Motor control device for electric reel

The present invention relates to a motor control device, and more particularly to a motor control device for an electric reel that can rotate a reel by a motor.

The electric reel that can be rotated by the motor when the reel is wound up includes a reel body, a reel that is rotatably supported by the reel body, and an operation for manually rotating the reel. A rod and an electric motor that drives the reel in a rolling direction. An operation panel is mounted on the upper surface of the reel body, and a display for performing water depth display and various input switches are provided.

In such an electric reel, electric winding can be performed at the time of recovery of the bait, and electric winding can be performed when the fish is hooked. When the fish is rolled up when the fish is hooked, the burden on the motor becomes large. In particular, when a large fish is hooked, a large current continues to flow to the motor for a long period of time, and the drive circuit of the motor and the motor, the motor drive element, and the like are heated and may be burnt.

In order to prevent the burning of such a motor and its driving element, it is known that the motor control device for the electric reel is supplied to the motor when the load (electric power) above the predetermined dangerous value of the motor becomes a dangerous condition for a predetermined time. The electric power falls below a predetermined value (for example, refer to Patent Document 1). Thereby, heating of a motor or the like can be suppressed.

In the motor control device of the conventional electric reel, in consideration of the regulation of the electric power supplied to the motor when the fish is hooked, the state in which the load of the motor is large continues until the predetermined depth of water reaches the bait, specifically the fish. It is controlled so as to suppress an increase in electric power supplied to the motor until the winding up is almost completed.

[Patent Document 1] Japanese Patent Laid-Open Publication No. 2000-139299

In the above-mentioned conventional structure, even if it is a dangerous condition, the current continues to flow although it falls below a predetermined value. This current is a state in which the motor is extremely low-speed or locked, and since it is almost heated, the motor temperature continuously rises to make the motor burnt.

In addition, if the power supplied to the motor is lowered, the reel cannot be driven by the expected winding speed, and the performance of the electric reel is lowered.

An object of the present invention is to prevent the motor from being burnt out without deteriorating the performance of the electric reel.

The motor control device for the electric reel according to the first aspect of the invention is a motor control device for an electric reel that drives a rotatable reel by a motor, and includes a rotation speed detecting unit, a load detecting unit, and an upper limit speed setting unit. And a first motor control unit. The rotation speed detecting portion detects the rotation speed of the reel. The load detecting unit detects the load acting on the reel by the current value. The upper limit speed setting unit is one that sets the rotational speed of the reel to the upper limit speed in the high and low complex stages. The first motor control unit is an upper limit speed that controls the motor to set the rotational speed of the reel to be set, and is continuously the first in a load state that is smaller than a predetermined first current value that is smaller than the maximum current value of the motor. When the reel is in the first state in which the reel is rotated by a predetermined first speed or lower, which is lower than the upper limit speed of the highest speed stage, the intermittent control for causing the ON/OFF intermittent current to flow to the motor is performed.

In this motor control device, the motor is normally controlled to be the upper limit speed set by the upper limit speed setting unit. The load is increased, and the higher load state is lower than the maximum current value, but the higher load state of the first current value or more continues for the first predetermined time, and the rotation speed of the reel falls to a predetermined first speed lower than the upper limit speed of the highest stage. In the first state, intermittent control is performed to flow an intermittent current (ON/OFF) to the motor. Thus, in a state of high load, by intermittently rotating the motor, the motor does not stop completely and the heat generation of the motor can be suppressed. Further, if the load is small, the motor can be raised to the set upper limit speed. Here, when the rotation of the motor is lowered by the high load to be locked, the low-speed rotation, or the like, the current flowing intermittently (ON/OFF) causes the excess current to flow to the motor, thereby suppressing the heat generation of the motor. Further, if the load is small, since the motor can be wound up by the set upper limit speed, the performance is not lowered and the burning of the motor can be prevented.

In the motor control device for the electric reel according to the second aspect of the invention, the first motor control unit is configured to increase the rotational speed of the reel to a second speed higher than the rotational speed of the first speed reel. The intermittent control is released, and the motor is controlled to be the upper limit speed of the set phase.

In this case, when the rotational speed of the motor is higher than the first speed in the first intermittent control, it is determined that the load acting on the motor reduces the start of rotation of the motor, and the intermittent control is released to the normal speed control.

In the motor control device for the electric reel according to the invention of the first aspect of the invention, the first motor control unit disconnects the motor when the first intermittent control is performed for a second predetermined time longer than the first predetermined time. On (OFF). In this case, even if the intermittent control is continuously performed for the second predetermined time longer than the first predetermined time, if the high load state in the first state is continued, the motor is turned off (OFF), so even if the high load state continues, The motor is also not easily burned.

The motor control device for an electric reel according to any one of the first to third aspects of the present invention, further comprising: a tension detecting portion for detecting a tension acting on the reel attached to the reel; and The upper limit tension setting unit that sets the tension of the fishing line to the upper limit tension of the high and low stages; and the upper limit tension of the tension applied to the line by the motor tension control, and flows to the ratio When the third state of the third predetermined time is continuous in the load state in which the maximum current value of the motor is smaller than the predetermined third current value, the second intermittent interruption of the ON/OFF current flows to the second discontinuity of the reel. a second motor control unit for control; and a control mode switching unit for switching the speed control generated by the first motor control unit and controlling the tension generated by the second motor control unit.

In this control device, since the speed control and the tension control can be switched, the most suitable control for the fishing object can be performed. In addition, when the third control is performed for the third predetermined time in the high load state in which the third current value flows in the case of the speed control, the ON/OFF interruption is performed. The current flows to the second intermittent control of the motor. As described above, in the tension control, when the motor is intermittently rotated in a high load state, the motor does not stop completely and the heat generation of the motor can be suppressed. Moreover, if the load is small, the motor can be rotated by the set upper limit tension. Moreover, the tension control is usually controlled by the wire diameter correction. In this case, in the case of the tension control, when the load is high, the state in which the motor is locked is frequently generated. Therefore, if the third predetermined time is short, the intermittent control time becomes long. Therefore, the third predetermined time is preferably determined by one or more digits longer than the first predetermined time in the speed control. Here, when the rotation of the motor is lowered by a high load and the rotation of the motor is interrupted (ON/OFF) during the lock and the low-speed rotation, the excess current does not flow to the motor, and the heat generation of the motor can be suppressed. Further, if the load is small, since the motor can be wound up by the set upper limit tension, the performance is not lowered for the tension control, and the burning of the motor can be prevented.

