Abstract
This paper designs a pressure signal acquisition device for brake of rail transit, and establish a framework for the pressure signal test system based on the Single Chip Micyoco (SCM for short) C8051F350. It gives a brief introduction of the whole process for the test system, and emphatically analysis the part of the pressure sensors, the power source, the display and the communication. Lastly, we adjust the factor of the whole test system and assemble the system to test the pressure portably.
