Description

Motor control device

The present invention relates to a motor control device, in particular to a motor control device of an electric reel for ice fishing.

Conventionally, there is known a small electric reel used when fishing small fishes such as scorpionfish (refer to Patent Document 1). This kind of electric reel is mainly used for fishing in holes on frozen lakes, or when fishing small fish such as scorpionfish in small boats and dome boats.

[The problem to be solved by the invention]

When the electric reel for ice fishing is used in hole fishing on a frozen lake, the needle is caught by the ice when the thread is wound up, and the hook must be unhooked every time, which is very troublesome.

The subject of the present invention is to provide a motor control device for an electric reel for ice fishing in which the hand is caught by ice hooks when the line is wound up. [Technical means to solve the problem]

The motor control device of one aspect of the present invention is a motor control device of an electric reel for ice fishing, and controls a motor that drives a reel on which a fishing line is wound. The motor control device includes an output control unit, a wire length measurement unit, a stop wire length setting unit, an output stop unit, an output reduction unit, and a mode switching unit. The output control unit controls the motor output in a multi-stage motor output. The line length measuring part measures the line length of the fishing line discharged from the reel. The stop line length setting part is to set the stop line length to stop the motor output. The output stop part is the line length measured by the line length measuring part and the motor output is stopped when the stop line length is reached. The output reduction unit is a complex control mode that includes: the output of the motor controlled by the output control unit is reduced before reaching the stop line length. The output reduction unit reduces the motor output in any one of the plural control modes. The mode switching unit switches the control mode of the output reduction unit. The plural control mode is the first control mode that includes: when the first line length before the stop line length is reached, the motor output is controlled by the first output that is smaller than the motor output corresponding to the smallest output level among the multiple motor outputs , And a second control mode in which the motor output is controlled by a second output smaller than the first output when the second line length before the stop line length is reached.

In this motor control device, when the control mode of the output reduction unit is the second control mode, the motor output is controlled by the second output, which is smaller than the first output in the first control mode, before the stop line length is reached. That is, in the second control mode, the fishing line starts to be wound up at a slower speed than in the first control mode before the stop line length is reached. As a result, when hole fishing is performed on ice, it is possible to prevent the hand from being caught by the ice when the line is rolled up. Furthermore, even if the needle is hooked by ice, it is still possible to suppress the needle from being deeply hooked by the ice, so the hook of the needle can be easily released by spitting out the fishing line. Furthermore, with the mode switching unit, the first control mode can be switched when fishing in small boats, and the second control mode can be switched when fishing in holes on the ice, so that the control mode of the output reduction unit can be switched to suitable for fishing grounds and The control mode of the user's usage status, so the operability of the electric cord reel can be improved.

The motor control device may further include a deceleration wire length setting unit that sets the second wire length to an arbitrary value within a predetermined range. In this case, since the user can set the second wire length value according to the thickness of the ice and the height from the surface of the ice, such as operating conditions of the reel operation, the operability of the electric reel can be improved.

The specified range can also be within the range of 0.5 to 2 meters away from the stop line length. In this case, the needle can be effectively restrained from being hooked by ice, and the prey can be restrained from falling off the needle.

The first line length can also be set to a position away from the stop line length by about 1 meter. In this case, for example, when fishing small fishes such as western tako in small boats and dome boats, it is possible to prevent the reeling time of the fishing line from being too long, and it is possible to prevent the prey from falling off the needles. [Effects of the invention]

According to the present invention, it is possible to provide a motor control device for an electric reel for ice fishing that can prevent the hand from being caught by ice when the line is wound up.

The electric reel 100 used in one embodiment of the present invention is an electric reel for ice fishing. In more detail, the electric reel 100 is, for example, a small electric reel used for fishing in a hole on a frozen lake or fishing for small fishes such as sagefish in small boats and dome boats.

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

The reel main body 2 has a mounting part 2a for mounting a fishing rod R on the front part. The reel 3 is rotatably supported on the reel body 2. The fishing line is wound around the outer circumference of the reel 3. The reel 3 is driven to rotate in response to the driving of the motor 4. The motor 4 is arranged inside the reel body 2. The motor 4 is driven by electric power supplied from a power supply unit (not shown). The display unit 5 is arranged on the upper surface of the reel body 2. In the display unit 5, various information such as the water depth of the fishing rig is digitally displayed.

