China is a large sea country with a vast sea area. The sea environment is complex and changeable, which determines that offshore operations are high-risk accidents. In order to maintain the safety and stability of offshore operations, increase the ability to respond to emergencies and the ability to dispose of them. It is imperative for the marine regulatory authorities to construct an early warning and search and rescue command communication platform for offshore operations. Affected by the working environment at sea, wireless emergency communication is generally adopted to achieve early warning and search and rescue operations at sea.
The marine emergency communication system mainly includes maritime wireless communication, marine satellite communication and shore-based mobile communication, which together constitute a communication network that basically realizes full coverage of the ocean. The system can guarantee the daily communication of ships, coasts and ships-ships in the offshore, offshore and oceanic regions; it is relatively reliable in the fields of marine transportation, oil and gas exploration and exploitation, marine environmental monitoring, marine fisheries, marine aquaculture and marine scientific research. Accurate, timely and secure communication infrastructure.
The maritime wireless emergency communication constructed by Mesh wireless ad hoc network equipment has the following advantages:
Centerless fast networking: After the device is powered on, it will quickly search for and discover other devices in the vicinity, without the need for network planning and configuration in advance, and automatically set up the network. When other nodes join the existing one, the new device will merge 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 guarantee normal communication work and data services in the face of a changing, complex and flexible environment. In the actual use process, if the node is accidentally caused by the service interruption, the network will re-select a link to continue to transmit data to ensure the normal operation of the service.
Easy to expand: The new wireless autonomous network device can directly access the original network; if a node is outside the network coverage, it can also use other nodes as a relay point to let the node access the network.
The high-power self-organizing network equipment independently designed and developed by Tengyuan Zhituo can adopt various communication combinations and be applied to different usage scenarios. The transmission power is 1-3W and the distance can reach more than 5km. In overclocking mode, the bandwidth will reach 315Mbps, and in normal mode, it can reach 280Mbps, and we can also customize the frequency drift according to user needs. For example, the conventional frequency is 5500, 5540MHz, etc. We can make the frequency from 5504, 5544 according to the needs of customers. Start, let the frequency drift 4MHz with the normal frequency.
Maritime emergency communications, with its many advantages, can often be applied in the following scenarios.
1. Multiple ships moving in wireless communication
When multiple vessels work together to complete a job, it is often necessary to establish a wireless broadband network to enable networking, intercommunication of voice, video, and data. Tengyuan Zhituo's maritime emergency communication system, which is built by Mesh wireless self-organizing network equipment, solves the following technical problems of communication in the queue of ships with its unique characteristics of self-organizing network and self-healing.
(1) Network omnidirectional high-bandwidth: use high-gain antennas to ensure omnidirectional bandwidth under constant conditions of relative position of the vehicle;
(2) Fully self-organizing network: no need to set network center points or relay points, the equipment only needs to be powered on, and automatically forms a network;
(3) Strong self-healing ability of the network: some individuals are out of the connection range during the process, and when the scope is re-entered, the connection is automatically established;
(4) The network topology can be arbitrarily deformed and folded: the connection of the entire network is not affected by the relative positional movement of the relay point, and can be arbitrarily deformed and folded;
2. Maritime supervision wireless communication
Through the maritime emergency communication system established by Mesh wireless self-organizing network equipment, the national maritime department can conduct maritime safety supervision and placement of ship pollution, ship and offshore facility inspection, and maritime security management; the fishery administration department undertakes national marine surveillance and fishery administration. The fishing vessel fishing port supervision and fishing vessel inspection work shall be responsible for cruise surveillance, supervision and management of the jurisdictional waters, investigate and deal with illegal activities in accordance with the law, and safeguard the national marine and fishery rights and interests.
3, marine breeding wireless monitoring
Due to the high economic value of seafood, seafarers often have stolen. The maritime emergency communication system built by Tengyuan Zhituo Mesh wireless self-organizing network equipment can establish a simple, fast and efficient monitoring system to improve the whole breeding. Regional security and prevention, while reducing operating time and labor time, and greatly saving costs.
The maritime wireless emergency communication system is an important guarantee for ensuring the safety of offshore operations. There will be a wider range of applications in various future marine activity projects. Want to know more about maritime wireless communication knowledge, you can pay attention to Tengyuan Zhituo.
