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.
Claims9
A method for calculating the quantity of goods based on weighing, which is characterized by:
- Includes zero point correction method to calibrate the weighing reading;
- When the system detects that the current pallet has been emptied, but the weighing reading has not returned to zero, after at least a preset number of consecutive sampling readings fall within the weighing reading threshold (ZPT) range, the ZPCS continuous samples are averaged in a weighted form, and save this value as the new zero point offset compensation amount (ZPO).
A method for calculating the quantity of goods based on weighing, characterized in that it includes a zero-point correction method, calibrate the weight reading;
- The zero point correction method is zero point automatic follow-up calibration, when the pallet is in a stable state and the delta of at least a preset number of consecutive sampling readings falls within the range of [ZPTMIN, ZPTMAX], accumulate the mathematical average or weighted average of consecutive ZPTCS sampling variations to the zero point offset compensation amount (ZPO), the ZPTMAX is the maximum following step value, the ZPTMIN is the minimum following step value.
A method for calculating the quantity of goods based on weighing, characterized in that it includes a zero-point correction method, calibrate the weight reading;
- The zero point correction method is zero point automatic follow-up calibration, when the pallet is in an unstable state, it automatically records and adjusts the normal weight changes caused by the shipment and purchase of the goods, then check the weight of the goods, if after compensating for the above-mentioned normal weight change, it is detected that the delta of at least a preset number of consecutive sampling readings after the compensation falls within the range of [ZPTMIN, ZPTMAX], accumulate the mathematical average or weighted average of consecutive ZPTCS sampling variations to the zero point offset compensation amount (ZPO), the ZPTMAX is the maximum following step value, the ZPTMIN is the minimum following step value.
