Analyze the important applications of Mesh ad hoc networks in coal mining

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.

Mesh wireless self-organizing network equipment has outstanding advantages in maritime emergency communication systems

With the increasing frequency of human maritime activities, the role of maritime emergency communication support in marine activities has become increasingly apparent, and the construction of its system has become the focus of attention of countries at home and abroad. The maritime environment is vast and changeable, and the security situation is complex. Various marine natural disasters and maritime emergencies bring serious harm to marine activities. Therefore, in order to ensure the safety of natural disasters and emergencies at sea. It is imperative to establish a complete maritime emergency communication system.     Due to the harsh natural environment of the ocean, the maritime emergency communication system must meet basic support requirements such as comprehensive coverage, key reinforcement, emergency dispatch, and rapid response. Different from land emergency communication support, maritime emergency communication support usually needs to face unfavorable conditions such as lack of basic communication facilities at sea and harsh offshore working conditions. Moreover, maritime emergencies usually have the characteristics of sudden incident, short emergency response window, and serious consequences. Therefore, the requirements for maritime emergency communication support are relatively high.         Restricted by the maritime natural environment, maritime communications are basically dominated by wireless communications. The diversity of maritime environments and maritime emergency scenarios determines that maritime emergency communications must include a variety of wireless communication methods. At present, maritime emergency communication systems mainly include maritime wireless communications, marine satellite communications and shore-based mobile communications, which together form a communications network that basically achieves full coverage of the ocean. The system can ensure daily ship-to-coast and ship-to-ship communications in offshore, distant seas and distant oceans; it provides relatively reliable, Accurate, timely and secure communications infrastructure.     The powerful Mesh wireless self-organizing network equipment is the core equipment of today's maritime emergency communication system. Maritime wireless emergency communications constructed from Mesh wireless ad hoc network equipment have the following advantages:     Centerless and fast networking: After the device is turned on, it will quickly search and discover other nearby devices. There is no need to perform network planning and configuration in advance, and the network will be automatically established. When other nodes are added to the existing network, the new equipment will be integrated with the original network into a larger network through direct connection or jump, so that the normal work of the entire network does not depend on any node.     Reliable network transmission: The frequency can be flexibly configured, so that the device can still ensure normal communication work and data services when facing a changeable, complex, and flexible environment. In actual use, if a node suffers an accident and causes service interruption, the network will reselect a link to continue transmitting data to ensure the normal operation of the service.     Easy to expand: New wireless autonomous network equipment can be directly connected to the original network; if a node is outside the network coverage, other nodes can also be used as relay points to allow the node to access the network.     Suntor has 13 years of application experience in the wireless transmission industry, and has jointly developed products with a master's and doctoral team from Northwestern Polytechnical University.

What factors will affect the COFDM devices in the transmssion process

COFDM is a very advanced technology in the field of wireless transmission. Its main function is to rapidly and stably transmit high-definition audio and video signals in a blocked mobile environment. Its biggest advantage is that it supports the application of breaking through the limit of visual distance. Therefore, it is widely used in the field of modern wireless transmission. But while COFDM is so powerful, there are a number of factors that affect the practical application of COFDM, which we will look at below. 1、Antenna gain   In the application of COFDM mobile wireless video transmission equipment, when the transmitter adopts high-gain directional antenna, the power density (field intensity) in the communication direction can be significantly improved; when the receiver adopts high-gain directional antenna, the signal/noise ratio can be significantly improved, and the receiving field intensity can be increased, thus greatly improving the communication distance.     2、Obstruction   COFDM mobile wireless video transmission equipment has the ability of diffraction, but the diffraction will cause the weakening of the transmission signal, so when the blockage is more dense, the transmission distance of the equipment will be closer.     3、Equipment power   Generally speaking, under certain transmission environment and conditions, the larger the power of COFDM mobile wireless video transmission equipment, the longer the transmission distance.     4、Same frequency electromagnetic signal interference   Although COFDM mobile wireless video transmission equipment has a very strong anti-interference ability, its transmission distance will be affected by the signal interference of the same frequency.     5、Altitude   Due to the radian of the earth, there will be a certain drop between the transmitting end and the receiving end of the equipment as the distance increases. Therefore, in the long-distance transmission process to adjust the corresponding position according to the altitude.

Wireless Mesh System for Mining

  Wireless Mesh System for Mining   Mining support systems are used extensively in mining due to the operational efficiencies they bring, allowing a mine site to operate with fewer personnel and with less idle time for planning or unexpected occurrences. However, providing mobile communications to support these systems in open pit mines pose significant challenges, due to the dynamic nature of mining areas, radio propagation due to mine topography and environmental constraints.   Mining operations are like moving cities; as the mining material is extracted, the mine sites change and grow. Hence, fixed communications networks are often not feasible alternative – the communication networks on mine sites need to be mobile and easily redeployed to suit the operating environment. Wireless LAN mesh networks fit mining requirements, due to their redundancy, scalability and ease of re-deployment. SUNTOR MESH, in particular, combines broadband data rates with cellular mobility, thus being a suitable choice for demanding mobile broadband users.   Mobile data communications based on the SUNTOR MESH wireless LAN mesh has been extensively proven and is widely adopted, both in Australia and overseas. The system is particularly suited to mining due to its ruggedness, resilience and survivability.   Other relevant features of the mesh are resistance to interference and fast route convergence, which are essential for low and deterministic latency.   The wireless mesh Ethernet networks can be designed to support a common radio infrastructure across the mine site for all the mining support systems. Traditionally, on-site communications staff were required to maintain many disparate communications technologies for each separate system supporting the mining function. Now a single site-wide network, based on Ethernet, can be used to support all the legacy data systems and allow expandability to future services. Sharing the communication infrastructure with operations functions, maintenance and other support systems such as environmental monitoring and safety systems means the investment on the wireless infrastructure can be fully realised over a number of different services.   Choosing a wireless mesh network means that although many mining systems are sharing the infrastructure, a single point of failure will not affect normal operations. The mesh networks allow for redundancy with overlapped coverage, adaptive mesh communications and multiple access points to cabled services in case of primary link failure. Utilising these features, networks can be planned to survive equipment outages with minimal impact on mining support systems.   The remote and mobile modems deployed in the network can allow connection of multiple IP addressable devices using standard Ethernet connectivity. This allows for devices that are not wirelessly enabled to function transparently on the wireless mesh network without the need for additional drivers. Serial devices can also be added to the network with serial modems designed for use with the mesh LAN or Ethernet serial device servers.   Contact us for further information.   Products in the project   ST9601MS and ST9602MD
