An industrial control information transmission system

Abstract

The invention discloses an industrial control information sending system. The industrial control information sending system comprises an independent power supply network, a base facility, a carrier wave potential device, and a bypass processor; the independent power supply network is used for providing all the equipment except for a SCADA system with electricity; the base facility is composed of amanagement level equipment, a base equipment, and an actuating equipment; the base facility is connected with the independent power supply network through the carrier wave potential device; the carrier wave potential device is capable of realizing modulating and demodulating of digital information; the bypass processor is used for gathering and distributing of monitoring data and control data among the base facilities through electric power line carrier communication, so that an industrial control information bypass which is different from the SCADA system is constructed for sending and receiving of information. According to the industrial control information sending system, multiple channel communication is adopted for industrial control information sending and receiving, so that systemoperation stability is increased greatly, and a problem in the prior art that system anti-interference capacity of single channel type industrial control information transmission mode is poor is solved.

Description

technical field [0001] The invention relates to the field of industrial control, in particular to an industrial control information sending system. Background technique [0002] With the continuous advancement of informatization construction in the industrial control industry and the wide application of information technology, the subsequent information security issues have become increasingly prominent, and various industrial control industries have also made a lot of investment in system security construction. [0003] According to the survey on the security of various industrial control industries, the following problems generally exist in the security operation and maintenance of industrial control systems: (1) The construction of industrial control security audit is not perfect. At present, the focus of industrial control security construction is on security protection (such as adding industrial control firewalls, host hardening software, and network isolation devices) ...

AI Technical Summary

Problems solved by technology

[0003] According to the survey on the security of various industrial control industries, the following problems generally exist in the security operation and maintenance of industrial control systems: (1) The construction of industrial control security audit is not perfect

At present, the focus of industrial control security construction is on security protection (such as adding industrial control firewalls, host hardening software, and network isolation devices) and relatively little investment in security operation and maintenance audits, resulting in the lack of operation and maintenance methods

(2) The security operation and maintenance system is not perfect

The construction of industrial control operation and maintenance systems mostly focuses on the availability of business systems, and there is no relevant operation and maintenance guidance system in terms of network security and confidentiality

(3) Insufficient operation and maintenance capabilities at the security level

[0004] Use the power monitoring system of the new energy power plant to carry out network health inspection operation and maintenance services, including five aspects of security protection, including infrastructure physical security, system structure security, system body security, all-round security management, and security emergency measures. It is found that the following problems are common in each electric field: there are common problems in the safety protection of the power monitoring system, such as the weak physical security of the infrastructure, and the single-channel information transmission method. Once the network or business system is abnormal, it will seriously affect the normal operation of dispatching production
