Description

The utility model relates to the field of ship automation, in particular to systems of control and management of technical means, designed to provide communication between the command and executive posts of marine vessels in order to provide control and monitoring of the main engines and propellers with adjustable pitch.

The well-known JET machine telegraph is manufactured by Neptune-Electro LLC, which serves to transmit control commands from one or two main engines from the wheelhouse to the engine room and receive answers about the execution of these commands (http://sudoelektrik.com/production/jet. php).

"JET" is a backup communication tool for remote automated control systems for the main engines installed on the ship. The engine telegraph "JET" consists of two main blocks - command and executive. The command unit is installed in the wheelhouse, and the executive in the engine room. The telegraph can transmit 10 basic commands for controlling the main engine of a ship, boat or yacht. As a communication line between the command and executive units of the machine telegraph, a digital current loop type communication line is used, and two wires of a standard pair-twisted ship cable are used to transmit information.

Also known is a system of machine telegraphs and tachometers of propeller shafts manufactured by JSC Marine Navigation Systems, designed to provide communication between the command and executive posts of marine vessels for the purpose of controlling and controlling the main engines (http://www.mns.spb.ru/pdf/ AC_MTT.pdf).

The system of engine telegraphs and propeller shaft tachometers contains the main and emergency engine telegraph devices, as well as propeller shaft tachometer devices installed in the command and executive posts of the ship system, connected via the voltage converter to the ship power system and interconnected by independent communication lines in the form of redundant CAN buses containing the main and backup channels, with the possibility of transmitting data between devices of the command and executive posts simultaneously on both analam. Additionally, the system includes control posts connected to command and executive posts via communication lines, containing transponder devices for the main and emergency telegraphs, as well as tachometer meters for propeller shafts.

The disadvantages of the above control systems include the need to use independent subsystems that are not connected to each other as part of the system, which requires an extensive communication network with a large number of cable connections, data duplication, increased power consumption, and ultimately leads to a decrease in the information content of the system as a whole.

A system of engine telegraphs and tachometers of propeller shafts is known, comprising a machine telegraph consisting of a driver and a transponder connected through a voltage converter to a ship power system and connected to each other via communication channels installed in the command and executive posts of the ship system, while the machine the telegraph contains instruments of the main and emergency machine telegraphs, and the system additionally contains tachometer instruments of the propeller shafts of the command and executive post blocks s connected by independent communication lines in the form of a redundant CAN bus containing the main and backup channels, with the possibility of transmitting data between the devices of the command and executive posts simultaneously on both channels (RF patent No. 131695, IPC B63H 21/21, B63H 21/22, 2013 publication).

Known technical solution can perform the functions of the main and emergency engine telegraph for only one operating mode of the propulsion system, and also can not work in the mode of setting the assigned speed of the vessel.

The technical problem solved by the claimed utility model is to increase the information content, reliability and ease of use on ships of communication systems between the command and executive posts of marine vessels to provide control and monitoring of engines and propellers with adjustable pitch, as well as providing the possibility of choosing the mode of operation of the ship’s system when movement in a group of ships.

The essence of the utility model is illustrated by drawings, representing embodiments of a device for assigning assigned moves (hereinafter UZNH).

In FIG. 1 shows a structural diagram of an emergency engine telegraph (hereinafter AMT) with ultrasonic testing; in FIG. 2 is a structural diagram of a main machine telegraph (hereinafter MT) with ultrasonic testing; in FIG. 3 is a structural diagram of AMT; in FIG. 4 is a structural diagram of a system of ultrasonic testing, consisting of two independent from each other parts of the equipment; in FIG. 5 - the front part of the panel UZNH-2-K; in FIG. 6 - the front parts of the panels UZNH-2-AMT left and right sides (hereinafter LB and PrB); in FIG. 7 - block UZNH-2-P, in FIG. 8 - the front part of the panel unit UZNH-2-P.

Structurally, the UZNH consists of three panels that are built into the console sections of the integrated bridge system, and two blocks mounted on a bulkhead in the engine rooms of the port and starboard.

As follows from FIG. 1 of the structural diagram, the device for assigning assigned moves (UZNH) consists of panels 1, 2 of the emergency engine telegraph, starboard and starboard (UZNH-2-AMT PrB, UZNH-2-AMT LB) and panel 3 of the assignment of assigned moves (UZNX-2 -K) installed in the wheelhouse 4, and display units 5 and 6 (UZNH-2-P), located respectively in the engine rooms 7, 8 of the left and right side.

