Description

Technical Field

[0001] This invention relates to the field of marine technology, specifically to a universal alarm model switching method for berthing and refueling. Background Technology

[0002] When a vessel is berthing or refueling, if the general alarm is triggered according to the conventional model, the alarm sound generated by the ship's general alarm system for non-emergency faults may cause panic among ship and shore personnel, unnecessary emergency response actions by port authorities, and losses such as suspension of ship operations. However, if all alarms of the general alarm system are blindly blocked, causing the vessel and port to be unable to respond in a timely manner, it violates the requirements of the regulations. Summary of the Invention

[0003] The purpose of this invention is to provide a universal alarm model switching method for berthing and refueling, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a universal alarm model switching method for berthing and refueling, wherein the universal alarm model switching method is controlled by a switching system, the system comprising: Operation input switching module: Used by the operator to send a mode switching signal to the control core module according to the vessel's status to switch the system operating mode (normal mode: the general alarm button (berthing state) is not pressed, the button is in the open state, no signal input is sent to the general alarm system control cabinet, at this time, the new control loop does not operate, the general alarm system maintains the original working mode, all alarms (critical and non-critical) are triggered normally, the audible and visual alarm devices work normally, and the operator can receive all equipment abnormal information in a timely manner; berthing mode: the control loop cuts off the audible and visual output loop of non-critical alarms, non-critical alarms no longer trigger audible and visual prompts, but can be displayed on the alarm panel in a low priority state (for easy fault tracing later)). Alarm self-test control module: used to perform preset periodic self-tests on system control components and structures such as power supply, shielding circuit continuity, and the integrity of critical alarm direct-through circuits; Alarm control module: It is responsible for receiving input signals and executing the shielding logic according to the instructions, and distinguishing between critical and non-critical alarm operation according to the instructions; Fault detection module: It is used to automatically receive the detection data in the alarm control module when the alarm self-test control module is running, and automatically determine whether the detected data exceeds the safety threshold range. If the detected data exceeds the safety threshold range, it indicates that a fault has occurred. At this time, it automatically sends a command to the corresponding warning light on the alarm system control cabinet to issue an alarm to the maintenance personnel. If the detected data is within the safety threshold range, it indicates that there is no fault. At this time, the command is sent to the alarm self-test control module to record the data for subsequent personnel to retrieve and check. Berthing status monitoring module: When the system switches to berthing mode, it will automatically start to monitor in real time whether the vessel has started to depart. If the vessel has started to depart, it will automatically send a command to the alarm control module to activate non-critical alarms. If the vessel has not yet departed, no command will be sent. Alarm output module: Used to automatically receive instructions sent by the alarm control module, and responsible for outputting alarm signals or shielding non-critical alarm outputs according to the sent instructions.

[0005] Furthermore, the alarm control module includes an instruction receiving unit for automatically receiving instructions sent by the alarm self-test control module, the operation input switching module, and the berthing status monitoring module; and a berthing status discrimination unit for judging the real-time status of the vessel based on the data information sent by the berthing status monitoring module, and sending a signal to the corresponding control unit to activate the alarm based on the judged vessel status.

[0006] Furthermore, the alarm control module also includes a non-critical alarm control unit and a command output unit. The non-critical alarm control unit consists of: auxiliary pump alarms (fault alarms and low liquid level alarms for auxiliary equipment such as cooling water pumps, sanitary water pumps, fresh water pumps, and sewage pumps); ventilation equipment alarms (fault alarms and overload alarms for conventional ventilators, blowers, and exhaust fans); non-critical liquid level alarms (ordinary high and low liquid level alarms for non-hazardous compartments such as living quarters and storage compartments, excluding overflow and leakage); secondary electrical alarms (fault alarms for non-core electrical circuits, lighting systems, and small auxiliary electrical equipment); and other non-critical alarms (status alarms for auxiliary equipment that do not involve safety and minor abnormality alarms). The command output unit is used to automatically send commands to the alarm output module and the berthing status monitoring module.

[0007] Furthermore, the alarm control module also includes a key safety alarm control unit: consisting of fire alarms triggered by manual fire alarm buttons, smoke detectors, and temperature detectors, as well as fire protection system abnormality alarms; gas leak alarms: alarms for leaks of combustible and toxic gases, and gas detection equipment malfunction alarms; dangerous liquid level alarms: alarms for dangerous high liquid levels and overflows in key compartments such as cargo holds, engine rooms, and fuel tanks; core equipment alarms: security alarms and emergency shutdown alarms for core power equipment such as main engines and auxiliary engines; and other key alarms: carbon dioxide release warnings, emergency power failure alarms, and personnel emergency call alarms.

[0008] Furthermore, when only the critical safety alarm control unit in the alarm control module sends an instruction (i.e., the vessel is in a berthing and refueling state) to run, a signal is simultaneously sent to the berthing status monitoring module to activate it. When both the critical safety alarm control unit and the non-critical alarm control unit in the alarm control module send instructions (i.e., the vessel is in a sailing state) to run, only the instruction is sent to the alarm output module.

