Description

TECHNICAL FIELD

[0001] The present application relates to the field of ship communication, in particular to an online control method for burning static information of ship AIS and an online control system for burning static information of ship AIS. BACKGROUND

[0002] AIS is the abbreviation of Automatic Identification System, which is composed of shore-based (base station) facilities and shipborne equipment, and is a digital navigation system and equipment integrating network technology, communication technology, computer technology and electronic display technology. At the same time, it can be connected with radar, ARPA, ECDIS, VTS, etc., to form a marine traffic control and monitoring network. Therefore, whether the nine-digit code, ship name and other static information of the shipborne terminal of AIS is correct will directly affect the safety of ship navigation and marine traffic control.

[0003] The ship MMSI nine-digit code is the unique identifier set in the ship AIS module, which plays an important role in ship navigation supervision. The relevant departments have issued a number of notices to prohibit users from modifying the static information of the ship at will. The existing management method is that the equipment manufacturer issues a burner to the distributor, and the distributor writes the static information including the ship MMSI nine-digit code into the equipment when selling the equipment. Since the burner is bound to a specific device, the equipment manufacturer cannot accurately match the devices that the burner is adapted to, which poses a management risk. Moreover, the distributor needs to frequently go to the ship for installation and static information setting during the sales process, which increases the overall cost in the sales process. SUMMARY

[0004] The purpose of the present application is to provide an online control method and system for burning static information of ship AIS to solve the problems that the static information of the ship cannot be unified and cannot be controlled and managed remotely in real time, and the static information of the ship is difficult to change legally in the prior art.

[0005] To achieve the above purpose, the present application adopts the following technical solutions:

[0006] The present application discloses an online control method for burning static information of ship AIS, which comprises the following processes:

[0007] The ship terminal initiates an online static information burning request and directly sends the unique code of the ship, the static information to be modified and the identity authentication certificate to the server, or sends the unique code of the ship, the static information to be modified and the identity authentication certificate to the server through the mobile terminal.

[0008] The ship terminal receives the feedback information of the service end after the authentication of the online burning request of the static information, if the feedback information is the authentication failure, the ship terminal does not update the static information, if the feedback information is the authentication success, the ship terminal receives the encryption key and the updated static information sent by the service end, and the ship terminal uses the encryption key to unlock and burns the static information of the AIS.

[0009] Further, the specific steps of sending data to the service end by the mobile end are as follows:

[0010] (1). The ship terminal generates a two-dimensional code by taking the unique code as a parameter; the unique code is the machine number or / and MMSI code of the ship terminal.

[0011] (2). Code scanning and analysis, the mobile end scans the two-dimensional code to obtain the unique code.

[0012] (3). The mobile end sends the unique code to the service end to request the service end to query the current static information of the ship terminal.

[0013] (4). The mobile end receives the current static information obtained by the service end and displays it on the mobile end interface.

[0014] (5). Fill in the static information to be modified and upload the identity authentication certificate on the mobile end, and send the data to the service end.

[0015] In another embodiment, the specific steps of sending data to the service end by the mobile end are as follows:

[0016] (1). The ship terminal generates a two-dimensional code by taking the unique code as a parameter; the unique code is the machine number or / and MMSI code of the ship terminal.

[0017] (2). Code scanning and analysis, the mobile end scans the two-dimensional code to obtain the unique code.

[0018] (3). Fill in the static information to be modified and upload the identity authentication certificate on the mobile end, and send the data to the service end.

[0019] Further, if the authentication fails, the ship terminal does not update the static information, and sends the reason for the authentication failure to the mobile end; if the authentication succeeds, the ship terminal updates the static information and destroys the encryption key.

[0020] The static information includes MMSI code, English ship name, Chinese ship name, ship type, ship length, ship width, call sign, IMO, draft, total tonnage, year of construction, and position of antenna, the identity authentication certificate is obtained by collecting images through the camera of the mobile end, and the camera of the mobile end adds watermark to the images after collecting the images.

