针对车辆冷却系统测控试验平台中的数据实时采集和电机控制问题,利用三层架构的开发思想,基于C#语言、Measurement Studio控件以及SQL Server数据库,在上位机中结合数据采集卡和传感器等硬件设计开发了车辆冷却系统的测控软件。详细介绍了三层架构的数据访问层、业务逻辑层、表示层在测控程序中的具体实现过程,完成了对测控数据的实时采集、存储与处理,绘制了测控数据实时曲线和历史曲线,以及实现了对风扇电机和水泵电机的控制等功能。同时,利用多次实验对测控程序的可靠性及稳定性进行了测试。实验结果表明,基于三层架构框架指导开发的软件具有更好的可读性、维护性和扩展性,满足车辆冷却系统试验平台的测控要求。Aiming at the problem of real-time data acquisition and motor control for vehicle cooling system test-bed,using the development thought of 3-access architecture,the measurement and control software of the vehicle cooling system was designed and developed by C #,Measurement Studio control and SQL Server database based on the hardware of data acquisition card and sensor in the host computer. The realization process of 3-access architecture of DAL,BLL and UI were introduced in detail in the measurement and control program,it finished real-time acquisition,storage and processing of measurement and control data,real-time curves and history curves,fan motor control and water pump motor control,and other functions. At the same time,the reliability and stability of the program were tested by several experiments.The results indicate that the software can improve the readability,maintainability and expansibility of the program,and meet the requirements of measurement and control based on 3-access architecture.福建省自然科学基金资助项目(2014J01210);; 深圳市科技计划项目(JCYJ20140417162429675
