In step S3, judged whether the key input operation, if having, then jump to step S7 from this step S3.In step S7, carry out key input shown in Figure 9 and handle.In step S4,, then jump to step S8 from step S4 if judge spool 3 rotating.In step S8, carry out each pattern shown in Figure 16 and handle.In step S6, if other processing instructions are arranged, then jump to step S9 from step S6, carry out other processing instructions.

＜overtemperature protection is handled 〉

The overtemperature protection of step S5 is handled and is meant: if the temperature (that is, the temperature of motor 4) of motor drive circuit 108 is more than 90 degree, then close the processing of motor 4.When carrying out the overtemperature protection processing, as shown in Figure 8, in step S11, read the temperature of motor drive circuit 108 according to the output valve of temperature sensor 103.Because the temperature of motor drive circuit 108 and the temperature of motor 4 are roughly proportional, so can measure the temperature of motor 4 by the temperature that detects motor drive circuit 108.In step S12, judge whether the temperature of motor drive circuit 108 surpasses first set point of temperature (for example, preferably being roughly 85 ℃～95 ℃, is 90 ℃ in the present embodiment).When the temperature of motor drive circuit 108 surpasses 90 ℃, then jump to step S13 from step S12.In step S13, judge whether the temperature sign FS that can open opens when temperature surpasses 90 ℃ first.If temperature sign FS does not open, then jump to step S14, FS opens with the temperature sign, jumps to S15 then.If temperature sign FS opens, then skips steps S14 directly enters step S15.In step S15, close motor 4, return main program then.Thus, can prevent that motor 4 from being burnt out when overload.

If the temperature of motor drive circuit 108 is below first set point of temperature, then jump to step S16 from step S12.In step S16, judge whether temperature sign FS opens.If do not open, then return main program.If open, then jump to step S17 from step S16, judge whether the temperature T d that measures drops to below second set point of temperature lower than first set point of temperature (for example, preferably being roughly 75 ℃～85 ℃, is 80 ℃ in the present embodiment).By above judgement,, no problem overtemperature protection finishes if just handling.If the temperature T d that measures surpasses 80 ℃, then return main program, if the temperature T d that measures is below 80 ℃, then enter step S18 from step S17.In step S18, judge whether timer T1 opens.Timer T1 is used to confirm described temperature T d is whether the following state of second set point of temperature has continued stipulated time t1 (for example, being preferably 20～40 seconds, is 30 seconds in the present embodiment).If timer T1 does not open (startup), then enter step S19, open timer T1.If timer T1 opens, then skips steps S19 directly enters step S20 from step S18.In step S20, judge that whether timer T1 is to the time.If not to the time, then return main program.If to the time, that is, described temperature T d is that the state below 80 ℃ has continued more than 30 seconds, thinks that then overload eliminates and enter step S21, and closing temperature sign FS finishes overtemperature protection and handles.The overtemperature protection processing as long as make adjusting lever 101 turn back to initial operation position (grade ST=0), just can make motor 4 move again after finishing.

The input of＜key is handled 〉

In the input of the key of step S7 is handled, as shown in Figure 9, judge at step S31 fishing line reel control part 100 whether menu button MB grows and pressed more than 3 seconds.In step S32, judge whether adjusting lever 101 is operated from the initial operation position.In step S33, the operated situations of other keys such as fish layer store button TB, confirming button DB and menu button MB are clicked have been judged whether.

When menu button MB is grown on time, then jump to step S34 from step S31.In step S34, judge whether control model is velocity mode.If velocity mode then jumps to step S36 from step S34, control model is set to tension mode; If tension mode then jumps to step S35 from step S34, control model is set to velocity mode.

If judge adjusting lever 101 when position in addition, initial operation position (ST=0) is operated, then jump to step S37 from step S32.In step S37, judge whether temperature sign FS opens.If opened, then jump to step S33, forbid the control of being undertaken by 101 pairs of motors of adjusting lever.If temperature sign FS does not open, then jump to step S38 from step S37, in step S38, judge whether to be velocity mode.If velocity mode then jumps to step S39 from step S38, the execution speed mode treatment; If tension mode then jumps to step S40 from step S34, carry out tension mode and handle.In step S33, if having judged other keys is operated, then jump to step S41 from step S33, carry out corresponding the processing according to operated key.

