Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device for an electric reel, and more particularly, to a control device for an electric reel having a booster capable of increasing a supply voltage of a power supply.

[0002]

2. Description of the Related Art An electric reel capable of rotating a spool when a fishing line is wound up by a motor is, for example, a 10 reel.
It is often used when catching fish migrating at a depth of 0 m or more from a boat. This type of electric reel generally has duty control means, and the angler can change the line winding speed by operating an acceleration / deceleration switch provided on the operation unit of the electric reel.

Such duty control of the electric reel is generally performed within a range of a voltage supplied by a power supply (hereinafter, referred to as a power supply voltage). It is also possible to rotate. An electric reel for increasing the voltage in this manner is disclosed, for example, in Japanese Utility Model Laid-Open No. 5-85264. Here, an automatic switch or a manual switch, which is a winding speed changing switch (hereinafter referred to as an acceleration / deceleration switch), is operated to wind the fishing line at the power supply voltage. Letting you wind the fishing line at high speed.

[0004]

In the above-mentioned electric reel, the acceleration / deceleration switch and the boosting switch are provided as separate switches, and the angler (operator) performs the pressure increasing operation separately from the spool acceleration / deceleration operation. . However, if a switch for increasing the voltage is provided separately from the acceleration / deceleration switch and operated by the angler, the operability is poor. In addition, the angler determines whether or not it is OK to operate the boost switch, and specifically states that the boost switch should be operated when the food is replaced or the fish escapes. Recognizing this, the user must replace the finger from the acceleration / deceleration switch to the boost switch to wind the fishing line.

[0005] It is an object of the present invention to generate a pressurized state for improving a line winding speed in an electric reel, and it is an object of the present invention to reduce the trouble of a judge's judgment and a man's operation.

[0006]

A control device for an electric reel according to a first aspect of the present invention is a device for controlling a motor for rotating a spool by electric power supplied from a power supply. Unit, a control unit, and a boosting unit. The acceleration / deceleration switch is a switch operated by the angler to change the winding speed of the fishing line.
The storage unit stores power setting values corresponding to the winding speed of the fishing line in n stages from the first-stage power setting value to the n-th-stage power setting value. The reading unit reads the power set value of the corresponding stage from the storage unit based on the operation of the acceleration / deceleration switch. The control unit changes the power supplied to the motor at the supply voltage of the power supply when the stage of the power set value read by the reading unit is any of the first stage to the (na) th stage. . Further, when the stage of the set value read by the reading unit is larger than the (na) th stage, the control unit changes the power supplied to the motor by increasing the supply voltage of the power supply. The booster boosts the supply voltage of the power supply according to a command from the controller.

Here, the rotation speed of the motor that rotates the spool can be changed based on the n-stage power set values. Then, power is supplied to the motor at the supply voltage of the power supply up to the (na) th stage, and power is supplied to the motor by increasing the voltage in stages larger than the (na) stage. These stages are changed by operating the speed-up / down switch, and when the stage goes up, the control unit automatically issues a command to the boosting unit to boost the voltage.

By operating the acceleration / deceleration switch in this way, it is possible to generate a state in which the voltage is increased in addition to the acceleration / deceleration with the supply voltage of the power supply. For this reason, the angler who operates the electric reel according to the present invention can use the boosted state as one of the normal winding speeds without performing a difficult operation or determination. That is, in the present invention, it is possible to save the angler's judgment and the operation of the angler's operation regarding the generation of the boosted state, as compared with the case where the step-up switch is provided separately from the speed-up / down switch.

According to a second aspect of the present invention, there is provided the electric reel control device according to the first aspect, wherein the control unit is increasing the supply voltage of the power supply to the boosting unit and overloads the motor. When there is a fear, the boost is automatically released. Since the boosting state is automatically generated by the operation of increasing the speed of the acceleration / deceleration switch, the boosting state may occur even when the load is large, such as a state where fish is applied. If the load applied to the motor is large and the boosting state continues, the motor drive element and the like may be damaged. However, in this case, the boosting is automatically canceled when the boosting unit is boosting the supply voltage of the power supply and there is a possibility that the motor may be overloaded. Therefore, according to the control device of the present invention, damage to the motor, the motor drive element, and the like can be suppressed.

