Description

Technical Field

[0001] The present invention relates to the field of ship communications, and in particular to a ship safety information intelligent interaction method based on a shipborne terminal. Background Art

[0002] In the existing means of ship-shore information exchange, the ship needs to report various navigation reports and other data on a daily basis, and the shore management may issue some instructions to the ship. Currently, there are mainly the following ways to exchange information between ships and shores:

[0003] The ship mainly uses the host PC network interface to exchange information with the shore platform through email, which makes the content of the interaction relatively simple. The various navigation reports that the ship needs to report daily are mostly paper versions, which are filled out manually, photographed, scanned, and then sent back to the shore platform via email. When the shore management personnel issue some temporary instructions that require the cooperation of the ship, the ship cannot accept and respond in a timely and transparent manner, affecting the efficiency of various ship and shore businesses.

[0004] In the offshore area, due to the limited coverage of cellular networks, mobile phone software and other means can be used to achieve the interaction of work content, pictures and other related information, which is limited to the area covered by the cellular network.

[0005] Satellite communication mainly includes satellite broadband communication and Beidou short message series communication under narrowband. However, there are many limitations based on satellite network communication, such as low communication frequency and high communication cost. In addition, it is not cost-effective to use satellite network communication in areas covered by cellular networks such as offshore areas.

[0006] Moreover, the existing ship-shore information interaction modes, cellular networks and satellite networks are all independent of each other, and the communication process cannot guarantee the optimal quality, efficiency and cost of communication. Summary of the invention

[0007] In order to solve the problems existing in the existing ship-shore information interaction, the present invention provides a method and system for intelligent interaction of ship safety information based on shipborne terminals. The ship-shore interaction information is standardized through a 4G communication module, a BeiDou-3 short message communication module and a satellite broadband network module. Finally, based on the signal strength of each communication module, intelligent switching of different communication networks is realized, so as to realize real-time, stable and efficient interaction of ship-shore information and reduce communication costs.

[0008] The technical objectives of the present invention are achieved through the following technical solutions:

[0009] A shipboard terminal-based intelligent interaction method for ship safety information includes a shipboard terminal and a mobile terminal, the shipboard terminal includes a shipboard automatic reporting device and a communication module, the communication module includes a 4G communication module, and the communication module is further integrated with a BeiDou-3 short message communication module and / or a satellite broadband network module on the basis of the 4G communication module; the mobile terminal and the shipboard terminal realize communication connection with a shore platform through the communication module; the mobile terminal connects to the shipboard terminal through a local area network to realize data interaction, and the mobile terminal realizes interaction with the shore platform through the communication module;

[0010] The shipborne automatic reporting device automatically generates a navigation report according to the ship's position and stores it in the local storage of the shipborne automatic reporting device; the shipborne automatic reporting device sends the navigation report to the shore platform through the communication module.

[0011] Furthermore, when the signal strength GSM of the 4G communication module is within a set threshold range, the communication connection between the mobile terminal, the ship-borne terminal and the shore platform is realized through the 4G communication module;

[0012] When the signal strength GSM of the 4G communication module exceeds the set threshold range, the communication module switches to the Beidou-3 short message communication module or the satellite broadband network module to realize the communication connection between the mobile terminal, the shipborne terminal and the shore platform.

[0013] Furthermore, the shipborne terminal also includes a signal strength detection module for detecting the signal strength of the 4G communication module. When the signal strength detection module detects the signal strength of the 4G communication module, it includes:

[0014] The signal strength detection module sends a signal strength detection instruction to the 4G communication module;

[0015] When the 4G communication module receives a signal strength detection instruction, it detects the GSM value of the signal strength of the current 4G communication module;

[0016] If the GSM value of the signal strength is between 0 and 25, the 4G communication module returns a signal strength compliance instruction to the signal strength detection module, and the shipboard terminal selects the 4G communication module to realize the communication connection between the mobile terminal, the shipboard terminal and the shore platform;

[0017] If the GSM value of the signal strength exceeds 0-25, the 4G communication module returns an instruction to the signal strength detection module that the signal strength does not meet the requirements. If the signal strength does not meet the requirements within the set time range, the shipborne terminal switches to the Beidou-3 short message communication module or the satellite broadband network module to realize the communication connection between the mobile terminal, the shipborne terminal and the shore platform.

