摘　　要：大型灌区监控系统互联是数字化灌区的物理平台。搭建这些平台可以实现节约用水与水利资源的综合调度,有利于灌区经济的可持续发展。由于这些监控系统分布在边远地区,实现它们的互联已经成为数字化灌区建设的一个关键性技术。文中根据陕西省交口抽渭管理局田市抽水站远程监控系统工程实践,详细论述了无线网桥、无线天线等设备的选型、以及它们的安装设计和调试,为今后数字化灌区建设提供了一些参考。The interconnection of the monitoring system of large irrigating area is a pnysical platiorm of digital irrigating area, Building the platform can economize water and realize the integrative distribution of water resource, It＇s beneficial to the sustainable development of the economy. Because these monitoring systems are in remote area, the interconnection between them has become a key technical problem. According to the remote monitoring system of tian shi pumping station of shaanxi jiaokou WeiRiver pumping management bureau of pumping Wei River of shaanxi, the antenna selection, installation design and debugging of the facilities of wireless bridge and wireless aerial are briefly described, Experience is offered for the network interconnection of the monitoring systems of digital irrigating area.
