[0004] However, the timeframe for data transmission from seabed observation nodes to shore-based platforms is random. When multiple seabed observation nodes transmit data simultaneously, the signals from these nodes overlap. The shore-based platform struggles to separate these overlapping signals, leading to an increased bit error rate. Summary of the Invention

Furthermore, the communication window allocated by the base station for the seabed observation node is acquired from the base station, and it is determined whether the current first timestamp is within the communication window. If so, the underwater sampling data is reported to the base station within the communication window. Therefore, the communication window for the seabed observation node to send data to the base station is allocated by the base station for that seabed observation node, and is not randomly assigned, effectively avoiding signal superposition caused by multiple seabed observation nodes simultaneously sending data to the base station, thereby reducing the signal error rate.

[0063] To address the technical problem of increased bit error rate in signals from seabed observation nodes in existing technologies, this application provides an underwater data reporting device that can reduce the bit error rate of signals from seabed observation nodes.
[0064] Figure 1 This is a flowchart illustrating an underwater data reporting method provided in an embodiment of this application. In one embodiment, the method is applied to a seabed observation node, and the method includes:
[0065] S1. Receive time information from the base station.
[0066] The time information of the base station is the local timestamp of the base station at the current moment.
[0067] S2. Adjust the local time of the seabed observation node according to the time information.
[0068] The local time of the seabed observation node is adjusted according to the local timestamp of the base station at the current moment, so that the local time of the base station is synchronized with the local time of the seabed observation node.
[0069] S3. Acquire underwater sampling data.
[0070] The underwater sampling data includes, but is not limited to, seawater temperature, salinity, pressure, dissolved oxygen, turbidity, and acoustic background. The seabed observation node is equipped with multiple sensor interfaces for data acquisition and sampling.
[0071] S4. Get the current first timestamp based on local time.
[0072] The current timestamp is the timestamp of the seabed observation node at the current moment.
[0073] S5. Obtain the communication window allocated by the base station to the seabed observation node from the base station.
[0074] It should be noted that the base station allocates a communication window for each seabed observation node. This communication window is used for data communication between the seabed observation node and the base station. The communication window is a preset time period. For example, if the preset time window for seabed observation node A is from 9 AM to 10 AM, then seabed observation node A can communicate with the base station during this time period. During other time periods, seabed observation node A cannot communicate with the base station.
[0075] It should be noted that there is no fixed execution order for S3-S5. For example, in this embodiment, S4 may be executed first, followed by S3. This application does not impose any restrictions on this.
[0076] S6. Determine if the current first timestamp is within the communication window. If yes, proceed to S7; otherwise, proceed to S8.
[0077] For example, if the communication window is from 9 AM to 10 AM, and the current first timestamp is 9:05 AM, then the current first timestamp is within the communication window. If the first timestamp is 10:06 AM, then the current first timestamp is outside the communication window.
[0078] S7. Report underwater sampling data to the base station within the communication window.
[0079] Within the communication window, the seabed observation node reports underwater sampling data to the base station.
[0080] S8, the seabed observation node has entered sleep mode.
[0081] When the current timestamp is not within the communication window, the seabed observation node enters a low-power standby state or sleep mode to reduce energy consumption.
[0082] This application provides an underwater data reporting method. The method includes: receiving time information from a base station; adjusting the local time of a seabed observation node according to the time information; acquiring underwater sampling data; obtaining a current first timestamp based on the local time, the current first timestamp being the current timestamp of the seabed observation node; obtaining a communication window allocated by the base station for the seabed observation node from the base station; determining whether the current first timestamp is within the communication window; and if so, reporting the underwater sampling data to the base station within the communication window. Thus, this application receives time information from a base station and calibrates the local time. Next, the current first timestamp is obtained. Furthermore, the communication window allocated by the base station for the seabed observation node is obtained from the base station, and it is determined whether the current first timestamp is within the communication window. If so, the underwater sampling data is reported to the base station within the communication window. Therefore, the communication window for the seabed observation node to send data to the base station is allocated by the base station for that seabed observation node, and is not randomly allocated, effectively avoiding signal superposition caused by multiple seabed observation nodes simultaneously sending data to the base station, thereby reducing the signal error rate.
[0083] Please see Figure 2 , Figure 2 This is a schematic diagram illustrating a process for acquiring underwater sampling data, provided as an embodiment of this application. In one embodiment, acquiring underwater sampling data includes:
[0084] S31, Receive data collection signaling from the base station.
[0085] The data acquisition signaling includes the sampling data type and the sampling period. The sampling data type indicates which type of data the seabed observation node is acquiring. The sampling period indicates how often the seabed observation node performs data acquisition operations.
