RFID-based rapid automated weighing system

Abstract

The invention discloses an RFID-based rapid automated weighing system. A data acquisition module comprises an electronic scale and a piece of RFID equipment, which are respectively used for acquiring weight information and hook tag information. A mechanical module comprises a guide rail and a sling, an electronic scale sensor is installed on the guide rail, RFID equipment antennas are respectively installed at the two sides of the guide rail, and a hook is movably arranged on the guide rail. The weight on the guide rail is transferred to the electronic scale sensor, and an RFID reader-writer identifies an electronic tag on the hook through the antennas. An information processing module converts the acquired hook tag information into a hook number, associates the hook number with the acquired weight information and outputs a complete weighting record. An information output module provides a friendly man-machine interactive interface, and gives a warning for abnormal conditions or suggests other information through a warning maker. The RFID-based rapid automated weighing system has the advantages of automated weighing management, high weighing speed, accurate weighing value, high system compatibility, strong versatility and easy installation and can be used for weighing in many fields.

Description

technical field [0001] The invention relates to the technical field of RFID, in particular to an RFID-based rapid automatic weighing system. Background technique [0002] The traditional weighing system has a single composition and structure, usually including only one electronic scale. After weighing the item, the operator manually enters the weight value and item identification into the computer. The weighing process is not only time-consuming and has large errors, but also easily breeds fraudulent behavior by operators, causing economic losses to the owners. [0003] In recent years, many automatic weighing systems have been produced. They automatically identify the identification information of the weighing object based on RFID technology, use intelligent electronic scales to weigh the weight, and realize the automatic transmission of RFID information and weight to the computer through the network, curbing the fraud of operators. Behavior. However, these systems have ...

AI Technical Summary

Problems solved by technology

[0004] (1) After reading the RFID information, the reader needs to communicate with the computer to further extract effective and useful information. This process affects the response time of the entire system

[0005] (2) The weighing value is an approximate value calculated by the software in the system, with large errors and time-consuming

[0006] (3) The high degree of customization of equipment in each link of the system makes the system incompatible with equipment of different brands and lacks flexibility

[0008] Although the above-mentioned patented technology also uses RFID-based technology, it cannot realize an automated complete system and needs further improvement.
