Description

Technical Field

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

Background Art

[0002] Current fishing reel braking systems usually adopt braking methods such as centrifugal brakes, electromagnetic brakes, and electromagnetic brakes. Here, both the centrifugal brake and the electromagnetic brake perform brake control by mechanical structures, the brake force curve is linearized, the change process of the brake force during the casting process is difficult to change, and only manual intervention can be performed. The fishing reel braking system that adopts an electromagnetic brake rotates the line cup of the fishing reel relative to the side cover during casting, and the magnet provided on the line cup and the coil module provided on 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 rotation of the line cup. When the coil module is controlled to open, a magnetic field cannot be generated, and the rotation of the line cup is not prevented. Therefore, by inputting a fixed braking frequency and controlling 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 fishermen perform fishing reel casting with different casting postures using different bait species and different bait species ranges in different fishing scenes, the high and low rotation speeds of the line cup rise significantly. That is, the current fixed braking frequency cannot adapt to low rotation speeds and high rotation speeds. When the rotation speed of the line cup exceeds the control frequency, the response of the brake is too late and line entanglement occurs. When the rotation speed of the line cup is lower than the control frequency, the braking force is too large and the casting distance cannot be increased.

Where used in this specification and the appended claims, the singular forms "one," "one," and "the" are intended to include the plural form unless the context clearly indicates otherwise.

[0014] As used in the specification and appended claims of the present invention, the term "and / or" refers to any combination of one or more of the related enumerated items, and all possible combinations, and should be further understood to include these combinations.

[0015] Referring to FIG. 1, FIG. 1 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 in different fishing modes are constructed in advance.

[0018] In this step, different fishing modes are applied to different fishing scenes, bait types and bait type ranges, corresponding to the rotation speed of the line cup in different fishing modes, and the required braking force is also different. Therefore, corresponding braking force data can be constructed for each fishing mode. The braking force data is the current braking force information for the current rotation speed of the line cup in different fishing modes. The greater the braking force, the greater the resistance to payout for the line cup. 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 the braking forces described below can refer to the duty ratio. However, it is also possible to adopt other data indicators to characterize the braking force in other embodiments, and it is obvious that such alternatives or modifications belong to the protection scope 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, a speed detection module installed on the fishing reel detects the rotation speed of the line cup and also determines the current rotation frequency of the line cup. During casting, a magnet located on the line cup rotates with the line cup, and the speed detection module detects the rotation data of the magnet, generating a square wave periodic pulse signal for each rotation. When the square wave periodic pulse signal changes from high to low, then back to high, and then to low, interrupt 1 is triggered and counting begins by the timer. When the signal changes from low to high, interrupt 2 is triggered to complete one count. The timer statistically calculates the number of counts per second, Latest_tick_sub (ticks), and the value of the current rotation frequency Hz of the line cup can be calculated based on the formula gInputFre(Hz) = 32768 / Latest_tick_sub, where 32768 is the number of counts that can be generated per second of the clock.

[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 braking 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. Based on the braking force data corresponding to the current fishing mode, the current braking force corresponding to the current rotation frequency of the line cup can be calculated.

[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 differs in each flight stage. However, this embodiment can adaptively match the braking force based on the current rotation frequency of the line cup, and can control the rotation speed of the line cup by outputting different braking forces in each flight stage, thereby achieving accurate casting, ultra-long casting, and line tangle prevention.

[0024] In one embodiment, as shown in Figure 2, step S101 is performed as follows: S201 defines multiple different fishing modes according to one or more of the fishing scene, bait type, and bait type range, wherein the different fishing modes include at least one of the following: strong wind resistance mode, long cast mode, light bait mode, water skipping mode, pitching mode, and general-purpose mode. S202 constructs first braking force data corresponding to the rising stage of each fishing mode during casting, wherein the rising stage means that the change in the current rotation frequency of the line cup during casting is increasing. S203 constructs second braking force data corresponding to the descending stage of each fishing mode during casting, wherein the descending stage means that the change in the current rotation frequency of the line cup during casting is descending.

