摘　　要：主要介绍了如何对省、市气象计量检定部门原来配置的500型风洞检定系统进行升级改造。总体方案和设计思想是以计算机为核心,开发研制数据采集器和电机控制电路将检定过程中的物理量全部数字化,计算机从采集器的串行异步口读入数据,实现自动气象站风速传感器室内检定过程全自动化,同时具备常规测风仪器的半自动检定能力。检定数据传入局域网服务器,实现数据远程处理、打印和共享。软件基于Windows平台,采用VB6.0编写。系统已成功投入使用,一年多的检定实践证明,该系统运行稳定可靠,使用方便,操作简单,计划在全国气象计量检定单位推广应用。The upgrading and reconstructing of the calibrating system based on the Model-500 wind-tunnel used widely in the provincial/prefectural-level meteorological instrument calibration departments is introduced. The overall design scheme and philosophy are based on a computer, and the data collector and motor control circuit are developed to digitize all physical quantity involved in the process of calibration. The computer reads in data from the asynchronous serial port of the collector to realize the automation of AWS （Automatic Weather Station） wind speed sensor calibration and meanwhile to have the capability of calibrating semi-automatically conventional windfinding instruments. The calibration data are put into the LAN server, and the remote processing, printing, and sharing of data are realized. The software is based on the Windows platform written by VB 6.0. This system has been put into operation, and the practice of more than one year proves that it is steady, reliable, and easy to use. The competent authorities plan to popularize the system in the meteorological instrument calibration agencies across China.
