(Patent Document 1): Japanese Patent Laid-Open No. 3-1 9 8 7 3 3. [Summary of the Invention] Generally speaking, the electric reel is a large change in the load of the fish caught, so the thermal countermeasures to prevent burning of the motor or control components are very important, especially for small electric reels. In the device, the current passing through the motor is very large compared with the size of the motor, and it is easy to generate heat due to the change of the load. Therefore, the thermal countermeasure system is very important. According to the results of various experiments of the present invention, it is obtained that under the condition that the tension on the fishing line and the rotation speed of the reel are constant, if the frequency of the driving pulse signal is increased, the heat generation of the motor can be reduced. (fact). However, components such as FETs or capacitors used in motor drive means that the frequency of driving pulse signals becomes higher and the frequency of 0N · 0FF of electric power becomes higher. The subject of the present invention is to try to suppress the heat generation of the motor in the motor control device of the electric reel. Another problem of the present invention is that in the motor control device of the electric reel, on the one hand, it suppresses the heat generation of the motor, and on the other hand, it makes the electrical components less prone to undesirable situations.

The frequency FQ of the driving pulse signal DS is 1 0 Above kHz, it is better to be above 15 k Η z, and less than 20 k Η z is appropriate. If the frequency FQ of the drive pulse signal DS is less than 15 k Η ζ, the change in the calorific value will not be noticeable. When it is more than 20 k Η ζ, the heat generation of the field effect transistor 60 and 61 will increase. At the same time, the capacitor 62 may be damaged when an electrolytic capacitor is used. The memory section 46 is, for example, EEPR 0M, etc. The non-volatile memory is composed of 0 in the memory section 46: as shown in FIG. 5, a display data memory area 50, which is used for display data of the storage shed position, etc., and the memory indicates the actual line length and reel The relationship between the number of rotations, the learning data, the memory area 5 1, and the upper limit of the reel speed (rpm) of the roll 10, which memorizes the number of segments SC in response to the speed, the speed data memory area 52, and the memory every 5 The tension of the stage is, for example, response to the load of the coil diameter of the motor of stage 10, the load tension of the data memory field 5 3, and the memory of all kinds of data. The field of record is 54 °, which is in the field of speed memory 5 2. ： Number of segments SC is 1 SS = 2 5 7 r · p · m. 2 times SS 2 3 6 9 r · p · m -13-(11) (11) 200414873 ， 3 times SS = 5 0 3 r. P. M ， 4 Continuous SS = 6 6 5 ι ·. P. M, 5 Continuous SS = 1 0 0 0 r · p · mo is contained in the area of tension data memory 5 3, which responds to the reel diameter and the maximum wire reel diameter The number of tensions between them corresponds to the number of the load ratios of the coil diameter in the plural stages (data). For example, when the number of tension stages is TC, the load ratio (%) is TS = 17 ~ 25, TS = 27 ~ 40 in 2 stages, Ts 2 in 40 ~ 60 in 3 stages, and TS 2 in 53 ~ 80 in 4 stages. At the time TS = 67 ~ 100, the vehicle place is memorized separately, the number of stage 0 from the reel diameter to the maximum wire reel diameter. The load ratio of these is the load ratio of the diameter of the reel to the maximum diameter of the coil immediately before the stop when the tension of 5 stages is applied to the reel 10, for example, based on the measurement results obtained. The decider. Specifically, it contains: the relationship between the load ratio and the wire diameter is approximated once by the number of two load ratios of the diameter of the drum and the maximum wire diameter when the tension in the same stage is applied. Straight line, the load ratio when calculating a plurality of wire winding diameters by a straight line obtained by approximating it, and responding to the load ratio of the wire winding diameter at each stage obtained. In the data memory field 54, various temporal data such as the set number of speed segments SC or the number of tension segments TC are stored. The outline of the method for calculating the line length in this embodiment will be described below. In the present invention, the relationship between the length Y of each reel of the reel and the number X of reels of the reel can be approximated to a straight line to calculate the line length. Take the fishing line of unknown thickness and full length, assuming the winding diameter is Bmm, and start winding on the reel] 〇, rotate all the fishing line with C, then, from -14-(12) (12) 200414873 In this state, when the fishing line S mm was sent out, the 'reel] was rotated ^ rotated. Now, the relationship between the number of reel rotations X and the line length Y of each reel rotation is shown on the horizontal axis, and the vertical axis represents the equivalent line length for each reel rotation. Since it must be defined by a straight line, the slope is set