After the volume-based file is generated, it will be uploaded to Provincial Meteorological Information Center (PMIC) by file polling, then forwarded to NMIC in the same way. The end-users can only retrieve data after volume scan finished, it’s not suitable for time-critical applications such as nowcasting, moreover file polling and forwarding between transfer nodes will introduce additional delay. In this paper, we propose a technique to reduce the delay introduced by transmission. After radial data is generated by the signal processor, it is sent to the server of PMIC immediately, the server will collect real-time radial data from dozens of sites simultaneously and forward them to the server of NMIC and servers of other agencies as required. In such a scheme, the radial data will be got in less than one-second delay by endusers. Radar base data can be archived in elevation and distributed to applications that need a fast update. The system builds an efficient and stable base data transmission and distribution network, which greatly improves the efficiency of data transmission and applications.","PeriodicalId":257532,"journal":{"name":"2019 International Conference on Meteorology Observations (ICMO)","volume":"276 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121823678","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The software radar signal processing system has become the general trend of research, which is closely related to the meteorological and hydrological application requirements of the current radar system. The signal processor of the CINRAD, as the core part of data acquisition and processing of radar system, directly affects the accuracy of weather process detection. In view of the disadvantages of the traditional digital radar development mode of ‘taking hardware technology as the core and facing special functions, a Doppler weather radar signal processing system based on software design is proposed, which effectively solves the disadvantages of tight coupling of traditional radar hardware design and realizes software and hardware decoupling. Through the modular and loose coupling design, the rapid development of software technology is used to realize the rapid development and design of new functions of software radar signal processing system. The results show that: 1) the engineering software Doppler weather radar signal processing system has the advantages of software, modularization and loose coupling. 2) The software research and development mode can quickly and effectively improve the resource allocation ability of radar signal processing system, quickly realize new demands, and meet the practical needs of rapid development. 3) shorten the research and development cycle and reduce the hardware cost. The software based signal processing system has been widely used in SC and CD weather radar of National Meteorological Administration, and gradually extended to the radar system of civil aviation, hydrology and power grid industry.","PeriodicalId":257532,"journal":{"name":"2019 International Conference on Meteorology Observations (ICMO)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120926366","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The approach adopted by the quality management system standards combines the PDCA cycle with risk-based thinking. This method ensures adequate management and prevention control of ground meteorological observation technology methods, meteorological data operation and monitoring, meteorological equipment and support, meteorological products and services, and can minimize adverse effects. In July 2019, the Liaoning Provincial Meteorological Bureau issued the Liaoning Provincial Quality Management System Document, covering 34 quality documents, 74 operating instructions and 64 records, and started to carry out 4 direct reports in Liaoning Province in August including the internal audit of the meteorological bureau of 51 counties (districts, municipalities). The results of the internal audit of the integrated station indicate that the main risk points of the integrated meteorological observation quality.management system exist and internal and external processes. There are 131 general non-conformities and 374 proposed improvements, mainly corresponding to the quality management procedures 5.3 and 5.4, GB/T19001-2016, 7.1.3 and 8.1.d.
