An RFID-based express logistics automatic sorting system and its sorting method

Abstract

The present invention provides an RFID-based express logistics automatic sorting system. The system includes an information acquisition device and a sorting execution device. The information acquisition device includes a bar code reader, an RFID reader, an on-site computer and a server. The execution device includes a core industrial computer, a PLC controller, a gate-type RFID sensor and a displacement sensor set at the entrance of the sorting conveyor, several sorting diverters set at the exit of the sorting conveyor, and each sorting diverter. on the relay. The invention also provides a sorting method of an RFID-based express logistics automatic sorting system. The present invention only needs one sorting to complete the sorting of the package to the delivery area, which greatly reduces the operation links, improves the sorting accuracy, reduces the belt conveyor investment and manual input, greatly accelerates the processing speed, and greatly enhances the processing capacity. , which can bring better benefits to express logistics enterprises.

Description

technical field [0001] The invention relates to the technical field of express logistics sorting automatic control, in particular to an RFID-based express logistics automatic sorting system and a sorting method thereof. Background technique [0002] Most of the existing courier companies use manual or semi-automatic sorting methods. From unloading to the final departure of the sorting center, the package needs to be recognized by human eyes many times. It requires many workers, high labor intensity, low sorting efficiency, high cost and error-prone. Although some courier companies use automatic sorting, what they read is the barcode on the courier bill. Due to the contamination of the barcode during transportation and the lack of accuracy of the reading and writing equipment, the barcode is used as an identification mark for automatic sorting. Although in tobacco, Single-standard product fields such as pharmaceuticals and printing have been applied, but in the face of the di...

[0002] Most of the existing courier companies use manual or semi-automatic sorting methods. From unloading to the final departure of the sorting center, the parcels need to identify information with human eyes many times, using many workers, high labor intensity, low sorting efficiency, high cost and error-prone

Although some courier companies use automatic sorting, what they read is the barcode on the courier bill. Due to the contamination of the barcode during transportation and the lack of accuracy of the reading and writing equipment, the barcode is used as an identification mark for automatic sorting. Although in tobacco, Single-standard product fields such as pharmaceuticals and printing have been applied, but in the face of the diversity, large flow, and low barcode recognition rate of express logistics packages, it is difficult to fully apply the barcode-based automatic sorting system
