[0038] Please refer to Figure 1 , Figure 1 is a structural schematic diagram of a communication system for implementing a communication method of a marine operation platform in a public network-free state provided by the embodiments of the present application, as shown in the figure, the communication system includes: flight equipment, cloud equipment and m communication equipment, m is an integer greater than 1; based on the flight equipment in the communication system, the following functions can be realized:

[0039] In the process of executing the marine flight task by the flight equipment, a first flight route and a first flight trajectory of the flight equipment are acquired; the first flight route includes a current position of the flight equipment;

[0040] A first deviation degree between the first flight route and the first flight trajectory is determined;

[0048] The cloud device can include a cloud platform, a cloud server, and the like, and is not limited herein. The cloud device can include a command center.

[0049] According to the present application, when the first deviation is less than a preset threshold, it can be understood that the flight device is flying according to a preset trajectory. The corresponding n communication devices can be determined based on the position. Since the n communication devices are known in advance, the communication links corresponding to the n communication devices can also be planned in advance, that is, the communication links can be quickly determined. In addition, the data processing is performed based on the actual flight speed to improve the communication stability, reduce the time delay, and improve the anti-interference capability, thereby ensuring the communication efficiency between the flight device and the cloud device, and further improving the communication efficiency of the helicopter during the offshore operation.

[0050] Please refer to Figure 2 , Figure 2 is a flowchart of a communication method of an offshore operation platform in a non-public network state according to an embodiment of the present application. As shown in the figure, the communication method is applied to a flight device in a communication system, and the communication system includes a cloud device and m communication devices, where m is an integer greater than 1. The communication method of the offshore operation platform in the non-public network state includes the following steps.

[0051] 201. During the execution of the offshore flight task by the flight device, a first flight route and a first flight trajectory of the flight device are obtained. The first flight route includes the current position of the flight device.

[0052] In a specific implementation, during the execution of the offshore flight task by the flight device, the starting position and the end position of the flight device are known because the task content is known. The first flight route can be planned based on the starting position and the end position, so that the first flight route can be planned in advance before the flight device takes off. The flight distance or the flight time or the flight distance (the distance between the starting position and the end position) can be estimated based on the first flight route.

[0053] In specific implementation, during the flight device performs the flight task on the sea, the position of the flight device can be recorded at every preset time interval, so that the flight track of the flight device can be obtained, wherein the preset time interval can be pre-set or system default. For example, the preset time interval can be related to the flight distance, or the preset time interval can be related to the flight time, or the preset time interval can be related to the flight distance.

[0054] In specific implementation, during the flight device performs the flight task on the sea, the first flight route and the first flight track of the flight device can be obtained, the first flight route includes the current position of the flight device, the current position can be understood as the position of the flight device recorded last time or the position of the current positioning, the first flight route and the first flight track can be used to detect whether the flight device flies according to the predetermined track, or the degree of the flight device detecting the predetermined track can also be detected.

[0055] 202. Determine a first deviation degree between the first flight route and the first flight track.

[0056] In specific implementation, the straight line distance between the current position and the first flight track can be determined, the mapping relationship between the preset distance and the deviation degree can be pre-stored, and then the first deviation degree corresponding to the straight line distance can be determined based on the mapping relationship, the greater the first deviation degree, the greater the degree of the flight device deviating from the predetermined track.

[0057] 203. When the first deviation degree is less than a preset threshold, determine n communication devices corresponding to the current position, the m communication devices include the n communication devices; n is a natural number less than m.

[0058] The preset threshold can be pre-set or system default. In specific implementation, the communication devices corresponding to different positions can be pre-planned, and the corresponding communication devices can be selected based on different positions, so as to establish a communication link by using these communication devices, so as to realize the communication between the cloud device and the flight device.

[0059] In specific implementation, a pre-stored mapping relationship between preset locations and communication device identifier sets can be stored. Each communication device identifier set can include at least one communication device identifier, which is used to uniquely identify the communication device. The communication device identifier can include at least one of the following: device number, IP address, physical address, etc., without limitation. Furthermore, when the first deviation is less than a preset threshold, it can be understood that the flight device flies according to a preset trajectory. Based on this mapping relationship, the first communication device identifier set corresponding to the current location can be determined, and n communication devices corresponding to the first communication device identifier set can be obtained. Based on these n communication devices, the communication link between the flight device and the cloud device can be determined. Since the corresponding communication devices are pre-configured based on different locations to form corresponding communication links, communication time can be saved, and the communication efficiency between the flight device and the cloud device can be guaranteed.

