Description

Technical Field

[0001] The present invention relates to the technical field of marine monitoring equipment, and in particular to a marine hydrogen sulfide gas monitoring system and a fishing boat. Background Art

[0002] Fish holds on fishing vessels are often fully enclosed, with only a small entrance for crew and cargo. To keep the fish fresh, ice is used. If the fish is stored in the hold for extended periods, since ice is added from the top down, the fish at the bottom have difficulty reaching the new ice. Once the ice melts, the fish at the bottom, lacking sufficient cooling, can begin to rot, producing toxic gases, primarily hydrogen sulfide. The fully enclosed design of the hold encourages the accumulation of these toxic gases, which gradually increase over time, posing a health risk to those on board.

[0003] In relevant technical solutions, fishing vessels often need to rely on the experience of the crew to judge whether there is toxic gas in the cabin, which poses a great threat to the health of the crew and also affects the environmental safety on board. Summary of the Invention

[0023] In response to the problems existing in the above-mentioned related technologies, this embodiment provides a marine hydrogen sulfide gas monitoring system and a fishing boat.

[0024] like Figure 1 As shown, an embodiment of the present invention provides a marine hydrogen sulfide gas monitoring system, including a gas detection module, a central control module and a monitoring cloud platform; The gas detection module is arranged in the closed cabin and is connected to the central control module by wireless communication. The gas detection module is used to obtain the concentration of hydrogen sulfide gas.

[0025] In one embodiment, the cabin can be considered a closed area, with only entrances and exits for fish and workers. Before unloading, the entrances and exits of the cabin are sealed to keep the fish warm and prevent the fish or ice from spilling out due to the boat's turbulence. In this scenario, it is difficult for the gas detection module to communicate with the central control module via wired communication. For a closed cabin, wired communication modification is difficult and may result in a poor seal. In addition, the water added to the cabin contains electrolytes, which can easily corrode the wiring and affect the life of the equipment. Wireless communication is used to connect the central control module to the gas detection modules in each closed cabin, allowing the hydrogen sulfide gas concentration obtained by the gas detection module to be directly transmitted to the central control module.

[0026] The central control module is arranged in the cockpit and is used to receive status information of the gas detection module, wherein the status information includes power information and location information.

[0027] In one embodiment, the central control module is installed in the cockpit. The cockpit is typically where crew members operate and monitor the ship's operating status. Placing the central control module in the cockpit facilitates direct access and management by the crew. In one embodiment, since the number of cabins is typically greater than one, the number of gas detection modules corresponds to the number of cabins; and the number of central control modules is typically one, meaning that all gas detection modules can be managed by a single central control module.

[0028] In one embodiment, due to the harsh cabin environment, the gas detection module and the central control module are powered by energy storage equipment based on wireless communication to reduce exposed wires. In order to cope with possible power depletion problems, the power information and location information are associated with the gas detection module and uploaded to the central control module so that the central control module can monitor the power of the gas detection module.

[0029] The central control module is further configured to obtain the hydrogen sulfide gas concentration from the gas detection module, and upload the hydrogen sulfide gas concentration and the status information to the monitoring cloud platform.

[0030] The central control module manages the hydrogen sulfide gas concentration in all fish holds on the current fishing vessel, providing notifications to onboard personnel. The monitoring cloud platform manages the hydrogen sulfide gas concentration in all fish holds of multiple fishing vessels, summarizing and providing notifications to shore personnel. In one embodiment, a monitoring cloud platform manages more than one central control module, meaning that the monitoring cloud platform can aggregate and store information sent from central control modules on multiple fishing vessels, providing visualization when needed.

[0031] For example, the fault record query function can obtain fault records according to user needs, including the device status, device type, time, device number, installation location, fault cause and other attributes of the faulty device.

[0032] The monitoring cloud platform is set up in the cloud and is used to display and store the hydrogen sulfide gas concentration and the status information. When the hydrogen sulfide gas concentration or the status information is abnormal, an alarm push notification is issued.

[0033] The content stored in the monitoring cloud platform includes attributes such as status, device type, start time, end time, and device number. Users can query based on the above attributes to obtain the corresponding device information, including device type, department type, device number, device status, reporting time, monitoring type, installation location, etc.

[0034] When the concentration of hydrogen sulfide gas is abnormal, the central control module corresponding to the abnormal information and the corresponding gas detection module under the central control module are associated and stored. Among them, the gas detection module and the fish hold correspond to each other, that is, the fish hold with abnormal hydrogen sulfide gas concentration, the central control module corresponding to the fish hold, and the fishing boat corresponding to the central control module are corresponded, and the time when the abnormality occurs is recorded according to the timestamp. The abnormal fish hold can be monitored through the monitoring cloud platform, and an alarm push notification can be issued. According to the preset push strategy, it is pushed to the target user to realize scientific monitoring of hydrogen sulfide gas.

