Description

BACKGROUND OF THE INVENTION 1. Field of the Invention 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. [Prior Art] The electric reel which can be rotated by the motor when the reel is wound up is provided with a reel body and a reel rotatably supported by the reel body, and the reel is manually An operating lever for rotation and an electric motor that drives the reel in a winding direction. An operation panel is mounted on the upper surface of the reel body, and a display for displaying the water depth and various input switches are provided. In the electric reel, the upper limit winding speed of the conventional reel is controlled in a plurality of stages at a plurality of stages (for example, refer to Patent Document 1). In the conventional electric reel, the upper limit speed is set to a plurality of stages by a swinging lever provided on the operating lever side of the operating panel and provided on the side of the reel body. In the conventional electric reel, the upper limit speed of each stage is set in accordance with the swing angle of the operating lever, which is displayed on the display. In the motor control device, the number of detected reel rotations is controlled to control the motor so that the detected reel rotation speed becomes the speed at the set stage. [Patent Document 1] Japanese Laid-Open Patent Publication No. 2000-139299 (Summary of the Invention) - 5 - 201002199 (Problems to be Solved by the Invention) In the above-described conventional configuration, even if the load is high, the set upper limit speed is reached. When the rotation of the reel does not rise, an unnecessary current continues to flow toward the motor in order to rise up to the upper limit speed. When this excess current flows, the load on the motor increases and the motor may burn out. An object of the present invention is to prevent a motor from being burned when the motor is controlled at a plurality of speeds by suppressing a load on the motor. (Means for Solving the Problem) 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 and a load detection device. And an upper limit speed setting unit, a first target speed setting unit, a load comparing unit, a second target speed setting unit, and a 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 値. 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 target speed setting unit is the first predetermined time continuous in a state in which the load detected by the load detecting unit is equal to or greater than a predetermined first current 値 that is smaller than the maximum current flowing to the motor, and At least the upper limit speed at which the detected rotational speed is not full, that is, the first condition, is set to a target speed corresponding to the upper limit speed that is at least one stage lower than the rotational speed. The load comparison unit compares the first load after the target speed is set and the second load after the second predetermined time elapses. When the second load is larger than the first load predetermined amount -6 - 201002199, the second target speed setting unit sets the target speed to an upper limit speed of at least one lower stage, and the second load is smaller than the first load predetermined amount. It is to set the target speed to an upper limit speed of at least one higher stage. When the first condition is not satisfied, the motor control unit controls the motor to set the rotation speed of the reel to the set upper limit speed, and when the first and second target speed setting units set the target speed, the motor is controlled to reel. The rotation speed becomes the set target speed. In this motor control device, normally, the control motor is set to the upper limit speed set by the upper limit speed setting unit. When the load is increased, the load detected by the load detecting unit is higher than a predetermined first current 値 which is smaller than the maximum current 流动 flowing to the motor (for example, 50 to 90% of the maximum current )). When the load state is the first condition for the first predetermined time, the target speed corresponding to the upper limit speed that is at least one stage lower than the rotational speed is set. And comparing the first load detected at the time and the second load after the second predetermined time has elapsed, and when the second load is greater than the first load predetermined amount, the target speed is set to an upper limit speed of at least one lower stage. The second load is smaller than the first load predetermined amount, and the target speed is set to an upper limit speed of at least one higher stage. When the target speed is set, the motor control unit controls the motor speed so as not to become the upper limit speed but to become the target speed. Here, when the high-load state is satisfied by the first condition, the speed of the motor is decelerated to an upper limit speed which is at least one stage lower than the current rotational speed, and the current flowing to the motor is reduced, so that unnecessary current does not flow to the motor. 