[0071] In the following description, specific details such as specific system structures and technologies are proposed for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present application. However, those skilled in the art should clearly understand that the present application can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details from interfering with the description of the present application.

[0072] To illustrate the technical solution described in this application, the following will be described through specific embodiments.

[0073] As one of the important transportation tools for humans, the reliability and stability of the power system on a ship are very important for the safety and comfort of the ship. As a key device for power conversion, the inverter provides a stable and efficient power conversion solution for the ship. Therefore, it is particularly important to monitor the operation data of the inverter. By monitoring the operation parameters of the inverter, the operation status of the inverter can be effectively understood, and possible abnormal states can be discovered in a timely manner. When the inverter may have an abnormality, the inverter can be maintained in a timely manner to improve the reliability and stability of the operation of the power system.

[0074] However, the network environment in which a ship operates is usually relatively harsh. For example, the ship's navigation route may pass through uninhabited areas or areas far from land. If the network signal of the inverter is poor, the operation data of the inverter cannot be uploaded to the server. Since the cache space of the inverter is small, if the data cached by the inverter exceeds the cache space, the operation data of the inverter may be lost, which is not conducive to better monitoring the operation status of the inverter, may not be able to detect inverter abnormalities in a timely manner, and is not conducive to improving the stability and reliability of the inverter operation.

[0075] Figure 1 It is a schematic diagram of an implementation scenario of a data transmission method for an inverter provided in an embodiment of this application. In this implementation scenario, it includes an inverter 1, an intelligent terminal 2, and a server 3. The inverter 1 includes a first network 11 and a first Bluetooth module 12. The intelligent terminal 2 includes a second network 21 and a second Bluetooth module 22. Among them, when the inverter 1 can establish a communication connection with the server through the first network 11, the operation data of the inverter 1 can be uploaded to the server 3 through the first network 11 in the inverter 1. When the inverter 1 cannot establish a communication connection with the server through the first network 11, the intelligent terminal 2 can receive a disconnection message. The inverter can turn on the first Bluetooth module 12. The intelligent terminal 2 searches for the inverter name corresponding to the identifier of the inverter in the Bluetooth device list according to the identifier of the inverter 1 included in the disconnection message, establishes a Bluetooth link with the inverter 1 according to the inverter name and the second Bluetooth module 22, receives the operation data uploaded by the inverter, and uploads it to the server through the second network 21.

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

[0077] The second network 21 may include a mobile communication network and may also include a satellite communication network. When the inverter 1 fails to establish a communication connection with the server through the first network 11, the intelligent terminal 2 may establish a communication connection with the server 3 through the second network 21, or the intelligent terminal 2 caches the operation data in the storage space and transmits the operation data to the server 3 when the link of the second network 21 between the intelligent terminal 2 and the server 3 is normally connected.

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

[0079] Figure 2 The following is a schematic implementation flow diagram of a data transmission method for an inverter provided by an embodiment of the present application, which is described in detail as follows:

[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 the embodiment of the present application is a device that converts direct current into alternating current. By converting the direct current power supply into an alternating current power supply and controlling parameters such as output voltage, frequency, and current, the requirements of different electrical loads are met.

[0082] During the operation of the inverter, the inverter will send the operation data generated during the operation to the server through the first network. Among them, the operation data may include at least one of data such as DC input parameters, AC output parameters, conversion efficiency, environmental parameters, and power generation data. Among them, the DC input parameters may include at least one of parameters such as maximum input power, maximum input voltage operating voltage range, and maximum current. The AC output parameters may include at least one of parameters such as maximum output power, AC voltage, AC frequency, rated output power, rated output current, maximum output current, and power factor. The environmental parameters may include at least one of parameters such as operating temperature range and noise level. The power generation data may include at least one of parameters such as the power generation amount of the inverter and irradiation value.

[0083] The disconnection message in the embodiment of the present application is a message generated when the inverter fails to establish a communication link with the server through the first network. Since generally, the inverter establishes a communication link with the server through the first network, and the operation data is transmitted to the server through the communication link based on the first network. If the server cannot receive the operation data through the first network, it means that the inverter is disconnected, and a disconnection message can be generated. The disconnection message includes the identifier of the disconnected inverter, and the disconnected inverter can be uniquely determined through this identifier, so as to accurately rescue the operation data of the disconnected inverter.

