Breath loop module is designed using Observer Pattern；Observer Pattern (Model-View (View) mode that is otherwise known as sometimes,
Source-listener (Listener) mode or subordinate's mode) be software design pattern one kind.In such mode, a mesh
Mark object manages all observer's objects for depending upon it, and actively gives notice when the state of itself changes.This is logical
Often realized through method provided by each observer is called.Such mode is usually used to realization event handling system.Observation
Person's mode (Observer) perfectly separates observer and observed object.For example, user interface can be used as
One observer, business datum are observed persons, and the variation of user interface observed traffic data is just aobvious after finding data variation
Show on interface.One principle of Object-Oriented Design is: each class in system focuses on some functionally, without
It is other aspects.One object only does something, and he is carried out.Observer Pattern delimited clearly between the modules
Boundary improves the maintainability and reusability of application program.One kind that observer's design pattern defines between object is one-to-many
Syntagmatic, when changing so as to the state of an object, all objects dependent on it are all notified and brush automatically
Newly.
The Component Gallery provides function program interface for carrying all functional objects；Component library module is exactly all
The carrier that function is realized, it is made of one or more Component Gallery.It can be by the functional realization of institute in the same library
Different function can also be combined with each other in different Component Galleries by face.Function (Command) object in Component Gallery passes through expansion
Exhibition factory is created out, in local calling function (Command) interface of needs.Program can add according to their needs
Different Component Galleries is carried, different demands is realized by way of component combines to reach with this.Its core meaning is generation
Code multiplexing.Function is relatively single or independent, upper in the bottom in the code level of whole system, by other codes institute according to
Rely.Its core meaning is to separate responsibility.Its focus is function division.Traditional development scheme low efficiency and maintenance
The main reason at high cost, is it is many times that a system has been made into monolith application, and often with the growth of business
Or change, the complexity of system can growth exponentially, it is often the case that be exactly a slight change or
The increase of one small function may cause the modification of overall logic, cause to pull one hair and move the whole body.It is desirable that it is one big and
Complicated scene can be broken down into several small parts, these small parts are not interfere with each other each other, can individually develop,
It separately maintains, and can be arbitrarily combined between them.Multiplexing factory mould is in the extension factory used in the present embodiment
Formula, the purpose of more factory modes are to improve the clarity of code structure, and the creation of every kind of product is allowed to correspond to a special factory
Class, we are not necessarily to Transfer Parameters when creating object in this way, but product can be created by calling directly corresponding factory,
The responsibility of factory class is apparent.
The system configuration module is used to obtain the total interface of whole system, the interface include GNSS resolve interface,
Interface engine interface, function program interface and message loop interface.System configuration module belongs to housekeeping roles, can be obtained by it
Obtain whole system total interface, it is only necessary to the interface of the module is passed to each function and realize class.System configuration mould
Block base class includes the general basic interface that program needs, for example data flow read-write interface, message loop interface, interface engine connect
Mouth, log interface, soft ware authorization interface etc..Specific procedure needs to extend other interfaces, such as coordinate system interface, layer management
Interface etc. can instantiate oneself distinctive system module by inheritance system configuration module base class.Finally use when
It waits, startup program, shows program main interface.

Property, expansibility.Present invention employs extension plant technology, observer's design pattern, by whole system be abstracted as system administration,
Interface engine, functional unit library.By each function modeling become order (Command) object, the object with whether
It can be seen that, the attributes such as whether available, title, icon and the method for executing the function.
It extends plant technology: only needing simple registration target object, it can be when needing to create target object by not
Same parameter calls factory method to create object, and target object is not necessarily to and factory method is in the same library file.Observation
Person's mode: a target piece manages all observer's objects for depending on it, and actively issues when itself state changes
Notice, and the notice that observer's object receives target piece sending makes corresponding movement later.
