Description

Technical Field

[0001] The present invention relates to the technical field of ships, and in particular to a USB interface for transmitting data at a PMI (Personal Information Management) of a centralized control console. Background Art

[0002] During the commissioning or operation of a ship's main engine, it's often necessary to check its operating parameters to determine whether it's operating properly and whether there are any faults. This requires the main engine system to frequently communicate with the manufacturer's commissioning computer or copy data for analysis. However, traditional shipboard control consoles often lack dedicated USB ports for main engine data transmission. To perform data transmission, it's often necessary to open the back panel of the control console's main engine computer and connect it using a long data cable. This method is not only inconvenient, but also results in unstable connections due to the loose cable, which can easily affect the quality and efficiency of data transmission. Summary of the Invention

[0003] The purpose of the present invention is to provide a USB interface for transmitting data at a centralized control console PMI, so as to solve the problems raised in the above background technology.

[0004] To achieve the above objectives, the present invention provides the following technical solutions: a USB interface for transmitting data at the PMI of a centralized control console, comprising an embedded USB socket and a signal cable. The embedded USB socket and signal cable serve as interfaces for data transmission and are arranged on the table where the host computer of the centralized control console is located. The USB interface is suitable for the operation or debugging process of the ship's main engine. When the relevant operating parameters of the host are unreasonable, they can be directly changed through the USB interface. Specifically, the following steps are included:

[0005] S1. Connect external USB devices: directly plug the external USB device (such as debugging computer, U disk, etc.) into the embedded USB socket and signal cable on the central control console;

[0006] S2. Data transmission and viewing: Open the corresponding data viewing or transmission software on the external USB device and select data transmission with the host computer;

[0007] S3. Parameter analysis and adjustment: Check the host operating parameters on the debugging computer, such as speed, temperature, pressure, etc., and analyze whether the parameters are reasonable;

[0008] S4. Parameter modification and saving: If it is found that the host-related operating parameters are unreasonable, such as inaccurate settings of critical speed and clock speed, modify the parameters directly on the debugging computer through the USB interface;

[0009] S5. Data copy and backup: After the host debugging is completed, the host operation data is copied to a USB flash drive or other storage device through the USB interface for subsequent use or backup on the same series of ships;

[0010] S6. Disconnect and organize: After completing all operations and ensuring that data transfer is complete and there are no ongoing transfer tasks, safely unplug external USB devices and organize all devices and cables to avoid damaging the interface or devices.

[0011] Furthermore, in step S3, a special analysis software is run on the debugging computer, which can display and record the host operating parameters in real time and provide a parameter adjustment function.

[0012] Furthermore, the host operating parameters specifically include:

[0013] Speed: The rotational speed of the host, measured in revolutions per minute (rpm), used to measure the host's output power and performance;

[0014] Power: The mechanical power output of the main engine, measured in kilowatts (kW) or horsepower (hp), reflecting the workload and efficiency of the main engine;

[0015] Fuel consumption rate: The fuel consumption of the main engine at unit power, measured in grams per kilowatt-hour (g / kWh), used to measure the economy of the main engine;

[0016] Exhaust temperature: The temperature of the main engine exhaust system, in degrees Celsius (℃). Excessively high exhaust temperature indicates incomplete combustion or a problem with the cooling system.

[0017] Lubricating oil pressure: The pressure of the main engine lubrication system, measured in bar or megapascals (MPa). Insufficient lubricating oil pressure can lead to poor lubrication and mechanical wear.

[0018] Cooling water temperature: The inlet and outlet water temperatures of the main engine cooling system, measured in degrees Celsius (°C). Too high or too low a cooling water temperature will affect the performance and life of the main engine;

[0019] Vibration and noise: The vibration and noise levels of the host, measured in decibels (dB). Excessive vibration and noise indicate wear or failure of mechanical components.

[0020] Furthermore, in step S3, the parameter rationality analysis is specifically performed in the following manner:

[0021] Comparison with standard values: Compare the actual measured parameter values ​​with the design standard values ​​of the ship's main engine, the reference values ​​provided by the manufacturer, or the industry standards. If the actual values ​​deviate significantly from the standard values, it indicates that there is a problem with the main engine;

[0022] Trend analysis: Observe the changing trend of parameter values ​​over time. If a parameter value continues to rise or fall, it indicates that the host has a potential failure or performance degradation trend;

[0023] Correlation analysis: Analyze the correlation between different parameters. For example, there is usually a certain positive correlation between fuel consumption rate and power; exhaust temperature is closely related to the status of the fuel injection system and cooling system. Through correlation analysis, abnormal parameters and their possible causes can be identified;

[0024] Historical data comparison: Compare the currently measured parameter values ​​with the host's historical operating data to identify host performance trends and potential problems.

[0025] Furthermore, in step S4, the debugging software of the debugging computer provides a parameter modification interface, and the user can adjust the parameter value according to actual needs and save the modified parameter settings.

[0026] Furthermore, the specific operation of step S5 is: selecting the data file to be copied, transferring the data to the external storage device through the USB interface, and completing the data copy and backup operation.

