Technical Field

The present invention relates to the field of ocean wave measurement, and more particularly to an ocean wave measuring device and a method for measuring ocean waves.

Background

The method aims at real-time measurement and even forecast of wind, wave, temperature, flow and other data developed in a target sea area, and is one of important guarantees provided for formation of surface ships and naval vessels. Particularly, the subsequent operation of the ship and the ship formation can be better judged by knowing the sea wave condition of the target sea area in advance. At present, there are four main ways to measure wave height: the buoy type wave height instrument measuring station has high measuring precision, long self-sustaining force, no quick arrangement capability and high cost, and needs to distribute and recover operation ships; the shipborne wave-measuring radar has high measurement precision and long self-sustaining capability, but needs a front ship to sail to a target sea area for measurement, and has high sailing cost, instrument and equipment acquisition cost and maintenance cost; compared with a ship-borne wave-measuring radar mode, the airborne wave-measuring radar can reach a target sea area more quickly, but has low measurement precision, short self-sustaining force, high fuel consumption of an airplane, high acquisition cost of instrument and equipment and high maintenance cost; the satellite telemetering wave measurement can monitor a target sea area for a long time if a geosynchronous satellite is used, the self-sustaining power is long, but the measurement precision is poor, and the cost of an optical sensor and an analysis system is high.

Focusing on the difficult problem of 'quick and accurate measurement of wave parameters', a technical scheme which can be used for carrying out mass scattering in a target sea area and quickly and accurately obtaining wave data in the target sea area so as to provide safety guarantee for formation navigation of surface ships and naval vessels is needed.

Detailed Description

The present invention will be described in detail below with reference to the attached drawings, and the features of the present invention will be further apparent from the following detailed description.

The following detailed description refers to the accompanying drawings that illustrate exemplary embodiments of the invention. The scope of the invention is not, however, limited to these embodiments, but is defined by the appended claims. Accordingly, embodiments other than those shown in the drawings, such as modified versions of the illustrated embodiments, are encompassed by the present invention.

References in the specification to "one embodiment," "an example embodiment," etc., indicate that the embodiment may include a particular feature, structure, or characteristic, but every embodiment may not necessarily include the particular feature, structure, or characteristic. Moreover, such phrases are not necessarily referring to the same embodiment. Further, when a particular feature, structure, or characteristic is described in connection with an embodiment, it is submitted that it is within the knowledge of one skilled in the relevant art to effect such feature, structure, or characteristic in connection with other embodiments whether or not explicitly described.

The wave measuring device has the measuring precision and the self-sustaining force which are not lower than those of a buoy type wave height instrument measuring station and a ship-borne wave measuring radar. In addition, the inflatable air bag at the upper part of the electronic cabin and the heavy hammer at the lower part of the electronic cabin of the sea wave measuring device enable the sea wave measuring device to be kept vertical in the waves as much as possible, and therefore more accurate wave height data can be obtained. In addition, the sea wave measuring device can be combined with a landing device, and a large amount of scattering is rapidly distributed to a target sea area from a naval vessel, so that the sea data of the target sea area can be rapidly and conveniently known. In addition, the sea wave measuring device is provided with the self-destruction device, so that zinc alloy at the bottom is corroded after ocean data are obtained, the sea wave measuring device is self-destroyed and does not need to be recycled, and navigation cost, instrument and equipment recycling cost, maintenance cost and the like can be saved.

Fig. 1 shows a schematic representation of a wave measuring device 100 according to an embodiment of the invention in an undeployed state. The wave measuring device 100 includes an electronic compartment 101 and a weight 102 attached to the bottom of the electronic compartment 101. According to one embodiment of the invention, the electronics pod 101 is a swivel-shaped electronics pod. According to another embodiment of the present invention, the weight 102 is used to lower the center of gravity of the wave measurement device 100, and improve its stability in the waves. Those skilled in the art will appreciate that the shape, material and weight of the weight 102 may vary from practice to practice.

