ABSTRACT

The traditional water pressure detection method relies on a single sensor, which has the problem of insufficient detection accuracy and stability. Therefore, this system integrates various types of sensors and adopts advanced data fusion algorithms, such as weighted average and D-S evidence theory, to comprehensively analyze the sensor data, so as to improve the detection accuracy and stability. The system adopts hierarchical design idea, including data acquisition layer, data fusion processing layer, data transmission layer and user interface layer. In the hardware part, STM32F407VGT6 microcontroller and ESP8266 Wi-Fi module are selected to ensure the efficient processing and stable transmission of the system. In software design, the lower computer is responsible for data acquisition and preprocessing, while the upper computer realizes data reception, storage, display, analysis and alarm. The experimental results show that the multi-sensor fusion measurement method shows higher detection accuracy and stability than a single sensor under different water pressure conditions, and the error range is significantly reduced. The system provides strong support for intelligent management in water supply system, building fire protection and industrial environment monitoring, and has broad application prospects.
