Design And Implementation Of Backplane Bus In Satellite Electronic Equipments

With the upgrading of the satellite’s electronic system, the IMA (IntegratedModular Avionics) has become the development trend of satellite electronic system. Inthe IMA system, equipments consist of modules which have different functions. Thisthesis designs a new kind of backplane bus，to make sure that modules inside theequipment communicates with each other efficiently and reliably. This bus is used inmeasurement and control equipments, and it integrates the bus technology with theobservation and control technology. Remote terminals of the bus can observe sensorsand control actors. This design provides a new system solution for satellitemeasurement and control equipments.Firstly, this thesis designs a system solution of a new kind of data bus, anddescribes the architecture and trigger mode of the bus based on the study of severalkinds of bus and the analysis of the demand of the measurement and control equipments.Secondly, this thesis describes the developing process of the FPGA antitype, andintroduces the design of function modules in detail. Thirdly, it designs a special test bedof the ASIC, and test the chip performance. At the end of this thesis, it summarizes thework has been done, and puts forward the improvement scheme.Test and experiment results show that: the bus interface and Control ASIC is good inperformance, performance meets the design requirements; backplane works well, themeasured velocity waveforms are relatively ideal and the design is verified feasible.
