Description

The utility model relates to the field of navigation and mobile communications and can be used in monitoring tasks of fishing and other sea and river vessels.

Legislation in force in Russia and a number of countries has established the mandatory equipment of fishing vessels with technical control equipment (TSC), which provides periodic transmission of the coordinates of the position, course and speed of the vessel to the fishery monitoring center. Monitoring of fishing vessels equipped with TSC is provided within the framework of the industry monitoring system (OSM) of the Russian Fisheries.

At present, INMARSAT-S satellite communication terminals with a built-in GPS receiver and / or transmitters of the satellite positioning system for moving objects (based on the Doppler effect) ARGOS are used as TSC.

The disadvantages of using these terminals are:

- distortion of the position data of the vessel by unscrupulous fisheries participants by connecting simulators instead of navigation equipment and providing false information about the location and maneuvers of the vessel to the navigation information system;

- lack of a perfect communication system "ship" - "shore";

- the high cost of the used communication and telematics services represented by INMARSAT and ARGOS systems;

- limited use of GLONASS navigation technologies;

- the lack of objective control over fishing operations.

Known ship monitoring system (CMC) "Victoria" (see Http // Victoria.marsat.ru), designed for automated monitoring and control of the location of sea and mixed (river-sea) navigation of ships. The system is based on the technical means of the INMARSAT-S and INMARSAT-D + marine mobile satellite communications, GLONASS / GPS global satellite navigation systems and using the Internet technologies.

CMC Victoria allows you to:

- automatically track the location of ships equipped with INMARSAT-S or INMARSAT-D + terminals in real time and provide this information with reference to electronic cards to remote users via WEB;

- exchange text messages to remote users with ships via INMARSAT-S channels or conditional messages with INMARSAT-D + terminals;

- send broadcast circular messages to ships;

- automatically receive signals from the ship security alert system (SSOO), identify the vessel, display the place of signal delivery on an electronic map, and automatically send SSOO messages with additional information to the ship at the assigned addresses (shipowners, coordination and rescue centers);

- maintain a complete database of ships (synchronized with the data of the Russian Maritime Register of Shipping and the Russian River Register), navigation restriction areas, coordination and rescue centers, and areas of responsibility of these centers (Violations of permitted navigation areas by vessels in accordance with their classes are automatically monitored) . Notifications of possible violations are automatically sent to supervisory authorities);

- track the history of the vessel for a specified period of time;

- provide temporary limited access to the system using guest passwords to track the movement of the vessel by consignors, consignees, charterers, and insurers.

A distinctive feature of CMC Victoria from the similar purpose Webtrack systems of BritishTelecom, PurpleFinder of PoleStar, TrackScape of TrackWell is the use of the vector map data format as opposed to the raster representation of maps in these systems.

The disadvantages of the system include the limited resource of data transmission channels and the inability to control the status of various ship systems and mechanisms.

By technical nature, the closest to the proposed technical solution is an integrated monitoring and control system for ships (see patent US 20090187297, publ. 07.23.2009.

In the system, data showing the current status of ship systems is transmitted from the ship to one or more remote locations, and commands are received from one or more remote locations to control the ship's systems.

The ship monitoring system is designed to monitor various ship operating systems and provide communication with remote locations using various means of communication. A ship monitoring system includes a processor and various sensors for monitoring a variety of ship operating systems. Communication facilities selectively communicate with remote locations. A communication medium selected from a plurality uses a communication technique compatible with the communication technology of remote locations.

The invention also includes a method for monitoring ship operating systems, which consists in producing status signals for ship operating systems and selecting a remote location for receiving signals. It also defines a transmitting device for transmitting signals to a remote location compatible with the receiving device of the remote location.

The disadvantages of the invention should include the following:

- the receiver of the global navigation satellite system (GPS) is not allocated in the system as the main component of the monitoring system. The receiver may be included in the navigation subsystem, however, the methodology for using satellite navigation and its practical implementation are not given;

- the possibility of fragmented reading of the contents of the “black box” (Black Box) is not provided, in which the collected data from various sensors and the navigation subsystem are stored, from the monitoring points via satellite channels. This limits the effectiveness of the current monitoring of vessels, which is especially important in monitoring fishing vessels.

The proposed navigation and information system is designed for placement in a specialized center (centers) for monitoring an automated workstation (computer, server) with installed special software. This system involves equipping ships with specialized navigation and communications systems.

Monitoring of vessels can be carried out, depending on the nature of the use of the system, by fisheries monitoring centers, or other structures that provide monitoring and control of the movement of vessels, monitoring the status of various ship systems and equipment, etc.

When used in tasks of monitoring aquatic biological resources, monitoring and monitoring the activities of fishing vessels, this utility model provides advanced functions for collecting, processing, and storing data related to fishing, including data on vessel movement parameters.

