Description

Technical Field

[0002] With the gradual replacement and depletion of conventional fossil energy, the development and utilization of low-carbon new energy such as marine natural gas hydrates has become a general trend, and the corresponding environmental monitoring and evaluation during the mining process has become increasingly important. Natural gas hydrates have certain environmental disaster effects. When the stable environment of their occurrence areas is destroyed, it is easy to cause a series of environmental problems, such as greenhouse effect, submarine landslides, and damage to the marine ecological environment. Therefore, the exploration and development of marine natural gas hydrates must first monitor and evaluate their environmental effects and possible environmental disasters. At present, some marine stereoscopic observation devices are usually used to conduct real-time environmental monitoring of deep-sea natural gas hydrate mining areas.

[0003] In the existing ocean stereoscopic observation device, the sensor monitoring data of the underwater docking box needs to be gathered at the buoy end, and then sent to the shore-based server through GPRS, Iridium and other wireless communication methods on the buoy, so as to realize the real-time stereoscopic ocean data monitoring of the buoy seabed.

[0041] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0042] It should be noted that, although the functional modules are divided in the device schematic diagram and the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first", "second", etc. in the specification, claims and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0044] In this ocean stereoscopic observation device, the sensor monitoring data of the underwater docking box needs to be gathered at the buoy end, and then sent to the shore-based server through GPRS, Iridium and other wireless communication methods on the buoy, so as to realize the ocean stereoscopic real-time data monitoring of the buoy seabed base.

[0045] In the prior art, the communication between the buoy and the docking box is based on the electrical unit or optical unit in the dynamic cable. The dynamic cable also plays the role of a mechanical anchor chain in the buoy seabed base system. The reliability of the three characteristics of the dynamic cable is as follows: mechanical characteristics> electrical unit characteristics> optical unit characteristics. In comparison, the optical unit characteristics, that is, the optical fiber has a higher bending radius requirement for the dynamic cable. When the actual sea conditions are poor, the bending and twisting of the dynamic cable may cause damage to the optical fiber. In a deep water environment (underwater environment with a depth greater than 50 meters), relying solely on optical communication or electrical communication for data transmission between the underwater docking box and the buoy has a great risk of data transmission failure and will reduce the survival rate of the marine stereoscopic observation device.

[0046] Based on this, for deep water environments, the embodiments of the present application propose an ocean stereoscopic monitoring device in deep water environments and its control method and medium, which can improve the data transmission success rate between the docking box and the buoy in deep water environments and improve the survival rate of the ocean stereoscopic monitoring device.

[0047] Reference Figure 1 , Figure 1 This is an optional structural diagram of an ocean stereoscopic monitoring device in a deep water environment provided by an embodiment of the present application. The device may include but is not limited to:

[0048] A docking box module, used to dynamically acquire ocean monitoring data and transmit the ocean monitoring data to a buoy module;

[0049] The buoy module is used to switch the communication channel by using the heartbeat packet judgment mechanism, determine the target communication channel from multiple communication channels, establish the target communication channel with the docking box module, and receive the ocean monitoring data through the target communication channel; the communication channel includes an optical fiber communication channel, an electrical communication channel, and an acoustic communication channel;

[0050] The buoy module is also used to transmit ocean monitoring data to shore-based services via a wireless communication network.

[0051] In some embodiments, the above-mentioned ocean stereo monitoring device adopts a communication architecture with acoustic, optical and electrical redundancy and complementation. Specifically, the ocean stereo monitoring device preferentially selects the optical fiber communication mode for data transmission between the junction box module and the buoy module, and automatically switches to the electrical communication mode when the optical fiber communication fails, and switches to the acoustic communication mode when both the optical and electrical communications fail. The data bandwidths in the three communication modes are different, and the data transmission modes and compression rates are also different. Among them, the acoustic communication bandwidth is the smallest but is not affected by the dynamic cable state. It is used for the transmission of system status, position and key sensor data information in extreme cases. Through the redundancy and complementarity of the three communication modes, the survival rate of the system is maximized.

