摘要
目前设计的超声速风洞控制系统软件采集精准度低,软件程序安全性差;基于PMAC开发设计了一种新的超声速风洞控制系统软件,通过Windows XP平台中的语言编辑器开发与调试程序,选择PMAC运动控制卡操作控制程序,利用XP系统进行程序协调,完成程序内的上位机与通信模型的数据编写,在64种功能函数下计算和提取程序代码,根据3个独立的风动参数进行PID计算,应用集成软件统一配置计算机中的软件资源,确保在程序的控制下其他软件程序可以自行执行相应的工作,以Fame View组态软件作为此程序的运行基础,采用C++语言编写,开发监控程序;实验结果表明,基于PMAC的超声速风洞控制系统软件采集精准度得到了提高,监测范围较大,且监测波动较稳定,有效保证了软件程序的安全性。
At present,the software of the control system of supersonic wind tunnel is designed with low accuracy and poor security.Based on PMAC,a new control system software of supersonic wind tunnel is developed and designed.Through the language editor develop and debug program in XP platform,PMAC motion control card operation control program is selected,program coordination is carried out by XP system,data compilation of upper computer and communication model in the program is completed,program code is calculated and extracted under 64 functions,PID calculation is carried out based on three independent wind parameters,and software in the computer is uniformly configured by integrated software.To ensure that other software programs can perform their own work under the control of the program,the Fame View configuration software is used as the operation basis of the program,and the C++language is used to write and develop the monitoring program.The experimental results show that the accuracy of the software acquisition of the control system of the supersonic wind tunnel based on PMAC is improved,the monitoring range is large,and the monitoring fluctuation is relatively stable,which effectively guarantees the safety of the software program.
