Description

Technical Field

[0001] The present invention relates to the field of ship communication, and particularly to a method for supervising ships with a plug-in AIS system. Background Art

[0002] AIS is the abbreviation of Automatic Identification System for Ships, which is jointly composed of shore-based (base station) facilities and on-board equipment. It is a digital navigation aid system and equipment integrating network technology, communication technology, computer technology, and electronic display technology. For the on-board terminal based on AIS communication, the correctness of static information such as the nine-digit code and ship name of the AIS system will directly affect the navigation safety and management and dispatching of ships. The static information such as the nine-digit code and ship name of the traditional AIS system is generally solidified and written through the interface of the device by using the manufacturer's coding software, and the operation is completed by the service provider or the designated service point. Due to the difficulty in controlling the erasing and writing of static information, the random migration and installation of equipment, and the users can easily evade supervision by means such as stopping the AIS work through simple operations, it is easy to cause scrambled code phenomena such as number plate duplication and inconsistent ship codes; the modification and change of ship information cannot be controlled and grasped in real time, and it is difficult to ensure "one ship, one code, one device".

[0003] In view of this, the inventor of the present invention has conducted in-depth research on the above problems, and thus this case is generated. Summary of the Invention

[0004] The purpose of the present invention is to provide a method for supervising ships with a plug-in AIS system to solve the problems of scrambled codes caused by the arbitrary modification of static information and the inability of the management center to supervise in real time in the prior art.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A method for supervising ships with a plug-in AIS system is completed through the following steps:

[0007] Step 1, the on-board AIS terminal equipment is registered for network access. The enterprise manufacturer registers and files the product catalog information of the on-board AIS terminal equipment produced by itself on the ship management platform to obtain a registered terminal. The on-board AIS terminal equipment has a SIM card reading device;

[0008] Step 2, the AIS card is registered and filed. An ID code is generated for each AIS card and a write key is set to obtain a registered card;

[0009] Step 3: Initial registration of the AIS card. The applicant for the card goes to the local ship management agency to apply for the card. The card-making personnel of the local ship management agency select the filing card from Step 2, search for the ship information on the ship management platform based on the ship name and the information of the shipowner provided by the applicant for the card. After verifying the information, the ship management platform generates a nine-digit code, a read key, and a transmission key for the ship and the selected filing card, and writes the static ship data such as the ship code, ship name, shipowner, ship type, captain, ship width, and molded depth into the filing card through the write key of the filing card to complete the initial registration and filing of the AIS card, and obtain the initialized AIS card.

[0010] Step 3: Interface docking. Insert the initialized AIS card from Step 3 into the AIS on-board terminal device. The AIS on-board terminal device issues a card insertion and registration instruction and sends the ID code of the AIS card, the ID code of the AIS on-board terminal device, and the product catalog information of the AIS on-board terminal device to the ship management platform. After obtaining the data, the ship management platform verifies whether the AIS card is the filing card from Step 2 and whether the AIS on-board terminal device is the filing terminal from Step 1. If the conditions are met, it sends a registration success instruction to the AIS on-board terminal device to complete the combination of the AIS card and the AIS on-board terminal device.

[0011] Step 4: Data acquisition. The AIS on-board terminal device that has completed Step 3 applies to the ship management platform for the read key and transmission key of the AIS card. The AIS on-board terminal device analyzes the read key through the transmission key and uses the read key to read the current static ship data. After the AIS on-board terminal device reads the current static ship data, it sends a read feedback instruction to the ship management platform. After receiving the read feedback instruction, the ship management platform sends a reception success instruction to the AIS on-board terminal device to complete the interaction among the AIS card, the AIS on-board terminal device, and the ship management platform.

[0012] In the above Step 1, the product catalog information of the AIS on-board terminal device includes the product name, product trademark, manufacturer, equipment number, equipment model, operating frequency, equipment type, and product certificate number and validity period.

[0013] After Step 4, when the AIS card is removed, the AIS on-board terminal device sends a card removal instruction to the ship management platform, and the ship management platform notifies the ship management platform managers and ship managers in the form of text messages.

[0014] After Step 4, when the AIS card is damaged, lost, or the fishing boat information in the AIS card changes, the ship management platform cancels the AIS card and sends the cancellation information to the AIS on-board terminal device. The AIS on-board terminal device clears the card reading information, and the original AIS card becomes invalid when inserted.

[0015] The AIS on-board terminal device has a housing and a circuit board installed inside the housing. The housing has a top shell with a hollow structure with an open bottom surface and a bottom shell with a hollow structure with an open top surface. The top shell and the bottom shell are locked together. The circuit board is installed on the bottom shell. The SIM card reader device is integrated on the bottom surface of the circuit board. The SIM card reader device has a card slot. A window is opened on the lower bottom surface of the bottom shell corresponding to the card slot. An installation bracket for propping up the bottom shell is installed on the bottom shell. An anti-tampering block that extends into the window and is hidden inside the installation bracket is detachably installed on the installation bracket.

