Abstract
A method for calculating the quantity of goods based on weighing includes the following steps: Step 1, Weight Conversion; accurately convert the weighing reading to the corresponding weight value W; Step 2, Weight Scaling; that is, the conversion of weight units; Step 3, Zero Point Correction; calibrate the weight reading; Step 4, Tare; remove the weight of non-goods objects in the weight value; Step 5, Anti-Mutation Filtering; anti-mutation filtering on the weight value; Step 6, Quantity Conversion; convert the weight value after calibration and correction of steps 1 to 5 above into the approximate (rough) quantity of the goods; Step 7, Quantity Calibration; calibrate the rough quantity of the above-mentioned goods.
Claims2
A method for calculating the quantity of goods based on weighing, comprising:
- performing a zero-point correction method that calibrates weight reading, wherein the zero point correction method is zero point automatic follow-up calibration;
- when a pallet is in an unstable state, automatically recording and adjusting normal weight changes caused by shipment and purchase of goods,
- checking the weight of the goods;
- and
- if after compensating for the normal weight change, delta of at least a preset number of consecutive sampling readings after the compensation falls within a range of [ZPTMIN, ZPTMAX], accumulating a mathematical average or a weighted average of consecutive sampling variations to a zero point offset compensation amount, where ZPTMAX is a maximum following step value, and ZPTMIN is a minimum following step value.
