Abstract
With the rapid development of smart grid and IoT technology, the accuracy and intelligence level of electrical power meter measurement systems have become a research hotspot. The traditional electrical power meter measurement system has problems such as single functionality and low level of intelligence, which makes it difficult to meet the needs of modern power management and energy utilization. Therefore, developing an intelligent and multifunctional electrical power meter system has important practical significance.
This design is based on the STM32F103C8T6 microcontroller, integrating various sensor technologies and wireless communication technologies to construct a fully functional electrical power meter system. The system obtains current electrical parameters such as voltage, resistance, current, and power through voltage, resistance, current, and power monitoring modules; Real time monitoring of environmental temperature through temperature detection module DS18B20. When the temperature exceeds the preset threshold, the system automatically triggers an audible and visual alarm to ensure the safe operation of power equipment; Users can flexibly set the temperature alarm threshold through the button module, enhancing the flexibility and user friendliness of the system; The OLED display screen displays real-time electrical parameters, temperature, and system status, providing an intuitive user interface; The WiFi module transmits real-time detection data to the mobile phone, enabling remote monitoring and data management.
The electrical power meter system designed in this study has significant application value. It achieves an organic combination of high-precision measurement and intelligent management, effectively improving the accuracy and intelligence level of the electrical power meter system. Through real-time monitoring and remote management functions, the system not only ensures the safe and stable operation of power equipment, but also optimizes energy utilization, providing strong support for the construction and energy management of smart grids.