[0016] A magnetic induction sensor is installed on the bottom shell at the window. A magnetic block is installed on the anti-tampering block.

[0017] An alarm button is installed on the bottom shell opposite to the anti-tampering block. The top surface of the anti-tampering block presses against the alarm button.

[0018] The installation bracket has an upper top piece and L-shaped pieces on both sides of the upper top piece. The L-shaped pieces have a vertical part and a horizontal part. One end of the vertical part is integrally formed and connected to the side wall of the upper top piece. The other end of the vertical part is perpendicular to the horizontal part. The two vertical parts are between the two horizontal parts. The upper top piece is in close contact with and locked to the bottom surface of the bottom shell. A through hole that penetrates up and down is opened on the horizontal part. A protective cover with an open top surface is stacked on the horizontal part at the through hole. A locking screw that passes through the protective cover and the through hole is provided inside the protective cover. A sealing cover is embedded on the open end of the protective cover.

[0019] An installation hole that penetrates up and down is installed on the upper top piece. The anti-tampering block is erected. The upper end of the anti-tampering block passes through the installation hole to the exposed window. The lower part of the anti-tampering block is below the upper top piece. An installation ring protrudes outward from the lower end of the anti-tampering block. A locking screw is installed on the installation ring.

[0020] In a ship supervision method of a plug-in card type AIS system according to the present invention, ship static information can only be obtained by reading the card. The operator cannot arbitrarily erase, rewrite, or tamper with the AIS position code on the AIS on-board terminal device, enabling the management platform to effectively control the nine-digit AIS code of the ship, truly achieving one ship, one code, and one device, effectively avoiding the chaotic code phenomena such as inconsistent ship codes, one ship with multiple codes, or one code with multiple ships, which is beneficial to the supervision of the management department.

[0023] A method for supervising ships of an insert - card type AIS system of the present invention, a method for supervising ships of an insert - card type AIS system, is completed through the following steps:

[0024] Step 1, network registration of the AIS on - board terminal device. The enterprise manufacturer registers the product catalog information of the AIS on - board terminal device produced by itself on the ship management platform for record - filing, obtaining a recorded terminal. The AIS on - board terminal device has a SIM card reading device. The product catalog information of the AIS on - board terminal device includes detailed product information such as product name, product trademark, manufacturer, equipment number, equipment model, operating frequency, equipment type, product certificate number and validity period, etc.

[0025] Step 2, record - filing of the AIS card. Generate an ID code for each AIS card and set a write key to obtain a recorded card.

[0026] Step 3, initial registration of the AIS card. The card - applying personnel go to the local ship management agency to apply for a card. The card - making personnel of the local ship management agency select the recorded card in Step 2, search for the ship information on the ship management platform through the ship name and the information of the ship owner provided by the card - applying personnel. After verifying the information, the ship management platform generates a nine - digit code, a read key and a transmission key for the ship and the selected recorded card, and writes the ship static data such as ship code, ship name, ship owner, ship type, ship length, ship width and molded depth into the recorded card through the write key of the recorded card, completing the initial registration and record - filing of the AIS card to obtain an initialized AIS card.

[0027] Step 3, interface docking. Insert the initialized AIS card in Step 3 into the AIS on - board terminal device. The AIS on - board terminal device issues an insert - card registration instruction and sends the ID code of the AIS card, the ID code of the AIS on - board terminal device and the product catalog information of the AIS on - board terminal device to the ship management platform. After obtaining the data, the ship management platform verifies whether the AIS card is the recorded card in Step 2 and whether the AIS on - board terminal device is the recorded terminal in Step 1. If the conditions are met, it sends a registration success instruction to the AIS on - board terminal device to complete the combination of the AIS card and the AIS on - board terminal device.

[0028] Step 4, data acquisition. The AIS on - board terminal device that has completed Step 3 applies to the ship management platform for the read key and transmission key of the AIS card. The AIS on - board terminal device analyzes the read key through the transmission key and uses the read key to read the current ship static data. After the AIS on - board terminal device reads the current ship static data, it sends a read - feedback instruction to the ship management platform. After receiving the read - feedback instruction, the ship management platform sends a reception success instruction to the AIS on - board terminal device to complete the interaction among the AIS card, the AIS on - board terminal device and the ship management platform.

[0029] The present invention discloses a ship supervision method of a card-insertion AIS system. The static information of the ship can only be obtained by reading the card. The operator cannot arbitrarily erase or tamper with the AIS sending code on the AIS ship-borne terminal device, so that the management platform can effectively control the AIS nine-digit code of the ship, truly achieving one ship, one code, and one device, effectively avoiding the phenomenon of inconsistent ship codes, multiple codes for one ship, or multiple codes for one code, and effectively ensuring the supervision of the management department.

