The acoustic-electric collaborative network focuses on the network coverage in the underwater scenes of the ocean, and is an important part of the integrated network of air, land, and sea. Compared with the radio link on the water, the underwater acoustic link has a low propagation speed, large transmission loss, and limited bandwidth, which is significantly different. Therefore, the design requirements of the acoustic-electric collaborative network routing method are: using the water radio network to assist the underwater acoustic network in information transmission. The advantage of semantic communication is that it is task-based, understands first and then transmits, which can greatly improve the transmission efficiency and reliability of the communication system. However, in the prior art, underwater semantic communication mainly focuses on the semantic acquisition and processing operations of the sender and the receiver, and ignores how the semantic information is transmitted more efficiently and energy-savingly in the network.

The specific acoustic-electric hybrid system may include more or fewer components than those shown in the figure, or combine certain components, or have a different arrangement of components.

[0066] In one embodiment, Figure 2 As shown, a method for information transmission is provided, which is applied to Figure 1 Take any transmission device in as an example to illustrate, including the following steps:

[0067] S101, when a transmission device meets a preset trigger condition, detecting whether a target device is a designated device and obtaining a detection result.

[0068] The transmission equipment includes underwater transmission equipment, surface transmission equipment and above-water transmission equipment. The preset trigger conditions include that the transmission equipment collects underwater environment information, or that the transmission equipment receives data to be transmitted sent by other transmission equipment. The designated device is a one-hop device or a two-hop device. The detection results include that the target device is a one-hop device, the target device is a two-hop device, and the target device is neither a one-hop device nor a two-hop device.

[0069] In an embodiment of the present application, the source device, relay device and target device can be determined in advance from the acoustic-electric hybrid system according to actual needs. Sensors can be installed in advance on the source transmission device, for example, cameras, sound sensors, temperature sensors, water quality detection sensors and other sensors can be installed. The layout information of each transmission device can also be stored in the local memory in advance, and the layout information includes the self-information of each transmission device, the routing information of the one-hop device and the routing information of the two-hop device.

[0070] When the transmission device is a source device, underwater environmental information can be collected through sensors. When the transmission device collects underwater environmental information, it can be determined that the transmission device meets the preset trigger conditions. When the transmission device is a relay device, when the transmission device receives data to be transmitted sent by other transmission devices, it can be determined that the transmission device meets the preset trigger conditions. When the current transmission device determines the target device information and meets the preset trigger conditions, it can obtain the layout information of each transmission device from the local memory, and then determine whether the target device is a one-hop device or a two-hop device of the current transmission device based on the layout information of the transmission device and the target device information.

[0071] S102, determining a preset transmission strategy according to the detection result, and transmitting the data to be transmitted to the target device according to the preset transmission strategy.

[0072] The preset transmission strategy includes preferably using a surface transmission device or an above-water transmission device to transmit the data to be transmitted. The preset transmission strategy can be determined by the location of each transmission device, the distance between each transmission device, and the attribute information of each transmission device. The preset transmission strategy includes the transmission device directly transmitting the data to be transmitted to the target device through a one-hop device or a two-hop device, or the transmission device transmitting the data to be transmitted to the target device through a transmission device other than the one-hop device or the two-hop device.

[0073] In an embodiment of the present application, after the current transmission device obtains the detection result based on the above steps, if the detection result indicates that the target device is a designated device, the current transmission device can directly transmit the data to be transmitted to the target device through a one-hop device or a two-hop device. If the detection result indicates that the target device is not a designated device, the current transmission device can transmit the data to be transmitted to the target device through a transmission device other than the one-hop device or the two-hop device. Optionally, during the data transmission process, in order to ensure the consistency of the data, the underwater transmission information can be packaged and processed to obtain a data packet, and then the data packet is used as the data to be transmitted and transmitted to the target device through a preset transmission strategy. For example, the underwater environmental information can be input into a semantic communication model pre-trained by a deep learning algorithm, and the semantic communication model is used to extract semantic information from the underwater environmental information, and then the semantic information is encapsulated into a data packet. After receiving the data packet, the target data can reconstruct the semantic information in the data packet to obtain the underwater environmental information.

