Description

Technical Field

[0001] This invention relates to the field of magnetic attraction control technology, and in particular to a magnetic attraction control method, device, conference tablet and storage medium. Background Technology

[0002] External modules on the top of the conference tablet, such as camera or microphone modules, are typically secured to the screen frame via a USB or Type-C interface using the magnetic force of a permanent magnet. Permanent magnets are located at corresponding positions on the top of the conference tablet and the bottom of the module, serving as guides and magnets to hold the module in place. However, due to the characteristics of permanent magnets, the closer the module is to the conference tablet, the stronger the magnetic force becomes (see the graph showing the relationship between magnetic force and distance). Figure 1 This results in a poor user experience when inserting the module. The insertion and extraction force is relatively small at the beginning and increases as you get closer, leading to an uneven insertion and extraction force. Summary of the Invention

[0003] This invention provides a magnetic attraction control method, device, conference tablet, and storage medium. By setting a magnetic component on the conference tablet, the magnetic attraction between the module and the magnetic component can be dynamically adjusted according to the distance between the module and the conference tablet, so that the module can be inserted and removed smoothly, improving the user's insertion and removal experience.

[0004] According to one aspect of the present invention, a magnetic attraction control method is provided, applied to a conference tablet, wherein at least one magnetic element is provided in a preset position area of ​​the conference tablet, the method comprising:

[0005] During the process of inserting the target module into or removing it from the conference tablet, the current distance between the target module and the conference tablet is detected in real time.

[0006] Based on a preset functional relationship between the target magnetic attraction force and the target distance, and the current distance, the current magnetic attraction force corresponding to the current distance is determined; wherein, the target magnetic attraction force is the magnetic attraction force between the target module and the magnetic component, and the target distance is the distance between the target module and the magnetic component;

[0007] The magnetic attraction force between the target module and the magnetic component is controlled to be the current magnetic attraction force.

[0008] According to another aspect of the present invention, a magnetic attraction control device is provided, disposed on a conference tablet, wherein at least one magnetic element is provided in a preset position area of ​​the conference tablet, the device comprising:

[0009] The current distance detection module is used to detect the current distance between the target module and the conference tablet in real time during the process of inserting the target module into the conference tablet or removing it from the conference tablet;

[0010] The current magnetic attraction force determination module is used to determine the current magnetic attraction force corresponding to the current distance based on a preset functional relationship between the target magnetic attraction force and the target distance and the current distance; wherein, the target magnetic attraction force is the magnetic attraction force between the target module and the magnetic component, and the target distance is the distance between the target module and the magnetic component;

[0011] The magnetic attraction force control module is used to control the magnetic attraction force between the target module and the magnetic component to the current magnetic attraction force.

[0012] According to another aspect of the present invention, a conference tablet is provided, wherein at least one magnetic element is disposed in a predetermined position area of ​​the conference tablet, the conference tablet comprising:

[0013] At least one processor; and

[0031] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0032] It should be noted that the terms "first," "second," "target," etc., used in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0033] Example 1

[0034] Figure 2 This is a flowchart of a magnetic attraction control method provided in Embodiment 1 of the present invention. This embodiment is applicable to situations where the magnetic attraction between a conference tablet and a pluggable module is dynamically adjusted. The method is applied to a conference tablet, wherein at least one magnetic element is provided in a preset position area of ​​the conference tablet. The method can be executed by a magnetic attraction control device, which can be implemented in hardware and / or software. This magnetic attraction control device can be configured in a conference tablet with data processing capabilities. Figure 2 As shown, the method includes:

[0035] S110 detects the current distance between the target module and the conference tablet in real time during the process of inserting or removing the target module into the conference tablet.

[0036] The target module refers to the module that needs to be fixed to the upper part of the conference tablet. Optionally, the target module includes a camera module and a microphone module. The conference tablet is a product designed for modern digital conference room applications. It uses a high-definition LCD screen as the display and operation platform and integrates multiple functions such as electronic whiteboard, wireless projection, remote conferencing, and high-definition display. At least one magnetic component (e.g., an electromagnet) is provided in a preset location area of ​​the conference tablet. In this embodiment, the distribution location and number of magnetic components are not specifically limited and can be set according to actual needs. Specifically, taking an electromagnet as an example, the strength of the electromagnet's magnetic force is affected by various factors, including the Gauss value of the iron core, voltage, current, and the number of coil turns. The greater the current intensity, the greater the required wire thickness, i.e., the stronger the magnetic force. A magnetic force generated in the opposite direction of the current will also be reversed. The current distance can refer to the distance between the target module and the conference tablet at the current moment.

