BACKGROUND OF THE INVENTION
  The present invention relates to a yarn length measuring device, and more particularly to a fishing reel yarn length measuring device for measuring the length of a fishing line wound on a spool of a fishing reel in a layered manner.
[0002]
[Prior art]
  Fishing reels such as dual-bearing reels and single-bearing reels generally have a reel body, a spool that is rotatably supported by the reel body and for winding fishing line, and a handle that rotates the spool. This type of fishing reel is known which has a line length display mechanism for measuring and displaying the feeding length or winding length of a fishing line from a spool during reel operation (Japanese Patent Laid-Open No. 1-276011). No. JP-A-2-107908). By providing this thread length display mechanism, the mechanism can be accurately lowered to the same shelf position, and the flying distance of the mechanism during throw fishing can be displayed.Can doit can.
[0003]
  This type of yarn length display mechanism includes a yarn length measurement unit that measures the yarn length during reel operation and a yarn length display unit that displays the yarn length measured by the yarn length measurement unit.WhenIt has. The yarn length measuring unit calculates the yarn length from the number of rotations of the spool. Note that the winding diameter of the spool changes according to the number of rotations and the thickness of the yarn, and the yarn length per one rotation of the spool changes depending on the winding diameter. Therefore, in the above prior art, the yarn length calculated from the spool rotation speed is not displayed as it is, but the yarn length is calculated from the spool rotation speed in consideration of the change in the winding diameter due to the difference in the spool rotation speed and the yarn thickness. I am doing so.
[0004]
  Specifically, in the prior art disclosed in the former publication, the yarn length is calculated from the number of rotations of the spool using a calculation formula that takes into account the type of yarn and the winding diameter. In the prior art disclosed in the latter publication, while measuring the line length with a measuring instrument while actually winding the fishing line around the spool, the relationship between the measured value and the spool rotational speed is stored in the memory. The yarn length is calculated from the rotation speed of the spool by reading the relationship between the thread length and the yarn length from the memory.
[0005]
[Problems to be solved by the invention]
  In each of the above conventional configurations, the yarn length is calculated in consideration of changes in the spool diameter and the winding diameter depending on the yarn thickness. Therefore, the error between the actual length and the calculated yarn length is the spool rotation speed. It is slightly smaller than the case where the yarn length is directly calculated from. However, when fish is actually applied to the fishing line and tension is applied to the fishing line, the gap between the fishing lines wound on the spool is reduced, and the winding length per one rotation of the spool is reduced. The spool must be rotated. In other words, when tension is applied to the fishing line, the relationship between the spool rotation speed and the actual yarn length becomes different from the relationship stored in the calculation formula or memory, and the displayed yarn length is actually fed out.WasOr it becomes longer than the wound yarn length.
[0006]
  An object of the present invention is to reduce the length of fishing line reels wound in layers on a spool of fishing reels.,The purpose is to enable measurement with a small error even when tension is applied to the fishing line.
[0007]

Measure the rotation data as the number of bobbin windings, the number of fractions in the top layer and the total number of windings, and the rotation data when the yarn length L is wound with tension applied to the fishing line, and use the rotation data obtained by this measurement. The corrected unit yarn length is calculated by correcting the unit yarn length obtained by the learning means.
[0008]

The measuring instrument main body 54 is attached to the flat section 8 by sandwiching the flat section 8 with the measuring instrument main body 54 and locking the flat section 8 with the projection 59 and then turning the mounting screw 58 to press the depression 9.
[0028]
  The electric reel is connected to a battery (not shown) by a power cord 80 as shown in FIG.
[0029]
  Moreover, the electric reel has the control part 100 shown in FIG. The control unit 100 includes a microcomputer including a RAM, a ROM, a CPU, an I / O interface, and the like, and executes various control operations described later according to a control program. The control unit 100 is connected to various operation keys 6, a spool rotation sensor 101 for detecting the rotation direction and the number of rotations of the spool 12, a relay switch 102, a spool counter 103, and a relay counter 104. Further, the control unit 100 is connected to the alarm 7, the motor drive unit 13a, the display unit 5, the storage unit 105, and other input / output units.
[0030]
  The spool counter 103 is a counter that counts the number of times the spool rotation sensor 101 is turned on and off, and the rotation speed data relating to the spool rotation speed is obtained from the count value SP. The spool counter 103 increases when the spool 12 rotates in the forward direction (rotation in the yarn feeding direction) and decreases when the spool 12 rotates in the reverse direction. The relay counter 104 is a counter that counts the number of times the relay switch 102 is turned on and off._mCan provide data on the actual length of the fishing line.
