Television remote control system

Abstract

The invention provides a television remote control system. The television remote control system comprises a receiving end carrier module, a receiving end signal analysis chip, a voltage control circuit, an electric power carrier module, a central control chip, a transformer, a communication module and a network background. The electric power carrier module and the transformer are connected with power supply input ends of household power. The transformer is connected with the central control chip, reduces the voltage of the household power to 5V and transmits the household power to the central control chip. The central control chip is connected with the electric power carrier module. The television remote control system has the advantages that the installation cost is low, and by only changing and adding existing electric power lines and household electric appliance, the television remote control system can be realized, so that a television does not need to be changed, and the problem of high changing cost is avoided; the transmission of internal control signals is realized in an electric carrier mode, so that communication conflicts are avoided; in addition, user control is realized in a message mode, any people except illiteracies, who can use basic functions of a mobile phone, are capable of well controlling the system, and the difficulty for most middle-aged and aged people to learn to use APPs is effectively avoided.

Description

technical field [0001] The invention relates to a TV remote control system, which belongs to the technical field of smart home. Background technique [0002] In the prior art, for the remote control of the TV, the main method is to pair the user's mobile terminal by connecting to WiFi or Bluetooth, and then the user installs an APP on the mobile terminal to control it. Although this method is relatively easy for a single TV control, but In real life, there are often multiple devices connected to WiFi at the user's home at the same time, and the home network may be at full capacity (for example, the user opens the download software on the computer to download before going out), so the communication control method through WiFi is often not satisfactory. In addition, the user cannot control the remote control through the Bluetooth connection. In addition, in order to achieve remote control, the TV with remote control function is obviously too expensive for the user, and it is d...
