Technical Field

[0001] The present invention relates to the field of ship safety technology, in particular to a cable-laying ship safety monitoring and integrated alarm system and a working method thereof. Background Art

[0002] Cable laying vessels are special vessels designed for laying and maintaining submarine cables or pipelines. They play a key role in laying submarine cables and pipelines, ensuring the reliable transmission of electricity, communications and resources. Cable laying vessels play an irreplaceable role in modern marine engineering. Their advanced technology and equipment ensure the safe and efficient laying and maintenance of submarine cables and pipelines, which is of great significance to global communication networks, energy supply and marine scientific research. In order to improve the working life and work efficiency of cable laying vessels and ensure the normal operation of cable laying vessels, it is essential to install an alarm system on board.

[0003] Traditional ship alarm systems are usually scattered in various areas and work independently, which leads to complex management and slow response. It is not easy to quickly find problems, especially in emergency situations. For fiber optic cable laying ships, there are four relatively independent systems: cable cabin alarm, personnel safety alarm, high voltage alarm and tension alarm. In traditional detection and alarm systems, these four systems are scattered in different monitoring and control areas. Such a layout not only increases the complexity of management, but also requires crew members to frequently switch multiple system interfaces during maintenance and operation, increasing the risk of errors and response time.

[0004] In the document CN 219831850 U, a truck maintenance intelligent identification and integrated alarm system is disclosed, including a ground central substation, a truck, a helmet, an RFID unit, an on-site control box and a PLC controller, the PLC controller includes an LED display screen, a on-site control box is provided at the bottom of the truck, the on-site control box includes a touch display screen, and the truck and the helmet are both provided with an RFID unit. This structure does not unify multiple components when in alarm mode, and cannot perform real-time monitoring.

[0005] Therefore, a new technical solution is needed to solve the above technical problems. Summary of the invention

Through this integrated design, operators can view and process all alarm information on one interface, which greatly simplifies the operation process and reduces the possibility of errors. At the same time, the system can more quickly summarize and analyze data from various sensors, promptly detect abnormal situations and issue alarms, thereby improving response speed and decision-making efficiency.

[0016] By adopting the above technical solution, after the pyroelectric trigger, a secondary detection is performed through the camera. The above method can effectively reduce the power consumption of the camera and improve the detection accuracy. When a person is detected, the control card outputs a high-level signal. When no one is detected, the controller outputs a low level according to the setting. The cable cabin alarm component and the high-voltage alarm component are dry contact inputs. When an alarm is generated, the dry contact is closed. The tension alarm component is connected to the third-party system in the form of RS485 to communicate with the third-party system.

The MCU chip module uses the exponential smoothing method to analyze and calculate the accumulated data, corrects the data, and then learns until the data change rate is within the normal range. The system determines the type of fault based on the abnormal change in the data. If the amplitude of the abnormal change is within the range of equipment failure, personnel safety, and fire failure, it is defined as an emergency alarm, otherwise it is a regular fault alarm; Step 4: Fault information alarm The alarm module receives the data processing results of the data processing module in real time, and executes corresponding alarm tasks according to different fault categories; S41: Sensor failure alarm The sensor alarm in the control center sounds an alarm, and the yellow light on the status indicator board of the corresponding fault area turns on, reminding the staff to perform sensor maintenance; S42: Non-sensor fault alarm For emergency alarms such as equipment / machine failure, personal safety, fire, etc., execute step E421; for abnormal data changes in the cable cabin, high-voltage box, and tow cable tension, execute step E422; E421: Emergency alarm Manually operate the emergency button, and check and handle faults; E422: General fault alarm (1) In case of cable cabin failure, the operation panel rotates to +45°, prompting fault handling.

[0027] The components in the safety monitoring module 01 work in coordination, collect cable cabin data from various operating equipment sensor components 11 arranged in the cable cabin by means of communication, obtain high voltage information by means of dry contact 13 input, obtain personnel safety information by means of two detection methods of pyroelectric human infrared sensor and camera component 12, and obtain tension data directly from the operating equipment control system through the communication network 14; The data processing module 02 includes a PCB control board 20, an input and output interface 21, a data or signal processing software 22 and an interactive device 23. The data or signal processing software 22 includes analysis software and a database, and has data access, intelligent analysis and instruction generation functions. The data or signal processing software 22 in the data processing module 02 performs intelligent analysis and judgment on the data information transmitted from the safety monitoring module 01 to the cable-laying vessel control center 04, and issues corresponding alarm instructions to the integrated alarm module 03 according to different signal states and situations.