[0037] It should be noted that the distance between the target module and the conference tablet usually changes in real time during the process of inserting or removing the target module, therefore, real-time distance detection is necessary. For example, distance detection can be performed using a distance sensor or camera mounted on the top of the conference tablet.

[0038] Figure 3 This is a schematic diagram illustrating the position of a magnetic component according to Embodiment 1 of the present invention. Figure 3 As shown, A and B represent two permanent magnets distributed at the bottom of the target module, C and D represent two electromagnets (magnetic components) distributed at the top (upper frame) of the conference tablet, and the positions of C and D correspond to the positions of A and B respectively. E represents a distance sensor distributed at the top (upper frame) of the conference tablet, which can be used to detect the current distance between the target module and the conference tablet in real time.

[0039] S120, determine the current magnetic attraction force corresponding to the current distance based on the preset functional relationship between the target magnetic attraction force and the target distance and the current distance; wherein, the target magnetic attraction force is the magnetic attraction force between the target module and the magnetic component, and the target distance is the distance between the target module and the magnetic component.

[0040] The preset functional relationship can refer to a pre-defined functional relationship between the target magnetic attraction force and the target distance, such as a linear function or a non-linear function (such as an exponential function). The preset functional relationship can be in the form of a piecewise function, and different piecewise functions can be continuous or discontinuous (i.e., the endpoint values ​​of different piecewise functions can be the same or abruptly different). The current magnetic attraction force can refer to the magnetic attraction force between the target module and the magnetic component at the current moment.

[0041] It can be understood that when the preset functional relationship between the target magnetic attraction and the target distance and the current distance are known, by substituting the current distance into the preset functional relationship for solution, the current magnetic attraction corresponding to the current distance can be quickly and accurately determined. Since the current distance changes in real time during the process of inserting or拔出 the target module from the conference tablet, the current magnetic attraction corresponding to different current distances can be obtained according to the preset functional relationship to achieve dynamic adjustment of the magnetic attraction between the target module and the magnetic part, thereby improving the insertion and removal experience of the target module. It should be noted that when the current distance between the target module and the conference tablet is less than the preset reference distance, the current magnetic attraction can be maintained at a reasonable level so that the target module can be stably on the upper frame of the conference tablet. The preset reference distance can be set according to actual needs, and this embodiment does not limit it.

[0042] In this embodiment, optionally, the preset functional relationship between the target magnetic attraction and the target distance includes any one of the following five types:

[0043] The first type:

[0044] The second type:

[0045] The third type:

[0046] The fourth type:

[0047] The fifth type: F = M;

[0048] Among them, F represents the target magnetic attraction, L represents the target distance, M is a preset constant, M>0, N is a preset constant, N>0, and a, b, c, d, e, p, q, k are constants respectively.

[0049] Exemplarily, when p = 0, the schematic diagram of the first preset functional relationship can be seen in Figure 4A . As Figure 4A shown, in the first preset functional relationship, when the target distance satisfies 0 < L ≤ N, the target magnetic attraction remains constant at M; when the target distance satisfies L > N, the target magnetic attraction satisfies an exponential function relationship (the exponent is less than 1). When q = 0, the schematic diagram of the second preset functional relationship can be seen in Figure 4B . As Figure 4B shown, in the second preset functional relationship, when the target distance satisfies 0 < L ≤ N, the target magnetic attraction remains constant at M; when the target distance satisfies L > N, the target magnetic attraction satisfies an exponential function relationship (the exponent is greater than 1).

