Description of the invention: [Technical field to which the invention pertains] ^ Γ Γ is concerned with a charge of 4 yuan, especially a person who can report its skew state and generate a correction value according to its skew state. [Prior Art] 2 yuan is a kind of measuring material heavy lining this component, regardless of the people's livelihood and industrial fields, such as weight scale, pricing, counting scales, platform scales, belt scales, (four), barrels and various industries Use kind and so on. For example, the application of the ground crushing station is to install 6 to 8 load cells per broken table. In addition to the load-bearing weight of each load, it is necessary to pay attention to maintaining the direction of gravity. If there is deflection during installation or after use, the sensed value will be different. Pressure, wire and strength _, displacement deflection under the action of the load or mechanical friction under the shot. _ No effective method at any time = know that under the hood, the shirt has a load-bearing hairline, unless someone is going to carefully check the green 'over the touch of the fresh 阙 « pure value, this occurs LLi alignment For example, the application of large buckets for individual load cells is taken as an example. Some bucket scales have a maximum weighing range of up to several sneakers and a sufficient number of interviews. It is difficult to use standard broken code weights to calibrate, even if there are The standard station code, and there is no description of the madness of the second station code, so tuning has become a headache. Due to the difficulty of calibration, the current 曰, '' (4) error tolerance range is as high as 1/5GQ, while the mantle error is only 00. oblique. Some people's t-installation can't guarantee that every load can have no slight deviation. If its axis is skewed and corrected in the partial step, it will greatly improve the weighbridge, barrel scale, etc. Large measurement 4 1345627 j accuracy. In addition, if individual load cells can be adjusted at any time = (four) heavy equipment adjustment and calibration work and maintenance work, even can achieve the = = shape. ^ Can be a big purpose and easily prevent mistakes before they happen. Mp can be completed [invention content] A ^ ^ ^ yuan meets the above-mentioned industry expectations and ardent improvement needs, can return and compensate for its axis deviation from the center of the heart - the load-bearing heavy sensing unit, sensing The component's - load and - data transmission interface unit, the electrical diagonal complement of the arithmetic unit, the weight of the digital signal. New connection financial formula H has no «and_- represents the actual return of the load cell of the present invention and self-compensation method r-line or wireless_interface division] =;; == [Embodiment] The above-mentioned purpose of the invention is characterized and The advantages can be more ambiguous, the following is a better implementation of the benefits, and with the accompanying drawings, the detailed description is as follows: 权住贯地,,,,,,,,,,,,,,,,,,,,,,,,,, ®. Since the axis of gravity of the axial blood has a gamma angle of 0, the sensed value is less than the actual load. The glaze is a digital load cell 2 of the invention, including at least 2 ΓΓΙ=ΐΓ in the casing 20 [the operation unit 22 of the calibration and skew compensation, ·丨〗 interface early 70 24, " ~ memory unit 25 and - power supply 26, electrically connected to each other (four) - shop weight and output - represents the actual amount of correction _w digital signal. Example of the load sense S 21 can be - strain gauge bridge (strain gauge bridge), one - touch / digital converter to achieve, with the change of the strain measured by the turn signal than the signal, ''', although the number of Wr complement, the input and bias The operating unit of the bevel 22. 5 1345627 * As shown in Fig. 3, the tilt sensing element 23 can be a three-axis accelerometer fixed within the casing 20. The working principle is: when the body of the accelerometer moves Or the 'internal microstructure generates displacement' when rotating, causing a change in the capacitance value, which is converted into a specific output voltage as a signal. As shown in Fig. 4, the three-axis accelerometer of the tilt sensing element 23 has an X-axis, a a γ-axis, a z-axis, and a sensitivity value Sa, wherein the three-axis acceleration gauge is located on the X-axis and the Y-axis ! Output χ horizontal surface and the sensed voltage value Y1 'in the Z axis direction to the gravitation direction G - When the actuator wheel out of the sensed voltage value Z1.

換言之’當三軸加速規於無偏斜狀態時,X轴與γ轴於正水平面上,其z 料於正地心引力方向時,其輸出的感測電壓值為XI,Y1及Z1。 當三軸加速規之X軸與Y軸偏離水平面時,其X軸與Y軸分別改以X,軸 與Y’軸代表,並輸出X2及Y2的感測電壓值;當其z軸偏離地心引力方向〇 時,改以Z’軸代表,並輸出Z2的感測電壓值。 夾角Θ值可藉由傾角感測元件23或校準及偏斜補償之運算單元22 下列步驟: 4取且計算出該X軸偏離該水平面時之感測電壓變化量; 讀取且计算出忒γ轴偏離該水平面時之感測電壓變化量(Y1—Μ); «貝取且计鼻出該z軸偏離地心引力方向時之感測電壓變化量(zi—Z2); 產生Αχ值玄X軸偏離該水平面時之感測電壓變化量; 產生Ay值-s亥γ軸偏離該水平面時之感測電壓變化量~ ; 產生- Az值=該Z軸偏離地心引力方向時之感測電遷變化量^ ; 產生-夾角 Cretan [(/W + Ay2))/Az]的數值。 ’ 荷重 w猎料生"'修正值W,並從f料傳輸界面24輸*識二 透過資料键φ 24峨細崎辨識碼、 1345627 一夾角⑽最大許可設定值、三軸加速規的缝值Sa,及歸零奴等參數而 儲存於記憶單元25。 校準及偏斜補償之運算單元22可為—執行上揭運算的微處理器,以一定 的^序取4讀單①25裡贿的參數提做準及偏斜猶的運算 =傳,界面24輸出代表編及修正值_時,—併對外送出個別數位^ 兀’辨識碼’供接收端的監控裝置據以識別夾角Θ及修正值w的信絲源。 ^第5騎示’本發明之數位荷重元2魏以複數個組合型態配置於一 隼對""的方式將個聽位荷重元2嶋識碼、夾角0及修正值 W匿集至-有線監控裝置4,加以顯示及記錄。 值 輸出=例包Γ計算單元4。、-記憶單⑽及- Μ开9·、t 4G 了為—執行計算的微處理器,用以將每-數位 設備42加城起來’ 單元41純_,並錢利用輸出 丄;:=接==-數位荷重元2的偏斜㈣超 聲、光設備發出信號,用以提醒操作二 發出的警訊或以其它 位荷重元2。 '、員,主愿、,以文排維修或更換有問題的數 ^ 30 一傾角感測元件33、-射二運算單元32、 電源37,彼此以電性連接的 ^早、感溫元件36及一 許可^㈣的最大 =====運 如 錢仃-修正值崎/_的轉換步驟。 個組合型態配置於一碎3的變化應用例’係能以複數 7 ’…、線傳輸的方式將個別數位荷重元 3的辨識瑪、㈣及修正值W _-無輪裝置5,加以顯示及記錄。 本運用例之有線監控裝置5, ^ 一 輪出設備52及-_收„^ j #早dL7^51、 位荷重元3的辨辦& + 置53。其中以射頻收發裝置53接收來自各個數 荷重,將社果以二二角及修正值W,藉由計算單元5〇算出碎台7上的 重將結果以爾元51儲存,利輸出設備52輸出。 可發城。健者,輸出設備52可為一 «ΐί==;=^嫩織罐A 3的電源37, 下列^明所提供之數位荷重元2與3,與其他 習用技術相比較時,至少具有 偏者不必停止碎重设備的運作,即可隨時得知各個數位荷重元的 2.
