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 networks can monitor, perceive and collect the information of various environments or monitoring objects in the network distribution area in real time. However, the nodes of the wireless sensor network consume high energy and are prone to failure. To solve this problem, this paper proposes a design scheme of PSoC-based wireless sensor network system. CYPRESS PSoC chip (Programmable System-on-Chip) CY8C29466 is used as the node processor to collect the battery power of each node in the network in real time and introduce the anti-interference ability Wire-lessUSB communication technology to build a wireless network to improve the reliability of wireless data transmission to parking lock management system design, for example, elaborated on the sensor network system hardware and software design. The practical application shows that this scheme makes full use of the analog resources and digital resources in the PSoC chip, reduces the size and shortens the development cycle, and can effectively reduce the system energy consumption, detect the current power of each node in the network, and notify the managers to replace them in time battery.