[0028] The PCB control board 20 includes an MCU1 chip module 201, an MCU2 chip module 209, a switching switch 202, a power module 203, an IO output module 204, an IO input module 205, a touch screen module 206, a 485 communication module 207, and an Ethernet communication module 208. The MCU1 chip module 201 or the MCU2 chip module 209 in the PCB control board 20 is responsible for sensor fault processing and non-sensor fault processing.

[0029] The MCU chip module 201 is symmetrically fixed on the PCB control board 3, the switching switch 202 is fixed in the middle of the two MCU chips, and the switching switch is composed of a watchdog IC for redundant and disturbance-free switching, so that when the MCU1 chip module 201 fails, the MCU2 chip module 209 participates in the control, and the power module 203 uses a DCDC isolation device VRB2405 power module.

[0030] The MCU2 chip module 209 participates in the control to achieve high-reliability redundancy capability, so that the PCB control board 20 has a safe redundant design. The power module 203 uses a DCDC isolation device VRB2405 power module to convert the DC24V voltage into DC5V and DC3.3V for powering the single-chip microcomputer system, etc.

[0031] The IO output module 204 uses the Hongfa small power relay HF46, the IO input module 205 uses the EL354 bidirectional optocoupler for isolation and is connected to the microcontroller IO, the touch screen module 206 uses a serial port display screen and is connected to the serial port of the microcontroller, the 485 communication module 207 uses the Jinshengyang TDA51S485HC, the input end is connected to the serial port of the microcontroller, and the output end is connected to the TVS protection module, the Ethernet communication module 208 uses the CH9120 Ethernet protocol conversion chip, and CH9120 is connected to the network port transformer and the serial port of the microcontroller.

[0032] like Figure 3-4 As shown, the integrated control box 30 is connected to the selection board 31, the emergency button 32, the alarm lamp column 33, and the status indicator board 34 through signal lines. The integrated control box 30 includes an alarm main board 301, a cable cabin alarm component 302, a personnel safety alarm component 303, a high-voltage alarm component 304, a tension alarm component 305, an Ethernet output component 306, an isolated power supply module component 307, an audible and visual alarm component 308, and an alarm touch screen component 309. The front panel of the integrated control box 30 is provided with start and stop buttons A and B.

[0033] The alarm mainboard 301 collects signals from the cable cabin alarm component 302, the personnel safety alarm component 303 and the high-voltage alarm component 304 through the IO communication method. The alarm mainboard 301 reads the signal of the tension alarm component 305 through the 485 communication method, and sends the collected data and alarm to the Ethernet output component 306 through the SPI / TTL serial port. The isolated power supply module component 307 is connected to the alarm mainboard 301. The alarm mainboard 301 outputs to the sound and light alarm component 308 through the IO output method, and communicates with the alarm touch screen component 309 through the TTL serial port. The alarm mainboard 301 is used to process the camera image and the pyroelectric human infrared sensor data. When the pyroelectric is triggered, secondary detection is performed through the camera.

[0034] After the pyroelectric trigger, secondary detection is performed through the camera. The above method can effectively reduce the power consumption of the camera and improve the detection accuracy. When a person is detected, the control card outputs a high-level signal. When no one is detected, the controller outputs a low-level signal according to the setting.

[0035] The cable cabin alarm component 302 and the high-pressure alarm component 304 are dry contact inputs. When an alarm is generated, the dry contact is closed, and the tension alarm component 305 is connected to the third-party system in the form of RS485 to communicate with the third-party system. MODBUSRTU is used to coordinate and obtain real-time pressure signals. An alarm is generated when the pressure is greater than the set value.

[0036] The selection board 31 has two positions, an emergency button 32, and the warning light column 33 is equipped with green, yellow and red lights, which can be observed in all working areas and cable laying consoles. "Green" means safe and normal operation, and "yellow" is a reminder of safe operation.

