[0002] With the development of monitoring and mapping technology in recent years, new monitoring equipment and technologies have emerged, and many regions have begun to use various sensor technologies to detect nearshore sea ice thickness.

[0041] It should be understood that the various forms of processes shown above can be used, with steps reordered, added, or deleted. For example, the steps described in this invention can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution of this invention can be achieved, and this is not limited herein.

[0042] Figure 1 This is a schematic diagram of an ice thickness measuring device provided in an embodiment of the present invention, specifically used in situations where it is necessary to measure the thickness of ice in a specific sea area.

[0043] refer to Figure 1 This invention provides an ice thickness measuring device, including a power supply component 1, a float assembly 2, a measuring component 3, an analysis and calculation component 4, and a wireless transmission component 10. The measuring component 3 includes multiple acceleration sensors 31 arranged sequentially along a direction perpendicular to the water surface 5 to be measured. The power supply component 1 is connected to the analysis and calculation component 4 and supplies power to the analysis and calculation component 4. Both the power supply component 1 and the analysis and calculation component 4 are encapsulated within the float assembly 2, which supports the power supply component 1 and the analysis and calculation component 4 and floats on the water surface 5 to be measured. The wireless transmission component 10 is connected to the analysis and calculation component 4. The measuring component 1 is located below the water surface 5 to be measured and is fixedly connected to the float assembly 2. When the thickness of the ice layer 6 increases, the acceleration sensors 31 are confined within the ice layer 6 under the action of the ice layer 6. The analysis and calculation component 4 determines the number of confined acceleration sensors 31 based on the acceleration signals fed back by the acceleration sensors 31, thereby calculating and measuring the thickness of the ice layer 6, and transmitting the measured ice thickness information to the user terminal through the wireless transmission component 10.

[0044] Specifically, the accelerometer 31 is a sensor capable of measuring the acceleration of an object. During motion, acceleration is obtained by measuring the inertial force of the mass and Newton's second law. Depending on the sensor's sensitive element, common accelerometers include capacitive, inductive, and strain gauge types. By measuring gravitational acceleration, the tilt of the device relative to the horizontal plane can be calculated, and the device's motion can also be calculated by analyzing dynamic acceleration. In this embodiment of the invention, the accelerometer 31 can be an accelerometer for an adaptive cruise control (ACC) system.

[0045] Before ice layer 6 forms in the water surface 5 to be measured, the float assembly 2 is placed on the water surface 5. Due to buoyancy, the float assembly 2 will float on the water surface 5. When the temperature of the water surface decreases, ice layer 6 will form on the surface of the water surface 5. The float assembly 2 will be fixed on the water surface 5 under the action of the ice layer 6. The measuring component 3 is set below the water surface 5 and fixedly connected to the float assembly 2. As the thickness of the ice layer 6 increases, the accelerometer 31 will be trapped inside the ice layer 6. In this way, the amount of motion of the accelerometer 31 in the three coordinate axis directions is relatively reduced (at this time, the accelerometer 31 will not move with the flowing water). The accelerometer 31 will send a feedback signal to the analysis and calculation component 4. The analysis and calculation component 4 determines the number of trapped accelerometers 31 based on the acceleration signal fed back by the accelerometer 31, thereby completing the measurement of the thickness of the ice layer 6.

[0046] Optionally, the analysis and computing component 4 is integrated on a printed circuit board, which also includes a main chip (processing logic algorithms between various chips), a communication chip (sending and receiving external signals), a storage chip (managing sensor data and storing computer board programs), a power control chip, and so on.

[0047] The ice thickness measuring device provided in this embodiment of the invention encapsulates both the power supply component and the analysis and calculation component within a float assembly. The float assembly floats on the surface of the water to be measured. When the ice thickness increases, the analysis and calculation component determines the number of trapped accelerometers based on the signals fed back by the accelerometers, thereby realizing the measurement of the ice thickness and transmitting the ice thickness information to the user terminal. Through uninterrupted signal transmission, the ice thickness and changes in the water area can be monitored for a long time without the need for multiple on-site surveys by personnel.

[0048] Figure 2 This is a schematic diagram of an ice thickness measuring device provided in an embodiment of the present invention. (Refer to...) Figure 2 Optionally, the measuring component 3 also includes a flexible scale 32, a roller 33, and a plumb line 34; the first end of the flexible scale 32 is connected to the underwater side of the float assembly 2, and the second end of the flexible scale 32 is connected to the roller 33; the second end of the roller 33 is connected to the plumb line 34, and the roller 33 has an internal telescopic structure, which is used to drive the extension and retraction of the flexible scale 32 according to the water depth; the plumb line 34 is used to keep the measuring component 3 always in the first direction Z; wherein, the first direction Z is perpendicular to the water surface 5 to be measured.

[0049] Specifically, the flexible ruler 32 is a measuring tool made of soft material that can be bent without easily breaking. The roller 33 has an internal telescopic structure. The roller 33 is used to drive the flexible ruler 32 to extend and retract according to the depth of the water surface 5 to be measured, so as to adapt to different depths of the water surface 5 to be measured. The plumb line 34 is a tool or method that uses the direction of gravity to determine the vertical line. By using the plumb line 34, the flexible ruler 32 can be fully extended in the water surface 5 to be measured at different depths, thereby increasing the accuracy of measuring the thickness of the ice layer 6. The ice layer thickness measuring device, by setting the roller 33 and the plumb line 34, can adapt to the sea ice layer thickness measurement scenario caused by different depths due to tides by using the adaptive line winding principle.

