基于PLC的电子密码锁的设计与实现

Design and Implementation of Electronic Cipher Lock Based on PLC

随着PLC技术的发展,将其应用于密码锁装置的控制中,取代原有传统锁,取得了很好的使用效果。电子密码锁具有操作快、修改密码比较简单随意、只需输入0~9数字即可开锁、保密性好、编码量多等优点,远远大于弹子锁。随机开锁成功率几乎为零。文章设计了一种以PLC为控制器、结合触摸屏技术的密码锁,可用于工厂、水电厂等工业控制领域。

With the development of PLC technology, it is applied to the control of the password lock device, replacing the traditional lock, and achieved good results. Electronic cipher lock with fast operation, modify the password is relatively simple casual, only need to input 0 - 9 digital can unlock it, good secrecy, coding, etc., far greater than the spring lock. Random unlock success rate is almost zero. In this paper, a PLC controller is designed, which is based on the combination of the touch screen technology. It can be used in the industrial control fields such as factories, water power plants and so on.
