Description

Technical Field

[0001] The present invention relates to the technical field of marine hydrological monitoring, and specifically to an online monitoring system and method based on marine hydrological monitoring services. Background Art

[0002] Currently, in order to understand marine hydrological information, buoys, floating ships, etc. are usually set up at sea to obtain marine hydrological information and send it to the monitoring platform, and then the above hydrological data is statistically analyzed to form data such as marine hydrological maps. However, currently, due to the large coverage area of the ocean, especially the ocean waters utilized, a large number of marine buoys need to be set up. On the one hand, this is costly, and it is not conducive to the collection and analysis of data. In the prior art, there are also detection devices and management systems for hydrological water quality.

[0003] For example, Patent CN 104802936A discloses an offshore environmental monitoring buoy and system, including: a monitoring center and an offshore environmental monitoring buoy. The monitoring center communicates with the offshore environmental monitoring buoy through a wireless network. The offshore environmental monitoring buoy transmits marine water quality parameters to the monitoring center through the wireless network and receives instructions sent by the monitoring center. The monitoring center also includes a feedback module for sending feedback to the offshore environmental monitoring buoy to confirm receipt of the marine water quality parameters when receiving the marine water quality parameters sent by the offshore environmental monitoring buoy. The monitoring center is also used to send an instruction to set a preset water depth to the buoy and send the instruction to the buoy through the wireless network. The monitoring center can also be used to estimate the marine water quality parameters in the sea area near the buoy based on the marine water quality parameters sent by the buoy. It uses multiple buoys deployed in different sea areas to collect water quality parameters at various water depths, providing three-dimensional data support and theoretical basis for studying the variation law of marine water quality.

[0004] Patent CN109716382A discloses an online adaptive computing offloading method and system for marine tasks, which can obtain environmental information and user information in real time, establish an accurate model to describe the current system, and then achieve efficient task allocation to ensure latency. This solution is based on reinforcement learning, provides the current decision by learning from historical allocation strategies without future information, constructs an offloading model and optimizes it in real time to achieve efficient offloading of device tasks. It can not only make full use of energy, but also effectively reduce task latency and ensure QoS.

[0005] Patent CN11656781A discloses a remotely controllable undersea observation system with heterogeneous communication cascading and its data transmission method; the system includes distributed monitoring nodes, AUV mobile monitoring nodes, a relay transmission module, and a shore-based receiving system. The relay transmission module includes a bottom base station, a buoyancy self-balancing adjustment intermediate base station, and a dual-star backup controllable bidirectional communication base station that are sequentially connected by a zero-buoyancy coaxial cable from bottom to top. The relay transmission module has two working modes, namely the undersea communication mode and the sea surface communication mode. In the undersea communication mode, the dual-star backup controllable bidirectional communication base station dives to a specified depth below the sea surface. In the sea surface communication mode, the dual-star backup controllable bidirectional communication base station floats to the sea surface. It realizes cross-media communication between the sea and the air through multiple cascaded links, and remotely controls the working parameters of the distributed monitoring nodes and the mobile monitoring AUV.

[0006] Patent CN221757684U discloses an arrangement structure of a marine hydrological acquisition platform, which relates to the technical field of marine hydrological acquisition platforms and includes a marine floating buoy. An anchor is connected to the lower side of the marine floating buoy. A collection platform is provided on one side of the marine floating buoy. A fixed bracket is provided on the lower side of the collection platform. An anchor system heavy object is provided on the lower side of the fixed bracket. The marine floating buoy and the anchor are connected by an anchor rope. The technical solution provided by the present invention can collect data of basic hydrological elements such as water depth, tide level, flow velocity, flow direction, suspended sediment concentration, temperature, salinity, wind speed and wind direction. Especially for the data of suspended sediment concentration, temperature, and salinity, this platform can collect data at different depths according to requirements, while the existing data acquisition platforms can only collect part of the data or cannot collect it.

