Abstract: The acquisition terminal is the intermediate link to ensure the normal operation and deep application of the power information acquisition system, If equipment failure can't be handled in time, It will directly lead to the failure of power information acquisition, such as voltage, current. Power information has great consequences, because it is related to the interests of power users and the electric power company. this paper will analysis the failure of acquisition terminal, and the disposal methods are put forward according to the analysis results, so as to recover the collection of power consumption and other information in time.
