In the embodiment of the present invention, the remote control software updating unit is installed in the smart phone 11 in an uninstallable manner, so that the remote control software updating unit can be updated in time through a network, and a user can download the latest remote control software corresponding to a target electrical product. And the downloaded remote control software is stored in the storage unit 115, so that the user does not need to download again when remotely controlling the same target electrical appliance next time. Of course, considering that the remote control software occupies the storage space of the smartphone 11, the remote control software may also be deleted after the remote control software is used.
In the embodiment of the present invention, the infrared emitter 12 and the smartphone 11 are independent from each other. And the infrared emitter 12 can be miniaturized and can be purchased separately. In practical use, the universal remote control system of the present invention can be formed by electrically connecting the earphone plug of the audio receiving unit 121 of the infrared transmitter 12 with the earphone jack of the audio output unit 116 of the smartphone 11. Therefore, a user can conveniently complete remote control of various electrical appliances around the user only by carrying the smart phone 11 and the small infrared emitter 12, and does not need to equip each electrical appliance with a specific handheld remote controller. Therefore, the universal remote control system can reduce the resource waste caused by one-to-one correspondence of the electric appliance and the handheld remote controller.
