摘　　要：水产养殖过程中,为了实现溶解氧的实时监测和及时报警,提出一种C#和LabVIEW混合编程的溶解氧监测控制系统。LabVIEW负责数据采集,C#上位机程序通过调用LabVIEW生成的DLL,用户通过C#程序给LabVIEW发送采集命令,当LabVIEW接收到用户的命令后进行数据采集。系统的主要特点是在上位机上根据养殖水产品的养殖时段,动态调用溶解氧的预测算法,实时传递采集指令给各个LabVIEW子程序,将数据采集和数据分析处理分开,减少由于LabVIEW的串口轮询通信方式带来的CPU使用率。系统能够在当溶解氧超过设定的报警值时及时报警,确保养殖水环境参数正常。In order to realize real-time monitoring and timely alarm of dissolved oxygen（DO） in aquaculture, put forward a DO monitoring system based on C# and LabVIEW, LabVIEW is mainly responsible for data collection, C# call DLL generated by LabVIEW, users send acquisition command to LabVIEW through C# program, and after LabVIEW receive the user＇ s command, data acquisition is carried out. The main feature of this system is according to culture period of aquatic products, this system dynamic calls DO prediction algorithm on upper PC, real-time transmit acquisition instruction to various LabVIEW subroutines, separates data acquisition and data analysis and processing,reduce CPU usage rate brought by LabVIEW serial polling communication. The system can alarm in time when the DO is over the set,which can ensure aquaculture water environment parameters is normal.