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 the current is held until the upper limit speed is reached. -7- 201002199 When the multi-stage speed control is continued to the motor, the load on the motor can be suppressed and the motor is not burned. In the motor control device for the electric reel according to the second aspect of the invention, the first target setting unit is configured to satisfy the first condition and the second condition that the rotational speed is continuously continuous for the first predetermined time and the upper limit speed is not satisfied. , set the target speed. In this case, the discrimination accuracy of the high load is further increased, and the excess current is less likely to flow. In the motor control device of the electric reel according to the invention of the first aspect of the invention, the motor control unit is a motor control unit that changes the upper limit speed to a lower speed than the target speed by the upper limit speed setting unit. The target speed is released and the motor is controlled to become the upper limit speed. In this case, even if the target speed is set, if the upper limit speed is set on the lower side than the speed, the target speed is canceled, so the excess current is less likely to flow. In the motor control device according to the fourth aspect of the invention, the motor control unit is configured such that the upper limit speed is changed to a higher speed side than the target speed by the upper limit speed setting unit, and the motor control unit ignores the Change, control the motor to make the target speed. In this case, in the deceleration control, since the speed increase on the high speed side where the load on the motor is increased is prohibited, the load on the motor is further reduced. In the motor control device for the electric reel according to the fifth aspect of the invention, the second target speed setting unit lowers the target speed by using a low speed phase of half or less of the maximum stage as a limit. In this case, since the speed is decelerated in the low speed range where the current is not large, there is no excessive deceleration in which the performance of the reel is low. -8-201002199 The motor control device for the electric reel according to the invention of claim 5, wherein the motor control unit is in a state in which the load state of the first current 値 or more is continuously longer than the first predetermined time by the third predetermined time. In the case, when the rotation speed of the reel is lower than the speed of the intermediate stage on the high speed side of the low speed stage, an intermittent current of ON/OFF is caused to flow toward the reel. In this case, since the motor does not decelerate when the target speed is lower than the intermediate speed, the motor is intermittently operated. Therefore, when the rotation of the motor is lowered by a high load, the excess current does not flow to the motor and the motor can be suppressed. heat. 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 motor can be prevented from being burnt. [Effects of the Invention] According to the present invention, when the high-load state is satisfied by the first condition, the current flowing to the motor is reduced by decelerating the speed of the motor to an upper limit speed that is at least one stage lower than the current rotational speed. Excess current does not flow to the motor. 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'. When the current is continuously supplied to the motor for the speed control until the upper limit speed is reached, the load on the motor can be suppressed and the motor can be prevented from being burnt.

For example, in conjunction with the operation of the menu button MB, the mode is switched 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). When the menu button Μ B is pressed for 3 seconds or longer, the motor control mode 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 lever 1 0 1 . 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 three-stage multi-stage tension.

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 ΤΒ is a button for setting the water depth of the bait during operation as a shed position. 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 the squat when the water is on the sea surface. 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 portion 98 and the motor 4 is provided. In the control unit 90, a reel control unit 1 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 that controls the tension by correcting the tension of the motor 4 by the coil diameter. 1 00b. Moreover, the coil diameter can be obtained from the water depth data.

In the cord reel control unit 1A, various buzzer for notification is connected. And a water depth display unit 98, and a memory unit 107 that is composed of, for example, an EEPROM that stores various data, and a motor drive circuit 1 that drives the motor 4 by a pulse width modulation (PWM) load operation ratio, And other input and output parts. In the first aspect, a current detecting unit (an example of a load detecting unit and a tension detecting unit) that detects a current flowing to the motor 4 is provided, and an electric field effect transistor 1 〇 8 b is provided. The detector 1 〇3 is not detected by the temperature of the motor 4 directly -14 - 201002199, but is detected by the temperature of the electric field effect transistor (FET) 10 8b mounted on the motor drive circuit 108. The electric field effect transistor 8b is mounted on the second circuit board 1 1. The fishery information display device 1120 is configured to communicate with each other by the fish finder 140 and the wireless device mounted on the fishing boat, and will be the same as the fish finder 1 40. The fish finder data (bottom position and shed position) are displayed and displayed in number. Moreover, the wireless and the reel are communicated with each other, and the position of the bait is displayed and displayed by the water depth data obtained from the reel. [Reel Control Unit Control] The reel control unit 1 控制 controls the speed and torque (tension) of the motor 4 in accordance with the amount of operation of the adjustment lever 1 〇 1. Further, it is calculated by the output of the reel sensor 102 to be mounted on the fishing line. The apex of the line Further, it 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 When the shed position is the