Fig. 2 shows a representation of a wave measuring device 100 according to an embodiment of the invention in a deployed state. The wave measuring device 100 enters a deployed state when operating at the sea surface. Wherein, in the unfolding state, the inflatable air bag 106 arranged at the upper part of the electronic cabin 101 is inflated and extends out of the electronic cabin 101 to surround the upper part of the electronic cabin 101, thereby providing buoyancy for the sea wave measuring device 100. The support rod 104 extends from the inside of the electronic cabin 101, and pushes the antenna 103 to ascend for signal transceiving. The weight 102 is released downwards and connected to the electronic compartment 101 via the cable 105. Thus, once the wave measurement device 100 enters the deployed state, it can float on the surface for data acquisition and transmission. Particularly, under the matching use of the inflatable airbag 106 installed at the upper part of the electronic cabin 101 and the weight 102 below the electronic cabin 101, the sea wave measuring device 100 can be kept as vertical as possible in the sea wave, and more accurate sea wave data can be obtained.

According to one embodiment of the present invention, the weight 102 is attached to the bottom of the electronic compartment 101 by a cable 105. According to an embodiment of the present invention, one end of the cable 105 is connected to the bottom of the electronic cabin 101, and the other end is connected to the weight 102, and the cable 105 may be built in the electronic cabin 101 or may be built in the weight 102. When the wave measuring device 100 is in the deployed state, the weight 102 is separated from the electronic compartment 101 and released downward with the cable. Those skilled in the art will appreciate that the length of cable 105 may vary depending on the actual requirements.

Figure 3 shows a detailed view of the electronics bay 101 according to one embodiment of the present invention. Referring to fig. 3, the electronic compartment 101 may include sensors 107, an inflation system 108, a signal system 109, a control unit 110, a power source 111, and a self-destruct device 112. Communication and data transfer between the above components may be accomplished in a variety of suitable ways by those skilled in the art. Further, those skilled in the art will appreciate that the functional blocks depicted in fig. 3 may be combined into a single functional block or divided into multiple sub-functional blocks.

Those skilled in the art will appreciate that the support rods 104 and cables 105 may be housed within the electronics compartment 101 in an undeployed state, as described above with respect to fig. 1 and 2. For clarity of illustration, in fig. 3, the support bar 104 and cable 105 are not shown.

According to an embodiment of the present invention, after the wave measurement device 100 is launched into the target sea area, the inflatable airbag 106 is inflated in time under the actions of the sensor 107, the inflation system 108 and the control unit 110, so that the wave measurement device 100 is not submerged into the sea. At the same time, the signal system 109 processes the marine information collected by the sensors 107 and transmits the processed data via the antenna 103 to a target vessel or other target device (such as an aircraft, a land control system, etc.). Upon reaching the mission time limit, the wave measuring device 100 ceases operation. Under the action of the self-destruction device 112, the wave measurement device 100 can be self-destroyed in the sea without being recycled. According to an embodiment of the present invention, it is fully understood by those skilled in the art that the control unit 110 controls the signal transmission between the above-mentioned components in the electronic compartment 101 and performs the triggering of the functions according to a pre-compiled program.

According to one embodiment of the invention, the sensors 107 may include one or more sensors for sensing physical parameters of the ocean and of the interior of the electronic cabin, such as a 3-way acceleration sensor 107-1, a liquid level sensor 107-2, a pressure sensor 107-3, a water temperature sensor 107-4, an air temperature sensor 107-5, and the like. In practice, the wave measurement device 100 may include one or more of the above-described sensors, or other sensors, depending on the marine environment of different sea areas or different actual requirements. At the same time, it is fully understood by those skilled in the art that the one or more sensors 107 may be installed at different locations of the electronic compartment 1 according to actual needs to obtain more accurate sensing data.

According to one embodiment of the present invention, the charging system 108 includes a high pressure compressed gas cylinder 108-1, a solenoid valve 108-2, and a gas conduit 108-3. The inflation system 108 cooperates with the sensor 107 and the control unit 110 to inflate the airbag 106.

