Embodiment Construction
[0025] See figure 1 , figure 1 It is a structural schematic diagram of the first embodiment of the universal remote control system of the present invention. Such as figure 1 As shown, the universal remote control system of the present invention includes a smart phone 11 and an infrared transmitter 12 .
[0026] In this embodiment, the smart phone 11 is used to download and start the target electrical appliance (such as figure 1 The remote control software of the TV shown in ) generates a remote control interface, and the smart phone 11 is further used to process the remote control information input by the user, and obtain the key information corresponding to the remote control information according to the processing result, and then use the key information to modulate a specific low The audio carrier signal then generates an audio modulation signal, and then transmits the high frequency part of the audio modulation signal to the left channel of the audio output unit, and tr...

The invention relates to the field of a remote control technology, and specially relates to a universal remote control system. The universal remote control system comprises the following components: an intelligent mobile phone which is used for downloading and controlling the remote control software of a target electric appliance and is further used for processing remote control information input by a user to generate an audio modulation signal, accordingly transmitting the high-frequency portion of the audio modulation signal to the left sound channel of an audio output unit and transmitting the low-frequency portion of the audio modulation signal to the right sound channel of the audio output unit; and an infrared emitter which is used for converting a received low-frequency audio signal to a power signal so as to drive an infrared emitter to work normally and is used for processing a received high-frequency audio signal to generate an infrared ray modulation signal so as to remotely control the target electric appliance. By such a mode, the universal remote control system has the following advantages: the structure is simple, battery replacement of the infrared emitter is unnecessary, the use is convenient, and the resource waste problem can be reduced that electric appliances are each equipped with one hand-held remote controller.
Description
technical field [0001] The invention relates to the technical field of electrical remote control, in particular to a universal remote control system. Background technique [0002] Most of the current hand-held remote controllers correspond to the controlled appliances one by one, so that a family often needs to purchase multiple hand-held remote controllers, and various hand-held remote controllers cannot be used universally, resulting in a waste of resources. In addition, the hand-held remote control integrated with many remote control software for electrical appliances cannot update the remote control software of the target electrical appliances in real time through the Internet (Internet), which limits the scope of use of the hand-held remote control. [0003] Therefore it is necessary to provide a universal remote control system to solve the above technical problems. Contents of the invention [0004] The present invention provides a universal remote control system. T...