[0037] If a worker is tripped by a cable, an inspection is required; "red" indicates personal safety (such as electric shock) or machine failure, and the equipment needs to be stopped immediately; there are multiple status indicator panels 34, which are installed in the cab cable laying console, trenching plow control station, cable machine control room, hangar area, test room and other areas, respectively, to display the fault status of the corresponding area; When the start button of the integrated control box 30 is pressed, the operation indicator light is on and the system starts, and the indicator light goes out when the button is pressed; when the signal of the selection board 31 or the emergency button 32 is input, the red light of the alarm lamp column 33 of the corresponding cable cabin is on, the buzzer sounds, and the red indicator lights of the corresponding areas of all status indicator boards 34 are on; When the selection plate 31 is rotated to +45°, it indicates that the cable cabin may be abnormal, the yellow light of the alarm lamp column 33 of the corresponding cable cabin is on, the buzzer does not sound, and the yellow lights of the corresponding areas of all status indicator panels 34 are on; when the selection plate 31 is rotated to -45°, it indicates that the cable cabin is normal, the green light of the alarm lamp column 33 of the corresponding cable cabin is on, the buzzer does not sound, and the green lights of the corresponding areas of all status indicator panels 34 are on; like Figure 5 As shown, in the system logic processing, the self-learning method is used to process the data. When the data mutates but does not reach the threshold, the system will generate a pre-alarm. The MCU chip module 201 has a built-in large-capacity storage unit, which can record fault information and status information in real time. The system can transmit the data to the local or cloud database through the Ethernet output component 306; the method of data processing by self-learning includes sensor fault processing and non-sensor fault data processing (including cable cabin, high-voltage box, personnel safety, and towing cable tension); Whether the sensor is faulty is determined by judging the detected sensor data based on the MCU1 chip module 201 or the MCU2 chip module 209. If no updated data is obtained within a defined period of time (compared with the previous stored data), it indicates that the sensor itself is faulty. At this time, the system will generate an alarm prompt to warn that the sensor is faulty. Abnormal conditions caused by equipment failures such as cable cabins, high-voltage boxes, personnel safety, and towing cable tension, or endangering operational safety, are attributed to non-sensor fault data processing; the MCU1 chip module 201 or the MCU2 chip module 209 performs differential calculations on the collected non-sensor data in real time, and stores the calculated data change rate in the FLASH. The MCU chip module uses the exponential smoothing method to analyze and calculate the accumulated data, corrects the data, and then learns until the data change rate is within the normal value range. The system determines whether it has reached an alarm state based on the abnormal change in the data, and reminds the user.

After the equipment sensor component 11, the camera component 12, and the multiple dry contacts 13 collect the corresponding information, the information is sent to the cable-laying ship control center 04 set in the bridge of the mother ship in real time through the communication network 14, including the operation status information of the cable cabin operation equipment, the high-voltage signal input by the dry contact, the operation tension of the optical cable, and the safety information of the personnel; Step 3: Data processing and fault classification The data transmitted by the safety monitoring module 01 to the cable-laying vessel control center 04 is intelligently analyzed and judged by the data or signal processing software 22 in the data processing module 02, including correction and learning of the data by differential calculation and exponential smoothing method, and data access and alarm instruction generation. The interactive device 23 provides parameter settings and data information display; S31: Sensor fault handling The MCU1 chip module 201 or the MCU2 chip module 209 judges the detected sensor data, and if no updated data is obtained by comparing with the previous stored data within the defined time length, the system will generate an alarm prompt, and warn the alarm module 03 that the sensor is faulty, and execute S41; S32: Non-sensor fault data processing The MCU1 chip module 201 or the MCU2 chip module 209 performs differential calculation on the collected data in real time, and stores the calculated data change rate in the FLASH. The MCU chip module uses the exponential smoothing method to analyze and calculate the accumulated data, and then learns after correcting the data until the data change rate is within the normal range. The system determines the type of fault based on the abnormal change amount of the data. If the amplitude of the abnormal change amount is within the range of equipment failure, personnel safety and fire failure, it is defined as an emergency alarm, otherwise it is a regular fault alarm; Step 4: Fault information alarm The alarm module 03 receives the data processing results of the data processing module 02 in real time, and executes corresponding alarm tasks according to different fault categories; S41: Sensor failure alarm The sensor alarm 42 of the control center 04 sounds an alarm, and the yellow light of the corresponding fault area status indicator panel 34 turns on, reminding the staff to perform sensor maintenance; S42: Non-sensor fault alarm For emergency alarms such as equipment / machine failure, personal safety, fire, etc., execute step E421; for abnormal data changes in the cable cabin, high-voltage box, and tow cable tension, execute step E422; E421: Emergency alarm Manually operate the emergency button 32, and check and handle the fault; E422: General fault alarm (1) In case of cable cabin failure, the operation selection panel 31 is rotated to +45°, prompting fault handling. After the fault handling is completed, the operation selection panel 31 is rotated to -45°; (2) High-voltage box alarm High voltage is a dry contact input. When an alarm is generated, the dry contact closes to remind you to handle the fault. (3) If the towline tension fails, the fault information will be displayed and the fault will be handled; Step 5: Determine the system operation status If the system is powered off, proceed to step 6. If the system is in operation, repeat steps 2 to 4. Step 6: End.

