摘　　要：针对清江水情自动测报系统采用VHF通信组网方式将遥测站数据分别送宜昌中心站和水布垭中心站并返回确认信息,提出了一种单频无线组网设计方案,利用单站单路由发信多中心接收确认机制,解决系统传输时延与接收中心的数量成线性增长的难题。实践表明,该设计方案具有灵活的路由控制能力,设备具有高度的互换性,可应用于电力、水利和防灾等领域的监测和控制。A Very High Frequency radio communication is applied in Qingjiang hydrologic measurement system to transmit rain and water data collected by remote station to central station located at Yichang and Shuibuya, and return acknowledgement at the same time. The method of single frequency network for reception and acknowledgement by multiple central stations is introduced in detail, reducing total transmission delay time and confliction possibility, by reasonably arranging remote station transmission sequence and effectively designing route control protocol to realize single station trans- mission while multiple stations reception at the same time and resolve the problem of line relationship between delay time and acknowledgement station numbers. Featured with flexible transmission route control and feasible equipment interchange, this system is applicable to supervisory and control system for power electricity, water conservancy and disaster relief.