[0035] In this embodiment, by setting the gas detection module in the closed fish hold and wirelessly connecting the gas detection module to the central control module, the difficulty of renovating the fish hold is reduced, and the problem of short equipment life that may occur in the high humidity and high corrosion environment of the fishing boat due to the wired connection is prevented; the central control module set in the cockpit is used to receive and summarize the power information and position information of the gas detection module, monitor the hydrogen sulfide gas concentration and power, and use it to prompt the personnel on board; the monitoring cloud platform is set in the cloud, and is used to summarize and store the hydrogen sulfide gas concentration information from the central control module, as well as the power information and position information of each corresponding gas detection module in the central control module. When the information is abnormal, an alarm push notification is issued to prompt the target user. Through the three-level summary monitoring of the gas detection module, the central control module, and the monitoring cloud platform, prompts can be given to the personnel on board, as well as to the target users, so that hydrogen sulfide gas can be monitored and alarms can be given in time.

[0036] Optionally, the gas detection module has a unique cabin number, and the cabin number corresponds to the location information of the gas detection module; The gas detection module detects the concentration of hydrogen sulfide gas at a first preset frequency, and uploads the hydrogen sulfide gas concentration and the cabin number to the central control module.

[0037] In one embodiment, each gas detection module is installed in a different cabin and assigned a unique cabin number corresponding to its location. After the gas detection module detects the hydrogen sulfide gas concentration, it uploads the gas concentration and cabin number to the central control module. Even in complex or changing environments, the specific location of the cabin with excessive hydrogen sulfide can be quickly and accurately located, allowing timely action to ensure environmental safety and personnel health. This also facilitates the maintenance and management of gas detection equipment at multiple locations, improving work efficiency and management levels.

[0038] Because the gas detection module and central control module are connected via wireless communication and have independent power supplies, they monitor hydrogen sulfide gas concentration at a first preset frequency to conserve power. If the hydrogen sulfide concentration exceeds a preset threshold, the concentration and cabin ID are uploaded to the central control module, which generates an alarm to alert onboard personnel.

[0039] Optionally, the central control module is further used to: estimating the battery charge of the gas detection module according to the preset communication protocol used by the gas detection module and the first preset frequency; When the power estimation result indicates that the power is less than a preset power threshold, a power alarm is generated.

[0040] The battery level of the gas detection module is evaluated based on the preset communication protocol and the first preset frequency used by the gas detection module. This considers the energy consumed during data transmission and reception, as well as the energy required to perform gas concentration detection tasks at the set period.

[0041] When the battery level assessment indicates the current battery level is below the set threshold, a battery warning is triggered. This alert mechanism is designed to promptly alert maintenance personnel to the battery status of the gas detection module so they can schedule appropriate charging or battery replacement without disrupting monitoring operations. This effectively avoids monitoring interruptions due to insufficient battery power, ensuring continuous monitoring of hydrogen sulfide gas concentrations, thereby maintaining environmental safety and personnel health. It also facilitates the management of multiple gas detection points and reduces maintenance costs.

[0042] In one embodiment, mapping relationships between the communication protocol and the battery power consumption rate, and between the frequency and the battery power consumption rate, are constructed. For example, when the communication protocol is Bluetooth, the battery power consumption rate is 10mW / h, and the frequency is once a day, the battery power consumption rate is 200mW / d. After determining the type of communication protocol and the first preset frequency, a power estimation result is obtained.

[0043] Optionally, the preset communication protocol includes at least one of a wireless network protocol, a long-distance wireless communication protocol, a narrowband Internet of Things protocol, a Bluetooth wireless communication protocol, and a ZigBee wireless communication protocol.

[0044] The type of preset communication protocol is determined according to actual needs. For example, when the data transmission rate requirement is high, the preset communication protocol is the wireless network protocol (Wi-Fi protocol); when the communication distance is short and the data transmission rate requirement is low, the preset communication protocol is the Zigbee wireless communication protocol (Zigbee protocol); when the penetration requirement is strong, the preset communication protocol is the narrowband Internet of Things protocol (NB-IoT).

[0045] Optionally, the central control module has a unique vessel number; The central control module is further configured to upload the cabin status information and the vessel number to the monitoring cloud platform at a second preset frequency when the hydrogen sulfide gas concentration is lower than a preset concentration threshold, and to immediately upload the cabin status information and the vessel number to the monitoring cloud platform when the hydrogen sulfide gas concentration is higher than the preset concentration threshold, wherein the cabin status information includes the cabin number and the hydrogen sulfide gas concentration.

[0046] In one embodiment, the central control module uploads the cabin status information and the ship number to the monitoring cloud platform. One monitoring cloud platform can establish connections with multiple central control modules and simultaneously obtain and store information from different central control modules.

