Motor control device for electric reel

The present invention relates to a motor control device, and in particular, can detect a position by a reverse current, and the reel can be wound in a line by a brushless motor having a two-pole magnet and a three-phase coil of UVW. Motor control unit for a rotating electric reel.

It is known to use a brushless motor for an electric reel that rotates a reel in a winding direction (for example, refer to Patent Document 1). A conventional electric reel is a position sensor using a rotational phase of a rotating member that can detect a brushless motor. The electric reel has a different pulling force because of the different types of fish being caught, so the load varies greatly. When a brushless motor having a position sensor is used for such an electric reel, since the position of the rotary member can be detected regardless of a high-speed rotation with a large load or a high-speed rotation with a small load, the control of the motor is easy.

In the aforementioned conventional configuration, a brushless motor having a position sensor is used. Therefore, it is easy to control the fluctuation of the load. However, the brushless motor with the position sensor is complicated in construction compared to the brushless motor without the sensor. Moreover, since the number of wirings is large by mounting the position sensor, the electric wiring becomes complicated. Therefore, the cost of the electric reel can be increased by using a brushless motor having a position sensor.

On the other hand, in the brushless motor, there is a sense of detecting the rotational phase of the rotating member by the reverse current generated by the rotation of the rotating member when the switch is turned off (OFF). Brushless motor of the detector. The brushless motor without sensor has low cost and easy wiring work because there is no position sensor.

However, when the rotating phase is detected by the reverse current, if the rotating member rotates at a low speed, the reverse current becomes small, and the rotational phase of the rotating member cannot be detected. Therefore, the conventional brushless motor without a sensor is a relatively high-speed and constant-rotation device used for a hard disk (HD) or the like, and is not suitable for use in an electric reel in which the rotational speed fluctuates drastically.

An object of the present invention is to reduce the cost and increase the cost even if a brushless motor without a sensor is used.

The motor control device for the electric reel according to the first aspect of the invention is a stator having a rotating magnet provided with two poles and a three-phase coil provided with UVW, and the rotational phase of the rotating member can be detected by the reverse current. The one-way clutch is used to rotate the spool in the wire winding direction by the brushless motor in which the wire discharge direction is prohibited by the rotation. The motor control device includes a rotation direction determining unit, a rotation phase detecting unit, a start control unit, and a rotation control unit. The rotation direction determining unit detects the rotation direction of the rotating member. The rotational phase detecting unit detects the rotational phase of the rotating member by the reverse current. When the start control unit cannot detect the rotation phase due to the reverse current, the rotation direction determination unit determines that the rotation member is rotated by the rotation direction of the corresponding rotary member until the rotation member rotates in the direction of the winding direction of the complex pattern. The complex mode diagram causes current to flow in the 3-phase coil to start the motor in a predetermined sequence. When the rotation control unit can detect the rotation phase, the brushless motor is controlled by one of the three-phase coils corresponding to the rotation phase detected by the reverse current.

In the motor control device, when the rotational phase detecting unit cannot detect the start of the rotational phase of the rotary member, the start control unit causes the brushless motor to be started. In the start control unit, since the rotation phase of the rotating member cannot be detected, the rotation direction determining unit determines that the current is intermittently rotating the rotating member in the line winding direction by the plural pattern of the rotational phase of the corresponding rotating member. The current is caused to flow to the coil of the three phases. Thereby, the rotating member can be rotated in the winding direction without using the sensor to detect the rotational phase of the rotating member. Therefore, if it is possible to detect the rotational phase of the rotor by the reverse current, it is switched to the control of the rotation control unit. The rotation control unit detects the rotation phase of the rotor by the reverse current, and causes the current to flow in one of the three-phase coils corresponding to the rotation phase.

Here, for example, the brushless motor used in the electric reel which greatly changes the rotational speed due to the fluctuation of the load, when the rotational phase can be detected by the reverse current, and when the rotational phase cannot be detected, respectively Make different controls. Therefore, even if the electric reel is driven by the brushless motor without the sensor, the speed can be increased or decreased, and the cost can be reduced.

The motor control device for the electric reel according to the second aspect of the invention is the device of the first aspect, and the plural mode diagram is six patterns having the first mode to the sixth mode. The first mode diagram is a schematic diagram in which a current flows from the U-phase coil to the V-phase coil. The second mode diagram is a schematic diagram in which a current flows from the U-phase coil to the W-phase coil. The third mode diagram is a schematic diagram in which a current flows from the V-phase coil to the W-phase coil. The fourth mode diagram is a schematic diagram in which a current flows from the V-phase coil to the U-phase coil. The fifth mode diagram is a schematic diagram in which a current flows from the W-phase coil to the U-phase coil. The sixth mode diagram is a schematic diagram in which a current flows from the W-phase coil to the V-phase coil.

The activation control unit has a pattern map circulation unit that moves the current for a predetermined period of time to three phases until the rotation direction determination unit determines that the rotation member is rotating in the wire winding direction in the order of the first mode to the sixth mode diagram. Coil.

In this case, if the current flows in the three-phase coil of the UVW in the order of the first mode to the sixth mode, when the S-pole is facing the U-phase coil, the rotating member will face the line. The winding direction is rotated. Therefore, even if the rotational phase of the rotating member is any one, the rotating member must be rotated in the winding direction by any one of the pattern patterns. Therefore, if the rotation direction determining unit confirms the rotation in the wire winding direction, the rotating member can be rotated in the wire winding direction without using the position sensor.