[0025] In this embodiment, the braking force data corresponding to different fishing modes differs. For example, comparing the strong wind resistance mode and the long-distance casting mode, the strong wind resistance mode corresponds to fishing scenes where there is wind resistance during casting. In this fishing scene, it is difficult to cast the bait far, so the line cup needs a relatively large braking force to avoid the risk of line tangling if the line cup's rotation speed is too fast, causing the line release speed to be greater than the bait's movement speed. The long-distance casting mode corresponds to fishing scenes with a tailwind during casting. In this fishing scene, the bait is cast at a faster speed due to the force of the wind, so the line cup does not need to have excessive braking force. This avoids the situation where the rotation speed and line release speed of the line cup cannot keep up with the bait's movement speed, making it impossible to cast far. In addition, the type and range of bait species also affect the bait's movement speed. For example, bait species with a large 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 multiple different fishing modes, and the user selects according to the actual situation.

[0026] In this embodiment, for each fishing mode, it is necessary to subdivide the braking force data into different flight stages during casting. Taking the ascending and descending stages as examples in this embodiment, in the ascending stage, the inertial force from the bait cast moves and rotates the line cup, causing the line to be released. In this stage, the rotational speed of the line cup 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 cast, and there is no need to increase the braking force of the line cup excessively. When casting moves from the ascending stage to the descending stage, the speed of the bait's movement decreases, and it no longer moves and rotates the line cup to release the line. At this time, the line cup can rotate at high speed due to rotational inertia, so it is necessary to increase the braking force of the line cup. This continuously reduces the change in the current rotational frequency of the line cup, preventing the line cup's rotational speed from being too fast and the line release speed from being much faster than the bait's movement speed, thereby preventing line tangling. Furthermore, in order to more accurately determine the descending stage, the condition for determining when casting reaches the descending stage from the ascending stage is that the current rotation frequency of the line cup is continuously smaller than the previous rotation frequency for a predetermined number of times, and it is preferable that the predetermined number of times is 5 (this can be custom-set according to actual requirements). For example, there are consecutive times t1, t2, t3, t4, t5, and t6 from time t1, 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, and q1>q2>q3>q4>q5>q6, and the descending stage is reached.

[0027] This embodiment introduces the flight phases using the casting data from one example shown in Figure 9 as an example. The ascent phase may include a pre-acceleration phase T1 and a sustained acceleration phase T2. The descent phase may include a high-speed feed phase T3 and a tail flight phase T4. The change in rotational speed frequency in the pre-acceleration phase T1 is ascent, with the fastest ascent change and the shortest duration. The rotational speed frequency corresponding to T1 is 0-450. The change in rotational speed frequency in the sustained acceleration phase T2 is ascent, with the ascent change gradually slowing down and the duration gradually increasing. The corresponding rotational speed frequency is 451-800, with the maximum rotational frequency (i.e., the highest point of the casting parabola) being 800. The change in rotational speed frequency in the high-speed feed phase T3 is descent, with the descent change being the fastest and the shortest duration. The corresponding rotational speed frequency is 800-500. The change in rotational speed frequency in the tail flight phase T4 is descent, with the descent change gradually slowing down and the duration gradually increasing.

[0028] Based on this, this embodiment constructs corresponding first and second braking force data based on the upward and downward 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 braking force data to using the second braking force data, and adaptively adjusts the current braking force based on the current rotational frequency of the line cup, thereby achieving precise control of the rotational speed of the line cup.

[0029] The following describes in detail how to construct the first braking force data corresponding to the upward phase of each fishing mode during casting. Note that the magnitude of the braking force in this invention can be expressed by the magnitude of the duty cycle; the larger the duty cycle, the greater the braking force. In the braking force data exemplified below, the magnitude of the braking force is expressed as a percentage of the duty cycle.

[0030] In one embodiment, as shown in Figure 3, step S202 is performed as follows: S301 constructs multiple speed stages and multiple rotation frequency ranges for each fishing mode, S302 is to set the braking force for the speed steps and the rotational frequency ranges at each stage in each fishing mode. In the speed steps of the same stage, the greater the number of stages in the rotational frequency range, the greater the braking force. In the rotational frequency range of the same stage, the greater the number of stages in the speed step, the greater the braking force. S302 includes this.