A motor control device for an electric reel according to a fifth aspect of the invention is a motor control device for an electric reel that drives a rotatable reel by a motor, and includes: a tension detecting unit, a load detecting unit, and an upper limit tension setting unit; Second motor control unit. The tension detecting portion detects the tension acting on the spool. The load detecting unit detects the load acting on the reel by the current value. The upper limit tension setting unit is one that sets the tension acting on the fishing line to the upper limit tension in the high and low plural stages. The second motor control unit controls the motor tension so that the tension acting on the fishing line becomes the upper limit tension at the set stage, and is lower than a predetermined third current value that is smaller than the maximum current value flowing to the motor. When the third state is the third predetermined time, the second intermittent control for flowing the intermittent current (ON/OFF) to the reel is performed.

In the motor control device, when the high load state in which the third current value flows is in the third state for the third predetermined time, the second intermittent control in which the intermittent current (ON/OFF) is caused to flow to the motor is performed. . Thus, in a state of high load, by intermittently rotating the motor, the motor does not stop completely and the heat generation of the motor can be suppressed. Moreover, if the load is small, the motor can be rotated by the set upper limit tension. Moreover, the tension control is usually controlled by the wire diameter correction. In this case, in the case of the tension control, when the load is high, the state in which the motor is locked is frequently generated. Therefore, if the third predetermined time is short, the intermittent control time becomes long. Therefore, the third predetermined time is preferably determined by one or more digits longer than the first predetermined time in the speed control. Here, when the rotation of the motor is lowered by a high load and the rotation of the motor is interrupted (ON/OFF) during the lock and the low-speed rotation, the excess current does not flow to the motor, and the heat generation of the motor can be suppressed. Further, when the load is small, since the motor can be wound up by the set upper limit tension, the performance is not lowered and the burning of the motor can be prevented.

In the motor control device of the electric reel according to the invention of the fourth aspect of the invention, the second motor control unit is in the fourth state in which the current flowing to the motor is the fourth current value equal to or lower than the third current value. The second intermittent control is released, and the motor tension control is set to the upper limit tension of the set stage.

In this case, when the current value is in the fourth state lower than the third current value in the second intermittent control, it is determined that the load acting on the motor is started to rotate, and the intermittent control is released to the normal tension control.

In the motor control device for the electric reel according to the seventh aspect of the invention, the second motor control unit performs the second intermittent control continuously for the fourth predetermined time shorter than the third predetermined time. The motor is turned off (OFF). In this case, even if the second intermittent control is continuously performed for the fourth predetermined time shorter than the set third predetermined time, and the high load state in the third state continues, the motor is turned off (OFF), so that the motor is turned off (OFF). The load state is not easily burned even if the motor continues.

In the motor control device for the electric reel according to the eighth aspect of the invention, at least one of the first and second motor control units is configured to turn off the ON time ratio (OFF). A short, intermittent current flows to the motor. In this case, in the first or second intermittent control, since the ON time of the intermittent current is short, the heat generation of the motor can be further suppressed.

The motor control device for an electric reel according to any one of the first to eighth aspects of the present invention, further comprising: at least one of the first and second motor control units, generating a phase corresponding to the setting a motor drive circuit for power-dependent modulation (PWM) of the duty ratio of the load; and a temperature detecting portion for detecting the temperature of the motor by the temperature of the motor drive circuit; and the first and second motor control units At least either, the motor is turned off (OFF) when the temperature of the motor drive circuit exceeds the first predetermined temperature. In this case, since the motor is turned off (OFF) by the temperature of the motor drive circuit corresponding to the increase in the heat generation temperature of the motor, the motor can be quickly turned off (OFF) without being affected by the environment of the fishing boat. .

The motor control device for an electric reel according to the invention of claim 10 is characterized in that, at least one of the first and second motor control units, the temperature of the motor drive circuit is a second predetermined temperature lower than the first predetermined temperature. In the above case, a discontinuous current having a shorter ON time than the OFF (OFF) time flows to the motor, and when the second predetermined temperature is not full, the ON time is longer than the OFF time. The current flows to the motor.

In this case, even if the current value is high, when the temperature of the motor drive circuit, that is, the start of the intermittent control at which the temperature of the motor is low, the ON time of the intermittent current is made to make the reel easily rotate, even if the temperature is high even after the intermittent control is continued. In this case, since the ON time can be shortened, the performance of the reel can be prevented from further decreasing, and the burning of the motor can be suppressed.

According to the present invention, in a state of high load, heat can be suppressed by intermittently rotating the motor so that excess current does not flow to the motor. Moreover, if the load is small, the motor is rotated by the set upper limit speed. Therefore, the performance is not lowered and the burning of the motor can be prevented.

[Structure of counter]

The counter 5 is provided to display the water depth of the bait installed at the tip end of the fishing line and to control the motor 4. The counter 5 has an upper case 5a and a lower case 5b as shown in Figs. 3 and 4. The upper case 5a is a ridge line portion 5c, 5d in which the display portion is formed in a fine front shape and has a slight depression from the display portion toward the left and right. The ridge portion 5c is connected to the side cover 14 in the same plane, and the ridge portion 5d is connected to the side cover 15 in the same plane. In the display portion of the upper casing 5a, a thinner stencil 88 having a slightly curved shape in which the trapezoidal sheets are slightly curved is fixed. In the cliché 88, a transparent cover 88a for the peep water depth display portion 98 is provided. On the bottom surface of the lower case 5b, a heat sink 5e made of an aluminum plate for cooling an electric field effect transistor (FET) 108b to be described later is provided.

As shown in FIG. 3, the counter 5 is provided with a water depth display unit 98 including a liquid crystal display for displaying the water depth data LX of the lure and the shed position from the water surface and the bottom. The operation button unit 99 is composed of, for example, three switch buttons disposed on the front side (lower side in FIG. 3) of the water depth display unit 98. In the inside of the counter 5, as shown in FIG. 4, the first circuit board 10 in which the water depth display unit 98 and the operation button unit 99 are disposed, and the second circuit disposed below the first circuit board 10 are provided. Substrate 11. The first circuit board 10 is smaller than the conventional one in order to achieve downsizing of the counter 5. In the mounting side of the operation lever 1 of the second circuit board 11, the wiring 101a of the adjustment operation lever 101 is led out from the connection portion of the upper and lower housings 5a and 5b toward the outside in the lateral direction. This prevents contact with the fishing line. The lead-out portion of this wiring is sealed by a weir, etc., and the inside of the counter 5 is watertightly held. Further, in the first and second circuit boards 10 and 11, the insulation is improved by applying a crucible to the soft electrode portion of the power supply line, the leg portion of the motor-driven electrolytic capacitor, and the soft electrode portion of the leg portion of the microcomputer. Prevents the effects of moisture from causing misuse.

