Description

Technical Field

[0001] The present invention relates to the technical field of a one-man bridge, and more particularly to a one-man bridge alarm system for a crude oil carrier and a method of using the same. Background Art

[0002] The one-man bridge system, as the core navigation control unit of large crude oil tankers, is an information-integrated bridge system. It relies on a workstation to receive and process a variety of key navigation information such as main engine speed, navigation speed, ship position, rudder angle, heading, wind speed and direction, water depth, radar warning signals, etc. It automatically completes the navigation plan through electronic charts, radar, GPS, automatic steering and automated monitoring and alarm systems. It has a high level of automation design, can effectively improve navigation efficiency, reduce manpower operating costs, and significantly enhance driving safety. It has become the mainstream configuration of modern large crude oil tankers. In practical applications of one-man bridge systems, only one operator is typically assigned to perform all operational tasks. The system integrates multiple functional consoles, including a navigation control station, traffic monitoring station, command station, steering station, safety monitoring station, and emergency operation station. These consoles are typically located horizontally along the bridge to accommodate information processing and equipment layout requirements. During navigation, operators must frequently switch between consoles to perform operations and observe data, depending on the phase of navigation and mission requirements. For example, switching from the steering station to the traffic monitoring station corresponding to radar alerts, or from the command station to the emergency operation station to handle emergencies. However, in existing one-man bridge systems, operators rely entirely on walking to move between multiple operating stations. This not only results in low efficiency—especially in emergency situations (such as when radar detects an obstacle and requires rapid course adjustment)—manual movement is difficult to meet the rapid response requirements and places high demands on the operator's physical fitness and operational proficiency. Prolonged, high-frequency movement can easily lead to operator fatigue, increasing the risk of operational errors. This prevents the full realization of the intelligent and automated advantages of one-man bridges.

[0003] Therefore, in order to solve the above technical problems, the present invention provides a crude oil carrier one-man bridge alarm system and a method of using the same. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention aims to provide a one-man bridge alarm system for crude oil carriers.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a one-man bridge alarm system for a crude oil carrier, comprising: The mechanical execution module includes a platform, a seat, and a crossbar. The seat is arranged on the platform, and a transverse drive mechanism drives the platform to move transversely through the crossbar. A longitudinal drive mechanism is arranged between the platform and the seat, and the longitudinal drive mechanism drives the seat to move longitudinally on the platform. An operation interaction module, used by operators to input commands and obtain system status, includes an armrest control panel and a touch screen on the seat. The armrest control panel integrates a joystick and multiple buttons, which can send control signals, and the touch screen can display the current seat position. The control module is responsible for receiving control signals and converting them into operation instructions, performing logical operations, and driving mechanical mechanisms. The control module can control the mechanical execution module to perform operations based on the control signals sent by the operation interaction module; A safety protection module is used to ensure operational safety and avoid accidental touches and equipment failures. The safety protection module intercepts operation instructions when the operator accidentally touches a button; A storage module capable of recording seat position data and fault logs; The control module also includes a communication unit, which communicates with the central control system of the one-man bridge building and receives linkage operations: When the central control system of the one-man bridge detects that an operation console needs to be operated, it generates a signal and sends it to the main controller through the communication unit; The main controller receives the instruction, queries the mapping table to confirm the number corresponding to the console, and controls the yellow light of the button to flash and the buzzer to flash synchronously, prompting the operator to press the button; After the button is pressed, the main controller detects the signal, stops the yellow light and buzzer from flashing, switches to green flashing, and drives the seat to move horizontally and vertically to the corresponding operating table.

[0006] Furthermore, a plurality of universal wheels are provided on the platform, and a buffer device is provided between the universal wheels and the platform; and the cross bar is connected to the platform via a hinge seat.

