实现了RGB空间转换到HSI空间，并分别求出S分量（饱和度）、I分量（亮度、光强）-Implements the RGB space to HSI space, and respectively calculate S components (saturation), I (brightness, light intensity)

系统由单片机、显示器、键盘等部分组成，利用显示器来显示密码锁输入的相关信息，系统上电时内部默认两组数字密码（4位或4位以上）；设置其他另外密码，或进行密码校验，密码输入正确则模拟打开密码锁(The system is composed of MCU, LCD, keyboard and other components, using the display to display information related to input password lock, when power on i
