光路徑L21及光路徑L22。 此時，個別光路徑是第一 LED部310及第二LED部320所發射光線 被第一光接收部210及第二光接收部220接收所沿著的光路徑。因此，較 佳的疋不限制第一 LED部310所發射的光線是在光路徑L11及光路經l12 之間的某-範_。例如’第-導光部311的大小或形狀會被設定成使得 光線是在比光路徑L11及光路徑L12之間所定義還寬的某一範圍内輻射。 而且’較佳的疋不限制第一 LED部320所發射的光線是在光路徑[21 及光路徑L22之間的某-範圍内。例如，第二導絲切的大小或形狀會 被設定成使得光線是在比光路徑L21及光路徑L22之間所定義還寬的某一 範圍内輕射。 ' 參閱第4圖，將詳細說明依據本發明另一實施例的感測裝置。 在第4圖所示的感測裝置中，第一感測器單元2 〇〇是配置成使得第一 光接收部210及第二光接收部220是安置在第一感測器盒2〇1中。 如第4圖所示，第一光接收部210及第二光接收部22〇可曝露至外 201105390 部’使得第- LED部310及第二LED部32〇所發射的光線可直接被第一 光接收部210及第二光接收部22〇接收。另—方式是，第—光接收部21〇 及第二光接收部220可安置在第一感測器盒2〇1 t，且多個貫穿孔可在第 一感測器盒2〇1内形成’使得第一 LED部31〇及第二咖部32〇所發射 的光線能經該等貫穿孔而被第一光接收部2!〇 &第二光接收部22〇接收。 另方面，第一感測器單元300較佳地係配置成使得安置第一 led 部310及第二LED部32㈣平板33〇是安置在第二感測器盒3〇ι中。 而且，第二感測器盒301較佳的係設置第一導光部3na以及第二導 光邛311b，第一導光部311a係用以引導從第一 led部310發射的寬廣光 線而使得光線能輻射至第一光接收部210，而第二導光部31比係用以引導 從第-LED部31G發射的光線而使得光線能輻射至第二光接收部22〇。第 導光部311a以及第二導光部311b是位於對應至第二感測器盒3〇1的第 一 LED部310之位置。 ♦此外，第二感測器盒301較佳地係設置第三導光部322a以及第四導 光部322b，第二導光部322a係用以引導從第二LED部320發射的寬廣光 線，而使得光線能輻射至第一光接收部210,而第四導光部32213係用以引 導從第二LED部320發射的光線，而使得光線能輻射至第二光接收部 220。第二導光部322a以及第四導光部322b是位於對應至第二感測器盒 301的第二LED部320之位置。 第一導光部311a限制光線發射的範圍以使得第一 LED部31〇發射的 光線被引導至第一光接收部210 ’而第二導光部311b限制光線發射的範圍 以使得第一 LED部310發射的光線被引導至第二光接收部22〇。 而且，第三導光部322a限制光線發射的範圍以使得第二led部320 發射的光線被引導至第一光接收部210，而第四導光部322b限制光線發射 的範圍以使得第二LED部320發射的光線被引導至第二光接收部220。 第一 LED部310發射的光線被傳送至第一光接收部21〇,而該光線是 被第一導光部3lla引導以形成光路徑L11。而且，第一 led部310發射 的光線被傳送至第二光接收部220，而該光線是被第二導光部311b引導以 形成光路徑L12。另一方面，第二LED部320發射的光線被傳送至第一光 接收部210，而該光線是被第三導光部322a引導以形成光路徑L21。而且， 201105390 第二LED部320發射的光線被傳送至第二光接收部220，而該光線是被第 四導光部322b引導以形成光路徑L22。 此時，較佳的是不很制光線穿過個別導光部311a、311b、322a及322b 是在很小的範圍内。例如，個別導光部311a、311b、322a及322b的大小 及形狀可設定成使得光線能經由個別的貫穿孔211及222而充分的傳送至 個別光接收部2 ί〇及220。 此後，將參考第5圖以詳細說明依據本發明實施例之感測裝置的控制 系統。 