Description

Technical Field

[0001] The invention relates to a marine environment observation device with a communication function and a use method thereof, belonging to the technical field of fixed-point marine environment observation. Background Art

[0002] With the growth of the global population and the increasing depletion of land resources, the development and utilization of marine resources has attracted more and more attention. As one of the important infrastructures for the development of marine resources, the bottom-mounted observation device can stably support the platform and withstand various mechanical loads of the marine environment. It plays a very important role and significance in marine engineering. Based on this, the bottom-mounted observation device is also widely used in the field of marine observation and detection. For example, the deep-sea bottom-mounted observation device can obtain a variety of observation data such as seabed stratum structure, seabed temperature, and seabed water flow.

[0003] Specifically, the bottom-mounted observation device is equipped with various self-contained detection instruments. When it is deployed on the seabed, the various detection instruments inside conduct long-term continuous observations of ocean elements, especially long-term measurements of ocean dynamic parameters, and obtain long-term comprehensive underwater observation data.

[0004] However, the above-mentioned marine environment observation devices, especially the base observation devices, have the following main problems when used in complex environments:

[0005] 1. Difficulty in design and construction: The design and construction of bottom-mounted observation devices need to fully consider the complexity and variability of the marine environment, which increases the difficulty and cost of design and construction.

[0006] 2. Difficulty in maintenance and servicing: Since the bottom-mounted observation device is in the marine environment for a long time, its maintenance and servicing is relatively difficult and requires regular inspection and repair to ensure its normal operation.

[0007] 3. Many risk factors: There are many risk factors in the marine environment, such as ocean currents, waves, storms, etc. These factors may cause damage to the bottom-mounted observation device or affect its normal operation.

[0008] 4. Difficulty in monitoring and management: The monitoring and management of base-mounted observation devices requires a lot of manpower and material resources, as well as advanced monitoring and management technical support to ensure their normal operation and safety.

[0009] 5. Poor safety: When the bottom-mounted observation device sinks to the seabed for observation, the seabed sediments are easily rolled up and gradually covered by the bottom-mounted observation device due to the effects of tides, internal waves and seabed currents. Especially when the seawater is greatly disturbed by typhoons or earthquake waves, the thickness of the seabed sediments changes, which may bury the bottom-mounted observation device. At this time, the bottom-mounted observation device cannot receive the external acoustic release and buoyancy command, resulting in the inability to recover the data and the loss of the bottom-mounted observation device. The bottom-mounted observation device box may also be suspended in the seawater without touching the seabed, and it is easy to be dragged away by fishing nets and lost, eventually causing property loss.

[0010] 6. Poor intelligence: Unable to dynamically adjust the working mode according to changes in the marine environment.

[0011] In summary, there is a need for an ocean environment observation device with communication function that can maintain safe and stable operation in the above-mentioned complex environment. Summary of the invention

[0012] Therefore, the purpose of the present invention is to provide an ocean environment observation device with communication function and a method for using the observation device, so as to realize the timely uploading of equipment data and collected data and improve the effect of ocean environment observation.

[0030] After the seat bottom observation unit detects an abnormal position change, it turns on the noise measurement device, collects environmental noise, analyzes and records noise data, and automatically uploads the characteristic value of the noise;

[0031] When the bottom observation system cannot communicate normally with the water surface observation system, the bottom observation system periodically sends characteristic data through the acoustic communication device.

[0035] When the bottom observation unit flips over, the acquisition control module cannot communicate with the shore-based monitoring unit.

[0043] The present invention is further described in detail below through the accompanying drawings and specific implementation methods. Generally, since the marine environment observation device is used in a complex and special use environment, it is particularly important to maintain data and upload collected data. If the data cannot be fed back in time, the observation effect will be affected and even the normal use of the device will be affected.

[0044] Embodiment 1

[0045] like Figure 1 As shown, the present invention provides a marine environment observation device with communication function, comprising:

[0046] The bottom observation unit includes a bottom platform, an acquisition control module arranged on the platform, an acoustic releaser electrically connected to the acquisition control module, an underwater power supply module, a measurement module, a safety control module (including a release mechanism), an underwater acoustic communicator, a first transducer and a second transducer; the measurement module includes an acoustic Doppler current profiler (ADCP, Acoustic Doppler Current Profilers), a temperature-salinity-depth meter CTD and a noise meter. The measurement data output by the ADCP includes the posture (azimuth, tilt, swing) of the bottom platform. The bottom observation unit is deployed to record and store the posture and water depth of the bottom platform. The first transducer is installed on the upper end surface of the underwater acoustic communicator, and the second transducer is installed on the lower end surface of the underwater acoustic communicator;

[0047] The acquisition control module is used to configure the start / stop of the above-water transducer and the underwater transducer.