The plural switch operation unit 6 has first to fourth switches 11-14. The first switch 11 and the second switch 12 are switches that turn on (ON) and turn off (OFF) the driving of the motor 4. The first switch 11 and the second switch 12 are arranged on the sides of the reel main body 2 at positions facing each other. The third switch 13 and the fourth switch 14 are switches for various settings of the electric cord reel 100 for setting the winding speed, switching the control mode described later, and the like. The third switch 13 and the fourth switch 14 are located on the upper surface of the reel main body 2 and are arranged side by side at the rear of the display unit 5.

The clutch operating part 7 is arranged on the upper surface of the reel main body 2 at the front part of the display part 5. The clutch operating unit 7 switches a clutch mechanism (not shown) to an ON state and an OFF state. When the clutch mechanism is in the ON state, the rotation of the motor 4 is transmitted to the spool 3. When the clutch mechanism is in the OFF 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 reel sensor 16, and the reel counter 17, the motor drive circuit 18, the memory unit 19, and the display unit 5.

The reel sensor 16 is composed of two reed switches arranged side by side. The reed switch is used to detect the two magnets installed on the reel 3. In addition, the rotation direction of the reel 3 can be detected by the detection pulse first issued by any of the reed switches.

The reel counter 17 is a counter that counts the number of on/off (ON/OFF) of the reel sensor 16, and the rotation position data related to the number of rotations of the reel 3 can be obtained from the count value.

The motor drive circuit 18 drives the motor 4 by PWM. The storage unit 19 is composed of, for example, a non-volatile memory such as EEPROM, and is used for storing data of the winding learning result and various data used in calculating the wire length.

The control unit 8 as a functional member includes 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 unit 21 drives the motor 4 in response to the operation of the first switch 11 or the second switch 12. Here, as for the switching mode driven by the motor 4, the first switch 11 is assigned the inching mode, and the second switch 12 is assigned the continuous mode. Specifically, the motor control unit 21 continuously drives the motor 4 while the first switch 11 is turned on (ON), or when the second switch 12 is turned on (ON). The motor control unit 21 stops the driving of the motor 4 when the second switch 12 is turned on (ON) and the motor 4 is driven in the continuous mode. When the second switch 12 is turned on (ON), the driving of the motor 4 is stopped.

The motor control unit 21 allows the jog mode to be executed with priority over the continuous mode. That is, when the first switch 11 is turned ON when the motor 4 is driven in the continuous mode, the motor control unit 21 switches the switching mode from the continuous mode to the inching mode. In addition, when the third switch 13 and the fourth switch 14 are simultaneously turned on (ON), the motor control unit 21 may replace the switching patterns assigned to the first switch 11 and the second switch 12 with each other.

FIG. 3 is a block diagram showing the functional components of the motor control unit 21. As shown in FIG. The motor control unit 21 includes an output control unit 31, a wire length measurement unit 32, a stop wire length setting unit 33, an output stop unit 34, an output reduction unit 35, and a mode switching unit 36.

The output control unit 31 controls the output of the motor 4 in multiple stages. The multi-stage motor output is composed of, for example, 6-stage motor output from the first stage motor output of the smallest output stage motor output to the sixth stage motor output of the largest output stage motor output among the multi-stage motor outputs. The output control unit 31 controls the output of the motor 4 by the selected stage from the multi-stage motor output when the motor 4 is driven in response to the operation of the first switch 11 or the second switch 12. The switching of the multi-stage motor output is performed by, for example, a short voltage of the fourth switch 14. In this embodiment, the output of the motor 4 refers to the rotation speed of the motor 4, and the rotation speed of the motor 4 corresponding to the first stage motor output is set to 0.8 m/s, which corresponds to the speed of the motor 4 corresponding to the sixth stage motor output. The rotation speed is set to 2.8m/s.

The line length measuring unit 32 measures the line length L of the fishing line discharged from the reel 3 by the same method as the conventional one. For example, the wire length measuring unit 32 measures the wire length L based on the rotation position data on the number of rotations of the reel 3.

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

The output stop part 34 is the line length L measured by the line length measuring part 32 and stops the output of the motor 4 when the stop line length SL is reached.

