[Detailed description of the invention]
Fig. 1 is system architecture of the invention
Fig. 2 is packet transmission flow journey figure in the 4G LTE network based on VPN framework
[specific embodiment]
Present invention will now be described in detail with reference to the accompanying drawings.:
Fig. 1 is the 4G LTE network on-line early warning system construction drawing based on VPN framework, to transmission line of electricity operation data
Quickly, reliably transmit.Including sensor module, video image module, centralized control center's server, 4G wireless transmission mould
Block, front end vpn server and electric power Intranet vpn server.
The sensor module is the corresponding sensor installed on the monitoring host computer of power transmission state monitoring front end,
To environment parament, icing, shaft tower, insulator, the conducting wire monitoring etc. for acquiring transmission line of electricity, while passing through sensor network
To disassembly, cutting, steal the external force destructions such as tower material progress intellectual monitoring.Wherein, it is needed on different front end monitoring host computers
The sensor function and type of installation can be selected according to factors such as the location of monitoring host computer, environment, normal in system
During operation, accessory can be replaced arbitrarily at any time, be increased and decreased.
The video image module is that the video camera etc. installed on the monitoring host computer of power transmission state monitoring front end is set
Standby, to be taken pictures, be recorded a video to transmission line of electricity and surrounding various situations, acquired image video information can be sent out
It is sent to centralized control center's server, so that transmission line of electricity operation conditions is analyzed and handled.Wherein, different front ends monitors master
Needed on machine the performances such as memory, the function of video camera to be mounted can according to the factors such as the location of monitoring host computer, environment into
Row selection, during system operates normally, accessory can also be replaced arbitrarily at any time, be increased and decreased.
Centralized control center's server is to receive the various monitoring data in transmission line of electricity, with video, chart, song
The mode centralized displaying of line, and Intelligent statistical analysis is carried out, corresponding judging result and place are provided according to previous data record
Reason suggests feeding back to monitoring terminal, if any the included warning device progress early warning of warning information, that is, starting state monitoring terminal device
Prompt.
The 4G wireless transport module is the communication module between centralized control center's server and electric power Intranet, which adopts
The communication between server and Intranet is realized with the 4G LTE network of VPN framework.It is realized on public network using VPN technologies
The dedicated communications network between server and Intranet is set up, coded communication is carried out, guarantees the safety of data transmission;
Front end vpn server and electric power Intranet vpn server constitute double gateways of VPN framework.
On-line early warning system is implemented as follows:
Firstly the need of setting up a vpn server, centralized control center's server respectively in front end local area network and electric power Intranet
After locality connects 4G LTE network, the vpn server in electric power Intranet is connected by 4G LTE network, is then taken by VPN
Business device enters electric power enterprise Intranet.Communication data in order to guarantee data security, between vpn server sum aggregate control central server
Encryption is all carried out, it is believed that data are to carry out safe transmission in a dedicated data link, just as special
It is the same a dedicated network is set up, but actually the communication process uses the common link on internet.Utilize encryption
Technology encapsulates out a data Communication tunnel on public network, and the safety realized between centralized control center's server and electric power Intranet can
The remote access and communication leaned on.
Then the present invention carries out two-way encryption to data transmission using VPN framework, has fully ensured that the safety of data transmission
Property.But since the two-way encryption in VPN framework transmission process needs bigger bandwidth, 3G communication network is no longer satisfied
The demand of VPN framework.
The specific implementation steps are as follows for on-line early warning method of the invention:
Step 1: sensor module and video image module acquire surrounding common transmission line of electricity operation data, such as meteorological
Environmental parameter, icing, shaft tower, insulator, conducting wire monitoring etc., at the same to disassembly, cutting, steal the external force destruction such as tower material into
Row intellectual monitoring, and will individually, partly or completely acquire data according to the request of centralized control center's server and pass through 4G LTE
Wireless network transmissions are to centralized control center's server.
Step 2: centralized control center's server software is after receiving various monitoring data, in a manner of video, chart, curve
Centralized displaying, and Intelligent statistical analysis is carried out, corresponding judging result is provided according to previous data record.
Step 3: the treatment advice that analysis obtains is fed back to monitoring terminal by centralized control center's server, which passes through
The 4G LTE network of VPN framework is communicated.Wherein, vpn gateway takes double netcard structure, and outer network interface card accesses 4G using public network IP
LTE network, Intranet are clamped into electric power Intranet.
As shown in Figure 2, wherein some terminal A in centralized control center's server access electric power Intranet in 4G LTE network
Specific communication process is as follows:
(1) centralized control center's server issues access data packet, and destination address is the implicit IP address of terminal A.
(2) vpn gateway is when receiving the access data packet of centralized control center's server sending in the local area network of front end, to its mesh
Mark address is checked, if destination address belongs to the address of electric power Intranet, which is packaged, the mode of encapsulation
It is determined according to used VPN technologies, while vpn gateway can construct a new VPN data packet, and by the former data packet after encapsulation
As the load of VPN data packet, the destination address of VPN data packet is the external address of the vpn gateway of electric power Intranet.
(3) the vpn gateway of front end local area network sends VPN data packet in 4G LTE net, due to the target of VPN data packet
Address is the external address of the vpn gateway of electric power Intranet, so the data packet will be correctly transmitted to electric power by 4G LTE network
The vpn gateway of Intranet.
(4) the vpn gateway of electric power Intranet checks the data packet received, if it find that the data packet is from front end
What the vpn gateway of local area network issued, that is, it can determine that the data packet is VPN data packet, and unpacking processing is carried out to the data packet.Solution
The process of packet is mainly first to remove the packet header of VPN data packet, then data packet reverse process is reduced into original data packet.
(5) the raw data packets after reduction are sent to target terminal A by the vpn gateway of electric power Intranet, due to raw data packets
Destination address be terminal A IP, so the data packet can be sent correctly to terminal A.In terminal A, it is received
Data packet just as directly sent from centralized control center's server.
From terminal A in electric power Intranet back to the treatment process of the data packet of centralized control center's server in the local area network of front end and
The above process is the same, and a data Communication tunnel has thus been encapsulated out in public network 4G LTE network using encryption technology, real
The safe and reliable communication of terminal in the centralized control center Xian Liao server and electric power Intranet.
