摘要：
物理安全系统与环境安全监测的整合是智能基础设施管理中的关键进展。传统方法将这些系统保持为独立的孤岛，导致操作效率低下、响应延迟和管理复杂性增加。本文提出了一种全面的双模物联网框架，通过统一的云架构将基于RFID的访问控制与多传感器环境安全监测无缝整合。系统包含两个协调的子系统：子系统1实现基于RFID的认证，配备伺服电机门控和实时Google表格记录；子系统2提供全面的安全监测，包括火焰检测、水流量测量、LCD状态显示和人员识别。两个子系统均使用ESP32微控制器进行边缘处理和无线连接。经过45天的实验评估，系统表现出卓越的性能指标：99.2%的RFID认证准确率，0.82秒的平均响应时间，98.5%的火焰检测可靠性（5米范围内），99.8%的云数据记录成功率为。系统通过智能本地缓存机制在网络中断时保持运行完整性，并实现了总实施成本为5,400元人民币（约48美元），相比商业集成解决方案减少了82%。本研究建立了一个实用的框架，证明通过精心的架构设计和组件优化可以实现专业级的性能，同时保持出色的成本效益和对多种应用场景的适应性。
英文摘要：
The integration of physical security systems with environmental safety monitoring represents a critical advancement in smart infrastructure management. Traditional approaches maintain these systems as independent silos, creating operational inefficiencies, delayed emergency responses, and increased management complexity. This paper presents a comprehensive dual-modality Internet of Things framework that seamlessly integrates RFID-based access control with multi-sensor environmental safety monitoring through a unified cloud architecture. The system comprises two coordinated subsystems: Subsystem 1 implements RFID authentication with servo-actuated gate control and real-time Google Sheets logging, while Subsystem 2 provides comprehensive safety monitoring incorporating flame detection, water flow measurement, LCD status display, and personnel identification. Both subsystems utilize ESP32 microcontrollers for edge processing and wireless connectivity. Experimental evaluation over 45 days demonstrates exceptional performance metrics: 99.2\% RFID authentication accuracy with 0.82-second average response time, 98.5\% flame detection reliability within 5-meter range, and 99.8\% cloud data logging success rate. The system maintains operational integrity during network disruptions through intelligent local caching mechanisms and achieves total implementation cost of 5,400 BDT (approximately \$48), representing an 82\% reduction compared to commercial integrated solutions. This research establishes a practical framework for synergistic security-safety integration, demonstrating that professional-grade performance can be achieved through careful architectural design and component optimization while maintaining exceptional cost-effectiveness and accessibility for diverse application scenarios.