[0074] The information transmission method provided in the embodiment of the present application detects whether the target device is a designated device when the transmission device meets the preset trigger condition, obtains the detection result, then determines the preset transmission strategy according to the detection result, and transmits the data to be transmitted to the target device according to the preset transmission strategy; the preset transmission strategy includes the preferred surface transmission device or the water transmission device to transmit the data to be transmitted. Among them, the designated device is a one-hop device or a two-hop device; the preset trigger condition includes that the transmission device collects underwater environmental information, or the transmission device receives the data to be transmitted sent by other transmission devices; the transmission device includes underwater transmission equipment, surface transmission equipment and water transmission equipment. In the above method, since the transmission efficiency of data on the water surface or on the water is higher than that under water, the surface transmission device or the water transmission device is preferred for data transmission, which can improve the forwarding participation of the surface transmission device or the water transmission device, transfer the overhead of the underwater hydroacoustic link to the water radio link, reduce the bit error rate, alleviate the congestion problem of the hydroacoustic network, and improve the data transmission efficiency, thereby realizing efficient underwater semantic communication, which has important applications in underwater exploration, marine scientific research, and underwater resource development.

[0075] In one embodiment, a specific implementation method for transmitting the data to be transmitted to the target device is also provided, such as Figure 3 As shown, in the above step, "determining a preset transmission strategy according to the detection result" includes:

[0076] S201, if the detection result indicates that the target device is a designated device, determine a preset transmission strategy to transmit the data to be transmitted to the target device according to the routing information of a one-hop device or the routing information of a two-hop device.

[0077] In the embodiment of the present application, if the current transmission device detects that the target device is a one-hop device or a two-hop device, the data to be transmitted can be transmitted to the target device according to the routing information of the one-hop device or the routing information of the two-hop device.

[0078] Specifically, Figure 4 As shown, the method may include:

[0079] S301: If the target device is a one-hop device, determine that the preset transmission strategy is to directly transmit the data to be transmitted to the target device.

[0080] S302: If the target device is a two-hop device, determine a preset transmission strategy to transmit the data to be transmitted to the target device via the transmission device and other transmission devices between the two-hop device.

[0082] In the embodiment of the present application, if the current transmission device detects that the target device is a one-hop device, the data to be transmitted is directly transmitted to the target device according to the routing information of the one-hop device. Specifically, the data to be transmitted can be unicast to the target device.

[0083] If the current transmission device detects that the target device is a two-hop device, the data to be transmitted is first transmitted to the next-hop device according to the routing information of the two-hop device, and then the data to be transmitted is transmitted to the target device through the next-hop device. Specifically, the data to be transmitted can be first unicast to the next-hop device, and then the next-hop device continues to unicast the data to be transmitted to the target device.

[0084] S202: If the detection result indicates that the target device is not the designated device, determine the preset transmission strategy as broadcasting the data to be transmitted to the candidate transmission devices, and transmitting the data to be transmitted to the target device through the candidate transmission devices.

[0085] Among them, the candidate transmission equipment is preferably surface transmission equipment or water transmission equipment.

[0086] In an embodiment of the present application, if the current transmission device detects that the target device is neither a one-hop device nor a two-hop device, the relay device between the current transmission device and the target device can be determined as a candidate transmission device. Specifically, the data to be transmitted can be broadcast to all other transmission devices in the acoustic-electric hybrid system, and other transmission devices that receive the data to be transmitted can be determined as candidate transmission devices, and then the data to be transmitted can be transmitted to the target device through the candidate transmission device. The information transmission method provided in the embodiment of the present application can directly unicast the data to be transmitted if the target device is a one-hop device or a two-hop device of the current transmission device, which can reduce the number of times the data to be transmitted is sent and received in the network, alleviate the number of collisions of the data to be transmitted, and improve the network throughput, thereby improving the efficiency of information transmission.

