A sorting method for a code scanning, weighing and volume measuring all-in-one machine is characterized by comprising a DWS system and an embedded control system, and further comprising the code scanning, weighing and volume measuring all-in-one machine as claimed in any one of claims 1 to 7, wherein a starting transport platform is placed on the left side of the weighing platform, a receiving transport platform is placed on the right side of the weighing platform, a photoelectric sensor for detecting whether an article passes through is arranged on the starting transport platform or the weighing platform, the photoelectric sensor is arranged at a position close to the right of the starting transport platform or a position close to the left of the weighing platform, an ending photoelectric sensor is arranged on the weighing platform, and the ending photoelectric sensor is arranged at a position close to the right of the weighing platform;
the sorting steps are as follows:
A. after detecting a logistics package, the photoelectric sensor sends a trigger signal to the embedded control system, and the embedded control system judges whether the logistics package is triggered by mistake;
B. if the embedded control system judges that the triggering is not false triggering, sending a starting signal to the DWS, and enabling the DWS to start collecting the data of the bar code, the volume and the weight and judging whether the data collection is finished or not; if the embedded control system judges that the trigger is false, the start signal is not sent to the DWS system;
C. if the data is not acquired, an abnormal alarm is given; if the data acquisition is finished, comparing the acquired data with corresponding data stored in a local cache, and if the bar code, the volume and the weight data do not correspond to the corresponding data stored in the local cache, performing abnormal alarm; and if the bar code, the volume and the weight data correspond to corresponding data stored in the local cache one by one, the packages flow out to the receiving transport table, the embedded control system sends an end signal to the DWS system, and the initial transport table is controlled to transport the next package to the weighing table.
9. The sorting method according to claim 8, wherein if the bar code, volume and weight data are not collected, the bar code, volume and weight can be observed manually after alarming, missing data can be collected manually, and the missing data are recorded into a DWS system and then wrapped for next data comparison.
10. The sorting method according to claim 9, wherein the photoelectric sensor is a split photoelectric sensor disposed at a position to the right of the origin transportation table; a starting photoelectric sensor is arranged on the left side of the weighing platform, the starting photoelectric sensor is 30-50mm away from the left end of the weighing platform, and the ending photoelectric sensor is 30-50mm away from the right end of the weighing platform; when the initial photoelectric sensor senses that the articles on the weighing platform pass through, the initial photoelectric sensor sends a trigger signal to the embedded control system; when the photoelectric sensor does not sense that the articles on the weighing platform pass through, the articles on the initial transport platform stop moving at the position of the split photoelectric sensor.