[0060] 204. Determine the first communication link between the flight equipment and the cloud equipment based on the n communication devices.

[0061] In practice, since the n communication devices are known in advance, the communication links corresponding to the n communication devices can also be planned in advance. Therefore, the first communication link between the flight equipment and the cloud equipment can be determined based on the n communication devices. Since the corresponding communication devices are configured in advance based on different locations to form the corresponding communication links, communication time can be saved and the communication efficiency between the flight equipment and the cloud equipment can be guaranteed.

[0062] Among them, such as Figure 3 As shown, the flight equipment establishes a communication link with the cloud equipment through n communication devices.

[0063] 205. Obtain a first message; the first message includes at least the first flight data of the flight equipment, and the first flight data includes at least the first flight speed.

[0064] The first flight data may include not only the first flight speed, but also at least one of the following: first flight altitude, fuel level of the flight equipment, battery level of the flight equipment, heading of the flight equipment, real-time images captured by the flight equipment, personnel status of the flight equipment, flight duration of the flight equipment, position of the flight equipment, deviation of the flight equipment, flight trajectory of the flight equipment, meteorological data collected by the flight equipment, operational data of the flight equipment, etc., without limitation.

[0065] In practice, the flight equipment can obtain a first message, which includes at least the first flight data of the flight equipment, including at least the first flight speed. Then, the first message can be synchronized to the cloud equipment, thereby maintaining continuous communication between the flight equipment and the cloud equipment, recording the flight status of the flight equipment in real time, and thus ensuring flight safety.

[0066] Optionally, the first message may further include message content, which may include at least one of the following: voice content, text content, string content, and video content.

[0067] The message content may include at least one of the following: voice content, text content, string content, video content, etc., without limitation.

[0068] In practice, the flight equipment can not only transmit flight data in real time, but also transmit other information to maintain synchronous communication with cloud devices, so that the cloud can have a clearer understanding of the real-time status of the flight equipment and the real-time status of the personnel on the flight equipment.

[0069] 206. Determine the first data processing parameters corresponding to the first flight speed.

[0070] The first data processing parameter may include at least one of the following: communication protocol, data packaging parameters, data compression parameters, data encryption / decryption parameters, data transmission rate, data encoding / decoding parameters, etc., without limitation. For example, in a specific implementation, taking a helicopter as an example, the impact of the helicopter's flight speed on maritime communication is mainly reflected in communication stability, latency, and anti-interference capability. Therefore, based on the impact of the actual flight speed, corresponding data processing can be performed to improve communication stability, reduce latency, and enhance anti-interference capability, thereby ensuring the communication efficiency between the flight equipment and the cloud equipment.

[0071] In a specific implementation, a pre-defined mapping relationship between flight speed and data processing parameters can be stored in advance. Then, the first data processing parameters corresponding to the first flight speed can be determined based on this mapping relationship.

[0072] Optionally, the first communication link includes multiple communication links formed by the flight equipment, the n communication devices, and the cloud equipment connected in series; the first data processing parameters include a first packaging algorithm and a first packaging control parameter; step 206 above, determining the first data processing parameters corresponding to the first flight data, includes:

[0073] A first communication link and k second communication links are determined. The first communication link includes the communication link between the flight equipment and a first communication device, where the first communication device is one of the n communication devices that directly communicates with the flight equipment. Each of the k second communication links is a communication link formed by two adjacent communication devices in the first communication link. k is a positive integer.

[0074] Determine the first channel quality assessment value for the first segment of the communication link;

[0075] Determine the channel quality assessment value for each of the k second-segment communication links to obtain k second-channel quality assessment values;

[0076] Determine the minimum value among the first channel quality assessment value and the k second channel quality assessment values;

[0077] Determine the first communication protocol parameters corresponding to the minimum value;

[0078] Determine the first packetization algorithm corresponding to the first communication protocol parameters;

[0079] Determine the first packing control parameters corresponding to the first packing algorithm corresponding to the first flight speed.

