摘　　要：为了对无线传感器网络在实际环境下进行综合性能测试,设计了一种无线传感器网络测试系统;各测试模块挂载到CAN总线上,有利于数据的快速传输,增加了可测试节点的数量并提高了数据传输的实时性;提出一种动态优先级方案,解决了静态低优先级节点竞争不到CAN总线造成的数据拥塞;针对无线传感器网络节点数量大、烧录效率低的特点,利用MSP430的Bootstrap Loader特性,实现了对WSN节点的并行程序烧录,提高了烧录效率;此外,还支持对WSN节点的电源控制、能耗测试、程序调试及状态查询。实验数据表明,该测试系统满足无线传感器网络的测试要求。To achieve the comprehensive performance testing of WSNs in a real environment, this paper proposes a testing system for WSNs. Mounting each test module to the CAN bus can speed up the transmission speed, increase the amount of mounted nodes and enhance the real--time performance. In order to solve the data congestion as a result of static low--priority nodes can＇t compete CAN bus, the system proposes a dynamic priority solution. Aiming at large quantity and low efficiency of the WSNs nodes＇ burning, the system programs WSNs nodes in parallel via the MSP430＇s Bootstrap Loader. In addition, the system also supports the WSNs nodes＇ power control, energy consump- tion testing, debugging and status inquiry. Test results show that this system meets the test requirement.
