摘要
灵活可扩展的高性能无线传感器网络硬件是支撑科学研究与工程实践必不可少的基础平台。以高性能低功耗的STM32微控制器和高灵敏度CC2520无线收发器为核心芯片,设计开发了基于Cortex内核的新一代32位传感器网络开源硬件平台OpenWSN节点,并提供了符合通用模块互联总线规范的外扩接口,以方便与各种传感器和外扩功能板连接。在开源OpenWSN软件的支持下可快速构建传感网研究与应用平台。该设计遵循低功耗、高扩展、高可靠、低成本和微型化原则,实测表明具有良好的传输性能和低功耗特性,为进一步开展同步振动测量等高性能传感网应用奠定了良好基础。
High performance wireless sensor network hardware is essential to scientific research and engineering practice. A new generation wireless sensor node design is proposed and implemented in this paper targeting at high performance applications such as distributed vibration measurements. It adopts the high-performance and low-power Cortex-M3 based STM32 microcontroller and the high-sensitivity wireless transceiver CC2520. In order to connect various potential measurement modules, a lightweight module level interconnect bus called MXB is also proposed to extend the core module functionalities. With the support of the open source OpenWSN software, a sensor network application can be easily established based on this hardware. The whole design follows the principle of low energy consumption, scalability, and low cost. The tests show that the node exhibit good transmission performance and will be good platform for high performance sensor network applications.