to A, which can be expressed by the following formula. Y = AX + B 71 ...... (1) Therefore, the graph showing the relationship between the number of reel rotations X and the line length Y at each reel rotation is as shown in FIG. 6. Suppose that the length of each reel of the reel when the reel 1 oc rotates is γ (c). After C is wound, the specified length S will be sent out. When the line length is Y (C — d), these can be expressed as shown below. γ (c) Two A.C + Btt ...... (2) Y (c— d) = Α · (c-d) + B π ...... (3) lies in Figure 6 In the graph shown, the area indicated by the shading is equivalent to the wire sending length S after the winding is completed, so the wire sending length s can be expressed as follows. S = d {Y (c) + Y (cd)} / 2 ...... (4) Substituting (4) for (2) and (3), it becomes s. D · {A · C + Β τι + A · (cd) + B π} / 2 two d · {A · (2c— d) + 2 B} / 2 ...... (5) With respect to (5) the solution A becomes as follows. A 2 2 (S-Β 7Γ d) / d (2 c — d) ...... (6) So we can find 4 numbers 値 S 'B' c 'd and substitute it into the formula (6). -15-(13) (13) 200414873 straight slope A. For example, the reel 10 is rolled from the beginning and revolved at 2000. When the reel 10 is sent from there, the reel rotates 60 revolutions. The diameter of the reel 10 (wire diameter) is At 30 mm, the slope a of a straight line is as follows: A = 2 (10000-94.2 * 60) / 60 (2 * 2000-60) = 0.0368 and if it can be determined, the slope A, the approximate straight line of slice B ττ When a straight line is applied to the integral processing (area calculation processing) of each rotation of each reel, the length of each rotation of the reel can be obtained from the switch winding to the completion of the winding, for example, the line length L]. After setting the water depth LX at the time of the reel rotation number C when the winding is completed, the relationship between the water depth LX (two LN) and the reel rotation number X from that point to the start of the winding is calculated, and it is in the memory section. 4 6 of the learning and memory field 51, for example, in the form of a map (LX di MAP (X)) and memorize. During actual fishing, such as when the reel 10 rotates, according to the number of reel rotations X detected by the reel sensor 41, and the line length LX is read from the map of the memory section 46, according to the read out The line length LX lies in the water depth (water depth at the tip of the fishing line) of the display mechanism 5 on the display section. The specific control processing performed by the reel control section 30 will be described below with reference to the control flowchart shown in FIG. 7. When the electric reel is connected to an external power supply via a power cord, the initial setting of step S1 in Figure 7 is performed. At this initial setting, the count of the roll counter 42 is reset, or various variables or marks are implemented. Reset and change the motor control mode to speed control mode, and the display mode is changed to the mode from the top. -16-(14) (14) 200414873 Next, display processing is performed in step s2. In the display process, various display processes such as water depth display are implemented. In this case, if the speed mode is used, the number of speed segments operated by the lever 3 2 is not displayed in the status display area 5 C of the h-degree segment display area. In the tension mode, the tension lx number is displayed in the tension segment display area. One of the control modes of the speed mode and the tension mode is also displayed. ○ In step S3, it is judged whether the switch or motor of one of the operation key portions 6 is turned off 31 or the state change lever 32 is operated. At step S4, it is determined whether the reel 10 is rotating or not. This determination is made by the output of the reel sensor 41. In step S5, it is determined whether there are other instructions or inputs. If the switch has been connected, go from step S3 to step S6 to implement the construction input ^. When the rotation of the reel 10 is detected, the process moves from step S4 to step S7, and each operation mode processing is performed in step S7. When there are other instructions or inputs, the process moves from step S5 to step S8 to implement other processing. The key input processing of step S 6 lies in step s in FIG. 8! % _ OFF mode switch MD is pressed. In step S1 3, it is determined whether the state change lever 32 is operated on the increase side. It is determined in step S 1 4 whether the state change lever 32 is operated on the decreasing side. It is determined at step S 1 5 whether other switches are operated. Other switch operations include various operations in the menu mode. If the mode switch MD is pressed, it moves from step S 1 1 to step s}} 〇 In step 〖7, it is judged whether the motor control mode is the speed mode. In the -17- (15) (15) 200414873 speed mode, the mode switch MD is pressed to indicate that the angler wants to change to the tension mode green, so go to step 19 and set the control mode to the tension mode. Therefore, torque control is performed in response to the operation of the change switch S K. If it is not the speed mode but the tension mode, go from step s 1 7 to step S 1.8 to set the motor control mode to