According to an embodiment of the present invention, when the balloon 106 is inflated, the gas can be transmitted along the airway in the electronic compartment, so that the support rod 104 pushes up and the weight 102 releases downward under the action of the gas.

According to one embodiment of the invention, the signal system 109 comprises a signal processing device 109-1 and a signal transmitter 109-2. The signal processing means 109-1 processes the sensed data received from the sensor 107, and the signal transmitter 109-2 is used to transmit the data processed by the signal processing means 109-1 through the antenna 103. According to one embodiment of the present invention, the signal processing apparatus 109-1 includes a core computer control circuit board (STM 32). The signal transmitter 109-2 may employ a Beidou satellite communication device for transmitting and receiving signals.

According to one embodiment of the present invention, since the wave measuring device 100 is a self-destructible device and needs to operate in the ocean for a period of time, the power source 111 may employ a battery that is not rechargeable and has a high battery capacity. For example, a lithium subcell or a lithium manganese cell may be employed according to actual needs.

According to one embodiment of the invention, the self-destruct device 112 is mounted at the bottom of the electronic compartment 101, has a zinc alloy metal plug, and can be corroded by seawater without recycling.

Fig. 4 shows an undeployed schematic view of a wave measuring device 100 with a landing gear 200 installed in accordance with one embodiment of the invention. In practice, in order to know the wave condition of the target sea area in advance so as to better plan the operation of the next ships and vessels formation, a first ship usually arrives at the target sea area in advance for field wave detection. However, this approach involves some risk to the leading vessel and is costly to sail. Accordingly, the present invention combines the wave measuring device 100 with the landing gear 200 such that the wave measuring device 100 can be launched from an aircraft into a target sea area in large quantities, thereby rapidly obtaining large quantities of ocean data for timely transmission back to a target vessel (e.g., a command ship) in a fleet of vessels.

Referring to fig. 4, the landing apparatus 200 can be attached to and detached from the wave measuring device 100 by the landing apparatus attachment 114 at the top of the electronic compartment 101. According to one embodiment of the invention, the landing device attachment 114 is part of the electronics bay 101 and is mounted above the antenna 103. According to another embodiment of the present invention, the landing device attachment 114 is detachably mounted to the top of the electronics bay 101.

Further, according to an embodiment of the present invention, the parachute apparatus 200 may be a parachute. After the wave measurement device 100 is airdropped from the aircraft, the parachute is opened to reduce the descent speed of the wave measurement device 100, so that the wave measurement device 100 is not thrown to the sea surface at an excessive speed, and the purpose of protecting the wave measurement device 100 is achieved. When the wave measuring device 100 contacts the water surface, the parachute can be detached from the wave measuring device 100. The particular manner of connecting and disconnecting the descent apparatus 200 to the wave measurement device 100 is not within the scope of the invention and any suitable manner may be employed by those skilled in the art to achieve this function. Also, those skilled in the art will appreciate that the size, shape, material and style of the drop device 200 can be selected according to specific practices.

FIG. 5 shows a schematic diagram of a method of inflating the bladder 106, according to one embodiment of the present invention. When the wave measuring device 100 is thrown down by a parachute, the falling process generates certain acceleration and speed, and the time for inflating the air bag 106 is very important. For example, if the air bag 106 is inflated after entering the sea surface, the wave measuring device 100 may sink to the sea and become unable to float due to an excessive descent speed. By adopting the inflation mode of the invention, the sea wave measuring device 100 can be inflated in time when contacting the sea surface, so that the sea wave measuring device 100 can safely float on the sea surface for working.

