Description

[Technical Field]

[0001] The present invention relates to the field of fishing data processing technology, and more particularly to an intelligent variable frequency electromagnetic brake method, system and fishing reel. [Background technology]

[0002] Current fishing reel brake systems typically use centrifugal brakes, electromagnetic brakes, and other braking methods. Both centrifugal brakes and electromagnetic brakes use mechanical structures for brake control, resulting in a linear braking force curve. This means the braking force change process during casting is difficult to control, requiring manual intervention. In a fishing reel brake system using an electromagnetic brake, the line cup of the fishing reel rotates relative to the side cover during casting. A magnet attached to the line cup and a coil module attached to the side cover generate electromagnetic induction. When the coil module is controlled to close, a magnetic field opposite to the magnet is generated, thereby preventing the line cup from rotating. When the coil module is controlled to open, no magnetic field is generated, preventing the line cup from rotating. Therefore, by inputting a fixed braking frequency to control the opening and closing of the coil module, the magnitude of the braking force can be controlled by the duty ratio of the changed braking frequency.

[0003] However, with the development of fishing reels, when anglers use different types of bait and different ranges of bait in different fishing situations, and cast fishing reels in different casting positions, the rotation speed of the line cup varies greatly. That is, the current fixed brake frequency cannot adapt to low and high rotation speeds. When the rotation speed of the line cup exceeds the control frequency, the brake response is not fast enough, resulting in line tangles. When the rotation speed of the line cup is lower than the control frequency, the braking force is too strong and the casting distance is not long. Summary of the Invention [Problem to be solved by the invention]

[0004] The purpose of the present invention is to provide an intelligent variable frequency electromagnetic brake method, system and fishing reel to solve the problem that it is difficult to timely match the brake force control of the conventional electromagnetic brake system to the real-time rotation speed of the current line cup.

As used in the specification of the present invention and the appended claims, the singular forms "a," "one," and "the" are intended to include the plural forms unless the context clearly dictates otherwise.

[0014] It is to be further understood that the term "and / or" as used in the present specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0015] Please refer to FIG. 1, which is a schematic flowchart of an intelligent variable frequency electromagnetic braking method provided in an embodiment of the present invention.

[0016] As shown in FIG. 1, the method includes steps S101 to S103.

[0017] In S101, braking force data for different fishing modes is constructed in advance.

[0018] In this step, different fishing modes are applied to different fishing scenes, bait species, and bait species ranges, and correspond to different line cup rotation speeds and required braking forces. Therefore, corresponding braking force data can be established for each fishing mode. The braking force data is current braking force information for the current line cup rotation speed in different fishing modes. The greater the braking force, the greater the line cup's payout resistance. Note that the braking force can be characterized in different ways. In this embodiment, it can be characterized by the duty ratio. The greater the duty ratio, the greater the braking force. All braking forces described below can refer to the duty ratio. However, other data indicators can be used to characterize the braking force in other embodiments, and such substitutions or modifications are obviously within the scope of protection of the present application.

[0019] In S102, the current rotation frequency of the line cup of the fishing reel when casting in the current fishing mode is collected.

[0020] In this step, the speed detection module installed in the fishing reel detects the rotation speed of the line cup, and can also determine the current rotation frequency of the line cup. When casting, the magnet located in the line cup rotates along with the line cup. The speed detection module detects the rotation data of the magnet and generates a square wave periodic pulse signal for each rotation. When the square wave periodic pulse signal changes from high to low, then changes to high, and then changes to low, interrupt 1 is triggered to start counting by the timer. When the signal changes from low to high, interrupt 2 is triggered to complete one count. The timer counts the number of counts counted per second, Latest_tick_sub (tick), and can calculate the current rotation frequency Hz of the line cup according to the formula gInputFre(Hz)=32768 / Latest_tick_sub, where 32768 is the 32768 counts that the clock can generate per second.

[0021] In S103, the current braking force corresponding to the current rotation frequency of the line cup is calculated based on the braking force data corresponding to the current fishing mode.

[0022] In this step, the corresponding brake force data is obtained based on the fishing mode currently selected by the user (i.e., the current fishing mode), and then the current rotation frequency of the line cup is obtained based on the method of step S102, and the current brake force corresponding to the current rotation frequency of the line cup can be calculated based on the brake force data corresponding to the current fishing mode.