The output reduction unit 35 is a complex control mode that includes the output of the motor 4 controlled by the output control unit 31 and starts to decrease before reaching the stop line length SL. The output reduction unit 35 starts to reduce the output of the motor 4 in any one of the plural control modes before reaching the stop line length SL during the line winding. The output reducing unit 35 controls the output of the motor 4 in response to the operation of the first switch 11 or the second switch 12 during the period from before the line length L reaches the stop line length SL to the stop line length SL. In addition, the output reducing unit 35 does not function when the stop line length SL is not set.

The plural control modes include a first control mode 35a and a second control mode 35b. In the present embodiment, the output reducing unit 35 is a control mode in which one of the first control mode 35a and the second control mode 35b is controlled, and the output is reduced from before the stop line length SL to the stop line length SL. The output of the motor 4 decreases.

In the first control mode 35a, when the first line length L1 before the stop line length SL is reached, the output of the motor 4 is controlled by the first output that is smaller than the motor output corresponding to the smallest output stage among the multiple stages of motor output . In the first control mode 35a, when the fishing line is wound up by the output control unit 31, when the line length L reaches the first line length L1, the output of the motor 4 is reduced to the first output. The first control mode 35a controls the output of the motor 4 to the first output during the period from the first line length L1 to the stop line length SL.

The output of the motor 4 corresponding to the first output is smaller than the output of the motor 4 corresponding to the first stage motor output. Therefore, in this embodiment, the rotation speed of the motor 4 corresponding to the first output is slower than 0.8 m/s. The output of the motor 4 corresponding to the first output is stored in the memory 19 in advance. The first line length L1 is, for example, set in advance to be about 1 meter away from the stop line length SL. Therefore, in the first control mode 35a, the control of the output of the motor 4 to the first output is started without reaching about 1 meter before the stop line length SL.

In the second control mode 35b, when the second line length L2 before the stop line length SL is reached, the output of the motor 4 is controlled by a second output that is smaller than the first output. In the second control mode 35b, when the fishing line is wound up by the output control unit 31, when the line length L reaches the second line length L2, the output of the motor 4 is reduced to the second output. In the second control mode 35b, the output of the motor 4 is controlled to the second output during the period from the second line length L2 to the stop line length SL. The second line length L2 is set in an initial state, for example, at a position away from the stop line length SL by about 1 meter.

The motor control unit 21 may further include a deceleration line length setting unit 37 as shown in FIG. 3. The deceleration line length setting unit 37 sets the second line length L2 to an arbitrary value within a predetermined range. The specified range is preferably a range away from the stop line length SL from 0.5 to 2 meters. The specific setting method of the second line length L2 is, for example, when the fourth switch 14 is pressed and held to switch to the deceleration line length setting mode, the display control unit 22 displays the deceleration line length setting mode on the display unit 5. Picture. In addition, when the third switch 13 detects that the line length desired by the user is selected by the short-pressing of the fourth switch 14, the deceleration line length setting unit 37 sets the selected line The length is set to the second line length L2.

The mode switching unit 36 switches the control mode of the output reduction unit 35. In this embodiment, when the first control mode 35a is selected, and the second line length L2 is set by the deceleration line length setting unit 37, the mode switching unit 36 changes the control mode of the output reduction unit 35 from the first control mode. The first control mode 35a is switched to the second control mode 35b. Also, when the control mode of the output reduction unit 35 is the second control mode 35b, in the deceleration line length setting mode, when the second control mode 35b is turned off (OFF), the mode switching unit 36 is the output reduction unit The control mode of 35 is switched from the second control mode 35b to the first control mode 35a. The OFF operation here is in the deceleration line length setting mode, and the second control mode 35b is turned off (OFF) by the short voltage of the fourth switch 14 in the state where the item is selected. This means that the third switch 13 is turned on.

Fig. 4 is an example of the flow of the motor control process of the motor control unit 21 when the control mode of the display output reduction unit 35 is the second control mode 35b. The output of the motor 4 here is the rotation speed of the motor 4, and when a load is applied to the motor 4 and the rotation speed of the spool 3 is reduced, feedback control is performed to maintain the predetermined rotation speed.

