[0071] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application may also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of this application with unnecessary detail.

[0072] To illustrate the technical solution described in this application, specific embodiments are provided below.

[0073] As one of the most important means of transportation for humans, the reliability and stability of the power system are crucial to the safety and comfort of ships. Inverters, as key equipment for power conversion, provide ships with stable and efficient power conversion solutions. Therefore, monitoring inverter operating data is particularly important. By monitoring the inverter's operating parameters, we can effectively understand its operating status, promptly detect potential anomalies, and perform timely maintenance when possible, thereby improving the reliability and stability of the power system.

[0074] However, the network environment for shipboard operations is often harsh; for example, a ship's route may pass through uninhabited areas or regions far from land. If the inverter's network signal is weak, its operational data cannot be uploaded to the server. Because inverters have limited cache space, if the cached data exceeds the available space, it may lead to data loss, hindering better monitoring of the inverter's operating status and potentially preventing timely detection of inverter anomalies. This ultimately negatively impacts the stability and reliability of the inverter's operation.

[0075] Figure 1 This is a schematic diagram illustrating an implementation scenario of a data transmission method for an inverter provided in this application. The implementation scenario includes an inverter 1, a smart terminal 2, and a server 3. The inverter 1 includes a first network 11 and a first Bluetooth module 12. The smart terminal 2 includes a second network 21 and a second Bluetooth module 22. When the inverter 1 can establish a communication connection with the server through the first network 11, the operating data of the inverter 1 can be uploaded to the server 3 through the first network 11. When the inverter 1 cannot establish a communication connection with the server through the first network 11, the smart terminal 2 can receive a disconnection message. The inverter can then activate the first Bluetooth module 12. Based on the inverter 1's identifier included in the disconnection message, the smart terminal 2 searches for the inverter name corresponding to the inverter identifier in the Bluetooth device list. Based on this inverter name, it establishes a Bluetooth link with the inverter 1 using the second Bluetooth module 22, receives the operating data uploaded by the inverter, and uploads it to the server through the second network 21.

[0076] The first network 11 can be a mobile communication network. The mobile communication network can include at least one of the following: 5G network, 4G network, 3G network, 2G network, or other mobile communication networks.

[0077] The second network 21 may include a mobile communication network or a satellite communication network. When the inverter 1 cannot establish a communication connection with the server through the first network 11, the smart terminal 2 may establish a communication connection with the server 3 through the second network 21, or the smart terminal 2 may cache the operating data in its storage space and transmit the operating data to the server 3 when the link of the second network 21 between the smart terminal 2 and the server 3 is normally connected.

[0078] Among them, the intelligent terminal 2 is a device that can be used to recover the operating data of the inverter 1 when the inverter 1 is in a communication abnormal state.

[0079] Figure 2 A schematic diagram illustrating the implementation flow of a data transmission method for an inverter provided in this application embodiment is described in detail below:

[0080] In S201, the disconnection message of the inverter is monitored, and the disconnection message includes the identifier of the disconnected inverter.

[0081] The inverter in this embodiment is a device that converts direct current (DC) to alternating current (AC). By converting DC power to AC power and controlling parameters such as output voltage, frequency, and current, it meets the needs of different electrical loads.

[0082] During operation, the inverter transmits operational data generated during operation to the server via a first network. This operational data may include at least one of the following: DC input parameters, AC output parameters, conversion efficiency, environmental parameters, and power generation data. Specifically, DC input parameters may include at least one of the following: maximum input power, maximum input voltage, operating voltage range, and maximum current. AC output parameters may include at least one of the following: maximum output power, AC voltage, AC frequency, rated output power, rated output current, maximum output current, and power factor. Environmental parameters may include at least one of the following: operating temperature range and noise level. Power generation data may include at least one of the following: inverter power generation and irradiance.

[0083] In this embodiment, the disconnection message is generated when the inverter cannot establish a communication link with the server through the first network. Normally, the inverter establishes a communication link with the server through the first network, and operating data is transmitted to the server via this link. If the server cannot receive operating data through the first network, it indicates that the inverter is disconnected, and a disconnection message is generated. The disconnection message includes the identifier of the disconnected inverter, which uniquely identifies the disconnected inverter, thus enabling accurate recovery of the inverter's operating data.

