基于西门子S7-300 PLC的电子密码锁系统设计
Design of electronic lock systems based on SIEMENS S7-300 PLC
摘要
Abstract
The SIEMENS S7-300 PLC(Programmable Logic Controller) has been widely applied in industrial control systems, but there were few related researches of coded lock.In this paper, a class of embedded electronic lock systems is designed to control the industry devices based on SIEMENS S7-300 PLC.Integrating the decryption and encryption for the systems with PLC control principles, the systems can be directly applied to ensure the anti-theft function of the industry devices.Finally, the systems are programmed and tested by using STEP 7 SIMATIC, and the simulation results show that the lock is reliable and effective.关键词
