| 摘 要： | 针对电池供电的传感器网络节点电能受限问题，设计实现了一种新型的结合太阳能电池和锂电池供电的节点双电源供电系统。设计采用IAP15F2K612S2低功耗芯片和太阳能板、锂电池；通过软件优化节点供电，采用BQ24650电源管理芯片实现对锂电池的充电控制，以单片机IAP15F2K612S2为微处理器，监测锂电池的电压放电情况，放电控制电路经过DC/DC转换模块向负载供电。测试结果显示：采用双电源供电的节点工作周期长于单电源节点，且系统能稳定输出水质监测节点需要±12，±5，3.3 V的电压要求，实现了预期设计目标。

| Abstract: | Design and realize a new type of node double power supply system,which combined with solar cells and lithium-ion battery-powered in order to solve the problem of battery-powered wireless sensor networks( WSNs) node power is constrained. The design adopts IAP15F2K612S2 low power consumption chip and solar panel, lithium-ion batteries powered by software to optimize node power supply,with BQ24650 power management chip realize lithium battery charge control,use IAP15F2K612S2 MCU as microprocessor,monitor discharge of lithium battery voltage and discharge control circuit supply power to load,through DC/DC converter modules. Test results show that work cycle using dual power supply is longer than single source node,and system can stably output ±12,± 5,3. 3 V voltage which water quality monitoring node requires,achieve expected design goals. |
