[Software Engineering] RFIDANDCONTAINER DL : 0: 硕士论文，设计了基于RFID的集装箱电子锁并讨论了电子标签的防碰撞机制。比较了目前常用的电子标签常用的防碰撞方法。在Aloha算法和时间片Aloha算法的基础上加以改进，可自动获取读头读取范围的标签ID清单并动态分配时间片给电子标签。在该算法中融入系统低频唤醒和定时唤醒的特点，以降低电子标签的功耗。-Master' s thesis, the design of container-based RFID electronic lock and discussed the e-tag anti-collision mechanism. Comparison of the current commonly used electronic tags commonly used anti-collision method. In the Aloha algorithm and time slot based on the Aloha algorithm to be improved, can automatically obtain the reader to read the label ID range list and dynamic allocation of time slices to the electronic tag. In the algorithm integrated into the system wake-up frequency and timing characteristics of wake-up in order to reduce the power consumption of electronic tags.

[Software Engineering] CODED-LOCK DL : 0: 密码锁设计一个密码锁，平时处于等待状态。管理员可以设置或更该密码。如果不预置密码，密码缺省为“999999”。用户如果需要开锁，按相应的按键进入输入密码状态，输入6位密码，按下确定键后，若密码正确，锁打开，若密码错误，将提示密码错误，要求重新输入，三次输入都错误，将发出报警信号。报警后，只有管理员作相应的处理才能停止报警。用户输入密码时，若输入错误，在按下确定键之前，可以通过按取消键重新输入。正确开锁后，用户处理完毕后，按下确定键，系统回到等待状态。系统操作过程中，只要密码锁没有打开，如果60秒没有对系统操作，系统回到等待状态。注意：输入按键信号时必须一个按键一个按键输入，不得6个按键一起输入。-Design a password lock password lock, usually in a wait state. Administrators can set or the password. If no preset password, the default password is " 999999." If users need to unlock, press the corresponding button to enter the state to enter a password, enter the six-digit password and press the OK key, if the password is correct, the lock is open, if the password is incorrect, the password error prompt asking to re-enter, three inputs are wrong, The alarm signal. After the alarm, only the administrator for the appropriate treatment to stop the alarm. When the user enters a password, if you enter the wrong, before pressing the OK button, you can press the Cancel button to re-enter. After unlocking correctly, the user is processed, press the OK button, the system returns to the wait state. During system operation, as long as the lock is not open, if 60 seconds is no operating system, the system returns to the wait state. Note: When you enter a key signal must be a key input
