Wireless Sensor Network Node Design Based on PSoC

无线传感器网络节点的优劣直接关系到无线传感器网络的生存周期及其传递的数据的可靠性。用PSoC(可编程片上系统)作为处理器模块的处理器,运用于无线传感器网络节点的设计之中,使无线传感器网络节点降低功耗,缩小体积,提高可靠性,降低成本,增加生存周期,缩短开发周期。论文首先简单介绍了PSoC独特的内部资源及其特有的功能,然后详细阐述了采集环境的温度和湿度的无线传感器网络节点的硬件电路和处理器模块的软件设计方案。最后给出了实验结果,其实测结果表明设计的传感器系统性能良好。

The quality of wireless sensor network node can directly affect the life span of wireless sensor network and the reliability of its data transmitting. PSoC（Programmable System On Chip）is used as the processor of the processor module in the design of wireless sensor network node in order to reduce the power consumption, shrink the size ,lower the cost,improve the dependability and life span , and shorten the circle of developing of the node. Firstly the particular inner resource and basic function of PSoC are briefly described, and then the hardware and software design of wireless sensor network node for gathering environmental temperature and humidity are discussed in detail, finally the test results were given which show that the sensor system runs well.