[0007] It can be seen that currently, in the monitoring and management of marine hydrological monitoring services, especially in terms of the composition and working methods of monitoring systems, the following defects still exist:

[0008] 1. In the prior art, the detection of marine hydrological information is to separately use marine hydrological data sensing devices to obtain marine hydrological data, and then the marine hydrological data is usually transmitted and received through a communication system, usually using a wireless communication system. Since the marine hydrological monitoring system is usually fixedly set and cannot move, the marine hydrological monitoring is not accurate and comprehensive enough. And for a mobile marine hydrological acquisition system, because this system usually uses self-propelled movement, the cost is high, and usually the navigation route cannot be planned. And in order to obtain sufficient detection accuracy, if fixed detection buoys are arranged, more fixed detection buoys need to be set, which increases the installation cost.

[0009] 2. In the prior art, in marine hydrological monitoring, fixed marine buoys are on the water surface. However, when encountering abnormal sea conditions, it is easy for the marine buoys to be damaged by the impact of waves, which will increase the cost of marine hydrological monitoring and it is not easy to notify when the buoy should float up in time, thus easily resulting in the lack of monitoring of marine hydrological data.

[0010] In this application, the wind and wave risk assessment system evaluates whether it will damage the fixed buoy hydrological monitoring system based on the marine hydrological information. By the mooring cable winding mechanism to wind the cable, the fixed buoy hydrological monitoring system is sunk to a certain depth underwater, and the underwater vehicle can navigate to the fixed buoy hydrological monitoring system so that the underwater vehicle and the fixed buoy hydrological monitoring system establish a wireless communication connection. After information exchange, the underwater vehicle then exchanges information with other fixed buoy hydrological monitoring systems on the water surface, so that underwater, the fixed buoy hydrological monitoring system underwater can communicate with the dynamic monitoring system data, in order to transfer the marine hydrological information collected by the fixed buoy hydrological monitoring system to the dynamic monitoring system through the underwater vehicle.

[0011] Facing the above technical problems, people hope to provide a safe, low-cost and efficient marine monitoring system to solve the above technical problems. Summary of the Invention

[0012] Aiming at the above technical problems, the purpose of the present invention is to provide an online method and system based on marine hydrological monitoring services to solve the problems raised in the above background technology.

[0013] To achieve the above purpose, the present invention provides the following technical solutions:

[0014] An online monitoring system based on marine hydrological monitoring services, including an online monitoring system, a fixed buoy hydrological monitoring system, and a mobile hydrological monitoring system; the online monitoring system is respectively communicatively connected with multiple fixed buoy hydrological monitoring systems and multiple mobile hydrological monitoring systems through satellite communication modules and communication satellites;

[0015] Among them, the online monitoring system includes a dynamic monitoring system, a data analysis module, a control module, and an early warning alarm module; multiple fixed buoy hydrological monitoring systems are evenly distributed in the sea areas of different location areas, including hydrological buoys, which are fixedly moored to the seabed through a mooring system. A hydrological monitoring module A, a satellite communication module A, and a wireless communication module A are arranged on the hydrological buoy. Multiple mobile hydrological monitoring systems include self-navigable floating boats and underwater vehicles; a hydrological monitoring module B, a satellite communication module B, and a wireless communication module B are arranged on the self-navigable floating boat, and a hydrological monitoring module C, a satellite communication module C, and a wireless communication module C are arranged on the underwater vehicle;

[0016] Among them, the hydrological monitoring modules A-C are used to obtain marine hydrological information, and the satellite communication modules A-C are used to communicate with the online monitoring system through communication satellites, so as to send the obtained marine hydrological information to the online monitoring system, and receive the operation instructions sent by the online monitoring system, so as to control the fixed buoy hydrological monitoring system to sink to the seabed when the wind and waves exceed its bearing capacity, and control the mobile hydrological monitoring system to sail to the area where hydrological monitoring is required to collect hydrological data;

[0017] At the same time, the wireless communication modules A-C are used for communication between the fixed buoy hydrological monitoring system and the mobile hydrological monitoring system; the dynamic monitoring system is used for online display of the obtained marine hydrological information, and the operation module is used to send operation instructions to operate the fixed buoy hydrological monitoring system and the mobile hydrological monitoring system; the data analysis module analyzes the obtained marine hydrological data, and when the marine hydrological information is monitored to be abnormal, an alarm is given through the warning alarm module.

