Abstract

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.

Description

[0001] technical field [0002] The invention belongs to the technical field of power supply and distribution, and in particular relates to a distributed distribution network terminal device. Background technique [0003] In the existing distribution network automation system, the distribution network terminal device that realizes real-time collection and monitoring of the power distribution switchgear is mainly DTU. There are many power distribution switches in the power distribution switchgear. The DTU device uses one device to realize all distribution Real-time data acquisition and control of the switch, and complete the communication with the remote master station. figure 1 It shows the structure of an existing distribution network terminal, that is, a DTU device. The distribution network terminal device mainly includes a main processing module 11 and several collection modules 12 connected thereto, and each collection module 12 includes a An analog / switch input isolati...
