Disclosure of Invention

[ problem to be solved by the invention ]

When the electric reel for fishing pond swamp fish is used for drilling ice fishing in an icy lake, the fishing hook may be hooked on ice when the fishing line (fishing line) is wound up, and the hook must be unhooked every time, which is very troublesome.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a motor control device for an electric reel for a pond fish, which can prevent (prevent) a fish hook from being caught on ice when a fishing line is wound.

[ solution for solving problems ]

The motor control device according to an aspect of the present invention is a motor control device for an electric fishing reel for a pond fish, which controls a motor for driving a spool for winding a fishing line. The motor control device has an output control mechanism, a wire length measuring mechanism, a stop wire length setting mechanism, an output stop mechanism, an output reducing mechanism, and a mode switching mechanism. The output control means controls the output of the motor in a plurality of output levels. The line length measuring mechanism measures the line length of the fishing line paid out from the spool. The stop wire length setting mechanism sets a stop wire length for stopping the output of the motor. The output stopping mechanism stops the output of the motor when the line length measured by the line length measuring mechanism reaches the stop line length. The output reducing mechanism includes a plurality of control modes, and the plurality of control modes are modes for reducing the output of the motor controlled by the output controlling mechanism from the point at which the stop wire length is about to be reached. The output reducing mechanism reduces the output of the motor in any one of a plurality of control modes. The mode switching mechanism switches the control mode of the output reducing mechanism. The plurality of control modes include a 1 st control mode and a 2 nd control mode, wherein in the 1 st control mode, when a 1 st line length to be a stop line length is reached, an output of the motor is controlled with a 1 st output, the 1 st output being smaller than an output corresponding to a smallest output level among the plurality of output levels; in the 2 nd control mode, when the 2 nd line length to reach the stop line length is reached, the output of the motor is controlled with the 2 nd output smaller than the 1 st output.

In the motor control device, when the control mode of the output reduction mechanism is the 2 nd control mode, the output of the motor is controlled at the 2 nd output smaller than the 1 st output in the 1 st control mode from the point when the stop line length is about to be reached. That is, in the 2 nd control mode, the fishing line is wound up at a speed slower than that in the 1 st control mode from the point when the line length is about to reach the stop line length. Therefore, when drilling ice fishing on ice, the fishing hook can be prevented from being hooked on the ice when the fishing line is reeled. Further, even if the fishhook is caught on ice, the fishhook can be prevented from being caught deeply on ice, and therefore, the fishhook can be released easily. Further, the mode switching mechanism can switch the control mode of the output reduction mechanism to the control mode suitable for the fishing ground and the use situation of the user, as in the case of switching to the 1 st control mode at the time of kayaking, switching to the 2 nd control mode at the time of ice fishing in a hole, and the like, and therefore, the operability of the electric reel can be improved.

The motor control device may further include a deceleration line length setting mechanism that sets the 2 nd line length to an arbitrary value within a predetermined range. In this case, the user can set the value of the 2 nd line length according to the thickness of the ice, the height from the surface of the ice at which the user operates the reel, and other operating conditions, and therefore, the operability of the electric reel can be improved.

The specified range can be within 0.5-2 m from the stop line. In this case, the occurrence of the hook being caught by the fishhook on ice can be effectively suppressed, and the occurrence of the caught object falling off from the fishhook can be suppressed.

The 1 st line length may be set at a position about 1 meter from the stop line length. In this case, for example, when small fish such as pond fish are fished using a boat or a dome boat, it is possible to suppress the time consuming winding of the fishing line and to suppress the falling of the captured object from the hook.

[ Effect of the invention ]

According to the present invention, it is possible to provide a motor control device for an electric fishing reel for a pond fish capable of suppressing the occurrence of a hook catching on ice when a fishing line is reeled.

Detailed Description

The electric reel 100 used in one embodiment of the present invention is an electric reel for fishing pond fish. More specifically, the electric reel 100 is a small-sized electric reel used for ice fishing in a bore hole in an icy lake or fishing small fish such as pond fish using a boat or a dome boat.