＜velocity mode is handled 〉

In the velocity mode of step S39 was handled, fishing line reel control part 100 was by control motor 4, so that the rotating speed of spool 3 reaches the speed limit value that sets grade.According to the winding radius of fishing line on spool 3, the speed limit value of spool 3 is revised to some extent, therefore to the control of motor 4, comes down to will accomplish with constant speed fishing line to be wound on the spool 3.

As shown in figure 10, in step S50, fishing line reel control part 100 judges whether interrupted sign FP3 opens.Should represent that be in the interrupted processing procedure described later this moment by interrupted sign FP3.If interrupted sign FP3 closes, then jump to step S51 from step S50.If interrupted sign FP3 opens, then jump to step S54 from step S50.

In step S51, read the number of degrees ST, the protection class STS described later that set by adjusting lever 101 and the rotating speed Vd of the spool 3 of calculating according to the output valve of spool sensor 102.In step S52, fishing line reel control part 100 is judged the rotating speed Vd of spool 3 whether less than the lower limit Vst1 of speed limit value (interval) Vs, and this speed limit value Vs is grade ST or the pairing higher limit of protection class STS described later.In step S53, whether the outpace higher limit Vst2 of higher limit Vs of the rotating speed Vd that judges spool 3, this speed limit value Vs is grade ST or the pairing higher limit of protection class STS described later.When speed is controlled, why speed limit value Vs for each grade ST is provided with its lower limit Vst1 and higher limit Vst2, be because as long as speed changes between these two limit value Vst1, Vst2, dutycycle just can not change, the unstable region of dutycycle frequent variations (ワ ウ リ Application グ) just is not easy to form like this, and FEEDBACK CONTROL can more stably be carried out.This higher limit Vst2 and lower limit Vst1 are set in the scope for example ± 10% of speed limit value Vs.

In step S54, be in high load condition as if motor 4, then carry out first protection of motor 4 intermitten operations and handle, in step S55,, then carry out the second protection processing that motor 4 runs slowly if motor 4 is in high load condition, the return key input is handled then.

In step S52, if speed Vd less than described lower limit Vst1, then jumps to step S56 from step S52.In step S56, judge whether the second protective emblem FP2 that can be opened is opened when second protection described later is handled.If opened, then jump to step S61 from step S56, quicken because of the protection class STS of adjusting lever after being decelerated from second protection is handled moves to the grade ST of the higher side of speed to forbid motor.In step S61, judge whether the grade ST that sets surpasses the protection class STS that sets in the second protection processing.If surpass, then jump to step S53, thereby no matter the operating state of adjusting lever how, does not allow motor to quicken from step S61.If the grade ST that adjusting lever sets is below the protection class STS, then jump to step S62 from step S61, in step S62, close the second protective emblem FP2, jump to step S57 then.

In step S56, if the second protective emblem FP2 is in closed condition, then jump to step S57 from step S56, read the first current dutycycle D1.This first dutycycle D1 can be deposited in storage part 107 after every setting once.Under each grade ST, be set with the maximum DUst and the minimum of a value DLst of dutycycle, when under each grade ST, setting the first dutycycle D1 first, for example can it be set to maximum DUst and middle ((DUst+DLst)/2) of minimum of a value DLst.In step S58, judge whether the first current dutycycle D1 surpasses the maximum DUst that sets grade.If surpass, then jump to step S60 from step S58, the first stop sky is set at maximum DUst than D1.If do not surpass, then jump to step S59 from step S58, make the first dutycycle D1 increase the increment DI (for example 1%) of regulation, jump to step S53 then.The dutycycle of highest ranking (ST is 31) is set at 100%, and for the grade before the highest ranking (ST be more than 1 below 30), the maximum DUst of its dutycycle is set in below 85%.

If speed Vd surpasses higher limit Vst2, then jump to step S63 from step S53, read the first current dutycycle D1.This action of reading the first dutycycle D1 is identical with step S57.In step S64, judge that the first current dutycycle D1 whether less than the minimum of a value DLst that sets grade, if the first dutycycle D1 less than minimum of a value DLst, then jumps to step S66 from step S64, is set at minimum of a value DLst with the first dutycycle D1.If the first dutycycle D1 is not less than minimum of a value DLst, then jump to step S65 from step S64, the decrement DI that makes the first dutycycle D1 reduce to stipulate jumps to step S54 then.