same and the bait arrives at the shed position or the bottom position, the buzzer 016 is notified of the matter. Next, the control operation of the specific reel control unit 100 is referred to the control of the motor 4 as a center. The flowchart of Fig. 16 is explained. [Main example stroke type] When the power supply reel control unit 1 is turned on, the initial setting is performed in step S1 of Fig. 7. In this initial setting, various flags are set to OFF (OFF), and the motor's control mode is set to speed mode' -15- 201002199 The water depth display is set to the slave mode. In step S2, various display processing is 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 〇2. In step S5, the temperature protection process of the motor 4 shown in Fig. 8 is performed 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 coil diameter and the learning of the relationship between the number of reels of the fishline and the line length is performed. If there is a key input, the operation proceeds from step S3 to step S7. In step S7, the key input processing shown in Fig. 9 is carried out. If 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 of the operation mode processes 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 of the command. [Temperature Protection Process] The temperature protection process in step S5 is a process of turning off the motor 4 when the temperature of the motor drive circuit 1 ( 8 (i.e., the temperature of the motor 4) is 90 degrees or more. In the temperature protection process, the temperature of the motor drive circuit 〇 8 is read in by the output of the temperature sensor 1 〇 3 in step S 1 1 of Fig. 8. Since the temperature of the motor drive circuit 1 〇 8 is slightly proportional to the temperature of the motor 4, the temperature of the motor 4 of -16 - 201002199 can be detected by the temperature of the motor drive circuit 1 〇 8. In the step s 1 2, 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 1 〇 8 exceeds 90 degrees, the process proceeds from step S12 to step S13. In step S13, when the temperature starts to exceed 90 degrees, it is judged whether or not the temperature flag FS of ON is already ON. When the temperature flag FS is not ON (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 (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 overload can be prevented. When the temperature is equal to or lower than the first predetermined temperature, the process proceeds from step S1 2 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 ('ON'), it returns to the main routine. When the temperature flag FS is already ON (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). In this embodiment, it is 80 degrees Celsius or less. By this, 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 s 1 8 . In step S188, it is judged whether or not the timer τ1 is turned ON. The timer T1 is for checking whether the state below the second predetermined temperature continues for a predetermined time 11 (e.g., preferably 20 seconds to 40 seconds, in this embodiment, 30 seconds). When the timer T1 is not ON (start), the transition timer -17-201002199 to step S19 turns the timer T1 ON. Step S19 is skipped when the timing τΐ has been turned on (Ο Ν ). In step S20, it is judged whether or not the timer Τ1 is over and turned off (OFF). When the time is not over, return to the main routine. When the time is over, that is, if the state below 8 degrees lasts for more than 30 seconds, the overload state is considered to have been extinguished and the flow is shifted to step S 2 1 to make the temperature. The flag FS is off (〇FF), and the temperature protection process is terminated. After the temperature protection process is finished, the adjustment operation lever 101 is returned to the operation start position by the day (phase ST = 〇), and the motor 4 can be operated. [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. It is judged in step S32 whether or not the adjustment operation lever 1 〇 1 is operated from the operation start position. In step S33, it is judged whether or not the other functions such as the shed memo button TB and the decision button DB and the single button of 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 judged 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 to step S3 5 to the speed mode. When it is judged that the adjustment operation lever 110 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 (on). When the temperature flag F S is ON (〇 N ), the process proceeds to step S 3 3 in order to prohibit the motor control operation by the adjustment operation lever 1 〇 I -18 - 201002199. When the temperature flag F S is not in the ON state, the process proceeds from step S37 to step S38. It is judged at step S38 whether 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 S4 and the tension mode processing is executed. When the other button is operated, the process proceeds from step S33 to step S4 1, 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 (ON). When the discontinuous flag FP3 is off (OFF), the process proceeds to step S51. When the discontinuous flag FP3 is ON (ON), the process proceeds to step S54. In step S51, the number of stages ST set by adjusting the operation lever 1 〇 1 and the rotational 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 値Vstl of the upper limit speed Vs corresponding to the protection phase STS (an example of the target speed) to be described later. In step S53, it is judged whether or not the speed Vd of the reel 3 exceeds the lower limit 値Vs12 of the upper limit speed Vs of the phase ST or the corresponding protection phase S T S . When the speed control is performed, the lower limit 値V s 11 and the upper limit 値 -19 - 201002199 of the upper limit speed v s are set in each stage S T .

