Description

Technical Field

[0001] This application relates to the field of ship control technology, and in particular to a ship engine telegraph system and its control method. Background Technology

[0002] Modern ships have increasingly higher requirements for engine room automation and maneuvering safety. The ship's engine telegraph system, as a crucial device for transmitting information during navigation, is used to send main engine operation commands and relay operational information between operating parts. Based on ship automation procedures, the ship's engine telegraph system can be used as both a command telegraph and an emergency command telegraph, making it an indispensable piece of equipment for achieving ship engine room automation.

[0003] Currently, shipboard telegraph systems fall into two categories: one uses a synchro control circuit to display commands, and the other uses manual cams or push-button switches in conjunction with indicator lights. However, due to the complex structure of ships, cable installation through hulls is difficult, and the complex electromagnetic environment makes communication data susceptible to interference, easily leading to slow command response and high false alarm rates. Furthermore, individual telegraphs have poor scalability and lack data recording and storage capabilities; a loss of communication with the navigation data recorder results in the permanent loss of navigation data. Summary of the Invention

[0033] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] The terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that the embodiments described herein can be implemented in a sequence other than that illustrated or described herein.

[0035] To address the problem of communication data being easily interfered with and causing permanent loss of navigation data in existing ship telegraph systems, this application provides a ship telegraph system and its control method. By providing a controller that connects to a first telegraph system via a first network and to a second telegraph system via a second network, the problem of communication data being easily interfered with in ship telegraph systems can be solved since the first and second networks are independent and different networks. In addition, the controller can record the operating status and command information of the ship telegraph system, which can solve the problem of permanent loss of navigation data. Furthermore, the controller can switch operating modes under its control to ensure the safety of ship navigation.

[0036] The following is combined Figures 1-4 This application describes the ship's telegraph system and its control method.

[0037] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of the ship's telegraph system provided in this application. A ship's telegraph system includes a first telegraph system, a second telegraph system, and a controller.

[0038] For example, the controller is connected to the first engine telegraph system via a first network and to the second engine telegraph system via a second network, for recording the operating status and order information of the ship's engine telegraph system, and for controlling the operating mode of the ship's engine telegraph system, the operating mode including the first engine telegraph operating mode and the second engine telegraph operating mode.

[0039] When the ship's telegraph system is in the first telegraph operating mode, the controller sets the second telegraph system as a backup system that operates synchronously with the first telegraph system. It generates corresponding control information from the received operation commands and displays it through the first telegraph system. When the first telegraph operating mode fails, it switches to the second telegraph operating mode.

[0040] When the ship's telegraph system is in the second telegraph operation mode, the controller generates corresponding control information based on the received operation instructions and displays it through the second telegraph system. When a fault occurs in the second telegraph operation mode, a fault alarm command is issued.

[0041] The first car telegraph system mentioned above can be a master car telegraph system, the second car telegraph system can be an emergency car telegraph system, and the controller can be a programmable logic controller (PLC). The first network can be a redundant industrial Ethernet network, and the second network can be a redundant Modbus 485 communication network.

[0042] The ship telegraph system described in this application is illustrated by an embodiment below.

[0043] Please refer toFigure 2 , Figure 2 This is a schematic diagram of the structure of a ship's telegraph system provided in an embodiment of this application. A ship's telegraph system includes a first telegraph system, a second telegraph system, and a controller. The first telegraph system can be a main telegraph system, and the second telegraph system can be an emergency telegraph system.

[0044] For example, the first car telegraph system includes multiple first car telegraph dual-transmitters, multiple first car telegraph single-receivers, and multiple first car telegraph single-repeaters, and the first car telegraph dual-transmitters, the first car telegraph single-receivers, and the first car telegraph single-repeaters interact with each other through the first network.

[0045] The vehicle telegraph control system described in this application may include a first vehicle telegraph system with two channels. When one channel is an active control unit, the other channel is in hot standby mode, which can realize real-time data synchronization. When the channel that is in main control fails, the hot standby channel can also be promoted to main control.

[0046] For example, Figure 2 The two first car telegraph dual-machine transmitters shown are located on the left side of the first part and the right side of the second part, respectively. The first car telegraph dual-machine transmitter located on the left side of the first part is one channel, and the first car telegraph transmitter located on the right side of the second part is the other channel.

[0047] Specifically, Figure 2 The diagram shows four single-unit receivers for the first carriage bell, and one dual-unit transmitter for the first carriage bell corresponds to two single-unit receivers. Two of these single-unit receivers are located on the right side of the second section, and the other two are located in the third section. Similarly, these four single-unit receivers form two channels of the first carriage bell system, with each channel consisting of two single-unit receivers.

[0048] Specifically, Figure 2 Two single-unit repeaters for the first car telegraph are shown. These two single-unit repeaters for the first car telegraph are located in the fourth part and also form two channels of the first car telegraph system.

[0049] It should be noted that the first part mentioned above is part A of the driver's cab, the second part is part B of the electromechanical control room, the third part is part C of the electromechanical compartment, and the fourth part is part D of the electromechanical compartment.

