摘要 针对电源系统需要为系统中微处理器、传感器、信号调理电路、无线通讯模块等提供工作电源的目的,提出一种生物信息检测系统中无线传感器网络(WSN)节点的电源设计方案。除了通过内部3.7 V锂电池,振动产生的机械能也可以用来提供能量。系统工作过程中能自动对供电方式进行选择,并完成对锂电池的充电任务。节点采用带有8051内校的CC2430无线射频芯片,通过有效的动态电源管理和唤醒休眠机制的软件设计,针对生物信息检测系统实现了一种低功耗的能量自供给的无线传感器节点电源设计。 For the power system supplied reliable energy to micro-controller,sensor,signal conditioning circuit and wireless communication module,a design of power system in WSN node is inrtoduced.In addition to the internal 3.7 V lithium battery,vibration energy can also provide energy.System working process of the power supply can automatically select and complete the task of charging lithium batteries.Node uses CC2430 RF chip with a 8051 core microprocessor.Through effective dynamic power management and software design of wake-sleep mechanism.At last a low-power energy and the power supply design of wireless sensor nodes for biological information detection system is achieved.
