基于Simulink以太网通信模块及数据采集卡构建半实物仿真系统

Hardware-in-the-loop Simulation System Based on Simulink Ethernet Communication Modules and Data Acquisition Card

随着信息科学技术的发展,在控制工程领域,传统的串口通信渐渐无法满足当前移动化、多样化的通信需求。提出了一种基于Simulink以太网通信模块及数据采集卡构建半实物仿真系统的实现方法,系统由以C8051F020单片机为核心设计的硬件板卡和上位机软件组成,上位机软件为MATLAB/Simulink,计算机与数据采集卡之间采用USR-WIFI232-T串口转Wi-Fi模块按照通信协议进行通信,并通过一个PID控制实例验证了实际控制效果。

With the development of information science and technology,in the field of control engineering,the traditional serial communication gradually can not meet the current mobile,diversified communication requirements.This paper presents a method to build a hardware-in-the-loop simulation system based on Simulink Ethernet communication module and data acquisition card.The system is constructed with the hardware,which is based on C8051 F020,and the upper computer software,which is based on MATLAB/Simulink.The communication between computer and the data acquisition card is based on USR-WIFI232-T serial port to Wi-Fi module by means of the communication protocol,and the actual control effect is verified by a PID control example.