[0018] Further, when the GSM value of the signal strength is 26-31 or 99, the 4G communication module returns an instruction that the signal strength does not meet the requirements to the signal strength detection module.

[0019] Furthermore, when the 4G communication module switches to the Beidou-3 short message communication module or the satellite broadband network module, if the signal strength of the Beidou-3 short message communication module is stronger than that of the satellite broadband network module, it switches to the Beidou-3 short message communication module, otherwise it switches to the satellite broadband network module.

[0020] Furthermore, the method also includes standardizing the data content of the communication between the mobile terminal, the ship-borne automatic reporting device and the shore platform, including:

[0021] When the shipboard terminal switches to the BeiDou-3 short message communication module for communication, the data is divided into navigation report, risk alarm information, ship-shore real-time interaction information and AIS data according to the content of the communication data, and the transmission priority is set in descending order;

[0022] When the shipborne terminal switches to the satellite broadband network module for communication, the data is divided into navigation reports, other reports, risk alarm information, AIS data, pictures, and videos according to the content of the communicated data, and a descending transmission priority is set, among which other reports are reports other than navigation reports.

[0023] Furthermore, when the shipboard terminal switches to the BeiDou-3 short message communication module for communication, the transmission frequency of navigation reports, risk alarm information and ship-shore real-time interaction information is 1 piece / min, and the transmission frequency of AIS data is 1 piece / 3min; the data size of each navigation report shall not exceed 1500B, the data size of each risk alarm information shall not exceed 200B, the data size of each ship-shore real-time interaction information shall not exceed 500B, and the data size of each AIS data shall not exceed 45B;

[0024] When the shipborne terminal switches to the satellite broadband network module for communication, the transmission frequency of navigation reports is 10 / day; the transmission frequency of other reports is 20 / day, the transmission frequency of risk alarm information is 1 / 20min, the transmission frequency of AIS data is 1 / 10min, the transmission frequency of pictures is 10 / day, and the transmission frequency of videos is 5 / day; the data size of each navigation report shall not exceed 1500B, the data size of each other report shall not exceed 300B, the data size of each risk alarm information shall not exceed 200B, the data size of each AIS data shall not exceed 45B, the data size of each picture shall not exceed 3000B, and the data size of each video shall not exceed 1M.

[0025] Furthermore, the method also includes filling in a navigation report or other report through a mobile terminal, including the following steps:

[0026] Mobile terminal generates report format template;

[0027] The user edits the report format template through the mobile terminal to generate a voyage report or other report and stores it in the local storage of the shipboard automatic reporting device;

[0028] The navigation report or other reports are sent to the shore platform through the communication module.

[0029] Furthermore, when the shipborne automatic reporting device generates a navigation report, the user reviews the navigation report through the mobile terminal and then sends it to the shore platform through the communication module.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. The present invention integrates a 4G communication module, a BeiDou-3 short message communication module and a satellite broadband network module through a ship-borne terminal, realizes switching of different communication modes based on the detection of the signal strength of the 4G communication module, realizes real-time, stable and efficient shore-ship information interaction, and avoids the long-term use of a communication mode with higher cost through flexible switching of the communication mode to reduce the communication cost.

[0032] 2. The present invention can automatically generate a navigation report through a ship-borne automatic reporting device, and can also realize manual filling of the navigation report through a mobile terminal, and can automatically generate a report format template to meet different application scenarios, improve the filling efficiency, and can achieve one-click sending after the filling is completed.

