Design And Implementation Of Operator Management Subsystem In Big Data Calculation Engine Of Soil And Water Conservation

Soil and water loss poses a serious threat,greatly affecting the economic development of the country and the production and life of the people,so soil and water conservation work is very important.Dynamic monitoring is an effective means of monitoring soil erosion.Through soil erosion equations,soil erosion can be quantitatively calculated,providing a data basis for formulating effective protection measures.The big data calculation engine for soil and water conservation is a platform that supports dynamic monitoring data calculation,abstracting various factor calculations in soil erosion models into operators,thereby completing automatic calculation of soil and water loss.Different types of operators have different functions,and the calculated results are also different.How to efficiently manage operators is of great significance.In order to effectively manage operators,this paper designs a formal structural model of operators based on soil erosion models,encapsulating and abstracting the calculation of factors in big data computing engines,and obtaining operators;The operator configures parameters such as data sources,data input and output formats,and time granularity to meet various parameters during production task calculation;In addition,complex operators composed of multiple operators include data flow and upstream and downstream dependencies,which can better provide computing model solutions to meet business requirements in multiple scenarios.Through analyzing the system requirements,designing the hierarchical architecture of the system,designing the database and API interface according to the functional modules,and conducting relevant tests,the design and implementation of the operator management system has been completed.This system has been implemented and used in the big data calculation engine for water and soil conservation.With the combination of operator management and calculation engine,it has been able to perform efficient,extensible,and automated calculations on operators.The design and implementation of this scheme provides a good solution for the current dynamic monitoring work of water and soil conservation.
