Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric reel, and more particularly to an electric reel for detecting a temperature and adjusting a usable range of a motor based on the detected temperature.

[0002]

2. Description of the Related Art An electric reel is known as a reel mounted on a fishing rod. The electric reel can rotate a spool around which a fishing line is wound by a handle and a motor. If the motor-on switch is pressed after the fishing line is drawn out to a predetermined depth, the spool is rotated in a line winding direction by a motor.

[0003] In this type of electric reel, continuous operation under a high load may be forced depending on the target fish. Therefore, a motor and a circuit for driving the spool, a motor driving element and the like are prevented from burning out. Countermeasures are important. One of the measures is disclosed in Japanese Patent Application No. 08-233990. Here, the electric motor is controlled within a predetermined power range according to the temperature accompanying the heat generated by the rotation of the electric motor detected by detecting the temperature of the motor drive element and the like. Specifically, different maximum duty ratios are set depending on the temperature range, and the power supplied to the motor is controlled according to the temperature to suppress the temperature of the motor or the like from rising.

[0004]

In recent electric reels, a plurality of stages (first speed, second speed,...) Are provided, and a changer can change a stage to obtain a desired winding speed. Many of them have been changed. In the example of the above publication, 50% at the first to third speeds, and 65% at the fourth to sixth speeds.
The maximum duty ratio is set to 80% for the 7th and 8th speeds, and to 100% for the 9th speed. Then, a speed display section is provided on a display section that can be visually recognized by the angler so that the angler can know where the current gear is among the nine shift speeds.

However, since the maximum duty ratio changes depending on the temperature as described above, when the temperature rises, even if some of the nine shift speeds are selected, the high speed shifts are commensurate with the selected shift speed. The winding speed cannot be maintained.
That is, when the maximum duty ratio is limited to 50% beyond a certain temperature, even if the sixth speed or the seventh speed is selected, the duty ratio can be increased only to 50%, so that the selected stage is met. In some cases, the speed cannot be increased to the winding speed. In such a case, the angler would not be able to understand the cause because the angler did not know that the hoisting speed was high even though the desired gear was selected. Further, at this time, regardless of the selection of the shift speed, the hoisting speed fluctuates due to the maximum duty ratio corresponding to the factor of the temperature that the angler cannot recognize, and the intention of the angler is reflected on the hoisting speed of the electric reel. Will be gone.

An object of the present invention is to provide an electric reel which monitors temperature and suppresses burnout of a motor or the like, and which can provide necessary information to an angler and reflect the intention of the angler. It is in.

[0007]

An electric reel according to a first aspect of the present invention includes a reel body, a spool, an electric motor, a temperature detecting unit, a control unit, and a display unit. The spool is rotatably supported by the reel body. The motor rotates the spool. The temperature detecting means detects a temperature due to heat generated from the motor. The control unit adjusts the usable range of the motor based on the temperature detected by the temperature detecting unit. The display unit displays a usable range of the motor.

Here, the usable range of the motor determined by the amount of electric power supplied to the motor and the like is set in advance based on the temperature detected by the temperature detecting means, and the control unit can use the motor in accordance with the temperature. Adjust the range. For this reason, as the temperature increases, the usable range of the motor decreases,
It is possible to prevent the motor and the motor drive element from being overheated, which may cause burnout.

Then, in order to notify that the temperature rises and the usable range of the motor is narrowed, or to inform that the temperature is lowered and the usable range of the motor is widened, the motor usable range is displayed on the display unit. It is displayed. This allows the angler to know the range of motors that can be used now, for example, in the form of selectable gears and the maximum possible hoisting speed. Specifically, by displaying the currently selectable gear position on the display unit or displaying the maximum hoisting speed that can be currently increased, the angler can be notified of information on the motor usable range to the angler. Tell Then, the angler obtains this information and selects the hoisting speed as far as possible at present,
The angler's intention is reflected in the winding speed of the electric reel.

As described above, in the electric reel for protecting the motor or the like by monitoring the temperature, when the usable range of the motor is changed based on the temperature, the change is notified to the angler. If the winder does not go up, it will not be confused, and since the hoisting speed is selected within the range currently available, the intention of the angler is reflected on the electric reel.