The motor control device for the electric reel according to the third aspect of the invention is the device according to the second aspect of the invention, further comprising a current detecting unit for detecting a current value of a current flowing through the stator and a flow direction of the current. The rotation direction determining unit determines whether or not the brushless motor is rotating in the wire winding direction by the current value and the current direction detected by the current detecting unit. In this case, the stator of the brushless motor in which the rotation of the rotating member in the wire discharge direction is prohibited by the one-way clutch, if the current that can rotate the rotating member in the wire discharge direction flows, the current cannot be rotated. The value will go high. Therefore, the rotation of the rotating member in the wire winding direction can be judged by the current value and the accuracy of the current direction thereof accurately, and the rotating member can be surely rotated in the wire winding direction irrespective of the rotational phase of the rotating member.

The motor control device for the electric reel according to the fourth aspect of the invention is the device of the second or third aspect, further comprising a motor speed detecting unit for detecting the rotational speed of the motor by the rotational phase, and the rotation control unit, wherein the rotational speed is the first When the speed is equal to or lower than the first speed, the current is transmitted from the first mode to the sixth mode to the three-phase coil in accordance with the rotational phase detected by the rotational phase detecting unit, and the rotational speed is faster than the first speed. When the second speed is equal to or higher than the second speed, the current is caused to flow through the three-phase coil by the interrupt signal and the advance angle control from the rotary phase detecting unit.

In this case, for example, when the brushless motor is rotated at the first speed, for example, 4000 rpm or less, the coil is determined so that the coil is excited to flow the current instead of reading the detected rotation phase. When the brushless motor is rotated at the second speed, for example, 5000 rpm or more, the interrupt signal and the advance angle control from the rotational speed detecting unit are controlled by the three-phase interruption signal following the current exciting position. Current flows in the coil. Therefore, if the rotation of the brushless motor is slow, high-precision rotation control can be performed, and if the speed is high, efficiency can be improved and power consumption can be suppressed.

A motor control device for an electric reel according to a fifth aspect of the invention is the device of any one of claims 1 to 4, further comprising: a reel speed setting unit and a reel speed detecting unit. The reel speed setting unit sets one of the rotation speeds of the reels to a plurality of stages. The reel speed detecting unit detects the rotation speed of the reel. The rotation control unit controls the brushless motor so as to be the reeling speed set by the reel speed setting unit with reference to the detection result of the reel speed detecting unit.

In this case, the reel speed can be controlled by a plurality of stages and can be controlled to a certain extent, and even if the rotation speed of the reel is slowed by the load and the rotation of the motor is slowed down, the rotation phase of the rotating member cannot be detected, and the speed can be low. The control unit rotates the motor with high torque.

According to the present invention, the brushless motor used in the electric reel which greatly changes the rotational speed by the fluctuation of the load is a start which can detect the rotational phase by the reverse current and can not detect the rotational phase. When performing different controls separately. Therefore, even if the electric reel is driven by the brushless motor without the sensor, the speed can be increased or decreased, and the cost can be reduced.

<Configuration of motor>

The motor 12 is, for example, a brushless motor having a rated output of about 180 watts, and is a relatively large-capacity one for use in an electric cord reel.

As shown in Fig. 2, the motor 12 includes a motor case 15, a stator 16 provided on the inner circumferential surface of the motor case 15, a rotating member 17 disposed on the inner peripheral side of the stator 16, and a rotating member. Output shaft 18. The motor case 15 is a member made of an aluminum alloy treated with an alumite treatment in order to improve corrosion resistance. As shown in FIG. 4, the motor casing 15 has a first cover portion 15a disposed at one end, a second cover portion 15b disposed at the other end, and a first cover portion 15a and a second cover portion. The intermediate cover portion 15c between the cover portions 15b. The first lid portion 15a and the second lid portion 15b are bottomed cylindrical members having the same outer diameter, and the cylindrical portions are disposed to face each other. The intermediate cover portion 15c is a tubular member having the same outer diameter as the first cover portion 15a and the second cover portion 15b. The first lid portion 15a, the second lid portion 15b, and the intermediate lid portion 15c are fixed by a plurality of (for example, three) fixing bolts 29 that are screwed into the second lid portion 15b inserted from the first lid portion 15a side. In one. The fixing bolt 29 is an anticorrosive treatment of an anticorrosive film such as plating. Therefore, the intermediate cover portion 15c is held by the first cover portion 15a and the second cover portion 15b. In the cylindrical portion of the second lid portion 15b, as shown in Figs. 2 and 4, at least one of the through holes 15d for drainage is formed along the radial direction. The through hole 15d is provided to remove water generated by condensation or the like inside the motor 12 from the inside of the motor 12. The through hole 15d is provided, for example, three at a lower portion of the leg portion 7d and on both sides thereof.

The stator 16 has a plurality of (for example, three) laminated cores 16a fixed to the intermediate cover portion 15c, and three coils 16b wound in the U phase, the V phase, and the W phase of the laminated core 16a. The laminated core 16a is made of, for example, a non-directional 矽 steel plate. In the laminated core 16a, a plurality of (three) positioning concave portions 16c (second drawing) formed by U-shaped depressions positioned in the rotational direction by the fixing bolts 29 are formed. The exposed portion of the stator 16 is an anti-corrosion treatment of an anti-corrosion film such as plating. In addition, in the fourth figure, the fixing bolts 29 are arranged to have two diameters, but this is only a schematic view. Actually, as shown in Fig. 2, three fixing bolts 29 are arranged at equal intervals in the circumferential direction. .