As shown in fig. 1 and 2, the electric reel 100 mainly includes a reel unit 2, a spool 3, a motor 4, a display unit 5, a plurality of switch operation units 6, a clutch operation unit 7, and a control unit 8.

The reel unit 2 has a mounting portion 2a on the front portion thereof for mounting the fishing rod R. The spool 3 is rotatably supported by the reel unit 2. A fishing line is wound around the outer periphery of the spool 3. The spool 3 is driven to rotate by the driving of the motor 4. The motor 4 is disposed inside the reel unit 2. The motor 4 is driven by electric power supplied from a power supply unit not shown. The display unit 5 is disposed on the upper surface of the reel unit 2. Various information such as the depth of water in which the hook assembly is located is digitally displayed on the display unit 5.

The plurality of switch operation units 6 include 1 st to 4 th switches 11 to 14. The 1 st switch 11 and the 2 nd switch 12 are switches for turning on and off the drive of the motor 4. The 1 st switch 11 and the 2 nd switch 12 are disposed on the side portions of the reel unit 2 at positions facing each other. The 3 rd switch 13 and the 4 th switch 14 are switches for performing various settings of the electric reel 100, such as setting of a take-up speed and switching of a control mode to be described later. The 3 rd switch 13 and the 4 th switch 14 are arranged side by side on the upper surface of the reel unit 2 at the rear portion of the display unit 5.

The clutch operation unit 7 is disposed on the front portion of the display unit 5 on the upper surface of the reel unit 2. The clutch operation unit 7 switches a clutch mechanism, not shown, between an engaged state and a disengaged state. When the clutch mechanism is in the engaged state, the rotation of the motor 4 is transmitted to the spool 3. When the clutch mechanism is in the disengaged state, the rotation of the motor 4 is not transmitted to the spool 3.

Fig. 2 is a block diagram showing the configuration of the control system of the electric reel 100. As shown in fig. 2, the control unit 8 is connected to the switch operation unit 6, the spool sensor 16, the spool counter 17, the motor drive circuit 18, the storage unit 19, and the display unit 5.

The bobbin sensor 16 is composed of two reed switches arranged in tandem. The reed switch detects two magnets attached to the spool 3. Further, the rotation direction of the spool 3 can be detected by which reed switch first emits the detection pulse.

The spool counter 17 is a counter that counts the number of times the spool sensor 16 is turned on and off, and by this count value, rotational position data relating to the rotational speed of the spool 3 can be obtained.

The motor drive circuit 18 PWM-drives the motor 4. The storage unit 19 is configured by a nonvolatile memory such as an EEPROM, for example, and stores data of the winding learning result, various data used for calculating the wire length, and the like.

The control unit 8 has, as functional configurations, a motor control unit 21 (an example of a motor control device) and a display control unit 22, wherein the motor control unit 21 controls the motor 4; the display control unit 22 controls the display unit 5.

The motor control section 21 drives the motor 4 in response to an operation of the 1 st switch 11 or the 2 nd switch 12. Here, as the switching mode for driving the motor 4, the 1 st switch 11 is assigned the inching mode, and the 2 nd switch 12 is assigned the continuous mode. Specifically, the motor control unit 21 continuously drives the motor 4 only during the 1 st switch 11 is pressed or only when the 2 nd switch 12 is pressed once. When the 2 nd switch 12 is operated once to drive the motor 4 in the continuous mode, the motor control unit 21 stops the driving of the motor 4 when the 2 nd switch 12 is pressed again.

The motor control unit 21 is configured to execute the inching mode in preference to the continuous mode. That is, when the 1 st switch 11 is operated to be turned on in a state where the motor 4 is driven in the continuous mode, the motor control section 21 switches the switch mode from the continuous mode to the inching mode. The motor control unit 21 may be configured to switch the switching patterns assigned to the 1 st switch 11 and the 2 nd switch 12 when the 3 rd switch 13 and the 4 th switch 14 are simultaneously operated to be on.