[0023] In this embodiment, when casting in different fishing modes, there are different flight stages (i.e., ascending and descending stages) for each cast, and the current rotation frequency of the line cup is different in different flight stages. However, this embodiment can adaptively match the corresponding braking force based on the current rotation frequency of the line cup, and output different braking forces in different flight stages to control the rotation speed of the line cup, thereby achieving the effects of accurate casting, ultra-long distance casting, and preventing line tangles.

[0024] In one embodiment, as shown in FIG. 2, step S101 includes: S201 defining a plurality of different fishing modes according to one or more of a fishing scene, a type of bait species, and a range of bait species, wherein the different fishing modes include at least one of a strong wind resistance mode, a long-distance casting mode, a light bait mode, a water-spinning mode, a pitching mode, and a general-purpose mode; S202 constructing first braking force data corresponding to an increasing stage of each fishing mode during casting, where the increasing stage means that the change in the current rotation frequency of the line cup during casting is increasing; S203 of constructing second braking force data corresponding to the descending stage of each fishing mode during casting, where the descending stage means that the change in the current rotation frequency of the line cup during casting is descending.

[0025] In this embodiment, different braking force data correspond to different fishing modes. For example, comparing the high wind resistance mode and the long-distance casting mode, the high wind resistance mode corresponds to fishing situations where there is wind resistance during casting, making it difficult to cast the bait far. Therefore, a relatively large braking force is required for the line cup to avoid the line cup rotating too fast and reeling out faster than the bait's movement speed, which could result in line tangles. The long-distance casting mode corresponds to fishing situations where there is a tailwind during casting, where the bait is cast at a faster speed due to the wind's force. Therefore, the line cup must not have excessive braking force to avoid the line cup's rotational speed not being able to keep up with the bait's movement speed, making it difficult to cast far. Furthermore, different types and ranges of bait species also affect the bait's movement speed. For example, bait species with a high gram weight and low wind resistance are suitable for the long-distance casting mode. Based on this, this embodiment sets multiple braking force data corresponding to different fishing modes, allowing the user to select one according to the actual situation.

[0026] In this embodiment, for each fishing mode, different braking force data must be subdivided into different flight stages during casting. Take the ascending and descending stages as examples. In the ascending stage, the inertial force generated by the casting of the bait causes the line cup to rotate and be released. The rotational speed of the line cup during this stage follows the casting speed of the bait. Therefore, in the ascending stage, the change in the current rotational frequency of the line cup increases until it reaches the maximum rotational frequency of the current casting. Therefore, there is no need to increase the braking force on the line cup excessively. When the casting shifts from the ascending stage to the descending stage, the movement speed of the bait decreases and the line cup is no longer moved, rotated, and released. At this time, the line cup can rotate at high speed due to rotational inertia. Therefore, it is necessary to increase the braking force on the line cup, and the change in the current rotational frequency of the line cup is continuously reduced. This prevents the line cup from rotating too fast, causing the reeling speed to be much faster than the movement speed of the bait, thereby preventing line tangles. In order to more accurately determine the descending stage, the condition for determining whether casting has reached the descending stage from the ascending stage is that the current rotation frequency of the line cup is lower than the previous rotation frequency a predetermined number of times in succession, preferably five times (this can be customized according to actual requirements). For example, given successive times t1, t2, t3, t4, t5, and t6, the current rotation frequency of the line cup at time t1 is q1, the current rotation frequency of the line cup at time t2 is q2, the current rotation frequency of the line cup at time t3 is q3, the current rotation frequency of the line cup at time t4 is q4, the current rotation frequency of the line cup at time t5 is q5, and the current rotation frequency of the line cup at time t6 is q6, where q1>q2>q3>q4>q5>q6, and the descending stage is reached.

[0027] In this embodiment, the flight stages are introduced using the example data of one casting shown in Figure 9 as an example. The ascending stage may include a pre-acceleration stage T1 and a sustained acceleration stage T2, and the descending stage may include a high-speed payout stage T3 and a tail flight stage T4. The change in rotation speed frequency of the pre-acceleration stage T1 is ascending, the ascending change is the fastest and the time taken is the shortest, and the rotation speed frequency corresponding to T1 is 0 to 450. The change in rotation speed frequency of the sustained acceleration stage T2 is ascending, the ascending change gradually slows and the time taken is gradually longer, and the corresponding rotation speed frequency is 451 to 800, and the maximum rotation frequency (i.e., the highest point of the casting parabola) is 800. The change in rotation speed frequency of the high-speed payout stage T3 is descending, the descending change is the fastest and the time taken is the shortest, and the corresponding rotation speed frequency is 800 to 500. The change in rotation speed frequency of the tail flight stage T4 is descending, the descending change gradually slows and the time taken is gradually longer.