[0007] Furthermore, the control module includes a main controller, which has logical operation, position control and fault handling functions, stores and calls mapping table data, and the mapping table associates buttons with instructions to control the coordinated operation of various modules; The signal acquisition unit includes a digital input module and an analog input module, wherein the digital input module is physically connected to the key and can acquire the signal output by the key, and the analog input module is physically connected to the joystick and can acquire the signal output by the joystick; the signal acquisition unit sends the acquired control signal to the main controller; The driving unit receives the instruction of the main controller and drives the transverse driving mechanism and the longitudinal driving mechanism to operate.

[0008] Furthermore, the safety protection module includes an anti-accidental touch unit, which starts a window period after a key is pressed. If the key is pressed again within the window period, the main controller will generate an operation instruction and send it to the drive unit; The limit unit includes a limit switch, which is respectively set at the lateral left limit, the lateral right limit, the longitudinal front limit, and the longitudinal rear limit; when the limit switch is triggered, the drive in the corresponding direction is immediately stopped; Emergency stop unit, the buttons include an emergency stop button. When the emergency stop button is pressed, the horizontal drive mechanism and the longitudinal drive mechanism stop running and need to be rotated to reset the emergency stop button before restarting; The fault alarm unit includes a buzzer and an alarm pop-up window. When a fault occurs, the buzzer emits a sound signal and the touch screen displays the fault code.

[0009] Furthermore, a light source is integrated in the button. When the button is not associated with the mapping table, the light source in the button is off. After the button is associated, a constant green light is displayed, and the instruction corresponding to the button is constantly lit in red when executed.

[0010] Furthermore, the following calibration method is also included: The main controller controls the movement of the lateral drive mechanism, driving the seat to move toward one end along the linear guide rail until the travel switch on the lateral left limit is triggered; The main controller records the current horizontal coordinate as the horizontal origin, stops the horizontal movement, and completes the horizontal calibration; The main controller controls the movement of the longitudinal drive mechanism, driving the seat to move longitudinally until the travel switch on the longitudinal front limit is triggered; The main controller records the current vertical coordinate as the vertical origin, stops the vertical movement, and completes the vertical calibration.

When the one-man bridge system is in an emergency condition, an alarm command will be sent to the alarm system through the communication unit. The operator confirms whether to execute the alarm command according to the prompt. After confirming to execute the alarm command, the mechanical execution module can quickly drive the operator to move and quickly move to the corresponding operating table to perform operations. It can improve the operator's response speed and handle sudden situations. In conjunction with the one-man bridge system, it can achieve the purpose of high intelligence, automation and rapid response. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In addition, the terms "first," "second," and so on, used in this disclosure are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referenced. Thus, a feature specified as "first" or "second" may explicitly or implicitly include at least one such feature.

Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0020] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0021] like Figures 1 to 2 As shown, the present invention provides a one-man bridge alarm system for crude oil carriers and a method for using the same. The seat system includes a mechanical execution module, a control module, an operation interaction module, a safety protection module and a storage module. The modules work together to achieve precise adjustment and intelligent control of the seat 2.

[0022] The mechanical execution module includes the seat 2, the transverse drive mechanism 4, and the longitudinal drive mechanism 5, which is used to control the seat 2 to achieve transverse and longitudinal movement. Specifically, it includes the following: The system also includes a platform 1, on which a seat 2 is mounted. The platform 1 is connected to the seat 2 via a longitudinal drive mechanism 5, and to a transverse drive mechanism 4 via a crossbar 3. The transverse drive mechanism 4 is located below the operating table. Compared to driving the seat 2 via a slide rail, locating the transverse drive mechanism 4 below the operating table avoids damage to the floor, does not hinder the operator's movement, and prevents impurities from clogging the rails and causing the seat 2 to become stuck.

[0023] Through the transverse driving mechanism 4, the platform 1 can drive the seat 2 to move between the transversely arranged operating tables, and quickly move to the corresponding operating table according to the needs of the operator.

