系统由单片机、显示器等部分组成，利用显示器来显示密码锁输入的相关信息，密码输入正确则打开密码锁通过PM函数产生而为PM随机海面，产生模拟海面，进而进行计算模拟(The system is made up of single-chip microcomputer, display and other parts. It displays relevant information of the password lock using the display. If the password is entered correctly, the password lock is generated by the PM function and the PM random sea surface. The simulated sea surface is generated, and then the simulation is carried out.)
