Description

Technical Field

[0001] This utility model relates to the field of gas monitoring technology, and more specifically, to a marine hydrogen sulfide gas monitoring system. Background Technology

[0002] In fishing operations, the fish hold of fishing boats is usually a closed structure with only a small entrance for personnel to enter and exit, and for loading and unloading fish. To maintain the freshness of the fish in the hold, ice is commonly used for preservation. Since ice is added from top to bottom, fish at the bottom of the hold may not receive enough new ice, and the existing ice can easily melt and cause the fish to rot and spoil.

[0003] However, rotting fish in the fish hold of a fishing boat can release toxic hydrogen sulfide gas, which is an extremely dangerous gas. When working on board, crew members may need to enter the fish hold, and exposure to a certain concentration of hydrogen sulfide gas could pose a significant safety risk to them.

[0023] like Figure 1 As shown in the figure, an embodiment of the present invention provides a hydrogen sulfide gas monitoring system, including a hydrogen sulfide gas detection module, a central control module, and a monitoring platform. The hydrogen sulfide gas detection module is communicatively connected to the central control module, and the central control module is communicatively connected to the monitoring platform. The hydrogen sulfide gas detection module is located in the fish tank area. The hydrogen sulfide gas detection module is used to acquire hydrogen sulfide gas concentration information in the fish tank area and transmit the hydrogen sulfide gas concentration information to the central control module. The central control module is used to transmit the hydrogen sulfide gas concentration information to the monitoring platform.

[0024] Specifically, Figure 1The dashed line indicates the communication connection between the hydrogen sulfide gas detection module and the central control module, which in turn communicates with the monitoring platform. In the fishing industry, ice is used to maintain the freshness of fish in the hold. During long-term storage, because ice is mainly added from the top, fish at the bottom of the hold often don't receive enough fresh ice. This causes the existing ice to melt, leading to rotting and the release of toxic gases, primarily hydrogen sulfide. Therefore, the hydrogen sulfide gas detection module can be deployed near the bottom of the hold to monitor the concentration of hydrogen sulfide in real time and transmit the data to the central control module. The central control module can be wall-mounted in the fishing boat's wheelhouse for easy monitoring by crew members. This allows them to view gas concentration information and receive alarm signals promptly, enabling them to take swift action in emergencies to ensure the safety of all crew members. When the detected hydrogen sulfide concentration exceeds a preset safety threshold, the central control module triggers an alarm to alert the crew to the potential danger. Furthermore, alarm information can be sent to a remote monitoring platform so that shore-based management personnel can also be notified promptly. The monitoring platform not only displays real-time monitoring data but also stores historical records and supports remote control. Operators can set alarm thresholds and view hydrogen sulfide concentration trends over specific time periods through the monitoring platform interface. For example, if the monitoring platform receives an alarm message from the central control module indicating that the current hydrogen sulfide concentration has exceeded the safety limit, the system will automatically trigger an emergency response and notify relevant personnel to take measures.

[0025] In one embodiment, the hydrogen sulfide gas detection module can be configured to detect hydrogen sulfide gas concentrations in the range of 0-100 PPM and has an LCD display showing the real-time concentration value. Users can set high and low alarm points; the detection module will trigger an alarm when the detected gas concentration exceeds the preset alarm point. The detection module uses wireless communication technology to ensure the stability and reliability of data transmission in complex marine environments. The central control module can be configured to process data from the hydrogen sulfide gas detection module and transmit it to the monitoring platform. For example, if the user sets the safe limit for hydrogen sulfide concentration to 13 PPM, when the hydrogen sulfide gas detection module detects a concentration greater than 13 PPM, the gas concentration information obtained by the detection module is transmitted to the central control module installed in the bridge. The central control module will display a high concentration warning message on its display screen and provide further audio-visual alarms through a built-in buzzer and indicator lights. Simultaneously, the central control module will upload the alarm information to the marine hydrogen sulfide gas intelligent monitoring platform.

