Problems solved by technology

However, at present, the cost is lower, and the GPRS wireless network channel is easier to promote, but the GPRS wireless network belongs to the public network channel. After the power information collection system adopts the GPRS wireless network, the possibility of being attacked by external hackers increases. If the above problems are not resolved, it will have a major impact on the national economy and national security

Embodiment Construction

[0013] see figure 1 , in order to better understand the technical solution of the present invention, the following will be described in detail through specific embodiments and in conjunction with the accompanying drawings:

[0014] In this embodiment, the power information collection system uses the GPRS network for communication. In a network security framework for the power information collection system of the present invention, the client 1 includes: a collection terminal 11 connected in sequence, a GPRS Support point 12, GPRS service support node 13, GPRS backbone network 14 and gateway GPRS support node 15.

[0015] After the collection terminal 11 collects the user's power consumption information, it transmits the power consumption information to the GPRS support point 12 (RSC), and then the GPRS support point 12 transmits it to the GPRS service support node 13 ( Serving GPRS Support Node, SGSN).

[0016] The function of the GPRS service support node 13 is to compress ...

Abstract

The invention discloses a network security architecture for a power information acquiring system in the field of intelligent power grids. The network security architecture comprises a client end and a host end, wherein the host end comprises a gateway GPRS support node, and also comprises a gateway and a database server which are connected through a power information intranet, the gateway comprises a router, a DHCP (Dynamic Host Configuration Protocol) server and a host, the router and the DHCP server are connected with a host, the gateway and the gateway GPRS support node through an APN (Access Point Name) special line, an IP address of the APN special line is allocated by the DHCP server, and the router is used for carrying out domain name analysis on the IP address corresponding to the APN special line. The network security architecture has the beneficial effects that hacker attack from a public network can be avoided, and the security of operation of the power information acquiring system is enhanced.

Description

technical field [0001] The invention relates to a network security framework for a power information collection system in the field of smart grids. Background technique [0002] Smart grid is currently a major project that the country is vigorously promoting. An important feature of smart grid is that it can collect electricity consumption information of power users through the power information collection system, and through the power information collection system Carry out fee settlement. The power information collection system must complete the collection of power consumption information through the network. Currently, the communication channels used in the network include 230MHz dedicated line channels, optical fiber dedicated line channels and power carrier line dedicated line channels. The security of these power dedicated line channels is generally guaranteed. Guaranteed. However, at present, the cost is lower and the GPRS wireless network channel is easier to promo...