＜the first protection is handled 〉

Among the step S54 first protection is handled and is meant: grade ST is that effective patterns protection in 5～31 o'clock is handled under velocity mode; when high capacity acts on the motor 4; then break-make is controlled motor 4 (motor 4 opens or cuts out), and making its electric current is interrupted current, to prevent that motor 4 from being burnt out.First protection when motor 4 becomes first state, then begins to carry out intermittent controlled in handling, even the electric current that flows through motor 4 is off and on interrupted current.This first state is meant: first current value continued for first stipulated time (for example, being preferably 0.5～2 second, is 1 second in the present embodiment), and spool 3 is at the state of the following rotation of first speed (for example, the speed limit value under the grade 12 (ST=12)).This first current value is meant: the current value (that is, act on the motor 4 load) that flows through motor 4 for the lowest high-current value (for example 18A) that flows through motor 4 50% or more and the current value (for example 12A) below 90%.This first speed is meant: the rotating speed below 40% of the speed limit value under the maximal rate grade.When the speed of spool 3 is, then to be judged as load and to reduce, and stop described intermittent controlled during more by the second speed (for example, the speed limit value 13 grades (ST=13) under) of high-speed side than first speed, return normal speed control or tension force and control.

Particularly, as shown in figure 11, in step S69, fishing line reel control part 100 reads rotating speed Vd and load current value Id.In step S70, judge whether current grade ST is more than 5.If grade ST is more than 5, then jump to step S71 from step S70, whether the current value I d that judges the motor 4 of flowing through that current detecting part 108a is detected is more than the 12A, judges promptly whether load current (electric current under the load condition) is more than the first current value 12A.If current value I d is more than the 12A, then jump to step S72 from step S71, in step S72, whether the rotating speed Vd that judges spool is at (below for example for the speed limit value Vst12 under the grade 12 (ST=12)) below first speed.Rotating speed Vd above and spool 3 is below first speed if current value is 12A, then jumps to step S73 from step S72.Whether the first protective emblem FP1 that judgement will be opened when satisfying first condition described later opens.If also do not open, then jump to step S74 from step S73.If open, then skips steps S74～step S77 directly jumps to step S78 from step S73.

In step S74, fishing line reel control part 100 judges whether the timer T2 that is used to measure the first stipulated time t2 opens.If also do not open, then jump to step S75 from step S74, open timer T2, jump to step S76 from step S75 then.If opened, then skips steps S75 directly jumps to step S76 from step S74.

In step S76, judge whether timer T2 is in closed condition to the time.That is, judge that satisfying rated condition from load current and speed whether has begun after one minute.If judge timer T2 to the time, then jump to step S77 from step S76, open the first protective emblem FP1, this first protective emblem FP1 is used for identification and whether has satisfied first condition.In step S78, to carry out intermittently and handle, i.e. break-make control motor 4 is so that its drive current is an interrupted current.In step S79, judge that whether load current is below the second current value 15A (ampere) greater than first current value.If load current is below the 15A, then jump to step S80 from step S79.In step S80, judge that whether speed Vd is more than the speed limit value Vs13 under the grade 13 (ST13).If speed Vd is more than the speed limit value Vs13, then judging does not need motor 4 is protected, thereby closes the first protective emblem FP1 (step S81).When the first protective emblem FP1 is closed, then motor 4 is carried out normal speed control or tension force control.

If the judged result among the step S70,71,72,76,79,80 is a "No", then the return speed mode treatment.

＜interrupted processing the

In the interrupted processing of step S78, as shown in figure 12, whether judge timer T3 to the time by step S91, this timer T3 is used for calculating for second stipulated time (for example 15 seconds) when interrupted processing begins.In step S92, judge whether timer T3 opens.If also do not open, then jump to step S99 from step S92, timer T3 is opened make its action, jump to step S93 then.If open, then skips steps S99 directly jumps to step S93 from step S92.In step S93, read the temperature of motor drive circuit 108, i.e. the temperature T d of motor 4 according to the output valve of temperature sensor 103.Among the step S94, whether the temperature T d that judges motor 4 surpasses first set point of temperature (for example, be preferably more than 50 ℃ below 70 ℃, in the present embodiment be 60 ℃).In this intermittent controlled, it is running time and the shut-in time that the boundary changes motor 4 with first set point of temperature.That is, when temperature is low, be longer than the shut-in time running time, when temperature is higher, then make the shut-in time be longer than running time, so that cooling period to be set.In step S94, if temperature T d less than 60 ℃, then jumps to step S95 from step S94.In step S95, make motor 4 operation (energising) time tn1 (for example, below 1000 milliseconds, in the present embodiment being 750 milliseconds more than 600 milliseconds), jump to step S96 then.In step S96, make motor 4 close (outage) time tf1 (for example, shorter, be more than 350 milliseconds below 750 milliseconds, in the present embodiment be 500 milliseconds) than time tn1, return first protection then and handle.In step S94,, then jump to step S97 from step S94 if temperature T d is more than 60 degree, (for example make motor 4 operation (energising) time tn2, below 1000 milliseconds, in the present embodiment be 750 milliseconds more than 600 milliseconds), jump to step S98 from step S97 then.In step S98, make motor 4 close (outage) time tf2 (for example, longer, be more than 800 milliseconds below 1200 milliseconds, in the present embodiment be 1000 milliseconds) than time tn2, return first protection then and handle.

