Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of intelligent control of electric fishing gear, and particularly provides a fishing line winding and unwinding comprehensive control system. BACKGROUND

[0002] A fishing rod line cup (also known as a line reel, a line winding drum, etc.) is used to wind and align fishing lines, and is an important component of a fishing rod. More and more fishing rods have been installed with electric line cups. The electric line cup uses the principle of electromagnetic induction to brake the line cup in the second half of the line throwing process, which can better solve the problem of line explosion caused by the speed of the line cup exceeding the speed of the forward movement of the hook when the manual line cup throws the line.

[0003] Although the above-mentioned electric line cup with braking can effectively solve the problem of line explosion caused by the recoil of the line cup, in the first half of the rod throwing process, the inertia of the line cup itself causes it to generate a drag force on the fishing line in the opposite direction of the line throwing direction. At this time, if the line cup cannot be accelerated quickly, the drag force will significantly consume the kinetic energy of the forward movement of the hook, thereby causing the final line throwing distance to be shortened. Meanwhile, during the forward movement of the hook, when the speed of the line cup is consistent with the forward speed of the hook, if the movement state of the electric line cup can be avoided as much as possible, the duration of the speed matching of the two can be as long as possible.

[0004] Therefore, a system capable of more finely controlling the acceleration and braking of the electric line cup in different movement states during the entire rod throwing process is needed. SUMMARY

[0032] The present application is further described below based on preferred embodiments and with reference to the accompanying drawings.

[0033] In addition, for the convenience of understanding, various components on the drawings are enlarged or reduced, but such practice is not intended to limit the protection scope of the present application. In addition, in the description of the present application, the first, second, etc. are used on the specification to distinguish different units, but these will not be limited by the order of manufacture, nor can they be understood as indicating or implying relative importance, and the names thereof may be different in the detailed description and the claims of the present application.

[0034] The vocabulary used in this specification is for illustrative purposes and is not intended to limit the scope of this application. It should also be noted that, unless otherwise expressly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection via an intermediate medium; or they can refer to the internal communication between two components. Those skilled in the art will understand the specific meaning of these terms in this application.

[0035] This application provides a comprehensive control system for reeling in and releasing fishing lines through embodiments. This system can comprehensively control the actions of an electric spool mounted on a fishing rod during the reeling in and releasing process. Figure 1 As shown, the system includes a main control unit, a first control unit, a second control unit, and an energy storage unit. The first control unit is located between the energy storage unit and the terminal block of the drive circuit of the electric spool and is electrically connected to the terminal blocks of both the energy storage unit and the drive circuit. The second control unit is located between the energy storage unit and the grounding terminal and is electrically connected to both the energy storage unit and the grounding terminal.

[0036] Figure 2 This is a schematic diagram of the appearance of the electric spool controlled by the integrated fishing line reel-in and reel-out control system provided in the embodiments of this application, as shown below. Figure 2 As shown, the electric spool includes a frame 10 that is fixed relative to the fishing rod, and a spool 20 housed within the frame 10. The spool 20 is rotatably connected to the frame 10, and its outer circumferential surface is used for winding fishing line. In addition, the electric spool also includes a handle 30 that can manually rotate the spool 20 in the forward (i.e., letting out line) or reverse (i.e., reeling in line) direction. The handle 30 can be rotated at a specific speed ratio with the spool 20 through a set of mutually cooperating gears. The above structure and its operation are well known to those skilled in the art and will not be described in detail here.

[0037] Specifically, the spool 20 is coaxially equipped with a magnetic core composed of permanent magnets and a coil assembly composed of multiple sets of electromagnetic coils (not shown in the figure), as well as a drive circuit electrically connected to the coil assembly. One of the magnetic cores or coil assemblies (e.g., the magnetic core) acts as the stator, fixed relative to the frame, while the other (e.g., the coil assembly) acts as the rotor, fixedly connected to the inner wall of the spool 20. When the spool 20 rotates relative to the frame 10, the electromagnetic coils generate an induced current by cutting the magnetic field produced by the magnetic core. At this time, the stator-rotor assembly acts as a generator, converting rotational kinetic energy into electrical energy and outputting it through the terminals of the drive circuit, thereby producing a braking effect. When the electromagnetic coils receive external current from the terminals of the drive circuit, the rotor drives the spool to rotate through electromagnetic induction. At this time, the stator-rotor assembly acts as a motor, converting the externally input electrical energy into the rotational kinetic energy of the spool.

