Underground CCD photo-communication illumination system

Abstract

The invention discloses an underground CCD photo-communication illumination system. The system comprises a processor module, an LED transmission / reception module, a sensor module, a serial port communication module, a power module, a central processing unit, a reception antenna, a photodetector, a signal processing circuit, a power circuit, a searchlight system, a field programmable gate array circuit and a power circuit, wherein the power circuits are respectively connected with the central processing unit and the field programmable gate array circuit; and each power circuit is internally provided with a solar cell panel, a voltage stabilizing circuit, a power controller and a direct-current power supply circuit. The underground CCD photo-communication illumination system is low in power consumption, has a communication and calculation abilities, is small in volume and low in cost, and can be applied to construction of basement visible light communication networks.

Description

technical field [0001] The invention relates to the field of basement communication, in particular to an underground dedicated CCD optical communication lighting system. 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 and pho...

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