In step S91, if timer T3 to the time, promptly intermittently handles through more than 15 seconds, then jump to step S100 from step S91, judge whether interrupted sign FP3 opens.As previously mentioned, indicate that intermittently FP3 is the sign of opening during second stipulated time at interrupted processing continuous service.If interrupted sign FP3 does not open, then jump to step S101 from step S100, will indicate intermittently that FP3 opens, and jumps to step S102 then.In step S102, close motor 4.In step S100, if interrupted sign FP3 opens, then skips steps S101, step S102 directly jump to step S103 from step S100.In step S103, judge whether timer T4 opens.Timer T4 is used to calculate the time that motor 4 cuts out and makes motor 4 recover the timer that rotates, and when from closing motor 4 when beginning through 30 seconds, timer T4 can be because of closing to the time.If timer T4 does not open, then jump to step S104 from step S103, T4 opens with timer.If timer T4 opens, then skips steps S104 directly jumps to step S105 from step S103.In step S105, judge whether timer T4 closes to the time.If timer T4 to the time, then jumps to step S106 from step step S105, close interrupted sign FP3, return first protection then and handle, motor 4 can be moved.Afterwards, make after the adjusting lever 101 return starting positions, motor 4 just can move.

This first protection is intermittently rotated by making the motor 4 under the high load condition in handling, and can prevent that overcurrent from flowing through motor 4 and causing its heating.And if the load of motor 4 is enough little, then motor 4 can be with the speed limit value rotation of setting.Therefore, just can prevent that under the situation that does not reduce the fishing line reel performance motor 4 from being burnt out.

＜the second protection is handled 〉

Second protection of step S55 only handles that to be in velocity mode and grade at motor 4 be just can carry out under the duty 8 or more, and when the electric current of the load on acting on motor 4 uprised, this second protection processing can make motor 4 decelerations.During second protection is handled; when the detected load current of current detecting part 108a satisfies first condition; promptly; load current be the above state continuance of the 3rd current value I s (for example 15A) the 4th stipulated time t5 (for example 3 seconds), then set with the speed limit that is lower than at least one grade of detected rotating speed (being two grades in the present embodiment) and be worth corresponding target velocity.Then, to after the target setting speed through first load (electric current under first load condition) of the 5th stipulated time (for example 3 seconds) with compare through second load (electric current under second load condition) of the 6th stipulated time (for example 1 second) again, when the big ormal weight of second duty factor, first load (for example 1A), then every through just target velocity being set at the speed limit value of a low grade in one second, when second load current during, then every through just target velocity being set at the speed limit value of a high at least grade in one second than the little ormal weight of first load current (for example 0.5A).

In second protection is handled, as shown in figure 13, in step S111, read the protection class STS that rotating speed Vd, load current value Id, current grade ST and second protection are set in handling.In step S112, judge whether current grade ST is more than 8.If more than 8, then jump to step S113 from step S112.If less than 8, then do not carry out any processing, and the return speed mode treatment.In step S113, judge whether load current value Id is more than the 3rd current value I s.If the 3rd current value (for example 15A) then jumps to step S114 from step S113 more than the Is, judge that whether timer T5 is to the time.Timer T5 is the timer that is used for computational rules time t5, and this stipulated time t5 is used for judging whether the first condition that need carry out the second protection processing satisfies.If timer T5 is to the time, then jump to S115 from step S114, judge that timer T5 is whether opened and move.If timer T5 does not open, then jump to step S116 from step S115, timer T5 is opened and makes its operation.If timer T5 opens, then skips steps S116 directly jumps to step S117 from step S115.

