| Abstract: | An electrical parameters acquisition system was designed.It takes two ARM7 processor LPC2134,the next bit using a LPC2134 and high-precision 16-bit chip synchronous sampling AD7657 to achieve the acqui-sition and calculation,and the state judge using a LPC2134 to achieve the status′s display and data storage.The in-terface of sampling module was designed.Meanwhile,the hardware of system including the memory expending part and the display part was introduced.Finally,the process flow chart debugged successfully is given.This platform is good practical,been installed in selection of small current grounded system as acquisition module. |