[0031] [[ID=(4]] In this embodiment, multi-stage speed steps and multi-stage rotational frequency ranges can be set in each fishing mode. The number of stages of the speed steps and the rotational frequency ranges can be set according to actual requirements. The specific range values of the rotational frequency ranges can also be set according to actual requirements. For the convenience of understanding, an example in Table 1 below is given using the first braking force data in the general mode as an example.

[0032]

Table 1

[0033] In Table 1, the speed steps in the general mode can be set to X speed steps. 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 by analogy. Thus, the magnitudes of the braking forces corresponding to the X speed steps in the rotational frequency range Q at each stage can be known. Here, A1% < B1% <...... < I1%. Based on this, within the ascending stage of casting, the rotational frequency range Q to which it belongs can be queried based on the currently collected rotational frequency of the line cup, and the corresponding current braking force can be adaptively matched in real time based on the current number of stages of the speed step.

[0034] On the other hand, in the ascending stage of each fishing mode, a minimum brake activation frequency corresponding to the ascending stage is also set. If the current rotation frequency of the line cup is smaller than the corresponding minimum brake activation frequency, the current braking force corresponding to the current rotation frequency of the line cup in each speed stage will always be 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. As can be understood, the current rotation frequency of the line cup being in the Q1-Q2 range indicates the moment when the bait is released at the start of casting. In other words, there is no need to apply braking force to the line cup to make the bait release better at the start of casting, and the bait has already been released well until the current rotation frequency of the line cup is greater than the minimum brake activation frequency. At this time, the current braking force corresponding to the current rotation frequency of the line cup is matched, and accurate control of the subsequent rotation speed of the line cup can be ensured. On the other hand, in the ascending stage of each fishing mode, a maximum brake operating frequency corresponding to each speed stage is also set. If the current rotation frequency of the line cup is equal to or greater than the corresponding maximum brake operating frequency, the maximum braking force max is used. Here, the larger the number of speed stages, the smaller the frequency range Q corresponding to the maximum brake operating frequency max. The specific values ​​of the minimum braking force min and the maximum braking force max can be set according to actual requirements.

[0035] The following describes in detail how to construct the second braking force data corresponding to the descent phase of each fishing mode during casting.

[0036] In one embodiment, as shown in Figure 4, step S203 is: S401 constructs multiple speed stages for each fishing mode, S402 sets the maximum braking force, minimum braking force, and descent coefficient for each speed stage, wherein the corresponding minimum braking force and descent coefficient increase as the number of speed stages increases. S403 includes setting the formula for calculating the current candidate braking force (which may specifically be the duty cycle) during the descent phase to the current rotational frequency of the line cup / maximum rotational frequency * current descent coefficient.

[0037] In this embodiment, in order to achieve precise control of the rotation speed of the line cup during the casting descent phase, it is necessary to adaptively match the current rotation frequency of the line cup in each fishing mode with the corresponding current braking force. Below, Table 2 is presented as an example of the second braking force data for the general-purpose mode.

[0038] [Table 2]

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

[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. At this time, there is no need to apply braking force, and the tail braking force corresponding to the case where the tail rotation frequency is W is min. When the tail rotation frequency is exactly 0, it indicates that the bait has landed in water, and this casting ends and the braking ends. Note that the max values and min values set in 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, the calculation method of the current braking force corresponding to the current rotation frequency of the line cup in the ascending stage will be specifically 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, based on the current fishing mode and current speed stage selected by the user, the current rotation frequency of the line cup is collected in real time by a speed detection module on the fishing reel during casting. 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. In 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 braking force data corresponding to the current rotation frequency of the line cup is matched, and the corresponding current braking force is output by combining it with the current speed stage set by the user. Based on this, by collecting the current rotation frequency of the line cup in the increasing stage in real time, the corresponding current braking 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] The following describes in detail how to calculate the current braking force corresponding to the current rotation frequency of a line cup in the descending phase.

