Measurement and control board

Flexible Automatic Measuring System-Release 5

Product information

Flexible Automatic Measuring System-Release 5 provides a variety of testing systems to suit advanced tests flexibly such as EV/HEV test by utilizing the simulation, measurement technologies, control technologies and know-how that have cultivated through FAMS-8000.

·Flexibly supports EV/HEV tests

·Control unit and measurement unit can be located separately.

·Direct sensor input to a measurement unit without convertor

·In-house production of model calculation unit allows easy maintenance and constructive system


-FAMS High-Speed Link-
By connecting 2.5 Gbps cable, data sharing and synchronism are enabled by using shared-memory.

-FAMS MCU (Model-based Control Unit)- 
Control model with MATLAB®/Simulink® can be executed in real time.
Breaking the functions down into more manageable enables high speed processing.



Drivers Display

Drivers display

·Screen switching function: measurement screen or drivers aid screen
