Monitoring System of Two Levels Non-Continuous Signal of Automotive Camshaft Sensor
A data collection terminal for performance testing of non-continuous signal of the automotive camshaft sensor is designed, Using NI-6259 data acquisition card to connect the data of collection terminal with pc, and composed of a complete monitoring system of performance testing of automotive sensor. The system can display the maximum, minimum, average, duty cycle, frequency and frequency multiplication or not of the high level and low level in real-time. And the frequency range of the measured signal is between 1Hz and 8KHz. Compare measured data with standard data, determine automatically whether it is reasonable and save them according to their classification. The test personnel are avoided to test continuously and monitor in real-time, offsetting the lack of single function of the display of test platform and running short of features of analysis and judgment.
