Abstract-Considering the current problems of low realtime performance for data acquisition and poor monitoring capacity in the production line monitoring system, this paper introduces a production line visual monitoring system, this system introduces the radio frequency identification technology (RFID) into the production line, and realizes the integration of RFID acquisition technology and production line control. This paper presents the system's working principles, architecture and design schemes of the software and hardware, and studies its implementation method and key technologies. The system adopts ARM9 and the embedded Linux operating system to intelligentize the operation terminal, and realizes the display interface more beautiful. The realization of multi-master methods of intelligent nodes via CAN field buses makes the system more stable. Its software and hardware design scheme, key technologies and implementation are presented also. The experimental results demonstrate that the system can be operated steadily and will have a vast application prospect.

One of the most challenging issues in radio frequency identification (RFID) and near field communications (NFC) is to correctly and quickly recognize a number of tag IDs in the reader's field. Unlike the probabilistic anti-collision schemes, a query tree based protocol guarantees to identify all the tags, where the distribution of tag IDs is assumed to be uniform. However, in real implements, the prefix of tag ID is uniquely assigned by the EPCglobal and the remaining part is sequentially given by a company or manufacturer. In this paper, we propose an enhanced M-ary query tree protocol (EMQT), which effectively reduces unnecessary query-response cycles between similar tag IDs using m-bit arbitration and tag expectation. The theoretical analysis and simulation results show that the EMQT significantly outperforms other schemes in terms of identification time, identification efficiency and communications overhead.

“…Although dynamic frame slotting ALOHA calculation method's frame size can be adjusted [8], it does not have a high system efficacy and its design is too complicated. Q calculation method on the other hand, belongs to a type named as heuristic calculation method [9]. It does not need to know the amount of time frames used up and can also adjust the frame size when needed.…”