[0021] Preferably, the identity authentication certificate includes a registry certificate and an Automatic Identification System (AIS) identification code certificate, and the method for the server to authenticate the online burning request of static information is as follows: the identity of the ship is authenticated according to the registry certificate and the Automatic Identification System (AIS) identification code certificate. The authentication method is as follows: the ship name and the ship identification number are read from the registry certificate, the ship name, the ship identification number and the MMSI code are read from the Automatic Identification System (AIS) identification code certificate, the ship name and the MMSI code are read from the information submitted by the user, and the three are compared. If the data is consistent, the identity authentication is passed, otherwise, the identity authentication is not passed.

[0022] Further, the reading of the registry certificate and the Automatic Identification System (AIS) identification code certificate when authenticating the identity of the ship is realized by the following algorithm: a1.

Extract the text information and the text coordinates from the image; a3. Align the text information according to the coordinate information; a4. Combine the text with similar distances to form a text block; a5. Match and determine the pair of fields and values according to the size and coordinate relationship of the text box; a6.

At least "ship name" and "ship identification number" need to be identified from the registry certificate, and at least "ship name", "ship identification number" and "MMSI code" need to be identified from the Automatic Identification System (AIS) identification code certificate.

[0023] Preferably, when the identity authentication is passed, the server stores the static information of the authenticated ship into the ship information database, updates the association between the ship information database and the equipment information database according to the unique code, and takes out the encryption key corresponding to the ship terminal. The server generates feedback information according to the authentication result, and packs and sends the feedback information, the encryption key and the updated static information to the ship terminal. When the identity authentication is not passed, the server generates feedback information with the reason for the authentication failure according to the authentication result, and sends the feedback information to the ship terminal.

[0025] The algorithm for scanning and analyzing the two-dimensional code in step (2) is as follows: c1. separating the timestamp from the two-dimensional code, if the time difference between the time indicated by the timestamp and the scanning and analyzing time exceeds the pre-set time range, the analysis is not performed and the result is fed back to the mobile terminal; if the time difference between the time indicated by the timestamp and the scanning and analyzing time is within the pre-set time range, steps c2-c5 are performed.

[0026] c2. separating the data code and the error correction code from the two-dimensional code; c3. reading the final carrier information bit string from the error correction code; c4. taking the exclusive OR of the data code and the final carrier information bit string to obtain the grouping data embedding position of the ship information bit string in the final carrier information bit string; and c5. extracting the ship information bit string according to the obtained grouping data embedding position.

[0040] In order for those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below in combination with the drawings and specific embodiments.

[0041] Embodiment One

[0042] As Figure 1 shown, the embodiment discloses an online control system for burning and writing ship AIS static information, which comprises a ship terminal and a server. The ship terminal is provided with a serial number.

[0043] The ship terminal comprises an AIS module, a CPU processing module, a burning and writing encryption module, a first network communication module and a data storage module.

[0044] The AIS module stores ship static information. The CPU processing module is used for reading data of the AIS module and writing data into the AIS module. The burning and writing encryption module is used for locking the ship static information when the CPU processing module writes data into the AIS module, and only allows writing data when the CPU provides a decryption key. The first network communication module is connected with the CPU processing module and is used for connecting the CPU processing module to the Internet. The data storage module is used for storing data.

[0045] The server comprises a database, a second network communication module and an identity verification module. The database comprises a device information database, a ship information database and a key information database. The device information database stores device information with the serial number of the ship terminal as the primary key. The ship information database stores ship information with the MMSI code of the ship as the primary key. The key database is used for storing the decryption key of the AIS module. The second network communication module is used for connecting to the Internet. The identity verification module is used for performing identity authentication on the ship. If the identity authentication is passed, the ship static information in the database is updated, the encrypted key corresponding to the serial number of the ship terminal is taken out from the database together with the updated static information, and the corresponding ship terminal is sent by the second network communication module.

[0046] In the embodiment, the online control method for burning and writing ship AIS static information by using the above system comprises the following processes:

[0047] S1. The ship terminal initiates a request for online burning of static information, and sends the unique code of the ship, the static information to be modified, and the identity authentication certificate to the server. The identity authentication certificate includes the certificate of registry and the certificate of the automatic identification system (AIS) identification code.