The rotor 17 includes a magnet 17a having two poles of an S pole and an N pole, and a magnet holder 17b that holds the magnet 17a. The magnet holder 17b is rotatably coupled to the output shaft 18. The rotating member 17 whose exposed portion is subjected to an anticorrosive treatment of an anticorrosive film such as plating.

The output shaft 18 is, for example, a shaft made of a stainless steel alloy, and is rotatably supported by the first cover portion 15a and the second cover portion 15b by a pair of right and left bearings 27. At the first end (the left end of Fig. 5) of the output shaft 18, a one-way clutch 28 for prohibiting the output shaft 18 from rotating in the line discharge direction is attached. The one-way clutch 28 is a roller clutch, and the outer wheel 28a is non-rotatably mounted in the bulging portion 7e of the first side plate 7a of the reel body 1. At the second end (the right end of Fig. 5) of the output shaft 18, a sun gear that constitutes a planetary gear mechanism of a rotation transmission mechanism (not shown) is fixed. The rotation of the motor 12 is transmitted to the spool 10 through the planetary gear mechanism. The planetary gear mechanism decelerates the rotation of the motor 12 by, for example, a reduction ratio of 1/50.

The second cover portion 15b of the motor casing 15 is coupled to the bulging portion 7e, and is fixed by a plurality of (for example, two) fixing bolts 31. Thereby, the motor 12 is fixed to the reel body 1. The three motor wires 34 electrically connected to the coil 16b extend from the end of the second cover portion 15b toward the counter case 4.

In the upper portion of the first side plate 7a and the second side plate 7b of the reel body 1, as shown in Figs. 1 and 2, a counter box for water depth for displaying a fishing group attached to the tip end of the fishing line is fixed. 4.

<Counter Box Composition>

As shown in FIGS. 2 and 3, the counter case 4 includes a case body 19 placed on the front upper portion of the reel body 1, a water depth display portion 22 having a liquid crystal display, and a reel control unit 23 .

The case body 19 is a first side plate 7a and a second side plate 7b that are fixed to the reel body 1. The case body 19 has an upper surface portion 33 and has a synthetic resin upper case member 30 that is exposed to the outside and a lower case member 32 that is fixed to the upper case member 30.

The upper case member 30 is made of, for example, a polyamide resin reinforced with glass short fibers. The upper case member 30 has a display portion which is formed in a fine shape. The upper case member 30 forms a storage space together with the lower case member 32 inside.

A display frame 33a having a display opening having a substantially trapezoidal shape is formed on the display portion of the upper surface portion 33. The opening of the display frame 33a is closed by a transparent cover 37 welded to the upper case member 30.

Further, as shown in FIG. 3, a menu switch SW1, a determination switch SW2, and a memory switch SW3 are disposed behind the display frame 33a. The menu switch SW1 is, for example, a switch for performing a menu operation for a selection operation. The decision switch SW2 is, for example, a switch for operation selected by the menu switch SW. The memory switch SW3 is, for example, a switch for memory of a shed (fish migration layer depth). The menu switch SW1 is a button used to select a display item in the water depth display unit 22. For example, each time the menu switch SW1 is operated, it switches: the upper mode (the mode in which the water depth of the fishing group is displayed from the depth of the water surface), and the bottom mode (the mode in which the water depth of the fishing group is displayed from the water depth of the bottom) . When the menu switch SW1 is held for more than 3 seconds, the control mode of the motor 12 can be switched to the speed constant mode and the tension constant mode each time the button is pressed.

Here, the speed constant mode is a mode in which the upper limit speed of the rotational speed of the reel 10 can be multi-step speed controlled by a plurality of stages (for example, 31 stages) in accordance with the swing position of the adjustment operation lever 5. The tension constant mode is a mode in which the upper limit tension of the tension acting on the fishing line can be multi-stage tension control in a plurality of stages (for example, 31 stages) in accordance with the adjustment of the swing position of the operation lever 5. Further, the 31 stages of the highest stage of the two modes are speed (fast) winding speeds in which the motor 12 is operated by 100% power, and current limitation is not performed, but speed control is not performed. Further, in the speed constant mode, the reel rotation speed of the first stage is controlled to a range of 28 rpm (rpm = number of revolutions per minute) to 30 rpm. Therefore, the rotational speed of the motor 12 is controlled in the range of 1400 rpm to 1500 rpm.

The lower case member 32 is, for example, a frame-shaped member made of a metal having a high heat conductivity and a high thermal conductivity such as an aluminum alloy or a magnesium alloy. The lower casing member 32 is fixed to the upper casing member 30 by a plurality of (for example, four) fixing bolts (not shown). The two circuit boards 20 for the water depth display unit 22 and the reel control unit 23 are mounted on the lower case member 32.

