Intelligent weighing method based on RFID

Abstract

The invention provides an intelligent weighing method based on RFID. According to the method, electronic scale equipment used for acquiring the article weight data, an RFID label, an RFID label ID information reader, display equipment and industrial control computer equipment are utilized, wherein the industrial control computer equipment is separately connected with the electronic scale equipment, the RFID label ID information reader and the display equipment. When an article is put on the electronic scale equipment for weighing, the electronic scale equipment is used for stably acquiring the article weight data which is transmitted to the industrial control computer equipment, the RFID label ID information reader is instantly trigger to read a label ID of the article after the data of the electronic scale equipment is acquired by the industrial control computer equipment, the label ID and the weight data are both sent by the industrial control computer equipment to an article information data database, and the information is logically analyzed by a background server system and is then further displayed to users through a webpage and short messages. The method is advantaged in that work efficiency of workers is greatly improved, and management cost is saved.

Description

technical field [0001] The invention relates to an RFID-based intelligent weighing method. Background technique [0002] Radio Frequency Identification (RFID) is a non-contact automatic identification technology. It automatically identifies the target object and obtains relevant data through radio frequency identification. The identification work does not require manual intervention and can work in various harsh environments. RFID technology can identify high-speed moving objects and can identify multiple tags at the same time, which is convenient and quick to operate. [0003] For a long time, the management of weighing items and item weight data has been a difficult problem in coal, cement, fossil, grain, feed, metallurgy, chemical industry and all industries that require weight data. In order to effectively manage it, enterprises usually use infrared recognition and video recognition to trigger the reading of RFID tags or use traditional barcode technology, and some only...

AI Technical Summary

Problems solved by technology

Infrared and video recognition technologies are inefficient and have a high error rate

The traditional barcode technology uses the photoelectric effect, and uses the barcode reader to convert the photoelectric signal into an optical signal, and then read the information stored in the barcode. However, this method often requires the barcode to be close enough to the recognizer to be recognized, so it is not very fast to use. , the efficiency is low, and it cannot meet the needs of large enterprises for item weight management