The electric reel according to a second aspect of the present invention is the electric reel according to the first aspect, wherein the control unit adjusts a usable range of the motor by changing an upper limit value of electric power supplied to the motor.

Here, the control unit changes the upper limit value of the electric power supplied to the motor based on the temperature detected by the temperature detecting means. As a result, if the upper limit is limited when the temperature rises, it is difficult to reach a state where the motor or the like may be burned out, and the burning of the motor or the like can be suppressed without stopping the electric hoisting as much as possible. Can be.

An electric reel according to a third aspect of the present invention is the electric reel according to the first or second aspect.
In the electric reel described in (1), the display unit displays the usable range of the motor by indicating a usable stage among a plurality of stages based on the rotation speed of the motor.

This electric reel has a plurality of steps based on the rotation speed of the motor, and the display section shows the steps that can be used among them. This allows the angler to recognize the currently available stages and to select the stage corresponding to the desired winding speed from these stages. Therefore, the angler no longer selects a stage corresponding to the rotation speed of the motor that cannot be used because the temperature has risen, and the motor is turned at a speed corresponding to the reasonable stage selected by the angler, The winding speed will match the intention.

According to a fourth aspect of the present invention, in the electric reel according to the third aspect, each of the plurality of stages has an upper limit value of electric power supplied to the motor.

Here, since each of the plurality of stages has an upper limit value, determining the range of usable stages according to the temperature means adjusting the usable range of the power supplied to the motor according to the temperature. Can be. That is, if the range of usable stages is determined according to the temperature, the upper limit value of the electric power supplied to the motor changes according to the temperature, whereby the usable range of the motor is adjusted. When the range of usable steps is displayed on the display unit, it indicates the usable range of the motor.

The electric reel according to the fifth aspect of the present invention is the electric reel according to the third or fourth aspect.
In the electric reel described in (1), the display further indicates the current row. The current stage is based on the rotational speed of the motor.

Here, the current stage is displayed on the display unit in addition to the display of the available stages. Thereby, the angler can recognize both the current gear and the changeable gear, and can easily grasp the state of electric winding of the electric reel.

The electric reel according to the sixth aspect of the present invention includes the electric reels according to the first to fifth aspects.
In the electric reel according to any one of the above, the temperature detecting means detects a temperature of a motor driving element that drives the motor.

[0020] The electric reel according to the seventh aspect of the present invention includes the electric reels according to the first to fifth aspects.
In the electric reel according to any one of the above, the temperature detecting means detects a temperature of the motor.

The electric reel according to the eighth aspect of the present invention includes the electric reels according to the first to seventh aspects.
In the electric reel according to any one of the above, the control unit stops driving the motor when the temperature detected by the temperature detecting means exceeds a predetermined upper limit temperature.

Here, burnout of the motor and the like is suppressed by adjusting the operable range of the motor according to the temperature up to the predetermined upper limit temperature. Since the fear is extremely high, the driving of the motor itself is completely stopped. Because it is controlled in this way,
It is possible to suppress burnout of the motor and the like without stopping the electric hoisting as much as possible.

<Configuration of Control System> This electric reel is shown in FIG.
Has a control unit 20 as shown in FIG. The control unit 20
CPU, RAM, ROM,
A microcomputer including an I / O interface and the like is provided, and executes various control operations described later according to a control program. The control unit 20 is connected to various buttons (switches) of the operation 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, and a temperature sensor 24. Have been. The temperature sensor 24 includes a PWM drive circuit 25
The temperature of the motor 12 is indirectly detected by detecting the temperature of the FET 25a, which is a motor drive element used in the above. The temperature sensor 24 is arranged in the operation panel 4 together with the control unit 20. As described above, since the temperature of the motor 12 is detected by detecting the temperature of the FET 25a disposed in the operation panel, the temperature is compared with 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 read unit 28, and other input / output units. The PWM drive circuit 25 includes a motor 1
2 are connected.

As shown in FIG. 5, the storage section 26 has a display data storage area 30 for storing display data such as shelf positions.
And a learning data storage area 31 for storing learning data indicating the relationship between the actual yarn length and the spool rotation speed, the maximum duty ratio D _SU corresponding to the speed used by the PWM drive circuit 25, and the respective speeds. A duty table storage area 32 for storing a set winding speed (actually, a motor rotation speed) and a data storage area 34 for storing various data are provided.

