Mobile meteorological measurement field calibration and checking information system

In order to suit the working requirement of field calibration and checking of the automatic weather station, a mobile meteorological measurement field calibration and checking information system was designed. This system is based on visual basic programming language and data base technique, which use serial communication to communicate with the device and use EXCEL and visual basic to design the report form. This system can achieve the auto calibration of the automation weather station's normal collector DT50 and ZQZ-CII,and it can also perform field calibration and checking of temperature, humidity, pressure, rainfall, evaporation, radiation sensor and aero vane. Several experiments are carried out at the district weather station,and the results show that this system can achieve functions such as processing and checking the collected data, saving data into the data base, searching data, printing the calibration qualification,and outputting the data recording form. This experiment verified the effectiveness of our system. This system provides an automatic field calibration and checking software to the meteorological measurement field, which improves the working efficiency and automatic level of the meteorological measurement field. It also ensures the normal function of the automatic weather station and the accurateness of the data.