The motor drive circuit 70 including the complex FET (electric field effect transistor) 25 for driving the motor 12 is mounted on the lower surface of the circuit board 20 on the lower side. The FET 25 functions as a switching element that opens and closes the corresponding power ratio when the motor 12 performs PWM (Pulse Width Modulation) control. Further, the FET 25 functions as, for example, a switching element for sequentially exciting and demagnetizing the coil 16b of the stator 16 of the motor 12. Further, a capacitor 21 is connected to the lower circuit board 20. The capacitor 21 has a function of smoothing noise generated from the FET 25. Further, it has a function of rectifying the reverse current of the motor 12. The rotation phase of the motor 12 is detected by rectifying the reverse current. The coil 16b is sequentially excited and demagnetized by the rotational phase control FET 25 thus detected, and the motor 12 is rotated. Then, the rotational speed of the motor 12 is detected by the rotational phase.

As shown in FIG. 3, the water depth display unit 22 has a water depth display area 22a that is displayed in a four-digit 16-segment display in the center, and a three-digit seven-segment memory that is disposed at the lower right side thereof. The water depth display area 22b and the stage display area 22c are arranged in the 7th stage of the left side of the memory water depth display area 22b. The stage display area 22c is a 31-stage display in which the position of the operation lever 5 (stage SC) is adjusted from, for example, 0 to 30. Here, in the water depth display area 22a, since the display of 16 sections is used, the water depth display is more easily visually confirmed.

<Configuration of the reel control unit>

As shown in FIG. 5, the reel control unit 23 has a functional configuration including a motor control unit 60 (an example of a motor control device) that controls the motor 12, and a display control unit 61 that controls the water depth display unit 22. The motor control unit 60 performs PWM control of the motor 12 and performs control for exciting and demagnetizing the complex coil 16b of the stator 16 of the motor 12. In the excitation and degaussing control, the motor control unit 60 detects the rotational phase of the motor 12 by the data obtained by rectifying the reverse current of the motor 12 by the capacitor 21, and sequentially corresponds to the detected rotational phase. The complex coil 16b is excited and demagnetized.

The reel control unit 23 is connected to an adjustment operation lever 5, a menu switch SW1, a determination switch SW2, and a memory switch SW3. Further, the reel sensor 41 for detecting the rotational speed and the rotational direction of the reel 10 and the ON/OFF for turning on and off the coil 16b and including the motor 12 for PWM driving are connected. The motor drive circuit 70 of the FET 25 and the capacitor 21, the buzzer 47, the water depth display unit 22, the memory unit 46, and other input and output units. The motor drive circuit 70 is provided with a current detecting portion 70a for detecting a current value flowing through the motor 12. The current detecting unit 70a can detect the current direction in addition to the current value flowing through the motor.

The reel sensor 41 is composed of two reed switches arranged side by side in parallel, and any of the reed switches can detect the rotation direction of the reel 10 by judging whether or not a detection pulse is emitted. . Further, the number of rotations and the rotation speed of the reel can be detected by detecting the pulse.

The memory unit 46 is constituted by a nonvolatile memory such as an EEPROM. As shown in FIG. 6, the memory unit 46 is provided with a display data storage area 50 for storing display data such as the position of the shed (fish migration layer depth), and the actual line length and the number of reels to be displayed. The line length data storage area 51 of the line length data memory for the relationship, and the rotation data memory area 52 for storing the winding speed (rpm) and the winding torque (current value) of the reel 10 of the corresponding stage SC, and A variety of data memory data memory areas 53.

In the rotation data storage area 52, the upper limit speed Vsc of each stage SC in the speed-constant mode, the lower limit value Vsc1 of the upper limit speed Vsc, and the upper limit value Vsc2 are stored, and the stages SC in the tension-fix mode are stored. The data of the lower limit value Qsc1 and the upper limit value Qsc2 of the upper limit tension Qs. Various materials regarding the line length are accommodated in the data memory area 53. It accommodates, for example, a rim stop position.

The motor control unit 60 is configured by a software, and includes a rotational phase detecting unit 62, a motor current control unit 63, a rotation direction determining unit 64, a start control unit 65, a rotation control unit 66, and a roll. The cylinder speed detecting unit 67, the reel speed control unit 68, and the mode switching unit 69. The rotational phase detecting unit 62 detects the rotational phase of the motor 12 by data obtained by rectifying the reverse current of the motor 12. It is also possible to detect the rotational speed of the motor 12 by the passage of time of the rotational phase.

The motor current control unit 63 controls the current value flowing through the motor 12 in a plurality of stages (for example, 31 stages) in accordance with the swing operation position of the adjustment operation lever 5. That is, the control of the motor 12 is performed in the constant tension mode.

The rotation direction determining unit 64 determines the rotation direction of the motor 12 when the current flows from the predetermined pattern to the motor 12 during the control of the start control unit 65. It is determined whether or not the motor 12 is rotated in the wire winding direction by the current value and the current direction detected by the current detecting portion 70a in the motor drive circuit 70. As described above, the output shaft 18 of the motor 12 is prohibited from rotating in the wire discharge direction by the one-way clutch 28. Therefore, if the motor 12 rotates in the line discharge direction, the current flowing to the motor 12 increases. By the increase in the current value, it is detected that the motor is rotating in the line discharge direction.

The start control unit 65 has a pattern map circulation unit 65a. When the motor 12 is rotated at a speed at which the predetermined rotational speed is not full, and the rotation phase generated by the reverse current cannot be detected, the current shown in FIG. 8 has the first mode. The predetermined pattern diagram of the sixth mode diagram flows sequentially from the U-phase coil 16b to the W-phase coil 16b so that the current is changed every 1000 rpm for a predetermined time (for example, 0.5 second). Further, each time the direction of rotation is detected, the start control is terminated when the rotary member 17 is rotated in the wire take-up direction.

