Abstract

Abstract

As an application platform of provincial meteorological service, the operational system of provincial meteorological instrument calibration is applied to improve professional management, working efficiency and calibration quality. This system consists of two parts: The management subsystem and automatic calibration subsystem. With B/S construction and the classic C/S structure technology adopted respectively in the two subsystems, the operational system brings digitization, and automation of calibrating into effect. In detail, the management subsystem is combined with the module of data receiving and distributing through apparatus, instrument maintenance, system management, warning inspection beforehand, report form processing, comprehensive inquiry and statistics, and administrative control of measuring instruments. The automatic calibration subsystem includes the automatic detection of temperature, humidity, pressure, wind and precipitation sensors, which can carry out automatic calibration and performs intelligently in data processing. On the whole, the application of this system shows that the calibration efficiency and quality have been significantly improved.