The reason for Vst2 is to stabilize the feedback control so that the load operation ratio does not change when the speed between the two speeds Vstl and Vst2 is changed, and the scream sound that does not cause the load operation ratio to fluctuate frequently. The upper limit 値V st2 and the lower limit 値Vstl are set within, for example, ±10% of the upper limit speed Vst. In step S54, when the load is high, the first protection process for interrupting the operation of the motor 4 is performed, and in the case of high load, the second protection process for decelerating the motor 4 is performed in the case of high load, and the operation is returned to the key input. When the processing 〇 speed Vd is the lower limit 値Vstl is not full, 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 mark FP2 is turned "ON", in order to prohibit the speed increase operation from the guard stage STS decelerating by the second protection process to the high-speed side stage ST, the process proceeds from step S56 to Step S 6 1. In step S61, the set phase S T is determined by the second protection process 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 to ignore the joystick operation prohibiting the speed increase operation. When the set stage ST is set to be equal to or lower than the protection stage 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 (〇FF) to step S57. When the second protection flag FP2 is OFF (OFF), the process proceeds from step S56 to step s7, and the current first duty operation ratio D1 is read. This 〗 〖load work ratio D 1, is changed in memory every time the setting changes -20- 201002199 part l 〇 7. Further, the maximum 値DUst and the minimum 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 judged whether or not the current first duty operation ratio D1 exceeds the maximum 値DUst of the set stage. If it is exceeded, the process proceeds to step S60. The first load operation ratio D 1 sets the maximum 値 DUst. If it is not exceeded, the process proceeds from step S58 to step S59, and only the first load duty ratio is increased by a predetermined increment DI (e.g., 1%) to step S53. In addition, the load ratio of the high stage (ST = 31) is set to 100%, and the maximum 値DUst is set to 85% or less in the previous stage (ST = 1 in 30). When the speed V is greater than the upper limit 値Vst2, the current first load operation ratio D 1 is read from step S53 to step S63. This first load operation ratio D1 is also the same as step S57. In step S64, it is judged whether or not the first duty operation ratio D 1 is lower than the final value D L s t of the set phase. If it is lower than the case, the process proceeds to step S6 6 to set the minimum 値D L s t at the first duty ratio D 1 . If it is not lower than the above, from step S6 4 to step S65, only the first load duty ratio D1 is decreased by a predetermined division DI (for example, 1%) to step S54. [First Protection Process] The first protection process in step S 54 is a motor protection process that is effective when the speed mode is 5 to 3 1 'The motor 4 is under high load and the ON/OFF is interrupted. The current flow prevents the burnout of the motor 4 from being suddenly set at D1, but will be shifted by 1 and then reduced by ST when the loss is 21 - 201002199. In the first protection process, the current 値 flowing to the motor 4 (that is, the load acting on the motor 4) is the first current 成为 which is 50% or more and 90% or less of the maximum current 値 (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 (ΟΝ/OFF) flows to the motor 4 for intermittent control. In addition, when the speed is the second speed (for example, the upper limit speed of the 1st stage (ST = 1 3)) 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 is returned. control. Specifically, the rotational speed Vd and the load current 値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 S7, and the current 値Id of the motor 4 detected by the current detecting unit 108a is determined, that is, whether the load is the first current or not. 1 2A or more. When the current 値Id is 1 2A or more, the process proceeds to step S73. When 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 FP 1 is not turned ON (ON), the process proceeds to step S74. When the first protection flag FP 1 is already ON (ON), the steps S 7 3 to S 7 7 are skipped and the process proceeds to step S 7 8 . In step S74, the timing for measuring the first predetermined time t2 is determined. Whether T2 has been turned ON (ON). When the timer T2 is not ON (ON) -22- 201002199, the process proceeds to step S75 to turn on the timer T2 (〇N) to step S76. When the timer T2 is ON (ON), the process proceeds to step S76 by skipping step S75. In step S76, it is judged whether or not the timer T2 has expired and is turned off (OFF). That is, it is judged whether or not the load and the speed have passed from the predetermined condition for one minute. When it is determined that the timer T2 has expired, the process proceeds to step S77 to make it clear that the first protection flag FP1 for satisfying the first condition is turned "ON". In step S78, an on/off current is