摘要：

为了有效弥补传统山火监测方法的不足,准确研判火场发展态势,将新一代气象雷达应用于山火监测中,开辟了火灾监测新领域。该气象雷达能对周边120 km范围内的地形环境进行扫描,基于多普勒原理技术对着火点进行判别与判定,能在火灾发生后6 min内迅速识别着火点经纬度坐标,同时开发出手机客户端APP软件,当接收到雷达系统传送来的着火点经纬度时,软件检索查询出着火点附近一定范围内的杆塔和护线员、线路巡视人员,并能及时根据预警信息进行应对处理。同时,该雷达探测对闷烧型火灾的监测效果比其他方法要好,具有全天候监测、监测连续性好、发现早、预警早、定位更精准等特点,更能检测到其他监测系统不能预警的火灾。案例表明,在清明节、冬季等山火易发时节,该应用极大地促进了山火防治工作,有助于减少因山火造成的跳闸事故。

Abstract:

To effectively make up for the inadequacy of traditional fire monitoring method, and accurately analyze fire development situation, a new generation of weather radar is applied in fire monitoring, and it will open up a new field of fire monitoring. The weather radar can scan the scope of the terrain environment around 120 km. On the basis of the principle of Doppler technology criterion of ignition, the weather radar can quickly identify latitude and longitude coordinates after the fire ignition in six minutes. A mobile client APP is developed. When the APP receive the ignition of the latitude and longitude which are transmitted from radar system, the software searches and sinds that the line patrol personnel of the pole tower and the line guard within a certain range near the fire point who could respond to the early warning information in a timely manner. At the same time, the radar to detect the smoldering fire monitoring effect is better than other methods. It has good all-weather monitoring, monitoring of continuity, found early, early warning and more accurate positioning, and it can detects more fire that other monitoring system can’t early warning of fire. The application case shows that in the Qingming festival, winter and other vulnerable mountain fires, the work of mountain fires prevention and control is greatly promoted, which is helpful to reduce the number of jumping accidents caused by mountain fires.