[0024] The lateral drive mechanism 4 can be a screw structure, such as one driven by a servo motor to move a ball screw. It includes a ball screw, a servo motor, a planetary reduction gearbox, and a linear guide. The servo motor drives the ball screw through the reduction gearbox, which in turn drives a drive slider threadedly connected to the screw along the linear guide to achieve lateral adjustment of the seat 2. Generally speaking, the distance between operating tables is 5 to 10 meters, so a lateral movement of 5 to 12 meters is required. The length of the ball screw is selected based on actual needs and is mounted on the bottom of each operating table via a bearing. The servo motor's drive speed can be adjusted between 10 and 20 centimeters per second and can be adjusted as needed to achieve a balance between comfort and efficiency.

[0025] Because different operating tables have different specifications and control methods, the operator's position will also vary when operating different operating tables. A transverse drive mechanism 4 moves the seat 2 to the corresponding operating table, and the longitudinal drive mechanism 5 adjusts the distance between the seat 2 and the operating table. This allows for rapid operator movement and response, adapting to the technical characteristics of a one-person bridge.

[0026] The longitudinal drive mechanism 5 can be a drive slide or an electric push rod. Since the sizes of each operating table are basically unified, the longitudinal distance that the longitudinal drive mechanism 5 needs to adjust is usually between 10 cm and 50 cm. Therefore, the longitudinal drive mechanism 5 only needs to be fine-tuned.

[0027] Furthermore, because a ship is subject to pitching and vibration at sea, platform 1 is equipped with a hinge 7, which is hinged to crossbar 3, allowing platform 1 and crossbar 3 to move relative to each other to accommodate the ship's swaying. To enhance the support of platform 1, multiple universal wheels 6 are installed beneath it, providing support and relieving pressure from crossbar 3. A buffer device 8 is also installed between the universal wheels 6 and platform 1 to mitigate the ship's turbulence.

[0028] The operator interaction module is used to input commands and obtain system status. It includes an armrest control panel and touchscreen on seat 2. The armrest control panel integrates a joystick (X-axis horizontal control, Y-axis vertical control, with center reset) and multiple buttons, which can generate control signals. The buttons are categorized by function, including shortcut keys, recall keys, storage keys, calibration keys, emergency stop keys, mode keys, and standby keys. Each keyboard has its own three-color light source. Keys are matched using a mapping table. When a key is inactive, the light source is off. After a key is matched, the light source illuminates green. The key illuminates red when the matched operation is in progress and flashes yellow when the key is in a linked state.

[0029] Touch screen: can display the current position of seat 2, mapping table configuration interface, scene switching options, fault alarm and other information, and supports administrator password login for parameter configuration.

[0030] The control module is responsible for receiving control signals, converting them into corresponding operating instructions, performing logical operations, and driving the mechanical mechanisms. It comprises a main controller, a signal acquisition unit, a drive unit, and a communication unit. The main controller performs logical operations, position control, and fault handling, stores and accesses mapping table data, and controls the coordinated operation of the various modules. The signal acquisition unit includes a digital input module and an analog input module. The digital input module is physically connected to the buttons and collects their output signals, while the analog input module is physically connected to the joystick and collects its output signals. These collected signals are then transmitted to the main controller.

[0031] The drive unit is physically connected to the transverse motor driver and the longitudinal driver, receives instructions from the main controller to drive the transverse driver or the longitudinal driver, and has a built-in overload protection function.

[0032] The communication unit communicates with the central control system of the one-man bridge building and receives linkage operation instructions.

[0033] The safety protection module is used to ensure operational safety and avoid accidental touch and equipment failure. It includes an anti-accidental touch unit, a limit unit, an emergency stop unit and a fault alarm unit.

