基于FPGA的聚变装置关键设备在线监测系统
Multi-range voltage and temperature acquisition system based on FPGA
摘要
Abstract
In magnetic confinement fusion devices,numerous rotating mechanical components are present.Real-time monitoring of key parameters such as temperature,voltage,rotational speed,and vibration is crucial for ensuring the safe operation of both the equipment and the overall system.On this basis,an field-programmable gate array(FPGA)-based online monitoring system is designed to monitor the operating status of these key devices in real-time.In the system,the temperature acquisition channel with multi-range voltage conditioning and wide-temperature range is constructed and cooperated with the high-resolution analog-to-digital conversion module,so as to realize the dynamic acquisition and processing of weak signals.In the voltage acquisition module,a combination of segmented dynamic voltage division,isolated amplification,and digital filtering is used to ensure high-precision measurement over a wide range.For the temperature measurement,a constant current-excited platinum resistance sensor and a nonlinear inverse algorithm are used to realize the accurate measurements in the low-to-ambient temperature range.The testing results show that the system achieves voltage measurement accuracy better than 0.04%F.S.in the low range(within 1 V)and better than 0.02%F.S.in the high range(from 1 V to 10 V).Within the range from 20 K to 325 K,the temperature acquisition error does not exceed 0.13 K.This system supports multi-channel expansion,real-time data transmission,and visualization,making it suitable for equipment condition monitoring and fault prediction in high-demand experimental environments.关键词
