The conventional marine ship communication is that the satellite is transmitted to the ground master station of the operator from the ship end in-service antenna station on the ship, and the satellite is transmitted to the ground master station of the operator for outgoing and returning, but in the process of data transmission, as the transmission distance from the ship end in-service antenna station to the satellite is far away, various different changes (such as strong convection weather, tsunami and the like) exist in the marine environment, in the process of transmitting data, the currently adopted single satellite narrow-band transmission mode is interfered in the process of transmitting data along with different marine environments, so that the phenomenon of data loss occurs in the satellite narrow-band transmission mode.
The embodiment provides a communication system based on satellite narrowband transmission and data self-adaptation, please refer to fig. 1, which comprises an environmental condition acquisition module 10, wherein the environmental condition acquisition module 10 is used for acquiring environmental data in a ship navigation range, generating network initial fluctuation data in the ship navigation range through the environmental data, an output end of the environmental condition acquisition module 10 is connected with a narrowband communication transmission unit 20, the narrowband communication transmission unit 20 controls the size of a data packet in a database when the data packet is transmitted from an end station to a satellite and a master station according to the network initial fluctuation data, the end station refers to a communication antenna arranged on the ship, the satellite is a communication satellite, the master station refers to an operator ground master station, then the environmental condition of a region (a position to be driven) between the ship and a position target is analyzed through the environmental condition acquisition module 10, and the network initial fluctuation data in the ship navigation range is generated through the environmental data, so that the network initial fluctuation data in the ship navigation range is generated through the environmental data, the narrowband communication transmission unit 20 is used for calling the network initial fluctuation data in the network initial fluctuation data, and the data packet is suitable for the initial fluctuation data packet to be transmitted from the network initial fluctuation data in the network environment, and the data packet is greatly lost in sequence from the master station to the initial fluctuation data station is reduced in the network fluctuation data transmission process;
when the ship is running and the narrowband communication transmission unit 20 is in the process of transmitting data, the data packet is affected by the actual environment, when the current network fluctuation condition is affected by additional intervention in the process of running, that is, the network initial fluctuation data increase means that the network is unstable, the current network fluctuation condition is recorded as network secondary fluctuation data, the output end of the narrowband communication transmission unit 20 is connected with the communication route switching module 30, and further, the communication route switching module 30 switches the narrowband communication route of the data packet transmitted by the narrowband communication transmission unit 20 according to the network secondary fluctuation data, the size of the data packet transmitted in the database is limited by the switched narrowband communication route, thereby improving the safety of the subsequent ship end station when transmitting the data packet to the satellite and the master station by the narrowband communication transmission unit 20, and reducing the phenomenon that the data packet is lost in offshore communication transmission.
The environmental data acquired by the environmental condition acquisition module 10 includes:
weather profile between the current location and the target location of the vessel;
a topography profile between the current position of the vessel and the target position;
the method comprises the steps of acquiring a magnetic field profile between a current position and a target position of a ship, determining network initial fluctuation data in a ship to-be-driven range by acquiring multiple environment profile to-be-driven position environments between the current position and the target position of the ship, wherein when the weather profile between the current position and the target position of the ship is acquired, the weather profile between the current position and the target position of the ship can be acquired through wireless connection with a weather station, the topography profile between the current position and the target position of the ship is acquired through satellite monitoring, and the magnetic field profile between the current position and the target position of the ship is acquired through a magnetic field positioning technology.
The narrowband communication transmission unit 20 includes a transmission decision module 201 and a multi-narrowband communication module 202, where the transmission decision module 201 is configured to determine a size of a transmission data packet according to network initial fluctuation data, and transmit the data packet to a satellite and a master station through the multi-narrowband communication module 202, so that the transmission decision module 201 determines to obtain the size of the data packet in the database according to the network initial fluctuation data, and transmit the data packet to the satellite and the master station through the multi-narrowband communication module 202, thereby reducing an environmental influence condition when the data packet is transmitted, improving stability when the data packet is transmitted, and reducing a situation that a packet is lost when the data packet is transmitted.
The size of the data packet in the database is determined by environment data in the following manner:
when the weather profile is bad: transmitting small data packets when rain, snow, wind, lightning or hail conditions occur;
when the weather profile is good: transmitting medium-sized data packets in the absence of rain, snow, wind, lightning or hail conditions;
when the topography profile is poor: transmitting small data packets when mountain bodies and rocks appear;
when the topography profile is good: transmitting medium-sized data packets when no mountain or rock exists;
transmitting small data packets when a range magnetic field exists;
and transmitting the medium-sized data packet when the range magnetic field is not available.
If the two profile differences and the range magnetic fields exist (e.g., rain, snow, or mountain, rock, or the range magnetic fields) at the same time, the multi-narrowband communication module 202 may be suspended from transmitting data to avoid a large loss of data, and then the small-sized data packet and the medium-sized data packet in the scheme are established according to the memory size of the data packet (e.g., the small-sized data packet may take a 5-8 value range and the medium-sized data packet may take a 8-10 value range).