For example, the duty table storage area 32 stores 50%,
A maximum duty ratio D _SU of 70% is stored in the 4th speed, 90% in the 5th speed, 100% in the 6th speed which is the highest speed in the supply voltage of the external power supply 40, and 100% in the 7th speed in the boosted state. In this manner, the maximum duty ratio _DSU is set to increase as the shift speed increases. The hoisting speed set for each gear stage SC is also stored in the duty table storage area 33. Here, the first gear is 40 m / min, and the second gear is 50 m / min.
The winding speed is set to m / min, the third speed is 60 m / min, the fourth speed is 70 m / min, the fifth speed is 80 m / min, the sixth speed is 90 m / min, and the seventh speed is 150 m / min.

The duty ratio D _SU and the winding speed are stored. Further, an upper limit gear SCU (described later) which is set in accordance with the temperature T of the FET 25a detected by the temperature sensor 24 is also stored in the read unit 28.

The electric reel incorporates a switching unit 41 and a booster circuit 42 controlled by the controller 20 (see FIG. 4). 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.

<Main Control of Electric Reel> Next, the control unit 2
The main control processing performed by 0 will be described with reference to the control flowcharts shown in FIGS.

When the external power supply 40 is connected to the electric reel, initialization is performed in step S1 shown in 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. Further, the initial value of the upper limit gear SCU is set to 7.

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 above, the water depth from above is displayed on the water depth display section 5a, and when the mode is from the bottom, the distance from the water bottom is displayed. When the shelf position is set, the upper shelf position is displayed on the shelf memo display section 5d when the mode is from the top, and the bottom shelf position is displayed when the mode is from the bottom.

In step S2, a hoisting speed display by displaying the current gear position and an available speed display by displaying a currently usable gear position are also performed.

In the hoisting speed display, the display is performed according to the gear stage SC. For example, when the current gear stage SC is the fifth speed, as shown in FIG.
a, 102a, 103a, 104a, and 105a are displayed on a liquid crystal display. When the current gear stage SC is the third speed, as shown in FIG.
Liquid crystal display is performed on three of 02a and 103a. In the available speed display, the display is performed according to an upper limit gear SCU which is the highest available gear, which will be described later. For example, in the case where the current upper gear SCU is the 7th speed, which is the highest speed,
As shown in FIGS. 10 and 11, all of the seven shiftable stage display portions 101b, 102b,..., 107b are displayed on a liquid crystal display. In the case where the current upper limit gear SCU is the third speed, as shown in FIG.
1b, 102b and 103b are displayed on a liquid crystal display. When the upper limit shift speed SCU is set to 0, it indicates that the motor 12 and the like are overheated and the motor 12 cannot be used. Not changeable gear stage display units 101b, 102
b,..., 107b all liquid crystal displays are turned off.

In step S3, it is determined whether a key input has been made by operating various buttons of the operation unit 6.
When a key input is performed in step S3, the process proceeds to step S8, and a key input process shown in FIG. 7 is performed.

In step S4, it is determined whether or not 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 S9, and executes each mode processing (shelf alarm processing, shipboard alarm processing, etc.).

In step S5, the gear position limiting process shown in FIG. 8 is performed. Here, first, at step S60, the temperature T of the FET 25a detected by the temperature sensor 24 is read, and then, at steps S61 to S67, it is determined whether or not the temperature T belongs to a predetermined temperature range. If the temperature T belongs to any of these, in any of steps S71 to S77, the upper limit gear SCU is reset. The upper limit gear SCU is a variable representing the fastest gear among selectable gears. For example, if the temperature T is lower than 50 °, the upper limit gear SCU is set to the seventh speed, and the temperature is 75 ° or higher and 80 ° or higher.
If it is less than ゜, the upper limit gear SCU is set to the first speed.
When the process proceeds to step S68, the current gear S
It is determined whether or not C exceeds the upper limit gear SCU,
When the shift speed SC exceeds the upper limit shift speed SCU,
In step S78, a process of lowering the shift speed SC so as to match the upper limit shift speed SCU is performed.