[0080] The first communication link may include multiple communication links formed by connecting flight equipment, n communication devices and cloud devices in series.

[0081] The first data processing parameters may include a first packing algorithm and first packing control parameters. The first packing control parameters can be used to control the packing effect, which may include at least one of the following: packing speed, data packet size, data packet anti-interference capability, etc., which are not limited here.

[0082] The first packing algorithm may include at least one of the following: greedy algorithm, dynamic programming algorithm, genetic algorithm, neural network algorithm, Huffman algorithm, etc., without limitation.

[0083] In a specific implementation, the first communication link can be regarded as multiple communication links. Each communication link can be composed of two devices with communication functions. Then, the first communication link and k second communication links can be determined. The first communication link includes the communication link between the flight equipment and the first communication device. The first communication device is the communication device that directly communicates with the flight equipment among the n communication devices. Each of the k second communication links is a communication link formed by two adjacent communication devices in the first communication link; k is a positive integer.

[0084] In specific implementation, channel quality assessment parameters of the first communication link can be obtained. Based on these parameters, a first channel quality assessment value for the first communication link can be determined. These parameters can include at least one of the following: channel bandwidth, signal-to-noise ratio, transmission rate, bit error rate, latency, capacity, bandwidth efficiency, reliability, anti-interference capability, etc., without limitation. Specifically, channel testing can be performed on the first communication link to obtain its channel quality assessment parameters. If multiple parameters are included, a corresponding channel quality assessment can be performed for each parameter to obtain multiple channel quality assessment values. These values ​​are then weighted and calculated to obtain the first channel quality assessment value.

[0085] Correspondingly, the channel quality assessment value of each of the k second-segment communication links can be determined in the manner described above, resulting in k second-segment channel quality assessment values. Then, the minimum value among the first channel quality assessment value and the k second-segment channel quality assessment values ​​can be determined. Furthermore, a pre-defined mapping relationship between the channel quality assessment values ​​and communication protocol parameters can be stored in advance. The communication protocol parameters may include at least one of the following: communication protocol identifier, communication protocol type, baud rate, number of start bits, number of data bits, parity bit, stop bit, station address, PDO identifier (COB-ID), transmission type, forbidden time, etc., which are not limited here.

[0086] Next, the first communication protocol parameter corresponding to the minimum value can be determined according to the preset mapping relationship between the channel quality assessment value and the communication protocol parameter. The preset mapping relationship between the communication protocol parameter and the packetization algorithm can also be stored in advance. Based on the mapping relationship, the first packetization algorithm corresponding to the first communication protocol parameter can be determined. The mapping relationship between the flight speed and the packetization control parameter corresponding to the first packetization algorithm can also be stored in advance. Then, the first packetization control parameter corresponding to the first packetization algorithm corresponding to the first flight speed can be determined based on the mapping relationship.

[0087] In this example, firstly, the communication link can be segmented, and the channel quality assessment value of each segment can be determined. That is, the "barrel principle" is used to determine the channel quality assessment value corresponding to the minimum value, and the corresponding communication protocol parameters are adapted. In this way, the optimal balance of data transmission reliability, efficiency, and real-time performance can be achieved by dynamically adapting to channel characteristics. Secondly, based on the communication protocol parameters, the corresponding packetization algorithm is adapted to improve the anti-interference capability of data by optimizing the data encapsulation strategy, thereby achieving the optimal balance of transmission efficiency, reliability, and resource utilization. Thirdly, based on the impact of actual flight speed, the data transmission encapsulation strategy and flight status are dynamically coordinated to achieve the optimal balance of communication efficiency, real-time performance, and reliability. In this way, communication stability is improved, latency is reduced, and anti-interference capability is enhanced, thereby ensuring the communication efficiency between the flight equipment and the cloud equipment.

[0088] 207. Process the first message according to the first data processing parameters to obtain the second message.

[0089] In practice, the first message can be processed by the first data processing parameters to obtain the second message. That is, based on the impact of the actual flight speed, corresponding data processing can be performed to improve communication stability, reduce latency, and enhance anti-interference capabilities, thereby ensuring the communication efficiency between the flight equipment and the cloud equipment.

