Control Management System for Air Conditioner via Power Line Communication Modem - PLC

With several technological initiatives developed with the PLC modem (Power Line Communication), among the most varied themes developed regarding the relationship from the characteristics of the electric distribution networks, the study in transmitting data through the electric network is to show that it is possible to transmit the data in a fast, reliable and safe way through the electric circuit well structured, thus adjusting the connections between the profit, the reduction of costs and the conservation of preventive maintenance, mainly in what concerns the reuse of electric network in already structured places. However, in addition to implementing control management, we have identified some reasons that have not made it possible on a large scale as an alternative for transmission with regard to interference and noise and how we pointed out solutions to this problem. Thus, we addressed technical characteristics between equipment, circuit structure, multiplexing, frequency, technical comparisons with other data transmission technologies and an overview of the market, evaluating and showing that this technology has the potential to enable the communication of data in low-voltage electricity networks to serve the specific school, meeting the requirements for protocol transfer, especially for monitoring applications, and rapid response. The explanations about definitions, advantages, disadvantages, requirements, the interfaces of the electrical system and other arguments, are portrayed in a didactic and simple way, in order to facilitate the understanding of this technology.