In step S1, it is determined whether the line length L is greater than the second line length L2. That is, in step S1, it is determined whether the line length L has reached the second line length L2. If the second line length L2 is not reached, the process moves to step S2, corresponding to the operation of the first switch 11 or the second switch 12, the output of the motor 4 is controlled by the output stage N0 selected from the multi-stage motor output. That is, until the second line length L2 is reached, the output of the motor 4 is controlled by the output control unit 31, and the motor 4 is rotated at the rotation speed corresponding to the output stage N0. If it is determined that the line length L has reached the second line length L2, the process moves to step S3.

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

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

In addition, after the output of the motor 4 is stopped by the output stop unit 34, when the first switch 11 is turned on (ON), only during the period when the first switch 11 is turned on (ON) is selected from the multi-stage motor output The output stage N0 of the motor 4 is driven. That is, the line length L is smaller than the stop line length SL, and the motor 4 is driven only when the first switch 11 is turned on (ON).

Fig. 5 is an example of the flow of the motor control process of the motor control unit 21 when the control mode of the display output reduction unit 35 is the first control mode 35a. The motor control process in the first control mode 35a is except that the second line length L2 of step S1 in Figure 4 is switched to the first line length L1, and the second output of step S4 in Figure 4 is switched to the first line length L1. Except for 1 output, the same control processing as in the first control mode 35a is executed. Therefore, a detailed description of the motor control processing in the first 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 unit 36 reads the control mode of the output reduction unit 35 that is currently set, and moves to step S12.

In step S12, it is determined whether or not the control mode read in step S11 is the first control mode 35a. If it is judged that it is the 1st control mode 35a, it moves to step S13.

In step S13, it is determined whether the second line length L2 is set. If it is determined that the second line length L2 is set, the process moves to step S14, and the control mode of the output reduction unit 35 is switched from the first control mode 35a to the second control mode 35b. If it is determined in step S13 that it is not the case of the second line length L2, the mode switching process is not executed.

In step S12, when the control mode read in step S11 is determined to be not the first control mode 35a, that is, when it is determined that the control mode is the second control mode 35b, the process moves to step S15.

In step S15, it is judged whether or not the second control mode 35b is operated to be OFF as described above. When it is judged that it is OFF operation, it moves to step S16, and switches the control mode of the output reduction part 35 from the 2nd control mode 35b to the 1st control mode 35a. If it is judged that it has not been turned off (OFF), the mode switching process is not executed.

In the motor control section 21 of the electric reel 100 configured as described above, when the control mode of the output reduction section 35 is the second control mode 35b, the second output, which is smaller than the first output, starts before the stop line length SL is reached. The output of the motor 4 is controlled. That is, in the second control mode 35b, the fishing line is wound up at a slower speed than in the first control mode 35a. As a result, when hole fishing is performed on ice, it is possible to prevent the hand from being caught by the ice when the line is rolled up. Furthermore, even if the needle is hooked by ice, it is still possible to suppress the needle from being deeply hooked by the ice, so the hook of the needle can be easily released by spitting out the fishing line.

In addition, the mode switching unit 36 can switch to the first control mode 35a during boat fishing and the second control mode 35b during ice fishing. Therefore, the control mode of the output reduction unit 35 can be changed according to the fishing ground and the use. The user's use condition is switched to a suitable control mode to use, so the operability of the electric cord reel 100 can be improved.

<Other embodiments> Although one embodiment of the present invention has been described above, the present invention is not limited to the above-mentioned embodiment, and various changes can be made without departing from the essential scope of the invention. In particular, the plural embodiments and modifications described in this specification can be combined arbitrarily as needed.

(b) In the foregoing embodiment, the output of the motor 4 is to detect the rotation speed of the reel 3 and perform feedback control. However, it is also possible to control the value of the current supplied to the motor 4 so that the winding torque becomes a predetermined value. The output of motor 4 is controlled. Alternatively, the wire diameter of the spool 3 may be calculated so that the tension becomes a predetermined value and controlled.

(c) In the foregoing embodiment, when the first control mode 35a is selected, and the second line length L2 is set by the deceleration line length setting unit 37, the control mode of the output reduction unit 35 is changed from the first control mode 35a is switched to the second control mode 35b, but the switching of the control mode is not limited to the aforementioned embodiment. For example, regardless of the setting of the second line length L2, when the third switch 13 or the fourth switch 14 is subjected to a predetermined operation, the control mode of the output reduction unit 35 may be sequentially switched. Alternatively, the user may select the control mode of the output reduction unit 35 in response to the operation of the third switch 13 or the fourth switch 14.
