摘要
为了提高数据采集系统的性能,减小其体积、重量和功耗,给出了一种基于PC/104的主从式上下位机结构的数据采集系统。首先介绍了PC/104模块的特点及其应用技术,然后以PC/104为算法处理机,完成复杂算法。以数字信号处理器为接口处理机,主要完成数据转换和运算的预处理。两者通过高速DRAM互联,处理速度快。最后给出了这种数据采集系统在导航中的应用,可以满足导航系统对数据处理能力、体积、速度、重量和功耗等诸方面的要求。
To reduce the size,weight and power consumption of data acquisition system,a data acquisition system with master-slave upper-lower processors based on PC/104is developed.Firstly,the characteristics and applications of the PC/104is introduced.Then the PC/104,as a complicated algorithm processor,fulfills the complicated algorithm,and the DSP,as a interface processor,implements data conversion and pretreatment of opera-tion.The two processors are connected with a high speed DRAM bringing on working rapidly.Finally,the application on navigation is presented and the requirements for data processing capability,size,speed,weight and power consumption,etc,are met.
