Description

Technical Field

[0001] This invention relates to the field of shipboard sewage monitoring technology, and in particular to a shipboard sewage storage and monitoring system. Background Technology

[0002] According to national regulations, domestic sewage generated by inland waterway vessels during navigation cannot be arbitrarily discharged into rivers and lakes; instead, a "storage on board, delivery on shore" treatment scheme should be adopted. However, the implementation of this scheme has encountered many problems in practical application.

[0003] First, shipboard sewage includes the excrement of crew members. When this excrement is discharged into a relatively enclosed space (sewage storage tank), it decomposes gradually in an oxygen-deficient environment, producing flammable gases such as methane. When the concentration of these flammable gases reaches a certain level, the complex electromagnetic environment of the ship's cabins may pose a significant safety risk to routine maintenance and repair activities of monitoring systems. It should be noted that when sewage storage tanks were previously "installed but not used," this safety risk was almost zero; however, with the gradual standardization of sewage storage tank use, this safety risk has increased daily.

[0004] Secondly, previous technical solutions (such as patent ZL202411528926.8) only provided early warning information for potential safety risks, without setting up real-time processing solutions for shipboard staff.

[0005] Finally, after the shipborne sewage monitoring system was put into use, it frequently lost its monitoring effectiveness due to power outages. The causes of power outages were partly due to accidental factors such as loose plugs, wiring faults, and prolonged periods of inactivity, but in many cases, they were due to malicious human intervention—that is, shipboard personnel attempting to evade monitoring by cutting off the power. Although a previous patent (ZL202411528926.8) proposed a solution of "equipping the shipborne monitoring system with a battery to simultaneously monitor the external power supply voltage, and using the battery for emergency power supply to send early warning signals after a significant drop in the external power supply voltage (i.e., a deliberate power outage)," this solution did not simultaneously consider the possibility of "communication signal interference leading to communication interruption." When a situation arises where "communication between the shipborne monitoring system and the internet cloud server module is interrupted for an extended period due to environmental or terrain reasons, during which the internet cloud server module cannot receive monitoring data and early warning signals, and after communication is restored, it is found that large sections of monitoring data from the period of communication interruption are missing," the above-mentioned solutions cannot distinguish whether the cause of the "large sections of missing monitoring data" is "a functional failure of the shipborne monitoring system during the communication interruption," "the shipborne monitoring system was manually powered off for an extended period during the communication interruption," or both of these situations exist simultaneously.

[0006] To address the aforementioned issues, this solution proposes a monitoring system for the storage of shipboard domestic sewage. Summary of the Invention

[0007] The purpose of this invention is to provide a monitoring system for the storage of domestic sewage on ships in order to solve the above-mentioned problems.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: A shipboard sewage storage and monitoring system includes: The integrated wastewater storage tank module is configured to monitor the wastewater level, pH value, and flammable gas concentration in the wastewater storage tank in real time through installed sensors. The monitoring data analysis and processing module is configured to analyze various types of information obtained by the sensors in real time and issue safety warnings based on the analysis results; The cockpit control panel module is configured to display various information obtained by sensors in real time, as well as safety warning information determined by the monitoring data analysis and processing module. It can also control the opening / closing of the dedicated exhaust system on the integrated sewage storage tank module through human-machine interaction. The communication module is configured to include a 4G / 5G communication module, a GPS navigation module, a Beidou navigation module, and a dedicated external antenna. It can periodically transmit various monitoring data obtained by the sensors on the integrated sewage storage tank module, safety warning information determined by the monitoring data analysis and processing module, and the ship's current geographic positioning data to the Internet cloud server module. The Internet cloud server module is configured to provide service alerts based on the analysis of various monitoring data.

