Surveying instrument develops so far, and can be divided into three phases substantially: first stage is the conventional hardware instrument, and second stage is the virtual instrument based on software of current trend, and three phases is an intelligent controls-oriented virtual instrument.
20th century, the mid-80 at first came across the virtual instrument of the U.S., was that technical device and computer technology interpenetrate the result that mutual fusion forms.(Virtual Instrument is by application program the measurement function of computer resource (microprocessor, storer, display) and instrument hardware (A/D, D/A, digital I/O, timer, signal conditioner) to be combined formed measurement mechanism or test macro VI) to virtual instrument.The user is by friendly graphical interfaces (being called virtual panel) operational computations machine, just as the operation with traditional instrument, by built-in function realize between instrument module communication, regularly, triggering and data analysis, data representation, and form graphical interface.Its processing power of the computer technology of high speed development had satisfied the required powerful data-handling capacity of instrument already, had shown memory function and high resolution graphic presentation.The principal character of virtual instrument is:
(1) hardware capability software implementation.The function that is about to originally to be finished by hardware in the traditional instrument realizes by software, even manyly is difficult to solve or insurmountable at all problem with hardware circuit originally, also adopts software engineering to solve well.
(2) integrated, the modularization of instrumental function.Because the high speed development of large scale integrated circuit technology makes the integrated level of whole instrument system improve greatly.And modular functionality is a distinct characteristic of modern instrument instrument, and it makes instrument more flexible, and the composition of instrument is more succinct.
(3) instrument parameter is revised real time implementation.Development along with various field programmable devices and online programming technology, the parameter of instrument and meter even structure needn't just be determined when design, but can insert in real time at the scene that instrument uses and on-the-fly modify, thereby make instrument and meter adapt to on-the-spot actual thermometrically environment more neatly.
(4) instrument hardware platform universalization.Because instrument softwareization, make to share underlying instrument hardware and unite many instruments to be extended to multiple function apparatus or system and to become and realize easily.
Virtual instrument makes instrument and meter software implementation farthest, thereby makes the development of instrument cost the bullet train of computing machine development.Can think to have caused once leap in the development that appears at instrument and meter of virtual instrument, be the developing important stage of instrument.
But fasten in the version of instrument and the function of instrument and the pass of panel control, present virtual instrument and traditional hardware instruments be the difference of essence not.According to the pattern of existing virtual instrument, in order to set up an instrument, the user also must carry out " design " and " manufacturing " except the definition instrument.With the change of conventional hardware instrument software, produce also not a duck soup of a virtual instrument though that is to say existing virtual instrument, it requires the user to possess the professional knowledge and the abundant computer programming experience of instrumental science simultaneously.This forms bottleneck in the exploitation of virtual instrument, thereby directly influences its fast development.Can find a kind of new method or a kind of new model, under the prerequisite of open system, leave the right of " definition instrument ", " modification instrument " for user, and give the professional fully with the work that " design ", " assembling ", " debugging ", " combination ", " connection " etc. belong to instrument " manufacturing " aspect, thereby make all users---have profession basis and veteran and profession basis and experience all relatively the user of shortcoming can both in face of this quasi-instrument system, be in same starting line?
If invent a kind of novel virtual instrument, its inside has powerful containing ability and peripheral operation is very simple, the user is during in the face of this New Virtual instrument, need not to carry out work such as " design certainly ", " setting up certainly ", just can directly use, the direct control instrument, change the form of instrument and the function of instrument freely, make this quasi-instrument arrive the user on hand just just as one " user-friendly camera ", can realize above target.
Summary of the invention
The objective of the invention is in the test analytical instrument field, to propose a kind of new method of producing virtual instrument.According to the proposed method, test function, performance and the precision index of instrument and the corresponding construction of instrument control are combined together, be formed with the intelligent virtual control of intelligent characteristic, form a virtual instrument by these intelligent virtual controls through easy " dragging-put " mode of mouse again.Because virtual instrument carry out smart controlization, in the process of making virtual instrument, need not to carry out (hard, soft) assembling, only intelligent virtual control need be pieced together in the specific development platform of computing machine and be taken, and the location independent put of restricting relation and the intelligent virtual control that form between each intelligent virtual control to instrumental function, each intelligent virtual control can be put at random, and therefore the function of instrument, performance and precision can not change.After adopting this new model, make virtual instrument and set up virtual instrument system and will become efficiently, simply, and realized under the prerequisite of open system leaving the work of the design of instrument and establishment for expert or manufacturer and the right that will define instrument has been left the user fully for.
