Embodiment Construction

[0063] An RF communication system 1 according to an embodiment of the present invention will be described below using FIGS. 1 to 10 . FIG. 1 is a block diagram showing configurations of a remote control transmitter 3 on the transmitting side of an RF signal and a controlled device 4 on the receiving side of an RF communication system 1 . In this embodiment, the RF communication module 2 having the same configuration as shown in FIG. 2 is used in each of the remote control transmitter 3 and the controlled device 4 .

[0064] In the RF communication module 2, on one side of the printed wiring board 6, a printed antenna 7 formed by a printed wiring conductive pattern, a control MPU serving as a communication control unit 8 mounted on the remaining mounting surface, and an RF communication The RF communication of the circuit section 9 is constituted by an IC chip. The printed wiring board 6 is formed by printing the wiring printed antenna 7 on the wiring board 6 of high permittiv...

Abstract

The object of the present invention is to provide an RF communication system that can pair a group of remote control transmitters and controlled devices without pairing each controlled device with a remote control transmitter and without imposing a burden on the user side. Make a pair. When the operator first uses the remote control transmitter to control the controlled device with a specific action, the remote control transmitter sends RF packet data including the main ID and control data and the status code indicating the start of pairing through the RF signal, and receives the RF signal. The controlled device sends back RF packet data including the slave ID and master ID and a status code indicating pair ACK to the remote control transmitter by RF signal, and at the same time, performs The act of controlling the data, in the process of remotely controlling the controlled device, the operator performs the pairing process unconsciously.

Description

technical field [0001] The present invention relates to an RF communication system for remotely controlling a controlled device with an RF signal sent from a remote control transmitter, and more specifically, to an RF communication system for a remote control transmitter and a controlled device that determine a pair to send and receive RF signals. Background technique [0002] In the remote control of home appliances such as air conditioners and televisions, infrared communication (IR communication) is generally used to transmit infrared control signals (IR signals) of infrared rays (Infrared Rays) including control data from a remote control transmitter to these home appliances. However, in recent years, attention has been paid to radio communication (RF communication) systems that carry control data using RF (Radio Frequency) signals that can be transmitted even if there is an obstruction in the middle, and the transmission direction is not restricted. [0003] In the RF c...
