Embodiment Construction

[0028] Such as figure 1 , 2 , 3a, 3b, 3c and 4, the method for monitoring the distribution of rain zones through the microwave link network of the present invention comprises the following steps,

[0029] Step 1, set up the microwave link network topology structure, the network topology design of the microwave link is the basis for utilizing the microwave link to monitor the dynamic distribution of the rain area, and a reasonable network topology has a higher monitoring efficiency. The present invention divides the monitoring area into There are grid areas with m rows and n columns. The shape of the grid area can be set as a square, which is convenient for calculation and division. The row edge of each grid area is a ij and column edge b pq Represent each microwave monitoring link respectively, where, m≥2, n≥2, i=1,2,3,...,m+1, represents the row of the row side of the grid area, j=1,2,3 ,...,n, indicates the column of the row edge of the grid area, p=1,2,3,...,n+1, indicat...

Abstract

The invention provides a method for monitoring rain area distribution by the utilization of a microwave link network. The method includes the steps that a microwave link network topology structure is firstly established; according to the established network topology structure, whether rainfall exists on a microwave monitoring link or not is judged; then according to a judged result, the static state rain area distribution is obtained; finally, according to the sequence of time, rain area motion trails are generated. The method can effectively monitor the rain area distribution in real time, and rain area distribution conditions are convenient to master for a monitoring department in real time.

Description

technical field [0001] The invention provides a method for monitoring the distribution of rain areas, in particular a method for monitoring the distribution of rain areas through a microwave link network. Background technique [0002] Rainfall is an important meteorological factor that affects the natural environment, social life, agricultural production, transportation, aircraft take-off and landing, missile launches, etc. The abnormal temporal and spatial distribution of rainfall often leads to natural disasters such as floods, landslides, mudslides, and urban waterlogging. , bringing serious human and economic losses to our country. [0003] Although rainfall measurement methods such as rain gauges, weather radars, and satellite remote sensing have been widely used, there are extremely complex temporal and spatial changes in rainfall in urban / mountainous areas. Rain gauges have high measurement accuracy, but they require regular maintenance and calibration. The distribut...
