| Abstract: | This paper introduced a high-performance data acquisition system based on USB and LabVIEW. The chip STM32 based on Cortex-M3 core is used for the main chip.The application software is developed by LabVIEW. The system designs signal conditioning circuit according to the animal physiological signal characteristics. The ADC embedded in STM32 could realize multi-channel synchronous analogne-to-digital conversions. The system could realize the data transmission between superior monitor and inferior computer by using USB2.0 standard interface. The system could measure the animal＇s ECG, blood pressure and other physiological parameters signal by the corresponding sensor. |