[0038] Figure 3 The schematic diagram of a driving circuit of an electric line cup is shown as Figure 3 The main body of the driving circuit is composed of a three-phase bridge rectifier circuit, which is electrically connected with three groups of electromagnetic coils through U, V and W terminals. The current direction of each rectifier circuit is controlled by the on-off state of two MOS tubes (M1 and M4 terminals are used to control the U circuit, M2 and M4 terminals are used to control the V circuit, and M3 and M6 terminals are used to control the W circuit). Generally, whether the stator-rotor combination is in a power generation state or a power consumption state depends on the comparison result of the external voltage connected to the terminal (i.e. FA terminal in the figure) of the driving circuit and the induced voltage generated by the coil cutting magnetic field. The above stator-rotor and its driving circuit technology is known to those skilled in the art, and will not be described here.

[0039] Specifically, in the embodiments of the present application, the main control unit switches the energy storage unit between the discharge mode, the charging mode and the non-working mode of the driving circuit according to the state of the electric line cup in the process of fishing line releasing and winding, which will be described in detail below in combination with the drawings.

[0040] As shown in the main control unit circuit schematic diagram Figure 4 In some embodiments of the present application, the main control unit U1 selects a super low power Arm Cortex-M0+ MCU with a model number of STM32L051K8. The chip has a 64-KB Flash memory and a 32MHz CPU, a power consumption of 2.7mW, and a sleep mode of as low as 4.5uA and a stop mode of 0.4uA. In other optional embodiments, the main control unit can also select a suitable model of MCU chip according to the size of the line cup frame and the demand for data processing.

[0041] The chip has a supply voltage of 3.3V. The IO-IN-06 port outputs a first control signal to the first control unit; the IO-IN-05 port outputs a second control signal to the second control unit; and the M1 to M6 ports are connected to the M1 to M6 ports of the driving circuit in Figure 3 for outputting a rotation speed control signal to the driving circuit (the rotation speed control signal can be a PWM signal sent by the M1 to M6 ports in different orders and duty cycles, which controls the on-off of each electromagnetic coil through the M1 to M6 ports of the driving circuit, thereby realizing the control of the rotation speed of the line cup); by using the above first control signal, second control signal and rotation speed control signal, the main control unit can finely control the acceleration, braking control or free motion state of the line cup in the whole process of rod throwing and line throwing, and control the size of the acceleration force and braking force in the acceleration and braking process.

[0042] 1) Discharge mode

[0043] Figure 5 A schematic diagram showing the relative state change between the fishhook and the line cup during the rod throwing and line throwing process under an existing control strategy is shown. The control unit of the existing electric line cup generally monitors the tension of the fishing line (which can be obtained by the acceleration of the line cup rotation) or the rotation speed of the line cup in real time, and determines whether to enter the line cup recoil stage and the fishhook water entry stage according to a preset algorithm. In the above line cup recoil stage, the speed of the fishhook driving the fishing line forward has gradually decreased from the maximum speed, and in the fishhook water entry stage, the speed decreases sharply until the fishhook enters the water, at which time the forward speed will decrease sharply. In this process, since the rotational inertia of the line cup is much larger than the momentum of the fishhook and the fishing line, the speed decrease trend is much smaller than the deceleration of the fishhook and the fishing line. If the deceleration is not controlled, the fishing line will be wound and accumulated on the outer wall of the line cup, that is, the "line explosion" phenomenon will occur.

[0044] Braking the line cup during the above line cup recoil stage and fishhook water entry stage can be achieved by controlling the on-off state of multiple electromagnetic coils. At this time, the stator-rotor combination will act as a generator, converting the kinetic energy of the line cup rotation into electrical energy, thereby achieving the braking effect of the line cup. Further, by adjusting the beat and duty cycle of the rotation speed control signal delivered by the control unit to the drive circuit, the control of the braking force can be achieved.

[0045] The above braking of the line cup can effectively reduce the occurrence of the "line explosion" phenomenon. However, the factors affecting the entire line throwing effect do not only appear in the second half of the rod throwing and line throwing process. For example, Figure 5 As shown in the fish line dragging stage at the beginning of the rod throwing and line throwing, since the fishhook needs to drive the line cup to gradually accelerate, a large part of the kinetic energy of the fishhook when it is thrown out is consumed in dragging the line cup, which will cause great loss to the energy of the forward throwing of the fishhook, thereby greatly shortening the final water entry point distance of the fishhook.

