Design of Remote Data Acquisition System Based on ARM

In order to realize high speed,high precision and multi-channel data acquisition,a multiply-lines power acquisition and processing system based on ARM LPC1788 was designed. At the same time,we designed a signal amplifying and adjusting circuit in order to pick up the sensors true signal. The software system was designed based on the modularization,including the modules of data acquisition,data storage and data sending by the serial interface. It realized the voltage signal data acquisition,A/D conversion,data storage and data sending. The experimental results show that the module designed by the program meets the system has high integration density,strong real-time performance,high sampling rate,high precision,high integration and flexible extension.
