The present invention relates to a motor control device, and more particularly to a motor control device for an electric reel for smelt fishing.

BACKGROUND ART Conventionally, a small electric reel used for catching small fish such as smelt is known (see Patent Document 1). This type of electric reel is mainly used for hole fishing on a frozen lake or for fishing small fish such as smelt from a boat or a dome boat.

JP 2009-240273

When an electric reel for smelt fishing is used for hole fishing on a frozen lake, the needle may get caught in the ice when winding up the line, and each time the hook has to be removed, it is very troublesome.

SUMMARY OF THE INVENTION An object of the present invention is to provide a motor control device for an electric reel for smelt fishing, which can prevent a needle from being caught in ice when winding up a line.

A motor control device according to one aspect of the present invention is a motor control device for an electric reel for smelt fishing, and controls a motor that drives a spool on which a fishing line is wound. The motor control device includes output control means, yarn length measurement means, stop yarn length setting means, output stop means, output reduction means, and mode switching means. The power control means controls the power of the motor to a plurality of power steps. The line length measuring means measures the length of the fishing line let out from the spool. The stop yarn length setting means sets a stop yarn length for stopping the output of the motor. The output stopping means stops the output of the motor when the yarn length measured by the yarn length measuring means reaches the stop yarn length. The output reduction means includes a plurality of control modes for reducing the output of the motor controlled by the output control means before reaching the stop yarn length. The output reduction means reduces the output of the motor in one of a plurality of control modes. The mode switching means switches the control mode of the output reduction means. The plurality of control modes control the output of the motor with a first output that is smaller than the output corresponding to the smallest output step among the plurality of output steps when the first yarn length before reaching the stop yarn length is reached. A first control mode, and a second control mode in which the output of the motor is controlled with a second output smaller than the first output when the second yarn length before reaching the stop yarn length is reached,

In this motor control device, when the control mode of the output reduction means is the second control mode, the output of the motor is the second output which is smaller than the first output in the first control mode before reaching the stop yarn length. controlled. That is, in the second control mode, the fishing line is hoisted at a slower speed than in the first control mode before reaching the stop line length. As a result, it is possible to prevent the needle from being caught in the ice when winding up the line when ice fishing. Moreover, even if the hook is caught in the ice, it is possible to prevent the hook from being deeply caught in the ice. Furthermore, the mode switching means selects the control mode of the output reduction means such as the first control mode for boat fishing and the second control mode for ice fishing, so that the control mode is set to a control mode suitable for the fishing spot and the usage conditions of the user. Since it can be used by switching to , the operability of the electric reel is improved.

The motor control device may further include deceleration yarn length setting means for setting the second yarn length to an arbitrary value within a predetermined range. In this case, the user can set the value of the second yarn length according to the operating conditions such as the thickness of the ice and the height from the surface of the ice to operate the reel. improves.

The predetermined range may be in the range of 0.5 to 2 meters from the stop yarn length. In this case, it is possible to effectively prevent the hook from getting caught in the ice and prevent the prey from coming off the hook.

The first yarn length may be set at a position about 1 meter away from the stop yarn length. In this case, for example, when fishing a small fish such as a smelt in a boat or a dome boat, it is possible to prevent prey from coming off the hook while preventing the reeling of the fishing line from taking too long. .

An electric reel 100 employing an embodiment of the present invention is an electric reel for smelt fishing. More specifically, the electric reel 100 is a small electric reel used, for example, for ice fishing on a frozen lake, or for fishing small fish such as smelt on a boat or dome boat.

As shown in FIGS. 1 and 2, the electric reel 100 includes a reel body 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. and are mainly provided.

The reel body 2 has a mounting portion 2a to which the fishing rod R is mounted at the front. The spool 3 is rotatably supported by the reel body 2 . A fishing line is wound around the outer circumference of the spool 3 . The spool 3 is rotationally driven according to the driving of the motor 4 . The motor 4 is arranged inside the reel body 2 . The motor 4 is driven by power supplied from a power supply (not shown). The display section 5 is arranged on the upper surface of the reel body 2 . The display unit 5 digitally displays various information such as the water depth of the tackle.

