RFID-based cargo management method, electronic device and system

Abstract

The embodiment of the invention provides an RFID-based cargo management method, an electronic device and a system. The method comprises the steps of acquiring the distance, collected by an ultrasonicsensor, between front goods and goods collection equipment; determining the collected time period of the goods according to the distance; acquiring the signal intensity and the signal phase value of each cargo label after the RFID identification equipment scans the RFID cargo label attached to the surface of the cargo in the time period; and inputting the signal intensity and the signal phase value of each cargo label into a pre-trained classifier, and determining the coding information of the acquired cargo according to the output result of the classifier. According to the embodiment of the invention, the ultrasonic sensor is used for judging collected goods; the RFID tag information is continuously acquired for a period of time during acquisition, the acquired cargo RFID tags are accurately identified according to a pre-trained classifier, threshold setting is not required, the acquisition requirements of various acquisition equipment can be met in a complex wireless environment, andthe high reliability requirement of a warehousing system is met.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technology, and in particular to a cargo management method, electronic equipment and system based on RFID (Radio Frequency Identification, Radio Frequency Identification). Background technique [0002] Warehouse management system generally adopts cargo coding technology to classify and manage goods, and usually uses barcodes, two-dimensional codes, RFID (Radio Frequency Identification, Radio Frequency Identification) and text and other media to install on goods, according to the information on the media. manage. [0003] For bulky cargo, forklifts are generally used for cargo transfer, and the storage management of large cargo is mainly divided into two schemes: traditional barcode registration and RFID-assisted barcode registration. Among them, in the management scheme using RFID technology, RFID tags are installed on each large-scale cargo, and RFID identification equipmen...

AI Technical Summary

Problems solved by technology

However, due to the inaccuracy of the installation position of the RFID tag and the uncertainty of the position of the forklift to pick up the goods, it is difficult to call out a suitable threshold. Considering that in actual scenarios, it is usually inevitable to require forklifts to pick up multiple layers of goods At this time, the goods in the back row will be blocked by the goods in the front row, resulting in a weak signal. The method of adjusting the threshold value is not available for this kind of scene.
