Embodiment 1

[0040] A decentralized micro-service regional flood warning information system, including six parts: data collection layer, data integration layer, micro-service layer, service registration center cluster, API Gateway cluster, and end-user layer.

[0041] 1. The data acquisition layer: collect real-time water information data monitored by various sensors through the Internet of Things, the Internet and mobile communication technologies, and store them persistently in the database of the data integration layer.

[0042] 2. The data integration layer: a hybrid database including a relational database and a non-relational database, through which the hybrid database defines and persistently stores four types of data support establishment: user management data, real-time water information data, model information data, and spatial data Flood warning model and flood submergence map display function; the user management data includes user name, password, authorization authority data (a...

Embodiment 2

[0054] The integration method of the decentralized micro-service regional flood warning information system based on embodiment 1 includes the following working steps:

[0055] 1. Acquisition and processing of real-time water information data: realized by a data acquisition and processing device, the data acquisition and processing device includes three parts: a task grabber, a task scheduler and an ETL server; the task grabber captures real-time The water information data is uploaded to the data processing microservice in the microservice layer; the data processing microservice uses the distributed Pipe technology ETL server to transmit massive real-time data, and implements different Interceptors in the Pipe for data cleaning and assimilation processing; finally The data is stored in the non-relational database of the data integration layer, which can be used for flood warning microservices and flood map display microservices to support user interactive real-time query; the ta...

Embodiment 3

[0062] The method can be embodied in many different forms in combination with specific regions, and is applied in the watershed above Wangjiaba of the Huaihe River or the watershed above the Danjiang Estuary of the Yangtze River.

[0063] Examples such as figure 1 , figure 2 , where the data acquisition layer includes real-time water information (water level, flow, rainfall) data stored by three CASSANDRA database nodes, three HBASE database nodes store watershed DEM terrain data, and one PostgresSQL database stores administrative boundaries, meteorological stations, and hydrological stations Space vector data and 1 Mysql database store user authority data, system configuration data and model parameter data; the data integration layer includes 2 server nodes to deploy data collectors; the microservice layer includes 6 server nodes, each of which is a flood warning microservice Nodes, 1 flood display micro-service node, 1 data engine micro-service node, 1 user authority micro...

Abstract

The invention discloses a decentralized flood early warning information system for a micro-service area and an integration method thereof. The system comprehensively organizes functions of data acquisition and processing, machine learning flood early warning, flood inundation map display and the like, and comprises a data acquisition layer, a data integration layer, a micro-service layer, a service registration center cluster, an API Gateway cluster and a terminal user layer. The method has relatively strong system fault-tolerant capability and reliability; and the system application is expanded and evolved into fine-grained service expansion, the programming language selection range is wide, deployment is simplified, real-time water information data, model simulation analysis and result visualization can be integrated, and then the instant flood inundation range and depth information based on a GIS map are provided for a decision maker.

Description

technical field [0001] The invention relates to the technical field of flood early warning, in particular to a decentralized micro-service regional flood early warning information system and its integration method Background technique [0002] In recent decades, with climate change, the degree and scale of flood disasters have increased dramatically. Large-scale flash floods have brought fast-flowing and rising water resources to the world, causing huge loss of life and property and social destruction. Real-time access, analytical processing, and interactive visualization are critical to better understanding flood-related issues. [0003] With the advancement of science and technology such as the Internet of Things, Internet technology, and mobile communications, a large amount of real-time water information data has been obtained, including remote sensing data, meteorological data, rainfall data, water level data, water flow data, and various camera terminals and mobile ter...