[0048] The bottom observation unit adopts two working modes, namely real-time communication and self-contained operation. Real-time communication is used when the bottom observation system deployment point is close to the surface buoy system. It can communicate with the buoy (surface observation unit) through hydroacoustic communication, transmit underwater monitoring data and receive instructions from the shore station (shore-based monitoring unit) to achieve two-way communication. In the real-time communication mode, the underwater system also stores observation data; self-contained operation is used when the bottom observation unit collects marine environment measurement data at preset time intervals before deployment and stores it inside the system. The measurement data is replayed after the underwater system is recovered. The acquisition control module can monitor the battery status, alarm in time for abnormal voltage, and dynamically allocate energy and adjust the sensor sampling frequency to save energy.

[0049] When the bottom observation unit detects an abnormal position of the bottom platform (azimuth, tilt, swaying depth, data changes of the attitude sensor), which is generally caused by the towing of the fishing net, the bottom observation unit immediately reports the abnormal situation to the shore-based monitoring unit so that appropriate measures can be taken in time to deal with it; after the bottom platform detects the abnormal position change, it turns on the noise meter, collects environmental noise, analyzes and records the noise data, and automatically uploads the characteristic value of the noise; if the bottom observation unit cannot communicate normally with the surface observation unit, the bottom observation unit regularly sends status data through the underwater acoustic communicator to facilitate maintenance personnel to search and locate the bottom platform.

[0050] like Figure 2 As shown, the safety control module includes an embedded control submodule (STM32L071), a wireless submodule, a satellite communication submodule, an AIS receiving terminal, a pressure sensor and a power supply submodule;

[0051] The wireless submodule, the satellite communication submodule, and the AIS receiving terminal are fixed on the inner side of the top of the seat bottom observation unit; and the power supply submodule is fixed on the inner side of the bottom of the seat bottom observation unit.

[0052] The safety control unit is designed with positive buoyancy. When the safety control unit floats to the surface, the wireless submodule, satellite communication submodule, and AIS receiving terminal are at the top to ensure normal wireless communication, satellite communication, and AIS signal reception. The above-mentioned pressure sensor is used to detect that the bottom observation unit has floated to the surface of the water, and the current position information is sent to the shore-based monitoring unit through the satellite communication submodule at regular intervals; at the same time, the AIS receiving terminal carried is used to search for nearby AIS information. If there is a ship nearby, the AIS information of the ship is sent to the shore-based monitoring unit.

[0053] The acquisition control module and the safety control module can realize wireless communication through the wireless submodule. The safety control module regularly receives and stores the characteristic values ​​of the measurement data sent by the acquisition control module. Since the wireless communication signal is severely attenuated in water, in terms of structural design, the wireless communication modules of the acquisition control module and the safety control module should be as close as possible to ensure normal communication.

[0054] It should be added here that Figure 3 As shown, the safety control module is placed in the longitudinal release channel inside the base observation unit through the upper end surface; when the base observation unit is turned over, the safety control module is placed in the longitudinal release channel inside the base observation unit through the lower end surface. When the acquisition control module finds that the base observation system is abnormal, the safety control module can be released through the release mechanism, so that the on-site maintenance personnel can recover the safety control module through the location information sent by the safety control module.

[0055] The safety control module is installed in a release channel that is open at the top and bottom. The release mechanism is installed in the middle of the safety control module. Under normal circumstances, the safety control module can be released from the upper release channel. When the seat bottom observation system accidentally flips over, the safety control module can be released from the lower channel.

[0056] Specifically, the acquisition control module can release the safety control module through the release mechanism when the following situations occur:

[0057] 1. After the acoustic releaser issues a release command, if the bottom observation module cannot float normally, it receives a release command from the shore-based monitoring module;

[0058] 2. The set surfacing time is reached, and the underwater acquisition control module cannot communicate normally with the shore-based monitoring system;

[0059] 3. When the bottom observation system accidentally flips over, the underwater acquisition control module cannot communicate normally with the shore-based monitoring system.

[0060] The water surface observation unit includes a buoy and a water surface control module arranged inside the buoy, wherein the control module is electrically connected to a water surface satellite communication terminal, an underwater acoustic communicator and an underwater transducer; the underwater acoustic communicator is communicatively connected with the underwater acoustic communicator; during specific use, the bottom observation unit is placed on the seabed of the working area, while the water surface observation unit is placed on the water surface of the working area.

[0061] Under normal circumstances, the acquisition control module uses the above-water transducer to communicate with the surface observation unit; after the acquisition control module finds that the bottom observation unit has accidentally flipped over through the attitude sensor, the acquisition control module uses the second transducer to communicate with the surface observation unit and reports the flipping of the bottom platform to the shore-based monitoring system; if the underwater platform is flipped over and dragged away from the observation position by a fishing boat and cannot communicate normally with the buoy observation system, the bottom observation system will periodically send characteristic data through the second transducer, and maintenance personnel can search for the characteristic data of the bottom platform through the acoustic communication device they carry, which is convenient for maintenance personnel to locate the bottom platform.