speed mode. When the motor switch 31 is pressed, the process proceeds from step S 1 2 to step S 2 0. At step S20, it is judged whether the motor 12 has been turned on (in rotation). When the motor switch 3 1 is pressed during the rotation of the motor, it indicates that the angler wants to stop the rotation of the motor 12, so the process goes to step S22 and the motor 12 is turned off. When the motor is stopped, the process moves from step S20 to step S21 to make Motor 12 is ON. When the operation of the state change lever 3 2 is on the acceleration side, the operation moves from step S 1 3 to step S 2 3. In step S 2 3, it is determined whether the control mode is a speed mode. In the speed mode, the process proceeds to step S 2 5. The speed increase processing described later is performed. In the tension mode, the process proceeds from step S23 to step S24, and a tension increasing process described later is performed. In this example, if the state change lever 32 is operated on the increase side, speed increase processing or tension increase processing is performed, so as a result, only the increase time is performed by operating the increase side time. When the state change lever 3 2 is operated on the decreasing side, the process proceeds from step S 4 to step S 2 6. It lies in step S 2 6 to determine whether the control mode is the speed mode. In the speed mode, the process proceeds to step S 2 8 'to perform speed reduction processing described later. In the tension mode, the process proceeds from step S26 to step S27. Perform the tension reduction process described later. In this example, the state change lever 3 2 is operated when it is operated on the reduction side. -18- (16) (16) 200414873 The speed reduction or tension reduction process is implemented, so as a result, these are implemented only when the operation is performed on the reduction side. Reduce handling. When other switch inputs are implemented, the process moves from step S 1 5 to step S 2 9. For example, in response to the other key input processing that is performed by the switch input of the operation performed at the current depth of the shed. The speed increase processing step in step S 2 5 is that in step S 5 1 in FIG. 8, the previously set speed segment number s C is read from the data memory area 54. In this example. This frame is memorized every time the number of speed segments SC increases or decreases. When the power is turned on again, or when the motor switch 31 is pressed and the motor 12 is stopped, the number of speed stages SC is set to "0", and it is stored in the data memory area 54 °. The speed to be read in step S 5 2 The number of segments SC is increased by one segment. The increased number of speed segments S C at this time is displayed in the speed segment number display area 5 C during display processing, and is stored in the data memory area 5 4 at the same time. After the motor switch 3 1 is pressed straight, the number of speed stages S C is raised by one and set to "1". The speed segment number S C is set to "5", which means that it will not increase. In step S53, the speed data memory field 52 is read out to set the speed data SS in response to increasing the number of segments SC. In step S 5 4, the speed data of the reel 10 is read from the output of the roll sensor 41 1. At step S 5 3, the speed data memory area 5 2 is read and the response is in response to the increased number of speed segments SC. The speed data SS is set. At step s 5 4 the speed data SP of the reel 10 is read by the output of the roll sensor 4] At step S55, it is determined whether the read speed data SP becomes a response to • 19- (17) (17 ) 200414873 The number of speed segments s C and the speed data s S or more, if the speed data s P is less than the speed data S s, go from step S 5 to step s 5 6. At step S56, the current load ratio 0 is read from the data memory field 54. In the data memory field 54, the load ratio D is set each time, and the set load ratio D is memorized. In step S 5 7, it is determined whether the current load ratio read from the data memory field 5 4 is above the maximum load ratio. This maximum load ratio Du is usually “1 0 0”, but it depends on the number of speed stages. SC or the load of the motor 2 and so on to change the setting of the maximum load ratio. When the load ratio D is less than the maximum load ratio D u, the process moves from step S 5 7 to step S 5 8 and the load ratio D is increased by a predetermined increment D I and set. The drive pulse signal D S in response to the set load ratio is output to the PWM drive motor 45. The newly set load ratio D is memorized in the data memory field 54 〇 Furthermore, the increase D I is for example "5". When the judgment of the load ratio D in step S 5 is greater than or equal to the maximum load ratio Du, the process proceeds to step S 5 9. In step S 5 9, the load ratio D is set to the maximum load ratio Du, and in response to step S5 8 or The driving pulse signal DS of the load ratio set at S 59 is output to the PWM driving motor 45. On the other hand, when the speed data SP is judged to be above the speed data S S in step S 55, the process returns to the key input process without any processing. After completion of the processing of step S 5 8 or S 