| Abstract: | In order to acquire and analyze signals from oxygen sensor, first the development environment of TMS320F2812 has been chosen and functions of each module are introduced in the paper. A data acquisition system based on TMS320F2812 and LabVIEW is designed, and the accuracy of the system is proved by experiment, the data of the oxygen sensor collected by microprocessor is obtained. The reahime voltage signal of oxygen sensor is displayed in the form of dynamic in the interface of software LabVIEW, and the preservation of the signal data is completed. Thus, a reahime system monitoring of engine data is established, laying foundation for the follow-up analysis of OBD performance. |
