Problems solved by technology

In practical applications, specific data transmission programs need to be installed in both safety I / II and safety III areas, and the system construction is relatively complicated, and most regional power supply companies have not purchased reverse isolation devices when building automation systems. It is obviously not economical to purchase a reverse isolation device for the needs of related applications, so new technologies need to be used to solve the problem of reverse data transmission

Embodiment Construction

[0023] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further explained below.

[0024] Such as figure 1 versus figure 2 As shown, the method of using the forward isolator to reverse 1-bit data to perform simple data interaction in power I and III areas is characterized in that it includes the following steps:

[0025] The forward isolation device adopts comprehensive filtering technology to intercept data packets at the link layer to realize the binding of MAC and IP addresses to prevent IP address spoofing; supports static address mapping and virtual IP technology, and has customizable application layer resolution functions. Configure the corresponding rules in the forward isolation device, and bind the internal network and external network servers through MAC, IP address and port;

[0026] Step 1. First, you need to NAT the IP of the external network server installed with ...

Abstract

The invention discloses a method for simple data interaction between an electric power region I and an electric power region III by using reserve 1bit data of a forward direction isolating device, and relates to the technical field of data interaction of electrical power systems. The method is characterized by comprising the following steps: requiring an NAT conversion on IP of an outer net server on which a server-side software is mounted, initializing Socket at an end of the outer net server firstly, then binding with a port, listening into the port, after intranet client software receives a remote control check request, building socket connection with an outer net server-side software, and matching the equipment object unique code in a scheduling command with the equipment object unique code in a remote control constrain analysis request. The method provided by the invention is reasonable, can feedback information in time and is convenient to operate.

Description

Technical field: [0001] The invention relates to the technical field of power system data interaction, and in particular to a method for performing simple data interaction in power I and III areas by using a forward isolator to reverse 1bit data. Background technique: [0002] In accordance with the requirements of the State Economic and Trade Commission [2002] No. 30 "Regulations on the Security Protection of Power Grids and Power Plant Computer Monitoring Systems and Dispatching Data Networks", the National Power Secondary System Security Expert Group has formulated relevant regulations for the specific conditions of China’s power grid dispatching system. The overall security protection plan in order to standardize and unify the planning, implementation and supervision of the security protection of China's power grid and power plant computer monitoring system and dispatch data network to prevent attacks on the power grid and power plant computer monitoring system and dispatch da...