如第5圖所示’第一 LED部310及第二LED部320是連接至調 節器R’且第一光接收部210及第二光接收部220是連接至控制器Μ» 調節器R可以預設時間間隔交替閃爍第一 LED部310及第二LED部 320 °當高爾夫球被個別的第一光接收部21〇及第二光接收部22〇感測以 計算高爾夫球的移動方向或移動速度時，控制器Μ可量測時間數值，並將 詳述於後。 雖然，第一 LED部310及第二LED部320是連接至調節器R,且第 一光接收部210及第二光接收部220是連接至控制器μ，如第5圖所示， 但是第一 LED部310、第二led部320、第一光接收部210及第二光接 收部220可由單一控制單元控制。 〇亦即，如第5圖所示，調節器R及控制器Μ可個別設置，使得調節 器R及控制器Μ執行獨立功能。另一方式是，調節器R及控制器Μ可整 合成單一控制單元。 第6圖及第7圖為顯示藉依據本發明實施例之感測裝置以感測高爾夫 球移動之原理的示意圖。 如第6圖及第7圖所示，第一 LED部310及第二LED部320是以非 常短的時間間隔(數跡至數十微秒(10-6秒))交替閃燦，誠高爾夫球可穿 過光，Lll、L12、L21及L22並被偵測到而沒有任何困難。 當高爾夫使用者對高爾夫球進行推桿時，高爾夫球很緩慢移動。例 =高爾夫球具有1〇m/s或更小的速度。高爾夫球可較快移動，然而高爾 夭球的速度不會超過上述數值。 亦即，假设兩爾夫球在i秒内移動1〇m，則高爾夫球是在】χΐ〇名秒 201105390 内移動 1 χ HT5 m (即 0.01 mm)。 假設第一 LED部310及第二LED部320是以約100微秒交替閃燦’ 且高爾夫球速度為1〇 m/s’則高爾夫球在1〇〇微秒内只移動約lmm(當第一 LED部310及第二LED部320閃爍一次）。 結果，可精確感測高爾夫球。為進一步改善高爾夫球感測能力，亦即 精確度，第一 LED部3〗0及第二LED部320交替閃爍的循環可設定成小 於約100微秒。此時，即使高爾夫球移動很短距離，也可感測高爾夫球， 藉以進一步改善感測精確度。 較佳地，高爾夫球是放在假想線的預設位置上，且該假想線係穿過光 路徑L12及光路徑L21相互交又的交又點(光路徑L12及光路徑L21實際 上不會相互交叉，因為第一 LED部310及第二LED部320係交替閃爍）。 當高爾夫球是以Θ角度敲擊時’高爾夫球常常穿過光路徑L11及光路 徑L12，如第6圖所示。此時，第一 LED部310所發射的光線會被高爾夫 球遮斷’結果是光線無法被第一光接收部210及第二光接收部220接收， 因而高爾夫球被感測到。 在高爾夫球穿過光路徑L11及光路徑L12後，高爾夫球接著穿過第二 LED部320所發射光線的光路徑L21及光路徑L22，如第7圖所示。 第一 LED部310及第二LED部320的交替閃爍以及第一光接收部21〇 及第二光接收部220所進行的光線接收係顯示於第8圖。 在第8圖中，元件符號E1代表第一 LED部310的LED單元，且元 件符號E2代表tLED部320的LED單元。元件符號D1代表第一光接 收部210的光接收單元，且元件符號〇2代表第二光接收部22()的光接收 單元。 tEi代表LED單元E1打開的時間間隔，而b

Further, the light emitted by the second LED portion 320 is guided by the second light guiding portion 322 to form the light path L21 and the light path L22. At this time, the individual light paths are light paths along which the light emitted by the first LED portion 310 and the second LED portion 320 is received by the first light receiving portion 210 and the second light receiving portion 220.

