Research and Application of Bus Interaction Technology in Modular Missile-borne Telemetry and Control Equipment
For a long time,the modular design has been the mainstream implementation method of missile-borne telemetry and control equipment.However,there is no uniform standard for information interaction between modules.The development unit de-fines it according to its own technical and signal characteristics.The way of definition directly affects or determines the difficulty of implementing missile-borne telemetry and control equipment.In order to develop an efficient internal interconnection technology for missile-borne telemetry and control equipment,so that the connection of modules is simpler and more efficient,and the degree of generalization is higher when the performance requirements of missile-borne telemetry and control equipment become more com-plex,this paper divides the missile-borne telemetry and control equipment into three core modules and function expansion modules,and defines an efficient module-level bus interface form and protocol.The bus includes the input and output of primary power sup-ply,secondary power supply,and internal cross-linked signals.The signal interaction adopts the form of a half-duplex bus.Each module can access the bus online and edit the bus online.Through design and experimental verification,the bus design method sim-plifies the external interface of the missile-borne telemetry and control equipment,and enables convenient and efficient online gener-ation of telemetry PCM(Pulse Code Modulation)code stream.The function expansion module can be freely added or reduced with-out increasing the hardware burden of the bus interface,making the missile-borne telemetry and control equipment highly versatile.