[0018] Preferably, a wind power generation system and a wave power generation system are provided on the fixed buoy hydrological monitoring system and the self-navigable floating ship; thus, the wind power generation system is used to obtain wind power, and the wave power generation system obtains wave energy to generate electric energy, so as to supply the electric energy to the fixed buoy hydrological monitoring system and the self-navigable floating ship.

[0019] Preferably, the fixed buoy hydrological monitoring system, the self-navigable floating ship and the underwater vehicle are all provided with detachable battery packs, and the connection is realized by using a detachable structure. The health status data of the detachable battery pack is sent to the dynamic monitoring system, so that the dynamic monitoring system monitors the health status of the detachable battery pack. When the health status of the detachable battery pack of the self-navigable floating ship or the underwater vehicle is abnormal, the operation module sends a control instruction to control the self-navigable floating ship or the underwater vehicle to return to the battery pack replacement station to replace the battery; when the health status of the detachable battery pack of the fixed buoy hydrological monitoring system is abnormal, control the self-navigable floating ship to transport a new detachable battery pack to the fixed buoy hydrological monitoring system and automatically replace the abnormal detachable battery pack.

[0020] Preferably, the data sub-module analyzes the collected marine hydrological data. When it is found through analysis that the degree of change in the marine hydrological data in a certain area exceeds a certain value or more accurate marine hydrological data of a certain area is required, the manipulation module sends a control instruction to control the self-navigable floating ship or underwater vehicle to return to the corresponding area, replace the corresponding fixed buoy hydrological monitoring system, or add observation points in the certain area to obtain marine hydrological information of more observation points.

[0021] Preferably, the fixed buoy hydrological monitoring system includes a mooring cable winding mechanism and a wind and wave risk assessment module. The wind and wave risk assessment module evaluates whether the fixed buoy hydrological monitoring system will be damaged based on the marine hydrological information. If so, the mooring cable winding mechanism winds the cable, causing the fixed buoy hydrological monitoring system to sink to a certain depth underwater, preventing damage to the fixed buoy hydrological monitoring system. When it sinks to a certain depth, the underwater vehicle can navigate to the fixed buoy hydrological monitoring system, establish a wireless communication connection between the underwater vehicle and the fixed buoy hydrological monitoring system, and after information exchange, the underwater vehicle exchanges information with other fixed buoy hydrological monitoring systems on the water surface, so that the fixed buoy hydrological monitoring system underwater can communicate with the dynamic monitoring system through the underwater vehicle, so as to transfer the marine hydrological information collected by the fixed buoy hydrological monitoring system to the dynamic monitoring system through the underwater vehicle and send the control instruction of the dynamic monitoring system to the fixed buoy hydrological monitoring system.

[0022] Preferably, the dynamic monitoring system also obtains the meteorological information and sends it to the data analysis module. The data analysis module conducts data analysis, identifies areas where the fixed buoy hydrological monitoring system and the mobile hydrological monitoring system cannot be deployed on the water surface, sinks the fixed buoy hydrological monitoring system in the area underwater, and drives away the mobile hydrological monitoring system.

[0023] Preferably, when deploying the fixed buoy hydrological monitoring system, first based on the meteorological and hydrological data, the data analysis module conducts analysis to obtain areas with large and complex changes in meteorological and hydrological data, and then generates a deployment map and a geographical location map of the fixed buoy hydrological monitoring system in the detection area, and sends them to the dynamic monitoring system for deploying the fixed buoy hydrological monitoring system based on the visual deployment map.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. In this application, the detection of ocean hydrology adopts a combination of fixed ocean hydrology observation buoys and mobile detection systems. Based on the relevant conditions of this sea area, the fixed ocean hydrology observation buoys are reasonably arranged instead of evenly arranged, so as to reduce the number of deployed fixed ocean hydrology observation buoys under the condition of obtaining the same monitoring hydrological accuracy. At the same time, for areas where it is not suitable to deploy fixed ocean hydrology observation buoys, supplementary detection is carried out based on the mobile ocean hydrology monitoring system, which not only saves costs but also provides sufficient detection density, thus having substantial practical value.