The predetermined pattern shown in Fig. 8 is composed of six pattern diagrams from the first pattern to the sixth pattern. In each of the patterns, when the rotary member 17 is at the position as shown in Fig. 8, the motor 12 is rotated in the wire take-up direction. The first mode diagram is such that a current flows from the U phase toward the V phase coil 16b as indicated by an arrow A. At this time, as described above, when the rotary member 17 is located outside the position shown in Fig. 8, the rotary member 17 does not rotate or rotate in the line discharge direction. When the rotation direction determining unit 64 determines that the rotor 17 is not rotating in the wire winding direction, the current flows through the second pattern. In the second mode diagram, the current flows from the U-phase coil to the V-phase coil 16b as indicated by an arrow B. Similarly, when the rotor 17 has not rotated in the wire winding direction, the third mode diagram flowing from the arrow C, the fourth mode diagram flowing from the arrow D, the fifth mode diagram flowing by the arrow E, In the sixth mode diagram in which the arrow F flows, the current flows from the U phase toward the V-phase coil 16b until the rotor 17 rotates in the wire winding direction. Further, in the third mode diagram, a current flows from the V-phase coil to the W-phase coil. In the fourth mode diagram, current flows from the V-phase coil toward the U-phase coil. The fifth mode diagram is such that a current flows from the W-phase coil toward the U-phase coil. In the sixth mode diagram, current flows from the W-phase coil toward the V-phase coil. When the current flows from the first mode map until the sixth mode diagram, the rotating member 17 can be rotated in the wire winding direction regardless of whether the rotating pattern 17 is in any phase. Therefore, until the rotor 17 rotates in the wire winding direction, the current of the next pattern is flowed while determining the rotation direction. When it is determined that the rotary member 17 is rotated in the wire winding direction, the processing is terminated.

When the motor 12 rotates and the rotation phase can be detected by the reverse current generated when the FET 25 is turned on or off (ON/OFF), the rotation control unit 66 corresponds to the rotation of the rotating member 17 of the detected motor 12. The phase causes current to flow to the three coils 16b. An example of the detection signal for the rotational phase for rectifying the reverse current that will occur is as shown in FIG. In Fig. 7, the detection signal is generated when the current flows in the order from the U phase to the W phase as shown in Fig. 8. Fig. 8 is a schematic diagram showing a predetermined pattern used when being controlled by the activation control unit 65. In the case of the 3-phase 2-pole motor 12, in the predetermined pattern diagram, the rotating member 17 is provided in any one of the six pattern diagrams, regardless of the rotational phase of the rotating member 17. Both can be rotated in the direction of the wire winding.

At the time of the rotation control, the current is caused to flow by a predetermined pattern corresponding to the detection result of the rotational phase. Further, the positive electrode side of each of the U-phase, the V-phase, and the W-phase is turned ON/OFF by a cycle corresponding to the reel speed or current value. On the other hand, the negative side of each coil 16b is subjected to power control by a PWM control of a cycle of, for example, 20 kHz in accordance with the set reel speed or current value.

The reel speed detecting unit 67 detects the speed of the reel 10 used in the motor control unit 60 and the rotation direction of the reel 10 by the output from the reel sensor 41.

The reel speed control unit 68 is a swing operation position corresponding to the adjustment operation lever 5 as the reel speed setting unit, and controls the rotation speed of the reel 10 in a plurality of stages (for example, 31 stages). That is, the motor 12 is controlled in the speed constant mode.

The mode switching unit 69 is for switching between the constant mode and the speed constant mode. As described above, for example, the switching operation of the operation mode is realized by the long-press operation of the menu switch SW1 for 3 seconds or longer.

In the electric reel having such a configuration, when the fishing line is discharged, the clutch is opened (OFF) by operating the clutch operating member 11 forward (rear). When the clutch is turned off (OFF), the reel 10 is in a freely rotating state, and the fishing line is discharged from the reel 10 by the weight of the plumb installed on the fishing line. When the fishing line is discharged, the reel 10 is rotated in the line discharge direction, and the water depth display of the pulse water depth display unit 22 is changed by the detection of the reel sensor 41. When the fishing group reaches the shed (the depth of the fish migration layer), the operation lever 2 is rotated in the winding direction of the wire, and the clutch is turned on (ON) by a clutch return mechanism (not shown) to stop the discharge of the fishing line.

When the fish is hooked, the operation lever 5 is operated to wind up the fishing line. When the adjustment operation lever 5 is swung clockwise in the first figure, the maximum value of the rotation speed of the reel 10 or the tension of the fishing line can be set in accordance with the swing angle.

<Operation of the reel control unit>

Next, the specific control operation of the reel control unit 23 will be described based on the control flowchart shown after FIG. In addition, the following description is only an example of the control program of the present invention, and the control program of the present invention is not limited to the contents shown in the following flowcharts.

When the power source is put into the electric reel by a power cable (not shown), the initial setting is performed in step S1 of Fig. 9. Various variables and flags are reset in this initial setting. Further, the rim stop position FN (an example of the stop water depth) is set to a standard rim stop position, that is, the first line length L1 (for example, 6 m).

Next, display processing is performed in step S2. In the display processing, various display processing such as water depth display is performed. Here, the stage SC is displayed in the stage display area 22c.

