Description

Technical Field

[0001] The utility model relates to the field of ship communication control, and in particular to a ship's remote identification interactive control system and a ship. Background Art

[0002] The safety of ship navigation is very important, because the navigation of a ship is different from that of a car, so it is necessary to obtain relevant information of other ships in order to adjust the driving according to the information of the surrounding ships, thereby ensuring the safety of the ship's driving. In order to realize the remote interactive identification control of ships, the prior art has developed an AI S system for realizing data interaction between ships, thereby improving the safety of ship driving and providing some driving data for ship drivers to operate ships; such as a mobile AI S receiver for inland ships with patent application number 201721448341.0, comprising a shell, a through hole is opened on one side of the shell, a first terminal is passed through the through hole, a second terminal is fixedly connected to one side of the first terminal, a third terminal is fixedly connected to one side of the second terminal away from the first terminal, a fourth terminal is fixedly connected to one side of the third terminal away from the second terminal, a fifth terminal is fixedly connected to one side of the fourth terminal away from the third terminal, a data line is plugged into the fifth terminal, a sixth terminal is plugged into one end of the data line away from the fifth terminal, and the sixth terminal is fixedly connected to one side of the signaler. The inland river vessel mobile AIS mobile receiver has the advantages of strong maneuverability, easy to carry, easy to operate, stable receiving signal and strong shock absorption effect.

[0003] Through the above-mentioned inland river ship mobile AI S mobile receiver, the signal of other ships can be received to facilitate the driver's driving reference data, thereby achieving the purpose of remote interactive identification and improving the safety of ship driving. However, the traditional AI S system also has certain defects, such as the hard-wired connection in the traditional AI S system, the interface used is not unified, and it is relatively confusing. Moreover, the AI ​​S system only supports passive safety, that is, the driver needs to judge the safety of the driving situation based on the AI ​​S data, and cannot automatically judge based on the AI ​​S information and actively issue an alarm reminder.

[0012] The following is a brief description of the contents expressed in the drawings of the present invention and the symbols in the drawings:

[0013] Figure 1 This is a schematic diagram of the control system principle of the utility model. DETAILED DESCRIPTION

[0014] The specific implementation of the present invention will be further explained in detail below by describing the optimal embodiment with reference to the accompanying drawings.

[0015] The full name of the AIS system is the Automatic Identification System for Ships. It exchanges information between ships through the network to achieve ship identification, so that the information of other ships besides the own ship can be displayed, which is convenient for the driver of the own ship to adjust and control the navigation according to the information, thereby improving driving safety. However, the interface of the AIS system in the prior art is complex, which is relatively confusing for management. The inconsistent interface poses problems for subsequent processing control, maintenance and replacement of components. Therefore, this embodiment designs an integrated remote identification interactive control system (AIS system) for ships with a unified communication interface, which integrates all control components together and obtains information through a unified communication interface with the outside world, which is convenient for subsequent maintenance, repair, replacement, etc. The specific scheme is as follows: Figure 1 As shown, it includes a main control board, on which a communication controller, a VHF transceiver, a duplexer, a positioning receiver, a ship motion sensor, a display driver module, and a first CAN interface, a second CAN interface, a third CAN interface, and a fourth CAN interface are arranged; the communication controller is connected to the first CAN interface through the display driver module, and the first CAN interface is connected to the display terminal; the communication controller is connected to the second CAN interface through the ship motion sensor, and the second CAN interface is used to connect the shipborne data device; the communication controller is connected to the duplexer through the VHF transceiver, and the duplexer is connected to the third CAN interface, and the third CAN interface is connected to the VHF antenna; the communication controller is connected to the positioning receiver, and the positioning receiver is connected to the fourth CAN interface, and the fourth CAN interface is used to connect to the Beidou / GPS antenna. The shipborne data equipment includes a compass, a speedometer, a rudder angle indicator, and a navigator. The first, second, third, and fourth CAN interfaces are all CAN interface modules of the same unified standard, which have a CAN interface and its corresponding drive and communication circuits, and can obtain external data through CAN communication to realize data interaction between the main control board and external devices.

[0016] Ship motion sensor: mainly processes ship motion data transmitted from external devices such as compass, speed meter, rudder angle, navigator and other devices. Display module: outputs display information; VHF transceiver: receives and sends VHF information, which can be used to identify this system and other system information. Duplexer: can process both sending information and receiving signals. Positioning receiver: processes positioning information transmitted from Beidou and GPS antennas. Communication controller: main processing unit, processing business logic.