flown to the intermittent control process in which the motor 4 performs driving. In step S709, it is judged whether or not the load is the second current 比 which is larger than the first current 値, i.e., 15 A (amperes) or less. When the load is 1 5 A or less, the process proceeds to step S 8 0. In step S80, it is judged whether or not the speed Vd is equal to or higher than the upper limit speed Vs 1 3 of the 13th step (ST13). When the speed Vd is equal to or higher than the upper limit speed Vs 1 3 , it is determined that the first protection mark FP 1 is off (OFF) without requiring protection. When the first protection mark FP1 is OFF (OFF), the motor 4 is controlled by the 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 processing. [Intermittent processing] In the interrupt processing of step S78, it is determined in step S9 1 of Fig. 2 whether or not the timer T3 for measuring the second predetermined time (e.g., 15 seconds) from the discontinuous processing ends. In step S92, it is determined whether or not the timer T3 is turned "ON". When the timing device T3 is not turned ON (ON), the time shift is -23-201002199. The routine proceeds to step S99 to turn on the timer T3 (〇N) and then shift to step S93. When the timer T3 is already turned on (〇N), the process proceeds to step S93 by skipping step S99. In step S93, the temperature of the motor drive circuit 1 〇 8 , that is, the temperature Td δ of the motor 4 is sold 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 pre-expansion temperature (e.g., 50 degrees Celsius to 7 degrees Celsius is preferable, and in this embodiment, 60 degrees). In this intermittent control, the conduction (〇N) time and the OFF (0 F F) time of the motor 4 are changed by the second predetermined temperature. That is, when the temperature is low, the conduction (〇 N ) time is longer than the OFF (〇 F F ) time, and when the temperature is high, the cooling period is set to make the OFF (〇FF) time longer than the ON time. When the temperature Td is less than 6 degrees Celsius, the process proceeds from step S94 to step S95. In step S95, the motor 4 is turned on (〇N) time tn1 (e.g., 600 to 100 〇 m seconds, 750 msec in this embodiment). In step S96, the motor 4 is turned OFF (OFF) time tfl (e.g., 35 〇 to 75 〇 m seconds shorter than time tn1, in this embodiment, 50,000 m seconds), and returns to the first protection process. When the temperature Td is 60 degrees or more, 'Move to step S9 7 to turn on the motor 4 (Ο N ) time t η 2 (for example, 6 〇 0 to 1 〇〇 () m seconds, which is 75 此 in this embodiment. m seconds). In step S96, 'turn off the motor 4 (OFF) time tfl (for example, 80 〇 to 12 〇〇 m seconds longer than the time tn1, in this embodiment, 1 〇〇〇 111 seconds), return to the first protection. deal with. When the timer T 3 is the end of the time, that is, if the intermittent processing is over 15 seconds or more, the process proceeds from the step S9 1 to the step S 1 〇〇 ' to determine whether or not the intermittent flag FP3 is ON (〇N). The discontinuous mark FP3 is a mark that is turned on (〇N) when the second predetermined time elapses as described above -24 - 201002199. When the discontinuous flag FP 3 is not ON (ON), the process proceeds to step S 1 〇 1 to make the discontinuity flag FP3 ON. In step S102, the motor 4 is turned off (OFF). When the discontinuous flag FP3 is already on (on), steps S101 and S102 are skipped. In step S103, it is judged whether or not the timer T4 has been turned ON (ON). The timer T4 is a timer for measuring the time after the motor 4 is turned off (Ο F F ) to recover the rotation of the motor 4, and when the passage of 30 seconds elapses, the time is turned off (〇 F F ). When the timer T4 is not ON (ON), the process proceeds to step s 1 04 to turn on the timer T4 (ON). When the timer T4 is already on (on), the step S1 0 4 is skipped. In step S1 0 5, it is judged whether or not the timer T4 is turned off (Ο F F ). When the time has elapsed, the process proceeds to step s 1 0 6. In order to make the motor 4 operate, the discontinuity flag FP3 is turned OFF (OFF) and returns to the first protection process. Thereafter, when the adjustment lever 1 〇 1 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 S5 5 is a process of decelerating the motor 4 when the load acting on the motor 4 becomes high when the speed mode is equal to or higher than eight stages. In the second protection process, the current detected by the current detecting unit i 8a is detected in the state of the second current 値I s (for example, 1 5 A ) or more for the fourth predetermined time. The first condition of t5 (for example, 3 seconds) corresponds to the target speed of the upper limit speed which is at least one stage lower than the detected rotation speed (the second stage is set in this embodiment). 