In step S6, it is determined whether the motor 12 is turned on. If it is determined that the switch is ON, the process proceeds from step S6 to step S10. In step S10, it is determined whether or not temperature T is equal to or higher than 80 ° which is the upper limit temperature at which motor 12 can be continuously used. If the temperature T is lower than the upper limit temperature 80 °, the process proceeds to step S12 to perform the acceleration / deceleration processing of the motor 11, and if the temperature T is higher than the upper limit temperature 80 °, the process proceeds to step S12 to stop the motor 12. Processing is performed.

In step S7, it is determined whether another command has been issued. When another command is issued, the process shifts from step S7 to step S13 to perform another process according to the command.

In the acceleration / deceleration process in step S11, the duty ratio D is increased or decreased to increase or decrease the speed of the motor 12. In this process, the current rotation speed of the spool 10 detected by the spool rotation sensor 21 is compared with the hoisting speed corresponding to the current gear stage SC.
The duty ratio D is adjusted to match the two, and the rotation of the motor 12 that rotates the spool 10 is increased or decreased. However, the duty ratio D is adjusted within a range that does not exceed the maximum duty ratio D _SU corresponding to the speed stage SC at that time. In this acceleration / deceleration process, it is determined whether the supply voltage is in a boosted state, that is, whether the booster circuit 42 boosts the supply voltage of the external power supply 40 and supplies the boosted voltage to the PWM drive circuit 25, If the speed is in the step-up state when the shift stage is lower than the sixth speed, the switching unit 41 is switched so that the supply voltage of the external power supply 40 is supplied to the PWM drive circuit 25 without stepping up.

In the motor stop process in step S12, as shown in FIG. 9, first, in step S80, the value of the upper limit gear SCU is set to 0. Thus, in the display processing of step S2, the shiftable stage display units 101b, 1
.., 107b are turned off (see FIG. 13), so that the angler can recognize that the motor 12 and the like are overheated and the motor 12 cannot be used. Then, in step S81, the motor 12
Is turned off.

In the key input process of step S8 shown in FIG. 7, it is first determined in step S21 whether or not the power 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, it is determined whether the shelf memo button TB has been pressed or the bottom memo button SB has been pressed.
Whether the bottom memo button SB has been keyed for a long time (for example, 3 seconds or more), the bottom memo button SB and the shelf memo button TB
It is determined whether or not another key input has been performed, such as whether the same operation as described above has been performed, whether the jig button IB has been keyed, or the like.

In step S21, power button PB
If is pressed, the process moves to step S30. In step S30, it is determined whether or not the motor 12 is in the ON state. If the motor 12 has already been turned on, the process proceeds to step S31, and the motor 12 is stopped. Motor 12
Is OFF, the process shifts to step S32 to determine whether or not the temperature T of the FET 25a detected by the temperature sensor 24 exceeds the upper limit temperature 80 °. Here, when the temperature T is higher than the upper limit temperature 80 °, the motor 12 is not turned on on the assumption that the risk of burning of the motor 12 and the like has not been solved. If the temperature T is lower than the upper limit temperature 80 °, the motor 12 is turned off in step S33.
N. When the motor 12 is turned on in step S33, the gear stage SC is initially set to the first speed, and electric hoisting by the motor 12 is started at the first hoisting speed.

In step S22, the acceleration / deceleration switch S
When the upper switch of K is pressed, the process proceeds to step S40. In step S40, the gear SC is increased.
The gear stage SC at this time is stored in the reading unit 28 and displayed on the speed display unit 5e. However, if the shift speed is already the seventh speed, which is the highest speed, the shift speed is not increased, and the process proceeds to step S23 by skipping steps S41 and S42 described later. In a step S41, it is determined whether or not the shift speed SC is the seventh speed. If the seventh speed is the seventh speed, the switching unit 41 is switched in a step S42, and the boosting circuit 42 boosts the supply voltage of the external power supply 40. PW
It is supplied to the M drive circuit 25.

In step S23, the acceleration / deceleration switch S
When the lower switch of K is pressed, the process proceeds to step S43. In step S43, the gear position SC is lowered.
The gear stage SC at this time is also stored in the reading unit 28 and is displayed on the speed display unit 5e. However, if the gear is already the first gear, which is the lowest gear, the gear is not reduced. In the step S44, it is determined whether or not the shift stage SC is the sixth speed.
In step 5, the switching unit 41 is switched so that the supply voltage of the external power supply 40 is supplied to the PWM drive circuit 25 without boosting.