The technical result of the claimed solution is the creation of a monitoring system for fishing and other marine and river vessels, providing through on-board navigation-connected systems the collection of information on navigation parameters (location, speed, course coordinates) of the vessel, information from the interfaced equipment (status sensors of various ship systems and mechanisms ), video cameras, etc., as well as the accumulation of this information in non-volatile memory (“black box”) and its transmission to the monitoring center via channels satellite and / or terrestrial communications.

The technical result is achieved by the fact that the system contains a monitoring center, including an automated workstation based on a personal computer with a processor, mobile satellite and / or terrestrial communications networks, the Internet, on-board navigation and communications systems, while an automated workstation based on a personal computer with the processor is connected to the on-board navigation-connected systems via mobile satellite and / or terrestrial communication networks and the Internet, with each on-board navigation-connected The first complex has an identification number and is configured to determine navigation parameters: location coordinates, speed, course, automatically detect faults, collect information from sensors, transmit navigation parameters along with the identification number to the monitoring center.

The on-board navigation-connected complex contains a GLONASS / GPS-containing navigation power supply unit interconnected via an interface, a navigation power receiver with an antenna connected to a controller to which a non-volatile storage device is connected, a linear interface driver; and a navigation and communications unit comprising a power device, transceivers of satellite or terrestrial communication systems connected to a microcomputer, to which a linear interface driver, non-volatile memory device, and linear drivers for interfacing with external devices are connected: a computer, a video camera, controllers of external sensors, display controller via standard Ethernet, USB, RS-232, RS-422, RS-485 interfaces.

The navigation receiver unit further comprises a built-in GSM / GPRS cellular communication modem with an antenna, which allows the exchange of information with the monitoring center via cellular communication channels, and / or an interface for connecting an additional transceiver of a satellite or terrestrial communication system.

At the same time, the on-board navigation-connected complex is capable of determining navigation parameters, collecting information from sensors connected via standard interfaces, detecting emergency situations, registering navigation parameters in non-volatile memory, and transmitting them to the monitoring center upon request.

The features and essence of the claimed utility model are illustrated by the following detailed description illustrated by the drawings, which shows the following:

The system contains a monitoring center 1, including an automated workstation (computer, server) 2, on which special software is installed, and monitoring center 1 is interconnected for data exchange via mobile satellite or terrestrial communication networks 3 ₁ ... 3 _N , or via the Internet 4 , with airborne navigation and communications systems 5 ₁ ... 5 _K.

For marine vessels, the most used mobile communication systems are the INMARSAT satellite communication systems (C, M, Fleet, BGAN standards), IRIDIUM, GLOBALSTAR, ORBKOM and others. A promising Russian satellite communication system providing 100 percent coverage of the globe is the Gonets- D1M ".

For river vessels, one of the main mobile communication systems can be a GSM cellular communication system.

The Internet can be used with the appropriate data transmission services from the telecom operator (for example, GSM mobile operators provide Internet access through the GPRS packet data service).

Each on-board navigation-connected complex 5 ₁ ... 5 _K contains a navigation receiver 6 unit interconnected via interface 8, designed to calculate navigation parameters using signals from global satellite navigation systems (GLONASS, GPS, etc.), and a navigation-connected unit 7, designed to collect information from various sensors and transmit navigation parameters and other information to the monitoring center 1.

Interface 8 provides asynchronous serial data transfer (UART) and implements standard serial interfaces RS-232, RS-422, RS-485.

Power supply from the ship network is supplied to the navigation receiver unit 6 and the navigation-connected unit 7 via the power supply circuit 9.

Physically, the connection between the unit of the navigation receiver 6 and the navigation-connected unit 7 is carried out through a special interconnect cable that provides switching of the interface 8 and power 9 lines.

The main control element of the unit of the navigation receiver 6, determining the algorithms of its operation, is the controller 11.

The controller can be executed, for example, on the STM32F103VET6 chip (STMicroelectronics company), which is a microcontroller based on the CORTEXM3 processor core (development of the ARM7 core).

The controller 11 is interconnected with non-volatile memory 15, intended for recording and storing data obtained as a result of the performance of the navigation functions by the unit of the navigation receiver. At a minimum, automatically detected power outages are recorded in the storage device. The storage device 15 can also accommodate the firmware of the navigation receiver unit if the internal memory of the controller 11 is not used for these purposes.

The storage device 15 can be implemented, for example, on one or more memory chips of one or different types (Flash, FRAM, etc.) types, for example, AT45DB161D (memory type - Flash), FM25L256B (memory type - FRAM).

The navigation receiver unit 6 also comprises a navigation receiver 12 with an antenna 13 connected to the controller 11.

The navigation receiver 12 provides the calculation of the navigation parameters of the vessel (coordinates of location, speed, course) and the determination of the current time from the signals of global navigation satellite systems (GLONASS, GPS, Galileo).

The navigation receiver 12 can be implemented, for example, on a module of a dual-system GLONASS / GPS receiver.

