order to solve the practical demand of herds locator for long working -time, locator with solar complementary charging is designed. The hardware is composed of STM32L151 microprocessor,SIM800L and Air530 Beidou GPS module, and the low power management circuit. The software focuses on the design of a set of low-power work strategy. The experi-ment shows that the locator works stably and reliably,and has a long endurance,which has a high practical value.
