The Design and Application of Intelligent Power Supply System of Integrated Meteorological Business at the County Level

The system uses Japanese Mitsubishi PLC as the main control core,and intermediate relay is used for signal acquisition and conversion.The system is mainly composed of data processing module,municipal electricity monitoring module,wireless communication module,remote controller,speech recognition module,display module,sensor,switching output module and UPS power supply. 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.
