2. Description of the Related Art Generally, an electric reel is a reel for driving a motor with electric power supplied from an external power supply via a cord, rotating a spool, and winding a fishing line. In this type of electric reel, when winding the fishing line at high speed or winding the fishing line on an empty spool,
For example, a booster circuit provided in a drive section of the motor is operated to boost the voltage supplied to the motor to increase the speed of the motor. By rotating the spool at high speed, the fishing line can be wound quickly. Further, since a large load is imposed on the boosting circuit in the above-described boosting state, a function for controlling the boosting state is provided in order to prevent burning of the boosting circuit.

[0003]

In a conventional electric reel, a boosted state is controlled by detecting a current value supplied to a motor under predetermined conditions. For example, when a current value of 12 A or more is detected, the boost state is released. However, even if the current value of 12 A is detected, for example, at the beginning of the start of boosting, the load may not actually be applied to the boosting circuit. In this case, the boosted state is canceled even though the possibility that the booster circuit is burned is low, so that the performance of the booster circuit cannot be fully utilized.

[0006] In this motor control device, by detecting the temperature indicating the direct load of the booster circuit, the control of the boosted state can be performed more accurately than in the case of detecting the current value. Here, for example, by setting a limit temperature at which the booster circuit is burned out as the temperature at which the boosted state is released, the performance of the booster circuit can be maximized.

The motor control device according to a second aspect of the present invention is the motor control device according to the first aspect, wherein the first boosting control means boosts the supply voltage to the motor when the temperature of the boosting circuit is within a predetermined temperature range. To a predetermined boosted state.
In this case, for example, by setting the rate of boosting for each predetermined temperature range, the boosting state can be changed stepwise for each temperature range.

[0008] The motor control device according to a third aspect of the present invention is the motor control device according to the first or second aspect, wherein the first boosting control means comprises:
When the temperature of the booster circuit exceeds a predetermined temperature, the boosted state is released. In this case, a function of releasing the boosted state of the motor when the temperature exceeds a predetermined temperature can be added. A motor control device according to a fourth aspect of the present invention is the motor control device according to any one of the first to third aspects, further comprising: a current value detection unit that detects a current value supplied to the motor; And a second boosting control means for controlling the boosting circuit. In this case, the temperature of the boosting circuit can be detected by the first boosting control means, and the current value supplied to the motor can be detected by the second boosting control means.

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 shifts from step S4 to step S8, and executes each mode process (shelf alarm process, shore alarm process, etc.).

In step S5, it is determined whether the motor 12 is turned on. If it is determined that the switch is turned on, the process proceeds from step S5 to step S9. In the acceleration / deceleration processing in step S9, 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 rotation speed data set for the current gear stage SC, and the duty ratio D is adjusted so that the two are matched. The rotation of the motor 12 that rotates the spool 10 is increased or decreased.

If the magnitude of the current value is equal to or larger than 12 A, the process shifts to step S54 to cancel the boost. When the magnitude of the current value is less than 12 A, the process shifts to step S53 to perform the boost control corresponding to the boost control condition table shown in FIG.

In step S6 shown in FIG. 6, it is determined whether another command has been issued. When another command is issued, the process proceeds from step S6 to step S12, and performs another process according to the command. In the key input process of step S7 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, whether the shelf memo button TB has been pressed, the bottom memo button SB has been pressed, the key input of the bottom memo button SB has been performed for a long time (for example, 3 seconds or more), the bottom memo button SB and the shelf memo button It is determined whether or not another key input such as simultaneous operation with TB or key input of the jig button IB has been performed.

In step S21, the power button PB
Is pressed, the process moves to step S30. Step S
At 30, it is determined whether or not the motor 12 is on. If the motor 12 is already on, step S
The process proceeds to 31 and the motor 12 is stopped. If the motor 12 is off, the process proceeds to step S32, and the motor 12 is turned on.

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 shift speed is increased. The gear stage SC at this time is stored in the reading unit 28 and is displayed on the speed display unit 5e in the display processing. In a step S41, it is determined whether or not the shift speed SC is the seventh speed.
1, the boosting circuit 42 boosts the supply voltage of the external power supply 40 and supplies the boosted voltage to the PWM 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 is reduced. 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 step S44, 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 S45 to change the PWM drive circuit 25 without increasing the supply voltage of the external power supply 40. To be supplied.

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. When the bottom memo button SB is pressed for 3 seconds or more, the display mode is switched from the top to the bottom, and when the jig button IB is pressed, the operation mode is switched to the jig mode.
