灌区渠系水资源监测系统及灌溉优化调度管理

大型灌区水文监控跨越地域范围广,监测点数量多,在汛期或灌溉期要求系统通讯可靠,轮询响应时间短。文章通过在灌区干渠、支渠等适当位置配置一定数量的公网4G无线现场测量采集单元,组成了灌区渠系水资源监测系统,并以此为数据基础构成了灌区灌溉优化调度管理系统,对灌区节水灌溉方式进行了科学的优化管理,实现了灌区水资源统一调配,减少了渠道配水过程中的弃水,对提高配水精度和合理利用水资源具有重要生产实用价值。

The hydrological monitoring beyond geographical scope of the large irrigation area is wide,which needs reliable requirement system communications in the flood season or irrigation period and poll for the response time is short.In this paper,a monitoring system of water resources in irrigation area canal system is constituted by allocating a certain number of 4G wireless field measurement and acquisition units in the main canal and branch canal in irrigation area.Based on the data of monitors,the optimal operation management system of irrigation area is constructed.The water-saving irrigation mode is scientifically optimized and the unified allocation of water resources is realized.The abandoned water in the process of water distribution is reduced.It has important practical value for improving the accuracy of water distribution and rational utilization of water resources.