[0087] In one embodiment, a specific implementation method for transmitting the data to be transmitted to the target device through the candidate transmission device is also provided, such as Figure 5 As shown, the "transmitting the data to be transmitted to the target device through the candidate transmission device" in the above step S202 includes:

[0090] In the embodiment of the present application, the current transmission device can input the attribute information of each candidate transmission device into a preset algorithm for calculation, obtain a calculation result, and determine the priority of each candidate transmission device according to the calculation result. Optionally, the current transmission device can also input the attribute information of each candidate transmission device into a preset neural network model for prediction, and predict the priority of each candidate transmission device.

[0093] In an embodiment of the present application, after determining the priority of each candidate transmission device, the current transmission device can sort the priorities, then determine the candidate transmission device with the highest priority from the sorted candidate transmission devices, and finally transmit the data to be transmitted to the target device through the candidate transmission device with the highest priority. The information transmission method provided in the embodiment of the present application, because the level of priority can reflect the efficiency of data transmission of different lines, when the target device is not a designated device, forwarding the data to be transmitted through the candidate transmission device with the highest priority can improve the data transmission efficiency.

[0096] S502: Set the priority of all candidate transmission devices that belong to the underwater transmission device type to the second priority; the first priority is greater than the second priority.

[0097] Among them, the first priority is greater than the second priority, that is, the priority of the surface transmission equipment or the above-water transmission equipment is greater than the priority of the underwater transmission equipment.

[0098] In an embodiment of the present application, the current transmission device can read the layout information of each candidate transmission device from the local memory, extract the attribute information of each candidate transmission device, and then further determine whether each candidate transmission device belongs to an above-water transmission device or an underwater transmission device, and then set the priority of all candidate transmission devices that are above-water transmission devices to the first priority, and set the priority of all candidate transmission devices that are underwater transmission devices to the second priority.

[0099] Optional, such as Figure 7 As shown, if there are multiple candidate transmission devices belonging to the underwater transmission device type, the method further includes:

Based on this, the expectation factor of the water transmission equipment can be and forwarding delay Set to , , that is, the data is forwarded immediately without any delay.

[0103] (1)

[0104] (2)

[0105] in, is the communication radius of the underwater relay equipment, is the distance between the underwater relay device and the previous hop device, is the angle between the relay device and the previous hop device and between the previous hop device and the destination device. is the remaining energy of the current transmission equipment, is the initial energy of the current transmission device, The depth of the relay device, in units of , The role of is to normalize the depth so that it is . is a predefined threshold, represents the propagation speed of sound signals in water, is the communication radius of the underwater relay equipment, It is the distance between the underwater relay device and the previous hop device. The smaller the distance between the underwater relay device and the previous hop device The larger the value, the longer the forwarding delay. The purpose of the first term in formula (1) is to calculate the distance between the underwater relay device and the previous hop device. The larger the angle, the greater the angle between the relay device and the previous hop device and between the previous hop device and the destination device. The smaller it is, the easier it is to transmit the data packet closer to the destination device. The purpose of the second term in formula (2) is to make the relay device with more remaining energy have a higher priority, which helps to select the relay device with more remaining energy for forwarding, avoiding excessive use of a relay node and causing the node to fail. The purpose of the third term in formula (3) is to make the relay device with a smaller depth have a higher priority, which helps to help the underwater relay device forward the data packet to the relay device with a lower depth, thereby facilitating the search for surface devices and giving priority to surface devices for forwarding.

In the transmission process, the water transmission equipment is preferentially selected for forwarding, and the water radio link can bear part of the communication overhead for the hydroacoustic link. For the underwater transmission equipment, the priority is determined according to the expectation factor and / or the delay time. The smaller the expectation factor, the higher the forwarding priority and the shorter the delay time, which is conducive to selecting a relay device in good condition during the forwarding process. Moreover, when calculating the expectation factor, the distance, energy, depth and other information of the equipment are considered, which is conducive to selecting a device with a farther distance, more energy and closer to the surface equipment during the forwarding process, avoiding the failure of the equipment due to the exhaustion of the equipment energy, increasing the survival time of the network, making it easier for the underwater equipment to find the surface equipment, and increasing the forwarding participation of the surface equipment.