UZNH-2-AMT Prb, UZNH-2-AMT LB panels are intended for assigning control commands to local control posts located in the engine rooms of the port and starboard.

The UZNH-2-K panel is designed to set the speed of the assigned stroke, select the operating modes of the propulsion system and the operating mode of the UZNH system. The UZNH system can operate in the emergency engine telegraph mode and the device for setting the assigned moves.

The UZNH-2-P block is designed to indicate given commands from the wheelhouse and to signal to the command post about the execution of given commands.

The panels are made of aluminum alloy and have a film design.

In FIG. Figure 2 shows a variant of the structural diagram when instead of the emergency machine telegraph, the main machine telegraph is used, and the assigned moves program (UZNH) consists of panels 9, 10 of the machine telegraph of the starboard and port side, respectively (UZNH-2-MT PrB, UZNX-2- MT LB) and panels 3 for assigning assigned moves (UZNH-2-K) installed in the wheelhouse 4 and indication units 5 and 6 (UZNH-2-P) located respectively in the engine rooms 7, 8 of the left and right side.

In FIG. 3 is a structural diagram of an emergency engine telegraph. For the emergency engine telegraph, panels 1 and 2 (UZNH-2-AMT) are used.

The structural diagram of the main engine telegraph is similar to the structure of the emergency engine telegraph. For the main machine telegraph, UZNX-2-MT panels (not shown) are used.

Figure 4 presents the structural diagram of the USNX, consisting of two independent from each other parts of the equipment. The first part of the equipment includes panels 9, 10 of the main engine telegraph, starboard and port, respectively (UZNH-2-MT PrB, UZNH-2-MT LB), panel 3 of the assigned moves (UZNX-2-K) and blocks indications 5, 6 (UZNH-2-P). The second part of the equipment includes panels 1, 2 of the emergency engine telegraph, respectively, of the starboard and port side (UZNH-2-AMT PrB, UZNH-2-AMT LB) connected to their display units 5 and 6 (UZNX-2-P )

Panel 3 (UZNH-2-K) provides buttons for selecting the operating mode of the propulsive installation (Fig. 5), which are used to select the table of the dependence of the engine speed and the rotation of the variable pitch propeller blades on the machine telegraph. The currently selected operating mode of the propulsion system is indicated by a highlighted indicator.

The following four operating modes of the propulsion system are provided:

COMB - operation of the propulsive complex in the "Combinatorial characteristic" mode;

POST STEP - operation of the propulsive complex in constant step mode;

POST OBOR - operation of the propulsive complex in constant speed mode;

EKNM - the operation of the propulsive complex in an economical mode.

Each operating mode of the propulsive installation is determined by its tables of the dependence of the engine speed and the rotation of the propeller blades of adjustable pitch on the position of the handle of the machine telegraph.

Downloading tables is carried out using special software that can be installed in an integrated bridge system, or on a personal computer (laptop). The operation of loading work tables into the memory of the controllers located in the UZNX-2-K, UZNX-2-AMT and UZNX-2-MT panels can be performed directly by the ship’s crew, which helps to keep this data confidential.

To control the execution of commands by executive posts, the command panels provide an indication of the operation of each executive post. After sending a command from the command panels, the indicators of the executive posts on the command panels begin to flash until a confirmation of the command has been received from the executive post, after which the indicator of the corresponding executive post turns into a steady light.

To accommodate UZNH, from two to four executive posts are provided, which can be located in the engine rooms of the starboard and port side, rooms of hydraulic units and others.

For the operation of each executive post, a UZNX-2-P block is provided (Fig. 7), including a panel 11, buttons 12, a light column 13, a sound column 14.

On the indicators of the assigned and set speed of the ship (Fig. 5) displays the values of the assigned and set course of the ship.

The value of the set speed is determined by the position of the handle of the machine telegraph.

To enter (in increments of 1 node) the values of the assigned stroke, use the buttons in the form of up and down arrows. Confirmation of the setpoint occurs using the “ENTER” button.

The device can operate in one of two operating modes: in the device mode of setting the assigned travel speed (USNH) and in the operation mode of the telegraph (AMT or MT). To indicate one of two operating modes and select it (UZNH and AMT), the corresponding indicators and buttons of operating modes are provided on the UZNX-2-K panel. On the UZNX-2-AMT (MT) panel, only indicators of operating modes are provided.

