[Problems to be Solved by the Invention]

However, in fishing grounds, depending on the type of fish to be caught and the conditions of the fishing ground, the rotation speed of the motor may be changed rapidly or gradually. However, as in the case of the electric reel in Patent Document 1, when the rotational speed of the motor is adjusted by pressing the operating portion with the pressing force, it is desired to obtain a relationship between the pressing force and the amount of change in the rotational speed that is suitable for conditions such as fishing grounds. It is difficult. Furthermore, in the electric cord reel of Patent Document 1, since the change pattern of the rotational speed of the motor corresponding to the pressing force is constant, the relationship between the pressing force and the amount of change in the rotational speed cannot be changed.

Furthermore, for the jerk caused by the fish, the fisherman will transfer the force to the hand holding the reel, and the pressing force to press the operation part will tend to increase. However, in this case, the rotational speed and torque of the motor If it increases sharply, the fishing line will be cut off.

The object of the present invention is to change the relationship between the pressing force and the change amount of the output of the motor in the motor control device of the electric reel to a relationship suitable for conditions such as fishing grounds. [Means to solve the problem]

A motor control device for an electric cord reel according to one aspect of the present invention drives a reel rotatably mounted on the cord reel body by a motor, and includes: a pressing operation part, a memory part, a motor control means, and a mode Switch means. The push operation part is provided on the main body of the cord reel. The memory unit memorizes a first control mode in which the output of the motor is controlled according to the pressing force of the pressing operation part, and a second control mode in which the output of the motor corresponding to the pressing force is different from the first control mode. Complex control mode. The motor control means is to control the output of the motor according to the pressing force in any one of the plural control modes. The mode switching means is to switch the control mode of the motor control means from the plurality of control modes to other control modes.

In the motor control device of the electric cord reel, the control mode of the motor control means, for example, from the first control mode, the output to the motor corresponding to the pressing force can be different from the first control mode by means of the mode switching means. 2nd control mode switching. Thereby, the relationship between the pressing force and the amount of change in the output of the motor can be changed to a relationship suitable for conditions such as a fishing ground.

Preferably, the plurality of control modes include control modes in which the rate of increase or rate of decrease of the output of the motor corresponding to the pressing force is different from each other.

Preferably, the mode switching means switches the control mode of the motor control means by pressing the operation part and simultaneously operating the operation part. In this case, the control mode of the motor control means can be quickly and easily changed. [Effect of the invention]

According to the present invention, in the motor control device of the electric reel, the relationship between the pressing force and the amount of change in the output of the motor can be changed to a relationship suitable for conditions such as a fishing ground.

An electric cord reel 100 according to an embodiment of the present invention is, as shown in FIG. 1 , an electric cord reel driven by a motor with electric power supplied from an external power source. Furthermore, the electric line reel 100 has a water depth display function for displaying the water depth of the fishing rig according to the line discharge length or the line take-up length.

The electric line reel 100 mainly includes: a line reel body 1 that can be installed on a fishing rod, a reel 2 disposed inside the line reel body 1, and a motor 3 that rotates the reel 2 in the line winding direction, And the operation lever 4 for rotating the reel 2 arranged on the side of the reel body 1, and the meter case 5 for displaying the water depth.

The cord reel body 1 has a frame 6, a first side cover 7a covering one side of the frame 6, a second side cover 7b covering the other side of the frame 6, and a front cover of the frame 6. front cover not shown. In addition, inside the cord reel body 1, there are provided: an unillustrated uniform winding mechanism that operates in conjunction with the spool 2, and an unillustrated rotation transmission mechanism that transmits the rotation of the motor 3 and the operating lever 4 to the spool 2. institutions etc.

The spool 2 is rotatably attached to the cord reel body 1 between the first side cover 7a and the second side cover 7b. The motor 3 is arranged inside the drum 2 .

The operating lever 4 is rotatably supported on the lower center portion of the first side cover 7a. Furthermore, the clutch operating member 9 is disposed above the support portion of the operating lever 4 so as to be able to swing freely. The clutch operating member 9 is a member for conducting (ON) and disengaging (OFF) a clutch (not shown) provided between the motor 3 , the operating lever 4 , and the spool 2 .

The meter case 5 is disposed on the upper front side of the cord reel body 1 and is fixed to the first side plate 6 a and the second side plate 6 b constituting the frame 6 . In the upper part of the meter case 5, a display part 10 having a liquid crystal display is provided. On the rear side of the display unit 10, as shown in FIGS. 1 and 2, a first push operation part 11, a second push operation part 12, and a button protruding upward from the meter case 5 are arranged. 3 operation switches 13 (an example of an operation unit). In the present embodiment, the first and second pressing operation parts 11 and 12 are arranged offset from the center in the left-right direction toward the side opposite to the operation lever 4 . In addition, the first push operation part 11 and the second push operation part 12 are arranged adjacent to each other in the vertical direction. The three operation switches 13 are mainly used for various settings of the electric cord reel 100 . Inside the meter case 5, a control unit 21 (see FIG. 3 ) for performing various controls is accommodated.