5 9, the process returns to the key input processing. In this speed increasing process, only the operating state changing lever is used to increase the number of speed segments SC at the time of the increasing side, so that the speed of the reel] 0 is increased to -20- (18) (18) 200414873 in response to the increased speed Number of segments SC scroll speed. When the operation of the state change lever 32 is stopped again, the speed increase process or the speed decrease process will not be performed until the state change lever 32 is operated again, so the number of speed stages SC resulting from the speed increase is maintained and the roll is maintained. speed. The tension increasing process in step S24 is not implemented: as in the speed mode, the speed is detected as a closed loop (c) 〇se 1 ο ο p) control to change the load ratio at that speed, but it is set every ~ In the tension stage, the load ratio TS is set with the winding diameter SD per wire, and the open loop (0 P e η 1 ο ο p) is controlled by the load ratio TS. In the tension increasing process, in step S 61 in FIG. 10, the data is read from the data memory area 54 and the previously set tension segment number TC. In this example, in the field of data memory 54, the frame is memorized with an increase or decrease in the number of tension sections T C at a time. When the power is turned on and when the motor switch P W is pressed and the motor 12 is stopped, the number of tension segments TC is set to "0" and stored in the data storage area 54. At step S 62, one of the read tension number τ C is raised. The increased number of tension segments T C at this time is displayed in the tension segment number display area 5 e during display processing, and is also stored in the data memory area 5 4. After the motor switch 3 1 is pressed straight, the number of tension sections τ C is raised by one and set to "1", and the number of tension sections T C is set to "5" and will not increase. In step S 6 3, a calculation process of the wire winding diameter s d is performed. In the process of calculating the winding diameter, it reads the reel rotation number X at step S 7 in FIG. 11. In step S 7 2 'based on the number of reel rotations x, calculated from a one-time formula -21-(19) (19) 200414873, which represents the relationship between the length of the reel rotation γ obtained by the learning process and the reel rotation. The length Y of the reel. In step s 7 3, divide the length γ obtained by rotating the obtained reel once by π to calculate the thread winding diameter s D ° At step S 64, read out the tension coil memory diameter 5 3 in response to the calculated coil winding diameter. SD and the load ratio TS 'of the increased number of tension segments TC are set. And the driving pulse signal D S in response to the set load ratio T S is output to the P W M driving motor 45. As a result, the load ratio T S is set to be corrected by the thread winding diameter SD, and the tension applied to the fishing line is often similar to the set tension. In this tension increasing process, only the time when the state changing lever 32 is operated on the increasing side and the number of tension segments Tc is increased, and the load ratio in response to the tension of the increased number of tension segments TC can be read in response to the winding diameter T s is set. When the operation of the state change lever 32 is stopped again, the tension increase process or the tension decrease process will not be performed until the state change lever 32 is operated. Therefore, the number of tension stages TC of the tension increase result is maintained. Maintain its tension. As a result, when the load becomes larger, the speed becomes slower, and when the load becomes smaller, the speed becomes faster. Therefore, when the mechanism with a small load (Shihang) is recovered, the mechanism can be recovered at a high speed (Shihang), and then it will be faster to place it again. In addition, the load ratio TS ′ is set in response to the thread winding diameter, so the tension applied to the fishing line becomes constant. Therefore, it is not easy to break the fish mouth when it is rolled up, and it is not necessary to adjust the drag resistance at the same time. The speed reduction processing in step S 2 8 is based on step S 8 1 in FIG. 12, which is read from the data memory area 54 and the previously set speed segment number S C. The step S 8 2 is to reduce the number of speed segments s C read out by one step. The reduced number of speed segments S C at this time is displayed in the speed segment digital display -22- (20) (20) 200414873 in the display process 5c, and is also stored in the data storage field 54. When the number of speed stages SC is reduced to "1", it will not decrease any more. In step S 8 3, the speed data S S in response to the number of speed segments S C reduced by the speed data memory area 5 2 is read. In step S84, the speed data SP of the reel 10 is read out from the output of the reel sensor 41. It is determined in step S 8 5 whether or not the read speed data SP is the speed data S S or less in response to the set number of speed segments S C. If the speed data SP exceeds the speed data S S, the process moves from step s 8 5 to step S 8 6.

