基于ZigBee的无线物联网传感系统

Wireless IoT Sensing System Based on ZigBee

传统环境监测领域的多点式传感器,存在多节点供电及布线困难或设备电池使用寿命短、节点成本高昂、扩展性差等痛点。针对上述痛点,该文设计开发了一种基于ZigBee无线传感网络系统。系统使用CC2530单片机作为终端节点联合多种传感器进行数据采集,设计ZigBee网关将终端节点所采集的数据转发至物联网云平台,用户可使用APP或者网页登录云平台进行远程查看系统终端节点状态信息,当系统监测到数据异常时向用户发送警报。系统性价比高、成本低廉,经测试,系统功耗相较于其他系统低,节点休眠电流仅为8μA,且可靠性和可拓展性高,能够在大棚养殖等对环境要求较高的行业进行部署使用,具有实际应用研究价值。

Traditional multi-point sensors in the field of environmental monitoring,there are multi-node power supply and wiring difficulties or short device battery life,high node cost,poor scalability and other pain points.In response to the aforementioned pain points,this paper has designed and developed a wireless sensor network system based on ZigBee.The system uses a CC2530 microcontroller as the terminal node and combines multiple sensors for data collection.A ZigBee gateway is designed to forward the data collected by the terminal node to the IoT cloud platform.Users can use an APP or webpage to log in to the cloud platform to remotely view the system’s terminal node information,and send an alert to the user when the system detects abnormal data.The system has high cost-effectiveness and low cost.After testing,the power consumption of the system is lower than other systems,and the node sleep current is only 8μA.And it has high reliability and scalability,which can be deployed and used in industries with high environmental requirements such as greenhouse aquaculture,and has practical application research value.