[0026] In this embodiment, by installing a hydrogen sulfide gas detection module in the fish hold area, real-time monitoring of gas concentration can be achieved, ensuring that any gas concentration exceeding the standard is detected immediately. When workers have already entered or are preparing to enter the fish hold, potential safety hazards can be identified in a timely manner, allowing for the implementation of protective measures such as fish hold ventilation and the wearing of protective equipment, thus reducing the risk of accidents. The hydrogen sulfide gas detection module transmits the collected gas concentration signal to the signal conversion module, enabling data interaction between the hydrogen sulfide gas detection module and the central control module, ensuring stable data transmission. The central control module installed on the fishing vessel can not only display alarm information locally but also upload data to a monitoring platform located on land, ensuring timely monitoring regardless of whether the vessel is in coastal or open ocean areas. The monitoring platform can quickly transmit alarm information to relevant management personnel through preset methods, ensuring they can take necessary countermeasures immediately, thereby effectively avoiding health risks and safety accidents caused by excessive hydrogen sulfide concentration. This ensures comprehensive coverage from on-site monitoring to remote early warning, greatly improving the response speed and management efficiency to potential hazards. This hydrogen sulfide gas monitoring system, through the coordinated operation of the hydrogen sulfide gas detection module, the central control module, and the monitoring platform, can effectively monitor the safety status of the fish hold environment, promptly detect and handle potential dangers, reduce the probability of accidents, and thus ensure the safety of the fish hold environment and the personnel on board.

[0027] Optionally, the marine hydrogen sulfide gas monitoring system further includes a signal conversion module; one end of the signal conversion module is communicatively connected to the hydrogen sulfide gas detection module, and the other end is electrically connected to the central control module. The signal conversion module is used to convert the hydrogen sulfide gas concentration information from a wireless signal into an electrical signal, and send the converted hydrogen sulfide gas concentration information to the central control module.

[0028] Specifically, the fish hold of a fishing boat is usually a fully enclosed structure with only a small entrance for personnel and fish to enter and exit. The interior of the fish hold is usually divided into multiple compartments for storing different types of fish. One end of the signal conversion module is connected to the hydrogen sulfide gas detection module via wireless communication technologies such as LoRA, receiving hydrogen sulfide concentration data sent by the hydrogen sulfide gas detection module. The other end is electrically connected to the central control module via RS485 or other interfaces, converting the wireless signal sent by the hydrogen sulfide gas detection module, which has high stability, high signal strength, and strong anti-interference ability, into a level signal that the central control module can receive.

[0029] In this optional embodiment, the signal conversion module is compatible with different communication protocols, ensuring that the hydrogen sulfide gas detection module can interact with the central control module, thus ensuring stable data transmission even in complex marine environments. The signal conversion module converts the hydrogen sulfide concentration signal sent by the hydrogen sulfide gas detection module into a format that the central control module can process, ensuring that the data from the hydrogen sulfide gas detection module can be correctly identified and processed by the central control module.

[0030] Optionally, the hydrogen sulfide gas detection module includes a first wireless unit and a hydrogen sulfide detection unit; the first wireless unit is electrically connected to the hydrogen sulfide detection unit, and the first wireless unit is used to convert the hydrogen sulfide gas concentration information detected by the hydrogen sulfide detection unit into the wireless signal.

[0031] Specifically, such as Figure 2 As shown, the hydrogen sulfide detection unit monitors the concentration of hydrogen sulfide in the environment in real time and transmits the detection results to the first wireless unit. The hydrogen sulfide detection unit has high sensitivity and fast response capabilities, ensuring timely alarm when the hydrogen sulfide concentration suddenly increases. The first wireless unit then transmits the data collected by the hydrogen sulfide detection unit to the signal conversion module. Fish tank environments are typically enclosed structures, and the structure of these enclosed spaces is relatively complex. The internal environment may obstruct wiring; for example, the presence of corrosive gases, high temperatures, and high pressures can damage cables, making construction difficult and costly. Therefore, a first wireless unit is used, which can be a LoRA wireless unit. LoRA wireless units use wireless communication, eliminating the need for communication cables in enclosed spaces, avoiding various problems associated with wiring, and reducing the risk of detection system failure due to cable faults. Furthermore, LoRA wireless units have low power consumption, strong anti-interference capabilities, and strong penetration capabilities, making them suitable for use in multi-compartment fish tank environments. For example, in the complex internal layout of fishing boats, LoRA wireless signals can penetrate obstacles such as metal panels, ensuring stable data transmission.