10. A working method of a cable-laying vessel safety monitoring and integrated alarm system as claimed in claim 1, characterized in that: The following steps are involved: Step 1: System startup Start the integrated control box and initialize it to work status; Step 2: Safety monitoring module collects data The safety monitoring module works to collect data in real time at regular intervals. After the equipment sensor components, camera components, and multiple dry contacts collect the corresponding information, they are sent to the cable-laying ship control center located in the mother ship's bridge in real time through the communication network. The information includes the operating status of the cable cabin operating equipment, the high-voltage signal input by the dry contact, the operating tension of the optical cable, and the safety information of personnel. Step 3: Data processing and fault classification The data transmitted to the cable-laying ship control center by the safety monitoring module is intelligently analyzed and judged by the data or signal processing software in the data processing module, including correction and learning of the data by differential calculation and exponential smoothing method, and data access and alarm instruction generation. The interactive device provides parameter settings and data information display; S31: Sensor fault handling The MCU1 chip module or the MCU2 chip module judges the detected sensor data, and if no updated data is obtained by comparing with the previous stored data within the defined time length, the system will generate an alarm prompt, and warn the alarm module that the sensor is faulty, and execute S41; S32: Non-sensor fault data processing The MCU1 chip module or the MCU2 chip module performs differential calculation on the collected data in real time, and stores the calculated data change rate in the FLASH. The MCU chip module uses the exponential smoothing method to analyze and calculate the accumulated data, corrects the data, and then learns until the data change rate is within the normal range. The system determines the type of fault based on the abnormal change in the data. If the amplitude of the abnormal change is within the range of equipment failure, personnel safety, and fire failure, it is defined as an emergency alarm, otherwise it is a regular fault alarm; Step 4: Fault information alarm The alarm module receives the data processing results of the data processing module in real time, and executes corresponding alarm tasks according to different fault categories; S41: Sensor failure alarm The sensor alarm in the control center sounds an alarm, and the yellow light on the status indicator board of the corresponding fault area turns on, reminding the staff to perform sensor maintenance; S42: Non-sensor fault alarm For emergency alarms such as equipment / machine failure, personal safety, fire, etc., execute step E421; for abnormal data changes in the cable cabin, high-voltage box, and tow cable tension, execute step E422; E421: Emergency alarm Manually operate the emergency button, and check and handle faults; E422: General fault alarm (1) In case of cable cabin failure, the operation panel rotates to +45°, prompting fault handling. After the fault handling is completed, the operation panel rotates to -45°; (2) High-voltage box alarm High voltage is a dry contact input. When an alarm is generated, the dry contact closes to remind you to handle the fault. (3) If the towline tension fails, the fault information will be displayed and the fault will be handled; Step 5: Determine the system operation status If the system is powered off, proceed to step 6. If the system is in operation, repeat steps 2 to 4. Step 6: End.