[0048] Before the request for burning is initiated, the data of the AIS module is locked by the burning encryption module, and the CPU processing module cannot modify the data of the AIS module. When there is a special situation, the data of the AIS module needs to be changed, at which time the ship administrator inputs the static information of the ship to be modified into the CPU processing module, and the CPU processing module sends the data to the server through the first network communication module.

[0049] S2. The ship terminal receives the feedback and completes the burning.

[0050] In this process, the method for the server to authenticate the request for online burning of static information is as follows: the identity of the ship is authenticated by the identity verification module according to the certificate of registry and the certificate of the automatic identification system (AIS) identification code. As shown in Figure 3 , specifically: the ship name and the ship identification number are read from the certificate of registry, the ship name, the ship identification number, and the MMSI code are read from the certificate of the automatic identification system (AIS) identification code, and the ship name and the MMSI code are read from the form information submitted by the user. The three are compared, and if the data is consistent, the identity authentication is passed, otherwise, the identity authentication is not passed.

[0051] The server sends feedback information to the ship terminal through the second network communication module, and if the authentication is successful, the encryption key and the updated static information are also sent.

[0052] After receiving the feedback information, if the feedback information is authentication failure, the CPU processing module of the ship terminal does not update the static information, at which time the burning encryption module still locks the static information of the ship, and the CPU processing module cannot perform burning. If the feedback information is authentication success, the encryption key and the updated static information sent by the server are also received. The ship terminal uses the encryption key to unlock the burning encryption module, and the CPU processing module burns the static information of the AIS, thereby completing the online update of the static information of the AIS.

[0053] Embodiment Two

[0054] As shown in Figure 2 , the embodiment discloses an online control system for burning of static information of a ship AIS, which comprises a ship terminal, a mobile terminal, and a server. The ship terminal is provided with a machine number.

[0055] The ship terminal comprises an AIS module, a CPU processing module, a burning encryption module, a first network communication module, a two-dimensional code generation module and a data storage module.

[0056] The AIS module stores ship static information. The CPU processing module is used for reading data of the AIS module and writing data into the AIS module. The burning encryption module is used for locking the ship static information when the CPU processing module writes data into the AIS module, and only allows writing data when the CPU provides a decryption key. The first network communication module is connected with the CPU processing module and is used for connecting the CPU processing module to the Internet. The two-dimensional code generation module is used for generating a two-dimensional code by taking the unique code of the ship as a parameter. The data storage module is used for storing data.

[0057] The mobile terminal comprises an image acquisition module, a two-dimensional code analysis module and a form module. The mobile terminal can be a tablet computer or a mobile phone. The image acquisition module is a camera and is used for scanning a two-dimensional code and acquiring an image. The two-dimensional code analysis module is used for analyzing the two-dimensional code to obtain the unique code of the ship. The unique code of the ship can be the serial number of the ship terminal or / and the MMSI code.

[0058] The server comprises a database, a second network communication module and an identity verification module. The database comprises a device information database, a ship information database and a key information database. The device information database stores device information by taking the serial number of the ship terminal as a primary key. The ship information database stores ship information by taking the MMSI code of the ship as a primary key. The key database is used for storing the decryption key of the AIS module. The second network communication module is used for connecting to the Internet. The identity verification module is used for performing identity authentication on the ship. If the identity authentication is passed, the ship static information in the database is updated, the encrypted key corresponding to the serial number of the ship terminal is taken out from the database together with the updated static information, and the updated static information is sent to the corresponding ship terminal through the second network communication module.

[0059] The embodiment discloses an online control method for burning ship AIS static information. The system of the embodiment comprises the following steps:

[0060] S1. Initiating an online burning request

[0061] The ship terminal initiates an online burning request for ship static information. The two-dimensional code generation module generates a two-dimensional code by taking the unique code of the ship as a parameter. The two-dimensional code is refreshed once in a period of time, for example, once in 10 minutes. The unique code of the ship can be the serial number of the ship terminal or / and the MMSI code.