As shown in FIG. 5, the water depth display unit 98 uses a segment type liquid crystal display 98a having a back light source 30. The back light source 30 is a light-emitting diode 30a having two colors that emit red and green, and a light guide plate 30b on which one light-emitting diode 30a is disposed.

The operation button unit 99 has a menu button MB that is arranged side by side on the lower side of the water depth display unit 98, a decision button DB, and a shed memo button TB. The menu button MB is a button used to select a display item in the water depth display unit 98. For example, in conjunction with the operation of the menu button MB, switching to the upper mode (the mode in which the water depth of the lure is displayed from the depth of the water surface) and the bottom mode (the mode in which the water depth of the lure is displayed from the water depth of the bottom) is switched. When the menu button MB is pressed for 3 seconds or longer, the control mode of the motor can be switched to the speed mode and the tension mode each time the button is pressed. Here, the speed mode is a mode in which the upper limit speed of the rotational speed of the reel 3 can be controlled in a multi-stage speed of 31 stages in accordance with the swing angle of the adjustment operating lever 101. The tension mode is a mode in which the upper limit tension of the tension acting on the fishing line can be controlled in a 31-stage multi-stage tension. Further, the 31 stages of the highest stage of the two modes are the speed-up speeds at which the motor 4 is operated by 100% load operation, and although the current is limited, the speed control is not performed.

The decision button DB is a button for determining the selection result. When the decision button DB is pressed for 3 seconds or longer, for example, the water depth data LX at that time is set to 0 as the reference position setting of the water depth 0. The shed memo button TB is a button for setting the water depth of the bait during operation as a shed position setting. Then, the water depth data LX is displayed by the line length from the set reference position. In addition, the angler usually presses the decision button to set 0 for the time when the fish is lurking on the surface of the sea.

Further, inside the counter 5, as shown in Fig. 6, a control unit (an example of a mode control device) 90 for controlling the water depth display unit 98 and the motor 4 is provided. In the control unit 90, a reel control unit 100 composed of a microcomputer is provided. In the functional configuration, the reel control unit 100 includes a first control unit 100a that controls the speed of the motor 4, and a second control unit 100b that corrects the tension of the motor 4 by the tension of the coil and controls the tension. . Moreover, the coil diameter can be obtained from the water depth data.

The reel control unit 100 is connected to an operation button unit 99 and an adjustment operation lever 101 that is swingably mounted to the side cover 15 for adjusting the speed of the reel and the tension of the fishing line, and the reel The number of rotations of 3 and the direction of rotation are, for example, a roll sensor (an example of a rotation speed detecting portion) 102 detected by two Hall elements arranged in parallel in the direction of rotation, and a temperature at which the temperature of the motor is detected. The sensor 103, the potentiometer 104 connected to the adjustment operation lever 101, and the water depth information of the fishing information display device 120 and the bait provided outside the reel are wireless (for example, IEEE 802.15.4 (ZigBee (Japanese registered trademark) The wireless communication unit 105 for communication with each other, and the buzzer control unit 100 is connected to various buzzer 106 for notification, water depth display unit 98, and various types of data. For example, the memory unit 107 composed of an EEPROM and the motor drive circuit 108 for driving the motor 4 by a pulse width modulation (PWM) (PWM) load operation ratio, and other input/output portions are provided in the motor drive circuit 108. Provided: a current that detects a current flowing to the motor 4 The output unit (an example of the load detecting unit and the tension detecting unit) 108a and the electric field effect transistor 108b. The temperature sensor 103 is mounted on the motor driving circuit 108 instead of directly detecting the temperature of the motor 4 The temperature of the electric field effect transistor (FET) 108b is detected. The electric field effect transistor 108b is mounted on the second circuit board 11.

The phishing information display device 120 displays and numerically displays the fish finder data (bottom position and shed position) similar to the fish finder 140 by communicating the data to each other by the fish finder 140 mounted on the fishing boat. Moreover, the wireless and the reel communicate with each other to draw the position and numerical value of the lure by the water depth data obtained from the reel.

[Control of the reel control unit]

The reel control unit 100 controls the speed and torque (tension) of the motor 4 in accordance with the amount of operation of the adjustment operating lever 101. Then, the water depth of the artificial bait attached to the tip end of the fishing line is calculated by the output of the reel sensor 102, and is displayed on the water depth display unit 98. Further, when the bottom position (water depth of the sea floor) or the shed position (water depth of the fish group) is set by the operation of the operation button portion 99, the calculated water depth and the set bottom position and the shed position coincide with each other and the bait arrives at the shed position or the bottom position. At this time, the buzzer 106 reports the matter.

Next, the control operation of the specific reel control unit 100 will be described with reference to the flowcharts of FIGS. 7 to 16 centering on the control of the motor 4.

[main example stroke type]

When the power is supplied to the reel control unit 100, the initial setting is performed in step S1 of Fig. 7. In this initial setting, various flags are set to be OFF, and the motor control mode is set to the speed mode, and the water depth display is set to the slave mode. In step S2, various display processes are performed. In this display processing, display processing of the material displayed on the water depth display unit 98 is performed. For example, display processing such as water depth data is performed.

In step S3, it is judged whether or not the input of the operation button portion 99 and the adjustment operation lever or the like is operated. In step S4, it is judged whether or not the reel 3 is rotated by the output from the reel sensor 102. In step S5, the temperature protection process of the motor 4 shown in Fig. 8 is carried out from the output of the temperature sensor 103. In step S6, it is determined whether or not the other processing such as the learning process based on the calculation of the line diameter and the learning of the relationship between the number of reel rotations of the line and the line length is performed.

If there is a key input, the process proceeds from step S3 to step S7. In step S7, the key input processing shown in Fig. 9 is executed. When it is determined in step S4 that the reel 3 is rotated, the flow proceeds from step S4 to step S8. In step S8, each operation mode process shown in Fig. 16 is executed. When the other processed command is executed, the process proceeds from step S6 to step S9 to execute another process to be commanded.