A control device for an electric reel according to a third aspect of the present invention is the device according to the first or second aspect, wherein the control unit is configured to increase the supply voltage of the power supply to the boosting unit, and that the fishing line When the coil is wound up to the winding position, the pressure is automatically released. Some electric reels have a function of automatically stopping winding when a fishing line is wound up to a certain water depth. For example, there is an electric reel in which winding is stopped at a certain water depth such that a mechanism returns to a hand when a pole is set up. In such an electric reel, it is desirable to reduce the winding speed before the winding stops.

In this case, when the fishing line is wound up to a predetermined winding position, for example, when the fishing line is wound up a few meters before the position where the winding is stopped, if the pressure is in a boosted state, the control unit performs this operation. Release. Therefore, the winding speed is slowed down just before the winding stop position, and the winding can be stopped easily. Invention 4
The control device for an electric reel according to the invention is the device according to the invention 2 or 3, further comprising a display unit. The display unit
The stage of the power set value read by the reading unit is displayed to the angler. When the control unit automatically cancels the boost,
The reading unit reads the (na) -th power set value from the storage unit.

Here, when the boosting is automatically canceled by the control unit, the motor is driven by the power set value of the (na) -th stage, which is the fastest stage when the boosting is not performed. Then, it informs the angler via the display unit that the pressure has been automatically released and the step has changed. An electric reel control device according to a fifth aspect of the present invention is the device according to any one of the first to fourth aspects, wherein a = 1.

Here, assuming that one stage is in the boosted state, the speed of the motor is controlled by a plurality of stages in the supply voltage of the power supply and one stage in the boosted state. For example, it is conceivable that the first to fifth stages are set with a duty of 50% to 100% in the supply voltage of the power supply, and the duty of 100% in the boosted state is set to the sixth stage.

The control unit 20 includes a microcomputer including a CPU, a RAM, a ROM, an I / O interface, and the like disposed in the operation panel 4, and executes various control operations described later according to a control program. The control unit 20 includes various buttons of the operation key unit 6, a spool rotation sensor 21 including a pair of reed switches for detecting the rotation direction and the number of rotations of the spool 10, a relay switch 22, and a motor 12. A current detection sensor 23 for detecting the supplied current value and a temperature sensor 24 are connected. Current detection sensor 23
Detects the current supplied to the motor 12 by detecting the partial voltage across the FET 25a, which is a motor drive element used in the PWM drive circuit 25. When an FET having a current detection function is used, the current detection sensor 23 is unnecessary. The temperature sensor 24 indirectly detects the temperature of the motor 12 based on the temperature of the FET 25a. Here, the current detection sensor 23 and the temperature sensor 24 are arranged in the operation panel 4 together with the control unit 20. As described above, by detecting the temperature of the motor 12 based on the temperature of the FET 25a disposed in the operation panel, compared to a configuration in which the temperature of the motor 12 disposed outside the operation panel 4 is directly detected,
Wiring and waterproof structure are simplified.

The control unit 20 includes an alarm 7, a display unit 5, and a PWM drive circuit 25 using an FET 25a.
And a storage unit 26 composed of a nonvolatile memory for storing various control data, a clutch-on solenoid 27, a read-out unit 28, and other input / output units. P
The motor 12 is connected to the WM drive circuit 25. Note that a mechanical breaker may be provided between the PWM drive circuit 25 and the motor 12. If a mechanical breaker is provided, a fail-safe function can be performed in the event of a runaway of the control unit 20 or a trouble that cannot be solved only by power control.

As shown in FIG. 4, the storage unit 26 has a display data storage area 30 for storing display data such as shelf positions.
A learning data storage area 31 for storing learning data indicating the relationship between the actual yarn length and the spool rotation speed; and a first storage area for storing a maximum duty ratio DTU according to the temperature of the motor 12 used in the PWM drive circuit 25. A duty table storage area 32, a second duty table storage area 33 for storing a maximum duty ratio DSU corresponding to a shift speed used in the PWM drive circuit 25, and a data storage area 34 for storing various data are provided. I have.

The second duty table storage area 33 stores, for example, 50% for the first and second speeds on the low speed side, 80% for the third and fourth speeds, the fifth highest speed in the supply voltage of the external power supply 40, and the boosted state. In the sixth speed, the maximum duty ratio DSU of 100% is stored. In this way, the maximum duty ratio DSU is set to increase as the shift speed increases.