[0009] Preferably, the specific method by which the monitoring data analysis and processing module analyzes data to determine a safety warning is as follows: If the methane volume ratio concentration detected by the flammable gas sensor is less than 5%, it is determined that no safety warning is required. If the methane volume ratio concentration detected by the combustible gas sensor is between 5% and 10%, and the pH value of the wastewater is less than 6.0 or greater than 8.0, it is determined to be a Level III safety warning. If the methane volume ratio concentration detected by the combustible gas sensor is between 5% and 10%, and the pH value of the wastewater is between 6.0 and 8.0, it is determined to be a level two safety warning; If the methane volume ratio concentration detected by the combustible gas sensor is greater than 10%, and the remaining space inside the tank calculated based on the volume of the integrated wastewater storage tank module and the height of the wastewater level is not less than... At that time, it was determined to be a Level 1 safety warning.

[0010] Preferably, after the monitoring data analysis and processing module analyzes the data to determine the safety warning level, it also prompts the safety warning information through the cockpit control panel module and implements risk elimination, specifically as follows: If it is a level 2 or level 3 safety warning, the safety warning information will be displayed through the cockpit control panel module, and after the user confirms the operation, the special exhaust system on the sewage storage tank will be opened to discharge the flammable gas from the sewage storage tank. If it is a Level 1 safety warning, after the safety warning information is displayed, the dedicated exhaust system will be turned on directly without user confirmation, and will automatically shut off after the concentration of flammable gas in the sewage storage tank drops to below 5%.

[0011] Preferably, the cockpit control panel module is also connected to the ship control system in the cockpit. When the number of safety warnings that occur within a first specified time period reaches a first specified value, the module automatically sends a control signal to the cabin ventilation system to start the cabin ventilation system.

[0012] Preferably, the cockpit control panel module is also connected to the Beidou short message communication equipment in the cockpit, or is equipped with a dedicated Beidou short message communication equipment. When the sensors on the integrated sewage storage tank module are working normally, but cannot transmit monitoring data to the Internet cloud server module in real time due to 4G / 5G signal interruption or strength below a preset threshold, the Beidou short message communication method can be used to send the ship's geographical location and 4G / 5G signal interruption status to the Internet cloud server module in real time. It can also be used when the sensors on the integrated sewage storage tank module malfunction or have no response signal due to power failure, the Beidou short message communication method can be used to send the ship's geographical location and monitoring equipment malfunction status to the Internet cloud server module in real time.

[0013] Preferably, during the 4G / 5G signal interruption, various safety warning information detected by the shipborne monitoring system is still transmitted to the Internet cloud server module in real time via BeiDou short message communication. However, the various monitoring data obtained by the sensors are not sent until the 4G / 5G signal is restored to normal and then sent to the Internet cloud server module via 4G / 5G mobile communication.

[0014] Preferably, the dedicated BeiDou short message communication device configured for the cockpit control panel module has a dedicated flat panel antenna mounted on the top of the cockpit and uses a battery pack inside the cockpit to power the cockpit control panel module and the BeiDou short message communication device.

[0015] Preferably, the specific method for the Internet cloud server module to analyze various monitoring data and issue service warnings is as follows: Analyze the monitoring data and BeiDou short message information of all ships. If the proportion of 4G / 5G signal interruption in a certain area is greater than 75%, issue an early warning for the 4G / 5G mobile communication service in the area. By analyzing the monitoring data of a single vessel and the BeiDou short message information, when the frequency of safety warnings of level two or above for a vessel reaches the second specified value within the second specified time period, a maintenance warning for the monitoring equipment of the sewage storage tank of the vessel is issued.

[0016] Preferably, the method further includes: By analyzing the monitoring data of a single vessel and the BeiDou short message information, when the frequency of no response signal from the monitoring equipment on the integrated sewage storage tank module reaches the third specified value during the normal navigation period of the vessel within the third specified time segment, a safety awareness service warning is issued to the vessel.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. This invention uses a combination of a level gauge, a pH meter, and a combustible gas sensor to analyze and assess safety risks in real time, and addresses risks promptly through the exhaust system on the sewage storage tank and the ventilation system in the ship's cabin, thereby improving the safety of the monitoring system during daily use and regular on-site maintenance.

[0018] 2. This invention connects the cockpit control panel module to the ship's control system within the cockpit, further integrating the monitoring system with the ship's control system. This not only ensures a stable power supply to the cockpit control panel module, essentially solving the problem of "malicious power outages interfering with the ship's monitoring system," but also allows the monitoring system to use the ship's own or additionally installed BeiDou short message communication equipment in emergency situations to promptly send status or warning information to the internet cloud server module via BeiDou short message communication, effectively improving the stability and effectiveness of the monitoring system's operation.