[0032] In this optional embodiment, the hydrogen sulfide detection unit monitors the hydrogen sulfide gas concentration in the fish hold in real time, enabling timely detection of excessive hydrogen sulfide gas concentrations and reducing the risk of accidents. The first wireless unit utilizes wireless transmission, simplifying the installation process, increasing flexibility, and solving the wiring challenges of traditional wired connections in complex environments. Furthermore, its strong anti-interference capability makes it suitable for the special working environment of fishing vessels. In practical applications, even under adverse weather conditions, the signal generated by the first wireless unit remains stable, ensuring accurate data transmission to the monitoring platform, thereby improving the overall system reliability and real-time performance.

[0033] Optionally, the marine hydrogen sulfide gas monitoring system further includes a main power supply; the hydrogen sulfide gas detection module further includes a first backup power supply; the main power supply and the first backup power supply are electrically connected, the main power supply is also used to supply power to the first backup power supply, and the main power supply or the first backup power supply is used to supply power to the first wireless unit and the hydrogen sulfide detection unit.

[0034] Specifically, the main power supply is the core power supply unit of the entire monitoring system, typically configured to adapt to the ship's DC 24V power environment. The main power supply not only provides stable power to the hydrogen sulfide gas detection module but also has voltage regulation and protection functions to prevent damage to the equipment from voltage fluctuations. In the event of a power outage on board, the hydrogen sulfide gas detection module is equipped with a first backup power supply (e.g., 3.6V). When the main power supply fails, the backup power supply can automatically take over the power supply task, ensuring the continuous operation of the hydrogen sulfide gas detection module. Even when providing emergency power when the main power supply is unavailable, the hydrogen sulfide gas detection module can continue to acquire hydrogen sulfide gas concentration information and transmit it to the central control module. For example, if the ship experiences a mechanical failure leading to a power outage, the backup power supply can ensure that the hydrogen sulfide gas detection module maintains operation for at least several hours until the problem is resolved or other emergency measures are taken. The first backup power supply is charged through the main power supply to ensure it remains fully charged when the main power supply is operating normally. When the main power supply is interrupted, the first backup power supply automatically switches to power the hydrogen sulfide gas detection module, ensuring the continuous operation of the system. The main power supply not only supplies power to the system equipment but also charges the backup power supply through a charging circuit.

[0035] In this optional embodiment, the hydrogen sulfide gas detection module is powered by both a main power supply and a backup power supply, significantly improving the reliability and stability of the entire hydrogen sulfide monitoring system. The system maintains continuous operation whether under normal navigation conditions or in the event of emergencies (such as power outages or severe weather). The backup power supply allows the system to continue monitoring and issuing necessary alerts, effectively preventing potential dangers and greatly enhancing crew safety. In the event of severe weather or power system failure, the backup power supply ensures the continuous operation of critical safety monitoring functions, preventing monitoring interruptions due to power problems and thus protecting crew safety. When the main power supply is operating normally, it can charge the backup power supply, ensuring it is always at full capacity. This prevents the backup power supply from being unable to provide power in emergencies due to insufficient power, thereby improving the reliability of the hydrogen sulfide monitoring system.

[0036] Optionally, the hydrogen sulfide gas detection module further includes a first interaction unit; the first backup power supply is electrically connected to the first interaction unit, and the first wireless unit is electrically connected to the hydrogen sulfide detection unit through the first interaction unit.

