Polystar Instruments RFID Test System Receives Dash7 Alliance Approval

December 2010 - Based on NI software and hardware platform, the RFID test system developed by NI System Alliance Shanghai Juxing Instrument Co., Ltd. was independently certified by Dash7 Alliance and third-party laboratory METLab and became the world's first Dash7 Alliance certification. The ISO18000-7 RFID protocol conformance test system is suitable for the protocol conformance testing of RFID tags and readers.

ISO18000-7 is an RFID standard that uses the 433.92MHz carrier frequency band. The ISO18047-7 standard defines its protocol conformance testing method. The Dash7 Alliance is composed of more than 50 companies and related organizations worldwide and is committed to promoting the commercial application of the ISO18000-7 standard. , and guarantee the application of protocol consistency and interoperability support.

Since the RFID reader/tag test is based on the closed-loop mode, real-time communication needs to be completed within a few milliseconds, and the correct timing must be ensured in the communication, which places high demands on the test system. At the same time, RFID protocol conformance testing involves complete physical layer and protocol layer testing. The testing conditions are numerous. For a single parameter, it needs to be tested under different frequencies, different code rates, different coding methods, etc. How to shorten the test time is also a challenge.

Based on the NIPXI modular radio frequency hardware platform and NI LabVIEW, NI TestStand and other softwares, the certified test system of Polystar Instruments can automatically perform tests on more than 50 items of RFID tags and readers. The test system is based entirely on the modular architecture of PXI and fully embodies the technical concept of "software radio." In addition to the up-converter and down-converter, the system also uses an IF transceiver unit with an FPGA to perform on-board signal processing and interactive responses to meet the stringent timing requirements in real-time closed-loop testing. Because the system functions are configured and defined by software, the system can not only perform the protocol conformance and interoperability testing of the ISO18000-7 standard, but also meet the testing requirements of other RFID standards proposed by the ISO or EPC organizations, and can adapt to the future. The development and change of standards.

As a local high-tech enterprise in China, Shanghai Juxing Instrument Co., Ltd. has conducted RFID-related project cooperation with NI since 2005 and has become an alliance provider of NI certification systems. Based on NI's off-the-shelf commercial modular hardware platforms and software tools, PolyStar's engineers can focus on specialized applications that they are good at, reducing system development time and ensuring performance. Relying on years of technology accumulation and long-term support from National Instruments, Polystar Instruments has acquired international competitiveness in RFID testing. Its products are exported to the United States, Japan, Korea, Austria, and Singapore.