[0028] Based on this, this embodiment constructs corresponding first and second brake force data based on the ascending and descending phases, respectively. When the system recognizes a decrease in the rotational speed of the line cup, the system automatically and adaptively switches from using the first brake force data to using the second brake force data, and adaptively and variably adjusts the current brake force based on the current rotational frequency of the line cup, thereby achieving accurate control of the rotational speed of the line cup.

[0029] The following is a detailed description of how to create the first braking force data corresponding to the increasing stages of each fishing mode during casting. Note that the magnitude of the braking force in this application can be expressed as the magnitude of the duty ratio, and the larger the duty ratio, the greater the braking force. The magnitude of the braking force in the braking force data exemplified below is all expressed as a percentage of the duty ratio.

[0030] In one embodiment, as shown in FIG. 3, step S202 includes: S301 for constructing multiple speed stages and multiple rotation frequency ranges in each fishing mode; S302 sets the braking force for each speed level and the rotational frequency range at each stage in each fishing mode. In the same speed level, the greater the number of stages in the rotational frequency range, the greater the braking force. In the same rotational frequency range, the greater the number of stages in the speed level, the greater the braking force. S302 includes this.

[0031] In this embodiment, multi-level speed levels and multi-level rotational frequency ranges can be set in each fishing mode. The number of levels of the speed level and the rotational frequency range can be set according to actual requirements. The specific range values of the rotational frequency range can also be set according to actual requirements. For the convenience of understanding, an example in Table 1 below will be given using the first braking force data in the general mode as an example.

[0032]

Table 1

[0033] In Table 1, the speed level in the general mode can be set to X speed levels. Q1 is the rotational frequency range with the minimum number of stages, Qi is the rotational frequency range with the maximum number of stages. min represents the minimum braking force, max represents the maximum braking force. Q1 to Qi increase linearly with the preset amplification of the rotational frequency. A1% to Aa% increase linearly with the preset amplification. B1% to Bb% increase linearly with the preset amplification,... and so on. In this way, it is possible to know the magnitude of the braking force corresponding to each of the X speed levels in the rotational frequency range Q at each stage. Here, A1% < B1% <...... < I1%. Based on this, within the ascending stage of casting, it is possible to query the rotational frequency range Q to which it belongs based on the current rotational frequency of the collected line cup, and adaptively match the corresponding current braking force in real time based on the current number of speed levels.

[0034] In addition, a minimum brake activation frequency is also set for the ascending stage of each fishing mode. When the current rotation frequency of the line cup is lower than the corresponding minimum brake activation frequency, the current brake force corresponding to the current rotation frequency of the line cup at each speed stage is the minimum brake force min. For example, the minimum brake activation frequency in Table 1 is the maximum frequency value in the rotation frequency range Q2. Any current rotation frequency of the line cup that is lower than the maximum frequency value in the rotation frequency range Q2 is the minimum brake force min. It can be understood that the current rotation frequency of the line cup in the Q1-Q2 range refers to the moment when the bait pops out at the start of casting. That is, to make the bait pop out better at the start of casting, there is no need to apply brake force to the line cup. When the current rotation frequency of the line cup is higher than the minimum brake activation frequency, the bait has already been popped out well. At this time, the corresponding current brake force is adjusted based on the current rotation frequency of the line cup to ensure accurate control of the subsequent rotation speed of the line cup. On the other hand, in the ascending stage of each fishing mode, the maximum braking frequency corresponding to each speed stage is also set, and when the current rotation frequency of the line cup is equal to or higher than the corresponding maximum braking frequency, the maximum braking force max is adopted, where the larger the speed stage number, the smaller the frequency range Q corresponding to the maximum braking frequency max. Note that the specific values ​​of the minimum braking force min and the maximum braking force max can be set according to actual requirements.

[0035] The construction of the second braking force data corresponding to the descending stage of each fishing mode during casting will be specifically introduced below.