[0084] In this embodiment of the application, the disconnection message of the inverter is monitored by a smart terminal, and the disconnection message can be determined in a variety of ways.

[0085] For example, a disconnection message can be sent to a smart terminal via a server. When the server detects that the communication link between the inverter and the server based on the first network is broken, or when the server detects that the duration of failure to receive the inverter's operating data exceeds a predetermined time threshold, it determines that the communication link between the server and the inverter based on the first network is disconnected. Based on the second location information of the disconnected inverter, the relevant smart terminal can be identified, and a disconnection message can be generated and sent to the relevant smart terminal.

[0086] In this situation, the server generates a disconnection message based on the identifier of the inverter that failed to receive operating data, or based on the identifier of the inverter that disconnected the link.

[0087] In order to accurately send the disconnection message to the smart terminal that can perform data recovery, the server in this embodiment can also determine the smart terminal to which the disconnection message needs to be sent before sending the disconnection message.

[0088] For example, when the inverter is a ship-mounted inverter, it is necessary to determine that the distance between the smart terminal and the inverter is less than a predetermined distance threshold, or that the smart terminal is within the location range defined by the inverter. The smart terminal that meets either the distance condition or the location range condition will be selected as the target smart terminal for which the disconnection message needs to be sent. The location range defined by the inverter can be a range defined by a predetermined radius centered on the inverter.

[0089] The disconnection message in this embodiment can also be determined by the smart terminal when the communication link between the smart terminal and the server is disconnected. The communication link between the smart terminal and the server is either a communication link determined by the second network or a communication link determined by the mobile communication network. The specific process for determining the disconnection message is as follows: Figure 3 As shown, it includes:

[0090] In S301, the communication link between the smart terminal and the server is monitored.

[0091] Smart terminals monitor the communication link between the server and the smart terminal, such as the mobile communication network between the server and the smart terminal.

[0092] When the inverter is used in transportation vehicles such as ships operating in environments with weak network signals, the communication quality of smart terminals used by users on these vehicles may be affected by the network signal. When the mobile communication network is functioning normally, the smart terminal can establish a normal communication link with the server and receive the inverter's operating status monitored and calculated by the server. When the mobile communication network is abnormal, such as being disconnected, the smart terminal cannot receive data sent by the server, and the smart terminal can detect that the communication link is broken.

[0093] In S302, when the communication link between the smart terminal and the server is disconnected, the first location information of the smart terminal is obtained.

[0094] In this embodiment, the inverter is typically located inside the device. Due to obstruction by walls or other equipment, the communication quality of the inverter's mobile communication network is usually weaker than that of the smart terminal's mobile communication network. Therefore, when the communication link between the smart terminal and the server malfunctions, such as being disconnected, it can usually be determined that the communication link between the inverter and the server is disconnected. In this case, the first location information of the smart terminal can be obtained to generate the identifier in the disconnection information.

[0095] For example, the initial location information of a smart terminal can be determined through satellite positioning signals, including GPS positioning signals or BeiDou satellite positioning information. Alternatively, the location of the smart terminal can be determined based on its environment, such as through positioning base stations. Positioning base stations can include mobile communication positioning base stations, etc.

[0096] In S303, the identifier of the inverter associated with the first positioning information is determined.

[0097] To improve the efficiency of rescuing smart terminals, embodiments of this application can further determine the identifier of the inverter that needs to be rescued by the smart terminal that detected the disconnection message, enabling the smart terminal that detected the disconnection message to quickly locate the inverter that needs to be rescued for operational data based on the identifier. When the inverter is an inverter on a transportation vehicle such as a ship, determining the identifier of the relevant inverter based on the first certain information of the smart terminal can be as follows: Figure 4 As shown, it includes:

[0098] In S401, the first positioning information of the smart terminal and the second positioning information of the inverter are obtained.

[0099] The first location information of the smart terminal can be determined through a mobile communication base station or a satellite positioning system. The second location information of the inverter can also be determined through a mobile communication base station. Since the inverter's mobile communication network may be unstable, the second location information of the inverter can be obtained when the inverter's mobile communication network is stable.

[0100] The first location information and the second location information can be within the same time period, such as location information determined when the mobile communication network is stable.