Referring to Figure 4, a sensing device in accordance with another embodiment of the present invention will be described in detail. In the sensing device shown in FIG. 4, the first sensor unit 2 is configured such that the first light receiving portion 210 and the second light receiving portion 220 are disposed in the first sensor box 2〇1 in. As shown in FIG. 4, the first light receiving portion 210 and the second light receiving portion 22 can be exposed to the outer portion 201105390' such that the light emitted by the first LED portion 310 and the second LED portion 32 can be directly used by the first light. The light receiving unit 210 and the second light receiving unit 22 are received. Alternatively, the first light receiving portion 21 and the second light receiving portion 220 may be disposed in the first sensor box 2〇1 t, and the plurality of through holes may be in the first sensor box 2〇1 The light rays emitted by the first LED portion 31 and the second coffee portion 32 are formed so as to be received by the first light receiving portion 2 and the second light receiving portion 22 through the through holes. On the other hand, the first sensor unit 300 is preferably configured such that the first led portion 310 and the second LED portion 32 (four) flat plate 33 are disposed in the second sensor box 3〇. Moreover, the second sensor box 301 is preferably provided with a first light guiding portion 3na and a second light guiding unit 311b for guiding the broad light emitted from the first LED portion 310. The light can be radiated to the first light receiving portion 210, and the second light guiding portion 31 is used to guide the light emitted from the first LED portion 31G so that the light can be radiated to the second light receiving portion 22A. The first light guiding portion 311a and the second light guiding portion 311b are located at positions corresponding to the first LED portion 310 of the second sensor case 3〇1. In addition, the second sensor box 301 is preferably provided with a third light guiding portion 322a and a fourth light guiding portion 322b for guiding the broad light emitted from the second LED portion 320. The light can be radiated to the first light receiving portion 210, and the fourth light guiding portion 32213 is used to guide the light emitted from the second LED portion 320 so that the light can be radiated to the second light receiving portion 220. The second light guiding portion 322a and the fourth light guiding portion 322b are located at positions corresponding to the second LED portion 320 of the second sensor box 301. The first light guiding portion 311a limits the range of light emission such that the light emitted by the first LED portion 31 is guided to the first light receiving portion 210' and the second light guiding portion 311b limits the range of light emission such that the first LED portion The light emitted by 310 is directed to the second light receiving portion 22A.

The light emitted from the first LED portion 310 is transmitted to the first light receiving portion 21, and the light is guided by the first light guiding portion 31a to form the light path L11. Further, the light emitted from the first led portion 310 is transmitted to the second light receiving portion 220, and the light is guided by the second light guiding portion 311b to form the optical path L12. On the other hand, the light emitted from the second LED portion 320 is transmitted to the first light receiving portion 210, and the light is guided by the third light guiding portion 322a to form the light path L21. Moreover, the light emitted from the second LED portion 320 of 201105390 is transmitted to the second light receiving portion 220, and the light is guided by the fourth light guiding portion 322b to form the light path L22. At this time, it is preferable that the light rays passing through the individual light guiding portions 311a, 311b, 322a, and 322b are in a small range. For example, the individual light guiding portions 311a, 311b, 322a, and 322b may be sized and shaped such that light can be sufficiently transmitted to the individual light receiving portions 2 and 220 via the individual through holes 211 and 222. Hereinafter, a control system of a sensing device according to an embodiment of the present invention will be described in detail with reference to FIG. As shown in FIG. 5, the first LED portion 310 and the second LED portion 320 are connected to the regulator R' and the first light receiving portion 210 and the second light receiving portion 220 are connected to the controller Μ»the regulator R can be The first LED portion 310 and the second LED portion 320 are alternately flashed at preset time intervals. When the golf ball is sensed by the individual first light receiving portion 21 and the second light receiving portion 22, the moving direction or movement of the golf ball is calculated. At speed, the controller measures the time value and will detail it later. The first LED portion 310 and the second LED portion 320 are connected to the regulator R, and the first light receiving portion 210 and the second light receiving portion 220 are connected to the controller μ, as shown in FIG. 5, but The one LED unit 310, the second LED unit 320, the first light receiving unit 210, and the second light receiving