Telecontrol communication safety instrument

Abstract

The invention provides a telecontrol communication safety instrument which is convenient in communication, safe in use and not easy to be attacked. The telecontrol communication safety instrument is characterized in that three-phase electrical capacity acquisition, measurement, remote control and network communication are integrated into a whole, a 32-industrial-grage SCM (Single Chip Microcomputer) is adopted by the telecontrol communication safety instrument, multiple anti-interference measures are carried out on software and hardware, and the situation that the telecontrol communication safety instrument cannot be subjected to system halt under any conditions is ensured; by utilizing safety technologies such as dedicated digital certificate authentication for electric power dispatching, firewall and data encryption, a remote access device can be certificated, transmitted information can be subjected to encryption and digital signature, and the access range and the resource can be limited by setting a safety strategy; a TCP / IP (Transmission Control Protocol / Internet Protocol) network communication technology and an IPSEC (Inter Protocol Security) security tunneling technology are integrated into a whole, an emergency confidential data channel can be established through a GPRS (General Packet Radio Service) network mode under the situation that the a power system is in abnormal communication, and a safe and reliable transmission channel is provided for transmitting real-time data of automation of electric network management. The telecontrol communication safety instrument provided by the invention can be applied to the technical field of communication.

Description

technical field [0001] The invention relates to an instrument, in particular to a remote communication safety instrument. Background technique [0002] The power dispatch automation system has the characteristics of real-time uninterrupted production and control information security and confidentiality. Because the power communication network is combined in the overhead ground wire, and the ground wire has no effective means of melting ice, the break of the ground wire will lead to the interruption of the power communication channel, which will seriously affect the operation safety of the power system. At present, there is no special equipment for emergency data transmission channel established for power system communication. According to State Economic and Trade Commission Order No. 30 "Regulations on Security Protection of Power Grid and Power Plant Computer Monitoring System and Dispatch Data Network", State Electricity Regulatory Commission No. 5 "Security Protection Re...

AI Technical Summary

Problems solved by technology

The original protective measures of the domestic power system are also roughly similar. The security of this protective measure is very limited, and it cannot prevent illegal operations by remote users, let alone conduct post-event audits.

[0003] At present, IPSec-VPN occupies a dominant position in VPN technology, but most IPSec-VPN products are connected through the Internet. Compared with the telephone network, the security threat on the Internet is much greater, and the transmission of data and information is also easier. detected and attacked

There is also a way to establish a connection by telephone dial-up, but the allocation of the PPP dial-up IP address is dynamically allocated by the telecommunications public network, and the IP address obtained by each dial-up connection is different, so communication is very inconvenient. More importantly, the obtained IP address will be exposed on the public Internet, which poses a threat to the overall security of the system and provides opportunities for attacks

Therefore, there are deficiencies in the existing technology: communication is inconvenient, use is not safe, and it is easy to be attacked