[0034] Anti-accidental touch unit: After the operator presses a button, the button flashes green and a 1 to 3 second window period is started. The operator must release the button and press it again within the window period for the command to take effect. The pressed button will flash green within the window period. Limit unit: includes 4 travel switches, which are set at the lateral left limit (Xs), lateral right limit (Xm), longitudinal front limit (Ys), and longitudinal rear limit (Ym). They correspond to the minimum and maximum travel distances of the lateral drive mechanism 4 and the minimum and maximum travel distances of the longitudinal drive mechanism 5, respectively. Once triggered, the drive in the corresponding direction (lateral or longitudinal) is immediately stopped. At the same time, the main controller has built-in soft limit switches. Emergency stop unit: When the emergency stop button is pressed, the safety relay immediately cuts off the drive enable, and all drives stop. The emergency stop button must be rotated to reset before restarting; Fault alarm unit: includes a buzzer and an alarm pop-up window. When a fault occurs, the buzzer emits a sound signal and the touch screen displays the fault code and cause (such as 1001: horizontal motor overload, 1002: longitudinal motor overload, 1003: horizontal overtravel, etc.).

[0035] The storage module stores mapping table scenario data (such as "near-sea sailing", "ocean sailing", and "port mooring" scenarios), seat 2 position data (the location of the storage key record), and fault logs, and supports data import / export.

[0036] Among them, the system will be initialized and calibrated after power-on. The process is as follows: After a delay (to avoid power-on shock), the main controller controls the lateral drive to rotate in the opposite direction, driving seat 2 to move left along the linear guide rail until the lateral left limit travel switch (SQ1) is triggered. After triggering SQ1, the main controller records the current lateral coordinate as 0.0m, stops the lateral motor, and completes the lateral calibration; Then the main controller controls the longitudinal motor driver to drive the longitudinal motor to rotate forward, driving the seat 2 to move forward along the longitudinal guide rail until the longitudinal front limit travel switch (SQ3) is triggered; After triggering SQ3, the main controller records the current longitudinal coordinate as 0.0m, stops the longitudinal motor, and completes the longitudinal calibration; After the calibration is completed, the HMI displays "Calibration successful" and the system enters the standby state, waiting for operation instructions.

[0037] The method for editing the mapping table is as follows (taking button number 2 as an example): The operator clicks "System Settings" on the main interface of the touch screen, enters the administrator password, and selects "Mapping Table Configuration". The system enters the configuration mode, suspends normal operations, and the touch screen displays the current mapping information of the button (button number, target coordinates, function type, and enable status); The operator clicks "Button No. 2" (originally corresponding to X=1.2m, Y=0.4m), and the "Edit Mapping" pop-up window pops up. In the "Target Horizontal Coordinate" input box, change it to "1.3000" and click "Preview"; The main controller receives the preview command and controls seat 2 to move to X=1.3000m, Y=0.4000m for the operator to confirm the position; After confirmation, the operator clicks "Save", and the main controller updates the target horizontal coordinate of "Button No. 2" in the mapping table data block to 1.3000m, and keeps the enable state TRUE; The operator clicks "Exit Configuration" and the system resumes normal operation. Subsequently, the operator presses the shortcut key of the operating console 2 and seat 2 moves to X=1.3000m and Y=0.4000m.

[0038] You can also set scene modes in the main controller, for example (taking "ocean voyage" to "port mooring" as an example): The operator clicks "Scene Switch" on the main interface of the touch screen and selects "Port Berthing Scene" (Scene Index 1); The main controller receives the scene index, reads the mapping table data corresponding to the "port berthing scene" from the storage module, and overwrites the current mapping table data block content (for example, the target coordinate of the shortcut key on console 5 is changed from X=4.8m to X=4.9m to adapt to the operation requirements during port berthing); After the mapping table is updated, the main controller sends a feedback message "Scene switch successful" to the touch screen, and the touch screen updates and displays the current mapping information of all buttons. The system responds to operation instructions based on the new mapping table.

