Data acquisition

Requirements understanding

Although their production line is properly instrumented, our customers still need an efficient tool to acquire the data. Depending on the process involved, many difficulties might rise up such as the acquisition frequency, the amount of data to be stored, the design of a user-friendly User Interface or the communication with the Programmable Logic Controllers.

We transpose our customer expectations into a reliable and customized solutions. With our long experience in software development, we are aware of the limitations and ways to solve them.

Programming language

We code our softwares in LabView a worldwide known langage dedicated to data acquistion and provided by National Instruments. Using LabView offers many advantages among which :

  • Fully integrated hardware support for many kind of acquisition,
  • Drivers available for many sensors,
  • Ease of User Interface development,
  • Ease of code sharing,

Code architecture

Our codes are based on Object Oriented programming method and more specifically we are using the Actor Framework from National Instruments. Although, manytechnics exist for creating an application in LabVIEW, we chose the Actor Framework because it focuses on being easy to learn (relative to other possibly-more-powerful tools) while mitigating risk of deadlocks/race conditions and maximizing code reuse.

The Object Oriented Programming method gives us the ability to run several actors in parallel. Typically, the first actor takes care of the images grabbing, the second manages the processing and another records the processed data. This kind of architecture ensure the ease of integrating a new actor and consequently garantees the scalability and flexibility of our solutions.

Certification

Our Certified LabView Developper (CLD) guarantees a high level of quality along the development steps.