[0050] For example, the first vehicle telegraph dual-machine transmitter is equipped with components such as a command issuing part button, a command receiving part button, a handle, a buzzer, and indicator lights. The command issuing or receiving part is selected by the button, and different vehicle command information is issued by changing the position of the handle. At the same time, the indicator lights and buzzer on its own control panel provide feedback on the current operating status and operating mode, and the operating status and vehicle command information are exchanged with the controller through the first network.

[0051] For example, the first vehicle telegraph receiver is equipped with a command location button, a buzzer, and indicator lights. The command location is selected by the button, and different vehicle command information is responded to by the button. At the same time, the indicator lights and buzzer on its own control panel provide feedback on the current operating status and operating mode.

[0052] For example, the first single-unit repeater of the car telegraph is used to display information about the issuing location, the receiving location, and the car's position. The first single-unit repeater of the car telegraph can be a 5-inch display screen, which communicates with the first dual-unit transmitter of the car telegraph via a first network to analyze the operating data of the main car telegraph in real time, and displays the issuing location, receiving location, and car's position information on its display screen.

[0053] For example, the second car telegraph system includes multiple second car telegraph dual-transmitters, multiple second car telegraph single-receivers, multiple second car telegraph dual-repeaters, and multiple electronic alarms, which are connected to each other via a second network.

[0054] The vehicle telegraph control system described in this application may include a second vehicle telegraph system with two channels, wherein when one channel is an active control unit, the other channel is in a hot standby state. For example, Figure 2 The two second car bell dual-machine transmitters shown are located on the left side of the first part and the right side of the second part, respectively. The second car bell dual-machine transmitter located on the left side of the first part is one channel, and the second car bell transmitter located on the right side of the second part is the other channel.

[0055] Specifically, Figure 2 The diagram shows four single-unit receivers for the second carriage bell, with one dual-unit transmitter corresponding to two single-unit receivers. Two of these single-unit receivers are located in the third section, and the other two are located in the fourth section. Similarly, these four single-unit receivers form two channels of the second carriage bell system, with each channel consisting of two receivers.

[0056] Specifically, Figure 3 Two second car telegraph repeaters are shown, located in the second and third parts respectively. These two second car telegraph repeaters correspond to the two second car telegraph transmitters located in the first part.

[0057] For example, the second vehicle telegraph dual-machine transmitter includes components such as a command issuing part button, a command receiving part button, a vehicle command position button, a buzzer, and indicator lights. The command issuing or receiving part is selected by the button, and different vehicle command information is sent by pressing the vehicle command position button. At the same time, the indicator lights and buzzer on its own control panel provide feedback on the current operating status and operating mode, and the operating status and vehicle command information are exchanged with the controller through the second network.

[0058] For example, the second vehicle telegraph receiver includes components such as a command receiving part button, a buzzer, and indicator lights. The command receiving part is selected by the button, and different vehicle command information is responded to by the button. At the same time, the indicator lights and buzzer on its own control panel provide feedback on the current operating status and operating mode. It also interacts with the controller through the second network to exchange data such as operating status and vehicle command information.

[0059] For example, the second vehicle telegraph dual-function repeater is used to display information about the issuing location, the receiving location, and the vehicle's position. The second vehicle telegraph dual-function repeater can be a 7-inch display screen, which communicates control data with the controller via a second network, analyzes the emergency vehicle telegraph's operating data in real time, and displays the issuing location, receiving location, and vehicle's position information on its display screen.

[0060] For example, the controller can interact with the first dual-unit transmitter, the first single-unit receiver, and the first single-unit repeater of the first telegraph system via a first network, and can also interact with the second dual-unit transmitter, the second single-unit receiver, and the second dual-unit repeater of the second telegraph system via a second network. The controller can also select and switch control modes according to different operating modes of the ship's telegraph system described in this application, and transmit information such as the issuing location, receiving location, and telegraph position to the second telegraph system. Simultaneously, it can transmit the operating status and telegraph information of the ship's telegraph system described in this application to a third-party ship information network via the second network.

[0061] Therefore, it can be seen that the first dual-machine transmitter of the ship's telegraph system can use the controller to analyze the operating status and command information of the ship's telegraph system. Furthermore, the first dual-machine transmitter of the ship's telegraph system, the first single-machine receiver of the ship's telegraph system, and the first single-machine repeater of the ship's telegraph system can also display the command issuing location, command receiving location, and command position information.

[0062] Similarly, the second dual-machine transmitter can use the controller to analyze the operating status and command information of the ship's telegraph system, and can also display the issuing location, receiving location and command position information through the second dual-machine transmitter, the second single-machine receiver, and the second dual-machine repeater.

[0063] In summary, this application provides a controller that connects to a first telegraph system via a first network and to a second telegraph system via a second network. Since the first and second networks are independent and different networks, the problem of communication data in ship telegraph systems being easily interfered with can be solved. In addition, the controller can record the operating status and command information of the ship telegraph system, which can solve the problem of permanent loss of navigation data. Furthermore, the controller can switch operating modes under its control, ensuring the safety of ship navigation.

[0068] Step 330: If the second car bell is in operation mode, the controller will generate corresponding control information from the received operation instructions and display it through the second car bell system.
