评价WSN可靠性的故障注入记录仪设计

Design of Fault Injection Recorder for Evaluating the Reliability of WSN

针对无线传感器网络设计一种故障注入串口数据记录仪,其硬件系统包括主控芯片、电源模块、LED指示模块、通信模块、存储模块和时钟模块等部分,通过串口以一对一的方式与WSN节点连接,以实时/定时的方式向WSN节点注入故障命令,将实际应用领域遇到的故障和干扰注入到WSN中,并观察网络运行的状况,以分析和评价WSN的可靠性。

A Serial Data Recorder with the function of fault Injection for WSN was designed. The hardware system is mainly composed of main control chip, power module, LED display module, communication module, storage module and clock module. It connects to WSN nodes through serial port by one-to-one, injects fault command to WSN nodes with real time/timing mode. The FISDR can effectively inject various practical faults and interference into the WSN likely to be encountered, and observe the network reaction for analyzing and evaluating the reliability of WSN further.