[0019] 3. This invention analyzes aggregated information through an internet cloud server module, enabling targeted assessment of regional communication service quality, monitoring of equipment maintenance needs, and assessment of the safety awareness of ship crew members. This provides reliable technical support for monitoring ship sewage within the entire inland waterway system. Attached Figure Description

[0023] Example 1

[0024] Its specific implementation method is combined with the appendix Figure 1 and attached Figure 2 Please provide a detailed explanation.

[0025] Appendix Figure 1 This invention provides a structural block diagram of a shipboard sewage storage and monitoring system, which shows the connection relationship between the integrated sewage storage tank module and the Internet cloud server module, and marks the main functional interaction flow of each module.

[0026] In this embodiment, it includes: Integrated wastewater storage tank module, monitoring data analysis and processing module, cockpit control panel module, communication module and Internet cloud server module; The integrated wastewater storage tank module is equipped with a variety of sensors that can monitor the wastewater level, pH value, and concentration of combustible gases in the wastewater storage tank in real time. The monitoring data analysis and processing module can analyze various types of information obtained by the sensors in real time and issue safety warnings based on the analysis results; The cockpit control panel module can display various information obtained by the sensors in real time, as well as safety warning information determined by the monitoring data analysis and processing module. It can also control the opening / closing of the dedicated exhaust system on the integrated sewage storage tank module through human-machine interaction. The communication module includes a 4G / 5G communication module, a GPS navigation module, a Beidou navigation module, and a dedicated external antenna. It can periodically transmit various monitoring data obtained by the sensors on the integrated sewage storage tank module, the safety warning information determined by the monitoring data analysis and processing module, and the ship's current geographic positioning data to the Internet cloud server module. The Internet cloud server module can provide service alerts based on the analysis of various monitoring data.

[0027] A level gauge installed on the integrated wastewater storage tank module is used to monitor the liquid level in real time, while a combustible gas sensor is used to monitor the concentration of methane, a combustible gas, in the wastewater storage tank. Available combustible gas sensors include infrared sensors, catalytic combustion sensors, and semiconductor sensors. Considering the cost-effectiveness for widespread application of shipboard wastewater monitoring systems, semiconductor sensors are the most suitable.

[0028] It should be noted that when sewage storage tanks were previously "installed but not used," the concentration of flammable gases inside was almost zero, and the corresponding safety risks were not a concern. This is the main reason why previous technical solutions for monitoring shipboard sewage did not mention the safety risks of flammable gases. However, with the gradual standardization of sewage storage tank use, such safety risks have increased significantly. Shipboard sewage includes feces, and when feces enter a relatively enclosed space (sewage storage tank), it gradually decomposes under the action of anaerobic microorganisms, producing gases such as methane, carbon dioxide, and hydrogen sulfide. Among these, methane is the main component, accounting for approximately 50% to 70% of the total volume of gases produced during decomposition.

[0029] Furthermore, the decomposition of feces into methane requires a slightly acidic to neutral environment (pH approximately 6.8–7.5). Normally, shipboard sewage meets this requirement. However, the introduction of toilet cleaners (some acidic, some alkaline) can significantly alter the pH of the sewage in the storage tank, causing it to become more acidic or alkaline, thus interrupting the methane production process. Therefore, a pH meter installed on the integrated sewage storage tank module to monitor the sewage pH can be used to indicate the methane production process. That is, when the sewage pH meets the slightly acidic to neutral environment for methane production, a sustained increase in methane concentration within the storage tank can be expected over a period of time. However, if the sewage pH deviates significantly from this environment, there is no need to worry about a continued increase in methane concentration.

