Abstract-The purpose of this project is for effective elevator control system， which can be reprogrammed in a fashion to minimize the congestion on a particular lane by directing the lift on a particular floor using time management Present scope of the project is to provide an automatic congestion 摘要——本计划旨在设计一种电梯有效控制系统，该系统通过重组方式使特定通道的拥塞最小化，即利用时间管理方案控制电梯停留在特定楼层。目前该计划范围是提供一种自动拥塞控制。
In cryptography teaching process， classical password is based， so all cryptography to grasp classical password is particularly important Based on the classical password difficult in the process of teaching， from the viewpoint of teaching， developed a simple understandable cryptography teaching demonstration software respectively， the three classical password - shift password， single table substitution code and replace the password - encrypt &decrypt The three password encryption process of single-step demo; For decryption process， shift password using exhaustively law cracked， single table substitution code and replace the password using statistics Through this software， learners can well master three classical password encryption and decryption 看看吧 不知道对不对
