Abstract

A tool for the supervision and/or hypervision of a set of systems of different security levels, the systems transmitting messages, includes a display system, and further includes, for each supervised network, at least one gateway for converting the messages to image data, said gateways transmitting said image data via a one-way video link to the display system, at least one of the supervised networks being of a higher security level than the area in which the display system is placed. The invention applies notably to the centralized supervision of several information systems when said systems are subjected to different security constraints.

Claims

1. A tool for the centralized supervision and/or hypervision of a set of systems of different security levels, said systems transmitting messages, said tool comprising a display system, wherein at least one supervised system comprises one or more gateways for converting the transmitted messages to image data, said gateways transmitting said image data via a one-way link to the display system, at least one of the supervised systems being of a higher security level than the security level of the area in which the display system is placed.

2. The centralized supervision and/or hypervision tool as claimed in claim 1, wherein at least one supervised system comprises a gateway capable of assembling several messages transmitted by said supervised system in order to generate a message with coarser semantic content.

3. The centralized supervision and/or hypervision tool as claimed in claim 1, wherein the one-way links are video links carrying out a display transfer from a gateway to a screen.

4. The centralized supervision and/or hypervision tool as claimed in claim 3, wherein the display system comprises one or more screens, at least one screen being associated with each supervised system, a one-way link linking a supervised system to the screen or screens that are associated therewith.

5. The centralized supervision and/or hypervision tool as claimed in claim 1, wherein at least one one-way link is a network link capable of transporting the image data, the display system comprising at least one screen linked to a processing module receiving said images, the processing module (2233) being fitted with a software program capable of representing the images originating from several systems on the same screen.

6. The centralized supervision and/or hypervision tool as claimed in claim 1 wherein the messages are SNMP/UDP messages, the gateway comprising an adapter capable of converting the SNMP/UDP messages to images.

7. The centralized supervision and/or hypervision tool as claimed in claim 1 wherein at least one gateway is suitable for converting the messages to image data as a function of the semantic content of said messages.

8. The centralized supervision and/or hypervision tool as claimed in claim 1 wherein the messages are state indicators, the images originating from the conversion of said messages being symbolic representations of the semantic content of said indicators.

9. A method for centralized supervision and/or hypervision of a set of systems of different security levels, at least one supervised system comprising one or more gateways and sensors and/or alarm devices transmitting messages, said gateways being linked to one and the same display system, the method comprising, for at least one supervised system of higher security level than the security level of the area in which the display system is placed, at least the following steps:

a gateway comprised by said supervised system receives and converts the transmitted messages to image data;

said gateway transmits, via a one-way link, the image data to the display system.

10. The centralized supervision and/or hypervision method as claimed in claim 9, further comprising a step during which a gateway assembles several messages in order to create a message with coarser semantic content.