[temperature protection processing]

The temperature protection process of step S5 is a process of turning off the motor 4 when the temperature of the motor drive circuit 108 (that is, the temperature of the motor 4) is 90 degrees or more. In the temperature protection process, the temperature of the motor drive circuit 108 is read in by the output of the temperature sensor 103 in step S11 of Fig. 8. Since the temperature of the motor drive circuit 108 is slightly proportional to the temperature of the motor 4, the temperature of the motor 4 can be detected by the temperature of the motor drive circuit 108. In step S12, it is judged whether or not the temperature of the motor drive circuit 108 exceeds the first predetermined temperature (e.g., preferably 85 to 95 degrees Celsius, in this embodiment, 90 degrees Celsius). When the temperature of the motor drive circuit 108 exceeds 90 degrees, the flow proceeds from step S12 to step S13. In step S13, it is judged whether or not the ON (temperature) temperature flag FS is already ON when the temperature starts to exceed 90 degrees. When the temperature flag FS is not ON, the process proceeds to step S14 to turn on the temperature flag FS (ON), and the process proceeds to step S15. Step S14 is skipped when the temperature flag FS is already ON. In step S15, the motor 4 is turned off (OFF), and returns to the main routine. Thereby, the burning of the motor 4 at the time of an overload can be prevented.

When the temperature is equal to or lower than the first predetermined temperature, the process proceeds from step S12 to step S16. In step S16, it is judged whether or not the temperature flag FS is already ON. When the temperature flag FS is not ON, it returns to the main routine. When the temperature flag FS is already ON, the process proceeds to step S17 to determine whether or not the detected temperature Td falls to a second predetermined temperature lower than the first predetermined temperature (for example, 75 degrees Celsius to 85 degrees Celsius is preferable). In this embodiment, it is 80 degrees Celsius or less. By this judgment, the temperature protection process is terminated. When the detected temperature Td exceeds 80 degrees, the process returns to the main example stroke type, and if it is 80 degrees or less, the process proceeds to step S18. In step S18, it is judged whether or not the timer T1 is turned "ON". The timer T1 is for checking whether the state below the second predetermined temperature continues for a predetermined time t1 (for example, 20 seconds to 40 seconds, preferably 30 seconds in this embodiment). When the timer T1 is not ON (start), the process proceeds to step S19 to turn on the timer T1. When the timer T1 has been turned ON (ON), step S19 is skipped. In step S20, it is judged whether or not the timer T1 has ended and turned OFF. When the time is not over, the process returns to the main routine. When the time is over, that is, when the state of 80 degrees or less continues for 30 seconds or longer, it is considered that the overload state has been extinguished and the process proceeds to step S21 to turn off the temperature flag FS. (OFF), the temperature protection process is finished. After the temperature protection process is finished, the motor 4 can be actuated by returning the adjustment operating lever 101 to the operation start position (stage ST = 0).

[Key input processing]

In the key input processing of step S7, it is determined in step S31 of Fig. 9 whether or not the menu button MB has been pressed for 3 seconds or longer. In step S32, it is judged whether or not the adjustment operation lever 101 is operated from the operation start position. In step S33, it is judged whether or not the shed memo button TB and other buttons such as the single button selection of the decision button DB and the menu button MB are operated.

The menu button MB is. When it is pressed long, the flow proceeds from step S31 to step S34. In step S34, it is determined whether or not it is the speed mode. In the speed mode, the process proceeds to step S36 to set to the tension mode, and in the tension mode, the process proceeds to step S35 to set to the speed mode.

When it is judged that the adjustment operation lever 101 is operated to a position other than the operation start position (ST=0), the flow proceeds from step S32 to step S37. In step S37, it is judged whether or not the temperature flag FS is ON. When the temperature flag FS is ON, the process proceeds to step S33 in order to prohibit the motor control operation by the adjustment operation lever 101. When the temperature flag FS is not in the ON state, the process proceeds from step S37 to step S38. It is judged at step S38 whether or not it is the speed mode. In the speed mode, the process proceeds to step S39 to execute the speed mode processing. In the tension mode, the process proceeds to step S40 to perform the tension mode processing. When the other button is operated, the process proceeds from step S33 to step S41, and the process corresponding to the operated button is performed.

[Speed mode processing]

In the speed mode processing of step S39, the motor 4 is controlled to set the number of rotations of the reel 3 to the upper limit speed set at each stage. Further, the upper limit speed is corrected by the winding diameter of the spool 3, and actually, the motor 4 is controlled so that the winding speed of the fishing line wound around the spool 3 is constant.

In step S50 of Fig. 10, it is judged whether or not the intermittent flag FP3 used for the intermittent processing to be described later is turned "ON". When the discontinuous flag FP3 is off (OFF), the process proceeds to step S51. When the discontinuous flag FP3 is ON, the process proceeds to step S54.

In step S51, the number of stages ST set by the adjustment operation lever 101 and the rotation speed Vd of the reel 3 calculated by the output of the reel sensor 102 are read. In step S52, it is judged whether or not the speed Vd of the reel 3 is not full or the lower limit value Vst1 corresponding to the upper limit speed Vs of the protection phase STS to be described later. In step S53, it is judged whether or not the speed Vd of the reel 3 exceeds the stage ST or the upper limit value Vst2 of the upper limit speed Vs corresponding to the protection phase STS. Further, when the speed control is performed, the reason why the lower limit value Vst1 and the upper limit value Vst2 of the upper limit speed Vs are set in each stage ST is to prevent the load duty ratio from changing when the speed between the two speeds Vst1 and Vst2 fluctuates. There is no screaming sound that is more than a load change, which makes the feedback control stable. The upper limit value Vst2 and the lower limit value Vst1 are set within, for example, ±10% of the upper limit speed Vs.

In the case of a high load, the first protection process for interrupting the operation of the motor 4 is performed. In the case of a high load, the second protection process for decelerating the motor 4 is performed in the case of a high load, and the process returns to the key input process.