[0050] Exemplarily, when k = M - cN, the schematic diagram of the third preset functional relationship can be seen in Figure 4C . As Figure 4C shown, in the third preset function relationship, when the target distance satisfies 0 < L ≤ N, the target magnetic attraction remains constant at M; when the target distance satisfies L > N, the target magnetic attraction satisfies a linear function relationship. A schematic diagram of the fourth preset function relationship can be seen in Figure 4D . As Figure 4D shown, in the fourth preset function relationship, when the target distance satisfies 0 < L ≤ N and L > N respectively, the target magnetic attraction satisfies different linear function relationships. Among them, when L = 0, F = M, and when L = N, F = 0. A schematic diagram of the fifth preset function relationship can be seen in Figure 4E . As Figure 4E shown, in the fifth preset function relationship, regardless of the target distance, the target magnetic attraction always remains constant at M.

[0051] Through such a setting in this solution, by the preset function relationship between the set target magnetic attraction and the target distance, when the current distance between the target module and the conference tablet is less than the preset reference distance N, the target magnetic attraction is set to the constant M, enabling the target module to be stably on the upper frame of the conference tablet and better meeting the user's needs.

[0052] S130, control the magnetic attraction between the target module and the magnetic part to be the current magnetic attraction.

[0053] In this embodiment, after determining the current magnetic attraction corresponding to the current distance, the magnetic attraction between the target module and the magnetic part can be controlled to be the current magnetic attraction. It should be noted that there is no limitation on the control method of the magnetic attraction in this embodiment, and it can be flexibly set according to actual needs. Exemplarily, taking the magnetic part as an electromagnet, since the magnetic force of the electromagnet is affected by multiple factors such as the Gauss value of the iron core, voltage, current, and the number of turns of the coil, the magnetic attraction between the target module and the magnetic part can be controlled to be the current magnetic attraction by adjusting the value of any one or more influencing factors.

[0054] In the technical solution of the embodiment of the present invention, during the process of inserting or pulling out the target module from the conference tablet, the current distance between the target module and the conference tablet is detected in real time; according to the preset function relationship between the target magnetic attraction and the target distance and the current distance, the current magnetic attraction corresponding to the current distance is determined; where the target magnetic attraction is the magnetic attraction between the target module and the magnetic part, and the target distance is the distance between the target module and the magnetic part; control the magnetic attraction between the target module and the magnetic part to be the current magnetic attraction. This technical solution sets a magnetic part on the conference tablet, which can dynamically adjust the magnetic attraction between the module and the magnetic part according to the distance between the module and the conference tablet, making the module insertion and extraction smooth, improving the user's insertion and extraction experience, and better meeting the user's needs.

[0055] In this embodiment, optionally, determining the current magnetic attraction force corresponding to the current distance based on a preset functional relationship between the target magnetic attraction force and the target distance and the current distance includes: determining the target current corresponding to the current distance based on a preset mapping relationship between the input magnetic component current and the target distance and the current distance; wherein the mapping relationship enables the target magnetic attraction force and the target distance to satisfy a preset functional relationship; determining the current magnetic attraction force corresponding to the current distance based on the target current; controlling the magnetic attraction force between the target module and the magnetic component to be the current magnetic attraction force includes: controlling the current of the input magnetic component to be the target current, so as to control the magnetic attraction force between the target module and the magnetic component to be the current magnetic attraction force.

[0056] The target current can refer to the current corresponding to the current distance, determined based on a pre-set mapping relationship between the input magnetic component current and the target distance, and the current distance itself. This mapping relationship ensures that the target magnetic attraction force and the target distance satisfy a pre-defined functional relationship. For example, the mapping relationship can be expressed as I = f(L), where I represents the input magnetic component current and L represents the target distance.

[0057] In this embodiment, the magnetic attraction between the target module and the magnetic component can be controlled by controlling the input magnetic component current. Specifically, the current distance is first substituted into a pre-set mapping relationship between the input magnetic component current and the target distance to obtain the target current corresponding to the current distance. Since the mapping relationship ensures that the target magnetic attraction and the target distance satisfy a preset functional relationship, the current magnetic attraction corresponding to the current distance can be determined based on the target current. Then, the current of the input magnetic component is controlled to be the target current, and the magnetic attraction between the target module and the magnetic component is controlled to be the current magnetic attraction.

[0058] It should be noted that since the current distance between the target module and the conference tablet changes in real time during insertion or removal, the target current at different current distances can be obtained based on the mapping relationship. This allows for the determination of the current magnetic attraction force based on the target current at different current distances, enabling dynamic adjustment of the magnetic attraction force between the target module and the magnetic components. This improves the insertion and removal experience of the target module. When the current distance between the target module and the conference tablet is less than a preset reference distance, maintaining the current magnetic attraction force at a reasonable and stable level ensures that the target module remains stable on the conference tablet frame. The target current at this point can be defined as the stable current.