[0047] At a set second preset frequency, the central control module uploads cabin status information, including the cabin number and hydrogen sulfide gas concentration, along with the vessel number, to the monitoring cloud platform. This enables the monitoring cloud platform to obtain real-time information on the operating status of each gas detection module within each vessel and the hydrogen sulfide gas concentration in the environment. Even if the vessels are located in different sea areas or regions, effective monitoring and management of the onboard environmental conditions can be achieved. In the event of an abnormal increase in hydrogen sulfide gas concentration or other emergency situation, the specific vessel and its cabin can be quickly located, and timely measures can be taken to ensure navigation safety and personnel health. At the same time, this setup also facilitates centralized management and maintenance of multiple vessels, improving overall operational efficiency.

[0048] In one embodiment, the second preset frequency is lower than or equal to the first preset frequency. When the hydrogen sulfide gas concentration is normal, information is uploaded at the second preset frequency. To ensure the timeliness of abnormal state uploads, when the hydrogen sulfide gas concentration collected by the central control module is abnormal, the abnormal information is immediately uploaded and an alarm push notification is issued.

[0049] Optionally, the central control module is also used to generate a gas alarm when the hydrogen sulfide gas concentration of the gas detection module is higher than a preset concentration threshold, and display the cabin number corresponding to the gas detection module until the hydrogen sulfide gas concentration is lower than the preset concentration threshold.

[0050] When the hydrogen sulfide gas concentration data received by the central control module exceeds the preset concentration threshold, a gas alarm is generated. The central control module displays the cabin number corresponding to the gas detection module, indicating the specific area where the abnormality occurred. The gas alarm persists until the hydrogen sulfide gas concentration detected by the central control module again falls below the preset concentration threshold. This method can quickly locate the source of the problem when a dangerous gas leak occurs and continue to issue warnings until the environment returns to a safe level, effectively ensuring personnel safety and environmental protection. In addition, real-time monitoring and early warning mechanisms help to take timely measures to address potential risks and prevent the occurrence or escalation of accidents.

[0051] Optionally, when the hydrogen sulfide gas concentration or the status information is abnormal, issuing an alarm push notification includes: When the received hydrogen sulfide gas concentration is higher than a preset concentration threshold, or when the status information is abnormal, the corresponding ship number and the cabin number are sent to a preset target user.

[0052] When hydrogen sulfide gas concentration exceeds a preset threshold or status information shows an anomaly, an alarm push notification is triggered. The central control module then sends the corresponding vessel and cabin numbers to pre-defined recipients. When environmental conditions deviate from normal ranges or equipment operating status is detected as abnormal, relevant personnel are promptly notified of the specific vessel and cabin experiencing the problem. This accelerates response time and allows for effective action to address the anomaly, protecting personnel safety and maintaining normal facility operations.

[0053] Optionally, the central control module includes a communication unit, and the communication unit includes a mobile communication module and a satellite communication module; The monitoring cloud platform and the central control module are communicatively connected via the mobile communication module. When the signal strength of the mobile communication module is lower than a preset signal strength threshold, the central control module is communicatively connected to the monitoring cloud platform via the satellite communication module.

[0054] The central control module includes a communication unit that integrates a mobile communication module and a satellite communication module. The monitoring cloud platform and the central control module are connected via the mobile communication module.

[0055] When it is detected that the signal strength of the mobile communication module is lower than the preset signal strength threshold, the central control module automatically switches to communicating with the monitoring cloud platform through the satellite communication module. This method is conducive to maintaining effective communication with the monitoring cloud platform even when the mobile communication signal is poor, ensuring the continuity and reliability of data transmission. In addition, this dual communication mechanism is particularly suitable for environments with insufficient mobile communication coverage, such as at sea or in remote areas, providing stable support for real-time monitoring and management. In other words, no matter what the environment, communication can be maintained smoothly, which is conducive to timely response to various situations. For example, the mobile communication module includes at least one of a 4G module or a 5G module, and the satellite communication module includes at least one of a GPS and a Beidou communication module.

[0056] Optionally, the displaying and storing the hydrogen sulfide gas concentration and the status information includes: The hydrogen sulfide gas concentration and the status information are associated and stored via a relational database.

[0057] When displaying and storing hydrogen sulfide gas concentration and status information, data is stored in a relational database. Specifically, each detected hydrogen sulfide gas concentration is recorded in the database along with the corresponding status information for subsequent query and analysis.

[0058] This approach facilitates the integration and management of data from various monitoring points, allowing for rapid retrieval of gas concentration and status information under specific conditions. Furthermore, leveraging the structured nature of relational databases allows for flexible data processing and report generation, supporting decision-making. In other words, this storage approach not only improves data management efficiency but also enhances understanding and response capabilities for environmental conditions.

[0059] A fishing boat provided by an embodiment of the present invention includes the gas detection module and the central control module as described above.

[0060] The beneficial effects of the fishing boat compared to the existing technology are consistent with the ship-based hydrogen sulfide gas monitoring system, and will not be repeated here.

[0061] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the protection scope of the present invention.
