Prototype for Process Control in Residential Environments, Supported by Power Line Communications


Objectives: This article describes the development and implementation of a domotic system communication using as channel domiciliary mains (110 V/60 Hz) to control one or more devices used at home, from the study of the low-proposed stress as a means of data transport. Methodology: The control is performed by software developed in C++ Builder and installed on a PC, using a microcontroller for addressing and two cards PLC 101s-12A for coupling to the line and the FSK modulation for data transmission. Findings: By analyzing the behavior of the system, evaluating the relationship between the behavior of the channel (mains) and data transmitted as well as the cost/benefit ratio to establish the advantages of the prototype to other technologies offered by the current market, it is determined to be a viable proposal to be implemented in households. Applications/Improvements: The system can be used to control devices in residential and industrial environments using the electric network as a physical transmission medium, an aspect that can be considered of great importance when designing and implementing a home automation control solution. For future research work it is suggested the design of prototypes that allow establishing alternative communication processes and coexisting with PLC, in order to generate mechanisms of redundancy and efficiency during the periods of transmission and control of processes.