Data received from the receiver 12 and containing the calculated navigation parameters and time is processed by the controller 11, converted into the required format and transmitted to the navigation-connected unit 7 via interface 8 with a set frequency, or upon request from the navigation-connected unit.

Line driver 14 provides level matching of the interface circuit of controller 11 with signals of interface 8.

Line driver 14 can be implemented, for example, on a MAX3160EAP microcircuit (Maxim), which provides hardware tuning for pairing with one of the RS-232 / RS-422 / RS-485 interfaces.

The line driver 14 may also support an interface 18 for connecting an additional transceiver of a satellite or terrestrial communication system. The expansion is provided when configuring the MAX3160EAP microcircuit RS-485 interface mode, for which several external paired devices can be connected in parallel.

The presence of the interface 18 allows you to use the unit of the navigation receiver 6 as a shortened version of the navigation-connected complex, providing a minimum of monitoring functions: determining navigation parameters and information interaction with the monitoring center. When this navigation-connected unit 7 may be absent.

The power device 10 provides the operation of the navigation receiver unit from the ship's power supply network.

The power device 10 contains a built-in power-off detector and is designed so that at the initial moment of voltage failure in the ship's power supply, the detector generates a corresponding signal to the controller 11. The power device provides, due to the accumulation of energy in the output filtering capacitors, the short-term operability of the navigation receiver unit, sufficient to record the fact and time of power off to the non-volatile memory 15. When the unit is turned back on, the power failure message stored in memory is transmitted via interface 8 to the navigation -connected unit, after which this message can be saved in the “black box” and transmitted to the monitoring center 1.

The power supply device 10 can be performed, for example, on several microcircuits (stabilizers and a power off detector): LM2593HVS (National Sem.), TPS7333QD (Texas Instruments), LMS33460MG (National Sem.).

The unit of the navigation receiver 6 may further comprise an integrated cellular communication modem 16 (GSM / GPRS, CDMA, etc.) with an antenna 17, which allows the exchange of information with the monitoring center 1 via cellular communication channels. The ability to organize data exchange via cellular communication channels is relevant, first of all, when monitoring river vessels, because in the waters of rivers this type of communication is often accessible and attractive because of the cheap schedule (in comparison with satellite communication systems).

Each navigation-connected unit 7 is built on the basis of a specialized built-in microcomputer 20 that provides all the functions of the named unit and the technical control means (TSC) as a whole.

Microcomputer 20:

- receives from the unit of the navigation receiver 6 current navigation data and time, as well as messages about the facts of power failure;

- manages the processes of automatic detection of equipment malfunctions and other emergency situations;

- controls the processes of writing to the storage device 22 ("black box") and the processes of reading information from the "black box";

- provides information pairing with a ship computer, including an electronic fishing journal (EPJ);

- controls the operation of transceivers of satellite and cellular communications;

- manages the processes of information exchange with the monitoring center 1.

The microcomputer 20 can be performed, for example, on an AT91SAM9G20B chip (Atmel), which is a microcontroller based on a high-performance ARM9 processor core with developed peripherals.

To the microcomputer 20 connected transceivers 24 ₁ ... 24 _M satellite or terrestrial communication systems. To connect transceivers in the microcontroller, RS-232, RS-422, RS-485, Ethernet interfaces are provided.

Through these interfaces, for example, the following models of satellite transceivers (terminals) of satellite communications can be connected to the microcomputer:

- JUE41 OF terminal (JRC Marine Electronics) INMARSAT Fleet standard, RS-232, Ethernet interfaces;

- SAILOR 500 terminal (Thrane & Thrane) Fleet Broad band standard, Ethernet interface.

To coordinate signal levels during information pairing with the unit of the navigation receiver 6 via interface 8, a linear driver 21 is used, connected to the microcomputer 20.

Line driver 21 can be implemented, for example, on a MAX3160EAP microcircuit (Maxim), which provides hardware tuning for pairing with one of the RS-232 / RS-422 / RS-485 interfaces (by analogy with the navigation receiver unit 6).

A non-volatile memory device 22 (“black box”) is connected to the microcomputer, which provides recording, storage and subsequent reading of navigation parameters and other information related to the monitoring functions.

The storage device can be performed, for example, on a flash memory chip K9F2G08U0A (Samsung).

The microcomputer also provides interfacing with external devices, such as a ship's computer (or electronic fishing log), a video camera, sensors (sensor controllers), a display panel, etc., through linear drivers 23 ₁ ... 23 _{L of} standard interfaces: Ethernet, USB, RS- 232, RS-422, RS-485.

Line drivers 23 ₁ ... 23 _L can be performed, for example, on microcircuits:

- MAX3232ESE (Maxim company) - RS-232 interface driver;

- MAX3485ESA (Maxim company) - RS-485 interface driver;

- MAX3160EAP (Maxim company) - a universal customizable driver for RS-232 / RS-422 / RS-485 interfaces;

- DM9161AEP (DAVICOM Sem.) - Ethernet interface driver.
