Integrated sensor RFID (radio frequency identification device) system and mixed-mode interface performance test method thereof

Abstract

The invention discloses an integrated sensor RFID (radio frequency identification device) system and a mixed-mode interface performance test method thereof. The method comprises the following steps of: connecting a logical analysis set to the mixed-mode interface of the integrated sensor RFID system, wherein the logical analysis set comprises an LA_Probe_E measurement line, an LA6000 logical analyzer and a host, an interface transmission signal goes through the measurement line, the logical analyzer and the host, and is decoded by upper computer software to obtain the characteristics of the interface transmission signal; checking with a signal transmission protocol to obtain the plug-and-play performance parameters of the mixed-mode interface; performing electrostatic discharge destructive test on a host interface and a sensor module interface on a mixed-mode interface bus respectively; and re-detecting the quality of independent communication and joint communication by using a plug-and-play validity test method to obtain an estimation result of the hot-plug performance of the mixed-mode interface. The performance indexes of the mixed-mode interface tested by the method mainly include plug-and-play speed, plug-and-play success rate and hot-plug success rate; and the plug-and-play validity and reliability of the mixed-mode interface can be monitored through the performance indexes, thereby conforming to the interface performance test requirements required by the development trend of the integrated intelligent sensor RFID system.