It is judged in step 87 whether the current load ratio D read from the information memory field 54 is the minimum load ratio D l the above. This minimum load ratio D l is usually "". When the load ratio D exceeds the minimum load ratio D1, the process proceeds from step S57 to step S88. The load ratio D is reduced by a predetermined fraction DI. The load ratio D of this setting is memorized in the field of data recording. The decrement DI is, for example, "5", and when the load ratio D is determined to be less than the minimum load ratio D L in step S 8 8, the process proceeds to step S 89. In step S89, the load ratio D is set to the minimum load ratio D1. And in response to the load ratio set in step S88 or step S89, the driving pulse signal DS is output to the PWM driving motor 45. On the other hand, in step S85, it is judged that the read speed data SP is equal to or less than the speed data S S that is responsive to the set number of speed segments S C. That is, return to key input without any processing. The processing of step S 8 or S 8 9 is completed again. -23- (21) (21) 200414873 Return to the key input processing. The deceleration process is also performed here. Only the time when the state change lever 32 is operated to the deceleration side is reduced by the number of speed steps S C, and the reel speed of the reel 10 is reduced to the rewind speed in response to the decreased number of speed steps S C. In addition, when the operation of the state change lever 32 is stopped, the speed increase process or the speed decrease process will not be performed until the state change lever 32 is operated again. Therefore, the number of speed stages SC as a result of the speed decrease is maintained. Speed is maintained. The tension reduction processing in step S 2 7 is that in step S 9 1 in FIG. 13, the number of tension segments TC that have been set before being read out from the data memory area 54. In this example, in the field of data memory 54, when the number of tension segments TC increases or decreases each time the system is memorized. When the power is turned on and the motor switch PW is pressed and the motor is stopped, the number of tension segments TC is set to "0" and stored in the data memory field 5 4. In step S92, the number of tension segments read is reduced by one. The reduced number of tension segments T C at this time is displayed in the tension segment number display field 5 e during display processing, and is stored in the data memory field 5 4 at the same time. After the motor switch PW is pressed, the number of tension steps is increased by one step and set to "1". The number of tension steps TC is set to "1", that is, the number of tension steps TC will not be reduced below this threshold. In step S93, calculation processing of the wire winding diameter SD is performed. The calculation process of the thread winding diameter shown in FIG. 11 is the same as the tension increasing process, so the description is omitted. At step S94, it is read out from the tension data memory area 53. In response to the calculated thread winding diameter SD and the decrease, The load ratio of the number of tension sections TC is TS. And for the PWM drive motor 45, the output is in response to the set load ratio TS -24-(22) 200414873 dynamic pulse signal D s. As a result, the load ratio T S to be set becomes the one corrected by the thread winding diameter S D, so the tension acting on the fishing line can often be close to the set tension. In this tension reduction process, the tension number TC is reduced only when the state changing lever 3 2 is operated on the reduction side, and the tension can be read in response to the reduced tension number TC in response to the thread winding diameter. The load ratio is set to TS.