[0090] Optionally, when the current location is the designated area and the first message includes the first flight data and message content, the following steps may also be included:

[0091] Keyword extraction is performed on the message content to obtain the target keywords;

[0092] Determine the first encryption algorithm and the first encryption control parameters corresponding to the target keyword;

[0093] The first encryption control parameters are optimized based on the first packaging algorithm to obtain the second encryption control parameters;

[0094] The message content is encrypted according to the first encryption algorithm and the second encryption control parameters to obtain the ciphertext message content;

[0095] Determine the first decryption control parameter corresponding to the second encryption control parameter;

[0096] The encryption algorithm identifier of the first encryption algorithm is converted into a first string according to the first ciphertext;

[0097] The first identifier of the first encrypted text and the first string are concatenated to obtain the target first string;

[0098] The first decryption control parameter is converted into a second string according to the second ciphertext corresponding to the first ciphertext.

[0099] The second identifier of the second encrypted text and the second string are concatenated to obtain the target second string;

[0100] The target first string, the target second string, and the ciphertext message content are concatenated to obtain the concatenated ciphertext message content;

[0101] The concatenated encrypted message content and the first flight data are processed according to the first data processing parameters to obtain the second message.

[0102] In specific implementation, keyword extraction can be performed on the message content to obtain target keywords. Keywords can include at least one of the following: strings, timbres, tones, patterns, repetitive fields, etc., without limitation. A pre-stored mapping relationship between preset keywords and encryption algorithms can be used. Then, based on this mapping relationship, the first encryption algorithm corresponding to the target keyword can be determined. Furthermore, a pre-stored mapping relationship between preset keywords and encryption control parameters of the first encryption algorithm can be used. Then, based on this mapping relationship, the first encryption control parameters corresponding to the target keyword can be determined. The encryption control parameters can be used to control the encryption effect of the first encryption algorithm. This encryption effect can include at least one of the following: encryption complexity, encryption speed, encryption range, etc., without limitation.

[0103] Next, the algorithm identifier of the packaging algorithm can be obtained. The algorithm identifier can be used to uniquely identify the packaging algorithm. The mapping relationship between the algorithm identifier of the packaging algorithm and the optimization coefficient of the first encryption control parameter can be stored in advance. The value range of the optimization coefficient can be preset or defaulted by the system. For example, the value range of the optimization coefficient can be -0.1 to 0.1. Then, the first optimization coefficient corresponding to the algorithm identifier of the first packaging algorithm can be determined based on the mapping relationship. Then, based on the first optimization coefficient, some or all of the parameters in the first encryption control parameter are optimized to obtain the second encryption control parameter. The second encryption control parameter = (1 + first optimization coefficient) × first encryption control parameter.

[0104] Next, the message content can be encrypted again according to the first encryption algorithm and the second encryption control parameters to obtain the ciphertext message content. Of course, the first decryption control parameters corresponding to the second encryption control parameters can also be determined. Since the encryption parameters are fixed, the corresponding decryption parameters are also fixed. The first ciphertext and the second ciphertext can be preset or defaulted to by the system. The first ciphertext and the second ciphertext are agreed upon internally by the communication system. The second ciphertext corresponds to the first ciphertext. The second ciphertext is used to convert the decryption control parameters of the first encryption algorithm. The first ciphertext is equivalent to a mapping relationship, specifically used to convert the algorithm identifier of the encryption algorithm into a string. The second ciphertext is equivalent to a mapping relationship, specifically used to convert the first decryption control parameters into a string. The first identifier of the first ciphertext is used to uniquely identify the first ciphertext, and the second identifier of the second ciphertext is used to uniquely identify the second ciphertext. The first identifier and the second identifier can include: number, string, etc., which are not limited here. The encryption algorithm identifier of the first encryption algorithm can be converted into a first string according to the first ciphertext, which is equivalent to disguising the algorithm identifier as the first string. Of course, data compression can also be achieved by concatenating the first identifier of the first ciphertext and the first string to obtain the target first string. The concatenation position can be fixed or dynamically changed. For example, the concatenation position can be related to time, or it can be related to the deviation of the flight equipment, or it can be related to the position of the flight equipment.