[0030] In the present invention, the ship management platform has an enterprise end and a management end. The enterprise end is used for enterprise directory and product network registration. The enterprise logs in to the ship management platform through a registered account and registers the AIS shipborne terminal equipment. The enterprise end has product information entry functions, product information addition, deletion, query and other information maintenance functions and data import and export functions; the management end is used by local ship management personnel and has AIS card registration, filing, reading, change and alarm functions.

[0031] According to the ship supervision method of the card-insertion AIS system of the present invention, after step 4, when the AIS card is removed, the AIS ship-borne terminal device sends a card removal instruction to the ship management platform, and the ship management platform notifies the ship management platform manager and the ship manager in the form of a text message.

[0032] Accordingly, when the AIS card is damaged, lost, or the fishing vessel information in the AIS card is changed, the ship management platform cancels the AIS card and sends the cancellation information to the AIS shipborne terminal device. The AIS shipborne terminal device clears the card reading information and the original AIS card becomes invalid.

[0033] In the present invention, Figure 1 , 2 As shown, the AIS shipborne terminal device comprises a housing 1 and a circuit board (not shown) installed in the housing. The circuit board comprises a processor required for the AIS shipborne terminal device. The housing 1 comprises a top housing 11 with a hollow structure having an open bottom surface and a bottom housing 12 with a hollow structure having an open top surface. The top housing 11 and the bottom housing 12 are fixed together by screws. The circuit board is flatly installed in the bottom housing 12. The SIM card reader is integrated on the circuit board and has a card slot. The SIM card reader is a well-known product and will not be described here. The bottom housing 12 is provided with a The mounting bracket 2 has an anti-dismantling block 3 which is removably installed and extends into the window and is hidden in the mounting bracket. The bottom shell 12 is provided with a magnetic induction sensor at the window. A magnetic block is installed on the top surface of the anti-dismantling block 3. The output end of the magnetic induction sensor is electrically connected to the input end of the processor on the circuit board. This electrical connection method is well known. When used, if the shell is separated from the mounting bracket, the magnetic induction sensor cannot sense the magnetism of the magnetic block on the anti-dismantling block, thereby causing the processor to send out an alarm signal. This alarm signal can be directly transmitted in an audible and visual manner, or it can be sent to a monitoring platform or the captain's mobile phone.

[0034] Specifically, the mounting bracket 2 has an upper top piece 21 and L-shaped pieces 22 on both sides of the upper top piece. The L-shaped pieces 22 have a vertical part and a horizontal part. The L-shaped pieces 22 are arranged opposite to each other left and right. The upper end of the vertical part is integrally formed and connected to one side wall of the upper top piece. The lower end of the vertical part is perpendicular to the horizontal part. The two vertical parts are between the two horizontal parts. The upper top piece 21 is in contact with the bottom surface of the bottom shell 12 and is locked together by screws. Through holes 221 penetrating up and down are respectively formed on the front and rear sides of the horizontal part. The horizontal part is stacked on the protective sleeve 4 with an open top surface at the position of the through hole. A locking screw 5 passing through the protective sleeve 4 and outside the through hole 211 is arranged in the protective sleeve 4. A sealing cover 41 is embedded on the upper end port of the protective sleeve 4. The locking screw 5 is hidden inside by using this sealing cover 41, making it impossible for outsiders to disassemble the shell, achieving an anti-disassembly effect. The mounting bracket is also used to dissipate heat from the components inside the circuit board, enabling air convection at the bottom of the shell.

[0035] Furthermore, a through mounting hole 211 is formed on the upper top piece 21. The anti-disassembly block 3 is erected. The upper end of the anti-disassembly block 3 passes through the mounting hole 211 into the exposed window. The lower part of the anti-disassembly block 3 is below the upper top piece 21. An installation ring 31 protrudes outward from the lower end of the anti-disassembly block 3. Locking screws 6 are installed on the front and rear sides of the anti-disassembly block 3 outside the installation ring 31. The AIS card is hidden at the lower bottom surface of the shell by using the anti-disassembly block 3, which cannot be seen by anyone, further achieving an anti-disassembly effect and also having a waterproof effect.

[0036] In the present invention, an alarm switch can also be installed at the window of the bottom shell. The top of the anti-disassembly block 3 extends into the window and presses the alarm switch. The alarm switch is signal-transmission connected to the processor on the circuit board. During application, under normal use, the anti-disassembly block 3 presses the alarm switch. If the shell is separated from the anti-disassembly block 3, the alarm switch is released, and the processor receives the signal that the alarm switch is disconnected and processes an alarm signal for equipment disassembly. This alarm signal can be in the form of sound, light, or can also be sent to the monitoring center or the crew's mobile phones. The notification of the alarm signal can be diverse, which is a well-known technology and will not be elaborated here.

[0037] The above embodiments do not limit the form of the present invention. Any appropriate changes or modifications made by those of ordinary skill in the art shall be regarded as not departing from the patent scope of the present invention.
