The invention provides a distributed distribution network terminal device for monitoring distribution switch cabinets in real time. The distributed distribution network terminal device comprises a main control unit and at least one intelligent monitoring unit which is electrically connected with the main control unit, wherein the intelligent monitoring units are arranged in the corresponding distribution switch cabinets to be monitored; and the intelligent monitoring units and the main control unit communicate with each other through a controller area network (CAN) bus. By adoption of the technical scheme, the independent intelligent monitoring units are arranged in cabinet bodies of the distribution switch cabinets, and all intelligent monitoring units and one main control unit are connected and communicate with each other through the CAN bus, so the technical problems of limited access capacity, many access cables and large size caused by assembling all functional modules of a distribution terminal in a cabinet are effectively solved.
