一种机械式八位二进制密码锁演示仪

A mechanical eight-bit binary password lock demonstration instrument

介绍了一种机械式的具有逻辑功能的密码锁,该密码锁是能直观应用与、或非、异或非等门电路功能的实验装置,它通过单刀双掷开关的开关闭合方向实现门电路的逻辑功能.16个单刀双掷开关构成了8个逻辑单元,构成每个逻辑单元的2个单刀双掷开关向同一方向闭合时,电路导通,否则电路断开.根据实验教学的需要,密码锁装置可以通过设置密码状态实现1～8位密码的破译过程.

Introduces a kind of mechanical password lock with logical function.An experimental device that can be used intuitively to apply the functions of AND gate,NOR gate and XNOR gate.It realizes the logic function of the door circuit through the opening and closing the direction of the single knife double throw switch.There are eight logical units of 16 single-knife double throw switches.When these two single-knife double throw switches close in the same direction,the circuits is connected,otherwise,the circuit is disconnected.According to the needs of experimental teaching,the device can implement the deciphering process of 1~8 bit cipher by setting the password state.