[0037] Specifically, the hydrogen sulfide gas detection module includes an interactive unit to visually display the current status and issue alarms to the user. The interactive unit can include a buzzer and indicator lights, providing immediate audiovisual feedback when abnormal hydrogen sulfide concentrations are detected. When the detected hydrogen sulfide concentration exceeds a preset safety threshold, the buzzer will sound an alarm. This audible alarm can attract the attention of personnel in noisy shipboard environments, ensuring timely action. The buzzer's volume can be adjusted according to ambient noise levels to ensure clear audibility under all conditions. The buzzer may have an adjustable volume function to adapt to different working environments; the indicator lights can use a multi-color design (e.g., green for normal operation, red for alarm) to allow users to quickly identify the equipment status.

[0038] In this optional embodiment, the first interaction unit enables users to quickly identify the current status of the device. Especially in emergency situations, the dual visual and auditory cues significantly improve user reaction speed. The first interaction module provides a user-friendly interface, allowing operators to easily obtain current gas concentration information and make necessary settings, enhancing ease of use and safety. The first interaction unit provides an intuitive operating interface; users can view the status of each detection module on the LCD screen, improving both user convenience and overall system safety.

[0039] Optionally, the first wireless unit is a LoRA wireless unit, and the signal conversion module is a LoRA to RS485 module.

[0040] Specifically, the signal conversion module is a LoRA to RS485 module. The first wireless unit in the hydrogen sulfide gas detection module is a LoRA wireless unit. The LoRA to RS485 module receives the hydrogen sulfide concentration signal sent by the hydrogen sulfide gas detection module through the LoRA wireless unit. The hydrogen sulfide gas detection module sends the detected hydrogen sulfide concentration data to the LoRA to RS485 module via LoRA wireless technology. After receiving these signals, the LoRA to RS485 module converts them into a format suitable for processing by the central control module, such as the RS485 serial communication protocol format, to enable effective data interaction with the central control module. RS485 has strong anti-interference capabilities and a long transmission distance, and can maintain stable data transmission in complex electromagnetic environments, ensuring the accuracy and reliability of the monitoring system.

[0041] In this optional embodiment, the LoRA to RS485 converter enhances the signal reception capability of the central control module. In complex marine environments with numerous metallic obstacles, LoRA technology, with its long-distance transmission and strong penetration capabilities, ensures effective data transmission even in situations with weak signals or multiple obstacles. The LoRA to RS485 converter transforms the hydrogen sulfide concentration signal transmitted by the gas detection module via the LoRA wireless module into a format suitable for processing by the central control module, ensuring that the data from the gas detection module can be correctly identified and processed by the central control module.

[0042] Optionally, the central control module includes a signal receiving unit and a data transmission unit. The hydrogen sulfide gas detection module is communicatively connected to the signal receiving unit, and the signal receiving unit is electrically connected to the data transmission unit. The central control module sends the hydrogen sulfide gas concentration information to the monitoring platform through the data transmission unit.

[0043] Specifically, the signal receiving unit receives the level signal from the signal conversion module, performs preliminary processing on the signal, and then transmits the processed data to the signal transmission unit. For example, after receiving the signal from the signal conversion module, the signal receiving unit analyzes the signal to obtain hydrogen sulfide concentration data, and then converts the data into a format suitable for wireless transmission before transmitting it to the signal transmission unit. The signal transmission unit receives the data processed by the signal receiving unit and uploads it to the monitoring platform. The signal transmission unit can employ a multi-mode communication strategy, allowing the system to select the most suitable communication method based on the actual situation. When the fishing vessel approaches port, the signal transmission unit can switch to a faster, lower-cost network; while on the high seas far from the mainland, it relies on global satellite communication to ensure that important information is not lost under any circumstances.

[0044] In this optional embodiment, the signal receiving unit can stably receive signals from the signal conversion module and convert them into a format that the data transmission unit can receive, ensuring accurate data transmission. The signal transmission unit enables the central control module to transmit data to the monitoring platform even when the fishing vessel enters a remote sea area with weak signals, improving the reliability and timeliness of data transmission and facilitating management personnel to monitor the situation on-site and make appropriate decisions.

[0045] Optionally, the data transmission unit includes a second wireless unit, a mobile communication unit, and a satellite communication unit.

