and acquiring the josn format data of the topological structure from the server according to the request of the client, and converting the josn format data into the editable graph.
3. The method for monitoring topology of a distribution network based on the internet of things technology according to claim 2, wherein in the step of establishing an operable topology editing section based on a visual graphic module:
the visual browser refers to: based on the HTML5 drawing board technology, the system at least comprises key nodes, line segments, groups, basic shapes, tree structures and text graphic primitives, and graphic components capable of controlling graphic primitive operation layout through a compilable programming language;
the topological structure data in the josn format are marked by a plurality of marking fields so as to be indexed, and the marking fields at least comprise topological structure IDs, topological structure types and address or coordinate information of topological structures;
the editing processing function at least includes: positioning, querying, traversing, editing for any document.
4. The internet of things-based distribution network line topology visualization monitoring method according to claim 1, wherein the data transmission module is further configured to 3 ＝mT 1 Carrying out data fusion and transfer; the data fusion and transfer means that:
for some key point J k Corresponding data terminal Z k Data terminal Z k All the higher-level data terminals Z of (a) k-1 And all subordinate data terminals Z k+1 Counting and sequencing the transmission frequency between the two;
when the data terminal Z k Meet the conditions of data fusion and transfer, and the data terminal Z k-1 There is enough memory space, the data terminals Z are extracted in order from high to low according to the transmission frequency k A plurality of lower-level data terminals Z k+1 Corresponding topology data are transferred to the data terminal Z k-1 After which the data terminal Z is emptied k Corresponding data in until the data terminal Z k Is below a preset threshold.
