Abstract

Assembly for the electronic processing of data, comprising a central module and peripheral modules linked to the central module by electrical power supply and data links, the modules comprising: a processing unit, a memory, an input/output unit and an isolation of the power and data links; the central module furthermore comprising an electrical power supply unit for the peripheral modules, a common startup unit shared by the modules, and a star communication interface with the peripheral modules; each peripheral module furthermore comprising a serial link interface to the communication interface of the central module.

Claims

1. An assembly for the electronic processing of data, comprising a central module and peripheral modules linked to the central module by power supply and data electrical links, the modules comprising:

a processing unit, a memory, an input-output unit and an isolation for the power and data links;

the central module furthermore including an electrical power supply unit for the peripheral modules, a common startup unit for the modules, and an interface for star-shaped communication with the peripheral modules;

each peripheral module furthermore including an interface for serial linking to the communication interface of the central module.

2. The assembly as claimed in claim 1, wherein the communication interface comprises a network of switches.

3. The assembly as claimed in claim 1, wherein the modules are mounted on a support structure including a partitioned bottom receiving the electrical links from the peripheral modules to the central module.

4. The assembly as claimed in claim 3, wherein the communication interface and the power supply unit for the central module are moved into the partitioned bottom.

5. The assembly as claimed in claim 3, wherein at least one of the modules is enclosed in a housing defining at least one air passage between two opposite faces of the housing.

6. The assembly as claimed in claim 5, wherein the air passage is defined between a rear face and a front face of the housing, the passage comprising at least one aperture opening onto the rear face of the housing in order to be in communication with a ventilation unit housed in the partitioned bottom and linked to the central module in order to be controlled thereby.

7. The assembly as claimed in claim 6, wherein the housing incorporates a thermally conductive frame surrounding the module and being in thermal conduction with at least one dissipating element extending into the air passage.

8. The assembly as claimed in claim 7, wherein the dissipating element is a heat pipe passing through the passage, an adjacent outer wall of the housing and the frame.

9. The assembly as claimed in claim 8, wherein the heat pipe allows a passage of air between a lower face and an upper face of the housing.

10. The assembly as claimed in claim 3, wherein at least one of the modules is enclosed in a housing made from composite material.

11. The assembly as claimed in claim 1, wherein the power supply unit is arranged to deliver at least a high-frequency alternating current and each peripheral module comprises a current-converting unit.

12. The assembly as claimed in claim 1, wherein each module is arranged to have a floating electrical reference which is specific thereto.

13. The assembly as claimed in claim 1, wherein the modules are arranged to communicate therebetween using an ETHERNET protocol.

14. The assembly as claimed in claim 1, wherein the isolation is a galvanic isolation.