The read unit 28 stores the actually set duty ratio D of the PWM drive, the maximum duty ratios DTU and DSU read from the two duty table storage areas 32 and 33, the set shift speed SC, and the like. It is memorized. Further, the electric reel incorporates a switching unit 41 and a booster circuit 42 controlled by the control unit 20.
The switching unit 41 switches a route for transmitting power supplied from the external power supply 40 such as a battery to the PWM drive circuit 25.
Specifically, the switching unit 41 sends the supply voltage of the external power supply 40 to the PWM drive circuit 25 as it is, or boosts the supply voltage via the booster circuit 42 to increase the supply voltage via the booster circuit 42 according to a command from the control unit 20. Switch to send to.

Is connected, initialization is performed in step S1 of FIG. Here, the water depth display is set to “0”, various flags are reset, and the display mode is set to the mode from above.

In step S2, a display process is performed. In the display processing, various displays such as a water depth display are performed. Here, when the mode is from the top, the water depth LN from the top is displayed on the water depth display portion 5a, and when the mode is from the bottom, the distance S from the water bottom is displayed. When the shelf position is set, the upper shelf position TU is displayed on the shelf memo display section 5d when the mode is set from the top, and the bottom shelf position TS is displayed when the mode is set from the bottom.

In step S3, it is determined whether a key input has been made by operating various buttons of the operation key section 6. When a key input is made in step S3, the process proceeds to step S7, and a key input process shown in FIG. 6 is performed. In step S4, it is determined whether the spool 10 has rotated. This determination is made based on the output of the spool rotation sensor 21. If it is determined that the spool 10 is rotating, the process proceeds from step S4 to step S8, and it is determined whether the relay switch 22 is on. The relay switch 22 is provided with the yarn length measuring device 15 and the yarn length and spool 1.
It is turned on only when learning the relationship with the 0 rotation position.
If the relay switch 22 is turned on, the process proceeds to step S9, and proceeds to a learning mode process for learning the relationship between the rotation of the spool 10 and the yarn length. In the learning mode process, map data MAP (N) indicating the relationship between the yarn length (water depth) LN and the rotation data N of the spool 10 is calculated and stored in the learning data storage area 31. If the relay switch 22 is not turned on, the process shifts to step S10 to execute each mode process (FIG. 7).

In step S5, it is determined whether or not the voltage supplied to the motor 12 has been boosted by the switching unit 41 and the boosting circuit 42. If it is determined that the pressure has been increased, the process proceeds from step S5 to step S11, and the motor load confirmation processing shown in FIG. 8 is executed. In step S6, it is determined whether another command has been issued. When another command is issued, the process proceeds from step S5 to step S12,
Perform other processing according to the command.

In the key input process of step S7 shown in FIG. 6, first, in step S21, it is determined whether or not the motor on / off button PB has been pressed. In step S22, it is determined whether or not the upper switch of the acceleration / deceleration switch SK has been pressed. In step S23, it is determined whether or not the down switch of the acceleration / deceleration switch SK has been pressed. In step S24,
Whether the shelf memo button TB has been pressed, the bottom memo button SB has been pressed, a key input of the bottom memo button SB for a long time (for example, 3 seconds or more) has been performed, or the bottom memo button SB and the shelf memo button TB have been simultaneously The operation button has been pressed,
It is determined whether another key input has been performed, such as whether the key input has been performed.

When the motor on / off button PB is pressed in step S21, the process proceeds to step S30. In step S30, it is determined whether or not the motor 12 is off. If the motor 12 has already been turned on, the process proceeds to step S31, and the motor 12 is stopped. If the motor 12 is off, the process proceeds to step S32 and the motor 1
Turn on 2. In step S33, the gear position is increased by the time during which the motor on / off button PB is pressed. The gear stage SC at this time is stored in the reading unit 28 and displayed on the speed display unit 5e. Step S
At 34, the motor 12 is increased in speed by performing a process of increasing the duty ratio D (hereinafter, a process of increasing the duty ratio). In the process of increasing the duty ratio, the maximum duty ratio DTU corresponding to the temperature T detected by the temperature sensor 24, the maximum duty ratio DSU corresponding to the shift speed SC, the current value I detected by the current detection sensor 23, the spool rotation sensor The duty ratio D is increased in consideration of the number of revolutions of the spool 10 detected by 21 and the like. If the upper switch of the acceleration / deceleration switch SK is pressed in step S22, the process proceeds to step S35.
Move to In step S35, the shift speed is increased by the time during which the motor on / off button PB is pressed. The gear stage SC at this time is stored in the reading unit 28 and displayed on the speed display unit 5e. In step S36, it is determined whether or not the shift stage SC is the sixth speed. If the sixth speed is the sixth speed, the switching unit 41 is switched in step S38 to boost the voltage by the booster circuit 42. In step S37, the process for increasing the duty ratio is performed in step S37, and the speed of the motor 12 is increased.