When the speed Vd is not equal to the lower limit value Vst1, the process proceeds from step S52 to step S56. In step S56, it is determined whether or not the second protection flag FP2 that is turned "ON" is turned "ON" during the second protection process to be described later. When the second protection flag FP2 is turned "ON", the process proceeds from step S56 to step S61 in order to prohibit the speed increase operation from the protection phase STS decelerated by the second protection process to the operation of the operation lever in the stage ST on the high speed side. . In step S61, the set phase ST is determined by the second protection process to determine whether or not the set protection phase STS is exceeded. When the set phase is beyond the protection phase STS, the process proceeds to step S53 in order to rush the operation lever operation prohibiting the speed increase operation. When the set phase ST is set to be equal to or lower than the protection phase STS by the operation of the operation lever, the process proceeds from step S61 to step S62, and the second protection flag FP2 is turned OFF (OFF) to step S57.

When the second protection flag FP2 is OFF, the process proceeds from step S56 to step S57 to read the current first load operation ratio D1. The first duty operation ratio D1 is stored in the memory unit 107 every time the setting is changed. Further, the maximum value DUst and the minimum value DLst are set in each stage ST, and when the stages ST are set first, for example, the first load operation ratio D1 = ((DUst + DLst) / 2) is set. In step S58, it is determined whether or not the current first load operation ratio D1 exceeds the maximum value DUst of the set stage. If it is exceeded, the process proceeds to step S60 to set the maximum value DUst at the first load operation ratio D1. If it is not exceeded, the process proceeds from step S58 to step S59, and only the first load operation ratio D1 is increased by a predetermined increase point DI (for example, 1%) to step S53. Further, the load operation ratio at the highest stage (ST=31) is set to 100%, but the maximum value DUst is set to 85% or less in the previous stage (ST=1 is 30).

When the speed Vd exceeds the upper limit value Vst2, the process proceeds from step S53 to step S63 to read the current first load operation ratio D1. This first load operation ratio D1 is also the same as step S57. In step S64, it is determined whether or not the current first load operation ratio D1 is lower than the minimum value DLst of the set stage. If it is lower than the case, the process proceeds to step S66, and the minimum value DLst is set at the first load operation ratio D1. If it is not lower than the case, the process proceeds from step S64 to step S65, and only the first load operation ratio D1 is decreased by a predetermined reduction point DI (for example, 1%) to step S54.

[First Protection Process] The first protection process in step S54 is a motor protection process that is effective when the stage ST is 5 to 31 in the speed mode, and is turned off (ON/OFF) when the motor 4 is under a high load. The current flow prevents burnout of the motor 4. In the first protection process, the current value flowing to the motor 4 (that is, the load acting on the motor 4) is the first current value that is 50% or more and 90% or less of the maximum current value (for example, 18A) flowing to the motor ( For example, 12A) continuous first predetermined time (for example, preferably 0.5 second to 2 seconds, in this embodiment 1 second), and the rotational speed below 40% of the upper limit speed of the highest speed stage is also the first speed (for example) When the first state in which the reel 3 is rotated is the first state in which the reel 3 is rotated, the intermittent current of the ON/OFF is caused to flow to the motor 4 for intermittent control. In addition, when the speed is the second speed (for example, the upper limit speed of the 13th stage (ST=13)) on the high speed side of the first speed, it is determined that the load is reduced, the intermittent control is released, and the normal speed control or the tension control is returned.

Specifically, the rotational speed Vd and the load current value Id are read in step S69 of Fig. 11 . In step S70, it is determined whether or not the current stage ST is 5 or more. When the phase ST is 5 or more, the process proceeds to step S71, and the current value Id flowing to the motor 4 detected by the current detecting unit 108a is determined, that is, whether the load is the first current value, that is, 12A or more. When the current value Id is 12A or more, the process proceeds to step S73, and if the first condition is satisfied, it is determined whether or not the first protection flag FP1 that is turned "ON" is turned "ON". When the first protection flag FP1 is not turned "ON", the process proceeds to step S74. When the first protection flag FP1 is already turned "ON", the process proceeds to step S78 by skipping steps S73 to S77.

In step S74, it is judged whether or not the timer T2 for measuring the first predetermined time t2 has been turned ON. When the timer T2 is not ON, the process proceeds to step S75 to turn the timer T2 ON (ON) to step S76. When the timer T2 is ON, the process proceeds to step S76 by skipping step S75.

In step S76, it is judged whether or not the timer T2 is turned off (OFF). That is, it is judged whether the load and the speed have passed for one minute from satisfying the predetermined condition. When it is determined that the timer T2 has expired, the process proceeds to step S77 to make it possible to recognize that the first protection flag FP1 for satisfying the first condition is ON. In step S78, an on/off current is flown to the intermittent control process in which the motor 4 performs driving. In step S79, it is determined whether or not the load is a second current value larger than the first current value, that is, 15 A (amperes) or less. When the load is 15 A or less, the process proceeds to step S80. In step S80, it is determined whether or not the speed Vd is equal to or higher than the upper limit speed Vs13 of the 13th step (ST13). When the speed Vd is equal to or greater than the upper limit speed Vs13, it is determined that the first protection mark FP1 is turned off (OFF) without requiring protection. When the first protection mark FP1 is OFF, the motor 4 is controlled by a normal speed or tension.

When the determination in steps S70, 71, 72, 76, 79, and 80 is NO, the process returns to the speed mode process.

[intermittent processing]

In the interrupt processing of step S78, it is determined in step S91 of Fig. 12 whether or not the timer T3 for measuring the second predetermined time (for example, 15 seconds) from the intermittent processing ends. In step S92, it is determined whether or not the timer T3 is turned "ON". When the timer T3 is not turned "ON", the process proceeds to step S99, and the timer T3 is turned ON (ON) to start timing and then moves to step S93. When the timer T3 is already ON, the process proceeds to step S93 by skipping step S99. In step S93, the temperature of the motor drive circuit 108, that is, the temperature Td of the motor 4 is read in by the output of the temperature sensor 103. In step S94, it is judged whether or not the temperature Td of the motor 4 exceeds the first predetermined temperature (for example, 50 degrees Celsius to 70 degrees Celsius is preferable, and in this embodiment, 60 degrees). In this intermittent control, the ON (ON) time and the OFF (OFF) time of the motor 4 are changed by the first predetermined temperature. That is, when the temperature is low, the ON time is longer than the OFF time, and when the temperature is high, the OFF period is set to be longer than the ON time. When the temperature Td is less than 60 degrees Celsius, the process proceeds from step S94 to step S95. In step S95, the motor 4 is turned "ON" for a time tn1 (for example, 600 to 1000 msec, which is 750 msec in this embodiment). In step S96, the motor 4 is turned OFF (OFF) time tf1 (for example, 350 to 750 msec shorter than time tn1, 500 msec in this embodiment) to return to the first protection process. When the temperature Td is 60 degrees or more, the process proceeds to step S97, and the motor 4 is turned ON for a time tn2 (for example, 6001 to 000 msec, which is 750 msec in this embodiment). In step S98, the motor 4 is turned OFF for a time tf2 (for example, 800 to 1200 msec longer than the time tn2, in this embodiment, 1000 msec), and returns to the first protection process.

