| Abstract: | In view of the current signal acquisition shortcomings for the application of space technology products,a kind of intelligent power distribution sequence controller signal acquisition based on differential conditioning circuit（DCC） is designed.By studying the transmission characteristics of DCC,analysis of DCC in AC and DC intelligent power distribution sequence controller signal acquisition under the different circumstances application to establish the optimal signal acquisition circuit and acquisition programming algorithm based on DCC.The practical application shows the signal acquisition by DCC has the advantages of suppression of common-mode,amplified differential mode,inhibition of temperature drift,high precision,and strong anti-interference. |
