Abstract: This paper uses SOPC technology and Altera corporation’s EP1C12Q240C8 as master chip to design a time synchronous data collection system. This system can be applied to real-time monitoring the components in a large aircraft, and all aspects of synchronous detection before rocket launch. It completes the clock synchronization between units based on NIOS II, and a set of flexible control and high speed self-defined internal parallel bus design.