In step S23, the acceleration / deceleration switch S
When the down switch of K is pressed, the process proceeds to step S39. In step S39, the gear position is reduced by the time during which the motor on / off button PB is pressed. The gear stage SC at this time is also stored in the reading unit 28 and is displayed on the speed display unit 5e. In a step S40, it is determined whether or not the gear stage SC is the fifth speed. If the fifth speed is the fifth speed, the switching unit 41 is switched in the step S42 to change
The supply voltage of 0 is supplied to the PWM drive circuit 25 in a state where the voltage is not boosted, and if the speed is 4th or lower, a process of reducing the duty ratio D in step S41 (hereinafter referred to as a process of reducing the duty ratio) is performed. Slow down. In the process of reducing the duty ratio, the duty ratio D is reduced in consideration of the maximum duty ratio DSU corresponding to the shift speed SC, the rotation speed of the spool 10 detected by the spool rotation sensor 21, and the like.

If another key input has been made in step S24, the flow shifts to step S43 to perform another key input processing corresponding to the pressed key. For example, when the shelf memo button TB is pressed, the water depth LN at this time is stored in the display data storage area 30 as the upper shelf position TU, and a value obtained by subtracting the current water depth LN from the water depth S at the bottom is taken as the bottom shelf position SU. Is stored in the display data storage area 30. When the bottom memo button SB is pressed, the water depth LN at this time is stored in the display data storage area 30 as the water depth S of the water bottom. When the bottom memo button SB is pressed for 3 seconds or more, the display mode is switched from top to bottom, and when the jig button IB is pressed, the operation mode is switched to jig mode.

In each mode processing shown in FIG. 7, first, in step S50, it is determined whether or not the rotation of the spool 10 is the rotation in the line payout direction. This determination is made by the spool rotation sensor 21.
Is performed depending on which reed switch is turned on first. When it is determined that the rotation direction of the spool 10 is the line payout direction, the process proceeds to step S51. In step S51,
The rotation data N is increased. In step S52, the water depth LN is obtained from the increased rotation data N by using the map data MAP (N). Thereby, the water depth display is updated in the display processing. In step S53, it is determined whether or not the calculated water depth LN matches the upper shelf position TU. Step S
At 54, it is determined whether the mode is another mode. If the mode is not another mode, each mode process is ended and the process returns to the main routine.

When the water depth LN coincides with the upper shelf position TU, the process moves from step S53 to step S55. Step S
At 55, a shelf alarm is output from the alarm 7. In step S56, the solenoid 27 is turned on to turn on the clutch. In the case of another mode, the process shifts from step S54 to step S57 to execute another mode process. On the other hand, if it is determined in step S50 that the rotation direction of the spool 10 is the line winding direction, the process proceeds to step S60. In step S60, the rotation data N is reduced. In step S61, the water depth LN is obtained from the increased rotation data N using the map data MAP (N). Thereby, the water depth display is updated in the display processing.

