In the middle of prior art, powerline network relies primarily on public network and sets up, although the overlay area of public network is wide, but public network has the problems such as secret is poor, lease expenses high, service resources cannot ensure, in particular for emergency communications such as electric power first-aids, often cannot meet the demand of use, using effect is unable to reach expection.
Summary of the invention
In view of this, the present invention is directed to above-mentioned prior art exist prior art public network cannot meet intelligent electric power communication problem, it is provided that one can electric power WiMAX private network, safe and reliable intelligent grid communication means based on LTE distributed network.
The technical solution of the present invention is, the intelligent grid communication means based on LTE distributed network of a kind of following structure is provided, the framework of described LTE distributed network includes terminal and virtualized EPC core net, described EPC core net is integrated in the middle of wireless base station device, described intelligent grid communication means includes that video monitoring communication communicates with emergency command two aspects
Described video monitoring communication comprises the following steps: all kinds of video monitoring cameras in transformer station's coverage, the core net of this transformer station is transferred back to LTE wireless mode, and it is connected to video monitoring platform by existing IP network in station, video image is selectively transferred back to provincial monitor supervision platform by the existing IP connection utilizing each transformer station after this locality terminates, it is achieved the hierarchical monitoring function of multistage access；
Described emergency command communication comprises the following steps: the wireless base station device being integrated with EPC core net is deployed on Emergency communication vehicle, image is passed back to the video monitoring platform of Emergency communication vehicle by video terminal in Emergency communication vehicle coverage in real time, and passes back to power control center by satellite or microwave wireless transmission technology.
Use above method, the present invention is compared with prior art, have the advantage that and the present invention is directed to intelligent grid to power communication system at intelligent grid video monitoring, the requirement of several aspects such as emergency repair commander, by the contrast of LTE core network centralized with tradition, show that distributed LTE core network technology is applied to intelligent grid and has the conclusion of outstanding advantage.Electric power WiMAX private network based on LTE technology, can break away from cable environment and be limited to the predicament of environmental structure, can meet again the requirement of safety and reliability, can be widely applied to the fields such as the station of electrical network, distribution automation transformation.
As preferably, described emergency command communication is further comprising the steps of: image is passed back to the video monitoring platform of Emergency communication vehicle by video terminal in Emergency communication vehicle coverage in real time, and pass back to other Emergency communication vehicles specific by satellite or microwave wireless transmission technology, to realize video interactive and call.
As preferably, in video monitoring communication steps, between the LTE distributed kernel net that different substation is disposed, there is IP reachability, interconnected by IP cloud between different substation, to realize the roaming function between different substation so that the data syn-chronization between the home subscriber of different substation and and realize backup.
As preferably, user can realize roaming switch in each website coverage, user is when roaming, the user's roaming database technology provided by LTE distributed mobile communication network, realize the roaming function in different substation or different Emergency communication vehicle coverage, described user's roaming database is distributed data base, contains attaching position register (HLR) and the function of visitor location register (VLR) in this location database.It is to say, CLR database had both included the information of HLR database, also include the information of VLR database.Meanwhile, CLR database is also used for effective call routing, and when HLR database changes, CLR database can keep automatically updating.
Detailed description of the invention
Below in conjunction with regard to specific embodiment, the invention will be further described.
