"基于单片机的电网实时监测系统设计及应用"

Based on the document "Design of Grid Data Acquisition System Based on Single-chip Microcomputer - Graduation Thesis.doc", this summary provides an overview of a voltage monitoring system using a single-chip microcontroller as the core control device. The purpose of this system is to monitor the voltage in real-time to ensure the proper functioning and protection of high-voltage appliances and equipment in households and laboratories. Fluctuations in voltage, either too high or too low, can cause errors or damage to these devices. To address this, the system utilizes the Lingyang SPCE061A single-chip microcontroller to control the voltage acquisition process. The system incorporates a Hall voltage sensor to collect data from a 220V, 50Hz voltage signal. The voltage conditioning circuit and filter are used to adjust and filter the signal to obtain a direct current (DC) voltage signal suitable for the single-chip microcontroller. The system then performs analysis and processing of the sampled signal and compares it with the preset reference value. The results are displayed in real-time using LEDs. The design of this system involves various fields such as linguistics, computer science, signal processing, and analog-to-digital conversion. It has wide applicability in coal mines and manufacturing industries. The technology used in this system holds great potential for future applications. Keywords: single-chip microcontroller, fluctuations, monitoring, data acquisition, filtering.