[0026] 2. In this application, the wind and wave risk assessment system evaluates whether it will damage the fixed buoy hydrology monitoring system based on the ocean hydrology information. The mooring cable retracting mechanism retracts the cable, causing the fixed buoy hydrology monitoring system to sink to a certain depth underwater. And the underwater vehicle can navigate to the fixed buoy hydrology monitoring system so that the underwater vehicle and the fixed buoy hydrology monitoring system establish a wireless communication connection. After information exchange, the underwater vehicle then exchanges information with other fixed buoy hydrology monitoring systems on the water surface, so that the fixed buoy hydrology monitoring system underwater can communicate with the dynamic monitoring system data underwater, so as to transfer the ocean hydrology information collected by the fixed buoy hydrology monitoring system to the dynamic monitoring system through the underwater vehicle.

[0036] Among them, the hydrological monitoring modules A-C are used to obtain ocean hydrological information, and the satellite communication modules A-C are used to communicate with the online monitoring system 1 through a communication satellite, so as to send the obtained ocean hydrological information to the online monitoring system 1, and receive the control instructions sent by the online monitoring system 1, so as to control the fixed buoy hydrological monitoring system 2 to sink to the seabed when the wind and waves exceed its bearing capacity, and control the mobile hydrological monitoring system 3 to sail to the area where hydrological monitoring is required for hydrological data collection.

[0037] At the same time, the wireless communication modules A-C are used for communication between the fixed buoy hydrological monitoring system 2 and the mobile hydrological monitoring system 3; the dynamic monitoring system 4 is used for online display of the obtained ocean hydrological information, the control module 6 is used to send control instructions to control the fixed buoy hydrological monitoring system 2 and the mobile hydrological monitoring system 3; the data analysis module 7 analyzes the obtained ocean hydrological data, and when the monitored ocean hydrological information is abnormal, an alarm is given through the early warning alarm module 6.

[0038] Preferably, a wind power generation system 2 and a wave power generation system 8 are provided on the fixed buoy hydrological monitoring system 2 and the self-navigable floating ship 11; thus, the wind power generation system 2 is used to obtain wind power, and the wave power generation system 8 obtains wave energy to generate electric energy, so as to supply the electric energy to the fixed buoy hydrological monitoring system 2 and the self-navigable floating ship 11.

[0039] Preferably, a detachable battery pack is provided on each of the fixed buoy hydrological monitoring system 2, the self-navigable floating ship 11 and the underwater vehicle 12, and the connection is realized by a detachable structure. The health status data of the detachable battery pack is sent to the dynamic monitoring system 4, so that the dynamic monitoring system 4 monitors the health status of the detachable battery pack. When the health status of the detachable battery pack of the self-navigable floating ship 11 or the underwater vehicle 12 is abnormal, the control module 6 sends a control instruction to control the self-navigable floating ship 11 or the underwater vehicle 12 to return to the battery pack replacement station 19 to replace the battery; when the health status of the detachable battery pack of the fixed buoy hydrological monitoring system 2 is abnormal, the self-navigable floating ship 11 is controlled to transport a new detachable battery pack to the fixed buoy hydrological monitoring system 2 and automatically replace the abnormal detachable battery pack.