According to an embodiment of the present invention, when the wave measurement device 100 contacts the sea surface, the acceleration sensor 107-1 senses the change in acceleration, so as to receive the information of the resistance caused by the water contact of the electronic cabin 101, and the liquid level sensor 107-2 senses the change in liquid level, and the two sensors together generate a signal that the wave measurement device 100 contacts the sea surface and transmit the signal to the control unit 110. The control unit 110 controls the solenoid valve 108-2 to open based on the received signal. With the solenoid valve 108-2 opened, the high pressure compressed gas cylinder 108-1 starts to operate, and the air bag 106 is continuously inflated through the air duct 108-3. When the air bag 106 is inflated to a certain saturation, the pressure sensor 107-3 transmits a pressure signal to the control unit 110 based on the sensed pressure (for example, the pressure exceeds a predetermined threshold), and the control unit 110 controls the electromagnetic valve 108-2 to close based on the received pressure signal, so that the high-pressure compressed air bottle 108-1 stops working and does not inflate the air bag 106 any more. Therefore, the control unit 110, the high-pressure compressed gas cylinder 108-1, the electromagnetic valve 108-2, the air bag 106 and the pressure sensor 107-3 form a dynamic self-adaptive state, and the opening and closing of the electromagnetic valve 108-2 are controlled in time, so that the air bag 106 is favorably ensured to be inflated.

According to one embodiment of the invention, the airbag 106 can fully or semi-surround the upper part of the electronic cabin 101 after being inflated, so that the wave measuring device 100 can float on the sea surface.

According to one embodiment of the present invention, when the high pressure compressed gas cylinder 108-1 inflates the airbag 106, the released gas may be transferred within the electronics compartment 101 along a gas conduit arranged within the electronics compartment 101 such that: under the action of gas, (1) the supporting rod 104 extends upwards out of the electronic cabin 101 to push the antenna 103 to ascend; (2) the weight 102 is released downward. Wherein the support rod 104 and the weight 102 can be attached to the electronic compartment 101 in a suitable manner (e.g., magnetically, etc.) so as to be movable under the action of the gas.

FIG. 6 shows a schematic diagram of a method for collecting and transmitting ocean data according to one embodiment of the present invention. According to one embodiment of the invention, the sensor 107 collects ocean data when the wave measuring device 100 is operating in the sea, and transmits the collected ocean data to the signal processing device 109-1 for processing and encryption. The signal processing device 109-1 then passes the encrypted data to the signal transmitter 109-2 for transmission via the antenna 103.

In order to accurately predict the ocean information of the target sea area, the accuracy of the ocean wave data obtained by the ocean wave measuring device 100 is particularly important. In general, roll may occur during the time the wave measuring device 100 floats with the wave, and thus, the data in the Z-axis (i.e., vertical) direction may be less accurate, resulting in wave height data that is more different from the actual situation.

According to an embodiment of the present invention, since the wave measuring device 100 uses the weight 102, the wave measuring device 100 can be kept as vertical as possible while floating on the sea surface. In addition, by using the 3-direction acceleration sensor 107-1, data in the Z-axis direction can be collected directly better, noise data in the X-axis and Y-axis directions is reduced, and thus higher-quality wave height data is obtained.

According to one embodiment of the invention, the 3-direction acceleration sensor 107-1 is used in cooperation with an STM32 single chip microcomputer included in the signal processing device 109-1 to move up and down along with waves along with the wave measuring device 100. The signal processing device 109-1 calculates the vertical displacement distance (i.e., the wave height) of the Z axis from the Z-axis acceleration value measured by the 3-direction acceleration sensor 107-1, and thereby can determine the period and the vector wave direction of the vertical displacement (i.e., the wave height) of the sea wave. Specifically, according to an embodiment of the present invention, assuming that the sampling rate of the 3-direction acceleration sensor 107-1 is 5 times/second, the sampling interval is 200ms, and the measurement period is 10 minutes (i.e., 600 seconds), 3000 acceleration values of the Z axis can be acquired in one measurement period. According to the 3000Z-axis acceleration values, the up-down displacement distance X (i.e., the wave height) of the Z-axis can be calculated by twice integration, i.e., X ═ integral ═ a dt. Based on the wave height X, 1/3 effective wave height, 1/3 effective wave period, and maximum wave height can be obtained. 1/3 effective wave height means that, within a 10 minute measurement period, the maximum 1000 wave height data among 3000 wave height data are filtered out as the effective wave height calculation. 1/3 valid wave period means that, within a 10 minute measurement period, the maximum 1000 wave height data among 3000 wave height data are filtered out as valid wave height period calculation. The maximum wave height means that a maximum of 1 wave height data is filtered out of 3000 wave height data as the maximum wave height in a 10 minute measurement period. The vector wave direction is the moving direction of the wave calculated by using the X and Y acceleration values collected by the 3-direction acceleration sensor 107-1. Of course, it is fully understood by those skilled in the art that the above sampling rate, sampling interval, measurement period, etc. can be adjusted according to actual requirements, and the above data are merely examples and are not intended to limit the scope of the present invention.

