Description
Technical field
The present invention relates to the method for transformation of a kind of model towards wireless sense network to code; Mainly be to set up the mapping ruler of model to code; Utilize the visitor to visit model and realize transforming, belong to wireless sense network, soft project, model-driven and code and generate the interleaving techniques application.
Background technology
Wireless sense network is made up of the sensor node that is deployed in the monitored area; The ad hoc network system of a multi-hop that forms through communication; Purpose is an object information in cooperation ground perception, collection, the processing network's coverage area, and sends to the observer.Sensor node is made up of sensor assembly, processor module, wireless communication module and energy supply module four parts, and sensor assembly is responsible for the collection and the data-switching of monitored area internal information; Processor module is responsible for controlling the operation of whole sensor node, data and other node data sent that storage and processing itself are gathered; Wireless communication module is responsible for carrying out radio communication with other sensor nodes, exchange control messages and transmitting-receiving image data; The energy supply module is that sensor node provides the operation energy needed, uses minicell usually.Wireless sense network is brand-new developing direction in the information science field, simultaneously also is new branch of science and traditional subject carries out the result of intersecting between the field.Wireless sense network then is incorporated into network technology in the wireless intelligence sensor; Make that sensor no longer is single perception unit; But can exchange message, coordinate the organic combination of control; Realize the interconnected of thing and thing, go deep into each corner, the world to the perception feeler, will become the important component part of Next Generation Internet.
Based on the characteristics and the application demand of wireless sense network, it is an event driven operating system that designs for sensor network nodes that the TinyOS of Berkeley University's exploitation is one, and sensor network nodes has very Limited resources.For satisfying the requirement of wireless sense network, the researchist introduces 4 kinds of technology in TinyOS: light thread, active message, event-driven and modularization programming.Light thread mainly is possibly compare frequently to the node concurrent operations, and thread is shorter, and the problem that traditional process/thread scheduling can't be satisfied proposes.It designs based on the structuring notion that embodies TinyOS and execution model.Its adopts the framework mode of assembly, structure height modularization, and can break through the various restrictions of sensor node, and the various application of Rapid Realization are fit to the application of wireless sense network very much, thereby are widely used and become the reference design of a lot of systems.The Component Gallery of TinyOS comprises procotol, Distributed Services, sensor drive and data acquisition tools etc., and no assembly can not be introduced into, thereby reaches the purpose that reduces memory requirements.TinyOS has adopted event-based model, can in very little space, handle high concurrent event like this, and can reach purpose of energy saving.TinyOS is the operating system that designs to the sensor network characteristics specially.TinyOS uses efficiently based on the executive mode of incident, comprises the establishment model through particular design, thereby becomes high efficiency modularization and the assembly type application software that is easy to construct.
In TinyOS, the Application developer can be through the incident/command interface between NesC language performance assembly and the assembly.NesC mainly is used among the TinyOS, and TinyOS also writes completion by NesC.NesC is the expansion to C, is mainly used in the programming development of sensor network.TinyOS operating system provides an excellent user interface for the user exactly.Assembly is divided into configuration file and module, and the flow process of program is that the connection through interface in the configuration file realizes making up up, and the logic function of concrete realization is accomplished through module.Each module is made up of Management Information Base and incident, and these orders and incident become the interface of this module.In general, upper component says the word to lower layer components, the generation of lower layer components signaling incident, and the assembly of the bottom is direct and hardware is mutual, thereby forms a kind of tree structure from top to bottom.
Simultaneously, UML also is widely used in the wireless sense network exploitation very much.UML, UML can provide a kind of language of visual modeling for software systems.In development system product process, can furnish an explanation for system product, function such as visual and Edit Document.The UML modeling method is a kind of standard modeling of having summed up the experience of modeling technique in the past and having absorbed current outstanding achievement.UML comprises semanteme, representation and the explanation of notion, provide static, dynamically, the model of system environments and institutional framework.It is for supporting most of existing object-oriented development process to design.UML has been described the static structure and the dynamic behaviour of a system, and it is some discrete interactional objects and the final model structure that certain function is provided for external user with system description.Static structure has defined the attribute of important object and the mutual relationship between operation and these objects in the system; Dynamic behaviour defined object the time ask that characteristic and object are for accomplishing the mechanism that target communicates each other.UML also comprises the construction package that can model be resolved into bag, so that software group becomes easy-to-handle block structure with big system decomposition, and understands and controls the dependence between each bag, administrative model unit in the development environment of complicacy.It also comprises the assembly that is used for display system realization and operation.In the wireless sense network exploitation, extensively adopt the NesC language, and NesC is mainly used in also among the TinyOS, on stream, popular a kind of mode is converted into object code with related software with model then for setting up model earlier.
Model has extensively been sent out to the transformation technology of code and has been applied in the project exploitation, and the model-driven exploitation is a kind of development approach very important in the software development methodology, has plurality of advantages, is well suited for the sensor network Development of Software.The platform of a good model-driven exploitation has determined whether this development model can be promoted and can provide the development efficiency of sensor network.By the UML UML that has reached its maturity, the entire software development process is with reference to OO software development methodology.Comprise processes such as demand analysis, summary design, detailed design.In conjunction with the characteristics of sensing net software development, the advantage of sensing net software development methodology is analysis modeling sensing net preferably, auxiliary large-scale sensing net software development.This model can be analyzed the sensing net activity that foundation is unit with the group, clearly makes up the architectural model of extensive sensing net software.This intelligence body can self-organization set up the sensing net, independent arbitration decision factum, participating in the group is the various intelligent body group activity of unit.This sensing net software development methodology makes and sensing net software development modelization has improved sensing net software development efficiency, reduced the difficulty of sensing net software development.
The automatic generation technique of code has become an indispensable technical ability of project exploitation, and it reduces the development amount and prevent that defective from producing through generating the mode of text automatically.Code generation based on model is the key areas of current soft project research.Be directly changed into the unitarity that source code can make this maintenance of exploitation design a model and realize from model, reduce the workload of writing code, improve the speed and the quality of software development.
Traditional code generates, and the repeated code that at first often occurs in the recognition application source code generates the object code that these repeating parts replace hand-coding then automatically; So-called object code is meant and uses relevant a series of products, for example document; Script, defined file etc.If there is not the code Core Generator, the developer can obtain the dirigibility high product although it is so with all codes of Hand writing, still, uses the automatic generation of code to reduce cost, and reduces error rate, makes reliability stronger.
