3 is a flowchart illustrating a method of operating a gateway device for an IP-based integrated in-ship communication system according to an embodiment of the present invention.

In step S101, the gateway device 120 initializes the communication port settings to RS-422 for the communication interface and 38,400 bps for the transmission rate when the gateway device is initially driven.

In step S102 , the gateway device 120 connects the data transmission cables of one or more broadcasting/communication devices to the communication port of one gateway device 120 .

In step S103, the gateway device 120 waits in the reception state to see if there is data transmitted from the broadcasting/communication device connected to the corresponding port for a predetermined time. Among the broadcasting/communication devices that require mandatory installation on ships, devices that allow short-distance remote operation through the remote function periodically transmit device cycle status information through RS-422 and RS-485 interfaces in compliance with the NMEA0183 or NMEA2000 protocol. do. The gateway device 120 receives periodic state information from a broadcasting/communication device. However, devices and systems that do not support the remote function, in particular, devices configured with AC voltage relays such as Ship Alarm, or communication systems operated exclusively for local use, do not transmit periodic status information. The gateway device 120 may periodically receive device status information through connection with a separate input/output (I/O) device for remote control at the rear end of the communication device.

In step S104, the gateway device 120 checks whether a signal component (voltage) in the 422 RX signal line is detected.

In step S105, if the signal component (voltage) in the 422 RX signal line is not detected, that is, if the signal component in the corresponding signal line is not detected, the gateway device 120 updates and switches the setting value to the 485 interface mode, and from step S103 again carry out

In step S106, when a signal component (voltage) in the 422 RX signal line is detected, the gateway device 120 checks whether data received in the reception buffer is detected.

In step S107, when the received data in the reception buffer is detected, the gateway device 120 analyzes the data packet. The gateway device 120 searches for a data transmission rate through steps S1071 and S1072, and searches for a device mode. The gateway device 120 discovers the data transmission rate of the device connected to the corresponding communication port and the type of the connected device through the transmission rate search unit and the device mode search unit shown in FIG. 3 . If the transmission speed of the currently received data packet is different from the transmission speed of the communication port set as the initial value, even if the data packet is broken, it is possible to know whether a garbage value has entered the UART communication buffer. The gateway device 120 may detect whether data is received. For a device that does not support the remote function, the gateway device 120 registers the device information in advance using a protocol having an address value in a frame format, such as a user-specified ID in the NMEA protocol or the Modbus protocol. The gateway device 120 is configured by linking a separate I/O device for remote control using the same, and can operate as a remote function. The gateway device 120 may search for a data sender through this.

In step S108, if the received data in the reception buffer is not detected, the gateway device 120 generates an alarm message for connection state abnormality.

In step S109, the gateway device 120 checks whether the device mode set as an initial value matches the discovered device mode.

In step S110 , when the initial setting mode and the currently discovered device mode match, the gateway device 120 links the IP network between the broadcasting/communication device and the main control server 130 .

In step S111, if the initial setting mode and the currently discovered device mode do not match, the gateway device 120 changes the device mode and generates a device mode change message.

In step S112 , the gateway device 120 transmits the generated device mode change message to the main control server 130 , and links the IP network between the corresponding broadcasting/communication device and the main control server 130 based on the changed device mode Step S110 is performed.

4 is a flowchart of a data transmission rate search method in a method of operating a gateway device according to an embodiment of the present invention.

FIG. 4 is a detailed flowchart of step S1071 shown in FIG. 3 . 4 is a schematic flow diagram of a method of searching for a transmission rate of a data packet received from an arbitrary connected device using a start character and a separator character in a received NMEA0183 data packet as a sequential flow.

In step S201, when the data in the UART reception buffer is detected, the gateway device 120 declares a variable for driving the baud rate search module and sets a setting value (eg, an initial value of 38,400 bps) of the baud rate.

In step S202, the gateway device 120 reads the received data string at a baud rate set as an initial value. Here, the gateway device 120 can detect whether or not data is received because it can know what value has entered the UART communication buffer, even if it is a garbage value, even if the data packet is broken because it is different from the data transmission speed of the communication port set as the initial value. .

In step S203 , the gateway device 120 checks whether the start character and the 7th delimiter in the character string of the received data packet match the preset start character value ('$') and the delimiter value (','). That is, the gateway device 120 is a baud rate between devices constituting communication set through whether the start character and the 7th separator character match the preset start character value ('$') and the separator character value (','). can be determined to match.

In step S204, the gateway device 120 switches if the starting character and the 7th separator in the string of the received data packet do not match the preset starting character value ('$') and the separator character value (',') Check the data transfer rate to be performed.

