carried underground by the rescue workers, is capable of rapidly establishing a wireless ad hoc network in a short time and transmitting the underground environment data, image data and vital sign data of the rescue workers to the ground command center and realizes safety monitoring to underground environment and personnel.

Description

technical field [0001] The invention relates to the technical field of mine monitoring, in particular to a mine-used wireless frequency mixing multi-data monitoring system. Background technique [0002] At present, my country's coal mine safety production situation is very severe. With the continuous extension of mining depth, the gas content of coal seams in various coal mines is on the rise, and some low-gas mines extend to high-gas areas. As a result, the contradiction between high production and high efficiency of mines and high gas emission is becoming more and more prominent, and gas accidents have become an impact. Major accidents in coal mine production safety. [0003] In mines containing explosive gases such as methane, safety issues are the top priority. The environment in mines is complex and changeable, and it is necessary to detect various environments. At present, most of the environmental monitoring instruments in mines can only monitor a single type. Envir...

Problems solved by technology

[0003] In mines containing explosive gases such as methane, safety issues are the top priority. The environment in mines is complex and changeable, and it is necessary to detect various environments. At present, most of the environmental monitoring instruments in mines can only monitor a single type. Environmental parameters, can not monitor a variety of environmental parameters, and transmit data through cables, which greatly restricts the placement area of ​​monitoring instruments, and these monitoring instruments cannot monitor the vital signs parameters of rescuers; Coal mine safety and production management and rescue work cause potential danger, and the underground environment cannot be comprehensively analyzed and scientifically judged to ensure the smooth progress of coal mine rescue work
