An improved cpci backplane for avionics computer

摘要

This is an "An improved cPCI Backplane for Avionics Computer". Improved features are implemented in this backplane to increase the reliability of the data and complete thermal monitoring of the unit. There are majorly four improved features which are implemented. First improved feature is implemented to increase the reliability of the data between cPCI controller module and the cPCI 10 module. This is achieved by establishing an Ethernet link between the controller module and IO module. Same data is transferred on cPCI bus and this Ethernet link. Second improved feature is used to monitor the temperature of the unit on different slots. Based on the temperature of the individual slots a controller is used to control the on/off of a fan once the temperature cross the critical limit. The critical limits are software configurable. This controller also sends warning signals to the pilot cockpit. Audio warning and LED warning both are made available in the cockpit. Third improved feature is used for Flexible video routing to provide the redundancy in the video input & video output. Fourth improved feature is the ease with which the unit is tested. For this purpose ATX power connector is provided on the backplane. Any power source with the ATX connector Pin assignment and current rating can be used in the lab environment to give power to the entire unit.