[0041] Preferably, the fixed buoy hydrological monitoring system 2 includes a mooring cable winding mechanism and a wind and wave risk assessment module. The wind and wave risk assessment module assesses whether the fixed buoy hydrological monitoring system 2 will be damaged based on the marine hydrological information. If so, the mooring cable winding mechanism winds the cable, causing the fixed buoy hydrological monitoring system 2 to sink to a certain depth underwater, preventing damage to the fixed buoy hydrological monitoring system 2. When it sinks to a certain depth, the underwater vehicle 12 can navigate to the fixed buoy hydrological monitoring system 2, enabling the underwater vehicle 12 and the fixed buoy hydrological monitoring system 2 to establish a wireless communication connection. After information exchange, the underwater vehicle 12 exchanges information with other fixed buoy hydrological monitoring systems on the water surface, so that the fixed buoy hydrological monitoring system 2 underwater can communicate with the dynamic monitoring system 4 data-wise, enabling the underwater vehicle 12 to transfer the marine hydrological information collected by the fixed buoy hydrological monitoring system 2 to the dynamic monitoring system 4 and send the control instructions of the dynamic monitoring system 4 to the fixed buoy hydrological monitoring system 2.

[0043] Preferably, when deploying the fixed buoy hydrological monitoring system 2, first, based on the meteorological and hydrological data, the data analysis module 5 analyzes to obtain areas with large and complex changes in meteorological and hydrological data, and then generates a deployment map and a geographical location map of the fixed buoy hydrological monitoring system 2 in the detection area, and sends them to the dynamic monitoring system 4, so as to deploy the fixed buoy hydrological monitoring system 2 based on the visual deployment map.

[0044] Preferably, the underwater vehicle 12 is a thermally driven underwater vehicle. The data analysis module 5 calculates the temperature difference between the fixed buoy hydrological monitoring systems 2 based on the temperatures monitored by each fixed buoy hydrological monitoring system 2, and then generates the navigation path of the corresponding underwater vehicle 12 to make the best use of the temperature difference energy and reduce the use of the underwater vehicle 12's own energy. Specific Embodiment 2:

[0046] An online method based on marine hydrological monitoring services includes the following usage steps:

[0047] Step S1, when deploying the fixed buoy hydrological monitoring system 2, first evenly divide the area where hydrological monitoring is required into grids of equal density, and at the same time obtain the meteorological and hydrological data of this area. The data analysis module 5 analyzes based on the meteorological and hydrological data to form meteorological and hydrological contour lines, and based on the meteorological and hydrological contour lines, use the following formula to calculate the number of hydrological contour lines within a single grid:

[0048]

[0049] where N represents the number of hydrological contour lines, ΔH represents the contour interval of the meteorological and hydrological contour lines, n represents the number of elevation points within a single grid, i represents the i-th elevation point within a single grid, and G i represents the elevation value of the i-th elevation point within a single grid.

[0050] When the number of contour lines exceeds a certain value, the hydrological changes in the area where the grid is located are intense, and it is an area with large and complex meteorological and hydrological data changes. Otherwise, it is an ordinary area, forming different grade areas, and deploying different numbers of the fixed buoy hydrological monitoring system 2 based on different grade areas. The data analysis module 5 generates a deployment map and a geographical location map of the fixed buoy hydrological monitoring system 2 in the detection area based on the above analysis, and sends them to the dynamic monitoring system 4, so as to deploy the fixed buoy hydrological monitoring system 2 based on the visual deployment map and geographical location map;

[0051] Step S2, distribute multiple fixed buoy hydrological monitoring systems 2 in the sea areas of different location areas, including hydrological buoys, which are fixedly moored to the seabed through a mooring system, and use the following formula to calculate the sinking tension of the mooring system:

[0052]

[0053] where Z represents the sinking tension, W b represents the weight of the hydrological buoy, M h represents the density of seawater, T b represents the volume of the hydrological buoy, g represents the acceleration due to gravity, θ z represents the drag coefficient, S h represents the sea current velocity.

[0054] The hydrological monitoring modules A - C are used to obtain marine hydrological information. The satellite communication modules A - C are used to communicate with the online monitoring system 1 through communication satellites, so as to send the obtained marine hydrological information to the online monitoring system 1, and receive the manipulation instructions sent by the online monitoring system 1, and control the fixed buoy hydrological monitoring system 2 to sink to the seabed when the wind and waves exceed its bearing capacity according to the sinking tension, and control the mobile hydrological monitoring system 3 to sail to the area where hydrological monitoring is required to collect hydrological data;

[0055] Step S3, the wireless communication modules A - C are used to calculate the communication range of the wireless communication modules A - C, where the communication range includes:

[0056]

[0057] where R represents the communication range, F w represents the transmission power of the wireless communication modules A - C, Q F represents the transmitting antenna gain of the wireless communication modules A - C, Q J represents the receiving antenna gain of the wireless communication modules A - C, B represents the signal wavelength, π represents the pi, J w represents the received power threshold.

