[0011] A sea-air multi-parameter measurement platform based on a wave glider comprises a surface hull 1, a solar power generation panel 2, a laser wind measurement radar 3, a micro-meteorological station 4, an equipment compartment 5, an atmospheric waveguide measuring instrument 6, an atmospheric waveguide measuring antenna 7, a wave meter 8, a multi-parameter water quality measuring instrument 9, an ADCP device 10, a navigation control compartment 11, a Beidou communication terminal 12, an underwater wave energy propeller 13, an underwater winch 14 and a CTD instrument 15, wherein the laser wind measurement radar 3 is installed at the front of the surface hull 1, the equipment compartment 5 and the navigation control compartment 11 are arranged at the rear of the surface hull 1, the solar power generation panel 2 is laid above the laser wind measurement radar 3, the equipment compartment 5 and the navigation control compartment 11, and the laser sensor on ... and the laser sensor on the laser wind measurement radar 3 is installed at the front of the surface hull 1, the equipment compartment 5 and the navigation control compartment 11 are arranged at the rear of the surface hull 1, and the laser sensor on the laser wind measurement radar 3 is installed at the front of the surface hull 1, the equipment compartment 5 and the navigation control compartment 11 are arranged at the rear of the surface hull 1, and the laser sensor on the laser wind measurement radar 3 is installed at the front of the surface hull 1, the equipment compartment 5 and the navigation control compartment 11 are The sensor is higher than the solar panel 2, the micro-meteorological station 4 and the atmospheric waveguide measurement antenna 7 are installed in the middle of the surface hull 1, the wave meter 8 and the atmospheric waveguide measurement instrument 6 are installed in the equipment compartment 5, the equipment compartment 5 is located in the middle of the surface hull 1, the navigation control compartment 11 is installed in the rear position of the surface hull 1, the ADCP equipment 10 is installed at the tail of the surface hull 1, the Beidou communication terminal 12 is installed in the middle of the surface hull 1, the multi-parameter water quality measuring instrument 9 is installed in the middle of the surface hull 1, the underwater winch 14 is installed in the middle of the underwater wave energy propeller 13, the underwater wave energy propeller 13 is connected to the lower part of the surface hull 1 through a flexible umbilical cable 16, and the CTD instrument 15 is installed on the underwater winch 14. The surface hull 1 is provided with slots for installing the laser wind measurement radar 3, the equipment compartment 5 and the navigation control compartment 11. These instruments are centrally installed in the entire hull of the surface hull 1, reducing the navigation resistance and protecting the safety of the instruments. The flexible umbilical cable 16 includes a traction link for the drive and electrical connections for the instruments.

[0012] The laser wind radar 3, micro-meteorological station 4, wave meter 8, atmospheric waveguide measuring instrument 6, multi-parameter water quality measuring instrument 9, ADCP equipment 10, underwater winch 14 and CTD instrument 15 are connected to the navigation control cabin 11 through the RS485 bus. The data is parsed and packaged by the navigation control cabin 11 and then sent back to the ground through the Beidou communication terminal 12.

[0013] Since this solution has many devices and consumes a lot of electricity, especially the laser wind radar 3, atmospheric waveguide measuring instrument 6, ADCP equipment 10 and underwater winch 14, which consume a lot of power, it is necessary to manage the power supply of these devices. In this example, the total working power of all environmental parameter measurement equipment is about 200W, which is turned on once every 2 hours for 10 minutes each time, and a total of 400Wh of electricity is required in one day. The average power consumption of the wave glider platform's own control and communication is about 8W. It is turned on 24 hours a day, and a total of 192Wh is required in one day. The overall power consumption of the wave glider is about 592Wh in one day. When the weather is fine, the solar panel 2 of the wave glider generates about 800Wh of electricity a day. Therefore, when the weather is fine, the power generated by the solar panel 2 is enough for the platform and equipment. When there are clouds, the solar panel 2 generates about 400Wh of electricity a day. At this time, the working time interval of the environmental parameter measurement equipment is increased, and it is turned on once every 4 hours for 10 minutes each time, and a total of 200Wh of electricity is required in one day. The total daily power consumption of the wave glider is 392Wh. When there are clouds, the power generated by the two solar panels is enough for the platform and equipment by increasing the working time interval of the equipment. Based on the average speed of the wave glider of 2.5 kilometers per hour, the sea and air environmental parameters can be measured at an interval of 5 kilometers in fine weather and at an interval of 10 kilometers in cloudy weather.

[0014] like Figure 1 and Figure 2 As shown, the atmospheric waveguide measuring instrument 6 uses the marine AIS signal to measure the atmospheric waveguide parameters of the ocean surface, the micro-meteorological station 4 is used to measure meteorological data such as atmospheric wind speed and direction, temperature and pressure on the ocean surface, the laser wind measuring radar 3 is used to measure the velocity and direction of air currents in each layer at an altitude of 0-2000 meters above the sea surface, the wave meter 8 is used to measure the frequency, amplitude and direction of waves on the ocean surface, the underwater winch 14 equipped with CTD is used to measure the temperature, salinity and conductivity of seawater at a depth of 10-200 meters, the multi-parameter water quality measuring instrument 9 is used to measure parameters such as dissolved oxygen and chlorophyll in the ocean surface seawater, and the ADCP device 10 is used to measure the velocity and direction of water currents in each layer at a depth of 0-200 meters.

