Design of IEEE1451.5 WTIM for Industrial Network Based on Ubiquitous Sensor Network

Recently,the use of ubiquitous sensor network technology has spread vastly.The ubiquitous sensor networks are widely deployed in factory automation as they provide effective measuring solution for instruments.The wired/wireless network module,which provides the interface to connect to the u-sensor network,is needed but there is no perfect standardization about the interface.In this situation,the interface compatibility between measuring instrument can he maintained using the IEEE1451 international standard.In this paper,the Wireless Transducer Interface Module(WTIM)based on IEEE1451.5 was designed.It connects to the measuring instnment,like the multi-meter,power meter,and etc.,to suppot the RS232 interface.As these devices cannot connect to network without a module,we use the WTIM to help these devices connect to network system.Its function was verified through the ubiquitous network connection and data transfer between monitoring PC and measuring instrument.This technology is expected to reduce cost in order to construct the wireless industry autonntion system using existing devices.