[0050] Figure 3 This is a schematic diagram of the roller structure in the ice thickness measuring device provided in this embodiment of the invention. (Refer to...) Figure 3 The adaptive wire take-up principle is as follows:

[0051] A coil spring 13 (dynamic spring) is added inside the shaft. When the flexible scale 32 is pulled out, the elastic force of the coil spring 13 will cause it to tend to coil back to its original position. The center is a fixed wheel 12, the outer part is a rotating wheel 11, and they are connected by the coil spring 13 in the middle.

[0052] Optionally, the flexible scale 32 has a strip-shaped sealed structure; the acceleration sensors 31 are arranged sequentially and at equal intervals inside the flexible scale 32.

[0053] The flexible scale 32 is designed with a strip-shaped sealed structure, and multiple equally spaced accelerometers 31 and their signal lines (not shown in the signal line diagram) are encapsulated inside, thereby ensuring that the accelerometers 31 and the signal lines are not corroded.

[0054] The principle for measuring the thickness of ice layer 6 is as follows:

[0055] Analysis revealed that the number of accelerometers 31 imprisoned by the ice layer 6 is m, and the spacing between each accelerometer 31 is p. The thickness of the ice layer 6 can be obtained by calculating the length of mp. The total number of accelerometers 31 is set to n, and the thickness of the unfrozen water surface 5 to be measured is (nm)p.

[0056] Optional, continue to refer to Figure 1 and Figure 2 The ice thickness measuring device provided in this embodiment of the invention also includes a photovoltaic module 7; the photovoltaic module 7 is located above the water surface 5 to be measured and is fixedly connected to the float assembly 2, and the photovoltaic module 7 is connected to the power supply assembly 1; the photovoltaic module 7 converts light energy into electrical energy and charges the power supply assembly 1.

[0057] Specifically, the photovoltaic module 7 is a device that converts light energy into electrical energy. In this embodiment of the invention, a photovoltaic module 7 is also provided to continuously charge the power supply component 1 (which can be a battery, such as a lithium battery), thereby increasing the battery life of the ice thickness measuring device. For example, the photovoltaic module 7 can be a monocrystalline silicon solar panel, a polycrystalline silicon solar panel, a thin-film solar panel, etc. The present invention does not limit the material of the photovoltaic module 7.

[0058] Optional, continue to refer to Figure 1 and Figure 2 The measurement component 3 is connected to the analysis and calculation component 4; the signal lines of the measurement component 3 and the analysis and calculation component 4 are connected through the plug-in terminal 8, and the analysis and calculation component 4 obtains the number of the trapped acceleration sensors 31 in real time through the plug-in terminal 8.

[0059] Specifically, the plug-in terminal 8 is an electrical connection component widely used in power, electric vehicle charging, rail transportation, and other fields. Plug-in terminals 8 are accessories used to connect wires in electrical systems, playing a crucial role in ensuring the safety and reliability of power transmission and signal transmission. The analysis and calculation component 4 uses plug-in terminals 8 to obtain the number of trapped accelerometer sensors 31 in real time. The signal lines of the measurement component 3 and the analysis and calculation component 4 are connected via plug-in terminals 8, allowing the flexible scale 32 to be connected to the internal circuitry (not shown in the figure) via plug-in terminals 8. Flexible scales 32 of different lengths can be replaced according to different length requirements.

[0060] Optional, continue to refer to Figure 1 and Figure 2 The measuring component 3 and the float assembly 2 can be interchangeably connected.

[0061] Specifically, the measuring component 3 can be interchangeably connected to the float assembly 2 via the sealing sleeving 9. By using the sealing sleeving 9 to seal and fix the float assembly 2, not only can water seep into the water surface 5 to be measured, but the flexible scale 32 can also be replaced in a timely manner.

[0062] Optional, Figure 4 This is a top view of an ice thickness measuring device provided in an embodiment of the present invention. The float assembly 2 is one of a disc shape, a block shape, or a strip shape, and the material of the float assembly 2 is molded polystyrene board.

[0063] Specifically, the float assembly 2 can be disc-shaped (e.g., Figure 4 (as shown), one of the following shapes: block or strip; the material of the float assembly 2 can be molded polystyrene board, which generates a large buoyancy that allows the entire device to float on the water surface 5 to be tested.

[0064] Optionally, the weight of the plumb bob 34 is less than the buoyancy force on the float assembly 2; the length of the flexible scale 32 is less than the water depth.

[0065] Specifically, the weight of the plumb bob 34 is set to be less than the buoyancy of the float assembly 2 to prevent the ice thickness measuring device from sinking when measuring ice thickness.

[0073] The ice thickness measurement method provided in this embodiment of the invention can achieve the same technical effect as the ice thickness measurement device provided in the above-described embodiments of the invention, and will not be described again here.

[0074] Optionally, the analysis and calculation component for detecting the operating status of the accelerometer also includes:

[0075] S7: If at least one accelerometer is detected to be faulty, the wireless transmission component sends an alarm signal to the user terminal.

[0076] Specifically, when at least one accelerometer is detected to be faulty, the wireless transmission component sends an alarm signal to the user terminal to remind staff that the ice thickness measuring device has malfunctioned and should be replaced in time.

[0077] Optionally, detecting the acceleration signal fed back by the adjacent acceleration sensor includes:

[0078] When the acceleration signals fed back by adjacent acceleration sensors are 0 or the same, it is determined that there are signals of the same frequency between adjacent acceleration sensors.

[0079] When the acceleration signals fed back by adjacent accelerometers are different, it is determined that there are no signals with the same frequency between adjacent accelerometers.

[0080] Specifically, when the acceleration signals fed back by adjacent accelerometers are 0 or the same, it is determined that the adjacent accelerometers have signals of the same frequency. At this time, the accelerometers are trapped by the ice layer. When the acceleration signals fed back by adjacent accelerometers are different, it is determined that the adjacent accelerometers do not have signals of the same frequency. At this time, the accelerometers are not trapped by the ice layer.