[0039] The technical solution of the present invention is further described below in conjunction with specific embodiments:

[0040] Example 1

[0041] A ship safety information intelligent interaction method based on a shipborne terminal includes a shipborne terminal and a mobile terminal. The shipborne terminal is a shipborne terminal host of a ship safety information intelligent interaction service platform. The shipborne terminal includes a shipborne automatic reporting device and a communication module. A 4G communication module is installed on the shipborne terminal host of the ship safety information intelligent interaction service platform. The communication module introduces a Beidou-3 short message communication module based on the 4G communication module. Figure 1 As shown, the 4G communication module is combined with the BeiDou-3 short message communication module to realize the communication connection between the mobile terminal, the ship-borne terminal and the shore platform; the mobile terminal is connected to the ship-borne terminal through the local area network to realize the data interaction between the mobile terminal and the ship-borne terminal, and the mobile terminal realizes the interaction with the shore platform through the communication module;

[0042] The shipborne automatic reporting device automatically generates a navigation report according to the ship's position and stores it in the local storage of the shipborne automatic reporting device; the shipborne automatic reporting device sends the navigation report to the shore platform through the communication module.

[0043] More specifically, Figure 1 As shown, a BeiDou-3 integrated machine 4 is added to the ship, and the BeiDou-3 integrated machine is connected to the ship-borne terminal 1 through the DB9RS232 serial port. The ship-borne terminal 1 processes data according to the BeiDou short message communication protocol, and a BeiDou command machine 5 is configured on the shore platform, so that ship-shore BeiDou short message data communication can be realized. The BeiDou-3 integrated machine 4 has a built-in IC BeiDou card, and the shore platform 2 receives data through an antenna, and the antenna is connected to the BeiDou command machine 5 by wire. The BeiDou command machine 5 is connected to the server of the shore platform 2 through a network port or a serial port, and the server of the shore platform 2 parses the BeiDou short message, thereby realizing BeiDou short message communication.

[0044] A 4G card 6 is configured in the mobile terminal, and data transmission with the shore platform 2 is realized through the shore base station 7.

[0045] When the signal strength GSM of the 4G communication module is within the set threshold range, the communication connection between the mobile terminal, shipborne terminal and shore platform is realized through the 4G communication module. If it exceeds the threshold range, the communication module is switched to the Beidou-3 short message communication module for communication.

[0046] In order to switch the 4G communication module to the BeiDou-3 short message communication module, a signal strength detection module is developed based on the shipborne terminal. The signal strength detection module sends a signal strength detection command to the 4G communication module at an interval of 3 seconds. The command is distinguished by the GSM standard, which is 0, 0-31 and 99. When GSM is 0, the signal strength is the strongest, when GSM is 99, there is no signal, when GSM is 0-31, the signal strength decreases, and 31 is the critical value and it can be considered that there is no signal. Based on this, it is judged whether the signal strength of the 4G communication module meets the strength of more than 20%, such as Figure 4 As shown, the specific process is as follows:

[0047] 1. The signal strength detection module sends a signal strength detection instruction to the 4G communication module;

[0048] When the 4G communication module receives a signal strength detection instruction, it detects the GSM value of the signal strength of the current 4G communication module;

[0049] If the GSM value of the signal strength is between 0 and 25 (including the end value 25), it is judged that there is a signal, and the 4G communication module returns an instruction that the signal strength meets the requirements to the signal strength detection module, and the shipboard terminal selects the 4G communication module to realize the communication connection between the mobile terminal, the shipboard terminal and the shore platform;

[0050] If the GSM value of the signal strength is 26-31 and 99, it is judged as no signal, and the 4G communication module returns the signal strength does not meet the requirements to the signal strength detection module. If the signal strength does not meet the requirements within the set time range, the shipboard terminal switches to the Beidou-3 short message communication module to achieve communication connection between the mobile terminal, the shipboard terminal and the shore platform. If the continuous time is set to 10 minutes, if the signal strength of the 4G communication module does not meet the requirements for 10 consecutive minutes, it switches to the Beidou-3 short message communication module for communication connection.