[0046] In one embodiment, as shown in Figure 6, step S103 is performed as follows: S601 acquires the current fishing mode and current speed stage, S602 collects the maximum rotation frequency during casting and the current rotation frequency of the line cup in the descending phase, S603 calculates the ratio of the current rotation frequency to the maximum rotation frequency of the line cup as the current frequency ratio, and the product of the current frequency ratio and the corresponding drop coefficient is taken as the current candidate braking force. If the current candidate braking force is greater than or equal to the corresponding maximum braking force, S604 will use the maximum braking force as the current braking force, If the current candidate braking force is less than or equal to the corresponding minimum braking force, the S605 will use the minimum braking force as the current braking force. S606 includes the case where the current candidate braking force is smaller than the corresponding maximum braking force and larger than the corresponding minimum braking force, and the current candidate braking force is set to the current braking force.

[0047] In this embodiment, based on the current fishing mode and current speed stage selected by the user, the current rotation frequency of the line cup is collected in real time by a speed detection module on the fishing reel during casting. The change in the current rotation frequency of the line cup determines that the current stage is the descending stage when the continuous descent reaches a preset number of times. In the descending stage, the current rotation frequency of the line cup is collected in real time, and the current rotation frequency of the line cup is substituted into the calculation formula for the current candidate braking force in the descending stage to perform a calculation. The calculation result is output as the current candidate braking force, and further, the current candidate braking force is compared with the corresponding maximum and minimum braking forces in three cases in steps S604, S605, and S606 to confirm the final current braking force. For ease of understanding, the following example will be used for explanation. Assuming the user selects the third speed stage in general-purpose mode and performs casting, the following is obtained: The current candidate braking force is calculated as: Current rotational frequency of the line cup / Maximum rotational frequency * F3%. If the current brake force calculation result is greater than or equal to the maximum, then the current brake force is at its maximum. If the current candidate braking force calculation result is G3% or less, then the current braking force is G3%. If the current candidate braking force calculation result falls between G3% and max, then the current braking force is the current calculation result.

[0048] In a specific scenario, let W1 be the maximum rotation frequency during casting as recorded, and W2 be the current rotation frequency of the line cup during the descent phase as recorded. Thus, the current candidate braking force = W2 / W1*F3%, and let K% be the result of this calculation. 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 or equal to G3%, the current braking force is G3%. If K% is greater than or equal to max, the current braking force is max.

[0049] In one embodiment, as shown in Figure 7, the intelligent variable frequency electromagnetic brake method of the present invention is The S701 currently collects the current line-out distance during casting in fishing mode, The S702 calculates the ratio of the current distance the line cup has been extended to a preset target distance as the current distance ratio, S703, which matches the magnitude of the corresponding braking force based on the current distance ratio, further includes S703, the current distance ratio having a positive correlation with the magnitude of the braking force.

[0050] In this embodiment, a distance dataset is pre-constructed showing the corresponding line payout distance for different numbers of turns of line released from the fishing reel. During casting, a sensor assembly on the fishing reel collects the current number of turns of line released from the line cup, and calculates the current line payout distance corresponding to the current number of turns of line released based on the distance dataset. After casting, based on a preset target distance X, the braking force on the line cup is constantly increased as the current line payout distance approaches the preset target distance X, controlling the system so that the final line payout distance is as close to the target distance X as possible, thereby achieving the effect of fixed-point casting.

[0051] Specifically, the ratio of the current distance extended to a preset target distance can be calculated as the current distance ratio. As the current distance ratio increases and approaches 1, the required braking force increases. In other words, the current distance ratio has a positive correlation with the magnitude of the braking force. Thus, a set of correlations between multiple distance ratio ranges and multiple braking force magnitudes is constructed in advance, and based on the calculated current distance ratio, the distance ratio range corresponding to the current distance ratio is queried, and the magnitude of the corresponding braking force is matched. This allows for the application of the corresponding braking force in real time based on the change in the current distance ratio, achieving the effect of fixed-point casting.

[0052] Embodiments of the present invention further provide an intelligent variable frequency electromagnetic brake system, which is used to carry out any embodiment of the intelligent variable frequency electromagnetic brake method described above. Specifically, referring to Figure 8, Figure 8 is a schematic block diagram of the intelligent variable frequency electromagnetic brake system provided in an embodiment of the present invention.

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

[0054] The system can adaptively match the braking force based on the current rotation frequency of the line cup when casting in different fishing modes, and can control the rotation speed of the line cup by outputting different braking forces at different flight stages, thereby achieving accurate casting, ultra-long casts, and line tangle prevention.