[0015] Since the wave glider (underwater wave energy propeller 13 and surface hull 1) is small in size and has limited carrying capacity, it is necessary to arrange the various instruments and equipment reasonably to maximize the use of the wave glider space and maximize the accuracy of data measurement while ensuring the stability of the platform. In addition, the wave glider generates electricity through the solar panels 2, and the power supplied is limited. It is necessary to reasonably allocate the working hours of various instruments and equipment to maximize the use of electricity. It is necessary to reasonably arrange the various external sensor probes to reduce the occupation and obstruction of the solar power generation area. Since the wave glider relies on wave energy to move forward and has weak power, it is necessary to design the various instruments and equipment and the platform itself in a conformal manner to reduce the navigation resistance of the wave glider.

[0016] In this example, the laser wind radar 3 is placed below the solar panel 2 on the surface hull 1 of the wave glider, and the deck of the surface hull 1 is opened to transmit the laser to maximize the solar power generation area. The wave meter 8 is placed at the center of the surface hull 1 to maximize the accuracy of wave parameter measurement. The ADCP device 10 is placed at the tail of the surface hull 1 to minimize the interference of the underwater wave energy propeller 13 on the sound wave signal of the ADCP device 10. The atmospheric waveguide measurement antenna 7 and the micro-meteorological station 4 are concentrated on the deck position in the middle of the surface hull 1 to minimize the occupation of the solar panel 2 area and improve the stability of the surface hull 1. The water resistance of the wave glider during navigation is reduced by the streamlined design of the underwater winch 14 shell.

[0017] The main body of the laser wind measuring radar 3 is installed below the solar power generation panel 2 , and the laser sensor on the laser wind measuring radar 3 is located higher than the solar power generation panel 2 .

[0018] The underwater winch 14 is installed at the middle position of the lower part of the underwater wave energy propeller 13.

[0019] A moon pool is arranged at the tail of the surface boat 1, and the ADCP device 10 is arranged in the moon pool.

[0020] The sea-air multi-parameter measurement platform operates in different modes according to different lighting conditions. When the weather is sunny, it measures every 2 hours; when it is cloudy, it measures every 4 hours; and when it is cloudy and rainy, it stops measuring.

[0021] The wave meter 8 is installed near the center of the surface boat 1.

[0022] In the above, the ADCP device 10 is an acoustic Doppler current profiler (English: Acoustic Doppler Current Profiler, abbreviated: ADCP), which is a velocity measuring sonar device developed by integrating multiple disciplines such as hydroacoustic physics, hydroacoustic transducer design, electronic technology and signal processing. As an application of hydroacoustic technology, Doppler velocity measurement provides a comprehensive application platform for these related disciplines. The Acoustic Doppler Current Profiler (ADCP) uses the acoustic Doppler principle to measure the frequency shift information of the scattered signal of the layered water medium, and uses the vector synthesis method to obtain the water velocity of the vertical profile of the ocean current, that is, the vertical profile distribution of the water current. It does not produce any disturbance to the tested flow field, and there is no mechanical inertia and mechanical wear. It can measure the three-dimensional components and absolute directions of several layers of velocity on a profile at one time. It is a hydroacoustic flow measurement instrument.

[0023] In national defense construction: whether it is maritime warfare, submarine activities, anti-submarine alert, or shipbuilding, marine military industry, etc., ocean current data are required.

[0024] In terms of marine environmental protection and scientific research: from previous expeditions to modern scientific expeditions, people have not only gradually understood the ocean, but are also moving towards the development and utilization of the ocean. From the perspective of modern oceanography, marine hydrological observation is the most basic component of comprehensive marine surveys, that is, to explore the characteristics of various marine hydrological phenomena, study their changing laws, clarify the causes of these phenomena and their changes, and provide data for navigation safety, marine resource development, marine engineering construction, marine environmental protection and scientific research. In the study of shallow seas on the continental shelf and nearshore estuaries and bays, the "variance method" is used to calculate turbulent parameters such as Reynolds stress and vertical eddy viscosity coefficient from the original velocity data measured by ADCP. Foreign experiments such as the Pomex experiment, the tropical Atlantic experiment, the air mass variability experiment, and the monsoon experiment all belong to this type of experimental research.

[0025] In the national economy: mainly including applications in navigation, fishery production, marine development and utilization, environmental protection, etc. ADCP is used in hydrological surveys of rivers, lakes, oceans, etc. in China. In addition to the flow measurement function, ADCP can also measure the wave parameters of the ocean surface and the concentration of suspended matter in the seawater medium. In particular, the ship-borne ADCP can measure the speed of the ship relative to the seabed.

[0026] ADCP has two major advantages: first, the remote sensing attribute of ADCP, that is, such a small device can measure the profile velocity over a range of more than 1000 meters, which brings great convenience to scientific research, engineering and monitoring work; in addition, ADCP has no moving parts and is therefore resistant to biological adhesion. These characteristics enable ADCP to provide long-term ocean current observations.

[0027] The CTD instrument 15 is a conductivity, temperature, depth measurement system, generally referred to as a temperature, salt, and depth system, which is used to measure the three basic water body physical parameters of the water body: conductivity, temperature, and depth. Based on these three parameters, various other physical parameters, such as the speed of sound, can also be calculated. It is a necessary equipment for the investigation of oceans and other water bodies, and an automatic measuring device for the physical and chemical parameters of seawater. It integrates a temperature sensor, a salinity sensor, and a pressure sensor, which are used to measure the temperature, salinity, and depth of seawater, respectively. The temperature sensor accurately captures the temperature of seawater based on the thermoelectric effect or the principle of resistance change; the salinity sensor obtains seawater salinity information by measuring conductivity and other methods; and the pressure sensor uses water pressure changes to accurately calculate the water depth. These parameters work together to calculate the density and depth of seawater, providing key data support for fields such as marine science, meteorological forecasting, and fisheries. In short, the temperature, salt, and depth sensor plays an irreplaceable role in ocean measurement with its comprehensive and accurate measurement capabilities, and is the core equipment in ocean measurement.