In step S3, it is determined whether or not the water depth LX calculated by each of the operation modes described later is equal to or smaller than the first line length L1. In step S4, a determination is made as to whether or not any of the switches SW1 to SW3 or the switch for adjusting the operation lever 5 is pressed. And it is judged in step S5 whether the reel 10 is rotated. This determination is made by the output of the reel sensor 41. In step S6, it is judged whether or not other commands and inputs are operated.

When the water depth LX is equal to or smaller than the first line length L1, the flow proceeds from step S3 to step S7. In step S7, it is determined whether or not the water depth is stopped for 5 seconds or longer. When the water depth of 6 m or less is stopped for 5 seconds or longer, the operation of removing the fish caught in the rim is often performed, or the operation of attaching the bait to the fishing group or the like is performed. Therefore, if it is determined that the stop is 5 seconds or longer, the process proceeds to step S8, and the water depth LX at this time is set to the ship edge stop position FN. If the 5 seconds is not full, the process proceeds from step S7 to step S4.

When the switch input is operated, the process proceeds from step S4 to step S9 to execute the switch input shown in Fig. 10. When the rotation of the reel 10 is detected, the flow proceeds from step S5 to step S10. Each operation mode process is executed in step S10. When another command or input is operated, the process proceeds from step S6 to step S11 to perform other processing.

In the switch input processing of step S6, it is determined by step S15 of Fig. 10 whether or not the adjustment operation lever 5 is operated. In step S16, it is determined whether or not the menu switch SW1 is pressed for 3 seconds or longer. In step S17, it is judged whether or not the other switches are operated. The operation of the other switches includes: normal operation of the menu switch SW1, operation of the switch SW2 and the memory switch SW3, and the like.

If it is determined that the adjustment operation lever 5 is oscillated, the flow proceeds from step S15 to step S18. In step S18, the number of stages SC of the adjustment operation lever 5 is read. A rotary encoder (not shown) is provided in the adjustment operating lever 5, and the output of the rotary encoder is read. In step S19, it is judged whether or not the adjustment operation lever 5 is operated to the stage SC=0. When the phase SC is "0", the process proceeds to step S20, the motor 12 is turned off (OFF), and the process proceeds to step S16. If the phase SC is not "0", the process proceeds to step S21.

In step S21, the motor rotation control process shown in Fig. 11 is performed, and the process proceeds to step S22. In step S22, it is determined whether or not any one of the speed constant mode or the constant tension mode is set due to the long press operation of the menu switch SW1. When the speed constant mode is set, the process proceeds from step S22 to step S23. The reel speed control process for realizing the speed constant mode is performed in step S23, and then the process proceeds to step S16. In this reel speed control process, the feedback control motor 12 sets the target reel rotation speed set in each stage SC.

If the menu switch SW1 is operated by a long press, the process proceeds from step S16 to step S25. In step S25, it is judged whether or not the speed constant mode is set. When the speed constant mode is set, the process proceeds from step S25 to step S26 and is set to the tension setting mode, and then the process proceeds to step S17. When the tension constant mode is set, the process proceeds from step S25 to step S27 to set the tension setting mode, and the process proceeds to step S17.

When the tension constant mode is set, the process proceeds from step S22 to step S24. In step S24, the motor current control process for realizing the tension constant mode is performed, and then the process proceeds to step S16. In the motor current control process, the feedback control motor 12 sets the target current value set in each stage SC.

When the other switch input is performed, the process proceeds from step S17 to step S2. For example, another switch input process such as a change from the bottom mode and another mode setting is performed, and then the process returns to the main routine shown in FIG. Program.

In the motor rotation control processing of step S21, it is determined in step S31 of Fig. 11 whether or not the motor 12 has been started. When the motor 12 has been started, the process proceeds to step S40. If the motor 12 is not activated, the process proceeds to step S31. In step S31, the variable N (N is a positive integer) for sequentially flowing a current toward the coil 16b from the first mode map is set to "1". In step S33, the rotation speed of 1000 rpm is such that the current of the Nth pattern which can rotate the motor 12 flows toward the coil 16b. In step S34, it is judged whether or not the rotation direction of the motor 12 is the wire winding direction. In the case of the rotation of the wire take-up direction, the process proceeds from step S34 to step S40.

When the motor 12 is not rotating in the wire winding direction, the process proceeds from step S34 to step S35. In step S35, the variable N is incremented by one in order to cause the current of the next pattern to flow. In step S36, it is determined whether or not the variable N is "7". When the variable N is "7", the process proceeds to step S37 to set the variable N to "1", and the process proceeds to step S38. In step S38, it is judged whether or not the output of the pattern map exceeds 0.5 second. If the mode map is output, if it exceeds 0.5 seconds, the process proceeds to step S40. When the variable N is not 7, the process proceeds from step S36 to step S33, and the next mode map is output. These steps are repeated until the motor 12 is rotated in the wire take-up direction.

