Mobile-phone-terminal solar LED light-control door access device

Abstract

The invention discloses a mobile-phone-terminal solar LED light-control door access device. The mobile-phone-terminal solar LED light-control door access device comprises a visible light transmission link, a master controller, an audio encoding-decoding device and an audio input-output end, wherein the visible light transmission link comprises an LED drive circuit, an LED lamp, a lens, a PD light-sensitive tube and a photoelectric detection module; the master controller is a single-chip microcomputer and used for controlling the audio encoding-decoding device to collect voice data and perform compression encoding and transmitting the collected data to the LED drive circuit through a serial port, and the LED drive circuit transmits an on-off signal according to instruction; the photoelectric detection module controls the PD light-sensitive tube to receive a light signal and transmits the same to the master controller, and the master controller transmits the received data to audio encoding-decoding device for decoding and outputting. The mobile-phone-terminal solar LED light-control door access device is low in complexity and cost, long in communication distance, capable of achieving both lighting and real-time voice communication, and capable of transmitting data other than voices.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to a solar LED light-controlled access control device for a mobile terminal of a mobile phone. Background technique [0002] Solar energy (solar energy) refers to the thermal radiation energy of the sun (see the three ways of thermal energy transmission), and its main manifestation is the sun's rays that are often said. In modern times, it is generally used to generate electricity or provide energy for water heaters. Since the birth of life on earth, it has mainly survived on the heat radiation energy provided by the sun. Since ancient times, humans have also known to use sunlight to dry objects and use it as a method of making food, such as making salt and drying salted fish. With fossil fuels decreasing day by day, solar energy has become an important part of the energy used by human beings and has been continuously developed. There are two ways to use solar energy...