[0046] Specifically, the second wireless unit supports multiple wireless communication protocols (such as Wi-Fi and Bluetooth) for short-range data transmission, such as data exchange between different devices inside the fishing vessel. When the central control module sends hydrogen sulfide concentration data to the monitoring platform, the Wi-Fi module enables fast and stable data transmission, ensuring real-time monitoring. The mobile communication unit mainly refers to modules supporting cellular network communication, such as 4G or 5G modules, for medium- to long-range data transmission, such as in near-shore areas. When the fishing vessel is operating close to the coastline, the central control module can quickly upload detected anomalies to the remote monitoring platform via the mobile communication unit, facilitating timely response from shore-based management personnel. The satellite communication unit is a satellite navigation system-based communication unit suitable for data transmission in open ocean areas, ensuring data connectivity is maintained even when no other communication methods are available. When the fishing vessel enters open ocean areas where 4G signal coverage is insufficient, the central control module can send hydrogen sulfide concentration data to the remote monitoring center via the satellite communication unit, ensuring uninterrupted communication even far from land.

[0047] In this optional embodiment, multiple communication methods enable the central control module to adapt to different maritime environments. When the fishing vessel enters a remote area with weak signal, the system automatically switches to satellite communication to ensure uninterrupted data transmission, improving the reliability and timeliness of data transmission, and facilitating managers to monitor the situation on-site and make appropriate decisions. Managers can view the hydrogen sulfide concentration on the fishing vessel in real time via mobile phone or computer, and take immediate action upon detecting any abnormalities, greatly improving response speed and management efficiency. The satellite communication unit not only transmits data but also provides precise location information, enabling the monitoring platform to understand not only the current gas concentration but also accurately pinpoint the fishing vessel's location, improving rescue efficiency. Selecting appropriate communication methods based on the actual needs of different sea areas avoids the problem of insufficient communication coverage caused by a single communication method.

[0048] Optionally, the marine hydrogen sulfide gas monitoring system further includes a main power supply; the central control module further includes a second backup power supply; the main power supply is also used to supply power to the second backup power supply, and the main power supply or the second backup power supply is used to supply power to the signal receiving unit.

[0049] Specifically, the main power supply not only powers the hydrogen sulfide gas detection module but also provides stable power to the central control module, featuring voltage regulation and protection functions to prevent damage from voltage fluctuations. The central control module is powered by a second backup power supply (e.g., 12V) and the main power supply. The second backup power supply provides emergency power when the main power supply is unavailable, ensuring that the central control module can continue processing data and sending information to the monitoring platform even under extreme conditions. The second backup power supply is charged by the main power supply, ensuring it remains fully charged when the main power supply is operating normally. This allows it to continue powering the central control module in the event of a main power supply failure, ensuring that system operation is not interrupted due to main power supply issues.

[0050] In this optional embodiment, powering the central control module with both a main power supply and a backup power supply significantly improves the reliability and stability of the entire hydrogen sulfide monitoring system, ensuring continuous operation even in the event of emergencies. The backup power supply allows the system to continue monitoring the hydrogen sulfide gas concentration in the fish hold and issue necessary alarms when the concentration exceeds the limit, effectively preventing potential dangers and greatly enhancing crew safety. In the event of severe weather or power system failure, the backup power supply ensures the continuous operation of critical safety monitoring functions, thereby protecting the lives of the crew. When the main power supply is operating normally, it can charge the backup power supply, ensuring it is always at full capacity. This prevents the backup power supply from being unable to provide power in emergencies due to insufficient power, thus improving the reliability of the hydrogen sulfide monitoring system.

[0051] Optionally, the marine hydrogen sulfide gas monitoring system further includes a wireless receiving unit; the second wireless unit communicates with the monitoring platform through the wireless receiving unit, and the mobile communication unit and the satellite communication unit communicate with the monitoring platform respectively.