The first and second push operation parts 11 and 12 respectively have pressure sensors 11a and 12a as shown in FIG. 3 . The pressure sensors 11a, 12a are members that output electrical signals corresponding to the levels of forces (hereinafter referred to as pressing forces) that press the first and second pressing operation parts 11, 12, and detect the magnitude of the pressing force. The output value is output as an electric signal to the motor control unit 22 of the control unit 21 described later.

As shown in FIG. 3 , the control unit 21 has a functional configuration including a motor control unit 22 for controlling the motor 3 and a display control unit 23 for controlling the display unit 10 . The motor control unit 22 is a motor drive circuit 24 that drives the motor 3 through PWM, and controls the driving of the motor 3 in response to the pressing operations of the first and second pressing operation units 11 and 12 .

The motor control unit 22 controls the output of the motor according to the pressing force of pressing the first pressing operation unit 11 or the second pressing operation unit 12, including the first control mode, the second control mode, and the third control mode. Any one of the control modes controls the output of the motor. The motor control unit 22 increases the output of the motor 3 (hereinafter referred to as motor output) according to the pressing force while the first pressing operation unit 11 is being pressed in the first control mode and the second control mode, and increases the output of the second pressing operation unit 11 according to the pressing force. While the pressing operation part 12 is being pressed, the output of the motor is reduced according to the pressing force. Furthermore, the motor control unit 22 maintains the motor output when the pressing of the first pressing operation unit 11 or the second pressing operation unit 12 is stopped in the first control mode and the second control mode.

In the first control mode and the second control mode, the greater the pressing force, the greater the increase or decrease in the output of the motor. In addition, the first control mode and the second control mode make the motor output corresponding to the pressing force different from each other. Specifically, in the first control mode and the second control mode, the increase rate or decrease rate of the motor output corresponding to the pressing force is different from each other.

In this embodiment, the motor output is controlled in Nmax+1 stages from 0 to Nmax, so that the motor output corresponding to each stage is set. The motor output is, for example, the rotation speed of the motor 3 and the torque of the motor 3 . Stage 0 is a state where the motor 3 is stopped, and stage Nmax is a state where the motor 3 is driven with the maximum output.

For example, in FIG. 4 , the vertical axis shows the step increase number M and the step decrease number L of the motor output stage, and the horizontal axis shows the pressing force P. Also, the 1-point lock line C1 is a characteristic of the first control mode, and the 2-point lock line C2 is a characteristic of the second control mode.

As shown in FIG. 4, when the first push operation part 11 is pressed with the pressing force P1, the step increase number M1 in the first control mode is set larger than the step increase number M2 in the second control mode. Also, similarly, when the second push operation portion 12 is pressed with the pressing force P2, the number L1 of step reduction in the first control mode is set to be larger than the number L2 of step reduction in the second control mode.

In addition, in the third control mode, the motor 3 is driven only while the first pressing operation part 11 is being pressed. Also, in the third control mode, the greater the pressing force, the more the motor output increases.

To the control unit 21 , the first and second push operation units 11 and 12 and the operation switch 13 are connected. Furthermore, the control unit 21 is connected with the display unit 10 , the reel sensor 25 for detecting the rotational speed and the rotational direction of the reel 2 , and the memory unit 26 . The memory unit 26 is, for example, a non-volatile memory, and stores various setting information of the electric reel 100 such as information on the position of the shed (depth of the fish migration layer) and information on the stop position of the ship's edge. In addition, in the storage unit 26, plural control patterns including the first control pattern, the second control pattern, and the third control pattern are stored.

When switching the control mode of the motor control unit 22 from among the plurality of control modes to another control mode, it is switched by, for example, a mode switching operation of the operation switch 13 . Here, the mode switching operation of the operation switch 13 is, for example, continuous pressing and long pressing of the operation switch 13 , and is not particularly limited. Furthermore, when one of the first push operation part 11 and the second push operation part 12 and the operation switch 13 are operated simultaneously, the control mode of the motor control part 22 may be switched to another control mode. Also, when there are three or more control modes, the control modes may be switched in a determined order each time the operation switch 13 is operated, and may be arbitrarily selected from a plurality of control modes.

