Description of the invention: [Technical field to which the invention pertains] The deflection state produces a correction value in what kind of weighting, especially the return-off state, and according to its [prior art], the load cell is a kind of measuring object Heavy basics such as weight scale, pricing, counting scales, platform scales, ancient i cattle red illusion are also used in the people's livelihood and industrial fields, 譬, leather π scales, floor scales, barrel scales and various industrial scales. Take the application of the weighbridge station as an example. Every pound must be adjusted to the level of the individual load to make it more than 8 load cells. Every load-weight is divided by the direction of gravity. If it is (four) (beyond the cause), it must be noted to maintain its axis distortion. If it is skewed after use, its sensed value will be broken. Under the platform of the load iff two (four) Taiwan after the heavy pressure, shaking the strong impact, it is difficult to avoid the occurrence of loose or mechanical friction to detect whether there is a load under the broken table is right. 2 no effective method anytime Deviation unless someone goes to the table to check the I. For the calibration method of the station, the standard embossing weight is applied to the table to calibrate the value, and the effect of - is only a general correction. Can not "for the individual load: + ton shop (four) the most cut up to several tons, the number (four) in the surplus turn up to touch, and the _ _ error miscellaneous material is slanting. There is a business ^ for the An 4 operation can not be each new - a load weight can not be the slightest deviation of the 200918871 equipment accuracy. In addition, if individual corpses can be used, the adjustment and correction work of the simplification of the smashing and heavy equipment can be completed and the purpose of "returning the deviation of the slanting situation" can be achieved, and the lion will be mistaken in the past. SUMMARY OF THE INVENTION The meta-sensing early element, the dip sensing element, and the unit is mounted in a casing-loading data transmission interface unit, electrically connected to the second calibration and skew compensation arithmetic unit, weight Digital signal. Miscellaneous way (four) - Na "concurrent material - on behalf of the actual - sensory record, read and biased to = _ material _ - material weight generated by wired or wireless 磐 transmission interface r / eQM ^ The obtained value is the correction value W, the number j. The output represents the digital signal of the angle Θ and the skew correction value w. [Embodiment]: The advantage of the === can be more clearly _, the following is a better implementation of the gravitational direction Gθ In the skewed shape of the tW. Because the axis and the like, the sensory Wr is less than the actual load weight. Installation - load sensing "This digital load cell 2, including within the chassis 2 ° at least , a data element single compensation unit 22, a tilt sensor element measurement - weight And outputting a power supply 26 and electrically connecting each other to generate a W digital signal representing a correction value of the actual weight $. The local measurement unit 21 can be used by a strain gauge bridge and a device. The digit of the second-order rotation measured by the strain gauge is input to the arithmetic unit 22 of the calibration and skew compensation. 200918871 As shown in Fig. 3, the tilt sensing element 23 can be a three-axis acceleration gauge. It is fixed in the casing 2〇. Its working principle is: when the body of the accelerometer moves or rotates, the internal microstructure is displaced, causing a change in the capacitance value, which is converted into a specific output voltage as a signal. 4 shows that the three-axis accelerometer of the tilting sensing element 23 has an X-axis, a _ γ-axis, a Z-axis, and a sensitivity value Sa. The three-axis accelerometer outputs when the X-axis and the γ-axis are on a horizontal plane. The sensing voltage values of μ and Y1, in the Z-axis direction and the gravitational direction G of the gravitation, the sensing voltage of Z1 is turned on. In other words, when the triaxial accelerometer is in an unbiased state, the x-axis and the y-axis are positive. In the horizontal plane, when the z-axis is in the direction of gravity, the sensed output of the output is The values are XI, Y1 and zi. When the X-axis and γ-axis of the two-axis accelerometer deviate from the horizontal plane, the χ and γ axes are respectively changed to X, the axis and Υ' axis are represented, and the outputs of Χ2 and Υ2 are sensed. The voltage value; when the ζ axis deviates from the gravity center, it is represented by the Ζ' axis, and outputs the sensing voltage value of Ζ 2. The following values can be performed by the dip tree 23 or the calibration and skew compensation operation unit 22. Extracting and calculating the amount of change in the sensed voltage when the X-axis deviates from the horizontal plane (Μ-砭); reading and calculating the amount of change in the sensed voltage when the m-axis deviates from the horizontal plane (Yi—a); Calculate the amount of electric hybridization (2) when the 2 axis deviates from the gravitational direction of the earth—for example, generate a Αχ value ' X the amount of variation in the impurity level from the horizontal plane · Generated - Ay value = the γ axis deviates from the horizontal plane Sensed voltage change amount ·; Generated - Az value = sensed voltage change magnitude when the ζ axis deviates from the gravitational direction; produces - the angle ^arctan [(, (Αχ2 + Ay2)). The method of merging the self-face of the load cell 2 includes: assigning a per-digit conversion step, whereby the oblique complement unit 22 performs - (four) valence (10) and the correction value W.曰 ' ' and output the identification code from the data transmission interface 24, the angle 0 through the data transmission interface 24, can be used to input a recognition code by wired or wireless transmission, 6 200918871 ::= set value, three-axis acceleration gauge The sensitivity value - zero setting and other parameters of the compensation = material element 22 can be - the implementation of the upper disclosure of the micro-service, to - provide the scale and skew compensation operation, and the capital = _ positive value W, - The _ _ _ ί ί 减 减 减 减 减 减 减 减 减 减 减 减 减 减 减 减 减 减 减 减 减 减 减 减 减 减 减 减Shibiantai 2 under 5 Γ 4; Touching element 2 Wei turn her number «distributed in a w 隹 隹 Ί 将 将 个别 个别 个别 个别 个别 个别 个别 个别 个别 个别 个别 个别 个别 个别 个别 个别 个别 个别 个别 个别 个别 个别 个别 个别 个别 个别 个别 个别
