Abstract:

We design a distributed multi-channel data acquisition instrument with ARM9 S3C2451 as the core processor.With its application in a typical automatic weather station,the external device drivers,the ARM data processing module,ZigBee networking,the data communication module and A/D sample circuit are designed and implemented. We also illustrate the software design process of the embedded system of the data acquisition instrument.Test results show that the instrument performs well in the actual application at the automatic weather station.