[0017] In this embodiment, the navigation information of the ship, such as longitude and latitude, rudder angle, heading, navigation information and other ship information is connected to the main control board through the CAN interface. The ship motion sensor on the main control board converts the ship information, and the sampling conversion obtains the information required by the communication controller, including but not limited to AD sampling circuit, filter circuit, noise reduction circuit, etc., and then the communication controller sends it to the VHF antenna through the VHF transceiver and duplexer through the CAN interface, and the wireless information is sent out through the VHF antenna. The wireless signal is used to be received by other ships; the positioning signal received by the GPS or Beidou antenna is sent to the positioning receiver through the CAN interface, and the positioning receiver sends the positioning signal to the positioning receiver through the CAN interface. After the bit information is processed, it is sent to the communication controller, and then the communication controller sends it to the VHF antenna through the VHF transceiver and duplexer via the CAN interface, and the wireless information is sent out through the VHF antenna. The wireless signal is used to be received by other ships; similarly, this ship receives information from other ships through the VHF antenna, and then sends it to the duplexer through the CAN interface. After the duplexer processes it, it is forwarded to the communication controller through the VHF transceiver. The communication controller is connected to the CAN interface through the display module, and then the display terminal connected to the CAN interface displays the navigation information of nearby ships. The driver controls the navigation of this ship based on the information of nearby ships. The display module is a display driver circuit, which mainly outputs drive signals and video signals to the display terminal, so that the display terminal can display data.

[0018] In a preferred embodiment of the present application, the AIS system is further improved, and a distance calculation module, a fifth CAN interface, and an alarm are also provided on the main control board; the distance calculation module is connected to the communication controller, and the communication controller is connected to the fifth CAN interface, and the fifth CAN interface is used to connect the collision warning alarm. Since the received information of nearby ships has GPS positioning, and the ship also has GPS positioning, the distance calculation module can simply calculate the distance between the ship and the nearby ships by obtaining the positioning information of both through the communication controller. When the distance is less than the set threshold, the alarm connected through the CAN interface issues a collision warning, realizing an active distance warning, and timely reminding the driver to pay attention to navigation safety, which is particularly suitable for unclear vision such as fog and heavy rain. The active collision warning function can greatly improve the safety of ship navigation. The collision warning alarm includes a multi-color indicator light, and the communication controller drives and controls the lighting state and color of the multi-color indicator light through the fifth CAN interface. According to the distance between the ship and the nearby ships, different color warnings are controlled. If all ships are greater than the safety threshold, green is displayed, and if it is less than the safety distance threshold and greater than the collision threshold, the yellow indicator light is lit; if it is less than the collision distance threshold, a red indicator light is displayed and flashes to remind. The safety distance threshold and collision distance threshold here can be calibrated and set.

[0019] In a preferred embodiment of the present application, a fault detection module and a fault indicator light are also provided on the main control board. The fault detection module is used to detect whether the circuit between the third CAN interface and the communication controller is faulty, and its output end is connected to the communication controller, and the output end of the communication controller is connected to the fault indicator light, which is used to send a fault reminder signal. The core of the AIS system is that the communication circuit between the communication controller and the antenna is normal. If this circuit is abnormal, it will cause system failure and even give wrong indication information. For example, because the communication circuit is disconnected due to a fault, it is impossible to receive information about nearby ships and mistakenly think that there are no ships nearby, affecting the safety of ship navigation. Therefore, a fault detection module is provided to detect whether the communication between the communication controller and the outside world is disconnected. The fault here refers to disconnection, and it is impossible to receive external signals. Therefore, the fault detection module can use a voltage or current acquisition circuit to collect whether there is an electrical signal between the communication controller and the VHF transceiver or whether there is an electrical signal between the VHF transceiver and the duplexer or whether there is an electrical signal in the circuit between the duplexer and the CAN interface and judge whether it is in a disconnected state based on this. If the communication is disconnected, the communication controller drives the fault indicator light to send a fault reminder, which is convenient for timely maintenance and processing. The fault alarm indicator light can also send out an alarm reminder sound through the ship's horn and other alarms, thereby improving the communication reliability of the AIS system and timely discovering communication anomalies and repairing them.

[0020] This embodiment also provides a ship, which includes the remote identification interactive control system in the above embodiment. Since the ship includes the identification interactive control system in the above embodiment, it has all the characteristics and advantages of the interactive identification control system in the above embodiment.

[0021] Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, they are all within the protection scope of the present invention.
