To realize the standardization and automation of meteorological observation equipment’s test and experiment operations, the Test and Experiment System of Meteorological Observation Equipment was designed and implemented directing at conventional ground observation equipment. Based on Web technology and the Oracle database, several functional modules, including process management, data configuration, equipment operation and state management, expert analysis and calculation, data inquiry and display, generation and export of test report and system management, have been realized in the way of flexible configuration, hierarchical design and modular application. It standardized the management of test and experiment operations and improved the work efficiency as well. The results of calculation and evaluation are consistent with those of manual treatment. On this basis, further design and development will be reinforced of the test and experiment platform system appliable to radiosounding equipment, weather radar and other meteorological observation equipment.