[0046] Obviously, if an additional driving force is provided for the line cup in the initial fish line dragging stage of the rod throwing, the above additional driving force can significantly reduce the dragging force of the fishing line required for the acceleration of the line cup, thereby increasing the rotation speed of the line cup as soon as possible under the premise of consuming as little forward kinetic energy of the fishhook as possible to enter the matching stage. At this time, since most of the kinetic energy of the fishhook is not consumed in driving the line cup, accordingly, the forward speed of the fishhook is much higher than the case where no additional driving force is provided, that is, the speed of the line cup and the fishhook entering the matching state is greatly improved, and the time length of the line cup and the fishhook and the fishing line remaining in the matching state is greatly prolonged, thereby effectively increasing the water entry distance of the fishhook.

[0047] In the embodiments of the present application, the above-mentioned additional driving force provided to the electric line cup in the fish line dragging stage is achieved by controlling the first control unit and the second control unit, so that the energy storage unit is in the discharging mode. Specifically, as shown in Figure 2 and Figure 4 , the main control unit sends a first control signal to the first control unit and a second control signal to the second control unit, respectively. The second control unit is turned on under the control of the second control signal, and at the same time, the first control unit has a one-way current path from the energy storage unit to the terminal under the control of the first control signal. At this time, the energy storage unit is in the discharging mode.

[0048] The energy storage unit can be composed of a large-capacity charge-discharge capacitor. When the voltage of the energy storage unit is higher than the voltage at the terminal, it can discharge to the driving circuit. At this time, the stator-rotor combination will act as a motor, converting the kinetic energy of the line cup rotation into electrical energy, thereby achieving the acceleration effect of the line cup.

[0049] Further, as shown in Figure 1 , Figure 3 and Figure 4 , the main control unit also sends a PWM signal as a rotation speed control signal to the M1 to M6 ends of the driving circuit through the M1 to M6 ports, respectively, thereby achieving control of the rotation speed of the line cup.

[0050] 2) Charging mode

[0051] When the rod-throwing line enters the line cup recoil stage, the rotation speed of the line cup has exceeded the forward speed of the fish hook. At this time, the main control unit switches the first control signal so that the first control unit has a one-way current path from the terminal to the energy storage unit, and the second control signal is the same as in the discharging mode. At this time, the energy storage unit enters the charging mode. When the voltage at the terminal is higher than the voltage of the energy storage unit, the energy storage unit can be charged by the driving circuit. At this time, the stator-rotor combination will act as a motor, converting the kinetic energy of the line cup rotation into electrical energy, thereby achieving the braking effect of the line cup.

[0052] Further, as shown in Figure 1 , Figure 3 and Figure 4 , the main control unit also sends a PWM signal as a rotation speed control signal to the M1 to M6 ends of the driving circuit through the M1 to M6 ports, respectively, thereby achieving control of the rotation speed of the line cup.

[0053] 3) Non-working mode

[0054] When the energy storage unit is in the discharging mode and the charging mode, since the current path is maintained in at least one direction between the terminal and the energy storage unit, as long as the voltage between the energy storage unit and the terminal meets the requirement of discharging or charging, the effect of acceleration or braking on the cup is generated. However, through the analysis of the speed and force between the cup and the fishing line during the process of throwing the rod and the line, it is found that, in the middle of the process of throwing the rod and the line, when the rotating speed of the cup matches the forward speed of the hook, the fishing line remains a certain slack and does not wind, at this time, the hook and the cup do not affect each other in the relative speed, at this time, if the energy storage unit is in the discharging mode or the charging mode, unnecessary acceleration or braking of the cup may be generated, thereby causing the early end of the free motion state, therefore, it is necessary to close the current path between the energy storage unit and the driving circuit at this stage, so that the cup is not controlled by any external driving force, and the speed of the cup gradually decreases under the action of the friction force of the cup itself.

[0055] Therefore, in the embodiment of the present application, the energy storage unit can also be in a non-working mode, specifically, when the energy storage unit is in the non-working mode, the main control unit switches the second control signal sent to the second control unit, so that the second control unit is open at this time, the energy storage unit neither discharges to the driving circuit nor charges from the driving circuit.

[0056] Figure 6 The schematic diagram of the relative state change between the hook and the cup of the electric cup controlled by the winding and unwinding comprehensive control system using the embodiment of the present application during the process of throwing the rod and the line is shown as follows, Figure 6 Compared with the existing cup control mode, the winding and unwinding control system provided by the present application is more conducive to the increase of the throwing time and the throwing distance.

[0057] In the initial fishing line dragging stage of the rod, the energy storage unit discharges to the driving circuit to provide additional driving force for the cup, which can greatly weaken the dragging force of the cup on the hook, thereby effectively reducing the consumption of the forward kinetic energy of the hook, which can quickly increase the rotating speed of the cup to enter the matching stage, and can greatly increase the speed of the cup and the hook when they enter the matching state.