[0105] Next, the first decryption control parameter is converted into a second string according to the second ciphertext corresponding to the first ciphertext. This is equivalent to disguising the first decryption control parameter as the second string. Of course, data compression can also be achieved by concatenating the second identifier of the second ciphertext with the second string to obtain the target second string. The concatenation position can be fixed or dynamically changed. For example, the concatenation position can be related to time, or it can be related to the deviation of the flight equipment, or it can be related to the position of the flight equipment.

[0106] Furthermore, the target first string, the target second string, and the ciphertext message content can be concatenated to obtain the concatenated ciphertext message content. The concatenation position of the three can be fixed or dynamically changed. For example, the concatenation position can be related to time, or it can be related to the deviation of the flight equipment, or it can be related to the position of the flight equipment. The concatenated ciphertext message content and the first flight data are processed according to the first data processing parameters to obtain the second message.

[0107] In this example, firstly, keywords represent the importance of the message content. Therefore, the corresponding encryption algorithm and encryption control parameters can be determined based on the importance of the message content, thus ensuring the security of the message content. Secondly, the encryption control parameters can be further optimized based on the packaging characteristics, and corresponding encryption can be performed. This ensures not only security but also better completion of subsequent packaging operations. Thirdly, the algorithm identifier of the first encryption algorithm and the decryption control parameters can be disguised based on a pre-agreed ciphertext. Of course, the relevant identifier information of the two ciphertexts is also disguised. These are then concatenated with the ciphertext message content to obtain the concatenated ciphertext message content. This concatenated ciphertext message content and the first flight data are then packaged together. Since the cloud device, after receiving the second message, can first package it and identify the fields containing the first string, the second string, the first identifier, and the second identifier, it can quickly obtain the agreed ciphertext according to the first and second identifiers and restore it according to the agreed ciphertext. This allows for rapid identification of decryption-related parameters and decryption of the ciphertext message content, thus quickly obtaining the relevant message content. This ensures both message security and decryption efficiency, facilitating the rapid transmission of important information between the communicating parties.

[0108] 208. Transmit the second message to the cloud device through the first communication link.

[0109] In practice, the second message can be transmitted to the cloud device through the first communication link. Due to the impact of the actual flight speed, corresponding data processing is performed to improve communication stability, reduce latency, and enhance anti-interference capabilities, thereby ensuring the communication efficiency between the flight equipment and the cloud device.

[0110] Optionally, the flight equipment may also include a weather monitoring device, and may further include the following steps:

[0111] When the first deviation is greater than or equal to the preset threshold, the first meteorological data is acquired through the meteorological monitoring device;

[0112] Determine the first communication distance range corresponding to the first meteorological data;

[0113] The communication devices within the first communication distance range are determined to be 'a' communication devices, and the m communication devices include the 'a' communication devices; where 'a' is a positive integer.

[0114] Determine the distances between the flight equipment and the a communication devices to obtain a distance values;

[0115] Select the minimum distance value among the a distance values, and determine the second communication device corresponding to the minimum distance value;

[0116] Determine at least one set of communication devices corresponding to the second communication device, wherein each set of communication devices in the at least one set of communication devices includes the second communication device and a device capable of communicating with the cloud device, and the second communication device is directly used to communicate with the flight device;

[0117] Determine at least one communication link corresponding to the at least one set of communication devices; determine the channel quality assessment value of each communication link in the at least one communication link to obtain at least one channel quality assessment value;

[0118] Select the maximum value among the at least one channel quality assessment value, and obtain the target communication device set corresponding to the maximum value;

[0119] A second communication link between the flight equipment and the cloud equipment is determined based on the target communication device set.

[0120] The flight equipment also includes a meteorological monitoring device, which can be used to detect the weather conditions around the flight equipment. The primary meteorological data may include at least one of the following: temperature, humidity, air density, rainfall, weather type (rain, sunshine, hail, snow, typhoon, etc.), airflow direction, wind direction, atmospheric pressure, etc., without limitation.