Fig. 3 is a block diagram showing a functional configuration of the motor control unit 21. The motor control unit 21 has an output control unit 31, a thread length measuring unit 32, a stop thread length setting unit 33, an output stop unit 34, an output reducing unit 35, and a mode switching unit 36.

The output control unit 31 controls the output of the motor 4 in a plurality of output levels. The plurality of output levels are, for example, 6 output levels from the 1 st output level with the smallest output to the 6 th output level with the largest output among the plurality of output levels. The output control unit 31 controls the output of the motor 4 at an output level selected from a plurality of output levels when the motor 4 is driven in response to the operation of the 1 st switch 11 or the 2 nd switch 12. The switching of the output level is performed by, for example, a short press of the 4 th switch 14. In the present embodiment, the output of the motor 4 is the rotational speed of the motor 4, the rotational speed of the motor 4 corresponding to the 1 st output level is set to 0.8m/s, and the rotational speed of the motor 4 corresponding to the 6 th output level is set to 2.8 m/s.

The line length measuring section 32 measures the line length L of the fishing line paid out from the reel 3 by the same method as in the related art. For example, the thread length measuring section 32 measures the thread length L based on the rotational position data relating to the rotational speed of the spool 3.

The stop line length setting unit 33 sets a stop line length SL for stopping the output of the motor 4. The stop line length SL is preferably set to a position where it is easy to grasp a hook assembly mounted on the fishing line. The stop line length setting unit 33 sets the line length of the 3 rd switch 13, which is pressed for a long time, as the stop line length SL, for example.

The output stop unit 34 stops the output of the motor 4 when the cord length L measured by the cord length measuring unit 32 reaches the stop cord length SL.

The output reduction section 35 includes a plurality of control modes that reduce the output of the motor 4 controlled by the output control section 31 from the point at which the stop line length SL is to be reached. When winding up the fishing line, the output reducing section 35 reduces the output of the motor 4 in any one of the plurality of control modes from the point when the stop line length SL is about to be reached. The output reducing section 35 controls the output of the motor 4 in response to the operation of the 1 st switch 11 or the 2 nd switch 12 during a period from when the line length L is about to reach the stop line length SL until the stop line length SL is reached. The output reduction unit 35 does not function when the stop line length SL is not set.

The plurality of control modes include a 1 st control mode 35a and a 2 nd control mode 35 b. In the present embodiment, the output reduction unit 35 reduces the output of the motor 4 in any one of the 1 st control mode 35a and the 2 nd control mode 35b from just before the stop line length SL is reached to the stop line length SL.

In the 1 st control mode 35a, upon reaching the 1 st wire length L1 which will reach the stop wire length SL, the output of the motor 4 is controlled with a 1 st output, wherein the 1 st output is smaller than the output corresponding to the smallest output level among the plurality of output levels. In the 1 st control mode 35a, when the fishing line is being reeled in by the output control section 31, the output of the motor 4 is reduced to the 1 st output when the line length L reaches the 1 st line length L1. In the 1 st control mode 35a, the output of the motor 4 is controlled to the 1 st output during a period from the 1 st line length L1 until the stop line length SL is reached.

The output of the motor 4 corresponding to the 1 st output is smaller than the output of the motor 4 corresponding to the 1 st output level. Therefore, in the present embodiment, the rotation speed of the motor 4 corresponding to the 1 st output is slower than 0.8 m/s. The output of the motor 4 corresponding to the 1 st output is stored in the storage unit 19 in advance. The 1 st line length L1 is preset to a position about 1 meter from the stop line length SL, for example. Therefore, in the 1 st control mode 35a, the output of the motor 4 is controlled to the 1 st output from the time when the stop line length SL is reached by about 1 meter.

In the 2 nd control mode 35b, upon reaching the 2 nd wire length L2 which is about to reach the stop wire length SL, the output of the motor 4 is controlled at the 2 nd output which is smaller than the 1 st output. In the 2 nd control mode 35b, when the fishing line is being reeled in by the output control section 31, if the line length L reaches the 2 nd line length L2, the output of the motor 4 is reduced to the 2 nd output. In the 2 nd control mode 35b, the output of the motor 4 is controlled to the 2 nd output during the period from the 2 nd wire length L2 until the stop wire length SL is reached. In the initial state, the 2 nd wire length L2 is set to a position about 1 meter from the stop wire length SL, for example.