[0030] It should be noted that sewage discharge points on ships (such as toilets) are connected to sewage storage tanks inside the hull via long pipes. Therefore, the sewage storage tanks are not completely sealed spaces; theoretically, flammable gases within the tanks could be slowly released into the atmosphere through the pipes. However, due to the length, relatively small diameter, and numerous bends in the sewage discharge pipes, the automatic emission efficiency of flammable gases from the storage tanks is normally very low. When the sewage pH level meets the requirements for methane production (a slightly acidic to neutral environment), the rate of methane production within the storage tank far exceeds the emission rate, causing the concentration to rise continuously. Therefore, when a pH meter installed on the integrated sewage storage tank module is used in conjunction with a flammable gas sensor, the safety risks posed by flammable gases can be effectively assessed.

[0031] The liquid level in the wastewater storage tank monitored by the level gauge, the methane concentration in the wastewater storage tank monitored by the combustible gas sensor, and the pH value of the wastewater in the wastewater storage tank monitored by the pH meter are all transmitted in real time to the monitoring data analysis and processing module. The monitoring data analysis and processing module analyzes this data in real time, assesses safety risks, and determines whether to issue a safety warning. The specific method is as follows: If the methane volume concentration detected by the combustible gas sensor is below 5%, no safety warning is required; if the methane volume concentration detected by the combustible gas sensor is between 5% and 10%, and the wastewater pH value is less than 6.0 or greater than 8.0, a Level III safety warning is issued; if the methane volume concentration detected by the combustible gas sensor is between 5% and 10%, and the wastewater pH value is between 6.0 and 8.0, a Level II safety warning is issued; if the methane volume concentration detected by the combustible gas sensor is greater than 10%, and the remaining space inside the tank calculated based on the integrated wastewater storage tank module volume and the wastewater level is not less than [a certain value], a Level II safety warning is issued. At that time, it was determined to be a Level 1 safety warning.

[0032] After the monitoring data analysis and processing module analyzes the data and determines the safety warning level, it will also display safety warning information through the cockpit control panel module and implement risk elimination, specifically as follows: If it is a Level 2 or Level 3 safety warning, the safety warning information will be displayed through the cockpit control panel module. After the user confirms the operation, the dedicated exhaust system on the sewage storage tank will be opened to expel the flammable gas from the sewage storage tank. The default opening time of the dedicated exhaust system is 5 minutes. If it is a Level 1 safety warning, after the safety warning information is displayed, the dedicated exhaust system will be opened directly without user confirmation. It will automatically shut off after the concentration of flammable gas in the sewage storage tank drops to below 5%.

[0033] It should be noted that wastewater storage tanks are mostly located in enclosed compartments on ships (usually below the main deck, at the bottom of the hull) used to house engines and for crew operation. However, the exhaust system on these tanks, limited by size and operating power, cannot directly vent flammable gases to the main deck via pipes. Instead, it uses small fans and exhaust vents to enhance gas exchange between the inside and outside of the tank, thus reducing the flammable gases inside. In other words, the flammable gases in the wastewater storage tank can only be discharged into the poorly ventilated engine room. From this perspective, even after the flammable gases are discharged from the wastewater storage tank, the safety risk still exists.

[0034] To effectively address the aforementioned safety risks, the cockpit control panel module is also connected to the ship's control system within the cockpit. When the condition that "the cumulative number of safety warnings within a first specified time period reaches a first specified value" is met, it can automatically send a control signal to the engine room ventilation system to activate the engine room ventilation system. The default activation time is 5 minutes. Preferably, the first specified time period is 24 hours, and the first specified value is 3.

[0035] It should be noted that, to prevent overheating damage during engine operation, dedicated ventilation systems are installed in the engine rooms of ships, and these systems are periodically activated during ship operation. Additionally, inland waterway vessels are mostly small to medium-sized cargo ships, and the sewage storage tanks installed on these vessels are typically [volume missing]. The engine compartment has a volume of approximately [missing information]. When the first designated time period is 24 hours and the first designated value is 3, according to the set condition of "the cumulative number of safety warnings within the first designated time period reaches the first designated value", it can be known that even if the gas (combustible gas accounting for 5%) discharged into the engine compartment reaches the limit value 3 times within 24 consecutive hours, it will still be considered safe. The concentration of flammable gases in the engine compartment reached a maximum of 0.5%, far below the lower explosive limit of 5% for methane. Therefore, the safety risks posed by flammable gases can be effectively controlled and managed by promptly activating the engine compartment's ventilation system. Furthermore, if the frequency of safety warnings is lower than the aforementioned standard, the regular activation of the dedicated ventilation system in the engine compartment during normal ship operation can effectively reduce the concentration of flammable gases and manage safety risks.

