Design of State Data Real-time Acquisition System for Vehicle Diesel Engine

Based on the ARM10 embedded motherboard,the acquisition and treatment system of state data for diesel engine was designed with the sensors,signal conditioning modules and PC104 acquisition board.The calibration tests prove that the accuracy of the system was 1% and the system could meet the real-time acquisition requirement.The technology state monitoring of diesel engine could be realized by applying the system to real vehicle,which provided technology means for diesel engine CBM.
