船基气象定线水文气象资料的接收与自动读取

Automatic Collection of Hydrographical and Meteorological Data on board for the Ship-based Weather Routing

本文简要介绍了短波气象定频接收机与ＰＣ机之间的接口卡电路，将此卡插入ＰＣ机扩展槽后，与气象传真接收机相连即可将气象传真图直接收入ＰＣ机中保存，然后提出了一系列气象传真图图象处理技术、主要是针对自动提取高空５００ｈｐａ等压面上的纬向数据，计算５００ｈｐａ西风环流指数。

This paper presents a interface card between the facsimile receiver and the personal computer, it can be pluged in the expansion slot of the PC to connect with the facsimile toreceive the weather prognosis charts and store in The hard disc of the PC. A series of image proccesing technique for weather prognosis charts be proposed, which is, mainly, in accordance with automatic extraction the latitude data on the 500hpa surface of constant pressure to calculate the 500hpa western circulation indexes.
