Intelligent state parameter monitoring system of SF ₆ high-voltage circuit breaker

The data transmission model with dual FIFO is designed and a design approach based on FPGA and ARM technology is proposed for real-time data acquisition, processing and remote transmission system, which adopts the architecture of FPGA + ARM + IPC and integrates the functions of data sampling, processing, communication and management to monitor in real time the state parameters of multiple SF ₆ high-voltage circuit breakers, such as temperature, insulation, electric/mechanical variables, etc. CAN bus is applied to realize the reliable communication with superordinate IPC. Experiment shows that the proposed system monitors entire parameters with high reliability and accuracy.
