Circuit Design and Simulation Implementation of Intelligent Access Control System

摘要: 针对当前智能门禁系统上位机和下位机交互研究较少的问题，提出了上位机、下位机、串口电路的智能门禁系统一体化电路仿真模型。首先设计了由输入电路、控制器、报警电路等模块构成的下位机系统，并利用Keil、Proteus等软件和C语言实现电路控制功能；然后通过C#语言完成了上位机数据采集、密码更换和重置功能；最后通过串口通信组件实现了上位机和下位机的数据通信，并完成了整体电路测试整机测试。结果表明，智能门禁系统仿真模型初步具备了上位机和下位机数据交互的能力，为进一步深化系统研究奠定了模型基础。

Abstract: A simulation model of the intelligent access control system circuit is proposed to address the lack of research on the interaction between the upper and lower computers in the current intelligent access control system. Firstly, a lower computer system consisting of input circuits, controllers, alarm circuits, and other modules was designed, and circuit control functions were implemented using software such as Keil and Proteus, as well as C language; Then, the upper computer data collection, password replacement, and reset functions were completed using C# language; Finally, the data communication between the upper computer and the lower computer was achieved through serial communication components, and the overall circuit testing of the entire machine was completed. The results indicate that the simulation model of the intelligent access control system has the preliminary ability to interact data between the upper computer and the lower computer, laying a model foundation for further deepening system research.