As shown in fig. 3, the motor control unit 21 may further include a deceleration line length setting unit 37. The deceleration-line-length setting section 37 sets the 2 nd line length L2 to an arbitrary value within a predetermined range. The predetermined range is preferably 0.5 to 2 meters from the stop line length SL. A specific setting method of the 2 nd wire length L2 is, for example, to switch to the deceleration wire length setting mode when the 4 th switch 14 is pressed long, and to display a screen for the deceleration wire length setting mode on the display unit 5 by the display control unit 22. When the user detects that the 3 rd switch 13 is turned on in a state where the user selects a desired line length by short-pressing the 4 th switch 14, the deceleration-line-length setting unit 37 sets the selected line length to the 2 nd line length L2.

The mode switching unit 36 switches the control mode of the output reduction unit 35. In the present embodiment, when the 2 nd lane length L2 is set by the deceleration lane length setting unit 37 when the 1 st control mode 35a is selected, the mode switching unit 36 switches the control mode of the output reduction unit 35 from the 1 st control mode 35a to the 2 nd control mode 35 b. Further, when the control mode of the output reduction unit 35 is the 2 nd control mode 35b, and the 2 nd control mode 35b is turned off in the deceleration line length setting mode, the mode switching unit 36 switches the control mode of the output reduction unit 35 from the 2 nd control mode 35b to the 1 st control mode 35 a. The phrase "operated to be turned off" here means that the 3 rd switch 13 is operated to be turned on in a state where the item of turning off the 2 nd control mode 35b is selected by short-pressing the 4 th switch 14 in the deceleration line length setting mode.

Fig. 4 shows an example of the flow of the motor control process of the motor control unit 21 when the control mode of the output reduction unit 35 is the 2 nd control mode 35 b. The output of the motor 4 here is the rotational speed of the motor 4, and when a load acts on the motor 4 to decrease the rotational speed of the spool 3, feedback control is performed so as to maintain a predetermined rotational speed.

In step S1, it is determined whether the wire length L is greater than the 2 nd wire length L2. That is, in step S1, it is determined whether the wire length L reaches the 2 nd wire length L2. If the 2 nd line length L2 is not reached, the process proceeds to step S2, and the output of the motor 4 is controlled at the output level N0 selected from the plurality of output levels in response to the operation of the 1 st switch 11 or the 2 nd switch 12. That is, until the 2 nd line length L2 is reached, the output of the motor 4 is controlled by the output controller 31, and the motor 4 rotates at a rotation speed corresponding to the output level N0. If it is determined that the line length L reaches the 2 nd line length L2, the process proceeds to step S3.

In step S3, it is determined whether the wire length L is larger than the stop wire length SL. That is, in step S3, it is determined whether the wire length L reaches the stop wire length SL. If the line length L does not reach the stop line length SL, the process proceeds to step S4, and the output of the motor 4 is controlled to the 2 nd output in response to the operation of the 1 st switch 11 or the 2 nd switch 12. Therefore, during the period from the 2 nd wire length L2 until the stop wire length SL, the output of the motor 4 is controlled by the output reducing portion 35, and the motor 4 rotates at the rotation speed corresponding to the 2 nd output.

When it is determined in step S3 that the wire length L has reached the stop wire length SL, the process proceeds to step S5, and the output of the motor 4 is stopped by the output stop unit 34.

After the output of the motor 4 is stopped by the output stop unit 34, when the 1 st switch 11 is operated to be turned on, the motor 4 is driven at the output level N0 selected from the plurality of output levels only while the 1 st switch 11 is operated to be turned on. That is, when the line length L is smaller than the stop line length SL, the motor 4 is driven only when the 1 st switch 11 is operated to be turned on.

