Technical field

The present invention relates to a kind of weather radar networking data processing method, especially a kind of X-band weather radar group netting index According to processing method.

Background technique

Strong convective weather includes short-time strong rainfall, thunderstorm gale, hail, thunder and lightning, spout etc., be it is a kind of it is fast-growth, The high influence diastrous weather that local is strong, destructiveness is big.Weather radar can observe strong convection system by transmitting electromagnetic wave The interior three-dimensional structure and Characteristics of Evolution of system are that current strong convection monitors most effective means.And current China New Generation Weather Radar Average headway is up to 200 km between traffic observation net radar, by earth curvature, electromagnetic wave beam with range spread and terrain shading Deng influence, for low layer (< 1 km height) coverage rate less than 20%, limit strong convection is occurred it is closely related The detection of low-level feature.

In view of the above-mentioned problems, developed countries are paid much attention to promote traffic observation net and Development of Urban region tool in recent years Have fast adaptability scan capability X wave band dual-polarization short distance network radar (radar detection radius 30-40km, radar it Between standoff distance average out to 25km), make up the deficiency of existing radar fence bottomside sounding ability, and provide the sight of Cloud microphysical structure It surveys.The U.S. establishes in about 7000 square kilometres of the southwest Oklahoma area by four small-sized X waves during 2007-2010 Section polarization Doppler Weather Radar networking carries out spring test, in the typical calamity such as spout, strong wind or sudden flood threat Good effect is obtained in the observation and analysis of evil property weather.Japan also establishes in Tokyo metropolitan areas by 7 X waves within 2008 Section radar fence (3 polarizations and 4 Doppler radars), is monitored city strong convection.In Europe, Denmark, Italy, France etc. has also successively carried out the research of the small radar network composite of urban area X-band.

China starts late to the research of X-band weather radar networking, and development is very fast.China Meteorological Administration was in 2008 The work of Meteorological Field scientific research special " distributed all solid state network Weather radar system key technology research ", it is strong right to promote The monitoring and forecast of stream.(plan) mostly to carry out in Beijing, Shanghai, Chengdu, Guangzhou, Foshan, Zhuhai, Yancheng etc. in recent years The construction of X-band Weather Radar Network.

Although the construction of X-band Weather Radar Network is very fast, relevant service software system is also rested on traditional mode. Traditional mode carries out volume scan using radar, is then transferred to central station by FTP after generation base data compressing file, then Central station processing software is based on base data and carries out quality control and product generation.X-band weather radar is carried out at present carries out networking It is all Dual-Polarized Doppler Weather Radar that the radar of observation is most of, and data volume is big, quality control process is more, data transmission and Quality control time consumption is big, carries out the generation of product again later and shows application.Existing hysteresis quality is larger, this is unfavorable for body Existing X-band radar net is fine, the business advantage such as quickly, is unfavorable for the monitoring, early warning and forecast work of strong convective weather.

Summary of the invention

In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a kind of X-band weather thunders Up to networking data processing method, which has access to multi-section X-band weather radar, And it is raw to carry out data receiver, data quality control, volumetric scan data generation, single Radar Products generation and radar network product At.

In order to solve the above technical problems, the technical solution adopted by the present invention is that:

A kind of X-band weather radar networking data processing method, includes the following steps.

Step 1, X-band weather radar networking data processing system is established: X-band weather radar networking data processing system Including multi-section X-band weather radar and the central station X-band weather thunder being connected by network with every X-band weather radar Up to networking data processing system;Central station X-band weather radar networking data processing system includes data reception module, quality control Molding block, volumetric scan data generation module and product generation module;Wherein, data reception module and volumetric scan data generate Module all has data buffer area.

Step 2, volume scan: every X-band weather radar sweeps pattern synchronization according to setting body and starts volume scan, together When, the radial data that scanning obtains is real-time transmitted to central station X-band weather radar networking data processing system as unit of root System;Wherein, radial data includes observation data and status information.

Step 3, data receiver: the data reception module in central station X-band weather radar networking data processing system is real When the radial data transmitted of receiving step 2, and be stored in its data buffer area;When data reception module receives wherein one It, can be by corresponding X-band day after 360 radial datas of single layer and single sweep operation completion status flag information of X-band weather radar 360 root diameter of respective layer of gas radar is passed to quality control module to data copy;Meanwhile corresponding data buffer area is emptied, it is quasi- The standby radial data for receiving and storing next elevation angle.

Step 4, quality controls: after quality control module receives 360 incoming radial datas, calling corresponding X in time The quality-controlling parameters of wave band weather radar carry out quality control;And the radial data after controlling quality is transmitted to volume and sweeps Retouch data generation module.

Step 5, quality controls base data file generated: every X-band that volumetric scan data generation module will receive Radial data after the quality control of weather radar is put into corresponding data buffer area into storage;When receiving corresponding X-band day It, can be corresponding by X-band weather radar after status flag information is completed in all layers of radial data and the single volume scanning of gas radar All layers of radial data generate quality control base data file, and by the quality of generation control base data file be transmitted to product Generation module;Meanwhile corresponding data buffer area being emptied.

Step 6, product generates: received quality is controlled base data file by product generation module, is generated and X-band weather The corresponding product of radar and radar network product.

In step 1, every X-band weather radar is connected with central station X-band weather radar networking data processing system The bandwidth of the network connect is not less than 100M.

In step 6, received quality is controlled base data file by product generation module, using the working method of multithreading, Generate product corresponding with X-band weather radar.

Radial data is PPI radial data or RHI radial data.

Status information in step 2 includes orientation, the elevation angle, single sweep operation end mark and single volume end of scan mark Will.

It is VCP21, VCP11 or self-defined pattern that body in step 2, which sweeps mode,.

The invention has the following beneficial effects: the times that can be shortened X-band day Transmission System of Radar Data, quality control, improve The timeliness that data are generated from radar terminal to product and user uses is monitoring, early warning and the forecast work of strong convective weather Bring many convenience.
