摘要：

In order to improve the self-recognition capability of the IEEE 1451 smart sensor and enhance the level of sensor's intelligence and application flexibility, this paper presents a SPWD (sorting pulse width difference) based IEEE 1451.2 smart sensor self-recognition mechanism. The mechanism realizes baud rate self-adaption of IEEE 1451.2 serial interface first adopting the SPWD method. It also utilizes TEDS (transducer electronic data sheet) definition and configuration technique and virtual TEDS parsing algorithm to achieve smart sensor self-recognition. Then, an IEEE 1451 smart weighing sensor system is constructed using this mechanism and its self-recognition properties are tested. The experiment results show that, when the baud rate is 28800 bit/s, SPWD based IEEE 1451.2 smart sensor's recognition rate is 99.07% and its average recognition time is 1.20s.
