[Summary] the major that works in the light of metric test is characteristic, make full use of the specialty of database language and technology of advanced personal computer management, the numerous management job metric test is compositive at an organic whole, raised a kind of new metric management pattern. Keyword: Calibrating calibrating plans metric management cycle [Abstract]In Accordance With The Special Characteristics Of Metering, this Paper Makes An Integration Of Metering And Testing Management Processes Based On Theharacteristics Of Database Language And Advanced Character Computer Managementtechniqies.

Therefore, a New Management Model Of Metering Is Presented.

Keywords: Metric job of   of Plan of   of Verification of   of Verification of   of Metering Management Periodic has already extremely professional powerful calibrating test technology works, again the calibrating with quite big workload plans to manage, still have instrument archives and job of test record management, especially latter, trival, repeatability is strong, the technology that affected staff of weights and measures technique badly is dedicated quality, while the made technique in insecurity works, have the government of record, archives even. Additional, check work out a scheme delimits as long-term as calibrating technology work schism is out of line each other, cannot form good feedback loop, adverse to plan canal job also. Accordingly, use technology of personal computer management, will numerous market of plan canal job at an organic whole, the system of personal computer of compositive and metric management that forms article introduction (the following abbreviation is " system " ) , to raising plan canal working level has remarkable sense. It is important that the content that 1 plan canal works mixes a job of flow plan canal is quality management branch, it is the strong safeguard that the periodic calibrating that finishs metric instrument plans. Its executive branch is a country the metric branch of special and metric orgnaization and enterprise, its work flow sees a picture 1. Graph flow chart of job of 1 plan canal from the graph 1 in can see, plan canal job shares 4 large segment, working content is as follows: ① plan: The plan personnel use according to the instrument in instrument library condition, form periodic calibrating to plan to allot branch of weights and measures technique and instrument to use an unit regularly. Use unit according to the plan, send check instrument to give weights and measures technique the department on time. ② calibrating: After branch of weights and measures technique receives instrument sending check, undertake calibrating to the instrument according to country or Cheng of established rule or practice of industry be careful in one's conduct, detailed notes checks data, undertake data processing seriously, file save. ③ feedbacks: After an instrument calibrating is finished, calibrating staff writes in time the concerned feedback information in schedule. After check of a week plans to finish, schedule should feedback in time to plan personnel. ④ amends: Plan information of personnel basis feedback, correct the use condition of corresponding instrument in instrument library in time, in order to prepare below one cycle. 4 afore-mentioned link can be divided into plan and calibrating according to working property two chunk. The plan in 4 link, feedback, revise the job that involves plan personnel, check formula is the content of staff member of weights and measures technique. Structure of 2 systems main body is aimed at the content of metric job and feature, if functional-block diagram of design system main body pursues 2. Graph system of functional-block diagram of 2 systems main body is used modular structural design, each module function is clear, distinct, total construction clarity is reasonable. Advocate below driver one class child functional module 4, except " quit a system " outside, the others is module of metric management function 3, they included what metric government works is all, also involved the data processing process with stronger sex of weights and measures technique. The functional cent that realizes them now narrates as follows: Module of ① instrument calibrating: The trends that realizes calibrating process dogs, achieve the intelligent administration of library of instrument calibrating regulations, what the calibrating that finish records is timely print. This module is involved " calibrating " link. ② plans to operate module: Implementation instrument cycle is formed automatically of calibrating plan, print, collect, newer; Finish the trends of pair of instrument libraries to safeguard. This module is involved " plan " , " feedback " , " amend " 3 link. Module of ③ computation interface: The attune that is system and exterior computation program advocate driver uses interface, achieved the classified administration of metric calculation method. Here more side overweight is safeguarded to the management of computational library. The content that the choice of 3 development platform works from metric management reachs feature of its system function, can reach metric management job has the professional quality that is similar to plan management job, 3 its module all were involved " collect " operation, namely the operation of the database. Because this chooses database language,designing platform as the system is the first choice. Consider metric calculative characteristic at the same time, the mathematical operation capability that database language provides can satisfy a requirement completely, and it still has better than average order language interfacial drive order, easier implementation human nature changes a design. Solve problem and the try out effect that design the period of time after finishing to prove from inside designing a process, language of final choice database regards development as platform is to accord with application actual. Specific arriving is choice FOXbase language, still choose FOXPRO language, or the database language of other, depend on completely him architect. But the technical limitation of the development platform itself that should notice to choose. This library structure design from the back can see in the analysis. 4 libraries structure is designed from the graph 2 can see, the maintenance that the system involved library of record library, regulations library, instrument library, computation function, because record library and computational library are simpler, instrument library is used extensively again, reason is with the designs harder regulations library in this system only here exemple, talk its way that build a warehouse. To show the convenience of the problem, see a table first please 1, this is the calibrating requirement in regulations of calibrating of high accuracy goniometer, this is the main basis that metric calibrating works, nature also is the main and referenced object that this system builds library structure. The standard of project of calibrating of calibrating requirement serial number in expressing regulations of calibrating of goniometer of 1 high accuracy is worth (″ ) calibrating category new-made is used in the 1 exterior after repairing, + + - 2 repeatability 0.