When the timer T3 is the end of the time, that is, if the intermittent processing is 15 seconds or longer, the flow proceeds from step S91 to step S100, and it is determined whether or not the intermittent flag FP3 is ON. The discontinuous mark FP3 is a mark that is turned ON when the intermittent process is the second predetermined time elapsed. When the discontinuous flag FP3 is not turned "ON", the process proceeds to step S101 to turn the discontinuity flag FP3 ON. In step S102, the motor 4 is turned off (OFF). When the discontinuous flag FP3 is already ON, steps S101 and S102 are skipped. In step S103, it is judged whether or not the timer T4 has been turned ON. The timer T4 is a timer for measuring the return of the rotation of the motor 4 after the time when the motor 4 is turned off (OFF), and is turned off (OFF) when the time elapses after 30 seconds elapses. When the timer T4 is not turned "ON", the process proceeds to step S104 to turn on the timer T4. When the timer T4 is already ON, step S104 is skipped. In step S105, it is judged whether or not the timer T4 ends the OFF (OFF). When the time has elapsed, the process proceeds to step S106, and the intermittent flag FP3 is turned OFF to return to the first protection process in order to make the motor 4 operable. Thereafter, when the adjustment operation lever 101 is returned to the operation start position, the motor 4 becomes operable.

In such a first protection process, the motor 4 is prevented from generating heat by intermittently rotating the motor 4 so that excess current does not flow to the motor 4 in a high load state. Further, if the load is small, the motor 4 is rotated by the set upper limit speed. Therefore, the performance is not lowered to prevent the burning of the motor 4.

[Second protection process]

The second protection process of step S55 is effective only when the speed mode is eight or more stages, and that the motor 4 is decelerated when the load acting on the motor 4 is high. In the second protection process, the load detected by the current detecting unit 108a is the first one that satisfies the fourth predetermined time t5 (for example, three seconds) in the state of the third current value Is (for example, 15 A) or more. In the case of the condition, the target speed of the upper limit speed which is at least one stage lower than the detected rotation speed (two stages in this embodiment) is set. And comparing: the first load that has elapsed after the fifth predetermined time (for example, three seconds) after the target speed is set, and the second load that has elapsed since the sixth predetermined time (for example, one second), and the second load is predetermined to be the first load. When the amount (for example, 1A) is large, the target speed is set to the upper limit speed of the lower stage by the interval of 1 second, and the second load is smaller than the first load predetermined amount (for example, 0.5 A), and the target speed is 1 second. The interval return is set to an upper limit speed of at least one higher stage.

In the second protection process, in step S111 of Fig. 13, the rotation speed Vd, the load current value Id, the current stage ST, and the protection stage STS in which the second protection process is set are read. In step S112, it is determined whether or not the current stage ST is 8 or more. When the stage ST is 8 or more, the process proceeds to step S113. When the stage ST is 8 or not full, processing is not performed and the process returns to the speed mode processing. In step S113, it is determined whether or not the current value Id of the display load is equal to or greater than the third current value Is. When the current value Id is equal to or greater than the third current value (for example, 15 A) Is, the process proceeds to step S114, and it is determined whether or not the timer T5 has expired. The timer T5 is for measuring the predetermined time t5 for determining the first condition required for the second protection process. The timer T5 shifts to step S115 when the time is not over, and determines whether or not the timer T5 has started (ON). When the timer T5 is not turned "ON", the process proceeds to step S116 to turn on the timer T5 (ON) and start timing. When the timer T5 is ON, the process proceeds to step S117, skipping step S116.

When the timer T5 is the end of the time, that is, when the first condition that the load is 15A or more and the state continues for 3 seconds or longer, the process proceeds from step S114 to step S117. In step S117, it is determined whether or not the protection phase STS is 8 or more. In this second protection process, the deceleration is not performed in seven stages or less. Therefore, in the second protection process, if the protection phase STS is less than eight stages, the process returns to the speed mode process. When the protection phase STS is equal to or greater than eight stages, the process proceeds to step S118. In step S118, it is determined whether or not the second protection flag FP2 that is turned "ON" when the first condition is satisfied and the first deceleration processing is turned ON. When the second protection flag FP2 is not turned "ON", the process proceeds to step S119 to turn on the second protection flag FP2. In step S120, it is determined whether the protection phase STS is 8 segments. In this embodiment, since the seventh stage is not decelerated, if the protection phase STS is 9 or more, the process proceeds to step S121, and the protection phase STS is set to be lower from the stage STvd corresponding to the upper limit speed of the current rotational speed Vd. Two-stage phase (STvd-2). Specifically, it is set to be lower than the current speed Vd, that is, from the stage of the highest upper limit speed. When the protection phase STS is eight-stage, the process proceeds to step S122, and the phase STvd corresponding to the upper limit speed of the current rotational speed Vd is one phase lower (STvd-1), that is, the protection phase STS is set to seven stages. In the execution of the second protection process (the second protection flag is ON), if the operation lever 101 is operated in such a manner as to be in the protection stage STS or more, the operation is performed in step S61 of the speed mode process in Fig. 10 When the stage ST is beyond the protection stage STS, its operation is eagerly observed, and high-speed operation above the protection stage STS cannot be performed.

In step S123, it is judged whether or not the timer T6 has ended. This timing T6 is a timing device that is assembled from the initial deceleration and waits for a predetermined time (for example, three seconds) to be assembled. When the timer T6 is time-lapse, the process proceeds to step S126, and the current first load, that is, the current value Idn, is read in, and the process returns to the speed mode process. Also, the variable n is initially set to 1. When the timer T6 has not expired, the process proceeds to step S124, and it is determined whether or not the timer T6 has been turned ON. When the timer T6 is not turned "ON", the process proceeds to step S125 to turn on the timer T6 (ON) and start timing. When the timer T6 is already ON, the process proceeds to step S126 by skipping step S125. Here, the reason why the current value is not read immediately from the second-stage deceleration but waits for 3 seconds is that the current value is unstable when the current value is read immediately after the second-stage deceleration.