[0058] Based on the communication range, ensure effective communication between the fixed buoy hydrological monitoring system 2 and the mobile hydrological monitoring system 3; the dynamic monitoring system 4 is used to display the obtained marine hydrological information online, and the manipulation module 6 is used to send manipulation instructions to manipulate the fixed buoy hydrological monitoring system 2 and the mobile hydrological monitoring system 3;

[0059] Step S4, the dynamic monitoring system 4 obtains the health status data of the detachable battery pack, so that the dynamic monitoring system 4 monitors the health status of the detachable battery pack. When the health status of the detachable battery pack of the self - propelled floating ship 11 or the underwater vehicle 12 is abnormal, the manipulation module 6 sends a control instruction to control the self - propelled floating ship 11 or the underwater vehicle 12 to return to the battery pack replacement station 19 to replace the battery; when the health status of the detachable battery pack of the fixed buoy hydrological monitoring system 2 is abnormal, control the self - propelled floating ship 11 to transport a new detachable battery pack to the fixed buoy hydrological monitoring system 2 and automatically replace the abnormal detachable battery pack;

[0060] Step S5, the wind and wave risk assessment module assesses whether the fixed buoy hydrological monitoring system 2 will be damaged based on the marine hydrological information, and calculates the wind and wave impact force received by the hydrological buoy using the following formula:

[0061]

[0062] Among them, C F represents the impact force of wind and waves, M h represents the density of seawater, μ z wind and wave resistance coefficient, A b represents the cross-sectional area of the hydrological buoy under force, V F represents the wind and wave speed.

[0063] If the impact force of wind and waves is greater than the preset threshold value of the impact force of wind and waves, the mooring cable winding mechanism winds the cable, so that the fixed buoy hydrological monitoring system 2 sinks to a certain depth underwater, and damage to the fixed buoy hydrological monitoring system 2 will not be caused. When sinking to a certain depth, the underwater vehicle 12 can navigate to the fixed buoy hydrological monitoring system 2, so that the underwater vehicle 12 and the fixed buoy hydrological monitoring system 2 are wirelessly communicatively connected. After information exchange, the underwater vehicle 12 exchanges information with other fixed buoy hydrological monitoring systems 2 on the water surface, so that the fixed buoy hydrological monitoring system 2 underwater can communicate with the dynamic monitoring system 4 data-wise, so as to transfer the ocean hydrological information collected by the fixed buoy hydrological monitoring system 2 to the dynamic monitoring system 4 through the underwater vehicle 12, and send the control instructions of the dynamic monitoring system 4 to the fixed buoy hydrological monitoring system 2;

[0064] Step S6, the data analysis module 5 obtains ocean hydrological data based on the fixed buoy hydrological monitoring system 2 and the mobile hydrological monitoring system 3, conducts data analysis, identifies the areas where the fixed buoy hydrological monitoring system 2 and the mobile hydrological monitoring system 3 cannot be deployed on the water surface, sinks the fixed buoy hydrological monitoring system 2 in the areas, and makes the mobile hydrological monitoring system 3 leave the areas;

[0065] Step S7, the data analysis module 7 analyzes the obtained ocean hydrological data, and when the abnormal ocean hydrological information is detected, an alarm is given through the warning alarm module 6.

[0066] Preferably, the data analysis module 5 obtains the temperature difference between the fixed buoy hydrological monitoring systems 2 based on the temperature monitored by each fixed buoy hydrological monitoring system 2, and then generates the navigation path of the corresponding underwater vehicle 12 to make the best use of the temperature difference energy and reduce the use of the energy of the underwater vehicle 12 itself.