UZNH can work as a device for setting the assigned speed of the vessel when the UZNX-2-K panel is connected to a duplicated CAN network of the main or emergency engine telegraph.

To select the “UZNH” operating mode, it is necessary to press the “UZNH” button on the UZNH-2-K panel, after switching the panel to this operating mode, the “UZNX” indicator will light. To select the “AMT” or “MT” operating mode, it is necessary to press the “AMT” button on the UZNX-2-K panel, after switching the panel to this operating mode, the “AMT” or “MT” indicator will light.

When operating in the USNX mode in the conditions of excitement, when the machine telegraph command table may differ from the approved table, it is possible to correct copies of the main approved table by means of IMS and storing them in the memory of the USNX-2-K, taking into account corrections for strong and weak waves. The machine telegraph command table, taking into account the corrections for excitement, is called up using the “SILN” and “SLAB” buttons. Return to the main approved table by pressing the button for selecting the machine telegraph tables taking into account the correction for excitement.

In the event of a malfunction in the operation of blocks, panels, communication lines (APS signal), the UNEASR indicator flashes on command panels. APS signal is confirmed by a single press of the “QUIT / TEST” button, after which the malfunction indicator turns into a constant light. In the absence or disappearance of APS signals, the indicator light disappears.

On the panels UZNH-2-AMT and UZNX-2-MT are the buttons of the machine telegraph (Fig. 6). Each button corresponds to a specific position of the handle of the machine telegraph. In this case, up to 13 commands for controlling the main engines are used:

SPHV - the most complete move forward

PVC - full speed ahead

SHV - average progress

MHV - a small move forward

SMHV - the smallest move forward

IT'S B - get ahead

STOP - stop

TOVS N - get ready back

SMHN - the smallest move back

MHN - a small move back

SHN - average move back

PCN - full swing back

SPHN - the most complete move back.

When the main or emergency engine telegraph operates without the UZNH-2-K panel, only one table is used for the dependence of the engine speed and the angle of rotation of the blades of adjustable pitch screws on the position of the machine telegraph, corresponding to the combinatorial mode of operation of the propulsion system. This table is stored in the memory of the UZNK-2-AMT (MT) panels.

The UZNH system provides for a duplicated power supply network 1 5 DC 24 V and a communication network 16 using the CAN interface (Fig. 1 - Fig. 4).

On each panel and unit there is a 24 V main and backup power supply. The indicators indicating the presence of the main and backup power supply are “BASIC” and “RESERVE”. Also on the UZNH-2-K, UZNH-2-AMT and UZNH-2-MT panels, buttons for adjusting the brightness are provided, which are designed to change the brightness level of the indicators located on the front parts of the panels.

The direction of rotation of the blades to the reverse on the UZNX-2-K panel is indicated by a minus sign, and on the UZNX-2-P blocks an arrow with the inscription "BACK" is indicated.

On the block UZNH-2-P buttons are provided:

- to test the health of indicators located on

block;

- to mute the sound during the execution of one given command from the command post;

- to confirm the execution of the command.

Thus, the proposed technical solution allows the following functions:

- work in the mode of setting the assigned speed of the vessel in the mode of operation of the propulsive installation "combinatorial characteristic";

- work in the mode of the main or emergency engine telegraph for four modes of operation of the propulsive installation;

- the ability to select machine telegraph command tables with allowance for disturbance corrections;

- control and indication of the presence of power and breakage of communication lines;

- transfer of control between command posts;

- indication of the execution of given commands from local posts on command panels;

- display at the executive posts of the given engine speeds and the angle of rotation of the blades of adjustable pitch propellers.

The proposed device is auxiliary and can operate in the machine telegraph mode, the emergency machine telegraph and in the device mode of setting the speed of the assigned course. In all operating modes of the device, commands are sent from command panels to executive posts. For the operation of the device, one to two command-and-control posts are provided, which are located in the wheelhouse and at the central control station, and two or more executive posts (in engine rooms, rooms of hydraulic units, etc.). The number of executive units in the UZNH is determined by the number of local control posts for the main engines and adjustable pitch screws (from two to four).

The main advantages of the proposed technical solution is:

- the device for setting the assigned moves includes, in addition to the main and emergency engine telegraphs, the device for setting the assigned speed of the vessel, allowing movement in a group of vessels at one given speed;

- the operation of machine telegraphs can be carried out for several modes of operation of a propulsive installation: “combinatorial characteristic”, constant step, constant speed, economical stroke;