In step S205, when it is determined that the baud rates between the devices constituting the communication do not match each other, the gateway device 120 sequentially changes the baud rate setting values to repeatedly perform the discrimination operation. For example, the gateway device 120 sequentially changes the data transfer rate to be switched from the baud rate of Case 1 (eg, 9,600) to the baud rate of Case 5 (eg, 57,600). And, for each sequentially changed baud rate, the gateway device 120 performs again from step S201 and checks whether the start character and the delimiter match the preset start character value ('$') and the delimiter value (','). . The order of searching by changing the initial setting value of the gateway device 120 and the setting value in the loop may be prioritized based on the transmission speed mainly used by the marine devices. This can reduce the search time of the data transfer rate. The data transfer rate to be sequentially changed is not limited to a specific data transfer rate as in Cases 1 to 5. The gateway device 120 may search by additionally designating a case for other transmission rates (eg, 14,400, 28,800, etc.) not shown in FIG. 5 .

5 is a flowchart of a device mode discovery method in a method of operating a gateway device according to an embodiment of the present invention.

5 is a detailed flowchart of step S1072 shown in FIG. 5 is a diagram illustrating a method of searching for a device mode by analyzing a Talker ID in a received NMEA0183 data packet as a sequential flow.

In step S301, the gateway device 120 extracts the device registration list and the talker ID in the list.

In step S302, the gateway device 120 extracts only the talker ID of whether registration is 'Y' (device registration).

6 is a diagram illustrating an operation of extracting a device registration list and talker ID used in an embodiment of the present invention.

As shown in FIG. 6 , the gateway device 120 calls the device registration list 701 installed/equipped in the ship from the main control server 130 . The gateway device 120 receives the device registration list 701 and checks the registration status item 702 . That is, the gateway device 120 extracts discovery ID information from the device list 703 that is registered as a device in the device registration list 701 installed/equipped in the ship, but is not currently connected. . The talker ID of the NMEA0183 protocol defined in the IEC61162 standard is the same as in [Table 1] of FIG. If the scope of the search target is not narrowed in the above manner, unnecessary time and resources may be consumed to search all talker IDs. A device using a communication protocol other than the NMEA protocol (eg, Modbus, etc.) uses the same method. When it is determined in the transmission rate discovery module that the received data string is not the NMEA protocol, the gateway device 120 converts the conditional expression into a conditional expression according to the Modbus protocol data packet structure and performs the search process in the same manner. .

Meanwhile, in step S303 of FIG. 5 , the gateway device 120 sets an initial value of the talker ID for device mode discovery.

In step S304, the gateway device 120 reads the set talker ID initial value and the character string of the received data packet.

In step S305, the gateway device 120 determines whether the second and third characters of the received data string match the talker ID to be searched.

In step S306, if the second and third characters match the talker ID to be searched, the gateway device 120 returns a character string for the talker ID to be searched. That is, the gateway device 120 determines the device mode to be searched as the device mode matching the returned string, and ends the device mode search operation.

In step S307, if the second and third characters and the talker ID to be searched do not match, the gateway device 120 confirms a switching target of the talker ID to be searched.

In step S308, the gateway device 120 repeatedly performs the discrimination operation by sequentially changing the talker ID to be searched. For example, the gateway device 120 sets the switching target of the talker ID to be searched from the talker ID of case 1 (eg, Automatic identification system (AIS)) to case 2 (eg, Radio-Telephone (MF/HF)), case 3 (eg, radio-telephone (VHF)) and Case 4 (eg, Weather Instrument)) are sequentially changed. Then, for each sequentially changed talker ID, the gateway device 120 performs again from step S304 to check whether the second and third characters match the talker ID to be searched. The searched talker ID order may be prioritized based on the talker ID mainly used by marine devices. This can reduce the search time of the talker ID. The gateway device 120 may search by additionally designating a case for other talker IDs not shown in FIG. 5 .

7 is a diagram illustrating a table for talker IDs used in an embodiment of the present invention.

[Table 1] shown in FIG. 7 is a table of talker IDs of the NMEA0183 protocol defined in the IEC61162 standard.

The NMEA0183 protocol defines talker IDs for communication devices such as AIS, DSC, VHF, and MF/HF, and for major safety facilities in ships such as engine room monitoring systems and fire detection systems. For other undefined devices, it is possible to separately designate IDs by user definition. In addition, for devices that do not allow even a short-range remote function, the device information is registered in advance using a protocol having an address value in the frame format, such as the Modbus protocol, and a separate I/O device for remote control using it By configuring in conjunction with the data sender can be searched.
