智能手机用作电视机遥控器的设计

文章讨论了用Wi-Fi转TTL电路替代电视机红外接收电路,在智能手机中增加Wi-Fi控制电视机的应用程序,使电视机具有被智能手机Wi-Fi控制的功能。文中给出了Wi-Fi转TTL的电路,智能手机应用程序设计方法和程序框图。本文还讨论了智能手机通过Wi-Fi对家中多台电视机遥控的方法,以及如何应对空中一般性的电磁干扰,为减少家庭中红外遥控器的种类和数量提供了一种方法。

Design of Using Smart Phone as the Remote Controller for TV Set

This paper discusses the use of the Wi-Fi converted TTL circuit to replace the mtrarea receiving circuit of the TV. After introducing application into the smart phone, the TV could be controlled by the smart phone via Wi-Fi. The Wi-Fi converted TTL circuit, the design method and the program flow chart of the smart phone application are also given in this paper. This paper also discusses the remote control method to control multiple TV sets by the smart phone via Wi-Fi, and the methods to deal with general EMI existing in air, so as to reduce the kinds and amount of the infrared remote controler in the family.
