Abstract
The invention provides a method for preventing mutual interference of signals of a remote controller and infrared forwarding equipment. The infrared forwarding equipment is used for converting a control signal transmitted by a television set into a corresponding infrared signal and forwarding the infrared signal to another controlled device. When the infrared forwarding equipment receives an infrared signal transmitted by the remote controller of the television set and needs to forward an infrared signal with the same carrier wave frequency as that of the infrared signal of the remote controller of the television set at the same time, a delay of T time needs to be performed on the infrared signal to be forwarded, so the controlled device will not receive two infrared signals with the same carrier wave frequency simultaneously at the same time point, and therefore mutual interference of signals is avoided.

Embodiment
As shown in Figure 2, be the system module schematic diagram of the television set forwarding infrared remote-controlled signal of one embodiment of the invention.Television set (TV) comprises TV infrared receiving module, TV SOC, WIFI module.TV infrared receiving module accepts module for receiving the signal of TV remote controller, and WIFI module is used for being connected with cloud server by router or being wirelessly connected with infrared transceiver module.Infrared forwarding unit is used for forwarding television set control signal to other controlled plant (Set Top Box, air-conditioning, fan etc.).Infrared forwarding unit comprises infrared receiving module, infrared transmission module and infrared control module, described infrared control module is used for the control signal of television set to be converted to the infrared signal that will launch, launched by described infrared transmission module, when the infrared signal that described infrared forwarding unit receives TV remote controller is with when will forward identical with the infrared signal carrier frequency of a TV remote controller infrared signal simultaneously, the infrared signal that will forward is done to the time delay of a T time, the infrared signal simultaneously receiving two same carrier frequencies can not be put at one time to make controlled plant.Described infrared forwarding unit can carry out omnidirectional's angular emission infrared signal.Described infrared receiving module and described infrared transmission module are all the infrared module of full rate.
Below with television set to the control of Set Top Box for example illustrates the present invention.
After TV remote controller starts APK program by operation push-button operation television set, television set can by the WIFI module carried, cloud server is connected to by wireless router, transfer the code value for Set Top Box and corresponding carrier information, return to TV SOC, pass to infrared forwarding unit by television set by the mode (as usb protocol) of wired connection, together with finally code value and carrier wave being loaded by infrared forwarding unit, launch controller top box by infrared forwarding unit.
As shown in Figure 3, infrared forwarding unit is as follows to television set control signal forwarding process:
Infrared forwarding unit judges that whether the carrier wave of the infrared signal that the remote controller of television set sends is identical with the carrier frequency of the Set Top Box that finally will control;
When the carrier wave of the infrared signal that TV remote controller sends is different with the carrier frequency of the Set Top Box that finally will control, the signal that infrared forwarding unit is launched is transmitted directly to Set Top Box, the infrared signal that the infrared signal that TV remote controller sends can not disturb infrared forwarding unit to send.
When the carrier wave of the infrared signal that TV remote controller sends is identical with the carrier frequency of the Set Top Box that finally will control, infrared forwarding unit does the time delay of a T time to the infrared signal that will forward, to make Set Top Box can not put the infrared signal receiving two same carrier frequencies at one time simultaneously, thus avoid the mutual interference problem of signal.
As shown in Figure 4, in an alternative embodiment of the invention, the infrared forwarding unit in Fig. 2 is built in television set, thus television set can be made directly to have the function of infrared forwarding.
Compared with prior art, method of the present invention is when the signal of the infrared signal that infrared forwarding unit receives TV remote controller and the same carrier frequencies that transmitted by TV simultaneously, signal for TV transmission does the time delay of a T time, guarantee controlled plant point at one time, the infrared signal of two same carrier frequencies can not be received simultaneously, thus avoid the mutual interference problem of signal.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, all should be considered as belonging to protection scope of the present invention.