If another key input has been made in step S24, the flow shifts to step S46 to perform another key input process corresponding to the pressed key. For example, when the shelf memo button TB is pressed, the water depth at this time is stored in the display data storage area 30 as the upper shelf position, and a value obtained by subtracting the current water depth from the water depth at the bottom is displayed as the bottom shelf position. 30. When the bottom memo button SB is pressed, the water depth at this time is stored in the display data storage area 30 as the water depth of the water bottom. Bottom memo button S
When B is pressed for 3 seconds or more, the display mode is switched from the top and from the bottom, and when the jig button IB is pressed, the operation mode is switched to the jig mode.

<Characteristics of Electric Reel> In this electric reel, an FET for protecting the motor 12 and the FET 25a is used.
The temperature T of the motor 25a is monitored, and the maximum duty ratio is changed by limiting the available gears according to the temperature T, and the electric power applied to the motor 12 is adjusted so as not to burn out due to overheating. In addition, the available gears are set finely in accordance with the temperature T (see FIG. 8), so that overheating is suppressed as much as possible without stopping the electric hoisting.

The above-described control for limiting the shift speeds that can be used in accordance with the temperature T is performed by looking at the shiftable speed display portions 101b, 102b,..., 107b of the speed display portion 5e. Can be recognized. This allows the angler to obtain information that, for example, it is impossible to increase the hoisting speed because the temperature is high, or that the hoisting speed can be increased to seven speeds because the temperature has decreased. it can. That is, the angler can know the range of the motor 12 that can be used now in the form of selectable gears. Then, the angler obtains this information and selects the winding speed (gear speed) within the range that is currently possible, so that the intention of the angler is reflected in the winding speed of the electric reel (the rotation speed of the motor 12). Will be.

For example, FIG. 10 shows the speed display unit 5 when the motor 12 is turned off and the electric hoist is not performed.
FIG. 5E is a state diagram of a shiftable stage display unit 10 shown in FIG.
All of 1b, 102b,..., And 107b are displayed on a liquid crystal display, and the angler can visually recognize that all the shift speeds (first to seventh speeds) can be used.

In FIG. 11, the column display units 101a, 102
, 105a, and all the variable speed display units 101b, 102b,..., 107b are displayed on a liquid crystal display. Therefore, the angler is currently performing electric hoisting at the fifth speed. It can be visually confirmed that the speed increase is possible up to the seventh speed.

In FIG. 12, the column display units 101a, 102
a and 103a are displayed, and three of the shiftable stage display portions 101b, 102b and 103b are displayed on a liquid crystal display. It can be visually recognized that the speed cannot be further increased for protection of the like.

In FIG. 13, the column display units 101a, 102
, 107a are not displayed, and all the shiftable stage display portions 101b, 102b,..., 107b are not displayed, so that the angler does not currently carry out the electric hoist and the motor 12 and the like are not displayed. It can be visually recognized that the electric winding cannot be performed in the overheated state (the motor 12 cannot be turned on).

[Other Embodiments] (A) The temperature of the motor 12 may be directly detected instead of the temperature of the FET 25a. In this case, the wiring and the waterproof structure are complicated as compared with the above embodiment. (B) The motor is not limited to a DC motor, but may be an AC motor or a stepping motor.

(C) In the above embodiment, the speed display section 5e
The information of the range of the currently selectable hoisting speed is transmitted to the angler by displaying the currently selectable gears, but instead, the maximum hoisting speed that can be increased at present is indicated by a numerical value. The information on the range of the hoisting speed that can be selected at present may be transmitted to the angler by displaying the information by, for example, the angler.

(D) As the temperature detecting means, in addition to directly detecting the temperature of the motor 12 and the FET 25a as a driving element as described above, the current heat generation amount is estimated from the time interval and the amount of current supplied. May be used

[0063]

According to the present invention, when the usable range of the motor changes based on the temperature, the change is displayed on the display unit to notify the angler, so that the angler cannot increase the winding speed due to overheating. Will not be confused, and the intention of the angler will be reflected on the electric reel by selecting the winding speed within the range currently available.