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 the target speed by the predetermined amount of the first load (for example, 〇·5 A). The upper limit speed is set to at least one higher stage by the 1 second interval. In the second protection process, in step Sill of Fig. 13, the rotational speed Vd, the load current 値Id, the current number of segments ST, and the protection phase S T S set by the second protection process are read. In step S1 1 2, it is judged whether or not the current stage ST is 8 or more. When the stage ST is 8 or more, the process proceeds to step S 1 1 3 . When the stage s T is 8 is not full, it is not processed and returns to the speed mode processing. In the step s 1 1 3, it is judged whether or not the current 値I d indicating the load is equal to or higher than the third current 値IS. When the current 値I d is equal to or greater than the third current 値 (e.g., < 1 5 A ) I s , the process proceeds to step S 1 14, and it is determined whether or not the timer T5 has expired. The timer T5 is for measuring the predetermined time 15 for determining the first condition required for the second protection processing. The timer T 5 is moved to the step S丨丨5 when the time is not over, and it is judged whether or not the timer T5 has started (on). When the timer T5 is not conducting (Ο N ), the process proceeds to step s丨丨6 to turn on the timer τ 5 (ON) and start timing. When the timing τ5 is ON, the jump -26-201002199 goes to the step S117 via the step S116. The timer T5 is a case where the time is over, that is, when the load is such that the above condition continues for the first condition of 3 seconds or longer, the process proceeds from S 1 14 to step s 1 1 7 . In step S1 17, it is judged whether or not the protection STS is 8 or more. In this second protection process, the 7 stages do not decelerate. Therefore, in the second protection process, if the protection phase STS is not in the stage, the process returns to the speed mode process. When the protection S T S is equal to or greater than 8 stages, the process proceeds to step s 1 1 8 . In s 1 18, whether or not the second protection flag FP2 that satisfies the first condition and is judged to be turned on at the time of the first deceleration processing is turned "ON". When the second security FP2 is not turned "ON", the process proceeds to step S119 to turn on the second security FP2 (ON). In step S120, it is judged whether or not the protected STS is 8 segments. In this embodiment, since the protection phase STS is 9 or more in the case where the 7-segment or less is not reduced, the transition to S 1 2 1 sets the protection phase STS to the stage STvd from the upper limit speed corresponding to the current rotational speed | In the lower two-stage stage (STvd-2), the current speed Vd is set to be lower than the highest upper limit stage. When the protection phase STS is eight stages, the process proceeds from step S1 22 to a stage (STvd-Ι) lower than the upper limit speed segment STvd corresponding to the current rotational speed Vd, that is, the protection phase is set to seven stages. In the middle of the second protection process (the second protection target is turned ON), if the operation lever 1 〇1 is adjusted so as to be in the protection stage STS or more, the speed pattern processing step S6 1 of the first map is operated. The stage ST is beyond the protection stage STS. 1 5A Steps and stages: Full 8 stage steps (ON protection standard stage speed, step? Vd ° Speed step STS is recorded as operation step -27- 201002199 It is ignored that the high-speed operation above the protection stage STS cannot be performed. In step S1 23, it is judged whether or not the timer T6 has expired. This timing T6 is decelerated from the initial time, in order to wait for a predetermined time (for example, 3 seconds) When the timer T6 is the end of the time, the timer T6 is shifted to the step s 1 2 6, and the current first load, that is, the current 値Idn, is read in and returned to the speed mode processing. The variable η is initially set to 1. When the timer Τ6 has not expired, the process proceeds to step s-24, and it is determined whether or not the timer Τ6 has been turned ON (ON). When the timer T6 is not turned ON (ON) , move to step S12 5 Turn on the timer T6 (ON) and start timing. When the timer T6 is already ON (ON), skip the step s 1 2 5 and move to the step s 1 2 6 . Here, not from the second stage Deceleration immediately reads in the current 値 but waits for 3 seconds. If the current is read immediately after the deceleration of the second stage, the current 値 will be unstable. It is judged that the current current 读 (current load) Id is read. If the third current 値Is is not full, 'the flow proceeds from step S1 1 4 to step S1 36. In step S136, the second protection flag FP2 is turned off (OFF), and the second protection process is returned to the speed mode. Therefore, the 'protection phase STS is also reset to 31 segments. If it is judged that the second protection flag FP2 is ON ('transfer from step S1 1 9 to step S1 2, 7, the timing device T 7 is judged. Whether or not the time is over. This timing T7 is a timing device that is assembled after waiting for a predetermined time (for example, '1 second) after detecting the first load, that is, the current 値Idn. The timing T 7 is time. In the case of the end, the process moves to step s 1 3 0 'to increase the variable η by 1. The timer T 7 is when the time is not over. 