LabVIEW development gas regulator

LabVIEW Develop gas regulators

LabVIEW Used to collect 、 Analyze and visualize the gas regulator distribution under different pressure and flow levels , So as to provide customers with traceability 、 A reliable and easy-to-use testing process .

Gas regulator is a key component of natural gas pipeline and offshore system , Provide system pressure regulation , In some cases , Safety critical vents that provide excess gas and pressure .

The customer is at low voltage 、 Many applications operating at medium and high pressure levels produce a range of gas regulators . Due to the harsh environment and safety critical aspects , The customer must understand the outline of each gas regulator , To ensure that no matter what the system flow , It can maintain its defined regulating pressure .

After the gas regulator test requirements are added , We've developed based on DAQ Measurement system for , To analyze and test its gas regulator .

The system itself is responsible for 2 Pressure sensors and flow meters installed in the pipeline test network 4-20mA The signal , This flowmeter is specially designed to supply pressurized air to the gas regulator , So as to determine the pressure before and after the regulator and the flow of the whole system .

The application software is responsible for collecting and scaling data from the sensor at a variable speed 4-20mA The signal , And draw... In turn “ entrance ” and “ exit ” Relationship between pressure and system flow . Can be in XY Draw multiple plots on the graph , To allow customers to perform multiple tests at different flow and pressure levels , After testing , Customers can choose to export data to Excel in , Or generate a report .

Provides a single screen user interface for the operator , Minimum design , The drawing area takes precedence .

The main operator interaction is through 5 Buttons for , Allows the user to calibrate the system software , Start / Complete the drawing , Clear the drawing area and generate a test report . This simple interaction, coupled with the programmed disabling of the buttons / Enabling means that the user cannot inadvertently clear the drawing area or invalidate the data and test .

Many pop-up windows make it easy for the user to use the method of calibrating and entering test information into the application . chart 4 The calibration pop-up window... Is displayed , Allow the user to scale the input according to their own range 4-20mA The signal , This provides the user with the ability to mbar,bar and PSI Flexibility of unit running test , And define the drawing axis for reporting purposes .

Traceability is the main requirement of customers , The application provides a... Based method for exporting test data to a prefab Word Functions of the report template

By using LabVIEW Of OOP Function and based on QMH Structure , We can design and implement scalable software architectures , This architecture allows parallel communication between operations 、 Encapsulate the reference in the main application class and for DAQ、 Special classes for report generation and error reporting . Without this architecture , Applications can easily become unmanageable , what's more , For customers , It's not scalable .

LabVIEW The ease of development of the environment enables us to deal with the design process and methods flexibly , This allows us to negotiate with our customers , Whatever its size and complexity , Can quickly 、 Easily apply changes .