Therefore, the number of tension segments TC resulting from the tension reduction is maintained and maintained. Its tension. As a result, when the load becomes larger, the speed becomes slower, and when the load becomes smaller, the speed becomes faster. Therefore, when the mechanism (Shihang) with a small load is recovered, the mechanism (Shihang) can be recovered at high speed. Re-loading will become faster, and the load ratio TS will be set in response to the thread winding diameter, so the tension system acting on the fishing line can become constant, so that it is not easy to break or break the fish mouth when it is rolled up, and No adjustment of drag resistance is necessary. In each of the operation modes of step S7, in step s of the fourth figure, it is judged whether the rotation direction of the reel 10 is the direction of sending out the line. This judgment is made by the reel sensor 41. One of the reed switches first sends out a pulse to judge. When the rotation direction of the reel 10 is judged to be the direction of the feed line, the process moves from step S 1 01 to step S 2 02. In step S 102, the water depth is calculated from the data memorized in the memory 1 and 4 6 with the decrease of the number of rotations of each reel. This water depth is displayed in the display processing of step s2. -25- (23) (23) 200414873 In step S 103, it is judged whether the obtained water depth is in accordance with the bottom position—in other words, it is judged whether the mechanism (Shi Hang) has reached the bottom. Bottom position _% When the mechanism reaches the bottom, press the memory switch TB to set it to% memory 4 6. In step S 1 (M, it is judged whether it belongs to other modes. When it does not belong to other modes, complete the processing of each action mode and return to the main program. When the water depth is consistent with the bottom position, move from step S 103 to 歩_ S 1 0 5, beeping, the buzzer 4 4 used by the mechanism has reached the bottom position. Other; in the ^ mode, it moves from step S 1 4 to step S 1 06 and implements the other specified mode. When the rotation of the reel 10 is judged as the upper direction of the thread reel, it proceeds from step S 1 〇i @ to step S 1 0 7. In step 10 7 the number of reels is read and stored in the memory section 4 6 The water depth is calculated based on the data (data). This water depth is processed and displayed according to the display of step s 2. At step S 108, it is determined whether the water depth is consistent with the rim stop position. At this time, it will return to the main program. When it reaches the rim stop position, it will move from step S 108 to step S 109. At step S 109, it will beep in order to inform the fact that the agency is on the rim. Buzzer 44. In step S1 10, the motor 12 is turned off, so that when the fish is hooked, the fish is easily placed in The position of the boat edge is, for example, within 6 meters of water depth, and the reel is set to stop for more than 10 minutes. This electric winder is used when the tension mode is selected by the mode switch MD. The number of segments will each control the tension to a certain degree. Therefore, -26-(24) (24) 200414873 is that it is not easy to break or break the fish mouth when it is rolled up, and it uses a split ring (〇pen 1 ο 〇 p) control to control the tension to a certain level, so the load ratio will not change up and down during the control, but the load ratio will slowly increase in response to the thread diameter, so that the reel can be suppressed when the tension is controlled. The fluctuation of the rotation speed can suppress the movement of the head and suppress the increase of power consumption, and it is not necessary to detect the current tension with torque or the like, so that the structure of the control system can be simplified. Also, because the driving pulse signal DS The frequency FQ is a high frequency above 10kHz, so it can suppress the heat generation of the electric motor. [Other Embodiments] (a) The above embodiment is based on the increase in position of the state change lever and An example is to reduce the swing of the position to set the rotation state of the motor. However, it is also possible to set the rotation state of the motor by the swing amount of the state change lever. At this time, the rotation state starting from the stopped state of the motor can also be set. Or instead of the state changing lever, it can be constructed by setting the number of steps of speed or torque to increase or decrease the number of operations or operating time of a separate switch, etc. c (b) The above embodiment is constructed so that the speed can be selected by speed Control and tension control by torque, but it is also possible to implement one of them. Effect of the invention] According to the present invention, the frequency of the driving pulse signal is higher than 10 kHz -27- (25) (25) 200414873 Frequency, which can suppress the heat generation of electric motors.
