Embodiment

[0019] In the following embodiments, the wireless forwarding system of the present invention will be described by taking a television set with a built-in transmitting device receiving and forwarding infrared commands to control an air conditioner near the receiving device as an example.

[0020] The infrared receiving head of the TV receives the infrared command sent by the infrared remote control and completes the amplification, detection, shaping and demodulation of the remote control signal to obtain the serial binary remote control coded pulse. After the remote control code pulse is recognized by the main control MCU of the TV, the command code that needs to be forwarded is transmitted to the wireless network processing chip of the radio transmitter. The format is sent to the wireless network card, and after the MAC layer identification control, baseband processing, and DA conversion are completed through the wireless network card, it is modulated to the corresponding radio...

Abstract

The invention relates to a control technique, especially a remote control system for household appliance, disclosing a remote control signal transmitting system and method. And its technical solution comprises transmitting device and receiving device, where the transmitting device comprises infrared receiver and radio transmitter and the receiving device comprises radio receiver and infrared transmitter. And it converts infrared remote control signal into radio remote control signal for transmitting, and finally reduces the radio remote control signal to infrared remote control signal. And its beneficial effects: able to implement remote control of household appliance, increasing remote control distance and convenient to connect with the existing control devices.

Description

technical field [0001] The invention relates to control technology, in particular to a remote control system for household appliances. Background technique [0002] In the short-range remote control of daily household appliances, infrared remote control technology has been widely used as a mature technology. The remote control system is generally composed of a transmitting device (infrared transmitter) and a receiving device (infrared receiver). The control signal uses infrared as a carrier and is transmitted through space. Due to the characteristics of the infrared remote control signal itself, its ability to penetrate obstacles is far from enough, let alone remotely control household appliances in different rooms. For handheld infrared transmitters (remote controls), the emission power of infrared light-emitting diodes is generally relatively small, and the emitted infrared signals are weak. The effective remote control distance and remote control angle are very limited, ...
