Preferably, control centre 2 also includes, when user is for active stage, sending and changing sleep cycle order extremely Forwarding unit 3;Forwarding unit 3 also includes receiving and perform to change sleep cycle order, shortens sleep cycle.
Control centre 2 of the present invention, according to user's service condition, is automatically adjusted the length of one's sleep of forwarding equipment 3, Make forwarding unit 3 neither affect Consumer's Experience, can guarantee that again the life-span.
The specific works process of a kind of infrared remote control system of the present invention is described with instantiation below, as follows:
First the pairing of paired device 5 and controlled device 4 is carried out.
Paired device 5 sends unpaired message to forwarding unit 3;
Forwarding unit 3 receives unpaired message, at central processing module 32 by infrared receiving module 34 Reason unpaired message, then sent to control centre 2 by wireless communication module 31;
Control centre 2 resolves unpaired message, automatically identifies the controlled device 4 mated with unpaired message, for Family provides the list of all possible controlled device 4, and user selects the controlled device 4 needing to control, and completes to join Right.
2. remote control equipment 1 controls controlled device 4.
Remote control equipment 1 sends control information to control centre 2;
Control centre 2 receives and conversion controling information generates infrared coding information, sends infrared coding information extremely Forwarding unit 3;
Forwarding unit 3 receives infrared coding information by wireless communication module 31, and processes mould by central authorities Block 32 extracts the infrared code order of infrared coding information acquisition, sends infrared code by infrared transmission module 33 and orders Order is to controlled device 4;
Controlled device 4 receives and performs infrared code order.
Additionally, the present invention is after user enters active stage, adjust the state of forwarding unit 3 according to service condition, Make forwarding unit 3 frequently enter wake-up states, reduce time delay.Specific works process is as follows:
After networking success, forwarding unit 3 periodically enters sleep and wake-up states.
In each wake-up states, and control centre 2 carries out data exchange, informs that control centre 2 forwards and sets Standby 3 current states.
After control centre 2 detects that user enters active phase, inform that forwarding unit 3 changes sleep cycle.
Control centre 2 is next order turn at the wake-up states of next forwarding unit 3 after receiving user command Issue forwarding unit 3.
The present invention solves the limited transmission range with infrared signal of existing infrared forward gateway technology, as every The difficult problem that wall i.e. cannot transmit, and it is inadequate to coordinate transponder computing capability by control centre 2, it is impossible to real The problem now mated with household electrical appliance.In order to reach the function of power saving, the present invention is changed by control centre 2 The sleep cycle of forwarding unit 3, makes forwarding unit 3 frequently be in wake-up states, reduce operation delay and Reduce and power consumption is affected.
