Abstract

The invention discloses an entry-exit remote light control system which comprises a light key module, a light control lock module, a central processor, a field-programmable gate array circuit and a power circuit. The power circuit is connected with the central processor and the field-programmable gate array circuit. A solar cell panel, a voltage stabilizing circuit, a power controller and a direct current supply circuit are arranged inside the power circuit. Unlocking passwords are sent out through a light key, code information is loaded on an LED lamp of the light key, information is transmitted to a light detection module of a light control lock through a free space, and opening and closing of a door lock are controlled through comparison information. The system saves energy, and is environmentally friendly, high in safety and capable of being widely applied to application occasions such as hotels, office buildings and the like.

Description

technical field [0001] The invention relates to the technical field of visible light communication, in particular to an entry-exit long-distance optical control system. Background technique [0002] As we all know, the access control system is a system for managing entrances and exits. [0003] 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...