[0009] Furthermore, the alarm self-test control module includes a self-test cycle setting unit, an automatic self-test control unit, and a self-test result recording and output unit. The self-test cycle setting unit is used by staff to set the corresponding self-test cycle time according to the actual situation, such as: one round of self-test every half hour or three rounds of self-test within two hours, etc.

[0010] Furthermore, the automatic self-test control unit is used to control the non-critical alarm control units and critical safety alarm control units in the alarm control module to perform self-testing operations at preset cycles according to instructions, and send the detected data to the fault discrimination module for automatic discrimination processing.

[0011] Furthermore, the self-test result recording and output unit is used to automatically record the data of each self-test of the system and classify and store the recorded data. Then, it automatically generates a curve graph of the corresponding data according to the detection order, and marks the abnormal data curve values.

[0012] Furthermore, the berthing status monitoring module only operates when the critical safety alarm control unit is activated alone, and during operation, it sends monitoring data to the alarm control module in real time to automatically determine the real-time dynamics of the vessel through the berthing status discrimination unit.

[0013] This invention provides a universal alarm model switching method for berthing and refueling, which has the following beneficial effects: 1. This invention, through the setting of an operation input switching module and an alarm control module, enables the method to switch to the corresponding operating mode according to the state of the ship during use. Compared with the conventional general alarm model, it can effectively avoid the operation interruption and panic of ship and shore personnel caused by non-emergency alarms, while ensuring the normal triggering of emergency alarms in dangerous situations, realizing a more intelligent and safer ship berthing / refueling operation mode.

[0014] 2. This invention, through the alarm self-test control module, enables the system to perform self-testing according to the crew's preset time cycle, ensuring that alarm components or circuits can issue timely warnings when malfunctions occur, allowing maintenance personnel to carry out repairs. Furthermore, the berthing status monitoring module allows the system to monitor the ship's status in real time when the crew switches the system to berthing mode, ensuring that non-emergency alarms are activated promptly when the ship starts to depart. This not only improves the applicability of the system but also provides convenience for the crew's actual operation. Attached Figure Description