[0051] Example 2

[0052] A ship safety information intelligent interaction method based on a shipborne terminal includes a shipborne terminal and a mobile terminal. The shipborne terminal is a shipborne terminal host of a ship safety information intelligent interaction service platform. The shipborne terminal includes a shipborne automatic reporting device and a communication module. A 4G communication module is installed on the shipborne terminal host of the ship safety information intelligent interaction service platform. The communication module introduces a satellite broadband network module based on the 4G communication module, such as Figure 2 As shown, the 4G communication module is combined with the satellite broadband network module to realize the communication connection between the mobile terminal, the ship-borne terminal and the shore platform; the mobile terminal is connected to the ship-borne terminal through the local area network to realize the data interaction between the mobile terminal and the ship-borne terminal, and the mobile terminal realizes the interaction with the shore platform through the communication module;

[0053] The shipborne automatic reporting device automatically generates a navigation report according to the ship's position and stores it in the local storage of the shipborne automatic reporting device; the shipborne automatic reporting device sends the navigation report to the shore platform through the communication module.

[0054] When the 4G communication module switches to the satellite broadband network module, Figure 2 As shown, the shipborne terminal 1 accesses the satellite network through the shipborne satellite broadband network LAN / network cable, and specifically connects to the shipborne mobile communication antenna 3 through the LAN / network cable to realize data transmission with the communication satellite 8, and then sends it to the ground station 9 based on the communication satellite 8 and then to the public network, thereby realizing the sending of ship safety information to the shore platform 2.

[0055] When the 4G module switches to the satellite broadband network module, it is similar to the former, such as Figure 5 As shown, the details are as follows:

[0056] 1. The signal strength detection module sends a signal strength detection instruction to the 4G communication module;

[0057] When the 4G communication module receives a signal strength detection instruction, it detects the GSM value of the signal strength of the current 4G communication module;

[0058] If the GSM value of the signal strength is between 0 and 25 (including the end value 25), it is judged that there is a signal, and the 4G communication module returns an instruction that the signal strength meets the requirements to the signal strength detection module, and the shipboard terminal selects the 4G communication module to realize the communication connection between the mobile terminal, the shipboard terminal and the shore platform;

[0059] If the GSM value of the signal strength is 26-31 and 99, it is judged as no signal, and the 4G communication module returns the signal strength does not meet the requirements to the signal strength detection module. If the signal strength does not meet the requirements within the set time range, the shipboard terminal switches to the satellite broadband network module to achieve communication connection between the mobile terminal, the shipboard terminal and the shore platform. If the continuous time is set to 10 minutes, if the signal strength of the 4G communication module does not meet the requirements for 10 consecutive minutes, it switches to the satellite broadband network module for communication connection.

[0060] Example 3

[0061] A ship safety information intelligent interaction method based on a shipborne terminal includes a shipborne terminal and a mobile terminal. The shipborne terminal is a shipborne terminal host of a ship safety information intelligent interaction service platform. The shipborne terminal includes a shipborne automatic reporting device and a communication module. A 4G communication module is installed on the shipborne terminal host of the ship safety information intelligent interaction service platform. The communication module introduces a Beidou-3 short message communication module and a satellite broadband network module based on the 4G communication module. Figure 3As shown, the 4G communication module is combined with the BeiDou-3 short message communication module or the satellite broadband network module to realize the communication connection between the mobile terminal, the ship-borne terminal and the shore platform; the mobile terminal is connected to the ship-borne terminal through the local area network to realize the data interaction between the mobile terminal and the ship-borne terminal, and the mobile terminal realizes the interaction with the shore platform through the communication module;

[0062] The shipborne automatic reporting device automatically generates a navigation report according to the ship's position and stores it in the local storage of the shipborne automatic reporting device; the shipborne automatic reporting device sends the navigation report to the shore platform through the communication module.

[0063] When the 4G module switches to the BeiDou-3 short message communication module or satellite broadband network module, Figure 6 As shown, the details are as follows:

[0064] 1. The signal strength detection module sends a signal strength detection instruction to the 4G communication module;

[0065] When the 4G communication module receives a signal strength detection instruction, it detects the GSM value of the signal strength of the current 4G communication module;

[0066] If the GSM value of the signal strength is between 0 and 25 (including the end value 25), it is judged that there is a signal, and the 4G communication module returns an instruction that the signal strength meets the requirements to the signal strength detection module, and the shipboard terminal selects the 4G communication module to realize the communication connection between the mobile terminal, the shipboard terminal and the shore platform;

[0067] If the GSM value of the signal strength is 26-31 and 99, it is judged as no signal, and the 4G communication module returns the signal strength does not meet the requirements to the signal strength detection module. If the signal strength does not meet the requirements within the set time range, the shipboard terminal switches to the satellite broadband network module to achieve communication connection between the mobile terminal, the shipboard terminal and the shore platform. If the continuous time is set to 10 minutes, if the signal strength of the 4G communication module does not meet the requirements for 10 consecutive minutes, it switches to the Beidou-3 short message communication module or the satellite broadband network module for communication connection.