[0084] In the embodiments of the present application, the disconnection message of the inverter is monitored by the intelligent terminal, and the disconnection message can be determined in various ways.

[0085] For example, the disconnection message can be sent to the intelligent terminal by the server. When the server detects that the communication link between the inverter and the server based on the first network is disconnected, or the server detects that the duration of not receiving the operation data of the inverter exceeds a predetermined duration threshold, it is determined that the communication link between the server and the inverter based on the first network is in a disconnected state. According to the second position information of the disconnected inverter, the relevant intelligent terminal can be determined, and a disconnection message is generated and sent to the relevant intelligent terminal.

[0086] In this case, the server generates a disconnection message according to the identifier of the inverter for which the operation data is not received, or according to the identifier of the inverter with the disconnected link.

[0087] In order to accurately send the disconnection message to the intelligent terminal that can perform data rescue, the server in the embodiments of the present application can also determine the intelligent terminal to which the disconnection message needs to be sent before sending the disconnection message.

[0088] For example, when the inverter is an inverter on a ship, it is necessary to determine that the distance between the intelligent terminal and the inverter is less than a predetermined distance threshold, or determine that the intelligent terminal is within the position range determined by the inverter. Then, the intelligent terminal that meets the distance condition or the position range condition is determined as the intelligent terminal to which the disconnection message needs to be sent. Among them, the position range determined by the inverter can be a position range determined by a predetermined radius range centered on the inverter.

[0089] The disconnection message in the embodiments of the present application can also be determined by the intelligent terminal when the communication link between the intelligent terminal and the server is in a disconnected state. The communication link between the intelligent terminal and the server is a communication link determined by the second network or a communication link determined by the mobile communication network. The specific process of determining the disconnection message is as Figure 3 shown, including:

[0090] In S301, monitor the communication link between the intelligent terminal and the server.

[0091] The intelligent terminal monitors the communication link between the server and the intelligent terminal, such as monitoring the mobile communication network between the server and the intelligent terminal.

[0092] When the inverter is a transportation vehicle such as a ship operating in a scenario with weak network signals, the communication quality of the smart terminal used by users on the transportation vehicle may be affected by the network signal. When the mobile communication network is normal, the smart terminal can establish a normal communication link with the server through the mobile communication network, and the smart terminal can receive the operating status of the inverter monitored and calculated by the server. When the mobile communication network is abnormal, such as in a disconnected state, the smart terminal cannot receive the data sent by the server, and the smart terminal can detect that the communication link is in a disconnected state.

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

[0094] In the embodiment of the present application, the inverter is usually located inside the device. Due to the obstruction of the wall or the device, the communication quality of the mobile communication network of the inverter is usually weaker than that of the mobile communication network of the smart terminal. Therefore, when the communication link between the smart terminal and the server is abnormal, such as in a disconnected state, it can usually be determined that the communication link between the inverter and the server is also in a disconnected state. At this time, the first positioning information of the smart terminal can be obtained to facilitate the generation of the identifier in the disconnection message.

[0095] For example, the first positioning information of the smart terminal can be determined through the satellite positioning signal of the smart terminal, including, for example, GPS positioning signal or Beidou satellite positioning information, or the position of the smart terminal can also be determined according to the environment where the smart terminal is located, such as by a positioning base station. The positioning base station can include, for example, a mobile communication positioning base station, etc.

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

[0097] To improve the rescue efficiency of the smart terminal, the embodiment of the present application can also determine the identifier of the inverter that needs to be rescued by the smart terminal that monitors the disconnection message, so that the smart terminal that monitors the disconnection message can quickly find the inverter that needs to rescue the operation data according to the identifier. When the inverter is an inverter on a transportation vehicle such as a ship, determining the identifier of the related inverter according to the first positioning information of the smart terminal can be as Figure 4 shown, including:

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

[0099] Among them, the first positioning information of the intelligent terminal can be determined by a mobile communication base station, or can also be determined by a satellite positioning system. The second positioning information of the inverter can be determined by a mobile communication base station. Since the mobile communication network of the inverter may be unstable, the second positioning information of the inverter can be obtained when the mobile communication network of the inverter is stable.

