Design of security monitoring system based on multi-sensor data fusion

Aiming at the single monitoring technology of the existing building security monitoring system, a building monitoring system based on IoT and multi-sensor fusion is designed and developed. The system focuses on addressing sensor false alarms and enabling remote real-time monitoring. The main control unit of the system is the STM32F103ZET6 MCU, which collects real-time indoor air quality data through various sensors and captures real-time video streams using a network camera. By utilizing multi-sensor data fusion technology, the system incorporates the ESP8266 wireless communication module, relay module, and infrared module to establish wireless remote linkage monitoring of the building's environment and video on the cloud platform. Additionally, it enables infrared remote control of the equipment within the building. Test results demonstrate the system's effectiveness in avoiding false alarms caused by a single sensor through multi-sensor data fusion technology. Moreover, the system's infrared remote control feature ensures easy operation and effective control of various devices via the cloud platform.