Detailed Implementation

[0016] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0017] like Figures 1-3 As shown, a general alarm model switching method for berthing and refueling is provided. This general alarm model switching method is controlled by a switching system, which includes: Operation input switching module: Used by the operator to send a mode switching signal to the control core module according to the vessel's status to switch the system operating mode (normal mode: the general alarm button (berthing state) is not pressed, the button is in the open state, no signal input is sent to the general alarm system control cabinet, at this time, the new control loop does not operate, the general alarm system maintains the original working mode, all alarms (critical and non-critical) are triggered normally, the audible and visual alarm devices work normally, and the operator can receive all equipment abnormal information in a timely manner; berthing mode: the control loop cuts off the audible and visual output loop of non-critical alarms, non-critical alarms no longer trigger audible and visual prompts, but can be displayed on the alarm panel in a low priority state (for easy fault tracing later)). Alarm self-test control module: This module performs pre-set periodic self-tests on system control components and structures, such as power supply, shielding circuit continuity, and the integrity of critical alarm direct-through circuits. It includes a self-test cycle setting unit, an automatic self-test control unit, and a self-test result recording and output unit. The self-test cycle setting unit allows operators to set corresponding self-test cycle times based on actual conditions, such as one self-test every half hour or three self-tests within two hours. This allows operators to adjust the self-test cycle according to equipment aging. The automatic self-test control unit controls the non-critical alarm control units and critical safety alarm control units within the alarm control module to perform pre-set periodic self-tests and sends the detected data to the fault diagnosis module for automatic diagnosis. The self-test result recording and output unit automatically records the data from each self-test, categorizes and stores the data, and then automatically generates a graph based on the detected data, marking abnormal data values. This facilitates timely elimination of safety hazards during subsequent periodic inspections by maintenance personnel and provides convenience for their maintenance work. The alarm control module is responsible for receiving input signals and executing masking logic according to instructions. It also distinguishes between critical and non-critical alarm operation based on these instructions. The alarm control module includes an instruction receiving unit, which automatically receives instructions from the alarm self-test control module, the operation input switching module, and the berthing status monitoring module; and a berthing status discrimination unit, which determines the vessel's real-time status based on data from the berthing status monitoring module and sends a signal to the corresponding control unit to activate the alarm. This ensures that non-critical alarm control units automatically activate and trigger alarms when the vessel departs. The alarm structure is open, effectively reducing the number of steps required for operation. The alarm control module also includes non-critical alarm control units and command output units. The non-critical alarm control units include: auxiliary pump alarms (fault alarms and low liquid level alarms for auxiliary equipment such as cooling water pumps, sanitary water pumps, fresh water pumps, and sewage pumps); ventilation equipment alarms (fault alarms and overload alarms for conventional ventilators, blowers, and exhaust fans); non-critical liquid level alarms (general high and low liquid level alarms for non-hazardous compartments such as living quarters and storage compartments, excluding overflow and leakage); and secondary electrical alarms (for non-core electrical circuits, lighting systems, and small...). The alarm control module includes: fault alarms for auxiliary electrical equipment; other non-critical alarms: status alarms for auxiliary equipment that do not involve safety, and minor abnormal alarms; and a command output unit: used to automatically send commands to the alarm output module and the berthing status monitoring module. The alarm control module also includes critical safety alarm control units: fire alarms triggered by manual fire alarm buttons, smoke detectors, and temperature detectors, and fire protection system abnormal alarms; gas leak alarms: leak alarms for combustible gases and toxic and harmful gases, and gas detection equipment fault alarms; dangerous liquid level alarms: dangerous high liquid level and overflow alarms for critical compartments such as cargo holds, engine rooms, and fuel tanks; core equipment alarms: security alarms and emergency shutdown alarms for core power equipment such as main engines and auxiliary engines; and other critical alarms: carbon dioxide release warnings, emergency power supply failure alarms, and personnel emergency call alarms. When only the critical safety alarm control unit in the alarm control module sends a command (i.e., the vessel is in berthing and refueling state), a signal is simultaneously sent to the berthing status monitoring module to activate it. When both the critical safety alarm control unit and non-critical alarm control unit in the alarm control module send commands (i.e., the vessel is in sailing state), only the command is sent to the alarm output module. Fault detection module: It is used to automatically receive the detection data in the alarm control module when the alarm self-test control module is running, and automatically determine whether the detected data exceeds the safety threshold range. If the detected data exceeds the safety threshold range, it indicates that a fault has occurred. At this time, it automatically sends a command to the corresponding warning light on the alarm system control cabinet to issue an alarm to the maintenance personnel. If the detected data is within the safety threshold range, it indicates that there is no fault. At this time, the command is sent to the alarm self-test control module to record the data for subsequent personnel to retrieve and check. Berthing Status Monitoring Module: When the system switches to berthing mode, it automatically starts to monitor in real time whether the vessel has started to depart. If the vessel has started to depart, it automatically sends a command to the alarm control module to activate non-critical alarms. If the vessel has not yet departed, no command is sent. The berthing status monitoring module only runs when the critical safety alarm control unit is activated alone. During operation, it sends monitoring data to the alarm control module in real time to automatically determine the vessel's real-time dynamics through the berthing status discrimination unit. Alarm output module: Used to automatically receive instructions sent by the alarm control module, and responsible for outputting alarm signals or shielding non-critical alarm outputs according to the sent instructions.

[0018] In summary, combining Figures 1-3 As shown, the working principle of the general alarm model switching method used during berthing and refueling is as follows: First, when the ship is berthing and refueling, the crew presses the general alarm button on the bridge control panel, which causes the operation input switching module to receive the instruction and automatically switch the system to berthing mode. Then, the operation input switching module sends an instruction to the alarm control module. At this time, the instruction receiving unit in the alarm control module receives the instruction and sends a signal to the non-critical alarm control unit and the critical safety alarm control unit, causing the non-critical alarm control unit to shut down, while the critical safety alarm control unit continues to operate normally. Then, the instruction output unit sends the instruction to the alarm output module and the berthing status monitoring module, causing the corresponding alarm mechanism in the alarm output module to stop operating, while the berthing status monitoring module starts operating to monitor the ship's operating status in real time and send the monitoring data to the alarm control module in real time. At this time, the berthing status discrimination unit automatically analyzes and discriminates the monitoring data to determine the ship's status. Secondly, if the berthing status determination unit determines that the ship has started to operate and left the port, the berthing status determination unit sends a command to the non-critical alarm control unit, thereby causing the alarm output module to control the corresponding alarm mechanism to start running again. Finally, the operator sets the system self-test cycle through the self-test cycle setting unit in the alarm self-test control module. When the preset self-test cycle time is reached, the automatic self-test control unit starts running to control the alarm control module to perform self-tests on the power stability of the system hardware, the operating status of the control logic, the continuity of the docking shielding circuit, and the integrity of the key alarm direct-through circuit. Since this self-test is a silent background test, without sound, light, or prompts, it does not affect operation. Then, the self-test result is sent to the fault judgment module for judgment through the self-test result recording and output unit. If the test data exceeds the safety threshold range, it indicates a fault. At this time, an automatic command is sent to the corresponding warning light on the alarm system control cabinet to issue an alarm to the maintenance personnel. If the test data is all within the safety threshold range, it indicates no fault. At this time, a command is sent to the alarm self-test control module to record the data for later retrieval and inspection.

Many modifications and variations will be apparent to those skilled in the art.