[0059] This solution, through this setting, can quickly and accurately determine the target current corresponding to the current distance based on the mapping relationship between the input magnetic component current and the target distance, as well as the current distance. This allows for dynamic adjustment of the magnetic attraction force between the target module and the magnetic component based on the target current at different current distances, ensuring smooth insertion and removal of the target module and thus improving the insertion and removal experience.

[0060] In this embodiment, optionally, before determining the target current corresponding to the current distance based on the preset mapping relationship between the input magnetic component current and the target distance and the current distance, the method further includes: determining a preset functional relationship between the target magnetic attraction force and the target distance; determining a target functional relationship between the target magnetic attraction force, the input magnetic component current, and the target distance; and determining the mapping relationship between the input magnetic component current and the target distance based on the target functional relationship and the preset functional relationship.

[0061] The target functional relationship can refer to the functional relationship between the target magnetic attraction force, the input magnetic current, and the target distance. For example, taking an electromagnet as the magnetic component, based on the characteristics of an electromagnet, the target magnetic attraction force can be expressed as F = 4B²S × 10, where F represents the target magnetic attraction force, B represents the magnetic flux density, and S represents the cross-sectional area of ​​the iron core. Since the magnetic flux density can be expressed as B = kI₀ / L, where k is a constant coefficient, I₀ represents the input electromagnet current, and L represents the target distance, the target magnetic attraction force can be further expressed as F = 4 × 2S × 10 × kI₀ / L. The formula F = 4 × 2S × 10 × kI₀ / L reflects the functional relationship between the target magnetic attraction force, the input electromagnet current, and the target distance; therefore, this formula can be defined as the target functional relationship between the target magnetic attraction force, the input electromagnet current, and the target distance.

[0062] In this embodiment, a preset functional relationship between the target magnetic attraction force and the target distance is first determined, as detailed in [reference needed]. Figures 4A-4E The system uses five preset function relationships. Then, based on the characteristics of the magnetic component, it determines the target function relationship between the target magnetic attraction force, the input magnetic component current, and the target distance. Furthermore, it determines the mapping relationship between the input magnetic component current and the target distance based on the target function relationship and the preset function relationships. For example, using... Figure 4A Taking the preset function relationship as an example, and taking F=4×2S×10×kI0 / L as the objective function relationship, the following mapping relationship can be obtained:

[0063]

[0064] This solution, through such a setting, can quickly determine the mapping relationship between the input magnetic component current and the target distance based on the objective function relationship and the preset function relationship, so that the target current corresponding to the current distance can be determined later based on the mapping relationship and the current distance.

[0065] In this embodiment, optionally, the method further includes: comparing the current distance with the previous distance; when the current distance is less than the previous distance, controlling the direction of the current input to the magnetic component to be a first direction; wherein the first direction makes the magnetic attraction between the target module and the magnetic component attractive; when the current distance is greater than the previous distance, controlling the direction of the current input to the magnetic component to be a second direction; wherein the second direction makes the magnetic attraction between the target module and the magnetic component repulsive.

[0066] Here, "previous distance" refers to the distance between the target module and the conference tablet detected at the previous detection time before the current time; that is, the distance between the target module and the conference tablet at the previous distance detection point before the current distance. "First direction" can refer to the direction of the current that makes the magnetic attraction between the target module and the magnetic component attractive. "Second direction" can refer to the direction of the current that makes the magnetic attraction between the target module and the magnetic component repulsive. It should be noted that inserting the target module into the conference tablet mainly relies on the attractive force of the magnetic component, while removing the target module from the conference tablet mainly relies on the repulsive force of the magnetic component. Specifically, the magnetic attraction or repulsive force can be controlled by adjusting the direction of the current input to the magnetic component.