The plurality of switch operation units 6 have first to fourth switches 11-14. The first switch 11 and the second switch 12 are switches for turning on and off the drive of the motor 4 . The first switch 11 and the second switch 12 are arranged on the side of the reel body 2 so as to face each other. The third switch 13 and the fourth switch 14 are switches for performing various settings of the electric reel 100 such as setting of the winding speed and switching of control modes to be described later. The third switch 13 and the fourth switch 14 are arranged side by side behind the display section 5 on the upper surface of the reel body 2 .

The clutch operation portion 7 is arranged in front of the display portion 5 on the upper surface of the reel body 2 . The clutch operation unit 7 switches a clutch mechanism (not shown) between an on state and an off state. Rotation of the motor 4 is transmitted to the spool 3 when the clutch mechanism is in the ON state. Rotation of the motor 4 is not transmitted to the spool 3 when the clutch mechanism is in the off state.

FIG. 2 is a block diagram showing the configuration of the control system of the electric reel 100. As shown in FIG. 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 spool sensor 16 is composed of two reed switches arranged side by side. A reed switch detects two magnets attached to the spool 3 . Further, the direction of rotation of the spool 3 can be detected depending on which reed switch issued the detection pulse first.

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

The motor drive circuit 18 PWM-drives the motor 4 . The storage unit 19 is composed of a non-volatile memory such as an EEPROM, and stores data of the result of thread winding learning and various data used when calculating the thread length.

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

The motor control section 21 drives the motor 4 according to the operation of the first switch 11 or the second switch 12 . Here, as switch modes for driving the motor 4, the jogging mode is assigned to the first switch 11 and the continuous mode is assigned to the second switch 12. As shown in FIG. Specifically, the motor control unit 21 continuously drives the motor 4 while the first switch 11 is turned on or when the second switch 12 is turned on. When the second switch 12 is turned on and the motor 4 is driven in the continuous mode, the motor control unit 21 stops driving the motor 4 when the second switch 12 is turned on.

The motor control unit 21 is configured so that the jogging mode is executed with priority over the continuous mode. That is, when the first switch 11 is turned on while the motor 4 is driven in the continuous mode, the motor control section 21 switches the switch mode from the continuous mode to the jogging mode. The motor control unit 21 is configured to switch the switch modes assigned to the first switch 11 and the second switch 12 when the third switch 13 and the fourth switch 14 are simultaneously turned on. may be

FIG. 3 is a block diagram showing the functional configuration of the motor control section 21. As shown in FIG. The motor control section 21 has an output control section 31, a yarn length measuring section 32, a stop yarn length setting section 33, an output stopping section 34, an output reducing section 35, and a mode switching section 36. .

The output control section 31 controls the output of the motor 4 to a plurality of output stages. The plurality of output stages are composed of, for example, six output stages from a first output stage with the lowest output to a sixth output stage with the highest output among the plurality of output stages. The output control unit 31 controls the output of the motor 4 to an output stage selected from a plurality of output stages when the motor 4 is driven according to the operation of the first switch 11 or the second switch 12 . Switching of the output stage is performed, for example, by short-pressing the fourth switch 14 . In this embodiment, the output of the motor 4 is the rotation speed of the motor 4, the rotation speed of the motor 4 corresponding to the first output stage is 0.8 m/s, and the rotation of the motor 4 corresponding to the sixth output stage. The speed is set at 2.8 m/s.

The line length measuring unit 32 measures the line length L of the fishing line let out from the spool 3 in the same manner as the conventional method. For example, the yarn length measuring section 32 measures the yarn length L based on rotational position data regarding the number of rotations of the spool 3 .

The stop yarn length setting unit 33 sets the stop yarn length SL for stopping the output of the motor 4 . It is preferable that the stop line length SL is set at a position where the tackle attached to the fishing line can be easily grasped. The stop yarn length setting unit 33 sets, for example, the yarn length when the third switch 13 is pressed for a long time as the stop yarn length SL.

