Signal & Data Processing Rack

  1. 1. This case study showcases Mistral’s expertisein the architecture and design of a customhybrid system that supports two industry standardbus architectures VME and VPX.The CustomerThe RequirementSolution ProvidedA leading Defense Lab selected Mistral to design, build and integrate a systemcapableoffunctioningasaSignalandDataProcessing(SDP)Rack.The customer’s requirement was to design and integrate a solution that mettheir overall functional/performance criteria and adhered to longevity, productlifecyclemanagementandintegrationnorms.Mistral is a professional design services company with extensive experiencein embedded hardware and software development for Mil-Aero applications.This capability, in conjunction with partnerships with leading embeddedsolution providers like Curtiss Wright Controls Defense Solutions and WindRiver Systems, enabled Mistral to provide a complete solution to meet thecustomerexpectations.:!!!:::!!!!!!MechanicaldesignoftheSDPRackwithstructuralandthermalanalysisTherackhadtobehousedinashelteredspaceonawheeledvehicleThe rack had to be mounted on shock mounts in an air conditioned shelterand an AC vent had to be provisioned on top of the SDP rack to allowcirculationofconditionedairtotherackforcoolingpurposesThe rack had to be designed in compliance with JSS 55555 and MIL - STD461 E and would be subjected to environmental and EMI/EMC tests, atthecustomerpremisesDesignandFabricationofthehybridbackplane(VPXandVME)Generation of Wiring Charts, Inter Connection Document (ICD) andproviding cable harnesses as per the ICDThe rack had to be equipped with:Quad Power PC and Intel based processing systemQuad channel sFPDP module mounted on VPX board capable ofcommunication using sFPDP protocolVPX based Gigabit Ethernet SwitchProvision for Redundant Power SupplyPower Supplies for the entire rack.
