Distribution network embedded telecontrol communication security gateway

Abstract

The invention discloses a novel secure wireless data communication device, which realizes a remote distribution automation control function in a public network on the premise of ensuring the secure and effective transmission of distribution network data. A distribution network embedded telecontrol communication security gateway is classified into a calling distribution network embedded telecontrol communication security gateway and a called distribution network embedded telecontrol communication security gateway, and comprises a main board (1). A central processing unit (2), at least one read only memory (ROM) module (3), a FLASH module (4), a general packet radio service (GPRS) module (5), a hardware encryption module (6) comprising a digital certificate, a serial interface (7), a power interface (8), a subscriber identity module (SIM) card interface (9) and an antenna (10) are integrated on the main board. The gateway further comprises a management and configuration module, a network access module, an authentication module, a virtual private network (VPN) module, a firewall module and a network serial port conversion module. The gateway can be widely applied in the field of distribution network communication construction.

Description

technical field [0001] The invention relates to an embedded telecontrol communication security gateway for a distribution network. Background technique [0002] Distribution network automation is an important means to improve power supply reliability and quality, expand power supply capacity, and realize efficient and economical operation of distribution network. It is also one of the important foundations for realizing smart grid. After nearly 40 years of development in foreign countries, distribution network automation has become an indispensable part of the modern management of power grids, and is the main means to improve user service quality and improve enterprise economic benefits. In view of the particularity of the distribution network, the mixture of various communication methods is the only way for the development and promotion of distribution automation. [0003] Compared with dispatch automation and substation automation, distribution automation is a professiona...