The output stopping section 34 stops the output of the motor 4 when the yarn length L measured by the yarn length measuring section 32 reaches the stop yarn length SL.

The output reduction section 35 includes a plurality of control modes for reducing the output of the motor 4 controlled by the output control section 31 before reaching the stop yarn length SL. The output reduction unit 35 reduces the output of the motor 4 in one of a plurality of control modes before reaching the stop yarn length SL during yarn winding. The output reduction unit 35 controls the output of the motor 4 according to the operation of the first switch 11 or the second switch 12 from before the yarn length L reaches the stop yarn length SL until it reaches the stop yarn length SL. do. Note that the output reduction unit 35 does not function when the stop yarn length SL is not set.

The multiple control modes include a first control mode 35a and a second control mode 35b. In the present embodiment, the output reduction section 35 operates in either one of the first control mode 35a and the second control mode 35b, from before reaching the stop yarn length SL until reaching the stop yarn length SL. , the output of the motor 4 is reduced.

In the first control mode 35a, when the first yarn length L1 before reaching the stop yarn length SL is reached, the motor 4 is controlled with a first output that is smaller than the output corresponding to the smallest output step among the plurality of output steps. to control the output of The first control mode 35a reduces the output of the motor 4 to the first output when the line length L reaches the first line length L1 while the output control section 31 is hoisting the fishing line. The first control mode 35a controls the output of the motor 4 to the first output from the first yarn length L1 to the stop yarn length SL.

The power of the motor 4 corresponding to the first power is less than the power of the motor 4 corresponding to the first power stage. Therefore, in this embodiment, the rotation speed of the motor 4 corresponding to the first output is lower than 0.8 m/s. The output of the motor 4 corresponding to the first output is pre-stored in the storage unit 19 . The first yarn length L1 is preset, for example, at a position about 1 meter away from the stop yarn length SL. Therefore, in the first control mode 35a, the output of the motor 4 is controlled to the first output from about 1 meter before reaching the stop yarn length SL.

The second control mode 35b controls the output of the motor 4 with a second output smaller than the first output when reaching the second yarn length L2 before reaching the stop yarn length SL. The second control mode 35b reduces the output of the motor 4 to the second output when the line length L reaches the second line length L2 while the fishing line is being hoisted by the output control section 31 . The second control mode 35b controls the output of the motor 4 to the second output from the second yarn length L2 to the stop yarn length SL. In the initial state, the second yarn length L2 is set, for example, at a position about 1 meter away from the stop yarn length SL.

The motor control section 21 may further include a deceleration thread length setting section 37 as shown in FIG. The deceleration yarn length setting section 37 sets the second yarn length L2 to any value within a predetermined range. The predetermined range is preferably 0.5 to 2 meters from the stop yarn length SL. A specific method for setting the second thread length L2 is as follows. For example, when the fourth switch 14 is pressed and held, the mode is switched to the deceleration thread length setting mode. is displayed. When it is detected that the third switch 13 has been turned on while the user has selected a desired yarn length by short-pressing the fourth switch 14, the deceleration yarn length setting unit 37 changes the selected yarn length to the Set as 2 yarn length L2.

The mode switching section 36 switches the control mode of the output reducing section 35 . In this embodiment, when the second yarn length L2 is set by the deceleration yarn length setting unit 37 while the first control mode 35a is selected, the mode switching unit 36 changes the control mode of the output reducing unit 35 to Switch from the first control mode 35a to the second control mode 35b. Further, when the control mode of the output reduction section 35 is the second control mode 35b, when the second control mode 35b is turned off in the deceleration yarn length setting mode, the mode switching section 36 switches the output reduction section 35 is switched from the second control mode 35b to the first control mode 35a. The off operation here means that the third switch 13 is turned on while the fourth switch 14 is pressed briefly to turn off the second control mode 35b in the deceleration thread length setting mode. means

FIG. 4 shows an example of the flow of motor control processing by the motor control section 21 when the control mode of the output reduction section 35 is the second control mode 35b. The output of the motor 4 here is the rotation speed of the motor 4, and feedback control is performed to maintain a predetermined rotation speed when the load acts on the motor 4 and the rotation speed of the spool 3 decreases.