[0058] After the speed of the two reaches the matching state, the energy storage unit enters the non-working mode, at this time, the cup is not affected by the external driving force or the braking force, thereby avoiding unnecessary external interference, so that the time length of the matching state of the cup and the hook and the fishing line is greatly prolonged, and the throwing distance is effectively increased.

[0059] Finally, in the late stage of throwing the rod and the line, the braking of the cup is used to charge the energy storage unit again, thereby realizing the recovery of electric energy and storing energy for the acceleration of the cup in the initial stage of the next time of throwing the line.

[0060] The timing of switching the first control signal and the second control signal by the main control unit, and the setting of the beat and duty cycle of the output rotational speed control signal, depend on the judgment of the relationship between the rotational speed and the force between the line cup and the fish hook during the whole rod casting process. In the embodiments of the present application, the main control unit can send the first control signal and the second control signal to the first control unit and the second control unit respectively according to at least one of the following information: a level trigger signal, a speed signal, an acceleration signal, a posture signal, and a voltage at the terminal.

[0061] For example, in some embodiments of the present application, the rotational speed signal of the line cup can be obtained by a counter arranged in the frame of the electric line cup, or by detecting the frequency of the on-off of the electromagnetic coil through a detection circuit connected to the electromagnetic coil, and then obtaining the rotational speed signal of the line cup; for another example, by calculating the rate of change of the rotational speed, the signal of the rotational acceleration of the line cup can be obtained. Obviously, the rotational acceleration can be further converted into the torque of the line cup and the corresponding fishing line tension and other information; for another example, the posture signal of the electric line cup or the fishing rod can be obtained by arranging an accelerometer or the like at a specific position of the electric line cup or the fishing rod; in addition, the level trigger signal can also be obtained by using a combination of mechanical structure and circuit, for example, an automatic pop-up mode switching button and a circuit matched therewith can be arranged on the frame of the electric line cup. When the user presses the mode switching button, the circuit is triggered and outputs a high level signal (or a low level signal) to the main control unit. When the user removes his finger, the mode switching button automatically pops up, and the circuit outputs a low level signal (or a high level signal) to the main control unit.

[0062] Further, it is found that the induced electromotive force generated by the rotation of the line cup during the rod casting and line winding process varies between 0V and 10V, and the high and low of the induced electromotive force shows strong correlation with the rotational speed of the line cup. Therefore, in some preferred embodiments, the stage of the rod casting can also be judged by the high and low of the voltage at the terminal to determine the timing of mode switching.

[0063] The above signals can be directly input into the main control unit through various IO ports, such as IO-IN-01 port to IO-IN-04 port, and the like, as shown in Figure 4 In addition, in some preferred embodiments, the signals can also be input into the main control unit through the IO ports and the corresponding detection circuits, as shown in Figure 7As shown, the above various information is uniformly output to the master control unit by a special monitoring unit. After receiving the above various signals, the master control unit evaluates the current stage of the rod throwing and line throwing by a pre-set evaluation program, and outputs corresponding first mode signal, second mode signal and speed control signal, wherein the speed control signal can be a PWM signal as described above, and the first mode signal and the second mode signal can be high-low level signals, which respectively switch the current flow direction in the first control unit and the on-off of the second control unit by switching the level high or low.

[0064] Specifically, in some preferred embodiments of the present application, the monitoring unit can combine the voltage signal at the terminal with the aforementioned speed signal, acceleration signal, etc.: in the line dragging stage, the energy storage unit drives the line cup to accelerate, causing the voltage at the terminal to rise rapidly. The monitoring unit transmits the voltage value at the terminal to the master control unit, and when it rises to a pre-set voltage value, it is considered that the speed of the line cup has reached a sufficient matching state. At this time, the energy storage unit enters the non-working mode, and the line cup enters the free rotation state. The monitoring unit transmits the speed and acceleration signals to the master control unit to assist it in making judgments. The above voltage value for judging the mode switching time can be obtained by repeatedly measuring the specific line cup and statistically analyzing the voltage at the terminal when it reaches the matching state.

[0065] It should be noted that in the embodiments of the present application, the energy storage unit is in the discharging mode or the charging mode, which does not mean that it will necessarily discharge the driving circuit or charge from the driving circuit. Its charging and discharging are also affected by the voltage of the energy storage unit and the voltage at the terminal. For example, after the rod throwing and line throwing are completed, the line cup is in a stationary state. At this time, even if the energy storage unit is in the charging mode, since the electromagnetic coil does not cut the magnetic field to generate induced current, the driving circuit cannot charge the energy storage unit at this time.

