Transformer substation remote network test system based on one-key sequential control and control method

Abstract

The invention relates to a substation remote network test system based on one-key sequential control. The substation remote network test system comprises a remote cloud platform, an optocoupler isolation module, an external network communication module, an internal network test module and a power supply module, the remote cloud platform is used for issuing a network test instruction and receivinga network test result; the optocoupler isolation module comprises an intranet optocoupler I / O bidirectional communication module and an extranet optocoupler I / O bidirectional communication module which are electrically connected. The external network communication module is in communication connection with the remote cloud platform, interacts data through a network, is electrically connected withthe external network optocoupler I / O bidirectional communication module, and interacts data through I / O quantity, wherein the internal network test module is electrically connected with the internal network optocoupler I / O bidirectional communication module, accesses an internal network through an internal network wired network interface, performs network test, and exchanges data with the internalnetwork optocoupler I / O bidirectional communication module through I / O quantity.

Problems solved by technology

[0002] The mainstream isolation gatekeeper and physical isolation card technologies mainly include: Static Packet Filter (Static Packet Filter), Dynamic Packet Filter (Dynamic or Stateful Packet Filter), Circuit Level Gateway (Circuit Level Gateway), Application Level Gateway (Application Level Gateway), state detection Filter (StatefulInspection Packet Filter), switch agent (Cutoff Proxy) and physical isolation (Air Gap); The details cannot be known and controlled by external personnel; 2. The cost is high and the workload of deployment is heavy; 3. The system often has data real-time problems, and the network access and network output operations need to be completed after auditing and inspection processes are completed

[0005] 1. The special use environment of the substation needs to ensure 100% system safety. Even if the power supplier has passed the relevant certification, it does not substantially solve the natural problems of the technical solution, that is, there will inevitably be more places not covered by the design in the complex system. , for example: common code injection vulnerabilities are derived from the needs of functional design

[0006] 2. The cost is high and the deployment workload is heavy, so it is difficult to use it on a large scale to each substation endpoint;

[0007] 3. The problem of real-time data. The service characteristics of the substation determine the relatively high real-time requirements of the system. If audit and inspection operations are required, and if manual participation is required, the solution is actually not operable in the application background of the substation.