When it is determined that the current current value (current load) Id read is not equal to the third current value Is, the flow proceeds from step S113 to step S136. In step S136, the second protection flag FP2 is turned OFF (OFF) and the second protection process is returned to the speed mode process. Thus, the protection phase STS is also reset to 31 segments.

When it is determined that the second guard flag FP2 is ON, the process proceeds from step S118 to step S127, and it is determined whether or not the timer T7 has expired. This timing T7 is a timing device that is assembled to wait for a predetermined time (for example, one second) after detecting the first load, that is, the current value Idn. When the timer T7 is time-lapse, the process proceeds to step S130, and the variable n is incremented by one. When the timer T7 is not over, the process proceeds to step S128, and it is determined whether or not the timer T7 has been turned ON. When the timer T7 is in the ON state, the process proceeds to step S129 to turn on the timer T7 (ON) and start timing. When the timer T7 is already ON, the process proceeds to step S130, skipping step S129. In step S131, the current second load, that is, the current value Idn, is read.

In step S132, it is judged whether or not the read second load is the current value Idn which is 70% or less of the third current value Is. When the current value Idn is 70% or less of the third current value, the process proceeds to step S136, and the second protection flag FP2 is turned off (OFF) to cancel the second protection process. When the current value Idn exceeds 70% of the third current value Is, the process proceeds to step S133. In step S133, it is determined whether or not the second load (Idn) currently read is 1A or more larger than the first load (Id(n-1)) read in the previous deceleration. When the load is increased by 1A or more, the process proceeds to step S134, and the determination of the second load at the next time point after one second decreases the value of the current current value Idn of the first load as a comparison control by 0.1A. . In step S135, the stage ST is set to return to the speed mode processing from the stage (STvd-1) which is one stage lower than the stage STvd corresponding to the upper limit speed of the current rotational speed Vd.

When the second load (Idn) is not larger than the first load (Id(n-1)) read in the previous deceleration by 1A or more, the process proceeds from step S133 to step S137. In step S137, it is judged whether or not the second load, that is, the current value Idn, reaches the maximum current value (for example, 18A) flowing to the motor 4. When the maximum current value is reached, the process proceeds to step S134 to perform the deceleration process, and if it does not arrive, the process proceeds to step S138.

In step S138, it is determined whether or not the first load (Id(n-1)) is greater than the second load (Idn) by 0.5A or more. When the first load is 0.5 A or more larger than the second load and the load is decreased, the process proceeds to step S139, and the stage ST is set to a stage one step higher than the stage STvd corresponding to the upper limit speed of the current rotational speed Vd (STvd). +1), return to speed mode processing. When the increase in the second load is less than 1 A or the second load is less than 0.5 A, no processing is returned to the speed mode processing.

In the second protection process, when the speed of the deceleration motor 4 is at least one stage lower than the current rotational speed, the current flowing to the motor 4 is reduced. Excess current does not flow to the motor 4. Further, if the load is further reduced, the rotational speed of the motor is increased, and if the load is increased, the rotational speed of the motor is further reduced. Therefore, the excess current does not easily flow to the motor, and when the current is continuously supplied to the motor at the upper limit speed, the load on the motor can be suppressed, and the motor can be prevented from being burnt.

Further, in step S61 of the speed mode processing in Fig. 10, even if the target speed is set to be higher than the upper limit speed on the lower side of the speed, the target speed is canceled, so that the excess current is less likely to flow. When the upper limit speed is changed to the higher speed side than the target speed, the change is sneaked. Therefore, in the second protection process, the protection phase STS is not shifted to the high speed side.

[Tension mode processing]

In the tension mode processing of step S30, the number of stages ST set by the adjustment operation lever 101 and the tension Qd corrected by the line diameter of the detection result of the current detection unit 108a are adjusted in step S141 of Fig. 14 . Read. In step S142, it is determined whether or not the tension Qd is less than the lower limit value Qst1 of the upper limit tension Qs of the corresponding stage ST. In step S143, it is determined whether or not the tension Qd exceeds the lower limit value Qst2 of the upper limit tension Qs of the corresponding stage ST. Further, when the tension control is performed, the lower limit value Qst1 and the upper limit value Qst2 of the upper limit tension Ts are provided in each stage ST, and the load duty ratio does not change when the tension between the tensions Qst1 and Qst2 fluctuates as in the speed mode. The load-to-work ratio is not generated when the screaming sound changes frequently, and the feedback control is stable. The upper limit value Qst2 and the lower limit value Qst1 are set within, for example, ±10% of the upper limit tension Qst.

In step S144, it is determined whether or not the stage ST is the 31st segment of the highest stage, and in the case of the 31st stage, the process proceeds to step S146, and the first protection process shown in Fig. 11 is executed. When the stage ST is other than the 31st stage, the process proceeds to step S145, and the process proceeds to the third protection process shown in Fig. 15. When the processing of these is completed, the processing returns to the key input processing.

When the tension Qd is not equal to the lower limit value Qst1, the process proceeds from step S142 to step S147. In step S147, the current second load operation ratio D4 is read. This second duty operation ratio D4 is memorized in the memory unit 107 every time the setting is changed. In step S148, only the second load duty ratio D4 is increased by a predetermined increase score DI (for example, 1%) to step S143. This is continued until the tension Qd exceeds the lower limit value Qst1.

When the tension Qd exceeds the upper limit value Qst2, the process proceeds from step S143 to step S149 to read the current second load operation ratio D4. This second duty operation ratio D4 is also the same as step S147. In step S150, only the second load duty ratio D4 is decreased by a predetermined minus point DI (for example, 1%) to step S144. This is continued until the tension Qd is lower than the upper limit value Qst2.

In this tension mode processing, the tension reduction processing by the second protection processing is not performed as compared with the speed mode processing. This is because, in the tension mode, the current value (tension) is determined at each stage ST.

