Pressure Sensor Testing System Based On Lab VIEW

Now all kinds of pressure sensors have been widely used in various industrial automation environment, the study and application of pressure sensors, both reflect a country’s level of technological development, but also can enhance the comprehensive national strength, but also in the rich, convenient and intelligent make an important contribution to people’s lives. Which consists of a computer assisted system for different test instrument can also become quite important laboratory test system corresponds to a pressure sensor in the test process also emerged.This paper uses the virtual instrument technology to LabVIEW platform, combined with the pressure sensor characteristics, the development of a set of computer-aided testing system. The hardware device consisting of a pressure sensor test system and related principles, completed the design and implementation of test system hardware and software. Control and data acquisition instrumentation, measurement and control systems in most experiments in the same way you can take advantage of modular programming, the development of these features into multiple separate sub-VI, for calling in various experimental module. The use of sub-VI instrument control and data acquisition sub-VI, developed a pressure sensor test system. Finally, to test experimental verification. Facts have proved that the development of a pressure sensor test system is reliable, easy to operate. Not only meet the common experimental testing requirements, while the use of each instrument can be controlled individually, with good versatility, flexibility and scalability.Pressure sensor data acquisition generally involves sensor technology, computer technology, data processing technology; data processing is divided into data acquisition, data transmission, data processing, data analysis, data storage and other operations, including data transmission and data acquisition devices between computers and through computer processing of the data processing is an important Specifically, this thesis work mainly in the following areas:1.virtual instrument technology with LabVIEW;2.for instrument control system involved;3. experimental platform based on LabVIEW pressure sensor hardware and software design;4.system. tests and conclusions.
