摘　　要：为解决某高超声速风洞攻角机构存在的传动结构复杂、负载大和精度要求高等问题,设计了以EtherCAT为总线的控制系统方案。根据攻角机构的控制系统需求,选用BECKHOFF产品构建攻角机构机电液一体化的控制系统架构,分别采用TwinCAT和C#语言开发控制系统下位机PLC和上位机HMI软件,采用ADS通信协议实现HMI与PLC程序的通信,并用OPC UA通信协议实现攻角机构运行数据与风洞运行系统的数据交互。结果表明:该系统满足攻角机构控制需求,能够解决攻角机构的信息孤岛问题,提高风洞系统的信息化和智能化水平。In order to solve these problems of complex transmission structure,large load and high accuracy requirements of certain type hypersonic wind tunnel attack angle mechanism,a control system scheme using EtherCAT as a bus was designed.According to the control system requirements of the attack angle mechanism,BECKHOFF products are used to build the electromechanical-hydraulic integrated control system architecture of the attack angle mechanism.TwinCAT and C#languages are used to develop the control system PLC and upper computer HMI software,and the ADS communication protocol is used to realize HMI and PLC program communication,and use the OPC UA communication protocol to realize the data interaction between the attack angle mechanism operation data and the wind tunnel operation system.The results show that the system meets the control requirements of the attack angle mechanism,and it can solve the problem of information islands of the attack angle mechanism,and improves the information and intelligence level of the wind tunnel system.