In step S62, it is determined whether or not a subtraction value obtained by subtracting the calculated water depth LN from the water depth S at the bottom matches the bottom shelf position TS. If the subtraction value matches the bottom shelf position TS in step S62, the process proceeds to step S65. In step S65, a shelf alarm is output from the alarm 7. In step S66, the motor 12 is turned off. In step S63, it is determined whether or not the calculated water depth LN is equal to or smaller than a subtraction value obtained by subtracting a predetermined length SL from the rim stop position FB. The hull stop position FB is a position set so that the device is returned to the hand. The predetermined length SL is
The length is appropriately set so as to easily stop the motor 12 at the hull stop position FB, and is 2 m here. If the water depth LN is equal to or less than the subtraction value obtained by subtracting the predetermined length SL from the hull stop position FB in step S63, it is determined in step S67 whether the voltage of the power supplied to the motor 12 has been increased. If it is determined in step S67 that the voltage has been boosted, the switching unit 41 is switched, and the boost is released. When the boosting is released, the shift stage SC changes from the sixth speed to the fifth speed, and the maximum duty ratio DT corresponding to the fifth speed is set.
U and DSU are two duty table storage areas 3
2 and 33 are read out to the reading unit 28.

In step S64, the calculated water depth LN
Is determined to match with the hull stop position FB. If the water depth LN matches the hull stop position FB, step S69 is performed.
Move to In step S69, a rim alarm is output from the alarm 7. In step S70, the motor 12 is turned off. In the load confirmation process shown in FIG.
At 80, the temperature T of the FET 25a is read by the temperature sensor 24. In step S81, it is determined whether or not the temperature T has exceeded an allowable temperature TM allowed at the time of boosting. In step S82, the current value I of the current detection sensor 23 is read, and in step S83, it is determined whether the current value I exceeds the allowable current value IM at the time of boosting. When the temperature T exceeds the allowable temperature TM and when the current value I exceeds the allowable current value IM, the switching unit 41
Is switched to release the boost. When the boosting is released, the shift stage SC is changed from the sixth speed to the fifth speed, and the maximum duty ratios DTU and DSU corresponding to the fifth speed are read out from the two duty table storage areas 32 and 33 to the reading unit 28. Here, the rotation speed of the motor 12 for rotating the spool 10 is set to a maximum duty ratio D of six stages.
It can be changed based on the SU. The power is supplied to the motor 12 by the supply voltage of the external power supply 40 up to the fifth speed, and the power is supplied to the motor 12 by boosting the voltage by the booster circuit 42 at the sixth speed. These changes in the first to sixth speeds can be performed only by operating the acceleration / deceleration switch SK.
When the speed changes from the fifth speed to the sixth speed, the control unit 20 automatically issues a command to the booster circuit 42 to boost the voltage, and the switching unit 41
Switch. By operating the acceleration / deceleration switch SK in this manner, the acceleration / deceleration with the supply voltage of the external power supply 40 (1 to 5)
In addition to the speed, the state in which the voltage is boosted (sixth speed) can be generated. For this reason, the angler can use the pressurized state (sixth speed) as one of the normal winding speeds without performing a difficult operation or determination.

When the load applied to the motor 12 is large and the boosted state (sixth speed) continues, the motor driving element F
Although there is a possibility that the ET 25a or the like may be damaged, here, the load confirmation processing is performed in step S11, and when the motor 12 is likely to be overloaded, the boost is automatically released (step S84). Therefore, damage to the motor 12 and the like due to overload can be suppressed.

In this case, the fishing line is moved to the hull stop position FB.
If it is the sixth speed (boosted state) when it is wound up to 2 m (SL) before, the control unit 20 releases this (step S68). Therefore, it is 2 times larger than the hull stop position FB.
The hoisting speed is slowed down by m, and it becomes easy to stop the hoisting at the rim stop position FB. [Other Embodiments] (a) The temperature of the motor may be directly detected. In this case, the wiring and the waterproof structure are complicated as compared with the above embodiment. Further, the temperature of the motor may be detected based on the temperature of the current detection sensor. (B) Instead of a configuration in which the motor is controlled by the current, the motor may be controlled by the voltage. For example, a DC-DC converter using an FET may be arranged between the motor and the control unit, and a voltage corresponding to a load may be supplied from the DC-DC converter to the motor. (C) The motor is not limited to a DC motor, but may be an AC motor or a stepping motor.

[0037]

According to the present invention, by operating the acceleration / deceleration switch, it is possible to generate a state in which the voltage is boosted in addition to the acceleration / deceleration with the supply voltage of the power supply. It is possible to use the pressurized state as one of the normal winding speeds without performing any operation or judgment. For this reason, compared with the case where the boosting switch is provided separately from the speed-up / down switch, it is possible to save the angler's judgment and the operation of the angler regarding the generation of the boosted state.
