Interface to MIL-STD-1553

Connection to MIL-STD-1553 networks

With the MIL-STD-1553 interface, you can connect a dSPACE system to the MIL-STD-1553 avionics data bus. This allows hardware-in-the-loop (HIL) simulation and rapid control prototyping (RCP) to test and develop control systems that use MIL-STD-1553.

Application Areas

The interface to MIL-STD-1553 connects a modular dSPACE real-time system to a MIL-STD-1553 network. It is used in hardware-in-the-loop (HIL) simulation and rapid control prototyping (RCP) to test and develop control systems that use MIL-STD-1553. Examples are HIL simulation for satellite avionics integration testing and component validation of aircraft flight surface actuator and engine controllers (FADECs). This interface is based on the industry-proven QPC-1553 module from GE Intelligent Platforms.


Key Benefits

The interface to MIL-STD-1553 enables you to connect your MIL-STD-1553 network directly to the real-time application running on the dSPACE processor board. It supports the DS1005 PPC Board and DS1006 Processor Board, and is also multiprocessor-capable. Each channel can be configured independently as remote terminal (RT), bus controller (BC), or bus monitor (BM). When configured as remote terminal, each channel supports up to 31 remote terminals, and in BC functionality, schedule lists are supported, with the ability to change lists dynamically during run time to facilitate fault testing for RTs.

Hardware and Software

The interface is based on the DS4504 PMC Carrier Board, which acts as a carrier for an Embedded Technology eXtended (ETX) module and a MIL-STD-1553 PCI Mezzanine Card (PMC). Data exchange between the ETX and the dSPACE processor board runs via the PHS++ (peripheral high-speed) bus and a 2-MB dual-port memory (DPMEM). A compact flash (CF) card contains the QNX run-time operating system and the ETX application. The I/O connection to the Simulink model is configured graphically by means of the MIL-STD-1553 blockset.
