Abstract

The Wireless Sensor Networks for Factory AutomationSensors are used in many devices and systems to provide information on the parameters beingmeasured or to identify the states of control. In recent years, the concept of computer networkinghas gradually migrated into the sensor community and the trend in industry is moving towarddistributed control with intelligent sensing architecture. The rapid development and emergenceof smart sensor and field network technologies have made the networking of smart transducersan economical and attractive solution for a broad range of measurement and control applications.A Wireless sensor network (WSN) has a large number of small, low powered sensor nodes (alsocalled motes), usually densely located in the target area and one or more remote sinks organizedinto a cooperative network. These can be connected to other networks through gateways. Eachnode is equipped with sensing, processing and communication capabilities.Advances in computing and instrumentation, have sparked the need of engineering technologygraduates who can update and improve manufacturing facilities and product design. This paper isan attempt to expose engineering technology students earlier to WSNs and other emergingtechnologies in lieu of taking WSN track in their technology curriculum.In general, it is not economically feasible to build multiple smart sensors systems – one for eachof the currently popular network buses. Recognizing this problem, industry and governmentleaders from the IEEE (Institute of Electrical and Electronics Engineers) actively workedtogether to create a viable standard. The goal of the IEEE 1451 family of standards is to allowthe access of transducer data through a common set of interfaces whether the transducers areconnected to systems or networks via a wired or wireless means.This paper explains in detail the wireless sensor network (WSN) architecture, standards andprotocols. IEEE 1451 is a set of smart transducer interface standards that describe a set of open,common, network-independent communication interfaces for connecting transducers (sensors oractuators) to microprocessors, instrumentation systems, and control/field networks.IEEE 1451.1 defines a common object model and programming paradigm for smart transducersystems. The mission of IEEE 1451.2 was to separate the network issues from the transducerissues. This was accomplished with four concepts: the Smart Transducer Interface Module(STIM), the Network Capable Applications Processor (NCAP), the Transducer IndependentInterface (TII), and the most important element of this strategy the Transducer Electronic DataSheet (TEDS). The TEDS is a memory device attached to the transducer, which stores transduceridentification, calibration, correction data, and manufacturer related information. The STIMhandles the sensor and actuator low-level interface stuff and formats the data communicationmessages between the NCAP and STIM in a standardized digital manner. The NCAP handles thenetwork interface and also manages the TII dedicated interface port to the STIM.This paper will delve into other IEEE 451 standards and discuss how to create WSNs andintelligent interactive devices, and interface with smart sensors and transducers. Networkingactuators and smart sensors and real world technical challenges will also be highlighted.