[0066] In the process of braking the wire cup, although the charging of the energy storage unit can be realized, with the reduction of the rotation speed of the wire cup, the voltage at the terminal gradually decreases, and when it decreases to the minimum voltage for charging the energy storage unit, the energy storage unit is still in the charging mode, but it cannot be charged. In addition, in the process of winding the wire, the wire cup needs to be rotated in the opposite direction by rotating the handle. The above rotation process will also generate an induced current in the driving circuit, but at this time the rotation speed of the wire cup is generally much smaller than the maximum rotation speed in the process of throwing the wire, that is, the voltage at the terminal cannot directly charge the energy storage unit. In order to utilize the electric energy generated at a low rotation speed of the wire cup, the voltage at the terminal can be boosted when the voltage is low, so that the electric energy generated in the later stage of the rod throwing process and the first process can also be effectively utilized. In addition, the electric energy in the above process can also provide a continuous power supply for the main control unit, so that the entire winding and unwinding comprehensive control system does not need to separately set a battery or other power supply module.

[0067] Therefore, in some preferred embodiments of the present application, as shown in Figure 7 the fish line winding and unwinding comprehensive control system further comprises a residual power management unit, the input end of the residual power management unit is electrically connected with the terminal, and the output end is electrically connected with the energy storage unit and / or the main control unit, for charging the energy storage unit and / or supplying power to the main control unit using the voltage at the terminal.

[0068] In some optional embodiments, the residual power management unit can include a power supply module and a boost module, wherein the power supply module and the boost module can be connected in parallel, that is, each supplies power to the main control unit and charges the energy storage unit after boosting, as shown in Figure 8 .

[0069] In addition, the power supply module and the boost module can also be connected in series, that is, the boost module first boosts the voltage at the terminal, and then charges the energy storage unit, and the power supply module supplies power to the main control unit, as shown in Figure 9 . Using the above series-connected boost module and power supply module, it is not necessary to separately provide a boost chip for each module, thereby further improving the utilization efficiency of the residual power in the later stage of the rod throwing process and the winding process.

[0070] In the winding stage, since the rotation of the wire cup is manually realized by the handle, its rotation speed is difficult to maintain stable, so the voltage output by the boost module often has a low voltage value and large fluctuations. Therefore, in some preferred embodiments, as shown in Figure 9As shown, the residual power management unit further comprises a sampling circuit for detecting the voltage output by the voltage boosting module, and the output of the sampling circuit is connected to the second control signal to control the on-off of the second control unit. When the voltage output by the voltage boosting module is less than a predetermined threshold value, the second control unit will be disconnected by the output of the sampling circuit, so that the energy storage unit enters the non-working mode, that is, the residual power management unit will no longer charge the energy storage unit.

[0076] Meanwhile, the anode of the first charge-discharge capacitor C14 and the anode of the second charge-discharge capacitor C15 are electrically connected with the output end of the voltage boosting module through the current-limiting resistor R1.

[0077] Referring to​Figure 11 In the embodiment, the boosting module of the residual power management unit comprises a second PMOS tube Q11, a second resistor R14, a third charge-discharge capacitor C10, a first inductor L3, a second diode U10, and a boosting chip U9.

[0078] Specifically, the G pole of the second PMOS tube Q11 receives a charging switch signal input by the IO-IN-08 port of the master control chip, the S pole is electrically connected with the terminal FA, and the D pole is grounded through the third charge-discharge capacitor C10.

[0080] Reference Figure 12 In the embodiment, the power supply module of the residual power management unit comprises a third diode D9, a fourth charge-discharge capacitor C9, a third resistor R13, and a fourth diode U8.

[0081] Specifically, the negative pole of the fourth charge-discharge capacitor C9 and the positive pole of the third diode D9 are grounded, the positive pole of the fourth charge-discharge capacitor C9 provides 3.3V power supply for the master control chip, the negative pole of the third diode D9 and the positive pole of the fourth charge-discharge capacitor C9 are electrically connected, and the voltage of the fourth charge-discharge capacitor C9 is clamped at 3.3V.

Through the voltage division of the two resistors in the sampling circuit, the voltage information output by the voltage boosting module can be obtained. In particular, in the winding stage, the main control unit no longer controls the first NMOS tube through the IO-IN-05 end, but the voltage obtained by the sampling circuit is used as the control signal of the first NMOS tube and input to the G pole. Since the speed of manually rotating the wire cup is unstable, the voltage output by the voltage boosting module is also unstable. When the voltage output by the voltage boosting module is low to a certain extent, the voltage output by the sampling circuit can be used to control the first NMOS tube to be disconnected, so as to stop charging the energy storage unit.
