- automatic processing and automatic transmission of processed data via a high-frequency communication channel to the vessel traffic control center.

Automatic data transfer is carried out using one of the following data transfer modes:

1 - zonal, when entering the port's area of responsibility;

2 - by time, regardless of the location of the vessel relative to

port;

The hardware and software data transmission platform provides automatic monitoring of the vessel's condition, mechanisms, crew, navigational conditions in the area of its navigation, and the availability of supplies.

Control is organized as follows:

1. The on-board subsystem of Fig. 1 automatically carries out, through the data collection unit 9, the centralized collection of data from the following sources:

- radar for the presence of objects near the vessel;

- navigation systems 11 on the location of the vessel;

- 12 ship monitoring sensors for its condition;

- sensors for monitoring mechanisms 13;

- electronic ship's log 14 on the state of reserves;

- electronic ship log or from human condition monitoring sensors 15 on the crew’s condition;

- from any other objects of control 16.

Data from the data collection unit 9 is sent to the control, collection, processing, display and transmission unit 1 to the control, collection, processing and transmission center 2, which also receives information about the navigation situation and control commands received automatically via a radio channel by the channel-forming means unit 6. At the same time, the control, collection, processing and transmission center 2 receives the coordinates of the vessel’s location from the GLONASS receiver 5, data on the presence of vessels in the navigation area, their movement parameters and calculated divergence parameters from the display device 3.

Data on the presence of vessels in the navigation area is received by display device 3 from automatic identification system 4 and from the control, collection, processing and transmission center 2. In display device 3, data on the presence of vessels in the navigation area is analyzed in automatic mode.

Based on the received data, display device 3 automatically calculates the parameters of vessel movement and recommended divergence courses with them, displays them on the navigation map and transmits the data to the control, collection, processing and transmission center 2.

Data Collection, Processing, and Transmission Center 2 automatically analyzes and processes all incoming data, generating an event log with a storage period of at least six calendar months. Simultaneously, data collection, processing, and transmission center 2 generates radio data from the event log, which is transmitted automatically via channel-forming unit 6 to the shore subsystem (Fig. 2) using one of four communication modes:

1 - zonal, when entering the port's area of responsibility;

2 - by time, regardless of the location of the vessel relative to

port;

3 - upon request from the vessel traffic control center;

4 - emergency, in case of an emergency.

Also, the control, collection, processing and transmission center 2 automatically generates data for transmission to the display device 3 for the purpose of visualizing the collected information.

2. The shore subsystem of Fig. 2, through the channel-forming means block 4, automatically receives data from the on-board subsystem of Fig. 1 and, through the transmitting and receiving module of the MF/HF frequency range 6, transmits the received data to the control, processing, display and data transmission block 1 to the control, processing and data transmission center 2.

At the same time, the control, processing and data transmission center 2 receives data from the display device 3 on the presence of vessels in the port’s area of responsibility, the calculated parameters of vessel movement and the recommended divergence courses.

Data on the presence of vessels in the navigation area is received by display device 3 from automatic identification system 11 and from the control, collection, processing and transmission center 2. In display device 3, the received data is analyzed automatically.

Based on the received data, display device 3 automatically calculates the parameters of vessel movement and recommended divergence courses, displays them on the navigation map and transmits the data to the control, collection, processing and transmission center 2.

Data Collection, Processing, and Transmission Center 2 automatically analyzes and processes all incoming data, generating an event log with a storage period of at least six calendar months. Simultaneously, Data Collection, Processing, and Transmission Center 2 generates a data file from the event log, which automatically transmits the file to Situation Center 8 via Ground Communications Channel Unit 7 over the unified information network.

Also, the control, collection, processing and transmission center 2 automatically generates data for transmission to the display device 3 for the purpose of visualizing the collected information.

The data file received by the situation center 8 is sent to the control and information processing center, where the received data is automatically analyzed and transmitted to the display device 9.

Display device 9 displays information received from vessels about their status, including the status of the crew, the serviceability of mechanisms, the presence of cargo and supplies, as well as the navigation situation in the port’s area of responsibility.

Situation Centre 8 analyses the received information and, if necessary, generates recommendations for vessel maneuvering and changes to their routes.

This information is automatically transmitted to the on-board subsystem in the reverse order to that given above.
