Detection Technology of UHF IoT Sensing Terminal Device Based on Cloud Edge Cooperation

CODEN: JTEVAB

Abstract

The local release detection technology of traditional Internet of Things (IoT) sensing terminal equipment cannot realize the integration of the cloud and IoT edge, resulting in obvious local release detection errors and low technical sensitivity. To this end, a local release detection technology comprising ultra-high frequency (UHF) IoT sensor terminal equipment based on cloud edge collaboration is proposed. The transient earth voltage signal coupling module of the perception layer is used to collect data locally published by the device. This paper uses edge computing to reduce information redundancy. The cloud computing application layer adopts the time difference positioning method to realize the partial discharge detection of the UHF IoT sensor terminal equipment. When an abnormality occurs in the terminal equipment, an alarm is triggered. The experimental results show that the average accuracy of this method in detecting partial discharge is as high as 93.89 %. The detection time of this method is short and its detection time of partial discharge phenomenon is as low as 4 ms. The fitting effect of the proposed method is better in detecting amplitude and discharge and the two have a linear relationship. This method also has higher detection sensitivity, can detect the partial discharge of different types of terminal equipment, and its application effect is good.
