Design Of The Embedded Entrance Guard System Based On Hi3518E

Along with the increase of today’s technology and people’s awareness of security, Entrance Guard systems used in modern office and people’s lives are showing more and more widely, For the realization of the Entrance Guard area of intelligent management, the thesis design an embedded Entrance Guard system based on a system-on-chip.The thesis briefly describes the characteristics and technology status of Entrance Guard system. the embedded Entrance Guard system was designed based on chip Hi3518 E, including Hi3518 E circuit, video image collection circuit, audio capture and playback circuit, electric locks control circuit and serial level conversion circuit; briefly design the software of embedded Entrance Guard based on Linux development environment, including system drive program,media platform MPP system control program, video capture and coding program, audio coding and compression capture circuit control program. Finally, the Entrance Guard systems designed by thesis was tested and the results shows that the Entrance Guard system meet the requirements of user.
