Background technology
As the important component part of electrical network, can the safe operation of distribution line is directly connected to electrical network safely, efficiently, operation economically.Therefore,, in order to ensure the safe operation of distribution line, need to monitor in real time distribution line.At present, mainly rely on distribution communication network to realize for the real-time monitoring of distribution line.Under prior art condition, distribution communication network is because self structure is limit, the following problem of ubiquity: one, existing distribution communication network generally lacks rational network topology structure, the problem that causes its ubiquity fluctuation of service, poor reliability, directly affects the safe operation of distribution line thus.Its two, existing distribution communication network generally adopts wire transmission medium, cause its ubiquity networking slowly, the problem of mobile supportive difference, affect equally thus the safe operation of distribution line.Based on this, be necessary to invent a kind of brand-new distribution communication network, to solve the problem of existing distribution communication network fluctuation of service, poor reliability, slow, the mobile supportive difference of networking.
Summary of the invention
The present invention, in order to solve the problem of existing distribution communication network fluctuation of service, poor reliability, slow, the mobile supportive difference of networking, provides a kind of distribution communication network based on TD-LTE technology and tree topology.
The present invention adopts following technical scheme to realize: the distribution communication network based on TD-LTE technology and tree topology, comprises FTU, radio receiving transmitting module, TD-LTE point base station, TD-LTE center base station, dispatch server, distribution main website, infrared channel;
Wherein, the number of FTU is n; The number of radio receiving transmitting module is n; The number of TD-LTE point of base station is n; The number of TD-LTE center base station is two;
Each FTU and each radio receiving transmitting module connect one to one;
Each radio receiving transmitting module connects one to one by infrared channel and each TD-LTE point of base station;
Wherein several TD-LTE divide base station to be all connected with first TD-LTE center base station by infrared channel, all the other several TD-LTE divide base station to be all connected with second TD-LTE center base station by infrared channel, and first TD-LTE center base station is connected with second TD-LTE center base station by infrared channel; Each TD-LTE point base station forms the branch of tree topology jointly, and each TD-LTE center base station forms the trunk of tree topology jointly;
Second TD-LTE center base station is connected with dispatch server and distribution main website by infrared channel respectively;
N is positive integer.
Specific works process is as follows: the service data of each FTU Real-time Collection distribution line, and the service data collecting is sent to each radio receiving transmitting module in real time.Each radio receiving transmitting module is sent to each TD-LTE point base station by infrared channel in real time by the service data receiving.Each TD-LTE point base station is sent to first TD-LTE center base station and second TD-LTE center base station by infrared channel in real time by the service data receiving.First TD-LTE center base station is sent to second TD-LTE center base station by infrared channel in real time by the service data receiving.Second TD-LTE center base station is sent to respectively dispatch server and distribution main website by infrared channel in real time by the service data receiving.Dispatch server generates the instruction of distribution line scheduling operation in real time according to the service data receiving.The service data receiving is carried out real-time storage by distribution main website.
Based on said process, compared with existing distribution communication network, distribution communication network based on TD-LTE technology and tree topology of the present invention possesses following advantage: one, distribution communication network based on TD-LTE technology and tree topology of the present invention adopts TD-LTE point of base station and TD-LTE center base station to form tree topology, by utilizing, tree topology is easy to expand, the easier advantage of Fault Isolation for it, possesses rational network topology structure, therefore more stable, the better reliability of its operation.They are two years old, distribution communication network based on TD-LTE technology and tree topology of the present invention adopts infrared channel as transmission medium, it is by utilizing infrared channel to be difficult for being found by people and intercepting and capturing, strong security, strong interference immunity, the advantage that flexibly, is not subject to geographic range constraint easy for installation, utilize wireless transmission medium to substitute wire transmission medium, therefore its networking is faster, mobile supportive better.In sum, distribution communication network based on TD-LTE technology and tree topology of the present invention is by adopting brand new, efficiently solve the problem of existing distribution communication network fluctuation of service, poor reliability, slow, the mobile supportive difference of networking, effectively ensured thus the safe operation of distribution line, thus effectively ensured power grid security, efficiently, economically operation.
The present invention efficiently solves the problem of existing distribution communication network fluctuation of service, poor reliability, slow, the mobile supportive difference of networking, is applicable to the monitoring of distribution line.
