水力模拟云平台HydroMP的模型集成方法

Model integration methods in the hydro- modeling platform (HydroMP) based on cloud computing

实现动态的模型集成与管理是水力模拟云平台HydroMP建设的关键需求,其关键技术包括平台对模型的驱动、平台与模型的数据交换、平台对模型运行的实时控制以及平台对模型的动态管理。为实现水力模拟云平台中不同类型模型的集成,以满足不同用户的需求,设计了具有通用性和"热插拔"的模型集成方法。提出了不改变模型程序原有运行方式的可执行程序(EXE)集成方法和实现模型进程与平台实时通信的可交互集成方法。EXE集成方法无须更改源代码,只需开发数据转换文件即可实现模型集成;可交互集成方法采用标准通信接口程序对模型组件进行封装并生成新的模型程序,然后在平台中注册实现模型集成,可交互集成的模型进程在运行过程中能与云平台实时通信及数据交换。将两种集成方法应用于水动力模拟云平台(HydroMP),实现了不同类型遗产模型的动态集成和管理。

The dynamic integration and management of models are key demands in the construction of the hydro-modeling platform(HydroMP).The corresponding key technologies include a driving model for the platform,data exchange between the model and the platform,real-time control of the model operation and dynamic management of the models.General model integration methods supporting hot-plug modules are used to integrate different types of models into the HydroMP and to meet the needs of different users.An EXE integration method is developed that does not require changes in the existing running mode of the model programs.There is no need to rewrite the original code to realize the model integration using the EXE integration method;only data conversion modules are needed.An interactive integration method is developed that gives real-time communication between model processes and the platform.This interactive integration approach uses a standard communication program to encapsulate the model and generate a new model program.Then,the new model is registered in the platform to realize the model integration and management.The interactive integrated model process provides real-time communication and data exchange with the cloud platform.These two integration methods are applied to the HydroMP to provide dynamic integration and management of different heritage models.
