A Study on the Sensors and Actuators Test-bed of Electronic-control Engine

The design mentality and the unique feature of sensors and the actuators of AJR electronic-control engine test-bed were introduced. The test-bed not only examines each sensor's static parameter directly, but also used tester and oscillograph to examine the data stream, the waveform, and so on. Besides the functions of the test-bed that mention formerly, the sensors and the actuators malfunction diagnosis module was designed. The test-bed was debugged when it was completed, and the results show that the test-bed achieved the desired goal, as well as meet the requirements of the actual teaching.
