Design of Three Voltage Level Test System for Auto Sensor Based on LabVIEW
A set of data acquisition terminal for automotive sensor three voltage level signal performance testing is designed. It is connected together to form a complete set of automotive sensor performance test monitoring system using NI-6259 data acquisition card and PC data collection terminal. The system can display real-time maximum, minimum and average of high voltage level, middle and low, duty cycle, frequency, and flipping or not. The measured signal frequency range is 1Hz~2.5 KHz. The measured data and the specified range of data interface is contrasted, automatically determined whether it is reasonable, and classified saved.
