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.