'Move to step -28 - 201002199 S128 to determine if the timer T7 is turned on (〇N). When the timer T7 is not conducting (Ο Ν), 'Move to step S丨2 9 to make the timer τ 7 Turn ON (ON) and start timing. When the timer T7 is already ON, skip the step s 1 2 9 and move to the step s 1 3 0. In the step s 1 3 1 , the 2nd at that time The load is also the current 値Idn read in. In step S1 3 2, it is judged whether or not the read second load is the current 値 I d η which is equal to or less than 7 〇 % of the third current 値I s . When the current 値I d η is equal to or less than 7〇% of the third current 値, 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 値Idn is over 70% of the third current 値I s , the process proceeds to step S 1 3 3 . In step S1 3 3, it is judged whether or not the second load (Idn) read now is 1 A or more larger than the first load (Id (η-1)) read in the previous deceleration. When the load is increased by 1 A or more, the process proceeds to step S1 3 4, and the determination of the second load at the next time point after 1 second becomes the current current 値Idn of the first load as a comparison control.値 decreased by 0.1 A. 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 (I d η ) is not larger than the first load (I d ( η -1 )) read in the previous deceleration, the process proceeds from step S 1 3 3 to step S 1 3 7 . In step S1 37, it is judged whether the second load, that is, the current 値Idn, reaches the maximum current 流动 (for example, 18 A) flowing to the motor 4. When the maximum current 到达 is reached, 'Move to step S 1 3 4 for deceleration processing. If it is not reached, go to step S 1 3 8 ° -29- 201002199. In step S 1 3 8 , judge the first load ( Whether Id ( η - 1 )) is greater than the second load (Idn) by 0.5 A 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 S1 3 9, and the stage ST is set to a stage higher than the stage STV d corresponding to the upper limit speed of the current rotational speed Vd. The stage (STV d + 1) returns to the speed mode processing. When the increase of the second load is less than 1A' or the first load is less than 0.5 A, the process is returned to the speed mode without any processing. In the second protection process, the high load is satisfied. In the state, once the speed of the motor 4 is decelerated to an upper limit speed that is at least one stage lower than the current rotational speed, the current flowing to the motor 4 is reduced, and the excess current does not flow to the motor 4. Further, if the load is further reduced, the rotational speed of the motor is increased. When 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 speed control of the motor until the upper limit speed is reached, 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 of 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 ignored. Therefore, in the second protection process, the protection phase STS is not accelerated to the high speed side. [Tension Mode Processing] -30- 201002199 In the tension mode processing of step S30, the number of stages ST set by adjusting the operation lever 1 〇1 and the current detecting unit 1 are performed in step S1 4 1 of Fig. 14 The torque of the detection result of 08a is read by the tension Qd of the wire diameter correction. In step S1 42, it is judged whether or not the tension Qd is less than the lower limit 値Qstl of the upper limit tension Qs of the corresponding stage ST. In step S143, it is judged whether or not the tension Qd exceeds the lower limit 値Qst2 of the upper limit tension Qs of the corresponding stage S T . Further, when the tension control is performed, the lower limit 値Qstl and the upper limit 値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 Qstl and Qst2 fluctuates as in the speed mode. The work ratio is not generated in frequently changing screams, and the feedback control is stable. The upper limit 値Qst2 and the lower limit 値Qstl are set within, for example, ± 1 〇 % of the upper limit tension Qst. In step S 144, it is judged whether or not the phase ST is the 3 1 segment of the highest segment, and in the case of the 3 1 phase, the process proceeds to the step S146, and the first protection process shown in Fig. 1 is executed. When the stage S T is other than the 3 1 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 the case where the lower limit 値Qstl is not full, the process proceeds from step S142 to step S147. In step S147, the current second load operation is read in comparison with D4. 