3+++3 is measured small implement light locomotive trip 0.

Prejudicial 10+-+5 measures 2+-+4 dial small implement travel is poor 0.

2+++6 accuracy 1~2+++ notes: "+ " express this project to answer calibrating, ", " express but not what calibrating thinks of the most easily also the simpliest is a regulations builds a warehouse, library structure and watch the structure of 1 agrees basically. But below this means, because have numerous rules, build numerous regulations warehouse with respect to need, the design is become " build a warehouse " design, it is a kind of cumbersome design program, not desirable. The 2nd kind of plan is a regulations is recorded as, if express 2 shown library structures,build. Express name of field of field of 2 libraries structure field type width × of C of 1 regulations name 1 standard is worth 3 projects of × of 2 projects 1C N × 4 projects × of N of code name of 1 calibrating type × of 5 projects 2C.

To expressing the library of 2 configuration, have explained at 4 o'clock: Use here " type code name " replace a list 1 medium calibrating category, because calibrating category has 3 kinds,be, if copy a watch of 1 set 1 buy, criterion every calibrating project needs to set 5 fields, the field in the library, too much. Here undertakes assorted coding formation type code name by category of 3 kinds of calibrating, share 8 codes name, part with 0 ~ 7 delegates. Try to show in programming not can. ② is expressed 2 in set 182 fields, field of name of a regulations, 60 × 3=180 calibrating project field, an indicative field. Because project of the calibrating in all regulations does not exceed 60 at most, design field of 60 calibrating project so. Indicative field place is in project N place, it is a library in (3N+2) field. Indicative value is " - " in order to is indicative the end of a regulations. ③ should choose the technology such as FOXbase to allow a field when counting less language to regard development as platform, should notice to express the library structure of 2 to accept restriction. For example the permission of FOXbase is the biggest field 128 several, can be worth calibrating project and calibrating standard right now, even calibrating type builds a warehouse respectively, all call key word with regulations name, much library is used to combine job of mode of operation when programming. In ④ library " project 01 " width extraordinary. Because all regulations are medium,the first project all is " the exterior and each part interaction " calibrating, it is literal description, reason wants when the design mature its width. Systematic design is 100 character, namely 50 Chinese characters, this is accorded with actually with the job. 5 programming are analysed 5.

1 advocate driver main program is the interface that enters each function module, also be the preparative level that has be operatinged individually. If its flow pursues 3. Graph sheet of entree of flow chart of 3 main programs uses next pulling menu design, if complete menu interface pursues 4. Graph each option of sheet of entree of basis of 4 entree odd interface, the system has kind of 3 kinds of jobs: ① library maintains an operation: Be aimed at the different operation of each libraries; ② file operates: Basically be the result in calibrating process save, of calibrating certificate consult and print; ③ maths operation operates: Of metric computation program call; 5.

