Abstract

The invention is a distributed distribution automation station terminal DTU based on wireless transmission technology. The terminal comprises a core unit and a plurality of loop units, wherein the core unit communicates with a master station through an optical network, and each of the loop units is managed through a WIFI network; the core unit receives a command from the master station and forwards the command to the loop units for control, the loop units perform corresponding operations and control according to the situation of collection and calculation, and simultaneously report to the coreunit, and the core unit forwards the information to the distribution master station. The distributed distribution automation station terminal has the advantages of: 1) facilitating repair and maintenance and improving the efficiency for maintenance and repair since a large amount of physical cables are not needed for laying during a site operation by applying the wireless network and loop units for communication through the core unit, resulting in no need to check every cable when the equipment fails; and 2) effectively reducing the install difficulty of site operations, improving the construction and installation efficiency, and obviously reducing the cost.

Description

Technical field [0001] The invention is a distributed distribution automation station terminal DTU based on wireless transmission technology, and belongs to the technical field of distribution automation station terminals. Background technique [0002] Switching stations, ring network cabinets, and substations have been widely used in distribution automation station terminals to realize the collection, control, and fault detection of multiple lines. In the existing power distribution automation station terminal, the core unit and the return line unit need to be physically wired to collect the control communication signal volume during the installation and construction. The farther the relative physical location of the core unit and the return line unit, the more complicated the wiring. The more return lines, the more wiring is required, and the wiring process is complicated. It is difficult to overhaul when there is a problem, and it is difficult to replace the line again, which...
