Description

A kind of implementation method of Model and experiment framework apart

Technical field

The present invention relates to a kind of implementation method of model, particularly a kind of implementation method of Model and experiment framework apart.

Background technology

Emulation is the activity based on model, and the implementation method of model has larger impact for the availability of analogue system.Model is separated with experimental framework is a kind of advanced person's system modeling method, in the method, the dynamic and static characteristics of model determination system, experimental framework is determined the experiment condition that makes model running and produce output.To given system model, can have a plurality of experimental frameworks, thereby realization is not in the situation that revising model, only revises experimental framework and completes different emulation experiments, thereby greatly promotes the use dirigibility of analogue system.But current existing implementation method operation is loaded down with trivial details, and speed is slower, is therefore badly in need of a kind of new implementation method.

Summary of the invention

The object of the invention is to provide a kind of implementation method of Model and experiment framework apart, to solve during analogue system realizes, due to model and experiment parameter coupling closely, affect the problem of analogue system use dirigibility.

Object of the present invention is achieved through the following technical solutions:

An implementation method for Model and experiment framework apart, is characterized in that, this implementation method comprises the steps:

1) build for the implementation model system separated with experimental framework;

2) model realization formwork module generation model code;

3) experimental framework describing module generates experimental framework description document;

4) link block completes the coupling of model realization and experimental framework;

5) experiment initialization module completes the initialization that model is carried out.

The invention has the advantages that:

The implementation method of Model and experiment framework apart of the present invention makes system operation more convenient.

Embodiment

The implementation method process flow diagram that is illustrated in figure 1 a kind of Model and experiment framework apart, this implementation method comprises the steps.

The first step builds the system that realizes the method

For the implementation model system separated with experimental framework, comprising: model realization formwork module, experimental framework describing module, link block, experiment initialization module.

The function of model realization formwork module is: standard interface implementation model example is provided, provides the experiment parameter relevant to model scheduled for executing that interface is set;

The function of experimental framework describing module is: the experiment parameter constraint that supplies a model and carry out, comprises simulation run control information, Model instantiation information, model running initial state information, Experiment Data Records and process information etc.;

The function of link block is: by model identification, complete the coupling of model realization module and appointment experimental framework;

The function of experiment initialization module is: complete Model instantiation, initialization, complete experiment parameter setting.

Second step model realization formwork module generation model code

Model realization formwork module restricted model code, to provide as lower interface:

Instantiation interface: according to parameter generation model examples such as types of models, times;

Input port: complete the definition of the input external interface of model;

Output port: complete the definition of model output interface;

Initialization port: complete the definition of model initialization parameter, provide with binary stream form, by model self-explanatory;

Control interface: complete the setting of controlling parameter in model implementation, control that parameter comprises startup, suspends, continues, stops, Experiment Data Records etc.

The 3rd step experimental framework describing module generates experimental framework description document

Experimental framework describing module generates experimental framework description document, and the experimental framework of generation comprises following information:

Simulation run control information, as simulation time, number of run etc.;

The instantiation information of model, comprises example creation-time, example creation-time interval (fixed value or stochastic distribution), (quantity once generating) etc. in batches;

Initialization information, the information of the initialization port bookbinding of Definition Model;

Port observation and Data-Statistics information, the port value that will gather in definition simulation process, and value is added up to computation of mean values, variance, confidence interval etc.

Experimental framework description document adopts and meets XML language description.

The 4th step link block completes the coupling of model realization and experimental framework

Link block travels through the model realization set of analogue system, to each model realization, and the implementation framework information that is identified at match query in experimental framework set by it, basic procedure is:

In model realization set, start traversal, obtain a model realization

According to model identification, in experimental framework set, inquire about, whether there is the experimental framework definition of coupling, if do not had, return to previous step

According to the experimental framework inquiring, determine the instantiation form of model, if in batches, build Mass production data structure, if individual, build and generate chained list

Whether according to the experimental framework inquiring, checking has the initialization information of bookbinding, if had, batch data structure or individual generate chained list in assignment

According to the experimental framework inquiring, whether check ports having observation and statistical information, if had, the set handling parameter in model realization code

The 5th step experiment initialization module completes the initialization that model is carried out

The treatment scheme of experiment initialization module:

Output interface definition according to model realization code, builds output database;

Traversal model realization set and experimental framework set, whether inspection model code provides specified interface, and whether the setting of checking experiment framework parameter is reasonable;

Simulation run is set and controls parameter, comprise working time, number of run, process record sign etc.;

According to experimental framework definition, complete the scheduling chained list initialization of Model instantiation.