If timer T5 is to the time, that is, load current is that the above state continuance of 15A satisfied first condition more than 3 seconds, then jumps to step S117 from step S114.In step S117, judge whether protection class STS is that grade is more than 8.In this second protection is handled,, then do not slow down if protection class STS is a grade below 7.Therefore, in second protection is handled,, protection class STS handles the return speed mode treatment if, then finishing this second protection less than grade 8.If protection class STS is a grade more than 8, then jump to step S118 from step S117.In step S118, judge whether the second protective emblem FP2 that can open is opened when satisfying first condition and first deceleration processing.If when not opening, then jump to step S119, sign is handled in second protection opened from step S118.In step S120, judge whether protection class STS is grade 8.In the present embodiment; because protection class STS does not then slow down when to be grade 7 following; so if protection class STS is that grade is more than 9; then jump to step S121 from step S120; protection class STS is set in the grade (STvd-2) of hanging down two grades than grade STvd; wherein, grade STvd is the grade of the current pairing speed limit value of rotating speed Vd.Particularly, protection class STS is set than low two grades of the pairing grade of maximal rate higher limit below the current speed Vd.If protection class STS is a grade 8, then jump to step S122 from step S120, protection class STS is set in the grade (STvd-1) of hanging down a grade than the grade STvd of the current pairing speed limit value of rotating speed Vd, promptly be set in grade 7.In the implementation that second protection is handled (second protective emblem is opened); when operation adjusting lever 101; make its grade be this second protection class STS when above; then as shown in figure 10; in the step S61 that velocity mode is handled; if the grade ST after the operation surpasses protection class STS, then ignore aforesaid operations, do not allow adjusting lever 104 to the side operation higher than the speed under the protection class STS.

In step S123, judge that whether timer T6 is to the time.This timer T6 is used for keeping to begin the back from initial deceleration and waits for the stipulated time (for example 3 seconds).If timer T6 to the time, then jumps to step S126 from step S123, read the first load current value Idn of this moment, then the return speed mode treatment.Variable n is beginning to be set to 1 most.If timer T6 not to the time, then jumps to step S124 from step S123, judge whether timer T6 opens.If timer T6 does not also open, then jump to step S125 from step S124, T6 opens with timer.If timer T6 opens, then skips steps S125 directly jumps to step S126 from step S124.In the present embodiment, after the deceleration of having carried out two grades, just do not read current value immediately, read this current value again but waited for for three seconds, its reason is: the current value after the deceleration of just having carried out two grades is also unstable, and should not read immediately this moment.

In step S113, then jump to step S136 less than the 3rd current value I s from step S113 if judge current current value (electric current under the current load condition) Id that reads.In step S136, close the second protective emblem FP2, stop second protection and handle, then the return speed mode treatment.Thus, protection class STS is reset to grade 31.

If it is opened to judge the second protective emblem FP2, then jump to step S127 from step S118, judge that whether timer T7 is to the time.This timer T7 is used for keeping waiting for the stipulated time (for example 1 second) after detecting the first load current value Idn.If timer T7 to the time, then jumps to step S130 from step S127, make variable n increase 1.If timer T7 not to the time, then jumps to step S128 from step S127, judge whether timer T7 opens.If also do not open, then jump to step S129 from step S128, timer T7 is opened and makes its operation.If open, then skips steps S129 directly jumps to step S130 from step S128.In step S131, read the second load current value Idn of this moment.

In step S132, judge whether the second load current value Idn that reads is below 70% of the 3rd current value I s.If current value I dn is below 70% of the 3rd current value, then jump to step S136 from step S132, close the second protective emblem FP2, stop second protection and handle.If current value I dn surpasses 70% of the 3rd current value I s, then jump to step S133 from step S132.In step S133, judge whether the difference of first load current value (Id (n-1)) that current second load current value (Idn) that reads is read when slowing down before with this is more than the 1A.If load current increases more than the 1A, then jump to step S134 from step S133, make in the judgement that second load current after a second is carried out the current current value I dn decline 0.1A of first load current value of object as a comparison.In step S135, grade ST is set at grade (STvd-1), this grade (STvd-1) is than grade STvd low a grade, the return speed mode treatment then of the pairing speed limit value of current rotating speed Vd.

