The research that 1 research setting controls a system domestic and internationally now about opening type and demonstrative application the soft hardware development of PC of with a view to, pledge actually even if the PC mixes a on interactive interface to apply technically in I/0 interface (refer to a graph 1) , put in very big limitation on structure and function: Above all, agree with without what define independence CNC Machining pilot opens a structure, has open sex is the open characteristic with computer inherent itself, the shot is not defined to CNC Machining characteristic, this kind of cost that draws lessons from means should rely on the structural system frame of the computer completely namely, no matter go up to do not have the consideration of pair of CNC Machining characteristic from environment of rock-bottom hardware design and operating system,PC computer serves as a general platform, accordingly cannot very good from go up at all build numerical control platform. Next, labour accuses the system of open mode numerical control of machine mode to cannot assure real time sex and dependability very well. When PC computer is moving because use current operating system, took up very great system natural resources, the task that has nothing to do with CNC Machining may be occupied went the working portion of more system, they are disturbing a system to be answered in time what machine to the spot, reduced systematic counterpoise to want to control the processing rate of incident, increased the expenditure that the system moves, what these metropolises cause a system is not stable. at 3 o'clock, the cost that labour controls system of machine mode numerical control is too high. The computer that speed of a can contented CNC Machining asks needs to invest thousands of yuan to deserve to go up again at least motion controls card, make cost very difficult reduce. And together embedded microprocessor just does not cross more than 100 yuan, be used but the chip of process designing parts of an apparatus also is controlled in 100 yuan nevertheless, the real time operating system that uses plus place is free open source code, won't software copyright uses the additional expense that go up, these make cost had very old rate reduce. Ensured patent application has very good performance/price ratio. at 4 o'clock, the network function of the system of open mode numerical control that current project controls machine mode is based on computer network, because this kind of network did not consider CNC Machining and condition monitor what flow to data of large flow signal to transmit a requirement, because this went up to restrict long-distance network of the system from speed,use capacity, basically apply to the program between the system to transmit only. Additional, what doesn't the numerical control system of NC+PC mode basically offer 2 times to develop an environment, provide the new configuration of a few interface and parameter and definition function only, still a few provide the process designing function of PLC and corresponding process designing tool, but the simple configuration that this just also measures to switch. The product of open numerical control of PC mode, implement control number of axle and the change that understand number of channels on one hand through number of interface of the increase and decrease on board card, pass the function warehouse that oneself compose builds systematic software to offer an user to realize him user to start work with enclosed form on the other hand purpose of configuration system pilot. But, of this kind of form open the ability requirement that raised to be developed 2 times to the user undoubtedly, open without specific aim, open form is chilly, maneuverability is poor. The article is based on afore-mentioned problems just about, with a view to opens the administrative levels of structural system to change compose to build, the network activation mechanism that condition monitors and the intelligence that develop platform 2 times change 3 respects to begin right brand-new the research that the structure opens numerical control system. The design end that the administrative levels of 2 open structures changes administrative levels to change a mind is convenient implementation system but expansibility and can configure a gender, this is two when judge a system to open sexual feature main index. But expansibility is to point to a system to be able to increase hardware neatly to control interface to come to those who realize a function extend with function rise; Can configuring a gender is to show the prerequisite that adding hardware texture falls, use existing rock-bottom structure module, through configure and compiling control software comes to those who implement a system be defined oneself. Administrative levels changes architecture with modular the thought is core, but distinguish again at general modular structural method. Administrative levels is changed consider a system not only the functional sex feature between each component, should consider package more between in whole structure system located the action of operating ring section and position, between clear component successive derive a relation, and through the definition actually this is planted inheritance and develop natural disposition serve as differentiate a standard of systematic component element, is not pure rely on functional standard to plan each element of the system and the relation between its. Administrative levels changes the mind that designs as frame of a kind of system not only, it can be used at all levels of systematic interior structure and exterior structure, need function and performance demand to be chased according to place when package when layer fractionize, derive successive relation and each substructure that administrative levels standard applies in package likewise. If the graph is shown 2 times, the numerical control system that administrative levels changes