| 摘 要： | 介绍了新开发的极轨气象卫星林火实时监测系统的原理、功能及其数据处理流程.其特点是在卫星过境的同时就可处理出森林火灾信息,解决了目前同类气象卫星林火监测系统不能实时监测的问题.极轨气象卫星林火实时监测系统是由3台计算机组成的并行处理系统.该系统将火点判识的时序从模糊到确定分3步进行,并将数据接收、火点判断、火点定位、显示等的运行时序分配在3台计算机中同步运行.该系统于2005年在广州气象卫星地面站投入业务运行.与原有卫星遥感林火监测系统比较,该系统对森林火灾监测的时间可提早约30 min.

| Abstract: | An introduction is made to the principles, functions and data processing procedures of the newly developed polar orbiting meteorological satellite real time monitoring system of forest fires. This system can process the data of forest fires while a satellite is passing by. It has solved the problem of real time monitoring that many other meteorological satellite monitoring systems cannot handle. The real time monitoring system is a parallel processing system composed of three computers. It divides the time sequence of recognizing a fire site from obscurity to confirmation into three steps, and the time sequences of data receiving, fire site judging, fire site targeting, and displaying are distributed in three computers, which operate synchronously. This system has been put to operational use in the Guangzhou Meteorological Satellite Ground Station since 2005. Compared with the former satellite remote sensing monitoring system, it can monitor and report forest fires 30 minutes earlier. |