[0062] The generation of the two-dimensional code is realized by the following algorithm:

[0063] b1. convert the unique code of the ship and the current time stamp into a ship information bit string.

[0064] b2. determine the final carrier information embedding packet length according to the pre-selected QR code error correction level.

[0065] b3. determine the number of copies of the basic carrier information bit string based on the final carrier information embedding packet length, the number of basic carrier information bit string packets, and the number of ship information bit string packets.

[0066] b4. copy the basic carrier information bit string according to the number of copies to obtain the final carrier information bit string.

[0067] b5. select a carrier QR code according to the symbol capacity of the QR code under the pre-selected QR code error correction level.

[0068] b6. calculate the error correction code when writing the final carrier information bit string as the information using the two-dimensional code error correction algorithm.

[0069] b7. embed the ship information bit string into the final carrier information bit string using the SNE algorithm to obtain the data code of the two-dimensional code.

[0070] b8. embed the data code and the error correction code into the carrier QR code to obtain the two-dimensional code.

[0071] S2. Scan and analyze

[0072] The mobile terminal is generally a mobile phone, which is provided with a camera and installed with an APP, and the APP is provided with a two-dimensional code analysis module. The unique code of the ship is obtained by scanning the two-dimensional code generated in step S1 through the two-dimensional code analysis module of the mobile phone APP.

[0073] The algorithm for scanning and analyzing the two-dimensional code is as follows:

[0074] c1. separate the time stamp from the two-dimensional code, if the time difference between the time indicated by the time stamp and the scanning and analyzing time exceeds the pre-set time range (such as 10 minutes), do not analyze, and feedback the result to the mobile terminal. The mobile terminal receives the feedback result, the user needs to refresh the two-dimensional code, and then re-scan and analyze the two-dimensional code.

[0075] If the time difference between the time indicated by the time stamp and the scanning and analyzing time exceeds the pre-set time range, the following steps c2-c5 are continued.

[0076] c2. separate the data code and the error correction code from the two-dimensional code.

[0077] c3. read the final carrier information bit string from the error correction code.

[0078] c4. Taking the data code and the final carrier information bit string XOR, obtaining the grouping data embedding position of the ship information bit string in the final carrier information bit string.

[0079] c5. Extracting the ship information bit string according to the obtained grouping data embedding position, to obtain the unique code of the ship.

[0080] S3. The mobile terminal sends the unique code to the server, and requests the server to query the current static information of the ship terminal. The static information includes MMSI, English ship name, Chinese ship name, ship type, ship length, ship width, call sign, IMO, draft, gross tonnage, year of construction, positioning antenna position and other information.

[0081] S4. The server queries the current static information of the ship according to the unique code, and sends it to the mobile terminal. The mobile terminal receives the current static information queried by the server, and displays it on the interface of the mobile terminal, as shown in Figure 4 .

[0082] S5. The user modifies the static information on the interface of the mobile terminal and uploads the certificate of registry ( Figure 5 shown as “ship register / certificate of ship nationality”) and the certificate of AIS identification code ( Figure 5 shown as “certificate of AIS identification code”). The certificate of registry refers to the collective name of various documents on the ship to prove the ownership of the ship and its technical operation performance, which in practice includes: certificate of ship nationality (cargo ship), certificate of ship inspection (fishing boat), ship register (cargo ship), ship plaque register (fishing boat) and the like. The certificate of registry and the certificate of AIS identification code are obtained by collecting images through the camera of the mobile phone. In this embodiment, a watermark is added to the image after the image is collected, to prevent the image from being modified.

[0083] After filling in and uploading, click Submit Authentication, and the mobile terminal will package the data and send it to the server.

[0084] S6. Receive feedback information and complete burning

[0085] The ship terminal receives the feedback information after the server authenticates the online burning request of the static information.

