高速公路绿化隔离带节水灌溉系统漏水故障诊断模型研究

Research on Model of Water Loss from Irrigation Pipe in the Middle Isolated Grassland of Highway

系统不同破坏形式的漏水量根据位置不同而变化,滴灌系统主要漏水形式是滴头断裂漏水和滴灌管破裂漏水。高速公路2.05km滴灌试验段测试表明,内镶式滴灌管滴头和管上式滴头灌水均匀度Cu分别为90%和89%。根据实测系统流量数据,分析建立具有数据实时更新与记忆衰减功能的漏水故障诊断模型,实际应用表明:该模型漏水报警及时,操作简便。。

Water loss varies with the pipeline, the maintenance of grassland is the main reason of the system destroy, and the uniformity coefficient of the drip line and emitter is 90% and 89%. The running of automatic control system in demonstration area indicates that the control system can stop the irrigation system in time and set back warning message with the model when water loss happens.
