本系统提供一种仓储环境无线传感器网络温度湿度监测系统,包括终端节点(End Device)、路由器节点(Router)、协调器节点(Coordinator)、烟雾检测传感器、监测主机。终端节点(End Device)有DA300温度湿度传感器板和长距离ZigBee高频模块组成。通讯距离是ZigBee技术走向应用的主要瓶颈之一,采用的CC2591放大器+CC2430单片机设计的LBee高频模块有效提高了节点间的通讯距离。为了提高无线网络分布距离本系统采用网状网络拓扑,为了减少终端节点(End Device)的功耗,把终端节点设置为半功能器件RFD,因此它可以是一个电池供电设备。
The system provides a storage environment temperature and humidity monitoring system for wireless sensor network, including End Device, Router, Coordinator, smoke detection sensor and monitoring host. End Device (End Device) DA300 temperature and humidity sensor board and long-distance ZigBee high frequency module. Communication distance is one of the major bottlenecks in the application of ZigBee technology. The LBee high-frequency module designed by CC2591 amplifier + CC2430 MCU effectively improves the communication distance between nodes. In order to improve the distribution distance of the wireless network, the system adopts a mesh network topology. In order to reduce the power consumption of the end device and set the terminal node as a semi-functional device RFD, it can be a battery-powered device.
