The system can automatically start generator for power supply when municipal electricity is failure; when municipal electricity returns to normal,it automatically restores the power supply function of municipal electricity. In order to improve the stability of the system,the system has the functions of fault alarm,remote reset and remote query,etc.,which can realize seamless switching of municipal electricity and generator. It effectively avoids meteorological data loss,data delay,network interruption,etc. caused by unstable municipal electricity,solves the power supply problem of grass-roots meteorological station,especially at night,provides stable power supply for the integrated meteorological observation,forecasting,and early warning service.展开更多