[3rd protection process]

The third protection process in step S145 is a motor protection process that is effective when the stage ST is 5 to 30. Since it is slightly the same as the first protection process for the speed mode, it is changed to the tension mode. In the third protection process, the current value flowing to the motor 4 (that is, the load acting on the motor 4) is the first current value that flows to 50% or more and 90% or less of the maximum current value (for example, 18A) of the motor (for example, 11A) is a third state in which the predetermined time (for example, 30 seconds to 60 seconds, and 45 seconds in this embodiment) is achieved, and an intermittent current of ON/OFF is performed to flow to the motor 4. The second intermittent control.

Specifically, it is determined in step S160 of Fig. 15 whether or not the current stage ST is 5 or more. When the phase ST is 5 or more, the process proceeds to step S161, and the current value Id flowing to the motor 4 detected by the current detecting unit 108a is determined, that is, whether the load is the first neon value, that is, 11A or more. When the current value Id is 11A or more, the process proceeds to step S162, and if the third condition is satisfied, it is determined whether or not the third protection flag FP4 that is turned "ON" is already ON. When the third protection flag FP4 is not turned "ON", the process proceeds to step S163. When the third protection flag FP4 is already turned "ON", the process proceeds to step S167 by skipping steps S163 to S166.

In step S163, it is judged whether or not the timer T8 for measuring the elapsed time t8 after the current value Id exceeds 11A has been turned ON. When the timer T8 is not ON, the process proceeds to step S164 to turn on the timer T8. When the timer T8 is already ON, the process proceeds to step S165 by skipping step S164. In step S165, it is judged whether or not the timer T8 is turned off (OFF). That is, it is judged whether or not 45 minutes have elapsed after the load satisfies the predetermined condition. When it is determined that the timer T8 has expired, the process proceeds to step S166 to turn on the third protection flag FP4 for satisfying the third condition. In step S167, the intermittent control process of driving the on/off (ON/OFF) current to the motor 4 is performed. This intermittent processing is the processing shown in Fig. 12 which is the same as in the speed mode. In step S168, it is determined whether or not the load is a fourth current value smaller than the third current value, that is, 10 A or less. When the load is 10A or less, the process proceeds to step S169. In step S169, it is determined that protection is not required and the third protection flag FP4 is turned off (OFF). When the third protection mark FP4 is OFF, the motor 4 can be operated by returning the adjustment operation lever 101 to the operation start position.

When the determination in steps S160, 161, 165, and 168 is NO, the process returns to the tension mode process.

[Each action mode processing]

In each operation mode processing of step S8, it is determined in step S171 of Fig. 16 whether or not the rotation direction of the reel 3 is the line discharge direction. This determination is to determine whether or not any of the Hall elements of the reel sensor 102 is pulsed first. When it is determined that the rotation direction of the reel 3 is the line discharge direction, the flow proceeds from step S171 to step S172. In step S172, the water depth is calculated from the data stored in the memory unit 107 from the number of reels of the reel each time the number of reels is reduced. This water depth is displayed by the display processing of step S2. In step S173, it is judged whether or not the obtained water depth coincides with the bottom position, that is, whether the artificial bait reaches the bottom. The bottom position is set in the memory unit 107 by pressing the memo button MB when the bait is reached. In step S174, it is determined whether or not it is another mode such as a learning mode. When it is not in other mode cases, the processing of each action mode is ended and the process returns to the main routine.

If the water depth coincides with the bottom position, the flow proceeds from step S173 to step S175, and the buzzer 106 is called to notify the bait to reach the bottom. In the case of the other mode, the process proceeds from step S174 to step S176, and the other mode designated is executed.

When it is judged that the rotation of the reel 3 is the wire winding direction, the flow proceeds from step S171 to step S177. In step S177, the water depth is calculated by reading the data stored in the memory unit 107 from the number of reels of the reel. This water depth is displayed by the display processing of step S2. In step S178, it is judged whether or not the water depth coincides with the rim stop position. When it is not taken up to the rim stop position, return to the main routine. When the ship edge stop position is reached, the process proceeds from step S178 to step S179. In step S179, the buzzer 106 is called in order to notify that the bait is located at the edge of the ship. In step S180, the motor 4 is turned off (OFF). As a result, the fish is placed in a position where it is easy to take in when the fish is caught. This rim stop position is set, for example, when the reel 3 is stopped for a predetermined time or longer within a water depth of 6 m.

With respect to the main example stroke pattern of Fig. 17, the high-load pulling processing of step S199 is inserted after the temperature protection processing of step S5. In this high-load traction process, when the high load (for example, the current value is 5 A or more), the traction mechanism 8 slides and is less than a predetermined winding length (for example, 20 m) between predetermined times (for example, 1 minute), and cannot be rolled up. When the line is on, the motor 4 is stopped.

In the high load pulling process, the load current value Id is read in step S181 of Fig. 18. In step S182, it is judged whether or not the timer T9 for measuring the predetermined amount of time for rolling up the determination (for example, one minute) ends. The timer T9 shifts to step S183 when the time is not over.

In step S183, it is determined whether or not the load current value Id is 5A or more. When the load current value Id is 5A or less, the process proceeds to step S184, and when the timer T9 starts, it is turned OFF. In step S185, when the high-load traction flag FP6 is turned "ON", it is turned OFF, and returns to the main routine. The high-load traction flag FP6 is turned on (ON) by the step S191 when the traction mechanism 8 is not wound up by a predetermined amount for the high-load traction process.

When the load current value Id is 5A or more, the process proceeds from step S183 to step S186. In step S186, it is determined whether or not the timer T9 is turned "ON". When the timer T9 is not turned "ON", the process proceeds to step S187. The count of pulses output from the reel sensor 102 is started. In step S188, the timer T9 is turned "ON" to return to the main routine.

When the timer T9 is the end of time, the process proceeds from step S182 to step S189. In step S189, the count of the reel pulses is ended. In step S190, it is judged from the count result and the coil diameter that the amount of winding up is a winding up to 20 m. When the amount of winding up is 20 m or less, the process proceeds to step S191 to turn on the high-load traction flag FP6. In step S192, the motor 4 is turned off (OFF). When the motor 4 is turned off (OFF), the motor 4 can be operated when the adjustment operation lever 101 is returned to the operation start position after the high-load traction state is released. Further, in the case where the high-load traction flag FP6 is ON, the operation of adjusting the operation lever 101 is canceled in the same manner as the temperature flag FS and the discontinuity flag FP3 in the step S37 of FIG. Thereby, it is also possible to prevent damage caused by heat generation of the motor 4 when the traction is actuated.