[0121] In specific implementation, when the first deviation is greater than or equal to a preset threshold, it indicates that the flight equipment is not flying according to the preset flight trajectory, i.e., the flight equipment is deviating somewhat. First meteorological data can be obtained through a meteorological monitoring device, and then the first communication distance range corresponding to the first meteorological data can be determined. Since different meteorological data have different effects on communication, and flight is more cautious in adverse environments, the main consideration is the impact of weather on communication. For example, a first influence coefficient corresponding to the first meteorological data can be determined. Specifically, the first meteorological data can include at least one meteorological data item. For example, a preset mapping relationship between each meteorological data item and its influence coefficient can be stored in advance. Then, based on this mapping relationship, the influence coefficient corresponding to the corresponding meteorological data can be determined, obtaining at least one influence coefficient. Then, a weighted operation is performed on this at least one influence coefficient to obtain the first influence coefficient. Next, a preset mapping relationship between the influence coefficient and the communication distance range is stored in advance. Then, based on this mapping relationship, the first communication distance range corresponding to the first influence coefficient can be determined. Finally, a search is performed based on this first communication distance range to determine the communication equipment within the first communication distance range, resulting in 'a' communication equipment. The m communication equipment includes 'a' communication equipment; 'a' is a positive integer.

[0122] Next, the distances between the flight equipment and a communication devices can be determined, resulting in a distance values. The minimum distance value among the a distance values ​​is selected, and the second communication device corresponding to the minimum distance value is determined. Then, at least one set of communication devices corresponding to the second communication device is determined. Each set of at least one communication device includes the second communication device and a device capable of communicating with the cloud device. The second communication device is directly used to communicate with the flight equipment. At least one communication link corresponding to at least one set of at least one communication device is then determined. The channel quality assessment value of each communication link in the at least one communication link is determined, resulting in at least one channel quality assessment value. This step can be implemented based on the above channel quality assessment principle. The maximum value among the at least one channel quality assessment value is then selected, and the target communication device set corresponding to the maximum value is obtained. Finally, the second communication link between the flight equipment and the cloud device is determined based on the target communication device set.

[0123] In this example, firstly, when the first deviation is greater than or equal to a preset threshold, it indicates that the flight equipment is not flying according to the preset flight trajectory, meaning the flight equipment is deviating somewhat. Therefore, a first matching communication distance range can be determined based on meteorological data, and then the nearest communication device can be searched within this range to ensure the effectiveness of the communication link. Secondly, based on this nearest communication device, the communication link with the best channel is determined to further ensure communication performance. Thus, the communication efficiency between the flight equipment and the cloud equipment is guaranteed.

[0124] Optionally, the following steps may also be included:

[0125] Obtain a third message; the third message includes at least the second flight data of the flight equipment, and the second flight data includes at least: first meteorological data;

[0126] Determine the second data processing parameters corresponding to the first meteorological data;

[0127] The third message is processed according to the second data processing parameters to obtain the fourth message;

[0128] The fourth message is transmitted to the cloud device via the second communication link.

[0129] The second flight data may include not only the first meteorological data, but also at least one of the following: flight altitude, fuel level of the flight equipment, battery level of the flight equipment, heading of the flight equipment, real-time images captured by the flight equipment, personnel status of the flight equipment, flight duration of the flight equipment, location of the flight equipment, deviation of the flight equipment, flight trajectory of the flight equipment, operational data of the flight equipment, etc., without limitation.

[0130] In practice, the flight equipment can obtain a third message, which includes at least the second flight data of the flight equipment. The second flight data includes at least the first meteorological data. Then, the third message can be synchronized to the cloud equipment, thereby maintaining continuous communication between the flight equipment and the cloud equipment, recording the flight status of the flight equipment in real time, and transmitting real-time weather to the cloud equipment to ensure the efficiency of subsequent flight guidance and thus ensure flight safety.

[0131] The second data processing parameter may include at least one of the following: communication protocol, data packaging parameters, data compression parameters, data encryption / decryption parameters, data transmission rate, data encoding / decoding parameters, etc., without limitation. For example, in a specific implementation, the impact of weather on maritime helicopter communication is mainly reflected in communication quality, stability, and security. Therefore, based on the impact of weather, corresponding data processing can be performed to improve communication quality, stability, and security, thereby ensuring the communication efficiency between the flight equipment and the cloud equipment.