[0031]
  The storage unit 105 is composed of, for example, a nonvolatile memory such as an EEPROM. As shown in FIG. 6, the internal addresses thereof are a temporary data storage area 110, a learning data storage area 111, a deepest data storage area 112, and shelf position data. It is partitioned into a storage area 113 and another data area.
[0032]
  Next, control processing performed by the control unit 100 will be described with reference to the control flowcharts of FIG.
[0033]
  When the electric reel is connected to the battery via the power cord 80, initialization is performed in step S1. In this initial setting, the count values of the two counters 103 and 104 are reset to “0”, various variables and flags are reset, and the operation mode is set to a preset initial mode.
[0034]
  Next, in step S2, it is determined whether or not various operation keys 6 on the operation panel 4 have been pressed. In step S3, whether or not the spool 12 is rotated is determined by turning on or off the spool rotation sensor 101. In step S4, it is determined whether any other command or input has been made.
[0035]
  If a key is input, the process proceeds from step S2 to step S5 to execute a key input process. If the rotation of the spool 12 is detected, the process proceeds from step S3 to step S6. In step S6, it is determined whether or not the relay switch 102 is turned on. The relay switch 102 is turned on only when the yarn length measuring device 15 is attached to the flat portion 8. The yarn length measuring device 15 is attached when a new fishing line is wound around the spool 12 to learn the relationship between the new spool rotation speed and the yarn length. For this reason, if the spool 12 is rotating and the relay switch 102 is turned on, the process proceeds to step S7 and the learning mode process is executed. When the relay switch 102 is not turned on, the process proceeds from step S6 to step S8 to execute each mode process.
[0036]
  If any other command or input is made, the process proceeds from step S4 to step S9 to execute another process.
[0037]
  In the key input process, as shown in FIG. 8, it is first determined in step S21 whether or not the on / off switch 6a of the drive motor 13 has been pressed. In step S22, it is determined whether or not the shelf position set switch 6b has been pressed. In step S23, it is determined whether or not 0 set has been designated by pressing the set switch 6b for 3 seconds or more. The designation of 0 set is performed when 0 is displayed for the predetermined length of the fishing line. For example, the angler designates 0 set when the fishing line breaks or when the initially designated 0 point is shifted due to the tension acting on the fishing line. In step S24, it is determined whether any other switch has been pressed.
[0038]
  When the on / off switch 6a of the drive motor 13 is pressed, the process proceeds from step S21 to step S25. In step S25, it is determined whether the drive motor 13 is already on. If the drive motor 13 is already on, the process proceeds to step S26, and the drive motor 13 is turned off. If the drive motor 13 is off, the process proceeds from step S25 to step S27, and the drive motor 13 is turned on.
[0039]
  If the shelf position set switch 6b is pressed, the process proceeds from step S22 to step S28. In step S28, the count value C when the set switch 6b is pressed is stored in the shelf position data storage area 113 as the shelf set value T.
[0040]
  If it is determined that 0 set is designated, the process proceeds from step S23 to step S29. In step S29, it is determined whether the count value SP of the spool counter 103 is between 0 point and -200 to +100, that is, 0 set is designated within 100 pulses from the 0 point in the yarn unwinding direction and 200 pulses in the yarn winding direction. to decide. This is a single switch operation that performs a high cut correction that resets the zero point when the fishing line breaks and a tension correction that resets the zero point when the fishing line is tensioned and the zero point is shifted. Because. The two corrections perform different processes in terms of control, but are the same actions for the angler to reset the zero point. Therefore, if such a zero set can be performed by a single switch operation, an extra switch operation is not necessary and the operability can be improved. It is also possible to eliminate this determination and configure tension correction and high-cut correction independently by separate switches.
[0041]
  If 0 set is designated when the count value SP is between 0 and -200 to +100, the process proceeds from step S29 to step S30, and tension correction processing described in detail later is performed. If the count value SP is 0 and the 0 set is specified outside the above range, the process proceeds from step S29 to step S31, and the high cut correction process described in detail later is performed. Here, the reason for determining the difference between the two corrections in the above range is that correction is necessary near the zero point in the case of tension correction, and correction is required away from the zero point in the case of high cut correction. is there.
[0042]
  If any other key is pressed, the process proceeds from step S24 to step S32, and processing corresponding to the pressed key is executed.
[0043]
  When performing the learning mode process of step S8 in FIG. 7, the angler attaches the line length measuring device 15 to the flat portion 8 and winds the fishing line around the spool 12 with the roller 51 in contact with the spool 12. In this learning mode process, the count value LP of the relay counter 104 is determined in step S41 in FIG._mIs set to “1”. In step S42, it waits for the spool 12 to rotate by 200 pulses depending on whether or not the count value SP of the spool counter 103 is divisible by 200. When the spool 12 rotates by 200 pulses, the process proceeds to step S43. In step S43, the count value LP of the relay counter 104 is displayed._mThe count value LP_mIs stored in the temporary data storage area 110 of the storage unit 105. That is, every time the spool 12 rotates by 200 pulses, the count value LP_mIs taken in, and the unit yarn length for every pulse of the count value SP200 is taken in.