[0086] S32. Collect underwater data according to the sampling period to obtain the first collection data.
[0087] For example, if the sampling period is one week, the seabed observation node will perform a sampling operation once every week. The first data collected includes, but is not limited to, seawater temperature, salinity, pressure, dissolved oxygen, turbidity, and acoustic background.
[0088] S33. Preprocess the first collected data to obtain the second collected data.
[0089] Data acquired by seabed observation nodes through sensor interfaces often contains noise. Therefore, preprocessing is required for the initial data acquisition. This preprocessing includes, but is not limited to, noise removal, mean filtering, and edge detection.
[0090] S34. Obtain the current second timestamp and the identifier of the seabed observation node.
[0091] Each seabed observation node has a unique identifier. This identifier is used to indicate the seabed observation node. The current second timestamp is the current timestamp of the seabed observation node. The current second timestamp is used to indicate the acquisition time of the first collected data.
[0092] S35. Generate underwater sampling data based on the current second timestamp, identifier, and second acquisition data.
[0093] This application embodiment generates underwater sampling data by adding a current second timestamp and the identifier of the seabed observation node to the second collected data. When the base station analyzes the underwater sampling data, it can filter out multiple underwater sampling data with the same or similar timestamps from multiple underwater sampling data reported by multiple seabed observation nodes based on the current second timestamp, thereby enabling the base station to conduct long-term, continuous, and real-time observations of the sea area.
[0094] In one embodiment, the seabed observation node compresses and encodes the collected underwater sampling data and stores it locally. When the seabed observation node receives a data reporting command from the base station or when its communication window is reached, the seabed observation node reports the locally stored underwater sampling data to the base station. The compression encoding includes, but is not limited to, differential encoding and variable-length encoding. The compressed underwater sampling data has a reduced data size, making it more suitable for low-bandwidth underwater data transmission.
[0095] In one embodiment, reporting the underwater sampling data to the base station within the communication window includes:
[0096] S71. Divide the underwater sampling data into multiple data packets.
[0097] This application's embodiments divide underwater sampling data into multiple data packets according to a preset data packet size. The preset data packet size was obtained by the applicant based on experimental data. For example, the preset data packet size can be 1500 bytes. Of course, the preset data packet size can be any other non-zero positive integer. This application does not impose any limitations on this.
[0098] S72. Send multiple data packets to the base station sequentially within the communication window.
[0099] The seabed observation node sends multiple data packets to the base station within the communication window.
[0100] In one embodiment, the plurality of data packets includes a target data packet, and the method further includes:
[0101] a. Receive multiple acknowledgment packets from the base station.
[0102] Each acknowledgment packet corresponds one-to-one with a data packet. These acknowledgment packets are used by the base station to confirm the data packets corresponding to them.
[0103] It should be noted that for each data packet received, the base station sends an acknowledgment packet to the seabed observation node.
[0104] In one embodiment, the plurality of data packets include a target data packet, and the method further includes:
[0105] Determine whether the base station needs to retransmit the target data packet according to the preset retransmission strategy; if so, send the target data packet to the base station.
[0106] It should be noted that when a seabed observation node does not receive an acknowledgment packet from the base station for a target data packet, the seabed observation node retransmits the target data packet to the base station according to a preset retransmission strategy. This preset retransmission strategy indicates whether the seabed observation node needs to retransmit the target data packet after not receiving an acknowledgment packet from the base station. For example, the preset retransmission strategy can be a maximum retransmission count of a preset value. When the maximum retransmission count is 3, it means that the seabed observation node has a maximum of 3 opportunities to retransmit the target data packet to the base station. If the seabed observation node does not receive an acknowledgment packet for the target data packet after sending it three times, the seabed observation node loses contact with the base station, requiring manual intervention or retransmission of the underwater sampling data in the next communication window.
[0107] In one embodiment, when a seabed observation node automatically detects an abnormal state, it records the abnormal state and reports the abnormal state information to the base station when appropriate. The abnormal state includes, but is not limited to, communication failure, data loss, and buffer overflow.
[0108] In one embodiment, the base station can periodically send diagnostic commands to the seabed observation node to trigger the seabed observation node to perform a self-check operation.
[0109] In one embodiment, the underwater sampling data includes multiple types of underwater sampling data, and the method further includes:
[0110] A. Receive data priority signaling from the base station.
[0111] Among them, the data priority instruction is used to instruct seabed observation nodes which data types to report first.
[0112] B. Determine the target underwater sampling data from multiple types of underwater sampling data based on data priority signaling.
[0113] The seabed observation nodes are capable of collecting various types of underwater sampling data. In scenarios where the underwater acoustic channel is congested, the seabed observation nodes can prioritize the transmission of underwater sampling data of higher importance based on data priority signaling.
