For the power supply problem of forest orchard wireless sensor network environment monitoring system in complex environments,this paper proposed and designed a photovoltaic and wind power supply system which has high reliability and stability. The system can charge the super capacitors and lithium ion battery pack with solar cells,a miniature wind power generator or an external DC input. In response to the complex weather conditions of the orchard,the three level of high sensitive protection circuit can be a good protection of the power supply system. The lithium ion battery pack is protected by the wireless microcontroller CC1310. According to the preset discharge priority,select one of the super capacitor group,the lithium ion battery or external DC power supply to provide power for the wireless sensor network monitoring node. The test result shows that this design the stability of the 5V and 3. 3V output in this design is as high as 99. 6% and 99. 4% respectively,it can supply a stable energy security for most of forest orchards wireless sensor network monitoring.
