[Abstract]:Guangxi, located in the south, belongs to a heavy rainfall area, and the occurrence of sudden heavy rainfall is also a necessary condition and direct factor leading to mountain floods and other geological disasters. In the face of the need to prevent such disasters, the local meteorological departments put forward the following requirements. That is, by increasing the spatial density of the automatic observation station, the ability of service, receiving and processing data can be improved, and the forecast of precipitation can be completed in a short time. The paper elaborates the data flow of the local automatic weather station, and probes into the existing problems. After the current data collection, there is no uniform standard, which makes the professionals unable to deal with the data. Carry out deep application and development work. According to the application requirements and the current situation of the local meteorological application service department, a set of systems including format check, data acquisition, merging and quality control are developed for the processing of observation data, and combined with the processed data. Improve the business process, make the automatic station in the data to the final application of the time to shorten, but also let the whole process monitoring goal can be achieved, to ensure that the duty personnel can easily complete the software operation, The monitoring and analysis of the data flow can form the quality analysis result more accurately, and provide the basic data for the forecaster to carry out the analysis work more accurately. Therefore, it is necessary to carry out research and development of a data processing system in front of an automatic station, which can be deployed in districts, cities and counties. The system takes the linux system as the running platform, builds the Oracle database as the storage medium, and the Java technology framework as the premise of the research and development. With the full use of the cross-platform feature, the cross-platform support can be realized on the system. In order to meet the increasing demand of geometric series in the future, multithreading and code encapsulation modularization design is adopted as the key support of data processing in the system. Four independent thread modules are planned for different data processing contents. Each thread carries on concurrent processing and operation to the data under its jurisdiction, such as data collection, checking format, merging and packing, uploading data, archiving log, etc. The high efficiency processing mechanism of multi-thread makes this system can make the classical temperature, humidity, wind, and so on. The data quality control of meteorological elements such as pressure is embedded in the system, taking into account the two key services of data transmission and data local quality control decoding, which greatly improves the processing efficiency and ensures the efficient transmission of data. At the same time, provide high reliability and high availability of real-time data, scientific research projects to provide data support. The threads of the system are independent of each other, and the code module can be reused and encapsulated as an interface, which has good expansibility and lays the foundation for the integration of similar business processes.