[0052] Specifically, the wireless receiving unit receives data from the second wireless unit of the central control module and forwards this data to the monitoring platform. The second wireless unit establishes a connection with the wireless receiving unit via Wi-Fi protocol, thereby enabling data transmission with the monitoring platform. This is suitable for efficient data transmission over short distances, such as inside fishing vessels or in near-shore areas. The mobile communication unit establishes a connection with the monitoring platform via a 4G network, thereby enabling data transmission with the monitoring platform. This is suitable for medium- to long-distance data transmission, such as in near-shore areas. The satellite communication unit, based on a satellite navigation system, establishes a connection with the monitoring platform via satellites (such as BeiDou satellites), thereby enabling data transmission with the monitoring platform. This is suitable for data transmission in open ocean areas, ensuring data connectivity is maintained even when no other communication methods are available.

[0053] In this optional embodiment, the wireless receiving unit typically has stronger signal processing capabilities, enabling it to optimize the received data. By using a wireless receiving unit, the potential for signal instability caused by factors such as the vessel's location, weather conditions, and the marine environment during direct Wi-Fi data transmission is reduced. When fishing vessels are operating along the coast, they primarily rely on Wi-Fi or 4G wireless modules to maintain communication with the monitoring platform; when entering open ocean areas, they switch to satellite communication units to ensure uninterrupted data transmission, thus improving the system's reliability and usability.

[0054] Optionally, the central control module further includes a second interaction unit, which is electrically connected to the signal receiving unit.

[0055] Specifically, the central control module includes an interactive unit to visually display the current status to the user and issue alarms. A second interactive unit processes data from the signal receiving unit, ensuring that all received information is accurately and promptly transmitted to personnel. The interactive unit may include a buzzer and indicator lights, providing immediate audiovisual feedback when abnormal hydrogen sulfide concentrations are detected. When the detected hydrogen sulfide concentration exceeds a preset safety threshold, the buzzer sounds an alarm, which can attract the attention of personnel in the noisy cabin environment, ensuring they can take timely action.

[0056] In this optional embodiment, the second interactive module not only provides a user-friendly interface, greatly facilitating operators in obtaining real-time gas concentration information and performing necessary processing, thus improving ease of use and safety, but also displays the status of each detection module on an LCD screen through an intuitive interface, enabling staff to promptly detect anomalies. The marine hydrogen sulfide gas monitoring system can provide immediate alarm notifications through indicator lights and buzzers in the interactive unit, ensuring that any anomalies are quickly detected. The central control module's interactive unit not only optimizes the user experience, making monitoring and response measures simpler and more direct, but also enhances the overall safety of the system, ensuring rapid response in emergencies and effectively protecting the lives of crew members and the stable operation of the vessel.

[0057] Optionally, the hydrogen sulfide gas detection module includes an installation structure, which includes a magnetic suction plate for adhering to the inner wall of the fish tank area.

[0058] Specifically, the magnetic chuck can be made of high-strength neodymium iron boron or other permanent magnet materials, possessing strong magnetic force that allows it to firmly adhere to metal surfaces. The magnetic chuck can be directly attached to the bulkhead, ensuring the hydrogen sulfide gas detector is stably fixed and preventing it from loosening or falling off due to ship movement. Hydrogen sulfide gas tends to accumulate in low-lying areas, so the hydrogen sulfide gas detector can be installed near the bottom of the fish tank. By using the magnetic chuck, the detector's specific position can be flexibly adjusted according to actual needs to ensure optimal monitoring results. For example, in a large fish tank, four hydrogen sulfide gas detection modules can be installed at the four corners of the tank, each module fixed at an appropriate height using a magnetic chuck, ensuring comprehensive monitoring of the hydrogen sulfide concentration throughout the entire tank.

[0059] In this optional embodiment, the magnetic chuck simplifies the installation and removal process of the hydrogen sulfide gas detection module, reducing construction time and costs. No drilling or nailing is required; installation is completed simply by placing the hydrogen sulfide gas detection module in the appropriate position. During routine maintenance, workers can remove the hydrogen sulfide gas detection module for calibration or replacement and then quickly reinstall it, improving work efficiency. The magnetic chuck firmly adheres to metal surfaces, ensuring that the hydrogen sulfide gas detection module will not loosen or shift even during ship navigation, thus ensuring the accuracy of data acquisition and avoiding false alarms or missed alarms caused by the movement of the hydrogen sulfide gas detection module.

[0060] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
