Festive lantern driving system based on PLC-BUS technology

Abstract

The invention provides a festive lantern driving system based on PLC-BUS technology. One end of a power distributor is connected to the mains supply, and the other end of the power distributor is connected to a PLC circuit to supply power; the PLC circuit is connected to one end of a PLC gateway, one end of a control panel and one end of a voice recognition chip so as to achieve the transmission of PLC-BUS power carrier signals. The PWM circuit is connected to the other end of the PLC gateway and the other end of the control panel and connected to a main control chip, and the main control chipis connected with the voice recognition chip and the control panel so that the main control chip, the voice recognition chip and the control panel can transmit control signals. The voice recognitionchip is connected with a voice acquisition circuit so as to receive a voice signal output by a user; the PWM circuit is further connected to an LED electric lamp, a wavelength analysis chip is arranged in the LED electric lamp, and the wavelength analysis chip is connected with an acquisition assembly arranged outside the LED electric lamp so as to reduce the influence of ambient light on the light color of the LED electric lamp.

Description

technical field [0001] This application relates to the technical field of the Internet of Things (IOT), in particular to a lantern driving system based on PLC-BUS technology. Background technique [0002] PLC-BUS technology (PulsePositionModulation (PPM)) is a new power carrier communication technology developed in recent years, referred to as pulse phase modulation method. It uses the sine wave of the power line as a synchronous signal, and sends instantaneous electrical pulses in four fixed timings to transmit signals; PLC-BUS signals can be transmitted very far, and PLC-BUS signals can be transmitted in an office environment without any electrical appliances. Each floor is about 1000 square meters, which can be easily transferred to any corner of the 30 floors. In the office environment with electrical appliances installed, each floor is about 1,000 square meters, which can be easily transferred to any corner of the 15 floors. Due to the particularity of the PPM communi...

Problems solved by technology

[0004] However, the current intelligent lighting system generally has a lantern structure on the smart lamp, which is used to make the lamp emit various colors, but the smart lamp does not have the function of voice-activated color adjustment, and the corresponding adjustment is generally carried out through the panel. Color adjustment. In addition, the existing smart lights do not adjust well in combination with the surrounding environment, but only clumsily perform relevant color changes according to the instructions input by the user through the panel, which often fails to achieve the desired effect of the user.
