1、附录 B 参考英文文献 Design of a Cigarette Sorting System Based on RFID Technology Leizhang, Weixing Su, Kunyuan Hu, Lianbo Ma Key Laboratory of Industrial Informatics Shenyang Institute of Automation, Chinese Academy of Sciences Shenyang 110016, China Abstract This paper presents a design method to solve th

2、e problems of high failure rate and sorting inefficience in the current cigarette sorting system by integrating RFID technology with CAN BUS. Based on the features of high speed of data transmission, real-time and high reliability, CAN BUS intelligent node is designed. RFID technology enhances the s

3、peed and efficiency of cigarette identification. Meanwhile, using the LCD touch-screen and MCGS configuration software, the HMI operation is promoted and the visualization of monitoring processing can also be accomplished.

4、arette sorting system is the core of the logistics and distribution. Every modern logistics distribution center depends on the sorting technology and its method. Constructing an advanced sorting system with effective throughput can not only save tens, hundreds or even tens of millions of cost, but a

5、lso improve efficiency, significantly reducing the labor intensity of the workers. Traditional cigarette sorting system collects data by barcode with a low-cost, easy to read and reproduce. However, the bar code and optical scanning are easily affected by dust, oil and other pollutions in the sortin

6、g field, and traditional data transmission of sorting system is use of RS485 bus with the advantage of multi-node support, far distance and highly receiving sensitivity. RS485 bus constitutes the network of single master. The equipment mutual communication can be achieved by the master node. Thus th

7、ere are the lower throughput, poor real-time and highly difficulties of communications between slaver nodes. In our work, we introduce RFID technology to replace bar code identification. RFID system is not influenced by dust, humidity, oil, coolant, mining and toxic gases in the production environme

8、nt. Compared with bar code identification, RFID is a contactless technology that allows objects to be scanned and identified without visual or physical 3contact . More importantly, the tag data is not only read by RFID readers, but also can be written time and again. Currently the cost of RFID tag i

9、s gradually reduced, and the tag which ties up with the cigarette box can be reused. It further reduces the cost of system. Furthermore, the traditional RS485 bus is replaced by High-speed CAN bus which provides a multi-master hierarchy, broadcast communication, sophisticated error detecting mechani

10、sms and re-transmission of faulty messages . These feathers allow building intelligent and redundant systems ,which guarantee data integrity and real-time data transmission. With the deployment of RFID middleware and ERP/SCM software platform, the ultimate goal of integration of the tobacco supply c

11、hain logistics enterprise system will be achieved. II. SYSTEM ARCHITECTURE DESIGN There are 50 sorting positions in our system. As a distribution unit, each position corresponds to a cigarette brand. The RF tag is attached to a tray, which has a unique ID to descript some information of cigarette in

12、 details. When the tray moves to a sorting position, RF antenna reads RF tags and collects information to display on LCD. The worker then supplies the cigarettes under the guidance of LCD. The system is composed of the upper machine and lower machine. In upper machine system, MCGS configuration soft

13、ware configures the CANBUS devices, RFID readers and PLC etc. MCGS is a kind of general software for industrial process control and real-time monitoring service, characterized by improved functions, easy to operate and good 5visualization . RFID readers retrieve the information from the RF tag by an

14、tenna array near the conveyer. RFID middleware/driver completes the data processing and sends data to MCGS monitoring platform. ZLG_PCI9810 intelligent CAN card with standard PCI interface, implementing CAN2.0B protocol, establishes the connections with MCGS configuration software by ZOPC_Server (Ba

15、sed on CAN-BUS general OPC Server6) . ZOPC_Server is a kind of OPC server that supports all kinds of ZLG CAN cards. Any client (e.g. KingView, MCGS, Intouch, etc ) that supports OPC protocol can connect ZOPC_Server. It is a bridge that implements the data transmission between CAN card and configuration software. Lower machine system is constituted of CAN intelligent nodes and LCD touch screens. CAN intelligent nodes receive the tag data from CAN bus and display it on LCD. The workers check against and send commands by touching LCD screen. System architecture is shown in Fig.1.
