| Abstract: | This paper describes a data auto-acquisition system of PC/AT buscomputer in liquid rocket engine firing tests. This system can be able to deal withboth analog information and frequency inputs, the acqusition software is written inassemble language. The sampling time is provided by internal timer interrupt ofcomputer. The special requirements of different signals for sampling periods aretaken in account of the software design. |
