  • Publication number: 20100329689
    Abstract: Disclosed are an RF remote-control device is capable of remotely controlling a plurality of pieces of IR equipment and an RF remote control method. A remote-control device upgrades IR remote-control equipment for RF remote control. A “unified” control method remotely-controls a plurality of pieces of IR equipment using one remote controller. An RF remote controller includes a key device, an MCU 1 and its control circuit, and an RF signal module 1. An RF-IR converter comprises an RF signal module 2, an MCU 2 and its control circuit. An IR transmitting circuit is capable of transmitting infrared signals. The RF signal module 1 corresponds to the RF signal module 2, and the IR transmitting circuit corresponds to the IR equipment. The method is realized mainly by the steps: 1) pairing; 2) pre-storing IR code data; 3) placing; and 4) operating.
