水产品冷藏车无线传感器网络节点设计——基于CC2530

Design of Wireless Sensor Node for Refrigerated Truck of Aquatic Products — Based on CC2530

为了降低水产品物流中的损耗,必须对冷藏车内的温湿度进行实时监测。为此,以ZigBee技术为基础,应用CC2530片上系统和SHT11数字温湿传感器,设计开发了一种冷藏车智能无线传感器节点,并描述了节点的硬件设计和软件工作流程。经过对后续节点灵敏度和传感器节点精度测试表明,节点完全适用于冷藏车的物流全过程。

In order to reduce aquatic product quality loss and achieve real-time monitoring of the temperature and hu- midity in the refrigerated trucks during the transport, this article develops an intelligent wireless sensor network node which is based on ZigBee protocol, applying CC2530 System on Chip and SHT11 digital temperature and humidity sensor. Further on, the research showed that the design of nodes and the process of software. Subsequent testing for the node sen- sitivity and the sensor node performance showed that aforementioned nodes can be applied on the refrigerated trucks.
