Design of Embedded Intelligent Electric Instrument
Wei Xin Tian · Measurement & Control Technology · 2008
According to the using requirement in factory,an intelligent multi-function electric instrument is designed in order to improve the safety in power using.Two embedded processors,a TMS320F2812 DSP and a LPC2294 ARM,are the system core.Together with the hardware of high-speed simultaneous-sampling AD converter,parallel dual-port RAM and so on,the driver program and application program are designed optimally by layering.It is achieved that the electric parameter measure,data calculation and analysis,LCD display,alarm processing,fast signal output when accident happens,wave record,history data store and data re-store to U-disk,etc.
