Radiofrequency identification detection system

The utility model provides a radiofrequency identification detection system, which relates to the technical field of radiofrequency identification and aims to solve problems that radiofrequency identification testing systems in the prior art are complex in structure and high in cost. The radiofrequency identification detection system comprises a computer, monitoring equipment, an antenna, a control unit, an adjustable modulator, an adjustable power amplifier, a reader-writer signaling unit and an electronic tag simulator, wherein the reader-writer signaling unit and the electronic tag simulator respectively simulate actual working actions of a reader-writer and an electronic tag, and send results and monitored data to the computer to detect the to-be-detected electronic tag and the to-be-detected reader-writer. Test precision can be increased by aid of the adjustable modulator, the adjustable power amplifier and the high-performance monitoring equipment; costs for reader-writer simulators and the electronic tag simulators at the same frequency range with different protocols can be saved by aid of soft ware configuration; and hardware expansion to FRID tests with different protocols and frequency ranges can be realized by aid of a user-defined bus type slot structure.
