Abstract

The embodiment of the invention discloses a heterogeneous network communication system for a coal mining face of a coal mine, and relates to the technical field of underground communication of coal mines. The system comprises terminal equipment, a base station and gateway equipment, and the terminal equipment comprises a wireless communication module which comprises an LIFI module and a WIFI module; the terminal equipment is used for automatically switching a wireless transmission mode according to the signal intensity; the base station at least comprises an LIFI module and a WIFI module, which are respectively used for realizing bidirectional wireless transmission communication of data information; and the gateway equipment is used for converting the current node information of the uplinkor the downlink into identifiable information of the next node equipment and sending the identifiable information to the next node equipment. The device can break through the restriction of the traditional radio communication technology, is compatible with different types of network types, and provides a high-speed and reliable underlying data communication link for building application scenes such as a coal mine intelligent industrial Internet platform, a coal mine big data platform and a mine comprehensive management and control platform.

Description

technical field [0001] The invention relates to the technical field of underground communication in coal mines, in particular to a heterogeneous network communication system for a coal mining face in a coal mine. Background technique [0002] Coal is the main energy source in our country, and it will still be an important foundation to support the economic development of our country for a long time. The construction of my country's smart mines has entered the initial stage. Intelligence will be the main theme of the future development of my country's coal mines. As one of the most important systems in coal mine production, communication will directly affect the overall benefits of coal mine enterprises. [0003] The communication system is an important cornerstone for data-driven intelligent coal mining. Intelligent application scenarios such as personnel positioning in coal mines and unmanned vehicles and other moving targets, unmanned inspection of chambers, underground e...
