For the problems of single function,massive data quantity and numerous monitoring dead zone of the large building safety monitoring,the large⁃scale building security monitoring system based on ZigBee was designed,in which the sensor net⁃work structure with multiple coordinator nodes is used to solve the monitoring problem. The microcontroller CC2430 with low⁃power consumption is adopted by the ZigBee network node to collect the temperature,humidity,smog and infrared data in the building through multiple sensors. The management center can perform the visual management for each node. The administrator can query the node information while receiving the alarm information,and notice the security guard to deal with and the inhabit⁃ant with SMS after determining the node location. The experimental results show that the system can acquire the data reliably and implement the local alarm function,and the management center can query the information of each network node.%针对现有大型楼宇安全监控功能单一、数据量大、监控盲区多的问题，设计基于ZigBee的大型楼宇安全监控系统，通过采用多个协调器节点的传感器网络结构解决监控难题。ZigBee网络节点采用低功耗的CC2430微控制器，外接多个传感器采集楼宇内温度、湿度、烟雾、红外等数据。管理中心对各个节点进行可视化管理，若收到报警信息，管理员可查询节点信息，确定节点位置后通知保安前去处理，同时以短信的方式通知住户。实验结果表明，系统能够可靠完成数据采集并完成本地报警功能，管理中心能够查询各网络节点信息。