In step S1, it is determined whether or not the yarn length L is greater than the second yarn length L2. That is, in step S1, it is determined whether or not the yarn length L has reached the second yarn length L2. If the second yarn length L2 has not been reached, the process proceeds to step S2, and the motor 4 outputs to the output stage N0 selected from a plurality of output stages according to the operation of the first switch 11 or the second switch 12. to control. That is, until the second yarn length L2 is reached, the output of the motor 4 is controlled by the output control section 31, and the motor 4 rotates at the rotation speed corresponding to the output stage N0. When it is determined that the yarn length L has reached the second yarn length L2, the process proceeds to step S3.

In step S3, it is determined whether or not the yarn length L is greater than the stop yarn length SL. That is, in step S3, it is determined whether or not the yarn length L has reached the stop yarn length SL. If the yarn length L has not reached the stop yarn length SL, the process proceeds to step S4, and the output of the motor 4 is controlled to the second output according to the operation of the first switch 11 or the second switch 12. Therefore, from the second yarn length L2 to the stop yarn length SL, the output of the motor 4 is controlled by the output reducing section 35, and the motor 4 rotates at the rotation speed corresponding to the second output.

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

Note that when the first switch 11 is turned on after the output of the motor 4 is stopped by the output stop unit 34, a plurality of output stages are selected only while the first switch 11 is being turned on. The motor 4 is driven at the output stage N0. That is, when the yarn length L is smaller than the stop yarn length SL, the motor 4 is driven only when the first switch 11 is turned on.

FIG. 5 shows an example of the flow of motor control processing by the motor control section 21 when the control mode of the output reduction section 35 is the first control mode 35a. The motor control process in the first control mode 35a is performed except that the second yarn length L2 in step S1 in FIG. 4 is replaced by the first yarn length L1, and the second output in step S4 in FIG. 4 is replaced by the first output. , the same control processing as in the first control mode 35a is executed. Therefore, detailed description of the motor control process in the first control mode 35a is omitted.

FIG. 6 shows an example of the flow of mode switching processing by the mode switching unit 36. As shown in FIG. In step S11, the mode switching unit 36 reads out the currently set control mode of the output reduction unit 35, and proceeds to step S12.

In step S12, it is determined whether or not the control mode read out in step S11 is the first control mode 35a. If it determines with it being the 1st control mode 35a, it will transfer to step S13.

In step S13, it is determined whether or not the second yarn length L2 has been set. When it is determined that the second yarn length L2 has been set, the process proceeds to step S14 to switch the control mode of the output reducing section 35 from the first control mode 35a to the second control mode 35b. If it is determined in step S13 that the second yarn length L2 has not been determined, 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 first control mode 35a, that is, if it is determined that the control mode is the second control mode 35b, the process proceeds to step S15.

In step S15, it is determined whether or not the second control mode 35b has been turned off as described above. When it is determined that the OFF operation has been performed, the process proceeds to step S16, and the control mode of the output reduction section 35 is switched from the second control mode 35b to the first control mode 35a. If it is determined that the OFF operation has not been performed, 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 second control mode 35b, the second output, which is smaller than the first output, is applied from before reaching the stop yarn length SL. The output of the motor 4 is controlled. That is, in the second control mode 35b, the fishing line is reeled in at a slower speed than in the first control mode 35a. As a result, it is possible to prevent the needle from being caught in the ice when winding up the line when ice fishing. Moreover, even if the hook is caught in the ice, it is possible to prevent the hook from being deeply caught in the ice.

In addition, the mode switching unit 36 switches the control mode of the output reduction unit 35 to the first control mode 35a for boat fishing and the second control mode 35b for ice fishing, depending on the fishing spot and the usage conditions of the user. Since it can be used by switching to a suitable control mode, the operability of the electric reel 100 is improved.