Also, the control mode of the motor control unit 22 when the power supply of the electric cord reel 100 is turned on may be selected from a plurality of control modes, and the control mode selected in the previous use may be stored in the memory. 26, it is also possible to continue the control mode selected last time. And, the switch to the third control mode is only when the motor 3 is not driven, that is, when the motor output is 0, it can be switched by the above-mentioned operation method.

<Mode Switching Process> Next, the mode switching process for switching the control mode of the motor control unit 22 from the plurality of control modes to another control mode will be described with reference to FIG. 5 . Also, the mode switching process is executed by the control unit 21 .

In step S1, it is judged whether or not a mode switching operation is performed. If it is determined that the mode switching operation has been performed, the process proceeds to step S2. If the mode switching operation is not performed, the mode switching process is not executed.

In step S2, it is judged whether the 3rd control mode is selected by the mode switching operation. If the 3rd control mode is not selected, it will move to step S3. In step S3, the control mode of the motor control unit 22 is switched to the control mode selected in step S1. Also, when the control modes are switched in a determined order every time the operation switch 13 is operated, the current control mode is switched to the next control mode. If it is determined in step S2 that the third control mode is selected, the process proceeds to step S4.

In step S4, it is determined whether or not the motor 3 is driven. That is, it is judged whether or not the motor output is 0. If it is determined that the motor 3 is driven, the mode switching process is not executed. If it is determined that the motor 3 is not driven, the process proceeds to step S5, and the control mode of the motor control unit 22 is switched to the third control mode.

<Motor Control Process> Next, an example of the flow of the motor control process performed by the motor control unit 22 of the control unit 21 when the power supply of the electric cord reel 100 is ON will be described with reference to FIG. 6 . Here, for example, the motor 8 is controlled by PWM, and the maximum output is 100% duty ratio. The motor output is, for example, the rotational speed of the motor 8. Here, when a load acts on the motor 8 to lower the rotational speed of the spool 2, it is feedback-controlled so as to maintain a predetermined rotational speed.

And here, a lower limit value and an upper limit value (for example, a lower limit value of 30 grams and an upper limit value of 2 kg) of the pressing force output from the pressure sensors 11 a and 12 a are set. Furthermore, in addition to dividing the range of the lower limit value and the upper limit value into arbitrary steps (for example, 31 equal divisions), the number of increases and decreases in motor output steps corresponding to each step is also set.

In step S11, it is determined whether or not the first pressing operation portion 11 is pressed with a pressing force P1 of 30 g or more. Specifically, for example, by detecting the output from the pressure sensor 11 a of the first push operation part 11 , it is determined whether or not the first push operation part 11 has been pressed with a pressing force P1 of 30 g or more. If it is determined that the first pressing operation part 11 is pressed with the pressing force P1 of 30 g or more, the process proceeds to step S12. When only the output of the pressing force P1 of less than 30 g is detected, it is regarded as not being pressed in order to avoid an erroneous operation, and the output is ignored. In addition, here, for example, a resistive film type pressure sensor is used, and a circuit is configured such that an output voltage is proportional to a pressing force.

In step S12, it is determined whether or not the pressing force P1 is less than 2 kg. When the pressing force P1 is more than 2 kg, the process proceeds to step S21, and the motor output stage N is set to Nmax. Thereafter, the process moves to step S19 to maintain the motor output stage Nmax, that is, the motor output is maintained at the maximum output. If the pressing force P1 is less than 2 kg in step S12, the process proceeds to step S13. Also, in the state where the motor output is maintained at the maximum output, when the first pressing operation part 11 is pressed by the pressing force P1 of 2 kg or more, it moves to step S21, but because the motor output has been maintained at the maximum output, So as a result, the motor output is continuously maintained at the maximum output.

In step S13, the current motor output phase N is read, and the process proceeds to step S14.

In step S14, it is judged whether the current motor output stage N is Nmax. If the motor output stage N is determined to be Nmax, the motor control process is not executed because the output cannot be increased further. That is, the motor output is directly maintained by the motor output stage Nmax. If it is determined that the motor output stage N is not Nmax, the process proceeds to step S15.

In step S15, the step increase number M of the motor output step corresponding to the pressing force P1 is read from the storage unit 26, and the process proceeds to step S16. The step increase number M here is the step increase number corresponding to the range of the pressing force P1 in the control mode of the motor control unit 22 . That is, as shown in FIG. 4, for example, if the current control mode is the first control mode, the step increase number M1 that is larger than the step increase number M2 of the second control mode is read from the storage unit 26 with reference to the characteristic C1. .

In step S16, it is judged whether or not Nmax is less than the current motor output stage N by adding the step increase number M. When it is less than Nmax, it moves to step S17.

