Mine safety information collaborative awareness and disaster real-time pre-warning system

Abstract

The invention provides a mine safety information collaborative awareness and disaster real-time pre-warning system. The system comprises an information centre monitoring platform, wherein the information centre monitoring platform is connected with a Beidou satellite wireless communication unit; the Beidou satellite wireless communication unit is connected with an underground optical fiber ring network communication unit; the underground optical fiber ring network communication unit is connected with a bottom layer wireless network communication unit; the bottom layer wireless network communication unit is connected with an underground multi-variant heterogeneous information acquisition control unit; and the underground multi-variant heterogeneous information acquisition control unit is connected with a basic information unit. According to the invention, the mine safety information collaborative awareness and disaster real-time pre-warning system is constructed by utilizing the Beidou satellite wireless communication unit which takes a Beidou satellite as a transmission core, so that multi-source heterogeneous information in a mine Internet of things information system are fused mutually; the unification of real-time monitoring, the network transmission, the dynamic identification and a feedback control technology is realized; and the dynamic reliability of a mine safety control strategy is improved effectively.

Description

technical field [0001] The invention relates to an early warning system, in particular to an early warning system capable of providing mine safety information monitoring and disaster prevention and control. Background technique [0002] my country is rich in coal resources and coal is the main energy source in my country. At present, coal accounts for about 73% of my country's energy production and consumption. Due to the complex coal storage conditions in our country, the low level of coal mine automation, the large number of underground workers, the relatively backward technology used in the production safety monitoring system, single function, and management and other factors, the production cost is high and the safety situation is not optimistic. The death toll of coal mine accidents in the country remains high, and the death rate per million tons is much higher than the average level of the world's major coal-producing countries, seriously affecting the sustainable deve...

Problems solved by technology

Although the state has promulgated relevant regulations on the construction of the six major systems, in actual operation, the current construction of the emergency avoidance system is relatively independent, and has not been combined with existing security systems such as monitoring and monitoring, personnel positioning, and self-rescue under pressure.

There is heterogeneity in the network structure and data types among the various subsystems. At the same time, due to the different manufacturers and system construction periods of the existing safety production monitoring and monitoring system, there is no unified communication protocol and access technology between the various systems. The data structure between the systems is very different, showing multi-source and heterogeneity
