摘要
针对目前消防安全出口标志灯功能单一且不能互联,以及楼宇智能化中ZigBee无线网络通信距离短、抗干扰能力弱、网络协议复杂、误码率高、数据采集误差大、应用成本高等问题,该文提出一种基于物联网智能消防监控系统的方案。该方案以LORA技术为核心,采用扩频调制跳频技术,具有超强的抗干扰能力,衍射能力强;最后对系统进行测试分析,实测结果表明:该系统具有功能多样化、能够互联接入网络,组网便捷,数据误差小,灵敏度高,延迟性低可靠性强,传输速率高,穿透能力强,应用成本低,通信距离远等特点,可广泛应用于智能楼宇化和智慧城市建设中。
In view of the fact that the fire safety exit sign lights have a single function and cannot be interconnected,and the ZigBee wireless network has short communication distance,weak anti-interference ability,complicated network protocol,high bit error rate,large data acquisition error and high application cost.A solution based on the intelligent fire monitoring system of the Internet of Things is proposed.The scheme adopts LORA technology as the core and adopts spread spectrum modulation frequency hopping technology,which has superior anti-interference ability and strong diffraction ability.Finally,the system is tested and analyzed.The measured results show that the system has diversified functions and can be interconnected.The network,convenient networking,small data error,high sensitivity,low delay,high reliability,high transmission rate,strong penetrating ability,low application cost and long communication distance can be widely used in intelligent building and smart city construction.in.