unit 220 can be controlled by a single control unit. That is, as shown in Fig. 5, the regulator R and the controller Μ can be individually set so that the regulator R and the controller Μ perform independent functions. Alternatively, the regulator R and the controller can be integrated into a single control unit. 6 and 7 are schematic views showing the principle of sensing the movement of the golf ball by the sensing device according to the embodiment of the present invention. As shown in FIGS. 6 and 7, the first LED portion 310 and the second LED portion 320 are alternately flashed at very short time intervals (number traces to tens of microseconds (10-6 seconds)). The ball can pass through the light, Lll, L12, L21 and L22 and is detected without any difficulty. When the golfer pushes the golf ball, the golf ball moves very slowly. Example = Golf ball has a speed of 1 〇 m / s or less. The golf ball can move faster, but the speed of the golf ball does not exceed the above values. That is, assuming that the two balls move 1 〇m in i seconds, the golf ball moves 1 χ HT5 m (ie 0.01 mm) within the χΐ〇 秒 201105390. Assuming that the first LED portion 310 and the second LED portion 320 are alternately flashed at about 100 microseconds and the golf ball speed is 1 〇 m/s', the golf ball only moves about 1 mm in 1 microsecond (when the first One LED portion 310 and the second LED portion 320 blink once). As a result, the golf ball can be accurately sensed. In order to further improve the golf ball sensing capability, i.e., accuracy, the cycle in which the first LED portion 3 "0" and the second LED portion 320 alternately blink may be set to be less than about 100 microseconds. At this time, even if the golf ball moves a short distance, the golf ball can be sensed, thereby further improving the sensing accuracy. Preferably, the golf ball is placed at a preset position of the imaginary line, and the imaginary line passes through the intersection of the light path L12 and the light path L21 (the light path L12 and the light path L21 are not actually The two LED portions 310 and the second LED portion 320 are alternately flashed. When the golf ball is struck at a corner, the golf ball often passes through the light path L11 and the light path L12 as shown in Fig. 6. At this time, the light emitted by the first LED portion 310 is blocked by the golf ball. As a result, the light is not received by the first light receiving portion 210 and the second light receiving portion 220, and thus the golf ball is sensed. After the golf ball passes through the light path L11 and the light path L12, the golf ball then passes through the light path L21 and the light path L22 of the light emitted by the second LED portion 320, as shown in FIG. The alternate blinking of the first LED portion 310 and the second LED portion 320 and the light receiving by the first light receiving portion 21A and the second light receiving portion 220 are shown in Fig. 8. In Fig. 8, the symbol E1 represents the LED unit of the first LED portion 310, and the element symbol E2 represents the LED unit of the tLED portion 320. The symbol D1 represents the light receiving unit of the first light receiving portion 210, and the symbol 〇2 represents the light receiving unit of the second light receiving portion 22(). tEi represents the time interval at which the LED unit E1 is turned on, and b_匕 represents the time interval at which the LED unit e2 is turned on. In Fig. 8, tE5 · tE4 = ^ The interval between the 旲 E1 and the TM unit E2 is very short (in microseconds). The time interval between ί1 and the time interval at which the LED unit E2 is turned on is not the same. Preferably, the time interval at which the LED unit E1 is turned on is f and as in Fig. 8, the (4) is the LED unit E & 201105390 τ , the flicker interval interval τ is set to 5G microseconds or less. The best accuracy is obtained when the steel is broken to about 10 microseconds. ...a interval cycle time =:==: ° microseconds 'better, D2 production order ^ 屮 open, light receiving unit D1 and light receiving unit orders == receiving (10) generated relative to time tR4.tR = « When the 'light junction 6 疋 control LED is earlier than the EU open time interval and the LED unit E2 snoring time interval is substantially the same. The result, -tR1 = tR4 · tR3. As early as 7" E2 is turned on and as shown in Fig. 8, it is preferable that the light receiving unit 〇1:= is pulsed, and the pulse has a width which is equal to or greater than == 疋E2 is opened for the time width. And LED early single m8 riding show 'from the coffee unit ei off to the light receiving unit and light receiving axis coffee led unit E2 hit the light receiving unit microseconds. 70 The time between the output changes to G) The face is substantially equal to or greater than 1 light connection #LED material Ei and led section e2 open individually less than 1 microsecond. 