Developing a Flexible F-35 Vehicle Systems Integration Facility Data Acquisition System.



Flexible DAQ System

Figure 2 shows the general architecture of the VSIF high-channel-count data acquisition management system. 

The system is distributed across several servers to enable load balancing and achieve the required performance.

 We built the distributed vehicle management software architecture, which includes six major custom applications, to allow for future expansion of the system.

  Data Acquisition Details

Analog and digital data acquisition are performed using five PXI chassis populated with a variety of NI data acquisition boards for a total of 640 analog channels and 480 digital channels. 

The ability to mix and match different types of data acquisition dashboard while maintaining time synchronization is important for controlling the overall hardware costs of the system.


 Time synchronization is maintained support in the high-channel-count distributed system using an IRIG time signal that can be provided by the VSIF data acquisition software system or another source within the VSIF lab.