[0114] C. Report the target underwater sampling data to the base station within the communication window.
[0115] It should be noted that step C is the same as or similar to S7. Therefore, this application will not elaborate further.
[0116] Please see Figure 3a , Figure 3a This is a schematic flowchart of an underwater data receiving method provided in an embodiment of this application. In one embodiment, the method includes:
[0117] S301. Query the working status of multiple seabed observation nodes.
[0118] The operational status of seabed observation nodes includes online and offline states. Online status indicates that the seabed observation node and the base station can communicate normally. Offline status indicates that the base station and the seabed observation node have lost contact and cannot communicate normally.
[0119] The base station can send a heartbeat signal to each seabed observation node to detect whether the node is online. If the seabed observation node is online, it sends an acknowledgment signal to the base station in response to the heartbeat signal, informing the base station of its current online status.
[0120] S302. Assign a communication window to each of the multiple seabed observation nodes according to the working status and preset working cycle.
[0121] The preset working cycle is the base station's working cycle, used for periodic data communication between the base station and multiple seabed observation nodes. The preset working cycle is set by the applicant based on actual conditions. For example, the preset working cycle is one hour. Of course, the preset working cycle can also be set to other non-negative values. This application does not impose any restrictions on this.
[0122] The base station queries the operational status of multiple seabed observation nodes and counts the number of currently online nodes. For example, if the preset operational cycle is one hour and there are four online seabed observation nodes, then each node is allocated a communication window of 15 minutes. The base station sorts the four seabed observation nodes according to a preset order and allocates communication windows to each node sequentially. The preset sorting order can be based on the size of the seabed observation nodes' IP addresses.
[0123] S303. Receive underwater sampling data reported by the seabed observation node within the communication window corresponding to the seabed observation node.
[0124] Please see Figure 3b , Figure 3bThis application provides a timing diagram for communication between a base station and a seabed observation node. The master node represents the base station, and child nodes 1, 2, and 3 represent seabed observation nodes 1, 2, and 3, respectively. The base station allocates a corresponding communication window for each seabed observation node and requests data reporting from the node within that window. Upon receiving the data request, the seabed observation node reports data to the base station within its corresponding communication window. After receiving the data reported by the seabed observation node, the base station sends an ACK confirmation packet to that node. If the base station does not receive the data reported by the seabed observation node or if the data received contains errors, the base station sends a NACK packet to that node. The NACK packet contains an error code to inform the seabed observation node to retransmit the data that needs to be reported. If the base station requests data from a seabed observation node but does not receive the reported data within a timeout period, the base station skips that node and records the error information.
[0125] This application provides an underwater data receiving method. The method includes: querying the working status of multiple seabed observation nodes; allocating a communication window to each of the multiple seabed observation nodes according to the working status and a preset working period; and receiving underwater sampling data reported by the seabed observation node within the communication window corresponding to the seabed observation node. Therefore, the base station allocates a communication window to the seabed observation node according to its working status and a preset working period, and receives the underwater sampling data reported by that seabed observation node within its corresponding communication window. This demonstrates that the communication window for the seabed observation node to send data to the base station is allocated by the base station for that seabed observation node, and is not randomly allocated, effectively avoiding signal superposition caused by multiple seabed observation nodes simultaneously sending data to the base station, thereby reducing the signal error rate.
[0126] Please see Figure 4 , Figure 4 This is a second flowchart illustrating an underwater data receiving method provided in this application. In one embodiment, after allocating a communication window to each of the plurality of seabed observation nodes according to the working state and a preset working period, the method further includes:
[0127] S401. Send the communication window corresponding to the seabed observation node to each of the multiple seabed observation nodes.
[0128] It should be noted that the above embodiments of this application have detailed the reception of the communication window allocated to the seabed observation node by the base station from the seabed observation node. This will not be repeated here.
[0129] Please see Figure 5, Figure 5 This is a third schematic flowchart illustrating an underwater data receiving method provided in an embodiment of this application. In one embodiment, the method further includes:
[0130] S501: Send data priority signaling to multiple seabed observation nodes.
[0131] Among them, the data priority signaling is used to instruct each of the multiple seabed observation nodes to send the target underwater sampling data to the base station according to the priority of the underwater sampling data.
[0132] It should be noted that the data priority signaling has been described in detail in the above embodiments of this application. Therefore, this application will not repeat it.
[0133] In one embodiment, the method further includes:
[0134] Time information is sent to multiple seabed observation nodes, and the time information is used for time synchronization between the multiple seabed observation nodes and the base station.
[0135] It should be noted that the time information has been described in detail in the above embodiments of this application. Therefore, this application will not repeat it again.