[0036] Under normal circumstances, shipboard monitoring systems transmit various monitored data to an internet cloud server module in real time via 4G / 5G communication. However, during navigation, ships often enter areas with weak 4G / 5G signals, leading to communication disruptions and the inability to upload monitored data in a timely manner. To address this, a previous technical solution (ZL202210900497.7) proposed that the shipboard monitoring system temporarily store monitoring data and upload it after the 4G / 5G signal is restored. However, this solution has a potential problem: if the shipboard monitoring system malfunctions, is interfered with by a power outage, or both during a 4G / 5G signal interruption, the temporarily stored monitoring data may be lost, and the system cannot identify the cause of the data loss. This not only reduces the effectiveness of the monitoring system but also hinders its continuous performance optimization through upgrades and maintenance. More importantly, the safety risks posed by flammable gases may be uncontrollably amplified in the event of data loss.

[0037] Therefore, compared with previous technical solutions (ZL202210900497.7 and patent ZL202411528926.8), this system has made three key adjustments.

[0038] First, a "cockpit control panel module" was installed in the ship's bridge and connected to the ship's control system within the bridge. This setup not only ensures that the engine compartment ventilation system can be automatically activated to mitigate the safety risk posed by flammable gases when the risk reaches a certain level, but also provides the "cockpit control panel module" with an independent and stable power supply, making it less susceptible to malicious power outages. It should be noted that the integrated wastewater storage tank module, monitoring data analysis and processing module, and the core components of the 4G / 5G communication and navigation modules (excluding the external antenna) are all located in the engine compartment and can only be powered through sockets within the compartment. This power supply method is easily affected by various factors, including malicious unplugging of the power cord.

[0039] Secondly, the "cockpit control panel module" is equipped with BeiDou short message communication equipment for emergency communications. This equipment can be used for both assessing the quality of 4G / 5G communication services and transmitting information in emergency situations. For example, when 4G / 5G communication is interrupted, the ship's geographical location and signal interruption status can be sent in real time to the internet cloud server module via BeiDou short message communication. This helps identify areas with poor 4G / 5G communication service quality, providing a reference for national communications authorities in optimizing regional communication service quality. Furthermore, if monitoring equipment malfunctions during a 4G / 5G communication interruption, the fault code can be promptly sent to the internet cloud server module to prevent information loss and facilitate subsequent system upgrades and maintenance. Additionally, various safety warnings detected by the shipborne monitoring system during a 4G / 5G communication interruption can also be promptly transmitted to the internet cloud server module for safety risk management. For example, during a 4G / 5G communication outage, if the sensors on the integrated sewage storage tank module do not malfunction (i.e., no fault code is submitted) but there is no response signal, it indicates that there has been a malicious power outage.

[0040] It should be noted that some inland waterway vessels are already equipped with BeiDou short message communication equipment. For these vessels, only functional connection between the cockpit control panel module and the BeiDou short message communication equipment is required. For inland waterway vessels that have not yet installed BeiDou short message communication equipment, a cost-effective consumer-grade shipborne terminal can be installed during the deployment of this system. The dedicated antenna of the shipborne terminal can be deployed near the top of the cockpit, which is beneficial for utilizing the power supply system in the cockpit (usually equipped with a dedicated battery pack, which is stable and reliable and can meet large instantaneous power requirements, such as the instantaneous power during short message transmission) and also facilitates the adjustment of the antenna orientation and position before short message transmission.

