Description

基于Zigbee无线网络的仓库监控系统 技术领域
本发明属于仓库监控技术领域，具体地涉及一种基于Zigbee无线网络的仓库监控系统。
背景技术
仓库是现代工业生产中物料流转常用的存储空间，如果物品存储不当，发生存放混乱或遗失，会导致大量的经济损失，给企业及个人造成直接的利益伤害，所以需要实时监控，避免危害的产生。传统的仓库监控手段通过人工方法进行监控，存在效率低下、开销巨大、安全性差、可靠性低等弊端；并且对仓库运行数据记录不详，难以对仓库运行状态做出有效的分析。
现在一般都会在仓库中安装摄像头，例如，公告号为CN 109194925的专利，公开了一种仓库用远程视频监控系统，包括视频采集终端、云平台和远程监控端，所述视频采集终端用于采集仓库中的监控视频，并将采集的监控视频无线传输至云平台，所述远程监控端与云平台无线连接用于远程查看采集的监控视频。缺点是需要人工时刻监控视频，并通过人工进行判断，大大增加了人工成本。但是如果通过软件的识别算法进行识别的话，同样会增加监控的成本。
虽然现有技术中也会通过传感器进行仓库监控，但是往往都无法进行全面的监控。