[0100] Among them, the first positioning information and the second positioning information can be in the same time period, such as the positioning information determined when the mobile communication network is stable.

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

[0102] Based on the collected first positioning information, a first trajectory determined by positioning at multiple different times can be obtained, and based on the collected second positioning information, a second trajectory determined by positioning at multiple 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 intelligent terminal and the inverter are on the same transportation vehicle, the similarity between the first trajectory of the intelligent terminal and the second trajectory of the inverter should be able to meet certain similarity requirements, such as the similarity being greater than a predetermined similarity threshold. Therefore, the intelligent terminal on the same transportation vehicle as the inverter can be determined according to the similarity threshold.

[0105] Among them, the determination that the similarity between the first trajectory and the second trajectory is greater than a predetermined similarity threshold can include the similarity of the shapes of the trajectories and the similarity of the generation times of the trajectories.

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

[0107] Through the similarity of the generation times of the trajectories, it can be determined whether the inverter and the intelligent terminal are on the same transportation vehicle. This is because if the interval between the generation times of the two is large, it means that they may be on different transportation vehicles on the same route.

[0108] By comparing the generation time similarity and the trajectory shape similarity, the intelligent terminal close to the inverter can be determined more accurately. In this case, the identifier of the inverter related to the first positioning information can include the identifier of the inverter corresponding to the second positioning information.

[0109] In S304, a disconnection message is generated according to the identifier of the inverter related to the first positioning information.

[0110] The intelligent terminal can generate a disconnection message according to the identifier of the inverter related to the determined first positioning information, so that the intelligent terminal can quickly determine the inverter that needs to perform operation data rescue according to the disconnection message.

[0111] In S202, according to the identifier of the inverter in the disconnection message, search for the name of the inverter corresponding to the identifier in the Bluetooth device list of the intelligent terminal.

[0112] In the embodiment of the present application, the intelligent terminal can find the name of the inverter including the inverter identifier in the Bluetooth device list. For example, the identifier of the inverter can be the same as the name of the inverter. The inverter identifier can be identifiers such as NBQ0001 and NBQ0002. When the name of the inverter in the Bluetooth device list is the same as the identifier of the inverter in the disconnection message, a request to establish a Bluetooth link can be sent to the inverter to establish a Bluetooth link between the intelligent terminal and the inverter.

[0113] In a possible implementation manner, since the transportation vehicle may have a large activity space, the distance between the inverter and the intelligent terminal may be relatively far, which is not conducive to establishing a reliable Bluetooth link. In this case, the third positioning information of the intelligent terminal on the transportation vehicle can be determined. The third positioning information is relative positioning information, that is, to determine the position of the intelligent terminal on the transportation vehicle. If the intelligent terminal does not belong to the preset position range, a prompt message to move to this position can be generated.

[0114] For example, the intelligent terminal can determine the third positioning information of the relative positioning of the intelligent terminal on the transportation vehicle through a positioning base station set on the transportation vehicle, including, for example, a Bluetooth positioning base station.

[0115] According to the installation position of the inverter, the corresponding position range of the inverter can be determined in advance. When the third positioning information of the intelligent terminal does not belong to this position range, the path prompt information to move to the position range can be determined according to the feasible path information of the transportation vehicle and the third positioning information of the intelligent terminal on the transportation vehicle, so that the user can move to the position range where data rescue can be performed according to the path prompt information and search for the name of the inverter corresponding to the identifier in the Bluetooth list of the intelligent terminal.

[0116] In S203, a Bluetooth link is established according to the name of the inverter in the Bluetooth device list, and the operation data of the inverter is received through the Bluetooth link and forwarded to the server.

[0117] When the intelligent terminal is within the position range determined by the inverter, the name of the inverter can be found in the Bluetooth list, and a Bluetooth link is established based on the name of the inverter in the Bluetooth device list. The operating data generated in the inverter and a small amount of cached operating data can be received by the intelligent terminal. When the communication quality of the mobile communication network is unstable, the intelligent terminal can temporarily store the received operating data, or upload the received operating data through the satellite communication system. Alternatively, when the mobile communication network is stable, the intelligent terminal can also transmit the received operating data to the server.

[0118] It should be understood that the magnitudes of the sequence numbers of the steps in the above embodiments do not imply the order of execution. The order of execution of each process should be determined by its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
