摘要：溶解氧检测在水产养殖中起着至关重要的作用。研制了一套通过无线以太网（WIFI）连接，LabVIEW程序控制，并通过GSM网络使用户远程监控池塘溶解氧的溶解氧无线监测与控制系统。该系统能够在线检测溶解氧、温度等主要环境参数，并根据环境情况实施对增氧机的控制，业主可远程电脑监控或者通过手机远程监测鱼塘水质状况，并发送增氧命令，进行远程手动启停增氧机。在溶解氧超标时，系统可以自动启停增氧机，并向用户发送报告。试验结果表明，该方案提高了水质监控系统的控制性能，且具有应用前景。

Abstract: Dissolved oxygen monitoring plays an important role in aquaculture. A dissolved oxygen monitoring and control system is described in this paper which uses WIFI to build the net, LabVIEW to control the system and the GSM network to communicate with remote users. The dissolved oxygen concentration, temperature and other key environmental parameters could be detected online in the system, and the aerator could be controlled based on the environmental situation. The fish ponds could be monitored by the owner through remote computer or cell-phone. The results showed that the system significantly improved the controlled quality of the water quality monitoring system, and the application prospect is broad.

Key words: dissolved oxygen; wireless detection; control system