[0062] The surface observation unit is deployed in the observation sea area (i.e., the working area), and the adjacent bottom observation unit is deployed at the predetermined seabed station. The bottom observation unit collects ocean environment measurement data at preset time intervals before deployment, and stores it inside the unit to achieve in-situ observation and measurement of ocean environment parameters such as waves, current profiles, temperature, salinity, and environmental noise; the bottom observation unit transmits the characteristic data of the measured environmental parameters to the surface observation unit through hydroacoustic communication, and can also receive commands sent by the shore-based monitoring unit. After the bottom observation unit is recovered, the measurement data is replayed.

[0063] The shore-based monitoring unit comprises a shore-based monitoring terminal and a shore-based satellite communication terminal which are electrically connected, wherein the shore-based monitoring terminal is bidirectionally connected to the surface satellite communication terminal through the shore-based satellite communication terminal.

[0064] The surface observation unit receives the observation data from the bottom observation unit and sends it to the shore-based monitoring unit. At the same time, the surface observation unit can receive commands from the shore-based monitoring unit and forward them to the bottom observation unit. The surface observation unit communicates with the bottom observation unit through underwater acoustic communication (overwater acoustic communication device and underwater acoustic communication device) to achieve two-way communication control between the surface observation unit and the bottom observation unit.

[0065] The shore-based monitoring unit not only stores, processes and distributes the received observation data, but can also remotely monitor the bottom-based observation unit.

[0066] The shore-based monitoring terminal is configured to switch the working state of the bottom observation unit and the measurement module (sensor) according to the parameter information of the bottom observation unit, reduce or increase the sampling interval of the bottom observation unit and the sensor, stop a certain sensor, etc. For example: encrypt the measurement in special weather phenomena (such as typhoons, tsunamis, etc.); reduce the sampling frequency of the bottom observation unit or sensor when the battery voltage is too low; stop the measurement sensor when the sensor measurement is abnormal. The command format sent by the shore-based monitoring unit is shown in Table 1.

[0067] Table 1 Data format sent by shore-based monitoring unit

[0068] content address Logo Sensor Type Working interval (min) Working hours (minutes) byte 2 1 1 2 2

[0069] Wherein: Address: the address of the bottom platform;

[0070] Sensor type: 1 is ADCP, 2 is CTD, 3 is acoustic communication device, 4 is noise meter, 5 is tide gauge;

[0071] Working interval: the time interval between each power-on of the sensor;

[0072] Working time: The working time of the sensor after each power-on; for multi-byte data, the high byte is in the front and the low byte is in the back by default.

[0073] The base observation unit can autonomously switch the working mode of the base observation unit and the sensor according to the system status and environmental parameters, reduce or increase the sampling interval and sampling time of the base observation unit and the sensor, stop a certain measurement sensor from working, etc.

[0074] The bottom observation unit can set the corresponding threshold by itself, or remotely set the corresponding threshold through the shore-based monitoring unit, as shown in Table 2. When the measurement parameter exceeds the threshold, the sensor measurement is encrypted, and the measured characteristic value is uploaded to the shore-based monitoring unit, while waiting for the shore-based monitoring command and executing it. If there is no command from the shore-based monitoring unit, the normal sampling frequency is restored after the measurement parameter is normal or after 24 hours. The acquisition control unit can collect the battery voltage. When the battery voltage is lower than the set threshold, the sampling frequency of the bottom observation unit or sensor is reduced to save energy; when the sensor measurement is abnormal, the measurement sensor is stopped.

[0076]

[0077] An embodiment of the present invention provides an ocean environment observation device with communication function. By adopting a two-layer communication connection method between a bottom observation unit, a surface observation unit and a shore-based monitoring unit, the environmental parameters and status parameters collected by the bottom observation unit are transmitted to the shore-based monitoring unit via the surface observation unit, thereby solving the inconvenience that the bottom observation unit is located underwater all year round and cannot transmit data in time, and ensuring the timeliness of data transmission.

[0083] When the set floating time is reached and the acquisition control module cannot communicate with the shore-based monitoring unit;

[0084] When the bottom observation unit flips over, the acquisition control module cannot communicate with the shore-based monitoring unit.

[0085] S20: When the base observation unit detects that the base platform position is abnormal, the abnormal information is reported to the shore-based monitoring unit. The base observation unit sets the parameter threshold during the detection process, and / or the parameter threshold is set by the shore-based monitoring unit. And the process of reporting the abnormal information to the shore-based monitoring unit specifically includes:

[0087] After the seat bottom observation unit detects an abnormal position change, it turns on the noise measurement device, collects environmental noise, analyzes and records noise data, and automatically uploads the characteristic value of the noise;

[0088] When the bottom observation system cannot communicate normally with the water surface observation system, the bottom observation system periodically sends characteristic data through the acoustic communication device.

[0089] When the acquisition control module detects that the base observation unit is flipped over through the sensor, the acquisition control unit communicates with the water surface observation unit through the second transducer and reports the flipping information to the shore-based monitoring unit.