[0101] In S402, a first trajectory is determined based on the first positioning information, and a second trajectory is determined based on the second positioning information.

[0102] Based on the first location information collected, a first trajectory determined by multiple locations at different times can be obtained, and based on the second location information collected, a second trajectory determined by multiple locations at different times can be obtained.

[0103] In S403, when the similarity between the first trajectory and the second trajectory is greater than a predetermined similarity threshold, it is determined that the identifier of the inverter related to the first positioning information includes the identifier of the inverter corresponding to the second positioning information.

[0104] If the smart terminal and the inverter are on the same vehicle, the similarity between the smart terminal's first trajectory and the inverter's second trajectory should meet certain similarity requirements, such as a similarity greater than a predetermined similarity threshold. Therefore, the smart terminal on the same vehicle as the inverter can be determined based on the similarity threshold.

[0105] The determination that the similarity between the first trajectory and the second trajectory is greater than a predetermined similarity threshold may include the similarity of the shape of the trajectories and the similarity of the generation time of the trajectories.

[0106] The similarity of trajectory shapes is used to detect whether the inverter and the smart terminal follow the same movement path. If the similarity of trajectory shapes is greater than the shape similarity threshold, it means that the two movement trajectories correspond to the same route.

[0107] By comparing the similarity of their trajectory generation times, it can be determined whether the inverter and the smart terminal are on the same mode of transportation. This is because if there is a large gap between their generation times, it indicates that they may be on different modes of transportation along the same route.

[0108] By comparing the similarity of generation time and trajectory shape, smart terminals located near the inverter can be identified more accurately. In this case, the identifier of the inverter associated with the first location information can include the identifier of the inverter corresponding to the second location information.

[0109] In S304, the disconnection message is generated based on the identifier of the inverter associated with the first positioning information.

[0110] Based on the inverter's identifier related to the determined first location information, the smart terminal can generate a disconnection message, enabling it to quickly identify the inverter that needs data recovery.

[0111] In S202, based on the inverter identifier in the disconnection message, the name of the inverter corresponding to the identifier is searched in the Bluetooth device list of the smart terminal.

[0112] In this embodiment, the smart terminal can search for the inverter name, which includes the inverter identifier, in the Bluetooth device list. For example, the inverter identifier can be the same as the inverter name. The inverter identifier can be NBQ0001, NBQ0002, etc. When the inverter name in the Bluetooth device list is the same as the inverter identifier in the disconnection message, a request to establish a Bluetooth link can be sent to that inverter to establish a Bluetooth link between the smart terminal and the inverter.

[0113] In some possible implementations, since the transportation vehicle may have a large operating space, the distance between the inverter and the smart terminal may be relatively far, making it difficult to establish a reliable Bluetooth link. In this case, a third location information for the smart terminal on the transportation vehicle can be determined. This third location information is relative location information, which determines the smart terminal's position on the transportation vehicle. If the smart terminal is not within a pre-set location range, a prompt message can be generated to move it to that location.

[0114] For example, a smart terminal can use third-party positioning information, such as positioning base stations installed on a transportation vehicle, including Bluetooth positioning base stations, to determine the relative position of the smart terminal on the transportation vehicle.

[0115] Based on the inverter's installation location, the corresponding location range of the inverter can be predetermined. When the third-party location information of the smart terminal is not within this location range, the path information of the transportation vehicle, combined with the third-party location information of the smart terminal on the transportation vehicle, can be used to determine the path prompt information for moving to the location range. This allows the user to move to the location range where data recovery can be performed based on the path prompt information, and then search the Bluetooth list in the smart terminal to find the corresponding inverter name.

[0116] In S203, a Bluetooth link is established based on the inverter name in the Bluetooth device list, and the inverter's operating data is received and forwarded to the server through the Bluetooth link.

[0117] When the smart terminal is within the inverter's defined location range, the inverter's name can be found in the Bluetooth list. A Bluetooth link is established based on the inverter's name in the Bluetooth device list, and the operating data generated by the inverter, along with a small amount of cached operating data, can be received by the smart terminal. The smart terminal can temporarily store the received operating data when the mobile communication network's communication quality is unstable, or it can upload the received operating data via a satellite communication system. Alternatively, when the mobile communication network is stable, the smart terminal can also transmit the received operating data to a server.

[0118] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.