In step S133, if more than the big 1A of first load current value (Id (n-1)) that second load current value (Idn) was read when slowing down before unlike this, then jump to step S137 from step S133.In step S137, judge that lowest high-current value that whether the second load current value Idn reach motor 4 (for example, 18A).If the second load current value Idn reaches lowest high-current value, then jump to step S134 from step S137, motor 4 is slowed down, if the second load current value Idn does not reach lowest high-current value, then jump to step S138 from step S137.

In step S138, judge whether first load current value (Id (n-1)) and the difference of second load current value (Idn) are more than the 0.5A.If first load current value (Id (n-1)) is more than the 0.5A with the difference of second load current value (Idn), be that load current is when reducing, then jump to S139 from step S138, grade ST is set at grade (STvd+1), this grade (STvd+1) is than the high grade of grade STvd of the pairing speed limit value of current rotating speed Vd, return speed mode treatment then.If second load current value increased less than 1A, and second load current value only reduced less than 0.5A, then do not carry out any processing, return speed mode treatment.

During this second protection is handled; when becoming the high load condition that satisfies first condition, then reduce the speed of motor 4, make its speed for hang down the speed limit value of at least one grade than the speed drop of this moment; reduce the electric current of the motor 4 of flowing through simultaneously, make in the motor 4 can not have overcurrent.Next, if load further reduces, then the rotating speed of motor 4 increases, if load increases, then the rotating speed of motor 4 further reduces.Therefore therefore, be not prone to overcurrent in the motor 4, before its speed reaches described speed limit value, when continuously the motor galvanization being carried out speed control, the load current of motor is controlled, thereby motor can not burnt out.

As shown in figure 10, in the step S61 that velocity mode is handled, even target setting speed, it is lower than this speed also the speed limit value can be set ground, at this moment, and because of target velocity is cancelled, so be not prone to overcurrent.In addition, when the speed limit value becomes than the higher speed of target velocity, then can not move with the variation of this speed.Therefore, in second protection is handled, can speed change not arrive higher than the speed under the protection class STS.

＜tension mode is handled 〉

In the tension mode of step S40 is handled, as shown in figure 14, read grade ST and the tension force Qd that adjusting lever 101 sets by step S141, this tension force Qd twines radius according to fishing line the moment of torsion that testing result drew of current detecting part 108a is carried out revised tension force.In step S142, judge that tension force Qd is whether less than the lower limit Qst1 of the pairing tension force higher limit of grade ST (interval) Qs.In step S143, judge whether tension force Qd surpasses the lower limit Qst2 of the pairing tension force higher limit of grade ST Qs.When fishing line tension force is controlled, under each grade ST, set lower limit Qst1 and the higher limit Qst2 of tension force higher limit Qs.Identical with velocity mode, when tension force changed between two tension force Qst1, Qst2, dutycycle was constant, the unstable region (ワ ウ リ Application グ) of dutycycle frequent variations can not occur, so can more stably carry out FEEDBACK CONTROL.This higher limit Qst2 and lower limit Qst1 are set in the scope for example ± 10% of tension force higher limit Qs.

In step S144, judge whether grade ST is highest ranking 31, if grade 31 then jumps to step S146 from step S144, carry out first protection shown in Figure 11 and handle.If grade ST is other grades outside the grade 31, then jump to step S145 from step S144, carry out the 3rd protection shown in Figure 15 and handle.When these processing finished, then the return key input was handled.

If tension force Qd less than lower limit Qst1, then jumps to step S147 from step S142.At step S147, read the second current dutycycle D4.This second dutycycle D4 deposits in the storage part 107 after every setting once.In step S148, make the first dutycycle D4 increase the increment DI (for example 1%) of regulation, jump to step S143 then.These steps can continue to carry out, and surpass lower limit Qst1 up to tension force Qd.

If tension force Qd surpasses higher limit Qst2, then jump to step S149 from step S143, read the second current dutycycle D4.This step S149 that reads the second dutycycle D4 is identical with step S147.In step S150, make the second dutycycle D4 reduce the decrement DI (for example 1%) of regulation, jump to step S144 then.These steps can continue to carry out, and are lower than higher limit Qst2 up to tension force Qd.

Compare with the velocity mode processing, in this tension mode is handled, do not carry out the processing that reduces tension force in the second protection processing.This is because the current value (tension force) in the tension mode under each grade ST is fixed.

