摘要
无线传感器网络能够实时监测、感知和采集网络分布区域内的各种环境或监测对象的信息,但是无线传感器网络节点能耗高、容易失效。针对这一问题,提出一种基于PSoC的无线传感器网络系统设计方案,采用CYPRESS公司PSoC芯片(可编程片上系统)CY8C29466作为节点处理器,实时采集网络各节点的电池电量,引入抗干扰能力较强的Wire-lessUSB通信技术构建无线网络,提高无线数据传输的可靠性,以车位锁管理系统设计为例,详细阐述了该传感器网络系统的硬件和软件设计。实际应用结果表明,该方案充分利用PSoC芯片内部的模拟资源和数字资源,缩小了体积,缩短开发周期,且能有效地降低系统的能耗,检测网络各节点当前的电量,通知管理人员及时更换电池。
Wireless sensor network can collect the information of the objects in network, but power consumption of sensor nodes is high and sensor nodes can easily fail. In order to solve this problem, wireless sensor network based on PSoC is introduced in this paper. It adopts PSoC chip CY8C29466 as the processor to monitor the sensor nodes voltage, and uses wirelessUSB communication to improve the reliability of data transmission. As an example, the paper discusses the hardware and software design of a parking lock in detail . Ex- periments show that the system takes full advantage of digital and analogy resources of PSoC, and it can effectively decrease the scale, shorten the development cycle, Also it can reduce the energy consumption and detect the power of each node to inform the manager to replace battery in time.
