Wireless monitoring device for electroplated SCR rectifiers

Abstract

A wireless monitoring device for an electroplated SCR rectifier includes at least one monitoring module, at least one operating module, a wireless relay module, and a back-end server data platform. The monitoring module is non-intrusively connected to the existing SCR rectifier through external electrical contacts to capture output voltage and current signals without altering the rectifier's internal circuitry. The operating module allows on-site operators to set constant voltage or constant current operating modes and parameters, and displays the electrical status in real time. The modules receive and transmit data through a bidirectional wireless communication interface. The wireless relay module centrally manages the data packets of each module and publishes them to the back-end server data platform for data integration and history storage. It supports energy consumption behavior marking, anomaly analysis, and query interface display, and features modularity, low cost, and rapid deployment.
