无线传感器网络数据冲突检测系统设计

无线传感网络传感器节点通过自组织网络进行数据信息交互。由于每个传感节点仅能获得局部信息，容易在数据信息交互过程中引发数据冲突，因此设计一种基于CSMA/CA协议的无线传感器网络数据冲突检测系统，主要包括TC35I电源模块、传感器节点检测模块、无线通信模块、手持式检测终端、主处理器STM32F103VB、无线打印机等。系统通过分析对比每个传感节点对数据包的接收状态，实时检测无线传感器网络中潜在的数据冲突|同时，数据冲突检测结果通过上位机软件进行实时显示，具有结构简便、组网简单等特点，可以方便地拓展到其它无线网络中。

Design of Data Conflict Detection System in Wireless Sensor Networks

The sensor nodes in the wireless sensor network exchange data information through the self-organizing network. Since each sensor node can only obtain local information，it is easy to cause data conflict in the process of data information interaction. A data collision detection system based on CSMA/CA protocol in wireless sensor network is designed， which mainly includes TC35I power module and sensor， node detection module， wireless communication module， hand-held detection terminal， main processor STM32F103VB， wireless printer， and the like. The system detects potential data conflicts in the wireless sensor network in real time by analyzing and comparing the receiving status of each sensor node to the data packet. At the same time， the detection result of the data conflict is displayed in real time through the upper computer software， and has the characteristics of simple structure and simple networking， and can be easily extended in other wireless networks.
