Description

Controllable ventilation system using power line communication Technical Field The present invention relates to a ventilation apparatus using power line communication, and more particularly, to a system that can control a plurality of ventilation apparatuses through power line communication. The system transmits and receives communication signals through the power line, can control the ventilation device without installing a separate communication wiring, and is applied to a ventilation system capable of effectively managing ventilation in a space. Background In general, large buildings, factories, and buildings having a plurality of independent spaces are all installed with ventilation systems to circulate air. These systems provide a central control to vent each space, which typically continues to operate even if a particular space is empty or unnecessary, which may result in wasted energy. In recent years, a separate ventilation device is installed for each space, and ventilation supply or an automation system is developed by a user to adjust ventilation supply for each space. However, these systems are often difficult to maintain due to the need for separate communication cabling or complex installation, and the operator must directly handle them. The invention provides a ventilation device based on power line communication, which can control a plurality of ventilation devices through a communication mode on a power line so as to solve the problem. This allows the ventilation system to be controlled without separate communication wiring, aiming at improving energy efficiency by achieving fluid air circulation management for each space.