[0068] When switching, determine which of the Beidou-3 short message communication module and the satellite broadband network module has a stronger signal strength, and choose to switch to the communication module with stronger signal strength.

[0069] The shipborne automatic reporting device detects the ship's position and triggers the generation of a report when the area where the ship's position is located changes. The shipborne automatic reporting device extracts various parameters from the database and summarizes them in a set format to form a navigation report. In order to better understand the operation process of the shipborne automatic reporting device, this embodiment describes its operation process:

[0070] (1) The shipborne automatic reporting device is installed at the end of the ship (forward or stern) to determine whether the ship has entered the territorial waters of the People's Republic of China;

[0071] (2) If a vessel is about to enter the territorial waters of the People's Republic of China, the onboard automatic reporting device shall send out a report trapezoid and automatically generate the report content in the following format:

[0072] Ship name, call sign, IMO number and maritime mobile service identification code, format example: SPRING / DFPH2 / 9365788 / 218846000 / / ;

[0073] Report date, time and current position, example format: 202108 / 211450UTC / 2933N / 12312E / / ;

[0074] Name of the last port, departure date and time, example format: SINGAPORE / 202108 / 112150UTC / / ;

[0075] Name of the next port, expected arrival date and time, example format: SHANGHAI / 202108 / 251830UTC / / ;

[0076] Shipboard satellite telephone number, format example: 00870773156389 / / ;

[0077] The official name of the dangerous goods carried, the UN number (if no UN number, mark NA), the pollution category (if not applicable, mark NA), the loading quantity (tons), the format example: BENZENE / 1114 / Y / 50000 / / .

[0078] (3) After the navigation report is generated, it can be set to be sent directly to the shore platform through the communication module. The user can also review the navigation report through the mobile terminal and confirm it before sending it to the shore platform through the communication module.

[0079] (4) The shipboard automatic reporting device automatically stores detailed records of each report, which can be easily consulted and exported at any time.

[0080] The shipborne automatic reporting device can also automatically monitor whether the ship's automatic identification system equipment is in good use. The process is as follows:

[0081] (1) The automatic reporting device will automatically monitor whether the ship's automatic identification system equipment is in good working condition. If the ship's automatic identification system equipment cannot be used normally, the ship's driver will be reminded;

[0082] (2) According to the fault of the ship automatic identification system, the driver is reminded to send the ship position report every 2 hours in accordance with the reporting requirements, and the ship position report is automatically generated in the following format:

[0083] Ship name, call sign, IMO number and maritime mobile service identification code, format example: SPRING / DFPH2 / 9365788 / 218846000 / / ;

[0084] Report date, time and current position, format example: 202108 / 221108UTC / 3016N / 12303E / / ;

[0085] Estimated course and average speed, example format: COG296 / SOG125 / / .

[0086] (3) After the navigation report is generated, it is sent to the shore platform through the communication module.

[0087] (4) The shipboard automatic reporting device will automatically store detailed records of each report for easy reference and export at any time.

[0088] Since there are differences between the 4G cellular network protocol adopted by the 4G communication module, the Beidou short message protocol adopted by the Beidou-3 short message communication module, and the satellite communication protocol adopted by the satellite broadband network module, the method of the present invention also includes standardizing the data content of the communication between the mobile terminal, the ship-borne automatic reporting device and the shore platform, including:

[0089] When the shipboard terminal switches to the BeiDou-3 short message communication module for communication, the data is divided into navigation report, risk alarm information, ship-shore real-time interaction information and AIS data according to the content of the communication data, and the transmission priority is set in descending order;

[0090] When the shipborne terminal switches to the satellite broadband network module for communication, the data is divided into navigation reports, other reports, risk alarm information, AIS data, pictures, and videos according to the content of the communicated data, and a descending transmission priority is set, among which other reports are reports other than navigation reports.