[0067] In this embodiment, the current distance obtained through real-time detection is first compared with the previous distance. Then, the direction of the current input to the magnetic component is controlled based on the comparison result. By controlling the current direction, the magnetic attraction force can be controlled to be either attractive or repulsive. Specifically, when the current distance is less than the previous distance, it indicates that the target module is being inserted into the conference tablet. In this case, the direction of the current input to the magnetic component needs to be controlled in the first direction, so that the magnetic attraction force between the target module and the magnetic component is attractive. When the current distance is greater than the previous distance, it indicates that the target module is being pulled out of the conference tablet. In this case, the direction of the current input to the magnetic component needs to be controlled in the second direction, so that the magnetic attraction force between the target module and the magnetic component is repulsive. The preset functional relationship between the repulsive and attractive forces can be kept consistent, making it convenient for users to remove the target module and thus improving the user experience.

[0068] This solution, through such a setting, can determine whether the target module is being inserted into or removed from the conference tablet based on the comparison between the current distance and the previous distance. It can also adaptively adjust the current direction for different insertion and removal situations to adjust the magnetic attraction direction, making the module insertion and removal smooth and further improving the user's insertion and removal experience.

[0069] Example 2

[0070] Figure 5 This is a flowchart of a magnetic attraction control method provided in Embodiment 2 of the present invention. This embodiment is an optimization based on the above embodiment.

[0071] like Figure 5 As shown, the method in this embodiment specifically includes the following steps:

[0072] S210, during the process of inserting the target module into or removing it from the conference tablet, detects the current distance between the target module and the conference tablet in real time.

[0073] S220: Determine if the current distance is less than the preset distance threshold. If yes, execute S230-S240; otherwise, execute S250.

[0074] The preset distance threshold can refer to a pre-set distance reference value, which can be set according to actual application requirements. It should be noted that in the preset functional relationship between the target magnetic force and the target distance, if the target magnetic force and the target distance are positively correlated, then the larger the target distance, the larger the corresponding target magnetic force. However, this preset functional relationship only applies to target distances within a certain range. When the target distance is large (exceeding the applicable distance range), this preset functional relationship cannot be applied to actual module insertion and removal situations. Therefore, before determining the current magnetic force corresponding to the current distance based on the preset functional relationship between the target magnetic force and the target distance and the current distance, it is necessary to first determine whether the current distance meets the applicable distance range, i.e., whether the current distance is less than the preset distance threshold. If the current distance is less than the preset distance threshold, it means that the current distance meets the applicable range. At this time, the current magnetic attraction force corresponding to the current distance can be determined according to the preset functional relationship between the target magnetic attraction force and the target distance and the current distance, and the magnetic attraction force between the target module and the magnetic component can be controlled to be the current magnetic attraction force. If the current distance is greater than or equal to the preset distance threshold, it means that the current distance does not meet the applicable range. At this time, the current of the input magnetic component can be directly controlled to be 0, thereby reducing the calculation complexity and improving the magnetic attraction force adjustment efficiency.

[0075] S230, based on the preset functional relationship between the target magnetic attraction force and the target distance and the current distance, determine the current magnetic attraction force corresponding to the current distance; wherein, the target magnetic attraction force is the magnetic attraction force between the target module and the magnetic component, and the target distance is the distance between the target module and the magnetic component.

[0076] S240, control the magnetic attraction force between the target module and the magnetic component to the current magnetic attraction force.

[0077] The specific implementation methods of S230-S240 can be found in the detailed description of S120-S130, and will not be repeated here.

[0078] S250 controls the current of the input magnetic component to be 0.

[0079] The technical solution of this invention, before determining the current magnetic attraction force corresponding to the current distance based on the preset functional relationship between the target magnetic attraction force and the target distance and the current distance, determines whether the current distance is less than a preset distance threshold; when the current distance is less than the preset distance threshold, the current magnetic attraction force corresponding to the current distance is determined based on the preset functional relationship between the target magnetic attraction force and the target distance and the current distance; the magnetic attraction force between the target module and the magnetic component is controlled to be the current magnetic attraction force; when the current distance is greater than or equal to the preset distance threshold, the current input to the magnetic component is controlled to be 0. This technical solution, by setting a magnetic component on the conference tablet, can dynamically adjust the magnetic attraction force between the module and the magnetic component according to the distance between the module and the conference tablet, making module insertion and removal smooth and improving the user's insertion and removal experience. It also reduces computational complexity and improves the efficiency of magnetic attraction force adjustment to better meet user needs.
