Photovoltaic energy-saving intelligent communication flashlight

Abstract

The invention discloses a photovoltaic energy-saving intelligent communication flashlight, which comprises a receiving antenna, a signal processing circuit, a power circuit, and a white-light LED (Light-emitting Diode). The intelligent flashlight is a single-chip microcomputer and is used for controlling an audio coder-decoder to collect and compressed-code voice data, and sending collected data to an LED drive circuit through a serial port; the LED drive circuit sends an on-off signal according to an instruction; a photoelectricity detection module controls a PD photosensitive tube to receive a photosignal and conveys the photosignal to the intelligent flashlight; and the intelligent flashlight sends the received data to the audio coder-decoder so as to decode and output. The system realizes low complexity and cost, far communication distance, and capability of taking into account both illumination and real-time voice intercom; and meanwhile, the system can be used for transmitting other data besides voice.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to a photovoltaic energy-saving intelligent communication flashlight. 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: photothermal conversion...

Problems solved by technology

In the prior art, the realization of communication must still depend on the communication network. If the signal of the wireless communication network is relatively weak or there is no signal of the communication network when traveling in the deep mountains, the friends who are far away (for example, a friend who is alone or lost and teams) cannot get in touch through the communication network

The transmission of information through the communication network brings convenience to people's lives, but its application still has limitations.

Moreover, communication using a communication network requires payment of fees to the operator of the communication network

In particular, the use of communication networks for communication within a short distance increases the cost of communication

At the same time, the current lighting device using LED is only used for lighting and has a single function, so a flashlight based on visible light is needed to realize the function of lighting and the purpose of communication