[0132] In practice, a pre-stored mapping relationship between meteorological data and data processing parameters can be used. Then, based on this mapping relationship, the second data processing parameters corresponding to the first meteorological data can be determined. The third message can then be processed according to the second data processing parameters to obtain the fourth message. Finally, the fourth message can be transmitted to the cloud device through the second communication link. In this way, based on the impact of meteorology, corresponding data processing can be performed to improve communication quality, communication stability, and communication security, thereby ensuring the communication efficiency between the flight equipment and the cloud device.

[0133] Optionally, the third message may further include message content, which may include at least one of the following: voice content, text content, string content, or video content.

[0134] The message content may include at least one of the following: voice content, text content, string content, video content, etc., without limitation.

[0135] In practice, the flight equipment can not only transmit flight data in real time, but also transmit other information to maintain synchronous communication with cloud devices, so that the cloud can have a clearer understanding of the real-time status of the flight equipment and the real-time status of the personnel on the flight equipment.

[0136] Optionally, the second data processing parameters include a second packaging algorithm and a second packaging control parameter. The above steps, determining the second data processing parameters corresponding to the first meteorological data, can be implemented in the following manner:

[0137] Determine the second communication protocol parameter corresponding to the maximum value;

[0138] Determine the second packetization algorithm with respect to the second communication protocol parameters;

[0139] Determine the second packaging control parameters corresponding to the second packaging algorithm corresponding to the first meteorological data.

[0140] The second data processing parameter may include a second packing algorithm and a second packing control parameter. The second packing control parameter can be used to control the packing effect, which may include at least one of the following: packing speed, data packet size, data packet anti-interference capability, etc., which are not limited here.

[0141] The second packing algorithm may include at least one of the following: greedy algorithm, dynamic programming algorithm, genetic algorithm, neural network algorithm, Huffman algorithm, etc., without limitation.

[0142] In specific implementation, since a pre-stored mapping relationship between preset channel quality assessment values ​​and communication protocol parameters can be stored, the communication protocol parameters may include at least one of the following: communication protocol identifier, communication protocol type, baud rate, number of start bits, number of data bits, parity bit, stop bit, station address, PDO identifier (COB-ID), transmission type, forbidden time, etc., which are not limited here. Next, the second communication protocol parameter corresponding to the maximum value can be determined according to the pre-stored mapping relationship between the channel quality assessment value and the communication protocol parameters.

[0143] Next, a pre-stored mapping relationship between preset communication protocol parameters and packing algorithms can be stored. Based on this mapping relationship, the second packing algorithm corresponding to the second communication protocol parameters can be determined. A pre-stored mapping relationship between preset meteorological data and packing control parameters corresponding to the second packing algorithm can also be stored. Based on this mapping relationship, the second packing control parameters corresponding to the second packing algorithm corresponding to the first meteorological data can be determined.

[0144] In this example, firstly, the optimal balance between data transmission reliability, efficiency, and real-time performance can be achieved by dynamically adapting to channel characteristics. Secondly, the corresponding packetization algorithm can be adapted based on the communication protocol parameters to improve data anti-interference capabilities by optimizing data encapsulation strategies, thereby achieving the optimal balance between transmission efficiency, reliability, and resource utilization. Thirdly, based on the impact of weather, corresponding data processing can be performed to improve communication quality, communication stability, and communication security, thereby ensuring the communication efficiency between the flight equipment and the cloud equipment.

The communication system includes a cloud device and m communication devices, where m is an integer greater than 1.

Firstly, when the first deviation is less than a preset threshold, it can be understood that the flight equipment flies according to a preset trajectory, and the corresponding n communication devices can be determined based on the position. Since the n communication devices are known in advance, the communication links corresponding to the n communication devices can also be planned in advance, that is, the communication links can be quickly determined. Secondly, based on the impact of the actual flight speed, corresponding data processing is performed to improve communication stability, reduce latency, and improve anti-interference capability, thereby ensuring the communication efficiency between the flight equipment and the cloud device, and thus helping to improve the communication efficiency of helicopters during maritime operations.