Fig. 5 shows an example of the flow of the motor control process of the motor control unit 21 when the control mode of the output reduction unit 35 is the 1 st control mode 35 a. In the motor control process in the 1 st control mode 35a, the same control process as that in the 1 st control mode 35a is performed except that the 2 nd wire length L2 of step S1 in fig. 4 is replaced with the 1 st wire length L1, and the 2 nd output of step S4 in fig. 4 is replaced with the 1 st output. Therefore, detailed description of the motor control process in the 1 st control mode 35a is omitted.

Fig. 6 shows an example of the flow of the mode switching process performed by the mode switching unit 36. In step S11, the mode switching section 36 reads the control mode of the currently set output reducing section 35, and shifts to step S12.

In step S12, it is determined whether or not the control pattern read in step S11 is the 1 st control pattern 35 a. If it is determined that the control pattern 1 is the control pattern 35a, the process proceeds to step S13.

In step S13, it is determined whether the 2 nd wire length L2 is set. When it is determined that the 2 nd line length L2 is set, the process proceeds to step S14, and the control mode of the output reduction unit 35 is switched from the 1 st control mode 35a to the 2 nd control mode 35 b. In step S13, if it is determined that the 2 nd line length L2 is not set, the mode switching process is not executed.

If it is determined in step S12 that the control mode read in step S11 is not the 1 st control mode 35a, that is, if it is determined that this control mode is the 2 nd control mode 35b, the process proceeds to step S15.

In step S15, it is determined whether the 2 nd control mode 35b is operated to be off as described above. If it is determined that the operation is off, the process proceeds to step S16, and the control mode of the output reduction unit 35 is switched from the 2 nd control mode 35b to the 1 st control mode 35 a. In a case where it is determined not to be operated as off, the mode switching process is not executed.

In the motor control unit 21 of the electric reel 100 configured as described above, when the control mode of the output reduction unit 35 is the 2 nd control mode 35b, the output of the motor 4 is controlled at the 2 nd output smaller than the 1 st output from the point when the line length SL is about to reach the stop line length SL. That is, in the 2 nd control mode 35b, the fishing line is wound at a speed slower than that of the 1 st control mode 35 a. Therefore, when drilling ice fishing on ice, the fishing hook can be prevented from being hooked on the ice when the fishing line is reeled. Further, even if the fishhook is caught on ice, the fishhook can be prevented from being caught deeply on ice, and therefore, the fishhook can be released easily.

Further, the mode switching unit 36 can switch the control mode of the output reduction unit 35 to the control mode suitable for the fishing ground and the user's use situation, as in the case of switching to the 1 st control mode 35a at the time of kayaking, switching to the 2 nd control mode 35b at the time of ice fishing in a hole, and the like, and therefore, the operability of the electric reel 100 can be improved.

< other embodiments >

While one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the invention. In particular, the plurality of embodiments and modifications described in the present specification can be combined as desired.

(a) In the above embodiment, the output control unit 31 controls the output of the motor 4 in 6 output levels, but the number of output levels is not limited to the above embodiment.

(b) In the above embodiment, the rotational speed of the spool 3 is detected as the output of the motor 4 and the feedback control is performed, but the output of the motor 4 may be controlled so that the winding torque becomes a predetermined value by controlling the current value supplied to the motor 4. Alternatively, the winding diameter of the spool 3 may be calculated and the tension may be controlled to a predetermined value.

(c) In the above embodiment, when the 2 nd linear length L2 is set by the deceleration linear length setting unit 37 when the 1 st control mode 35a is selected, the control mode of the output reduction unit 35 is switched from the 1 st control mode 35a to the 2 nd control mode 35b, but the switching of the control mode is not limited to the above embodiment. For example, when the 3 rd switch 13 or the 4 th switch 14 is operated by a predetermined operation, the control mode of the output reduction unit 35 may be sequentially switched regardless of the setting of the 2 nd line length L2. Alternatively, the control mode of the output reduction unit 35 may be selectable by the user in response to the operation of the 3 rd switch 13 or the 4 th switch 14.
