The invention relates to a zone area camera recognition method. The method comprises the following steps: correspondingly obtaining a general ammeter three-phase voltage data change tendency sequenceand a single-phase ammeter voltage data change tendency sequence after acquiring the collected three-phase voltage data actual value set of the total ammeter and the voltage data actual value set of selected any single-phase ammeter, and then obtaining a change tendency goodness of fit sequence for representing the change consistency of the total ammeter each phase voltage and the single-phase ammeter voltage change, and taking the total ammeter voltage phase corresponding to the change tendency goodness of fit sequence nearest to the numerical value 1 in the change tendency goodness of fit sequence corresponding to each phase voltage in the total ammeter as the voltage phase connected with the single-phase ammeter. The accurate recognition on the voltage phase connected with each single-phase ammeter in the zone area can be accomplished without changing the existing the zone area and adding an adaptive module for a concentrator and each single-phase ammeter, and the cost for identifying the single-phase ammeter phase recognition in the zone area is effectively saved.
