智能门禁系统采用凌阳十六位单片机作为系统控制核心，利用其强大的语音识别功能，不仅实现了语音播放功能，完成了语音提示的要求，而且实现了语音控制门禁系统；利用其内置的Flash闪存，实现了密码的断电保护。除此而外，在键盘输入方面，强大的功能选择键满足了系统的要求；16*2液晶显示器的选择使操作要求清晰明了。此套智能门禁系统强烈体现了其人性化的一面-Intelligent access control system uses the Sunplus 16 single-chip system control as the core, to use its powerful voice recognition features, not only realize the voice playback, the voice prompts to complete the requirements, but also realize the voice control of access control systems the use of its Purchase of Flash memory, realize the power to protect your password. Furthermore, in keyboard input, the choice of powerful features to meet key requirements of the system 16* 2 LCD display options so that operating requirements clear. This set of intelligent access control system strongly reflects its human side
