Description

Technical Field

[0001] The present invention relates to the field of model simulation technology, and in particular to a simulation system and method based on a network service simulation model. Background Art

[0002] The most fundamental components of a simulation system are the simulation model and the simulation engine. The simulation model is an abstraction of real-world objects. For example, a radar simulation model simulates the functions and performance of real-world radar equipment. The simulation engine drives the simulation model and provides services such as data exchange. The simulation model, simulation engine, and other simulation support tools together constitute the simulation system, providing simulation services for upper-layer applications.

[0003] Traditional simulation models are typically packaged as libraries (.lib static libraries and .dll dynamic libraries on Windows, and .a static libraries and .so dynamic libraries on Linux) for loading and calling by simulation engines. The simulation model library must be deployed on the same compute node as the simulation engine. This library approach has the following disadvantages: First, simulation model library management is complex, requiring copies to multiple locations and making model library version management difficult. Second, it is inconvenient for model reuse. If different simulation engines want to call the same simulation model library, they must copy the library to each engine's directory. Third, it lacks support for remote calls. The simulation model library can only be called by the local simulation engine, not by other simulation engines on the network. Fourth, it cannot quickly respond to simulation application requirements. When simulation application requirements change, the simulation model library must be manually configured and deployed, preventing flexible organization of the library to quickly build new simulation applications. Fifth, it lacks support for cross-platform and cross-language calls. To support cross-platform calls, a simulation model library must recompile its source code on the target operating system. To support cross-language calls, it must adhere to more complex cross-language calling conventions. Summary of the Invention

The simulation model network service and the simulation engine are based on the same simulation model network service interface specification. Therefore, no matter what platform the simulation model network service is on or what language it is implemented in, it can be called by a simulation engine developed on any platform and in any language.

[0127] Example 3

[0128] In view of the shortcomings of simulation systems based on library-based simulation models, encapsulating simulation models as network services has the following advantages: First, it facilitates the reuse of simulation models, and network service-based simulation models can be directly accessed and called by different simulation engines in the network; second, it facilitates simulation model version management, and the versions of different simulation model network services can be reflected in the network interface; third, as a network service, it naturally supports local and remote access; fourth, it can quickly respond to simulation application requirements. When the simulation application requirements change, there is no need to reconfigure and deploy the simulation model library, and the simulation model service can be flexibly switched according to the simulation application requirements; fifth, it supports cross-platform and cross-language calls. The simulation model network service and the simulation engine are based on the same simulation model network service interface specification. Therefore, no matter what platform the simulation model network service is on or what language it is implemented in, it can be called by simulation engines developed on any platform and in any language.

[0129] The simulation system based on the network service-oriented simulation model in this embodiment includes three parts: a simulation engine, a network service infrastructure, and a network service-oriented simulation model.

[0130] The simulation engine is used to drive the operation of simulation models and provide model solving services for other simulation applications. The simulation models scheduled by the simulation engine include internal models and proxy models. The internal model is the original simulation model inside the engine, and the proxy model is a simulation model specially developed for calling network service simulation models. The proxy model complies with the model interface specification of the simulation engine. From the perspective of the simulation engine, it is exactly the same as other internal simulation models. The internal model and the proxy model interact through the internal communication mechanism provided by the simulation engine.

[0131] The network service infrastructure is used to provide functions such as network service registration, service positioning and service discovery, and is generally implemented using open source network middleware such as ICE (Internet Communications Engine), DDS and ZMQ.

[0132] The network service simulation model provides a specific network simulation model implementation. Its internal structure is a simulation model implemented in the user's preferred method and development language. It is then encapsulated as a network service simulation model according to the specifications of the network service infrastructure, thereby providing the function of network remote calling. In particular, a network service simulation model can realize its simulation function by calling other network service simulation models.

[0133] The process of developing a simulation system based on a network service-oriented simulation model is as follows:

[0134] The first step is to implement the simulation model in the way the user prefers and in the development language they are good at.

[0135] The second step is to encapsulate the above model into a network service simulation model according to the specifications of the network service infrastructure;

[0136] The third step is to register the above network service simulation model with the network service infrastructure;

[0137] The fourth step is to develop a proxy model for the corresponding network service simulation model according to the packaging specifications of the simulation engine;

[0138] In the fifth step, the proxy model obtains the service interface of the network service simulation model during the initialization phase;

[0139] Step 6: During the simulation process, the simulation engine schedules the operation interface of the internal model and the proxy model;

[0140] In the seventh step, when the running interface is called, the proxy model obtains the output of the internal model and other proxy models through the internal communication mechanism of the simulation engine, and uses it as input to call the service interface of the network service simulation model. After the scheduling is completed, the output of the network service simulation model is obtained, and then the output of the network service simulation model is sent to the internal model and other proxy models through the internal communication mechanism of the simulation engine, thereby realizing the collaborative simulation of the internal simulation model and the external network service simulation model. The input and output relationship and scheduling order of the internal model, proxy model and network service simulation model are as follows: Figure 3 shown.

Some or all of the modules may be selected based on actual needs to achieve the objectives of the present embodiment. Persons of ordinary skill in the art will be able to understand and implement the present invention without inventive effort.