has 0 basic, the soft hardware interface with all package that it includes a system to control functional place basically to need and contented and general patulous and necessary function, 0 core structures that serve as a system must be had good mix internally external interface, should make sure to interior mutual news report is mixed between package already of the visit expedite, want to assure the detail screen of internal composition again, realize whole system to maintain stability and security. The add layer of 0 above builds the patulous port in 0, will expand through compensatory hardware and open software interface systematic function and promotion pilot function. Add layer cent is two kinds: Complement expands peace expands all right. Complement expands is the function that configures different control software form to implement a system through opening new interface on the foundation of original package expands; Parallel expands is the functional component that adds a coequal texture completely, will realize a department to unite kind of special control requirement or open up a new control channel. Divisional sense of these two kinds of patulous manner depends on: Make full use of two kinds of different and successive forms, namely structural sex accedes and interface sex accedes. Add and patulous abide by interface sex to accede, the form that chooses with the function embeds the interface level of systematic component, this one feature is OK standardize the implementation form of the patulous requirement to individual function conveniently, satisfy what the user appears at any time to define demand oneself. Parallel and patulous abide by structural sex to accede, duplicate with the form of functional group whole a brand-new functional passageway, form parallel control plan with original arrangement of ideas, this one feature is OK the core component that the integral sex of will open structure expands athletic control module is numerical control system, the athletic control component that is based on open structure must be had parallel expands and add and patulous form of two kinds of interface (see a picture 3) . Parallel and patulous the extension that is used at controlling number of axle, be in basic on the foundation of 3 axle control, derive the four-axle that has akin function character and 5 axes component; Add and patulous those who be used at special function is add, it is open to the user from the definition the function realizes interface, main component and expand by parallel the component that derives is had equal add and patulous interface. Graph 3 revealed basic parallel of component of control of 3 axes sport is patulous control package for four-axle and 5 axes motion, every campaign package is add and patulous complex curve interpolation, position error compensation and oscillatory condition monitor 3 special functions. The intelligence that develops platform 2 times 3 is changed the model of 2 development platform that if the graph is shown 5 times,guides a mechanism, we use a kind of pattern that conducts development, have the aid of all sorts of information libraries at predefine, the user function that uses special language description the requirement is changed into the combination of specific strategy in information library, the code that matchs through photograph of core of as small as numerical control system control next is compiled implement, will politic description is translated and pass the computer and cable of buccal by download is deferent the emulation to numerical control system develops interface. Interior of numerical control system is put in an emulation development that answers relatively to it special memery block, use at the user to revise the online desired result that makes functional code, this memery block and memery block of program of normal numerical control mutual screen, assure the security of development 2 times, return the function index of development 2 times through desired result strategy and evaluation mechanism. 2 times development environment includes to the language describes and guide a setting means of two kinds of development: The language describes means to use functional mechanism of structuralization, predefine gives the algorithmic structure with patulous system, the description that the function that the user needs to join his according to algorithmic clew only asks. The structuralization that develops platform 2 times to offer independence describes a language (if the graph shows syntactic structure 6 times) , introduce object-oriented process designing idea, with functional object group the mood of compose set prescription of the group comes the specific work status of object of component of complete description numerical control. The language describes plan, the software with the internal system of algorithmic and normative development that can adopt agile definition forms detail, apply to program of strategy of systematic ground floor define configuration oneself. The form that guides a setting to use development guide (if the graph shows development interface 7 times) word of form of to in an attempt to enquires the interface comes the patulous demand of custom-built user, use at relatively simple patulous development commonly. Union of these two kinds of mechanisms rises, the arrangement that also made development 2 times changes a structure. The system of open mode numerical control that 4 conclusion use administrative levels to change structural program and compose of small control core to build is a kind of brand-new breakthrough on architecture, the mind that administrative levels changes permeates the every component element at whole system, and guide model intelligence changes development strategy 2 times. The makes frame control logarithm the system development that administrative levels changes, use and safeguard simple connection to rise, open in the whole lifecycle implementation of numerical control equipment truly.