[0027] Furthermore, the signal cable has a USB plug, and the USB signal cable is connected to the USB interface of the host computer and the embedded USB socket and signal cable on the control console. When an external USB device (such as a computer, USB flash drive, mouse and keyboard) needs to be used, it is directly inserted into the embedded USB socket and signal cable to transmit the host operating parameters.

[0028] Furthermore, in addition to being used for transmitting data, the USB interface can also be used to connect a keyboard, mouse and other extended USB devices.

[0029] The present invention provides a USB interface for transmitting data at the PMI of a centralized control console, which has the following beneficial effects:

[0030] The present invention can directly provide a USB interface on the centralized control table, which is convenient for debugging personnel and crew members to transmit data with the host system at any time. Through this USB interface, the host operating parameters can be easily viewed and modified, especially during the operation or debugging of the ship's host. When the host-related operating parameters are unreasonable, such as the critical speed, the car clock speed setting is inaccurate and needs to be modified, it can be directly changed through this solution's USB interface, and after the host debugging is completed, the USB interface can also be used to copy data directly to subsequent ships of the same series. In addition, when the USB interface is not used for data transmission, it can also be connected to a keyboard, mouse and other extended USB devices, which greatly improves the convenience and efficiency of operation. This design not only meets the needs of the ship's host to transmit data externally, so that the host can debug, analyze problems, and update software, but also ensures the normal and efficient operation of the host, analyzes data in advance, and prevents accidents, thereby ensuring the safe operation of the ship's host.

[0036] like Figures 1-4 As shown, a USB interface for transmitting data at the PMI of the centralized control console includes an embedded USB socket and a signal cable. The embedded USB socket and signal cable serve as interfaces for data transmission and are arranged on the table where the screen of the host computer of the centralized control console is located. The signal cable has a USB plug, and the USB signal cable is connected to the USB interface of the host computer and the embedded USB socket and signal cable on the centralized control console. When an external USB device (such as a computer, U disk, mouse and keyboard) needs to be used, it is directly inserted into the embedded USB socket and signal cable to transmit the host operating parameters. The USB interface is suitable for the operation or debugging process of the ship host.

Parameter analysis and adjustment: Check the host operating parameters, such as speed, temperature, pressure, etc., on the debugging computer to analyze whether the parameters are reasonable; the debugging computer runs a special analysis software that can display and record the host operating parameters in real time and provides parameter adjustment functions.

[0040] In this embodiment, the host operating parameters specifically include:

[0041] Speed: The rotational speed of the host, measured in revolutions per minute (rpm), used to measure the host's output power and performance;

[0042] Power: The mechanical power output of the main engine, measured in kilowatts (kW) or horsepower (hp), reflecting the workload and efficiency of the main engine;

[0045] Lubricating oil pressure: The pressure of the main engine lubrication system, measured in bar or megapascals (MPa). Insufficient lubricating oil pressure can lead to poor lubrication and mechanical wear.

[0046] Cooling water temperature: The inlet and outlet water temperatures of the main engine cooling system, measured in degrees Celsius (°C). Too high or too low a cooling water temperature will affect the performance and life of the main engine;

[0047] Vibration and noise: The vibration and noise levels of the host, measured in decibels (dB). Excessive vibration and noise indicate wear or failure of mechanical components.

[0048] In this embodiment, the parameter rationality analysis specifically adopts the following method:

[0049] Comparison with standard values: Compare the actual measured parameter values ​​with the design standard values ​​of the ship's main engine, the reference values ​​provided by the manufacturer, or the industry standards. If the actual values ​​deviate significantly from the standard values, it indicates that there is a problem with the main engine;

[0050] Trend analysis: Observe the changing trend of parameter values ​​over time. If a parameter value continues to rise or fall, it indicates that the host has a potential failure or performance degradation trend;

[0051] Correlation analysis: Analyze the correlation between different parameters. For example, there is usually a certain positive correlation between fuel consumption rate and power; exhaust temperature is closely related to the status of the fuel injection system and cooling system. Through correlation analysis, abnormal parameters and their possible causes can be identified;

[0052] Historical data comparison: Compare the currently measured parameter values ​​with the host's historical operating data to identify host performance trends and potential problems.

[0053] S4. Parameter Modification and Saving: If the host operating parameters are found to be unreasonable, such as inaccurate critical speed or clock speed settings, modify the parameters directly on the debugging computer through the USB interface. In this step, the debugging computer's debugging software provides a parameter modification interface, allowing users to adjust parameter values ​​according to actual needs and save the modified parameter settings.

[0054] S5. Data Copy and Backup: After the main engine commissioning is complete, copy the main engine operating data to a USB flash drive or other storage device via the USB interface for subsequent use or backup on ships in the same series. This step involves selecting the data file to be copied and transferring the data to the external storage device via the USB interface to complete the data copy and backup operation.

[0055] S6. Disconnect and organize: After completing all operations and ensuring that data transfer is complete and there are no ongoing transfer tasks, safely unplug external USB devices and organize all devices and cables to avoid damaging the interface or devices.
