Problems solved by technology

[0006] At present, in actual application, it is necessary to send the JMS message in the management information area to the JMS receiving end in the production control area. In this case, the JMS message needs to pass through the reverse isolation device, but currently there is no The method to the isolation device, therefore, it is necessary to provide a set of methods for crossing the reverse isolation device for JMS messages

Embodiment Construction

[0017] The technical solution of the present invention is: a method for JMS service across the reverse isolation device, which is used to solve the data transmission of JMS service from the safety III area to the safety I area or the safety II area in the power dispatching automation system, mainly including the JMS reverse To the proxy module and across the reverse isolation file transfer module.

[0018] The specific process is as figure 2 , the JMS service in the security zone III sends JMS messages to the JMS server in the security zone III, and the JMS reverse proxy module in the security zone III obtains the JMS message from the JMS server in the security zone III, and then passes the cross-reverse proxy module in the security zone III To the isolation device file transfer module, transfer the JMS message file across the reverse isolation device to a fixed directory in the security zone I or security zone II, and then the JMS reverse proxy module in the security zone I ...

Abstract

The invention discloses a reverse isolating device cross method for JMS (java message service). The reverse isolating device cross method is that a JMS transmitting end of an information management area sends a JMS message to a JMS server of the information management area, a JMS reverse proxy of the information management area receives the JMS message from the JMS server of the information management area and writes the message into a file under an assigned catalog of the information management area, the file under the catalog is transmitted to an assigned catalog of a generation control area through reverse isolation cross file transmission software of a reverse isolating device, a JMS reverse proxy of the generation control area reads and analyzes the file from the catalog to acquire JMS channel information and corresponding JMS message, further, the JMS reverse proxy of the generation control area sends the JMS message to the corresponding JMS channel in the JMS server according to the JMS channel information, and finally, the JMS server of the generation control area transfers the JMS message to a JMS receiving end of the generation control area.

Description

technical field [0001] The invention relates to the field of power electronics, in particular to a method and system for a JMS service cross-reverse isolation device. Background technique [0002] With the improvement of the power automation level and the development of JMS (Java Message Service, Java Message Service), in the power automation system, JMS services are more and more used in various security areas, and the security areas can be divided into security I areas , Safety II area and Safety III area, according to the requirements of the "National Power Secondary System Safety Protection Overall Plan", Safety I area and Safety II area are called production control areas, and Safety III area is the management information area, and in the production control area There is a forward isolation device and a reverse isolation device between the management information area and the JMS message transmission from the management information area to the production control area nee...