[0036] In one embodiment, as shown in FIG. 4, step S203 includes: The S401 builds multiple speed stages for each fishing mode, S402 sets a maximum brake force, a minimum brake force, and a decrease coefficient for each speed stage, where the larger the speed stage number, the larger the corresponding minimum brake force and decrease coefficient; and S403 of setting the calculation formula for the current candidate brake force (specifically, it may be a duty ratio) in the descending stage to the current rotation frequency of the line cup / maximum rotation frequency*current descending coefficient.

[0037] In this embodiment, in order to accurately control the rotation speed of the line cup during the descending phase of casting, the current rotation frequency of the line cup in each fishing mode also needs to be adaptively matched with the corresponding current braking force. Below, we will continue to introduce the second braking force data of the general mode as an example, as shown in Table 2 below.

[0038] [Table 2]

[0039] In Table 2, the speed stages in the general-purpose mode are set to X speed stages, and the number of speed stages for the ascending and descending stages in each fishing mode may be the same or different, although it is preferable to use the same number of speed stages here. In multiple fishing modes, the number of speed stages used in each fishing mode may be the same or different, although it is preferable to use the same number of speed stages here. In addition, the maximum braking force at each speed stage can be made the same.

[0040] In Table 2, in the descending stage in the general mode, the maximum braking force and the minimum braking force corresponding to the speed stages by level are set. Here, G1% < G2% < G3% < …… < max, and the descending coefficients F1% to Ff% increase linearly with a preset amplification. When the tail rotation frequency is W, the line cup almost stops rotating, that is, the bait has almost finished flying, and at this time, there is no need to apply braking force. The tail braking force corresponding to the case where the tail rotation frequency is W is min. When the tail rotation frequency is completely 0, it indicates that the bait has landed on the water, and this casting is completed and the braking ends. Note that the max values and min values set for the descending stage and the ascending stage may be the same or different, and specifically, they may be set according to actual requirements.

[0041] Based on the parameters limited in Table 2, calculate using the calculation formula of the current candidate braking force in the descending stage to obtain a calculation result, and obtain the calculation result within the range between the maximum braking force and the minimum braking force, thereby obtaining the current braking force.

[0042] Hereinafter, a specific method for calculating the current braking force corresponding to the current rotation frequency of the line cup in the ascending stage will be introduced.

[0043] In one embodiment, as shown in FIG. 5, step S103 includes: S501 for obtaining the current fishing mode and the current speed stage; S502 for collecting the current rotation frequency of the line cup in the ascending stage during casting; S503 for matching the current rotation frequency range of the corresponding line cup in the corresponding first braking force data based on the current rotation frequency of the line cup; S504 for obtaining the corresponding braking force based on the current rotation frequency range of the line cup and the current speed stage and setting it as the current braking force.

[0044] In this embodiment, the speed detection module on the fishing reel collects the current rotation frequency of the line cup in real time during casting based on the current fishing mode and current speed stage selected by the user. If the change in the current rotation frequency of the line cup is increasing, it is determined that the current stage is the increasing stage. During the increasing stage, the current rotation frequency of the line cup is collected in real time, and the current rotation frequency range of the line cup located in the first brake force data corresponding to the current rotation frequency of the line cup is matched with the current speed stage set by the user to output the corresponding current brake force. Based on this, by collecting the current rotation frequency of the line cup in real time during the increasing stage, the corresponding current brake force can be adaptively matched each time the current rotation frequency of the line cup switches to a different rotation frequency range and a different speed stage, thereby achieving accurate control of the rotation speed of the line cup.

[0045] Below, we will specifically introduce how to calculate the current braking force corresponding to the current rotation frequency of the line cup in the descending stage.

[0046] In one embodiment, as shown in FIG. 6, step S103 includes: S601 acquires the current fishing mode and the current speed stage; S602: collecting the maximum rotation frequency during casting and the current rotation frequency of the line cup in the descending stage; S603: calculating a ratio between the current rotation frequency of the line cup and the maximum rotation frequency as a current frequency ratio, and calculating a product of the current frequency ratio and a corresponding reduction coefficient as a current candidate braking force; If the current candidate braking force is equal to or greater than the corresponding maximum braking force, the maximum braking force is set as the current braking force in step S604; S605: if the current candidate braking force is equal to or less than the corresponding minimum braking force, the minimum braking force is set as the current braking force; If the current candidate braking force is smaller than the corresponding maximum braking force and larger than the corresponding minimum braking force, the current candidate braking force is set as the current braking force in step S606.