[0039] In addition, since the communication unit is connected to the central control system of the one-man bridge, when the central control system of the one-man bridge detects that an emergency operation is required on a certain operating console, an alarm instruction is generated and sent to the main controller by the communication unit; The main controller receives the alarm command, queries the mapping table to confirm the number corresponding to the console, controls the high and low levels in the button to alternate, and makes the button flash yellow to alert the operator, and controls the buzzer to flash synchronously; When the button is pressed, the main controller detects the signal, stops flashing yellow and the buzzer, and switches to flashing green. The subsequent process is the same as the button-controlled movement and is not detailed here. Seat 2 moves laterally and vertically, quickly reaching the corresponding operating console, allowing the operator to quickly operate the console and respond quickly to the triggered alarm. Once the operator operates the console, the alarm is released.

[0040] In addition, a cancel button is included. After pressing the cancel button, the alarm command is cancelled.

[0041] Among them, the operation of troubleshooting (taking the horizontal drive overload as an example, the vertical drive is the same): The lateral driver triggers the driver overload protection due to excessive load, and the driver's fault output port sends a high-level fault signal to the port of the main controller; The main controller receives the fault signal and immediately sends a "stop" command to the lateral drive, while controlling the digital output module to cut off all drive enable signals; The main controller writes "fault code 1001 (transverse drive overload)" into the fault data block and sends it to the touch screen through communication. The touch screen pops up a red alarm window, displaying "Transverse drive overload, please check the load"; At the same time, the main controller outputs a continuous high level to the port, starting the buzzer to sound continuously; After the maintenance personnel eliminate the overload fault, the operator clicks "Fault Confirmation" on the touch screen, the main controller stops the buzzer, clears the fault status, and the system returns to standby.

[0042] Joystick control operation: The operator presses the "joystick mode switch key", the touch screen displays "joystick mode is on", and the key is solid green; When the operator pushes the joystick X-axis to the left, the AI0 port of the analog input module detects a 0-5V analog signal and transmits it to the main controller. The main controller converts the analog signal into a lateral movement command (for example, AI0 = 2.5V corresponds to a speed of 0.15m / s) and sends "reverse" and "0.15m / s speed" commands to the lateral motor driver. Seat 2 moves in the direction and force of the joystick push. When the operator releases the joystick, it automatically returns to the center, the AI0 port signal returns to 5V (neutral position), the main controller sends a "stop" command, and seat 2 stops moving.

[0043] In addition, the operator adjusts seat 2 to the target position and presses the "Store Key". The touch screen pops up a "Select Storage Position" window, and the operator selects "Store Position 1". The main controller reads the current coordinates of seat 2 and stores them in the "Store Position 1" address of the storage module. The touch screen pops up "Store Completed" to indicate that the storage is complete. Regarding position call, the operator presses the "position call key 1", and the main controller reads the coordinates of the "storage bit 1" from the storage module. The subsequent process is consistent with the button control movement. Seat 2 moves to the target position and the call key LED is always green.

[0044] In summary, the above implementation scheme can achieve the following effects: High efficiency: The hidden lateral / longitudinal drive mechanism 5 enables automatic adjustment of the seat 2 between multiple operating stations (lateral adjustment time ≤ 30 seconds, longitudinal adjustment time ≤ 16 seconds), eliminating the need for manual movement and improving operator switching efficiency. Flexibility: Through mapping table editing and scene switching functions, the console position requirements of different navigation scenarios (such as offshore, offshore, and port) can be quickly adapted without reconfiguring the mechanical structure; Safety: The system integrates four safety mechanisms, including anti-accidental touch, limit protection, emergency stop, and fault alarm, to avoid safety risks caused by incorrect operation and equipment failure, and complies with marine safety standards.

[0045] It can quickly move operators according to needs and complete efficient transportation, allowing operators to respond quickly, thereby achieving one-person control and providing strong support for the one-person bridge technology.

[0046] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any ordinary technician in this industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with this profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the scope of protection of the technical solution of the present invention.