[0041] Finally, the "cockpit control panel module" is equipped with some control functions of the shipborne monitoring system. It can be used to provide real-time warnings about flammable gases to cockpit personnel, and also to control the BeiDou short message communication equipment to promptly transmit critical information such as power outages to the internet cloud server module when other components of the shipborne monitoring system in the engine room are maliciously powered off. It is important to emphasize that if other components of the shipborne monitoring system in the engine room (including the core part of the communication module) are maliciously powered off, 4G / 5G communication will be interrupted regardless of whether the 4G / 5G signal strength in that area meets communication requirements. In this case, the BeiDou short message communication method, which relies on the ship's control system for power supply, will become the only reliable communication method.

[0042] Of course, due to the limitations of the BeiDou short message communication system itself (such as high instantaneous power, limited message length, and additional service charges), non-critical information (such as various monitoring data obtained by sensors on the integrated sewage storage tank module) does not need to be transmitted through BeiDou short message communication. It can be sent to the Internet cloud server module after the 4G / 5G signal is restored to normal.

[0043] The three key adjustments mentioned above are specifically manifested in the following ways in application: The cockpit control panel module is also connected to the Beidou short message communication equipment in the cockpit, or is equipped with a dedicated Beidou short message communication equipment. When the sensors on the integrated sewage storage tank module are working normally, but cannot transmit monitoring data to the Internet cloud server module in real time due to 4G / 5G signal interruption or strength below the preset threshold, the Beidou short message communication method can be used to send the ship's geographical location and 4G / 5G signal interruption status to the Internet cloud server module in real time. It can also send the ship's geographical location and monitoring equipment failure status to the Internet cloud server module in real time when the sensors on the integrated sewage storage tank module malfunction or have no response signal due to power failure. During the 4G / 5G signal interruption, various safety warning information detected by the shipborne monitoring system is still transmitted to the Internet cloud server module in real time via Beidou short message communication. However, the monitoring data obtained by the sensors are not sent temporarily. They will be sent to the Internet cloud server module via 4G / 5G mobile communication after the 4G / 5G signal is restored to normal. The dedicated BeiDou short message communication equipment configured for the cockpit control panel module has a dedicated flat panel antenna mounted on the top of the cockpit and uses the battery pack in the cockpit to power the cockpit control panel module and the BeiDou short message communication equipment.

[0044] After a large amount of monitoring data from inland waterway vessels is transmitted to an internet cloud server module, the server will aggregate and analyze the information and issue service alerts and alarms. The specific method is as follows: By analyzing monitoring data from all ships and BeiDou short message information, if the proportion of 4G / 5G signal interruptions in a certain area exceeds 75%, an early warning will be issued for the 4G / 5G mobile communication service in that area. This early warning information is mainly provided to the national communications authorities to provide a reference for the continuous optimization of regional communication service quality.

[0045] Analyzing monitoring data and BeiDou short message information from a single vessel, when the frequency of Level II or higher safety warnings for that vessel reaches a second specified value within a second specified time period, a maintenance warning for the vessel's sewage storage tank monitoring equipment is issued. Preferably, the second specified time period is one week, and the second specified value is 5. It should be noted that such situations may arise because "there are many personnel on board, but the sewage storage tank has a small capacity, resulting in the failure to promptly discharge and clean up feces, producing a large amount of flammable gas," or because "long-term accumulation of incompletely removed dirt at the bottom of the sewage storage tank leads to the continuous emission of flammable gas even when the total amount of sewage in the tank is not large." Therefore, this warning information is primarily provided to maintenance personnel of the monitoring system to facilitate further understanding of the situation during actual onboard maintenance and to determine subsequent sewage storage tank replacement or deep cleaning work.

[0046] Analyzing monitoring data and BeiDou short message information from a single vessel, when the frequency of "no response signal from the monitoring equipment on the integrated sewage storage tank module during normal navigation" reaches a third specified value within a third specified time period, a safety awareness service warning is issued to the vessel. Preferably, the third specified time period is one month, and the third specified value is 5. It should be noted that "no response signal from the monitoring equipment on the integrated sewage storage tank module" signifies an abnormal power outage. During normal navigation, abnormal power outages of the monitoring equipment may lead to various safety risks. Therefore, this warning information is primarily provided to the vessel's management and the shipping company to urge them to remind the crew to enhance safety awareness and avoid various risks.