In step S17, the motor output phase obtained by adding the step increase number M to the current motor output phase N is set as a new motor output phase N. Specifically, for example, when the first pressing operation part 11 is pressed with a pressing force P1 of 300g to 400g in the motor output state of the motor output stage "5", if the current control mode is the first control mode, Referring to the characteristic C1, add the step increase number "M1" (for example, "20") corresponding to the range of the pressing force P1 in the first control mode, and set the motor output stage to "25". And, if the current control mode is the second control mode, refer to the characteristic C2, add the step increase number "M2" (for example, "5") corresponding to the range of the pressing force P1 in the second control mode, and set the motor output stage as "10". Then, it moves to step S18.

In step S18, for example, after waiting for 0.5 seconds, the process proceeds to step S19, and the current motor output stage N is maintained in step S19.

In step S16, if the step increase number M is added to the current motor output stage N and it is determined that it is greater than Nmax, the process proceeds to step S20, and the motor output stage is set to Nmax-1 of the next stage. That is, as long as the pressing force P1 toward the first pressing operation portion 11 does not exceed 2 kg, the motor output stage does not become Nmax. Then, it moves to step S18.

In step S11, if it is determined that the first pressing operation portion 11 has not been pressed with the pressing force P1 of 30 g or more, the process proceeds to step S22.

In step S22, it is determined whether or not the second pressing operation portion 12 has been pressed with a pressing force P2 of 30 g or more. Specifically, similarly to the first push operation portion 11, by detecting the output from the pressure sensor 12a of the second push operation portion 12, it is determined whether the second push operation portion 12 is pressed by a pressing force P2 of 30 g or more. press. If it is determined that the second pressing operation portion 12 is pressed with the pressing force P2 of 30 g or more, the process proceeds to step S23. When only an output of about 30 g or less of the pressing force P2 is detected, it is regarded as not being pressed in order to avoid an erroneous operation, and this output is ignored. In this case, when the motor 3 is driven by the motor output stage "1" or higher, the current motor output stage is maintained.

In step S23, it is judged whether the current motor output stage N is "1" or more. That is, it is determined whether or not the motor 3 is driven. If the motor output phase N is "0", that is, if the motor 3 is not driven, the operation of the second push operation portion 12 for output reduction is meaningless, so the motor control process is not executed. If it is judged that the motor output stage N is "1" or more, the process proceeds to step S24.

In step S24, it is determined whether or not the pressing force P2 is less than 2 kg. When the pressing force P2 is more than 2 kg, the process moves to step S31, and the current motor output stage N is set to "0". That is, the drive of the motor 8 is stopped. In step S24, if it is determined that the pressing force P2 is less than 2 kg, the process proceeds to step S25.

In step S25, the current motor output stage N is read, and the process moves to step S26.

In step S26, the step reduction number L of the motor output step corresponding to the pressing force P2 is read from the storage unit 26, and the process proceeds to step S27. The step reduction number L here is the step reduction number corresponding to the range of the pressing force P2 in the control mode of the motor control unit 22 . That is, as shown in FIG. 4 , for example, if the current control mode is the first control mode, the step reduction number L1 larger than the step reduction number L2 of the second control mode is read from the storage unit 26 .

In step S27, it is judged whether the subtraction of the step reduction number L from the current motor output stage N is "1" or more. If "1" or more, it moves to step S28. If it is less than "1", go to step S30 to set the motor output stage N to "1" and go to step S29.

In step S28, the motor output stage obtained by subtracting the step reduction number L from the motor output stage N is set as a new motor output stage N. Specifically, for example, when the second pressing operation part 12 is pressed with a pressing force P2 of 300g to 400g in the motor output state of the motor output stage "25", if the current control mode is the first control mode, With reference to the characteristic C1, the step reduction number L1 (for example, "20") corresponding to the range of the pressing force P2 in the first control mode is subtracted, and the motor output step is set to "5". And, if the current control mode is the second control mode, refer to the characteristic C2, subtract the step reduction number L2 (for example, "5") corresponding to the range of the pressing force P2 in the second control mode, and set the motor output step to "20 ". Then, it moves to step S29.

In step S29, for example, after waiting for 0.5 seconds, the process proceeds to step S19, and the current motor output stage N is maintained in step S19.

In the electric cord reel 100 having the above-mentioned configuration, the control mode of the motor control unit 22 can be changed, for example, from the first control mode to the motor output corresponding to the pressing force by the mode switching means, which is different from the first control mode. 2 control mode switching. Thus, the step increase number M read in step S15 and the step decrease number L read in step S26 are read out corresponding to the control mode. That is, the relationship between the pressing force and the change amount of the motor output can be changed to a relationship suitable for conditions such as a fishing ground by means of mode switching.