Furthermore, according to another embodiment of the present invention, in practice, the marine surveying device 100 may additionally use an additional sensor 107 (such as the air temperature sensor 107-5, the water temperature sensor 107-4, etc. mentioned above) to sense the environmental conditions of the sea area such as air temperature, water temperature, etc. according to the marine environment of different sea areas or different actual requirements, thereby obtaining more comprehensive marine data. In consideration of transmission security, the signal processing device 109-1 encrypts the calculated data or the data measured by the sensor to obtain encrypted marine data. The encrypted ocean data may include, for example, one or more of encrypted wave height, wave height period, vector wave direction, air temperature, or water temperature.

The signal processing device 109-1 passes the encrypted marine data to the signal transmitter 109-2, which transmits the encrypted marine data via the antenna 103 to a target vessel or designated target device for subsequent analysis and processing.

Fig. 7 shows a flow diagram of a method 700 of making a wave measurement according to an embodiment of the invention. In step 701, a wave measuring device is launched into a target sea area. According to one embodiment of the invention, one or more wave measuring devices can be launched from the aircraft into the target sea area according to actual demand.

In step 702, the landing apparatus of the wave measuring device is opened to descend toward the target sea area.

In step 703, the wave measuring device is submerged. According to one embodiment of the invention, upon entry of the sea wave measuring device into the water, the following sub-steps may occur: inflating the inflatable bladder 106; the landing device 2 is automatically separated from the wave measuring device 100; releasing the weight 102; antenna 103 extends from within electronics compartment 1. In practice, the above sub-steps may occur simultaneously or nearly simultaneously at the moment the wave measuring device enters the water, so that the wave measuring device can float in the vertical state in the waves as soon as possible after entering the water, and can transmit the ocean data in time.

At step 704, the wave measuring device obtains ocean data. According to one embodiment of the invention, the wave measuring device is capable of obtaining encrypted sea data as described above with reference to fig. 6, including, for example, encrypted one or more of wave height, wave height period, vector wave direction, air temperature or water temperature in relation to the target sea area.

In step 705, the ocean wave measuring device transmits ocean data. According to one embodiment of the invention, the encrypted marine data may be transmitted to a target vessel or other target device via a communication system such as the Beidou satellite communication system.

At step 706, it is determined whether a task execution time limit has been reached. According to one embodiment of the invention, the operating time limit of the wave measuring device may be predetermined, such as the time during which the wave measuring device can be allowed to operate continuously. According to another embodiment of the invention, a task execution time limit may be considered to be reached when the capacity of the power supply is below a predetermined threshold. According to yet another embodiment of the invention, the mission execution limit may be considered to be reached when the wave measuring device fails to function properly due to equipment conditions (e.g., damage caused after a collision, air leakage from an inflated airbag, etc.). If the mission execution time limit is not reached, the wave measurement device loops to step 704 and 706 until the mission execution time limit is reached, and then proceeds to step 707.

In step 707, upon determining that the mission execution limit is reached, the wave measurement device is deactivated. According to one embodiment of the invention, over time, the wave measuring device can be self-destructed without being recycled under the action of the bottom self-destruct device.

The above embodiments are only used for illustrating the technical solutions of the present application, and not for limiting the same; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present disclosure, and the present disclosure should be construed as being covered by the claims and the specification.
