Satellite-borne beam controlling computer

Abstract

The invention discloses a satellite-borne beam controlling computer. The satellite-borne beam controlling computer comprises a processor MCU, an SRAM, a FLASH memory, an interface circuit and a driving circuit, wherein the SRAM, the FLASH memory, the interface circuit and the driving circuit are electrically connected with the processor MCU. A BM3803MGRH chip is adopted in the processor MCU. Two UT9Q512K32E-SWC chips and one B8R512K8RH chip are adopted in the SRAM. Two ACT-F512K32N-060P3Q chips are adopted in the FLASH memory. A driver SN74ALVC164245DGG chip is adopted in the driving circuit. The satellite-borne beam controlling computer is suitable for being applied to the spaceflight field, can be in embedded design, can adapt to the single event effect, the total dose effect, surface charge and discharge and the like of astrospace, has the advantages of being small in size, low in weight, low in power consumption and the like, and meets the high-reliability, non-maintainability and radiation resistance and other requirements of satellite-borne electronic equipment.

AI Technical Summary

Problems solved by technology

Since the environment of the satellite platform is completely different from that of the ground and low-altitude platforms, the difficulty of circuit reliability design suddenly increases due to the space environment (total dose, single particle, internal charge and surface charge and discharge are particularly prominent), making the original simple function A large number of peripheral guarantee measures are required to make the equipment work normally; at the same time, because most aerospace products do not have maintainability, the equipment is required to operate reliably for a long time to ensure that there are countermeasures in case of failure; at the same time, space electronic equipment also requires reducing weight and volume as much as possible , reduce heat consumption; at the same time, due to the harsh environment of the space, the range of optional raw materials and components that can work in the space environment is very limited. Even the optional components have very low performance, which requires careful analysis by the designer use
