Software Development Of Measure Testing For CNG Dispensers

Modern's measure science is foundation science which pushes a science technique creative development, modern's measure profession is the foundation strength which helps to push national economy construction and national defense to constuct science development, "science and technology want development, measure beard in advance" is the theory that the Nie Rong Zhen commander-in-chief to break. Measure technical development and national economy in of applied need, always is mutually depend on save, say from a certain meaning, application and need are pushs diagraph technique to develop of motive.The usage compression natural gas is Italy that the car fuel begins from 30's in 20 centuries, the our country once used as well in 60's in 20 centuries, but wasn't high compressed of natural gas, need atmosphere to wrap, can't make widely available to expand. Lack to wait many factors increasingly and tightly because of demand and crude oil of environmental protection in the last few years, the natural gas car develops quickly in many nations, such as Italy, Holland, the United States, Russia, Japan, Korea, New Zealand, Australia, Canadian etc. country, all Be promoting strongly. Close till the end of 2003 according to the covariance, the whole world has about 1000 have another ten thousand natural gas cars, add spirit to stand more than 5000. Our country the CNG car application technique is flown to develop soon at the beginning of 21 centuries, is a particularly national"west spirit the east lose" engineering to bring the CNG car application of numerous cities factory evangel. The CNG adds spirit machine as now in 10 years lately- developed calculate tool, at on the market develop quickly, add spirit machine along with the CNG this kind of calculates an implemental birth newly, corresponding with it of calculating and examining the equipments also promises but livings.Textual CNG's adding spirit machine to calculate test software is exclusively 1 to add spirit machine to calculate test software to CNG, being mainly used for calculating examination unit Be adding spirit machine to CNG inside the magistracy of compulsive examination and management. This software adopts mature software technique and tool, developing the Microsoft Visual of the tool adoption C 6.0, backstage data usage Microsoft SQL Server, it the main function have:Add the management function of the data that the spirit station and CNG add to annoy machine to the CNG, link communication function, data processing an operation with hardware and examine certificate and record to print.This text tries hard for in the design realization of software with face to an object technique for methodology, with software engineering of thought for guide, carry on the design, analysis and realization of thorough delicacy to the contents studied.