＜the three protection is handled 〉

It is that grade ST is that effective motor protection in 5～30 o'clock is handled that the 3rd protection of step S145 is handled, be with velocity mode in used first protection handle the processing that is used for tension mode after roughly the same scheme changes.The 3rd protection when motor 4 becomes the third state, then begins to carry out second intermittent controlled in handling: promptly, intermittent controlled motor 4, making its electric current is interrupted current.This third state is meant: first current value (for example continues the stipulated time, be preferably 30～60 seconds, be 45 seconds in the present embodiment) state, wherein, first current value is meant: the current value (promptly acting on the electric current of the load on the motor 4) that flows through motor 4 is 90% the current value (for example 11A) when following more than 50% of the lowest high-current value (for example 18A) that flows through motor.

Particularly, as shown in figure 15, in step S160, judge whether current grade ST is more than 5.If more than 5, then jump to step S161 from step S160, judge whether the current value I d of the detected motor 4 of current detecting part 108a is more than the 11A, judge promptly whether load current (load) is more than the first current value 11A.If current value I d is more than the 11A, then jump to step S162 from step S161, judge whether the 3rd protective emblem FP4 that can open when satisfying the 3rd condition described later opens.If the 3rd protective emblem FP4 does not also open, then jump to step S163 from step S162.If the 3rd protective emblem FP4 opens, then skips steps S163～step S166 directly jumps to step S167 from step S162.

In step S163, judge to be used to measure and whether open above the timer T8 that 11A begins the elapsed time t8 of institute from current value I d.If also do not open, then jump to step S164 from step S162, open timer T8.If open, then skips steps S164 directly jumps to step S165 from step S163.In step S165, judge whether timer T8 is in closed condition to the time.That is, judge that satisfying rated condition from load current begins whether through 45 minutes.If judge timer T8 to the time, then jump to step S166 from step S165, open the 3rd protective emblem FP4, the 3rd protective emblem FP4 is used for identification and whether has satisfied the 3rd condition.In step S167, carry out intermittently and handle, promptly control motor 4, so that electric current is an interrupted current in the mode of break-make.Processing shown in Figure 12 in the time of should intermittently handling with velocity mode is identical.In step S168, judge that whether load current is below the 4th current value 10A less than the 3rd current value.If load current is below the 10A, then jump to step S169 from step S168.In step S169, judging does not need motor 4 is protected, thereby closes the 3rd protective emblem FP4.When the 3rd protective emblem FP4 is closed, then make adjustment return the initial operation position by 101, motor 4 can be moved.

If the judged result among the step S160,161,165,168 is a "No", then returns tension mode and handle.

＜each pattern is handled 〉

In each pattern of step S8 is handled, as shown in figure 16, in step S171, judge whether the direction of rotation of spool 3 is unwinding direction.This judgement is whether any one Hall element according to spool sensor 102 produces pulse earlier and carry out.Be then to jump to step S172 by unwinding direction if judge turning to of spool 3 from step S171.In step S172, spool whenever turns around, and then reads the data of being stored in the storage part 107 according to the revolution of spool, calculates the residing depth of water of fishhook assembly.This depth of water shows by the display process of step S2.In step S173, judge whether the depth of water that calculates consistent with water bottom location, that is, it is water-bed to judge whether the fishhook assembly arrives.This water bottom location is by being arranged in the storage part 107 by store button MB when the fishhook assembly arrives the bottom.In step S174, judge whether to be other patterns such as mode of learning.If not other patterns then finish each pattern and handle, return main program.

If the depth of water is consistent with water bottom location, then jump to step S175 from step S173, make buzzer 106 sounding, so that being arrived water-bed information, the fishhook assembly is notified to the user.In step S174, if there are other patterns, then jump to step S176 from step S174, carry out other patterns of appointment.

Rotate towards the take-up direction if judge spool 3, then jump to step S177 from step S171.In step S177, read the data of being stored in the storage part 107 according to the revolution of spool, calculate the residing depth of water of fishhook assembly.This depth of water shows by the display process of step S2.In step S178, judge whether the depth of water that calculates is consistent with the ship side stop position.If the fishhook assembly is not in the ship side stop position, then return main program.If the fishhook assembly is in the ship side stop position, then jump to S179 from step S178.In step S179, make buzzer 106 sounding, be notified to the user with the information that the fishhook assembly is positioned at the ship side stop position.In step S180, close motor 4.Thus, when having fish to be angled up, fish is to be in the position of easily getting.It is position more than 6m stops the stipulated time with interior and spool 3 that this ship side stop position is set in the depth of water for example.