This module contains module of 2 instruments calibrating 2 libraries are safeguarded child module and module of operation of a file, record the maintenance of library, regulations library and calibrating process namely. Calibrating process finishs primitive data type, save file; The inquiry that records a library to safeguard implementation calibrating to record and print; Regulations library safeguards those who realize regulations to increase, revise, consult, delete. Among them calibrating process is the working content with metric work peculiar place, extremely professional strong, its design technological process sees a picture 5. Graph calibrating of instrument of flow chart of 5 instruments calibrating is the judgement process that metrological personal decides regulations to undertake technical qualification to the instrument according to check. Primitive data should be recorded in detail in the process, undertake data processing seriously, after calibrating ends, want to save result file. From the graph 5 in can see: The actual process that the system works completely according to metric calibrating undertakes designing. After regulations of calibrating of make choice of, the system depends on the item-by-item of calibrating project order in regulations to undertake clew, after full data input is finished, in protecting existence to record a file. Here " assets number " the acquiescent file name that is record file, it also is the key word that records a library. If do not have assets number, program clew inputs file name. 5.

Calibrating of cycle of module of 3 plans operation is according to the instrument respective use condition is mixed use cycle, the quantum of time that forms according to the plan (can be month, quarter, year) to an unit / the arrangement that all metric instruments inside the branch have calibrating works. It has the following 3 features: ① plan content is sensitive to time, have periodic with repeatability; The operand that ② plans, instrument library must be adjusted in time, undertake correction; ③ is finished in cycle of a calibrating hind, the plan wants fixed pool, form forms for reporting statistics. Be aimed at above feature, systematic design requirement is sensitive to time. This module has 4 stature module, form a plan among them child module is order principal part, the key is the formation of time. The design in this system plans to be able to shift to an earlier date 5 days to allot, use automatic means completely, overcame time is changed artificially in forming a plan paragraph optional sex, make plan management stricter, more scientific. The formation that devises a plan has two kinds: One kind is normal week check plan, another kind is sampling observation plan. Latter is the sampling observation time according to set paragraph, form by random programme controll. The plan is updated is the feedback information that plans to finish according to periodic calibrating, undertake adjust and be correctioned to the condition of the instrument is being concerned in instrument library. This is the necessary work that below one cycle begins. Systematic design has change two kinds of newer way automatically with the hand. Planning collect is bring up the rear of a working rank, plan personnel has the necessary function of timely statistic to the condition of all instruments. When collect undertake automatically in order to use an unit for key word. Systematic design has appropriative to output a format. 5.

The computational program module here includes program of a metric computation call interface and library of a computation, call interface to be in charge of calculative undertaking, library is the management of responsible computation program. Program of a computation must be being calculated the ability after be being registered in library can be used to have consideration. The work out of computational program can be database language, also can be the executable program that other language weaves. The system distributes computational program into distinct category, convenient use option. If the library structure of computational library is expressed 3. The name of field of library structure field that expresses 3 computation library type width 2 programs of × of 1 method character 3 types of title character × are numeric 4 property of × are numeric   of × of character of 5 service instruction expresses × in " method " the abbreviation that is pair of calculation methods, for example " Ping Jing measures linearity " the mathematical computation means that states use Ping Jing undertakes linearity is measured. "Program name " the name of the executable program that is actual calculation method. "Type " the metric attribute that points to a method, wait like length, angle. "Property " whether is pointing to a program database language weave and become, because the system is right both call means to differ. "Service instruction " it is the simple description that uses to computational method. 6 designs sum up systematic design to have 3 characteristics: ① is metric professional: Design marriage is metric the work is real, what the design of systematic work flow and functional-block diagram accords with metric job completely is actual; ② is practical and convenient quality: Make full use of technique of personal computer management, the working market that establishs divide into equal parts of plan, calibrating, data processing at an organic whole, calibrating process and record archives management closes 2 for one, to metric management the job is brought great and convenient; ③ is applicable and extensive quality: The system uses open formula mode of operation, library structure designs the form of regulations of calibrating of complete basis country, applicable major is extensive. Anyhow, this system manages professional feature and personal computer technical close tie, collect schism at an organic whole, to metric management the job offerred a new more effective management pattern. The extensive applicability that opens as a result of its at the same time, this system has principal use port and the promotion value that have latent capacity extremely. The effect of the try out after this system designs a success is admirable also. CNC Milling CNC Machining
