Abstract

Disclosed is an automatic control system using a power line communication method. The automatic control system comprises an operating module having an operating program; a power line communication module connected to the operating module; and an automatic control module connected to the power line communication module through a power line and adapted to control external appliances by means of a control signal supplied thereto from the operating module. The operating module receives and processes a signal from external appliances through the automatic control module, or generate an appliance control signal for transmission to the automatic control module, thereby implementing a low-speed power line communication together with the automatic control module through the power line communication module. The automatic control system may remotely control or monitor various electric appliances through an Internet network using a conventional power line.

Claims

1. An automatic control system using a power line communication method, comprising:

an operating module having an operating program installed therein;

a power line communication module connected to the operating module; and

an automatic control module connected to the power line communication module through a power line and adapted to control external appliances by means of a control signal supplied thereto from the operating module, the automatic control module including

a power line communication section connected to the power line communication module through the power line and adapted to transmit and receive a signal to and from the power line communication module,

a controller adapted to analyze the control signal supplied from the operating module through the power line communication section to divide the control signal into a switching signal, an analog signal and an infrared ray signal or adapted to convert a signal applied from the external appliances for transmission,

a relay output section adapted to receive the divided switching signal from the controller to transmit the received switching signal to the external appliances,

a PWM output section adapted to receive the divided analog signal from the controller to transmit the received analog signal to the external appliances,

an infrared ray signal output section adapted to receive the divided infrared ray signal from the controller to transmit the received infrared ray signal to the external appliances,

a digital signal input section adapted to receive a digital signal from the external appliances, and

an analog signal input section adapted to receive an analog signal from the external appliances,

the operating module being adapted to receive and process the converted signal from the controller of the automatic control module, or generate an appliance control signal for transmission to the automatic control module, thereby implementing a lowspeed power line communication together with the automatic control module through the power line communication module.

2. The automatic control system according to claim 1, wherein the automatic control module further includes a memory adapted to store the control signal for controlling the external appliances therein so that the stored control signal controls the external appliances.

3. The automatic control system according to claim 1, wherein an Internet terminal connected to the operating module through an Internet network remotely controls the external appliances.
