Abstract

In order to develop the measurement system of automotive oxygen sensor parameters, a system hardware flat roof was set up based on DSP56F807. Data collection procedure, SCI sending procedure and interface procedure of LabVIEW and DSP were wrote with C language and LabVIEW language. The measurement method of oxygen sensor voltage signal, inner resistance and transition time was put forward. Experimental results prove that this measurement and control system can apply to detecting and analyzing a large number of the oxygen sensor parameters reliably.