[0047] In this embodiment, based on the current fishing mode and current speed selected by the user, the speed detection module on the fishing reel collects the current rotation frequency of the line cup in real time during casting. The current phase is determined to be the down phase when the current rotation frequency of the line cup reaches a preset number of consecutive downswings. During the down phase, the current rotation frequency of the line cup is collected in real time and substituted into a formula for calculating the current candidate braking force for the down phase. The calculation result is output as the current candidate braking force. Furthermore, the current candidate braking force is compared with the corresponding maximum and minimum braking forces in steps S604, S605, and S606, and the final current braking force is determined. For ease of understanding, the following example is used: Assuming the user selects the third speed in general mode and casts, the following is obtained: Current candidate brake force = current rotation frequency of line cup / maximum rotation frequency * F3% If the calculation result of the current candidate brake force is greater than or equal to max, the current brake force is max. If the calculation result of the current candidate brake force is G3% or less, the current brake force is G3%. If the calculation result of the current candidate brake force is between G3% and max, the current brake force is the current calculation result.

[0048] In a specific scenario, the collected maximum rotation frequency during casting is W1, and the collected current rotation frequency of the line cup during the descending stage is W2, that is, the current candidate braking force = W2 / W1*F3%, and the calculation result is K%, and if K% is between G3% and max, the current braking force corresponding to the current rotation frequency W2 of the line cup is K%, if K% is less than G3%, the current braking force is G3%, and if K% is greater than max, the current braking force is max.

[0049] In one embodiment, as shown in FIG. 7, the intelligent variable frequency electromagnetic braking method of the present invention includes: The S701 collects the current payout distance of the line cup when casting in fishing mode, and S702: calculating a ratio of a current payout distance of the line cup to a preset target distance as a current distance ratio; The method further includes: S703 matching the magnitude of the corresponding braking force based on a current distance ratio, where the current distance ratio has a positive correlation with the magnitude of the braking force.

[0050] In this embodiment, a distance data set of the corresponding payout distances for different payout windings of the fishing reel is established in advance, and the current payout windings of the line cup are collected by a sensor assembly installed on the fishing reel during casting, and the current payout distance corresponding to the current payout windings is calculated based on the distance data set. After casting, based on the preset target distance X, the braking force on the line cup is continuously increased as the current payout distance approaches the preset target distance X, so as to control the final payout distance to be as close as possible to the target distance X, thereby achieving the effect of fixed-point casting.

[0051] Specifically, the ratio of the current payout distance to the preset target distance can be calculated as the current distance ratio, and the closer the current distance ratio is to 1, the greater the required braking force; that is, the current distance ratio has a positive correlation with the magnitude of the braking force. In this way, a correlation set between multiple distance ratio ranges and multiple braking force magnitudes is pre-established, and when the distance ratio range corresponding to the current distance ratio is inquired based on the calculated current distance ratio, the corresponding braking force magnitude is matched, and thereby the corresponding braking force is applied in real time based on changes in the current distance ratio, thereby achieving the effect of fixed-point casting.

[0052] The present invention further provides an intelligent variable frequency electromagnetic brake system, which can be used to implement any of the above-described intelligent variable frequency electromagnetic brake methods. Specifically, refer to Figure 8, which is a schematic block diagram of the intelligent variable frequency electromagnetic brake system provided in the present invention.

[0053] As shown in FIG. 8, the intelligent variable frequency electromagnetic brake system 800 includes: A construction unit 801 for pre-constructing braking force data under different fishing modes; a collecting unit 802 for collecting a current rotation frequency of a line cup of the fishing reel when casting in a current fishing mode; and a calculation unit 803 for calculating a current brake force corresponding to a current rotation frequency of the line cup based on the brake force data corresponding to a current fishing mode.

[0054] When casting in different fishing modes, the system can adaptively match the corresponding braking force according to the current rotation frequency of the line cup, and output different braking forces at different flight stages to control the rotation speed of the line cup, thereby achieving the effects of accurate casting, ultra-long casting distance and anti-tangle.

[0055] An embodiment of the present invention further provides a fishing reel including the above-described intelligent variable frequency electromagnetic brake system.

[0056] Those skilled in the art will understand that for convenience and brevity of explanation, the specific operation processes of the above-described systems and units may refer to the corresponding processes in the above-described method embodiments, and the description thereof will be omitted here.

Those skilled in the art can easily imagine various equivalent modifications and replacements within the technical scope of the present invention, and these modifications and replacements are included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined only by the scope of protection of the claims.
