摘要： A method for dynamically managing power consumption, as well as a wake-up method, is disclosed for a wireless weighing platform. The method is initialized by setting both light and deep sleep period, entering a normal operating state, and starting light sleep timing. As long as no weighing operation is detected and the light sleep period has not expired, the method seeks to detect the weighing operation. If the light sleep period expires with no weighing operation, a light sleep state is entered, by turning off a communication function and starting timing for the deep sleep period. If no weighing is when the deep sleep period has expired, the wireless weighing platform enters a deep sleep state, by turning off power supply other than that for an acceleration sensor. If the acceleration sensor detects an effective vibration while in the deep sleep state, the normal operating state is restarted.

摘要： A method for real-time processing of a detection signal, wherein signal processing is respectively performed when a detection signal is converted from a high level to a low level or vice versa. A moment at which a level of the detection signal is converted is recorded as a start point. A status of the detection signal is then detected in real time at a current moment. A current time width is compared to a maximum interval width of pre-set interference signals, and signal levels are determined and recorded from the start point to the current moment. Using characteristics of different interference signals, anti-interference processing is performed by using a targeted edge positioning and width recognition method, so that the delay impact of filtering on signals is avoided, improving both the recognition precision of weighing data of a checkweigher and the overall performance of the checkweigher.

摘要： A digital load cell includes: a strain bridge including a Wheatstone bridge formed by connecting four resistive strain gauges and a temperature sensing resistance element connected in series to the Wheatstone bridge. An analog-to-digital conversion circuit excites the strain bridge, and includes a plurality of input channels and an output terminal. The input channels receive feedback signals from the strain bridge, and the output terminal outputs the feedback signals after analog-to-digital conversion. A signal processor includes a load force calculation unit and a state information matrix calculation unit. The load force calculation unit calculates a differential voltage and a compensation function based on the feedback signals obtained from the output terminal, and calculates a load force value based on the differential voltage and the compensation function. The digital load cell and related weighing system; can provide comprehensive and effective real-time health state monitoring for the digital load cell.

摘要： A weighing method has an automatic micro-calibration function. In the method, an automatic adjustment is performed by a self-calibration weighing module. When the result of the adjustment does not meet a requirement, an automatic calibration is performed by the self-calibration weighing module, followed by weighing fine formulation materials. In the weighing method, the self-calibration module is used to perform the automatic calibration function to weigh the fine formulation materials. This provides a high degree of automation, and greatly reduced cost in equipment and labor for a formulating process, saving on time and labor, and with no risk of cross-contamination.

摘要： A method for configuring a calibration mechanism in a force sensor (100) has the steps of: coupling an end of the calibration lever (1071) to a loading end (102) of the force sensor; adjusting, in a no-load condition, the center of gravity (G0) of the unloaded calibration lever (1071), so that the center of gravity (G0) lies on a horizontal line (H) through the center of a calibration lever fulcrum (1031) at a fixed end (103) thereof; and adjusting, in a full-load condition, the center of gravity (G1) of the calibration lever (1071) loaded with the calibration weight (106), so that the center of gravity (G1) lies on the horizontal line (H) through the center of the calibration lever fulcrum. The calibration error caused by inclination in the force sensor is reduced by practice of this method.

摘要： In a weighing method, a weight (W) of a measured object (7) is measured. A roll angle (r) and a pitch angle (p) of a weighing scale platform (100) are read. The coordinates of a placement position (x0, z0) of the measured object are acquired. A first error (error1) caused by a weighing state according to the roll angle and the pitch angle is calculated. A second error (error2) caused by a weighing position according to the coordinates of the placement position, the roll angle (r) and the pitch angle (p) is also calculated. From these, a corrected weight (Wc) is determined.
