| Abstract: | An intelligent compound-sensor based on redundant CAN bus is designed for measurement of fluid temperature,pressure,and flow,these three sensors and corresponding signal processing circuit are integrated. Using XC886CLM MCU deal with data acquiring and processing and CAN bus communication management.The signal oversampling design and multi-sensor data fusion are used to improve the precision of the overall measurement,the CAN bus fault diagnosis and redundant switch management are realized. |