When the motor 12 rotates in the wire winding direction, the process proceeds from step S34 to step S40. In step S40, the rotational speed V of the motor 12 and the current power DR are read. These are memorized in the memory unit 46. In step S41, it is determined whether or not the rotational speed of the motor 12 is 4000 rpm or less. When the rotation of the motor 12 is 4000 rpm or less, the process proceeds from step S41 to step S43. In step S43, low speed control processing is performed. Specifically, as long as the signal for displaying the rotational phase shown in FIG. 7 obtained by the reverse current is read, the excitation position can be determined without performing the angle control by calculating the rotational phase. However, if the high-speed rotation is controlled by this, the efficiency is deteriorated, and the power consumption is remarkably large. Here, if it is determined in step S41 that the rotation of the motor 12 exceeds 4000 rpm, the process proceeds to step S42. In step S42, it is determined whether or not the rotation of the motor 12 is 5000 rpm or more. When it is determined that the rotation of the motor 12 is 5000 rpm or more, the process proceeds from step S42 to step S44 to perform high-speed processing. In this high-speed processing, position detection and advance angle control are added to the interrupt signal of the rotating phase signal to perform excitation. Here, the judgment of steps S41 and S42 is set to a loss of 1000 rpm in order to prevent chattering due to the determination of the same rotational speed.

Specifically, the excitation position calculated from the current speed is synchronized by the interrupt signal. For example, the rotational speed is calculated from the signal of the rotational phase of the W phase, and the rotational speed is obtained at intervals of 100 μsec. Further, the angles are reset by the following three conditions to adjust the rotation angle.

1. When the position detection of the U phase is interrupted in the first and sixth pattern diagrams, the position (angle) is 0 degree.

2. When the position detection of the V phase is interrupted in the second and third pattern diagrams, the position (angle) is 120 degrees.

3. When the position detection of the U phase is interrupted in the fourth and fifth pattern diagrams, the position (angle) is 240 degrees.

Here, in order to prevent an interruption in an unnecessary angle caused by noise or the like, a signal for locking the rotation phase of the next phase of the current excitation position is detected. Specifically, in the case of the second mode diagram, the detection of the V phase is performed, in the case of the fourth mode diagram, the detection of the W phase is performed, and in the case of the sixth mode diagram, the detection of the U phase is performed. The above operation is performed every time the motor 12 rotates. The motor 12 is rotated while adjusting the advance angle. If these processes are completed, the process proceeds to step S22.

In each of the operation mode processes in step S10, it is determined in step S51 of Fig. 12 whether or not the rotation direction of the spool 10 is the line discharge direction. This determination is made by whether or not the reed switch of any of the reel sensors 41 is pulsed first. When the rotation direction of the reel 10 is determined as the line discharge direction, the flow proceeds from step S51 to step S52. In step S52, each time the number of reel rotations is reduced, the data stored in the line length data storage area 51 is read based on the number of reels of the reel and the water depth (the line length to be ejected) LX is calculated. This water depth LX is displayed by the display processing of step S2. In step S53, it is judged whether or not the obtained water depth LX coincides with the shed (fish migration layer depth) position or the bottom position, that is, whether the fishing group reaches the shed (fish migration layer depth) or the bottom. The position of the shed (fish migration layer depth) or the bottom position is that the display data of the memory unit 46 can be set in the memory area 50 by pressing the memory switch SW3 when the fishing group reaches the shed (fish migrating depth) or the bottom. In step S54, it is determined whether or not it is another mode such as a learning mode.

When the water depth coincides with the position of the shed (fish migration layer depth) or the bottom position, the flow proceeds from step S53 to step S55, and the buzzer 47 is sounded in order to notify that the fishing group has reached the shed (fish migration layer depth) or the bottom. In the case of another mode, the process proceeds from step S54 to step S56, and the other modes designated are executed. When there is no other mode, the operation mode processing is ended and the process returns to the main routine.

If it is determined that the rotation of the reel 10 is the wire winding direction, the process proceeds from step S51 to step S57. In step S57, the data stored in the line length data storage area 51 is read based on the number of reels of the reel and the water depth LX is calculated. This water depth LX is displayed by the display processing of step S2.

In step S58, it is determined whether or not the rim stop position is reached. When the ship edge stop position FN is reached, the process proceeds from step S58 to step S59. In step S59, the buzzer 47 is made to sound in order to notify that the fishing set is already at the rim. In step S60, the motor 12 is turned off (OFF). Thus, when the fish is caught and the fishing group is recovered and the bait is exchanged, the fish and the fishing group are placed in an easily removable position. Return to the main routine if it is not taken to the rim stop position.

<Features>

(A) The motor control unit 60 is a stator 16 having a rotor 17 having two magnets 17a and a three-phase coil 16b provided with UVW, and the rotation phase of the rotor 17 can be detected by the reverse current. The reel 10 is rotated in the wire take-up direction by using the motor 12 such as a brushless motor in which the rotation of the wire discharge direction is prohibited by the one-way clutch 28. The motor control unit 60 includes a rotation direction determination unit 64, a rotation phase detection unit 62, a start control unit 65, and a rotation control unit 66. The rotation direction determining unit 64 detects the rotation direction of the rotor 17. The rotational phase detecting unit 62 detects the rotational phase and the rotational speed of the rotating member by the reverse current. When the start control unit 65 cannot detect the rotational phase due to the reverse current, the complex mode map corresponding to the rotational phase of the rotary member 17 is determined in a predetermined order until the rotational direction determining unit 64 determines that the rotary member 17 is in the complex mode map. Any one of the coils is rotated in the winding direction, and a current is caused to flow to the coil of the three phases to start the motor 12. When the rotation phase is detectable, the rotation control unit 66 controls the motor 12 so that the current flows in the three-phase coil 16b in accordance with the rotation phase detected by the reverse current.