[0044]
  In step S44, the relay counter 104 is cleared to detect the yarn length during the next 200 pulses. In step S45, the variable m is incremented by 1, and the process proceeds to step S46. In step S46, for example, it is determined whether or not the fishing line spool has been wound based on whether or not the set switch 6b is operated. If the winding has not been completed, the process returns to step S42 and waits for the next 200-pulse spool 12 to rotate.
[0045]
  When it is determined that the fishing line has been wound around the spool 12, the process proceeds to step S47, and the maximum value of the variable m is set to the variable M. In step S48, the variable m is set to “1”. In step S49, the count value LPm stored in the temporary data storage area 110 is read. In step S50, the read count value LP_mAnd two count values LP read before that_m-1, LP_m-2Is added to calculate the moving average of the three count values, and this is calculated as unit yarn length data A_mAnd stored in the learning data storage area 111 of the storage unit 105 in association with the variable m. The first two count values LP₁, LP₂And the last two counts LP_M-1, LP_MWhen moving average is used, the average value of one or two count values is used as unit yarn length data. Here, since moving average processing is performed, highly reliable data can be obtained even if noise or omission occurs in the count value.
[0046]
  In step S51, the variable m is incremented by 1, and the process proceeds to step S52. In step S52, all count values LP_mIt is determined whether or not the averaging process is completed. If the averaging process is not completed, the process returns to step S49 and the next count value LP_mIs read. When the averaging process is completed, the process proceeds to step S53, and a linear regression process is executed. Unit yarn length data A obtained by averaging_mIs the yarn length data every time the spool 12 rotates 200 pulses as described above, and this data is data whose value increases as the fishing line is wound around the spool 12, that is, in proportion to the number of revolutions of the spool. . Therefore, in step S53, the unit yarn length data A_mAnd the relationship between the variable m and the linear line.
[0047]
  The linear regression process in step S53 is performed in step S61 of FIG. 10 in the first four unit yarn length data A at the start of winding.₁~ A_FourAre read from the learning data storage area 111. In step S62, four data A₁~ A_FourTo the first regression line L indicated by a dotted line in FIG.₁Is calculated. Here, since the thick fishing line is used as the lower fishing line, the inclination a₁Is a large value. Where the intercept is b₁Then, the first regression line L₁Is A_m= A₁m + b₁It becomes.
[0048]
  In step S63, the last four unit yarn length data A at the end of winding_M-3~ A_MAre read from the learning data storage area 111. In step S64, four data A_M-3~ A_MTo the second regression line L indicated by a two-dot chain line in FIG.₂Is calculated. Here, since the fishing line thinner than the bottom fishing line is used, the inclination a₂Is the first regression line L₁The value is smaller. Where the intercept is b₂Then, the second regression line L₂Is A_m= A₂m + b₂It becomes.
[0049]
  In step S65, two regression lines L₁, L₂Intersection of (m_c, A_mc) In step S66, it is determined whether or not there is an intersection. Here, two regression lines L₁, L₂The intersection of is negative (m_c<0) or larger than the final data M (m_cIf> M), it is determined that there is no intersection. If it is determined that there is an intersection, the process proceeds from step S66 to step S67, and data after the intersection (m> m_c) Only, and the third regression line L indicated by a one-dot chain line in FIG._ThreeIs calculated. This slope is a_Three, Intercept the b_ThreeThen the third regression line L_ThreeIs A_m= A_Threem + b_ThreeIt becomes. In step S68, the obtained third regression line L_ThreeThread length data A related by₁~ A_MAre all calculated. If it is determined that there is no intersection, the process proceeds from step S66 to step S69. In step S69, the obtained second regression line L₂Thread length data A related by₁~ A_MAre all calculated.
[0050]
  In step S70, the obtained second regression line L₂Or the third regression line L_ThreeBased on the above, the unit yarn length data A of the area above the data learning area (upper winding area) and the lower area (lower winding area)_{M + 1}~ A_{M + 16}And unit yarn length data A₀~ A_-FourIs calculated. This is to prevent the line length display from disappearing when the fishing line is cut or when a tension is applied to the fishing line. In step S71, the obtained unit yarn length data A_-Four~ A_{M + 16}And the variable m are overwritten in the learning data storage area 111. In this manner, the relationship between the spool length and the yarn length that changes depending on the spool diameter and the yarn diameter is learned. As a result, for example, unit yarn length data A as shown by a solid line in FIG._mAnd the variable m are stored in the learning data storage area 111. Here, the length of the fishing line is indicated by the area under the straight line. That is, since the count value SP of the spool counter 103 is 200 times the variable m, the count value C of the yarn length can be calculated by calculating the area from the 0 point to the count value SP.
