Embodiment 1

[0018] Applying this system to the meat wholesale trading market, the principle is to use RFID radio frequency identification technology to realize automatic identification of the carrier of the identified object, and the electronic tag is attached to the carrier of the identified object. Entering the readable range of the reader, the RFID radio frequency reader will automatically read the agreed information in the radio frequency tag in a non-contact manner, thereby realizing the functions of automatically identifying items and collecting item identification information.

[0019] To achieve the above principle, please refer to the figure 2 , the system consists of:

[0020] (1) Industrial computer, the industrial computer can adopt dual-core 2.8G model Sockets775, 1000M adaptive network, 2 RS-232 serial port processors and DDR2 667 2G memory configuration or ANOVO processor model E5800 ;

[0021] It is an operable function interface compiled by using VB programming tools o...

Abstract

The invention relates to the technical field of remote data collection, transmission and processing, in particular to an RFID (radio frequency identification device) automatic identification on-line dynamic rapid weighing control system and a control method thereof. The control system comprises an industrial computer, an operable functional interface, a display screen, a PLC (programmable logic controller), an RFID radio frequency reader-writer, an exchange board, a weighing instrument, a weighing sensor and a power source. The control system is characterized in that output signal lines of the weighing sensor are connected with signal input lines of the weighing instrument; the output signal lines of the weighing instrument are connected with a signal input end of the industrial computer COM2; three signal input lines of the industrial computer are respectively connected with the RFID radio frequency reader-writer and the exchange board through network communication ports, and connected with communication port signals controlled by the PLC through a COM1 signal input end; a VGA (video graphics array) end of the industrial computer is connected with the signal input end of the display screen; and data processing, storage, counting, exchange, display and transmission are carried out through a VB (visual basic) programming tool. With the adoption of the RFID automatic identification on-line dynamic rapid weighing control system and the control method thereof, the trade statistic information cost and the labor cost are greatly reduced, the working efficiency and the information accurate rate are greatly improved.

Description

[technical field] [0001] The invention relates to the technical field of remote data collection, transmission and processing, in particular to an RFID automatic identification online dynamic rapid weighing control system and a control method thereof. [Background technique] [0002] In the traditional meat wholesale trading market, weighing and measuring operations are all processed manually, and are completed and submitted through manual information entry, which makes the transaction statistical information high cost, low efficiency, error-prone, and many disputes and other situations. [0003] Therefore, the current meat wholesale trading market is trying to integrate related technologies such as RFID radio frequency identification technology, automatic control technology, computer technology, and network communication technology into a comprehensive system of automatic identification, automatic weighing, automatic data processing, and automatic information transmission.
