电网数据采集系统设计：基于单片机，波动监测优化

Abstract: The use of voltage-sensitive appliances and devices in households and laboratories requires their voltage levels to be consistently monitored to avoid errors or damage caused by voltage fluctuations. In this study, a voltage acquisition system using the Lingyang SPCE061A microcontroller as the central control device is designed. A Hall voltage sensor is utilized to collect data on the 220V, 50Hz voltage signal. Through voltage conditioning circuitry and filtering, a DC voltage signal suitable for the microcontroller is obtained. The sampled signal is then analyzed and processed, and the results are compared with a preset reference value for real-time output through LEDs. This design encompasses various disciplines, including linguistics, computer science, signal processing, and analog-to-digital conversion, and it can be widely applied in coal mines and manufacturing industries. The technology presented in this study has a promising application outlook. Keywords: microcontroller, fluctuations, monitoring, data acquisition, filtering.
