随着空间相机的应用领域从对地观测拓展到行星际探测,对系统的抗辐射能力、重量、功耗和可靠性有了更高的要求。采用耐辐射FPGA RT54SX72S和TSC695F进行了空间相机控制器的设计,用RT54SX72S实现行周期信号产生、OC指令锁存、地址译码及A/D控制锁存等相机控制功能,在提高系统可靠性的同时减小体积、减轻重量、降低功耗。给出了FPGA中各功能模块的具体实现方法和部分VHDL源码。实验结果表明,各功能模块的实现方法正确可行,相机控制器工作可靠,满足总体技术指标要求。 With the expansion of space camera applications from earth observation to interplanetary exploration, higher demands are placed on the system’s radiation resistance, weight, power consumption and reliability. The radiation controller FPGAs RT54SX72S and TSC695F were used to design the space camera controller. RT54SX72S was used to realize the camera control functions such as line cycle signal generation, OC command latch, address decoding and A / D control latch. At the same time reduce the size, reduce weight and reduce power consumption. Given the FPGA in the realization of the various functional modules and part of the VHDL source code. The experimental results show that the realization of each functional module is correct and feasible, the camera controller works reliably and meets the requirements of the overall technical specifications.
