ABSTRACT

To address the issues of isolated sensing nodes and decentralized control and decision-making in traditional smart community management systems, we have designed and implemented a smart community control system based on multi-node collaborative sensing and control. The system employs a master-slave dual-MCU distributed architecture, integrating multi-source sensors such as temperature, smoke, infrared heat detection, and light sensors, and incorporating modules such as RFID and IC card readers. It comprises five sub-control nodes: lighting, fire and theft prevention, access control, parking management, and Bluetooth relay control. Through multi-source data fusion via edge MCUs, the system enables fire risk assessment and graded alarms for the residential community. Joint hardware and software testing results indicate that all nodes function normally, data transmission is stable, control is effective, and measurement errors for all sensor monitoring values are within acceptable limits. Under multi-parameter joint evaluation, the system effectively suppresses false alarms and accurately triggers the highest-level alarm in simulated open-flame scenarios. This solution provides a feasible reference for the construction of low-cost, highly reliable smart residential communities.