11, the time interval of the early D2 output output, preferably the substantially Gaulle diagram, FIG. 1 is a detailed description of the sensing device according to the embodiment of the present invention. The time u 3, t2, ... of the ball 1 3 = 1 to L22, and the moving direction angle θ and the moving speed v of the ball 1 from the time value. It is the accuracy of the time u, t2, t3 and t4 to be measured. W H f sets the distance A to be approximately 〇·lm, and the distance B is approximately 〇.2m. When the Gore has a speed of _, the maximum degree of Dalian due to the sacrifice is 10m/s. 201105390 When the accuracy of the moving direction angle θ of the golf ball is 1/100 of the angle between the center line c and the first 210, t32/(4) must have 1 〇/. Or smaller value of the medium ^ ^, t32 = t3 -12 and t41 = t4-tl. The accuracy with which t32/t41 must have a value of 1% or less means that t32 must have a precision of 丨, and t41 must have an accuracy of 1% or less. 〇3 When the maximum speed of the golf ball is 10m/s, t41 can have a maximum value of 〇1 second. In order to achieve 1% accuracy, the time required for the golf ball to move from the light path L11 to the light path U2 requires the accuracy obtained by dividing 0.01 seconds into one hundred equal parts, that is, 〇〇〇〇〇1 second (1〇) 〇 microseconds ^ Result 'The interval between opening, closing and opening of the first and second LED sections, that is, the cycle: r, about 50 microseconds. The cycle Τ can be set to less than 50 microseconds to further improve the accuracy. However, if the loop Τ is too short, the loop Τ is actually meaningless. Therefore, the above situation must be considered to set the loop τ. 4 After that, the angle of the moving direction of the golf ball is calculated from the individual times tl, t2, t3 and t4. The mathematical mode of θ and the moving speed V will be guided according to the trigonometric function and referring to Fig. 9 and Fig. 1. As shown in Fig. 9, the distance between the starting position of the golf ball 1 and the light path L11 is assumed. For D, the distance between the light path L11 and the light path L22 is A, and the distance between the first sensor unit 200 and the second sensor unit 300 is 2B. The center line C and the first sensor unit The distance between 200 is substantially B. Moreover, the center line C and the number The distance between the sensor units 3A is substantially B. It is assumed that the angle between the light path L11 and the light path L12 is β. At this time, the angle between the light path L21 and the light path L22 is β. It is assumed that the angle between the center line C and the first light receiving portion 210 is α, the moving direction angle of the golf ball is Θ ' and the moving speed of the golf ball is V. Here, 'A, Β, D, α, and β are pre- Fig. 10 is a view showing the light path L11 and the light path L12 of Fig. 9 in more detail. It is assumed that the instantaneous position ti of the golf ball 1 passing through the light path L11 and the instantaneous position t2 of the golf ball 1 passing through the light path L12 The distance between d is the vertical distance between the instantaneous position t1 and the instantaneous position t2 and the vertical distance between the instantaneous position t2 and the second sensor unit 3 is h. 12 201105390 The following equation can be derived. *C〇S0=:lh*tan/3 = ih = D*tana-(D + l)*tan0 When Equation 2 is brought into Equation 3 _ ^ * tan/? * (tanor - tan l + tan^*tan^ Equation 1 Equation 2 Equation 3 derives Equation 4.

"here't21=t2-tl and t31=t3-tl. That is, t2i is the time from the golf ball passing through the light path L11 to the passage of the golf ball through the light path L12, and 〇1 is the time from when the golf ball passes through the light path L11 to when the golf ball passes through the light path L21. Since t31 -121 = t3 -12 = t32, Equation 7 can be arranged as: V*e2* cose = l-b*tan20 Equation 8 where k = 1 + tanp * tana and b = tan2p. Meanwhile, as shown in Fig. 9, the distance A is expressed as the following equation.

In the equation ίο +, the time t is the measured value (4) and t41 is a value that can be easily obtained by measuring the time u 'port, t3 and t4), and N and b are constant or predetermined values, which are constants. Therefore, the equation l〇Sx quadratic equation. The solution of Equation 1 of Figure 1 is obtained as shown below. ~Tujiayou--JTb- Equation 11 Since the moving direction angle θ of the golf ball does not exceed 90 degrees, x(= tane) has a positive value. When the N and b of the preset value and the t of the measured value are brought into the equation n, χ is calculated. Since Θ = tar^x ', the moving direction angle θ of the golf ball is calculated. ... When the moving direction angle θ of the golf ball is calculated, the moving speed of the golf ball can be calculated by Equation 9. At the same time, as described above, the golf_moving direction angle and the moving speed calculated by the mathematical mode are calculated by the assumption of the shirt. As a result, the calculated (four) degrees and speeds are different from the actual angles and speeds. That is, the calculated jitter and velocity have such errors that can be appropriately corrected by many experiments and simulations to derive the final experimental equation. As long as the time value is measured when the golf ball passes through the side light path, the angle and speed of the golf ball can be more accurately obtained according to the experimental equation bound by the phase error of the fresh mode as described above. . Many embodiments of the sensing device of the push rod simulation device and its sensing method have been described in the best mode for carrying out the invention.
