Design Of Testing Software Based On LabVIEW

In the storage measurement system, measurement application software is an essential component,It is responsible for communications between computer and measurement instruments, it must not only set the parameters of measurement instruments, but also need to transfer the tested data to the computer to playback ,process and record .This article uses LabVIEW virtual instrument development platform to write data acquisition and processing software that applied in the measurement system.it proposed the detailed design of software programs according to the scientific method of software engineering, and write the programming particular. achieved data acquisition, circuit programming, data read-back, Report output and other functions.Application of user events technology and ActiveX technology case produced Toolbar. The software interface is friendly, powerful, easy expansion and maintenance, there is a higher value.As a graphical programming language, the LabVIEW application software also needs optimizing. this paper analysis the main factor of impact programming performance deeply. Optimized the software structure and software diagram corresponding through the test of I/O,display,memory management,implementation process and sub vi's calling and so on. proposed some LabVIEW software programming optimizing ways in practice .This article from the perspective of software engineering to explain what is software testing, software testing objectives, software testing methods and steps, Designed a specific test case, and related modules were tested, illustrated the software testing process combined with charts and data , proved the reliability and availability of the software at a large extent.In electronic apparatus of pressure measure and Oil-Well Down-hole Test Gauge, the software has been practical applied, collected the test data, verified the system's various functions and operation. Practice shows that the functional modules of the system running in good condition, and can be effectively applied to the test system.
