Abstract
In recent years, with the continuous development of Visible Light Communication (VLC), its application fields are constantly expanding. In view of the tradition various gating locks have some shortcomings, especially in terms of safety needs to be improved. The visible light communication technology and access control system are joined to design a Hamming-encoded visible light communication access control system in this paper. The hardware design of this access control system is given in this paper and the system of Hamming coding is analyzed. Through MATLAB software simulation, the results show that the access control system with Hamming code can effectively reduce the bit error rate, and can provide about 2 dB coding gain. In the experiment, the system works well just like simulation. Hamming code greatly improves the performance and safety of the visible light communication access control system.
