Signal Collector Based on LabVIEW

Article Preview

Abstract:

After the MCU-processing, the temperature data, collected from 18B20 temperature sensors, are sent back to computer by serial port. Through the combination of computers RS232 serial port and LabVIEWs VISA, the signal can be received and be saved as text file and the save interval time may be user-define. If the temperature exceeds the limited range, it can produce warning with manners of pilot lamp or sound and at the same time the warning times are marked in txt file. This design can transmit the information from RS232 serial port to MCU and vice versa by the use of RS232.