Further, while the ship is in the process of running:
the influence of the environmental information in the vicinity of the ship is the network fluctuation condition of the current narrowband communication transmission unit 20 when transmitting data, the current network fluctuation is marked as network secondary fluctuation data, and the communication route switching module 30 switches the narrowband communication route of the data packet transmitted by the narrowband communication transmission unit 20 according to the network secondary fluctuation data, and enables the ship to perform communication transmission according to the switched narrowband communication route, wherein the specific environmental information of the ship passing position can be different in the process of the ship running, and further, the environmental information in the vicinity of the ship is suddenly encountered in the process of the ship running, such as strong convection weather, tornado and tsunami, through the environmental condition acquisition module 10, which is not usually generated, so when the environmental information appears, the communication route switching module 30 switches the narrowband communication route in the multi-narrowband communication module 202 to adapt to the narrowband communication route of the current environmental information to transmit the data packet, and the communication system can continuously transmit the data packet on the sea.
The multi-narrowband communication module 202 is illustrated in various communication transmission modes:
the multi-narrowband communication module 202 includes a regular narrowband communication route, an abnormal narrowband communication route, and a forbidden communication route, wherein:
in a normal state, the multi-narrowband communication module 202 transmits the data packet in a conventional narrowband communication route, in which case, in a normal case, the interference factor of the environmental data is small, that is, the data packet can be in a stable transmission interval when transmitted (a stable transmission interval is used for data, for example, 5-8 times, and the multi-narrowband communication module 202 performs communication transmission on the data packet in the conventional narrowband communication route at this time), so that the data packet can be transmitted in this case, and a measurement transmitted by the data packet is in a suitable interval, that is, a stable transmission interval;
when the communication route switching module 30 switches the normal narrowband communication route in the multi-narrowband communication module 202 to the abnormal narrowband communication route to transmit the data packet in the severe environment (the environment information is that some severe environments such as strong convection weather, tornadoes and tsunamis are suddenly encountered in the process of ship driving), the communication route switching module 30 switches the multi-narrowband communication module 202 to the abnormal narrowband communication route adaptively, and the capacity of the abnormal narrowband communication route capable of transmitting the data packet is smaller than that of the normal narrowband communication route (the capacity of the abnormal narrowband communication route capable of transmitting the data packet is smaller than 5, for example), so that the communication system can cope with some situations encountered in the offshore ship driving by limiting some data packets with smaller capacity to be transmitted in the abnormal narrowband communication route, so as to ensure continuous transmission of the data packet in the process of the offshore ship driving.
When the multi-narrowband communication module 202 is transmitting data packets and is subject to severe interference factors, the communication route switching module 30 switches the communication transmission route to a forbidden communication route, and when the forbidden communication route is started, the whole communication transmission system does not transmit the data packets any more, so that the data packets are prevented from being leaked in the transmission process.
Based on the scheme: when the communication route switching module 30 switches the communication transmission route of the multi-narrowband communication module 202, the data sequence module 203 is affected by the communication transmission route of the data packet transmitted by the multi-narrowband communication module 202 when the data sequence module 203 switches the communication transmission route of the data packet transmitted by the multi-narrowband communication module 202, and when the data packet is transmitted by the multi-narrowband communication module 202, the data sequence module 203 synchronously regulates the capacity of the preceding data packet to be the memory size, so that the multi-narrowband communication module 202 can acquire the capacity of the data packet in the database, which is convenient for the multi-narrowband communication module 202 to transmit the communication transmission route (for example, when the communication transmission route of the multi-narrowband communication module 202 is an abnormal narrowband communication route, the capacity of the data packet corresponding to the abnormal narrowband communication route is less than 5, and when the capacity of the data packet corresponding to the abnormal narrowband communication route is less than 5.
Extension of the expansion made in the process of data packet transmission:
the narrowband communication transmission unit 20 further includes a data sequence module 203, where the data sequence module 203 is configured to arrange data packets in a database according to a memory size, and adaptively arrange the data packets in the database according to the memory size of the data packets by the data sequence module 203, so that when the narrowband communication module 202 transmits data, the transmission decision module 201 can quickly acquire the size of the data packet adapted to environmental data, and the adaptation refers to the size of the data packet capable of enabling the data packet to be stably transmitted under the environmental data, for example: the environmental data is 5 (the environmental data 5 is established according to the environmental conditions in the scheme, for example, the environmental data is set to 5 when the weather is strong convection weather, tornado or tsunami, the data packet size is required to be less than 5 when the weather is strong convection weather, tornado or tsunami, the environmental data is set to 0 when the weather is strong convection weather, tornado or tsunami, and the data packet size can be greater than 5), and the data packet size is required to be less than 5, so that the loss condition of the data packet in the transmission process is reduced.
When the multi-narrowband communication module 202 arranges the data packets, the environmental information is affected by the environmental information nearby in the ship driving process, the environmental condition acquisition module 10 acquires the environmental information between the starting point and the target position when the ship is not driving, and in this process, the ship is not driving, so that in the ship driving process, the specific environmental information of the ship passing position will have a difference, and further, the environmental information nearby the ship in the ship driving process is acquired in real time through the environmental condition acquisition module 10 (the environmental information refers to that when some severe environments such as strong convection weather, tornado and tsunami are suddenly encountered in the ship driving process), and the arrangement sequence of the data packets in the database is regulated through the real-time environmental information nearby the ship: the data packets arranged in the database at the front are determined according to the environmental information near the ship, so that the transmission determination module 201 can select the size of the data packet matched with the current environmental information (the matching means that when the value of the environmental information is 6, the data packet with the size of the data packet at the front in the database is 6, so that the multi-narrowband communication module 202 can transmit).
The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above-described embodiments, and that the above-described embodiments and descriptions are only preferred embodiments of the present invention, and are not intended to limit the invention, and that various changes and modifications may be made therein without departing from the spirit and scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
