Embodiment Construction

[0010] According to the structure diagram of the present invention ( figure 1 ), making an intelligent projector based on power carrier technology, capacitor selection (0.22μF / 400V), transformer selection (1:1), output signal power amplifier (dual MOS tube), and external crystal oscillator (24mhz) for the oscillator ,

[0011] When in use, the projector is connected to the electrical circuit, and the leads are connected to the 220V power line. The projector is connected to the network through the Internet of Things bridge on the power line, and then connected to the computer or mobile phone at the other end of the network through the network server. Computer or mobile phone can remotely control the projector, such as figure 2 As shown, the computer or mobile phone sends a signal (including the address code), which is sent to the server through the network. After being processed by the software in the server, it is transmitted to the Internet of Things bridge, and then trans...

Abstract

Along with continuous development of the artificial intelligence technology, more and more remote control requirements are needed, and communication of control signals becomes an important part of the artificial intelligence technology. The adoption of power line carrier communication is undoubtedly the most economical method. The invention applies the principle and the method being completely different from traditional power line carrier communication, obtains the technical breakthrough of the power line carrier communication on a 380V / 220V low-voltage power grid, and realizes the transmission of communication signals in a high-noise environment. The invention discloses a remote intelligent projector technology in the carrier wave technology. The projector is accessed to a network through an Internet of Things bridge on a power line and then is connected with a computer or a mobile phone at the other end of the network through a network server, and the computer or the mobile phone can remotely control the projector.

Description

technical field [0001] The invention relates to the field of intelligent electric appliances. It is a technology that uses power line carrier technology for remote control. Background technique [0002] With the continuous development of artificial intelligence technology, the demand for remote control is increasing, and the communication of control signals has become an important part of artificial intelligence technology. It is undoubtedly the most economical method to directly transmit control signals through power lines. This method is called power line carrier communication. [0003] Power line carrier communication technology appeared in the early 1920s. The technology of carrier communication on transmission lines with voltage levels above 10kV is quite mature. However, the power carrier communication on the 380V / 220V low-voltage grid has not been ideal. Especially in recent years, due to too many devices on board and too much noise and interference on the power ...