[0091] Among them, when using 4G communication modules for communication, it is not limited by traffic and bandwidth, and the transmitted content is all standardized processed data, including: AIS data, instructions issued by the shore, and all text, images, videos and other attachments reported by the ship.

[0092] Among them, when using the BeiDou-3 short message communication module for communication, due to the limitation of transmission bytes of BeiDou short message communication, picture data can be transmitted, but it takes a relatively long time, 10-15 minutes for one picture, and video data cannot be sent. The highest level BeiDou card used in BeiDou-3 short message communication can achieve a single message of 1,000 Chinese characters and a transmission frequency of 1 message / min. Therefore, when switching to the BeiDou-3 short message communication module for communication, the content, data size and transmission frequency need to be limited, as shown in the following table (the highest priority is level 1):

[0093] Priority Transfer content Data caps Transmission frequency Level 1 Voyage Report 1500B 1 piece / min Level 2 Risk warning information 200B 1 piece / min Level 3 Real-time interactive information between ship and shore 500B 1 piece / min Level 4 AIS Data 45B 1 piece / 3min

[0094] Among them, when using satellite broadband network modules for communication, the information exchange between ship and shore is mainly limited by traffic, so the content of transmission is restricted according to different types and data sizes, as shown in the following table (the highest priority is level one):

[0095] Priority Transfer content Data caps Transmission frequency Level 1 Voyage Report 1500B 10 pieces / day Level 2 Other reports 300B 20 pieces / day Level 3 Risk warning information 200B 1 piece / 20min Level 4 AIS Data 45B 1 piece / 10min Level 5 picture 3000B 10 / day Level 6 video 1M 5 pieces / day

[0096] As a preferred solution, the navigation report or other report filling can be carried out through a mobile terminal, including the following steps:

[0097] Mobile terminal generates report format template;

[0098] The user edits the report format template through the mobile terminal to generate a voyage report or other report and stores it in the local storage of the shipboard automatic reporting device;

[0099] The navigation report or other reports are sent to the shore platform through the communication module.

[0100] Mobile terminals such as smart phones, tablet computers or interactive devices fixed on the hull can realize display and input operations through the mobile terminals.

[0101] The mobile terminal has a main display interface, which can display three parts of content: ship navigation status data overview and ship safety alarm information.

[0102] More specifically, the navigation status includes the ship name, real-time speed, heading, longitude and latitude of the ship position and data update time, and the navigation status can be obtained from the shipboard terminal.

[0103] The data overview includes alarm information within one day (24 hours), instructions issued by the shore, and the number of unprocessed and processed data reported by the ship. Interactive operations such as clicking on the interactive screen can jump to the unprocessed information section and the processed record section.

[0104] Ship safety alarm information includes alarm data such as abnormal turning, urgent encounter, dense ships, abnormal ship speed, abnormal wind speed, strangers, and unattended operation. Through interactive processing, the alarm information will no longer be displayed on the main display interface after processing is completed, and can be queried from the alarm record interface.

[0105] More specifically, the shore-side command is displayed on the main display interface, and personnel can see the command through the main display interface, and can also respond to the command through interactive input through the main display interface. The response can be achieved by taking photos, uploading pictures, documents, and videos.

[0106] More specifically, when reporting on the ship side, select the type to be reported, and the corresponding format template will pop up on the display main interface. The format template can be edited through interactive input, and one-click upload can be achieved after the reporting is completed. For example, after the navigation report and other reports are completed, in the case of network disconnection, the completed reports will form a reporting record and mark the reported processing type, and the time is the time of completion of the reporting; after the network is connected, the report will be resumed, the status will show that it has been reported and the time will be updated to the time of completion of the report.

[0107] This embodiment is only a further explanation of the present invention, not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed, but as long as it is within the scope of the claims of the present invention, it will be protected by the patent law.