[0052] In some embodiments, the above-mentioned ocean stereoscopic monitoring device further includes:

[0053] A data analysis module is used to analyze the ocean monitoring data, determine the abnormal data detection results, dynamically adjust the data sampling frequency according to the abnormal data detection results, and generate data sampling control instructions according to the data sampling frequency;

[0054] The ocean data monitoring module is used to receive data sampling control instructions, dynamically collect ocean monitoring data at a data sampling frequency according to the data sampling control instructions, and transmit the ocean monitoring data to the docking box module.

[0055] In some embodiments, the ocean monitoring data includes but is not limited to seawater methane content, dissolved oxygen, total alkalinity, active silicate, active phosphate, nitrate, nitrite, total phosphorus, total nitrogen, total carbon, water depth, water temperature, etc. The data analysis module is used to perform target data anomaly analysis on the ocean monitoring data to determine whether there is abnormal target data, that is, to determine the abnormal data detection result. When the abnormal data detection result is that there is abnormal target data in the ocean monitoring data, the data sampling frequency is dynamically adjusted according to the target abnormality level of the target data.

[0056] The target data can be set according to actual needs. For example, data such as seawater methane content and dissolved oxygen can be set as target data. At the same time, multiple abnormality levels of each target data and the data threshold interval and target data sampling frequency corresponding to each abnormality level are set. Then, the target data sampling frequency corresponding to each target data is obtained, and the highest data sampling frequency is determined from the target data sampling frequencies corresponding to each target data. The highest data sampling frequency is used as the above-mentioned data sampling frequency. Exemplarily, it is determined that the current seawater methane content is abnormally increased. According to the current seawater methane content, the current abnormality level corresponding to the current seawater methane content is determined from multiple abnormality levels. The current seawater methane content is in the data threshold interval corresponding to the current abnormality level. The data sampling frequency corresponding to the current abnormality level is obtained, and the data sampling frequency corresponding to the current abnormality level is used as the above-mentioned data sampling frequency. According to the data sampling frequency, the corresponding data sampling control instruction is generated.

[0058] In some embodiments, the ocean data monitoring module controls the ocean observation equipment according to the observation equipment control instructions. After being controlled by the ocean data monitoring module, the above-mentioned ocean observation equipment performs ocean monitoring tasks in a deep water environment, collects various ocean monitoring data and returns them to the ocean data monitoring module.

[0062] The first control unit is also used to determine whether to switch the target communication channel according to the number of consecutive response failures and a given number threshold;

[0063] The second control unit is used to receive the heartbeat packet, respond to the heartbeat packet, generate a response heartbeat packet, and transmit the response heartbeat packet back to the first control unit through the target communication channel.

[0064] Exemplarily, the first time threshold is T1 seconds, the second time threshold is T2 seconds, the given number threshold corresponding to the consecutive number of response failures is X times, the first control unit sends a heartbeat packet to the second control unit every T1 seconds, and after the second control unit receives the heartbeat packet, it generates a corresponding response heartbeat packet within T2 seconds and returns it to the first control unit. When the first control unit does not receive the response heartbeat packet sent back from the second control unit for X consecutive times, that is, the consecutive number of response failures exceeds the given number threshold, the first control unit determines that the current target communication channel has failed and switches the target communication channel.

[0069] In some embodiments, according to the bandwidth (transmission rate) of the optical fiber communication channel, the electrical communication channel and the acoustic communication channel, the first control unit and the second control unit automatically switch the data mode to adapt.

[0074] The first underwater acoustic transceiver unit is used to connect with the second underwater acoustic transceiver unit, receive the third control instruction, and establish an acoustic communication channel according to the third control instruction.

For example, the buoy module can communicate with the seabed observation base station through the first hydroacoustic transceiver unit. The seabed observation base station is used to monitor the bottom seawater environmental parameter data, and the buoy module receives the ocean environment monitoring data transmitted from the seabed observation base station.