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 D 4 is increased by a predetermined increment DI (e.g., 1%) to step S143. This is continued until the tension Qd exceeds the lower limit 値Qstl. When the tension Qd is beyond the upper limit 値Qst2, the process proceeds from step S143 - 31 - 201002199 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 S148, only the second load duty ratio D4 is decreased by a predetermined minus point DI (for example, 1%) to step S1 4 4 . This is continued until the tension Qd is lower than the upper limit 値 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 値 (tension) is determined at each stage ST. [Third Protection Process] The third protection process in step SM5 is a motor protection process that is effective when the stage ST is 5 to 30, and is changed to the tension mode because it is slightly the same as the first protection process for the speed mode. In the third protection process, the current 値 flowing to the motor 4 (that is, the load acting on the motor 4) is the first of 50% or more and 90% or less of the maximum current 値 (for example, 18 A) flowing to the motor. When the current 値 (for example, 1 1 A) is in the third state for a predetermined period of time (for example, preferably 3 sec to 60 sec, in this embodiment, 45 sec.), the ON/OFF interrupt is performed. The current flows to the second intermittent control of the motor 4. 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 S166, and the current 値Id of the motor 4 detected by the current detecting unit 108a is determined, that is, whether the load is the first current or not. It is 1 1 A or more. When the current 値Id is 1 1 A or more, the process proceeds to step S 1 62, and -32-201002199. If the third condition is satisfied, it is judged whether or not the third protection of ON is already ON. In the case where the third protection mark FP4 is not ), the process proceeds to step S136. When the third protection flag is turned ON (ON), the step S 1 6 3 to the step S167 are skipped. In step S1 63, it is judged whether or not the timer T8 for measuring the elapsed time t8 from the current 値id has been turned on (when the timer T8 is not turned ON), the process proceeds to step S164, and T8 is turned ON (ON). The timer T8 is already turned ON (ON). Step S164 is shifted to step S165. In step S165, the timer T8 is turned off (OFF). That is, it is judged whether or not 45 minutes have elapsed after the predetermined condition. When it is finished, the process proceeds to step S1 66 to make the third condition third protection flag FP4 to be turned ON. In step S167, the current of the on/off (ΟΝ/OFF) is flown to the motor 4 to control the process. This discontinuous process is the process shown in Fig. 1 in the case of the speed mode. In step S168, it is judged that the fourth current 値 whose load is 3 is smaller than 10 A. The case is shifted under load. Go to step s 1 6 9. In step s 1 6 9 , protection is required and the third protection mark FP4 is turned off (〇ff). When the guard mark FP 4 is off (Ο FF ), the adjustment pulse is returned. The motor 4 can be operated up to the operation start position.

The determination in steps S160, 161, 165, and 168 is NO, and returns to the tension mode processing. The i mark FP4 is turned on (ON FP4 is ON after S166 shifts 1 1 A). When the timer is being used, the judgment is not satisfied. 3rd guarantee: When lever 1 〇1 is used -33- 201002199 [Each operation mode processing] In each operation mode processing of step S8, it is judged whether or not the rotation direction of the reel 3 is in step S 17 7 of Fig. 16 Speak out the direction for the line. In this judgment, it is judged that any of the Hall (H al 1 ) elements of the reel sensor 1 〇 2 is pulsed first. It is judged that the rotation direction of the reel 3 is the line discharge direction. The flow proceeds from step S171 to step S172. In step SN2, each time the number of rotations of the cylinder is reduced, the water depth is calculated by reading from the number of revolutions of the drum and storing it in the memory unit. This water depth is displayed by the display processing of step S2. In step S1 73, it is judged whether or not the obtained water depth coincides with the bottom position, and whether the quasi-bait reaches the bottom. The bottom position is set to the memory unit 1 〇 7 by pressing the forget button Μ B when the bait reaches the bottom. In step S1 7 4, it is determined whether or not it is another mode such as a learning mode. When it is not in other modes, the processing of each action mode ends and returns to the main routine. If the water depth is the same as the bottom position, the process proceeds from step S1 7 3 to step S 1 7 5 ′ to notify the bait to reach the bottom and let the buzzer 丨〇 6 call. In the case of other modulo, the process proceeds from step S147 to step S178, and the other mode is designated. When it is judged that the rotation of the reel 3 is the wire winding direction, the flow proceeds from step S1 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 the steps. In step S178, it is judged whether or not the water depth coincides with the edge stop position. When it is not taken up to the rim stop position, return to the main routine. When the rim stop position is reached, the 7 of the 话 〇 〇 〇 〇 7 7 被 被 被 被 被 被 被 被 被 被 被 被 被 被 被 34 34 34 34 34 34 34 34 34 34 34 34 34 34 34 34 34 34 34 34 34 34 34 34 34 34 34 34 34 34 34 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 when, for example, the reel 3 is stopped for a predetermined time or longer within a water depth of 6 m. [Other Embodiments] (a) In the foregoing embodiment, the specific numbers of those in which various currents 値 and 値 are set are merely examples, and the present invention is not limited to those.