[0086] The method for the server to authenticate the online burning request of the static information is: authenticating the identity of the ship according to the certificate of registry and the certificate of AIS identification code. As shown in Figure 3 , specifically: reading the ship name and ship identification number from the certificate of registry, reading the ship name, ship identification number and MMSI code from the certificate of AIS identification code, and reading the ship name and MMSI code from the form information submitted by the user, comparing the three, and if the data is consistent, the identity authentication is passed, otherwise, the identity authentication is not passed.

[0087] The reading of the certificate of registry and the certificate of the automatic identification system (AIS) identification code when authenticating the ship identity is realized by the following algorithm:

[0088] a1. Obtain the image data of the certificate of registry and the certificate of the automatic identification system (AIS) identification code.

[0089] a2. Extract the text information and the text coordinates from the image.

[0090] a3. Align the text information according to the coordinate information.

[0091] a4. Merge the text with similar distances to form a text block.

[0092] a5. Match and determine the fields and values according to the size and coordinate relationship of the text box.

[0093] a6. Identify the text block content as the "field", match the key name in the database, and save the corresponding value as the value of the corresponding key name. At least, the certificate of registry needs to identify and obtain "ship name" and "ship identification number"; the certificate of the automatic identification system (AIS) identification code needs to identify and obtain "ship name", "ship identification number" and "MMSI code".

[0094] When the identity authentication fails, the server generates feedback information with the reason for the authentication failure according to the authentication result, and sends the feedback information to the ship terminal. Upon receiving the feedback information of the authentication failure, the ship terminal does not update the static information, and sends the reason for the authentication failure to the mobile phone, so as to facilitate the user to check the reason for the failure.

[0095] When the identity authentication is passed, the server stores the static information of the ship passed by the authentication into the ship information database, updates the association relationship between the ship information database and the equipment information database according to the machine number of the ship terminal, and takes out the encryption key of the AIS module of the corresponding ship terminal according to the machine number. The server generates feedback information according to the authentication result, and packs and sends the feedback information, the encryption key and the updated static information to the ship terminal. Upon receiving the feedback information of the successful authentication, the ship terminal receives the encryption key and the updated static information sent by the server, uses the encryption key to unlock and write the encryption module, updates the static information of the AIS module, and destroys the encryption key after the update is completed.

[0112] S3. The mobile terminal displays the analyzed current static information on the interface of the mobile terminal, as shown in Figure 4 S4. The user modifies the static information on the interface of the mobile terminal and uploads the registry certificate, as shown in

[0113] Figure 5 S4. The user modifies the static information on the interface of the mobile terminal and uploads the registry certificate, as shown inAs shown, the ship registration certificate and the ship automatic identification system (AIS) identification code certificate are obtained by collecting images through the camera of the mobile phone. After filling and uploading are completed, click on the submit authentication, and the mobile terminal will package the data and send it to the server.

[0114] S5. Receiving feedback information to complete the burning

[0115] The method for the server to authenticate the online burning request of the static information is: according to the ship registration certificate and the ship automatic identification system (AIS) identification code certificate, authenticate the ship identity. The specific method of identity authentication is the same as in Embodiment Two.

[0116] When the identity authentication fails, the server generates feedback information with the reason for the authentication failure according to the authentication result, and sends the feedback information to the ship terminal. Upon receiving the feedback information of the authentication failure, the ship terminal does not update the static information, and at the same time, sends the reason for the authentication failure to the mobile phone, so as to facilitate the user to check the reason for the failure.

[0117] When the identity authentication is passed, the server stores the static information of the authenticated ship into the ship information database, and updates the association between the ship information database and the equipment information database according to the mobile number of the ship terminal, and takes out the encryption key of the AIS module of the corresponding ship terminal according to the mobile number. The server generates feedback information according to the authentication result, and packages the feedback information, the encryption key and the updated static information and sends them to the ship terminal. Upon receiving the feedback information of the successful authentication, the ship terminal receives the encryption key and the updated static information sent by the server, uses the encryption key to unlock the burning encryption module, and updates the static information of the AIS module, and after the update is completed, destroys the encryption key.

[0118] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
