| Abstract: |
| Parameters of launch vehicle need to be real time monitored during long-term storage after propellant filling. In this paper, a high reliable power supply and distribution system is designed for long-term monitoring. Application software is developed based on self controllable embedded real time operating system and domestic CPU platform, and the monitor reliability is therefore improved. Since equipment fault is possible during long-term power up，we develop a redundant hot backup design and the fault equipment can be replaced without power off, thus improving system reliability. This design is validated in development engineering and applied successfully. |
