一种基于LabVIEW的呼吸机控制系统设计

摘要

设计一种呼吸机控制系统,被控对象为比例阀和电机,以实现呼吸机的基本功能.采用LabVIEW设计的软件直接与硬件互连,进行硬件环仿真和算法设计的验证和评估.采用上层上位机和下层实时机运行无实时要求和有实时要求的程序,上下层之间通过TCP/IP通信.软件程序设计模块化,可扩展性强,易于维护,并且可以方便地将原型开发阶段的成果无缝连接到实际的嵌入式产品,加快开发速度,提高开发效率.%This paper designed a ventilator control system to control Proportional Valves and Motors.It used LabVIEW to control the object mentioned above and design ,validate, evaluate arithmetic, and establish hardware in loop platform.There are two system's hierarchies.The high layer was used to run non-real time program and the low layer was used to run real time program.The two layers communicated through TCP/IP net.The program can be divided into several modules,which can be expanded and maintained easily.And the harvest in the prototype designing can be seamlessly used to embedded products.From all above, this system was useful in employing OEM products.
