Embodiment 1

[0038] Combine below figure 1 , the present invention is further described:

[0039] The technical solution adopted in this embodiment is to excavate the abnormal values ​​in the national automatic observation stations, and use the "static weight + dynamic interpolation" method to improve the interpolation efficiency and interpolation effect for the rainfall values ​​at the abnormal station locations. Follow the steps below to implement:

[0040] (1) Real-time receiving and processing of reported data from national automatic observation stations: According to the precipitation coding format defined in the "Hydrological Monitoring Data Communication Protocol", analyze the station address, sending time, precipitation, rainfall duration, and cumulative precipitation Value, observation time, power supply voltage and other information, and save to the database.

[0041] (2) Judgment of abnormal value: Realize the judgment of abnormal value through Oracle trigger.

[0042] First,...

Abstract

The invention discloses a hierarchical data processing method for a large-scale real-time rainfall automatic observation station based on dynamic interpolation. The hierarchical data processing methodcomprises the following steps: step 1, receiving and processing reported data of national automatic observation stations in real time; step 2, judging an abnormal value; Step 3, equal time period processing; Step 4, screening and eliminating error values; And 5, performing interpolation calculation on the basin surface rainfall. According to the hierarchical data processing method for the large-scale real-time rainfall automatic observation station based on dynamic interpolation provided by the invention, after abnormal points are found, the abnormal points are interpolated by adopting a 'static weight + dynamic interpolation' method, so that the interpolation efficiency and effect are improved, and the accuracy of rainfall data is improved.

Description

technical field [0001] The invention belongs to the technical field of disaster monitoring and early warning, and in particular relates to a dynamic interpolation-based large-scale real-time rainfall automatic observation station classification data processing method, which is mainly used for mountain torrent simulation, forecast and early warning. Background technique [0002] Ground observation is an important means of realizing weather system monitoring, and an important way of disaster monitoring and early warning. In recent years, wireless sensor technology has brought new development and application to the ground meteorological observation system. The automatic observation station formed by the combination of wireless sensor and ground meteorological observation system makes up for many deficiencies such as low frequency and poor spatial resolution of traditional manual observation. However, the automatic observation station only obtains rainfall at the station, while ...