In the motor control unit 60, when the rotational phase detecting unit 62 cannot detect the rotation phase of the rotor 17, the starter control unit 65 activates the brushless motor 12. In the start control unit 65, since the rotational phase of the rotor 17 cannot be detected, the complex mode map of the rotational phase of the corresponding rotary member 17 until the rotational direction determining unit 64 determines that the rotary member 17 is rotating in the wire winding direction. The current is sequentially and intermittently flowed to the coil 16b of the three phases. Thereby, the rotating member 16b can be rotated in the wire winding direction without detecting the rotational phase of the rotary member 17 using the sensor. Therefore, when the rotational phase of the rotor 16b can be detected by the reverse current, it is switched to the control by the rotation control unit 66. The rotation control unit 66 detects the rotation phase of the rotor 16b by the reverse current, and causes a current to flow to one of the three-phase coils 16b in accordance with the rotation phase.

Here, if a motorless brushless motor 12 that is used in an electric reel for changing the rotational speed due to a change in load is used, for example, when the rotational phase can be detected by the reverse current, Different controls when rotating the phase cannot be detected. Therefore, even if the electric reel is driven by the brushless motor 12 without the sensor, the speed can be increased or decreased, and the cost can be reduced.

(B) In the motor control unit 60, the complex pattern diagram is six pattern diagrams having the first pattern to the sixth pattern. The first mode diagram is a schematic diagram in which a current flows from the U-phase coil to the V-phase coil. The second mode diagram is a schematic diagram in which a current flows from the U-phase coil to the W-phase coil. The third mode diagram is a schematic diagram in which a current flows from the V-phase coil to the W-phase coil. The fourth mode diagram is a schematic diagram in which a current flows from the V-phase coil to the U-phase coil. The fifth mode diagram is a schematic diagram in which a current flows from the W-phase coil to the U-phase coil. The sixth mode diagram is a schematic diagram in which a current flows from the W-phase coil to the V-phase coil.

The start control unit 65 has a pattern flow unit 65a that allows the current to be predetermined in the order of the first mode to the sixth mode until the rotation direction determining unit 64 determines that the rotor 17 is rotating in the wire winding direction. The coil 16b flows in the three phases.

In this case, when the current flows in the three-phase coil 16b of the UVW in the order of the first mode to the sixth mode, the rotating member 17 will be in a state where the S-pole and the U-phase coil 16b face each other. Rotate in the direction of the wire take-up. Therefore, even if any one of the rotational phases of the rotary member 17 is rotated, the rotary member 17 is necessarily rotated by the pattern of either one in the winding direction. Therefore, if the rotation direction determining unit 64 confirms the rotation in the wire winding direction, the rotary member 17 can be rotated in the wire winding direction without using the position sensor.

(C) The motor control unit 60 further includes a current detecting unit 70a for detecting a current value of a current flowing through the stator 16 and a flow direction of the current. The rotation direction determining unit 64 determines whether or not the motor 12 is rotating in the wire winding direction by the current value and the current direction detected by the current detecting unit 70a. In this case, if the current that rotates the rotor 17 in the line discharge direction flows through the stator 16 of the motor 12 in which the rotation of the rotor 17 in the line discharge direction is prohibited by the one-way clutch 28, the rotary member 17 Cannot rotate so that the current value becomes higher. Therefore, the rotation of the rotating member 17 in the wire winding direction can be judged by the current value and the accuracy of the current direction thereof accurately, and the rotating member 17 can be surely rotated in the wire winding direction irrespective of the rotational phase of the rotating member 17.

(D) The motor control unit 60 further includes a motor speed detecting unit for detecting the rotational speed of the motor 12 by the rotational phase, and the rotation control unit 66 corresponds to the rotational phase when the rotational speed is equal to or lower than the first speed. The rotation phase detected by the detecting unit 62 causes the current to flow from the first mode to the sixth mode to the three-phase coil, and when the rotation speed is higher than the first speed, the second speed is borrowed. The current is directed to the three-phase coil by the interrupt signal and the advance angle control from the rotational phase detecting portion 62.

In this case, for example, when the rotation of the brushless motor is, for example, 4000 rpm or less of the first speed, the detected rotation phase is not read to perform the advance control, and the coil that determines the excitation causes the current to flow. When the brushless motor is rotated at a second speed, for example, 5000 rpm or more, the interrupt signal and the advance angle control from the rotational speed detecting unit 62 are used to interrupt the next phase of the current excitation position. Current is caused to flow to the coil 16b. Thereby, when the rotation speed of the brushless motor 12 is slow, high-precision rotation control can be performed, and when the speed is high, efficiency can be improved and power consumption can be suppressed.

(E) The motor control unit 60 further includes an adjustment operation lever 5 and a reel speed detection unit 67. The operation lever 5 is adjusted to set the rotation speed of the reel 10 to a plurality of stages. The reel speed detecting portion 67 detects the rotational speed of the reel 10. The rotation control unit 65 controls the motor 12 to be the reel rotation speed set by the adjustment operation lever 5 with reference to the detection result of the reel speed detection unit 67.

In this case, the reel speed can be controlled from a plurality of stages and controlled to some extent, and even if the reel speed is lowered by the load, the rotation of the motor 12 is slowed down and the rotational phase of the rotary member 17 cannot be detected, The rotation control unit 66 rotates the motor by high torque.
