Due to the increasing maturity of wireless transmission technology, it has been widely used in many fields. The application of wireless transmission systems has effectively improved the efficiency and safety of some outdoor operations. Today we will learn about the important applications of wireless transmission in coal mining.
Due to the deep underground and complex environment, underground coal mine operations have a high rate of safety accidents. When encountering an emergency, traditional communication methods cannot transmit various information in a timely and effective manner. The multi-hop ad hoc network system adopts the Mesh ad hoc network mode, which has excellent performance such as automatic networking, automatic network healing, and decentralized network topology. It is very suitable for building a stable network in the complex environment of coal mining and providing wireless broadband access signals.
Introduction to design plan
In the underground tunnel, a multi-hop self-organizing network relay base station equipment is placed at intervals, and adjacent base stations can be directly interconnected to form a network. Based on the total length of a mine tunnel of 10 kilometers, only about 30 multi-hop ad-hoc network relay base stations need to be deployed to achieve full coverage of wireless broadband network signals in the entire underground working area.
The underground wireless broadband system composed of a multi-hop ad hoc network system has a large business capacity and can support more than 300 terminals to access the network at the same time. When underground personnel work, they carry handheld smart terminals with them, which can automatically connect to nearby multi-hop self-organizing network relay base stations, and then connect to the ground dispatching and command center through multi-hop relay links. Ground dispatch commanders and underground workers can exchange various data information, audio and video information, etc. in real time.
Multi-hop ad hoc network systems have strong self-healing capabilities. If any multi-hop ad-hoc network relay base station equipment is damaged or accidentally leaves the original network, the remaining relay base stations will automatically reorganize the network. That is to say, if any device in the group goes offline, the corresponding device will continue to communicate within the effective antenna coverage, ensuring that the network does not go offline. In practical applications, we can adopt a ring network design without worrying about ring network congestion.
Suntor Mesh self-organizing network equipment can adopt a variety of communication combination methods and be applied to different usage scenarios. It can be installed at fixed points or in places such as moving vehicles, ships, personnel, robots, drones, unmanned ships, etc. for rapid wireless deployment. The product software module integrates base station communication, client communication, point-to-point communication, and its own MESH self-organizing network communication function and automatic roaming function that are different from other mesh products on the market. Through the application of this system, in the coal mining process, it will help improve coal mine production efficiency, improve safety production conditions, and provide important technical support for coal mine safety production and dispatching communications.
