摘　　要：由于外界环境会影响传感器的工作性能,在进行农田滴灌巡视车巡检数据采集过程中,通常会出现数据采集质量较差的情况。对此,提出基于物联网的农田滴灌巡视车巡检数据自动采集方法。首先以网络覆盖率以及均匀度作为传感数据质量的评估指标,对其设定相应的质量阈值,以此调整传感器的部署数量以及密度,实现巡检车上的传感器部署。其次构建混合感知模型,感知巡检车的传感节点,从而削弱传感节点感知外界环境变化的能力。最后采用物联网技术中的无线通信协议,为传感器节点配置相应的协议栈,从而得到完整的巡检数据采集结果。在实验中,对提出的方法进行了采集质量的检验。最终的测试结果表明,采用提出的方法自动采集巡检车巡检数据时,采集结果的冗余度较低,具备较高的数据采集质量。Due to the influence of external environment on the working performance of sensors,poor data collection quality often occurs during the data collection process of agricultural drip irrigation inspection vehicles.A method based on the Internet of Things is proposed for automatic collection of inspection data by agricultural drip irrigation inspection vehicles.Firstly,network coverage and uniformity are used as evaluation indicators for sensor data quality,and corresponding quality thresholds are set to adjust the deployment quantity and density of sensors,achieving sensor deployment on inspection vehicles.Then,a hybrid perception model is constructed to perceive the sensing nodes of the inspection vehicle,thereby reducing their ability to perceive changes in the external environment.Finally,the wireless communication protocol in the Internet of Things technology is adopted to configure the corresponding protocol stack for the sensor nodes,thereby obtaining complete inspection data collection results.In the experiment,the collection quality of the proposed method was tested.The final test results indicate that the proposed method has low redundancy and high data collection quality when automatically collecting inspection data from inspection vehicles.
