| Abstract: | Combining actual needs of temperature acquisition in industrial control,this paper designs eight paths temperature acquisition system that based on S3C2440A processor and Linux operating system.The key of design is temperature acquisition module and application program.The system uses temperature sensors Pt100 to collect temperature signal,then using regulating circuit to process temperature signal,and using CPU to process data after A / D conversation.At last LCD is used to show the channel number and value of temperature.By designing hardware circuit and softerware system,the system realizes data acquisition,data transfer,data processing,and data display. |