[0051]
  In each mode process, it is determined in step S81 in FIG. 11 whether or not the rotation of the spool 12 is in the feeding direction. This determination is made based on the output from the spool rotation sensor 101. In the case of the feeding direction, the process proceeds to step S82, and the count value SP is incremented by 1, for example. In step S83, the unit yarn length data A from the learning data storage area 111 of the storage unit 105 based on the count value SP._m, And the read unit thread length data A_mThe count value C is obtained from the above and displayed on the display unit 5. In step S84, the calculated count value C is the deepest value C._maxJudge whether it is larger. Count value C is deepest value C_maxWhen it is larger, the process proceeds to step S85, and the calculated count value C is changed to the deepest value C._maxAnd stored in the deepest data storage area 112 of the storage unit 105. In step S86, it is determined whether or not the automatic shelf stop mode is set. This determination is made, for example, based on whether or not the shelf set value T is set. In step S87, it is determined whether another mode such as an automatic pitching mode is set.
[0052]
  When the automatic shelf stop mode is set, the process proceeds from step S86 to step S88, and the automatic shelf stop process is executed. If another mode process is set, the process proceeds to step S89 to execute another mode process.
[0053]
  When the rotation of the spool 12 is in the winding direction, the process proceeds from step S81 to step S90. In step S90, the count value SP is decremented by one, for example. In step S91, the unit yarn length data A from the learning data storage area 111 based on the count value SP._m, And the read unit thread length data A_mThe count value C is obtained from the above and displayed on the display unit 5. In step S92, the boat alarm water depth C_FAAnd the count value C are determined. Shipboard alarm depth C_FAIf the count value C is equal to the count value C, the process proceeds to step S93, and a shipboard alarm process is executed. Shipboard alarm depth C_FAIf the count value C does not match the count value C, the process proceeds from step S92 to step S94, and it is determined whether the count value C is equal to or less than a predetermined value. When it is below the predetermined value, the process proceeds to step S95, and the drive motor 13 is turned off.
[0054]
  In the tension correction process of step S30 in the key input process of FIG. 8, the count value SP is set to 0 in step S101 of FIG. In step S102, the deepest data C is stored in the deepest data storage area 112._maxIs stored, and the deepest data C_maxIs stored, the process proceeds to step S103. In step S103, as shown in FIG._maxUnit yarn length data A after the variable m corresponding to the count value SP corresponding to_mFrom the following equation (1), corrected unit yarn length data A ′_mAsk for.
[0055]
[Expression 1]

  Here, in order to simplify the explanation, it is assumed that the variable m (for example, the number of spool layers of the spool 12) increases every n rotations (for example, every 200 rotations), and as shown in FIG.₁~ A_mM addresses to the layer and a_{m + 1}It is assumed that the data in the learning data storage area 111 in the storage unit 105 is configured by rotating the fraction p of the layer. Here, unit yarn length data A_mIs
  A_m= NπD_am= NπD_a0+ 2mnπd₀
It can be expressed as
[0056]
  Further, the tension acts on the fishing line and the fishing line is flattened so that the fishing line diameter d '₀Is the original diameter d₀When it becomes smaller, the number of layers increases by x layers as shown in FIG.₁~ A_{(m + x)}M + x addresses to the layer and a_{(m + x + 1)}It is assumed that the data in the learning data storage area 111 in the storage unit 105 is configured by a fractional q rotation of the layer. Here, the corrected unit yarn length data A ′_mIs
  A ’_m= NπD ′_am= Nπ (D_a0+ D₀+ (2m-1) d '₀)
It can be expressed as
[0057]
  Based on these relationships and the fact that the yarn length L does not change before and after the action of tension, the above equation (1) is obtained.
[0058]
  In step S102, the deepest value C_maxIf it is determined that there is not, the process proceeds to step S104, and high cut correction processing is performed. This means that the yarn has never been unwound and wound up so far.
[0059]
  In step S105, the obtained corrected unit yarn length data A ′._mIs stored in the learning data storage area 111, the correction by the tension is completed, and the process returns to the input key process. In the high cut correction process in step S31, the unit yarn length data of the variable m corresponding to the count value SP at the time point when 0 set is pressed in step S111 in FIG. In step S112, the count value SP is set to 0, and the process returns to the input key process. As a result, high cut correction is performed.
