The Practical Design of Constructing Data Transition Interface with ZigBee WSN and RS-485 Wired Interface - Example with Small-scaled Wind-power Electricity Generator System

─The purpose of this study was to explore the related practical techniques of monitoring and controlling system in designing renewable energy system, especially for Small-scaled wind-power generator. Recently, the whole world was actively developing replaced energy to solve the economic development and daily-life necessities problems resulting from gradually lacking of oil. Taiwan government was progressively planning to develop small-scaled wind-power generators under authority of Energy Bureau of Economy Minister. The real-time running parameters of wind-power generator is very essential for designing the power-generating system, in this paper, a data transition system including how to construct ZigBee NonBeacon-Enable-Network, communication techniques, data coding, and its interface for collecting running parameters in wind-power generator was designed with both ZigBee wireless-sensor-networks (WSN) module and wired RS-422 Interface to double check the precision of transmitting data. The final result of this study has successfully implemented in a practical small-scaled wind-power generator system which was part of integrated-project of Teaching Superior Projects authorized by Taiwan Education Minister –Constructing Monitoring and Controlling Interface in Small-scaled Wind-power Generator System, and the validity and stability of the system has been proved efficient and successful.
